Abstract
The utility model relates to a three-composite contact made of pure copper and silver compound. The three-composite contact comprises a pure copper base (2), a silver compound composite layer (1) and opposite side composite layers (3), and is characterized in that the pure copper base (2) comprises a frustum-shaped head and cylindrical legs, the frustum-shaped head is thicker than the cylindrical legs, the silver compound composite layer (1) is composited at one end of the frustum-shaped head of the pure copper base (2) and forms a cone together with the frustum-shaped head of the pure copper base (2), and each opposite side composite layer (3) is composited at one end of the corresponding pure copper base (2). The three-composite contact is made of the pure copper, silver tin oxide and indium oxide by means of composite molding, oxide particles are thin, materials are high in strength and hardness, and the three-composite contact is fine in material transfer resistance and suitable for being applied to AC-DC relays.
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 the composite molding of silver-tin oxide or indium oxide material, the strength of materials, hardness height, and anti-material transfer is functional.
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 frustum head and cylindric foot; The thickness of described frustum head is greater than the thickness of cylindric foot; The silver compound composite bed be compound in the fine copper matrix the frustum head an end and form cone with the frustum head of fine copper matrix, 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 silver-tin oxide or indium oxide (AgSnO2In2O3).
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 silver-tin oxide or indium oxide material, oxide particle is thinner, and the strength of materials, hardness are higher; Anti-material transfer is functional, relatively is fit to be applied on the AC-DC relay.
