Effect of copper alloy characteristics on terminal appearance and size

Qualified appearance and size are the basic conditions for ensuring the performance of connector terminals. Most of the terminals are mainly deformed by bending during the stamping process. In the bending process, the terminal mainly has the problem of dimensional tolerance caused by the material’s bending and rebound, and the appearance problem of bending and cracking.

The effect of copper alloy bending characteristics on terminal bending cracking Bending cracking is a fatal quality problem for connector terminals.

Enterprises and customers cause different levels of losses. During the stamping and bending process, the copper alloy is subjected to a bending moment. The curved concave surface of the neutral shaft is subjected to compression deformation, and the curved convex surface of the neutral shaft is subjected to tensile deformation. When the convex surface is subjected to tensile deformation beyond the deformation limit that the material can withstand, cracking occurs.
