Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the priority benefit of Chinese
Patent Applications Serial Number CN201922109142.2,
CN201922107557.6, and CN201922109138.6, filed on Nov. 29, 2019, the
full disclosure of which is incorporated herein by reference.
BACKGROUND
Technical Field
[0002] The present disclosure relates to the technical field of
high-speed connectors, particularly to a cable connector.
Related Art
[0003] Connector is a component often used in electronic
engineering, for setting up a communication between blocked or
isolated circuits in the circuit loop, having the current to
circulate to realize a predetermined function for the circuit. As
an indispensable part of electronic equipment, connectors are
produced in various types and configurations according to
applications for specific objects, frequencies, powers, and
environments. For the industries of automotive, communication
equipment, and consumer electronics, the demand for parts is
increasingly relying on the development of miniaturization,
high-speed and anti-interference, including interference caused by
high-speed transmission, such as common electromagnetic
interferences at the cable and the system (e.g., circuit board
(PCB)), and electromagnetic interferences between the cable and the
groundings.
[0004] Conventional connectors are all backplane connectors, which
are commonly used in large-scale communication equipment,
ultra-high-performance servers, and mainframe computers, industrial
computers, high-end storage devices. Along with the development of
communication technology, the increased signal/high-frequency
signal transmission speed brings the issues of interference and
crosstalk caused by distributed capacitance and inductance, and
attenuation and reflection caused by an impedance mismatch, which
needs to be resolved. The backplane connector mainly applies the
mating of a male terminal and a female terminal of a connector to
perform a connection between two circuit boards, which firstly the
male terminal is pressed onto the circuit board followed by
inserting the female terminal onto the male terminal. Considering
the interconnection between male terminal and female terminal, it
needs not only to develop corresponding male and female terminals
in response to various industries or product specifications, but
two boards of the male terminal also need to be matched with or
orthogonal to two boards of the female terminal, resulting in poor
transmission performance and poor signal masking. Besides, as the
plugging and unplugging operation between the male and female
terminals increases, it would cause wearing of the wiring terminals
when connecting and disconnecting, which could shorten the service
life of the internal wiring terminals.
SUMMARY
[0005] The embodiments of the present disclosure provide a cable
connector to solve the problem of poor transmission performance and
poor signal shielding caused by mating of male and female
terminals.
[0006] The present disclosure provides a cable connector disposed
on a circuit board, comprising a first wire-to-board connector and
at least one second wire-to-board connector. Each of the second
wire-to-board connectors is correspondingly connected to the first
wire-to-board connector through a plurality of cables. The first
wire-to-board connector and the second wire-to-board connector
respectively comprise a plurality of terminal modules. Two ends of
each of the cables are respectively connected to the corresponding
terminal module of the first wire-to-board connector and the
terminal module of the second wire-to-board connector. The
plurality of terminal modules of the first wire-to-board connector
and the plurality of terminal modules of the plurality of second
wire-to-board connectors are electrically connected to the circuit
board.
[0007] In the embodiments of the present disclosure, the terminal
module of the first wire-to-board connector and the terminal module
of the second wire-to-board connector could be a high-speed
connector, performing wire-pair shielding and total shielding,
which has an excellent performance in attenuation, low delay, and
anti-interference. In this way, high-frequency broadband
transmission can be realized and can be used in various
applications. By respectively connecting the two ends of the cable
to the terminal module of the first wire-to-board connector and the
terminal module of the second wire-to-board connector, the terminal
module of the first wire-to-board connector and the terminal module
of the second wire-to-board connector can be electrically connected
to the circuit board to replace the conventional mating of male and
female terminals for connector connection. Thus, the problems of
poor transmission performance, poor signal shielding, and unitary
applications can be well handled.
[0008] It should be understood, however, that this summary may not
contain all aspects and embodiments of the present disclosure, that
this summary is not meant to be limiting or restrictive in any
manner, and that the disclosure as disclosed herein will be
understood by one of ordinary skill in the art to encompass obvious
improvements and modifications thereto.

[0034] In the following embodiment, the same reference numerals are
used to refer to the same or similar elements throughout the
disclosure.
[0035] To improve the poor transmission performance of conventional
connectors due to poor mating between male terminals and female
terminals, a cable is used to directly connect two circuit boards
of a cable connector of the present disclosure to improve the
transmission performance. FIG. 1 to FIG. 6 are schematic diagram of
a cable connector, perspective view of a first wire-to-board
connector, schematic diagram of a terminal module installed in the
housing, exploded view of the connection between the first
wire-to-board connector and a first circuit board, perspective view
of the connection between the first wire-to-board connector and a
first circuit board, and perspective view of the connection between
the terminal module and the first circuit board of the first
embodiment of the present disclosure. As shown in the figure, a
cable connector 1 connects with the circuit board, and comprises a
first wire-to-board connector 10a, at least one second
wire-to-board connector 10b, and a plurality of cables 11. In this
embodiment, the first wire-to-board connector 10a and the second
wire-to-board connector 10b are in a one-to-one corresponding
configuration, which indicates that the number of the second
wire-to-board connectors 10b is one. The first wire-to-board
connector 10a and the second wire-to-board connector 10b
respectively comprise a housing 101 and a plurality of terminal
modules 102 (wafer). The first wire-to-board connector 10a connects
to the second wire-to-board connector 10b correspondingly by the
plurality of cables 11. The first wire-to-board connector 10a
connects to a first circuit board 20, and the second wire-to-board
connector 10b connects to a second circuit board 22. In this way,
the first circuit board 20 can be electrically connected to the
second circuit board 22. The two ends of each of the cables 11 are
respectively connected to the corresponding terminal module 102 of
the first wire-to-board connector 10a and the terminal module 102
of the second wire-to-board connector 10b. That is, the terminal
module 102 of the first wire-to-board connector 10a can be regarded
as a connector for connecting the cable 11 to the first circuit
board 20, and the terminal module 102 of the second wire-to-board
connector 10b can be regarded as a connector for connecting the
cable 11 to the second circuit board 22. Then, the terminal module
102 of the first wire-to-board connector 10a connected to the cable
11 is disposed in the housing 101 of the first wire-to-board
connector 10a to connect with the first circuit board 20, and the
terminal module 102 of the second wire-to-board connector 10b
connected to the cable 11 is disposed in the housing 101 of the
second wire-to-board connector 10b to connect with the second
circuit board 22. Both the housing 101 of the first wire-to-board
connector 10a and the housing 101 of the second wire-to-board
connector 10b could integrate the terminal modules 102, which
facilitates the first wire-to-board connector 10a and the second
wire-to-board connector 10b to be connected with the first circuit
board 20 and the second circuit board 22, respectively.
