Electrical receptacle connector
An electrical receptacle connector includes an insulated housing, a plurality of terminals, and a metallic plate. The terminals and the metallic plate are at the insulated housing. The terminals are held at the insulated housing and arranged into two rows. The metallic plate is at a tongue portion of the insulated housing and between the terminals which are arranged into two rows. The metallic plate has a main body and a plurality of extension portions. Each of the extension portions extends outwardly from the main body and corresponds to a protrusion of a corresponding one of the terminals. A distance between each of the protrusions and a corresponding one of the extension portions is less than a distance between each of the contact portions and the corresponding one of the extension portions. A retaining spacing is between the protrusions of the terminals and the extension portions of the metallic plate.
