[0022] [Description of embodiments of this disclosure]

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

[0024] The wire harness configuration disclosed herein is as follows:

[0025] [1] A wiring harness, installed in a vehicle body, wherein the wiring harness comprises: a wiring harness body having wires and an outer casing covering the wires; a first path limiting member installed on the outer periphery of the outer casing to limit the path of a straight portion that is a straight section in the path of the wiring harness body; a second path limiting member installed on the outer periphery of the outer casing to limit the path of a bent portion that is a bent section in the path of the wiring harness body; and a connecting member having an annular shape surrounding the outer casing and the second path limiting member to connect the outer casing and the wires. The second path limiting components are interconnected. The second path limiting component has a first engaging portion, which is either a protrusion extending radially along the outer component or a recessed portion recessed radially along the outer component. The connecting component has a second engaging portion that engages with the first engaging portion. The first path limiting component has an insertion port, which is an opening extending along the length of the first path limiting component and throughout its entire length. The first path limiting component is arranged with the second path limiting component along the length of the wire harness body.

[0026] According to this structure, the wire harness includes a first path limiting member that limits straight portions in the path of the wire harness body and a second path limiting member that limits bent portions in the path of the wire harness body. Furthermore, the first path limiting member and the second path limiting member are arranged in a symmetrical configuration along the length of the wire harness body. Therefore, the position of the first path limiting member relative to the second path limiting member can be adjusted.

[0027] Furthermore, according to this structure, the second path limiting member has a first engaging portion, which is either a protrusion extending radially along the outer component or a recess recessing radially along the outer component. Moreover, the connecting member has a second engaging portion that engages with the first engaging portion. Thus, the connecting member can be securely connected to the second path limiting member.

[0028] 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 termination processing such as mounting the connector to the end of the wire along its length, the first path limiting member can be installed onto the outer component through the insertion port. This allows for the subsequent installation of the first path limiting member, thus improving the ease of wire harness assembly.

[0029] [2] The connecting member is configured to span across the first path limiting member and the second path limiting member in the length direction of the wire harness body, and the connecting member surrounds a portion of the outer periphery of the first path limiting member in the length direction. According to this structure, the gap between the first path limiting member and the second path limiting member mounted on the outer periphery of the outer component can be covered by the connecting member.

[0030] [3] The connecting member has a protrusion that protrudes toward the insertion port and is located within the insertion port.

[0031] According to this structure, the protrusion of the connecting member can be configured to contact the insertion port of the first path limiting member in the circumferential direction. Therefore, the protrusion of the connecting member restricts the circumferential rotation of the first path limiting member, thus suppressing circumferential rotation of the first path limiting member.

[0032] [4] The connecting member has a main body and a cover connected to the main body, and the connecting member is in a ring shape surrounding the outer periphery of the outer component and the second path limiting component when the main body and the cover are connected.

[0033] According to this structure, although the connecting component is designed as a ring, by dividing the connecting component into a main body and a cover, the connecting component can be subsequently installed on the outer component and the second path limiting component. This further improves the ease of assembly of the wire harness.

[0034] [5] The vehicle body has an assembly surface for assembling the main body of the wiring harness, the cover is configured to be closer to the assembly surface than the main body, and the protrusion is provided on the cover.

[0035] According to this structure, in the connecting member, the protrusion located within the insertion port of the first path limiting member is positioned on the cover portion closer to the assembly surface of the vehicle body. Furthermore, the circumferential insertion port of the first path limiting member is positioned by the protrusion of the connecting 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 connecting 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.

[0036] [6] The outer component is a corrugated tube with alternating concave and convex portions connected along the length of the outer component, and the connecting component has a second protrusion that protrudes from the first protrusion as a first protrusion, the second protrusion engaging with the concave portion of the corrugated tube.

[0037] According to this structure, the second protrusion of the connecting member engages with the recess of the bellows along its length. This suppresses relative movement of the bellows with respect to the connecting member along its length. In other words, the connecting member is positioned relative to the bellows along its length. Therefore, during wire harness assembly, the position of the first path limiting member relative to the second path limiting member can be adjusted while the position of the connecting member relative to the bellows is fixed.

[0038] [7] The outer component is a corrugated tube with alternating concave and convex portions connected along the length of the outer component. The first engaging portion is a through hole formed radially along the outer component. The second engaging portion is a third protrusion that engages with the through hole. The connecting component has a fourth protrusion that protrudes from the third protrusion and engages with the concave portion of the corrugated tube.

[0039] According to this structure, the fourth protrusion of the connecting member engages with the recess of the bellows along its length. This suppresses relative movement of the bellows with respect to the connecting member along its length. In other words, the connecting member is positioned relative to the bellows along its length. Therefore, during wire harness assembly, the position of the first path limiting member relative to the second path limiting member can be adjusted while the position of the connecting member relative to the bellows is fixed.

[0040] [8] The first engaging part has a plurality of parts arranged in the circumferential direction of the second path limiting part.

[0041] According to this structure, it is possible to select which of the multiple first engaging portions provided circumferentially in the second path limiting member the second engaging portion of the connecting 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.

[0042] [9] The insertion port in the first path limiting component is used as the first insertion port, and the second path limiting component has a second insertion port, which is an opening that extends along the length of the second path limiting component and throughout the entire length of the second path limiting component.

