Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electronic devices, and in particular, to a computing device. Background Art

[0002] With the rise of big data, cloud computing, and artificial intelligence (AI), the requirements for the communication quality of computing devices are becoming increasingly higher.

[0003] The computing device includes a circuit board that needs to be electrically connected. Taking two circuit boards that are electrically connected to each other as an example, a first connector is provided on one of the circuit boards, and a second connector is provided on the other circuit board. The two circuit boards can be electrically connected by plugging the first connector into the second connector. There is a gap between the first connector and the second connector at the plug-in point. The larger the gap value, the greater the contact impedance between the first connector and the second connector, and the impedance will interfere with signal transmission. Therefore, the gap will reduce the quality of signal transmission between the circuit board and the backplane. In the related art, an adapter board can be provided in the computing device. By connecting the circuit board with the adapter board, a force can be applied to the circuit board to reduce the gap between the first connector and the second connector.

[0004] However, the adapter plate cannot effectively reduce the gap between the first connector and the second connector, and the provision of the adapter plate makes the structure of the computing device more complicated. Utility Model Content

[0005] An embodiment of the present application provides a computing device, in which the gap between connectors that are plugged into each other in the computing device is small and the structure of the computing device is relatively simple.

[0006] In a first aspect, an embodiment of the present application provides a computing device, comprising: a first circuit board, a second circuit board, a first connector, a second connector, a connecting assembly and a guide sleeve, wherein the first connector is located on the first circuit board, the second connector is located on the second circuit board, and the first connector is plugged into the second connector; the guide sleeve is located on the first circuit board; the connecting assembly comprises a first connecting portion and a second connecting portion, the first connecting portion is located on the guide sleeve, the second connecting portion is located on the second circuit board, and the first connecting portion is connected to the second connecting portion to reduce a gap between the first connector and the second connector.

[0007] The computing device provided by the embodiment of the present application is configured such that the first connecting portion of the connecting component is located on the guide sleeve, the guide sleeve is located on the first circuit board, and the second connecting portion is located on the second circuit board. The first connecting portion is connected to the second connecting portion so that there is a pulling force between the first connecting portion on the first circuit board and the second connecting portion on the second circuit board. The pulling force between the first connecting portion and the second connecting portion can make the first board edge and the second board edge close to each other, thereby reducing the gap between the first connector and the second connector. In addition, by arranging the first connecting portion on the guide sleeve and the second connecting portion on the second circuit board, there is no need to additionally arrange other structural parts in the computing device to reduce the gap between the first connector and the second connector, thereby simplifying the internal structure of the computing device.

[0008] In a possible implementation, in the computing device provided by the embodiment of the present application, the guide sleeve is arranged near the first connector; the second circuit board has a guide pin, the guide pin is arranged near the second connector, the guide sleeve has a limiting hole, and the guide pin is inserted in the limiting hole, so that the first connector and the second connector are aligned when plugged in. The spacing between the guide sleeve and the first connector is small, and the spacing between the corresponding guide pin and the second connector is also small. Therefore, when the plugging of the first connector and the second connector is limited by the guide sleeve and the guide pin, the tolerance caused by the spacing can be reduced, so that the first connector and the second connector are better aligned.

When the screw is screwed into the threaded hole, the first board edge and the second board edge are brought closer to each other, thereby reducing the gap between the first connector and the second connector.

[0010] In a possible implementation, in the computing device provided by the embodiment of the present application, the projection of the threaded hole on the first circuit board overlaps with the projection of the position-limiting hole on the first circuit board; the connection assembly further includes a first support member, the first support member has a first through hole, the first through hole is aligned with the threaded hole, and the second connection portion is inserted in the first through hole so that the screw is threadedly connected to the threaded hole. The threaded hole and the position-limiting hole are arranged side by side along the third direction, and the threaded hole is arranged on the guide sleeve without increasing the size of the guide sleeve along the first direction or the second direction, thereby not increasing the space occupied by the guide sleeve on the board surface of the first circuit board, so that there is more space on the first circuit board to arrange other electronic components, so as to make full use of the space on the first circuit board.

By connecting the threaded hole with the limiting hole, the threaded hole is coaxially arranged with the limiting hole, and the second through hole is arranged in the guide pin, the space occupied by the guide sleeve on the first circuit board can be further reduced, so that there is more space on the first circuit board to arrange other electronic components, so as to make full use of the space on the first circuit board.

