Japanese Unexamined Patent Publication No. 2010-51042

In the above prior art, in order to route the wire harness while restricting the route, a plurality of types of exterior members such as a corrugated tube and a protector are required. This wire harness requires a plurality of corrugated tubes. Accordingly, since the number of parts increases, there are problems such as an increase in cost, man-hours, and complicated parts management.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a wire harness capable of reducing cost and man-hours and facilitating component management.

In order to achieve the above object, a wire harness according to the present invention is characterized by the following (1) to (5).
(1) In a wire harness including a conductive path and a tubular-shaped exterior member that covers the conductive path, the exterior member includes a flexible low-rigidity portion that is continuous in the extending direction of the conductive path, and And a high-rigidity part having higher rigidity than the low-rigidity part.

(2) In the wire harness described in the above (1), the conductive path and the exterior member are formed to have a length that passes under the vehicle floor and extends across the vehicle floor.
The high-rigidity part is formed according to the shape of the mounting position under the vehicle floor.

(3) In the wire harness described in (2) above, the high-rigidity portion has two parallel walls arranged on the side facing the vehicle floor and the side facing the ground.

(4) In the wire harness described in (3) above, the high-rigidity portion has two symmetrical support walls that support the two walls.

(5) In the wire harness described in (4) above, the two support walls are formed in a curved shape that swells away from each other.

(6) In the wire harness described in (4) or (5) above, the two walls are deformed so that the outer surface of the wall is deformed outward and the inner surface of the wall is also tracked along with the deformation of the outer wall. It has the deformation part which becomes.

According to the above (1), with respect to the exterior member, since the one having a structure in which the low-rigidity portion and the high-rigidity portion are continuous in the extending direction of the conductive path is adopted, a plurality of types of conventional exterior members are used. In addition, it is not necessary to use a plurality of, for example, one of a plurality of types, so that the number of parts can be minimized. Therefore, according to this invention, there exists an effect that reduction of cost and a man-hour can be aimed at by employ | adopting the exterior member of the said structure. In addition, there is an effect that parts management can be facilitated.

According to the above (2), in addition to the effect of (1), the following effect is also achieved. That is, the wire harness of the present invention is a long one that passes under the vehicle floor, and the exterior member used for the long wire harness has a structure in which a high-rigidity portion is arranged in accordance with the position under the vehicle floor. Unnecessary bending can be suppressed at the time of wiring harness wiring operation (attachment operation). Therefore, there is an effect that workability can be improved.

According to the above (3), in addition to the effect of (2), the following effect is also achieved. That is, since the high-rigidity portion has two parallel walls arranged on the side facing the vehicle floor and the side facing the ground, such an exterior member is, for example, an exterior member having a circular cross section. Compared to the structure, the wire harness can be kept away from the ground. In other words, the height can be reduced. Therefore, there is an effect that it is difficult to be influenced by the ground side. In addition, the function and reliability of the wire harness can be maintained.

According to the above (4), in addition to the effect of (3), the following effect is also achieved. That is, since the high-rigidity part has two support walls, these can be supported in a state in which the arrangement of the two walls is maintained. Further, since the two support walls are symmetric, the two walls can be supported in a stable state. Therefore, it is possible to obtain a highly rigid portion having a structure that is not easily damaged. In addition, there is an effect that the high rigidity portion can be given sufficient strength.

According to the above (5), in addition to the effect of (4), the following effect is also achieved. In other words, the two symmetrical support wall shapes are curved shapes that bulge outward, so that when the exterior member is made of resin, for example, the mold release property is less than the shape that does not bulge (shape perpendicular to the two walls). Can be improved. Therefore, there is an effect that the exterior member can be manufactured with good manufacturability.

According to (6) above, in addition to the effects of (4) or (5), the following effects are also achieved. That is, since two parallel walls arranged on the side facing the vehicle floor and the side facing the ground have a deformed portion that deforms the outer surface of the wall outward, it is possible to give strength to the deformed portion. it can. Therefore, it is possible to obtain a highly rigid portion having a structure that is not easily damaged. In addition, there is an effect that the high rigidity portion can be given sufficient strength.

