Problems solved by technology

The disadvantage of this kind of copper-aluminum terminal is that because other alloys are used for welding between the copper and aluminum, the overall resistance of the terminal increases more, resulting in a large loss of current passing, reducing the transmission efficiency and improving the overall resistance of the terminal. Power transmission loss

Abstract

The invention discloses a copper-aluminum socket connector for the electric conduction, the preparation method thereof and the application thereof. The socket connector comprises an aluminum body and a copper plug integrated into a whole by welding. The preparation method comprises the following steps: (1) manufacturing the molded aluminum body and the copper plug, and cleaning the welding surfaces of both the aluminum body and the copper plug; and (2) welding the aluminum body and the copper plug into an integrated part by adopting a flash welder or a spin friction welder to obtain the copper-aluminum socket connector semi-product for the electric conduction. The socket connector is mainly applied to a moving contact, a static contact or a conductive contact arm in a high and low voltage switch cabinet or a vacuum circuit breaker. The socket connector has the advantages of non-contact resistance, no galvanic corrosion, smaller resistance, less current conveyance loss, improved current transmission efficiency and reduced power transmission and transformation loss.

Description

technical field [0001] The invention belongs to the technical field of medium and high voltage conductive material design, and in particular relates to a conductive copper-aluminum connector and its manufacturing method and application. Background technique [0002] With the price increase of raw materials, the price of copper for electrical purposes is also getting higher and higher. In order to reduce costs and improve competitiveness, many companies use aluminum to make parts instead of copper parts. If it is used for general conductive parts , It is basically feasible to use aluminum products instead of copper products. However, for connectors, if aluminum products are used, there are defects of insufficient strength and wear resistance. In addition, because most of the external conductive products are Copper products, so aluminum products often have the disadvantage of galvanic corrosion when they are used. [0003] In order to make up for this deficiency and to reduce...
