Description

The present invention relates to a routing structure of a wire harness spanned between the side door and the car body.

  Opening and closing members that can be freely opened and closed via hinges and body bodies such as doors such as side doors and back doors of automobiles, trunk lids, and the like. A wire harness is routed to the opening / closing member.

Conventionally, as shown in FIG. 9, a wire harness routed between a vehicle body and a side door is connected to the body 3 side through a through hole 1 b drilled in a vehicle body side end surface of the inner panel 1 a of the door 1. (Door harness) W / H is bridged. The wire harness W / H has the through hole 1b provided outside the weather strip 2 and is routed above the hinge H between the vehicle body and the door. Only twisting occurs, and the wire harness does not expand or contract.
However, since it is very difficult to penetrate the wire harness W / H through the through hole 1b, many proposals for wiring the wire harness to the body side without penetration have been made.

  When wiring the wire harness to the body side, if it is routed from the interior side of the inner panel to the body side, the wiring work can be facilitated because it does not pass through the through hole. Since the position is displaced to the indoor side from the hinge coupling position of the body and the door, it is necessary to expand and contract the wire harness when the door is opened and closed.

In order to solve this problem, the present applicant has previously provided Patent Document 1 (Japanese Patent Laid-Open No. 10-934). In this wire harness routing structure, as shown in FIG. 10, a substantially triangular space 1c is provided on the interior side surface of the inner panel 1a of the door 1, while the wire harness W / H has an extra length that can follow the opening and closing of the door. A portion is provided, and the extra length portion is accommodated in the space 1c and pulled out from the outlet of the space 1c to the body side.
With the above configuration, when the door is opened, the wire harness is pulled out of the space 1c. When the door is closed, the extra length of the wire harness is accommodated in the space 1c, and the wire harness is interlocked with the opening / closing operation of the door. Can be followed.

  However, in the case of the above-described configuration, since the wire harness only has the electric wire group converged and wound with tape, the rigidity is weak, so that there is a possibility that the wire harness cannot be reliably pulled into the space 1c when the door is closed. At that time, the wire harness hangs down due to gravity between the body side and the door side, and in some cases, the wire harness may be caught between the door and the body.

  In another patent document 2 (Japanese Patent Laid-Open No. 10-16672), as shown in FIG. 11, the wire harness is protected by a protector 5, and one end of the wire harness is slidable on a slide guide 8 provided on the inner panel side of the door. It is mated. The door side of the protector 5 is attached to the body 3 by a swingable connector 9.

  Although the above-mentioned problem of Patent Document 1 is partially solved in Patent Document 2, another problem arises. That is, the protector 5 and the slide guide 8 need not only slide in the expansion / contraction direction with each other, but also need to have enough play to absorb the movement in the rotation direction as the door rotates. The problem arises that resonance and abnormal noise occur. On the other hand, if the play is stuffed, it becomes difficult to slide, causing a problem of catching.

In addition, there is a problem in durability due to the fact that the wire harness is bent or stretched at an acute angle inside the door, and repeated stress is concentrated on a part. In particular, since the wire harness is fixed to the door side with a clamp or the like at the portion 1d in FIGS. 10 and 11, bending stress is concentrated on this portion of the wire harness, and the wire harness may be damaged due to fatigue. there were. At the same time, the wire harness is forcibly bent, an excessive force is applied between the protector 5 and the slide guide 8, and the smooth slide is obstructed, causing abnormal noise.
Japanese Patent Laid-Open No. 10-934 Japanese Patent Laid-Open No. 10-16672

The present invention has been made in view of the above problems, in the case of wiring harness to wired to the side door or et vehicle body in the through-less, the wire harness can reliably follow the opening and closing operation of the side door It is an object of the present invention to prevent the wire harness from being repeatedly bent largely and repeatedly from following the opening and closing operation of the side door , and to prevent the wire harness from being damaged or generating abnormal noise.

