Electric connector

The utility model discloses an electric connector. The electric connector comprises a connecting seat, a build-in circuit board and a switching module. The build-in circuit board is arranged at the rear portion of the connecting seat, and the build-in circuit board is provided with a gap. The switching module is arranged at the rear of the circuit board, the switching module comprises an insulating seat and a plurality of conductive terminals, the insulating seat is made from plastic and rubber, and the plurality of conductive terminals are fixed in the insulating seat; the front end of the insulating seat is provided with an abutting surface which clings to the rear surface of the build-in circuit board; and an abdicating groove is recessed from the front end of the insulating seat to the back, the abdicating groove has a wall surface arranged at the rear of an abutting surface, and a positing pin protruding forwards from the wall surface matches the gap and is fixed. By disposing the abdicating groove in the electric connector, deckle edges or chips scraped off of the positioning pin and the wall surface of the gap of the build-in circuit board can be accumulated in the abdicating groove, the switching module can be prevented from floating, the abutting surface of the insulating seat can be flatly clung to a rear surface of the build-in circuit board, and the conductive terminals can be accurately welded to a main circuit board.