[0036] In this embodiment, the first wire-to-board connector 10a
and the second wire-to-board connector 10b are respectively
connected to the first circuit board 20 and the second circuit
board 22. The housing 101 of the first wire-to-board connector 10a
is disposed on the first circuit board 20, and the plurality of
terminal modules 102 of the first wire-to-board connector 10a is
connected to the first circuit board 20. Similarly, the housing 101
of the second wire-to-board connector 10b is disposed on the second
circuit board 22, and the plurality of terminal modules 102 of the
second wire-to-board connector 10b is connected to the second
circuit board 22. Two ends of each of the cables 11 are
respectively connected to the first circuit board 20 and the second
circuit board 22 through corresponding terminal modules 102, having
the first circuit board 20 to be electrically connected to the
second circuit board 22.
[0037] In this embodiment, the cable connector 1 is a connector
that does not require multiple pluggings and unpluggings which is
structurally stable, which can be applied to a transmission
interface of Slim SAS, Serial Attached SCSI, or Small form-factor
pluggable transceiver (SFP). The cable connector 1 of this
embodiment uses a SATA compatible cable and a point-to-point serial
transmission mode so that the installation program can be simply
implemented in a computer system. The application of a high-speed
server could also achieve demanding transmission performance
through the cable connector 1 of this embodiment. The cable
connector 1 of this embodiment is mainly in a wire-to-shield form
having excellent attenuation performance, low delay performance,
and anti-interference performance, to realize high-frequency
broadband transmission to be performed in a variety of
applications. The high-speed cables are well adapted for
short-distance wiring in data centers with a wide range and strong
integrated solution exchange capabilities. Thus, the cable 11 for
connecting the first wire-to-board connector 10a with the second
wire-to-board connector 10b is directly making the two circuit
boards electrically connected, which is capable to solve the
problems of poor signal transmission performance and poor signal
shielding for conventional connectors.
[0038] The configuration of the first wire-to-board connector 10a
of this embodiment is identical to that of the second wire-to-board
connector 10b so that only the first wire-to-board connector 10a
would be described as follows. Refer to FIG. 2 and FIG. 3 again,
and also refer to FIG. 7, FIG. 8, FIG. 9, FIG. 10, and FIG. 11,
which are perspective view of the first wire-to-board connector,
partial exploded view of the first wire-to-board connector,
perspective view of the terminal module, and exploded views of the
terminal module. As shown in the figures, the housing 101 comprises
a main body 1010, comprising an accommodating groove 10101. The
plurality of terminal modules 102 are disposed in parallel in the
accommodating groove 10101 of the main body 1010 of the housing 101
along a first direction X, wherein adjacent two terminal modules
102 are closely disposed. Each of the terminal modules 102
comprises a sheet insulating body 1021, a first cover 1022, a
second cover 1023, and a plurality of terminal groups 1024. In
other words, the plurality of terminal modules 102 comprise a
plurality of sheet insulating bodies 1021, a plurality of first
covers 1022, and a plurality of second covers 1023. The plurality
of sheet insulating bodies 1021, the plurality of first covers
1022, and the plurality of second covers 1023 are all disposed in
parallel along the first direction X in the accommodating groove
10101. The first cover 1022 and the second cover 1023 of each of
the terminal modules 102 cover the sheet insulating body 1021 at
two opposite sides along the first direction X. This indicates that
the first cover 1022 of each of the terminal modules 102 is
adjacent to the second cover 1023 of the adjacent terminal module
102, and the second cover 1023 of each of the terminal modules 102
is adjacent to the first cover 1022 of the adjacent terminal module
102. The plurality of terminal groups 1024 of each of the terminal
modules 102 are disposed in the sheet insulating body 1021 of the
terminal module 102. The plurality of terminal groups 1024 are
disposed along a second direction Y, which is perpendicular to the
first direction X. The plurality of cables 11 are respectively
connected to a corresponding terminal group 1024, and each of the
terminal groups 1024 comprises a plurality of terminals disposed at
intervals.
[0039] The bottom of the accommodating groove 10101 of the main
body 1010 of the housing 101 also comprises a plurality of terminal
openings 10102 disposed at intervals (shown in FIG. 3 and FIG. 4).
