[0022] [Description of embodiments of this disclosure]

[0023] First, embodiments of this disclosure will be described.

[0024] The wire harness disclosed herein,

[0025] [1] Installed on a vehicle body, the wiring harness includes: a wiring harness body having wires and an outer component covering the wires; a first path limiting member installed on the outer periphery of the outer component to limit the path of a straight portion of the wiring harness body; a second path limiting member installed on the outer periphery of the outer component to limit the path of a bent portion of the wiring harness body; and a locking member engaging with the second path limiting member in the circumferential direction of the wiring harness body, the first path limiting member having an insertion port extending along the length direction of the first path limiting member and throughout the entire length of the first path limiting member, the locking member being disposed within the insertion port, the second path limiting member having a first locking portion as a protrusion or recess, the locking member having a second locking portion engaging with the first locking portion in a concave-convex manner, and engaging with the first locking portion in the circumferential direction of the wiring harness body.

[0026] According to this structure, the wire harness includes a first path limiting member that limits straight sections in the path of the wire harness body, and a second path limiting member that limits bent sections in the path of the wire harness body. Therefore, the position of the first path limiting member relative to the second path limiting member can be adjusted in the length direction of the wire harness body.

[0027] Furthermore, according to this structure, the insertion port of the first path limiting member is an opening extending along the length of the first path limiting member and extending throughout its entire length. Therefore, after end processing such as installing connectors at the ends of the wires along their length, the first path limiting member can be installed onto external components through the insertion port. This allows for the subsequent installation of the first path limiting member, thus improving the ease of wire harness assembly.

[0028] Furthermore, an engaging member that engages with the second path limiting member in the circumferential direction of the wire harness body is disposed within the insertion port of the first path limiting member. According to this structure, the engaging member can be configured to contact the insertion port of the first path limiting member in the circumferential direction. Thus, the engaging member restricts the circumferential rotation of the first path limiting member, thereby suppressing circumferential rotation of the first path limiting member.

[0029] [2] In the circumferential direction of the wire harness body, the size of the engaging member is smaller than the size of the insertion port.

[0030] According to this structure, the engaging member can move circumferentially along the wire harness body within the insertion port of the first path limiting member. Therefore, the relative position of the first path limiting member with respect to the engaging member can be adjusted circumferentially along the wire harness body.

[0031] [3] One of the first engaging portion and the second engaging portion is a concave portion, and the other of the first engaging portion and the second engaging portion is a convex portion. In the circumferential direction of the wire harness body, the size of the concave portion is larger than the size of the convex portion.

[0032] According to this structure, the protrusion can move circumferentially within the recess along the main body of the wire harness. Therefore, the relative positions of the engaging member and the first path limiting member with respect to the second path limiting member can be adjusted circumferentially within the main body of the wire harness.

[0033] [4] The second path limiting member has a plurality of the first engaging portions, which are arranged circumferentially staggered from each other in the wire harness body.

[0034] According to this structure, it is possible to select which of the multiple first engaging parts in the second path limiting member the second engaging part of the engaging member will engage with, based on the path of the bending portion of the wire harness body. Therefore, the degree of freedom in the layout of the wire harness can be improved.

[0035] [5] The second path limiting member has a surrounding portion that surrounds the outer periphery of the first path limiting member. The surrounding portion has a part of the main body portion of the second path limiting member and a cover portion connected to the main body portion. The first engaging portion is disposed on the cover portion.

[0036] According to this structure, the enclosure portion is divided into a main body portion and a cover portion, thereby allowing the second path limiting member, including the enclosure portion, to be subsequently installed on the first path limiting member. This further improves the assembly operability of the wire harness.

[0037] [6] The insertion port in the first path limiting member is used as the first insertion port, and the main body has a second insertion port, which is an opening that extends along the length direction of the second path limiting member and throughout the entire length of the second path limiting member, and the cover partially covers the second insertion port in the length direction of the second path limiting member.

[0038] According to this structure, the second insertion port is an opening extending along the length of the second path limiting member, and extends along the entire length of the second path limiting member. Therefore, after end processing such as installing connectors at the ends of the wires along their length, the second path limiting member can be installed onto the external components through the insertion port. This allows for the subsequent installation of the second path limiting member, thus further improving the assembly workability of the wire harness.

[0039] [7] The vehicle body has an assembly surface for assembling the main body of the wiring harness, and the cover is arranged closer to the assembly surface than the main body.

[0040] According to this structure, in the second path limiting member, the first engaging portion, which engages with the engaging member disposed within the insertion port of the first path limiting member, is located in a cover portion closer to the assembly surface of the vehicle body. Furthermore, the position of the insertion port of the first path limiting member in the circumferential direction is positioned by the second path limiting member and the engaging member. That is, according to this structure, the insertion port of the first path limiting member can be configured to face the cover portion side of the second path limiting member, i.e., the assembly surface side of the vehicle body. Therefore, it is possible to prevent the insertion port of the first path limiting member from facing the side opposite to the assembly surface of the vehicle body.

[0041] [8] A first path limiting member is provided on each of the pair of straight sections arranged on both sides of the bend in the path of the wire harness body, and a locking member is provided at the insertion port of each pair of first path limiting members. According to this structure, the position of each first path limiting member arranged on both sides of the second path limiting member can be adjusted in the length direction of the wire harness body.

[0042] [9] The first path limiting member has: a first end and a second end, which are the two circumferential ends of the first path limiting member, forming the insertion port; and a protrusion that protrudes from the inner surface of at least one of the first end and the second end and contacts the outer surface of the outer component.

[0043] According to this structure, the first path limiting member has a protrusion that protrudes from the inner surface of at least one of the first end and the second end and contacts the outer surface of the outer component. Therefore, the first path limiting member can be appropriately prevented from disengaging from the outer component through the insertion port.

[0044]

[10] The protrusion protrudes from the inner surface of at least one of the top ends of the first end and the second end.

