Wear-resistant and oxidization-resistant IC clamping seat terminal

Abstract

The invention discloses a wear-resistant and oxidization-resistant IC clamping seat terminal. The wear-resistant and oxidization-resistant IC clamping seat terminal comprises base plates, a spring sheet and contact terminals, wherein the spring sheet is arranged between the base plates, a plurality of contact terminals are arranged on the spring sheet, a contact region is arranged at a free end ofeach contact terminal and is designed in an arc shape, and a gold plating layer is further coated on a surface of a top end of the contact region. In the wear-resistant and oxidization-resistant IC clamping seat terminal, planes of two sides of the contact region are changed to be in arc shapes, the cross section of the terminal is ensured, and meanwhile, the contact region of the whole terminalis smooth without burrs; and the wear-resistant and oxidization-resistant IC clamping seat terminal is processed and formed by employing an imported full-automatic stamping machine, high accuracy is achieved, the cost is reduced, a client is convenient to use, contacts are arranged in order, the wear-resistant and oxidization-resistant IC clamping seat terminal is good in elasticity, multi-contactelastic force is uniform, gold is electroplated at contact positions by a full-automatic line, the wear-resistant and oxidization-resistant IC clamping seat terminal is resistant to wear and oxidization, and the plug service lifetime of a product is substantially prolonged by favorable design of the terminal contact region.

Description

technical field [0001] The invention relates to the technical field of middle and high-grade components of new electronic components in electronic information technology, in particular to a friction-resistant and anti-oxidation IC card holder terminal. Background technique [0002] In view of the flatness requirements of the card holder terminal and the structural design of the card holder contact area, the contact surface of the ordinary card holder terminal is designed to be flat, but the flat terminal is very easy to produce burrs during the stamping process. Gold-plated terminals are easily scratched after repeated plugging and unplugging, resulting in poor contact conduction and reducing the plug-in life of the socket. At the same time, there are dimensional tolerances such as springback during bending and deformation during heat treatment. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a friction-resista...
