Many problems with terminal blocks
As the contact structure design is unreasonable, the material selection error, mold instability, processing size tolerance, surface roughness, heat treatment plating and other surface treatment process is unreasonable,
he effect of the insulator is to keep the contacts in the correct position and to insulate the contact between the contacts and the contacts, the contacts and the housing
improper assembly, storage environment and improper operation, will be in contact with the Contact parts and mating parts caused by poor contact.
So the contact must have excellent structure, stable and reliable contact retention and good electrical conductivity
