Description
Technical field
The utility model relates to field, electronic devices and components contact, particularly novel three composite contacts of one.
Background technology
Contact is element conventional 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 and 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 resistance to electrical arc erosion performance low, and consumption is large, expensive, production cost is high, can only be applied in the fields such as radio, communication microswitch and small area analysis electrical equipment.
Utility model content
For existing technical deficiency, the utility model provides a kind of novel three composite contacts.
To achieve these goals, technical solution adopted in the utility model is: a kind of novel three composite contacts, comprise matrix and composite bed, described matrix is made up of head and foot, described head and foot are cylindric, and described head diameter is greater than foot's diameter, and described composite bed comprises head composite bed and foot's composite bed, described head composite bed is compound in head upper surface, described foot's composite bed compound and foot's lower surface.
Described matrix is that pure copper material is made, and described composite bed is that silver alloy is made, and described silver alloy is thin brilliant silver composition.
The beneficial effects of the utility model: the utility model relates to provides a kind of three composite contacts adopting fine copper and silver alloy, have employed fine copper and thin brilliant ag material composite molding, production cost is low, the strength of materials is large, resistance fusion welding and resistance to electrical arc erosion performance high, conductance is high, and contact resistance is low, be applicable to the low-voltage electrical apparatus of below operating current 10A, the contact application of fine silver material can be replaced to multiple occasion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of novel three composite contacts, comprise matrix 1 and composite bed, described matrix 1 is made up of head and foot, described head and foot are cylindric, and described head diameter is greater than foot's diameter, and described composite bed comprises head composite bed 2 and foot's composite bed 3, described head composite bed 2 is compound in head upper surface, described foot's composite bed 3 compound and foot's lower surface; Described head composite bed 2 and the thickness of foot's composite bed 3 are 0.2mm ~ 0.6mm.
Described matrix 1 is made for pure copper material, and described composite bed is that silver alloy is made, and described silver alloy is thin brilliant silver composition; The main processing technology of the utility model is compound cold-heading, will the silk material of thin brilliant silver (FAg) and fine copper bi-material under cold headers impulsive force, two kinds of metals form radial plastic deformations formation upsetting shapes.