In order to solve the above-mentioned problems, the present invention provides a wiring structure for a wire harness in which a wire harness is stretched between a body of an automobile and a side door hinged to the body so as to be stretchable and rotatable. ,

Also, the grommet that is fixed to the tip of the rigid tube is not allowed to penetrate the protector's entrance / exit opening, and the grommet is stopped at the opening position of the guide portion when the extra length of the wire harness is drawn into the extra length absorption space. Thereby, the drawing-in amount of the wire harness can be regulated. Also, in order to absorb the movement of the side door in the rotational direction, a gap must be provided between the hard tube and the side door , but the grommet is brought into contact with and pressed against the protector , so that the hard tube together with the grommet. Is fixed, and it is possible to prevent the hard tube from resonating with the body vibration and generating abnormal noise.

As described above, in the present invention you arranging a door harness routed in a side door to the vehicle body, for arranging the door harness to the indoor side of the weather strip, the end face of the conventionally required by the inner panel The operation of inserting the provided through hole is unnecessary, and the wiring workability of the wire harness can be greatly improved.

The above is the basic configuration of the present invention. In addition, the following configuration is preferable in the present invention.
The tip of the hard tube and the grommet are fixed by fitting a ring on the tip of the hard tube or by projecting a flange, and inserting the tip of the hard tube into the grommet. It is preferable to fix by pushing the ring or flange into the groove.
In addition, the other end of the hard tube and the wire harness are preferably fixed by projecting a tape-wrapped tongue piece on the other end of the hard tube and fixing the tongue piece, the wire harness, and the tape.
However, the fixing of the hard tube, the grommet, and the wire harness is not limited to the above configuration, and other appropriate means may be adopted.

The grommet is connected to the grommet as a diaphragm part by connecting the large-diameter cylinder part to the small-diameter cylinder part through the thin-walled connection cylinder part, and the thin-walled connection cylinder part is inserted into the large-diameter cylinder part in a folded state It is preferable that when the side door is opened, the thin-walled connecting cylinder portion is pulled out from the large diameter cylinder portion and bendable.

By providing the diaphragm portion with a thin connecting tube portion, the side door can be opened and closed in the left-right direction. Therefore, at least the left and right sides in the circumferential direction of the thin connection portion are thin, and the top and bottom sides are not necessarily thin.
In the original configuration, the diaphragm part is inserted into the large-diameter cylinder part in a folded shape so that the thin-walled connection cylinder part is folded back, so that when the wire harness is pulled when the side door is opened, the diaphragm part is exposed to the outside. By being pulled out, the grommet itself can be extended by the length of the thin connecting cylinder portion, and the following operation of the wire harness can be performed more smoothly. On the other hand, even when the side door is closed, the thin connecting tube part returns to the original folded state, and the wire harness can be smoothly followed. In addition, when the side door is closed, the space between the body and the side door is narrowed, but the grommet itself is shortened so that it can be well accommodated in the narrow gap.

In the above configuration, the protector in which the slide space for slidably housing the hard tube and the surplus length absorption space for curving and accommodating the surplus length portion of the wire harness are provided in a substantially triangular shape. A shallow protector is preferred.

  As shown in FIG. 3, the hard tube 60 is formed of a hard resin that does not easily bend, and a flange 62 is provided at one end of a cylindrical main body portion 61, and is fitted into the grommet 50. The flange 62 may be provided by integral molding, or a separate ring may be fitted and fixed instead of the flange 62. A tape-wrapped tongue piece 63 projects from the other end, and the tape T is wound around and fixed to the tape-wrapped tongue piece 63 and the wire harness 40. Although the hard tube 60 has a cylindrical shape, it can be positioned in the rotational direction by using a square tube.

The grommet 50 has the shape shown in FIG. 4, FIG. 4A is a side view seen from the door side, FIG. 4B is a cross-sectional view of a free-length original state, and FIG. FIG.
The grommet 50 is integrally formed from an elastic material such as rubber or elastomer, and has a cylindrical shape that allows the wire harness to pass therethrough.
A maximum outer cylindrical portion 51 having an oval shape is provided at one end in the axial direction, a vehicle body locking portion 52 is recessed in the outer peripheral surface, and the outer peripheral surface on the tip side of the vehicle body locking portion 52 is an inclined surface. It is easy to insert into the 20 locking holes 22.