[0012] In a possible implementation, the computing device provided in the embodiment of the present application, the first connection part is a slot provided on the guide sleeve, the second connection part is a connecting rod, the connecting rod has a buckle, and the buckle is engaged with the slot. The processing method of the slot is relatively simple and the buckle is easy to operate when engaged with the slot.

[0013] In a possible implementation, the computing device provided in the embodiment of the present application, the second connection part further includes an elastic member, one end of the elastic member is connected to the connecting rod, and the other end of the elastic member is connected to the buckle; when the elastic member is in a naturally extended state, the buckle extends from the outer wall of the connecting rod; when the elastic member is in a compressed state, the buckle and the outer wall of the connecting rod remain flush. By connecting the buckle and the connecting rod with the elastic member, interference between the guide sleeve and the buckle can be avoided, making the buckle-slot connection process more convenient.

The abutment between the wrench and the housing can maintain a stable tension between the buckle and the slot, so that the first board edge and the second board edge are close to each other, and the gap between the first connector and the second connector can be reduced.

[0016] In a possible implementation, in the computing device provided by the embodiment of the present application, the wrench is rotatably connected to the connecting rod. The rotatable connection between the wrench and the connecting rod can facilitate the wrench to extend out of the housing so that the wrench can abut against the housing.

[0062] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0063] With the rise of big data, cloud computing, and artificial intelligence (AI), the requirements for the communication quality of computing devices are becoming increasingly higher.

[0064] The computing device includes two or more circuit boards that need to be electrically connected. Take two circuit boards that are electrically connected to each other as an example. A first connector is provided on one circuit board, and a second connector is provided on the other circuit board. The two circuit boards can be electrically connected by plugging the first connector into the second connector. There is a gap between the first connector and the second connector at the plug-in point. The larger the gap value, the greater the contact impedance between the first connector and the second connector, and the impedance will interfere with signal transmission. Therefore, the gap will reduce the quality of signal transmission between the circuit board and the backplane.

[0065] In the related art, an adapter board can be provided in a computing device. By connecting two circuit boards to the adapter board, a force can be applied to the circuit boards so that the two electrically connected circuit boards tend to move toward each other to reduce the gap between the first connector and the second connector. However, providing an adapter board will introduce additional components. Both of the electrically connected circuit boards need to cooperate with the adapter board. Therefore, there is a matching gap between the first connector and the adapter board, and there is a matching gap between the second connector and the adapter board. The existence of the matching gap makes the adapter board limited in its effect on reducing the gap between the first connector and the second connector. The provision of the adapter board will also make the structure of the computing device more complicated. In addition, in some computing devices where there is no adapter board, there is no effective measure to reduce the gap between the first connector and the second connector.

[0066] Based on this, an embodiment of the present application provides a computing device, in which the gap value between connectors that are plugged into each other in the computing device is small and the structure in the computing device is relatively simple.

[0068] See also Figure 1 and Figure 2 As shown, the computing device 100 includes a first circuit board 110, a second circuit board 120, a connection assembly 130, a connector assembly 140 and a guide sleeve 150; the connector assembly 140 includes a first connector 141 and a second connector 142, the first connector 141 is located on the first circuit board 110, the second connector 142 is located on the second circuit board 120, and the first connector 141 is plugged with the second connector 142; the guide sleeve 150 is located on the first circuit board 110, the connection assembly 130 includes a first connection portion 131 and a second connection portion 132, the first connection portion 131 is located on the guide sleeve 160, the second connection portion 132 is located on the second circuit board 120, the first connection portion 131 is connected to the second connection portion 132 and there is a tension between the first connection portion 131 and the second connection portion 132 to reduce the gap between the first connector 141 and the second connector 142.

[0069] The first circuit board 110 and the second circuit board 120 are two circuit boards that need to be electrically connected in the computing device 100. For example, the first circuit board 110 may be a main board or a backplane, and the second circuit board 120 may be a network card, a GPU (Graphics Processing Unit) board, etc.

