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 wiring clip or the like for fixing the wire harness to a panel constituting the vehicle body of the automobile is attached to these electric wires. 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 covering part etc. of an electric wire are made into the dark color, ie, the color with low brightness, such as black and gray, and the wire harness is made as inconspicuous 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 pulled off from an automobile panel (see, for example, Patent Documents 1 and 2).

JP 2007-174750 A JP 2004-224253 A

  However, as described above, the wire harness is routed in a place where it is difficult for an occupant to visually recognize, and the covering portion of the electric wire is made dark so as to be inconspicuous as much as possible. Furthermore, the factory where the dismantling work is performed can accommodate heavy machinery, so the ceiling is high and the interior is relatively dark. For this reason, it was difficult for an operator to visually recognize the wire harness from the driver's seat of the heavy machinery, and it was difficult to remove all the wire harnesses from the panel, and there was a problem that the recyclability was poor. For example, there is a problem that the recovery rate of copper or the like constituting the electric wire of the wire harness is lowered, and the copper is mixed into the steel constituting the panel, and the quality of the collected steel is lowered.

  The present invention aims to solve such problems. That is, an object of the present invention is to provide a wire harness that can be efficiently removed and has improved recyclability.

  In order to solve the problems and achieve the object, the invention described in claim 1 is a wire harness including a plurality of electric wires bundled with each other, and is a hollow which is bundled with the plurality of electric wires and sealed. And a coloring member that is accommodated in the outer shell and that adheres to the outer surface of the electric wire and colors the electric wire when the outer shell is ruptured. It is a wire harness characterized by.

  The invention described in claim 2 is the wire harness described in claim 1, further comprising a binding member that is wound around the plurality of electric wires and bundles the electric wires, and the binding member is arranged in the longitudinal direction of the electric wires. A wire harness that is wound around a position overlapping with a colored member.

  According to a third aspect of the present invention, in the wire harness according to the first or second aspect, a part of the outer wall forming the outer shell part is formed thinner than the other part of the outer wall. It is the wire harness characterized by this.

  According to the first aspect of the invention, when the outer shell portion is ruptured by impacting the coloring member, the coloring material accommodated in the outer shell portion adheres to the outer surface of the electric wire and colors the electric wire. For this reason, an electric wire, ie, a wire harness, can be visually recognized easily. Therefore, the removal work of the wire harness can be performed efficiently in a shorter time, and the recyclability can be improved by reducing the remaining wire harness.

  According to the second aspect of the present invention, the bundling member wound around the position overlapping the coloring member serves as a mark of the position where the coloring member is embedded. Therefore, it is possible to reliably give an impact to the colored member.

  According to the third aspect of the present invention, a part of the outer wall of the outer shell part is formed thinner than the other part of the outer wall and is easily broken. Therefore, the outer shell can be reliably ruptured with a smaller force.

It is a side surface (partial cross section) figure which shows the modification of the wire harness of this invention.

  Hereinafter, a wire harness 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. As shown in FIG. 1, a wire harness 1 according to an embodiment of the present invention is attached to a panel 2 of an automobile as a moving body and routed in the automobile.

  Panel 2 constitutes the body of an automobile. The panel 2 has a hole (not shown) through which a wiring clip (not shown) attached to the wire harness 1 is locked.

  As shown in FIG. 1, the wire harness 1 includes a plurality of electric wires 3, a coloring member 4, and a tape 5. Each electric wire 3 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. The covering portion covers the core wire. For this reason, the outer surface of the coating | coated part has comprised the outer surface 3a (FIG. 1) of the electric wire 3. FIG. The covering portion has a dark color (a color with low brightness such as black) so that the wire harness 1 is not conspicuous even if the wire harness 1 is exposed and wired in the engine room or the like. A connector (not shown) is attached to the end of each electric wire 3. In addition, in FIG. 3 thru | or FIG. 5, the some electric wire 3 is drawn collectively on one.

  As illustrated in FIG. 2A, the coloring member 4 includes an outer shell portion 41 and a coloring material 42. The outer shell portion 41 is made of a synthetic resin. The outer shape of the outer shell portion 41 is formed in a flat ellipsoid shape that is crushed in the vertical direction in FIG. 2A and extends in the horizontal direction in FIG. Further, the outer shell portion 41 has an outer wall 43 and is formed in a sealed hollow shape. The outer shell portion 41 accommodates a liquid coloring material 42 inside (sealed hollow portion).

  Further, as shown in FIG. 2A, the outer wall 43a (corresponding to a part of the outer wall 43) at both ends in the longitudinal direction of the outer shell portion 41 (left and right direction in FIG. 2A) is the outer shell portion. 41 is formed thinner than the outer wall 43b (corresponding to the other part of the outer wall 43) of the central part in the longitudinal direction of 41 (other than the both ends). The thin outer wall 43a has a thickness that does not break during normal times (except when the automobile is dismantled). Further, when the outer wall 43a gives an impact such as crushing the outer shell portion 41 with the heavy machine 6 or the like to be described later from the vertical direction in FIG. It is set as the thickness which fractures as shown in FIG. That is, the outer wall 43b is provided in a portion that receives the impact of the outer shell portion 41, and the outer wall 43a is provided in a portion that is separated from the portion that receives the impact of the outer shell portion 41. In addition, according to the position which gives the impact to the outer shell part 41, the part which provides the outer walls 43a and 43b can be changed suitably.

