An electrical receptacle connector includes a metallic shell, an insulated housing in the metallic shell, a plurality of terminals at the insulated housing, and a metallic plate. The terminals are arranged in two rows, and the metallic plate is at the insulated housing and between the terminals in the two rows. The metallic plate includes a first through hole, several second through holes, and several communication holes. By allowing that the communication holes to be in communication with the first through hole and the second through holes in the metallic plate, the molding efficiency for forming the tongue portion with the filling of the plastic materials can be increased.
