All the parts that can't rotate according to the requirements of hot-dip galvanizing are generally made of stainless steel. The fasteners below M are made of stainless steel, and the rest are hot-dip galvanizing.
Conductive part of the copper tube soft connection type, the middle contact is "handshake" type self type contact, spring external pressure type no current through, isolation switch only one contact point in the middle, the rest are fixed connection with soft connection.
The new contact structure is adopted, one end of the contact plate is fixed with the contact seat, and the sliding contact at the end of the contact finger is changed to fixed contact by the deformation of the contact plate and the contact pressure produced by the spring, so as to improve the conductivity reliability;
Contact spring to external type, in order to avoid spring shunt;
Add magnetic locking plate to improve dynamic and thermal stability