[0045] According to this structure, for example, compared to the case where the protrusion protrudes from the inner surface at a position slightly away from the top of the first end or the top of the second end, the path limiting member can be more effectively prevented from detaching from the outer component through the insertion port.

[0046] [Details of the embodiments of this disclosure]

[0047] Specific examples of the wiring harnesses of this disclosure are described below with reference to the accompanying drawings. In the drawings, for ease of explanation, sometimes a portion of the structure is shown enlarged or simplified. The dimensional ratios of the various parts sometimes differ in the drawings. Furthermore, the term "orthogonal" in this specification includes not only strictly orthogonal cases but also cases that are substantially orthogonal to the extent that they serve the function and effect of this embodiment. Moreover, the invention is not limited to these examples, but as indicated by the claims, it is intended to include all modifications within the meaning and scope equivalent to the claims.

[0048] Furthermore, the term "cylindrical" as used in this specification includes not only shapes with a continuous circumference, but also shapes formed by combining multiple components, and shapes such as a C-shape with a notch in a portion of the circumference. Additionally, "cylindrical" shapes include circles, ellipses, and polygons with pointed or rounded corners. Furthermore, the term "ring-shaped" as used in this specification refers to any structure forming a ring, a continuous shape without ends, and a generally ring-shaped structure with a gap, such as a C-shape. Additionally, "ring-shaped" shapes include circles, ellipses, and polygons with pointed or rounded corners, but are not limited to these.

[0049] (Overall structure of wire harness 10)

[0050] Figure 1 The wiring harness 10 shown connects devices installed in the vehicle V to each other, for example. The wiring harness 10 is configured in the vehicle V such that its middle portion in the longitudinal direction passes under the floor of the vehicle V or outside the passenger compartment.

[0051] The wiring harness 10 includes a wiring harness body 11. The wiring harness body 11 electrically connects a first device M1 and a second device M2 disposed in the vehicle V to each other. As an example of the first device M1 and the second device M2, the first device M1 is a high-voltage battery disposed near the rear of the vehicle V, and the second device M2 is an inverter disposed near the front of the vehicle V. The first device M1, as a high-voltage battery, is, for example, a battery capable of supplying a voltage of 100 volts or higher. The second device M2, as an inverter, is connected to an electric motor (not shown) that serves as the power source for the drive wheels of the vehicle. The inverter generates alternating current from the direct current (DC) power of the high-voltage battery and supplies this AC power to the electric motor. The wiring harness body 11 is wired along a path that is curved in a two-dimensional or three-dimensional shape.

[0052] (Structure of wire harness body 11)

[0053] like Figure 5 As shown, the main body 11 of the wire harness has wires 12 and external components 13.

[0054] For example, multiple wires 12 may be provided. Wires 12 may be, for example, sheathed wires. That is, wire 12 has a core wire 14 and an insulating covering 15 that encloses the outer periphery of the core wire 14. The core wire 14 may be made of, for example, a flexible conductor that can be easily bent. Furthermore, as an example of this flexible conductor, it may be a stranded wire composed of multiple metal wires twisted together. As the material of the core wire 14, for example, copper-based, aluminum-based, or other metal materials can be used.

[0055] The insulating covering portion 15, for example, covers the entire outer periphery of the core wire 14. The insulating covering portion 15 is, for example, made of an insulating material such as synthetic resin. The insulating covering portion 15 is, for example, formed by extrusion molding of the core wire 14.

[0056] The outer casing 13 is generally formed into an elongated cylindrical shape. Multiple wires 12 are inserted into the internal space of the outer casing 13. That is, the outer casing 13 completely surrounds the outer circumference of the multiple wires 12. For example, the outer casing 13 protects each wire 12 from damage by flying objects or water droplets. One end of each wire 12 is connected to the first device M1, and the other end of the wire 12 is connected to the second device M2. The wires 12 are high-voltage wires capable of handling high voltage and high current.

[0057] The outer component 13 is flexible and can be easily bent. Examples of flexible outer components 13 include corrugated pipes made of synthetic resin. The corrugated pipe is formed with a corrugated shape in which the diameter changes repeatedly along its length. That is, the corrugated pipe has concave and convex portions that are alternately connected along its length. Furthermore, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used as the constituent material of the outer component 13.

[0058] like Figure 2 As shown, the wire harness 10 includes a pair of first path limiting members 21, a second path limiting member 31, and a pair of engaging members 51. Furthermore, in Figure 1 The illustrations of the first path limiting member 21, the second path limiting member 31, and the engaging member 51 are omitted.

[0059] Each of the first path limiting member 21 and the second path limiting member 31 is mounted on the outer periphery of the outer component 13. Specifically, the straight portion 11s of the first path limiting member 21, which is a straight section in the path of the wire harness body 11, is mounted on the outer periphery of the outer component 13. The first path limiting member 21 restricts the path of the wire harness body 11 in the straight portion 11s.

[0060] The second path limiting member 31 is installed on the outer periphery of the outer member 13 at the bend 11c of the bend in the path of the wire harness body 11. The second path limiting member 31 restricts the path of the wire harness body 11 in the bend 11c. For example, a first path limiting member 21 is provided for a pair of straight portions 11s provided on both sides of the bend 11c in the path of the wire harness body 11. Each first path limiting member 21 and the second path limiting member 31 assists the outer member 13 so that the wire harness body 11 does not deviate from the predetermined path due to its own weight or other bending.

[0061] (Structure of the first path restriction component 21)

[0062] like Figure 5 As shown, the first path limiting member 21 covers a portion of the circumferential direction of the outer peripheral surface of the outer component 13. For example, the first path limiting member 21 covers more than half of the outer periphery of the outer component 13. In addition, the first path limiting member 21 extends along the length direction of the outer component 13.

