Abstract

Electromagnetic interference (EM11 radiated from electronic equipment is normally undesirable, and means are usually taken to contain the EM1 within the cabinet or covers surrounding the equipment. Such means include filters applied to the input and output lines to the equipment as well as enclosing the equipment in covers and sealing any openings in the covers as well as cracks or seams formed where sections of the covers interface or mate.

Electromagnetic interference (EM11 radiated from electronic equipment is normally undesirable, and means are usually taken to contain the EM1 within the cabinet or covers surrounding the equipment. Such means include filters applied to the input and output lines to the equipment as well as enclosing the equipment in covers and sealing any openings in the covers as well as cracks or seams formed where sections of the covers interface or mate.

An improved EM1 seal mechanism is disclosed which eliminates the problem of the seal being scrubbed by the covers during installation of the covers.

With reference to Figures 1 and 2, an improved EM1 seal mechanism 10 is disclosed which includes a mesh covered rubber seal 12 attached by suitable means to leaf- type spring 14. Figure 1 shows the top cover 16 being pushed down with respect to the bottom cover 18 and forcing spring 14 away from bottom cover 18. As spring 14 is deflected away from bottom cover 16, rubber seal 12 is displaced away from the path of the top cover 16 so the top cover 16 does not contact or scrub the rubber seal 12 during moving of the top cover 16 into proper position.
