[0009] [Description of embodiments of this disclosure] First, embodiments of the present disclosure will be described and explained in parallel. The wire harness disclosed herein includes: [1] A wire harness body having a wire component and an outer component covering the outer periphery of the wire component; a first path limiting member fitted to the outer periphery of the outer component to limit the path of the wire harness body; and an assembly member fitted to a portion of the outer periphery of the first path limiting member in the length direction, the first path limiting member having an insertion port that opens in a direction orthogonal to the length direction of the first path limiting member and extends throughout the entire length direction of the first path limiting member, the assembly member having: a receiving portion covering a portion of the circumference of the first path limiting member; a cover that, together with the receiving portion, covers the entire circumference of the first path limiting member; and a restraining member that presses into the receiving portion from the outside of the cover to restrain the cover from separating from the receiving portion, the receiving portion and the cover clamping the first path limiting member.

[0010] According to this configuration, since it has a suppressing member that presses into the receiving portion from the outside of the cover to prevent the cover from separating from the receiving portion, separation of the cover from the receiving portion can be suppressed. Furthermore, the receiving portion and the cover clamp the first path limiting member. In this way, for example, compared to a configuration where the cover is simply integrated with the receiving portion via a thin-walled hinge portion, and the cover is locked to the receiving portion in the closed state by the engagement of the claw portion, wobbling between the receiving portion and the cover can be suppressed. That is, in a configuration with a thin-walled hinge portion and claw portion, wobbling between the receiving portion and the cover easily occurs at various points of the hinge portion and claw portion, but this wobbling can be avoided according to the above configuration. Therefore, the first path limiting member can be clamped between the receiving portion and the cover without wobbling, and wobbling between the first path limiting member and the assembly member can be suppressed.

[0011] [2] Preferably, the suppressing member is a C-ring that is flexible and covers the receiving portion and the cover from the outside. According to this configuration, the suppressing member is a C-ring that is flexible and covers the receiving part and the cover from the outside, so that the cover and the receiving part can be separated with a simple configuration.

[0012] [3] Preferably, one end of the receiving part in the circumferential direction is connected to the other end of the cover in the circumferential direction via a hinge, and the suppressing member is a spring member that springs in a direction that brings the other end of the receiving part in the circumferential direction closer to the one end of the cover in the circumferential direction.

[0013] According to this configuration, the suppressing member is a spring member that springs in the direction that brings the other end of the receiving part in the circumferential direction closer to the one end of the cover in the circumferential direction. Therefore, the spring force of the spring member can effectively suppress the separation of the cover from the receiving part.

[0014] [4] Preferably, the suppressing member is a strapping tape that covers the entire circumference of the receiving part and the cover and binds the receiving part to the cover. According to this configuration, since the restraining member is a strap that covers the entire circumference of the receiving part and the cover and binds the receiving part and the cover together, the separation of the cover and the receiving part can be restrained with a simple configuration.

[0015] [5] Preferably, at least one of the receiving portion and the cover is an engaging portion that can engage with the suppressing member in the length direction of the assembly member. According to this configuration, at least one of the receiving part and the cover has an engaging part that can engage with the suppressing member in the longitudinal direction of the assembly member. Therefore, the suppressing member can suppress the assembly member from shifting in the longitudinal direction.

[0016] [6] Preferably, the assembly component is a second path limiting component, which is assembled on the outer periphery of the outer component to limit the path of the wire harness body, and the receiving part is disposed at the end of the second path limiting component in the length direction to partially cover the circumferential part of the end of the first path limiting component in the length direction.

[0017] According to this configuration, the receiving portion is provided at the end of the second path limiting member in the longitudinal direction, partially covering the circumferential portion of the end of the first path limiting member in the longitudinal direction. Therefore, the first path limiting member and the second path limiting member are connected along the longitudinal direction. As a result, the wire harness body is continuously restricted in its path by the first path limiting member and the second path limiting member.

[0018] [7] Preferably, the first path limiting member limits the path of the straight portion, which is the straight part of the path of the wire harness body, and the second path limiting member limits the path of the curved portion, which is the bent part of the path of the wire harness body.

