DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness wiring structure for a hatchback glass of an automobile, and more particularly, to a rear harness attached to a lower end of the hatchback glass.
The drive harness of the wiper is wired from the body side along the inner surface of the hatchback glass.

[0002]

2. Description of the Related Art As shown in FIG. 6, in a hatchback type automobile, a hatchback glass (hereinafter abbreviated as "glass") 1 is attached to an upper frame of a body 8 via a hinge, and the glass 1 is opened and closed vertically. Stuff is provided. A rear wiper 3 and a wiper motor 5 are attached to the center of the lower end of this type of openable / closable glass 1, and a harness 4 for driving the wiper motor 5 is provided at the center of the upper frame of the body 8. It is routed along the inner surface of the glass 1.

As shown in FIG. 7, a harness 4 arranged on the glass 1 accommodates a plurality of electric wires w wired from the upper frame side of a body 8 in a protector 6 made of resin.
The protector 6 is adhered to the inner surface of the glass 1 via an adhesive 7. At that time, the harness 4 needs to be routed from the upper edge of the glass 1 to the lower edge via one side edge, and since the distance is long, a single protector increases the size and the upper edge and the lower edge. The protector 6 is composed of the straight portions 6A, 6B, 6C and the curved portions 6D, 6E because the side edges and the connecting portions to the side edges are curved so that integral molding is not easy.
They are molded separately and used by joining them.

The above-described protector 6 has a straight portion 6
A to 6C are formed by extrusion molding using PVC, while the curved portions 6D and 6E are formed by injection molding using PP. Each part 6A-6E of these protectors 6
As shown in FIG. 8, a lid 6c is provided at the upper end of one side wall of the gutter-shaped main body 6a via a thin hinge 6b.
After passing the electric wire w through the main body 6a, the lid 6c is closed, and the lid 6c and the main body 6a are locked and locked.

[0005]

With the above-described wiring harness wiring structure, the protector 6 uses five separate parts, so that the number of parts is large and the cost is high, and the wires of the protector 6 are connected to these protectors. There is a problem that the number of man-hours for mounting and mounting each protector on the glass increases.

Furthermore, since the straight portions 6A to 6C and the curved portions 6D and 6E are made of different resin, a difference occurs in the adhesive strength to glass, and there is a problem in the reliability of fixing the protector to glass. In particular, PP constituting the curved portions 6D and 6E has a problem of poor adhesiveness. Furthermore, the opaque black coating is applied to the inner surface of the glass to prevent these protectors from being viewed from the outside, but the structure where the protectors are connected in order from the inside can be seen, and the appearance is not good. There is also.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems. First, a harness exterior material is not connected to another component, but is a continuous component, thereby reducing the number of components and the number of mounting steps. The challenge is to improve the appearance.

[0008]

In order to solve the above-mentioned problems, the present invention is characterized in that, in claim 1, a flat portion for bonding and fixing is provided at least in a part in a circumferential direction, and the flat portion is arranged in a longitudinal direction. A continuous resin corrugated tube is provided, a wire group arranged on the inner surface side of the hatchback glass of the vehicle is passed through the corrugated tube, and the flat portion of the corrugated tube is fixed to the hatchback glass via an adhesive. The present invention provides a wiring harness wiring structure for hatchback glass of an automobile.

More specifically, the corrugated tube has a rectangular, semi-annular, or triangular cross section in cross section, and the corrugated tube is provided with a plurality of irregular portions provided alternately on the outer peripheral surface thereof for bonding and fixing. The tip surface of the convex portion located on the flat portion is a flat surface.

