Furthermore, the wire harness with wiring panel 10 is covered with a substantially rectangular flat door trim 36 from the indoor side (the upper side in the direction perpendicular to the paper surface in FIG. 1). In addition, in order to make an understanding easy, in FIG. 1, the door trim 36 is described by the virtual line.

Next, a wiring process of directly assembling a plurality of electric wires 24 to the surface 22 of the wiring panel 18 will be briefly described with reference to FIGS. The wiring panel 18 has a substantially rectangular flat plate shape, and wire fixing portions 26 are integrally provided at a plurality of locations on the surface 22 of the wiring panel 18 on which the plurality of wires 24 are arranged. The wire fixing portion 26 has a substantially bundling shape, as shown in FIG. More specifically, the wire fixing portion 26 is a substantially band-shaped band portion protruding on the surface 22 on one side (right side in FIG. 2) of the electric wire 24 in the width direction (left and right direction in FIG. 2). And a head-attached band portion 40 provided on the surface 22 of the other side (left side in FIG. 2) of the electric wire 24 in the width direction. The band portion 38 is capable of bending and deforming in the width direction of the electric wire 24, and on one surface 42 which is one side in the thickness direction of the band portion 38, a substantially sawtooth shaped locking projection 44 is formed of the band portion 38. Many are provided side by side in the longitudinal direction. The head-attached band 40 has a configuration in which the head 40 b is integrally formed at the projecting end of the substantially band-shaped band 40 a that is capable of bending and deforming in the width direction of the electric wire 24. . The head portion 40b is formed with a through hole 46 opening toward both sides in the thickness direction of the band portion 40a, and a locking piece 48 projecting inward is formed inside the through hole 46. It is provided. Then, in a state in which a plurality of electric wires 24 are disposed between the band portion 38 and the head portion attached band portion 40, the band portion 38 is curved in a ring shape and the tip end portion is a through hole 46 of the head portion attached band portion 40. The locking piece 48 of the through hole 46 is locked to the locking projection 44 of the band portion 38 by inserting it into the slot 38. Moreover, since the locking projection 44 of the band portion 38 is formed in a sawtooth shape, the locking action of the locking piece 48 on the locking projection 44 functions only in the direction in which the band portion 38 is pulled out from the through hole 46. Therefore, as shown in FIG. 2, the plurality of electric wires 24 can be non-releasingly tightened and fixed to the electric wire fixing portion 26 of the wiring panel 18. In order to facilitate understanding, in FIGS. 2 to 6, the electric wires 24 are described by imaginary lines.

According to the wire harness 10 with the wire lay panel according to this embodiment, the plurality of unbounded electric wires 24 arranged on the surface 22 of the wire lay panel 18 is the surface of the wire lay panel 18 Positioning and holding are performed by wire fixing portions 26 provided in a plurality of places 22 in a projecting manner. Moreover, since the wiring panel 18 has the fixing portion 20 to the vehicle, the wiring harness with wiring panel 10 of the present invention can be easily fixed to the door inner panel 14 constituting the vehicle. A wire harness consisting of a book electric wire 24 and

connectors

28 and 30 provided at its end can be provided as a wire harness wired at a predetermined position of the vehicle. With such a novel structure, first, the wiring diagram board required at the time of assembly of the conventional wire harness can be shared with the wiring panel 18 as a support for assembling the wire harness, thereby reducing the number of parts. Can. Further, since the plurality of unbonded electric wires 24 are positioned and held by the electric wire fixing portion 26 provided in a protruding manner on the wiring panel 18, the wiring wiring board is erected on the wiring diagram board required at the time of assembly of the conventional wire harness. It is possible to eliminate the need for the wired wiring jig. In addition, tape winding work of wire bundle, work of tying fixtures such as clips in appropriate place of wire bundle, work of removing such wire bundle from wiring jig and transporting it to vehicle production line, etc. Since a series of steps such as an operation of attaching to a support such as an inner panel of a door in a manufacturing line etc. can be eliminated, the reduction of the number of parts and the drastic simplification of the operation process can be achieved. In addition, in the conventional structure, it was necessary to precisely align the position of the fixture such as the clip attached to the wire bundle with the position of the mounting hole of the vehicle. Because the unit 26 is integrated, such adjustment can be eliminated.

In addition, since the wire fixing portion 26 is integrally provided to the wire laying panel 18, the operation of attaching a separate wire fixing portion to the wire laying panel 18 is not necessary, and thus, further work is performed. The process can be simplified and the number of parts can be reduced. Furthermore, since it is not necessary to provide a through hole or the like for fixing a separate wire fixing portion to the wiring panel 18, it is possible to improve waterproofness and vibration resistance. In addition, the wiring panel 18 houses and holds electric components such as the power window motor 32 and the speaker 34, and the connector 30 for supplying power and the like to the electric components is wired to the wiring panel 18 Since the electric components necessary for the door 12 can be supported by the wiring panel 18 and modularized. Therefore, it is possible to more easily arrange the wire harness including the electric component on the vehicle only by assembling the wiring panel 18 to the vehicle.

