Introduction to main materials of electrical connector

In our daily life, we have seen a lot of wire accidents, one part is caused by the overload of the wire, the other part is caused by the loose wire connector.

Wire connector within the box is not in conformity with the specification, the wire is not affected by load cases, no matter, as long as the one on the switch will trip, and wire terminal box will be a few sound under the skin, “snapped” appeared again after the trip, all is due to this phenomenon, wire connector is not standard, the voltage at the load cases, due to poor contact.Therefore, although the wire connector is small, it plays an extremely important role in circuit engineering.

So we need to know the main material of electrical connector, plug wire connector material introduction.
Contact material: thickened electrolytic copper + tin plating (excellent electrical conductivity, thermal conductivity, ductility, corrosion resistance, prevent contact heating).
Contact point coating: tin (corrosion resistance, oxidation resistance, good air tightness).
Insulation material (housing) : nylon 66(resistance to leakage current breakdown, elasticity, rigidity, corrosion resistance, environmental protection free of halogen and formaldehyde.Temperature – 35 ℃ — 105 ℃).
Pressure reed material: steel (cold stamping (stamping die installed on the pressure machine for material processing) processing, high precision, no burr, repeated use can maintain elasticity, strong tensile and corrosion resistance, increase the resistance to wear of wire insertion.
