[0031] Hereinafter, embodiments of the present invention will be described in detail based on the accompanying drawings. In addition, the present invention is not limited to these embodiments. In addition, the constituent elements in the following embodiments include elements that can be easily replaced by those skilled in the art, or substantially the same elements.

[0032] [Example]

[0033] Figure 1 The wire harness routing structure 1 shown is suitable for use in vehicles such as automobiles, and is used for connecting various devices mounted on the vehicle and for power supply and signal communication.

[0034] like Figure 1 As shown, the wire harness routing structure 1 includes a wire harness 10 and a groove portion 20 provided on the vehicle body and formed along the routing path of the wire harness 10. In addition, the wire harness 10 is constructed to include a wiring material W having conductivity and an exterior component 100 mounted on the wiring material W. Furthermore, the wire harness routing structure 1 of this embodiment realizes a structure capable of improving assembly performance into a vehicle by forming the exterior component 100 from a sheet component M and using a protrusion 130 formed by bending the sheet component M as a fitting portion relative to the groove portion 20. hereinafter, with reference to Figures 1 to 3 Each structure of the wire harness routing structure 1 will be described in detail.

[0035] Furthermore, the wire harness 10 may be configured to further include grommets, fixings, connectors, and the like in addition to these components.

[0036] In addition, in the following description, the first direction among the first direction, the second direction, and the third direction that intersect each other is referred to as the "length direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the length direction X, the width direction Y, and the height direction Z are orthogonal to each other. In addition, the length direction X is typically equivalent to the wiring direction of the wire harness 10, the length direction of the groove 20, etc. In addition, the width direction Y is typically equivalent to the width direction of the groove 20, etc. In addition, the height direction Z is typically equivalent to the height direction (thickness direction) of the groove 20, the fitting direction of the protrusion 130 relative to the groove 20, etc. In addition, unless otherwise specified, the directions used in the following description are described as directions in a state where the exterior component 100 is assembled in the groove 20 via the protrusion 130.

[0037] [Wire harness]

[0038] In order to connect various devices mounted on the vehicle, the wiring harness 10 bundles a plurality of wiring materials W for power supply and signal communication as a collective component, and connects the plurality of wiring materials W to the various devices using connectors or the like. Figures 1 to 3As shown, the wire harness 10 of the present embodiment is configured to include a wiring material W and an exterior member 100 .

[0039] The wiring material W is wired in the vehicle to electrically connect the various devices. The wiring material W of this embodiment is composed of a conductive conductor part (core wire) and an insulating coating part with insulation, and is an insulated wire in which the conductor part is covered with the insulating coating part. The conductor part mentioned here is a stranded wire formed by twisting together a plurality of wires made of conductive metal. In addition, the insulating coating part is formed, for example, by extruding an insulating resin material (PP, PVC, cross-linked PE, etc., appropriately selected in consideration of wear resistance, chemical resistance, heat resistance, etc.). In addition, the conductor part of the wiring material W can also be formed by bundling a plurality of wires. In addition, the wiring material W can be one piece, or it can be a wiring material bundle formed by bundling two or more wiring materials.

[0040] The exterior member 100 is formed of an insulating resin material, and a wiring material W is inserted into the interior. In addition, the exterior member 100 is formed by bending a rectangular sheet member M continuously extruded in the longitudinal direction to form each part integrally. Figures 1 to 3 As shown, the exterior member 100 of this embodiment includes a main body 110 , an engaging portion 120 , and a protrusion 130 .

