Abstract
An electromagnetic shielding spring gasket assembly includes a coil spring for blocking the propagation of electromagnetic waves therepast. The coil spring includes a plurality of coils having a major and a minor axis and canted along a center line defined by an intersection of the major and minor axes and may be interconnected in a manner forming a radial garter-type canted-coil spring. A back angle of each coil defines the disposition of a trailing portion of each coil with respect to a line normal to the center line which determines a radial load-deflection characteristic of the canted-coil spring assembly. A front angle of each coil defines the disposition of a leading portion of each coil with respect to the normal line. The plurality of coils are noninvasively supported in an orientation for controlling the blocking of electromagnetic waves, for radial loading of the radial garter-type canted-coil spring and for controlling the resilient characteristics of the radial garter-type canted-coil spring.