[0063] The first path limiting member 21 has a first insertion port 22, which is an opening extending along the length of the first path limiting member 21. Additionally, the first path limiting member 21 has a first end portion 23 and a second end portion 24, which are the two circumferential ends of the first path limiting member 21, forming the first insertion port 22. Furthermore, the first path limiting member 21 has a middle portion 25, which connects the first end portion 23 and the second end portion 24. In other words, the first path limiting member 21 has: a middle portion 25 formed to cover a portion of the circumferential direction of the outer fitting member 13; first end portions 23 and second end portions 24 provided at the two ends of the middle portion 25; and a first insertion port 22 formed through the first end portion 23 and the second end portion 24.

[0064] The first end 23 and the second end 24 are positioned opposite each other in a separated state in the circumferential direction of the first path limiting member 21. Furthermore, the gap between the first end 23 and the second end 24 constitutes the first insertion port 22.

[0065] The first insertion port 22 extends along the length of the first path limiting member 21 and covers its entire length. The opening width of the first insertion port 22, i.e., the shortest distance between the first end 23 and the second end 24, is less than the outer diameter of the outer member 13. The outer member 13 is inserted into the first insertion port 22 in a direction orthogonal to the length of the first path limiting member 21.

[0066] The intermediate portion 25 constitutes the main part of the first path limiting member 21. The cross-sectional shape of the intermediate portion 25 is, for example, arc-shaped. Furthermore, the radial thickness of the intermediate portion 25 is the same in the circumferential direction, for example. Additionally, the cross-sectional shape of the first path limiting member 21 is the same throughout its entire length, for example. Moreover, the central axis C in the cross-section of the intermediate portion 25 is, for example, a straight line. That is, the first path limiting member 21 is formed in a shape that extends linearly in one direction.

[0067] In the cross-section of the first path limiting member 21, the tangent at the first end 23 passing through the central axis C of the intermediate portion 25 is designated as tangent T1, and the tangent at the second end 24 passing through the central axis C is designated as tangent T2. The circumferential dimension θ1 of the first insertion port 22 of the wire harness body 11 is the opening angle of the first insertion port 22 centered on the central axis C, i.e., the angle formed by tangent T1 and tangent T2. The dimension θ1 of the first insertion port 22 is, for example, in the range of 60° to 120°.

[0068] The first path limiting member 21 has protrusions 26 extending from the inner surfaces of the first end 23 and the second end 24, respectively. The cross-sectional shape of each protrusion 26 is, for example, semi-circular. Each protrusion 26 extends, for example, along the length direction of the first path limiting member 21. In addition, each protrusion 26 extends, for example, along the entire length direction of the first path limiting member 21.

[0069] Each protrusion 26 protrudes toward the outer component 13. Each protrusion 26 contacts the outer surface of the outer component 13. Furthermore, each protrusion 26 presses against the outer component 13, for example. The outer component 13 is elastically held between the protrusions 26 and the intermediate portion 25. Thus, the connection between the first path limiting member 21 and the outer component 13 becomes secure. Therefore, the first path limiting member 21, mounted on the outer periphery of the outer component 13, is prevented from moving along the length of the outer component 13.

[0070] Furthermore, when the outer component 13 is inserted into the first path limiting member 21, the opening width of the first insertion port 22 may not return to its original width, i.e., the width when the first path limiting member 21 is not inserted. Specifically, the elastic deformation of the first path limiting member 21 that would otherwise return to its original shape is prevented by the outer component 13, thus the opening width of the first insertion port 22 may sometimes become slightly larger than its original width. Additionally, when the outer component 13 is inserted into the first path limiting member 21, pressing the first path limiting member 21 causes the outer component 13 to flex, thus the opening width of the first insertion port 22 may sometimes return to its original width. In other words, the opening width when the outer component 13 is inserted into the first path limiting member 21 varies depending on the rigidity, flexibility, etc., of the outer component 13 or the first path limiting member 21.

[0071] In the first path limiting member 21, the circumferential tip 23a of the first end 23 and the circumferential tip 24a of the second end 24 are each curved when viewed from the length direction of the first path limiting member 21. In other words, the cross-sectional shape of the tip 23a of the first end 23 and the tip 24a of the second end 24 are formed into a curved shape. Furthermore, the first insertion port 22 is formed by the tip 23a of the first end 23 and the tip 24a of the second end 24. In addition, the protrusion 26 protrudes from the inner surface of the tip 23a of the first end 23 and the tip 24a of the second end 24.

[0072] Furthermore, the material used for the first path limiting member 21 can be, for example, synthetic resins such as polypropylene, polyamide, and polyoxymethylene. The first path limiting member 21 can be formed, for example, by known methods such as extrusion molding and injection molding.

[0073] (Structure of the second path restriction component 31)

[0074] like Figure 2 and Figure 3 As shown, the second path limiting member 31 is mounted on the outer member 13 in the bending portion 11c of the wire harness body 11. The second path limiting member 31 is bent along the shape of the bending portion 11c. Furthermore, as the material of the second path limiting member 31, for example, synthetic resin can be used. The second path limiting member 31 can be formed by known methods such as injection molding.

[0075] The second path limiting member 31 has a main body 32 and a pair of surrounding parts 33.

[0076] The main body 32 extends along the path of the bend 11c of the wire harness body 11. The main body 32 covers a portion of the circumferential direction of the outer peripheral surface of the outer component 13. The main body 32 is, for example, formed in a generally semi-cylindrical shape. That is, the main body 32 covers approximately 180° of the outer periphery of the outer component 13.