[0041] The main body 110 is a portion in which the wiring material W is inserted. Figures 1 to 3 As shown, the main body 110 of this embodiment is formed by bending the sheet member M into a cylindrical shape, and the cross-sectional shape along the height direction Z is formed into a substantially circular shape. In addition, the main body 110 is configured to include a storage space portion 110S as an internal space (see Figure 2 、 Figure 3 ), the mounting opening 111 opened in the height direction Z (refer to Figure 3 ), and a pair of insertion openings 112 opened in the longitudinal direction X (see Figure 1 ). In addition, the installation opening portion 111 mentioned here is an opening portion formed in a straight line along the longitudinal direction X, and is an opening portion formed by the ends of the short side direction of the sheet member M bent into a cylindrical shape facing each other. In addition, a pair of insertion opening portions 112 are opening portions respectively formed at the ends of the longitudinal direction X of the main body portion 110, and are opening portions respectively formed by the ends of the longitudinal direction of the sheet member M. Therefore, the main body 110 of this embodiment allows the wiring material W to be inserted from the installation opening portion 111, and the wiring material W is inserted into the storage space portion 110S through the pair of insertion opening portions 112, so that the wiring material W can be wired along the longitudinal direction X which is the extension direction of the main body 110 (refer to Figure 1 ).

[0042] The engaging portion 120 is a portion for engaging the end portions of the sheet member M formed in the mounting opening 111 of the main body 110 (end portions Ma and Mb to be described later). Figure 1 As shown in FIG. 1 , the engaging portion 120 of this embodiment is formed along the length direction of the sheet member M (the length direction X of the main body 110). Figure 2 、 Figure 3 As shown, the engaging portion 120 is configured to include a male engaging portion 121 and a female engaging portion 122 .

[0043] The male engaging portion 121 is a portion that stops the female engaging portion 122. Figure 2 、 Figure 3 As shown, the male engaging portion 121 of this embodiment is integrally formed at the end Ma on one side in the short side direction of the sheet member M. In addition, the cross-sectional shape of the male engaging portion 121 as viewed from the longitudinal direction X is formed into a substantially C-shaped shape, and a slit 121a (see FIG. 1 ) into which the female engaging portion 122 can be inserted is provided. Figure 2 ).

[0044] The female engaging portion 122 is a portion that is engaged with the male engaging portion 121. Figure 2 、 Figure 3 As shown, the female engaging portion 122 of the present embodiment is integrally formed at the end portion Mb on the other side in the short side direction of the sheet member M. In addition, the cross-sectional shape of the female engaging portion 122 as viewed from the longitudinal direction X is formed into a substantially T-shape, and is formed into a claw shape that can engage with the male engaging portion 121. Therefore, in the engaging portion 120 of the present embodiment, the female engaging portion 122 is inserted from the slit 121a of the male engaging portion 121, and the engaging state of the engaging portion 120 (the state in which the male engaging portion 121 and the female engaging portion 122 are engaged) is continuously maintained, thereby being able to close the mounting opening 111 of the main body 110 (see Figure 2 ). In addition, by pulling out the female engaging portion 122 from the slit 121a of the male engaging portion 121, the engaging state of the engaging portion 120 is released, so that the engaging portion 120 can open the mounting opening 111 of the main body 110 (refer to Figure 3 ).

[0045] The protrusion 130 is a portion that fits into the groove 20. Figure 1 As shown, the protrusion 130 of this embodiment is provided at the bottom of the main body 110 and is formed integrally with the main body 110. In addition, the protrusion 130 is formed by bending the sheet member M outward and is in a shape protruding from the main body 110. In addition, the protrusion 130 is formed along the longitudinal direction of the sheet member M (the longitudinal direction X of the main body 110). In addition, as shown in FIG. Figure 2As shown, the protrusion 130 is composed of a pair of vertical wall portions 131 and a connecting wall portion 132 , and these portions are integrally formed so that the cross-sectional shape viewed in the longitudinal direction X is formed into a substantially U-shape.

[0046] The pair of vertical wall portions 131 are wall portions that protrude from the main body portion 110. Figure 2 As shown, the pair of vertical walls 131 of this embodiment are formed to protrude from the main body 110 in the height direction Z. The pair of vertical walls 131 are spaced apart along the width direction Y and are provided at positions facing each other along the width direction Y.

[0047] The connecting wall portion 132 is a wall portion that connects the vertical wall portions 131 to each other. Figure 2 As shown, the connecting wall portion 132 of 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 top ends of the vertical wall portions 131 .

