  • Patent number: 9799426
    Abstract: An electrical ribbon cable (110) includes an insulated conductor (114) extending along a longitudinal axis of the cable. The cable also includes a shielding film (116) that carries the insulated conductor (114). The shielding film (116) has a variable thickness defining a thickened rib portion (117) and a thinned connecting portion (118), these portions being electrically conductive and extending along the longitudinal axis. The insulated conductor (114) is disposed proximate the rib portion (117). The insulated conductor (114) may be one of multiple insulated conductors that are organized into multiple conductor sets (112) including at least a first and second conductor set, each conductor set (112) including one or more of the insulated conductors (114), and the rib portion (117) may be disposed between the first and second conductor sets.

  • Publication number: 20170213622
    Abstract: A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.
