1. An electrical connector, comprising:
- an insulative housing;
a plurality of terminals retained in the insulative housing, the terminals having a plurality of soldering portions extending out of a rear surface of the insulative housing;
a shielding shell attached to the insulative housing, the shielding shell having a tail portion located at a rear end thereof; and
an insulator insert-molded with a rear end of the shielding shell, the insulator at least wrapping partly an external surface of the tail portion to seal up a rear end of the insulative housing and extend the soldering portions of the terminals through the insulator so as to expose rear ends of the soldering portions of the terminals to an exterior;
whereinthe tail portion has a plurality of grooves filled by the insulator; and
the shielding shell has a top wall and a bottom wall located oppositely, and a pair of side walls connected with the top wall and the bottom wall, and the tail portion has a thickness smaller than thicknesses of the top wall, the bottom wall and the side walls.

Abstract
An electrical connector includes an insulative housing, a number of terminals retained in the insulative housing, a shielding shell attached to the insulative housing, and an insulator insert-molded with a rear end of the shielding shell. The terminals have a number of soldering portions extending out of a rear surface of the insulative housing. The shielding shell has a tail portion located at a rear end thereof. The insulator at least wraps partly an external surface of the tail portion to seal up a rear end of the insulative housing and extend the soldering portions of the terminals through the insulator to expose a rear surface thereof.

5. An electrical connector comprising:
-
a terminal module including two rows of terminals with a metallic shielding plate therebetween in a vertical direction and commonly insert-molded within an insulative housing, the housing forming a front tongue portion with opposite surfaces on which front contacting sections of the terminals are exposed, and a rear surface through which rear soldering portions of the terminals extend rearwardly in a front-to-back direction; a die-casting metallic tubular shielding shell receiving said terminal module therein to form a sub-assembly with a receiving space behind the rear surface of the housing; and an insulator received within the receiving space to integrally securing both said terminal module and the shielding shell;
whereinthe shielding shell includes a tail portion having at least one groove communicating with the receiving space in a direction perpendicular to the front-to-back direction; the insulator is insert-molded with the tail portion of the shielding shell to at least wrap partly an external surface of the tail portion of the shielding shell. - View Dependent Claims (6, 7, 8, 9, 10, 11)

12. A method of making an electrical connector, comprising the steps of:
-
providing a plurality of terminals and a metallic shielding plate; insert-molding an insulative housing with the terminals and the metallic shielding plate to form a terminal module, the terminals having a plurality of soldering portions extending rearwardly out of a rear surface of the insulative housing along a front-to-back direction; providing a metallic die-casting tubular shielding shell having different thicknesses on different portions thereof, to enclose the terminal module to commonly form a sub-assembly; and applying an insulator to said sub-assembly to cover said rear surface of the insulative housing with rear ends of the soldering portions extending rearwardly and exposed to an exterior by over-molding the terminal module and the shielding shell together;
whereinthe insulator protectively covers a tail portion of the shielding shell at least in a vertical direction perpendicular to the front-to-back direction. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
