[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially the same.

[0011] [Embodiment] A wire harness routing structure 1 shown in FIG. 1 is applied to a vehicle such as an automobile, and is used to connect devices mounted on the vehicle for power supply and signal communication.

[0012] As shown in Fig. 1, the wire harness routing structure 1 includes a wire harness 10 and a groove 20 provided on the body of a vehicle and formed along the routing path of the wire harness 10. The wire harness 10 also includes a conductive routing material W and an exterior member 100 attached to the routing material W. The wire harness routing structure 1 of this embodiment realizes a configuration in which the exterior member 100 is formed of a sheet member M, and a protrusion 130 formed by bending the sheet member M is used as a fitting portion for the groove 20, thereby improving the ease of assembly to the vehicle. Hereinafter, each component of the wire harness routing structure 1 will be described in detail with reference to Figs. 1 to 3.

[0013] The wire harness 10 may further include a grommet, a fixture, a connector, and the like.

[0014] In the following description, among the first, second, and third directions that intersect with one another, the first direction will be referred to as the "length direction X," the second direction will be referred to as the "width direction Y," and the third direction will be referred to as the "height direction Z." Here, the length direction X, the width direction Y, and the height direction Z are perpendicular to one another. The length direction X typically corresponds to the routing direction of the wire harness 10, the length direction of the groove portion 20, etc. The width direction Y typically corresponds to the width direction of the groove portion 20, etc. The height direction Z typically corresponds to the height direction (thickness direction) of the groove portion 20, the fitting direction of the protrusion portion 130 into the groove portion 20, etc. Unless otherwise specified, each direction used in the following description will be described as a direction in a state in which the exterior member 100 is assembled into the groove portion 20 via the protrusion portion 130.

[0015] [Wire harness] The wire harness 10 is an assembly component made by bundling a plurality of wiring materials W used for power supply and signal communication to connect various devices mounted on a vehicle, and the wiring materials W are connected to the various devices by connectors, etc. As shown in Figs. 1 to 3, the wire harness 10 of this embodiment is configured to include wiring materials W and an exterior member 100.

[0016] The wiring material W is wired in a vehicle and electrically connects various devices. The wiring material W of this embodiment is an insulated electric wire that includes a conductive conductor portion (core wire) and an insulating insulating coating portion, and the conductor portion is coated with the insulating coating portion. The conductor portion here is a stranded wire formed by twisting together multiple wires made of a conductive metal. The insulating coating portion is formed, for example, by extrusion molding an insulating resin material (PP, PVC, cross-linked PE, etc., appropriately selected taking into consideration abrasion resistance, chemical resistance, heat resistance, etc.). The conductor portion of the wiring material W may be a bundle of multiple wires. The wiring material W may be a single piece, or a wiring material bundle formed by bundling two or more wiring materials.

[0017] The exterior member 100 is made of an insulating resin material, and has a wiring material W inserted therethrough. The exterior member 100 is formed by folding a rectangular sheet member M that is continuously extruded in the longitudinal direction to form each part integrally. As shown in FIGS. 1 to 3, the exterior member 100 of this embodiment includes a main body 110, an engaging portion 120, and a protruding portion 130.

[0018] The main body 110 is a portion through which the wiring material W is inserted. As shown in FIGS. 1 to 3, the main body 110 of this embodiment is formed by bending a sheet member M into a cylindrical shape, and has a substantially circular cross-sectional shape along the height direction Z. The main body 110 includes a storage space 110S (see FIGS. 2 and 3) as an internal space, an attachment opening 111 (see FIG. 3) that opens in the height direction Z, and a pair of insertion openings 112 (see FIG. 1) that open in the length direction X. The attachment opening 111 here is an opening that is linearly formed along the length direction X and is formed by joining the short-side ends of the sheet member M that has been folded into a cylindrical shape. The pair of insertion openings 112 are openings that are respectively formed at the ends of the main body 110 in the length direction X and are openings that are respectively formed by the long-side ends of the sheet member M. Therefore, in this embodiment, the main body 110 has the wiring material W inserted through the mounting opening 111, and the wiring material W is inserted into the storage space 110S through a pair of insertion openings 112, so that the wiring material W can be wired along the length direction X, which is the extension direction of the main body 110 (see Figure 1).

