Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness routing structure that spans between a door such as a side door of an automobile and a vehicle body, and in particular, eliminates the need for waterproofing by bridging a wire harness closer to a passenger compartment side than a weather strip. It is.

  Side doors and back doors of automobiles are attached to the vehicle body through hinges so that they can be opened and closed, and a door-side wire harness connected to electrical components attached to these doors is routed to the vehicle body side through the hinges. The connector connected to the tip of the harness is fitted and connected to the connector connected to the wire harness on the vehicle body side.

Conventionally, the wire harness routed between the vehicle body and the side door is, as shown in FIG. 10, the wire harness on the body 3 side through the through hole 1 b formed in the 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 have been made to route the wire harness to the body side without penetration.

  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 indoors from the hinge coupling position of the body and the door, it is necessary to expand and contract while twisting 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. 11, 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 a surplus 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 from 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 door opening / closing operation. Can be followed.

  However, in the case of the above-described configuration, the wire harness only has the electric wire group converged and wound with tape, so that the rigidity is weak, and 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 vehicle body side and the door side, and in some cases, the wire harness may be caught between the door and the vehicle body.

  In other patent document 2 (Japanese Patent Laid-Open No. 10-16672), as shown in FIG. 12, the wire harness is protected by a protector 5 and one end thereof can be slid to 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, the wire harness is bent or stretched at an acute angle inside the door, causing problems due to durability due to repeated stress concentration on a part, and the wire harness is not restrained inside the door. Since the swinging is repeated, there is a problem that the inner panel rubs and wears, or the body vibration resonates and generates 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. When a wire harness routed from the door to the vehicle body is routed without passing through, the wire harness can reliably follow the opening and closing operation of the door, and the opening and closing of the door It is an object to prevent damage to the wire harness that expands and contracts following the operation.

In order to solve the above-mentioned problem, the present invention is a wiring structure of a wire harness in which a wire harness is stretched and rotated between a vehicle body and a door hinged to the vehicle body,
A vehicle body locking portion projects from the outer surface of the connector connected to the distal end portion of the wire harness that is routed to the door and pulled out to the vehicle body side, and the connector and the wire harness are made of a hard resin tube. A connector locking part is provided at the distal end of the tube, and the connector is held at a position protruding from the tube distal end opening. Further, the vehicle body is held between the tube and the vehicle body locking part of the connector. A locking collar is provided at a position where it can be formed, and a required section from the position continuous to the locking collar to the door side is a bellows cylinder,
The connector protruded from the tip of the tube is inserted into a through hole formed in the vehicle body and locked to the vehicle body by the vehicle body locking portion. Provided is a wiring harness wiring structure characterized by being configured to be fitted and connected.

As described above, in the present invention, the protective material of the wire harness that spans between the door and the vehicle body is made only of a hard resin tube instead of a rubber tube to increase the protective strength of the wire harness, and when the door is closed, The wire harness that has passed through the tube between the vehicle body does not hang down. The structure of the protective material is simplified by locking the tube itself to the vehicle body panel without using the rubber or elastomer grommets conventionally used on the vehicle body locking portion side.
In particular, the connector connected to the distal end of the wire harness is fixed to the tube in a state of protruding from the opening of the distal end of the tube, and the distal end side of the tube is fixed to the vehicle body panel. Can be fixed. Therefore, when connecting the wire harness on the door side and the connector on the door side, it is only necessary to fit the connector at the tip of the vehicle side wire harness to the connector on the door side wire harness. There is no need to lock and hold the joint portion on the vehicle body side via a clip.

  A locking hook portion for the vehicle body provided on the tube and the connector locking portion may be formed separately or may be used together. In the case of dual use, it is preferable that the locking hook portion has a U-shaped cross section, and an annular protrusion is formed on the outer peripheral surface of the connector so as to be fitted in the locking hook portion.

