Abstract
An enclosure to be electromagnetically shielded includes first and second conductive joints, the first conductive joint comprising a channel including a pair of side walls and a back wall whereby to define a truncated wedge-shaped cross-section including an interior shoulder facing an enlarged chamber adjacent the back wall, a deformable body of polymer enclosed in a conductive mesh and abutting the back wall, and a nonplanar contact member engaging the mesh body, the back wall and each respective side wall at three points. The second conductive joint includes a flange plate to overlap the first joint and a blade to engage the contact members and the mesh body whereby to provide radiation shielding. A metallic gasket recessed in the flange is compressed between the conductive joints to resist passage of radiation, dust or moisture.
