Description

Technical Field

[0001] The present application relates to the technical field of computer equipment, and in particular to a connection module and a server. Background Art

[0002] The server includes a backplane and a mainboard, and a connector on the backplane is connected to a connection terminal on the mainboard. However, in the related art, the connector on the backplane is not easy to connect to the connection terminal on the mainboard, and the backplane and the mainboard are not easy to disassemble, which is not convenient for maintenance of the server. Summary of the invention

[0003] In view of this, the present application provides a connection module that can improve the problem of inconvenient maintenance of the server.

[0004] An embodiment of the present application provides a connection module applied to a server, wherein the server includes a mainboard, and the connection module includes a backplane, a first positioning member, a second positioning member, and a separator. The backplane is arranged on one side of the mainboard, the first positioning member is arranged on the backplane, and the second positioning member is arranged on the mainboard. The second positioning member is provided with a guide groove, and the guide groove is used to receive the first positioning member so that the second positioning member positions the first positioning member. The separator is rotatably arranged on the backplane, and the separator can rotate relative to the backplane between a first state and a second state. When the separator is in the first state, the first positioning member can be inserted into the guide groove to position the backplane to the mainboard. When the separator turns to the second state, the separator can drive the first positioning member to push the second positioning member so that the backplane moves away from the mainboard.

[0005] In the above embodiment, when the mainboard is connected to the backplane, the first positioning member is installed in the guide groove. The cooperation between the first positioning member and the guide groove can not only position the backplane on the mainboard to connect the backplane and the mainboard, but also the guide groove can provide a guiding function for the first positioning member, thereby improving the assembly accuracy of the backplane and the mainboard. When the separator rotates, it can drive the first positioning member to push the second positioning member, so that the second positioning member and the backplane move relative to each other, and the backplane moves away from the mainboard, so that the backplane and the mainboard can be separated from each other. The setting of the separator improves the convenience of disassembly of the backplane and the mainboard. When the mainboard or the backplane is damaged, the separator only needs to be rotated to move the backplane away from the mainboard, so that it is convenient to maintain the server after the mainboard and the backplane are disassembled.

[0006] In at least one embodiment, the first positioning member includes a first positioning column and a second positioning column. The first positioning column is provided with a guide hole along the axial direction. The guide hole passes through the opposite sides of the back plate. The second positioning column passes through the guide hole and can slide along the guide hole relative to the first positioning column. The separator is located on the side of the back plate facing away from the second positioning member. The end of the second positioning column close to the separator is the first end, and the end away from the separator is the second end. When the separator is in the first state, the first positioning column can be inserted into the guide groove, and the bottom surface of the guide groove can support the second end so that the first end extends out of the guide hole; when the separator rotates from the first state to the second state, the separator pushes the first end so that the second end extends out of the guide hole and lifts the second positioning member, thereby lifting the main board.

[0007] In the above embodiment, when the separator is in the first state, the first end extends out of the guide hole, and the second end contacts the bottom surface of the guide groove, that is, the second end is located in the guide groove, and the first positioning column is inserted into the guide groove, so that the first positioning member and the second positioning member are mutually positioned and connected. When the separator rotates from the first state to the second state, the separator pushes the first end outside the guide hole, the first end slides into the guide hole, and the second end extends from the guide hole and pushes the bottom surface of the guide groove, so that the second end lifts the second positioning member, and the second positioning member drives the main board to move away from the back board, so that the main board and the back board are separated from each other.

[0008] In at least one embodiment, the separating member is hinged to the first end portion, and when the separating member rotates, it can drive the second positioning column to slide along the guide hole.

[0009] In the above embodiment, the separating member is hinged to the first end portion, and when the separating member rotates, the first end portion and the separating member also rotate relative to each other, and the separating member drives the second positioning column to slide in the guide hole, so that the second positioning column pushes the second positioning member. In addition, the separating member is connected to the first end portion, which can reduce the situation where the separating member and the first end portion slip out of alignment when the separating member pushes the first end portion, resulting in unstable force on the first end portion.

[0010] In at least one embodiment, the second end portion is fixed to a groove bottom surface of the guide groove.

