When heated, the 185℃ tin will melt, and the electrical connection columns on the original metal substrate will become crooked and tilted.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a tool for correcting an electrical connection column, comprising: The correction structure includes a correction frame, positioning holes are opened through the corners of the correction frame, and correction hole one is opened equidistantly through one side of the front side of the correction frame, correction hole two is opened through one side of the correction hole one, correction hole three is opened through the other side of the front side of the correction frame, and a cavity is opened in the middle of the correction frame.

[0005] Furthermore, the correction structure also includes a leakage hole, and the leakage hole is irregularly penetrated and opened on the front side of the correction frame.

[0006] Furthermore, it also includes an auxiliary positioning structure, which includes a bracket, a torsion spring is passed through the middle of both sides of the bracket, and a connecting frame is fixed on the inner side of the torsion spring, an auxiliary limit frame is fixed at one end of the connecting frame, and the auxiliary limit frame is in conflict with the outer surface of the electrical connecting column.

[0016] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] See also Figure 1-3 As shown, the present invention is an electrical connection column correction tool, comprising: The correction structure includes a correction frame 11, a positioning hole 12 is formed through the corners of the correction frame 11, and a correction hole 13 is formed through the front side of the correction frame 11 at an equidistant distance, a correction hole 2 14 is formed through the side of the correction hole 13, a correction hole 3 15 is formed through the other side of the front side of the correction frame 11, and a cavity 16 is formed in the middle of the correction frame 11; The correction frame 11 cooperates with the positioning hole 12 to limit the structure of the power module to be repaired. Correction hole 13, correction hole 2 14, and correction hole 3 15 are used to ensure that the electrical connection column does not tilt or move after the tin liquid melts during heating and repair. The cavity 16 ensures that the soldering iron can be effectively operated during the repair process to avoid other unnecessary components.

[0018] The correction structure further includes a leak hole 17, which is irregularly penetrated and opened on the front side of the correction frame 11; The leakage hole 17 ensures the heat dissipation required.

[0019] Working principle: After the power module and the correction frame 11 are connected and limited by the positioning hole 12, the electrical connection column is placed in the corresponding correction hole 13, correction hole 2 14 and correction hole 3 15 respectively. The electrical connection column can be limited after the tin liquid melts to ensure that it does not tilt or move. In the maintenance of the power module, the soldering iron can be effectively operated through the cavity 16, and the heat can be dissipated by using multiple leakage holes 17.

[0020] This solution ensures that the electrical connection column does not tilt or move after the molten tin liquid melts when the power module is heated for repair; and ensures that the soldering iron can be effectively operated during the repair process to avoid other unnecessary components; at the same time, since the entire repair work is carried out under heating conditions, in order not to affect heat dissipation, the device is designed with a leak hole 17, which is convenient to use and meets the needs.

[0021] See also Figure 1-3As shown, this embodiment is based on the above embodiment and further includes an auxiliary positioning structure, the auxiliary positioning structure includes a bracket 21, a torsion spring 23 is passed through the middle of both sides of the bracket 21, and a connecting frame 24 is fixed inside the torsion spring 23, an auxiliary limiting frame 25 is fixed at one end of the connecting frame 24, and the auxiliary limiting frame 25 is in conflict with the outer surface of the electrical connection column; The auxiliary positioning structure also includes a positioning column 22, one end of which is fixed to the outside of the torsion spring 23, and the other end of the positioning column 22 extends out of the openings opened in the middle of both sides of the bracket 21 and contacts the inner wall of the opening; The bracket 21 provides an installation environment, and the positioning column 22 is used to structurally limit the torsion spring 23. The torsion spring 23 provides the installation requirements of the connecting frame 24. The elastic force of the torsion spring 23 can meet the angle conversion requirements of the connecting frame 24, and cooperate with the auxiliary limit frame 25 to structurally limit the power module.

[0022] The connecting frame 24 is arranged in a U shape, and an arc-shaped groove is provided in the middle of one end of the auxiliary limiting frame 25 .

[0023] The connecting structure includes a locking block 31, which is symmetrically fixed to the upper part of both sides of the bracket 21 and fits the back of the correction frame 11, and a locking column 32 is penetrated through the middle of the locking block 31 and extends to the back of the correction frame 11, and a locking nut 33 is threaded on one end of the locking column 32; The locking block 31 cooperates with the locking column 32 to fix the structure of the bracket 21 after tightening the locking nut 33 .

[0024] Working principle: In the above-mentioned use of the positioning hole 12 to connect the correction frame 11 with the power module, after the power module structure passes through the positioning hole 12, it extends into the auxiliary limit frame 25. The damping force generated between the two can act on the torsion spring 23 to cause it to deform, that is, a group of connecting frames 24 are pushed outward and expanded to meet the positioning requirements. After the force is released, the torsion spring 23 restores the deformation, so that the auxiliary limit frame 25 applies a resistance force to part of the structure of the power module to ensure the stability of the structure.

[0025] This solution can ensure the structural stability of the power module and its adaptability to meet various needs.
