Copper-intermediate silver contact for relay

Abstract

The invention discloses a copper-intermediate silver contact for a relay, and the contact provided by the invention consists of contacts, tail ends and intermediates, wherein the contacts and the tail ends are made of a silver material; and the intermediates are made of a copper material. The copper-intermediate silver contact for the relay disclosed by the invention has the characteristics of low cost, saved precious metal and the like while maintaining the original characteristics of high conductivity, low resistance, good contact and efficient conductance, thereby according with the requirements of low carbon, high efficiency and sustainable development to an industrial product nowadays.

Description

technical field [0001] A relay uses a copper intermediate silver contact. Background technique [0002] A relay is a component that selectively and frequently turns on or off the circuit according to the design requirements in the circuit. It is widely used in the electrical industry and is indispensable for a moment. [0003] The contact is the key part for the relay to connect or disconnect the circuit, and there are single-sided contacts and double-sided contacts. In the past, in order to meet the requirements of high conductivity, low resistance value, good contact and high-efficiency conduction, most of them were made of silver. [0004] Although the relay contacts made of silver have the characteristics of high conductivity, low resistance value, good contact and high-efficiency conduction, because silver is a rare and precious metal, there are problems of low mining and large usage both at home and abroad. Therefore, the all-silver contacts for relays have the disad...

AI Technical Summary

Problems solved by technology

[0004] Although the relay contacts made of silver have the characteristics of high conductivity, low resistance value, good contact and high-efficiency conduction, because silver is a rare and precious metal, there are problems of low mining and large usage both at home and abroad. Therefore, the all-silver contacts used in relays have the disadvantages of large amount of silver and high cost, which cannot meet the overall requirements of low-carbon, low-cost, economical, and simple in modern society.
