ABSTRACT:
A data card is provided which has an electrically conductive rail (70, 72 FIG. 2 ) extending along its opposite sides and part of its rear, and connected to the ground plane (60) of a circuit board (46) of the card, to provide EMI (electromagnetic interference) shielding along the perimeter of the card. The rail has top and bottom edge portions (94, 96 FIG. 6 ) that are each bent into a U shape to extend around top and bottom ridges at the side of the card body to lock the rail in place. One edge portion includes a projecting tab (110) which is bent to extend inwardly and engage the ground plane (60) of the circuit board. The molded card body has a through hole (114) in its side portion, and the tab can extend into that hole before extending inwardly to the circuit board ground plane.
