11. An electrical connector comprising:
-
an insulative housing having a base portion and a tongue portion extending forwardly from the base portion; a plurality of terminals retained in the insulative housing; a shielding shell attached to the insulative housing to form a receiving space, the tongue portion exposed out of the receiving space; and an insulative shell enclosing the shielding shell to form a receiving cavity to receive the tongue portion extending forwardly beyond the shielding shell, the insulative shell defining a stepping portion on thereof an interior surface facing the receiving cavity to form a front inner surface located in front of the stepping portion and a rear inner surface located behind the stepping portion, wherein the shielding shield is located behind the stepping portion and an exterior surface of the shielding shell intimately contacts the rear inner surfaces of the insulative shell; and the insulative shell is insert molded with the shielding shell. - View Dependent Claims (12, 13, 14)