  The diameters of the concave and convex portions of the bellows tube portion provided in the tube are the same in the length direction, and are continuously connected to the straight tube portion, or the diameters of the concave and convex portions are gradually reduced from the annular projection side to the door side. And is connected to the straight pipe part. In this way, the diameter of the bellows tube portion may be changed without being constant.

The tube has an elliptical cross section, an oval shape, or a rectangular shape with rounded corners, and has a shape corresponding to the outer shape of the connector to be inserted, and the door side continuous with the bellows tube portion is a straight tube It is said.
When a wire harness having a connector connected to the tip of the wire harness is inserted through the tube, the tube can be easily inserted if the tube shape is made to correspond to the rectangular connector. Moreover, when the wire harness routed to the door side and bridged to the vehicle body side is a flat harness, the flat harness can be inserted more easily than the tube having a circular cross section.
Further, since the door side is a straight pipe, it can be moved linearly during movement associated with the door opening / closing operation inside the door, and the wire harness following operation for the door opening / closing operation can be ensured. .
Furthermore, it is preferable that a tape winding tongue protrudes from the end of the tube on the door side, and the wire harness is fixed with tape.

It is preferable that the tube has a shape having a slit along the axial direction, and the slit is opened to allow the wire harness and the connector to be inserted from the side perpendicular to the axial direction of the tube.
Alternatively, the tube may be divided into two parts along the axial direction, and the wire harness and the connector may be inserted into one divided tube and then covered with the other divided tube to lock the two tubes together.

  When passing a wire harness having a connector connected to the tip through the tube, the wire harness cannot be passed while being expanded with a diameter-enlarging jig like a rubber tube because the tube is hard. Therefore, if the tube has a cylindrical shape with a closed cross section, it is necessary to make the tube larger than the outer shape of the connector, and even if the tube is enlarged, the work of penetrating into the long tube takes time. Therefore, it is possible to adopt a method in which only the wire group of the wire harness is passed through the tube, the wire group is drawn from the opening at the tip of the tube, and the terminal of the wire terminal is inserted and locked to the connector. When a slit is provided in the tube or a split body, the wire harness connected to the connector from the side perpendicular to the axis of the tube can be inserted into the tube, and the wire harness can be easily threaded. it can.

  In the wire harness routing structure of the present invention, the hard tube can be slidably accommodated in a guide portion provided on the door side, and the wire harness drawn from the tube can follow the opening and closing operation of the door. The surplus length portion is provided, and the surplus length portion is accommodated in the surplus length absorption space provided in the guide portion, and the wire harness is locked to the door side at the exit position of the surplus length absorption space. It is preferable that a holding portion that slidably penetrates the tube while maintaining linearity is integrally provided from the door member on the inlet side of the guide portion.

  In particular, in the wiring structure of the wire harness of the present invention, the door is a side door, the guide portion is provided on the inner side surface of the inner panel of the side door, and the hard tube pulled out from the guide portion is made more than the weather strip. It is preferable that the wire harness is bridged to the body side through the indoor side.

With the configuration of the present invention, at the time of opening the door, the wire harness extends while the extra length of the wire harness drawn into the extra length absorption space of the guide portion on the door side is pulled out. During the closing operation, the surplus length portion is drawn into the surplus length absorbing space, so that the wire harness expands and contracts to follow the door opening / closing operation. In addition, the twist of the wire harness during the opening / closing operation can be absorbed by bending and twisting the bellows tube portion by providing the tube with the bellows tube portion.
At the time of following operation of the wire harness at the time of opening and closing, since the wire harness is passed through the tube and fixed to the hard tube, the tube integrated with the wire harness moves linearly, and the extra length of the wire harness Can be reliably pulled out from the surplus length absorption space and can be reliably pulled into the surplus length absorption space, and the wire harness can be made to follow the opening and closing operation of the door. Moreover, since the wire harness is protected by the hard tube during the follow-up operation of the wire harness, it can be prevented from dripping between the vehicle body and the door or being inadvertently damaged. Furthermore, the linear movement of the tube in the guide portion can be ensured by sliding through the holding portion.

