Electrical connector with improved grounding structure for shielding shell thereof

An electrical connector, comprising:

• a dielectric housing having a base, a mating projection extending forward from the base, and two towers formed at two lateral sides of the base;
• a plurality of terminals being received in the base and protruding into the mating projection;
• a shielding shell enclosing the mating projection of the housing;
• at least one board lock mounted in each of the towers of the housing for electrically connecting with a grounding trace of a printed circuit board on which the connector is mounted, the board lock forming a finger extending toward the mating projection and abutting against the shielding shell for establishing an electrical connection between the shielding shell and the board lock;
• at least one rivet extending through a corresponding tower and a platform of the board lock to fixedly connect the board lock and the tower together;
• and
• a terminal module, the terminal module comprising a board, the board being attached to a rear side of the housing, the terminals being inserted molded in the board, each terminal having a contact portion horizontally extending into a slot defined in the housing, and a tail portion horizontally extending from a bottom of the board.
