Description

Technical Field

[0001] The utility model relates to the technical field of integrated circuits, in particular to a connection auxiliary device and a connection structure. Background Art

[0002] With the increase in the connection density between circuit boards, in many scenarios, two or more printed circuit boards (PCBs) are connected, and there are generally male and female mating connectors or wiring harness cables between them to achieve communication transmission and power supply between the two. Among them, for two printed circuit boards (PCBs) with multiple sets of male and female mating connectors, since the two printed circuit boards (PCBs) need to be connected and separated during the debugging and maintenance stage, it is necessary to overcome the force of multiple sets of connectors during operation. If the additional mechanical structure is not considered, it is difficult to achieve the connection and separation of the two printed circuit boards (PCBs) only through simple manual work. Moreover, the printed circuit board (PCB) is easily deformed and warped during the operation. Therefore, there is an urgent need for a connection auxiliary device and a connection structure that can assist in the connection and separation between printed circuit boards (PCBs), reduce the difficulty of operation, and reduce the deformation of the printed circuit board (PCB) during connection and separation. Utility Model Content

[0003] The present application provides a connection auxiliary device and a connection structure, which can assist in connecting and separating printed circuit boards (PCBs), reduce the difficulty of operation, and reduce the deformation of the printed circuit boards (PCBs) during connection and separation.

[0004] A first aspect of the present application provides a connection auxiliary device, which assists a first connector on a first PCB board to be plugged and unplugged with a second connector on a second PCB board along a connection direction, comprising: a first connector, which is fixed on the first PCB board, and is provided with a first through-hole-shaped threaded hole, and the axial direction of the first threaded hole is the same as the connection direction; a second connector, which is fixed on the second PCB board; and an operating member, which has a connecting end and an operating end coaxially arranged, and the connecting end is threadedly connected to the first threaded hole.

[0005] With the above structure, when it is necessary to operate the first connector on the first PCB board to connect and separate with the second connector on the second PCB board, the first threaded hole of the first connector can be threadedly connected through the connecting end of the operating member. Thus, the staff can operate and apply force to the first connector and the first PCB board through the operating end of the operating member, so that the first connector on the first PCB board and the second connector on the second PCB board can be easily connected and separated, thereby reducing the operating difficulty of the staff. In addition, by fixing the first connector on the first PCB board and fixing the second connector on the second PCB board, the structural strength of the first PCB board and the second PCB board can be improved, and when the first connector on the first PCB board and the second connector on the second PCB board are connected and separated, the deformation of the first PCB board and the second PCB board can be reduced.

[0006] At the same time, the length of the connecting end of the above-mentioned operating member can be less than or equal to the depth of the first threaded hole, or greater than the depth of the first threaded hole, and both can realize the separation of the first PCB board and the second PCB board. The difference between these two schemes is that when the length of the connecting end of the connecting member is greater than the depth of the first threaded hole and greater than the preset distance, another method can also be used to realize the separation of the first connector and the second connector. Specifically, since the first threaded hole is a through hole, after the connecting end of the operating member is threadedly connected with the first threaded hole, the staff can also continue to rotate the operating end so that the end of the connecting end passes through the first threaded hole and abuts against the second connecting member, and increase the length of the connecting end passing through the first threaded hole by rotating the operating part, thereby driving the first connecting member to separate from the second connecting member, and then separating the first connector on the first PCB board from the second connector on the second PCB board. Thus, the difficulty of operation can be further reduced, which is convenient for the staff to separate the first connector from the second connector. Moreover, by rotating the operating end so that the connecting end abuts against the second connecting member to drive the first connector to separate from the second connector, the force position can be located on the first connecting member and the second connecting member, thereby reducing the deformation of the first PCB board and the second PCB board when they are separated.

[0007] As a possible implementation method of the first aspect, a second threaded hole is provided on the second connecting member at a position corresponding to the first threaded hole, the axial direction of the second threaded hole is the same as the connection direction, and the diameter of the second threaded hole is smaller than the first threaded hole; and further comprising: a screw, which is adapted to the second threaded hole and is used to pass through the first threaded hole and be threadedly connected to the second threaded hole, thereby driving the first connecting member and the second connecting member to approach each other.

