AI Technical Summary

Technical Problem

When responding to different current requirements, existing high-voltage connectors have difficulty matching connectors with overcurrent and structure. They have a long development cycle, high cost, and a small scope of application, so they cannot be used flexibly.

Method used

The modular design of a large current spring contact piece module structure is adopted. The number of spring contact pieces can be adjusted according to actual needs, so that the overcurrent of the contact connector between the terminals can be changed.

Benefits of technology

It realizes that the terminals can flexibly change the number of contact pieces according to actual current requirements, meet diversified current requirements, reduce development costs and cycles, expand the scope of application, and improve the simplicity of the structure, assembly convenience and safety and reliability.

Abstract

The present invention discloses a high-current wire spring contact piece module structure and a high-current terminal connection structure, the high-current wire spring contact piece module structure comprises a sheath and a first wire spring group and a second wire spring group which are clamped in the sheath and arranged in an upper and lower interval, the first wire spring group and the second wire spring group each comprise at least one wire spring contact piece, at least two protruding first contact points are arranged at intervals on one side of the first wire spring group facing the second wire spring group, at least two second contact points which correspond to the first contact points one by one on one side of the second wire spring group facing the first wire spring group are protruded, and a gap is arranged between the first contact point and the second contact point, and insertion ports are arranged at the positions corresponding to the gaps at both ends of the sheath. The present invention can flexibly change the overcurrent size between the terminals through modular structural design to meet the diversified needs of actual current, and also has the characteristics of simple structure, convenient assembly, safety and reliability, and wide application range.