In addition, since the deformed portion has a shape that also follows the wall inner surface as it deforms outward, when the exterior member is made of resin, for example, the amount of resin should be reduced compared to a shape that does not follow the wall inner surface side. Can do. If the amount of resin can be reduced in this way, cooling during molding can be accelerated. Therefore, it is possible to increase the molding speed and to produce an exterior member with good manufacturability.

Furthermore, the surface area of the deformed portion can be increased by the above deformation. Therefore, there is an effect that the cooling at the time of molding can be accelerated, and the heat dissipation at the time of use can be enhanced.

The wire harness includes one or a plurality of conductive paths and an exterior member that accommodates and protects the conductive paths. The wire harness is long and passes under the vehicle floor, and the exterior member is formed in a shape in which a low-rigidity portion and a high-rigidity portion are continuous in the extending direction of the conductive path. The exterior member is formed and formed with a highly rigid portion in accordance with the position under the vehicle floor, and two parallel walls and two symmetrical support walls are formed in the highly rigid portion.

Hereinafter, Example 1 will be described with reference to the drawings. FIG. 1 is a schematic diagram illustrating a wiring state of the wire harness according to the first embodiment of the present invention. 2 is a perspective view of the wire harness, and FIG. 3 is a cross-sectional view taken along line AA of FIG.

In the present embodiment, the present invention is adopted for a wire harness routed in a hybrid vehicle (which may be an electric vehicle or a general vehicle).

In FIG. 1, a hybrid vehicle 1 is a vehicle that mixes and drives two powers of an engine 2 and a motor unit 3, and the motor unit 3 receives power from a battery 5 (battery pack) via an inverter unit 4. Is supplied. The engine 2, the motor unit 3, and the inverter unit 4 are mounted in the engine room 6 near the front wheels in this embodiment. Further, the battery 5 is mounted on the rear part 7 near the rear wheel. Note that the battery 5 may be mounted in an automobile room existing behind the engine room 6.

The motor unit 3 and the inverter unit 4 are connected by a high-voltage wire harness 8. The battery 5 and the inverter unit 4 are also connected by a high-voltage wire harness 9. In the wire harness 9, the intermediate portion 10 is routed along the vehicle underfloor 11, and is routed substantially parallel along the vehicle underfloor 11. The vehicle underfloor 11 is a known body and a so-called panel member, and a through hole is formed at a predetermined position. The wire harness 9 is inserted into the through hole in a watertight manner.

The wire harness 9 and the battery 5 are connected via a junction block 12 provided in the battery 5. The rear end 13 of the wire harness 9 is electrically connected to the junction block 12 by a known method. The front end 14 side of the wire harness 9 is electrically connected to the inverter unit 4 by a known method.

The motor unit 3 functions as a motor and a generator. The inverter unit 4 functions as an inverter and a converter. The motor unit 3 is formed as a motor assembly including a shield case. The inverter unit 4 is also formed as an inverter assembly including a shield case. The battery 5 is of Ni-MH type or Li-ion type and is modularized. It is assumed that the hybrid vehicle 1 can use a power storage device such as a capacitor instead of the battery 5. The battery 5 is not particularly limited as long as it can be used for the hybrid vehicle 1 and the electric vehicle.

In FIG. 2, the wire harness 9 includes a high-voltage conductive path 15 (conductive path), an exterior member 16 that accommodates and protects the high-voltage conductive path 15, a shield connector (not shown) provided at the end of the high-voltage conductive path 15, A plurality of clamps (not shown) attached to the outer surface of the exterior member 16 and grommets are configured.

The wire harness 9 may be configured and structured so that the low voltage conductive path and the high voltage conductive path 15 are accommodated and protected by the exterior member 16.

2 and 3, the high-voltage conductive path 15 includes two high-voltage circuits 17, a shield member 18 that covers the two high-voltage circuits 17, and a sheath 19 that is provided outside the shield member 18. (Assumed to be an example).

Here, the high voltage circuit 17 is a known high voltage electric wire, and includes a conductor 20 and an insulator 21 covering the conductor 20. The high voltage circuit 17 is formed to have a length necessary for electrical connection. The high voltage circuit 17 is formed in a long shape because the wire harness 9 electrically connects the inverter unit 4 and the battery 5 (junction block 12) (see FIG. 1).

