Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a flat wiring mounting structure for a panel member, and more specifically, a flat plate of a panel member in which a flat wiring such as an FPC (flexible printed circuit) is interposed between the panel member and the interior material. Related to a wiring mounting structure.
[0002]
[Prior art]
In general, electrical components such as a switch, a window regulator, and a speaker are mounted on an automobile door, and wiring for supplying power to these electrical components is attached.
[0003]
This wiring is wired between the door panel and the interior material (door lining) installed in the door panel so that it is not visible from the viewpoint of appearance, etc., and the wiring is composed of FPC that requires less installation space. It has become so.
[0004]
As this type of conventional FPC, for example, the one shown in FIG. 3 is known. In FIG. 3, reference numeral 1 denotes an FPC. The FPC 1 has a flat plate shape in which a conductor 3 is attached in a flexible film substrate 2 in the extending direction of the film substrate 2. Further, an insertion hole 2a is formed at a predetermined position of the film substrate 2, and the FPC 1 is attached to the automobile door by inserting the bolt 4 into the insertion hole 2a.
[0005]
This mounting structure will be described with reference to FIG. In FIG. 4, reference numeral 5 denotes a door panel, and a bolt insertion hole 5 a is formed at a predetermined portion of the door panel 5. The bolt 4 can be screwed into the bolt insertion hole 5a, the insertion hole 2a of the film substrate 2 is aligned with the bolt insertion hole 5a, and the bolt 4 is screwed into the bolt insertion hole 4a through the insertion hole 2a. By doing so, the FPC 1 is fixed to the panel 5.
[0006]
The door panel 5 is provided with a door lining 6 as an interior material, and the FPC 1 is protected from the outside by the door lining 6 and improved in appearance. The FPC 1 may be attached to the bolt insertion hole 5a by a clip 6 shown in FIG.
[0007]
[Problems to be solved by the invention]
However, in such an FPC 1 mounting structure, since the insertion hole 2a is aligned with the bolt insertion hole 4a and the FPC 1 is attached to the door panel 5, the insertion hole 2a is positioned at the bolt insertion hole 4a. There was a problem that work was troublesome.
[0008]
Further, since it is necessary to attach the door lining 6 to the door panel 5 after the FPC 1 is attached to the door panel 5 in the automobile door assembly line, two assembling steps are required.
[0009]
Further, when removing the FPC from the door panel 5 for recycling, it is necessary to remove the FPC 1 from the door panel 5 after removing the door lining 6 from the door panel 5. The dismantling process has become necessary.
[0010]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a flat wiring attachment structure for a panel member that can easily attach the flat wiring to the panel member.
[0012]
[Means for Solving the Problems]
The present invention, in order to solve the above problems, the flexible film substrate over the extending direction of the film substrate is attached to the inner instrumentation material a flat wire attached conductor, the interior material In the flat wiring mounting structure of the panel member that is configured to hold the flat wiring between the interior material and the panel member by mounting on the panel member, an insertion hole is formed in a portion excluding the conductor of the film substrate to Rutotomoni, a plurality of engaging projections to be engaged into the opening hole panel member formed on the interior material provided, engaged to be engaged with a portion of the engaging protrusion into the through hole of the film substrate It is also used as a joint .
[0013]
In that case, the flat wiring can be attached to the interior material simply by engaging the insertion hole provided in the film substrate with the engaging projection provided in the interior material, improving the workability of the mounting work of the flat wiring. Can be made.
[0015]
In addition, since the flat wiring can be held between the panel member and the interior material at the same time that the interior material is attached to the panel member, the flat wiring is assembled to the panel member in a single process in the assembly line of the automobile door. Can be attached.
[0016]
Further, since the flat wiring can be removed from the panel member at the same time as the interior material is removed from the panel member, the flat wiring can be removed from the panel member in a single process during disassembly.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
1 and 2 are views showing an embodiment of a flat wiring mounting structure for a panel member according to the present invention, and show an example in which an FPC is used as a flat wiring and a door panel is used as a panel member.
[0019]
First, the configuration will be described. In FIG. 1, reference numeral 11 denotes an FPC (flat wiring). The FPC 11 has a conductor 13 attached to a flexible film substrate 12 in the extending direction of the film substrate 12, and an end portion of the conductor 13. Is attached with a connector 14 connected to electrical components (switches, window regulators, speakers, etc.) of the automobile door.
[0020]
Further, an insertion hole 12a is formed at the end in the width direction of the film substrate 12 excluding the conductor 13, and the FPC 11 is attached to a door lining as an interior material through the insertion hole 12.
[0021]
In FIGS. 1 and 2, reference numeral 15 denotes a door lining, and a plurality of engaging protrusions 16 that are partially engaged with the insertion holes 12 a of the film substrate 12 are provided on one side surface of the door lining 15. Further, the engagement protrusion 16 of the door lining 15 is engaged with an opening hole 17 a formed on one side surface of the door panel (panel member) 17, and the engagement protrusion 16 is engaged with the opening hole 17 a of the door panel 17. By joining, the door lining 15 is attached to the door panel 17. That is, in this embodiment, a part of the engagement protrusion 16 for attaching the door lining 15 to the door panel 17 also serves as an engagement protrusion for attaching the FPC 11.
[0022]
In the present embodiment having the above configuration, since the plurality of engaging protrusions 16 that are engaged with the insertion holes 12 a of the film substrate 12 are provided on the door lining 15, the FPC 11 can be easily attached to the door lining 15. It is possible to improve the workability of the FPC 11 attachment work.
[0023]
Further, the door lining 15 is provided with a plurality of engaging protrusions 16 that are engaged with the opening holes 17 a formed in the door panel 17, and a part of the engaging protrusions 16 is engaged with the insertion holes 12 a of the film substrate 12. Since the joint projection is also used, the FPC 11 can be held between the door panel 17 and the door lining 15 at the same time when the door lining 15 is attached to the door panel 17. For this reason, the FPC 11 can be assembled to the door panel 17 in a single process in the automobile door assembly line.
[0024]
Further, since the FPC 11 can be removed from the door panel 17 at the same time as the door lining 15 is removed from the door panel 17, the FPC 11 can be removed from the door panel 17 in a single process at the time of disassembly.
[0025]
In the present embodiment, the flat wiring is made of FPC, but is not limited to this, and may be made of FFC (flexible flat cable) or the like. Moreover, although the panel member is comprised from the door panel, if it is a panel member of the aspect to which not only this but an interior material is attached, it can apply to another panel member.
[0026]
【The invention's effect】
According to the present invention, the flat wiring can be attached to the interior material simply by engaging the insertion hole provided in the film substrate with the engaging protrusion provided in the interior material. Can be improved.
[0027]
In addition, since the flat wiring can be held between the panel member and the interior material at the same time that the interior material is attached to the panel member, the flat wiring is assembled to the panel member in a single process in the assembly line of the automobile door. Can be attached.
[0028]
Further, since the flat wiring can be removed from the panel member at the same time as the interior material is removed from the panel member, the flat wiring can be removed from the panel member in a single process during disassembly.
