Abstract
The utility model discloses a silver alloy irregular rivet composite contact. The contact is a dual-layer structure and is formed by a contact working surface and a welding surface, wherein the welding surface is located on the upper portion of the contact working surface. The contact not only has good electrical contact performance but also has high production efficiency and low production cost. By the aid of the contact, the welding performance of the contact is improved obviously during usage.
Description
Technical field
The utility model relates to a kind of rivet composite contact, belongs to the electric component field.
Background technology
The electrical contact element is a kind of low-pressure electronic equipment product and household electronic products such as switch, relay, thermostat, circuit breaker, contactor, controller, timer of being widely used in; The electrical contact element mainly contains three kinds: 1, riveted spare, with closing-up on copper spare; 2, weldment is welded on the sheet contact on the copper spare; 3, stamping parts becomes element with the composite band punching out.
Special-shaped rivet contact in the market directly is made up of the contact working face; The main material of matrix is a precious metal; Like simple a kind of metal working faces such as gold or silver, use and produce actual, this contact basis material is selected for use more single; Because its electrical contact performance receives the restriction of single metal material, its electrical contact performance is poor; And because metal purity is had certain requirement, production efficiency is low aborning, and production cost is higher, and in use welding performance is poor, and is all relatively poor like welding temperature, the many indexs such as molten flow point, wettability and weld strength of pure metallic silver.
Summary of the invention
For overcoming the defective of prior art, the utility model discloses a kind of silver alloy abnormity rivet composite contact, through the architecture advances to traditional contact, not only electrical contact performance is good to make it, and production cost is low, good reliability, and its good welding performance.
For realizing the foregoing invention purpose, the utility model is realized through following technical scheme:
A kind of silver alloy abnormity rivet composite contact is the double-decker of contact working face and solder side composition, and said solder side is positioned at said contact working face top.
For the contact performance and the welding performance that guarantee, the surface of said solder side has small salient point; Preferably, said small salient point is uniformly distributed in the upper surface of solder side.
The silver alloy abnormity rivet composite contact of the utility model; Said contact working face is that silver alloy is processed; Guaranteeing that it has the good electrical contact performance, the silver alloy that described silver alloy includes but not limited to be the basis with the Ag-Cu-Zn alloy, silver tungsten, silver-nickel, silver-colored ashbury metal etc.
The silver alloy abnormity rivet composite contact of the utility model, said solder side is that copper alloy is processed.
Wherein said copper alloy is used to improve the welding performance of contact.Those skilled in the art have the type that knowledge can be learnt the copper alloy of good welding performance commonly used according to this area, include but not limited to tungsten-copper alloy, ormolu, nisiloy copper alloy, chromium copper master alloy etc., preferably tungsten-copper alloy.
Through above-mentioned improvement, the silver alloy of the utility model abnormity rivet composite contact, not only electrical contact performance is good, and production efficiency is high, and production cost is low, and has effectively improved its welding performance, thus production application on a large scale.
The contact working face of the utility model improves the density of product through adopting silver alloy, thereby improves the electrical property of contact material, can be applied to various circuit breakers, line protection switch, failure current protection switch, earth leakage circuit-breaker, sliding brush etc.Solder side adopts copper alloy can adopt the powder metallurgic method preparation; Its composition and quality are easy to control than other process, can guarantee the contact uniformity in product performance, through using advanced flouring technologies such as chemical coating method, coprecipitation, atomization, mechanical alloying; Make other constituent particle refinements; And in the silver alloy working face matrix that evenly distributes,, improve the contact properties of product and be of great benefit to improving the metallographic structure of contact material; Silver alloy can adopt the production of sintering extruding process simultaneously; Can make its density up to 99.9%, the physical and mechanical properties of material is greatly improved, make product have better anti-melting welding, anti-electric arc simultaneously and burn scaling loss and low and electrical properties such as stable contact resistance.
Description of drawings
Fig. 1 is the utility model structure chart.
Embodiment
With reference to figure 1, the silver alloy abnormity rivet composite contact for the utility model comprises contact working face 2, above contact working face 2, is provided with solder side 1.
Wherein, contact working face 2 is processed for silver alloy, and solder side 1 is processed for copper alloy.
Wherein, working face and solder side combination are the welding fusion, and through the test of each items such as 25kv breaking capacity, the utility model contact is qualified.
Above execution mode and accompanying drawing it will be appreciated by those skilled in the art that a kind of more excellent realization into the utility model; The improvement that those skilled in the art are carried out on this basis; The for example variation of shape, ratio, size, material etc. still belongs to the protection range of the utility model.
