Abstract
The utility model relates to a triple-composited contact adopting pure copper and a silver compound. The triple-composited contact comprises a pure copper matrix, a silver compound composite layer and an opposite-side composite layer, wherein the pure copper matrix is composed of a cylindrical head part and a cylindrical foot part, the cylindrical head part is thicker than the cylindrical foot part, the silver compound composite layer is composited at one end of the cylindrical head part of the pure copper matrix, the opposite-side composite layer is composited at one end of the cylindrical foot part of the pure copper matrix, and the compound in the composite layer is made of silver-nickel. The triple-composited contact disclosed by the utility model is molded by compositing the sliver-nickel and the pure copper, is low in production cost, has a favorable anti-fusion-welding performance and a favorable electrical-wear resistance, and can be well applied to the fields of medium/low alternating/direct-current relays, command switches, contactors, optical control switches, temperature controllers, timers of washing machines and the like.
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, has adopted fine copper and silver-colored nickel material composite molding, has good resistance fusion welding ability and anti-electric abrasioning performance.
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 to be processed by silver-colored nickel (AgNi).
Silver nickel (AgNi) has conductance height, characteristics that contact resistance is low and stable, have under the medium and small electric current good resistance fusion welding can and anti-electric abrasioning performance, material transfer is less under the dc condition.
Beneficial effect
The utility model relates to provides a kind of three composite contacts that adopt fine copper and silver compound; Fine copper and silver-colored nickel material composite molding have been adopted; The characteristics that silver-colored nickel conductance is high, contact resistance is low and stable have been utilized; Make the contact have good resistance fusion welding ability and anti-electric abrasioning performance, be mainly used in the timer of medium and small electric current AC and DC relay, command switch, contactor, light-operated switch, thermostat and washing machine etc.
