Abstract
The utility model relates to a duplex contact made of pure copper and a silver compound. The duplex contact comprises a silver compound composite layer (1) and a pure copper base body (2). The pure copper base body (2) is formed by a conical platform head and a cylindrical foot part. The thickness of the conical platform head is larger than that of the cylindrical foot part. The silver compound composite layer (1) is combined with one end of the conical platform head of the pure copper base body (2) and forms a pyramidal cone with the conical platform head. According to the utility model, silver zinc oxide and pure copper composite molding is employed, production cost is low, the duplex contact is environment-friendly and nontoxic and has good fusion welding resistance performance and good electrical wear resistance performance, an arcing time is short, breaking performance is high, large current shock resistance ability and arc erosion resistance ability are strong, and the duplex mainly is applied to middle and small capacity low voltage breakers for rated current lower than 200A.
Description
Technical field
The utility model relates to electronic devices and components and uses the field, contact, particularly relates to a kind of two 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 two composite contacts that adopt fine copper and silver compound; Fine copper and Ag-ZnO composite molding 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 two composite contacts that adopt fine copper and silver compound are provided; Comprise silver compound composite bed and fine copper matrix; Described fine copper matrix is made up of frustum head and cylindric foot; The thickness of described frustum head is greater than the thickness of cylindric foot, and the silver compound composite bed is compound in frustum head one end of fine copper matrix and forms the pyramid cone with the frustum head.
The thickness of described head composite bed is 0.2mm～0.6mm.
Described composite bed compound is to be processed by 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 two 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.
