Abstract

An electrically conductive rectangular housing contains a conductive elastomeric tube with a resilient core material. The housing also contains an inflatable seal which is preferably a flattened inflatable elastomeric member. Inflation of the elastomeric member causes the minor axis of the seal to become elongate, compressing the tube into conductive contact with sections of the enclosure and forcing a part of the tube from a slot in the housing and into contact with the surface of a conductive section of the enclosure disposed opposite the slot. Upon deflation, the seal returns to its uninflated shape due to its 'memory' characteristic, thus permitting the conductive tube to withdraw from contact with the conductive section opposite the slot and assume its unextruded shape.
