In the related art, the PCIE expansion card needs to be mutually inserted with the main board to establish electrical connection, and the scheme adopted by the insertion between the PCIE expansion card and the main board is that a golden finger at the PCIE expansion card end is aligned with a main board slot and then is inserted downwards perpendicular to the main board so that the golden finger is inserted into the main board slot, and then the PCIE expansion card and the main board are electrically connected. However, the inserting mode has the following defects that the inserting force of the golden finger is large, the golden finger is difficult to insert in place at one time, larger force is needed, the damage probability to the PCIE expansion card is increased, when the PCIE expansion card needs to be pulled out, no good force application point exists, the PCIE expansion card is difficult to pull out from the main board, and therefore the PCIE expansion card is difficult to assemble and disassemble.

In addition, as the cooling effect of the liquid cooling mode is stronger than that of the air cooling mode, in the related art, the PCIE expansion card can dissipate heat in a liquid cooling mode, and the liquid cooling plug at the PCIE expansion card end is mainly subjected to blind insertion currently, wherein the blind insertion scheme mainly comprises the steps of aligning a golden finger at the PCIE expansion card end with a main board slot, aligning a blind insertion head at the PCIE expansion card end with a blind insertion head at the splitter end, and then inserting the blind insertion head at the downward direction perpendicular to the main board. However, the blind plugging scheme has the following defects in practical application that firstly, the blind plug is large in plugging force, the blind plug is difficult to plug in place at one time, larger force is needed, the damage probability to the PCIE expansion card is increased, and when the PCIE expansion card needs to be pulled out, no good force application point exists, so that the PCIE expansion card is difficult to pull out. Secondly, because the PCIE expansion card is difficult to insert smoothly due to large insertion force, the PCIE expansion card needs to be pressed downwards by adjusting the force application point for multiple times, so that the leakage probability of the blind plug position can be increased, and the server is damaged.

It should be noted that, the side plates 120 may be disposed on two opposite sides of the bottom plate 110, and the side plates 120 disposed on two opposite sides of the bottom plate 110 may be provided with the board inserting assembly, so that the two opposite sides of the expansion card assembly 300 may be simultaneously biased downward, or the two opposite sides of the expansion card assembly 300 may be simultaneously biased upward, so that the stress of the expansion card assembly 300 is more uniform, and further, the expansion card assembly 300 is prevented from being inclined relative to the other side due to uneven stress in the process of inserting and extracting the expansion card assembly 300.

Specifically, the plug assembly 400 may include a connecting piece 410 and an executing piece 420, where the connecting piece 410 is used to connect the bending portion 122 and the executing piece 420, so that the executing piece 420 is rotatably disposed at the bending portion 122 and can rotate relative to the bending portion 122, so that when the expansion card assembly 300 and the motherboard assembly 200 need to be plugged, the executing piece 420 can be rotated, and the executing piece 421 can further drive the expansion card assembly 300 to move towards the bottom plate 110, so that the expansion card assembly 300 is plugged with the motherboard assembly 200 smoothly. Or when the expansion card assembly 300 and the main board assembly 200 are required to be disconnected from the socket, the executing piece 420 can be rotated, so that the executing part 421 drives the expansion card assembly 300 to move away from the bottom board 110, and the expansion card assembly 300 is smoothly disconnected from the main board assembly 200.

Compared with the plugging mode in the prior art, the server of the embodiment of the application plugs the expansion card assembly 300 by the execution part 420, when the execution part 421 drives the expansion card assembly 300 to move, the contact position between the execution part 421 and the expansion card assembly 300 is basically fixed and cannot be changed due to the change of operators, so that the plug assembly 400 has a fixed force point, the expansion card assembly 300 has a fixed force point, the plug process of the expansion card assembly 300 can be standardized, and the plug efficiency of the expansion card assembly 300 is improved.

Compared with the method that the expansion card assembly 300 is directly plugged and pulled by hand, the expansion card assembly 300 is pressed downwards by the aid of the executing piece 420, or the expansion card assembly 300 is pushed upwards by the aid of the executing piece 420, so that partial force can be saved by utilizing the lever principle, and further the expansion card assembly 300 is plugged and pulled more labor-saving.