[0077] The main body 32 has a third end portion 34 and a fourth end portion 35 as its two circumferential ends. Additionally, the main body 32 has a second insertion port 36 formed through the third end portion 34 and the fourth end portion 35. The second insertion port 36 is an opening between the third end portion 34 and the fourth end portion 35. The second insertion port 36 is an opening extending in the longitudinal direction of the second path limiting member 31. Furthermore, the second insertion port 36 extends along the entire length of the second path limiting member 31. Figure 4As shown, viewed from the opening direction of the second insertion port 36, the third end 34 and the fourth end 35 are bent along the bend 11c of the wire harness body 11. The opening width of the second insertion port 36, i.e., the shortest distance between the third end 34 and the fourth end 35, is equal to or slightly larger than the outer diameter of the outer component 13. The outer component 13 is inserted into the second insertion port 36 in a direction orthogonal to the length direction of the second path limiting member 31.

[0078] like Figure 2 and Figure 3 As shown, the surrounding portions 33 are respectively disposed at both ends of the second path limiting member 31 in the length direction of the wire harness body 11.

[0079] The surrounding portion 33 has an end portion 32a of the main body portion 32 along the length direction of the wire harness body 11 and a cover portion 41. The cover portion 41 is integrally formed with the end portion 32a of the main body portion 32, for example. The cover portion 41 is generally semi-cylindrical, for example. The cover portion 41 covers the second insertion port 36 at the end portion 32a of the main body portion 32. The surrounding portion 33 surrounds the outer periphery of the end portion of the first path limiting member 21 along the length direction by means of the cover portion 41 and the end portion 32a of the main body portion 32.

[0080] The enclosure 33, for example, has a hinge portion 42 that connects the end portion 32a of the main body portion 32 and the cover portion 41. The hinge portion 42 connects one circumferential end of the end portion 32a and one circumferential end of the cover portion 41. A locking portion 43 is provided at the other circumferential end of the end portion 32a. A claw portion 44 is provided at the other circumferential end of the cover portion 41.

[0081] The cover 41 can rotate around the hinge 42 as an axis. Figure 3 The opening position shown is the same as Figure 2 The cover 41 rotates between the shown closed positions. In the closed position, the cover 41 covers the upper opening of the end 32a of the main body 32. Furthermore, when the cover 41 is in the closed position, the claw 44 hooks onto the locking part 43. Thus, the cover 41 remains in the closed position. In this way, the end 32a of the main body 32 and the cover 41 are connected to each other. With the end 32a and the cover 41 connected, the surrounding part 33 forms an annulus that surrounds the outer periphery of the wire harness body 11 and the end of the first path limiting member 21 along its length. In the closed state, the cover 41 covers the first insertion port 22 of the first path limiting member 21.

[0082] like Figure 4 and Figure 5 As shown, the cover portion 41 of the second path limiting member 31 has a through hole 45 that serves as a first engaging portion. The through hole 45 extends through the cover portion 41, for example, radially along the outer member 13. Furthermore, in this embodiment, the cover portion 41 has a single through hole 45. The through hole 45 is, for example, an elongated hole extending circumferentially along the first path limiting member 21.

[0083] (Structure of locking component 51)

[0084] like Figure 5 As shown, the engaging member 51 is disposed within the first insertion port 22. That is, the engaging member 51 can restrict circumferential contact of the member 21 with respect to the first end 23 and the second end 24 constituting the first insertion port 22 in the first path. Furthermore, when the cover 41 is closed, the engaging member 51 is located between the outer peripheral surface of the outer member 13 and the cover 41. The engaging member 51, for example, contacts the outer peripheral surface of the outer member 13. Moreover, the engaging member 51 is, for example, made of synthetic resin.

[0085] In the cross-section of the engaging member 51, which is orthogonal to the central axis C of the intermediate portion 25, the tangent at one circumferential end of the engaging member 51 passing through the central axis C is designated as T3, and the tangent at the other circumferential end of the engaging member 51 passing through the central axis C is designated as T4. The dimension θ2 of the engaging member 51 in the circumferential direction of the wire harness body 11 is the occupancy angle of the engaging member 51 centered on the central axis C, i.e., the angle formed by the tangents T3 and T4. In the circumferential direction of the wire harness body 11, the dimension θ2 of the engaging member 51 is set to be smaller than the dimension θ1 of the first insertion port 22. As a result, the engaging member 51 can move circumferentially within the first insertion port 22 of the wire harness body 11.

[0086] The engaging member 51 has a protrusion 52 that protrudes from the side facing the cover 41 opposite to the closed cover 41. The protrusion 52 extends in a direction orthogonal to the length direction of the wire harness body 11. The protrusion 52 is provided, for example, at the end of the engaging member 51 in the circumferential direction of the first path limiting member 21.

[0087] The protrusion 52 engages with the through hole 45 provided in the cover portion 41. That is, the protrusion 52 is a second engaging portion that engages with the through hole 45, which serves as a first engaging portion. The protrusion 52 can contact the engaging through hole 45 circumferentially relative to the surrounding portion 33. Therefore, in the circumferential direction of the surrounding portion 33, the range of relative movement between the surrounding portion 33 and the engaging member 51 is limited to the range of movement of the protrusion 52 within the through hole 45, which is an elongated hole. Furthermore, the protrusion 52 can contact the engaging through hole 45 in the longitudinal direction of the harness body 11.

[0088] In the cross-section of the protrusion 52 orthogonal to the central axis C of the intermediate portion 25, the tangent at one circumferential end of the protrusion 52 passing through the central axis C is designated as T5, and the tangent at the other circumferential end of the protrusion 52 passing through the central axis C is designated as T6. The dimension θ3 of the circumferential protrusion 52 of the wire harness body 11 is the occupancy angle of the protrusion 52 centered on the central axis C, that is, the angle formed by the tangents T5 and T6.

[0089] On the other hand, in the cross-section of the through hole 45 orthogonal to the central axis C of the intermediate part 25, the tangent at one circumferential end of the through hole 45 passing through the central axis C is designated as T7, and the tangent at the other circumferential end of the through hole 45 passing through the central axis C is designated as T8. The dimension θ4 of the circumferential through hole 45 of the wire harness body 11 is the occupancy angle of the through hole 45 centered on the central axis C, that is, the angle formed by the tangents T7 and T8.

