Description

Technical Field

[0001] The utility model relates to the technical field of welding wire clamps for coupler inner cover plates, in particular to a welding wire clamp for coupler inner cover plates capable of clamping multiple wires. Background Art

[0002] The current optocoupler wire welding devices are basically used to weld single optocoupler products, with extremely low production efficiency. In addition, the fixation during welding is mainly fixed by the pressure generated by the spring buckle. This fixing method can easily damage the product shell, causing the appearance defect rate to increase and affecting the appearance yield rate of the product. Moreover, after the spring buckle has been used for a period of time, the deformation of the spring will weaken, which will cause the clamping force to be unstable, affecting the stability and yield rate of the welding wire. The existing device still has some defects; for example;

[0003] The existing patent publication number is CN117484062A, which is a wire welding fixture for the inner cover of an optocoupler. When the technology is used, it includes a positioning cover, a welding pad, and a support pad. The positioning cover is provided with a positioning groove, and an extrusion boss is provided on one end face of the support pad. The welding pad is assembled at the bottom of the positioning groove, and the extrusion boss is assembled on the upper part of the positioning groove to press the welding surface of the welding pad to the bottom of the positioning groove. The bottom of the positioning groove is also evenly processed with a number of welding holes, and the other end face of the support pad is a plane. The present invention can clamp multiple optocoupler devices at the same time, meet the needs of mass production of optocouplers, improve production efficiency, and have higher welding stability, and will not damage the surface of the tube shell, thereby improving the overall yield of the product.