The plurality of terminal openings 10102 could match the position
of each of the terminal groups 1024 of the plurality of terminal
modules 102 of the first wire-to-board connector 10a. In this
embodiment, each of the terminal openings 10102 is a
longitudinal-shaped opening. Refer to FIG. 12, a partial schematic
diagram of the terminal group installed on the housing of the first
embodiment of the present disclosure. As shown in the figure, when
the plurality of cables 11 are connected to a plurality of terminal
groups 1024 of the plurality of terminal modules 102 of the first
wire-to-board connector 10a, the plurality of terminal modules 102
are installed in the accommodating groove 10101 of the main body
1010 of the housing 101, each of the terminal groups 1024
correspondingly passes through the corresponding terminal opening
10102, and finally, the plurality of terminals of the plurality of
terminal groups 1024 respectively pass through the corresponding
terminal openings 10102 and are inserted onto the first circuit
board 20. The cable 11 is electrically connected to the first
circuit board 20 through the plurality of terminal groups 1024. In
this embodiment, the plurality of terminals is vertically connected
to the first circuit board 20. The diameter of each of the terminal
openings 10102 could match the size of each of the terminal groups
1024, so that the plurality of terminals could be inserted into the
terminal openings 10102 correspondingly. The first circuit board 20
of this embodiment comprises a plurality of conductive holes 202,
each of which is correspondingly configured with one terminal of a
terminal group 1024. In detail, each of the terminals comprises a
contacting part 10241 and an electrical connecting part 10242. The
contacting part 10241 is connected to the cable 11, and the
electrical connecting part 10242 is connected to the first circuit
board 20. The connecting process of the electrical connecting part
10242 to the first circuit board 20 is going to be described
herein. In this embodiment, the electrical connecting part 10242 of
each of the terminals is correspondingly inserted into each of the
conductive holes 202 in a press-fitting manner to form an
electrical connection. The electrical connecting part 10242 of each
of the terminals comprises a fisheye component used by the
electrical connecting part 10242 of each of the terminals to be
press-fitted into the conductive hole 202 of the first circuit
board 20. The fisheye component comprises two elastic parts
elastically contracted when under squeezing, so that the related
structure is deformed during the press-fitting process. Thus, the
electrical connecting part 10242 of each of the terminals could be
smoothly inserted into the conductive hole 202 of the first circuit
board 20 through the fisheye component. When the fisheye component
passes through the corresponding conductive hole 202, the two
elastic parts of the fisheye component would abut against the
conductive hole 202 of the first circuit board 20 to effectively
prevent the electrical connecting part 10242 of each of the
terminals from detaching from the first circuit board 20, and
further ensure a firm connection between the terminals and the
circuit board in low ohmic resistance. Besides, the fisheye
component can be installed on the first circuit board 20 with only
a slight pressing force, so that the terminal having the fisheye
component could be easily installed onto the first circuit board
20. That is, the connection process between the terminal and the
first circuit board 20 does not require any soldering. Thus, the
terminal having the fisheye component is detachable to match
smaller conductive holes 202 of the first circuit board 20. For
example, the distance between adjacent conductive holes 202 can be
extremely short and the diameter of the hole aperture can be
extremely small (for example, the diameter of the press-fitting
hole is about 14 mil). There are still many ways to connect the
plurality of terminals of the plurality of terminal groups 1024 to
the first circuit board 20, such as surface mount technology (SMT)
or soldering. Thus, how the plurality of terminal groups 1024 are
connected to the first circuit board 20 would not be limited
herein. Since the structural configuration of the first
wire-to-board connector 10a is identical to that of the second
wire-to-board connector 10b, and the structural configuration of
the second circuit board 22 is identical to that of the first
circuit board 20, the assembly method for the second wire-to-board
connector 10b with the second circuit board 22 is identical to that
for the first circuit board 20 with the first wire-to-board
connector 10a. The method for assembling the second wire-to-board
connector 10b with the second circuit board 22 would not be
described herein.
[0040] In this embodiment, the structural configuration of the
terminal module 102 of the first wire-to-board connector 10a is
identical to the terminal module 102 of the second wire-to-board
connector 10b, which are both connected to corresponding circuit
boards by press-fitting. The terminal module 102 of the first
wire-to-board connector 10a and the terminal module 102 of the
second wire-to-board connector 10b can also be connected with
corresponding circuit boards by surface mount technology (SMT) or
soldering.
[0041] The structural configuration of each of the terminal modules
102 in the first wire-to-board connector 10a or the second
wire-to-board connector 10b is described as follows. In this
embodiment, the terminal module 102 solves the problem of
insufficient structural strength and poor performance of
conventional terminal modules by providing comprehensive designing
and improvements for the structural strength, assembly efficiency,
and signal transmission performance for the terminal module 102.
Back to FIG. 10 and FIG. 11, the sheet insulating body 1021 of the
terminal module 102 comprises a first insulator 1021a and a second
insulator 1021b connected to the first insulator 1021a. The first
insulator 1021a comprises a plurality of first accommodating
grooves 10212a disposed on a surface of the first insulator 1021a
away from the first cover 1022 along the second direction Y. The
plurality of terminal groups 1024 are disposed on the first
insulator 1021a along the second direction Y, and protrude from the
bottom of the first insulator 1021a. The plurality of terminal
groups 1024 respectively correspond to the plurality of first
accommodating grooves 10212a.
[0042] The second insulator 1021b comprises a plurality of second
accommodating grooves 10212b, and the plurality of second
accommodating grooves 10212b are disposed along the second
direction Y and are corresponding to the plurality of first
accommodating grooves 10212a. The plurality of cables 11 are
connected to the second insulator 1021b. Each of the cables 11 is
disposed in the corresponding second accommodating groove 10212b.
When the second insulator 1021b is connected to the first insulator
1021a, each of the first accommodating grooves 10212a is connected
to the corresponding second accommodating groove 10212b, and the
first accommodating groove 10212a and the second accommodating
groove 10212b accommodate one cable 11 (as shown in FIG. 9)
together. Since the first accommodating groove 10212a and the
second accommodating groove 10212b are designed to match the
appearance of the cable 11, the plurality of first accommodating
grooves 10212a match with the plurality of second accommodating
grooves 10212b. For example, the first accommodating groove 10212a
and the second accommodating groove 10212b are both half-arc
grooves, so an accommodating groove with an annular wall can be
formed when the first accommodating groove 10212a is connected the
second accommodating groove 10212b. Thus, the accommodating groove
covers a part of the cable 11, and the cable 11 is electrically
connected to the corresponding terminal group 1024.
[0043] Regarding the assembly of the terminal module 102, it is
first to install the first insulator 1021a on the first cover 1022.
Then the second insulator 1021b is installed on the first insulator
1021a, and the second cover 1023 is installed on the first
insulator 1021a. In this way, the first insulator 1021a and the
second insulator 1021b are disposed between the first cover 1022
and the second cover 1023.