[0019] The engaging portion 120 is a portion that engages the ends (ends Ma and Mb, described later) of the sheet member M that form the attachment opening 111 of the main body portion 110. As shown in Fig. 1, the engaging portion 120 of this embodiment is formed along the longitudinal direction of the sheet member M (length direction X of the main body portion 110). Here, the engaging portion 120 includes a male engaging portion 121 and a female engaging portion 122, as shown in Figs. 2 and 3.

[0020] The male engaging portion 121 is a portion that engages with the female engaging portion 122. As shown in Figures 2 and 3, the male engaging portion 121 of this embodiment is integrally formed with an end portion Ma on one side in the short direction of the sheet member M. The male engaging portion 121 has a substantially C-shaped cross section when viewed from the longitudinal direction X, and is provided with a slit 121a into which the female engaging portion 122 can be inserted (see Figure 2).

[0021] The female engaging portion 122 is a portion that is locked to the male engaging portion 121. As shown in FIGS. 2 and 3, the female engaging portion 122 of this embodiment is integrally formed with the end portion Mb on the other side in the short direction of the sheet member M. The female engaging portion 122 has a substantially T-shaped cross section when viewed from the longitudinal direction X, and is formed into a claw shape that can engage with the male engaging portion 121. Therefore, the engaging portion 120 of this embodiment can close the mounting opening 111 of the main body portion 110 by inserting the female engaging portion 122 through the slit 121a of the male engaging portion 121 and maintaining the engaged state of the engaging portion 120 (a state in which the male engaging portion 121 and the female engaging portion 122 are engaged) (see FIG. 2). In addition, when the female engaging portion 122 is removed from the slit 121a of the male engaging portion 121 and the engaging state of the engaging portion 120 is released, the mounting opening 111 of the main body portion 110 can be opened (see Figure 3).

[0022] The protrusion 130 is a portion that fits into the groove 20. As shown in FIG. 1, the protrusion 130 of this embodiment is provided on the bottom of the main body 110 and is formed integrally with the main body 110. The protrusion 130 is formed by bending the sheet member M outward, and has a shape that protrudes from the main body 110. The protrusion 130 is formed along the longitudinal direction of the sheet member M (the length direction X of the main body 110). As shown in FIG. 2, the protrusion 130 is composed of a pair of vertical wall portions 131 and a connecting wall portion 132, and the respective portions are formed integrally, so that the cross section viewed from the length direction X is formed into a substantially U-shape.

[0023] The pair of vertical wall portions 131 are wall portions formed to protrude from the main body portion 110. As shown in Fig. 2, the pair of vertical wall portions 131 of this embodiment are formed to protrude from the main body portion 110 in the height direction Z. Furthermore, the pair of vertical wall portions 131 are arranged at an interval along the width direction Y and are provided at positions facing each other along the width direction Y.

[0024] The connecting wall portion 132 is a wall portion that connects the vertical wall portions 131. As shown in Fig. 2 , the connecting wall portion 132 in this embodiment is located between the vertical wall portions 131 in the width direction Y, and both ends in the width direction Y are connected to the tip ends of the vertical wall portions 131, respectively.

[0025] Furthermore, the protrusion 130 is configured to be elastically deformable, and when it elastically deforms when inserted into the groove 20, it utilizes the reaction force associated with the elastic deformation to come into contact with the inner surface of the groove 20. Therefore, the protrusion 130 of this embodiment can be inserted into the groove 20 and fitted into the groove 20 in a state where it has elastically deformed to match the shape of the groove 20, as shown in FIG.

