[0039] Figure 1 is a schematic structural diagram of an assist plug-in device, a first board 300, and a second board 200 according to an embodiment of the present utility model, Figure 2 is a schematic structural diagram of an assist plug-in device according to an embodiment of the present utility model, Figure 3Schematic structural diagram of the wrench assembly 20 in the plug assist device according to an embodiment of the present utility model when in the first position. Figure 4 Schematic structural diagram of the wrench assembly 20 in the plug assist device according to an embodiment of the present utility model when in the second position. As Figures 1 to 4 shown, in a specific embodiment, the plug assist device includes at least one plugging and unplugging device 100. Each plugging and unplugging device 100 includes a support 10 and a wrench assembly 20. The support 10 is installed at the side of the first board 300. The wrench assembly 20 is rotatably installed on the support 10. The wrench assembly 20 includes a handle portion 21 and at least one clamping portion 23. The clamping portion 23 is clamped with a limiting portion 210 provided on the second board 200. The wrench assembly 20 is configured to rotate when the handle portion 21 is operated, so that the clamping portion 23 drives the second board 200 to move, thereby enabling the second board 200 to be plugged into or separated from the first board 300. Here, the first board 300 includes a bottom plate 310 and a connector 320. The connector 320 is provided on the upper surface of the bottom plate 310. The second board 200 includes a gold finger 220 provided at the bottom of the second board 200. The gold finger 220 of the second board 200 is plugged into or separated from the connector 320 of the first board 300 under the action of the plug assist device, thereby realizing the plugging or separation of the second board 200 and the first board 300.

[0040] This embodiment does not require manual plugging and unplugging of the first board 300, is relatively easy to plug and unplug, and will not damage the board. In addition, the structure of the plug assist device in this embodiment is relatively simple. It can not only realize the plugging of the second board 200 and the first board 300, but also realize the separation of the second board 200 and the first board 300. Compared with the existing plug assist devices that can only realize separation, it has stronger practicability.

[0041] In some embodiments, the wrench assembly 20 includes two relatively arranged plate members 22. The two plate members 22 are respectively located on opposite sides of the second board 200, and at least one of the plate members 22 is provided with a clamping portion 23. Here, the clamping portions 23 can be respectively provided on the two plate members 22, or only on one of the plate members 22, which is specifically selected according to design requirements.

[0042] This embodiment is equivalent to using two plate members 22 to limit the second board 200, preventing the second board 200 from rotating around the X-axis during the plugging and unplugging process.

[0043] In some embodiments, at least one limiting portion 210 is provided on each side of the second board 200, and engaging portions 23 are provided on the two board members 22 respectively, and each engaging portion 23 corresponds to one limiting portion 210. Here, by providing the engaging portions 23 on the two board members 22 respectively, both opposite sides of the second board 200 can be stressed, so that the second board 200 can be inserted and removed in the vertical direction, further avoiding the second board 200 rotating around the X-axis during the insertion and removal process.

[0044] In some embodiments, the limiting portion 210 is in a shaft shape. The engaging portion 23 has an opening 232 and a chute 231 communicating with the opening 232. The limiting portion 210 of the second board 200 is arranged to enter from the opening 232 and slide along the chute 231 during the rotation of the wrench assembly 20. Here, the opening 232 and the chute 231 play a guiding role for the limiting portion 210, guiding the limiting portion 210 to enter the chute 231 from the opening 232. In addition, the gap defined between the two board members 22 plays a guiding role for the second board 200, and the second board 200 can be inserted between the two board members 22.

[0045] In some embodiments, the chute 231 is arc-shaped and is arranged to be always in a horizontal state with the tangent plane of the limiting portion 210 during the rotation of the wrench assembly 20. Refer to Figure 3 and Figure 4 , Figure 3 and Figure 4 The dotted lines in and represent the tangent lines. It can be seen that before and after the rotation of the wrench assembly 20, the tangent lines are both in a horizontal state. That is to say, during the rotation of the wrench assembly 20, the limiting portion 210 also slides along the arc-shaped chute 231, so as to ensure that the tangent plane of the limiting portion 210 and the chute 231 is always in a horizontal state. The structural design of the chute 231 needs to meet the requirement that no matter how the wrench assembly 20 rotates, the tangent plane should be in a horizontal state, which can ensure that the force received by the second board 200 during the insertion and removal process of the second board 200 is always along the Z-axis direction, that is, consistent with the movement direction of the second board 200, so as to realize the vertical insertion and removal of the second board 200.

[0046] In some embodiments, the distance between the pivot point of the wrench assembly 20 and the end of the handle portion 21 is a first distance, and the distance between the pivot point of the wrench assembly 20 and the limiting portion 210 is a second distance, and the first distance is greater than the second distance. This embodiment cleverly uses the lever principle to make the insertion and removal process more labor-saving.

