Abstract: An electrical receptacle connector is provided for contacting conductive surfaces of a conductive substrate. The connector includes an insulated housing out of a terminal retaining member and an outer shell enclosing the insulated housing. The outer shell includes two side plates extending toward two sides of a mount member at the rear portion of the insulated housing.