[0026] Furthermore, once the protrusion 130 is fitted into the groove 20, it is configured to be able to maintain the fitted state in the groove 20 regardless of the engagement state of the engagement portion 120. Therefore, the engagement portion 120 of this embodiment can release the engagement state with the protrusion 130 fitted into the groove 20, and when the engagement state is released with the wire harness 10 fixed to the groove 20 via the protrusion 130, only the routing material W inserted into the routing material 100 can be removed while the exterior member 100 remains fixed to the groove 20. Furthermore, the engagement portion 120 can return to the engagement state with the protrusion 130 fitted into the groove 20, and the routing material W can be attached later to the exterior member 100 fixed to the groove 20 via the protrusion 130.

[0027] Furthermore, the engaging portion 120 and the protrusion 130 are provided at positions facing each other along the fitting direction (height direction Z) of the protrusion 130 to the groove 20. As shown in FIGS. 1 to 3 , the protrusion 130 is provided on one side in the height direction Z (the groove 20 side, the rear side in the fitting direction of the protrusion 130 to the groove 20), and the engaging portion 120 is provided on the other side in the height direction Z (the opposite side to the groove 20 side, the front side in the fitting direction of the protrusion 130 to the groove 20). Therefore, in the exterior member 100 of this embodiment, when the engagement state of the engaging portion 120 is released while the protrusion 130 is fitted into the groove 20, only the wiring material W can be easily removed from the front side where the engaging portion 120 is provided. Furthermore, when the exterior member 100 is fixed to the groove 20 via the protrusion 130, the wiring material W can be easily attached from the front side where the engaging portion 120 is provided.

[0028] [Groove] The groove portion 20 is formed between devices connected by the wire harness 10, and is formed linearly along a preset routing path (length direction X in this embodiment) of the wire harness 10. As shown in Figs. 2 and 3, the groove portion 20 in this embodiment includes a narrow portion 21 and a wide portion 22.

[0029] The narrow width portion 21 is a portion into which the protrusion 130 of the exterior member 100 is inserted. As shown in Fig. 2, the opening width 21y of the narrow width portion 21 (the length of the narrow width portion 21 in the width direction Y) is configured to be narrower than the opening width 130y of the protrusion 130 (the length of the protrusion 130 in the width direction Y). Therefore, the protrusion 130 of this embodiment is inserted into the narrow width portion 21 by elastically deforming the pair of vertical wall portions 131 inward to match the opening width 21y of the narrow width portion 21 (see Fig. 3).

[0030] The wide portion 22 is a portion that accommodates the tip end of the protrusion 130 of the exterior member 100. As shown in FIG. 2, the wide portion 22 is connected to the narrow portion 21. The opening width 22y (the length of the wide portion 22 in the width direction Y) of the wide portion 22 is configured to be wider than the opening width 21y (the length of the narrow portion 21 in the width direction Y). Therefore, as shown in FIG. 3, the protrusion 130 of this embodiment can be fitted into the groove portion 20 by abutting the pair of vertical wall portions 131 against the inner surface of the narrow portion 21 using a reaction force (the restoring force of the vertical wall portions 131) accompanying elastic deformation while the tip end is accommodated in the wide portion 22. Furthermore, in the exterior member 100 of this embodiment, the main body portion 110 is fixed to the groove portion 20 via the protrusion 130, so that the central axis L1 of the wiring material W inserted into the main body portion 110 can be aligned with the extending direction of the groove portion 20 (see FIG. 1). Therefore, the wire harness routing structure 1 of this embodiment can properly route the routing material W along the routing path of the wire harness 10 that is set in advance.

[0031] The wire harness routing structure 1 described above includes a wire harness 10 and a groove 20 that is provided on a vehicle body and formed along a routing path of the wire harness 10. The wire harness 10 is configured to include a conductive routing material W and an exterior member 100 that is made of a sheet member M and attached to the routing material W. The exterior member 100 has a main body 110 that is formed by bending the sheet member M into a cylindrical shape and through which the routing material W can be inserted, an engaging portion 120 that can engage ends Ma and Mb of the sheet member M in a state in which the main body 110 is formed, and a protrusion 130 that is formed by bending the sheet member M outward and has a shape that protrudes from the main body 110. The protrusion 130 is inserted into the groove 20 and fits into the groove 20 in a state in which it is elastically deformed to match the shape of the groove 20.

