Abstract
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.
