Problems solved by technology

When splicing wires of different diameters, in the conventional splicing method, there is a tendency that the outer peripheral portion of the splice portion is less and less spliced, resulting in a lot of waste.
In addition, it is difficult to form a flat joint interface because the silver alloy, which has a small diameter at the initial stage of forging, is caught in the deformation of the copper alloy.

Abstract

The invention claims a manufacturing method can be a small quantity of silver alloy the interface bonding strength so as to improve the eliminating manufacturing the waste of time and obtaining the long period of time and exert stable contact performance and durability the excellent composite contact. A method for producing a compound contact method of the composite contact on the small diameter of the base part of one end of the part to form big diameter of the flange part and having a contact part and foot contact part of the flange part of the upper surface part and is composed of silver alloy consisting of the foot part the contact part of the back surface of the jointed under the state of the flange part of the of the lower part of the big diameter part and the small diameter of the base part are integrally formed and it is composed of the copper alloy consisting of said method has: Once forming working procedure and secondary forming working procedure.

Description

technical field [0001] The present invention relates to a method for manufacturing a composite contact with excellent durability that exhibits stable contact performance over a long period of time with a small amount of silver alloy. [0002] This application claims priority based on Japanese Patent Application No. 2011-141053 for which it applied on Jun. 24, 2011, and uses the content here. Background technique [0003] Instead of the single contact made of silver alloy, in order to achieve silver saving, only the contact part is made of silver alloy material, and the composite contacts replaced by copper-based materials are widely used as relays, switches, electromagnetic switches, Electrical contacts used in circuit breakers, etc. This composite contact has a large-diameter flange formed at one end of a small-diameter base in the shape of a rivet as a whole, and has a contact portion made of a silver alloy constituting the upper portion of the flange, and a joint contact...
