Abstract:
An apparatus for electromagnetic shielding a printed circuit board extender interconnecting first and second system enclosures from emitting electromagnetic radiation, comprising:a first bracket attached to the first system enclosure surrounding a first opening in the first system enclosure through which the printed circuit board extender extends into the first system enclosure; a second bracket attached to the second system enclosure surrounding a second opening in the second system enclosure through which the printed circuit board extender extends into the second system enclosure; and a sleeve attached to both the first and second brackets enclosing the printed circuit board extender without contacting the printed circuit board extender and the sleeve having folding and interconnected sections such that a length of the sleeve is adjustable to fit a distance between the first and second system enclosures and rigid in all other axes where the first and second brackets and the sleeve electrically interconnect the first and second system enclosures and the sleeve comprises a ferromagnetic and electrical conductive inner and outer surfaces and a center material that is a high resistivity and magnetically lossy ferrite material to prevent eddy currents on the inner surface from causing magnetic fields within the center material.