  The coloring material 42 is a liquid material in which a coloring material such as a dye or a pigment is dissolved and dispersed in a solvent. The coloring material 42 is a coloring liquid or a paint. The colored liquid indicates that the dye is dissolved in the solvent, and the paint indicates that the pigment is dispersed in the dispersion. As described above, the coloring material 42 is scattered outside the outer shell portion 41 as shown in FIG. 2B by breaking the outer wall 43a and rupturing the outer shell portion 41, so that the outer surface 3a of the electric wire 3 is broken. The wire 3 is colored by adhering to.

  In this specification, “coloring the electric wire” means “strong coloring” in which the coloring material 42 adheres firmly to the outer surface 3a and is retained for a long time, and the coloring material 42 adheres to the outer surface 3a with a weak adhesion. Or “weak coloration” that adheres temporarily (only for a short time). “Weak coloring” means, for example, coloring that the coloring material 42 is easily peeled off when the colored portion of the electric wire 3 is rubbed, or coloring that the coloring material 42 is held between the electric wires 3 by surface tension. It is. Even such “weak coloration” is sufficiently effective in the present invention.

  Such a coloring material 42 has a color (indicated by rough dots in FIG. 5) different from the color of the covering portion of the electric wire 3 (indicated by white in FIG. 5). Furthermore, since the covering portion is dark in color, it is desirable that the colorant 42 has a lighter color than the covering portion such as white, yellow, or fluorescent color. In this case, since the colored portion of the electric wire 3 stands out from the surroundings (and the uncolored portion of the electric wire 3), it becomes easier to visually recognize the wire harness 1.

  As shown in FIG. 1, the coloring member 4 having the above-described configuration is arranged between the plurality of electric wires 3 so that the longitudinal direction of the outer shell portion 41 is parallel to the longitudinal direction of the electric wires 3. 41 is bundled with these electric wires 3 in the state which contacted the outer surface 3a of the electric wires 3. FIG. When the automobile is disassembled, the heavy machine 6 is caused to collide with a portion where the coloring member 4 of the electric wire 3 is embedded, and the outer shell portion 41 is ruptured by giving an impact to the coloring member 4. Then, the coloring material 42 scatters outside the outer shell portion 41 and adheres to the outer surface 3a of the electric wire 3 surrounding the outer shell portion 41, thereby coloring the electric wire 3 in a color different from that of the covering portion.

  For this reason, it is desirable that the colored member 4 is arranged in a portion where the heavy machine 6 is likely to collide in the wire harness 1 arranged in the automobile. For example, when the coloring member 4 is disposed in a portion of the wire harness 1 that is exposed and routed in the engine room or the like, the coloring device is caused to collide the heavy machinery 6 with the wire harness 1 without cutting the panel 2. 4 can be impacted. Further, when the coloring member 4 is arranged on the side away from the panel 2 of the wire harness 1 (the front side in FIG. 1), the coloring member 4 approaches the heavy machine 6, so that the coloring member 4 is given a large impact. be able to.

  The tape 5 is a well-known harness tape. The tape 5 is wound around the outer surfaces 3 a of the plurality of electric wires 3 and bundles these electric wires 3. As shown in FIG. 3, the tape 5 is wound in a ring shape, and is wound around a plurality of locations arranged at intervals from each other along the longitudinal direction L of the electric wire 3 (indicated by an arrow L in FIG. 3 and the like). Yes. The tape 5 may be a binding band or the like.

  Moreover, tape 5a (shown in FIG.1 and FIG.3. It corresponds to a binding member) among the tapes 5 wound around a plurality of places is wound around the portion where the coloring member 4 of the plurality of electric wires 3 is embedded. Is wound around a position overlapping the coloring member 4 in the longitudinal direction L. Further, the tape 5a is wound around a central portion in the longitudinal direction of the outer shell portion 41 of the coloring member 4, that is, a position overlapping the outer wall 43b. For this reason, the tape 5a is a mark of the position where the coloring member 4 is embedded. The tapes 5 other than the tape 5a are darkened (indicated by white in FIG. 3 and the like) in the same manner as the covering portion of the electric wire 3 so as not to stand out. The tape 5a has a color different from that of the covering portion (indicated by fine dots in FIG. 3 and the like), and more preferably has a higher brightness than the covering portion.

  In the wire harness 1 having the above-described configuration, after a wiring clip or the like is attached in place, the wiring clip is engaged with a hole in the panel 2 and attached to the panel 2 and routed in the automobile. In the wire harness 1, a connector attached to the electric wire 3 is connected to a connector of an electronic device mounted on an automobile, and transmits electric power and various signals to the electronic device. In this way, the wire harness 1 routed in the automobile is not noticeable even if it is routed at a position visually recognized by an occupant such as an engine room, for example, because the covering portion of the electric wire 3 is dark. Yes.