[0070] The first circuit board 110 has a first connector 141, and the second circuit board 120 has a second connector 142. One of the first connector 141 and the second connector 142 is a male connector, and the other is a female connector. The first circuit board 110 includes a first board edge 111, and the first board edge 111 faces the second circuit board 120. The second circuit board 120 includes a second board edge 121, and the second board edge 121 faces the first board edge 111 of the first circuit board 110.

[0071] The first connector 141 is disposed near the first board edge 111, and the second connector 142 is disposed near the second board edge 121. The first connector 141 and the second connector 142 are plugged together to electrically connect the first circuit board 110 with the second circuit board 120. According to the requirements for the electrical connection between the first circuit board 110 and the second circuit board 120, the connector assembly 140 can be one, two, or more than two. Figure 1 and Figure 2 In the illustrated embodiment, the number of connector assemblies 140 is two.

[0072] Figure 3 A schematic diagram of the connection method of the connector assembly in the computing device provided in an embodiment of the present application.

[0073] See also Figure 3 As shown, the first connector 141 may be a male connector, and the first connector 141 includes a male housing 1411 and a pin 1412 located in the male housing 1411. The second connector 142 may be a female connector, and the second connector 142 includes a female housing 1421 and a socket 1422 located in the female housing 1421. The pin 1412 is inserted into the socket 1422 to electrically connect the first connector 141 and the second connector 142, and the gap D refers to the gap between the male housing 1411 and the female housing 1421 when the first connector 141 and the second connector 142 are plugged in. Of course, in other embodiments, the first connector may also be a female connector, and the second connector may be a male connector.

[0074] The larger the gap D between the first connector 141 and the second connector 142, the greater the impedance when transmitting signals between the first connector 141 and the second connector 142, and the impedance may interfere with the signal transmission between the first circuit board 110 and the second circuit board 120. Therefore, the gap D may reduce the quality of signal transmission between the first circuit board 110 and the second circuit board 120.

[0075] exist Figure 1 and Figure 2 In the illustrated embodiment, the gap between the first connector 141 and the second connector 142 is reduced by providing a connecting assembly 130 .

[0076] Figure 4 A schematic diagram of the structure of a guide sleeve in a computing device provided in an embodiment of the present application; Figure 5 For along Figure 1 Section view of the AA plane.

[0077] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the guide sleeve 150 is arranged on the first circuit board 110 near the first connector 141, and the second circuit board 120 has a guide pin 160, which is arranged near the second connector 142. The guide sleeve 150 has a limiting hole 151, and the guide pin 160 is inserted in the limiting hole 151 to align the first connector 141 and the second connector 142 when plugged in.

[0078] Specifically, when plugging the first connector 141 and the second connector 142, in order to align the pin 1412 in the first connector 141 with the socket 1422 in the second connector 142, it is necessary to set a guiding mechanism in the computing device 100, and the guiding mechanism includes a guide sleeve 150 and a guide pin 160, the guide sleeve 150 is set on the first circuit board 110, and the guide pin 160 is set on the second circuit board 120.

[0079] The guide sleeve 150 has a limiting hole 151, and the guide pin 160 includes a guide pin body 161 and a guide post 162. The guide pin body 161 is connected to the second circuit board 120, and the guide post 162 extends out of the second board edge 121 of the second circuit board 120. When the first connector 141 and the second connector 142 are plugged in, the guide post 162 is aligned with the limiting hole 151, and the guide post 162 is deeply inserted into the limiting hole 151 to limit the position of the first connector 141 and the second connector 142.

[0080] The distance between the guide sleeve 150 and the first connector 141 is small, and the corresponding distance between the guide pin 160 and the second connector 142 is also small. Therefore, when the guide sleeve 150 and the guide pin 160 are used to limit the insertion of the first connector 141 and the second connector 142, the tolerance caused by the distance can be reduced, so that the first connector 141 and the second connector 142 are better aligned.

[0081] Please continue to see Figure 1 and Figure 2 As shown, the connection assembly 130 includes a first connection portion 131 located on the guide sleeve 160 and a second connection portion 132 located on the second circuit board 120. The first connection portion 131 and the second connection portion 132 are connected. After the first connection portion 131 and the second connection portion 132 are connected, there is a tension between the first connection portion 131 and the second connection portion 132. The tension between the first connection portion 131 and the second connection portion 132 can make the first board edge 111 and the second board edge 121 close to each other, so that the gap D between the first connector 141 and the second connector 142 can be reduced.

