Abstract

See full text

A personal computer CPU chassis (10) is sealed from the emission of radio frequency (RF) through the expansion slots (24) in the rear panel (18). An expansion slot seal (37) is dimensioned to fit over the edges or strips (32-34) of the slots (24) and is held in place by a slot cover (26). The seal (37) has a flat portion (46) for direct contact with the strips (32-34) and an angled portion (48) for direct contact with the cover (26). The cover (26) is held in place by a screw (54) and a retaining device (60) which forces the cover (26) into the seal (37). Thus a metal-to-metal seal is formed around the expansion slots (24) to inhibit the emission of RF therefrom.
