Detailed Description
The invention will be described in detail with reference to the following drawings, which are provided for illustration purposes and the like:
fig. 1 is a schematic diagram of a server. Referring to fig. 1, in the present embodiment, a server 10 includes a motherboard area 12, a relay board area 14 and an expansion area 16. Expansion board 20 (fig. 2) or other expansion components are disposed in expansion area 16, and such expansion board 20 is electrically connected to a motherboard (not shown) in motherboard area 12 through a relay board (not shown) in relay board area 14. In the present embodiment, the height of the server 10 is, for example, 2U, and the server 10 can be installed by two levels of 1U server nodes. In fig. 1, the server 10 is in the form of 2U 4N. That is, the height of the server 10 is 2U and four server nodes are provided, but the height of the server 10 may be 1U or another height, and the number of server nodes provided in the server 10 is not limited thereto.
Generally, the height of the server 10 itself is limited, and the height of the server expansion card socket module 100 (fig. 2) for the expansion card 20 to be plugged into is also limited. The server expansion card socket module 100 of the present embodiment can be applied to a 1U server node (the height H1 (fig. 2) of the server expansion card socket module 100 is less than 1U), and can be horizontally inserted with two expansion cards 20 of PCI-E x16 on the premise that the height of the server node is 1U, so as to improve the performance of the server 10. In addition, since the height H1 of the server expansion card socket module 100 is less than 1U, it can be applied to a server 10 having a height of 1U or more. The server expansion card socket module 100 will be explained below.
FIG. 2 is a schematic diagram of two expansion cards inserted into an expansion card socket module of a server according to an embodiment of the invention. Fig. 3 is a schematic diagram of the server expansion card socket module of fig. 2. Fig. 4 is a schematic diagram of the server expansion card socket module of fig. 2 in which the second circuit board and the third circuit board are not yet plugged into the first circuit board. Fig. 5 is an exploded view of the server expansion card socket module of fig. 2. Fig. 6 is a schematic diagram of a first circuit board, a second circuit board and a third circuit board of the server expansion card socket module of fig. 2.
Referring to fig. 2 to fig. 6, the server expansion card socket module 100 of the present embodiment includes a first circuit board 110, a second circuit board 120 and a third circuit board 130. As shown in fig. 6, the first circuit board 110 includes two first slots 112 and a second slot 114. In the present embodiment, each first slot 112 is a PCI-E x8 interface, and each second slot 114 is a PCI-E x16 interface. Because of the two first slots 112 on the first circuit board 110 that interface to PCI-E x8, the two first slots 112 may together transmit a set of PCI-E x16 signals, plus the second slot 114 itself may transmit a set of PCI-E x16 signals. Thus, the first circuit board 110 may transmit two sets of PCI-E x16 signals.
It should be noted that, in the embodiment, the first circuit board 110 can use the two first slots 112 of the PCI-E x8 and the second slot 114 of the PCI-E x16 to transmit two sets of signals of the PCI-E x16, and the slots of the PCI-E x32 are not used, thereby effectively reducing the cost.
The first circuit board 110 further includes two connectors 116 for connecting the relay card, wherein one of the connectors 116 is electrically connected to the two first slots 112, and the other connector 116 is electrically connected to the second slot 114, so as to transmit two sets of signals of PCI-E x16 to the relay card.
In the embodiment, the two first slots 112 are located at two sides of the second slot 114, and the second slot 114 is located outside a connection line of the two first slots 112, so that the second circuit board 120 and the third circuit board 130 do not interfere with each other when being inserted. Of course, in other embodiments, the positional relationship between the first slots 112 and the second slots 114 is not limited thereto.
In addition, the second circuit board 120 includes two first plugging terminals 122 and a first expansion card slot 124. Each first plug 122 is a PCI-E x8 interface, and each first expansion card slot 124 is a PCI-E x16 interface. The two first plugging terminals 122 are electrically connected to the first expansion card slot 124. In the embodiment, the two first plugging ends 122 of the second circuit board 120 are detachably disposed in the two first slots 112 of the first circuit board 110, so that the first expansion card slot 124 of the second circuit board 120 is electrically connected to the two first slots 112 of the first circuit board 110.
The third circuit board 130 includes a second plug end 132 (shown in fig. 6 by a dotted line) and a second expansion card slot 134 electrically connected to each other. The second plug 132 and the second expansion card slot 134 are PCI-E x16 interfaces, the second plug 132 of the third circuit board 130 is detachably disposed in the second slot 114 of the first circuit board 110, so that the second expansion card slot 134 of the third circuit board 130 is electrically connected to the second slot 114 of the first circuit board 110.
In the embodiment, the second circuit board 120 and the third circuit board 130 are inserted side by side on the first circuit board 110, and the second circuit board 120 and the third circuit board 130 are at least partially staggered, so that the first expansion card slot 124 and the second expansion card slot 134 are vertically disposed above the first circuit board 110.
Specifically, in the present embodiment, the second circuit board 120 includes an opening 126, and the second expansion card slot 134 is disposed through the opening 126 of the second circuit board 120 and protrudes from the second circuit board 120. In the embodiment, the opening 126 of the second circuit board 120 is a closed opening 126, but in other embodiments, the opening 126 of the second circuit board 120 may also be a non-closed opening, such as a notch recessed in an edge of the second circuit board 120. In addition, in an embodiment, the second circuit board 120 may not have the opening 126, and the second circuit board 120 may be staggered or shifted to the second expresscard slot 134.