[0008] With the above structure, by setting the second threaded hole along the connection direction on the second connector, when the first connector and the second connector are plugged and unplugged, the screw can be passed through the first threaded hole to be threadedly connected with the second threaded hole, and then the screw is rotated to penetrate into the second threaded hole, so that the head of the screw abuts against the first connector, and the first connector is pushed toward the second connector, so that the first connector on the first PCB is inserted into the second connector on the second PCB. In this way, the connection between the first connector and the second connector can be completed by rotating the screw, thereby reducing the difficulty of operation.

[0009] In addition, the position and direction of the first PCB board and the second PCB board after being connected are not fixed. If the connection and fixation are only performed by plugging and unplugging the first connector and the second connector, there is a possibility of looseness between the first connector and the second connector, which will affect the electrical connection effect. In the present application, the first connector and the second connector are fixed by screws, so that the position of the first connector and the second connector can be fixed. In this way, looseness between the first connector and the second connector can be avoided, so that the stability of the electrical connection between the first connector and the second connector can be improved.

[0010] As a possible implementation manner in the first aspect, the first connecting member is disposed on a side of the first PCB board away from the second PCB board, and the second connecting member is disposed on a side of the second PCB board facing the first PCB board.

[0011] As a possible implementation of the first aspect, a first guide portion is provided on the first connecting member, and a second guide portion is provided on the second connecting member at a position corresponding to the first guide portion, and the first guide portion and the second guide portion are pluggably connected along the connecting direction.

[0012] By adopting the above structure, by providing a first guide portion and a second guide portion for plugging and unplugging the connection along the connection direction, when the first connector and the second connector are plugged and unplugged, the first guide portion and the second guide portion cooperate to guide the movement direction of the first connector and the second connector, and then guide the movement direction of the first connector on the first PCB board and the second connector on the second PCB board, so that the first connector and the second connector can be correctly plugged and unplugged, thereby avoiding damage to the first connector and the second connector due to incorrect position during connection.

[0013] In addition, by providing the first guide portion and the second guide portion, when the first connector is separated from the second connector, it is also possible to avoid the first PCB board and the second PCB board being separated asynchronously, causing the position distance difference between the two ends to be too large, thereby avoiding damage to the first connector and the second connector during separation.

[0014] As a possible implementation manner in the first aspect, the first guide portions are disposed at corresponding positions on both sides of the first connector, and the second guide portions are disposed at corresponding positions on both sides of the second connector.

[0015] By adopting the above structure, by arranging the first guide part and the second guide part at corresponding positions on both sides of the first connector and the second connector respectively, the first connector and the second connector can be better guided when the first connector and the second connector are plugged in and unplugged, thereby avoiding damage to the first connector and the second connector when they are plugged in and unplugged.

[0016] As a possible implementation of the first aspect, a plurality of first threaded holes are provided, which are respectively arranged near the two end positions of the first connecting member; a plurality of second threaded holes are provided, which are respectively arranged near the two end positions of the second connecting member; the first guide portion is located in the middle position of two adjacent first threaded holes, and the second guide portion is located in the middle position of two adjacent second threaded holes.

[0017] By adopting the above structure and setting a plurality of first threaded holes, the positions where the first connector and the second connector are subjected to force when approaching and separating can be made more uniform, thereby avoiding deviation from the connection direction when driving the first connector on the first PCB board and the second connector on the second PCB board to connect and separate. Thus, the difficulty of operation can be reduced. In addition, by locating the first guide portion in the middle of two adjacent first threaded holes and locating the second guide portion in the middle of two adjacent second threaded holes, the moving directions of the first connector and the second connector can be better guided when driving the first connector and the second connector to approach and separate, making the process of approaching and separating the first connector and the second connector smoother, thereby reducing the difficulty of operation.

[0018] As a possible implementation manner in the first aspect, a avoidance hole is provided on the second connecting member, and the second connector is located in the avoidance hole.

[0019] With the above structure, by providing an avoidance hole on the second connector, the second connector is located in the avoidance hole, so that the second connector can be protected by the avoidance hole. At the same time, when the second connector drives the second PCB board and the second connector to move, the driving force around the second connector can be made more uniform. In addition, by providing the avoidance hole on the second connector, the weight of the second connector can be reduced, thereby reducing the weight of the connection auxiliary device.

[0020] As a possible implementation of the first aspect, the second connector has a plurality of pins; the depth of the avoidance hole is greater than the height of the pin protruding from the second PCB board.

[0021] With the above structure, the depth of the avoidance hole is greater than the height of the pin, so that the pin can be completely hidden in the avoidance hole, thereby protecting the second connector and preventing the pin from being damaged.

