Abstract
The utility model relates to a three-composite contact made of pure copper and a silver compound. The three-composite contact comprises a pure copper base body, a silver compound composite layer and an opposite composite layer, wherein the pure copper base body consists of a cylindrical head and a cylindrical foot; the thickness of the cylindrical head is greater than that of the cylindrical foot; the silver compound composite layer is composited at one end of the cylindrical head of the pure copper base body; the opposite composite layer is composited at one end of the cylindrical foot of the pure copper base body; and a composite layer compound is silver zinc oxide. The three-composite contact is formed by compositing the silver zinc oxide and the pure copper, and is low in production cost, environment-friendly, non-toxic, high in fusion welding resistance, high in electrical wear resistance, short in arcing time, high in breaking performance, high in large-current impact resistance, high in arc erosion resistance, and mainly applicable to medium-and small-capacity low-voltage breakers with rated current of below 200 A.
Description
Technical field
The utility model relates to electronic devices and components and uses the field, contact, particularly relates to a kind of three composite contacts that adopt fine copper and silver compound.
Background technology
The contact is an element commonly used in the various electronic devices and components, and very high to its performance demands though its volume is little, composite contact has wide range of applications and usually uses precious metal material, generally adopts manual rivet and automatic riveting.Be composite contact in the market with fine silver; But fine silver intensity is low, hardness is low, resistance fusion welding and anti-electrical arc erosion performance are low; And consumption is big, cost an arm and a leg, and production cost is high, can only be applied in radio, communication with fields such as microswitch and little electric current electrical equipment.
The utility model content
The utility model technical problem to be solved provides a kind of three composite contacts that adopt fine copper and silver compound; Fine copper and the composite molding of Ag-ZnO material have been adopted; Production cost is low, and environment-protecting asepsis has anti-melting welding, anti-electrical wear property is good; Arcing time is short, and interrupting performance height, Chinese People's Anti-Japanese Military and Political College's rush of current ability and anti electric arc corrosion ability are strong.
The utility model solves the technical scheme that its technical problem adopted: a kind of three composite contacts that adopt fine copper and silver compound are provided; Comprise fine copper matrix, silver compound composite bed and offside composite bed; Described fine copper matrix is made up of cylindric head and cylindric foot; The thickness of described cylindric head is greater than the thickness of cylindric foot; The silver compound composite bed is compound in cylindric head one end of fine copper matrix, and said offside composite bed is compound in cylindric foot one end of fine copper matrix.
The thickness of described head composite bed is 0.2mm～0.6mm, the thickness 0.2mm～0.6mm of described foot composite bed.
Described composite bed compound is Ag-ZnO (AgZnO).
Ag-ZnO (AgZnO) environment-protecting asepsis has anti-melting welding, anti-electrical wear property is good, and the arcing time is short, the characteristics that interrupting performance is high, Chinese People's Anti-Japanese Military and Political College's rush of current ability is strong.Compare with Agcdo (AgCdO) contact material and to have better resistance fusion welding, under the breaking current condition of 3000～5000A, have better anti electric arc corrosion ability.
Beneficial effect
The utility model relates to provides a kind of three composite contacts that adopt fine copper and silver compound; Adopted fine copper and the composite molding of Ag-ZnO material, production cost is low, environment-protecting asepsis; Have anti-melting welding, anti-electrical wear property is good; Arcing time is short, and interrupting performance is high, Chinese People's Anti-Japanese Military and Political College's rush of current ability and anti electric arc corrosion ability are strong, be mainly used in rated current at 200A with interior medium and small capacity low pressure circuit breaker.
