Abstract
The utility model relates to a double-composite contact made of pure copper and sliver alloy. The contact comprises a sliver alloy composite layer (1) and a pure copper substrate (2), wherein the pure copper substrate (2) comprises a cylindrical head part and a cylindrical foot part thinner than the former. The double-composite contact provided by the utility model has the advantages of low production cost, large material strength, high welding resistance and electric arc damage resistance, large electrical conductivity and low contact resistance, is suitable for low-voltage devices lower than 10 A current and can be applied to various fields to replace contacts made of pure sliver.
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 alloy.
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 alloy, has adopted fine copper and thin brilliant silver-colored composite molding, and production cost is low, and the strength of materials is big, and resistance fusion welding and anti-electrical arc erosion performance are high.
The utility model solves the technical scheme that its technical problem adopted: a kind of two composite contacts that adopt fine copper and silver alloy are provided; Comprise silver compound layer 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 silver compound layer is compound in cylindric head one end of fine copper matrix.
The thickness of described silver compound layer is 0.2mm～0.6mm.
Described silver compound layer is made up of thin brilliant silver (FAg).
Thin brilliant silver (FAg) be the silver alloy that in silver, adds a small amount of alloying element formation, and the crystal grain of silver matrix that contained refinement has improved intensity, resistance fusion welding and the anti-electrical arc erosion performance of material.
Beneficial effect
The utility model relates to provides a kind of two composite contacts that adopt fine copper and silver alloy, has adopted fine copper and thin brilliant ag material composite molding, and production cost is low; The strength of materials is big; Resistance fusion welding and anti-electrical arc erosion performance are high, and conductance is high, and contact resistance is low; Be applicable to the low-voltage electrical apparatus below the operating current 10A, the contact application that can replace the fine silver material is to multiple occasion.
