Abstract

An enclosure is shielded from electomagnetic radiation, especially for testing electronic equipment such as cellular telephones. An electrically conductive housing (8) with a rectangular chamber has an open top with a flange (12) extending upward from its perimeter. An electrically conductive closure (4) hinged to the housing has a peripheral groove or slot (3) holding a conductive spring finger assembly (2). When closed, the flange fits into the spring finger assembly, forcing the fingers (11) apart and against the walls of the groove. This provides excellent conductive connection between the housing and the closure through the flange, the fingers, and the groove. The conductive spring finger assembly is machined from thin beryllium copper strip, formed to final shape into straight portions and corner portions with small radii and then heat treated to retain its final spring form.
