  Hereinafter, the wiring structure of the wire harness of the embodiment of the present invention will be described. First, an outline of an embodiment of the present invention will be described. FIG. 1 is a perspective view of a wire harness routed across a bridge, illustrating a wire harness routing structure according to an embodiment of the present invention. FIG. 2 is a side view of a wire harness routed over a cross, illustrating a wire harness routing structure according to an embodiment of the present invention. In the embodiment of the present invention, a space between the vehicle body panel 9 and the engine 5 where the wire harness is routed is referred to as “crossover”.

  The wire harness W is configured by bundling a plurality of electric wires with a tape or a vinyl tube. The wire harness W includes an input-side connector 19 and an output-side connector 22 connected to both ends. The wire harness W is located on the engine side 4, the electronic device 18 disposed around the engine 5 or the engine 5, and the vehicle body side 8. The electronic device 21 disposed around the vehicle body panel 9 is electrically connected via the input-side connector 19 and the output-side connector 22.

  In the wire harness W, one section of the electric wire has a U shape. In FIG. 1, as for the wire harness W, the electric wire of one area has drawn U shape. More specifically, the wire harness W is configured by three sections of a bottom portion Wa, a first side portion Wb, and a second side portion Wc, and the bottom portion Wa, the first side portion Wb, and the second side portion Wc are in the next positions. They are routed across to make a relationship. That is, the bottom portion Wa has one end connected to one end of the first side portion Wb and the other end connected to one end of the second side portion Wc. For this reason, the bottom portion Wa is located in a section between the first side portion Wb and the second side portion Wc. The first side Wb has one end connected to one end of the bottom Wa and the other end fixed to the engine 5. For this reason, the 1st side part Wb is located in the area of the engine side 4 rather than the bottom part Wa. Further, the first side portion Wb is bent at one end of the bottom portion Wa, and is bent at another portion so as to extend toward the electronic device 18 of the engine 5. The second side Wc has one end connected to the other end of the bottom Wa and the other end fixed to the vehicle body panel 9. For this reason, the second side portion Wc is located in a section on the vehicle body side 8 relative to the bottom portion Wa. Further, the second side portion Wc is bent at the other end of the bottom portion Wa, bent at another location, and extends toward the electronic device 21 of the vehicle body panel 9. When making one section of the wire harness W U-shaped, it is conceivable to add a U-shaped habit to the electric wire.

  The wire harness W is fixed to the engine 5 at the first side Wb and to the vehicle body panel 9 at the second side Wc. In order to fix the first side Wb to the engine 5, the engine 5 is provided with a mounting bracket having a mounting hole 51, and is provided on a band T that binds the first side Wb to the mounting hole 51. The first side Wb is fixed to the engine 5 by inserting the anchor protrusion of the clip. That is, the anchor protrusion has a blade portion that elastically changes in a direction intersecting the direction in which the anchor protrusion is inserted, and a base on which the blade portion protrudes, and the anchor protrusion is inserted into the mounting hole 51. At this time, the blade portion penetrating the mounting hole 51 is elastically changed to have a width larger than the diameter of the mounting hole 51, and the elastically changed blade portion and the base sandwich the peripheral portion of the mounting hole 51 in the mounting bracket. Similarly, in order to fix the second side portion Wc to the vehicle body panel 9, a pair of band holes 91 are formed in the vehicle body panel 9, and the second band T is inserted through the pair of band holes 91. The second side portion Wc is fixed to the vehicle body panel 9 by binding the side portion Wc. The wire harness W is routed to a cross located between the engine 5 and the vehicle body panel 9 with connection to the electronic devices 18 and 21 and fixing to the mounting hole 51 and the pair of band holes 91 by the band T. ing. In the wire harness W, a section from a portion fixed to the engine 5 by the mounting hole 51 by the band T to a portion fixed to the vehicle body panel 9 by the pair of band holes 91 by the band T is referred to as a crossover portion. There is. The first side Wb is fixed to the engine 5 and the second side Wc is fixed to the vehicle body panel 9. The fixing structure using the band T, the mounting hole 51, and the band hole 91 is not limited. Various methods for fixing the wire harness to the member to be routed, such as a method using a band and a clamp, can be applied.