[0022] As a possible implementation manner of the first aspect, a plurality of the second connectors are provided corresponding to the avoidance holes; and reinforcing ribs are formed between adjacent avoidance holes.

[0023] By adopting the above structure, reinforcing ribs are formed between the avoidance holes, so that the structural strength between the avoidance holes and the second connector can be improved.

[0024] As a possible implementation manner in the first aspect, a flow channel is provided in the first connecting member and / or the second connecting member, and the flow channel is used to circulate cooling liquid.

[0025] With the above structure, by providing flow channels in the first connector and the second connector, the components on the first PCB board and the second PCB board can be cooled by circulating cooling liquid in the flow channels, thereby preventing the components on the first PCB board and the second PCB board from being overheated and affecting the working efficiency.

[0026] The second aspect of the present application provides a connection structure, including: a first PCB board, on which a first connector is arranged; a second PCB board, on which a second connector is arranged; a connection auxiliary device, which is a connection auxiliary device as described in any one of the first aspects of the present application, and assists the first connector on the first PCB board and the second connector on the second PCB board to be plugged and connected along a connection direction.

[0027] With the above structure, when it is necessary to operate the first connector on the first PCB board to connect and separate with the second connector on the second PCB board, the first threaded hole of the first connector can be threadedly connected through the connecting end of the operating member. Thus, the staff can operate and apply force to the first connector and the first PCB board through the operating end of the operating member, so that the first connector on the first PCB board and the second connector on the second PCB board can be easily connected and separated, thereby reducing the operating difficulty of the staff. In addition, by fixing the first connector on the first PCB board and fixing the second connector on the second PCB board, the structural strength of the first PCB board and the second PCB board can be improved, and when the first connector on the first PCB board and the second connector on the second PCB board are connected and separated, the deformation of the first PCB board and the second PCB board can be reduced.

[0028] At the same time, the length of the connection end of the above-mentioned operating member can be less than or equal to the depth of the first threaded hole, or greater than the depth of the first threaded hole, and both can realize the separation of the first PCB board and the second PCB board. The difference between the two schemes is that when the length of the connection end of the operating member is greater than the depth of the first threaded hole and greater than the preset distance, another method can also be used to realize the separation of the first connector and the second connector. Specifically, since the first threaded hole is a through hole, after the connection end of the operating member is threadedly connected with the first threaded hole, the staff can also continue to rotate the operating end so that the end of the connection end passes through the first threaded hole and abuts against the second connecting member, and increase the length of the connection end passing through the first threaded hole by rotating the operating part, thereby driving the first connecting member to separate from the second connecting member, and then separating the first connector on the first PCB board from the second connector on the second PCB board. Thus, the difficulty of operation can be further reduced, which is convenient for the staff to separate the first connector from the second connector. Moreover, by rotating the operating end so that the connection end abuts against the second connecting member to drive the first connector to separate from the second connector, the force position can be located on the first connecting member and the second connecting member, thereby reducing the deformation of the first PCB board and the second PCB board when they are separated.

[0029] As a possible implementation of the second aspect, a plurality of first connectors and a plurality of second connectors are correspondingly arranged along the first direction, and a distance between adjacent first connectors is less than an average width of the plurality of first connectors; and / or a distance between adjacent second connectors is less than an average width of the plurality of second connectors; a distance between the first connector close to an edge of the first PCB board along the first direction and an edge of the first PCB board is less than or equal to an average width of the plurality of first connectors; and / or a distance between the second connector close to an edge of the second PCB board along the first direction and an edge of the second PCB board is less than or equal to an average width of the plurality of second connectors.

[0030] By adopting the above structure, the distance between the first connector and the second connector is limited, and the distance between the first connector, the second connector and the edges of the corresponding first PCB board and the second PCB board is limited, so that the first connector and the second connector can be more compact on the first PCB board and the second PCB board, and the first connector and the second connector on the first PCB board and the second PCB board can be more stable when plugging and unplugging.

[0046] Below, in conjunction with the accompanying drawings, possible embodiments of the connection auxiliary device 10 in the present application are exemplarily described.

[0047] Figure 1 This is one of the three-dimensional structural schematic diagrams of the connection structure 1 in this application; Figure 2 for Figure 1 The second schematic diagram of the three-dimensional structure of the connecting structure 1; Figure 3 for Figure 1 FIG. 4( a) is a schematic diagram of a three-dimensional structure after the first PCB board 20 and the second PCB board 30 are separated; ...