[0032] According to this configuration, the exterior member 100 has the main body 110 and the protrusions 130 integrally formed. Therefore, the wire harness 10 does not need to have a separate fixing member such as a clip, and can be manufactured without performing a post-process (e.g., a tape winding process) for fixing the fixing member to the main body 110. Furthermore, by forming the exterior member 100 from a single sheet member M, the wire harness 10 can easily assemble the wiring material W to the main body 110 and the protrusions 130 to the vehicle body. Therefore, the wire harness 10 can easily have its circuits changed or added in accordance with specification changes, etc. Furthermore, by fitting the elastically deformable protrusions 130 into the grooves 20 formed along a predetermined wiring path, the main body 110 formed integrally with the protrusions 130 and the wiring material W inserted inside the main body 110 can be properly fixed along the wiring path of the wire harness 10. Therefore, the wire harness routing structure 1 of this embodiment can improve the ease of assembly into a vehicle.

[0033] Furthermore, the engaging portion 120 described above can be released from the engaged state when the protrusion 130 is fitted into the groove 20. With this configuration, the worker can remove only the wiring material W inserted inside the main body 110 while the wire harness 10 is fixed to the groove 20 via the protrusion 130. Also, the worker can later install the wiring material W while only the exterior member 100 is fixed to the groove 20 via the protrusion 130. Therefore, the worker can appropriately change the order of assembling the wiring material W to the main body 110 and assembling the protrusion 130 to the vehicle body in accordance with the specifications of the wire harness 10. Therefore, the wire harness routing structure 1 of this embodiment can improve the ease of assembly into a vehicle.

[0034] Furthermore, the engaging portion 120 and the protrusion 130 described above are provided at positions facing each other along the fitting direction (height direction Z) of the protrusion 130 with respect to the groove 20. With this configuration, the worker can easily remove only the wiring material W from the front side in a state where the wire harness 10 is fixed to the groove 20 via the protrusion 130. Also, the worker can easily attach the wiring material W from the front side in a state where the wire harness 10 is fixed to the groove 20 via the protrusion 130. Therefore, the wire harness routing structure 1 of this embodiment can simplify the assembly of the wire harness 10 to the vehicle body, thereby improving the ease of assembly to the vehicle.

[0035] Furthermore, the protrusion 130 described above includes a pair of vertical wall portions 131 formed protruding from the main body 110 along the fitting direction (height direction Z) with respect to the groove 20, and a connecting wall portion 132 connecting the vertical wall portions 131 to each other. With this configuration, the protrusion 130 can fit into the groove 20 by elastically deforming the pair of vertical wall portions 131 inward to match the shape of the groove 20. Therefore, the wire harness routing structure 1 of this embodiment can simplify the assembly of the wire harness 10 to the vehicle body, thereby improving the ease of assembly into the vehicle.

[0036] The wire harness routing structure 1 and the wire harness 10 according to the above-described embodiment of the present invention are not limited to the above-described embodiment, and various modifications are possible within the scope of the claims.

[0037] For example, the positional relationship between the engaging portion 120 and the protruding portion 130 is not particularly limited to the form shown in FIGS.

[0038] Furthermore, the shapes of the male engaging portion 121 and the female engaging portion 122 that make up the engaging portion 120 are not particularly limited as long as they are shapes that allow engagement.

[0039] Furthermore, the shape of the protrusion 130 is not particularly limited as long as it is a shape that can be fitted into the groove 20 .

[0040] Furthermore, there is no particular limitation on the shape (extension direction) of the groove portion 20. Furthermore, although the groove portion 20 is formed linearly in the above-described embodiment, it may have a curved portion according to the set wiring path of the wire harness 10, and the protrusion portion 130 fits into the groove portion 20 in a curved position according to the shape of the groove portion 20, thereby making it possible to properly fix the wiring material W inserted inside the main body portion 110 along the curved wiring path of the wire harness 10.

[0041] The cross-sectional shape of the groove 20 is not particularly limited.

[0042] The wire harness routing structure 1 and the wire harness 10 according to this embodiment may be configured by appropriately combining the components of the above-described embodiments. [Explanation of symbols]