[0011] In the above embodiment, when the first positioning column enters the guide groove, the second positioning column can also enter the guide hole along the extension direction of the guide hole, and the cooperation between the second positioning column and the guide hole also provides a guide for the assembly of the back plate and the main board, thereby facilitating the connection between the back plate and the main board. The second end is fixed to the bottom of the guide groove, and when the separator pushes the first end, the second positioning column and the second positioning member can move together in a direction away from the back plate under the action of the separator, thereby separating the back plate and the main board from each other.

[0012] In at least one embodiment, the separator includes a pushing portion, a connecting portion and an operating portion, the connecting portion connects the operating portion and the pushing portion, and the connecting portion is rotatably connected to the back plate; when the separator rotates, the pushing portion can push the second positioning member through the first positioning member.

[0013] In the above embodiment, when the back plate and the main plate are separated, the operating part is rotated, and the operating part drives the pushing part to rotate through the connecting part. During the rotation of the pushing part, a force is applied to the first positioning member, so that the first positioning member pushes the second positioning member, thereby causing the second positioning member to move away from the back plate.

[0014] In at least one embodiment, the distance between the connecting portion and the pushing portion is smaller than the distance between the connecting portion and the operating portion.

[0015] In the above embodiment, when a force is applied to the end of the operating part away from the pushing part, the distance from the line of action of the force to the connecting part is greater than the distance between the connecting part and the pushing part. Therefore, the separation piece forms a force-saving lever, and the operating part and the part between the operating part and the connecting part are the power arm. The lever principle is utilized to improve the convenience of disassembly of the back panel and the main board. Compared with directly applying a force to the back panel to separate the main board from the back panel, this solution has a force-saving effect.

[0016] In at least one embodiment, the separator further includes a limiting portion, which is disposed on a side of the operating portion facing the back plate, and when the separator is in the first state, the limiting portion contacts the back plate.

[0017] In the above embodiment, when the separation member is in the first state, the limiting portion is located between the operating portion and the back plate, which makes it difficult for the operating portion to be completely fitted with the back plate, thereby facilitating the operating portion to be lifted relative to the back plate and facilitating the operating portion to drive the pushing portion to rotate.

[0018] In at least one embodiment, the pushing portion has an arc-shaped pushing surface, which is used to push the first end portion, and the pushing surface is in contact with the end surface of the first end portion.

[0019] In the above embodiment, when the push surface pushes the first end surface, the arc-shaped push surface can fit with the end surface of the first end portion, which makes the friction between the push surface and the end surface of the first end portion rolling friction, thereby reducing the wear on the push surface and the end surface of the first end portion caused by friction.

[0020] In at least one embodiment, a guide portion is provided at one end of the first positioning member facing the guide groove, and a cross-section of the guide portion gradually increases in a direction approaching the back plate.

[0021] In the above embodiment, the cross-section of the guide portion close to the mainboard is smaller than the cross-section of the guide portion close to the backboard. When the first positioning member enters the guide groove, the side of the guide portion close to the mainboard enters the guide groove first. The guide portion can guide the first positioning member into the guide groove, thereby facilitating the connection between the first positioning member and the second positioning member.

[0022] The embodiments of the present application also provide a server, which can improve the problem that the server is inconvenient to maintain.

[0023] A server provided in the present application includes a mainboard, a connection terminal and a connection module in any of the above embodiments, the second positioning member is arranged on the mainboard, the connection terminal is arranged on the mainboard and connected to the connector on the backplane.

[0024] In the above embodiment, when the connection terminal on the mainboard is connected to the connector on the backplane, the first positioning member is inserted into the guide groove so that the first positioning member is connected to the second positioning member, thereby realizing the connection between the mainboard and the backplane. When the connection terminal on the mainboard is separated from the connector on the backplane, the separation member is rotated so that the separation member pushes the first positioning member, and the first positioning member pushes the second positioning member away from the backplane, which is conducive to overcoming the plug-in and pull-out force between the connection terminal and the connector, so that the mainboard is separated from the backplane, thereby facilitating the maintenance of the server after the mainboard and the backplane are disassembled.

[0057] The following specific implementation methods will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0058] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0060] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0061] It should be noted that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary and should not constitute any limitation to the present application.

[0062] The server includes a backplane and a mainboard, and a connector on the backplane is connected to a connection terminal on the mainboard. However, in the related art, the connector on the backplane is not easy to connect to the connection terminal on the mainboard, and the backplane and the mainboard are not easy to disassemble, which is not convenient for maintenance of the server.

