Abstract

The present invention features a new 'filter line' cable of very thin construction. The thinner cable has a reinforcing mesh layer that lends physical strength to the otherwise thinner, weakened cable. Additionally, the reinforcing mesh provides grounding and some shielding. The reinforcing mesh layer is made of a thin metal wire or metal-coated fibers. The filter line cable has a conductive core having a primary insulation layer. Over the primary insulation is a filtering layer made up of metal-coated ferromagnetic particles of ferrite or magnetite dispersed within a polymeric matrix such as Viton, a fluorinated elastomeric polymer. The ferromagnetic particles may be 'spherical', to enhance the filtering effect. The filtering layer provides the 'filter line' protection against internal RFI and microwave interferences traveling down the wire. Over the filtering layer is a layer of metal wire or metal-coated fibers, woven or served into a mesh. This layer shields the filtering layer and provides protection against external EMI signals. The reinforcing mesh layer is lightweight and provides a minimum of shielding coverage, i.e., approximately between 15 to 50% of the filter line layer; its primary purpose is to provide physical reinforcement and grounding.
