つている。 Conventionally, in order to manufacture multi-pole electrical contacts used in relays, switches, etc., a strip-shaped base material 1 made of nickel silver shown in FIG. 1a is cut in the longitudinal direction, and then this narrow strip-shaped base material 1' is pressed into a comb-teeth shape as shown in Figure b, and a U-shaped base material 2 made of phosphor bronze is attached to the tip of the comb teeth 1a of the pressed band-shaped base material 1'' as shown in Figure c. The base material 2 is fixed in sequence, that is, a through hole is bored at the tip of the comb tooth 1a, and a through hole is also bored at the tip of both sides of one base material 2, and the base material 2 is fixed in the through hole of the comb tooth 1a. The eyelet pins 3 formed from the comb teeth 1a are inserted into the pins by matching the through holes of the comb teeth 1a, and fixed by caulking, and then a resin mold 4 is molded on the fixed part of the base material 2 as shown in Fig. d. Then, the contact materials 5 are sequentially welded to the base ends of both sides of the base material 2, and then the base ends of both sides of the base material 2 and the base end of the strip-shaped base material 1'' are welded as shown in FIG. A bipolar electric contact 6 is made by cutting every two comb teeth.

致命的な欠陥が生じる。 However, in the electric contact 6 manufactured by such a manufacturing method, the left and right base materials 2' may vary in the vertical direction as shown in FIG. 2a, expand in the left-right direction as shown in FIG. Therefore, if such an electrical contact 6 is used in a relay, switch, etc., variations in spring pressure will occur, resulting in fatal defects as an electrical contact such as poor contact or no contact on one side. .

の左右のベース材２′に集中することが判明した。 Therefore, the present inventor discovered that the left and right base materials 2' of the electric contact 6 may vary in the vertical direction as described above.
When the band-shaped base material 1 was cut in the longitudinal direction, distortion occurred on both sides of the narrow band-shaped base material 1', and after that, When the band-shaped base material 1' is punched with a comb-tooth press, the strain on one side is eliminated, but the strain on the other side remains. As shown, a spiral twisting force is generated. As a result, when the base material 2 is fixed to this strip-shaped base material 1'' and a resin mold 4 is molded for each of the plurality of fixed parts, the twist of the strip-shaped base material 1'' is fixed by the resin mold 4, and the electric contact 6
It was found that the particles were concentrated on the left and right base materials 2'.

を提供するものである。 The present invention has been made focusing on this point,
Even if the narrow strip base material obtained by cutting the strip base material in the longitudinal direction is pressed into a comb-like shape, twisting stress will not be generated, and the left and right base materials will not have vertical variations or horizontal expansion. An object of the present invention is to provide a method for manufacturing an electric contact that can obtain a multi-pole electric contact without confinement.
