[0043] Referring to Figure 1 and Figure 2 , an assembly jig for assembling a circuit board and a connector is provided in an embodiment of this application, hereinafter simply referred to as the assembly jig 100. The assembly jig 100 includes two positioning members 10, a gasket 20, a guide rail 30 and a mounting member 40. The two positioning members 10 are arranged oppositely. With reference to Figure 3 , when observing along the first direction X defined by the two positioning members 10, the positioning members 10 are provided with a plurality of positioning through holes 101 arranged horizontally. Each positioning through hole 101 is used for one terminal 140 on the circuit board 120 to pass through, so as to be able to correct the orientation direction of the terminal 140, and further facilitate improving the simplicity of inserting the terminal 140 into the connector 110 (with reference to Figure 5 ). Referring to Figures 1 to 3, the gasket 20 abuts between the two positioning members 10, such that a plurality of positioning through holes 101 of one positioning member 10 are disposed on one side of the gasket 20, and a plurality of positioning through holes 101 of the other positioning member 10 are disposed on the other side of the gasket 20. Exemplarily, the gasket 20 can be one of a metal part or a plastic part. The gasket 20 can stabilize the distance between the positioning through holes 101 of the two positioning members 10, thereby ensuring the docking consistency between the terminal 140 and the connector 110, and further facilitating the smooth insertion of the terminal 140 into the corresponding hole of the connector 110. The guide rail 30 is disposed parallel to the passing direction of the positioning through holes 101. Exemplarily, the guide rail 30 can be disposed perpendicular to the first direction X. The mounting member 40 includes a connecting arm 41 and a mounting arm 42 connected at an angle. Exemplarily, the mounting arm 42 can be disposed perpendicular to the connecting arm 41, such that a certain point of the mounting arm 42 can be moved to a specified position with a relatively small stroke of the connecting arm 41. The connecting arm 41 is slidably connected to the guide rail 30, such that the mounting arm 42 moves closer to or away from the positioning through holes 101. Exemplarily, the connecting arm 41 can be provided with a connecting groove, the guide rail 30 is disposed in the connecting groove and is provided with a receiving groove, and the groove wall of the connecting groove can be provided with a boss, and the boss is disposed in the receiving groove, such that the connecting arm 41 can move in a direction restricted by the guide rail 30 and it is not easy for the two to disengage. In another embodiment, a corresponding connecting groove can be provided at the top of the guide rail 30, and the connecting arm 41 can be disposed in the connecting groove to achieve the slidable connection between the two. It can be understood that the slidable connection between the connecting arm 41 and the guide rail 30 can be achieved in various ways. The mounting arm 42 is provided with a mounting hole 420, and the mounting hole 420 is disposed opposite to the positioning through holes 101 for mounting the connector 110. Exemplarily, the mounting hole 420 can be a blind hole or a through hole.

[0044] In specific use, the mounting member 40 can be moved in a direction away from the positioning through holes 101, thereby fixing the connector 110 in the mounting hole 420, such that the hole of the connector 110 is disposed opposite to the positioning through holes 101. The two rows of terminals 140 of the folded circuit board 120 are inserted into the positioning through holes 101 one by one from the side facing away from the mounting arm 42, and then moving the mounting member 40 can achieve the docking of the terminals 140 to the corresponding holes of the connector 110. The circuit board 120 can be fixed by an auxiliary tool or by hand.

[0045] In the present application, the gasket 20 abuts between two positioning members 10, such that the positioning through holes 101 of different positioning members 10 are arranged at a fixed distance on opposite sides of the gasket 20, thereby enabling the spacing of the positioning through holes 101 in different rows to be stabilized. Furthermore, this facilitates stabilizing the spacing between the terminals 140 in different rows of the folded circuit board 120, and thus is conducive to improving the smoothness of inserting the terminals 140 into the corresponding holes of the connector 110. Additionally, each positioning through hole 101 is used for a terminal 140 of the circuit board 120 to pass through, and the positioning through hole 101 can correct the bending degree of the terminal 140, thereby facilitating reducing the difficulty of connecting the terminal 140 to the connector 110. Moreover, the mounting member 40 for mounting the connector 110 is slidably connected to the guide rail 30, such that the mounting member 40 can be oriented to approach the positioning through hole 101, thereby facilitating the oriented docking of the connector 110 and the terminal 140 and avoiding the process of repeatedly docking and correcting the terminal 140 and the connector 110. Therefore, the assembly jig 100 provided in the present application is also conducive to improving the assembly efficiency.

