Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure for a wire hatch of a glass hatch in a back door of an automobile, and more particularly, to a method of easily attaching a wire harness to a glass hatch without using a double-sided adhesive tape or the like. In addition, the cost for mounting the wire harness is reduced.

[0002]

2. Description of the Related Art A rear wiper, a defogger and the like are attached to a glass hatch, and a wire harness for supplying power and the like for operating the rear wiper and the like is routed from the vehicle body to the glass hatch. . This routed wire harness is routed to required connection points on the glass hatch surface.

FIG. 9A shows a wiring harness W / H arrangement structure on a surface of the glass hatch 1 on the indoor side. The wire group D constituting the wire harness W / H routed from the vehicle body is housed in the protector 2 and routed to the connection portion C1 of the motor portion 8 of the rear wiper, and branches off in the middle to defog. 9 are also connected.

FIG. 9B shows the above-mentioned wire harness W / H.
2 shows a state in which the protector 2 accommodating the protector 2 is fixed to the glass hatch 1. One side of the double-sided adhesive tape 5 is attached to the bottom surface of the protector 2 and the double-sided adhesive tape 5
Is attached to the routing path of the wire harness W / H on the indoor side surface 1a of the glass hatch 1, the protector 2 is fixed to the glass hatch 1, and the wire harness W / H is routed to the glass hatch 1. ing.

[0005]

With the above wiring harness routing structure, since the double-sided adhesive tape is used for fixing the protector, the protector is bonded to match the routing route on the glass hatch surface. However, there is a problem that it requires attention and takes a long time for mounting work. Further, once the double-sided pressure-sensitive adhesive tape is pasted and then peeled off, the adhesive strength is reduced, so that the double-sided pressure-sensitive adhesive tape cannot be reattached again, and there is a problem that the position of the tape cannot be easily corrected. In addition, the cost of the double-sided pressure-sensitive adhesive tape itself used for the above-mentioned pasting is large, and the double-sided pressure-sensitive adhesive tape once pasted cannot be reused.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problem, and has been made to enable the wire harness to be fixed to the glass hatch without using a double-sided adhesive tape, and to improve the ease of installation work. It is an issue.

A fitting recess 11b is provided on one side of the glass hatch 11 so as to extend along one side edge. It is provided so as to extend to the motor unit 18. Further, the recessed portion 1 is formed in the side wall 11d on both sides of the fitting recess 11b.
1e is provided. Note that one side of the glass hatch where the fitting recess 11b is provided is provided on one side of the side closer to the connectors C10 and C20. Therefore, if the type of vehicle is different, the fitting recess may be provided at a location other than the above. For example, if the connector is located at the upper end, the fitting recess may be provided along the upper edge.

The fitting recess 11b and the recess 11e
Is adapted to the cross-sectional shape and dimensions of the tubed wire 13 described above, and the recess 11b serves as a stopper when the tubed wire 13 is fixed.
1b may be slightly larger than the cross-sectional dimension of the tubed wire 13 so that it can be easily fitted.

A through hole 11c for a wire harness is provided at the upper end of one side where the fitting concave portion 11b is provided. The hole 17 is inserted into the interior surface 11a of the glass hatch 11 on the indoor side. When the wire harness is routed from the indoor side directly to the indoor surface 11a of the glass hatch 11, the through hole 11
It is not necessary to provide c.

FIGS. 5A and 5B show the above-mentioned glass hatch 1.
An example of formation of one fitting recess 11b and depression 11e is shown. Tops 16a, 16b, 16 having the same shape and the same cross section as the set dimensions of the fitting recess 11b and the like.
c is disposed on one side and the lower end of the glass hatch 11 where the fitting concave portion 11b is provided.
Are formed, the tops 16a, 16b, and 16c are sequentially removed to form the fitting recess 11b and the recess 11e. The glass hatch 11 may be formed other than the above example.

Further, the cross section of the fitting recess 11b is not limited to the above-mentioned shape, but is shown in FIGS. 4 (A), 4 (B) and 4 (C).
6 (A), 6 (B), and 6 (C), it may be formed into a substantially triangular shape, a substantially trapezoidal shape, or a substantially circular shape in accordance with various cross-sectional shapes of the tubular wire 13 shown in FIG. .

In order to arrange the wire harness W / H formed as the tubed wire 13 in the fitting recess 11b of the glass hatch 11 formed as described above, as shown in FIG. 11 into the fitting recess 11b. Since the tubed wire 13 is formed of flexible rubber, when pushed in as described above, the protruding portion 13a is crushed and deformed inside the fitting recess 11b. Further, the bottom surface 13c of the tubed wire 13 is
Of the protruding portion 13a.
Returns to the original protruding state, and is fitted in the recess 11e of the fitting recess 11b, and fitted and fixed in the state shown in FIG. 1 (B). The pushing is performed over the entire length of the tubed wire 13, and the wire harness W / H is routed to the glass hatch 11. Thus, the wire harness W
The arrangement of / H can be easily performed because it is simply pushed into the fitting concave portion 11B of the glass hatch 11, and no misplacement or misalignment of the arrangement position can occur.

FIG. 8 shows a second embodiment of the present invention, in which a tubed wire 13 'is formed in the same manner as in the first embodiment so that its cross section is substantially rectangular. The tubed wire 13 'is provided with fitting projections 13d' from both sides of the bottom surface 13c 'at intervals in the full length direction. The interval is set to a size of 30 mm to 40 mm so that the tubed wire 13 'can be securely fixed.

A plurality of fitting recesses 11b 'are provided at intervals. The shape of the fitting recess 11b 'is
3 'has a shape corresponding to the bottom shape of the fitting projection 13d', and the interval between the fitting recesses 11b 'also corresponds to the interval between the fitting projections 13d'. In addition, fitting recess 1
The vertical and horizontal dimensions of 1b 'are set slightly shorter than the dimensions of the fitting projection 13d' so that the fitting projection 13d 'is press-fitted, and the depth dimension is set to the fitting projection 13d'. It is set to be equal to or deeper than the protruding length. When the fitting protrusion 13d 'has an elliptical bottom shape as described above, the fitting recess 11b' is also provided in a corresponding shape and position.

The arrangement of the tubed wire 13 ′ on the glass hatch 11 ′ is such that the fitting projection 13 d ′ is fitted into the corresponding fitting recess 11 b ′, and the bottom surface 13 c ′ of the tubed wire 13 ′ is placed in the glass hatch 11 ′. It is pushed in until it comes into contact with the inner surface 11a '. At this time, since the size of the fitting concave portion 11b 'is smaller than the size of the fitting protrusion 13d', the fitting is performed by press-fitting, and the fitting protrusion 13d 'is deformed so as to be contracted inside and fitted. Since it is in close contact with the inner wall of the recess 11b ', it is securely fixed. In the second embodiment as well, projections are provided on both sides of the fitting projection 13d ', and a recess is provided in the fitting recess 11b' so that the projection is housed in the recess at the time of fitting. It may be.
