Abstract

PROBLEM TO BE SOLVED: To perform wiring inside a back door without installing any dedicated hole in an inner panel of the back door or any bent part dedicated to a joint part between an outer panel and the inner panel by passing a wire harness through a hole bored in the outer panel. SOLUTION: A back door of a vehicle is constructed of an outer panel 3 and an inner panel 4, while a window glass 5 is installed to the outer panel 3 via an adhesive 6. In the window glass 5, a heating wire is printed on the inside of the glass 5 for defrosting on the glass 5. In the end part of the heating wire, a plate type terminal 7a is arranged, while a wire harness 6 provided with a connector at the tip is connected to the terminal 7a so as to supply electric power to the heating wire. The wire harness 8 whose tip is fixed to the terminal 7a passes through a clearance between the outer panel 3 and the window glass 5 so as to be connected to the back door inside via a hole 9 bored in the outer panel 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating wire printed on a window glass adhered to a vehicle body and a wiring structure used for an antenna for an acoustic device.

[0002]

2. Description of the Related Art A wiring structure of a hot wire printed on a window glass for a vehicle is shown in FIGS.
No. 119,046, Japanese Utility Model Laid-Open No. 61-179149, and Japanese Utility Model Publication No. 3-8332. FIG.
FIG. 8 shows an outer panel and an inner panel 15 (not shown).
On the outer panel side of the back door 16 comprising a back door window glass 18 having a rear defogger heating wire 17 printed on the surface thereof, is fixed using an adhesive (not shown). A wire harness 19 is connected to the heating wire 17 to supply power to the heating wire 17. By the way, the wire harness 19 extends from the inner panel 15 toward the window glass 18,
The heating wire 17 printed on the window glass 18 was connected. However, since the wire harness 19 extends from the inner panel 15 side of the back door 16 to the heating wire 17, this section is exposed and the wire harness 19 is exposed from the vehicle interior. How to reduce the exposed portion has been an important issue for improving the appearance.

In FIG. 7, the wire harness 19 connected to the heating wire 17 is routed along the inner panel 15, and the wire harness 19 is connected to the trim 20 fixed to the inner panel 15 from the boundary between the inner panel 15 and the trim 20 fixed to the inner panel. It is wired inside the back door 16. Even with this wiring method, the wire harness 19 is exposed on the inner panel 15 and can be seen from the passenger compartment, which is not preferable in appearance.
In FIG. 8, the wire harness 19 connected to the heating wire 17 is provided in the inner panel 15, passes through a hole in which the grommet 21 is fitted, and is wired inside the back door 16. However, there is a hole in the inner panel,
Since a special grommet is required, the cost increases. Further, a seating surface for providing a hole is required for the inner panel, which increases restrictions on manufacturing the inner panel, which is not preferable in design. In FIG. 9, a wire harness 22 connected to a hot wire (not shown) passes through a space 25 formed by bending a part of a joint surface between an outer panel 23 and an inner panel 24 and passes through a back door 26.
It is wired to. However, since a dedicated bent portion must be provided on the outer panel or the inner panel to form the space 25, both the cost and the number of manufacturing steps increase.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a dedicated hole is provided in an inner panel of a back door for a wire harness connected to an electric wire printed on a window glass, or a joint between an outer panel and an inner panel is provided. Provided is a wiring structure of a wire harness that can be wired in a back door without providing a dedicated bent portion in the portion.

[0005]

In order to achieve the above object, the present invention is characterized in that a wire harness is passed through a hole formed in an outer panel.

[0006]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a part of a rear portion of a vehicle using the present invention, FIG. 2 is a perspective view of an entire back door using the present invention, and FIG. 4 is an enlarged front view (a part originally hidden by the glass ceramic print is also indicated by a solid line), FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 3, and FIG. 6 is a perspective view showing a part of the back door in an enlarged manner, as viewed from the vehicle interior. FIG. 6 is a view showing only the outer panel of FIG.

The back door 2 of the vehicle 1 has an outer panel 3
And an inner panel 4 and a window glass 5
Are attached to the outer panel 3 by an adhesive 6. A glass ceramic print 5a is applied to an arbitrary section from the outer periphery of the window glass 5. The ceramic printed portion cannot be seen through, so that anything indoors from the window glass 5 cannot be seen from the outside. A heat wire 7 is printed on the inside of the window glass 5 in order to remove the fogging of the glass 5. A plate-like terminal 7 a is provided at an end of the heating wire 7, and a wire harness 8 having a connector at the end is provided.
It is coupled to the terminal 7a to supply power to the heating wire 7. The wire harness 8, the tip of which is fixed to the terminal 7 a, is connected to the outer panel 3 and the window glass 5.
, Through the hole 9 formed in the outer panel 3 and into the back door 2.

The hole 9 is located closer to the center of the outer panel than the place where the adhesive 6 is applied, and has a stepped shape. The holes 9a, 9b, and 9c are arranged in the order of smaller area. (See FIG. 6). A clip 10 is provided so as to abut against a partition 9d that separates the spaces 9a and 9b of the hole 9. The wire harness 8 passes through the space 9 a above the hole 9 while being in contact with the clip 10. The clip 10 has a function to be used together with the clip 11 provided on the window glass for positioning and temporarily holding the window glass 5 at the time of bonding to the back door 2. The position and the shape of the hole 9 are the same as those of the ceramic print 5a.
Can be freely selected depending on the position of the terminal 7a of the heating wire 7 as long as the position is not visible from the outside. In the above-described embodiment, the wiring structure for hot wire printed on the window glass 4 provided on the back door 2 has been described. However, the structure of the present invention is printed on the quarter window glass 13 provided on the side body 12 of the vehicle. It can also be used for a wiring structure connected to the acoustic device antenna 14.

[0009]

According to the present invention, the wiring harness and the wiring hole are not visible from the outside due to the ceramic printed portion of the window glass, so that the appearance can be improved. Most of the parts exposed outside the back door of the wire harness are
Since the gap between the outer panel and the window glass is wired, it is almost invisible even from the vehicle interior, so that the marketability is improved. In the hole through which the wire harness passes, a hole that has been drilled can be used to fix a clip for temporarily holding the window glass, and a new hole needs to be drilled or a special clip is provided Since there is no need, the rigidity of the vehicle body is not reduced, and it is possible to contribute to a reduction in the number of manufacturing steps and the number of parts. By clip
Since the position of the wire harness can be regulated, the window glass and the wire harness do not interfere with each other. Since the hole through which the wire harness passes is located closer to the center of the outer panel than the position where the window glass is bonded and fixed, there is no problem in the sealing performance.
