電気接点材３を下面もしくは上面にして配置し、これを
加熱してロウ付けを行っている。Conventionally, brazing at the time of manufacturing electrical contacts is the fifth.
As shown in the drawing, a brazing material 5 is arranged between a joining surface 2 of a base metal 1 and a joining surface 4 of an electric contact material 3 and is placed in a jig made of stainless steel, carbon, or the like. The electric contact material 3 is disposed in the mounting hole with the lower surface or the upper surface, and this is heated to perform brazing.

業は手間を要し、生産効率を低下させるばかりではな
く、ロウ付けした電気接点材３に疵を生じる場合もあ
り、製品歩留まりの低下という問題も生じる。However, at the time of brazing, the molten brazing material 5 flows out from the joint surface to the peripheral surfaces (side peripheral surfaces and surfaces) of the base metal 1 and the electric contact material 3 as shown in FIG. The protruding portion 8 of the brazing material 5 on the peripheral surface of the electric contact material 3 has a bad influence on the function as an electric contact, the incorporation into a device, a caulking operation and the like. Therefore, after brazing, it is necessary to perform an operation of removing the protruding portion 8. This removal operation is troublesome and not only lowers the production efficiency, but also may cause flaws in the brazed electrical contact material 3 and causes a problem of lowering the product yield.
この対策として、ロウ材の厚みや面積を小さくする等
してロウ材の量を少なくすることも考えられるが、台金

低下を招くことになり、製品の品質の維持上、これらの
調整は難しい。As a countermeasure, it is conceivable to reduce the amount of the brazing material by reducing the thickness or the area of the brazing material. These adjustments are difficult to maintain the quality of the product.
本発明において解決すべき課題は、従来の電気接点材
のロウ付け作業を何等変更することなく、ロウ材の電気
接点材の周面へのはみ出しを防止し、しかも確実なロウ
付けを得るための手段を見出すことにある。The problem to be solved in the present invention is to prevent the brazing material from protruding to the peripheral surface of the electric contact material without changing the conventional brazing operation of the electric contact material, and to obtain a reliable brazing. Finding the means.
本発明は、ロウ付けすべき台金と電気接点材の両方の
接合面の周縁に円弧状の面取り部からなるロウ材の逃げ
空間を形成してロウ付けすることを特徴とする電気接点
材のロウ付け方法である。The present invention provides an electric contact material characterized in that a brazing material escape space composed of an arc-shaped chamfer is formed at the peripheral edge of both joining surfaces of the base metal and the electric contact material to be brazed and brazed. This is a brazing method.
板状のロウ材を電気接点材と台金との間に挟み込む状
態で昇温した場合、接合面からはみ出ようとする溶融ロ
ウ材は逃げ空間に入り、電気接点材の機能部分にはみ出
すことはなく、また、ロウ材による接合能を何等阻害す
ることもない。When the temperature is raised while the plate-shaped brazing material is sandwiched between the electrical contact material and the base metal, the molten brazing material that is about to protrude from the joint surface enters the escape space and does not protrude into the functional part of the electrical contact material. Also, there is no hindrance to the joining ability by the brazing material.