[0082] By disposing the first connecting portion 131 on the guide sleeve 150 , it is unnecessary to dispose additional components on the first circuit board 110 , and more space can be provided on the first circuit board 110 for arranging other electronic components, so as to fully utilize the space on the first circuit board 110 .

[0083] It should be noted that the connection assembly 130 may be one, or two or more. When the connection assembly 130 is two or more, the connection assembly 130 may be spaced apart from the connector assembly 140 so that the first connector 141 and the second connector 142 in each connector assembly 140 are subjected to a more balanced force. Figure 1 and Figure 2 In the illustrated embodiment, two connection assemblies 130 are shown, wherein two connector assemblies 140 are arranged adjacent to each other, two guide sleeves 150 are arranged on both sides of two first connectors 141 along the first direction X, and two guide pins 160 are arranged on both sides of two second connectors 142 along the first direction X.

[0084] The computing device 100 provided in the embodiment of the present application is provided with a first circuit board 110, a second circuit board 120, a first connector 141, a second connector 142, a connection assembly 130 and a guide sleeve 150; the first connector 141 is located on the first circuit board 110, the second connector 142 is located on the second circuit board 120, and the first connector 141 is plugged with the second connector 142; the guide sleeve 150 is located on the first circuit board 110; the connection assembly 130 includes a first connection portion 131 and a second connection portion 132, the first connection portion 131 is located on the guide sleeve 150, the second connection portion 132 is located on the second circuit board 120, and the first connection portion 131 is plugged with the second connection portion 132. The connecting portion 132 is connected so that there is a tension between the first connecting portion 131 and the second connecting portion 132. The tension between the first connecting portion 131 and the second connecting portion 132 can make the first board edge 111 and the second board edge 121 close to each other, so that the gap D between the first connector 141 and the second connector 142 can be reduced. In addition, the first connecting portion 131 is set on the guide sleeve 150 and the second connecting portion 132 is set on the second circuit board 120. There is no need to additionally set other structural parts in the computing device 100 to reduce the gap D between the first connector 141 and the second connector 142, thereby simplifying the internal structure of the computing device 100.

[0085] Please continue to see Figure 2 , Figure 4 and Figure 5 As shown, the first connection portion 131 is a threaded hole 1311 provided on the guide sleeve 150 , and the second connection portion 132 has a screw rod 1321 at one end facing the first connection portion 131 , and the screw rod 1321 is threadedly connected to the threaded hole 1311 .

[0086] Specifically, the size of the guide sleeve 150 can be increased along the first direction X or the third direction Z, so as to provide the threaded hole 1311 on the guide sleeve 150. The threaded hole 1311 can be located above or below the limiting hole 151 along the third direction Z, and the threaded hole 1311 can also be arranged side by side with the limiting hole 151 along the first direction X. The inner wall of the threaded hole 1311 has an internal thread, and the outer wall of the screw rod 1321 has an external thread. When the screw rod 1321 is screwed into the threaded hole 1311, the first board edge 111 and the second board edge 121 are brought closer to each other during the process of being screwed into the threaded hole 1311, thereby reducing the gap D between the first connector 141 and the second connector 142.

[0087] In addition, there is a deviation between the actual position and the designed position of the first connector 141 on the first circuit board 110, there is a deviation between the actual position and the designed position of the second connector 142 on the second circuit board 120, and there is a difference in the gap D between the first connector 141 and the second connector 142. Through the threaded connection between the screw 1321 and the threaded hole 1311, the depth of the screw 1321 screwed into the threaded hole 1311 can be adjusted according to the size of the gap D between the first connector 141 and the second connector 142, so as to avoid the pressure between the first connection part 131 and the second connection part 132 being too large, resulting in the squeezing force between the first connector 141 and the second connector 142.

[0088] The edge of the second circuit board 120 opposite to the second edge 121 along the second direction Y is the third edge 122. The second connection portion 132 has a cross or slotted groove on its end facing the third edge 122. The operator inserts a screwdriver or other operating tool into the groove and rotates it to screw the screw 1321 into the threaded hole 1311. Figure 1 and Figure 2 In the illustrated embodiment, the second connection portion 132 extends out of the third board edge 122 toward one end of the third board edge 122, so as to avoid interference with other electronic components on the second circuit board 120 during the operation of the operating tool. In other embodiments, the dimension of the second connection portion 132 along the second direction Y may also be set smaller.

