Description
This invention relates to a multi-terminal connector assembly to be
employed for connecting wiring harnesses through an intercepting
wall such as a dash panel in a motor-car provided between an engine
room and an instrument room.
In the conventional wiring harness in a motor-car passing through
the dash panel, there are employed grummets for shutting off from
the instrument room poisonous gases, noises etc. which occur in the
engine room. However, this method of wire connection has a defect
that it requires much trouble and time to fit sets of wires to the
dash panel one by one.
It is, therefore, an object of the present invention to provide a
multi-terminal connector assembly which can abbreviate the time of
connecting wiring harnesses in the both rooms through an
intercepting wall and facilitate a systematic connection of the
wiring harnesses according to the number of wires required.
It is another object of the present invention to provide a
multi-terminal connector assembly capable of employing terminal
plates of the same shape in each unit of the connector assembly
thereby to simplify a manufacturing and repairing process,
permitting a mass production based on a quality control.
Essentially, according to this invention, there is provided a
multi-terminal connector assembly which comprises a panel connector
element including a plurality of blocks with a desired number of
terminal plates; an attachable connector element corresponding to
each of said blocks; said panel connector being provided with a
flange adapted to be fitted to an intercepting wall around its

present invention.
Character A designates a panel connector element which comprises,
in FIG. 1, four female portions A.sub.1a, A.sub.1b, A.sub.1c and
A.sub.1d in its inner part, and four male portions A.sub.2a,
A.sub.2b, A.sub.2c and A.sub.2d in its outer part. Said panel
connector element is made of an insulating material such as a
synthetic resin. A pair of a female and a male portions A.sub.1a
and A.sub.2a form one block having 16 terminals, in FIG. 1,
A.sub.1b and A.sub.2b form another block having 14 terminals,
A.sub.1c and A.sub.2c form a still another block having 12
terminals and A.sub.1d and A.sub.2d form a still another block
having 18 terminals.
Each female and male portion is provided with a terminal plate B as
shown in FIG. 3.
The terminal plate B, referring to FIGS. 4 and 5, is preferably
made of high-conductive metals and has, at its tail portion, a
connecting portion 1 to a wire and, in front of said connecting
portion 1, a resilient contact plate 2. Under said resilient
contact plate 2, there is formed a projection 3 cut and erected out
of the terminal plate B, and a pair of wings 4 are formed on both
sides of the resilient contact plate 2. The connecting portion 1 to
a wire has, at its central portion, an edge 1a cut and erected out
of the terminal plate B and, on both sides thereof, a plurality of
holding members 1b edged at the top, by which a wire 5 is securely
connected to the terminal B through its insulating coating keeping
electric connection.
In the female portion A.sub.1 is provided a base plate 6 which is
associated with a wall 6' connecting to said base plate 6 to form a
room R. A groove 8 for receiving the terminal plate B is formed on
said base plate 6 with a partition 7. Inside said groove 8, there
are formed, on both lateral walls, a concave 9 for receiving said
wings 4 of the terminal plate B, and on the base plate 6, a concave
10 for receiving said projection 3 of the terminal plate B. A
bulkhead 11 abutting on said partition 7 is provided in the back
portion of the room R.
The male portion A.sub.2 has only a base plate 6 as mentioned above
but no wall as denoted by numeral 6'. It is to be noted that the
male portion A.sub.2 is defined in a size insertible into the room
R of the confronting female portion A.sub.1. Between the female
portion A.sub.1 and the male portion A.sub.2 is formed a space into
which the base plate 6 of the confronting female portion A.sub.1
can be inserted.
Into the grooves 8 of the female portion A.sub.1 and the male
portion A.sub.2, a required number of terminal plates B are
inserted slidably from the back. The terminal plate B is so adapted
to be securely fixed in the predetermined position with its wings 4
registered in the concaves 9 and with its projection 3 registered
in the concave 10.
Referring to FIG. 6, character C designates an attachable connector
adapted to be connected to each block of the panel connector
element A. The illustrated attachable connector has 14 terminals
permitting connection thereof to said female and male portions
A.sub.1b and A.sub.2b, one block of the panel connector element,
having 14 terminals. The attachable connector C is in its structure
identical with the block having a pair of the female and the male
portions A.sub.1 and A.sub.2 of the panel connector element, and
employs the same terminals B as described in the panel connector
element A. A male portion C.sub.2 of the attachable connector C can
be inserted into the female portion A.sub.1 of the panel connector
element A and, at the same time, a female portion C.sub.1 of the
same can receive the male portion A.sub.2 of the panel connector
element A.
There is further provided a cut-out portion 12 formed at the
central portion of the wall 6' of the female portion C.sub.1 and a
hook swingeably supported by a supporting portion 13 over said
cut-out portion 12 and adapted to be fitted to a lock projection 15
formed on the outer surface of the panel connector element A.
The attachable connector C is of the type which can be connected to
another identical attachable connector by turning one of the two
upside down. Therefore, the identical lock projection 15' is formed
on said connector C on the opposite side to the hook 14, and a
groove 16 is formed in the female portion A.sub.1 of the panel
connector element A to receive said projection 15'.
The panel connector element A is provided with an integrally formed
flange 17, and springy lock projections 18 are formed thereon as
depicted in FIG. 1. Said flange 17 except said lock projections 18
is covered with a grummet which has double ridges formed integrally
thereon. Said ridges on the grummet are pressed by the force of
insertion when the panel connector element A is attached to an
opening 19 in a dash panel P of a motor-car, then, the lock
projection 18 are engaged with the dash panel thereby to firmly
secure the panel connector element A to the dash panel
air-tightly.