[0048] Figure 4(b) shows Figure 1 A cross-sectional schematic diagram of the connection auxiliary device 10 separating or connecting the first PCB board 20 and the second PCB board 30; Figure 5 for Figure 1Schematic diagram of the structure of the first PCB board 20.

[0049] like Figure 1-Figure 5 As shown, the connection auxiliary device 10 in the present application is used to assist the first connector 21 on the first PCB board 20 and the second connector 31 on the second PCB board 30 to plug and unplug the connection along the connection direction. The connection auxiliary device 10 includes a first connector 100, a second connector 200 and an operating member 400. Among them, the first connector 100 is fixed on the first PCB board 20, and a through-hole-shaped first threaded hole 110 is provided on the first connector 100, and the axial direction of the first threaded hole 110 is the same as the connection direction. The second connector 200 is fixed on the second PCB board 30. The operating member 400 has a coaxially arranged connection end 410 and an operating end 420, and the connection end 410 is threadedly connected to the first threaded hole 110.

[0050] As described above, when the first connector 21 on the first PCB board 20 and the second connector 31 on the second PCB board 30 need to be connected and separated, the first threaded hole 110 of the first connector 100 can be threadedly connected through the connection end 410 of the operating member 400. Therefore, the staff can operate and apply force to the first connector 100 and the first PCB board 20 through the operating end 420 of the operating member 400, so that the first connector 21 on the first PCB board 20 and the second connector 31 on the second PCB board 30 can be conveniently operated to connect and separate, thereby reducing the difficulty of operation for the staff. In addition, by fixing the first connector 100 on the first PCB board 20 and fixing the second connector 200 on the second PCB board 30, the structural strength of the first PCB board 20 and the second PCB board 30 can be improved, and when the first connector 21 on the first PCB board 20 and the second connector 31 on the second PCB board 30 are connected and separated, the deformation of the first PCB board 20 and the second PCB board 30 can be reduced.

[0051] At the same time, the length of the connection end 410 of the operating member 400 can be less than or equal to the depth of the first threaded hole 110, or greater than the depth of the first threaded hole 110, and both can achieve the separation of the first PCB board 20 and the second PCB board 30. The difference between the two solutions is that when the length of the connection end 410 of the operating member 400 is greater than the depth of the first threaded hole 110 and greater than the preset distance, another method can be used to achieve the separation of the first connector 21 and the second connector 31. Specifically, since the first threaded hole 110 is a through hole, after the connection end 410 of the operating member 400 is threadedly connected with the first threaded hole 110, the staff can continue to rotate the operating end 420 to make the end of the connection end 410 pass through the first threaded hole 110 and abut against the second connector 200, and increase the length of the connection end 410 passing through the first threaded hole 110 by rotating the operating end 420, thereby driving the first connector 100 to separate from the second connector 200, and then separating the first connector 21 on the first PCB board 20 from the second connector 31 on the second PCB board 30. Thus, the difficulty of operation can be further reduced, and it is convenient for the staff to separate the first connector 21 and the second connector 31. Moreover, by rotating the operating end 420 to make the connection end 410 abut against the second connector 200 to drive the first connector 21 and the second connector 31 to separate, the force-bearing position can be located on the first connector 100 and the second connector 200, thereby reducing the deformation of the first PCB board 20 and the second PCB board 30 when they are separated.

[0052] In some embodiments, a second threaded hole 210 is provided on the second connecting member 200 at a position corresponding to the first threaded hole 110, the axial direction of the second threaded hole 210 is the same as the connection direction, and the diameter of the second threaded hole 210 is smaller than the first threaded hole 110; and also includes: a screw 300, which is adapted to the second threaded hole 210 and is used to pass through the first threaded hole 110 and be threadedly connected to the second threaded hole 210, thereby driving the first connecting member 100 and the second connecting member 200 to approach each other.

[0053] As described above, by providing the second threaded hole 210 along the connection direction on the second connector 200, when the first connector 21 and the second connector 31 are plugged and unplugged, the screw 300 can be passed through the first threaded hole 110 to be threadedly connected with the second threaded hole 210, and then the screw 300 is rotated to make the screw 300 penetrate into the second threaded hole 210, so that the head of the screw 300 abuts against the first connector 100, and the first connector 100 is pushed toward the second connector 200, so that the first connector 21 on the first PCB board 20 is inserted into the second connector 31 on the second PCB board 30. Therefore, the connection between the first connector 21 and the second connector 31 can be completed by rotating the screw 300, thereby reducing the difficulty of operation.

