Abstract
An apparatus for securing an electromagnetic shield in a conductive, casing includes a conductive frame, spring devices on a first edge of the frame that secure an electromagnetic shield in the frame and electrically couple the shield to the frame, and spring devices on a second edge of the frame that secure the frame in an aperture through a conductive casing and electrically couple the frame to the casing. An electromagnetic shielding apparatus includes a conductive frame, an electromagnetic shield of conductive material formed into cells, and spring devices on the frame that hold the shield in the frame and electrically couple the shield to the frame.
