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, as shown in FIG. 16, the wire harness routed between the vehicle body and the side door is connected to the body 3 side through the through hole 1b formed in the end surface of the inner panel 1a of the door 1 on the vehicle body side. (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 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. 17, a substantially triangular space 1 c is provided on the inner side surface of the inner panel 1 a 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 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, 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. 18, 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 fitted. 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 and suppresses the generation of abnormal noise.

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,
The connector and the wire harness are penetrated through a hollow portion in which a protective material is made of a hard resin tube and a hard resin offset cylinder portion having a lower portion rotatably connected to a vehicle body side end of the tube. ,
A connector outlet is provided on an upper side surface of the offset cylinder portion connected to stand upright with respect to the tube disposed in a horizontal direction between the vehicle body and the door, and the connector outlet is provided on a peripheral edge of the connector outlet. An annular projection provided with a fitting groove for fitting and locking the locking projection provided on the rear side portion of the connector is provided, and the vehicle body is sandwiched between the annular projection and the vehicle body locking portion of the connector. The wire harness routing structure is characterized in that the connector is engaged with and connected to the connector at the tip of the wire harness routed on the vehicle body side.

As described above, in the present invention, the protective material for the wire harness bridged between the door and the vehicle body is not made of rubber, but is made of a hard resin offset cylinder and tube to increase the protective strength of the wire harness, and When the door is closed, the wire harness passed through the tube is prevented from hanging between the door and the vehicle body.
In particular, the connector connected to the tip of the wire harness is fixed to the offset cylinder in a state protruding from the connector outlet of the offset cylinder, and the tip of the offset cylinder is fixed to the vehicle body panel. Thus, the connector can also be fixed inside the vehicle body side through hole. Therefore, when connecting the wire harness on the door side and the wire harness on the vehicle body side, it is only necessary to fit the connector at the tip of the vehicle body side wire harness to the connector on the door side wire harness. There is no need to lock and hold the vehicle body via a clip or the like.

In addition, according to the above configuration, when the door is opened and closed, the tube through which the wire harness is inserted rotates at the connection position with the offset cylinder portion. Can be absorbed.
In addition, the twisted position of the wire harness accompanying the opening and closing of the door is offset by the offset cylinder part below the connection position between the wire harness and the connector, so the load caused by twisting is near the connector connection position of the wire harness. There is no risk of impairing the reliability of the electrical connection.

The connecting portion between the tube of the protective material and the offset cylinder portion is provided with a connection port on the lower side surface of the offset tube portion, and a pair of upper and lower mounting portions projecting from the upper and lower edges of the connection port, Protruding a pair of upper and lower mounted parts that overlap the mounting part from the upper and lower edges of the tube end opening,
It is preferable that a pin hole is provided on either one of the attachment portion and the attachment portion, and a pin hole for rotatably inserting the pin is provided on the other.

  According to the said structure, the said wire can be rotated by using the pin inserted rotatably in the said pin hole as a fulcrum, and the twist of the wire harness accompanying opening and closing of a door can be absorbed.

Further, the connecting portion between the tube of the protective material and the offset cylinder portion is provided with a connection port by notching the lower side surface of the offset cylinder portion, while the top end of the tube is a closing portion and the upper surface is an opening, A closed portion at the tip of the tube is fitted into the connecting port, and the opening on the upper surface is communicated with the hollow of the offset cylinder portion.
A circular groove is provided on one of the bottom surface of the connecting port of the offset cylinder portion and the bottom surface of the closing portion at the tip of the tube, and a circular protrusion that rotatably fits in the circular groove portion is provided on the other. It is good also as a provided structure.

  According to the said structure, the tube can be rotated centering | focusing on the circular protrusion rotatably fitted to a circular groove part, and the twist of the wire harness accompanying opening and closing of a door can be absorbed. In addition, since the tip of the tube is fitted in the connecting port of the offset cylinder part, the wire harness is prevented from being exposed at the connecting position between the tube and the offset cylinder part, thereby protecting the wire harness more reliably. At the same time, the appearance can be improved.

  It is preferable that 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.