[0090] Furthermore, in the circumferential direction of the wire harness body 11, the size θ4 of the through hole 45 is larger than the size θ3 of the protrusion 52. Therefore, the protrusion 52 can move circumferentially within the through hole 45 of the wire harness body 11. That is, within the area where the protrusion 52 is located within the through hole 45, the engaging member 51 can move relative to the cover 41 in the circumferential direction of the wire harness body 11.

[0091] Furthermore, in this embodiment, the first path limiting member 21 engages with the engaging member 51 circumferentially, but does not engage with the engaging member 51 in the direction along the length of the wire harness body 11. Therefore, with the first path limiting member 21, the second path limiting member 31, and the engaging member 51 installed on the wire harness body 11, the position of the first path limiting member 21 in the length direction of the wire harness body 11 can be adjusted. Moreover, after adjusting the position of the first path limiting member 21 in the length direction of the wire harness body 11, the first path limiting member 21 is fixed to the outer component 13, for example, by a strip-shaped member such as tape or fastening tape. Therefore, when the wire harness 10 is assembled onto the assembly surface A of the vehicle body, the first path limiting member 21 does not shift in the length direction of the wire harness body 11.

[0092] The function of this embodiment will be explained.

[0093] In the path of the wire harness body 11, at the straight section 11s where the first path limiting member 21 is installed, the rigidity of the first path limiting member 21 can suppress the wire harness body 11 from deflecting due to its own weight, etc. Similarly, at the bent section 11c where the second path limiting member 31 is installed, the rigidity of the second path limiting member 31 can suppress the wire harness body 11 from deflecting due to its own weight, etc.

[0094] like Figure 5 As shown, the wiring harness 10 is arranged along the assembly surface A of the vehicle body. Furthermore, the wiring harness 10 is fixed to the assembly surface A by a fixing member (not shown). Additionally, in the path of the wiring harness 10, the fixing point for fixing to the assembly surface A by the fixing member is, for example, set at least one of the first path limiting member 21, the second path limiting member 31, and a location in the outer component 13 where neither the first path limiting member 21 nor the second path limiting member 31 is provided.

[0095] With the wiring harness 10 assembled on the assembly surface A, the cover portion 41 of the surrounding portion 33 is located closer to the assembly surface A than the main body portion 32. When the vehicle V is on the ground, and the assembly surface A is located below the floor of the vehicle V, the assembly surface A faces the ground. Therefore, the main body portion 32 of the second path limiting member 31 is located closer to the ground than the cover portion 41.

[0096] Here, the circumferential position of the first insertion port 22 in the first path limiting member 21 is positioned by the cover 41 and the engaging member 51 that engages with the cover 41. Therefore, the first insertion port 22 is configured to face the cover 41 side, i.e., the assembly surface A side. That is, the first path limiting member 21 covers the ground side of the outer component 13. Thus, the first path limiting member 21 can appropriately protect the outer component 13 from damage such as flying objects or water droplets. This contributes to improving the durability of the wiring harness body 11.

[0097] Furthermore, with the wire harness 10 assembled on the assembly surface A, the main body 32 of the second path limiting member 31 covers the ground side of the outer component 13. Thus, the main body 32 can, for example, adequately protect the outer component 13 from damage by flying objects or water droplets. This contributes to improving the durability of the wire harness body 11.

[0098] The effects of this implementation method will be explained.

[0099] (1) The first path limiting member 21 limits the straight portion 11s in the path of the wire harness body 11. The second path limiting member 31 limits the bent portion 11c in the path of the wire harness body 11. The first path limiting member 21 and the second path limiting member 31 are independent members. Therefore, the position of the first path limiting member 21 relative to the second path limiting member 31 can be adjusted.

[0100] The first insertion port 22 of the first path limiting member 21 is an opening extending along the length of the first path limiting member 21 and extending throughout the entire length of the first path limiting member 21. Therefore, after end processing such as installing a connector at the end of the wire 12 along its length, the first path limiting member 21 can be installed onto the outer component 13 through the first insertion port 22. This allows for the subsequent installation of the first path limiting member 21, thus improving the assembly workability of the wire harness 10.

[0101] A locking member 51, which engages with the second path limiting member 31 in the circumferential direction of the wire harness body 11, is disposed within the first insertion port 22 of the first path limiting member 21. According to this structure, the locking member 51 can be configured to make circumferential contact with the first insertion port 22 of the first path limiting member 21. Thus, the locking member 51 restricts circumferential rotation of the first path limiting member 21, thereby suppressing circumferential rotation of the first path limiting member 21.

[0102] (2) In the circumferential direction of the wire harness body 11, the size θ2 of the engaging member 51 is smaller than the size θ1 of the first insertion port 22. According to this structure, the engaging member 51 can move circumferentially within the first insertion port 22 of the wire harness body 11. Therefore, the relative position of the first path limiting member 21 with respect to the engaging member 51 and the second path limiting member 31 can be adjusted in the circumferential direction of the wire harness body 11.

[0103] (3) In the circumferential direction of the wire harness body 11, the size θ4 of the through hole 45, which serves as the first engaging portion, is larger than the size θ3 of the protrusion 52, which serves as the second engaging portion. According to this structure, within the area where the protrusion 52 is located within the through hole 45, the engaging member 51 can move relative to the cover 41 in the circumferential direction of the wire harness body 11. Therefore, the relative positions of the engaging member 51 and the first path limiting member 21 relative to the second path limiting member 31 can be adjusted in the circumferential direction of the wire harness body 11.

[0104] (4) The second path limiting member 31 has a surrounding portion 33 that surrounds the outer periphery of the first path limiting member 21. The surrounding portion 33 has an end portion 32a of the main body portion 32 of the second path limiting member 31 and a cover portion 41 connected to the end portion 32a. Furthermore, a through hole 45 is provided in the cover portion 41. According to this structure, the surrounding portion 33 divides the main body portion 32 and the cover portion 41, thereby allowing the second path limiting member 31, including the surrounding portion 33, to be subsequently installed on the first path limiting member 21. As a result, the assembly workability of the wire harness 10 can be further improved.

