Abstract:

An EMI shielding spacer gasket assembly for interposition under a predetermined compressive load within an electronics enclosure between a first surface and an oppositely-disposed second surface of the enclosure. The assembly includes a frame member and an electrically conductive, elastomeric member extending along at least a portion of the perimeter of the frame member as retained on a corresponding peripheral edge surface thereof. The elastomeric member has an outboard side which is compressible axially under the compressive load for providing an electrically conductive pathway between the surfaces of the enclosure. In an uncompressed orientation, the outboard side of the elastomeric member exhibits elongate upper and lower bearing portions which are disposed at a spaced-apart radial distance from the frame member to define a corresponding bending moment arm. Each of the bearing portions is angularly deflectable relative to the moment arm to effect the compression of the elastomeric member under a relatively low compressive load.