[0054] In addition, the position and direction of the first PCB board 20 and the second PCB board 30 after connection are not fixed. If the connection and fixation are only performed by plugging and unplugging the first connector 21 and the second connector 31, there is a possibility of looseness between the first connector 21 and the second connector 31, which will affect the electrical connection effect. In the present application, the first connector 100 and the second connector 200 are fixed by screws 300, so that the position of the first connector 21 and the second connector 31 can be fixed. In this way, looseness between the first connector 21 and the second connector 31 can be avoided, so that the stability of the electrical connection between the first connector 21 and the second connector 31 can be improved.

[0055] At the same time, it should be noted that the screw 300 and the operating member 400 both need to use the first threaded hole 110 when in use, so the screw 300 and the operating member 400 are not used at the same time. The user can use the screw 300 or the operating member 400 as needed to connect and separate the first connector 21 and the second connector 31.

[0056] In some embodiments, the first connector 100 is disposed on a side of the first PCB board 20 away from the second PCB board 30 , and the second connector 200 is disposed on a side of the second PCB board 30 facing the first PCB board 20 .

[0057] In some embodiments, a first guide portion 120 is disposed on the first connector 100 , and a second guide portion 220 is disposed on the second connector 200 at a position corresponding to the first guide portion 120 . The first guide portion 120 and the second guide portion 220 are pluggably connected along a connection direction.

[0058] As described above, by providing the first guide portion 120 and the second guide portion 220 that are plugged in and out along the connection direction, when the first connector 21 and the second connector 31 are plugged in and out, the first guide portion 120 and the second guide portion 220 cooperate to guide the movement direction of the first connector 100 and the second connector 200, and then guide the movement direction of the first connector 21 on the first PCB board 20 and the second connector 31 on the second PCB board 30, so that the first connector 21 and the second connector 31 can be correctly plugged in and out, thereby avoiding damage to the first connector 21 and the second connector 31 due to incorrect position during connection.

[0059] In addition, by providing the first guide portion 120 and the second guide portion 220, when the first connector 21 and the second connector 31 are separated, it is also possible to avoid that the first PCB board 20 and the second PCB board 30 are separated asynchronously, causing the position distance difference between the two ends to be too large, thereby avoiding damage to the first connector 21 and the second connector 31 during separation.

[0060] In some embodiments, the first guide portion 120 is disposed at corresponding positions on both sides of the first connector 21, and the second guide portion 220 is disposed at corresponding positions on both sides of the second connector 31. Thus, by disposing the first guide portion 120 and the second guide portion 220 at corresponding positions on both sides of the first connector 21 and the second connector 31, respectively, the first connector 21 and the second connector 31 can be better guided when the first connector 21 and the second connector 31 are plugged and unplugged, thereby avoiding damage to the first connector 21 and the second connector 31 when they are plugged and unplugged.

[0061] In some embodiments, a plurality of first threaded holes 110 are provided, which are respectively arranged at two end positions close to the first connecting member 100; a plurality of second threaded holes 210 are provided, which are respectively arranged at two end positions close to the second connecting member 200; the first guide portion 120 is located in the middle position between two adjacent first threaded holes 110, and the second guide portion 220 is located in the middle position between two adjacent second threaded holes 210.

[0062] In some embodiments, two first threaded holes 110 are respectively provided at positions at both ends of the first connector 100 corresponding to the first connector 21, and a first guide portion 120 is provided in the middle of the two first threaded holes 110. Two second threaded holes 210 are respectively provided at positions at both ends of the second connector 200 corresponding to the second connector 31, and a second guide portion 220 is provided in the middle of the two second threaded holes 210.

[0063] From the above, by providing a plurality of first threaded holes 110, the positions where the first connector 100 and the second connector 200 are subjected to force when approaching and separating can be made more uniform, thereby avoiding deviation from the connection direction when driving the first connector 100 on the first PCB board 20 and the second connector 200 on the second PCB board 30 to connect and separate. Thus, the difficulty of operation can be reduced. In addition, by making the first guide portion 120 located in the middle position of two adjacent first threaded holes 110, and making the second guide portion 220 located in the middle position of two adjacent second threaded holes 210, the moving directions of the first connector 100 and the second connector 200 can be better guided when driving the first connector 100 and the second connector 200 to approach and separate, so that the process of approaching and separating the first connector 100 and the second connector 200 is smoother, thereby reducing the difficulty of operation.

