Description

Wire Harness

The present invention relates to a wire harness, and particularly to a wire harness provided with an exterior material mounted on a vehicle or the like.

In many cases, a wire harness mounted on a vehicle such as an automobile is equipped with a corrugated tube capable of protecting an electric wire group or an exterior material such as a protector capable of protecting the electric wire group and restricting a routing route. In addition, the exterior material is required to be lightweight and rigid enough to accurately regulate the path of the wire harness, and may be required to bend or extend or contract depending on the routing path.

As a wire harness equipped with a conventional exterior material, for example, a non-woven fabric is formed into a three-dimensional shape by hot pressing, and the non-woven fabric's basis weight (weight per unit volume) is made different, or unevenness in the radial direction is partially formed By doing so, what forms the path | route regulation and bending | flexion allowance part from which bending rigidity differs relatively is known (for example, refer patent document 1).

In addition, it is known that a non-woven fabric is formed into a flat bellows shape by hot pressing to constitute an exterior material having improved stretchability and bendability (for example, see Patent Document 2).

JP 2012-253866 A JP 2012-213300 A

However, the conventional wire harness as described above has a problem that the manufacturing cost of the exterior material is high, and the manufacturing cost of the wire harness using the exterior material is high.

Also, when the nonwoven fabric absorbs water, it is difficult for the water to be drained, so that there is a problem that the exterior material cannot be disposed in the wet area.

Furthermore, when the route regulation section of the wire harness is long and the section of the nonwoven fabric having a large basis weight is long, the weight reduction is insufficient.

Therefore, the present invention can easily achieve both a path regulation function and an expansion / contraction / bending allowance function, and is provided with a lightweight and low-cost exterior material that is excellent in drainage even if it is placed in a wet area. The purpose is to provide a harness.

In order to achieve the above object, the wire harness according to the present invention is a wire harness including an exterior material that is sheathed in a specific section so as to surround the specific section in the length direction of the electric wire group, and the exterior material is a predetermined one. By a plastic corrugated cardboard material having a pair of liner sheet portions facing each other in parallel with a gap layer therebetween, and a plurality of rib-like connection portions that divide the gap layer into a plurality while integrally joining both liner sheet portions A cylindrical body formed by bending the plastic corrugated board material into a polygonal cylindrical shape in which the connecting portion extends in the circumferential direction, and the liner is formed in a partial region in the axial direction of the exterior material. A part of the sheet portion is partially cut into a slit shape between the adjacent connecting portions, and at least one of the outer peripheral surface and the inner peripheral surface of the cylindrical body has a partially corrugated longitudinal sectional shape. It is those who are.

With this configuration, according to the present invention, the liner sheet portion is formed such that at least one of the outer peripheral surface and the inner peripheral surface of the partial region in the axial direction of the exterior material partially has a corrugated longitudinal sectional shape. The part is cut off, and it becomes low bending rigidity. On the other hand, in the remaining portion in the axial direction, the pair of liner sheet portions of the exterior material are continuous in the axial direction and are connected to each other by a rib-like connecting portion, so that high bending rigidity is achieved. Accordingly, it is possible to provide a path regulating function to the remaining axial portion while providing a function of allowing expansion / contraction and bending to a partial region of the exterior material in the axial direction. In addition, since a plastic corrugated cardboard material is used, it does not absorb water, and even if it is placed in the water-receiving area, it has excellent drainage properties, and it becomes a low-cost exterior material.

In the wire harness of the present invention, the rib-like connecting portions are respectively cut at a plurality of locations in the circumferential direction corresponding to the corners of the polygonal cylindrical shape, while the axial portions in the partial region are The liner sheet portion on the inner peripheral surface side or the outer peripheral surface side may be continuous in the circumferential direction.

In this manner, a polygonal cylindrical body can be easily formed from a plate-like plastic corrugated cardboard material, and its outer peripheral surface and / or inner peripheral surface can be easily formed in a partial region in the axial direction of the exterior material. Can be processed into a corrugated longitudinal section.