In addition, in the embodiment, the first expansion card slot 124 is located below the second expansion card slot 134, but not limited thereto, and in other embodiments, the first expansion card slot 124 may also be located above the second expansion card slot 134.
As shown in fig. 3, although the second circuit board 120 and the third circuit board 130 are located on different planes, in the embodiment, the height of the second expansion card slot 134 protruding from the second circuit board 120 is equal to the height of the first expansion card slot 124 protruding from the second circuit board 120, which is H2, so that the same situation as the first expansion card slot 124 and the second expansion card slot 134 on the same circuit board can be manufactured, so that an operator can insert and remove two expansion cards 20 more intuitively, and the length and width of the server expansion card socket module 100 in the space for accommodating the expansion cards 20 can be maintained at the length and width of one expansion card 20.
As shown in fig. 5, a height H3 of the second expresscard slot 134 protruding from the third circuit board 130 is greater than a height H2 of the first expresscard slot 124 protruding from the second circuit board 120. In addition, in other embodiments, the positions of the second circuit board 120 and the third circuit board 130 may be interchanged. Therefore, the height of the first expansion card slot 124 protruding from the second circuit board 120 may be larger than the height of the second expansion card slot 134 protruding from the third circuit board 130.
The two expansion card slots, the two corresponding circuits and the two sets of electronic components are difficult to configure on a single circuit board due to the size of the circuit board. In the server expansion card socket module 100 of the embodiment, the first expansion card slot 124 and the second expansion card slot 134 are respectively disposed on the second circuit board 120 and the third circuit board 130, and only one expansion card slot and the corresponding circuit and electronic components thereof need to be disposed on any one of the second circuit board 120 and the third circuit board 130.
Furthermore, the server expansion card socket module 100 is configured such that the first expansion card slot 124 and the second expansion card slot 134 are vertically disposed above the first circuit board 110 and are staggered from each other (for example, the second expansion card slot 134 passes through the opening 126 of the second circuit board 120 and is located above or below the first expansion card slot 124), so that two PCI-E x16 expansion cards 20 can be horizontally inserted on the premise that the height H1 (fig. 2) is less than 1U.
In addition, as shown in fig. 5, the server expansion card socket module 100 further includes a first bracket 140 and a second bracket 150. The first bracket 140 is disposed on the periphery of the first circuit board 110 and fixed to the first circuit board 110. In the present embodiment, the first bracket 140 is, for example, U-shaped, and surrounds three sides of the first circuit board 110, and exposes two connectors 116.
The second bracket 150 is disposed on the first bracket 140 and includes a first segment 151 parallel to the second circuit board 120 and the third circuit board 130 and a second segment 157 bent and connected to the first segment 151. The first segment 151 and the second segment 157 are L-shaped.
The second circuit board 120 and the third circuit board 130 are fixed to the first section 151 of the second bracket 150. Specifically, the server expansion card socket module 100 further includes a first locking member 160. The first section 151 of the second bracket 150 includes a first stud 152, and the second circuit board 120 includes a first through hole 128. The first locking member 160 is fixed to the first stud 152 through the first through hole 128, so that the second circuit board 120 is fixed to the first section 151 of the second bracket 150.
The server expansion card socket module 100 further includes a second locking member 162. The first section 151 of the second bracket 150 includes a second stud 153, and the third circuit board 130 includes a second through hole 136. The second locking member 162 is fixed to the second stud 153 through the second through hole 136, so that the third circuit board 130 is fixed to the first section 151 of the second bracket 150.
In the present embodiment, the third circuit board 130 is located between the second circuit board 120 and the first section 151 of the second bracket 150. Thus, the height of the second stud 153 is less than the height of the first stud 152. Further, the first section 151 of the second bracket 150 includes a support post 154. The height of the support post 154 is close to the height of the first stud 152. In the present embodiment, the third circuit board 130 has a smaller size and is offset to the supporting pillar 154, so that the supporting pillar 154 can pass over the third circuit board 130 and abut against the second circuit board 120. The support posts 154 can be used to reduce the possibility of board bending of the second circuit board 120.
In the present embodiment, the distance between the first expansion card slot 124 and the second section 157 of the second bracket 150 is equal to the distance between the second expansion card slot 134 and the second section 157 of the second bracket 150 (both are distances D indicated in fig. 3), so as to meet the specification of the expansion card 20.
In summary, the expansion card socket module of the server of the present invention can be applied to a 1U server node, and on the premise of this height, the expansion card socket module of the server can be inserted with two expansion cards of PCI-E x16 configured horizontally. Specifically, the server expansion card socket module is used for horizontally inserting two PCI-E x16 expansion cards by respectively arranging a first expansion card slot and a second expansion card slot of the PCI-E x16 on a second circuit board and a third circuit board, inserting the second circuit board and the third circuit board into the first circuit board, and enabling the first expansion card slot of the second circuit board and the second expansion card slot of the third circuit board to be vertically arranged above the first circuit board.
