Description

【発明の詳細な説明】本発明は、電気接点材料に関するものである。[Detailed description of the invention] The present invention relates to electrical contact materials.

従来より内部酸化法により製作した電気接点材料の一つ
として銀−酸化マンガンが用いられてきた。　銀−酸化
マンガンは、電気伝導度が低いため接点開閉時に温度上
昇が著しく耐溶着性に劣るものである。Silver-manganese oxide has conventionally been used as one of the electrical contact materials manufactured by internal oxidation. Since silver-manganese oxide has low electrical conductivity, the temperature rises significantly when the contacts are opened and closed, and the welding resistance is poor.

そこで本発明者は、この電気接点材料よりも耐（１）溶着性に優れた接点特性を有する電気接点材料を開発す
べく鋭意考究の結果、満足できる電気接点材料を見い出
したものである。Therefore, the inventor of the present invention has conducted intensive research to develop an electrical contact material having contact properties that are superior in (1) welding resistance than this electrical contact material, and as a result, has found a satisfactory electrical contact material.

ているものである。One of the electrical contact materials of the present invention is a material consisting of 0.1 to 5% by weight of bismuth, 1 to 10% by weight of zinc, 1 to 10% by weight of manganese, and the balance being silver, and is internally oxidized. It is something that

である。Another electrical contact material of the present invention is bismuth 0.1~
5% by weight, 1-10% by weight of zinc, and 1-10% by weight of manganese.
It is a material consisting of 1n% by weight, 0.01 to 0.5% by weight of iron group elements, and the balance silver, and is internally oxidized.

本発明の電気接点材料に於いて、ビスマス０．１〜５重

じた理由は、ビスマス０．１重量％未満では耐溶着性を
改善する効果が少なく、曲鉛１重量％未満では耐消耗性
に関しては良好な結果が得られず、マンガン１重量％未
満では耐消耗性。The reason why the electrical contact material of the present invention contains 0.1 to 5% by weight of bismuth, 1 to 10% by weight of zinc, and 1 to 10% by weight of manganese is that less than 0.1% by weight of bismuth improves the welding resistance. If the amount of bent lead is less than 1% by weight, good results cannot be obtained in terms of abrasion resistance, and if the amount of manganese is less than 1% by weight, the abrasion resistance is poor.

ｉ足できる電気接点材料が得られるものである。If sufficient welding resistance is not obtained, and bismuth exceeds 5% by weight, the melting point of the alloy will drop too much and the
If it exceeds '11'f Thi, '%, oxides will precipitate in a layered form and the contact resistance will become unstable. Il! Lead 1~
．． Within the range of 10 M1ia% and 1 to 10 wt% manganese (sufficient adhesion resistance, abrasion resistance, and contact resistance characteristics)
It is possible to obtain an electrical contact material that can be used in many ways.

化ビスマス。Furthermore, in another one of the electrical contact materials of the present invention, bismuth (0.1 to 5% by weight, zinc 1 to 10% by weight, manganese 1 to 10% by weight) and iron group elements 0. OI ~ 0 trillion wt%
The reason for adding this is that when it is dispersed in an electrical contact material, the resulting uniform and fine dispersion of hismuth oxide, zinc oxide, and manganese oxide further reduces consumption due to discharge. Bismuth oxide below the market weight%.

酸化亜鉛及び酸化マンガンが均一微細に分散せず、０．
５ｊｌ量％を超えるとそれ自体の偏析が増加するからで
ある。Zinc oxide and manganese oxide are not uniformly and finely dispersed, and 0.
This is because if the amount exceeds 5jl, the segregation of itself increases.