The conductor 20 is made of copper, copper alloy, aluminum, or aluminum alloy. The conductor 20 has a conductor structure in which strands are twisted or a bar-like conductor structure having a rectangular or round cross section (for example, a conductor structure having a flat single core or a single round core, in which case the wire itself Can also be any of those having a rod shape. An insulator 21 made of an insulating resin material is extruded on the outer surface of the conductor 20.

In addition, although the structure of a well-known high voltage electric wire is employ | adopted as a high voltage circuit 17 in a present Example, it shall not be this limitation. That is, a known bus bar with an insulator provided as a high voltage circuit may be employed.

The shield member 18 is a member for electromagnetic shielding (shield member for electromagnetic waves) that collectively covers the two high-voltage circuits 17, and a known braid formed by knitting a large number of strands into a cylindrical shape is adopted. The The shield member 18 is formed to have substantially the same length as the entire length of the two high-voltage circuits 17. The end of the shield member 18 is connected to a shield case or the like (not shown) of the inverter unit 4 (see FIG. 1) via the shield connector (not shown).

The shield member 18 may adopt, for example, a conductive metal foil or a member including this metal foil as long as it can take countermeasures against electromagnetic waves.

The sheath 19 is formed by extruding an insulating resin material with a predetermined thickness to the outside of the shield member 18, and is disposed at a position to be the outermost layer of the high-voltage conductive path 15. In the present embodiment, the sheath 19 is included in the conductive path configuration, but the shield member 18 may be disposed in the outermost layer without providing the sheath 19.

In addition, a known shielded electric wire may be used instead of the high voltage conductive path 15. Even in this case, the number is one or more. Alternatively, a high-voltage coaxial composite conductive path (not shown) or the like configured to have a single plus circuit and a minus circuit coaxially, or to have three or more circuits coaxially may be used.

2 and 3, the exterior member 16 is a resin tube covering the high-voltage conductive path 15 and has a shape necessary for insertion and accommodation of the high-voltage conductive path 15 and a thickness necessary for protection. Formed. The exterior member 16 is formed as an elongate member passing through the vehicle underfloor 11 (see FIG. 1) and straddling the front and rear of the vehicle underfloor 11. The exterior member 16 is not limited to resin and may be made of metal as long as it has a low rigidity portion 24 and a high rigidity portion 25 described later.

The exterior member 16 has an outer surface 22 and an inner surface 23. The exterior member 16 has a low-rigidity portion 24 that can be bent and a high-rigidity portion 25 that is higher in rigidity than the low-rigidity portion 24 and is formed in a shape as shown in FIG. Specifically, the low-rigidity portion 24 and the high-rigidity portion 25 are formed in a shape that is continuous in the extending direction of the high-voltage conductive path 15. The exterior member 16 has a plurality of low-rigidity portions 24 and high-rigidity portions 25, respectively, and these are alternately arranged to be continuously formed. The exterior member 16 is resin-molded so that the low-rigidity portion 24 and the high-rigidity portion 25 are linear without bending the low-rigidity portion 24.

The low-rigidity portion 24 is arranged and formed according to the vehicle mounting shape (the shape of the wire harness wiring destination. The shape to be fixed). Specifically, the low-rigidity portion 24 is arranged in accordance with a section that needs to be bent. The low rigidity portion 24 is formed to have a length necessary for bending. In addition, the low-rigidity portion 24 of this embodiment is formed in a substantially rectangular cross section. The low-rigidity portion 24 is formed so as to be able to be bent at a desired angle at the time of packaging, transportation, and route routing to the vehicle (at the time of attachment) after the manufacture of the wire harness 9 ( (Not shown).

The low-rigidity portion 24 can be bent to have a desired bent shape and can be naturally returned to the original straight shape.

The low rigidity portion 24 is formed in a bellows tube shape in this embodiment. Note that the shape is not particularly limited as long as it has flexibility. Specifically, a plurality of concave portions 26 and convex portions 27 formed in the circumferential direction are provided, and the concave portions 26 and the convex portions 27 are alternately arranged in the tube axis direction (extending direction of the high-voltage conductive path 15). Be placed.

