A ribbon cable includes a plurality of cable groups arranged side by side in a width direction of the ribbon cable and a wrapping film continuously wound on an outer side of the cable groups in a multi-turn wrapping manner at an inclined angle with respect to the width direction. There is a gap between every adjacent pair of cable groups.

A plurality of wire-like transmission members is easily fixed to a base member. The wiring member includes an assembled wire made up of a plurality of bundled wire-like transmission members and a base member in which the assembled wire is fixed on the main surface.

An electronic wire and a cable which are excellent in bending resistance even when a diameter is small. The electronic wire has a conductor and a resin insulating layer coated on the conductor. The conductor is a double twisted wire in which twisted wires formed by twisting a plurality of wires are twisted, a diameter of the wire is 0.05 mm or more and 0.2 mm or less, a cross-sectional area of the conductor is 1.0 mm.sup.2 or more and 3.0 mm.sup.2 or less, a breaking elongation of the conductor is 10% or more and 17% or less, a tensile strength of the conductor is 200 MPa or more and 400 MPa or less, and the insulating layer is disposed to be in close contact with the conductor and has a solid structure.

A wire harness including: a core wire having a flat straight section whose vertical height is smaller than a width thereof and a bend bent from an end of the straight section, wherein: the straight section is formed from a second assembled wire obtained by twisting or braiding together first assembled wires which are each obtained by twisting or braiding wire strands, and the bend is formed from a plurality of adjacent wires arranged adjacently in a direction orthogonal to a vertical direction.

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.

The present invention relates to data cable and methods of installing/building data cable. The cable disclosed herein is indoor/outdoor and can be configured as 4-twisted pair, or any of the numerous other types of data cable. In one embodiment, we disclose an electrical data cable comprising a plurality of insulated wires wherein the plurality of insulated wires is coupled for a first portion of the length of the data cable so as to form at least one twisted pair of wires; the plurality of insulated wires is configured in a flat, planar arrangement for a second portion of the data cable; and the plurality of insulated wires is coupled for a third portion of the length of the data cable so as to form at least one twisted pair of wires. In an alternate method, we disclose a method of attaching a connector to the electrical data cable comprising the steps of cutting the data cable at the untwisted segment and attaching a connector to the plurality of insulated wires in the untwisted segment.
