Description

  The present invention relates to a wiring structure for providing electrical wiring from a vehicle body to a door.

  For example, the conventional wiring structure for wiring harnesses that are routed from the vehicle body to the back door has an elliptical shape on both sides that incorporate the grommet's resin inner, and from the bent position of the tube to the tip of the opening of the mounting Is set smaller than the diameter of the through hole provided on the vehicle body side and the door side, and the mounting portions on both sides of the grommet are twisted 90 degrees in the through hole on the vehicle body side or door side to be passed through, and the through hole is formed. On the other hand, the mounting part opening surface is made to pass through in a substantially orthogonal direction, and after passing through, both mounting parts are returned 90 degrees, and the through hole on the vehicle body side and the door side and the both mounting part opening surfaces are made substantially parallel and pushed into the through holes, respectively. It is known that the resin is locked with the inner resin (see Patent Document 1). According to this, the wire harness of the grommet mounting part between the vehicle body and the door can be continuously formed without being separated from the vehicle body side harness or the door side harness. As a result, the previously separated harness can be continued, the number of wire harness parts can be reduced, the number of accessories such as connectors can be reduced, and connector connection work is no longer necessary. Cost reduction.

As another conventional example, as shown in FIGS. 3 and 4, the vehicle body 1 and the door 2 are connected by a hinge 3, and the wire harness W on the vehicle body 1 side is routed to the door 2 side through the grommet 4. It was.

  Conventionally, it has been necessary to make routing holes in the metal parts of the vehicle body and doors, and the use of grommets has increased the number of parts and the routing work has been troublesome.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a vehicle body and door routing structure that eliminates the need for waterproofing using grommets, reduces the number of parts, and facilitates routing work.

  In order to achieve the above-mentioned object, the present invention provides a weather strip on the vehicle body side for waterproofing the opening and closing hinges between the vehicle body and the door, and routes the flexible printed circuit board inside the door trim, and this flexible printed circuit board is connected to the door trim. The wire harness is inserted into the insertion port of the vehicle body through the inside of the weather strip and connected to the wire harness routed inside.

  According to the present invention, a weather strip is provided on the vehicle body side in order to waterproof the opening and closing hinges between the vehicle body and the door, the flexible printed circuit board is routed inside the door trim, and the flexible printed circuit board is connected to the weather strip from the door trim outlet. Inserted into the insertion port of the vehicle body through the inside and connected to the wire harness routed inside, eliminating the need for grommets and eliminating the need for special waterproofing means, reducing the number of parts and making the wiring work easier It becomes. In addition, it is easier to form the outlet in the door trim than to make a hole in the metal part. In addition, the flexible printed circuit board is wired with a surplus length to enable expansion and contraction and bending at the hinge location.

  Preferred embodiments of the present invention will be described below with reference to the drawings.

  In FIG. 1, a weather strip 6 is provided on the side of the vehicle body 1 near the door trim 5 on the door 2 side in order to waterproof the opening and closing hinges between the vehicle body 1 and the door 2 (in this example, a minivan back door is assumed). A flexible printed circuit board (FPC) 7 is routed inside the door trim 5, and this FPC 7 is routed from the outlet 5A provided in the door trim 5 to the insertion port 1A of the vehicle body 1 through the inside of the weather strip 6 and the lower side in this drawing. In addition, a wire harness (not shown) is connected inside the vehicle body 1. The door trim 5 is usually a resin molded product, and the outlet 5A can be easily formed by forming a recess in the joint portion with the door body.

  In FIG. 2, only the part where the hinge 3 of the vehicle body 1 is attached protrudes from the other parts, and the positional relationship between the attachment part of the hinge 3, the outlet 5A of the FPC 7 and the insertion opening 1A is set on substantially the same plane. is there. Thereby, the degree of expansion / contraction accompanying opening and closing of the door 2 of the FPC 7 can be reduced. As shown in FIG. 2, the present invention can be implemented even when the attachment portion of the hinge 3 is not protruded from other portions.

  Although only the weather strip 6 provided on the vehicle body 1 side is shown in the drawing, it may be provided on the door 2 side. In a state where the door 2 is closed, the FPC 7 is located inside the weather strip 6 (inside the vehicle compartment), so that the FPC 7 is protected from rainwater from the outside. In the embodiment of FIGS. 1 and 2, since the back door 2 of the minivan is assumed, the left end of FIG. In addition, it is applicable also to the door 2 for normal vehicle getting on / off.

The side view which shows embodiment of this invention. The perspective view of FIG. The side view which shows a prior art example. FIG. 4 is a perspective view of FIG. 3.
