An electrical connector includes a main body, a plurality of terminals fastened to the main body, an outer shielding shell surrounding the main body together with the terminals, and a cover covered outside the outer shielding shell. The main body is mounted to a circuit board. Rear ends of the terminals are mounted to the circuit board. Front ends of the terminals are exposed out of the main body. A rear end of the cover defines a resilient plate. A rear edge of the resilient plate is bent perpendicular to the resilient plate to form a rear plate. The resilient plate is separably mounted to an outside of the outer shielding shell to make the rear plate disposed behind or above the main body and the outer shielding shell.
