Description

Technical Field

[0001] This utility model relates to a terminal and a connector including the terminal. Background Technology

[0002] In existing technologies, to achieve electrical connection between terminals and mating terminals, a flexible cantilever is typically formed on the terminal, through which electrical contact is made with the mating terminal. However, the electrical contact of ordinary flexible cantilever is unreliable, especially in vibrating environments, where unstable electrical contact is prone to occur.

[0003] Furthermore, in existing technologies, the entire terminal is made of copper or copper alloy. This results in a high surface roughness of the terminal, increasing the friction between the terminal and the mating terminal, thus leading to excessive insertion and extraction forces. In addition, using copper or copper alloy for the entire terminal also results in higher costs. Utility Model Content
