Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector terminal. Background Technology

[0002] A board-to-board connector typically consists of a plug connector and a socket connector, both of which contain conductive terminals. The conductive terminals of the plug connector and the socket connector abut against each other to make the board-to-board connector conductive. In the prior art, connector terminals are mostly formed by repeatedly bending copper strips. This not only results in low production efficiency of elastic terminals but also causes internal stress at the bending points, leading to a reduction in the elasticity of that part. Furthermore, the male and female terminals often have single-point contact. After prolonged use, this part loses its elasticity, causing the elastic terminal to lose its original elasticity and fail to make contact with the other terminal, resulting in poor contact. Therefore, this utility model proposes a connector terminal. Utility Model Content