The server provided by the embodiment of the application comprises a chassis 100, a main board assembly 200, an expansion card assembly 300 and a plug assembly 400, wherein the chassis 100 comprises a bottom board 110 and a side board 120, the side board 120 comprises an avoidance gap 1221, the plug assembly 400 comprises a connecting piece 410 and an executing piece 420, and the executing piece 420 comprises an executing part 421. The side plate body 121 is used for connecting the bottom plate 110 and installing the plug assembly 400, the avoidance notch 1221 is used for avoiding the execution part 421 so as to avoid interference with the bending part 122 when the execution part 421 rotates, the connecting piece 410 is used for connecting the bending part 122 and the execution piece 420 so that the execution piece 420 rotates to be arranged at the bending part 122, the execution part 421 is used for applying force to the expansion card assembly 300, and then the execution part 421 drives the expansion card assembly 300 to move towards the bottom plate 110 when rotating so as to enable the expansion card assembly 300 to be inserted into the main plate assembly 200, or the execution part 421 rotates so as to drive the expansion card assembly 300 to move away from the bottom plate 110 so as to enable the expansion card assembly 300 to be separated from the main plate assembly 200.

Referring to fig. 2,5, 9, and 10, in some embodiments, the expansion card assembly 300 includes an expansion card 310 and an ear plate 320 that are connected to each other, the ear plate 320 has a first escape hole 321, and the actuator 421 has a second escape hole 4211.

It can be appreciated that the ear plate 320 is mainly used for mounting the expansion card 310 on the side plate 120, and further the expansion card assembly 300 is integrally and fixedly mounted on the chassis 100 through the ear plate 320, so as to prevent the expansion card assembly 300 from moving relative to the chassis 100 when the server works.

Specifically, the ear plate 320, the executing portion 421 and the side plate 120 may be screwed together by the fastening member 430, that is, the fastening member 430 sequentially passes through the second avoiding hole 4211 of the executing portion 421 and the first avoiding hole 321 of the ear plate 320, and then the external thread of the fastening member 430 is matched with the internal thread of the connecting hole 1222, and the three parts of the ear plate 320, the executing portion 421 and the side plate 120 are relatively fixed by the stop function of the head of the fastening member 430, so that the expansion card 310 may be firmly installed on the chassis 100, and when the expansion card 310 needs to be pulled out, the fastening member 430 may be loosened, and the executing portion 421 is rotated, so that the executing portion 421 drives the ear plate 320 to move relative to the bottom plate 110, and further drives the expansion card 310 to be plugged into or out of plugging with the main board assembly 200.

In the above arrangement, the stress point of the expansion card assembly 300 is located at the ear plate 320, the structural strength of the ear plate 320 is high, the ear plate 320 is not easy to be damaged even if repeatedly stressed, more electronic elements are arranged in the expansion card 310, and the structural strength is low, so that the expansion card 310 is prevented from being damaged due to direct force applied to the expansion card 310.

Referring to fig. 5, 9, and 10, in one possible implementation, the plug assembly 400 further includes an elastic member 440, the elastic member 440 is sleeved on the fastener 430, and the elastic member 440 is elastically abutted between the head of the fastener 430 and the ear plate 320.

In this way, the elastic member 440 can provide elastic force to the ear plate 320, so as to press the ear plate 320 against the side plate 120, thereby firmly mounting the expansion card assembly 300 on the side plate 120.

Referring to fig. 2 and 3, in some embodiments, the server provided by the embodiment of the application further includes a liquid cooling assembly 500, the liquid cooling assembly 500 is connected to the chassis 100, the expansion card 310 has a first plugging portion 311 and a second plugging portion 312, the motherboard assembly 200 has a third plugging portion 210, the liquid cooling assembly 500 has a fourth plugging portion 510, the first plugging portion 311 is plugged into the third plugging portion 210 so as to electrically connect the expansion card 310 and the motherboard assembly 200, the second plugging portion 312 is plugged into the fourth plugging portion 510 so as to mechanically connect the expansion card 310 and the liquid cooling assembly 500, and the plugging direction of the first plugging portion 311 and the second plugging portion 312 are consistent.

It can be appreciated that when the expansion card assembly 300 performs heat dissipation in a liquid cooling manner, the liquid cooling assembly 500 needs to be disposed in the chassis 100, the liquid cooling assembly 500 needs to be provided with a cooling medium inlet and outlet, that is, the fourth plugging portion 510, and the expansion card 310 also needs to be provided with a cooling medium inlet and outlet, that is, the second plugging portion 312, and after the second plugging portion 312 and the fourth plugging portion 510 are plugged with each other, the cooling medium can flow between the liquid cooling assembly 500 and the expansion card 310, and heat of the expansion card 310 is further taken away by the cooling medium.

