Cold-press terminal should choose good plasticity and high conductivity copper materials made of fine stamping process, and then the surface according to the matte tin plating or copper (not easy oxidation). Cold insulation terminals, terminal points naked terminal, insulation terminal general environmental protection PVC flame retardant plastic, welding and naked terminal needs to be silver. Identify the cold-press terminal is good or bad.

1, whether the copper (copper content of 99.95% or more, a lot of use is 97%, and even copper alloy);

2, the material thickness is up to standard;

3, whether tin plating, the surface is matte silver, a lot of zinc plating is seriously affect the conductive

4, whether to use environmental protection PVC flame retardant plastics;

5, whether with silver welding, the more is to use the brazing of easy cracking 6 surface whether there is pitting and scratches.
