In order to improve the stability of electronic devices, reduce signal interference, improve production efficiency, and reduce the volume of electronic products, etc., wires are often soldered on the printed circuit board for electrical connection.
[0003] The through-hole assembly technology is one of the main technologies for soldering wires on a printed circuit board. It is to insert a wire into a through-hole existing on the printed circuit board and solder the joint. The advantage of this technology is that it can save the assembly space of the printed circuit board and the wire, and improve the soldering strength, enabling the electronic device to have better communication functions.
[0004] However, to achieve the assembly goal of the through-hole assembly technology, the wire needs to be passed through the printed circuit board and the joint needs to be soldered at the same time.

[0045] Please refer to Figure 2 . The base 10 has a shaft seat 11, a first limiting hole 12, and a limiting post placement groove 13. In this embodiment, the base 10 further has a bracket placement groove 14, and the shaft seat 11 is disposed in the bracket placement groove 14 of the base 10. The opening of the first limiting hole 12 is located on one side surface of the base 10, specifically, one side surface of the bracket placement groove 14. The opening of the limiting post placement groove 13 is disposed on the surface of the base 10. In this embodiment, the opening of the limiting post placement groove 13 is located on the top surface of the base 10. In other embodiments, the opening of the limiting post placement groove 13 is not limited thereto and may also be located on the side surface of the base 10.
[0046] Please refer to Figure 1 , Figure 2 and Figure 5 . The bracket 20 is connected to the base 10. In this embodiment, the bracket 20 is pivotally provided on the base 10 such that the bracket 20 can be rotated to be perpendicular or parallel to the base 10. In other embodiments, the bracket 20 can also be fixed to the base 10, and the connection manner between the bracket 20 and the base 10 is not limited thereto. The bracket 20 has an adjustment groove 21, a shaft hole 22, and a second limiting hole 23. The opening of the adjustment groove 21 is located on opposite two surfaces of the bracket 20, and the position of the shaft hole 22 corresponds to the shaft hole 22. The position of the second limiting hole 23 corresponds to the first limiting hole 12. When the bracket 20 is rotated perpendicular to the base 10, the second limiting hole 23 can be aligned with the first limiting hole 12. Please refer to Figure 5 . When the bracket 20 is parallel to the base 10, the limiting post 40 can be placed in the limiting post placement groove 13 for storage to prevent the loss of the limiting post 40.
[0047] Please refer to Figure 3。The rotating shaft 30 is passed through the shaft seat 11 and the shaft hole 22, enabling the bracket 20 to rotate about the rotating shaft 30 as the axis. The limiting post 40 can be selectively passed through the first limiting hole 12 and the second limiting hole 23. When the bracket 20 is perpendicular to the base 10, the second limiting hole 23 will align with the first limiting hole 12, and the limiting post 40 can be passed through the first limiting hole 12 and the second limiting hole 23, preventing the bracket 20 from rotating.
[0048] The positioning member 50 is connected to the bracket 20. Specifically, there is a clamping structure between the positioning member 50 and the bracket 20, enabling the positioning member 50 to be clamped onto the bracket 20. The positioning member 50 has a positioning groove 51, whose opening is located on the side of the positioning member 50 away from the base 10, and the printed circuit board B can be placed and fixed in the positioning groove 51.
[0049] Please refer to Figures 2 to 4 。The fixing member 60 is connected to the bracket 20 and has a first clamping portion 61, a second clamping portion 62, an adjusting member 63, and a wire limiting groove 64. The first clamping portion 61 is connected to the bracket 20 and has a pipe 611 and a sheet 612. The pipe 611 can be passed through the adjustment groove 21 of the bracket 20, and the sheet 612 is arranged on the side of the first clamping portion 61 close to the bracket 20. The second clamping portion 62 is pivotally provided on the first clamping portion 61. Specifically, the first clamping portion 61 and the second clamping portion 62 are connected by a hinge structure.
[0050] The adjusting member 63 can be locked onto the pipe 611 and jointly press the bracket 20 with the first clamping portion 61, enabling the fixing member 60 to be fixed on the bracket 20. When the user needs to adjust the distance between the fixing member 60 and the positioning member 50, the first clamping portion 61 and the second clamping portion 62 can be moved along the adjustment groove 21 of the bracket 20, and then the adjusting member 63 is locked onto the first clamping portion 61. At this time, the sheet 612 will adhere to one side surface of the bracket 20, thereby preventing the fixing member 60 from rotating. The wire limiting groove 64 is formed between the first clamping portion 61 and the second clamping portion 62, and the wire limiting groove 64 can be opened and closed by rotating the second clamping portion 62.
[0051] The wire 70 can be passed through the fixing member 60, and the core wire A is coated in the wire 70. When the printed circuit board B is placed in the positioning groove 51, the core wire A can be passed through the through hole B1 of the printed circuit board B. Specifically, in this embodiment, the wire 70 is clamped between the first clamping portion 61 and the second clamping portion 62 and arranged in the wire limiting groove 64. The wire 70 has at least one convex block 71, which can be clamped in the wire limiting groove 64. Thus, when the fixing member 60 moves, the wire 70 and the core wire A therein can be driven by the fixing member 60 to move.
[0052] When using the present utility model, the bracket 20 can be set to be perpendicular or parallel to the base 10 according to the user's needs. Please refer toFigure 1 If the bracket 20 is set perpendicular to the base 10, the limit post 40 can be inserted into the first limit hole 12 and the second limit hole 23, whereby the bracket 20 can be maintained perpendicular to the base 10 and cannot rotate. Please refer to Figure 5 If the bracket 20 is set parallel to the base 10, the bracket 20 will be attached to the base 10 at this time. Then, the printed circuit board B is placed in the positioning groove 51, and the core wire A is placed in the wire limiting groove 64. Finally, the first clamping portion 61 and the second clamping portion 62 are moved along the adjustment groove 21 of the bracket 20, thereby adjusting the distance between the core wire A and the printed circuit board B, so that the core wire A can pass through the through hole B1 of the printed circuit board B, and ensure the depth of the core wire A passing through the through hole B1 of the printed circuit board B. At this time, the user can solder the printed circuit board B and the core wire A.
[0053] The advantages of the present utility model are that through the arrangement of the positioning member 50 and the fixing member 60, the user does not need to hold the printed circuit board B and the wire 70, and through the arrangement of the adjusting member 63, the first clamping portion 61 and the adjusting groove 21, the wire 70 can also pass through the through hole B1 of the printed circuit board B, and there will be no situation of the wire 70 shifting or skewing. The present utility model fixes the printed circuit board B and the wire 70, and the user can hold the soldering iron and the solder wire to preheat the printed circuit board B, improve the quality and efficiency of soldering the printed circuit board B, and at the same time reduce the requirements for soldering skills.
