Problems solved by technology
Most of the existing contact elements are made of pure silver and pure copper directly by manual riveting and automatic riveting, with low strength, low hardness, low resistance to fusion welding and arc burning resistance, and the materials involve a variety of precious metals Materials. Most of the existing composite contact manufacturing equipment has complex structures and poor molding efficiency. Not only is the raw material wasted, but the strength and hardness of the composite contacts after molding are low, the connection is unstable, the cost is high, and the scope of application is small.

The invention provides a three-composite contact and a manufacturing device thereof. The three-composite contact comprises a copper-based layer and a silver alloy layer, wherein a cylindrical foot is arranged at the top of the copper-based layer; the silver alloy layer comprises a top silver alloy layer and a bottom silver alloy layer; the top silver alloy layer is in a ring structure; an inner ring of the top silver alloy layer is connected with the cylindrical foot in a sleeving manner; the bottom silver alloy layer is fixed at the bottom of the copper-based layer; the top silver alloy layer is made of an AgMgNi material; and the bottom silver alloy layer is made of an AgSnO2 material.
Description
technical field [0001] The invention relates to the field of manufacturing electrical contact elements, in particular to a triple composite contact and a manufacturing device for the triple composite contact. Background technique [0002] The contact elements commonly used in the market are small in size, but have very strict performance requirements. Most of the existing contact elements are made of pure silver and pure copper directly by manual riveting and automatic riveting, with low strength, low hardness, low resistance to fusion welding and arc burning resistance, and the materials involve a variety of precious metals Materials. Most of the existing composite contact manufacturing equipment has complex structures and poor molding efficiency. Not only is the raw material wasted, but the strength and hardness of the composite contacts after molding are low, the connection is unstable, the cost is high, and the scope of application is small.