[0043] According to this structure, the second insertion port is an opening extending along the length of the second path limiting member and extending throughout the entire length of the second path limiting member. Therefore, after termination processing such as mounting the connector to the end of the wire along its length, the second path limiting member can be installed onto the outer component through the insertion port. This allows for the subsequent installation of the second path limiting member, thus improving the ease of wire harness assembly.

[0044]

[10] The first path limiting member is provided on a pair of straight sections on both sides of the bend in the path of the wire harness body, and the connecting member is provided at both ends of the second path limiting member in the length direction of the wire harness body.

[0045] According to this structure, each first path limiting member, disposed on both sides of the second path limiting member along the length of the wire harness body, is arranged in a manner parallel to the second path limiting member along the length of the wire harness body. Therefore, the position of each first path limiting member relative to the second path limiting member can be adjusted.

[0046]

[11] The first path limiting member has: a first end and a second end, the first end and the second end being two circumferential ends of the first path limiting member and forming the insertion port; and a contact portion 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.

[0047] According to this structure, the first path limiting member has a contact portion 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, it is possible to appropriately prevent the first path limiting member from detaching from the outer component through the insertion port.

[0048]

[12] The contact portion protrudes from the inner surface of the front end of at least one of the front end of the first end and the front end of the second end.

[0049] According to this structure, for example, compared to the case where the contact portion protrudes from the inner surface at a position slightly separated from the front end of the first end and the front end of the second end portion, it is possible to more effectively prevent the path limiting member from detaching from the outer component through the insertion port.

[0050] [Details of the embodiments disclosed herein]

[0051] Hereinafter, specific examples of the wire harness of this disclosure will be described with reference to the accompanying drawings. In the drawings, for ease of explanation, sometimes a portion of the structure is shown exaggeratedly or simplified. Additionally, the dimensional ratios of the parts may differ in different drawings. Furthermore, the term "orthogonal" in this specification includes not only strictly orthogonal cases but also cases where they 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 refers to the invention as set forth in the claims, and is intended to include all modifications with the same meaning and scope as the claims.

[0052] Furthermore, the term "cylindrical" as used in this specification includes not only shapes with a continuous circumferential wall, but also shapes formed by combining multiple components into a cylindrical shape, and shapes such as a C-shape with a slit in a portion of the circumference. Additionally, the shape of "cylindrical" includes circles, ellipses, and polygons with sharp or rounded corners. Furthermore, the term "ring-shaped" as used in this specification sometimes refers to any structure forming a ring, a continuous shape without ends, and a typical ring shape with gaps, such as a C-shape. Additionally, the shape of "ring-shaped" includes circles, ellipses, and polygons with sharp or rounded corners, but is not limited to these.

[0053] (Overall structure of wire harness 10)

[0054] 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 the middle portion of the wiring harness 10 in the longitudinal direction passes through the exterior of the vehicle V, such as under the floor.

[0055] 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 at the rear of the vehicle V, and the second device M2 is an inverter disposed at 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 more. The second device M2, as an inverter, is connected to a motor (not shown) for driving the wheels, which serves as the power source for the vehicle's movement. The inverter generates alternating current from the direct current (DC) power of the high-voltage battery and supplies this AC power to the motor. The wiring harness body 11 is laid along a path that is curved in a two-dimensional or three-dimensional manner.

[0056] (Structure of wire harness body 11)

[0057] like Figure 5 and Figure 6 As shown, the main body 11 of the wiring harness has wires 12 and external components 13. For example, multiple wires 12 are provided.

[0058] like Figure 6 As shown, the wire 12 is, for example, a sheathed wire. That is, the wire 12 has a core wire 14 and an insulating covering 15 that covers the outer periphery of the core wire 14. The core wire 14 is, for example, made of a flexible conductor that can be easily bent. Another example of such a flexible conductor is a stranded wire made of multiple metal wires twisted together. As the material of the core wire 14, for example, copper-based, aluminum-based, and other metal materials can be used.

[0059] The insulating covering portion 15, for example, covers the entire circumference of the 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 can be formed, for example, by extrusion molding of the core wire 14.

[0060] like Figure 5 and Figure 6 As shown, the outer casing 13 is generally elongated and cylindrical. Multiple wires 12 are inserted into the internal space of the outer casing 13. That is, the outer casing 13 surrounds the outer perimeter of the multiple wires 12. The outer casing 13, for example, protects each wire 12 from flying objects and 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.

[0061] The outer component 13 is, for example, made of a corrugated tube of synthetic resin. The corrugated outer component 13 has a corrugated shape with a diameter that repeats in its length direction. That is, the outer component 13 has recesses 13a and protrusions 13b alternately connected in the length direction of the outer component 13. The recesses 13a and protrusions 13b are, for example, annular, extending around the circumference of the outer component 13. The corrugated outer component 13 is flexible and can be easily bent. Furthermore, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used as the constituent material of the outer component 13.

[0062] like Figure 2 As shown, the wiring harness 10 includes a pair of first path limiting members 21, a second path limiting member 31, and a pair of connecting members 41. Additionally, Figure 1 The illustrations of the first path limiting component 21, the second path limiting component 31, and the connecting component 41 are omitted.

[0063] Each of the first path limiting components 21 and the second path limiting component 31 is mounted on the outer periphery of the outer component 13. Specifically, the straight portion 11s of the first path limiting component 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 component 21 restricts the path of the wire harness body 11 at the straight portion 11s.