[0064] In some embodiments, the first connector 100 is provided with an escape portion 130, and the escape portion 130 is located at a position corresponding to the first connector 21. Specifically, the escape portion 130 may be, for example Figure 1-Figure 3The rectangular through hole shown in the figure may also be a concave shape with the opening facing the first PCB board 20, and there is no limitation on this. Therefore, by providing the avoidance portion 130 on the first connector 100, when the first connector 100 drives the first PCB board 20 and the first connector 21 to move, the driving force around the first connector 21 can be made more uniform. In addition, by providing the avoidance portion 130 on the first connector 100, the weight of the first connector 100 can also be reduced, thereby reducing the weight of the connection auxiliary device 10. At the same time, by providing the avoidance portion 130, the welding position of the first connector 21 on the first PCB board 20 can also be avoided to avoid short circuit.

[0065] In some embodiments, the second connector 200 is provided with a first avoidance hole 230, and the second connector 31 is located in the first avoidance hole 230. Therefore, by providing the first avoidance hole 230 on the second connector 200, the second connector 31 is located in the first avoidance hole 230, so that the second connector 31 can be protected by the first avoidance hole 230. At the same time, when the second connector 200 drives the second PCB board 30 and the second connector 31 to move, the driving force around the second connector 31 can be made more uniform. In addition, by providing the first avoidance hole 230 on the second connector 200, the weight of the second connector 200 can be reduced, thereby reducing the weight of the connection auxiliary device 10.

[0066] In some embodiments, the second connector 31 has a plurality of pins; the depth of the first avoidance hole 230 is greater than the height of the pin protruding from the second PCB board 30. Thus, by making the depth of the first avoidance hole 230 greater than the height of the pin, the pin can be completely hidden in the first avoidance hole 230. Thus, the second connector 31 can be protected from being damaged.

[0067] In some embodiments, a plurality of second connectors 31 are provided corresponding to the first avoidance holes 230; and reinforcing ribs 231 are formed between adjacent first avoidance holes 230. Thus, by forming reinforcing ribs 231 between the first avoidance holes 230, the structural strength between the first avoidance holes 230 and the second connectors 31 can be improved.

[0068] In some embodiments, a flow channel 240 is provided in the first connector 100 and / or the second connector 200, and the flow channel 240 is used to circulate cooling liquid. Therefore, by providing the flow channel 240 in the first connector 100 and the second connector 200, the components on the first PCB board 20 and the second PCB board 30 can be cooled by circulating cooling liquid in the flow channel 240. Therefore, it can be prevented that the temperature of the components on the first PCB board 20 and the second PCB board 30 is too high, which affects the working efficiency.

[0069] The above content is an exemplary description of a possible embodiment of the connection auxiliary device 10 in the present application. Next, in conjunction with the accompanying drawings, the connection structure 1 in the present application and the specific structure of the connection auxiliary device 10 are described in detail in a specific embodiment.

[0070] like Figure 1-Figure 3 As shown in FIG. 4( a) and FIG. 4( b), the connection structure in the embodiment of the present application includes a first PCB board 20, a second PCB board 30, and a connection auxiliary device 10 for assisting the first PCB board 20 and the second PCB board 30 in connecting.

[0071] like Figure 1-Figure 5 As shown, the first PCB board 20 is a roughly rectangular plate-shaped component, and a plurality of first connectors 21 are evenly arranged along a straight line in the middle position of one side surface of the first PCB board 20 along the length direction of the first PCB board 20. The distance between adjacent first connectors 21 is less than the average width of the plurality of first connectors 21. The distance between the first connectors 21 located at both ends and the edge of the first PCB board 20 is less than or equal to the average width of the plurality of first connectors 21. The second PCB board 30 is a roughly rectangular plate-shaped component, and a plurality of second connectors 31 are evenly arranged along a straight line in the middle position of one side surface of the second PCB board 30 along the length direction of the second PCB board 30. The distance between adjacent second connectors 31 is less than the average width of the plurality of second connectors 31. The distance between the second connectors 31 located at both ends and the edge of the second PCB board 30 is less than or equal to the average width of the plurality of second connectors 31. The first connector 21 on the first PCB board 20 and the second connector 31 on the second PCB board 30 are arranged one by one, so that when the first PCB board 20 and the second PCB board 30 are close to each other, the first connector 21 and the second connector 31 can be plugged and unplugged.

