Abstract
The utility model discloses a rivet composite contact, which comprises a matrix and a composite layer. The composite layer is positioned at the top of the matrix. The rivet composite contact has the advantages of good electrical contact performance, high production efficiency, low production cost, good assembly accuracy and high reliability.
Description
Technical field
The utility model relates to a kind of rivet composite contact, belongs to the electric device 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.
Existing in the market rivet contact all is by precious metal usually; Like simple a kind of metal matrixes 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 the product that causes producing can't be sold on market and use on a large scale.
Summary of the invention
For overcoming the defective of prior art, the utility model discloses a kind of 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, and good reliability is easy to apply.
For realizing the foregoing invention purpose, the utility model is realized through following technical scheme:
A kind of rivet composite contact is made up of matrix and composite bed, and said composite bed is positioned at the top of said matrix.
The composite contact of the utility model, matrix, composite bed can adopt suitable material to process according to the needs of practical application, and preferred, said matrix is that metallic copper or copper alloy are processed, thereby guarantees conductivity and plasticity preferably.Said composite bed is that metal platinum or platinum alloy are processed, and has excellent electrical contact performance.
Wherein, the shape of composite bed, matrix does not receive special restriction, and preferred, said composite bed bottom surface is an arc convex, fits in said matrix top and composite bed bottom surface.
It will be understood by those skilled in the art that above-mentioned described outer convex is meant the circular arc type shape of composite bed bottom surface for giving prominence to the matrix direction.This kind structure has effectively increased the contact area of matrix and composite bed, forms better electrical contact performance.
Wherein, said matrix is the T type.
Through above-mentioned improvement, the rivet composite contact of the utility model, not only electrical contact performance is good, and production efficiency is high, and production cost is low, has effectively improved the assembly precision and the reliability of element, thus production application on a large scale.
The utility model the contact product adopt the powder metallurgic method preparation; Its composition, quality are easy to control than other process, have guaranteed the contact uniformity in product performance, and can be further through advanced flouring technologies such as the chemical coating method of utilization, coprecipitation, atomization, mechanical alloyings; Make other constituent particle refinements; And in evenly distribute copper or the copper alloy matrix,, improve the contact properties of product and be of great benefit to improving the metallographic structure of contact material; Can significantly improve the density of product, thereby improve the electrical property of contact material.Thereby be applied to various circuit breakers, line protection switch, failure current protection switch, earth leakage circuit-breaker, sliding brush etc.
In market, the acid bronze alloy environmental protection contact of the utility model has replaced contact products such as present general Agcdo, siller tin oxide, has solved the high problem of silver contact cost in the circuit breaker; Its cost is low, serviceability stable, is that products such as present circuit breaker, A.C. contactor, air switch use the first-selected contact product in the contact.The product of the utility model has passed through each item tests such as 25kv breaking capacity, and it is qualified to detect.
Description of drawings
Fig. 1 is the utility model structure chart.
Embodiment
With reference to figure 1, be the rivet composite contact of the utility model, comprise the matrix 2 of T type, be provided with composite bed 1 on matrix 2 tops, wherein the bottom surface that contacts with matrix 2 of composite bed 1 is an arc.
Wherein, matrix 2 is processed for metallic copper or copper alloy, and composite bed 1 is processed for metal platinum or platinum alloy.
Wherein, matrix and composite bed combination are the welding fusion
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.