[0105] (5) The main body 32 has a second insertion port 36, which is an opening extending along the length of the second path limiting member 31 and covering the entire length of the second path limiting member 31. Furthermore, the cover 41 covers the second insertion port 36 at the end 32a of the main body 32. Therefore, after end processing such as installing a connector at the end of the wire 12 along its length, the second path limiting member 31 can be installed onto the outer component 13 through the second insertion port 36. This allows for the subsequent installation of the second path limiting member 31, thus further improving the assembly workability of the wire harness 10.

[0106] (6) In the surrounding portion 33, the cover portion 41 is positioned closer to the assembly surface A than the main body portion 32. According to this structure, the through hole 45 of the surrounding portion 33, which engages with the engaging member 51 disposed within the first insertion port 22, is located in the cover portion 41 closer to the assembly surface A. Furthermore, the position of the first insertion port 22 in the circumferential direction of the first path limiting member 21 is positioned by the engaging member 51. That is, according to this structure, the first insertion port 22 of the first path limiting member 21 can be configured to face the cover portion 41 side, i.e., the assembly surface A side. Therefore, it is possible to prevent the first insertion port 22 of the first path limiting member 21 from facing the side opposite to the assembly surface A. As a result, the outer component 13 can be appropriately protected by the first path limiting member 21.

[0107] (7) A first path limiting member 21 is provided on each of the pair of straight portions 11s provided on both sides of the bend portion 11c in the path of the wire harness body 11. In addition, engaging members 51 are respectively provided in the first insertion ports 22 of the pair of first path limiting members 21. According to this structure, the position of each of the first path limiting members 21 arranged on both sides of the second path limiting member 31 can be adjusted in the length direction of the wire harness body 11.

[0108] (8) The first path limiting member 21 has a first end 23 and a second end 24, which are the two circumferential ends of the first path limiting member 21, forming a first insertion port 22. Furthermore, the first path limiting member 21 has a protrusion 26, which protrudes from the inner surfaces of the first end 23 and the second end 24 and contacts the outer surface of the outer component 13. Therefore, the first path limiting member 21 can be appropriately prevented from detaching from the outer component 13 through the first insertion port 22. Thus, the first path limiting member 21 is temporarily fixed to the outer periphery of the outer component 13 by its own protrusion 26, thereby improving workability when the engaging member 51 is placed at the first insertion port 22 of the first path limiting member 21 temporarily fixed to the outer component 13. As a result, the assembly workability of the wire harness 10 can be further improved.

[0109] (9) The protrusion 26 protrudes from the inner surfaces of the top tip 23a of the first end 23 and the top tip 24a of the second end 24. According to this structure, for example, compared to the protrusion 26 protruding from the inner surface at a position slightly away from the top tip 23a of the first end 23 or the top tip 24a of the second end 24, the first path limiting member 21 can be more effectively prevented from disengaging from the outer member 13 through the first insertion port 22.

[0110] (10) The tip 23a of the first end 23 and the tip 24a of the second end 24 are each bent when viewed from the length direction of the first path limiting member 21. Therefore, the outer member 13 can be smoothly inserted into the interior of the first path limiting member 21 through the first insertion port 22 formed by the tips 23a and 24a. In addition, the outer member 13 is less likely to be damaged when it is inserted into the interior of the first path limiting member 21 through the first insertion port 22.

[0111] (11) The cross-sectional shape of the first path limiting member 21 is the same throughout its entire length. With this structure, the first path limiting member 21 can be easily manufactured by using an extrusion molding machine that extrudes the raw material of the first path limiting member 21 in the longitudinal direction. In addition, a variety of first path limiting members 21 with different dimensions in the longitudinal direction can be manufactured using a single extrusion molding machine.

[0112] (12) The protrusion 26 extends along the entire length of the first path limiting member 21. This structure improves the bending stiffness of the first path limiting member 21. Furthermore, the protrusion 26 contacts the outer surface of the outer member 13 along the entire length of the first path limiting member 21. Therefore, extending along the entire length of the first path limiting member 21 prevents it from disengaging from the outer member 13 through the first insertion port 22.

[0113] This embodiment can be implemented in the following variations. This embodiment and the following variations can be combined with each other within the scope of technical non-contradiction.

[0114] The second path limiting member 31 in the above embodiment can also be a structure having multiple through holes 45. In this case, for example... Figure 6 As shown, multiple through holes 45 can also be arranged circumferentially staggered on the main body of the wire harness 11.

[0115] exist Figure 6 In the structure shown, the cover 41 of each of the second path limiting members 31 has, for example, three through holes 45. The three through holes 45 are arranged offset from each other in the longitudinal direction of the wire harness body 11. The center positions of each through hole 45 in the circumferential direction of the wire harness body 11 are offset from each other in the same circumferential direction. In addition, regarding the projection of each through hole 45 in the longitudinal direction of the wire harness body 11, the projections of adjacent through holes 45 in the longitudinal direction of the wire harness body 11 overlap with each other.

[0116] According to this structure, the orientation of the first path limiting member 21 in the circumferential direction of the wire harness body 11 can be changed. In detail, the orientation of the first path limiting member 21 in the circumferential direction of the wire harness body 11 changes depending on which of the plurality of through holes 45 the protrusion 52 of the engaging member 51 engages with.

[0117] like Figure 6 As shown, the three through holes 45 are sequentially designated as through hole 45a, through hole 45b and through hole 45c in the circumferential direction of the surrounding portion 33, starting from the side closest to the hinge portion 42.

[0118] exist Figure 6 and Figure 7 In the shown state, in each engaging member 51, the protrusion 52 engages with the through hole 45a. In this state, the opening direction of the first insertion port 22 of the first path limiting member 21 is in the same direction as the opening direction of the second insertion port 36 of the second path limiting member 31.