As can be seen from the above description, the arrangement portion of the low-rigidity portion 24 is formed into a shape that becomes a corrugated tube. In other words, the exterior member 16 is partially formed in a shape having a corrugated tube. Since the exterior member 16 has a corrugated tube portion as described above, it can be called a “cortube” or a “partially formed corrugated tube”.

On the other hand, the high-rigidity portion 25 is formed as a portion that does not bend when the wire harness 9 is packed, transported, or routed. In addition, the part which does not bend means the part which does not give flexibility positively. The high-rigidity portion 25 is formed in a straight tube shape having a substantially rectangular cross section. The high-rigidity portion 25 is formed at a position and length that match the vehicle mounting shape. Since the high-rigidity portion 25 is formed in a straight tube shape (straight tube shape) as described above, it can be referred to as a “straight portion” or a “straight tube portion”.

The high rigidity portion 25 having a substantially rectangular cross section has a pair of parallel long side wall portions 28 (two parallel walls) and a pair of symmetrical short side wall portions 29 (two symmetric support walls). The pair of long side wall portions 28 are formed to extend in the horizontal direction when viewed in the cross-sectional state of FIG. In practice, the upper side in FIG. 3 is formed so as to face the vehicle floor 11 (see FIG. 1), and the lower side in FIG. 3 is formed to face the ground.

The pair of short side wall portions 29 are formed so as to extend in the vertical direction of FIG. The pair of short side wall portions 29 are formed in directions that are spaced apart from each other, that is, in a slightly curved shape that bulges outward. In addition to the curved shape, for example, a “<” shape may be used. However, it is premised on ensuring sufficient support. Such a pair of short side wall portions 29 is formed to support the pair of long side wall portions 28. The pair of short side wall portions 29 is formed so as to strengthen the high-rigidity portion 25 against an external force from the ground side, for example.

If the two-dot difference line PL in FIG. 3 is the parting line and the arrows Q and R are the parting direction, the pair of short side wall portions 29 is a shape with a good releasability with a draft. I understand that there is. If a straight wall (not shown; a wall perpendicular to the pair of long side wall portions 28) is given as a comparative example, the straight wall does not have a draft, so that it takes time to form. In this embodiment, since the pair of long side wall portions 28 have a drafted shape, the releasability is good, and therefore the molding time can be shortened.

Among the plurality of high-rigidity portions 25, those attached to the vehicle floor 11 (see FIG. 1) are formed in a long shape. The long and highly rigid portion 25 is attached, for example, along a lean hose.

The wire harness 9 having the above configuration and structure is manufactured as follows (not shown). That is, the wire harness 9 is manufactured by inserting the high-voltage conductive path 15 from one end to the other end of the exterior member 16 that is entirely resin-molded in a substantially linear shape. The wire harness 9 is manufactured by attaching a clamp, a grommet, a boot or the like to a predetermined position on the outer surface of the exterior member 16. Furthermore, the wire harness 9 is manufactured by providing a shield connector at the terminal portion of the high-voltage conductive path 15.

After being manufactured as described above, when the predetermined low-rigidity portion 24 is folded and bent, the packaging of the wire harness 9 is completed. The packaged wire harness 9 is compact, and is transported to the vehicle assembly site in such a compact state.

At the vehicle assembly site, the wire harness 9 is attached to the vehicle from a long portion corresponding to the vehicle underfloor 11 (see FIG. 1). Since the high-rigidity portion 25 of the exterior member 16 is disposed in a long portion corresponding to the vehicle underfloor 11, the wire harness 9 is attached in a state in which bending is suppressed. At this time, the wire harness 9 is attached with good workability. After the long portion corresponding to the vehicle lower floor 11 is fixed with a clamp or the like, the remaining portion is attached while bending (bending) the portion of the low-rigidity portion 24 in the exterior member 16. When a series of operations related to attachment is completed, the wire harness 9 is routed along a desired route.

As described above with reference to FIGS. 1 to 3, the wire harness 9 according to the present embodiment includes the high-voltage conductive path 15 and the exterior member 16. A structure in which the low-rigidity portion 24 and the high-rigidity portion 25 are continuous in the extending direction is employed. Since the exterior member 16 is employed, there is no need to use a plurality of types of exterior members as in the prior art, or to further use, for example, a plurality of types of the plurality of types. Therefore, the number of parts can be minimized as compared with the conventional case. Therefore, the exterior member 16 having the structure described above has an effect that costs and man-hours can be reduced. In addition, there is an effect that parts management can be facilitated.