A perfectly circular large-diameter cylindrical portion 53 is continued at an eccentric position with respect to the maximum outer cylindrical portion 51, and the large-diameter cylindrical portion 53 is continuously connected to a small-diameter cylindrical portion 55 via a thin connecting cylindrical portion 54. A pressing tube portion 56 is provided at the tip of the tube portion 55. The large-diameter cylindrical portion 53, the thin-walled cylindrical portion 54, and the small-diameter cylindrical portion 55 form a diaphragm portion 58 that can change the length in the axial direction.
The thin-walled connecting tube portion 54 is shaped in advance so as to wrap around the inside of the large-diameter tube portion 53 in a bent state, and is connected to the small-diameter tube portion 55. When the small-diameter tube portion 55 is pulled, the thin-wall connecting tube portion 54 When it is pulled out and the tensile force applied to the small-diameter cylindrical portion 55 is released, it returns to its original shape and wraps around the large-diameter cylindrical portion 53.
That is, the grommet 50 can be expanded and contracted by a certain dimension in the axial direction by the diaphragm portion 58. When the door is closed, the grommet 50 is shortened to fit in the narrow gap between the door 10 and the body 20, and when the door 10 is opened, FIG. As shown in FIG. 5, the wire harness 40 extends in accordance with the tensile force and can absorb the movement in the bending direction.

  A hard tube locking groove 57 is bulged inside the pressing tube portion 56, and a flange 62 of the hard tube 60 is fitted into the hard tube locking groove 57. The pressing cylinder portion 56 has an outer diameter that cannot be passed through the through hole 77a of the protector 70, and is pressed and contracted by contacting the closing wall 77 on the periphery of the through hole 77a when the door is closed. For this reason, even if there is play between the hard tube 60 and the opening / closing opening 71 of the protector 70, resonance is caused by body vibration or the like so that no abnormal noise is generated.

  The wire harness 40 is passed through the hard tube 60 and fixed with the tape T, and then passed through the grommet 50, and the distal end of the hard tube 60 is fitted and fixed to the pressing cylinder portion 56. In this state, the hard tube 60 is slidably accommodated in the slide space 79 of the protector 70. A required dimension of the wire harness 40 extending from the portion fixed by the hard tube 60 and the tape T is defined as a surplus length portion 40a. As shown in FIG. 6, the end portion of the long portion 40 a is locked by a band-type clamp 82 at the position of the drawer opening 76 of the protector 70.

The clamp 82 is made of a resin molded product having elasticity, and includes a band locking portion 82b at the base end portion of the band 82a. The band 82a is wound around the wire harness 40 and locked by the band locking portion 82b. A locking shaft portion 82c protrudes from the band locking portion 82b, a locking blade portion 82d is provided in a folded shape from the tip of the locking shaft portion 82c, and is locked to the tip of the locking blade portion 82d. The shape is provided with a stepped portion 82e.
The locking hole 78 formed in the protector 70 is locked with a gap C in which the locking step portion 82e of the locking blade portion 82d can rotate.

With this structure, the locking hole 78 provided in the protector is round, so that the clamp 82 can be rotated around the locking shaft portion 82c, and the wire harness 40 attached to the clamp 82 is provided. Can also be rotated. Such clamps 82 can integrally molded with resin, after bundling the wire harness 40 on the band 82a, the engaging hole 78, it is possible to lock only by inserting the locking blade portion 82d, Ru improve workability be able to.
Thus, the wire harness 40 is rotatably locked to the side door side via the clamp 82 at the position of the drawer opening 76 of the protector 70, so that the wire harness 40 is bent in the vicinity of the clamp 82. Can ease concentration. Further, since the clamp 82 is rotatable, the excessive bending of the wire harness 40 is alleviated, so that an excessive twisting force can be prevented from being applied to the hard tube 60. As a result, the rigid tube 60 can be smoothly slid, followed by rapid opening and closing of the door, and the occurrence of damage and abnormal noise can be prevented.

