Movable shielded cable egress

摘要

A device having an upper plate comprising a top face and a bottom face with an opening. A lower plate comprising a top face and a bottom face substantially parallel to the upper plate, with an opening. A middle plate between and substantially parallel to the upper plate and lower plate, capable of moving with respect to the upper plate and lower plate, and having a top face a bottom face and at least one opening. A plurality of gaskets configured to electrically connect the upper plate, the middle, plate, and the lower plate and provide an interface that is designed to allow the middle plate to slide substantially parallel to the upper plate and the lower plate. At least one waveguide through the at least one opening of the middle plate.

主权项

1. A device for attenuating electromagnetic emissions, the device comprising:
an upper plate having a first top face, a first bottom face and a first opening spanning from the first top face to the first bottom face; a lower plate substantially parallel to the upper plate and having a second top face a second bottom face, and a second opening spanning from the second top face to the second bottom face; a middle plate between and substantially parallel to the upper plate and lower plate, capable of moving with respect to the upper plate and lower plate, and having a third top face a third bottom face and at least one third opening spanning from the third top face to the third bottom face; a first gasket physically connected to the first bottom face of the upper plate, bordering the first opening, and electrically connecting the upper plate and the middle plate; a second gasket physically connected to the second top face of the lower plate, bordering the second opening, and electrically connecting the lower plate and the middle plate; a third gasket physically connected to the third top face of the middle plate, bordering at least one edge of the third top face of the middle plate, and electrically connecting the upper plate and the middle plate; a fourth gasket physically connected to the third bottom face of the middle plate, bordering at least one edge of the third bottom face of the middle plate, and electrically connecting the lower plate and the middle plate; and at least one waveguide that extends through the at least one third opening spanning at least from the first top face of the upper plate to the second bottom face of the lower plate.
