Embodiment Construction

[0016] In order to further prompt the present invention, it will be specifically described below in conjunction with accompanying drawings 1, 2, 3, 4, and 5.

[0017] The silver / copper / iron composite strip produced by the present invention actually has a four-layer structure. From top to bottom, the first layer is a silver metal oxide strip 1, and the second layer is a thinner pure silver strip 2 transition layer , the third layer is copper tape 3, and the fourth layer is iron tape 4. Wherein, the silver metal oxide strip 1 is a strip made of silver metal oxide, and the silver metal oxide includes silver tin oxide indium AgSno2 ino3, silver tin oxide AgSnO2, silver cadmium oxide AgCdO, etc. The copper strip 3 is a copper or copper alloy strip, and its process is as follows:

[0018] A. First, the silver strip 2 and the silver metal oxide strip 1 are surface cleaned to remove oil stains and oxides on the surface, and then the silver strip 2 and the silver metal oxide strip 1 a...

Abstract

This invention relates to compound materials technique field to process electricity probe and especially to one silver and copper and iron compound process method, which comprises the following steps: firstly grinding the silver metal oxidation and one film of pure silver materials for combination; then grinding the copper band and iron band to process this invention silver, copper and iron compound band.

Description

Technical field: [0001] The invention relates to the technical field of composite strips for preparing electrical contacts, in particular to a processing technology for silver / copper / iron composite strips. Background technique: [0002] Electric contacts are contact elements of electrical switches, thermostats and other instruments and meters. It is mainly responsible for connecting and breaking currents. It plays a decisive role in the safe operation of electrical appliances. Such as silver tin oxide AgSnO2, silver cadmium oxide AgCdO, etc.) materials are widely used in low-voltage electrical appliances due to their good resistance to electrical wear, welding resistance and electrical conductivity. With the wide application of electronic products, the demand for electrical contacts is also increasing. At present, there are electrical contacts on bimetallic composites made of silver and copper, but the welding of silver, copper and other materials in electrical contacts with...
