AI Technical Summary

Technical Problem

Existing high-current female connectors have unstable structural designs and complex manufacturing processes. Traditional connectors are prone to poor contact between male and female terminals, resulting in poor contact, unstable limiting structure, loose assembly between the shell and female terminal, easy damage to contact springs, unreasonable layout, and unreasonable limiting structure design when transmitting high current. They are difficult to meet the stable working requirements in high-current environments.

Method used

A high-current female connector structure is designed. A first main body and a second main body are set on the female terminal to form a receiving cavity, and contact springs are set on both. After the male terminal is inserted, it is stopped by two sets of contact springs from both sides. The housing is installed on the outside of the female terminal. The main body has a limiting protrusion on the side near the housing to cooperate with the inner side of the housing. The arc-shaped protective rib abuts against the corner of the inner side wall of the housing. The housing has a clearance part on both sides that communicates with the receiving cavity. Multiple sets of connecting feet distribute the current load and optimize the current conduction path.

Benefits of technology

It enhances the tightness and stability of the male and female terminal connections, avoids loosening and poor contact, improves the reliability of current transmission and the stability of the structure, ensures the smoothness and stability of high current transmission, and meets the usage requirements in high current environments.
