Abstract
The utility model relates to a triplex contact adopting a pure copper and a silver compound. The contact includes a pure-copper substrate (2), a silver-compound composite layer (1) and a contralateral composite layer (3). The pure-copper substrate (2) includes a cone-shaped head part and a cylindrical foot part. Thickness of the cone-shaped head part is larger than thickness of the cylindrical foot part. The silver-compound composite layer (1) is composited at one end of the cone-shaped head part and forms a cone together with the cone-shaped head part of the pure-copper substrate (2). The contralateral composite layer (3) is composited at one end of the cylindrical foot part of the pure-copper substrate (2). The triplex contact adopting the pure copper and the silver compound is composite formed by silver zinc oxide and the pure copper so that the contact is low in manufacturing cost, environmental-friendly and non-toxic, great in welding resistance and electrical-wear resistance performance, short in arc time, great in breaking performance and high in large-current shock resistance capability and arc erosion resistance capability. The contact is mainly used in low-voltage circuit breakers of medium and small capacity with rated current no larger 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 three composite contacts that adopt fine copper and silver compound.
Background technology
Contact is element commonly used in various electronic devices and components, though its volume is little, very high to the requirement of its performance, composite contact has wide range of applications and usually uses precious metal material, generally adopts manual rivet and automatic riveting.The composite contact with fine silver in the market, but fine silver intensity is low, hardness is low, resistance fusion welding and anti-electrical arc erosion performance low, and consumption is large, expensive, 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
Technical problem to be solved in the utility model is to provide a kind of three composite contacts that adopt fine copper and silver compound, fine copper and the moulding of Ag-ZnO Material cladding have been adopted, production cost is low, environment-protecting asepsis, have anti-melting welding, anti-electrical wear is good, arcing time is short, interrupting performance is high, Chinese People's Anti-Japanese Military and Political College's rush of current ability and the anti electric arc corrosion ability strong.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of three composite contacts that adopt fine copper and silver compound are provided, comprise the fine copper matrix, silver compound composite bed and offside composite bed, described fine copper matrix is comprised of frustum head and cylindric foot, the thickness of described frustum head is greater than the thickness of cylindric foot, described silver compound composite bed be compound in the fine copper matrix the frustum head an end and together with the frustum head of fine copper matrix, form cone, described offside composite bed is compound in cylindric foot one end of fine copper matrix.
The thickness of described silver compound composite bed is 0.2mm～0.6mm, the thickness 0.2mm～0.6mm of described offside composite bed.
Described silver compound composite bed and offside composite bed are all to be made by Ag-ZnO (AgZnO).
Ag-ZnO (AgZnO) environment-protecting asepsis, have anti-melting welding, anti-electrical wear 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.With Agcdo (AgCdO) contact material, compare and have better resistance fusion welding, under the breaking current condition of 3000～5000A, have more preferably 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, fine copper and the moulding of Ag-ZnO Material cladding have been adopted, production cost is low, environment-protecting asepsis, have anti-melting welding, anti-electrical wear is good, arcing time is short, interrupting performance is high, Chinese People's Anti-Japanese Military and Political College's rush of current ability and the anti electric arc corrosion ability strong, be mainly used in rated current at 200A with interior Small And Medium Capacity low-voltage circuit breaker.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