[0063] In view of this, an embodiment of the present application provides a connection module applied to a server, the server includes a mainboard, and the connection module includes a backplane, a first positioning member, a second positioning member and a separator. The backplane is arranged on one side of the mainboard, the first positioning member is arranged on the backplane, and the second positioning member is arranged on the mainboard. The second positioning member is provided with a guide groove, and the guide groove is used to receive the first positioning member so that the second positioning member positions the first positioning member. The separator is rotatably arranged on the backplane, and the separator can rotate relative to the backplane between a first state and a second state. When the separator is in the first state, the first positioning member can be inserted into the guide groove to position the backplane to the mainboard. When the separator turns to the second state, the separator can drive the first positioning member to push the second positioning member so that the backplane moves away from the mainboard.

[0064] In the above embodiment, when the mainboard is connected to the backplane, the first positioning member is installed in the guide groove. The cooperation between the first positioning member and the guide groove can not only position the backplane on the mainboard to connect the backplane and the mainboard, but also the guide groove can provide a guiding function for the first positioning member, thereby improving the assembly accuracy of the backplane and the mainboard. When the separator rotates, it can drive the first positioning member to push the second positioning member, so that the second positioning member and the backplane move relative to each other, and the backplane moves away from the mainboard, so that the backplane and the mainboard can be separated from each other. The setting of the separator improves the convenience of disassembly of the backplane and the mainboard. When the mainboard or the backplane is damaged, the separator only needs to be rotated to move the backplane away from the mainboard, so that it is convenient to maintain the server after the mainboard and the backplane are disassembled.

[0065] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0066] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a server 100, which includes a mainboard 11, a connection terminal 12 and a connection module 200, wherein the connection terminal 12 is arranged on the mainboard 11, and the connection module 200 includes a connector 21, and the connection terminal 12 is connected to the connector 21.

[0067] In some embodiments, the connection terminal 12 is located on the side of the mainboard 11 facing the backplane 22, and the connector 21 is located on the side of the backplane 22 facing the mainboard 11. When the mainboard 11 and the backplane 22 are assembled, the connector 21 is aligned with and connected to the connection terminal 12.

[0068] See also Figures 1 to 3 In some embodiments, the connection module 200 further includes a back plate 22, a first positioning member 23 and a second positioning member 24. The back plate 22 is disposed on one side of the main board 11, the first positioning member 23 is disposed on the back plate 22, and the second positioning member 24 is disposed on the main board 11. The second positioning member 24 is provided with a guide groove 241, and the guide groove 241 is used to receive the first positioning member 23 so that the second positioning member 24 positions the first positioning member 23. When the main board 11 is connected to the back plate 22, the first positioning member 23 is installed in the guide groove 241. The cooperation between the first positioning member 23 and the guide groove 241 can not only position the back plate 22 on the main board 11 to connect the back plate 22 and the main board 11, but also the guide groove 241 can provide a guiding function for the first positioning member 23, thereby improving the assembly accuracy of the back plate 22 and the main board 11.

[0069] See also Figures 3 to 5 In some embodiments, a guide portion 231 is provided at one end of the first positioning member 23 facing the guide groove 241, and the cross section of the guide portion 231 gradually increases along the direction close to the back plate 22. The direction of the cross section is perpendicular to the axial direction of the first positioning member 23, and the first positioning member 23 can be installed in the guide groove 241 along the axial direction of the first positioning member 23. In the above embodiment, the cross section of the guide portion 231 close to the main board 11 is smaller than the cross section of the guide portion 231 close to the back plate 22. When the first positioning member 23 enters the guide groove 241, the side of the guide portion 231 close to the main board 11 enters the guide groove 241 first, and the guide portion 231 can guide the first positioning member 23 to enter the guide groove 241, thereby facilitating the connection between the first positioning member 23 and the second positioning member 24.

[0070] See also Figures 3 to 5 In some embodiments, the connection module 200 further includes a separator 25 , which is rotatably disposed on the back plate 22 , and the separator 25 can rotate relative to the back plate 22 between a first state and a second state. Figure 3 The separating member 25 is in a first state, Figure 4 The separator 25 is in the second state. When the separator 25 is in the first state, the first positioning member 23 can be inserted into the guide groove 241 to position the back plate 22 to the main board 11. When the separator 25 turns to the second state, the separator 25 can drive the first positioning member 23 to push the second positioning member 24, so that the back plate 22 moves away from the main board 11.