[0047] Figure 5 is a schematic cross-sectional view of the wrench assembly 20 in the first position in the assistive plug-in device according to an embodiment of the present invention, Figure 6 is a schematic cross-sectional view of the wrench assembly 20 in the second position in the assistive plug-in device according to an embodiment of the present invention. AsFigure 5 and Figure 6 As shown in Figure 6 , in some embodiments, the top of the support 10 has an arc surface, and a first groove 122 and a second groove 121 are provided on the arc surface. The plugging and unplugging device 100 further includes a ball plunger 13. The ball plunger 13 is installed on the wrench assembly 20 and protrudes from the wrench assembly 20. The ball plunger 13 is arranged to be located in the first groove 122 when the wrench assembly 20 rotates to the first position where the first card 300 is plugged into the second card 200; and is located in the second groove 121 when the wrench assembly 20 rotates to the second position where the first card 300 is separated from the second card 200, so as to limit the wrench assembly 20. Specifically, when the first card 300 and the second card 200 are in the plugged state, the wrench assembly 20 is in the first position. Refer to Figure 3 , at this time, the ball plunger 13 is located in the first groove 122. If it is necessary to separate the first card 300 and the second card 200, the handle portion 21 is operated to make the wrench assembly 20 rotate. After the wrench assembly 20 rotates, the ball plunger 13 will pop out of the first groove 122 and move along the arc surface of the top of the support 10. When the wrench assembly 20 rotates to the second position, the second card 200 is separated from the first card 300. At this time, the ball plunger 13 enters the second groove 121, thereby realizing the locking of the wrench assembly 20. When the first card 300 and the second card 200 are in the separated state, the wrench assembly 20 is in the second position. Refer to Figure 4 , at this time, the ball plunger 13 is located in the second groove 121. If it is necessary to plug the second card 200 into the first card 300, the handle portion 21 is operated to make the wrench assembly 20 rotate in the reverse direction. After the wrench assembly 20 rotates, the ball plunger 13 will pop out of the second groove 121 and move along the arc surface of the top of the support 10. When the wrench assembly 20 rotates to the first position, the second card 200 is plugged into the first card 300. At this time, the ball plunger 13 re-enters the first groove 122, thereby realizing the locking of the wrench assembly 20.

[0048] Through the cooperation of the ball plunger 13, the first groove 122 and the second groove 121 in this embodiment, the locking of the wrench assembly 20 at two positions can be realized.

[0049] In some embodiments, the support 10 includes a horizontal portion 11 and a vertical portion 12. The horizontal portion 11 is arranged along the width direction of the first card 300. The vertical portion 12 is connected to the horizontal portion 11 and extends vertically. The top of the vertical portion 12 is rotatably connected to the wrench assembly 20. In this embodiment, the support 10 is designed in a T shape, which can improve the stability of the plug assist device during operation. Here, the first groove 122 and the second groove 121 are located at the top of the vertical portion 12. That is to say, the top of the vertical portion 12 has an arc surface.

[0050] In a preferred embodiment, the bottom of the vertical portion 12 has a limiting groove 111 extending along the width direction of the first circuit board 300. The limiting groove 111 is used to limit the first circuit board 300, so as to prevent the first circuit board 300 from moving when the second circuit board 200 is inserted into or removed from the first circuit board 300, which may affect the insertion and removal effect. Here, it is equivalent to using the horizontal portion 11 to press the bottom plate 310 of the first circuit board 300 to prevent displacement.

[0051] In some embodiments, the end of the handle portion 21 is provided with a bent portion 211 that bends outward, so as to improve the convenience of operating the handle portion 21.

[0052] In some embodiments, the number of the insertion and removal devices 100 is two, and the two insertion and removal devices 100 are respectively arranged on opposite sides of the first circuit board 300. This embodiment is equivalent to arranging an insertion and removal device 100 on both sides of the first circuit board 300, and the wrench assemblies 20 on both sides can be operated simultaneously, so as to insert and remove the two sides of the second circuit board 200 at the same time, which can improve the insertion and removal speed of the second circuit board 200 and improve the stability during the insertion and removal process of the second circuit board 200. When the insertion and removal aid has two insertion and removal devices 100, the limiting portion 210 of the second circuit board 200 can be arranged near the edge of the second circuit board 200. When the insertion and removal aid has only one insertion and removal device 100, the limiting portion 210 of the second circuit board 200 is arranged at the middle position of the second circuit board 200, and the wrench assembly 20 needs to be extended to the middle position of the second circuit board 200 to be engaged with the limiting portion 210, so as to realize the vertical insertion and removal of the second circuit board 200. This method requires extending the length of the handle portion 21 at the same time, which may occupy a relatively large space, and it is necessary to ensure that there are no other devices within the rotation range of the handle portion 21.

[0053] Specifically, referring to Figure 3 and Figure 4 , if it is necessary to remove the second circuit board 200 from the first circuit board 300, the handle portion 21 of the wrench assembly 20 on the left side is rotated counterclockwise, and the handle portion 21 of the wrench assembly 20 on the right side is rotated clockwise. That is to say, the rotation directions of the handle portions 21 on both sides are opposite, so as to apply forces to the second circuit board 200 at the same time and pull out the gold fingers 220 of the second circuit board 200 from the connector 320 of the first circuit board 300. If it is necessary to insert the gold fingers 220 of the second circuit board 200 into the connector 320 of the first circuit board 300, the handle portion 21 of the wrench assembly 20 on the left side is rotated clockwise, and the handle portion 21 of the wrench assembly 20 on the right side is rotated counterclockwise, so as to apply forces to the second circuit board 200 at the same time and insert the gold fingers 220 of the second circuit board 200 into the connector 320 of the first circuit board 300.

[0054] The plug-in assistant of this embodiment can achieve the vertical insertion of the second board 200 onto the first board 300 and the extraction of the vertically inserted second board 200 from the first board 300. In addition, after the rotation stroke of the wrench assembly 20 is in place, the locking of the wrench assembly 20 can be achieved through the ball plunger 13. The plug-in assistant of this embodiment has a simple structure and a small volume. Using this plug-in assistant can avoid hand injuries and prevent damage to the first board 300 and the second board 200.

[0055] Up to this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
