  • Adapter card electromagnetic compatibility shielding
    Patent number: 7659482
    Abstract: An electromagnetic shield comprising an electrically conductive frame for establishing electrical contact between a chassis wall and an expansion card mounting bracket. The frame has a plurality of spring fingers interconnected about a perimeter of a central opening in the frame, wherein each spring finger defines a central axis that extends outwardly away from the central opening. The frame may include a substantially planar portion adjacent the central opening in the frame, wherein the plurality of spring fingers incline along the central axis to extend out of the plane defined by the substantially planar portion. The incline of the spring fingers allows a mounting bracket to slide laterally without jamming against the side of a spring finger during installation, removal or side-to-side shifting of the mounting plate.
