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.

A resilient EMI shielding and/or environmental sealing gasket for interposition between a first interface surface and an oppositely-disposed second interface surface. The gasket is formed of an elongate body of indefinite length which extends along a longitudinal axis. The body includes base and apex surfaces, and opposing first and second lateral surfaces which extend intermediate the base and apex surfaces. The base surface itself extends along the length the body as configured for proximally supporting the gasket on the first interface surface. The apex surface, in turn, extends radially from the longitudinal axis for distal contact with the second interface surface, and further extends along the longitudinal axis as defining a first waveform profile characterized as having a first periodic series of alternating first high and low amplitude intervals. The second lateral surface also extends along the longitudinal axis as defining a second waveform profile which is disposed generally transverse to the first waveform profile and which is similarly characterized as having a second periodic series of alternating second high and low amplitude intervals. The gasket so formed is deformable under a predetermined compressive force between the first and second interface surfaces into a stressed orientation characterized in that the body is deflected intermediate the base and apex surfaces.