[0044] The detailed structural configuration and assembly process

the first insulator 1021a. Each of the tenon components 10221
comprises two tenons 10221a symmetrically disposed. The plurality
of first securing holes 10222 pass through the first cover 1022,
and are respectively disposed below the corresponding tenon
component 10221. Each of the first securing holes 10222 is disposed
between two tenons 10221a of the corresponding tenon component
10221. Each of the first positioning parts 10223 protrudes from a
surface of the first cover 1022 close to the first insulator 1021a
along the first direction X, and is disposed between the tenon
component 10221 and the first securing hole 10222 corresponding to
the tenon component 10221. Each of the openings 10224 is disposed
on a surface of the first cover 1022 away from the first insulator
1021a, and is disposed between two adjacent tenon components 10221.
Each of the elastic piece groups 10225 is respectively disposed in
the corresponding opening 10224. The elastic piece group 10225 of
this embodiment comprises two elastic sheets disposed at intervals
with lead angles.
[0045] The first insulator 1021a comprises a plurality of engaging
parts 10213, a plurality of first securing blocks 10214, a
plurality of second securing blocks 10215, a plurality of first
limiting parts 10216a, a plurality of through holes 10217, a
plurality of embedding openings 10218, and two blocks 10219. The
plurality of engaging parts 10213 are disposed along the second
direction Y, and respectively correspond to the plurality of first
accommodating grooves 10212a. In this embodiment, each of the
engaging parts 10213 comprises two symmetrical engaging holes
10213a. The two engaging holes 10213a penetrate the first insulator
1021a along the first direction X and are disposed on two sides of
the first accommodating groove 10212a. The plurality of first
securing blocks 10214 are disposed on a surface of the first
insulator 1021a close to the first cover 1022 along the second
direction Y, and are respectively disposed below the corresponding
engaging parts 10213. The plurality of second securing blocks 10215
are disposed on a surface of the first insulator 1021a away from
the first cover 1022 along the second direction Y. The plurality of
second securing blocks 10215 are respectively disposed opposite to
the plurality of first securing blocks 10214, which indicates that
each of the second securing blocks 10215 and the first securing
block 10214 corresponding to the second securing block 10215 are
disposed along the first direction X, and are disposed below the
corresponding engaging parts 10213. Each of the first limiting
parts 10216a is disposed between the engaging part 10213 and the
first securing block 10214 corresponding to the engaging part 10213
and is disposed on the first insulator 1021a along the first
direction X. In this embodiment, the first limiting part 10216a is
a through hole. Each of the through holes 10217 is disposed between
the engaging part 10213 and the first limiting part 10216a
corresponding to the engaging part 10213 and penetrates the first
insulator 1021a along the first direction X. Each of the embedding
openings 10218 is disposed between two adjacent engaging parts
10213. The two blocks 10219 are disposed on two sides of the first
insulator 1021a.
[0046] FIG. 13 is a schematic diagram of the connection between the
terminal group and the cable of the first embodiment of the present
disclosure. FIG. 14 is an enlarged view of area A of FIG. 11. As
shown in the figure, each of the terminal groups 1024 of this
embodiment comprises four terminals disposed at intervals. The four
terminals comprise two signal terminals 1024a and two ground
terminals 1024b. The two signal terminals 1024a are disposed
between the two ground terminals 1024b. Each of the signal
terminals 1024a comprises a contacting part 10241 and an electrical
connecting part 10242. The two contacting parts 10241 of the two
signal terminals 1024a are disposed in the first limiting part
10216a and are exposed from the first limiting part 10216a. The two
electrical connecting parts 10242 of the two signal terminals 1024a
are disposed below the first insulator 1021a. Each of the ground
terminals 1024b comprises a contacting part 10241 and an electrical
connecting part 10242. The two contacting parts 10241 of the two
ground terminals 1024b are disposed in the first limiting part
10216a and exposed from the first limiting part 10216a. The two
electrical connecting parts 10242 of the two ground terminals 1024b
are disposed below the first insulator 1021a. A part of each of the
ground terminals 1024b is disposed in an adjacent embedding opening
10218, and each of the embedding openings 10218 comprises two
ground terminals 1024b of two adjacent terminal groups 1024. Thus,
in this embodiment, the width of the contacting part 10241 of the
signal terminal 1024a is narrower than the width of the contacting
part 10241 of the ground terminal 1024b. Besides, in this
embodiment, the distance between the two electrical connecting
parts 10242 of the two signal terminals 1024a is different from the
distance between the two contacting parts 10241 of the two signal
terminals 1024a. In this embodiment, the distance between the two
electrical connecting parts 10242 of the two signal terminals 1024a
is greater than the distance between the two contacting parts 10241
of the two signal terminals 1024a. In this way, the plurality of
distances between the two electrical connecting parts 10242 of the
two signal terminals 1024a and the two electrical connecting parts
10242 of the two ground terminals 1024b are identical, facilitating
the manufacture of the circuit board.
