A receptacle connector assembly for an electronic memory card provides and maintains a well-grounded connection between cover plates of the memory card via resilient contacts of a ground contact of the receptacle connector assembly. A memory card includes two conductive cover plates sandwiching the receptacle connector assembly. The receptacle connector assembly comprises an insulative housing formed with two rows of terminal receiving cavities for receiving signal and ground terminals. A distal terminal receiving cavity includes first and second partitions defining first and second ground terminal receiving cavities for receiving first and second ground terminals, and an insertion slot for receiving a ground element. The first and second partitions are formed with a cutout. A ground element positioned in the insertion slot includes a body, two wings extending from opposite ends of the body, and resilient contacts extending from the body inwardly of the wings. The wings make contact with the cover plates and the resilient contacts contact the first and second ground terminals via the cutouts to common the cover plates and ensure that the cover plates are at a common electrical potential despite any fluctuations in manufacturing or assembly tolerances.