According to the said structure, since the width | variety of the horizontal direction orthogonal to a length direction can be made thin, a wire harness can be efficiently routed in the limited space between a vehicle body and a door.
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.

The tube is preferably a straight tube, and if it is a straight tube, the tube can be moved in a straight line during movement associated with the door opening / closing operation inside the door, and the wire harness following operation for the door opening / closing operation is ensured. It can be.
Moreover, it is preferable that a tape winding tongue piece protrudes from the end of the tube on the door side and the wire harness is fixed with tape.

  The tube and the offset cylinder part have a thin hinge part extending along at least a part of the axial direction, and can be opened and closed by the thin hinge part, and the wire harness and the offset cylinder part are opened with the tube and the offset cylinder part being opened. It is preferable that the connector is inserted and closed by lock coupling.

  In addition, the tube and the offset cylindrical portion may have a shape having a slit along the axial direction, and the slit may be opened to allow the wire harness and the connector to be inserted into the tube from the side. The offset cylinder portion may be divided into two parts along the axial direction, and the wire harness and the connector may be inserted into one of the divided tubes and then covered with the other divided tube to lock the two tubes together.

  When a wire harness with a connector connected to the tip is passed through the tube and offset cylinder, the tube and offset cylinder are hard, so the wire harness cannot be passed while being expanded with a diameter-enlarging jig like a rubber tube. . Therefore, if the tube and the offset cylinder part have a cylindrical shape with a closed cross section, it is necessary to make the tube and the offset cylinder part larger than the outer shape of the connector, and even if the tube is enlarged, the tube and the offset cylinder part are penetrated into the long tube. The work is troublesome. Therefore, it is possible to adopt a method in which only the wire group of the wire harness is passed through the tube and the offset cylinder part, the wire group is drawn from the tip opening of the tube, and the terminal of the wire terminal is inserted and locked to the connector. As described above, the tube and the offset cylinder part can be opened and closed freely, provided with a slit, or a divided body, and the wire harness in which the connector is connected from the side perpendicular to the axis of the tube and the offset cylinder part is placed in the tube. The wire harness can be passed through easily.

The tube is slidably accommodated in a guide portion provided on the door,
The wire harness drawn from the tube is provided with a surplus length portion that can follow the opening and closing operation of the door, and the surplus length portion is accommodated in a surplus length absorbing space provided in the guide portion. It is preferable that the wire harness is locked to the door side at the exit position of the long absorption space.

According to the above configuration, when the door is opened, the wire harness extends by being pulled out of the extra length of the wire harness drawn into the extra length absorption space of the guide portion, while the extra length is obtained during the closing operation. The wire harness expands and contracts when the portion is drawn into the extra space absorption space, and follows the opening / closing operation of the opening / closing member.
At the time of the opening and closing operation of the wire harness, the wire harness is passed through the hard resin tube, so the tube integrated with the wire harness moves linearly, and the extra length of the wire harness is extra length. The wire harness can be reliably pulled out from the absorption space and can be reliably pulled into the absorption space for excess length, and the wire harness can be made to follow the opening / closing operation of the opening / closing member.
Furthermore, when the tube is a cylindrical hard resin molded product and its outer peripheral surface is a smooth surface, the tube is in sliding contact with the guide portion, so that the generation of abnormal noise can be reduced.

  Specifically, the guide portion is continuously provided with a sliding space for slidably housing the tube and the surplus length absorption space for curving and accommodating the surplus length portion of the wire harness. It is preferable that the protector is formed of a substantially triangular protector made of a product, and the protector is fixed to the door side.

