At present, the main materials for making junction boxes on the market are steel plates, aluminum alloys, plastics, etc. The junction boxes with steel plate structures are favored by the market due to their high corrosion resistance, high temperature resistance and strong rigid structure.

[0003] When processing these steel plate wiring boxes, manufacturers will use shearing, bending, stamping and other processing techniques to complete the required appearance structure, assemble the processed parts, and conduct overall inspection after assembly to ensure that the product quality meets the requirements. It is also necessary to inspect the electrical and mechanical properties of the product to ensure that the quality of the product is stable and reliable, including appearance inspection, electrical performance inspection, reliability test, etc., and the product can only be packaged and shipped after passing the inspection. However, when processing this type of steel plate wiring box, the movable connecting piece set in the box cannot be stamped and connected in the mold, and it needs to be installed manually on the preset claws. This not only reduces production efficiency, but also the manually installed movable connecting piece will be loose and tight, affecting the normal use of the product. Summary of the invention
