A multicore ultrafine coaxial wire is formed by consolidating a plurality of ultrafine coaxial wires in a flat array. Each of the ultrafine coaxial wires has a center conductor, whose tip portion is exposed, an insulating layer, an outer conductor, and a covering. The harness has a grounding member that connects in common the outer conductors of the multicore ultrafine coaxial wire and an insulator frame that fixes the center conductors. End portions of an underside film and end portions of a topside film both of the insulator frame are provided with an alignment hole to align the center conductors with circuits on a substrate.

Ultrafine-coaxial-wire harness, connecting method thereof, circuit-board-connected body, circuit-board module, and electronic apparatus

A method of producing a multiconductor cable is provided herein. A plurality of wires are arranged in a flat array with a specific pitch at both ends of them having an intermediate portion that are bundled together and a transforming portion. The plurality of wires have lengths different from one another, where the lengths vary successively from the minimum length, Ls, to the maximum length, Lm. At both end portions, the transforming portion of the wires are arranged using an arranging tool and attached so that the wires are held in grooves. The wires are moved from the arranging tool and a terminal structure is formed for electrical connection at both ends of the multiconductor cable.

Method of producing multiconductor cable harness

A multiconductor cable is reduced in the possibility of break even for use at a place where the cable undergoes twisting, and a method can produce the multiconductor cable easily at a low cost. The multiconductor cable incorporates a plurality of wires that are arranged in a flat array with a specific pitch at both ends of them, that have an intermediate portion at which they are bundled together; and that have lengths different from one another, the lengths varying successively from the minimum length, Ls, to the maximum length, Lm. The multiconductor cable satisfies the formulae 'D/E&#x3e;&#x2159;,' and '(Lm&#x2212;Ls)&#x3e;{(D+E)&#x2212;E},' where D is the width of the cable at both ends, E is the distance between the ends of the cable, Lm is the maximum length, and Ls is the minimum length.