[0064] The second path limiting member 31 is mounted on the outer periphery of the outer component 13 at the bend 11c, which is a 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 at the bend 11c. The first path limiting member 21 is provided, for example, on a pair of straight portions 11s on both sides of the bend 11c in the path of the wire harness body 11. Each of the first path limiting member 21 and the second path limiting member 31 assists the outer component 13 so that the wire harness body 11 does not detach from the predetermined path due to its own weight or other bending.

[0065] (Structure of the first path limiting component 21)

[0066] like Figure 6 As shown, the first path limiting member 21 covers a portion of the circumferential surface of the outer peripheral surface of the outer component 13. For example, the first path limiting member 21 covers a range greater than 180° on 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.

[0067] The first path limiting member 21 has a first insertion port 22 extending along the length direction of the first path limiting member 21. Furthermore, the first path limiting member 21 has a first end portion 23 and a second end portion 24 forming the first insertion port 22 at both circumferential ends of the first path limiting member 21. Additionally, the first path limiting member 21 has a middle portion 25 connecting 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; a first end portion 23 and a second end portion 24 disposed at both ends of the middle portion 25; and a first insertion port 22 formed by the first end portion 23 and the second end portion 24.

[0068] 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. Moreover, the gap between the first end 23 and the second end 24 constitutes a first insertion port 22.

[0069] 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 smaller than the outer diameter of the outer component 13. The outer component 13 is inserted into the first insertion port 22 in a direction orthogonal to the length of the first path limiting member 21.

[0070] 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, for example, the same in the circumferential direction. Additionally, the cross-sectional shape of the first path limiting member 21 is, for example, the same throughout its entire length. Furthermore, 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 to extend linearly in one direction.

[0071] In the cross-section of the first path limiting member 21, the tangent line passing through the first end 23 of the central axis C of the intermediate portion 25 is designated as tangent line T1, and the tangent line passing through the second end 24 of the central axis C is designated as tangent line T2. The opening angle θ of the first insertion port 22 in the circumferential direction of the first path limiting member 21 is, for example, in the range of 60° to 120°. In addition, the opening angle θ of the first insertion port 22 is the angle centered on the central axis C of the intermediate portion 25, that is, the angle formed by tangent line T1 and tangent line T2.

[0072] The first path limiting member 21 has contact portions 26 protruding from the inner surfaces of the first end 23 and the second end 24, respectively. The cross-sectional shape of each contact portion 26 is, for example, semi-circular. Each contact portion 26 extends, for example, along the length direction of the first path limiting member 21. Furthermore, each contact portion 26 extends, for example, along the entire length of the first path limiting member 21.

[0073] Each contact portion 26 protrudes toward the outer component 13. Each contact portion 26 contacts the outer surface of the outer component 13. Moreover, each contact portion 26 presses against the outer component 13, for example. The outer component 13 is elastically held by each contact portion 26 and the intermediate portion 25. As a result, the connection between the first path limiting member 21 and the outer component 13 becomes secure. Therefore, movement of the first path limiting member 21, which is mounted on the outer periphery of the outer component 13, in the longitudinal direction of the outer component 13 is suppressed.

[0074] Furthermore, when the outer component 13 is inserted into the first path limiting component 21, the opening width of the first insertion port 22 does not necessarily return to its original width, i.e., the width of the first path limiting component 21 when it is not inserted. Specifically, the elastic deformation of the first path limiting component 21 to return to its original shape is hindered by the outer component 13, thus the opening width of the first insertion port 22 sometimes becomes slightly larger than its original width. Additionally, when the outer component 13 is inserted into the first path limiting component 21, the outer component 13 becomes flexed due to the pressure of the first path limiting component 21, thus the opening width of the first insertion port 22 sometimes returns to its original width. In other words, the opening width when the outer component 13 is inserted into the first path limiting component 21 is determined by the rigidity and flexibility of the outer component 13 and the first path limiting component 21.

[0075] In the first path limiting member 21, when viewed from the length direction of the first path limiting member 21, the circumferential front end 23a of the first end 23 and the circumferential front end 24a of the second end 24 are respectively curved. In other words, the cross-sectional shape of the front end 23a of the first end 23 and the front end 24a of the second end 24 is curved. In addition, the first insertion port 22 is formed by the front end 23a of the first end 23 and the front end 24a of the second end 24. Furthermore, the contact portion 26 protrudes from the inner surface of the front end 23a of the first end 23 and the front end 24a of the second end 24.

[0076] Furthermore, the material used for the first path limiting component 21 can be, for example, synthetic resins such as polypropylene, polyamide, and polyoxymethylene. The first path limiting component 21 can be formed, for example, by known methods such as extrusion molding and injection molding.

[0077] (Structure of the second path limiting component 31)

[0078] like Figure 3 As shown, the second path limiting member 31 is installed on the outer component 13 at the bend 11c of the wire harness body 11. The second path limiting member 31 is bent along the shape of the bend 11c.

[0079] like Figure 7 As shown, the second path limiting member 31 covers a portion of the circumferential surface of the outer peripheral surface of the outer component 13. The second path limiting member 31 is, for example, generally semi-cylindrical. That is, the second path limiting member 31 covers approximately 180° of the outer periphery of the outer component 13. In addition, the second path limiting member 31 extends along the shape of the bend 11c of the wire harness body 11.

