本発明は、内部酸化法によつて製造される銀一酸化物系
の複合電気接点材料に係る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a silver monoxide-based composite electrical contact material produced by an internal oxidation method.
従来から耐溶着性・耐消耗性等に優れた銀−酸化物系の
複合電気接点材料としては、銀−酸化カドミウム系の接
点材料が広く用いられてきた。Conventionally, silver-cadmium oxide-based contact materials have been widely used as silver-oxide-based composite electrical contact materials that have excellent welding resistance, wear resistance, and the like.
しかしながらカドミウムは、人体に有害な物質であり、

ゲルマニウム系の接点材料を見い出したものである。However, cadmium is a substance harmful to the human body.
Since it tends to evaporate during dissolution, it requires equipment and its use is not desirable. On the other hand, among silver-based contact materials, there is already a contact material made of silver-nickel, which does not use cadmium, or which is relatively similar to silver-cadmium oxide contact material. is inferior to silver-cadmium oxide contact materials in terms of welding resistance in the medium current range, and its range of use and conditions of use are quite limited. For these reasons, there is a strong demand for a contact material that does not use cadmium and has good welding resistance. As a result of intensive research to develop a contact material that can meet the above requirements, the inventors of the present invention discovered a silver-copper oxide-germanium oxide contact material as a contact material with excellent welding resistance. It is something that

The most significant effect obtained by co-adding 7i is that the copper oxide particles become finer and the welding resistance of the contact material is improved. Electrical contacts made from a contact material made by internally oxidizing a silver alloy consisting of only silver and copper are
The rate of welding is high and the wear is large, making it unsuitable as a composite electrical contact for medium to heavy loads. That is, the effect can only be exhibited by co-adding copper and germanium to silver. Next, the reason why the components of the composite electrical contact material of the present invention are limited as described above is that by adding copper to silver, the internal oxidation rate and the original electrical conductivity of silver-copper oxide are further improved. This is to improve the welding resistance and abrasion resistance of silver-copper oxide by taking advantage of the fact that it is not extremely harmed by elements and adding germanium.

く、電気伝導率が低くなるからである。Also, the reason why the composition range was limited as above: If copper is less than 0.5 to 1, it will not be possible to prevent the internal oxidation rate and electrical conductivity from decreasing due to other additive elements, and if it is more than 15, the internal oxidation will be prolonged. This is because it takes time, has poor workability after internal oxidation, and has low electrical conductivity.

銅合金台座にろう付してなる複合電気接点である。This is because if the germanium content is less than 0.1 to 1, the effect of improving the welding resistance will be small, and if the germanium content is more than 7 to 1, the workability will deteriorate. Also, the element co-added with copper is germanium 1.
The reason for using seeds is to make the copper oxide particles finer without lowering the electrical conductivity, and the addition of two or more metals such as manganese and antimony in addition to germanium is more noticeable than when using only one metal. This is undesirable because it has no effect and only adds to the effort and cost of material management and collection work during scrapping. Of course, if metal elements other than the above-mentioned components are added to the composite electrical contact material of the present invention, it is also possible for the same reason to disturb the shape of the structure, which has excellent welding resistance, so it is best to avoid adding metal elements as much as possible. desirable.
Next, in order to further clarify the effects of the composite electrical contact material of the present invention, specific examples of manufacturing electrical contacts and their test results will be described in detail. Items 1 to 2 in the table below are actual products made of the electrical contact material of the present invention, which are melted and cast, then rolled into plates with a thickness of 1.5mm, and then rolled into 6mm thick plates.