[0119] On the other hand, Figure 8 and Figure 9 In the shown state, in one of the engaging members 51, the protrusion 52 engages with the through hole 45b. In this state, the opening direction of the first insertion port 22 in one of the first path limiting members 21 becomes the same as the opening direction of the second insertion port 36 in the second path limiting member 31.

[0120] Thus, according to this structure, the first path limiting member 21 can be positioned circumferentially relative to the second path limiting member 31, and the circumferential orientation of the first path limiting member 21 can be changed. Therefore, the circumferential orientation of the first path limiting member 21 can be changed according to the bending path of the wire harness body 11, with the first insertion port 22 facing the assembly surface A. As a result, this increases the degree of freedom in the layout of the wire harness 10.

[0121] Furthermore, the configuration and number of multiple through holes 45 are not limited to Figure 6 The structure shown can be appropriately deformed. For example, the through holes 45 can be arranged such that the projections of the through holes 45 along the length direction of the wire harness body 11 do not overlap.

[0122] Alternatively, the engaging member 51 may have a protrusion protruding from the surface opposite to the outer member 13, and this protrusion may engage with the recess of the bellows, which is the outer member 13. With this structure, the protrusion of the engaging member 51 engages with the recess of the bellows along the length of the bellows. Therefore, the engaging member 51 and the outer member 13 are less likely to move relative to each other along the length of the outer member 13.

[0123] In the above embodiment, the protrusion 52 is provided at the end of the engaging member 51 in the circumferential direction of the first path limiting member 21. However, in addition, for example, the protrusion 52 may also be provided at the central part of the engaging member 51 in the circumferential direction of the first path limiting member 21.

[0124] Alternatively, the size θ4 of the through hole 45, which serves as the first engaging part, can be approximately equal to the size θ3 of the protrusion 52, which serves as the second engaging part, in the circumferential direction of the wire harness body 11.

[0125] Alternatively, the size θ2 of the engaging member 51 can be made approximately equal to the size θ1 of the first insertion port 22 in the circumferential direction of the wire harness body 11.

[0126] In the above embodiment, a through hole 45, which serves as the first engaging portion that engages with the protrusion 52 of the engaging member 51, is provided in the cover portion 41 of the surrounding portion 33. However, it is not limited to this, and the through hole 45 may also be provided at, for example, the end portion 32a of the main body portion 32. According to this structure, the first path limiting member 21 can be circumferentially positioned at the position of the first insertion port 22 facing the end portion 32a of the main body portion 32.

[0127] In the above embodiment, the first engaging portion that engages with the protrusion 52, which is the second engaging portion, is set as a through hole 45 that penetrates the cover portion 41. However, in other cases, the first engaging portion may be set as a recess that does not penetrate the cover portion 41.

[0128] In the above embodiment, the first engaging portion of the second path limiting member 31 is configured as a through hole 45, and the second engaging portion of the engaging member 51 is configured as a protrusion 52, with the first and second engaging portions fitting together in a concave-convex manner. However, the concave-convex relationship can also be reversed. In this case, the second path limiting member 31, for example, has a protrusion that protrudes from the cover portion 41 toward the engaging member 51 as the first engaging portion. Furthermore, the engaging member 51 has a recess that fits into the protrusion of the first engaging portion as the second engaging portion. According to this structure, approximately the same effect as in the above embodiment can be obtained.

[0129] In the enclosure portion 33 of the above embodiment, the end portion 32a of the main body portion 32 and the cover portion 41 are formed as one piece, but it is not particularly limited to this, and the end portion 32a of the main body portion 32 and the cover portion 41 can also be separated.

[0130] In the above embodiment, the protrusion 26 protrudes from the tip 23a of the first end portion 23. However, it is not limited to this; the protrusion 26 may also be positioned in the circumferential direction of the first path limiting member 21 at a location farther from the first insertion port 22 than the tip 23a of the first end portion 23. Similarly, in the above embodiment, the protrusion 26 protrudes from the tip 24a of the second end portion 24. However, it is not limited to this; the protrusion 26 may also be positioned in the circumferential direction of the first path limiting member 21 at a location farther from the first insertion port 22 than the tip 24a of the second end portion 24.

[0131] Alternatively, the protrusion 26 may be partially provided in the length direction of the first path limiting member 21.

[0132] Alternatively, at least one of the protrusions 26 of the first end 23 and the second end 24 may be omitted from the first path limiting member 21.

[0133] Alternatively, a second protrusion can be provided in the first path limiting member 21, protruding from the inner surface of the middle portion 25 and contacting the outer surface of the outer member 13. According to this structure, both the protrusion 26 and the second protrusion can contact the outer surface of the outer member 13, thereby suppressing the swaying of the first path limiting member 21.

[0134] Alternatively, in the first path limiting member 21, a groove extending along the length direction can be provided on the outer peripheral surface of the intermediate portion 25. With this structure, the intermediate portion 25 can easily deform outwards from the groove, thereby easily enlarging the first insertion port 22. As a result, this contributes to improving the assemblability of the first path limiting member 21.

[0135] Alternatively, the radial thickness of the middle portion 25 in the first path limiting member 21 may change in the circumferential direction.

[0136] The shape of the middle portion 25 in the first path limiting member 21 is not limited to an arc shape; for example, it can be changed to an elliptical arc shape. Similarly, the shape of the inner circumferential surface of the second path limiting member 31 is not limited to an arc shape; for example, it can be changed to an elliptical arc shape.

[0137] In the above embodiments, the outer component 13 may also be configured to have a slit extending along the length direction, and the first path limiting component 21 may be fixed to the slit.

[0138] The number of second path limiting members 31 provided on the wire harness 10 is appropriately determined according to the path of the wire harness body 11, and the number of second path limiting members 31 is one or more.