[0080] The second path limiting member 31 has a third end 32 and a fourth end 33 as its two circumferential ends. Additionally, the second path limiting member 31 has a second insertion port 34 formed by the third end 32 and the fourth end 33. The second insertion port 34 is an opening between the third end 32 and the fourth end 33. The second insertion port 34 is an opening formed along the length direction of the second path limiting member 31. Furthermore, the second insertion port 34 extends along the entire length of the second path limiting member 31. Figure 4 As shown, for example, when viewed from the opening direction of the second insertion port 34, the third end 32 and the fourth end 33 are bent along the bending portion 11c of the wire harness body 11.

[0081] The opening width of the second insertion port 34, i.e., the shortest distance between the third end 32 and the fourth end 33, 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 34 in a direction orthogonal to the length direction of the second path limiting component 31.

[0082] like Figure 3 and Figure 7 As shown, the second path limiting member 31 has a through hole 35 that serves as a first engaging portion. The through hole 35 extends radially through the second path limiting member 31 along the outer mounting member 13. The second path limiting member 31 may have, for example, multiple through holes 35. Figure 3 As shown, the through holes 35 are arranged in two rows along the length direction of the second path limiting member 31, and in three rows along the circumference of the second path limiting member 31. That is, there are six through holes 35. In addition, in the second path limiting member 31 of this embodiment, the through hole groups 35G formed by the six through holes 35 are respectively arranged near the two ends of the second path limiting member 31 in the length direction.

[0083] Furthermore, synthetic resin can be used as the material for the second path limiting member 31. The second path limiting member 31 can be formed, for example, by a known method such as injection molding.

[0084] like Figure 2 and Figure 4 As shown, the first path limiting members 21 are respectively disposed on both sides of the second path limiting member 31 along the length direction of the wire harness body 11. Each first path limiting member 21 is disposed separately from the second path limiting member 31 along the length direction of the wire harness body 11. Each first path limiting member 21 is arranged relative to the second path limiting member 31, for example, through a small gap.

[0085] (Structure of connecting component 41)

[0086] Connecting components 41 are respectively disposed at both ends of the second path limiting component 31 along the length of the wire harness body 11. Each connecting component 41 connects the outer component 13 to the second path limiting component 31. In addition, each connecting component 41 is configured to span across the end of the second path limiting component 31 and the end of the first path limiting component 21 along the length of the wire harness body 11.

[0087] like Figure 3 and Figure 6 As shown, the connecting member 41 has a main body portion 42 and a cover portion 43 connected to the main body portion 42. The main body portion 42 and the cover portion 43 are integrally formed, for example. Furthermore, synthetic resin can be used as the material for the connecting member 41, for example. The connecting member 41 can be formed, for example, by a known method such as injection molding.

[0088] The main body 42 is, for example, generally semi-cylindrical. The main body 42 covers approximately half of the circumferential portion at the end of the second path limiting member 31 along its length. Additionally, the cover 43 is, for example, generally semi-cylindrical with the same dimensions as the main body 42. The main body 42 and the cover 43 cover the entire circumference at the end of the second path limiting member 31 along its length.

[0089] The connecting member 41 has, for example, a hinge portion 44 that connects the main body portion 42 and the cover portion 43. The hinge portion 44 connects one circumferential end of the main body portion 42 and one circumferential end of the cover portion 43. A locking portion 45 is provided at the other circumferential end of the main body portion 42. A claw portion 46 is provided at the other circumferential end of the cover portion 43.

[0090] The cover 43 can rotate around the hinge 44. Figure 3 The opening position shown is the same as Figure 2 The cover 43 rotates between the shown closed positions. In the closed position, the cover 43 covers the upper opening of the main body 42. Furthermore, when the cover 43 is in the closed position, the claw 46 hooks onto the locking part 45. Thus, the cover 43 remains in the closed position. In this way, the main body 42 and the cover 43 are connected to each other. With the main body 42 and the cover 43 connected, the connecting member 41 forms a ring surrounding the outer periphery of the wire harness body 11. The connecting member 41 also surrounds the outer component 13 and the longitudinal end of the second path limiting member 31. That is, the connecting member 41 connects the second path limiting member 31 to the outer component 13 in a manner that prevents the second path limiting member 31 from detaching from the outer component 13.

[0091] Furthermore, the connecting member 41 surrounds the outer periphery of the end of the first path limiting member 21 along its length. The connecting member 41 is disposed along the length of the harness body 11 at the portion where the end of the second path limiting member 31 faces the end of the first path limiting member 21. That is, the connecting member 41 covers the outer periphery of the gap between the first path limiting member 21 and the second path limiting member 31. Additionally, for example, the cover 43 covers the first insertion port 22 of the first path limiting member 21 in its closed state when connected to the body 42.

[0092] like Figure 3 , Figure 5 as well as Figure 6 As shown, each connecting member 41 has a first protrusion 51 protruding from the inner circumferential surface of the cover portion 43. The first protrusion 51 is provided in the connecting member 41 at the portion surrounding the first path limiting member 21. The first protrusion 51 protrudes in a direction orthogonal to the length direction of the wire harness body 11. The first protrusion 51 protrudes toward the first insertion port 22 and is located within the first insertion port 22. That is, the first protrusion 51 can contact the first end portion 23 and the second end portion 24 constituting the first insertion port 22 in the circumferential direction of the first path limiting member 21. Thus, the first protrusion 51 restricts the first path limiting member 21 from rotating in the circumferential direction.