[0048] In addition, the protrusion 130 is configured to be elastically deformable. When elastically deformed when inserted into the groove 20, the protrusion 130 abuts against the inner surface of the groove 20 by the reaction force accompanying the elastic deformation. Figure 3 As shown, the protrusion 130 of this embodiment is inserted into the groove 20 and can be fitted into the groove 20 in a state of being elastically deformed to match the shape of the groove 20 .

[0049] Furthermore, the protrusion 130 is configured so that once engaged with the groove 20, it can remain engaged with the groove 20 regardless of the engagement state of the engaging portion 120. Therefore, in this embodiment, the engaging portion 120 can be released from the engaged state while the protrusion 130 is engaged with the groove 20. When the engaged state is released while the wire harness 10 is secured to the groove 20 via the protrusion 130, only the wiring material W inserted through the exterior member 100 can be removed while the exterior member 100 is secured to the groove 20. Furthermore, the engaging portion 120 can be restored to the engaged state while the protrusion 130 is engaged with the groove 20, allowing the wiring material W to be subsequently attached to the exterior member 100 secured to the groove 20 via the protrusion 130.

[0050] In addition, 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 relative to the groove 20. Figures 1 to 3As shown, the protrusion 130 is provided on one side in the height direction Z (the groove 20 side, the inner side of the protrusion 130 in the direction of engagement with the groove 20), and the engaging portion 120 is provided on the other side in the height direction Z (the side opposite the groove 20 side, the front side of the protrusion 130 in the direction of engagement with the groove 20). Therefore, when the engaging portion 120 is released from the engagement state of the exterior member 100 of this embodiment while the protrusion 130 is engaged with the groove 20, only the wiring material W can be easily removed from the front side where the engaging portion 120 is provided. Furthermore, while the exterior member 100 is secured to the groove 20 via the protrusion 130, the wiring material W can be easily installed from the front side where the engaging portion 120 is provided.

[0051] [Groove]

[0052] The groove 20 is formed between the devices connected by the wire harness 10 and is formed in a straight line along a predetermined wiring path of the wire harness 10 (in the longitudinal direction X in this embodiment). Figure 2 、 Figure 3 As shown, the groove portion 20 of this embodiment is configured to include a narrow width portion 21 and a wide width portion 22 .

[0053] The narrow width portion 21 is a portion into which the protrusion 130 of the exterior member 100 is inserted. Figure 2 As shown, the opening width 21y of the narrow portion 21 (the length of the narrow 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 portion 21 (see FIG. 1 ) by elastically deforming the pair of vertical wall portions 131 inwardly in accordance with the opening width 21y of the narrow portion 21. Figure 3 ).

[0054] The wide portion 22 is a portion that receives the top end of the protrusion 130 of the exterior member 100. Figure 2 As shown, the wide portion 22 is connected to the narrow portion 21. In addition, the opening width 22y of the wide portion 22 (the length of the wide portion 22 in the width direction Y) is configured to be wider than the opening width 21y of the narrow portion 21 (the length of the narrow portion 21 in the width direction Y). Figure 3 As shown, in the state where the top end of the protrusion 130 of this embodiment is accommodated in the wide portion 22, the pair of vertical wall portions 131 are brought into contact with the inner surface of the narrow portion 21 by the reaction force accompanying the elastic deformation (restoration force of the vertical wall portion 131), thereby being able to fit relative to the groove portion 20. In addition, the exterior component 100 of this embodiment can fix the main body 110 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 110 can be along the extending direction of the groove portion 20 (refer to Figure 1). Therefore, the wire harness routing structure 1 of the present embodiment can appropriately route the wiring material W along the predetermined routing path of the wire harness 10.

[0055] The wire harness routing structure 1 described above includes a wire harness 10 and a groove 20 provided on a vehicle body and formed along the routing path of the wire harness 10. The wire harness 10 is configured to include: a conductive wiring member W; and an exterior member 100 formed from a sheet member M and attached to the wiring member W. The exterior member 100 includes: a main body 110 formed by bending the sheet member M into a cylindrical shape, into which the wiring member W can be inserted; an engaging portion 120 capable of engaging the ends Ma and Mb of the sheet member M with each other when the main body 110 is formed; and a protrusion 130 formed by bending the sheet member M outward and projecting from the main body 110. The protrusion 130 is inserted into the groove 20 and engages with the groove 20 while elastically deforming to match the shape of the groove 20.

