An electrical connector (100) includes a metal shield (1) defining a receiving space (10), a number of contacts (2) received in the metal shield, an insulative body (3) molding over the metal shield and having a tongue portion (31) extending into the receiving space for retaining the contacts, and a reinforcing plate (4) attaching to the tongue portion for reinforcing the tongue portion. The insulative body has a number of slits (311) at the front side of the tongue portion and a number of slots (332) at a rear side of the tongue portion for respectively receiving a mold during molding. The reinforcing plate and the contacts are exposed to both the slits and the slots along opposite, vertical directions to make sure that the inserted molds bear against both the contacts and the reinforcing plate.
