DETAILED DESCRIPTION
[0033] Refer to FIG. 1 and FIG. 2, an extending device 100 for
signal transmission of a first embodiment includes a first riser
card 110, a signal coupling card 130, and a second riser card
120.
[0034] Refer to FIG. 1 and FIG. 2, the first riser card 110
includes a first circuit board 112, a first electric socket 114,
and a first electric connector 116.
[0035] The first electric socket 114 is disposed on a side surface
of the first circuit board 112. The first electric connector 116 is
disposed at an edge of the first electric circuit board 112 and is
electrically connected to first electric socket 114 via the circuit
that the first circuit board 112 provides. The first electric
socket 114 set forth includes, but not limited to, PCI, AGP, PCIE,
ATA, SATA socket or the combination thereof. Terminal pins of the
first electric connector 116 are correspondence with the
communication protocol of the first electric socket 114. In one
example, the first electric connector 116 is a terminal assembly
independently disposed on the first circuit board 112; in other
example, first electric connector 116 a card edge connector of the
first circuit board 112. The first electric connector 116 is used
to insert into to a main socket 210 of a mainboard 200, while the
communication protocol of the main socket 210 is the same with that
of the first electric socket 114.
[0036] Refer to FIG. 2, the signal coupling card 130 includes a
third circuit board 132, a second electric connector 134, and a
third electric connector 136. The third circuit board 132 is a
printed circuit board which is rigid for the purpose of giving
support. The third circuit board 132 is equipped with metalized
layers for constructing signal transmission circuit having good
signal transmission performance and reducing signal attenuation and
interference.
[0037] The second electric connector 134 and the third electric
connector 136 are respectively disposed on two opposite edges of
the third circuit board 132, and the second electric connector 134
is electrically connected to the third electric connector 136 via
the third circuit board 132. The second electric connector 134 is
used to insert into the first electric socket 114. Similarly, the
second electric connector 134 and the third electric connector 136
can be disposed terminal assemblies independently disposed on the
signal coupling card 130 or card edge connectors of the signal
coupling card 130.
[0038] Refer to FIG. 2, the second riser card 120 includes a second
circuit board 122, a second electric socket 124, and one or more
extending sockets 126. The second electric socket 124 and the
extending sockets 126 are respectively disposed on both side
surfaces of the second circuit board 122, the third electric
connector 136 is used to insert into the second electric socket
124, and the extending sockets 126 are electrically connected to
the second electric socket 124.
[0039] The extend device 100 can be equipped with one or more
extending socket 126. For example, the extend device 100 in this
embodiment includes two extending sockets 126, in which the two
extending sockets can be identical or in the different types. For
example, the two extending sockets 126 are identical in the
condition that the main socket 210 of the mainboard 210 only
supports one communication protocol; on the other hand, the two
extending sockets 126 respectively supports two different
communication protocols in the case that the main socket 210
supports the combination of two different communication protocols.
The communication protocols set forth includes, but not limited to,
PCI, AGP, PCIE, ATA or SATA.
[0040] Refer to FIG. 1, through the combination set forth, the
first circuit board 112 of the first riser card 110 and the second
circuit board 122 of the second riser card 120 are disposed in
parallel, the third circuit board 132 of the signal coupling card
130 is perpendicular to the first circuit board 112 and the second
circuit board 122.
[0041] A signal transmission path between the first electric
connector 116 of the first riser card 110 and the third electric
connector 136 of the signal coupling card 130 is formed. Therefore,
the object to extend the signal transmission path between the first
electric connector 116 and the extending sockets 126 is
achieved.
[0042] The extending sockets 126 can be inserted by different types
of expansion cards, so that the connection between expansion cards
and the mainboard 200 can be extended by the extending device 100
for signal transmission. In particular, in the art the expansion
cards are perpendicular to the mainboard 200 when inserting into
the main socket 210 and the height of expansion cards is restricted
by the height of the computer chassis. For example, if the computer
chassis is a low-profile chassis, such as a 1U server chassis, the
height of expansion cards is extremely restricted. In the
embodiments of this disclosure, the expansion cards are turned to
be parallel to the mainboard 200 via this extending device 100 and
extend beyond the mainboard 200 partially, thus the height of
expansion cards will not be restricted by the height of the
chassis. Furthermore, the third circuit board 132 of the signal
coupling card 130 is a printed circuit board, which provides a well
signal transmission and reduces signal attenuation and
interference.
[0043] Refer to FIG. 3, a mainboard assembly of a second embodiment
includes a mainboard 200 and an extending device 100 for signal
transmission.
[0044] The mainboard 200 includes a main socket 210 and other
electronic components of the mainboard 200. The electronic
components set forth include central processing unit sockets,
memory sockets, interfaces of storage device, system chips and so
on. The electronic components and basic architecture of the
mainboard 200 of this disclosure are is a part of the art and well
known by a person ordinarily skilled, the detail will not be
omitted hereinafter.
[0045] The extending device 100 for signal transmission include a
first riser card 110, a signal coupling card 130, and a second
riser card 120. The features of the extending device 100 of this
embodiment are identical to that of the first embodiment, the first
electric connector 116 of the first riser card 110 is used to
insert into the main socket 210 of the mainboard 200 and extends
the ports that the main socket 210 provides to the extending socket
126.
[0046] Furthermore, the main socket 210 is disposed at the edge of
the mainboard 200. The third circuit board 132 is arranged in
parallel to the mainboard 200 and is extended in the direction that
away from the mainboard 200, so that the second riser card 120 that
contacts to the third circuit board 132 (the coupling card 130)
will not overlap the mainboard 200, and an opening of the extending
socket 126 is in a direction that away from the mainboard 200 as
well. On the other word, while the expansion card inserts into the
extending socket 126 of the second riser card 120, the expansion
card extends beyond the mainboard 200 rather than reclose above the
mainboard 200. Hence, it has no necessary to partially remove the
PCB of the mainboard 200 to evade the expansion card because the
mainboard 200 is not located below the expansion card. For example,
in the art when an expansion card is a graphics card, the PCB of
mainboard 200 has to be partially removed to evade GPU chip for the
purpose of configuring a cooling component like a radiator. In this
disclosure, the graphics card extends beyond the mainboard 200,
thus it has no necessary to cutoff or partially remove PCB of the
mainboard 200. On the other word, the mainboard 200 can be a
standard and universal mainboard instead of customized one.
[0047] The mainboard assembly set forth can be fit for a
low-profile chassis, such as a 1U server chassis. The expansion
cards are turned to be in parallel to the mainboard 200 via this
extending device for signal transmission. Hence, the height of
expansion cards will not be restricted by the low-profile
chassis.
[0048] The third circuit board 132 of the signal coupling card 130
is a printed circuit board, which provides a well signal
transmission and reduces signal attenuation and interference.