[0056] According to such a structure, the main body 110 and the protrusion 130 of the exterior component 100 are formed integrally. Therefore, the wire harness 10 does not need to prepare a separate fixing component such as a clamping portion, and can be manufactured without performing a subsequent process (for example, a tape winding process, etc.) to fix the fixing component to the main body 110. In addition, since the wire harness 10 is composed of a single sheet component M, the wiring material W can be easily assembled with respect to the main body 110 and the protrusion 130 can be easily assembled with respect to the vehicle body. Therefore, the wire harness 10 can easily change or supplement the circuit according to changes in specifications, etc. In addition, the wire harness 10 can appropriately fix the main body 110 formed integrally with the protrusion 130 and the wiring material W inserted into the interior of the main body 110 along the wiring path of the wire harness 10 by fitting the elastically deformable protrusion 130 into the groove 20 formed along a predetermined wiring path. Therefore, the wire harness wiring structure 1 of this embodiment can improve the assembly performance in the vehicle.

[0057] Furthermore, the engaging portion 120 described above can be released from the engaging state while the protrusion 130 is engaged with the groove 20. With this structure, the operator can remove only the wiring material W inserted into the interior of the main body 110 while the wire harness 10 is secured to the groove 20 via the protrusion 130. Furthermore, the operator can later install the wiring material W while only the exterior component 100 is secured to the groove 20 via the protrusion 130. Therefore, the operator can appropriately change the order of assembling the wiring material W to the main body 110 and the protrusion 130 to the vehicle body, depending on the specifications of the wire harness 10. Therefore, the wire harness routing structure 1 of this embodiment can improve assembly ease into a vehicle.

[0058] Furthermore, the engaging portion 120 and the protrusion 130 described above are positioned so as to oppose each other along the direction in which the protrusion 130 engages the groove 20 (the height direction Z). With this structure, a worker can easily remove only the wiring material W from the front side while the wire harness 10 is secured to the groove 20 via the protrusion 130. Furthermore, a worker can easily install the wiring material W from the front side while the wire harness 10 is secured to the groove 20 via the protrusion 130. Therefore, the wire harness routing structure 1 of this embodiment simplifies assembly of the wire harness 10 to the vehicle body, thereby improving ease of assembly into the vehicle.

[0059] Furthermore, the protrusion 130 described above is constructed to include a pair of vertical walls 131 projecting from the main body 110 along the mating direction (height direction Z) relative to the groove 20, and a connecting wall 132 connecting the vertical walls 131. With this structure, the protrusion 130 can be mated with the groove 20 by elastically deforming the pair of vertical walls 131 inward to match the shape of the groove 20. Therefore, the wire harness routing structure 1 of this embodiment simplifies assembly of the wire harness 10 into the vehicle body, thereby improving ease of assembly into the vehicle.

[0060] 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 can be made within the scope of the claims.

[0061] For example, the positional relationship between the engaging portion 120 and the protrusion 130 is not particularly limited to Figures 1 to 3 The method shown.

[0062] The shapes of the male engagement portion 121 and the female engagement portion 122 constituting the engagement portion 120 are not particularly limited as long as they are engageable.

[0063] The shape of the protrusion 130 is not particularly limited as long as it can be fitted into the groove 20 .

[0064] The shape (extension direction) of the groove 20 is not particularly limited. Furthermore, while the groove 20 is formed linearly in the above-described embodiment, it may also include a portion that curves according to the set wiring path of the wire harness 10. The protrusion 130 is fitted in a curved position that matches the shape of the groove 20, thereby appropriately securing the wiring material W inserted into the main body 110 along the curved wiring path of the wire harness 10.

[0065] In addition, the cross-sectional shape of the groove portion 20 is not particularly limited.

[0066] Furthermore, the wire harness routing structure 1 and the wire harness 10 of the present embodiment may be configured by appropriately combining the constituent elements of the above-described embodiments.
