AI Technical Summary

Technical Problem

The existing socket has a large contact area between the copper contacts and the plug structure, which makes it difficult to pull out during insertion and removal, affecting the feel of insertion and removal.

Method used

A socket structure is designed, in which a slot is formed by bending a copper sheet body, and the plug and the curved part are set at an angle. The insertion and removal path is optimized by combining the surface contact and point contact of the flat part and the curved part. Reinforcing ribs are set on the socket structure to enhance the structural strength and conductivity.

Benefits of technology

It improves the stability and conductivity of the connection, reduces insertion and extraction resistance, extends service life, ensures the stability of current transmission and the convenience of insertion and extraction operations, and enhances the user experience.

Abstract

A socket sleeve structure for use with copper contacts in a receptacle features an angled design where the curved portion away from the terminal connection is tilted towards the flat portion away from the terminal connection. This design allows the plug to form a good elastic contact with the curved portion after insertion, increasing the stability and conductivity of the connection. Furthermore, this tilted design facilitates smooth sliding of the plug during insertion and removal, reducing resistance and extending the socket's lifespan. Simultaneously, the surface contact between the flat portion and the plug ensures stable current transmission, while the point or line contact between the curved portion and the plug provides additional elastic support, making the entire connection structure more reliable. This sleeve structure design also reduces the contact area during plug insertion, preventing misalignment or jamming, and allows for smooth removal of the plug from the slot, improving the ease of insertion and removal and enhancing the feel of the plug.
