Background technique

TYPE C female connectors are widely used in various electronic equipment. A socket is provided on the terminal of the electronic equipment, and the electronic equipment is inserted into the TYPE C female connector through the TYPE C plug to realize charging or signal transmission of the electronic equipment.