  In the wiring structure of the wire harness of the present invention, the wire harness W routed over the cross has a U-shaped wire in one section. When the wire harness W is routed as described above, the engine vibration propagates to the first side Wb of the wire harness W when the engine is driven. However, the amplitude of the vibration is attenuated by one section of the wire harness W having a U shape. The one section of the wire harness W plays a role of a cushioning material. As a result, the vibration that reaches the output-side connector 22 via the wire harness W is attenuated by the crossing portion of the wire harness W, so that the output-side connector 22 is damaged and the output-side connector 22 is near. Wire breakage can be prevented.

  In the wire harness wiring structure of the present invention, a part of the wire harness W is fixed to the vehicle body panel 9. By the way, the frequency at which the engine side 4 vibrates is different from the frequency at which the vehicle body side 8 vibrates, and the amplitude of each vibration is also different. The vibration having one large amplitude is propagated to the other, which causes a situation such as breakage or disconnection of the electric wire, release of the connector fitting state, or poor contact of the terminals. In general, the vibration amplitude of the engine 5 tends to be larger than the vibration amplitude of the vehicle body panel 9, and therefore, it is required to prevent the vibration from propagating to the vehicle body panel 9. As described above, by fixing the second side portion Wc, which is a part of the wire harness W, to the vehicle body panel 9 having a small amplitude, vibration propagating through the transition portion of the wire harness W is also attenuated at the fixing portion.

  In embodiment mentioned above, the vibration which propagates the transition part of the wire harness W can be damped because the electric wire of the one section of the wire harness W wired by the transition has comprised U shape. Furthermore, even a slight vibration propagated through a section of the wire harness W can be attenuated by fixing a part of the wire harness W to the vehicle body panel 9 having a small amplitude.

  The outline of the present embodiment has been described above, but the specific configuration is not limited to this form, and any design change or the like within a range not departing from the gist of the present invention is included in the present invention. .

  In this embodiment, the wire harness W demonstrated that the some electric wire was bundled with tape winding, a vinyl tube, etc. However, if the electric wire is exposed in at least one part of the bottom part Wa, a part of the first side part Wb, and a part of the second side part Wc, and the electric wire is separated, the connecting part of the wire harness W The propagating vibration can be further damped at that point.

  Subsequently, the wiring structure of the wire harness according to the embodiment of the present invention will be described in more detail. Here, when routing the wire harness in which the electric wire in one section forms a U-shape, the routing structure that accommodates the U-shaped section in the protector and routes the protector in that state Will be described.

  Next, a series of work procedures for routing the wire harness W using the protector 100 described above will be described.

  First, the wire harness W is accommodated in the first protector 200. That is, the first cylindrical portion C1 that covers the first side portion Wb of the wire harness W is disposed in the first insertion hole 220 so that the protrusion 221 is engaged with the concave portion of the outer wall. Further, the wire harness W is arranged in the first protector main body 210 so that the bottom portion Wa, the first side portion Wb, and the second side portion Wc draw a U shape in the first protector main body 210. And the 2nd side part Wc is arrange | positioned in the 2nd penetration hole 230, and the position of the 2nd cylinder part C2 is adjusted so that the 2nd side part Wc may be exposed from a corrugated tube to the vicinity of the clamp hole 261. Thereafter, a band 270 with a clamp is wound around a part of the second side portion Wc facing the clamp hole 261, and the clamp 271 is fitted into the clamp hole 261. The second protector body 310 is assembled to the first protector body 210 in this state. This assembled state is shown in FIG.

  If necessary, the front end of the band enters the protector 100 from one of the band insertion hole 251 of the first protector main body 210 and the band insertion hole 351 of the second protector main body 310, and a part of the exposed wire The band is rotated so that the tip of the band is taken out from the other of the band insertion hole 251 of the first protector body 210 and the band insertion hole 351 of the second protector body 310 toward the outside of the protector 100. Then, the band support wall 252 of the first protector main body 210 and the band support wall 352 of the second protector main body 310 are bound so as to be assembled. Through this series of operations, the second side portion Wc can be firmly fixed by the first protector body 210 and the second protector body 310.

  When the protector 100 assembled in this way is arranged on the cross between the engine 5 and the vehicle body panel 9, the bracket 370 is fixed to a bracket fixing base 910 formed on the vehicle body panel 9 facing the cross.

