Description

  The present invention relates to a wire harness routed to an automobile or the like as a moving body.

  Various electronic devices are mounted on automobiles or the like as moving bodies. In order to transmit electric power from a power source such as a battery, a control signal from a control device, and the like to the electronic device, the automobile is wired with a wire harness. The wire harness includes a plurality of electric wires and a connector attached to an end portion of the electric wires.

  The plurality of electric wires are bundled around a tape. In addition, a plurality of electric wires bundled with tape are attached with wiring clips or the like for fixing the wire harness to the vehicle body panel of the automobile. The connector is connected to a connector of an electronic device. The wire harness transmits electric power and various signals to the electronic device.

  Such a wire harness is routed in a place where it is difficult for the occupant of the moving body to visually recognize the wire harness. For example, the wire harness laid in the engine room may be visually recognized by the occupant. For this reason, the above-described tape or the like is darkened, that is, a color with low lightness such as black or gray so that the wire harness is not noticeable as much as possible.

  By the way, in recent years, in order to improve the recyclability of automobiles, separate collection for each part material is required at the time of car dismantling such as when a car is scrapped. Such an automobile dismantling operation is performed using a heavy machine such as a nibra in a covered factory, for example. The above-described wire harness is, for example, gripped by a sandwiching portion of a heavy machine and peeled off from a vehicle body panel (for example, see Patent Documents 1 and 2).

  Hereinafter, the wire harness 1 concerning the 1st Embodiment of this invention is demonstrated with reference to FIG. The wire harness 1 shown in FIG. 1 etc. concerning the 1st Embodiment of this invention is attached to the panel 6 (corresponding to a to-be-routed part. It shows with a dashed-dotted line in FIG. 1 etc.) of a motor vehicle as a moving body. , Routed in the car.

  The panel 6 constitutes the vehicle body. The panel 6 has a plurality of holes (not shown) through which the wiring clips attached to the wire harness 1 are locked.

  As shown in FIG. 1, the wire harness 1 includes a plurality of electric wires 2 and a fluorescent tape 3 as a light emitting member. Each electric wire 2 is a covered electric wire provided with a conductive core wire and an insulating covering portion. The core wire is formed by twisting a plurality of strands made of copper or the like. Moreover, the core wire may be comprised with one strand. The covering portion is made of an insulating synthetic resin and covers the core wire. The covering portion is made of a synthetic resin that exhibits a dark color (indicated by rough dots in FIG. 1 and the like) under visible light. In addition, the dark color in this specification shall mean colors with low brightness, such as black and gray. A connector (not shown) is attached to the end of the electric wire 2 or the like.

  As shown in FIG. 2, the fluorescent tape 3 includes a strip-shaped base material 31 made of a synthetic resin, an adhesive layer 32 that is provided on one surface of the base material 31 and adheres to a covering portion of the electric wire 2, And a light emitting layer 33 provided on the other surface of the material 31. The base material 31 is colored in dark color by mixing a dark colorant into the synthetic resin. The adhesive layer 32 is formed by applying a known adhesive (pressure-sensitive adhesive).

  The light emitting layer 33 is formed by applying a paint containing a known fluorescent pigment. The light emitting layer 33 is colorless or light-colored under visible light, and emits light when irradiated with ultraviolet rays UV using a black light 8 described later. For this reason, the fluorescent tape 3 exhibits a dark color (indicated by fine dots in FIG. 1) that is the color of the base material 31 under visible light, emits light when irradiated with ultraviolet rays UV, and has a higher brightness than the dark color (see FIG. 3 and FIG. 4). As such a fluorescent tape 3, a corresponding commercial product can be used. In FIG. 1 and the like, for the sake of convenience, the dark color of the fluorescent tape 3 and the dark color of the covering portion of the electric wire 2 are indicated by dots of different fineness, but these do not necessarily have to be different colors.

  The fluorescent tape 3 described above is wound directly around a plurality of collected electric wires 2 and bundles these electric wires 2. The fluorescent tape 3 is spirally wound around the plurality of electric wires 2 and is wound around a part of the electric wires 2 in the longitudinal direction. The said part is a part which wants to make the wire harness 1 light-emit, for example, the part (namely, part which is easy to be visually recognized by an operator at the time of a car dismantling) wired in the engine room or trunk room of the wire harness 1; The part etc. to which the clip for wiring of the wire harness 1 is attached are mentioned.

  Moreover, the wire harness 1 is peeled off from the panel 6 by using a heavy machine 7 such as a nibler in a factory with a roof, for example, when the automobile is disassembled. Since the factory can accommodate heavy machinery 7, the ceiling is high and the interior is relatively dark.

  As shown in FIG. 3, a clamping unit 70 is attached to the tip of the arm of the heavy machine 7. The clamping unit 70 includes a fixed tooth 71 attached to the arm so as to be rotatable about the axial direction of the arm, and a movable tooth 72 attached to the fixed tooth 71 so as to be able to contact with and separate from the fixed tooth 71. ing. The sandwiching unit 70 sandwiches the wire harness 1 between the fixed tooth 71 and the movable tooth 72.

  A black light 8 as an ultraviolet irradiation device is attached to the fixed tooth 71 of the heavy machine 7. As the black light 8, a well-known one can be used, but it is preferable that the black light 8 is capable of irradiating the ultraviolet light UV having such a wavelength that the fluorescent tape 3 emits light bright enough to be visually recognized from the driver's seat of the heavy machine 7. The black light 8 may be attached to a stand or the like and installed on the factory floor, or may be provided on the factory ceiling to irradiate the entire factory with ultraviolet UV.

An operator can easily see the wire harness 1 from the driver's seat of the heavy machine 7. Thereafter, the heavy machine 7 is operated, and the portion around which the fluorescent tape 3 is wound is sandwiched between the sandwiching portions 70 as shown in FIG. Thus, the wire harness 1 is removed from the panel 6.

  According to this embodiment, since the fluorescent tape 3 emits light when the wire harness 1 is irradiated with ultraviolet rays UV, the wire harness 1 can be easily visually recognized. Therefore, the removal work of the wire harness 1 can be efficiently performed in a shorter time, and the recyclability can be improved by reducing the remaining of the wire harness 1.