That is, if a corrugated tube is used as a bellows shape by providing an uneven portion on the outer peripheral surface, the corrugated tube can be easily curved, and therefore, as a wire harness exterior material that is curved and routed along the inner surface of the hatchback glass. It can be suitably used. However, the corrugated tube used as the exterior material of the conventional wire harness has an annular shape, and if this annular corrugated tube is adhered to the hatchback glass with an adhesive, it can be adhered only in a linear shape, and it is not reliable. There is a problem that securing cannot be secured.
For this reason, in the present invention, the corrugated tube is not formed into a ring shape in cross section, but is provided with a flat portion at least in a part in the circumferential direction, and the flat portion is adhered to glass via an adhesive, thereby forming a planar shape. Adhesion is possible over a wide area.

As described above, since it is sufficient to provide a plane portion that can make surface contact with at least a part of the circumferential direction, a rectangular cross section, a semi-annular frame, a triangular frame, or the like can be appropriately used. In addition, even if the conventional annular frame is a rectangular frame, a semi-annular frame, or a triangular frame, if the convex end of the concave / convex portion on the peripheral surface is curved, an adhesive area cannot be obtained, so that the convex end surface is flat. It has a face.

According to a third aspect of the present invention, while a group of electric wires routed on the inner surface side of the hatchback glass of an automobile is passed through a resin corrugated tube, a holding portion for fitting and holding the corrugated tube and an adhesive fixing portion are provided. To a hatchback glass of an automobile, wherein a fixing member having a flat portion is attached to the corrugated tube at an interval, and the flat portion of the fixing member is fixed to a hatchback glass via an adhesive. The wiring harness wiring structure is provided.

That is, in the third aspect, a conventionally provided annular corrugated tube is used, and the corrugated tube is fixed to the hatchback glass at intervals by a fixing member having a flat portion for bonding to glass. I have. With this configuration, a commonly used corrugated tube can be used as it is, and the cost can be reduced. The fixing member is a block body made of resin and having a triangular cross section,
A concave portion for corrugated tube insertion is provided at the upper apex of the corrugated tube, and the corrugated tube is forcibly inserted and held in the concave portion. The lower flat surface portion of the block body is used as an adhesive flat surface portion, and is adhered and fixed to glass via a double-sided adhesive tape or the like.

It is preferable that the electric wire group inserted into the corrugated tube according to any one of the first to third aspects is a tubed wire previously inserted into the tube (claim 4). That is, a group of wires arranged on the hatchback glass is composed of four wires for connection to the rear wiper motor, and a tubed wire having a configuration in which the four wires are inserted in a tube in advance has been conventionally provided. Therefore, when this tubed wire is used, the laying workability can be improved. Moreover, since the electric wires are protected by the tubes even in the corrugated tube, the protection performance of the electric wires can be further improved. It is needless to say that the wire group may be passed through the corrugated tube as it is without using the tubed wire.

And a rear wiper 3 and a wiper driving motor 5 are attached to the center of the lower end.

As the harness, the tubular wire 11 is used.
The tubed wire 11 is formed by inserting four electric wires w into a tube 12 made of an insulating resin, and this tubed wire is conventionally provided.

The above-mentioned tubed wire 11 is made of glass 1
The exterior is covered with one continuous corrugated tube 15 that is continuously arranged along the inner surface of the member. The corrugated tube 15 is formed of a resin, and has a bellows shape on its outer peripheral surface in which convex portions 15a and concave portions 15b in the circumferential direction are formed alternately and continuously in the axial direction as in the conventional case. Therefore,
The corrugated tube 15 itself is configured to be easily bent. The convex portion 15a protrudes in a trapezoidal shape, and its distal end surface 15c is a flat surface.

The corrugated tube 15 is formed of a rectangular frame as shown in the figure, and each side (specifically, the projection end face 15c of each side) forms a plane. Therefore, any side can be used as an adhesive fixing surface to glass, and the direction of the corrugated tube 15 is not restricted.

With the tubed wire 11 inserted through the corrugated tube 15, the lower side of the corrugated tube 15 is used as an adhesive fixing surface 15 d, and a double-sided adhesive tape 18 coated with an adhesive 18 a on both surfaces is used as the lower adhesive bonding surface. 15d is attached to the projection end surface 15c.