The first connector 100 is fixed to the other side surface (the side surface opposite to the first connector 21) of the first PCB board 20 by a fastener such as a bolt, and the second connector 200 is fixed to the side surface (the same side surface as the second connector 31) of the first PCB board 20 by a fastener such as a bolt. The screw 300 can drive the first connector 100 and the second connector 200 to approach each other, thereby driving the first PCB board 20 and the second PCB board 30 to approach each other, so that the first connector 21 and the second connector 31 are connected. The operating member 400 can facilitate the user to operate, so as to drive the first PCB board 20 and the second PCB board 30 to approach or move away from each other, so that the first connector 21 and the second connector 31 are connected or disconnected.

[0073] like Figure 1-Figure 3 As shown in FIG. 4(a) and FIG. 4(b), the first connector 100 is a rectangular strip-shaped component, the length of the first connector 100 is the same as the length of the first PCB board 20, and the width of the first connector 100 is slightly larger than the dimension of the first connector 21 in the width direction of the first PCB board 20. The first connector 100 is provided with a plurality of avoidance portions 130 along its length direction (first direction), and the plurality of avoidance portions 130 are provided one-to-one with the first connector 21. The avoidance portions 130 are rectangular through holes adapted to the shape of the first connector 21, and the hole depth direction of the avoidance portions 130 is the same as the thickness direction of the first connector 21 and the first PCB board 20. Therefore, by providing the avoidance portions 130 on the first connector 100, when the first connector 100 drives the first PCB board 20 and the first connector 21 to move, the driving force around the first connector 21 can be made more uniform. In addition, by providing the avoidance portion 130 on the first connector 100, the weight of the first connector 100 can be reduced, thereby reducing the weight of the connection auxiliary device 10. At the same time, by providing the avoidance portion 130, the welding position of the first connector 21 on the first PCB board 20 can be avoided to avoid short circuit.

[0074] Figure 6 for Figure 1 Schematic diagram of the three-dimensional structure of the second connecting member 200. Figure 1-Figure 3 , Figure 4(a), Figure 4(b), and Figure 6As shown, the second connector 200 is a rectangular component, and the shape of the second connector 200 is similar to the shape and size of the first PCB board 20 and / or the second PCB board 30. The thickness of the second connector 200 is adapted to the distance between the first PCB board 20 and the second PCB board 30 after the first PCB board 20 and the second PCB board 30 are connected through the first connector 21 and the second connector 31. Specifically, the second connector 31 has a plurality of pins; the depth of the first avoidance hole 230 is greater than the height of the pin protruding from the second PCB board 30. Therefore, the pin can be protected by the first avoidance hole 230, and the two side surfaces of the second connector 200 can be respectively fitted with the first PCB board 20 and the second PCB board 30, so that the stability of the connection between the first PCB board 20 and the second PCB board 30 can be improved.

[0075] like Figure 3 , Figure 4(a), Figure 4(b), Figure 6 As shown, a plurality of first avoidance holes 230 are provided on the second connector 200, and the first avoidance holes 230 are provided at corresponding positions of the first connector 21 and the second connector 31. Reinforcing ribs 231 are formed between adjacent first avoidance holes 230, which can improve the structural strength between the first avoidance holes 230 and the second connector 31. The shape and size of the first avoidance holes 230 are adapted to the shape and size of the first connector 21 and the second connector 31, so that the first connector 21 and the second connector 31 can be plugged and unplugged in the first avoidance holes 230.

[0076] like Figure 6 As shown, a plurality of second avoidance holes 250 are further provided on the second connecting member 200, and the second avoidance holes 250 are provided at corresponding positions of the electronic components on the first PCB board 20 and the second PCB board 30, so that after the first PCB board 20 and the second PCB board 30 are connected through the first connector 21 and the second connector 31, other electronic components on the first PCB board 20 and the second PCB board 30 can be conveniently accommodated in the second avoidance holes 250, so that the second connecting member 200 can better fit with the first PCB board 20 and the second PCB board 30, so as to improve the stability of the connection between the first PCB board 20 and the second PCB board 30.

[0077] like Figure 6 As shown, the second connector 200 is further provided with a flow channel 240, and the flow channel 240 is provided around / close to the first avoidance hole 230 and the second avoidance hole 250. Specifically, the flow channel 240 is provided around / close to the second avoidance hole 250 corresponding to the electronic components that are prone to heat on the first PCB board 20 and the second PCB board 30. A coolant may flow through the flow channel 240, and the electronic components that are prone to heat in the second avoidance hole 250 may be cooled, thereby improving the performance of the electronic components.

