Abstract

An electric connector comprises a first conduction end, a metal shell as a second conduction end and with an empty cavity inside and at least one insulator. The first conduction end sticks out of the front-end of the metal shell through the insulator. The electric connector is characterized in that the first conduction end comprises a front end and a back end part which are separable, and correspondingly, the back end of the metal shell also comprises a front end and a back end part which are separable. Moreover, the anterior and posterior inner walls of the metal shell around the front end and back end part are provided with magnetic elements which can attract mutually. Compared with prior art, by pulling the magnet through electric wires, the connector is loosened and divided into two parts to make conduction state converted to power off state in no time, solving the hidden danger of the pulled down consumer equipments by electric wires.
