Abstract: A flat cable shielding device comprises a metal foil sleeve formed of an upper and a lower length of conductive metal foil. To aid the insertion of flat cable into the shielding device, a low-friction inside surface is provided on the inside surface of the metal foil sleeve. The outside of metal foil sleeve is covered with an electrically insulating film, to provide wear and scuff protection. Both the low-friction inside surface and other outer coating are coupled to the metal foil sleeve preferably using adhesive. Good electrical connections can be made easily to the shielding device which can be used as a floating ground or can be grounded to a common system ground as desired.
