AI Technical Summary
Existing spring-loaded contact fingers are prone to detachment of the moving contact during operation, are complicated to disassemble, and lack an effective linkage structure.
It adopts a static contact mounting cylinder and a quick installation mechanism, including a conductive core rod, conductive spring, tilting section, release section, extension rod, hook plate and hook ring. The hook plate is driven by the spring to tighten, achieving stable connection and convenient assembly and disassembly.
It achieves stability and convenient disassembly/reassembly of the conductive spring contact finger in the working state, avoids the moving contact from falling off, and simplifies the disassembly process.