[0047] The second insulator 1021b further comprises a plurality of
second limiting parts 10216b, a plurality of first positioning
grooves 10220a, and a plurality of second positioning grooves
10220b. Each of the second limiting parts 10216b is disposed on a
surface of the second insulator 1021b close to the first insulator
1021a along the second direction Y, and corresponds to the
plurality of second accommodating grooves 10212b. Each of the
second limiting parts 10216b is disposed below the corresponding
second accommodating groove 10212b. In this embodiment, the second
limiting part 10216b is a bump. The plurality of first positioning
grooves 10220a are disposed on a surface of the second insulator
1021b close to the first insulator 1021a along the second direction
Y. The plurality of second positioning grooves 10220b are disposed
on a surface of the second insulator 1021b away from the first
insulator 1021a along the second direction Y. The plurality of
second positioning grooves 10220b are respectively disposed
opposite to the plurality of first positioning grooves 10220a. The
first positioning groove 10220a and second positioning groove
10220b opposite to the first positioning groove 10220a are disposed
between the second accommodating groove 10212b and the second
limiting part 10216b corresponding to the second accommodating
groove 10212b. Refer to FIG. 13 and FIG. 15, an enlarged view of
area B of FIG. 9, as shown in the figures, the details of the
connection between each of the terminal groups 1024 and cable 11 is
described as follows. Each of the cables 11 comprises a plurality
of wires. The plurality of wires are respectively connected to the
terminals of the corresponding terminal group 1024. In this
embodiment, the plurality of wires comprises a pair of signal wires
111a and two ground wires 111b. When the second insulator 1021b is
installed on the first insulator 1021a, the pair of signal wires
111a of each of the cables 11 are respectively connected to the two
signal terminals 1024a in the corresponding first limiting part
10216a. Practically, each of the signal wires 111a is connected to
the corresponding signal terminal 1024a by soldering. The signal
wires 111a of this embodiment are differential signal wires, one of
the two signal wires 111a is used to transmit positive signals, and
the other is used to transmit negative signals. The signal
transmitted by the pair of signal wires 111a is a differential
signal, which is transmitted by the signal terminal 1024a connected
to the signal wire 111a. The two ground wires 111b of each of the
cables 11 are respectively connected to the two ground terminals
1024b in the corresponding first limiting part 10216a so that the
ground terminals 1024b can be grounded. Each of the cables 11 of
this embodiment further comprises an insulating covering part 112
and an insulating layer 113. The pair of signal wires 111a and two
ground wires 111b are disposed side by side in the insulating
covering part 112 inside the cable 11. The two ground wires 111b
are respectively disposed on two sides of the pair of signal wires
111a. The insulating layer 113 covers the pair of signal wires 111a
and is disposed between the ground wire 111b and the corresponding
signal wires 111a.
[0048] The second cover 1023 further comprises a plurality of
second positioning parts 10231 and a plurality of second securing
holes 10232. The plurality of second positioning parts 10231 are
disposed along the second direction Y and protrude from a surface
of the second cover 1023 close to the second insulator 1021b. The
plurality of second securing holes 10232 respectively correspond to
the plurality of second positioning parts 10231. Each of the second
securing holes 10232 is disposed below the corresponding second
positioning part 10231. Two sides of the second cover 1023 are
further provided with engaging openings 10233 respectively.
[0049] During assembling, when the first cover 1022 is installed
onto the first insulator 1021a, which is, two tenons 10221a of each
of the tenon components 10221 can be correspondingly tenoned into
the two engaging holes 10213a of the corresponding engaging part
10213. So, the first insulator 1021a can be installed on the first
cover 1022. The plurality of first securing blocks 10214 of the
first insulator 1021a and the plurality of first securing holes
10222 are structurally and positionally matched. The plurality of
first securing blocks 10214 are correspondingly engaged with the
plurality of first securing holes 10222. In this way, the assembly
of the first cover 1022 and the first insulator 1021a can be more
stable through the engagement of matched securing.
[0050] Next, the second insulator 1021b is installed onto the first
insulator 1021a. Practically, the plurality of second limiting
parts 10216b of the second insulator 1021b is correspondingly
engaged into the plurality of first limiting parts 10216a, and each
of the positioning parts 10223 passes through the corresponding
through hole 10217 of the first insulator 1021a and passes through
the plurality of first positioning grooves 10220a of the second
insulator 1021b. In this way, the second insulator 1021b can be
installed on the first insulator 1021a. When the second insulator
1021b is installed on the first insulator 1021a, each of the first
accommodating grooves 10212a and each of the second accommodating
grooves 10212b would form an accommodating groove presenting an
annular wall, which can cover a part of the cable 11. In some
embodiments, the second insulator 1021b is formed on the first
insulator 1021a by injection molding, and they could cover the
cable 11 together.
[0051] Then, the second cover 1023 is installed on the second
insulator 1021b. Each of the second positioning parts 10231 of the
second cover 1023 is correspondingly engaged with each of the
second positioning grooves 10220b. In this way, the overall
assembly can be more stable and accurately positioned.
Particularly, since the plurality of first limiting parts 10216a of
the first insulator 1021a are respectively disposed above the
corresponding second securing block 10215, the plurality of second
securing blocks 10215 would be exposed when the plurality of second
limiting parts 10216b of the second insulator 1021b are
correspondingly engaged with the plurality of first limiting parts
10216a. Thus, when the second cover 1023 is finally assembled, each
of the second securing blocks 10215 of the first insulator 1021a
would be correspondingly engaged in each of the second securing
holes 10232 of the second cover 1023. Besides, the two engaging
openings 10233 on two sides of the second cover 1023 are
respectively engaged with the two engaging blocks 10219 on two
sides of the first insulator 1021a to allow each of the engaging
blocks 10219 to pass through and secured to each of the engaging
openings 10233. In this way, the second insulator 1021b can be
secured between the first insulator 1021a and the second cover
1023, thereby improving the stability. Finally, the bonding of the
first cover 1022 and the second cover 1023 can be spot soldering or
other bonding methods to increase the overall connecting stability.
The first cover 1022 and the second cover 1023 are designed as lead
angle type to ensure reliable mechanical and electrical connection,
thereby reducing mechanical stress for each of the cables 11 and
each of the terminal groups 1024. The lead-in and polarization of
the lead angle could prevent contacting damage and to provide a
reliable connection.
[0052] In some embodiments, the first insulator 1021a is formed to
secure the terminal group 1024, and then the cable 11 is disposed
on the first insulator 1021a and is connected to the terminal group
1024. Next, the second insulator 1021b is formed on the first
insulator 1021a and covers the cable 11 and the terminal group
1024. Then, the first cover 1022 and the second cover 1023 are
installed on the first insulator 1021a and the second insulator
1021b respectively.
