AI Technical Summary

Technical Problem

The existing spring-loaded mounting method in circular terminals results in high switching resistance, and traditional processing methods are inefficient, costly, and unstable.

Method used

A novel circular stretchable terminal is designed, which is formed by stretching copper strip into a socket body. A contact spring and a limiting structure are provided in the socket body. The contact spring is welded and fixed to the socket body. The form of torsion spring or leaf spring is adopted to reduce fretting friction and improve stability and current carrying capacity.

Benefits of technology

It reduces the switching resistance, improves the terminal current carrying capacity, simplifies the production process, reduces waste, and increases production efficiency, making it suitable for mass production.
