Abstract:
In an assembly for shielding an electronic system from electromagnetic interference and electrostatic discharge, the electronic system having a shelf unit with parallel spaced guide slots for holding a plurality of circuit cards side by side in a parallel array, the assembly comprising:a plurality of faceplate assemblies each secured to an edge of a respective one of said plurality of circuit cards, wherein each of said faceplate assemblies is accessible from outside said shelf unit for installing and removing the respective circuit card from the shelf unit, and wherein each of said faceplate assemblies includes an elongated conductive bracket member extending at least the length of the circuit card edge with two side walls of the bracket member extending parallel to the respective circuit card; anda plurality of resilient compressible conductive gaskets each secured to one side wall of a respective bracket member, each gasket extending the length of its respective bracket member, wherein each gasket in its uncompressed state extends away from its respective bracket member in a direction orthogonal to the respective circuit card by a distance greater than the spacing between facing bracket member side walls of adjacent circuit card faceplate assemblies;wherein each bracket member has its respective gasket secured to the same corresponding side wall as all the other bracket members so that between each adjacent pair of bracket members there is a single respective gasket filling the gap between facing bracket member side walls;THE IMPROVEMENT COMPRISING:a plurality of guide fins mounted to the front of the shelf unit, each of the guide fins being parallel to the guide slots, the guide fins being located and spaced so that each guide fin is between a respective pair of adjacent faceplate assembly bracket member side walls.