[0093] Furthermore, in this embodiment, the first path limiting member 21 engages with the connecting member 41 in the circumferential direction via the first protrusion 51, but does not engage in the direction along the length of the wiring harness body 11. Therefore, with the first path limiting member 21, the second path limiting member 31, and the connecting member 41 installed on the wiring harness body 11, the position of the first path limiting member 21 in the length direction of the wiring harness body 11 can be adjusted. After adjusting the position of the first path limiting member 21 in the length direction of the wiring harness body 11, the first path limiting member 21 is fixed to the outer component 13, for example, by a strip-shaped component such as adhesive tape or fastening tape. Therefore, when the wiring harness 10 is assembled onto the assembly surface A of the vehicle body, the first path limiting member 21 will not shift in the length direction of the wiring harness body 11.

[0094] Each connecting member 41 has a second protrusion 52 that protrudes further inward from the front end of the first protrusion 51. The front end of the second protrusion 52 is, for example, arc-shaped along the outer periphery of the outer member 13. For example, multiple second protrusions 52 are provided. The multiple second protrusions 52 are arranged in the longitudinal direction of the outer member 13. The multiple second protrusions 52 respectively engage with multiple recesses 13a of the outer member 13. Thus, each second protrusion 52 engages with the recess 13a in the longitudinal direction of the outer member 13. Therefore, it is difficult for the connecting member 41 and the outer member 13 to move relative to each other in the longitudinal direction of the outer member 13.

[0095] like Figure 3 , Figure 5 as well as Figure 7 As shown, each connecting member 41 has a third protrusion 53 protruding from the inner peripheral surface of the main body 42. The third protrusion 53 is provided in the part of the main body 42 that covers the second path limiting member 31. The third protrusion 53 extends in a direction orthogonal to the length direction of the wire harness body 11.

[0096] For example, two third protrusions 53 are provided along the length direction of the wire harness body 11. Each third protrusion 53 engages with a through hole 35 provided in the second path limiting member 31. That is, each third protrusion 53 is a second engaging part that engages with the through hole 35, which serves as a first engaging part. Each third protrusion 53 can contact the through hole 35 to be engaged in the second path limiting member 31 in both the circumferential and length directions. In other words, by the engagement of each third protrusion 53 with the through hole 35, the second path limiting member 31 and the connecting member 41 cannot move relative to each other in the circumferential and length directions of the second path limiting member 31.

[0097] Each connecting member 41 has a fourth protrusion 54 that protrudes further inward from the front end of each third protrusion 53. The front end of the fourth protrusion 54 is, for example, arc-shaped along the outer periphery of the outer member 13. The fourth protrusions 54 provided on each third protrusion 53 are arranged in the longitudinal direction of the outer member 13. The fourth protrusions 54 are fitted into the recesses 13a of the outer member 13. Thus, the fourth protrusions 54 engage with the recesses 13a in the longitudinal direction of the outer member 13. Therefore, it is more difficult for the connecting member 41 and the outer member 13 to move relative to each other in the longitudinal direction of the outer member 13.

[0098] Each connecting member 41 has a fifth protrusion 55 protruding from the inner peripheral surface of the cover portion 43. The fifth protrusion 55 is provided in the portion of the connecting member 41 that surrounds the second path limiting member 31. The fifth protrusion 55 protrudes in a direction orthogonal to the length direction of the wire harness body 11. For example, multiple fifth protrusions 55 are provided. The multiple fifth protrusions 55 are arranged in the length direction of the outer component 13. The front end of each fifth protrusion 55 is, for example, arc-shaped along the outer periphery of the outer component 13. The front end of each fifth protrusion 55 is respectively fitted into the recess 13a of the outer component 13. Thus, each fifth protrusion 55 engages with the recess 13a in the length direction of the outer component 13. Therefore, it is more difficult for the connecting member 41 and the outer component 13 to move relative to each other in the length direction of the outer component 13.

[0099] The function of this embodiment will be explained.

[0100] In the path of the wire harness body 11, in the straight section 11s where the first path limiting member 21 is installed, the rigidity of the first path limiting member 21 suppresses the bending of the wire harness body 11 due to its own weight. Similarly, in the bent section 11c where the second path limiting member 31 is installed, the rigidity of the second path limiting member 31 suppresses the bending of the wire harness body 11 due to its own weight.

[0101] like Figure 6 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 to the assembly surface A by the fixing member is, for example, 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.

[0102] With the wiring harness 10 assembled on the assembly surface A, the cover 43 of the connecting member 41 is located closer to the assembly surface A than the main body 42. When the vehicle V is on the ground and the assembly surface A is under the floor of the vehicle V, the assembly surface A faces the ground. Therefore, the main body 42 of the connecting member 41 is located closer to the ground than the cover 43.

[0103] Here, in the first path limiting member 21, the circumferential position of the first insertion port 22 is positioned by the first protrusion 51 of the cover portion 43. Therefore, the first insertion port 22 is configured to face the cover portion 43 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. As a result, the outer component 13 can be appropriately protected from the impact of, for example, flying objects or water droplets by the first path limiting member 21. Furthermore, this can contribute to improving the durability of the wiring harness body 11.

