  • Publication number: 20030217860
    Abstract: To mount a knob 10 onto a wire harness, at first, a belt portion 14 of the knob 10 is wound around the wire harness and an eye portion of the knob 10 is inserted through an elongated hole 20 formed in a base portion 12 of the knob 10. Next, tape is wound around not only the wire harness and the two end portions of the base portion 12 to thereby fix the base portion 12 to the wire harness. When dismantling a vehicle, a hook mounted on the leading end of a wire rope secured to a clamper of a crane truck is secured to a circular eye 18 formed in the knob 10 and, after then, the wire harness is raised up by the crane truck.

  • Patent number: 5526549
    Abstract: A grommet comprising: a panel mounting portion which is mounted on an opening of a panel and has a large-diameter hole for loosely receiving a wiring harness; a wire receiving portion which is formed axially integrally with the panel mounting portion and has a small-diameter hole for closely receiving the wiring harness; the large-diameter hole being communicated with the small-diameter hole such that the wiring harness is inserted through the small-diameter hole and the large-diameter hole in an insertion direction oriented from the small-diameter hole to the large-diameter hole; and a plurality of ribs which are provided in the large-diameter hole so as to extend in parallel with the insertion direction of the wiring harness.

  • Patent number: 4357070
    Abstract: An electric connector comprising a pair of interlocking crimp-type terminals having bolt holes in flat contact portions which are brought into concentric relationship when the terminals are locked by means of interlocking lugs each extended from the outer circumference of each terminal. The bolt hole of one or a large terminal has a pair of diametrically opposite notches so that the flat contact portion of the other or a small terminal is partially inserted into the hole of one terminal in such a way that the flat contact portions of the terminals overlap each other with the concentric bolt holes and the interlocking lugs engage with each other, preventing the displacement of the terminals.