  The wire harness 1 routed in the automobile is peeled off from the panel 2 by using a heavy machine 6 such as a nibler (FIG. 3), for example, in a covered factory when the automobile is disassembled. Since the factory can accommodate heavy machinery 6, the ceiling is high and the interior is relatively dark.

  As shown in FIG. 3 and the like, a clamping unit 61 is attached to the tip of the arm 60 of the heavy machine 6. The clamping unit 61 includes a fixed tooth 61a attached to the arm 60 so as to be rotatable about the axial direction of the arm 60, a movable tooth 61b attached to the fixed tooth 61a so as to be able to contact with and separate from the fixed tooth 61a, It has. The clamping part 61 clamps the wire harness 1 between the fixed tooth 61a and the movable tooth 61b.

  When the wire harness 1 described above is removed from the panel 2, first, the heavy machinery 6 used for car dismantling work and the car to be dismantled are brought into the factory, and the heavy machinery 6 is operated as shown in FIG. Then, the clamping unit 61 is brought closer to the automobile. Then, using the tape 5a as a mark, the tip of the sandwiching portion 61 is caused to collide with a portion of the electric wire 3 around which the tape 5a is wound.

  Then, in the coloring member 4 arranged on the inner side of the tape 5a, the outer wall 43b is crushed by receiving an impact, and the outer wall 43a is broken. Then, as shown in FIG. 4, the coloring material 42 scatters outside the outer shell portion 41. The coloring material 42 adheres to the outer surface 3a of the surrounding electric wire 3, and first colors both side portions of the tape 5a of the electric wire 3 in a color different from the covering portion. Further, the coloring material 42 propagates along the outer surface 3a of the electric wire 3 and between the electric wires 3 by a capillary phenomenon, and spreads around the portion where the coloring member 4 of the electric wire 3 is embedded. Coloring.

  Since the wire harness 1 in which the electric wires 3 are colored in this way stands out from the periphery, the operator can easily see from the driver's seat of the heavy machinery 6. Thereafter, the heavy machinery 6 is operated, and the colored portion of the electric wire 3 is sandwiched between the clamping portions 61 and peeled off from the panel 2 as shown in FIG. Thus, the wire harness 1 is removed from the panel 2.

  According to the present embodiment, when the outer shell 41 is ruptured by colliding the coloring member 4 with the clamping portion 61 of the heavy machine 6, the coloring material 42 accommodated in the outer shell 41 is applied to the outer surface 3 a of the electric wire 3. It adheres and colors the electric wire 3. For this reason, an operator can easily visually recognize the electric wire 3, that is, the wire harness 1. 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.

  Further, the tape 5 a wound around the position overlapping the coloring member 4 serves as a mark of the position where the coloring member 4 is embedded. Therefore, an impact can be applied to the colored member 4 with certainty.

  Further, the outer wall 43a of the outer shell portion 41 is formed thinner than the outer wall 43b and is easily broken. Therefore, the outer shell portion 41 can be reliably ruptured with a smaller force. Moreover, the thin outer wall 43a is provided in the part distant from the part which receives the impact of the outer shell part 41, and is distribute | arranged to the position away from the tape 5a rather than the outer wall 43b. Therefore, it is possible to make the portion of the electric wire 3 away from the tape 5a, which is difficult to visually recognize, to stand out, and the wire harness 1 can be easily visually recognized over a wider range.

  In the above-described embodiment, the coloring member 4 is embedded between the plurality of electric wires 3. However, in the present invention, the coloring member 4 may be stacked on the outer surface 3a of the plurality of electric wires 3 in a bundled state, and the tape 5a may be wound around the electric wires 3 and the coloring member 4 to bundle them.

  In the embodiment described above, the outer shape of the coloring member 4 is formed in a flat ellipsoidal shape, but the outer shape of the coloring member 4 may be any shape. In addition, the coloring member 4 may be embedded in a plurality of portions wound around the tape 5a, or may be embedded in a plurality of locations arranged at intervals from each other along the longitudinal direction L of the electric wire 3. The tape 5a may be wound around each location.

  In the above-described embodiment, the tape 5a is a mark of the position where the coloring member 4 is embedded. However, the tape 5a is not necessarily provided. In this case, the colored member 4 may be disposed in the vicinity of the cut portion 21 (FIG. 6) of the panel 2 when the automobile is disassembled. By doing so, when the panel 2 is cut by the heavy machine 6 as shown in FIG. 6, the panel cutting part 62 impacts the colored member 4 and ruptures the outer shell part 41 without the operator being aware of it. Can do.

  The above-described embodiments are merely representative examples of the present invention, and the present invention is not limited to the above-described embodiments. That is, various modifications can be made without departing from the scope of the present invention.