[0104] In addition, such as Figure 7 As shown, the second path limiting member 31 is configured to overlap with the main body 42. That is, when the wire harness 10 is assembled on the assembly surface A, the second path limiting member 31 covers the ground side of the outer component 13. Therefore, the outer component 13 can be appropriately protected from, for example, flying objects or water droplets by the second path limiting member 31. Furthermore, this contributes to improving the durability of the wire harness body 11.

[0105] In this embodiment, the circumferential orientation of the connecting member 41 can be changed. Specifically, the circumferential orientation of the connecting member 41 is changed depending on which of the plurality of through holes 35 arranged circumferentially in the second path limiting member 31 the third protrusion 53 of the connecting member 41 engages with. Furthermore, if the circumferential orientation of the connecting member 41 changes, the circumferential orientation of the first path limiting member 21, which is positioned by the first protrusion 51 of the connecting member 41, also changes.

[0106] like Figure 7 As shown, the through hole in the middle of the three through holes 35 arranged in the circumferential direction is designated as through hole 35a, and the through holes on both sides of through hole 35a are designated as through holes 35b.

[0107] exist Figure 4 and Figure 7 In the shown state, the third protrusion 53 is fitted into the through hole 35a. In this state, the opening direction of the first insertion port 22 of the first path limiting member 21 is the same as the opening direction of the second insertion port 34 of the second path limiting member 31.

[0108] On the other hand, Figure 8 and Figure 9 In the shown state, the third protrusion 53 is fitted into the through hole 35b. In this state, the opening direction of the first insertion port 22 of the first path limiting member 21 is not the same as the opening direction of the second insertion port 34 of the second path limiting member 31.

[0109] Thus, in this embodiment, the first path limiting member 21 can be positioned circumferentially relative to the connecting member 41, and the circumferential orientations of the connecting member 41 and the first path limiting member 21 can be changed. Consequently, the circumferential orientation of the first path limiting member 21 can be changed according to the bending path of the wire harness body 11, such that the first insertion port 22 faces the assembly surface A. As a result, this helps to increase the degree of freedom in the layout of the wire harness 10.

[0110] The effects of this implementation method will be explained.

[0111] (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. Moreover, the first path limiting member 21 and the second path limiting member 31 are arranged together in the length direction of the wire harness body 11. Therefore, the position of the first path limiting member 21 relative to the second path limiting member 31 can be adjusted.

[0112] The second path limiting member 31 has a through hole 35 that is a recessed portion radially recessed along the outer component 13. On the other hand, the connecting member 41 has a third protrusion 53 that engages with the through hole 35. Moreover, by engaging the third protrusion 53 with the through hole 35, the connecting member 41 can be securely connected to the second path limiting member 31.

[0113] The first insertion port 22 of the first path limiting member 21 is an opening formed along the length direction of the first path limiting member 21 and extends throughout the entire length of the first path limiting member 21. Therefore, after termination processing such as mounting the connector to the end of the wire 12 along its length, the first path limiting member 21 can be mounted to the outer component 13 through the first insertion port 22. This allows for the subsequent mounting of the first path limiting member 21, thus improving the ease of assembly of the wire harness 10.

[0114] (2) The connecting member 41 is configured to span the first path limiting member 21 and the second path limiting member 31 along the length of the wire harness body 11. Moreover, the connecting member 41 surrounds a portion of the outer periphery of the first path limiting member 21 along its length. According to this structure, the gap between the first path limiting member 21 and the second path limiting member 31, which are mounted on the outer periphery of the outer component 13, can be covered by the connecting member 41.

[0115] (3) The connecting member 41 has a first protrusion 51 that protrudes toward and is located within the first insertion port 22. According to this structure, the first protrusion 51 of the connecting member 41 can be configured to contact the first insertion port 22 of the first path limiting member 21 in the circumferential direction. Therefore, the first protrusion 51 of the connecting member 41 restricts the circumferential rotation of the first path limiting member 21, thereby suppressing circumferential rotation of the first path limiting member 21.

[0116] (4) The connecting member 41 has a main body 42 and a cover 43 connected to the main body 42. Furthermore, when the main body 42 and the cover 43 are connected, the connecting member 41 is annular, surrounding the outer periphery of the outer component 13 and the second path limiting member 31. According to this structure, by making the connecting member 41 annular, surrounding the outer component 13 and the second path limiting member 31, and by dividing the connecting member 41 into a main body 42 and a cover 43, the connecting member 41 can be subsequently installed onto the outer component 13 and the second path limiting member 31. This further improves the assembly workability of the wire harness 10.

[0117] (5) A first protrusion 51 is provided on the cover portion 43. Furthermore, the cover portion 43 is configured to be closer to the assembly surface A than the main body portion 42. According to this structure, in the connecting member 41, the first protrusion 51 located within the first insertion port 22 of the first path limiting member 21 is provided on the cover portion 43, which is closer to the assembly surface A of the vehicle body. Additionally, the position of the first insertion port 22 in the circumferential direction of the first path limiting member 21 is positioned by the first protrusion 51 of the connecting member 41. 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 43 side of the connecting member 41, i.e., the assembly surface A side of the vehicle body. Therefore, the first protrusion 51 provided on the cover portion 43 can prevent the first insertion port 22 of the first path limiting member 21 from facing the side opposite to the assembly surface A of the vehicle body. As a result, the outer component 13 can be appropriately protected by the first path limiting member 21.

