Description
【発明の詳細な説明】 木発明は、電気接点材料に関するものである。[Detailed description of the invention] The invention relates to electrical contact materials.
１に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′ζζ銀酸酸化アンチモン用いられてきた。銀−
酸化アンチモンは、接触抵抗特性、耐溶着性の優れた接
点性能を有するが、アークによる消耗が大きく耐電圧、
耐絶縁性に劣るものである。Antimony 'ζζ silver acid oxide has been used as one of the electrical contact materials produced by the internal oxidation method since 1999. Silver-
Antimony oxide has excellent contact performance in terms of contact resistance and welding resistance, but it suffers from high arc wear and low withstand voltage.
It has poor insulation resistance.
そこで本発明者は、この電気接点材料よりもアークに対
する耐消耗性、耐電圧性、耐絶縁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 extensive research to develop an electrical contact material that has contact properties that are superior in arc wear resistance, voltage resistance, and insulation resistance than this electrical contact material, and as a result, has developed a satisfactory electrical contact material. This is what I discovered.
本発明の電気接点材料の一つは、ヒスマス０．１〜５重
量％と、すず１〜３重量％未満と、アンチモン１−１０
重量％と、残部銀から成る材料であって、且つ内部酸化
されているものである。One of the electrical contact materials of the present invention contains 0.1-5% by weight of hismuth, 1-3% by weight of tin, and 1-10% by weight of antimony.
% by weight, the balance being silver, and is internally oxidized.
本発明の電気接点材料の他の一つは、ビスマス０．１〜
５重量％と、すず１〜３重量％未満と、′ｒンチモン１
〜１０重量％と、鉄族元素０．０１〜１重量％と、残部
銀から成る材料であって、且つ内部酸化されているもの
である。Another electrical contact material of the present invention is bismuth 0.1~
5% by weight, 1 to less than 3% by weight of tin, and 1% tin.
-10% by weight, 0.01-1% by weight of iron group elements, and the balance 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
景％、ずず１〜３重置％未満と、アンチモン１〜１０重
量％とじた理由は、ビスマス０．１重駄％未満では酸化
アンチモンを均一微細に析出できず耐消耗性の改善効果
がなく、すずＨｆｌ量％未満では耐溶着性、耐消耗性に
関しては良好な結果が得られず、アンチモン１重量％未
満では十分な耐溶着性が得られず、またビスマス５重鍵
％を越えると、合金の融点が下がりすぎ跣１晶での内部
酸化が困難となり、ずず３重量％以上になると加工性が
劣化し、アンチモン１０重量％越えると合金の融点が下
がり１駈温での内部酸化が不可能、となり、また耐消耗
性が劣化するので、ヒスマス０．１〜５重蒙％、ずず１
〜３重量％未満、アンチ上２１〜１０重景％の範囲内で
は、耐溶着性、耐消耗性。In the electrical contact material of the present invention, the reason why bismuth is 0.1 to 5% by weight, less than 1 to 3% by weight, and antimony is 1 to 10% by weight is less than 0.1% by weight. With this method, antimony oxide cannot be precipitated uniformly and finely, and there is no effect of improving wear resistance.If the amount of tin Hfl is less than 1%, good results cannot be obtained in terms of adhesion resistance and wear resistance, and if the amount of antimony is less than 1% by weight, sufficient results are not obtained. Welding resistance cannot be obtained, and if the content exceeds 5% by weight of bismuth, the melting point of the alloy will drop too much and internal oxidation in the single crystal will become difficult, and if the content exceeds 3% by weight, the processability will deteriorate and antimony If it exceeds 10% by weight, the melting point of the alloy will drop and internal oxidation at 1 temperature will become impossible, and wear resistance will deteriorate.
- Less than 3% by weight, and within the range of 21 to 10% by weight, welding resistance and abrasion resistance.
ｌ１ｌｉノ電圧、耐絶縁性の充分満足できる電気接点材
料が得られるものである。It is possible to obtain an electrical contact material having a sufficiently satisfactory insulation resistance and voltage of 11li.
さらに本発明の電気接点材料の他の一つに於いて、ビス
マス０．１〜５重疑％、すず１〜３重量％未洒、アンチ
モン１〜１０重量％以外に鉄族元素０．０１〜０．５重
量％添加する理由は、これを電気接点材料に分散させた
場合、これにより得られる酸化Ｌ−スマス、酸化すず及
び酸化アンチモンの均一微細な分数によって、放電によ

満では酸化ビスマス、酸化ずず及び酸化アンチモンを均
一微細に分散させる効果が薄く、０．５重量％を超える
とそれ自体の偏析が増加するからである。Furthermore, in another one of the electrical contact materials of the present invention, in addition to 0.1 to 5% bismuth, 1 to 3% by weight of tin, and 1 to 10% by weight of antimony, iron group elements 0.01 to 5%. The reason for adding 0.5% by weight is that when it is dispersed in an electrical contact material, the resulting uniform fine fraction of L-smuth oxide, tin oxide, and antimony oxide further reduces consumption due to discharge. This is because if it is less than 0.01% by weight, the effect of uniformly and finely dispersing bismuth oxide, tin oxide, and antimony oxide is weak, and if it exceeds 0.5% by weight, segregation of the bismuth oxide itself increases.
次に本発明による電気接点材料の効果を明瞭ならしめる
