Corrugated strip gasket for an electronic enclosure joint to reduce both electromagnetic and radio frequency radiation

An arrangement to provide an electronic enclosure joint that reduces both electromagnetic and radio frequency radiation between walls of an enclosure of an electronics product has a corrugated metal strip serving as a gasket. The walls of the enclosure have inner conductive surfaces which contact the apices of the corrugated strip. The walls form a channel for the corrugated strip, with the inner conductive surfaces being kept a pre-determined distance apart. The force exerted by the corrugated strip provides electrical continuity between the inner conductive surfaces, while plastic deformation of the strip is avoided by maintenance of the pre-determined distance between the inner conductive surfaces. Because of the relatively low force needed to ensure electrical continuity, creep-prone materials such as plastic can be used for the walls, without the need for an excessive amount of fasteners to hold the walls together against the force exerted by the corrugated strip.