  In this embodiment, the wire harness W routed over the bridge is protected by the protector 100 while the electric wire in one section forms a U shape. Although the wire harness W is covered with the corrugated tube, it is considered that the wire harness W vibrates inside the corrugated tube, but the first side portion Wb of the wire harness W is formed by one section of the U-shaped wire harness W. The vibration propagating from the bottom to the bottom Wa attenuates the amplitude. The one section of the wire harness W plays a role of a cushioning material. As a result, since the vibration reaching the output side connector 22 is attenuated, it is possible to prevent damage to the output side connector 22 and disconnection of the electric wire in the vicinity of the output side connector 22.

  Moreover, in this embodiment, since the U shape in the one section of the wire harness W is maintained by the protector 100, it is not necessary to attach the U-shaped habit to the wire harness W.

  In the present embodiment, the second side portion Wc of the wire harness W is fixed to the protector 100 via the band 270 with clamp and the clamp hole 261. In the protector 100, a bracket 370 is fixed to a bracket fixing base 910 provided on the vehicle body panel 9. By the way, the frequency at which the engine side 4 vibrates is different from the frequency at which the vehicle body side 8 vibrates, and the amplitude of each vibration is also different. The vibration having one large amplitude is propagated to the other, which causes a situation such as breakage or disconnection of the electric wire, release of the connector fitting state, or poor contact of the terminals. In general, the vibration amplitude of the engine 5 tends to be larger than the vibration amplitude of the vehicle body panel 9, and therefore, it is required to prevent the vibration from propagating to the vehicle body panel 9. By fixing the bracket 370 of the protector 100 to the bracket fixing base 910 of the vehicle body panel 9 having a small amplitude as in the present embodiment, the second side Wc of the wire harness W is connected to the vehicle body via the band 270 with a clamp and the protector 100. Since it is fixed to the panel 9, the vibration propagating through the transition portion of the wire harness W is also attenuated at the place where it is bound by the band 270 with a clamp. In this embodiment, the vibration which propagates through the transition part of the wire harness W can be attenuated because the electric wire of the one section of the wire harness W routed in the transition is U-shaped. Furthermore, even a slight vibration propagated through a section of the wire harness W is caused by a part of the wire harness W being indirectly fixed to the vehicle body panel 9 side with a small amplitude via the band 270 with a clamp and the protector 100. Can be attenuated. In particular, if the second side portion Wc of the section of the wire harness W is fixed to the vehicle body panel 9 side, vibrations sufficiently damped in the section of the U shape can be further damped. Can do.

  Although the present embodiment has been specifically described in detail above, the specific configuration is not limited to this embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included in the present invention. Is. For example, if at least one part of the bottom portion Wa, a part of the first side part Wb, and a part of the second side part Wc is in a state where the electric wire is exposed and the electric wire is separated, the transition part of the wire harness W is The propagating vibration can be damped at that point. At this time, since the protector 100 protects the electric wires even if they are scattered, there is no possibility of disconnection at the portion exposed from the corrugated tube.

  In the present embodiment, the first cylindrical portion C <b> 1 is fixed to the protector 100 by the first insertion holes 220 and 320, and the protector 100 is fixed to the vehicle body panel 9. By fixing the first cylinder part C1 to the vehicle body panel 9 via the protector 100, vibrations propagating from the engine side 4 to the first cylinder part C1 can be attenuated. At this time, the first side portion Wb of the wire harness W is vibrated from the engine side 4 and vibrates inside the first cylindrical portion C1. When the first side portion Wb vibrates inside the first cylindrical portion C1 where the vibration is attenuated, the first side portion Wb propagates through the first side portion Wb when the first side portion Wb comes into contact with the inner surface of the first cylindrical portion C1. The vibration to be attenuated to the extent of the vibration of the first cylinder C1. As described above, the vibration that propagates through the first side portion Wb of the wire harness W can also be attenuated by fixing the first cylindrical portion C1 to the protector 100.

As described above, according to the wiring structure of the wire harness of the embodiment of the present invention in which the wire harness is routed using the protector, the vibration propagating from the engine side 4 to the wire harness W is attenuated at the following points. Yes. That is,
(1) By fixing the first cylindrical portion C1 to the vehicle body panel 5 via the protector 100, vibration propagating through the first side portion Wb of the wire harness W can be attenuated.
(2) The vibration propagated from the first side Wb of the wire harness W toward the bottom Wa and the second side Wc can be attenuated by one section of the U-shaped wire harness W.
(3) By fixing the second side portion Wc of the wire harness W to the vehicle body panel 5 via the protector 100, vibration propagating through the second side portion Wc of the wire harness W can be attenuated.