As apparent from the foregoing description according to the present
embodiment, not only the panel connector element can be simply
attached to the dash panel of a motor-car, but also air-tightness
can be assured by the grummet provided on the flange of the panel
connector element.
Further according to the present embodiment, the panel connector
element includes a plurality of blocks each having a pair of the
female and the male portions of a desired terminal number, and so,
respective wiring harnesses can be connected systematically.
Referring to FIGS. 7 to 13, there is illustrated a combined type
multi-terminal connector assembly which is another embodiment of
this invention.
Character D designates a female connector, E a male connector, Fa
supporting frame and G a terminal plate.
In each female connector D are provided a pair of base plates 21
]-shapedly confronting each other in a sectional view and walls 22
to form a plurality of rooms R. On the both walls 22 forming a room
R are formed concaves 23 and on the bottom surface of the room R is
formed a stepped portion 24 for securing the terminal plate G. The
back portion of a pair of said base plates 21 is divided in two by
a central partition 25.
The terminal plate G, identical with the terminal plate B in the
former embodiment, has, at its tail portion, a connecting portion
26 to a wire and, in front of said connecting portion 26, a
resilient contact plate 28. Under said contact plate 28, there is
formed a projection 30 erected out of the terminal plate G, and a
pair of wings 29 are formed on both sides of the contact plate 28.
The terminal plate G is inserted into the female connector D
slidably from the back and so adapted to be securely fixed in the
predetermined position with its wings 29 registered in the concaves
23 and with its projection 30 registered in the stepped portion
24.
The female connector D includes a first female connector D.sub.1
and a second female connector D.sub.2.
Each of said first and second female connectors is provided on its
both lateral faces with hooks 31 for engaging with the supporting
frame F. In the forward portion of the first female connector
D.sub.1 are further provided a lock projection 32 for the male
connector E and contact projections 33 and 33' to contact with the
under surface of the supporting frame F and with a projection 34 of
the second female connector D.sub.2 which is also adapted to
contact with the under surface of the supporting frame F.
The supporting frame F has a size suitable for holding a desired
number of the female connectors D.sub.1, D.sub.2 combined and a
flange 38 integrally formed therearound. On the inner faces of the
supporting frame F are formed concaves 35 and stepped portions 36
corresponding to said hooks 31 of the female connector D and
further formed cut-out portions 37 corresponding to said lock
projection 32.
For combining a desired number of the female connectors D, a first
and a second female connectors D.sub.1 and D.sub.2 are adequately
arranged according to the size of the supporting frame F. Then the
supporting frame F is placed on the arranged female connectors and
pressed downward until the under surface thereof gets in touch with
the projections 33 and 34. The hooks 31 are engaged with the
stepped portions 36 of the frame F thereby to securely fasten the
female connectors D to the supporting frame F.
The male connector E has a base plate 21 projecting forward from
the back portion having the central partition 25 and walls 22 on
the both sides of said base plate 21 to form a room R similarly to
the female connector D to hold the terminal plate G.
The male connector includes a first male connector E.sub.1 and a
second male connector E.sub.2. On the both lateral faces of the
first male connector E.sub.1 are provided hooks 39 swingeably
supported by a supporting portion 40 for engaging with said
projection 32 of the first female connector D.sub.1, and on the
upper and lower surfaces thereof are formed projected portions 43
with notches 41.
The second male connector E.sub.2 is provided with projections 42
for engaging with said notches 41 and stepped projections 44 for
contacting with said projected portions 43.
A desired number of said first and second male connectors E.sub.1,
E.sub.2 are adequately combined by fitting said projection 42 into
said notch 41 until the projected portion 43 gets in touch with the
stepped projection 44.
The thus combined male connectors E are inserted into the female
connectors D previously combined and held by the supporting frame F
to enable the terminal plates G respectively in the both connectors
D and E to contact with each other.
As apparent from the above description, the female connectors
combined and held by the supporting frame serve as a panel
connector element to be attached to an intercepting wall and the
male connectors combined in one block serve as an attachable
connector element.
In FIG. 8, there is shown, in vertical section, the present
embodiment employed in a motor-car for connecting the wiring
harnesses in the engine room and in the instrument room to each
other through the dash panel. The panel connector element
comprising female connectors D is inserted in an opening 49 of the
dash panel 48 from the engine room. The supporting frame F with its
flange 38 covered with a grummet 45 is fitted to the dash panel 48
and secured by bolts 46 and nuts 47 to perfectly separate the
instrument room from the engine room.
Then the male connectors connected to the wiring harness in the
instrument room and united in one block are inserted into the
female connectors to give an electrical connection.
As described above, the female and the male connectors can be
adequately combined according to the number of wires required
thereby to permit division of wiring work and abbreviate the
executing time.
Further according to the present invention, since the connectors
are put to use by combining a desired number of the same, a
diversed cover can be employed for each block for water proof.
In the both embodiment according to the present invention, the
terminal plates of the same structure can be advantageously
employed for both the female and the male portions and connectors,
thereby to facilitate and simplify a manufacturing process and a
quality control.
Since the panel connector element is securely fixed to the
intercepting wall such as a dash panel of a motor-car by means of
the described fixing members, thereby effectively shutting off
poisonous gases, noises etc.
