Description

  The present invention relates to a wiring structure for a door harness, and more specifically, in a door harness that is routed between a side door and a vehicle body on the indoor side from a weather strip, due to a twist that occurs in each door opening / closing operation in the door harness at the transition portion. It is intended to prevent fatigue / damage.

  Conventionally, when electrical components are attached to the side door of an automobile, the door harness that is routed to the side door and pulled out to the vehicle body side is routed in a space constituted by the door outer panel and the door inner panel, A grommet is externally attached to the crossing part to the vehicle body, and the vehicle body locking portions provided at both ends of the grommet are fitted and locked to the through holes formed in the vehicle body side end surface of the door panel and the through holes formed in the vehicle body panel. ing.

  The operation of penetrating the wire harness through the through-hole formed in the panel is very difficult. In addition, the conventional door harness is routed between the vehicle body and the door in the vicinity of the rotation axis of the hinge H. When the door is opened and closed, the wire harness is only bent and twisted, and does not generate expansion and contraction. Is provided on the outdoor side of the weather strip. Therefore, it is necessary to attach the grommet to the through-hole of the wire harness in a waterproof state in the through hole, and there is a problem that labor is required for mounting the grommet into the through hole.

In order to solve the above problem, the present applicant previously provided a wiring harness wiring structure shown in FIG. 6 in Japanese Patent Laid-Open No. 10-934 (Patent Document 1). In this wiring structure of the wire harness, a substantially triangular space 1c is provided on the inner side surface of the inner panel 1a of the door 1, while the wire harness W / H is provided with an extra length portion that can follow the door opening and closing. The long portion is accommodated in the space 1c and pulled out from the outlet of the space 1c to the vehicle body side.
With this configuration, when the door is opened, the wire harness W / H is pulled out of the space 1c. When the door is closed, the extra length of the wire harness W / H is accommodated in the space 1c. Can be made to follow the door opening / closing operation. Moreover, since the wire harness W / H is routed indoors from the weather strip 4, there is no need to provide a waterproof structure.

  As described above, in the structure of Patent Document 1, the wire harness W / H can be pulled out to the vehicle body side without passing through the through-hole of the inner panel 1a on the door 1 side, but at the transition portion between the door and the vehicle body. The door harness needs to be twisted according to the opening / closing operation of the door. For this reason, it has been proposed to attach an exterior member that generates a twist in the door harness at the transition portion. However, since the twisting operation is repeated according to the opening and closing of the door, there is a possibility that the exterior member comes into contact with the door harness every time the twisting operation is performed, and contact fatigue occurs in the door harness to cause damage.

Japanese Patent Laid-Open No. 10-934

  The present invention has been made in view of the above problems, and it is an object of the present invention to reduce fatigue of the door harness at the transition portion between the door and the vehicle body and to prevent occurrence of damage.

In order to solve the above-mentioned problem, the present invention includes an exterior protective material that inserts and holds a door harness that extends from the door inner panel side to the vehicle body side through the interior side of the weather strip on the vehicle body side,
The exterior protective material has a portion extending in the vertical direction on the vehicle body mounting side, and is wired in the vertical direction through the door harness to the wiring hollow portion of the vertical extending portion, and the inside of the vertical wiring hollow portion The door harness routing structure is characterized in that the door harness is twisted and rotated when the door is opened and closed.

  In this way, when the door harness is routed from the weather strip to the indoor side, the torsional motion that occurs in the door harness to follow the door opening / closing operation is not performed at the crossover part, but is fixed to the vehicle body side. A door harness is wired in the vertical direction inside the protective material and is rotatable around the vertical axis so that the door harness is twisted by following the door opening / closing operation. Therefore, since the door harness is only twisted in the wiring hollow portion of the exterior protective material, it can be prevented from being worn and damaged due to contact with other members.

Specifically, the exterior protective material is connected to a vehicle body side tip of a grommet that is externally mounted on a crossing portion between the door and the vehicle body of the door harness, and the door harness is inserted and held on the vehicle body side, and the door facing surface of the vehicle body Guide the door harness that goes over the flange protruding from the inner side of the inner panel of the car body,
The exterior protective material is
A vehicle body side fixing portion that is connected to the vehicle body side of the grommet and extends in the vertical direction along the door facing surface, and a fixing portion is provided on the upper side portion;
A flange outer fitting portion that is continuous with the lower side portion of the vehicle body side fixing portion, and that is externally fitted to a flange of a joint portion between the vehicle body outer panel and the vehicle body inner panel;
In the wiring hollow portion provided in the vehicle body side fixing portion and the flange outer fitting portion, the door harness is routed in the vertical direction in the vehicle body fixing portion, and then passed through the flange outer fitting portion, from the tip of the flange outer fitting portion. It is routed on the interior side of the car body inner panel,
The door opening and closing operation is configured to follow the upper and lower wiring hollow portions by twisting the doorness.

In the door harness routing structure provided with the exterior protection material described above, the door harness is pulled out from the door and passed to the vehicle body, and the door harness is externally attached to the inner surface side of the vehicle body inner panel along the door facing surface on the vehicle body panel side. The body side fixing part that fixes the exterior protection material to the vehicle body panel has a shape extending in the vertical direction, and the door harness inserted through the vertical part is twisted when the door is opened and closed. Thus, the door harness is made to follow the opening and closing operation of the door.
In this way, since the exterior protection material attached to the vehicle body is provided with the torsional motion allowing portion of the door harness, it is not necessary to provide a mechanism that allows the door harness to be twisted at the transition portion between the door and the vehicle body. The wiring structure can be simplified.
In addition, the flange outer fitting portion is continuously provided on the lower end side of the vehicle body side fixing portion, and the door harness is inserted into the hollow portion of the flange outer fitting portion, so that the door harness is protected. Can be routed to the surface side.
The door harness extension part is routed from the weather strip to the interior side of the weather strip, and the door harness expansion and contraction mechanism occurs when the door is opened and closed by positioning the door from the hinge position between the door and the body. I have it on the side.

