Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric connectors, in particular to a high-voltage elastic smooth-contact nano copper connector. Background Art
[0002] High-voltage switches are suitable for rated voltages of 3kV and above, and are mainly used for breaking and closing electrical appliances of conductive circuits, requiring strong conductivity. The opening and closing of high-voltage switches is achieved by the contact between the contact and the contact piece. In order to improve the overall conductivity, the contact piece surface is usually silver-plated to reduce the contact resistance between the contact piece and the contact. However, since the width of the corresponding contact piece slot on the contact is only 1-1.5mm, the contact piece will be very thin. When the contact piece opens and closes, the contact piece will be distorted, and the silver-plated layer of the contact will be scraped off. At the same time, the large contact area and long-term opening and closing will also cause the silver-plated layer to wear, resulting in poor contact and affecting the conductive performance.
