Definitions

  • the present invention relates to a wire harness.
  • a wire harness having an outer conductor for shielding electromagnetic waves is well known.
  • the outer conductor has a substantially cylindrical conductor tube made of aluminum, for example.
  • Conductor tubes made of aluminum have high rigidity. Therefore, if the mounting space is narrow, the wire harness may not be able to be placed because the conductor tube limits the position.
  • Patent Document 2 discloses a wire harness using a braided shield.
  • This wire harness has a water stop valve that fills the gap between the electric wire and the grommet.
  • the braided shield is arranged to cover the outer periphery of the water stopcock.
  • a waterproof adhesive member is attached to the outer peripheral surface of the braided shield.
  • the braided shield is flexible. Therefore, if the mounting space is narrow, the wire harness can be bent and placed. Therefore, if the wire harness of Patent Document 2 is adopted, the wire harness can be mounted even if the mounting space is narrow.
  • An object of the present disclosure is to provide a wire harness that can improve water-stopping properties.
  • a wire harness that solves the above problem includes an electric wire for transmitting electricity, a grommet that is attached to an opening through which the electric wire is passed, and in which the electric wire is housed, and a grommet that is provided for water-stopping the inside of the grommet.
  • a water stop valve through which the electric wire is attached a shield material attached around the water stop valve, and a shield material attached to the outer periphery of the shield material, so that the shield material is tightly attached to the water stop valve.
  • a second adhesion layer that is attached to the outer periphery of the first adhesion layer to make the first adhesion layer adhere to the shield material.
  • the present disclosure can improve the water-stopping properties of a wire harness.
  • FIG. 1 is a perspective view of the wire harness.
  • FIG. 2 is a front view of the wire harness.
  • FIG. 3 is an exploded perspective view of the wire harness.
  • FIG. 4 is a cross-sectional view taken along the line IV--IV shown in FIG.
  • FIG. 5 is a sectional view taken along the line VV shown in FIG.
  • FIGS. 6(a) to 6(d) are procedural diagrams showing the flow of manufacturing a wire harness.
  • FIG. 7 is an operational diagram of the wire harness.
  • FIGS. 8(a) to 8(d) are procedural diagrams showing the flow of manufacturing a wire harness.
  • the first adhesive layer brings the shield material into close contact with the water stopcock
  • the second adhesive layer brings the first adhesive layer into close contact with the shield material.
  • the grommet includes an assembly including the water stopcock, the electric wire, the shield material, the first adhesive layer, and the second adhesive layer inside. It has a cylindrical portion to accommodate the cylindrical portion, and a seat portion that supports the base end of the cylindrical portion. According to this configuration, the wire harness can easily undergo a shape change in which the cylindrical portion is bent from the seat portion. Therefore, it becomes possible to make the wire harness easy to bend.
  • the grommet 5 is disposed, for example, at a portion of the attachment point 3 that separates indoor and outdoor areas.
  • the tubular portion 6 of the grommet 5 is disposed on the indoor side, and the seat portion 8 is disposed on the outdoor side.
  • the proximal end 7 of the grommet 5 is provided with a recess 7a that facilitates bending of the grommet 5.
  • the assembly 22 includes, for example, a water stopcock 23, a shield material 24, a first adhesive layer 25, and a second adhesive layer 26.
  • the assembly 22 is housed in the cylindrical portion 6 of the grommet 5. The assembly 22 prevents fluids such as water from entering the grommet 5.
  • the second adhesion layer 26 is attached to the outer periphery of the first adhesion layer 25 to bring the first adhesion layer 25 into close contact with the shield material 24 .
  • the second adhesive layer 26 is, for example, a tape 35 wound a plurality of times while shifting its position along the axial direction of the electric wire 2 (Z-axis direction in FIG. 5).
  • the tape 35 preferably has high flexibility, high insulation, heat resistance, and cold resistance.
  • the tape 35 is, for example, a vinyl tape.
  • the grommet 5 has an annular seal portion 38 on its inner surface that seals the gap between the grommet 5 and the second adhesive layer 26.
  • a plurality of seal portions 38 are formed at equal intervals along the axial direction of the electric wire 2 (Z-axis direction in FIG. 5).
  • the seal portion 38 is, for example, a protrusion that protrudes from the inner surface of the grommet 5 by a predetermined amount.
  • the seal portion 38 is, for example, a lip-type seal that assumes a sealed state by elastically deforming.
  • the mounting space for the wire harness 1 may be small.
  • an example is given in which the height of the mounting space is low.
  • the wire harness 1 can be bent and arranged.
  • the first adhesion layer 25 and the second adhesion layer 26 are also bendable, bending of the wire harness 1 is facilitated. In this way, it is possible to have flexibility in the posture (tilt) of the wire harness 1, so even if the mounting space is small, the wire harness 1 can be arranged.
  • the first adhesive layer 25 tightly adheres to the shield material 24 by wrapping the second adhesive layer 26 around it. That is, in order to prevent a gap from forming between the shield material 24 and the first adhesive layer 25, the second adhesive layer 26 is wrapped around the outer periphery of the first adhesive layer 25. Therefore, the water-stopping property between the shield material 24 and the first adhesive layer 25 is further improved.
  • the first adhesive layer 25 brings the shield material 24 into close contact with the water stopcock 23 and the second adhesive layer 26 brings the first adhesive layer 25 into close contact with the shield material 24.
  • the two layers, the first adhesion layer 25 and the second adhesion layer 26, bring the members into close contact with each other, it is possible to make it difficult to create gaps between the members. Therefore, in the bendable wire harness 1, water-stopping properties can be improved.
  • the grommet 5 has an annular seal portion 38 on its inner surface that seals the gap between the grommet 5 and the second adhesive layer 26 . According to this configuration, the water-stopping property between the grommet 5 and the second adhesive layer 26 can be improved.
  • the second adhesive layer 26 is not limited to the tape 35, and may be, for example, a cylindrical member that covers the first adhesive layer 25 from the periphery.
  • the stopcock 23 is not limited to a rubber stopper, but may be made of an elastic material. In this way, the stopcock 23 only needs to be made of a material that can seal the inside of the grommet 5.
  • the grommet 5 may be directly attached to the attachment point 3, for example, to the body of the vehicle, without using the bracket 9. - The grommet 5 may have any shape as long as it can protect the electric wire 2 passed through the hole 27.