[0089] See also Figure 1 , Figure 2 and Figure 5 As shown, the projection of the threaded hole 1311 on the first circuit board 110 overlaps with the projection of the limiting hole 151 on the first circuit board 110; the connecting component 130 also includes a first supporting member 133, the first supporting member 133 has a first through hole 1331, the first through hole 1331 is aligned with the threaded hole 1311, and the second connecting portion 132 is inserted in the first through hole 1331 so that the screw 1321 is threadedly connected to the threaded hole 1311.

[0090] The direction in which the first board edge 111 of the first circuit board 110 extends is the first direction X, the direction perpendicular to the first direction X and parallel to the board surface of the first circuit board 110 is the second direction Y, and the direction perpendicular to the board surface of the first circuit board 110 is the third direction Z.

[0091] The overlap of the projection of the threaded hole 1311 on the first circuit board 110 and the projection of the limiting hole 151 on the first circuit board 110 means that the threaded hole 1311 and the limiting hole 151 are arranged in parallel along the third direction Z, that is, setting the threaded hole 1311 on the guide sleeve 150 will not increase the size of the guide sleeve 150 along the first direction X or the second direction Y, thereby not increasing the space occupied by the guide sleeve on the board surface of the first circuit board 110, so that there is more space on the first circuit board 110 to arrange other electronic components, so as to make full use of the space on the first circuit board 110.

[0092] exist Figure 5 In the illustrated embodiment, the threaded hole 1311 is located above the limiting hole 151 along the third direction Z, and therefore, a first support member 133 needs to be provided so that the screw rod 1321 is aligned with the threaded hole 1511. Specifically, the first support member 133 may be a support plate, and one end of the first support member 133 facing the second circuit board 120 along the third direction Z is connected to the second circuit board 120, and a first through hole 1331 is provided in one end of the first support member 133 facing away from the second circuit board 120, and the first through hole 1331 is aligned with the threaded hole 1311, and the screw rod 1321 passes through the first through hole 1331 and is threadedly connected to the threaded hole 1311.

[0093] A plurality of first support members 133 may be spaced apart on the second circuit board 120 along the second direction Y, and the screw rods 1321 are sequentially inserted into the first through holes 1331 of the respective first support members 133 to increase reliability of connection between the screw rods 1321 and the second circuit board 120 .

[0094] In other possible implementations, the threaded hole 1311 may also be located below the limiting hole 151 along the third direction Z. In this case, a through hole for the screw rod 1321 to pass through also needs to be provided below the guide column 162 in the guide pin 160 .

[0095] In addition, the diameter of the screw 1321 can be made smaller than the diameter of other areas on the second connecting portion 132, so that the aperture of the threaded hole 1311 cooperating with the screw 1321 is also smaller. The smaller aperture of the threaded hole 1311 can make the size of the guide sleeve 150 smaller.

[0097] See also Figures 6 to 9 As shown, the threaded hole 1311 is formed on the side of the limiting hole 151 away from the guide pin 160, the threaded hole 1311 is connected to the limiting hole 151 and the threaded hole 1311 and the limiting hole 151 are coaxially arranged; the guide pin 160 has a second through hole 163, the second through hole 163 is aligned with the threaded hole 1311, and the second connecting part 132 is inserted in the second through hole 163 so that the screw 1321 is threadedly connected with the threaded hole 1311.

[0098] The threaded hole 1311 extends toward a side of the limiting hole 151 away from the second circuit board 120 , and the threaded hole 1311 and the limiting hole 151 together form a through hole extending along the second direction Y on the guide sleeve 150 .

[0099] The second through hole 163 is a through hole that penetrates the guide pin body 161 and the guide column 162 along the second direction Y. When the guide column 162 is inserted into the limiting hole 151, the second through hole 163 is aligned with the threaded hole 1311. The screw 1321 is inserted into the guide pin 160 through the second through hole to be threadedly connected with the threaded hole 1311.

