[0002] With the continuous development of science and technology, the demand for space utilization of board end connector is increasing, and many products are increasingly pursuing thinness and miniaturization.

[0003] The existing method is generally to invert the connector in the fixed hole (the main body of the terminal is arranged at the position of the PCB away from the insertion end), to realize the reduction of the use space on the board end, and also to ensure the stability of installation.

[0004] However, when the connector is circular / cylindrical, due to the shape characteristics of the circular female end, there is a lack of clear positioning reference during welding with the board end, so it is difficult to ensure the stability of the welding operation, and therefore, during the welding process, the problems of miswelding or false welding are likely to occur, and it is difficult to ensure the consistency of production, affecting the quality of the product. SUMMARY

[0005] The main purpose of the utility model is to provide an anti-rotation circular female end connector for welding plate, which is designed to set an anti-rotation structure to ensure the positioning of the female end and the PCB, and to realize consistent welding and prevent mistaken welding.

[0006] To achieve the above-mentioned purpose, the utility model provides an anti-rotation circular female end connector for welding plate, comprising:

[0007] The female terminal is a hollow cylindrical body, and the wall surface of the female terminal is provided with a radially extending positioning part;

[0008] The welding leg is arranged at the front end position of the female terminal and extends outward.

[0009] In actual design, the wall surface of the female terminal is provided with a positioning part, which can be an inner concave structure or an outer convex structure, and the through hole of the PCB is provided with a limiting structure matched with the positioning part. The positioning part can avoid the rotation of the female terminal, thereby ensuring the relative arrangement of the welding leg and the welding position of the PCB, and ensuring the consistency of the positioning reference and the stability of the welding.

[0010] When the positioning part is clamped into the limiting structure of the PCB, the welding leg of the female end is aligned with the welding position of the board end, and can be directly welded. BRIEF DESCRIPTION OF DRAWINGS
