US 2002/0027009 A1 · Isolation apparatus for electronic equipment

Abstract

An electromagnetic isolation apparatus for an electronic device such as a portable telephone is provided which includes first and second shield cases and elastic members such as rubber cushions. The first and second shield cases are disposed within a casing of the electronic device to surround at least part of both surfaces of a printed circuit board mounted within the electronic device. The elastic members are interposed between an inner wall of the casing of the electronic device and an outer surface of the first shield case and between the inner wall of the casing and an outer surface of the second shield case to produce elastic pressures urging the first and second shield cases into conductive engagement with the printed circuit board.
