Connecting piece on plug connector

Abstract

The utility model discloses a connecting piece on a plug connector, which comprises a plurality of conductive pieces, each conductive piece comprises a connecting part, a plugging part and a fixing part, the connecting part is used for being electrically connected with a cable core wire, the outer side surface of the fixing part is attached to a plastic shell, and the plugging part is used for being plugged with a charging socket. A through fixing hole is formed in the fixing part, a separator is formed on the inner wall of the fixing hole along the axial direction of the fixing hole in a punching manner, and the separator formed by punching can keep the adjacent conducting strips separated and avoid side surface attachment when the conducting strips are electroplated, so that electroplating liquid can effectively electroplate all surfaces of the conducting strips; when molten plastic particles are poured into the mold cavity to perform injection molding on the shell and the conducting strips, the fixing holes are filled with the particles, and the conducting strips are further fixedly connected with the fixing part after cooling, so that the risk of assembly looseness of the conducting strips and the shell is reduced, and the overall quality and the service life of the electric tool plug connector are improved.
