Abstract
Abstract A method for assembling electrical wire harnesses of the type used to interconnect electrical components on aircraft is initiated by applying identifying indicia to several portions of a continuous wire and marking the termination point of each of the wire portions in a predetermined sequence along the continuous wire. The continuous strand is then respooled and placed on a numerically controlled wire laydown machine. The machine lays down the individual wire portions in a predetermined sequence along a predetermined path on a formboard prepared for that purpose. The machine also severs the continuous wire to produce individual wires as they are being laid on the formboards. Means are provided on the formboard for holding individual wire ends at a predetermined location on the formboard near the termination point for the predetermined wire paths. Certain of the individual wire ends are retained on the formboard in several groupings each of which is in an ordered array. The several groups of wires are then tied together a spaced distance from the ends of the groups, forming a harness skeleton. Wire order retention devices are then applied to the individual wires in a grouping to retain the ordered array of the segment end when the harness skeleton is removed from the formboard. Thereafter the individual wires are removed from the formboard and identifying indicia applied to each of the groupings. Thereafter, the harness skeleton is taken to another processing zone in which electrical insulation is stripped from the ends of the individual wires and pin-type connector contacts are applied or fastened to the wire ends. The pin-type contacts are inserted into preselected sockets in a multi-plug type connector by selecting an individual wire from a particular wire order retention device and inserting it into the appropriate socket. Thereafter subsequent wires are removed from the wire order retention device in the predetermined order and inserted into preselected sockets in the connector. The harness and an appropriate subassembly, if any, are then placed on a test apparatus to determine quality, continuity and correctness of assembly of the wire harness. Thereafter the wire harness and subassembly if any can be installed on an aircraft.
