The disclosure generally relates to nested shielded ribbon cables that form an electrical cable assembly. The electrical cable assembly includes features that can facilitate bending and movement of the cable.

A shielded electrical cable includes one or more conductor sets extending along a length of the cable and being spaced apart from each other along a width of the cable. Each conductor set has one or more conductors having a size no greater than 24 AWG and each conductor set has an insertion loss of less than about 20 dB/meter over a frequency range of 0 to 20 GHz. First and second shielding films are disposed on opposite sides of the cable, the first and second films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second films in combination substantially surround each conductor set, and the pinched portions of the first and second films in combination form pinched portions of the cable on each side of each conductor.

A shielded electrical cable includes a conductor set and two generally parallel shielding films disposed around the conductor set. The conductor set includes one or more substantially parallel longitudinal insulated conductors. The shielding films include a parallel portion wherein the shielding films are substantially parallel. The parallel portion is configured to electrically isolate the conductor set.

A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is 1, the center-to-center spacing of the insulated conductors of the second conductor set is 2, and 1/2 is greater than 0.7.

A shielded electrical cable (50) includes conductor sets (51a, 51b) spaced apart along a width of the cable and extending along a length of the cable. Each conductor set includes first and second insulated conductors (52a, 52b), one or two drain grounding wires (54) disposed between the first and second insulated conductors, first and second conductive shielding films (56a, 56b) disposed on opposite first and second sides of the conductor set, and an adhesive layer (59) bonding the first shielding film to the second shielding film.

An electrical cable includes at least one conductor assembly. Each conductor assembly includes at least one inner conductor that extends along a length, an insulator, and a shield layer. The insulator engages and surrounds a surface of the at least one inner conductor. The insulator is composed of a dielectric material. The shield layer engages and surrounds an outer perimeter of the insulator. The shield layer is formed of a conductive plastic material to provide electrical shielding for the at least one inner conductor and flexibility.
