Abstract
An electrical receptacle connector includes a dielectric housing having a body portion receiving a number of contacts therein and two ears each defining a central hole with a hexagonal upper section and a round lower section and two elongate slits. A shielding/grounding shell is formed with a body portion covering the body portion of the housing, and two wings each formed with four mounting tongues fittingly positioned on four mounting seats defined in the hexagonal upper section of the hole of the corresponding ear and two grounding feet extending through the corresponding slits. Two conductive posts are each formed with a domed upper section located above the body portion of the shielding/grounding shell, a middle hexagonal section positioned on the corresponding tongues of the shielding/grounding shell, and a lower cylindrical section received in the corresponding round lower section of the corresponding hole and defining a threaded portion therein. When screws are inserted through a printed circuit board to threadedly engage with the threaded portions to fix the connector on the printed circuit board, the hexagonal sections of the posts tightly urge the tongues against the mounting seats to fix the shielding/grounding shell to the housing of the connector.
