Description

Technical Field

[0001] The utility model relates to a connector terminal, an electrical connection component including the connector terminal, and a connector including the connector terminal or the electrical connection component. Background Art

[0002] In the prior art, large-sized connector terminals usually have a first elastic arm and a second elastic arm facing each other. In order to ensure the conductive performance, the base material of the connector terminal is usually copper. In order to improve the electrical contact performance, corrosion resistance and wear resistance, a metal plating layer as an electrical contact is usually formed on the copper base material of the first elastic arm and the second elastic arm respectively. The metal plating layer can be a nickel plating layer or a silver plating layer.

In order to ensure that the material of the electrical contact still has good electrical contact performance after aging, materials with good stress relaxation resistance are usually used, which leads to higher costs.