[0100] By connecting the threaded hole 1311 with the limiting hole 151 and coaxially arranging the threaded hole 1311 and the limiting hole 151 and arranging the second through hole 163 in the guide pin 160, relative to Figure 5 In the embodiment shown, the threaded hole 1311 is provided in the guide sleeve 150 without increasing the size of the guide sleeve 150 along the third direction Z. Compared with the threaded hole 1311 and the limiting hole 151 being provided in parallel along the first direction X, the threaded hole 1311 is provided in the guide sleeve 150 without increasing the size of the guide sleeve 150 along the first direction X. Thus, the space occupied by the guide sleeve 150 on the first circuit board 110 is further reduced, so that there is more space on the first circuit board 110 for arranging other electronic components, so as to fully utilize the space on the first circuit board 110. In addition, the second connecting portion 132 does not need to be fixed with an additional support member, so that there is more space on the second circuit board 120 for arranging other electronic components, so as to fully utilize the space of the second circuit board 120.

[0102] See also Fig.10 and Fig.11 As shown, the first connection portion 131 is a slot 1312 provided on the guide sleeve 150 , and the second connection portion 132 is a connecting rod 1322 . The connecting rod 1322 has a buckle 1323 , and the buckle 1323 is engaged with the slot 1312 .

[0103] A slot 1312 can be processed on one side of the guide sleeve 150 away from the first circuit board 110, and the slot 1312 has a first limiting surface 1312a. A buckle 1323 is provided on the connecting rod 1322, and the buckle 1323 has a second limiting surface 1323a. When the buckle 1323 is engaged with the slot 1312, the first limiting surface 1213a abuts against the second limiting surface 1323a, so that there is a pulling force between the buckle 1323 and the slot 1312, thereby reducing the gap between the first connector 141 and the second connector 142. The processing method of the slot 1312 is relatively simple, and the buckle 1323 is easy to operate when engaged with the slot 1312.

[0104] Next, the specific structure and the clamping process of the buckle 1323 and the clamping slot 1312 are described.

[0105] Fig.12 Schematic diagram of the structure of the connection between the buckle and the connecting rod in the computing device provided in the embodiment of the present application Figure 1 ; Fig.13 Schematic diagram of the structure of the connection between the buckle and the connecting rod in the computing device provided in the embodiment of the present application Figure 2 .

[0106] See also Fig.12 and Fig.13 As shown, the outer wall of the connecting rod 1322 is recessed with a mounting groove 1322a perpendicular to the axial direction of the connecting rod 1322, and the space in the mounting groove 1322a is slightly larger than the outer contour of the buckle 1323. The second connecting portion 132 also includes an elastic member 1324, which can be a spring or an elastic sleeve. One end of the elastic member 1324 is connected to the bottom wall 1322b of the mounting groove 1322a, and the other end of the elastic member 1324 is connected to the buckle 1323. When the elastic member 1324 is in a naturally extended state, such as Fig.13 , the buckle 1323 extends out of the outer wall of the connecting rod 1322 and is located outside the mounting groove 1322a; when the elastic member 1324 is in a compressed state, such as Fig.12 The buckle 1323 is flush with the outer wall of the connecting rod 1322 and is located inside the mounting groove 1322a.

[0107] The connecting rod 1322 moves toward the guide sleeve 150 along the second direction Y until the buckle 1323 contacts the surface of the guide sleeve 150, and the guide sleeve 150 applies pressure on the buckle 1323. The buckle 1323 compresses the elastic member 1324 so that the buckle 1323 can move toward the installation groove 1322a, so that the outer wall of the buckle 1323 and the connecting rod 1322 remain flush, thereby, the connecting rod 1322 can drive the buckle 1323 to continue to move toward the slot 1312.

[0108] Please continue to see Fig.10As shown, when the buckle 1323 moves to align with the slot 1312 along the third direction Z, the buckle 1323 extends from the outer wall of the connecting rod 1322 under the elastic force of the elastic member 1324, enters the slot 1312 and engages with the slot 1312. The elastic member 1324 connects the buckle 1323 and the connecting rod 1322, which can avoid interference between the guide sleeve 150 and the buckle 1323, making the engagement process between the buckle 1323 and the slot 1312 more convenient. In addition, the slot 1312 is provided on the guide sleeve 150, relative to Figure 5 For the illustrated embodiment, the dimension of the guide sleeve 150 along the third direction Z can also be reduced.