[0046] In some embodiments, a convex block 421 is provided on a hole wall of the mounting hole 420. During specific use, the convex block 421 can be arranged in a groove on one end face of the connector 110, thereby preventing the connector 110 from being installed reversely, and thus facilitating improving the anti-fooling function of the mounting member 40.

[0047] In some embodiments, with reference to Figure 4 , convex blocks 421 are provided on both hole walls of the mounting hole 420 that are oppositely arranged. The number of convex blocks 421 connected to different hole walls is different, or the two hole walls are provided with the same number of convex blocks 421, and the layout positions of the convex blocks 421 on different hole walls are different, that is, the convex blocks 421 on different hole walls can be arranged in a staggered manner or partially staggered manner, such that the connector 110 can only be fixed in the mounting hole 420 in a specific manner, and further, the mounting member 40 has an anti-fooling function, thereby being able to avoid the situation where the terminal 140 is inserted in a mismatched manner due to accidentally installing the connector 110 reversely. Therefore, the mounting member 40 with an anti-fooling function is also conducive to further improving the assembly efficiency of the assembly jig 100.

[0048] In some embodiments, with reference to Figure 2 and Figure 3, the assembly fixture 100 further includes at least two first positioning posts 50 (two first positioning posts 50 are shown in the figure) and a second positioning post 51. The at least two first positioning posts 50 are arranged along a second direction Y defined by a plurality of positioning through holes 101. Exemplarily, the at least two first positioning posts 50 can be arranged at intervals, so that the limiting effect with the same effect can be achieved by a smaller number of first positioning posts 50. The second positioning post 51 is arranged at intervals on one side of a first positioning post 50 close to the mounting arm 42. Both the first positioning post 50 and the second positioning post 51 protrude from the same positioning member 10 relative to the other positioning member 10. Exemplarily, the positioning member 10 can be provided with fixing holes, and both the first positioning post 50 and the second positioning post 51 can be fixed in the fixing holes to install the two. When observed along the second direction Y, both the first positioning post 50 and the second positioning post 51 are arranged beside the other positioning member 10, so as to facilitate observing the positioning effect of the positioning posts. When observed along the second direction Y, the gasket 20 is provided with a groove 201, and the second positioning post 51 is arranged in the groove 201, so that one side wall of the groove 201 is arranged between the spaced first positioning post 50 and the second positioning post 51, and the first positioning post 50 abuts against the side end of the gasket 20. The cooperation of the first positioning post 50 and the second positioning post 51 is beneficial to improving the positioning accuracy of the gasket 20.

[0049] In some embodiments, the gasket 20 includes a first part 21 and a second part 22. The first part 21 abuts between the two positioning members 10. The first part 21 is further provided with a groove 201, and the first positioning post 50 abuts against the side end of the first part 21. The second part 22 protrudes from the first part 21 relative to the mounting arm 42 at an end away from the groove 201. Exemplarily, the first part 21 and the second part 22 can be integrally formed, and the second part 22 protrudes from the positioning member 10. The structure of the gasket 20 facilitates adjusting the installation position.

[0050] In some embodiments, the end face of the first part 21 facing away from the mounting arm 42 has an adjacent first area 211 and a second area 212. The first area 211 is closer to the second part 22. The second area 212 is recessed relative to the first area 211 to form a stepped structure, and the first positioning post 50 abuts against the second area 212. The shape of the first part 21 is beneficial to ensuring the strength of the gasket 20 while also being beneficial to increasing the avoidance space of the gasket 20, thereby reducing the structural limitation of the gasket 20 on the circuit board 120, and further being beneficial to improving the adaptability of the assembly fixture 100.