[0071] When the separating member 25 rotates, it can drive the first positioning member 23 to push the second positioning member 24, so that the second positioning member 24 and the back plate 22 move relative to each other, and the back plate 22 moves away from the main board 11, so that the back plate 22 and the main board 11 can be separated from each other. The setting of the separating member 25 improves the convenience of disassembling the back plate 22 and the main board 11. When the main board 11 or the back plate 22 is damaged, the back plate 22 can be moved away from the main board 11 by simply rotating the separating member 25, so that it is convenient to maintain the server 100 after the main board 11 and the back plate 22 are disassembled.

[0072] See also Figures 3 to 5 In some embodiments, the separator 25 is located on the side of the back plate 22 facing away from the second positioning member 24. The first positioning member 23 includes a first positioning column 232 and a second positioning column 233. The first positioning column 232 is provided with a guide hole 2321 along the axial direction. The guide hole 2321 passes through the opposite sides of the back plate 22. The second positioning column 233 passes through the guide hole 2321 and can slide along the guide hole 2321 relative to the first positioning column 232. The end of the second positioning column 233 close to the separator 25 is the first end 2331, and the end away from the separator 25 is the second end 2332. When the separator 25 is in the first state, the first positioning column 232 can be inserted into the guide groove 241, and the bottom surface of the guide groove 241 can support the second end 2332, so that the first end 2331 extends out of the guide hole 2321. When the separating member 25 rotates from the first state to the second state, the separating member 25 pushes the first end portion 2331 , so that the second end portion 2332 extends out from the guide hole 2321 and lifts up the second positioning member 24 , thereby lifting up the main board 11 .

[0073] When the separating member 25 is in the first state, the first end portion 2331 extends out of the guide hole 2321, and the second end portion 2332 contacts the bottom surface of the guide groove 241, that is, the second end portion 2332 is located in the guide groove 241. At this time, the first positioning column 232 is inserted into the guide groove 241, so that the first positioning member 23 and the second positioning member 24 are mutually positioned and connected. Figure 3When the separating member 25 rotates from the first state to the second state, the separating member 25 pushes the first end portion 2331 outside the guide hole 2321, the first end portion 2331 slides into the guide hole 2321, and the second end portion 2332 extends from the guide hole 2321 and pushes the bottom surface of the guide groove 241, so that the second end portion 2332 lifts the second positioning member 24, and the second positioning member 24 drives the main board 11 to move away from the back plate 22, so that the main board 11 and the back plate 22 are separated from each other, as shown in FIG. Figure 4 and Figure 5 shown.

[0074] See also Figures 3 to 5 In some embodiments, along the axial direction of the first positioning member 23, the length of the first positioning column 232 is less than the length of the second positioning column 233. The first positioning column 232 includes a mounting portion 2322 and a positioning portion 2323 connected to each other, and the back plate 22 is provided with a mounting hole 221. The mounting portion 2322 and the positioning portion 2323 are generally cylindrical, the diameter of the mounting portion 2322 is greater than the inner diameter of the mounting hole 221, the mounting portion 2322 is located on the side of the back plate 22 facing the separator 25, a part of the positioning portion 2323 is located in the mounting hole 221, and the other part is located on the side of the back plate 22 away from the separator 25 and is used to be inserted into the guide groove 241, that is, the other part of the positioning portion 2323 is located on the side of the back plate 22 facing the second positioning member 24. The guide hole 2321 passes through the end surface of the mounting portion 2322 facing the separator 25 and the end surface of the positioning portion 2323 facing the bottom surface of the guide groove 241.

[0075] When the positioning portion 2323 of the first positioning column 232 is pulled out from the guide groove 241, the positioning portion 2323 is subjected to the friction force of the inner wall of the guide groove 241 and has a tendency to move toward the groove bottom surface of the guide groove 241. Since the diameter of the mounting portion 2322 is larger than the inner diameter of the mounting hole 221, the mounting portion 2322 is not easy to enter the mounting hole 221, thereby limiting the movement of the positioning portion 2323 toward the groove bottom surface of the guide groove 241, so as to improve the stability of the connection between the first positioning column 232 and the back plate 22, so that when the back plate 22 is separated from the main board 11, the first positioning column 232 is not easy to be separated from the back plate 22.