Further, a protective material 41 is wound and fixed on the extra length 40a of the hard tube 60 with a tape T as shown in FIG. The protective material 41 is a resin molded product having smoothness, and has a shape in which a stepped convex portion 42 is provided at the center of a rectangular substrate 43a and ribs 44 are provided at both ends.
The protective material 41 slidably abuts the stepped protrusion 42 on the inner surface of the upper peripheral wall 75a of the protector 70 so that the wire harness 40 does not directly contact the inner surface of the protector and protects the wire harness 40 from wear. The movement of the wire harness 40 can be performed smoothly.

Next, the operation of the wire harness 40 that accompanies the opening and closing of the door in the wiring harness wiring structure having the above-described configuration will be described.
When the door 10 shown in FIG. 2 is closed and the door 10 shown in FIG. 1 is opened, the thin connecting tube portion 54 of the grommet 50 is bent along with the rotation of the door 10 so that the door 10 is routed. The bent wire harness 40 is followed.
Moreover, since the rotation fulcrum of the door 10 and the wiring position of the wire harness 40 are shifted when the door 10 is opened, the wire harness 40 needs to be extended to follow. As shown in FIG. 2 with the door closed, the surplus length portion 40a of the wire harness 40 is accommodated in the surplus length accommodating space 72 so as to be curved along the corner side. From this state, following the opening operation of the door 10, the hard tube 60 moves to the left in the figure in the slide space 79, and the hard tube 60 moves to the body 20 side through the through-hole 77 a and the entrance / exit opening 71. In accordance with this, the surplus length portion 40a in the surplus length absorption space 72 is brought close to the side peripheral wall 75b and is pulled out from the curved state to the slanted state, as shown in FIG. It becomes.

When the door 10 is closed from the door open state shown in FIG. 1, the opening operation is reversed and the wire harness 40 is pushed into the protector 70 together with the hard tube 60, and the extra length 40 a of the wire harness 40 is extra. It is drawn in and accommodated in the long portion absorption space 72 so as to bend along the corner portion.
The hard tube 60 is pulled into the protector 70, and the grommet 50 is also moved to the protector 70 side in conjunction with the hard tube 60, and stops at a position where the pressing cylinder portion 56 of the grommet 50 contacts the closing wall 77. In this state, the door 10 is completely closed.

As described above, when the door 10 is opened and closed, the wire harness 40 that enters and exits the through hole 77a of the protector 70 is protected by the hard tube 60, so that it does not slidably contact the inner surface of the through hole 77a. Go in and out with 60 smoothly. And compared with the case where only a wire harness is used, the wire harness is not loosened between the door 10 and the body 20 and is stretched while maintaining a straight state, and is sandwiched between the door 10 and the body 20. Absent.
Further, since the grommet 50 fixed to the tip of the hard tube 60 is not allowed to pass through the through hole 77a of the protector 70, the grommet 50 is stopped at the position of the through hole 77a of the protector 50 when the door is closed, and the amount of wire harness 40 drawn in is regulated. it can. In order to absorb the movement of the door 10 in the rotational direction, a space is provided between the hard tube 60 and the through hole 77a, but the grommet 50 is brought into contact with and pressed against the closing wall 77 of the protector 70. The hard tube 60 is also fixed together with the grommet 50, and it is possible to prevent the hard tube 60 from resonating with the body vibration and generating abnormal noise.

In addition, in this invention, although the clamp which latches a wire harness to a protector is made into the said shape , it is good also as a structure shown in FIG. The clamp 82 is integrally formed of an elastic resin. Band 82a is a half, constitute the hinge the coupling portion 82h can be formed thin, the upper half of the band 82a is rotatable in the connecting portion 82h around. Reference numerals 82g and 82f denote male and female hook portions, and the hook portions 82g and 82f can be engaged with each other with the wire harness 40 sandwiched therebetween, so that the wire harness 40 can be easily assembled. 82j is a downwardly thin and dish-shaped spacer having a spring force, which absorbs manufacturing errors of the protector 70 and the clamp itself, eliminates play between the clamp and the protector, and prevents sticking in the rotational direction. Can do. Further, the spacer 82j serves as a spacer that keeps the wire harness 40 at a certain distance from the wall of the protector 70, and prevents the wire harness from directly contacting and rubbing against the protector wall.
