Abstract

A connector for connecting to a charging seat includes a housing, a cover, a conductive element or metal bar, and a connecting piece. The housing is formed with a terminal hole that allows one end of a charging terminal of the charging seat to be inserted. The cover is installed on an end of the housing and formed with a conductive element opening. One end of the conductive element is inserted into the housing through the opening of the cover. The connecting piece is provided in the housing and adapted to connect the one end of the conductive element to the one end of the charging terminal.

First claim
