Abstract
An EMI gasket takes the form of a metal shroud that completely encircles a metal shielding cage. The shroud has an opening that is surrounded by a plurality of sides and each side has first and second flanges, which respectively contact the inner surface of the device faceplate and the exterior surfaces of the shielding cage. A pair of spring arms are provided in order to apply a biasing force against the shroud, thereby forcing it into contact with the faceplate. The spring arms each include a torsion loop, and each loop engages the shielding cage and fixes the rear position of the spring arms.
