Abstract: An electrical connector receptacle includes a shield cover, a terminal unit and a fastener structure. The shield cover defines a cavity and an opening into the cavity and has a base panel with a base panel hole formed therethrough. The terminal unit has a first terminal unit mounting block having a first terminal unit mounting block hole, a second terminal unit mounting block having a second terminal unit mounting block hole, a first terminal assembly and a second terminal assembly. The first and second terminal unit mounting blocks are connected together in a stacked manner and are disposed in the cavity. With the first terminal unit mounting block hole, the second terminal unit mounting block hole and the base panel hole being in registration with one another, the fastener structure extends therethrough from the base panel and projects outwardly from the opening.