The guide portion provided on the door side has a shape in which a slide space for slidably receiving the tube and an excess length absorption space for accommodating the excess length portion of the wire harness by bending are provided continuously. The guide portion may be constituted by a substantially triangular protector made of a resin molded product, and the protector may be fixed to the inner panel of the door with a screw or the like.
Alternatively, instead of using a protector made of a separate material, a wire module is routed and a door module panel is pre-assembled with electrical components connected to the wire harness, and the door module panel has the same shape as the protector. It is good also as a guide part by providing the recessed part.

The present invention can be applied to a trunk lid or the like between the back door and the vehicle body in addition to the side door. However, as described above, the present invention is applied to a side door to which a large number of electrical components are attached, and the inner panel of the side door is applied. It is preferable that the guide portion is provided on the side surface of the interior, the tube drawn out from the guide portion is passed through the interior side of the weather strip, and the tube is bridged to the vehicle body side.
As described above, when the present invention is applied to the structure in which the door harness to be routed to the side door is routed to the vehicle body side, the door harness is routed to the indoor side rather than the weather strip. The operation of inserting the through hole provided in the end surface is not necessary, and the wiring workability of the wire harness can be greatly improved.

  As described above, according to the present invention, a hard tube is used as an exterior protective material for a wire harness routed between a door and a vehicle body, and the connector at the distal end of the wire harness passed through the tube is connected to the distal end of the tube on the vehicle body side. The connector is inserted into the through hole on the vehicle body side, and the connector at the vehicle body side wire harness is fitted to the connector. The part can be directly fixed to the vehicle body without using a clip or the like.

In addition, a wire harness that spans between the door and the vehicle body is provided at a position on the passenger compartment side away from the rotation fulcrum (hinge position) of the door so that the wire harness does not pass through the through-hole formed in the door. If it is a type, the wiring work of a wire harness can be made easy.
In addition, when the wiring structure is used, it is necessary to expand and contract while twisting the wire harness in accordance with the door opening / closing operation. However, since the wire harness is provided with a bellows tube portion on a hard tube, the wire bellows tube portion is twisted. Can be In addition, since the wire harness is inserted into and out of the door by inserting a hard tube, the extra length of the wire harness is secured in the extra length accommodation space of the guide portion on the door side without causing the wire harness to sag. And it can be stored and pulled out smoothly.

  As described above, the wiring structure of the wire harness of the present invention can enhance the protection function of the wire harness by covering the wire harness with a hard tube, and can expand and contract the wire harness when the door is opened and closed. Therefore, it is possible to provide a wiring harness wiring structure that can smoothly follow the vehicle and does not feel uncomfortable such as operability and abnormal noise.

Is housed in. In this embodiment, the axis of the tube 60 is not bent, but is arranged on the same horizontal line.

The tube 60 has the shape shown in FIG. 4, is made of a hard resin that does not easily bend, and is provided by blow molding.
The tube 60 is a substantially rectangular cylindrical portion with rounded corners at four corners, and a groove portion 60a is formed along the axial direction on one short side along the axial direction. A single slit 60b is formed along the axis on the bottom surface of the groove 60a, extends to the tip of the tube 60 on the vehicle body side, and the slit 60b is formed along the entire length of the tube 60 in the axial direction. The wire harness 40 in which the connector 50 is connected to the tip from the side perpendicular to the axial direction of the tube 60 can be inserted into the tube 60 by forcibly opening and widening both sides across the slit 60b. I am doing so. When the forcible opening is released after the wire harness is inserted, both side portions return to the original shape joined with the slit 60b therebetween, and the outer periphery of the wire harness can be surrounded and protected.

An annular locking protrusion 60c protruding in a flange shape is protruded from the opening periphery of the tube 60 on the vehicle body side.
