  • Patent number: 5694678
    Abstract: A family of retainer clip holders can each be adjusted to properly position a retainer clip at a desired location on a wire harness. In the past, it has sometimes been complicated to properly position a retainer clip holder relative to the base, and mount the holder base on a jig for assembling wire harnesses. There have typically been too many fixtures required on the jig. Thus, the prior art has attempted to assemble the retainer clips by individually tailoring hundreds of retainer clip holders for the particular orientation demanded by the particular retainer clip application. The inventive family of retainer clip holders allows the selection of the proper adjustable retainer clip holders and the adjustment of that retainer clip holder to accommodate the particular retainer clip application demanded. In this way, the invention replaces the hundreds of previously required holders with seven basic tools.

  • Patent number: 5483738
    Abstract: Disclosed is an improved wire measuring apparatus comprising a wire guide roller mechanism 3 and a looper 5 to push down a fed wire to a descending position, thereby measuring the length of wire in terms of descending position at which the wire is held by the looper 5. The wire guide roller mechanism 3 comprises a frame, first, second and third guide rollers 6, 7 and 8 rotatably fixed to the frame. The first and third guide rollers 6 and 8 rotate in same direction, and the second guide roller 7 rotates in an opposite direction both in pulling the wire forward and backward. Also, the whole guide roller arrangement is designed to incline and follow the increasing or decreasing inclination of wire length ahead of the third guide roller. Thus, the wire curling inclination can be reduced from the measured wire. The second guide roller acts to reduce the effect of the wires bending around the first guide roller and the wires extend tangentially from the third guide roller.

  • Patent number: 5473811
    Abstract: Disclosed is an apparatus 1 for removing insulation from wire 5 where the insulation 21 surrounds a wire core 20. This apparatus 1 includes a mounting fixture 3 for holding a spool 4 of wire 5 in a manner that enables the wire to be unwound from the spool. As the wire 5 is continually unwound from the spool 4 it is wound around a conically shaped, rotatable mandrel 7. A manually adjustable knife blade 23 disposed between the mounting fixture 3 and the mandrel 7 engages the wire 5 as the wire is unwound from the spool 4 and wound around the mandrel. The knife blade 23 is positioned essentially at a tangent to the wire core 20 so that it cuts the insulation 21 into sections, one section 43 riding over the blade as the wire 5 is wound around the mandrel 7 and the other section 44 of insulation remaining on the wire core after the wire engages the knife blade.

  • Patent number: 5282311
    Abstract: A wire-travelling path between feed rollers 111 and an intermediate stripping unit 200 is set by an adjusting unit 100 disposed therebetween so that the distance of a wire 50 from a cutting-off position of cutters 141 to a cutting-into position of cutters 202 is equal to the sum of the length of the cutting-off wire and the distance from the end of the cutting-off wire to one end of the intermediate stripped area of the wire. If the wire 50 is fed by the length to be cut off, the wire 50 can be positioned simultaneously at the cutters 141 and 202. Consequently, it is possible to carry out only one time of feeding and resting of the feed rollers 111 in a cycle of operation and to reduce the rest period from the time when the feed rollers rest to the time of a following treatment, thereby producing a harness efficiently.

  • Patent number: 5252550
    Abstract: The present invention relates to a method of producing a superconducting composite wire. The method comprises forming a continuously supplied metal or metal alloy strip into a flume-shaped strip. A ceramic copper oxide superconducting powder material is filled in the interior of the flume-shaped strip. The flume-shaped strip is rolled such that a first edge of the strip approaches a second edge of the strip to form a tubing having a gap between the first and second edges and also having the powder material enveloped therein. The gap allows free access of oxygen to the powder material during a subsequent sintering step. The powder material is then sintered at a temperature of between 0 and 100.degree. C. less than the lowest melting point of any constituent of the material. The strip enveloping the sintered material is then deformed to a reduced cross-section and subjected to a heat treatment.