[0076] See also Figures 3 to 5In some embodiments, the outer wall of the second positioning column 233 can contact the inner wall of the guide hole 2321, and there is friction between the outer wall of the second positioning column 233 and the inner wall of the guide hole 2321. The friction is sufficient to keep the second positioning column 233 relatively still with the first positioning column 232 without being subjected to other forces. This enables the second positioning column 233 to slide in the guide hole 2321 and push the second positioning member 24 when the separation member 25 rotates relative to the back plate 22 and pushes the second positioning column 233; when the separation member 25 is stationary relative to the back plate 22, the second positioning column 233 stays in the guide hole 2321. In the above embodiment, when the first positioning member 23 is separated from the second positioning member 24, the friction between the second positioning column 233 and the first positioning column 232 can make the first positioning column 232 and the second positioning column 233 difficult to separate, thereby making the second positioning column 233 difficult to lose.

[0077] See also Figures 3 to 5 In some embodiments, one end of the first positioning column 232 facing the guide groove 241 is the guide portion 231. When the first positioning member 23 is connected to the second positioning member 24, the second end portion 2332 is located in the guide hole 2321 and is flush with the end surface of the guide portion 231, so that the end surface of the second end portion 2332 facing the guide groove 241 and the end surface of the first positioning column 232 facing the guide groove 241 can simultaneously contact the bottom surface of the guide groove 241, thereby increasing the length of the first positioning member 23 entering the guide groove 241 and improving the connection stability of the first positioning member 23 and the second positioning member 24.

[0078] In one embodiment, the separator 25 is hinged to the first end 2331, and when the separator 25 rotates, it can drive the second positioning column 233 to slide along the guide hole 2321. When the separator 25 rotates, the first end 2331 and the separator 25 also rotate relatively, and the separator 25 drives the second positioning column 233 to slide in the guide hole 2321, so that the second positioning column 233 pushes the second positioning member 24. In addition, the separator 25 is connected to the first end 2331, which can reduce the situation that the first end 2331 is unstable due to the slippage and misalignment of the separator 25 and the first end 2331 when the separator 25 pushes the first end 2331.

[0079] See also Figure 5In one embodiment, the second end portion 2332 is fixed to the bottom surface of the guide groove 241. When the first positioning column 232 enters the guide groove 241, the second positioning column 233 can also enter the guide hole 2321 along the extension direction of the guide hole 2321. The cooperation between the second positioning column 233 and the guide hole 2321 also provides a guide for the assembly of the back plate 22 and the main board 11, thereby facilitating the connection between the back plate 22 and the main board 11. The second end portion 2332 is fixed to the bottom of the guide groove 241. When the separator 25 pushes the first end portion 2331, the second positioning column 233 and the second positioning member 24 can move together in a direction away from the back plate 22 under the action of the separator 25, thereby separating the back plate 22 and the main board 11 from each other.

[0080] In some embodiments, the first positioning column 232 is made of rubber, and the second positioning column 233 and the second positioning member 24 are made of metal or plastic. The rubber material has a large friction force, which can make the second positioning column 233 and the second positioning member 24 stably connected to the first positioning column 232. It can be understood that in other embodiments, the first positioning member 23 and the second positioning member 24 can both be made of rubber, metal or plastic.

[0081] See also Figure 3 , Figure 4 and Figure 6 In some embodiments, the separator 25 includes a pushing portion 251, a connecting portion 252 and an operating portion 253, the connecting portion 252 connects the operating portion 253 and the pushing portion 251, and the connecting portion 252 is rotatably connected to the back plate 22; when the separator 25 rotates, the pushing portion 251 can push the second positioning member 24 through the first positioning member 23.

[0082] When the back plate 22 and the main plate 11 are separated, the operating portion 253 is rotated, and the operating portion 253 drives the pushing portion 251 to rotate through the connecting portion 252. During the rotation of the pushing portion 251, a force is applied to the first positioning member 23, so that the first positioning member 23 pushes the second positioning member 24, thereby causing the second positioning member 24 to move away from the back plate 22.