[0051] In some embodiments, refer to Figure 1 and Figure 2, the assembly jig 100 also includes a bracket 60, the bracket 60 includes a first frame portion 61 and a second frame portion 62, a positioning member 10 is installed on the first frame portion 61, and another positioning member 10 is installed on the second frame portion 62. For example, one positioning member 10 can be embedded in the first frame portion 61 to be exposed on the surface of the first frame portion 61 relative to the second frame portion 62, and the other positioning member 10 can be arranged to protrude from the second frame portion 62 relative to the first frame portion 61. It can be understood that the installation conditions of the positioning members 10 connected to the first frame portion 61 and the second frame portion 62 can be opposite. Or both positioning members 10 can be installed in an embedded or protruding manner. For example, the positioning member 10 can be installed by screw fixing. The second frame portion 62 and the first frame portion 61 are used to cooperate to form a limiting gap, and the circuit board 120 is limited in the limiting gap, so that the circuit board 120 can be fixed, so that the circuit board 120 does not need to be manually fixed during docking. Observing along the second direction Y defined by the plurality of positioning through holes 101, the second frame portion 62 includes a first end 621 and a second end 622 that are arranged opposite to each other, and the first end 621 is rotatably connected to the first frame portion 61. The first frame portion 61 and the second frame portion 62 that can be relatively opened and closed facilitate the installation of the circuit board 120, and the fixing effect of the limiting gap makes it unnecessary to manually fix the circuit board, thereby facilitating the use convenience of the assembly jig 100.

[0052] In some embodiments, the second frame portion 62 includes a stacked first frame body 623 and a second frame body 624, and the first frame body 623 is rotatably connected to the first frame portion 61, that is, the second frame body 624 includes a first end 621 and a second end 622 arranged opposite to each other, and the second frame body 624 is protruded from a part of the end surface of the first frame body 623 relative to the first frame portion 61 to form a limiting gap with the first frame portion 61, so that the limiting gap can avoid the bending and overlapping area of ​​the circuit board 120.

[0053] In some embodiments, the bracket 60 further includes a third frame portion 63 and at least two support columns 64 (four support columns 64 are shown in the figure) arranged at intervals. The third frame portion 63 is arranged at intervals on the side of the first frame portion 61 away from the second frame portion 62, and the guide rail 30 is installed on the third frame portion 63.

The support column 64 is connected between the first frame portion 61 and the third frame portion 63, and the guide rail 30 is arranged in a space defined by the support column 64, the first frame portion 61 and the third frame portion 63. The integration of the bracket 60 is conducive to improving the integration of the assembly jig 100, thereby facilitating overall movement.

[0054] In some embodiments, the assembly fixture 100 further includes a handle 70 and a catch 80. The handle 70 is rotatably and openably connected to the second end 622. The catch 80 includes an elastic arm 81 and a hook portion 82 that are connected to each other. The elastic arm 81 protrudes from the handle 70 relative to the first frame portion 61, and the hook portion 82 is disposed relative to the second end 622. The hook portion 82 is used to abut against the end face of the first frame portion 61 facing away from the second frame portion 62, so as to stabilize the size of the limiting gap between the first frame portion 61 and the second frame portion 62, thereby facilitating the improvement of the limiting stability of the bracket 60. The state of the catch 80 being engaged and disengaged can be changed by rotating the handle 70.

[0055] In some embodiments, the handle 70 is provided with a grip hole, so as to facilitate gripping the handle 70 to rotate the second frame portion 62.

[0056] In some embodiments, the second frame portion 62 is respectively rotatably connected to the first frame portion 61 and the handle 70 through a hinge structure 90. The hinge structure 90 realizes the rotatable connection, making the structure of the assembly fixture 100 relatively simple and facilitating disassembly and assembly at the same time. Exemplarily, the hinge structure 90 connected between the second frame portion 62 and the handle 70 can also be a hinge device including a torsion spring, so as to realize the automatic reset of the handle 70.

[0057] In other embodiments, the second frame portion 62 can be rotatably connected to the first frame portion 61 and the handle 70 by means of universal balls or hinges.

[0058] In some embodiments, referring to Figure 1 and Figure 4 , the assembly fixture 100 further includes a first limiting member 91 and a second limiting member 92. The first limiting member 91 protrudes from the first frame portion 61 relative to the second frame portion 62. The first limiting member 91 is disposed on the side of the hinge structure 90 away from the handle 70 near the first end 621. The first limiting member 91 is used to limit the rotation angle of the second frame portion 62. The second limiting member 92 protrudes from the second end 622 away from the first end 621.
