AI Technical Summary

Technical Problem

Existing terminal connectors lack adequate dustproof structures at the interface, leading to easy dust accumulation, which affects the stability of circuit conduction. At the same time, the disassembly and assembly process is cumbersome, consuming time and manpower.

Method used

It adopts a dustproof shell and dustproof plate assembly, and the dustproof plate is slidably shielded by a limit ball and a limit spring. Combined with the quick fixing structure of the locking post and the rotating handle, it can be quickly assembled and disassembled.

Benefits of technology

It effectively prevents dust from entering the connector, improves the stability of circuit connections and equipment lifespan, and simplifies the disassembly and assembly process, thus improving the convenience of installation and maintenance.