In the above arrangement, the plugging directions of the first plugging portion 311 and the second plugging portion 312 are consistent, that is, when the expansion card 310 is plugged with the motherboard assembly 200, the expansion card 310 can be plugged with the liquid cooling assembly 500, and under the assistance of the plugging assembly 400, the plugging efficiency of the expansion card 310 can be improved by improving the convenience and saving labor when the second plugging portion 312 and the fourth plugging portion 510 are plugged, and the repeated plugging caused by inaccurate plugging positions can be prevented, so that one or both of the second plugging portion 312 and the fourth plugging portion 510 leak liquid.

Referring to fig. 5, 9, and 10, in the specific implementation, the actuator 421 includes a first actuator 4212 and a second actuator 4213, an angle is formed between an extending direction of the first actuator 4212 and an extending direction of the second actuator 4213, and the second escape hole 4211 is located in the first actuator 4212.

When the actuating portion 421 rotates relative to the avoidance gap 1221, because an included angle is formed between the first actuating portion 4212 and the second actuating portion 4213, the first actuating portion 4212 and the second actuating portion 4213 have different positions relative to the ear plate 320, one of the first actuating portion 4212 and the second actuating portion 4213 may abut against the ear plate 320, and the other of the first actuating portion 4212 and the second actuating portion 4213 may be disengaged from the ear plate 320, so as to drive the ear plate 320 to move towards the bottom plate 110 or move away from the bottom plate 110.

For example, when the expansion card 310 needs to be plugged with the motherboard assembly 200, the first executing portion 4212 is rotated to abut against the ear plate 320, so as to press the ear plate 320 downwards, and further drive the expansion card 310 to move towards the motherboard 110, so that the expansion card 310 is plugged with the motherboard assembly 200, and when the expansion card 310 needs to be disconnected from the motherboard assembly 200, the second executing portion 4213 is rotated to abut against the ear plate 320, so as to push the ear plate 320 downwards, and further drive the expansion card 310 to move away from the motherboard 110, so that the expansion card 310 is disconnected from the motherboard assembly 200.

Referring to fig. 5 and 9 to 11, in some embodiments, a surface of the first actuator 4212 facing the second actuator 4213 has a first contact surface 4212a, and a surface of the second actuator 4213 facing the first actuator 4212 has a second contact surface 4213a. The first abutment surface 4212a is configured to abut a surface of the ear plate 320 facing away from the base plate 110 when the expansion card 310 is installed to drive the expansion card 310 to move toward the base plate 110. The second abutment surface 4213a is configured to abut a surface of the ear plate 320 facing the base plate 110 to drive the expansion card 310 to move away from the base plate 110 when the expansion card 310 is detached.

In this way, the first abutting surface 4212a of the first executing portion 4212 may abut against a surface of the ear plate 320 facing away from the bottom plate 110, when the expansion card 310 is required to be plugged into the main board assembly 200, the ear plate 320 is pressed downward, and the second abutting surface 4213a of the second executing portion 4213 may abut against a surface of the ear plate 320 facing the bottom plate 110, so as to push up the ear plate 320, so that the executing portion 421 can effectively assist an operator in the inserting and extracting process of the expansion card 310, thereby improving the inserting and extracting efficiency of the expansion card 310 and avoiding leakage of the expansion card 310 or the liquid cooling assembly 500.

In some embodiments, the included angle is greater than or equal to 25 ° and less than or equal to 50 °. It can be appreciated that if the included angle between the first executing portion 4212 and the second executing portion 4213 is too small, the expansion card 310 is not yet fully inserted into the motherboard assembly 200, the first executing portion 4212 cannot continuously apply force to the ear plate 320 or is not yet fully pulled out from the motherboard assembly 200, the second executing portion 4213 cannot continuously apply force to the ear plate 320, so that the convenience of inserting and pulling the assembly 400 is reduced, and if the included angle between the first executing portion 4212 and the second executing portion 4213 is too large, a larger angle is required to rotate to enable the first executing portion 4212 or the second executing portion 4213 to abut against the ear plate 320, so that the operation difficulty of an operator is increased.

Therefore, it is a preferable range to set the angle between the first actuator 4212 and the second actuator 4213 to be 25 ° to 50 °. Illustratively, the included angle may be any one of 25 °, 30 °, 45 °,50 °, or within any two ranges of values.