In the wire harness of the present invention, a part of the liner sheet portion on the outer peripheral surface side and a part of the liner sheet portion on the inner peripheral surface side in a partial region in the axial direction of the exterior material, Alternately, the entire circumference may be excised.

In this case, a partial region in the axial direction of the exterior material has a shape similar to a bellows, and good flexibility and stretchability can be obtained.

According to the present invention, a wire having a lightweight and low-cost exterior material that can easily achieve both a path regulation function and an expansion / contraction / bending permission function, and has excellent drainage performance even when placed in a water-filled area. A harness can be provided.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

(One embodiment)
1 to 5 show a wire harness according to an embodiment of the present invention.

The wire harness of the present embodiment is routed, for example, near a bent portion of a car body panel of an automobile or between a car body panel and a movable part in which electrical components are incorporated.

As shown in FIG. 1, the wire harness 10 of this embodiment includes a bundle of electric wires 11 composed of a plurality of electric wires, and an electric wire group in a specific exterior section in the length direction along the routing route of the electric wires 11. 11 and an exterior material 12 that is exteriorized so as to surround 11.

Although not shown in detail, the electric wire group 11 is used for, for example, an electric actuator or sensor mounted on a vehicle or other equipment, and includes any one of a power supply line, a signal line, a ground line, and the like. It is comprised by the some electric wire. Each electric wire of the electric wire group 11 includes, for example, a stranded wire conductor having good conductivity and an electrically insulating coating resin that concentrically surrounds the conductor.

As shown in FIG. 2A to FIG. 2C and FIG. 3, the exterior material 12 includes a pair of liner sheet portions 21 and 22 and a plurality of rib-like shapes that connect the liner sheet portions 21 and 22 in parallel with a predetermined gap therebetween. Are formed by a plate-like plastic corrugated cardboard material 20 having a connecting portion 23.

The plastic corrugated cardboard material 20 is formed of a plate-like body similar to corrugated paper having a flute and a liner sheet, and is also called corrugated plastic.

The pair of liner sheet portions 21 and 22 are plastic sheets facing in parallel across a certain gap layer 24, for example, a sheet made of polypropylene resin (PP) having a low specific gravity and excellent heat resistance and mechanical strength. They have the same thickness and material.

The plurality of rib-like connecting portions 23 are a plurality of substantially parallel wall portions that divide the gap layer 24 into a plurality of strip-like spaces 24a while integrally connecting the liner sheet portions 21 and 22, and each liner sheet portion. 21 and 22 are substantially the same thickness and the same material. That is, the plurality of connecting portions 23 are also made of plastic, for example, polypropylene resin (PP).

This plastic corrugated cardboard material 20 is uniformly extruded so as to have a ladder-like cross-sectional shape such as a path regulation region Z1 shown in cross section in FIG. 2C, and then cut into a predetermined material contour shape. Further, secondary processing is performed in which partial cutting or excision is performed in the thickness direction.

The plurality of rib-like connecting portions 23 extend in parallel with each other. As shown in FIGS. 2B and 2C, not only the extending direction of these connecting portions 23 but also the cross-sections of the plurality of connecting portions 23 They are completely parallel.

However, the cross sections of the plurality of rib-like connecting portions 23 may not be parallel. That is, the cross sections of each pair of adjacent connecting portions 23 may be inclined in opposite directions, and the cross sections of the plurality of connecting portions 23 may alternately reverse the inclination directions. Specifically, each pair of adjacent connecting portions 23 inclines in a substantially “C” shape so that the cross section of each of the pair of connecting portions 23 approaches on either side of the liner sheet portions 21 and 22 and separates on the other side. Thus, the plurality of connecting portions 23 may be configured so as to have a corrugated cross-sectional shape close to the flute of the cardboard as a whole.

As shown in FIGS. 1 and 3, the exterior material 12 is a cylindrical body obtained by bending a plastic corrugated cardboard material 20 into a polygonal cylindrical shape with a plurality of rib-like connecting portions 23 extending in the circumferential direction. The polygonal cross-sectional shape forming the internal space 12c, for example, a quadrangular (rectangular or square) cross-sectional shape.

