強度のばらつきが大きくなり易く、均一な品質を
確保することが困難であつた。 By the way, in the case of a solid rivet type electrical contact 1 as shown in Fig. 1a, the above method can be automated, so by supplying a noble metal wire and a strip-shaped terminal plate, an electrical contact as shown in Fig. 1b can be made. 5 can be easily produced with one mold, but in the case of a rivet type composite electrical contact 4 as shown in FIG. 2, the process of joining the contact material and the base material is Because of this, the equipment required to automatically create electrical contacts is complicated, and the current situation is that it has not been put to practical use. For this reason, when making an electrical contact equipped with the rivet-type composite electrical contact 4, the contact must be crimped separately, which is time-consuming and makes it impossible to reduce costs. In addition, in the case of a rivet-type composite electrical contact, when the contact material and the base material are joined, each contact is joined separately, which tends to lead to large variations in joint strength, making it difficult to ensure uniform quality.

It is an object of the present invention to provide a method for manufacturing a rivet-type composite electrical contact that uses a small amount of material, allows automation through continuous processing in the production of electrical contacts, and can reduce costs.

できる。 As described in detail above, in the method for manufacturing a riveted composite electrical contact of the present invention, a layer of strip-shaped composite contact material is formed by providing a layer of strip-shaped composite contact material in the longitudinal direction at the center of the upper surface of a strip-shaped base material. There is no need to bond contact materials to individual base materials as in the case of the method of manufacturing electrical contacts. Therefore, variations in the bonding strength between the base material and the contact material are extremely small and stable. In addition, a hollow cylindrical body is made by multiple drawing processes of a band-shaped composite contact material in which a layer of band-shaped contact material is provided on a band-shaped base material, and then a hollow rivet type is formed by compressing the upper part of the hollow cylindrical body several times. Since composite electrical contacts are made, the quality is more uniform compared to the conventional manufacturing method of riveted composite electrical contacts, and both the contact material and base material are extremely thin, so less material is used, and particularly expensive precious metal contact materials are not required. Since the amount can be reduced to the minimum, there is no wastage of materials and it can contribute to resource conservation. Furthermore, in the method for manufacturing a riveted composite electrical contact of the present invention, a strip-shaped composite contact material is obtained by simultaneously carrying out feeding of a strip-shaped base material and feeding of a strip-shaped contact material or construction of contact plating. Since a hollow rivet-type composite electrical contact can be obtained by molding the hollow cylindrical body and the rivet head using a compression molding machine, it is possible to obtain a hollow rivet-type composite electrical contact by combining the feeding of the terminal plate with this series of steps. By adding the process of attaching the contacts, it is possible to automate the continuous processing of the electrical contacts and reduce costs.

In addition, since the chattering phenomenon can be absorbed and alleviated by the elastic action, the performance when opening and closing the contacts is further improved. Furthermore, since there is a contact material on the underside of the rivet head and on the outer peripheral surface of the rivet leg, the base material will not oxidize and the contact between the terminal material and the base material will be stable after the terminal material is inserted into the contact mounting hole of the terminal material and caulked. Therefore, there is no possibility of conduction failure or loosening of the rivet type composite electrical contact.