Further, the wire harness 9 according to the present embodiment is a wire harness with good workability in a state in which bending is suppressed since the high-rigidity portion 25 is disposed in the long portion corresponding to the vehicle underfloor 11 with respect to the exterior member 16. 9 can be attached. Therefore, there is an effect that workability can be improved.

In addition, the wire harness 9 according to the present invention can reduce the height of the high-rigidity portion 25 of the exterior member 16 compared to, for example, a circular cross-section because the cross-sectional shape is substantially rectangular. . Therefore, if the highly rigid part 25 is arrange | positioned under the vehicle floor 11, there exists an effect that it can make it difficult to receive the influence from the ground side. In addition, the function and reliability of the wire harness 9 can be maintained.

In addition, the wire harness 9 according to the present invention has a structure having a pair of long side wall portions 28 and a pair of short side wall portions 29 with respect to the high rigidity portion 25 of the exterior member 16, so that the structure is not easily damaged. There is an effect that can be done. Moreover, the effect that it can give sufficient intensity | strength and the effect that a mold release property can be improved and manufacturability can be improved are also show | played.

Hereinafter, Example 2 will be described with reference to the drawings. FIG. 4 is a perspective view of a modified wire harness. FIG. 5 is a sectional view taken along line BB in FIG.

4 and 5, the wire harness 9 includes the same high-voltage conductive path 15 (conductive path) as that of the first embodiment, and an exterior member 16 that accommodates and protects the high-voltage conductive path 15. The exterior member 16 includes a plurality of low-rigidity portions 24 having flexibility and a plurality of high-rigidity portions 25 that do not actively have flexibility, such as the low-rigidity portions 24. Formed.

The high rigidity portion 25 has a pair of parallel long side wall portions 28 (two parallel walls) and a pair of symmetrical short side wall portions 29 (two symmetric support walls). A plurality of deformation portions 30 are formed on the side wall portion 28. The deformation portion 30 is formed by deforming the outer wall surface 31 outward and by deforming the outer wall surface 32 so as to follow the outer deformation. The deformable portion 30 is formed in a straight shape along the tube axis direction (extending direction of the high-voltage conductive path 15). Note that the reference numeral 33 in the deformable portion 30 indicates a convex portion, and the reference numeral 34 indicates a concave portion.

The high-rigidity portion 25 has a plurality of circumferentially deformable portions 35 in addition to the deformable portion 30 in the tube axis direction. The deforming portion 35 is formed across the pair of long side wall portions 28 and the pair of short side wall portions 29, in other words, over the entire circumference. The deformation part 35 is formed in the same shape as the deformation part 30 only in the formation direction.

In the above configuration and structure, the wire harness 9 according to the present embodiment includes the deformed portion 30 with respect to the high-rigidity portion 25 of the exterior member 16, and thus can be given strength. Therefore, there is an effect that it is possible to make the structure difficult to break, and an effect that sufficient strength can be provided.

Moreover, since the deformation | transformation part 30 and the deformation | transformation part 35 are the shapes which follow the wall inner surface 32 with the deformation | transformation to an outer side, compared with the case where the concave shape part 34 does not arise, for example, the amount of resin can be decreased. . If the amount of resin can be reduced in this way, cooling during molding can be accelerated. Therefore, it is possible to increase the molding speed, thereby producing the exterior member 16 with good manufacturability.

Furthermore, the deformation part 30 and the deformation part 35 can increase the surface area by the above deformation. Therefore, there is an effect that the cooling at the time of molding can be accelerated, and the heat dissipation at the time of use can be enhanced.

In addition, the deformation | transformation part 30 is effective as a part which recognizes the attachment position of retrofit components, such as a clamp, for example.

Of course, the present invention can be variously modified without departing from the spirit of the present invention.

In the above description, the cross-sectional shape of the exterior member 16 is formed in a substantially rectangular shape, but is not limited to such a cross-sectional shape. That is, it may be a circular shape, an oval shape, an elliptical shape, or the like.