Further, in a partial region in the axial direction of the outer casing 12 having a polygonal cylindrical shape, for example, the expansion / contraction and bending allowable region Z2 shown in cross section in FIG. 2C, the liner sheet 21 on the outer peripheral side and / or the liner on the inner peripheral side. The sheet portion 22 is partially cut out in a slit shape between the adjacent rib-shaped connecting portions 23. Then, at least one of the outer peripheral surface 12a and the inner peripheral surface 12b of the exterior material 12 partially has a rectangular wave-shaped (corrugated) longitudinal cross-sectional shape.

Specifically, as shown in FIGS. 3 to 5, the parallel rib-shaped connecting portion 23 extends in the circumferential direction corresponding to the polygonal cylindrical corner of the exterior material 12 over substantially the entire axial direction of the exterior material 12. Are cut at a plurality of locations.

Further, between each pair of connecting portions 23 adjacent in the expansion and contraction and bending allowance region Z2, either the liner sheet portion 21 on the outer peripheral surface 12a side or the liner sheet portion 22 on the inner peripheral surface 12b side is partially The other side of the liner sheet portion 21 on the outer peripheral surface 12a side or the liner sheet portion 22 on the inner peripheral surface 12b side is continuously formed in the circumferential direction.

And in each surface corresponding to each side of the polygonal cross section of the exterior material 12, at least one of the outer peripheral surface 12a and the inner peripheral surface 12b is partially corrugated in longitudinal cross-sectional shape.

Therefore, in the part in which one (one) of the outer peripheral surface 12a and the inner peripheral surface 12b in the expansion / contraction and bending permissible region Z2 of the exterior material 12 partially has a corrugated longitudinal cross-sectional shape, the other (the other one) In this case, the outer peripheral surface 12a and the inner peripheral surface 12b partially have a corrugated longitudinal sectional shape in the entire expansion / contraction and bending allowable region Z2. explain.

In a partial region in the axial direction of the exterior member 12 corresponding to the expansion / contraction and bending allowable region Z2, both the outer peripheral surface 12a and the inner peripheral surface 12b partially have a corrugated longitudinal sectional shape, and the outer peripheral surface The portion where the liner sheet portion 21 on the 12a side is cut out in a slit shape and the portion where the liner sheet portion 21 on the outer peripheral surface 12a side is left in the shape of a band supported by a pair of connecting portions 23 alternately Is arranged.

Further, in the expansion / contraction and bending allowable region Z2, the liner sheet portion 22 on the inner peripheral surface 12b side is surrounded by an axial section in which the liner sheet portion 21 on the outer peripheral surface 12a side is cut into a slit extending in the circumferential direction. A pair of connecting portions 23 that are formed continuously in the direction and are adjacent to each other at both end portions thereof are arranged so as to be integrally coupled.

Then, a part of the liner sheet portion 21 on the outer peripheral surface 12a side and a part of the liner sheet portion 22 on the inner peripheral surface 12b side in the expansion and contraction and bending permissible region Z2 are alternately cut around the entire circumference, as a whole. Each surface corresponding to each side of the polygonal cross section of the exterior material 12 forms a rectangular wave-shaped vertical cross section. Therefore, in the stretchable / bendable region Z2, the exterior material 12 has a shape similar to an accordion, and good flexibility and stretchability are obtained.

The exterior material 12 further includes a thin wall region Z3 having a relatively low bending rigidity adjacent to the path regulation region Z1 or the expansion / contraction and bending allowable region Z2.

In this thin region Z3, either the liner sheet portion 21 on the outer peripheral surface 12a side or the liner sheet portion 22 on the inner peripheral surface 12b side, and the connecting portion 23 are cut off, and the outer peripheral surface 12a side or inner peripheral surface is cut. The thin region Z3 is configured by only one of the liner sheet portions 21 and 22 on the surface 12b side, for example, only the liner sheet portion 22 on the inner peripheral surface 12b side.

