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.

Abstract: A coaxial cable is composed of a conductor, an insulator covering a periphery of the conductor, a shield layer covering a periphery of the insulator, and a sheath covering a periphery of the shield layer. The shield layer is configured to include a lateral winding shielding portion with a plurality of metal wires being helically wrapped around the periphery of the insulator, and a batch plating portion made of a hot-dip plating covering respective peripheries of the lateral winding shielding portion. The shield layer includes a joining portion where the metal wires adjacent to each other in a circumferential direction are joined with each other with the batch plating portion at a spaced portion where the adjacent metal wires are spaced apart from each other, and the non-joining portion where the metal wires adjacent to each other in the circumferential direction are not joined with each other with the batch plating portion at the spaced portion. A length of the non-joining portion along a cable longitudinal direction is shorter than a winding pitch of the lateral winding shielding portion.

Abstract: 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 σ1, the center-to-center spacing of the insulated conductors of the second conductor set is σ2, and σ1/σ2 is greater than 0.7.

Abstract: A cable includes a first metal conductor, a first insulator, a second metal conductor and a second insulator. The first insulator is at least partially wrapped on the first metal conductor. The second insulator is at least partially wrapped on the second metal conductor. The first metal conductor is adapted to transmit a first signal. The second metal conductor is adapted to transmit a second signal. The cable also includes an intermediate layer material at least partially wound on the first insulator and the second insulator. A dielectric constant of the intermediate layer material is lower than that of the first insulator, and the dielectric constant of the intermediate layer material is lower than that of the second insulator. With this arrangement, the cable of the present disclosure is capable of realizing low mode conversion and improving the high frequency characteristics.

Abstract: Ribbon cables including a plurality of spaced apart substantially parallel conductors extending along a length of the cable and arranged along a width of the cable, and first and second insulative layers disposed on opposite sides of and substantially coextensive with the plurality of conductors along the length and width of the cable are described. Each insulative layer may be adhered to the conductors and may include alternating substantially parallel thicker and thinner portions extending along the length of the cable. The thicker portions of the first and second insulative layers are substantially aligned in one to one correspondence. Each corresponding thicker portion of the first and second insulative layers have at least one conductor in the plurality of conductors disposed therebetween. The thicker portions may have an effective dielectric constant less than 2.
