Abstract
Abstract A 360 degree shielded jumper connection using flat and flexible electrical cable is used. The cable has multiple signal conductors imbedded in an insulation layer, a broad flexible ground conductor overlaying a first section of the insulation layer, and a shield overlaying a second section of the insulation layer and the ground conductor. The ends of the signal conductors project beyond a cut end of the insulation for mating the signal conductors with a female type electrical connector. The insulation projects beyond a cut end of the shield. The ground conductor also projects beyond a cut end of the shield. A shield can encircles the cut end of the shield. And a ground strap pick up tab on the shield can contacts the projecting ground conductor to provide a 360 degree shielded jumper connection.