[0053] In this embodiment, a surface of the first cover 1022 close
to the first insulator 1021a further comprises a plurality of first
contacting parts 10226 disposed along the second direction Y. Each
of first contacting parts 10226 is disposed between two adjacent
tenon components 10221 and is disposed below the corresponding
opening 10224. A surface of the second cover 1023 close to the
second insulator 1021b further comprises a plurality of second
contacting parts 10234 disposed along the second direction Y. Each
of the second contacting parts 10234 is disposed between two
adjacent second securing holes 10232. In this embodiment, the
material of the first cover 1022 and the second cover 1023 is
conductive, such as metal, conductive plastic, electroplated
plastic. When the first cover 1022 is installed on the first
insulator 1021a, the plurality of first contacting parts 10226
respectively enter the corresponding embedding openings 10218. Each
of the first contacting parts 10226 is in contact with two ground
terminals 1024in the corresponding embedding opening 10218, so that
the first cover 1022 would be in contact with the ground terminal
1024b to be grounded. When the second cover 1023 is installed to
the first cover 1022, the plurality of second contact parts 10234
respectively pass through the second insulator 1021b and enter the
corresponding embedding opening 10218. Each of the second
contacting parts 10234 is in contact with two ground terminals
1024b in the corresponding embedding opening 10218 so that the
second cover 1023 would be in contact with the ground terminal
1024b to be grounded. The grounding of the first cover 1022 and the
second cover 1023 can protect the signal generated by the terminal
module 102 from being electromagnetically interfered by other
terminal modules 102, and keep the electromagnetics generated by
the terminal module 102 to interfere with other terminal modules
102. In this way, the signal transmission performance of each of
the terminal modules 102 can be effectively improved, thereby
improving the overall signal transmission performance.
[0054] FIG. 16 is a schematic diagram of the terminal base
assembled with terminals of the first embodiment of the present
disclosure. As shown in the figure, each of the terminal modules
102 of this embodiment further comprises a plurality of terminal
bases 1025. The plurality of terminal bases 1025 are disposed at
the bottom of the first insulator 1021a along the second direction
Y, and are disposed on the corresponding terminal group 1024. Each
of the terminal bases 1025 comprises at least one through hole
1025a. In this embodiment, the number of through holes 1025a is
one. Two electrical connecting parts 10242 of the two signal
terminals 1024a of each of the terminal groups 1024 pass through
the first through hole 1025a and do not contact a sidewall of the
through hole 1025a. That is, a gap exists between the two
electrical connecting parts 10242 of the two signal terminals 1024a
of each of the terminal groups 1024 and the sidewall of the
corresponding through hole 1025a. Two electrical connecting parts
10242 of the two ground terminals 1024b of each of the terminal
groups 1024 pass through the terminal base 1025. The electrical
connecting part 10242 of each of the ground terminals 1024b is in
contact with the terminal base 1025. In this embodiment, the
material of the terminal base 1025 is conductive, such as
electroplated plastic, conductive plastic, or metal. The material
for the terminal base 1025 would not be limited thereto, but only
to make the terminal base 1025 conductive. Each of the terminal
bases 1025 is in contact with two ground terminals 1024b of the
corresponding terminal group 1024 to be grounded. Each of the
terminal groups 1024 is provided with a terminal base 1025.
Interfering between the plurality of terminal groups 1024 of one
terminal module 102 can be avoided during signal transmission by
the plurality of terminal bases 1025. In this way, the signal
transmission performance of the terminal module 102 can be further
improved, thereby improving the overall signal transmission
performance. When the first cover 1022 and the second cover 1023
are installed on the sheet insulating body 1021, the first cover
1022 and the second cover 1023 are in contact with the terminal
base 1025. This ensures that the first cover 1022 and the second
cover 1023 can be grounded, thereby ensuring that the plurality of
terminal modules 102 would not cross-interfere during the signal
transmission process.
[0055] When the assembly of the terminal module 102 is completed,
the plurality of terminal modules 102 would be installed in the
housing 101. The plurality of elastic sheet groups 10225 of the
first cover 1022 of each of the terminal modules 102 abut against
the second cover 1023 of adjacent terminal module 102. In this way,
it can be ensured that the plurality of first covers 1022 and the
plurality of second covers 1023 of the plurality of terminal
modules 102 of one wire-to-board connector are grounded, thereby
ensuring that there would not be inference between the plurality of
terminal modules 102 to improve the signal transmission performance
of the cable connector 1 in the overall signal transmission
process.
[0056] In this embodiment, the structural configuration of the
housing 101 of the first wire-to-board connector 10a is identical
to the housing 101 of the second wire-to-board connector 10b, so
the housing 101 of the first wire-to-board connector 10a would be
described in the follows. The housing 101 of this embodiment,
having good structural strength, assembly efficiency, and assembly
variability, can improve the concern of the unity of assembly
variation of the housing of the conventional wire-to-board
connectors. FIG. 17 to FIG. 19 are perspective view and exploded
views of the first embodiment of the present disclosure. As shown
in the figure, the housing 101 of this embodiment further comprises
a first end cover 1011 and a second end cover 1012. The first end
cover 1011 is disposed on one end of the main body 1010, and the
second end cover 1012 is disposed on the other end of the main body
1010. The second end cover 1012 is opposite to the first end cover
1011 with the main body 1010 in between. The first end cover 1011
further comprises a plurality of first partition parts 10111
disposed at intervals, and the second end cover 1012 comprises a
plurality of second partition parts 10121 disposed at intervals.
The plurality of first partition parts 10111 and the plurality of
second partition parts 10121 are alternately disposed. That is,
each of the first partition parts 10111 is disposed between two
adjacent second partition parts 10121, and each of the second
partition parts 10121 is disposed between two adjacent first
partition parts 10111. In this embodiment, the structural
configuration of the first end cover 1011 is identical to that of
the second end cover 1012, and the structural configuration of the
plurality of first partition parts 10111 is identical to that of
the plurality of second partition parts 10121. In this embodiment,
the positions where the plurality of first partition parts 10111
are disposed on the first end cover 1011 are different from the
positions where the plurality of second partition parts 10121 are
disposed on the second end cover 1012. Each of the first partition
parts 10111 and each of the second partition parts 10121 would not
be positioned correspondingly at all events, even, such as
displacing the plurality of first partition parts 10111 by the
width of one partition part at the same time, or displacing the
plurality of second partition parts 10121 by the width of one
partition part at the same time. Thus, when the first end cover
1011 and the second end cover 1012 are installed on the main body
1010, the plurality of first partition parts 10111 of the first end
cover 1011 and the plurality of second partition parts 10121 of the
second end cover 1012 would be alternately arranged.
