Abstract:
An EMI shielding spacer gasket assembly for interposing under a predetermined compressive load within an electronics enclosure between a first surface and an oppositely-disposed second surface of the enclosure, said assembly comprising:a frame member having an inner and an outer perimeter and a cross-sectional profile of a closed geometric area which extends along an axially-directed first central axis disposable generally perpendicular to the surfaces of the enclosure and along a radially-directed second central axis disposable generally parallel to the surfaces of the enclosure, and which is bounded by an upper and a lower face surface each disposable in opposition with a corresponding one of the first or second surfaces of the electronic enclosure, and by an inner and outer peripheral edge surface which define, respectively, the inner and outer perimeter of said frame member; andan electrically conductive, elastomeric member extending along at least a portion of one or both the inner or outer perimeter of said flame member, said elastomeric member having an inboard side which is retained on a corresponding peripheral edge surface of said frame member and an outboard side which is axially compressible under said compressive load intermediate the surfaces of the enclosure for providing an electrically conductive pathway therebetween, said outboard side of said elastomeric member exhibiting in an uncompressed orientation elongate upper and lower bearing portions each extending in cross-section along a common longitudinal axis from an internal proximal end to an external distal end terminating beyond a corresponding one of said face surfaces of the frame member for contact with a corresponding one of the surfaces of the enclosure, said longitudinal axis being disposed a spaced-apart radial distance from the first central axis of said frame member,whereby said distal end of each of said bearing portions is angularly deflectable responsive to said compressive load.