[0109] Please continue to see Fig.10 and Fig.11 As shown, the connection assembly 130 further includes a second support member 134 , the second support member 134 has a third through hole 1341 , and the connecting rod 1322 is inserted into the third through hole 1341 .

[0110] The slot 1312 is located on the upper surface of the limiting hole 151 along the third direction Z, so the second support member 134 needs to be provided so that the buckle 1323 on the connecting rod 1322 is aligned with the slot 1312. Specifically, the second support member 134 can be a support plate, and one end of the second support member 134 facing the second circuit board 120 is connected to the second circuit board 120, and a third through hole 1341 is provided in one end of the second support member 134 away from the second circuit board 120, and the connecting rod 1322 passes through the third through hole 1341 so that the buckle 1323 is engaged with the slot 1312.

[0111] A plurality of second support members 134 may be spaced apart on the second circuit board 120 along the second direction Y, and the connecting rod 1322 may be sequentially inserted into the third through hole 1341 of each second support member 134 to increase reliability of the connection between the connecting rod 1322 and the second circuit board 120 .

[0112] In other embodiments, the locking groove 1312 may also be disposed on two opposite surfaces of the guide sleeve 150 along the first direction X.

[0113] Fig.14 A schematic diagram of the structure of a computing device provided in an embodiment of the present application Figure 2 .in, Fig.10 The upper cover is omitted, and the housing 170 of the computing device 100 is shown with dotted lines to clearly show the internal structure of the housing 170 .

[0114] See also Fig.14As shown, the connection assembly 130 may further include a wrench 135, which is connected to the connecting rod 1322 and the wrench 135 and the buckle 1323 are arranged at opposite ends of the connecting rod 1322; the computing device 100 also includes a shell 170, and the wrench 135 abuts against the shell 170 to make the buckle 1323 engage with the slot 1312.

[0115] The shell 170 can be a rectangular structure, and the shell 170 includes a bottom wall 171, an upper cover (not shown in the figure) and four side walls 172. The four side walls 172 are respectively a first side wall 1721, a second side wall 1722, a third side wall 1723 and a fourth side wall 1724. The first side wall 1721, the second side wall 1722, the third side wall 1723 and the fourth side wall 1724 and the bottom wall 171 form a accommodating cavity 173. The first circuit board 110 and the second circuit board 120 are both arranged in the shell 170. The accommodating cavity 173 is also provided with a power supply, a fan and other components.

[0116] The fourth side wall 1724 is provided with an opening 1724 a which may be a rectangular structure. The dimension of the opening 1724 a along the first direction X is larger than the length of the wrench 135 , and the dimension of the opening 1724 a along the third direction Z is smaller than the length of the wrench 135 .

[0117] The end of the connecting rod 1322 may be provided with a mounting hole, the inner wall of the mounting hole is provided with a thread, the spanner 135 is provided with a pin 136, the pin 136 is fixedly connected to the spanner 135, and the outer wall of the pin 136 facing the end of the connecting rod 1322 is provided with an external thread. The pin 136 is screwed into the mounting hole of the connecting rod 1322, so that the spanner 135 and the connecting rod 1322 can be rotatably connected. By rotating the pin 136, the wrench 135 is first rotated relative to the connecting rod 1322 to be parallel to the first direction X. When the connecting rod 1322 moves along the second direction Y until the buckle 1323 is engaged with the slot 1312, the wrench 135 is pulled toward the opening 1724a along the second direction Y, so that the wrench 135 drives the connecting rod 1322 and the buckle 1323 on the connecting rod to move toward the opening 1724a. The tension between the buckle 1323 and the slot 1312 makes the first board edge 111 and the second board edge 121 approach each other, thereby reducing the gap D1 between the first connector 141 and the second connector 142; the wrench 135 is rotated relative to the connecting rod 1322 until it is parallel to the third direction Z, and then the wrench 135 is abutted against the side of the opening 1724a away from the fourth side wall 1724a.

[0118] By setting a wrench 135 on the connecting rod 1322 and making the wrench 135 abut against the shell 170, a stable pulling force can be maintained between the buckle 1323 and the slot 1312, so that the first board edge 111 and the second board edge 121 are close to each other, thereby reducing the gap D1 between the first connector 141 and the second connector 142.
