Definitions

  • This invention relates to electrical wiring conduit and more particularly to wiring conduit for automobile wire harnesses.
  • the various electrical components of the vehicle are electrically connected to the battery by electrical leads or wires grouped or bundled together to form what is commonly termed a wire harness.
  • the harness is housed in a wiring conduit.
  • harness conduit is a plastic corrugated tube which is axially slit throughout its length. This tube is corrugated along the longitudinal axis so as to be very flexible. The corrugated tube is versatile in that it can be readily bent for installation and the axial slit allows electrical leads to be routed out from the harness at any location along the tube.
  • Such tubes are disclosed in Nestor, U.S. 4,384,167 and Ghirardi et al., U.S. 3,711,633. Corrugated tubes are not satisfactory however where the harness conduit must actually support the wiring harness.
  • a C-channel conduit In applications where the harness conduit must support the wire harness, a C-channel conduit is commonly utilized.
  • This type of conduit basically comprises two elongated C-section pieces which are mated together about the wire harness so as to form a conduit and are secured by wrapping tape or the like.
  • the C-channel sections are rigid plastic members that necessitate a segmented conduit configuration when some flexing is required in routing the wire harness in the automobile body.
  • the rigid tube sections (formed from the C-channel sections) are butted end to end with each other and secured with tape so as to function as a joint and provide a degree of flexing, i.e., the annular "break" between the tube sections forms a flexible joint.
  • Trough conduit is an extruded tubular member which is slit longitudinally end-to-end so that one longitudinal edge overlaps the opposing longitudinal edge to compress or adjust about the wire harness. Similar to the C-channel conduit, trough conduit is utilized in separate sections butted end-to-end to obtain flexing and for routing out wire groups from the wire harness.
  • It is an object of the present invention provide a new and improved wire harness conduit.
  • Another object of the invention is to provide a unitary harness conduit with preformed flexible points, take-out apertures and mounting apertures positioned to correspond to the respective wire harness.
  • Another object of the invention to provide a harness conduit which has predetermined flexible points and is able to support a wire harness.
  • a further object of the invention is to provide such a conduit which minimizes cross-sectional size of the wire harness assembly. .
  • a further object of the invention is to provide such a conduit which is economical to manufacture and convenient and efficient to assemble to the wire harness.
  • Another object of the invention is to provide a wire harness assembly which facilitates installation into the automobile body by precise positioning of flexible points, wire harness take-outs, and mounting connectors. Accordingly, it has been found that the above-noted disadvantages in the prior art are overcome and the foregoing objects are attained in an automobile wiring harness conduit having a unitary tubular wall member of resilient material forming a longitudinal wire passage for housing the wire harness.
  • the tubular wall member has first and second rigid sections for supporting the wire harness and a third interconnecting section.
  • the third section is configured so as to be flexible to permit non-aligned relative positioning of the first and second section.
  • the third flexible section is corrugated along its longitudinal axis so as to be flexible in directions transverse to the longitudinal axis.
  • the tubular member has an end-to-end longitudinal slit defining opposed longitudinal edges and is configured so that one longitudinal edge is biased to overlap the other longitudinal edge and fit snugly about the wire harness.
  • the rigid sections of the tubular wall member have take-out apertures for routing wires from a wire harness and mounting apertures to receive connectors for mounting the conduit to an automobile body.
  • the flexible section, the take-out apertures and the mounting apertures are preformed and positioned to accurately correspond to the wire harness and predetermined routing pathway in the vehicle body.
  • Figure 1 is a perspective view of an automobile wiring harness assembly including the harness conduit of the present invention.
  • Figure 2 is an enlarged perspective view partly broken away of the conduit of the present invention.
  • Figure 3 is a sectional view seen on line 3-3 of Figure 2.
  • Figure 4 is a perspective view of the wiring conduit of Figure 1 rotated 180*.
  • an automobile wiring harness assembly is shown generally comprising a conventional automobile wiring harness 10 and a wiring conduit 12 mounted thereto.
  • the wiring harness 10 generally comprises a plurality of electrical leads 14 bundled together by tape 16 or the like to form an elongated relatively ' compact bundle of wires extending generally longitudinally between ends 18,20.
  • individual groups of wires 22,24 are routed from the wire harness between the ends 18,20 for connection to respective electrical circuits in the automobile.
  • the wire harnesses include a plurality of varied electrical connectors and circuit components (not shown) .
  • a plurality of mounting connectors (not shown) are secured to the wire harness by tape or the like.
  • a common type of mounting connector is a push-on plastic connector referred to as a Christmas tree connector.
  • the mounting connectors are relatively positioned on the wire harness to correspond to the positioning of the preformed mounting recesses in the vehicle body. Further detail of wiring harness 10 is not required for purposes of description of the present invention.
  • the wiring conduit 12 of the present invention is a unitary tubular wall member of resilient plastic material forming a longitudinal wire passageway between opposite ends 26,28.
  • the conduit 12 has a rigid elongated central section 30 connected to opposite rigid end sections 32,34 by flexible sections 36,38, respectively.
  • the flexible section 36 is corrugated along its longitudinal axis so as to provide a degree of flexibility in directions transverse to the longitudinal axis so as to allow the sections 30,32 to be moved into non-aligned positions.
  • Other known flexible configurations may be utilized for section 36 depending upon the degree of flexibility required for the particular routing path of the wiring harness.
  • the flexible section 38 is identical to section 36.
  • the end section 32 has a take-out aperture or notch 40 for routing the wire group 24 out from the wire harness 10.
  • the central section 30 has a take-out aperture 42 to take out the wire group 22 from the wiring harness 10.
  • the take-out apertures 40,42 are precisely positioned so that the respective take-out leads 24,22 are accurately located for routing along a predetermined path in the vehicle body upon installation.

  • the conduit 12 has an axial slit 45 end-to-end so as to define overlapping edge sections 46,48 as seen in Figure 3.
  • the conduit 12 is configured to bias the edge sections 46,48 to overlap so as to tend to compress or adjust about the wire harness 10. In this manner, the conduit 12 is self-adjusting to the diameter of the wire harness 10 to minimize the diameter of the wiring harness assembly for ease of routing and conservation of space when installed in the automobile body.
  • the conduit 12 is dimensioned and configured for a particular wiring harness and routing path in the respective automobile body.