  In the door harness routing structure, there is no need to pass the door wire harness that spans between the door and the vehicle body through the through-hole formed in the panel on the vehicle body side. As a result, the door harness assembly workability can be greatly improved. In addition, conventionally, in order to lock the tip of the grommet that covers the crossover portion of the door harness in the through hole of the vehicle body panel, a resin inner is assembled to the grommet, and the engaging portion provided in the resin inner is engaged with the through hole.

  Specifically, the outer protective material is a combination of an outer cover and an inner cover, and is provided with the flat wiring hollow portion through which the door harness is inserted, and the upper portion of the inner cover constituting the vehicle body side fixing portion. A clip for locking the vehicle body serving as the fixing portion protrudes and is inserted and locked into a locking hole of the vehicle body side panel, while the grommet is locked to the outer cover at a position opposite to the clip protruding portion. A hole is provided, and the wire group of the door harness is wired in parallel through the hollow portion for wiring.

It is preferable that the outer cover and the inner cover of the exterior protective material are resin molded products, respectively.
According to the said structure, since the exterior protection material is comprised by the separate outer cover material and inner cover material, in the state which wired the door harness to the inner surface of the outer cover material or the inner cover material, the outer cover material and the inner cover By assembling the materials, the door harness can be easily wired in the flat wiring hollow portion between the outer cover material and the inner cover material.
In addition, since the door harness is bent and wired at the flange outer fitting of the exterior protective material, even if the door harness swings when the door is opened and closed, this swing is absorbed by the bent portion of the door harness. can do.

  Moreover, since the electric wire group of the door harness is parallelly wired and inserted through the inside of the outer cover and the inner cover, the exterior protective material can be flattened and the amount of protrusion can be reduced. In this way, by reducing the amount of protrusion, it is possible to suppress the occurrence of contact with the occupant and make it less visible on the appearance.

  The grommet that fits outside the door harness between the door and the vehicle body is provided with a bellows tube, and the grommet is pulled out from the interior side of the door inner panel and passed from the weather strip to the vehicle body panel through the interior side. On the vehicle body side, it is positioned on the door facing surface on the vehicle compartment side from the contact position with the weather strip, and is connected and locked to the vehicle body side fixed portion of the exterior protective material at the vehicle body side tip of the bellows tube portion, and the door side panel Are routed without penetrating both the through hole and the through hole of the vehicle body side panel.

In this way, if the wire harness is routed without penetrating through the through hole in either the door or the vehicle body, the wiring operation of the door harness becomes very easy, and the fixing of the door harness to the vehicle body side is clipped. It can be done with one touch.
Furthermore, since the door harness with the grommet is passed through the room side from the weather strip, it is not necessary to take a waterproof measure.
When the wire harness of the crossing part that covers the grommet is routed below the door checker (about 50 to 100 mm), the grommet is protected by the door checker and the occupant can be prevented from coming into contact with the grommet. it can.

In place of the exterior protective material that inserts and protects the door harness without penetrating on the vehicle body side described above, even in the type that pulls out into the vehicle body that penetrates the door harness to the through hole drilled in the door panel on the door facing surface on the vehicle body side, The present invention can be applied.
In this case, the exterior protective material that is exteriorly mounted on the door harness is externally installed at a connecting portion between the door and the vehicle body of the door harness, and is inserted and locked in a through hole formed in the vehicle body outer panel on the door facing surface. Consisting of grommets,
The grommet through-hole insertion portion has a shape in which the wiring hollow portion in the vertical direction extends, and an insertion port for the crossover door harness is provided on the upper side, and the vehicle body is provided below the insertion port and the opposite side wall. An outlet to the inside is provided, and the door harness extends in the vertical direction in the vertical wiring hollow portion.

  With the above configuration, it is not necessary to provide an exterior protective material on the vehicle body side separately from the grommet that is externally mounted on the crossover portion of the door harness, and the vertical wiring hollow portion that extends through and is fixed to the through hole on the vehicle body side is extended. It is only necessary to form the through-hole insertion part integrally, and the number of parts can be reduced.

The vertical dimension of the wiring hollow portion is larger than the vertical dimension of the connector connected to the front end of the door harness pulled out from the outlet, so that the vertical direction is formed in the vertical wiring hollow portion. When the wired door harness is torsionally operated, it is possible to prevent the influence of torsion from reaching the connection side with the connector connected to the front end of the door harness.

  As described above, according to the door harness routing structure of the present invention, the upper and lower wiring portions are provided on the exterior protective material through which the wire harness extending from the door to the vehicle body is inserted on the vehicle body side. Thus, the door harness can be twisted to follow the opening / closing operation of the door. Therefore, it is not necessary to generate a twisting motion in the door harness at the transition portion between the door and the vehicle body, and it is not necessary to provide an exterior protective material that can follow the torsional motion of the door harness on the door harness. It is possible to prevent fatigue and damage to the door harness.

  In addition, as an exterior protection material on the vehicle body side, when an exterior protection material that guides along the door facing surface and passes over the flange protruding from the door facing surface and is routed to the inner surface of the vehicle body inner panel, The door harness can be prevented from penetrating on both sides of the door, and the door harness can be easily routed.