[0118] (6) The outer component 13 is a corrugated tube with alternating recesses 13a and protrusions 13b along its length. The connecting component 41 has a second protrusion 52 protruding from the first protrusion 51. Moreover, the second protrusion 52 engages with the recess 13a of the outer component 13. According to this structure, the second protrusion 52 of the connecting component 41 engages with the recess 13a of the outer component 13 along its length. Thus, relative movement of the outer component 13 with respect to the connecting component 41 in the length direction can be suppressed. In other words, the connecting component 41 is positioned relative to the outer component 13 in its length direction. Therefore, during the assembly of the wire harness 10, the position of the first path limiting member 21 relative to the second path limiting member 31 can be adjusted while the position of the connecting component 41 relative to the outer component 13 is fixed.

[0119] (7) The connecting member 41 has a fourth protrusion 54 protruding from the third protrusion 53. Furthermore, the fourth protrusion 54 engages with the recess 13a of the outer component 13. According to this structure, the fourth protrusion 54 of the connecting member 41 engages with the recess 13a of the outer component 13 in the longitudinal direction of the outer component 13. This suppresses relative movement of the outer component 13 relative to the connecting member 41 in the longitudinal direction. In other words, the connecting member 41 is positioned relative to the outer component 13 in its longitudinal direction. Therefore, during the assembly of the wire harness 10, the position of the first path limiting member 21 relative to the second path limiting member 31 can be adjusted while the position of the connecting member 41 relative to the outer component 13 is fixed.

[0120] (8) Multiple through holes 35 are provided in the circumferential direction of the second path limiting member 31. According to this structure, it is possible to select which of the multiple through holes 35 provided in the circumferential direction of the second path limiting member 31 the third protrusion 53 of the connecting member 41 is engaged with according to the path at the bend 11c of the wire harness body 11. Therefore, the degree of freedom in the layout of the wire harness 10 can be improved.

[0121] (9) The second path limiting member 31 has a second insertion port 34, which is an opening extending along the entire length of the second path limiting member 31. Therefore, after termination processing such as installing the 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 34. This allows for the subsequent installation of the second path limiting member 31, thus improving the ease of assembly of the wire harness 10.

[0122] Furthermore, the second path limiting member 31 in this embodiment does not have a cover that blocks the second insertion port 34. Therefore, after the second path limiting member 31 is installed on the outer component 13, there is no step of closing the cover, which helps to improve the assembly workability of the wire harness 10.

[0123] (10) The first path limiting member 21 is provided on both sides of the pair of straight portions 11s on the bend portion 11c in the path of the wire harness body 11. Furthermore, connecting members 41 are respectively provided at both ends of the second path limiting member 31 in the length direction of the wire harness body 11. According to this structure, each first path limiting member 21 arranged on both sides of the second path limiting member 31 in the length direction of the wire harness body 11 is arranged in relation to the second path limiting member 31 in the length direction of the wire harness body 11. Therefore, the position of each first path limiting member 21 relative to the second path limiting member 31 can be adjusted.

[0124] (11) The first path limiting member 21 has: a first end 23 and a second end 24 forming a first insertion port 22 at both circumferential ends of the first path limiting member 21; and a contact portion 26 protruding from the inner surface of each of the first end 23 and the second end 24 and contacting 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 contact portion 26, thereby improving the workability when inserting the first protrusion 51 of the connecting member 41 into 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.

[0125] (12) The contact portion 26 protrudes from the inner surfaces of the front end 23a of the first end 23 and the front end 24a of the second end 24. According to this structure, for example, compared to the case where the contact portion 26 protrudes from the inner surfaces of the front end 23a of the first end 23 and the front end 24a of the second end 24, the first path limiting member 21 can be more effectively prevented from disengaging from the outer component 13 through the first insertion port 22.

[0126] (13) When viewed from the length direction of the first path limiting member 21, the front end 23a of the first end 23 and the front end 24a of the second end 24 are bent. Therefore, the outer component 13 can be smoothly inserted into the interior of the first path limiting member 21 through the first insertion port 22 formed by the front ends 23a and 24a. In addition, the outer component 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.

[0127] (14) 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 along its length. In addition, a single extrusion molding machine can be used to manufacture a variety of first path limiting members 21 with different dimensions in the length direction.

[0128] (15) The contact portion 26 extends along the entire length of the first path limiting member 21. This structure improves the bending rigidity of the first path limiting member 21. Furthermore, the contact portion 26 contacts the outer surface of the outer component 13 along the entire length of the first path limiting member 21. Therefore, the first path limiting member 21 can be prevented from detaching from the outer component 13 through the first insertion port 22 throughout its entire length.

[0129] This embodiment can be implemented with the following modifications. This embodiment and the following variations can be combined with each other to implement them without creating technical inconsistencies.

[0130] In each through-hole group 35G, the arrangement and number of through holes 35 are not limited to the above-described embodiment and can be appropriately modified. For example, in each through-hole group 35G of the above-described embodiment, the number of rows of through holes 35 in the length direction of the second path limiting member 31 is set to two, but this number can also be changed to one or more rows. In addition, in each through-hole group 35G of the above-described embodiment, three through holes 35 are provided along the circumference of the second path limiting member 31, but in addition, for example, two or more through holes 35 can be provided along the circumference. Alternatively, the structure can be modified to provide one through hole 35 at each of the two ends of the second path limiting member 31.