[0078] like Figure 2 , Figure 3 As shown, the first connecting member 100 is provided with a first guide portion 120 at the middle position near both ends. The first guide portion 120 is a circular through hole extending along the thickness direction of the first connecting member 100. Figure 3 , Figure 6 As shown, the second connector 200 is provided with a second guide portion 220 at each of the middle positions near the two ends thereof corresponding to the first avoidance hole 230. The second guide portion 220 is a cylindrical component and can be fastened to the second connector 200 by screw thread. The second guide portion 220 extends along the thickness direction of the second connector 200. When the first PCB board 20 and the second PCB board 30 are close to each other, the second guide portion 220 can be inserted into the first guide portion 120, thereby guiding the moving direction of the first PCB board 20 and the second PCB board 30 to assist the first connector 21 and the second connector 31 in plugging and unplugging connection.

[0079] like Figure 1-Figure 3 As shown in FIG. 4(a) and FIG. 4(b), the first connector 100 is provided with a through-hole-shaped first threaded hole 110 at both sides (along the width direction of the first connector 100) near the first guide portion 120, and the first PCB board 20 is provided with through holes at positions corresponding to the first threaded hole 110 and the first guide portion 120 so that the screw 300, the operating member 400 and the second guide portion 220 can pass through. Figure 3 , Figure 4(a), Figure 4(b), Figure 6 As shown, the second connecting member 200 is provided with a second threaded hole 210 at both sides (along the width direction of the second connecting member 200) near the second guide portion 220. The second threaded hole 210 corresponds to the first threaded hole 110 one by one and is coaxially arranged. The specification of the thread in the first threaded hole 110 is M5, and the specification of the thread in the second threaded hole 210 is M4, that is, the aperture of the second threaded hole 210 is smaller than that of the first threaded hole 110.

[0080] As shown in FIG. 4(a), the size of the screw 300 is matched with the size of the second threaded hole 210, so that the screw rod of the screw 300 can pass through the first threaded hole 110 and be threadedly connected with the second threaded hole 210. Therefore, when it is necessary to drive the first PCB board 20 and the second PCB board 30 close to each other so that the first connector 21 and the second connector 31 are connected, the operating member 400 can be used to assist the first connector 21 and the second connector 31 to connect. Specifically, as shown in part (a) of FIG. 4, the screw 300 can be used to pass through the first threaded hole 110 so that the screw rod is threadedly connected with the second threaded hole 210, and the screw 300 can be rotated to continuously screw into the second threaded hole 210, so that the nut of the screw 300 can be abutted against the first connector 100. Therefore, by rotating the screw 300, the first connector 100 can be driven to move toward the second connector 200, thereby driving the first connector 21 on the first PCB board 20 to be inserted into the second connector 31 on the second PCB board 30.

[0081] like Figure 1 As shown in FIG. 4( b), the operating member 400 includes a connecting end 410 and an operating end 420 that are coaxially arranged. The size and specification of the connecting end 410 are adapted to the first threaded hole 110, and can be threadedly connected to the first threaded hole 110. The operating end 420 is a disc-shaped structure, which can be convenient for the staff to rotate. Therefore, when it is necessary to operate the first connector 21 on the first PCB board 20 and the second connector 31 on the second PCB board 30 to connect and separate, the connecting end 410 of the operating member 400 can be threadedly connected to the first threaded hole 110 of the first connecting member 100. Therefore, the staff can operate and apply force to the first connecting member 100 and the first PCB board 20 through the operating end 420 of the operating member 400, so that the first connector 21 on the first PCB board 20 and the second connector 31 on the second PCB board 30 can be conveniently operated to connect and separate, thereby reducing the difficulty of operation for the staff. In addition, since the first threaded hole 110 is a through hole, after the connection end 410 of the operating member 400 is threadedly connected to the first threaded hole 110, the staff can also rotate the operating end 420 to make the end of the connection end 410 pass through the first threaded hole 110 and abut against the second connecting member 200, and drive the first connecting member 100 and the second connecting member 200 to separate by rotating the operating part, thereby separating the first connector 21 on the first PCB board 20 and the second connector 31 on the second PCB board 30. In this way, the difficulty of operation can be further reduced, and it is convenient for the staff to separate the first connector 21 and the second connector 31.
