an electrical connector

Abstract

The invention belongs to the field of electrical and signal connection technologies, and particularly relates to an electrical connector. The electrical connector comprises an inner conductor, an installation board and a shell body, and is characterized in that: the inner conductor is made of copper alloy, and is composed of the following components by weight: 0.012 to 0.043% of cobalt, 0.034 to 0.045% of vanadium, 0.038 to 0.045% of manganese, 0.078 to 0.088% of zinc, 0.12 to 0.20% of silicon, 0.020 to 0.032% of samarium, 0.032 to 0.042% of titanium, 0.022 to 0.034% of tin, 0.045 to 0.056% of nickel, and the balance being copper. The inner conductor adopted by the electrical connector has excellent conductive performance and high strength, the tensile strength thereof reaches 610 to 635Mpa, the conductivity ranges from 81 to 83.5% IACS, and the softening-resistant temperature reaches 455 to 468 DEG C.

Description

technical field [0001] The invention belongs to the technical field of electrical and signal connection, and in particular relates to an electrical connector. Background technique [0002] Electrical connectors are widely used in construction machinery, tobacco machinery, textile machinery, printing machinery, electric locomotives and petrochemical electrical equipment that require electrical and signal connections. At present, electrical connectors are mainly hermetically sealed and welded, and are mainly composed of an inner conductor, a mounting plate and a housing. Generally, a layer of metal film, such as gold, nickel, tin, etc., will be plated on the outside of the inner conductor, and the metal film can only reduce its surface resistance value, and it will still cause excessive temperature rise when large current is transmitted. In the prior art, the shell is mostly made of alloy, and the weight of the alloy is heavy, so the application of the electrical connector in...

AI Technical Summary

Problems solved by technology

Generally, a layer of metal film, such as gold, nickel, tin, etc., is plated on the outside of the inner conductor, and the metal film can only reduce its surface resistance value, and it will still cause excessive temperature rise when large current is transmitted.

In the prior art, the shell is mostly made of alloy, and the weight of the alloy is large, such as aerospace and other fields, the application of this electrical connector will be limited

The inner conductor is generally made of bronze, and after it is sealed with the mounting board, it is difficult to maintain sufficient rigidity to support high-strength plug-in connections.
