AI Technical Summary

Technical Problem

Existing metal shielded cable waterproof connectors are prone to problems during installation, such as incorrect shielding ring orientation, difficulty in controlling nut tightening, easy damage to sealing rings, and insufficient corrosion resistance, making it difficult to meet the high-performance requirements of mass production lines for new energy vehicles.

Method used

A foolproof metal shielded cable waterproof connector was designed, which uses a round nut made of aviation aluminum and a connector body made of brass. It combines a bending limit step, a clamping groove and a push rod and push block structure to ensure the correct installation of the shielding ring. The stability of the threaded connection is achieved by tightening the sleeve and clamping ball. Anti-loosening bumps are used to enhance the sealing effect, and chemical nickel plating is used to improve corrosion resistance.

Benefits of technology

This effectively avoids incorrect installation direction of the shielding ring, ensures accurate tightening, prevents loose threaded connections, enhances sealing and corrosion resistance, and extends product lifespan.

Abstract

This invention discloses a foolproof metal shielded cable waterproof connector, comprising a connector body, a flat nut on the outer side of one end of the connector body, a fixing ring and a connecting ring on the outer side of the connector body, a square sealing groove on one end face of the connecting ring, an elliptical sealing ring in the square sealing groove, a foolproof shielding ring in the inner hole of the connector body, a bending spring clip claw on the inner ring of the foolproof shielding ring, a conductive contact boss on the outer ring of the foolproof shielding ring, an abutment block on one end of the inner side of the foolproof shielding ring, a bending limiting step between two adjacent bending spring clip claws, a sealing bushing on the top of the foolproof shielding ring, and a round nut on the outer side of the other end of the connector body, a tightening sleeve on the outer side of both the round nut and the flat nut, and a push groove on the inner side of both the round nut and the flat nut. This invention achieves a high-performance foolproof effect with anti-reverse installation of the shielding ring, controllable tightening of the nut, strong end face sealing adaptability, excellent salt spray corrosion resistance, and threaded connection locking to prevent loosening.