[0057] In one embodiment, two end edges of the main body 1010
respectively have a plurality of buckles 10104 and two first
engaging parts 10105 disposed at intervals. The plurality of
buckles 10104 are disposed on an end edge of the bottom of the
accommodating groove 10101 of the main body 1010. The two first
engaging parts 10105 are respectively disposed on the two sidewalls
of the accommodating groove 10101 and are close to the bottom of
the accommodating groove 10101. In one embodiment, the first end
cover 1011 further has a plurality of first openings 10112 and two
second engaging parts 10113. The plurality of first openings 10112
are disposed in parallel on the plurality of first partition parts
10111 of the first end cover 1011 and are disposed in a plurality
of gaps, each of which is between two adjacent first partition
parts 10111. The plurality of first openings 10112 penetrate the
first end cover 1011 along the first direction X. The two second
engaging parts 10113 are respectively disposed on two sides of the
first end cover 1011. The first end cover 1011 further comprises a
plurality of first embedding parts 10114 and a plurality of second
embedding parts 10115. The plurality of first embedding parts 10114
are respectively disposed on the corresponding first partition part
10111, and each of the second embedding parts 10115 is disposed
between two adjacent first partition parts 10111. In detail, each
of the first embedding parts 10114 comprises two first sidewalls
10114a disposed at intervals and a first embedding groove 10114b
disposed between the two first sidewalls 10114a. The two first
sidewalls 10114a perpendicularly extend in a direction closing to

first end cover 1011 close to the main body 1010. Similarly, the
second embedding part 10115 comprises two second sidewalls 10115a
disposed at intervals and a second embedding groove 10115b disposed
between the two second sidewalls 10115a. The two second sidewalls
10115a of the second embedding part 10115 are respectively adjacent
to side surfaces of the corresponding first partition part
10111.
[0058] The second end cover 1012 comprises a plurality of second
openings 10122 and two third engaging parts 10123. The plurality of
second openings 10122 are disposed in parallel on the plurality of
second partition parts 10121 of the second end cover 1012 and are
disposed in a plurality of gaps, each of which is between two
adjacent second partition parts 10121. The plurality of second
openings 10122 penetrate the second end cover 1012 along the first
direction X. The two third engaging parts 10123 are respectively
disposed on two sides of the second end cover 1012. The second end
cover 1012 further comprises a plurality of first embedding parts
10124 and a plurality of second embedding parts 10125. The
plurality of first embedding parts 10124 are respectively disposed
on the corresponding second partition part 10121, and each of the
second embedding parts 10125 is disposed between two adjacent
second partition parts 10121. In detail, the structural
configuration of the first embedding part 10124 and the second
embedding part 10125 of the second end cover 1012 is identical to
that of the first embedding part 10114 and the second embedding
part 10115 of the first end cover 1011. The first embedding parts
10124 of the second end cover 1012 comprises two first sidewalls
10124a disposed at intervals and a first embedding groove 10124b
disposed between the two first sidewalls 10114a. The two first
sidewalls 10124a perpendicularly extend in a direction closing to
the accommodating groove 10101, and protrude from a surface of the
second end cover 1012 close to the main body 1010. The second
embedding part 10115 of the second end cover 1012 comprises two
second sidewalls 10125a disposed at intervals and a second
embedding groove 10125b disposed between the two second sidewalls
10125a. The two second sidewalls 10125a are respectively adjacent

10121.
[0059] When the first end cover 1011 and the second end cover 1012
are installed to the main body 1010, the plurality of first
embedding parts 10114 of the first end cover 1011 and the plurality
of second embedding parts 10125 of the second end cover 1012 are in
one-to-one correspondence, and the plurality of second embedding
parts 10115 of the first end cover 1011 and the plurality of first
embedding parts 10124 of the second end cover 1012 are in
one-to-one correspondence. The plurality of buckles 10104 of the
main body 1010 are correspondingly engaged and secured to the
bottoms of the plurality of second embedding grooves 10115b of the
plurality of second embedding parts 10115 of the first end cover
1011 and the plurality of second embedding grooves 10125b of the
plurality of second embedding parts 10125 of the second end cover
1012. Besides, the structural configurations and positions of each
of the first engaging parts 10105 close to the first end cover 1011
matches with those of the second engaging part 10113 of the first
end cover 1011, and the structural configurations and positions of
each of the first engaging parts 10105 close to the second end
cover 1012 matches with those of the third engaging part 10123 of
the second end cover 1012. For example, the first engaging part
10105 is a stepped-shaped groove, and the second engaging part
10113 and the third engaging part 10123 are stepped-shaped bumps.
The second engaging part 10113 and the third engaging part 10123
are respectively engaged with and secured to the corresponding
first engaging parts 10105. In this way, the first end cover 1011
and the second end cover 1012 can be disposed on the main body
1010. In one embodiment, the bottom surfaces of the first end cover
1011 and the second end cover 1012, and the bottom surface of the
main body 1010 are coplanar. So, they can be stably disposed on the
circuit board. In addition to the above engaged-securing method to
assemble the main body 1010, the first end cover 1011 and the
second end cover 1012, the main body 1010, the first end cover 1011
and the second end cover 1012 can also be integrally formed into
one piece.
