Description

Technical Field

[0001] This utility model relates to the positioning and disassembly of PCB plug-in solder feet, specifically a bushing structure that facilitates the positioning and disassembly of PCB plug-in solder feet. Background Technology

[0002] In existing technology, the transformer and PCB assembly structure design involves soldering after the transformer and PCB are assembled. During assembly, the transformer has multiple solder pads and the mounting holes have small gaps, making positioning difficult. Furthermore, if these solder pads are misaligned, positioning and insertion become even more challenging, leading to low assembly efficiency. Additionally, the small gaps between the solder pads and mounting holes result in a tight fit after soldering, making maintenance difficult and increasing disassembly and assembly time and costs. Therefore, a bushing structure that facilitates the positioning and disassembly of PCB component solder pads is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a bushing structure that facilitates the positioning and disassembly of PCB plug-in solder feet in order to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bushing structure that facilitates the positioning and disassembly of PCB plug-in solder feet, characterized by including a PCB board, several assembly holes on the PCB board corresponding to several plug-in solder feet, and a copper bushing installed in the assembly holes and fitted onto the plug-in solder feet, wherein the diameter of the assembly holes is larger than the diameter of the plug-in solder feet.

[0005] More preferably, the copper bushing is provided with a limiting platform that limits its installation on the assembly hole and a through hole through which the plug-in solder feet can pass.

[0006] In a further preferred embodiment, the copper bushing is also provided with a guide surface that guides it as it is installed into the mounting hole.

[0007] The beneficial effects of this utility model are as follows: By setting the diameter of the mounting hole on the PCB to be larger than the diameter of the plug-in solder pad, the gap between the solder pad and the mounting hole is increased, which facilitates the positioning and assembly of the plug-in on the PCB board. Furthermore, by setting the copper bushing, after the plug-in solder pad is assembled with the PCB board, the copper bushing is fitted onto the plug-in solder pad and installed at the mounting hole. After soldering, it serves as a conductive component between the solder pad and the PCB board. This facilitates the positioning and assembly of the plug-in solder pad with the PCB board, improves assembly efficiency, reduces labor costs, and increases production efficiency.

[0008] Furthermore, by using the copper bushing, when the board needs to be repaired and disassembled later, you only need to heat the copper bushing to melt the solder and then remove the copper bushing from the top. At this time, the mounting holes and plug-in solder feet on the PCB board are disconnected and the gap is large, making it easy to disassemble. Attached Figure Description

[0013] The following description, in conjunction with the accompanying drawings, further illustrates the bushing structure of this utility model that facilitates the positioning and disassembly of PCB plug-in solder feet.

[0014] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] See Figures 1-3 As shown, a bushing structure that facilitates the positioning and disassembly of PCB plug-in solder feet is characterized by including a PCB board 1, a plurality of mounting holes 2 on the PCB board 1 corresponding to a plurality of plug-in solder feet 3, and a copper bushing 4 installed in the mounting holes 2 and fitted on the plug-in solder feet 3, wherein the diameter of the mounting holes 2 is larger than the diameter of the plug-in solder feet 3.

[0017] By setting the mounting hole 2 on the PCB with a diameter larger than that of the plug-in solder pad 3, the gap between the solder pad and the mounting hole 2 is increased, which facilitates the positioning and assembly of the plug-in onto the PCB board 1. Then, by setting the copper bushing 4, after the plug-in solder pad 3 is assembled with the PCB board 1, the copper bushing 4 is put on the plug-in solder pad 3 and installed at the mounting hole 2. After soldering, it serves as a conductive component between the solder pad and the PCB board 1. This facilitates the positioning and assembly of the plug-in solder pad 3 with the PCB board 1, improves assembly efficiency, reduces labor costs, and improves production efficiency.

[0018] Furthermore, with the copper bushing 4 in place, when the board needs to be repaired and disassembled later, the copper bushing 4 can be heated to melt the solder and then removed from the top. At this time, the mounting hole 2 on the PCB board 1 and the plug-in solder foot 3 are disconnected with a large gap, making it easy to disassemble.

[0019] In one embodiment, the copper bushing 4 is provided with a limiting platform 41 that limits its installation on the mounting hole 2 and a through hole 42 through which the plug-in solder foot 3 can pass; the limiting platform 41 limits the installation of the copper bushing 4 on the PCB board 1, and the through hole 42 allows the copper bushing 4 to be fitted onto the plug-in solder foot 3 through the through hole 42.

[0020] In one embodiment, the copper bushing 4 is also provided with a guide surface 43 to guide it into the mounting hole 2. The guide surface 43 facilitates the insertion of the lower end of the copper bushing 4 into the mounting hole 2 of the PCB board 1, avoiding interference that could affect the installation efficiency.

[0021] When using this utility model: when connecting the plug-in to the PCB board 1, insert the solder feet on the plug-in into the mounting holes 2 of the PCB board 1, or align the PCB board 1 with the solder feet of the plug-in and then fix the PCB board 1 and the plug-in with screws, etc. Then, sequentially put several copper bushings 4 through the through holes 42 onto the solder feet and insert them into the mounting holes 2 to fill the gap between the PCB board 1 and the solder feet 3 of the plug-in. Then, the copper bushings 4 can be welded and fixed on the PCB board 1, and the solder feet are welded to the copper bushings 4.

[0022] When board disassembly and repair are required, first heat the copper bushing 4 to melt the solder, so that the solder between the copper bushing 4 and the PCB board 1 and between the copper bushing 4 and the solder pads melts. Then, the melted solder can be removed with a desoldering pump. Then, remove the copper bushing 4 from the top. After the copper bushing 4 is removed, the gap between the solder pads and the mounting holes 2 on the PCB board 1 is large, and the two are separated and not connected. At this time, the connection between the PCB board 1 and the plug-in can be directly disconnected and the PCB board 1 can be removed directly.

[0023] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