Although the embodiments of the present invention have been described above in detail, the present invention is not limited by these specific descriptions. For example, in the above embodiment, the wire fixing portion 26 is provided integrally with the wiring panel 18, but like the wire fixing portion 50 as a modification of the above embodiment shown in FIG. The portion 50 may be formed separately from the wiring panel 52, and the wiring panel 52 may be provided with a mounting portion 54 to which the separate wire fixing portion 50 is attached. Here, for example, a general-purpose binding band 56 is used as the wire fixing portion 50, while through holes 58 provided on both sides in the width direction (left and right direction in FIG. 3) of the wire 24 of the laying panel 52 are used as the attaching portion 54. It can be used. Thus, in a state where the band portion 60 of the binding band 56 is inserted into the through hole 58 and the plural electric wires 24 are disposed between the band portions 60, the band portion 60 is curved in a ring shape to bind the tip end portion. By inserting the plurality of electric wires 24 into the through holes 46 of the band 56 and tightening the plurality of electric wires 24, the plurality of electric wires 24 can be non-releasably tightened to the surface 22 of the wiring panel 52 for binding fixation. ing. As a result, even if a part of the wire fixing portion 50 is broken, it can be repaired only by replacing the general-purpose binding band 56 which constitutes the wire fixing portion 50, thereby improving the maintainability. Can. Moreover, the cost can be reduced by using the universal binding band 56. The wire fixing portion 50 according to the present embodiment may be formed separately from the wiring panel 52, and is not limited to the universal binding band 56.

Moreover, in the said embodiment shown in FIG. 2, although the electric wire fixing | fixed part 26 had a substantially bundling band shape, like the electric wire fixing | fixed part 62 as another aspect of the said embodiment shown in FIG. The portion 62 may have a substantially cylindrical shape extending in the extension direction of the electric wire 24 (in FIG. 4, the direction perpendicular to the paper surface). More specifically, the wire fixing portion 62 is formed with a substantially groove-shaped insertion hole 64 extending in the extension direction of the wire 24.

When the insertion of the electric wire 24 is completed, the electric wire fixing portion 62 elastically returns and the insertion hole 64 is narrowed, so that the electric wire 24 is prevented from being pulled out by the pair of retaining

projections

68, 68. Moreover, the plurality of electric wires 24 are fixedly accommodated and held inside the electric wire fixing portion 62 by an elastic restoring force directed inward of the electric wire fixing portion 62. In this embodiment, since the insertion work of the electric wire 24 can be performed only by the simple operation of pushing the plurality of electric wires 24 into the insertion hole 64 from above the electric wire fixing portion 62 in this manner, the operation can be simplified. Is possible.

Furthermore, in the other aspect of the embodiment shown in FIG. 4, the wire fixing portion 62 has a substantially cylindrical shape extending in the extension direction of the wire 24, but in the other aspect of the embodiment shown in FIG. Like the electric wire fixing portion 70 as a modification, even if the electric wire fixing portion 70 is formed to project in a substantially semicircular sectional shape which is upwardly convex in a cantilever shape from the surface 22 of the wiring panel 18 Good. More specifically, a gap β is formed between the projecting end of the wire fixing portion 70 and the surface 22 of the wiring panel 18. The outer surface of the protruding end of the wire fixing portion 70 is provided with a substantially flat guide projection 66 which protrudes upward and diagonally outward, while the inner surface of the protruding end is slightly inclined and inward downward. A substantially flat retaining projection 68 is provided to project toward the end. In addition, on the surface 22 of the wired panel 18 facing the projecting end of the wire fixing portion 70, a retaining projection 72 projecting in a substantially mountain-like cross sectional shape is provided. Also in the present embodiment, the wire 24 can be inserted into the wire fixing portion 70 by pushing the plurality of wires 24 into the gap β from the side (left in FIG. 5) of the wire fixing portion 70. On the other hand, after the wire 24 is inserted, the retaining

projections

68 and 72 prevent the wire 24 from coming out to the outside. Moreover, the plurality of electric wires 24 are fixedly accommodated and held inside the electric wire fixing portion 70 by the elastic restoring force directed inward of the electric wire fixing portion 70. Also in the present embodiment, since the wire 24 can be inserted by the simple operation of pushing the plurality of wires 24 into the gap β from the side of the wire fixing portion 70 as described above, the operation can be simplified. It has become possible.

In addition, in the other aspect of the above embodiment shown in FIG. 4, the wire fixing portion 62 is integrally provided to the wiring panel 18, but as another aspect of the above embodiment shown in FIG. 6. Like the wire fixing portion 74, the wire fixing member 76 is formed separately from the wiring panel 78, and the wiring panel 78 is a substantially L-shaped attachment portion to which the separate wire fixing member 76 is attached. A hook portion 80 having a cross-sectional shape may be provided. Here, on the bottom surface of the wire fixing member 76, an engaged portion 82 having a substantially U-shaped cross-sectional shape that is fixedly engaged with the hook portion 80 by a fixing mechanism (not shown) is provided.