[0131] In the above embodiment, the first engaging portion that engages with the third protrusion 53 is configured as a through hole 35 that radially penetrates the second path limiting member 31. However, in other cases, the first engaging portion may be configured as a recess that does not penetrate the second path limiting member 31.

[0132] In the above embodiment, the first engaging portion of the second path limiting member 31 is configured as a through hole 35, and the second engaging portion of the connecting member 41 is configured as a third protrusion 53. The first engaging portion and the second engaging portion are in a concave-convex fit, but their concave-convex relationship can also be reversed. In this case, the second path limiting member 31 has a protrusion that is a first engaging portion protruding from the outer peripheral surface of the second path limiting member 31. Moreover, the connecting member 41 has a recess that is a second engaging portion that engages with the protrusion. For example, multiple recesses that are the second engaging portions are provided circumferentially, similar to the through hole 35 in the above embodiment. In addition, the recesses that are the second engaging portions are provided only in the main body portion 42 of the connecting member 41, or in both the main body portion 42 and the cover portion 43. By providing the recesses that are the second engaging portions in both the main body portion 42 and the cover portion 43, the range of changeability of the connecting member 41 and the first path limiting member 21 in the circumferential direction can be expanded.

[0133] In the connecting member 41, the first protrusion 51 and the second protrusion 52 may also be omitted. That is, the connecting member 41 may be configured so that it does not engage with the first path limiting member 21 in the circumferential direction. In addition, in the connecting member 41, the fourth protrusion 54 and the fifth protrusion 55 may also be omitted.

[0134] Alternatively, a first circumferential engaging portion, consisting of a protrusion or a recess, can be provided on the outer peripheral surface of the middle portion 25 in the first path limiting member 21, and a second circumferential engaging portion, which engages with the first circumferential engaging portion, can be provided on the inner peripheral surface of the main body portion 42 in the connecting member 41. Furthermore, the first path limiting member 21 can be positioned circumferentially relative to the connecting member 41 by engaging the first circumferential engaging portion and the second circumferential engaging portion in the first path limiting member 21.

[0135] In the connecting member 41 of the above embodiment, the main body 42 and the cover 43 are integrally formed, but it is not particularly limited thereto, and the main body 42 and the cover 43 can also be separated.

[0136] In the above embodiment, the contact portion 26 protrudes from the front end 23a of the first end portion 23, but is not limited thereto. Alternatively, the contact portion 26 may be positioned further away from the first insertion port 22 than the front end 23a of the first end portion 23 in the circumferential direction of the first path limiting member 21. Similarly, in the above embodiment, the contact portion 26 protrudes from the front end 24a of the second end portion 24, but is not limited thereto. Alternatively, the contact portion 26 may be positioned further away from the first insertion port 22 than the front end 24a of the second end portion 24 in the circumferential direction of the first path limiting member 21.

[0137] In the first path limiting member 21, a contact portion 26 may also be provided locally along the length direction of the first path limiting member 21.

[0138] In the first path limiting component 21, at least one of the contact portion 26 of the first end 23 and the contact portion 26 of the second end 24 may be omitted.

[0139] In the first path limiting member 21, a second contact portion may also be provided, protruding from the inner surface of the middle portion 25 and contacting the outer surface of the outer component 13. According to this structure, both the contact portion 26 and the second contact portion can contact the outer surface of the outer component 13, thereby suppressing the shaking of the first path limiting member 21.

[0140] In the first path limiting member 21, a groove extending along the length direction may also 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 can contribute to improving the assemblability of the first path limiting member 21.

[0141] In the first path limiting member 21, the radial thickness of the intermediate portion 25 may also vary in the circumferential direction.

[0142] 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.

[0143] In the above embodiment, the first path limiting member 21 is arranged relative to the second path limiting member 31 via a small gap in the longitudinal direction of the wire harness body 11. However, it is not limited to this; the first path limiting member 21 may also contact the second path limiting member 31 in the longitudinal direction of the wire harness body 11.

[0144] In the above embodiments, the outer component 13 may also be configured such that a slit extending along the length of the outer component 13 is provided, which can fix the first path limiting component 21 to the slit.

[0145] The number of second path limiting components 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 components 31 is one or more.

[0146] In the above embodiment, the first path limiting component 21 is respectively disposed on both sides of the second path limiting component 31 in the length direction of the wire harness body 11, but the first path limiting component 21 may also be disposed on only one side of the second path limiting component 31 in the length direction.

[0147] 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.

[0148] The embodiments and variations disclosed herein should be considered illustrative rather than limiting in all respects. The scope of the invention is not as defined above, but as set forth in the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0149] It can also be like Figure 2 As shown, the connecting member 41 has a first recess on the outer surface of the cover 43 corresponding to the first protrusion 51, and a second recess on the outer surface of the cover 43 corresponding to the fifth protrusion 55. The width of the first recess along the length direction of the connecting member 41 and the width along the circumference direction of the connecting member 41 may be different from the width of the second recess along the length direction of the connecting member 41 and the width along the circumference direction of the connecting member 41.
