  • Patent number: 9105376
    Abstract: A shielded electrical ribbon cable is disclosed. The cable includes a plurality of conductor sets including a first conductor set adjacent a second conductor set. Each conductor set includes one or more insulated conductors. The cable further includes first and second shielding films disposed on opposite sides of the cable forming cover portions and pinched portions, where the cover portions substantially surround each conductor set, and the pinched portions form pinched portions of the cable on each side of each conductor set. The insulated conductors in a conductor set are not in a same geometrical plane. A first insulated conductor of the first conductor set is nearest the second conductor set. A second insulated conductor of the second conductor set is nearest the first conductor set. The first and second insulated conductors have a center-to-center spacing S. The first insulated conductor has an outer dimension D1 and the second insulated conductor has an outer dimension D2. S/Dmin is in a range from 1.

  • Patent number: 8575491
    Abstract: A shielded electrical cable is disclosed that includes a plurality of spaced apart conductor sets where each conductor set includes one or more insulated conductors. The cable further includes first and second shielding films that include concentric portions, pinched portions, and transition portions arranged such that the concentric portions are substantially concentric with one or more end conductors of each conductor set, the pinched portions form pinched portions of the cable on two sides of the conductor set, and the transition portions provide gradual transitions between the concentric portions and the pinched portions. The cross-sectional areas of the transition portions are less than the cross-sectional areas of the conductors. The radius of curvature of the shielding films in the transverse direction is at least 100 microns.
