Patent attributes
An electrical receptacle connector includes an insulated housing, receptacle terminals, and a metallic shell. The insulated housing includes a base portion and a tongue portion outwardly extending from the base portion. Two metal sheets are arranged at two sides of the tongue portion. Each of the metal sheets includes a hook structure protruding from a side portion of the tongue portion and a through hole adjacent to the hook structure. The receptacle terminals are held in the base portion and disposed at the surface of the tongue portion. The metallic shell includes a receptacle cavity. The insulated housing is held in the receiving cavity. The contact arms are formed by the through holes of the metal sheets in an elastic manner, to avoid the hooks on both sides of the electrical plug connector in contact with the metal sheets in a poor interference manner.
