Abstract
The utility model relates to a dual-composite contact made of pure copper and a silver compound, which comprises a silver compound composite layer and a pure copper substrate, wherein the pure copper substrate consists of a cylindrical head and a cylindrical leg thinner than the cylindrical head, and the silver compound composite layer is composited at one end of the cylindrical head of the pure copper substrate and made from silver-cadmium oxide. Since a head of the dual-composite contact is made of silver-cadmium oxide materials, the contact has an excellent fusion welding resistant performance and an excellent electrical wear resistant performance, is mainly applied to medium-capacity and high-capacity relays, contactors, alternating-current and direct-current switches and medium-capacity and high-capacity circuit breakers, and is particularly suitable for medium-capacity and high-capacity alternating-current contactors.
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, has adopted fine copper and Agcdo composite molding, makes the contact have high resistance fusion welding, anti-electrical wear property and lower contact resistance.
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 cylindric head and cylindric foot; The thickness of described cylindric head is greater than the thickness of cylindric foot, and the silver compound composite bed is compound in cylindric head one end of fine copper matrix.
The thickness of described head composite bed is 0.2mm～0.6mm.
Described composite bed compound is to be processed by Agcdo (AgCdO).
Described composite bed adopts advanced sintering, extrusion process that the cadmium oxide particle dispersion is distributed in to form Agcdo in the silver matrix; Under arcing; Cadmium oxide acutely decomposes, evaporate and make the contact surface cooling; Play the effect that reduces arc energy and blow-out, thereby make material have high resistance fusion welding, anti-electrical wear property and lower contact resistance.
Beneficial effect
The utility model relates to provides a kind of two composite contacts that adopt fine copper and silver compound; Fine copper and Agcdo composite molding have been adopted; Utilize the performance characteristics of Agcdo to make the contact have high resistance fusion welding, anti-electrical wear property and lower contact resistance; Be mainly used in big capacity relay, contactor, AC-DC switch and the middle low capacity circuit breaker big Capacity AC Contactor in being particularly suitable for.
