Abstract
The utility model discloses a silver-nickel/copper-nickel composite electrical contact. The silver-nickel/copper-nickel composite electrical contact comprises a silver-nickel alloy layer and a copper-nickel alloy layer which are compounded into a whole by cold heading, wherein the copper-nickel alloy layer is of a spot-welded layer of the electrical contact, and a plurality of bubble points are convexly arranged on the outer surface of the copper-nickel alloy layer. The silver-nickel/copper-nickel composite electrical contact disclosed by the utility model has the advantages of low cost and good stability in electrical connection.
Description
Technical field
The utility model relates to a kind of electrical contact, specifically refers to a kind of silver-colored nickel/copper nickel compound electrical contact.
Background technology
At present, small-power contactor and the used electric contact of middle high power relay all adopt the noble metals such as silver, cause manufacturer's infusion of financial resources large because silver is expensive, make the cost of electric contact high, also cause downstream complete-system vendor cost to rise, make economic benefit and social benefit affected by this very large.Therefore, develop the lower-cost current material of a kind of employing, and the reliable and stable electrical contact of electric connection structure, will have extraordinary economic benefit.
Summary of the invention
The purpose of this utility model is the shortcoming and defect that exists in order to overcome prior art, and the silver-colored nickel that a kind of cost is lower and electrical connection intensity is high/copper nickel compound electrical contact is provided.
For achieving the above object, the technical solution of the utility model is silver-nickel layer and the albata layer that includes the cold-heading composite integrated, and described albata layer is the some layer of electrical contact, and the outer surface of this albata layer has projection to be provided with a plurality of bubble points.
The outer surface that further setting is described albata layer has projection to be provided with 5 bubble points.
The utility model adopts existing silver-nickel and corronil as material, be combined into electric contact, compared to the traditional electrical contact of using fine silver fully, the precious metal use amount is few, and cost greatly reduces, and by being provided with bubble point, moment can produce a large amount of heat during the electric contact welding, and can be connected together with tactile bridge welding faster, the electric contact after the welding and the bond strength of tactile bridge are high, do not have the problem of coming off.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model embodiment layer structure front view;
Fig. 2 the utility model embodiment bubble point distribution map.
Embodiment
Below by embodiment the utility model is carried out concrete description; only be used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection range, the technician in this field can make some nonessential improvement and adjustment to the utility model according to the content of above-mentioned utility model.
Embodiment structural representation of the present utility model shown in Fig. 1-2, include silver-nickel layer 2 and the albata layer 1 of mutual composite integrated, the point layer that described albata layer 1 is electrical contact, and the outer surface of this albata layer 1 has projection to be provided with a plurality of bubble points 11, this bubble point 11 of the present embodiment has 5, and it distributes as shown in Figure 2.
Electric contact of the present utility model is processed composite molding contact shape by cold headers with silver-nickel and corronil cold-heading.The contact of composite molding is put into vacuum electric furnace with protective gas with 580 ℃ temperature destressing diffusion annealing 6 hours, vacuum cooled is to room temperature more again, and last clean is finished and obtained silver-colored nickel/copper nickel composite electric contact.
The electric contact of the utility model processing is with the method processing composite electric contact of cold headers cold-heading molding, has that production cost is low, processing is simple to operation, easily forms large-scale production.Can save silver more than 60%.Economic benefit and social potential are huge.