[0060] Back to FIG. 3, FIG. 8 to FIG. 11, the housing 101
accommodates at least one terminal module 102. Two sides of the
first cover 1022 of the terminal module 102 are provided with a
first embedding bump 10227 respectively. Two sides of the second
cover 1023 of the terminal module 102 are further provided with a
hook 10235 and a second embedding bump 10236 respectively. The hook
10235 is disposed above the second embedding bump 10236. The two
first embedding bumps 10227 respectively correspond to the two
second embedding bumps 10236. When the terminal module 102 is
disposed in the accommodating groove 10101 of the main body 1010,
two sides of each of the terminal modules 102 are respectively
disposed on the first partition part 10111 and in a gap between two
adjacent second partition parts 10121 or are respectively disposed
on the second partition part 10121 and in the gap between two
adjacent first partition parts 10111. When two ends of the terminal
module 102 are respectively disposed on the first partition part
10111 and in the gap between two adjacent second partition parts
10121, the two hooks 10235 of the terminal module 102 are
respectively engaged with the first opening 10112 of the first
partition part 10111 and the second opening 10122 between two
adjacent second partition parts 10121. The first embedding bump
10227 and the second embedding bump 10236 of each of the terminal
modules 102 close to the first end cover 1011 are disposed in the
first embedding groove 10114b of the first embedding part 10114 of
the first end cover 1011. The first embedding bump 10227 and the
second embedding bump 10236 of each of the terminal modules 102
close to the second end cover 1012 are disposed in the second
embedding groove 10125b of the second embedding part 10125 of the
second end cover 1012. When two sides of the terminal module 102
are respectively disposed on the second partition part 10121 and in
the gap between two adjacent first partition parts 10111, the two
hooks 10235 of the terminal module 102 are respectively engaged in
the second opening 10122 of the second partition part 10121 and in
the first opening 10112 between two adjacent first partition parts
10111. The first embedding bump 10227 and the second embedding bump
10236 of each of the terminal modules 102 close to the first end
cover 1011 are disposed in the second embedding groove 10115b of
the second embedding part 10115 of the first end cover 1011. The
first embedding bump 10227 and the second embedding bump 10236 of
each of the terminal modules 102 close to the second end cover 1012
are disposed in the first embedding groove 10124b of the first
embedding part 10125 of the second end cover 1012. In this way, the
plurality of terminal modules 102 can be stably disposed in the
corresponding housing 101. As the plurality of first partition
parts 10111 of the first end cover 1011 and the plurality of second
partition parts 10121 of the second end cover 1012 are alternately
disposed, after installation according to the above assembly method
and so on, the plurality of terminal modules 102 can be alternately
disposed in the accommodating groove 10101. In this way, the
plurality of terminal groups 1024 of each of the terminal modules
102 and the plurality of terminal groups 1024 of adjacent terminal
modules 102 can be disposed alternately. Meanwhile, each of the
cables 11 is connected to the corresponding terminal group 1024,
allowing the plurality of cables 11 on each of the terminal modules
102 and the plurality of cables 11 on the adjacent terminal module
102 to be alternately disposed. This design helps the connectors to
avoid signal crosstalk and effectively improve the signal
transmission performance of the cable connector 1 during signal
transmission process. The two first embedding bumps 10227 of the
first cover 1022 and the two second embedding bumps 10236 of the
second cover 1023 respectively contact with the corresponding
ground terminals 1024b, allowing the plurality of terminal groups
1024 in each of the terminal modules 102 to be completely protected
by grounded first cover 1022 and the second cover 1023 to prevent
the signal transmitted by the plurality of terminal groups 1024
from being interfered. Thus, each of the terminal modules 102 could
have excellent signal transmission performance during the signal
transmission process, allowing the cable connector 1 to perform
excellent signal transmission.
[0061] FIG. 20 is a schematic diagram of a cable connector of the
second embodiment of the present disclosure. As shown in the
figure, the cable connector 1 of this embodiment is different from
the cable connector of the first embodiment in that the number of
second wire-to-board connectors 10b of the cable connector 1 is
two, one of which is connected with one end of the plurality of
cables 11 and the plurality of terminal modules 102 of the first
wire-to-board connector 10a, and the other one is connected with
the other end of the plurality of cables 11 and the plurality of
terminal modules 102 of the two second wire-to-board connectors
10b, wherein the plurality of terminal modules 102 of the first
wire-to-board connector 10a are inserted into the corresponding
first circuit board 20, and the plurality of terminal modules 102
of each of the second wire-to-board connectors 10b are inserted
into the corresponding second circuit board 22. When the plurality
of cables 11 are 48 differential pair cables, the first
wire-to-board connector 10a can be used as a connecting end for the
48 differential pair cables, and the two second wire-to-board
connectors 10b can be the connecting ends of the 24 differential
pair cables respectively. Particularly, the first wire-to-board
connector 10a can respectively connect the output signal
differential pair to one or more second wire-to-board connectors
10. The first wire-to-board connector 10a could form 48
differential pairs through the plurality of cables 11, and with the
mutual corresponding connection of the plurality of cables 11, the
first circuit board 20 can be directly and electrically connected
to the two second circuit boards 22 respectively. The number of
cables 11 can also be adjusted appropriately depending on actual
applications, and it is not limited thereto. The number of second
wire-to-board connectors 10b can also be adjusted appropriately
according to requirements, and variously formed and configured
wire-to-board connectors can be interactingly matched, and then the
plurality of circuit boards can be electrically connected directly,
having the connectors to be competitive in the related
industries.
[0062] In summary, the present disclosure proposed a cable
connector. By respectively connecting the two ends of the cable to
the terminal module of the first wire-to-board connector and the
terminal module of the second wire-to-board connector, the terminal
module of the first wire-to-board connector and the terminal module
of the second wire-to-board connector can be electrically connected
to the circuit board to replace the conventional mating of male and
female terminals for connector connection. Thus, the problems of
poor transmission performance, poor signal shielding, and unitary
applications can be well handled. Moreover, the terminal module has
also been improved, which improves the connecting firmness between
the cable and the circuit board and the signal transmission
capacity. Along with the alternated arrangement of the plurality of
terminal modules, the plurality of cables are arranged alternately
to avoid signal crosstalking effectively.
