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.

A differential signal transmission cable includes an insulated wire including a pair of differential signal transmission conductors coated with an insulation, a shield tape conductor made of a band-like member including an electrically conductive metal layer, and wrapped along an outer surface of the insulated wire so that its ends in a width direction are overlapped together, a first resin tape spirally wound along an outer surface of the shield tape conductor and around an outer side of the shield tape conductor, and a second resin tape spirally wound along an outer surface of the first resin tape and around an outer side of the first resin tape. The shield tape conductor, the first resin tape and the second resin tape are wound in a same circumferential direction around a center axis of the insulated wire.

A cable bypass assembly is disclosed for use in providing a high speed transmission line for connecting a board mounted connector of an electronic device to a chip on the device board. The bypass cable assembly has a structure that permits it, where it is terminated to the board mounted connector and the chip member, or closely proximate thereto to replicate closely the geometry of the cable. The connector terminals are arranged in alignment with the cable signal conductors and shield extensions are provided so that shielding can be provided up to and over the termination between the cable signal conductors and the board connector terminal tails. Likewise, a similar termination structure is provided at the opposite end of the cable where a pair of terminals are supported by a second connector body and enclosed in a shield collar. The shield collar has an extension that engages the second end of the cable.

Cables including central insulators and/or center separators. Each of at least some of the central insulators includes a first wire channel configured to receive a first wire of a wire pair, a second wire channel configured to receive a second wire of the wire pair, and an intermediate portion positioned between the first and second wire channels. Each of at least some of the center separators includes a longitudinally extending central portion as well as first, second, third, and fourth portions extending outwardly from the central portion. Optionally, the first, second, third, and/or fourth portions may include laterally extending through-holes. Optionally, the central, first, second, third, and/or fourth portions may include an air-filled longitudinally extending channel. Central insulators for use with coaxial cables and cables that conduct three-phase signals are also provided. Methods of forming central insulators are also described.

A shielded electrical cable includes a conductor set, two generally parallel shielding films disposed around the conductor set, and a transition portion defined by the shielding films and the conductor set. The conductor set includes one or more substantially parallel longitudinal insulated conductors. The shielding films include a concentric portion substantially concentric with at least one of the conductors and a parallel portion wherein the shielding films are substantially parallel. The transition portion provides a gradual transition between the concentric portion and the parallel portion of the shielding films.