As described above, the guide portion is formed of a shallow triangular protector, and the protector is fixed to the door inner panel with screws or the like. The protector has an opening on the indoor surface side and is covered with a door trim with a wire harness routed inside.
More specifically, the substantially triangular protector has a peripheral wall projecting from each side of the bottom wall portion, the upper peripheral wall is straight, and the front side wall is arranged with a linear slide space therebetween. The side peripheral wall is gently curved downward, and the other side peripheral wall is gently curved so as to be close to the distal side peripheral wall. While an opening for entrance is provided at the tip of the slide space, a lower end opening between the pair of side peripheral walls is used as a drawer opening to the inside of the door, and a large volume portion extending from the slide space to the drawer opening is excessive. It is a long absorption space. In addition, the entrance / exit opening at the tip of the slide space is preferably provided with a closed wall between the upper side peripheral wall and the side side peripheral wall, and a through hole is provided in the closed wall as the entrance / exit opening.
If the guide part is formed by the protector as described above, the space for sliding and the extra length absorbing space of the required dimensions can be provided with high dimensional accuracy, and there is no need to change the structure of the inner panel and the door trim from the conventional one. Assembling property can be improved.
In addition, the protector is provided with an upper wall portion facing the bottom wall portion without opening the indoor surface side, and an opening is provided on one of the sides of the peripheral wall, and the wire harness is connected to the protector through the opening. After opening the cable, the opening may be closed with a cover. Thereby, it can prevent that the wire harness in a protector contacts a door inner panel and a door trim directly by the said bottom wall part and an upper wall part.
Instead of providing the guide portion with a protector made of a separate material, a wire module is routed and a door module panel for preinstalling electrical components connected to the wire harness is provided. It is good also as a guide part by providing the recessed part of the shape similar to a protector.

It is preferable that a holding portion for allowing the tube to pass through the guide portion in a slidable manner while being linearly protruded from the door member.
According to the said structure, a tube can be slid linearly with the holding | maintenance part provided in the entrance side of the guide part, and a wire harness can be made to follow a door opening / closing smoothly.

  The present invention can be applied not only to the side door, but also between the back door and the vehicle body, between the trunk lid and the vehicle body, etc. It is preferable that the guide portion is provided on the indoor side surface of the inner panel of the door, the tube pulled out from the guide portion passes through the indoor side of the weather strip, and the wire harness is bridged to the body side.

  As described above, when the present invention is applied to the structure in which the door harness routed to the side door is routed on the vehicle body side, the door harness is routed on the indoor side rather than the weather strip. The operation of inserting the through hole provided in the end face of the wire harness becomes unnecessary, and the wiring workability of the wire harness can be greatly improved.

As described above, according to the present invention, when the door is opened and closed, the tube through which the wire harness is inserted rotates at the connecting position with the offset cylinder portion. Can absorb the twist.
In addition, the twisted position of the wire harness accompanying the opening and closing of the door is offset by the offset cylinder part below the connection position between the wire harness and the connector, so the load caused by twisting is near the connector connection position of the wire harness. There is no risk of impairing the reliability of the electrical connection.
Furthermore, since the wire harness spanned between the vehicle body and the door is protected by a tube made of hard resin, the wire harness can be prevented from hanging down or being inadvertently damaged between the vehicle body and the door. .
Further, the connector protrusion connected to the end of the wire harness is fitted and locked in the fitting groove of the offset cylinder part to fix the connector to the offset cylinder part, and the annular provided on the offset cylinder part Since the protrusion and the vehicle body locking portion provided on the connector pinch the periphery of the through hole provided in the vehicle body, when the offset cylinder portion is attached to the vehicle body, the connector is also attached to the vehicle body at the same time. As a result, it is not necessary to newly provide a structure for fixing the connector connected to the vehicle body side terminal of the wire harness routed to the door to the vehicle body, the cost can be reduced, and the wiring work of the wire harness can be facilitated. be able to.

In addition, if a tube made of hard resin is passed through the interior side of the weather strip and an extra length is provided in the wire harness so that it can follow the opening and closing of the door, the wire harness routed between the door and the vehicle body is connected to the door. Provided at a position away from the rotation fulcrum (hinge position) with the vehicle body, it can be a so-called penetration-less type in which the wire harness does not pass through the through-hole drilled in the door, and wiring work of the wire harness can be facilitated. .
In addition, when the wiring structure is used, it is necessary to expand and contract the wire harness with the opening and closing operation of the door. However, since the wire harness is inserted into and out of the door through the tube, the wire harness is slackened. In addition, the surplus length portion of the wire harness can be reliably and smoothly accommodated and pulled out in the surplus length absorption space of the guide portion on the door side. And the resistance at the time of operation | movement of this wire harness can also be reduced, and noise generation can be reduced.