In the above description, slit-shaped excision is performed by excising the liner sheet portion 21 on the outer peripheral surface 12a side or the liner sheet portion 22 on the inner peripheral surface 12b side located between a pair of adjacent rib-shaped connecting portions 23. Including the case where the slit sheet width is narrow and the liner sheet portion 21 on the outer peripheral surface 12a side or the liner sheet portion 22 on the inner peripheral surface 12b side remains between a pair of adjacent rib-shaped connecting portions 23, It is good that they do not interfere with each other.

Further, as shown in FIG. 2A, the plastic corrugated board material 20 is provided with an adhesive margin portion 25 for connecting both ends bent into a cylindrical shape during the secondary processing. As shown by phantom lines, the cut portion may be formed to extend to the bonding margin portion 25 at the time of the above-described slit-shaped cut.

Next, the operation will be described.

In the wire harness of the present embodiment configured as described above, the corrugated longitudinal section of the outer peripheral surface 12a and / or the inner peripheral surface 12b is formed from a plate-like plastic corrugated cardboard material 20 in a partial region in the axial direction. The polygonal cylindrical outer packaging material 12 can be easily produced.

In the expansion / contraction and bending allowable region Z2 of the exterior member 12, one of the liner sheet portions 21 and 22 is formed such that at least one of the outer peripheral surface 12a and the inner peripheral surface 12b partially has a corrugated longitudinal sectional shape. Since the part is cut off, it has low bending rigidity.

On the other hand, in the path regulation region Z1 that is the remaining portion in the axial direction, the pair of liner sheet portions 21 and 22 of the exterior material 12 are connected to each other by a plurality of rib-like connecting portions 23 that are continuous in parallel with each other in the axial direction. Therefore, it has high bending rigidity.

Moreover, since the liner sheet | seat part 22 of the single side | surface side of the cladding | exterior_material 12 has comprised the rectangular cylinder shape which continues in an axial direction and the circumferential direction, the thin area | region Z3 is from the expansion-contraction and bending | flexion tolerance area | region Z2 which makes the longitudinal cross-sectional shape of a waveform. Has a relatively high rigidity, and has a relatively low rigidity as compared with the path regulation region Z1.

Furthermore, the length of the path regulation region Z1, the length of the expansion / contraction and bending allowable region Z2 and the length of the thin region Z3 in the axial direction of the exterior material 12 can be appropriately set according to the range of the secondary processing. Therefore, in a partial section in the axial direction of the exterior member 12 where expansion and contraction is required, the expansion and contraction and bending allowance area Z2 is allowed to exhibit the expansion and contraction and bending allowable functions, and the path regulation of the wire group 11 is required. In this section, the required route restriction function can be exhibited by the route restriction region Z1.

In addition, the outer diameter or the inner diameter is partially changed by the thin-walled area Z3, slight bending or bending is absorbed in the middle of the path regulation section, or between the path regulation area Z1 and the expansion / contraction and bending allowance area Z2. An appropriate rigidity adjustment section can be set.

Further, since the outer packaging material 12 uses a plastic corrugated cardboard material, it does not absorb water and has excellent drainage even if it is disposed in a wet area. Furthermore, since the plastic corrugated cardboard material 20 can be produced from general plastic corrugated cardboard frequently used for returnable boxes, floor-curing sheets, etc., the packaging material 12 can be manufactured at low cost.

As described above, in the present embodiment, it is only necessary to perform the secondary process of cutting a part of the liner sheet portions 21 and 22 into a slit shape on at least one side of the outer peripheral surface 12a and the inner peripheral surface 12b of the exterior material 12. The expansion / contraction and bending allowance area Z2 can be formed in a part of the axial direction, and the path restriction area Z1 can be formed in another section. Therefore, the path regulation function required in the exterior section of the exterior material 12 can be easily made compatible with the function of allowing expansion and contraction and bending. Moreover, since the packaging material 12 is formed using the plastic corrugated cardboard material 20, the wire harness 10 provided with the lightweight and low-cost packaging material 12 having excellent drainage even when arranged in the water-receiving area can be provided.