[0083] In one embodiment, the distance between the connecting portion 252 and the pushing portion 251 is smaller than the distance between the connecting portion 252 and the operating portion 253 .

[0084] When a force is applied to the end of the operating part 253 away from the pushing part 251, the distance from the line of action of the force to the connecting part 252 is greater than the distance between the connecting part 252 and the pushing part 251. Therefore, the separating piece 25 forms a force-saving lever. The operating part 253 and the part between the operating part 253 and the connecting part 252 are power arms. By utilizing the principle of lever, the convenience of disassembling the back panel 22 and the main board 11 is improved. Compared with directly applying a force to the back panel 22 to separate the main board 11 from the back panel 22, this solution has a force-saving effect.

[0085] See also Figure 3 , Figure 4 and Figure 6 In one embodiment, the separator 25 further includes a limiting portion 254 , which is disposed on a side of the operating portion 253 facing the back plate 22 . When the separator 25 is in the first state, the limiting portion 254 contacts the back plate 22 .

[0086] When the separator 25 is in the first state, the limiting portion 254 is located between the operating portion 253 and the back plate 22, which makes it difficult for the operating portion 253 to completely fit with the back plate 22, thereby facilitating the operating portion 253 to be lifted relative to the back plate 22 and facilitating driving the pushing portion 251 to rotate through the operating portion 253.

[0087] In some embodiments, the separator 25 is generally in the shape of a long rod. When the separator 25 is in the first state, the separator 25 is generally parallel to the back plate 22. During the process of the separator 25 rotating from the first state to the second state, an angle α is formed between the separator 25 and the back plate 22. The range of the angle α is 0 degrees <α≤45 degrees. In the above embodiments, the setting of the angle α can not only enable the separator 25 to rotate to facilitate the separation of the main board 11 and the back plate 22, but also reduce the space occupied by the separator 25 when rotating.

[0088] See also Figure 3 , Figure 4 and Figure 6 In some embodiments, the pushing portion 251 has an arcuate pushing surface 2511, which is used to push the first end portion 2331, and the pushing surface 2511 fits with the end surface of the first end portion 2331. When the pushing surface 2511 pushes the first end surface, the arcuate pushing surface 2511 can fit with the end surface of the first end portion 2331, so that the friction between the pushing surface 2511 and the end surface of the first end portion 2331 is rolling friction, thereby reducing the wear of the pushing surface 2511 and the end surface of the first end portion 2331 caused by friction.

[0089] In some embodiments, the end surface of the first end portion 2331 is an arc surface that can fit with the push surface 2511. When the push portion 251 rotates, the push surface 2511 rolls relative to the end surface of the first end portion 2331, thereby reducing friction and wear between the push surface 2511 and the end surface of the first end portion 2331.

[0090] See also Figure 1 and Figure 2 In some embodiments, a plurality of connection terminals 12 are provided on the mainboard 11, and a plurality of connectors 21 are provided on the backboard 22, and the plurality of connection terminals 12 correspond to and are connected to the plurality of connectors 21 one by one. The connection module 200 includes a plurality of separation members 25, a first positioning member 23, and a second positioning member 24. Each separation member 25 cooperates with one of the first positioning members 23 and one of the second positioning members 24 to position and connect the mainboard 11 and the backboard 22. The plurality of separation members 25 can rotate together to separate the mainboard 11 from the backboard 22.

[0091] When the connection terminal 12 on the mainboard 11 is connected to the connector 21 on the backplane 22, the first positioning member 23 is inserted into the guide groove 241 so that the first positioning member 23 is connected to the second positioning member 24, thereby realizing the connection between the mainboard 11 and the backplane 22. When the connection terminal 12 on the mainboard 11 is separated from the connector 21 on the backplane 22, the separation member 25 is rotated so that the separation member 25 pushes the first positioning member 23, and the first positioning member 23 pushes the second positioning member 24 away from the backplane 22, thereby facilitating overcoming the plug-in and pull-out force between the connection terminal 12 and the connector 21, so that the mainboard 11 is separated from the backplane 22, thereby facilitating the maintenance of the server 100 after the mainboard 11 and the backplane 22 are disassembled.

[0092] In addition, those skilled in the art may also make other changes in the present application. Of course, these changes made based on the present application should be included in the scope disclosed in the present application.