[0139] In the above embodiment, the first path limiting member 21 is respectively disposed on both sides of the second path limiting member 31 in the length direction of the wire harness body 11. However, it is also possible that the first path limiting member 21 is disposed only on one side of the second path limiting member 31 in the same length direction.

[0140] In the above embodiment, the wire 12 is configured as a high-voltage wire, but it is not limited to this. For example, the wire 12 can also be configured as a low-voltage wire.

[0141] The embodiments and variations disclosed herein should be considered illustrative in all respects and not restrictive. The scope of the invention is not as described above, but is set forth by the claims and is intended to include all variations within the meaning and scope equivalent to the claims.

[0142] like Figure 2 and Figure 5 As shown, the engaging member 51 can also be a plate-shaped member that is curved in an arc shape when viewed from the length direction of the wire harness body 11. Furthermore, in the closed state of the cover 41, the outer surface of the engaging member 51 can be tightly fitted by the inner surface of the cover 41. Additionally, in the closed state of the cover 41, the inner surface of the engaging member 51 can also be tightly fitted with the outer surface of the outer component 13. Figure 5 As shown, when the cover 41 is closed, the top of the protrusion 52 protrudes radially outward from the outer surface of the cover 41.

[0143] like Figure 5 As shown, the top tip 23a of the first end 23 and the top tip 24a of the second end 24 of the first path limiting member 21 may also be opposite to the two circumferential ends of the engaging member 51. Alternatively, when the engaging member 51 is disposed in the first insertion port 22 and the first path limiting member 21 is surrounded by the surrounding portion 33, circumferential gaps may be formed between the first end 23 and the engaging member 51 and between the second end 24 and the engaging member 51.

[0144] like Figure 4 As shown, the width of the engaging member 51 along the length of the wire harness body 11 can also be smaller than the width of the surrounding portion 33 along the length of the wire harness body 11, such as... Figure 6 As shown, the length-direction width of the engaging member 51 may also be greater than the length-direction width of the surrounding portion 33. Furthermore, sometimes the dimension θ2 of the engaging member 51 is used as a reference for the circumferential width of the engaging member 51. Similarly, sometimes the dimension θ1 of the first insertion port 22 is used as a reference for the circumferential width of the first insertion port 22, the dimension θ3 of the protrusion 52 is used as a reference for the circumferential width of the protrusion 52, and the dimension θ4 of the through hole 45 is used as a reference for the circumferential width of the through hole 45.

[0145] like Figure 5As shown, viewed from the length direction of the first path limiting member 21, the surface of the tip 23a of the first end 23 can also be a smooth, continuous arc shape with the surface of the protrusion 26 of the first end 23. In other words, viewed from the length direction of the first path limiting member 21, the tip 23a of the first end 23 and the protrusion 26 can also have arc-shaped surfaces extending on the same circumference. Similarly, the surface of the tip 24a of the second end 24 can also be a smooth, continuous arc shape with the surface of the protrusion 26 of the second end 24. In other words, viewed from the length direction of the first path limiting member 21, the tip 24a of the second end 24 and the protrusion 26 can also have arc-shaped surfaces extending on the same circumference. Furthermore, sometimes the first end 23 is referred to as the first edge, and the second end 24 as the second edge. Additionally, sometimes the protrusion 26 of the first end 23 is referred to as the first protrusion, and the protrusion 26 of the second end 24 as the second protrusion.

[0146] like Figure 2 As shown, the first insertion port 22 can also be a first groove that extends linearly along the length of the first path limiting member 21 and covers the entire length of the first path limiting member 21, with openings at both ends in the length direction of the first path limiting member 21. Figure 2 and Figure 5 As shown, it is also possible that, with the engaging member 51 disposed within the first insertion port 22 and the first path limiting member 21 surrounded by the surrounding portion 33, the first insertion port 22 is entirely oriented toward the side where the assembly surface A is provided, for example, the side opposite to the ground. Sometimes the first path limiting member 21 is referred to as a first path defining member that defines the path of the straight portion 11s of the wire harness body 11.

[0147] like Figure 2 As shown, the second insertion port 36 can also be a second groove bent along the length direction of the second path limiting member 31, with openings at both ends of the second path limiting member 31 along its length. Figure 2 and Figure 5 As shown, the second insertion port 36 may also be positioned such that, with the wire harness 10 assembled on the assembly surface A, the entire second insertion port 36 faces the side where the assembly surface A is located, for example, the side opposite to the ground. Sometimes, the second path limiting member 31 is referred to as a second path defining member that defines the path of the bending portion 11c of the wire harness body 11.

[0148] like Figure 4 and Figure 5 As shown, the end of the first path limiting member 21 in the length direction can also be inserted into the second insertion port 36.

[0149] This disclosure includes the following installation examples. Reference numerals are used to indicate several constituent elements of the illustrated embodiments, not for limitation, but as an aid to understanding. Some of the items described in the following installation examples may be omitted, or several items described in the installation examples may be selected or combined.

[0150] [Note 1] In one embodiment of this disclosure, the engaging member (51) may also be a plate-shaped member that is curved in an arc shape when viewed from the length direction of the wire harness body (11).

[0151] When the cover (41) is closed, the outer surface of the engaging member (51) is in close contact with the inner surface of the cover (41).

[0152] The inner surface of the engaging member (51) is in close contact with the outer surface of the outer component (13).

[0153] [Note 2] In one aspect of this disclosure, the protrusion (26) protrudes from the inner surfaces of the top ends of the first end (23) and the second end (24), respectively.

[0154] Viewed from the length direction of the first path limiting member (21),

[0155] The surface of the top end (23a) of the first end (23) can also be a smooth, continuous arc shape with the surface of the protrusion (26) of the first end (23).

[0156] The surface of the top end (24a) of the second end (24) may also be a smooth, continuous arc shape with the surface of the protrusion (26) of the second end (24).
