Patent ID: 8092252

Claim:
An electrical connector adapted for being mounted to a printed circuit board, comprising: an insulating body defining a receiving chamber with a front end being opened freely, a middle of a rear wall of the receiving chamber protruding forward into the receiving chamber to form a tongue, a top inside of the receiving chamber being further concaved upward to form a buckling cavity of which a top wall is provided with a window penetrating therethrough to communicate with the buckling cavity; a plurality of terminals disposed in the insulating body; an inner cover having a covering board which is positioned in the buckling cavity of the insulating body and faces to the window; and an outer shell mounted outside the insulating body, the outer shell having a base plate covered on the top wall and at least one soldering tail soldered to the printed circuit board, a portion of the base plate being punched downward to form a contact portion which stretches into the window to electrically contact the covering board of the inner cover so as to achieve a grounding function of the inner cover through the outer shell and the printed circuit board and further prevent the water which enters the receiving chamber from a front end mouth of the receiving chamber from flowing onto the printed circuit board.
