Method of producing multiconductor cable harness

A method of producing at least one multiconductor cable that comprises a plurality of wires having an intermediate portion and transforming portions located between each of the ends of the cable and the ends of the intermediate portion,

• the method comprising the steps of:
• (a) preparing an arranging tool having a flat arranging surface provided with at least one wire-holding-groove-forming portion having a plurality of wire-holding grooves arranged in a flat array on the flat arranging surface with different lengths from a minimum length of Lsa to a maximum length of Lma, the lengths being varied successively;
• the at least one wire-holding-groove-forming portion being provided with an intermediate-portion arranging section having grooves with different lengths varying successively and transforming-portion-arranging sections having grooves parallel with one another and locating at both ends of the intermediate-portion-arranging section;
• (b) placing a plurality of wires into the wire-holding grooves;
• (c) attaching an adhesive tape or a member having a similar function to the transforming portions of the wires so that the arranged state can be maintained;
• (d) removing the wires from the arranging tool with maintaining the arranged state;
• (e) forming a terminal structure in which the plurality of wires are arranged in a specific pitch for electrical connection at both ends of the wires;
• and
• (f) bundling the intermediate portions of the wires together.
