The pressing mechanism of the high-current terminal is a mechanism that generates pressure between the wire and the conductive strip. Only by generating enough pressure can a lower contact resistance be ensured and a good connection can be formed. Therefore, the reliability of the pressing mechanism directly affects the The wire connection is good or bad.

1. Identification of plastic parts
For photovoltaic energy terminals, there are mainly two parts. There are several aspects to the identification of plastic parts. The first is the identification of raw materials, which can be identified mainly by smell and testing. Good materials do not have any odor after processing. The test is mainly to see the flame retardant properties and wire drawing of the plastic. The longer the wire drawing, the better the quality.
2. Identification of conductor parts
There is no special method for this, because in the process of processing, in order to slow down the oxidation rate of copper parts, the surface layer is coated with metal, so as long as the coated metal is removed with a file, the material of the photovoltaic energy terminal can be known.