[0019] According to this configuration, the path of the straight portion is restricted by the first path restricting member, and the path of the curved portion is restricted by the second path restricting member. Thus, it is possible to continuously prevent the paths of both the straight and curved portions of the wire harness body from deviating from their desired paths.

[0020] [Detailed Description of Embodiments of this Disclosure] Specific examples of the wire harness disclosed herein will now be described with reference to the accompanying drawings. In the drawings, for ease of explanation, some components may be shown exaggeratedly or simplified. Furthermore, the dimensional ratios of the various parts may differ in different drawings. The terms "parallel" / "orthogonal" in this specification include not only strictly parallel / orthogonal cases, but also generally parallel / orthogonal cases within the scope of the effects of this embodiment. Moreover, the invention is not limited to these examples, but is defined by the scope of the claims, and is intended to include the meaning equivalent to the claims as well as all modifications within the scope of the claims.

[0021] (Overall structure of wire harness 10) Figure 1 The wiring harness 10 shown is, for example, mounted in a vehicle V such as a hybrid vehicle and / or an electric vehicle. The wiring harness 10 electrically connects two or more on-board devices to each other. On-board devices are electrical machines mounted in the vehicle V. For example, the wiring harness 10 electrically connects an inverter M1 located at the front of the vehicle V to a high-voltage battery M2 located further rearward than the inverter M1 in the vehicle V. The wiring harness 10 is, for example, formed as a long strip extending along the longitudinal direction of the vehicle V. For example, the wiring harness 10 is routed in the vehicle V such that its middle portion passes through the floor or other exterior parts of the vehicle V.

[0022] Inverter M1 is connected, for example, to a wheel drive motor (not shown) that serves as the power source for the vehicle. Inverter M1 generates alternating current from the direct current (DC) of high-voltage battery M2 and supplies this AC power to the motor. High-voltage battery M2 is, for example, a battery capable of supplying several hundred volts.

[0023] The wiring harness 10 has a wiring harness body 11. The wiring harness body 11 has a wire member 20 and a cylindrical outer casing 30 covering the outer periphery of the wire member 20. The wiring harness 10 has connectors C1 and C2 fitted to both ends of the wire member 20. One end of the wire member 20 in the longitudinal direction is connected to the inverter M1 via connector C1, and the other end of the wire member 20 in the longitudinal direction is connected to the high-voltage battery M2 via connector C2.

[0024] like Figure 2 as well as Figure 3 As shown, the wire harness 10 has a first path limiting member 40 mounted on the outer periphery of the outer component 30, and a second path limiting member 60 mounted on the outer periphery of the outer component 30 and serving as a mounting member. The first path limiting member 40 and the second path limiting member 60 limit the wiring path of the wire harness body 11. Furthermore, in Figure 1 The illustrations of the first path limiting member 40 and the second path limiting member 60 are omitted.

[0025] (Composition of electrical component 20) like Figure 4 as well as Figure 5 As shown, the wire component 20 may be one or more wires. In this embodiment, it has two wires 21 and a braided component 25 that surrounds the outer circumference of the multiple wires 21.

[0026] like Figure 5 As shown, each wire 21 is a covered wire having a core wire 22 and an insulating sheath 23. The core wire 22 is conductive, and the insulating sheath 23 surrounds the outer periphery of the core wire 22 and is insulating. Each wire 21 is, for example, a high-voltage wire capable of handling high voltage / high current. Each wire 21 can be, for example, an unshielded wire without its own electromagnetic shielding structure, or a shielded wire with its own electromagnetic shielding structure. In this embodiment, each wire 21 is an unshielded wire.

[0027] As the core wire 22, for example, a stranded wire formed by twisting together multiple metal wires and / or a single-core wire formed by a single conductor can be used. As a single-core wire, for example, a cylindrical conductor formed by a single metal rod with a solid internal structure and / or a cylindrical conductor with a hollow internal structure can be used. As the core wire 22, stranded wires, cylindrical conductors, and / or cylindrical conductors can be used in combination. As the material of the core wire 22, for example, copper-based and / or aluminum-based metal materials can be used.

[0028] The insulating sheath 23, for example, covers the entire circumference of the outer periphery of the core wire 22. The insulating sheath 23, for example, is made of an insulating resin material. The cross-sectional shape of each wire 21 obtained by cutting it with a plane orthogonal to its length direction can be any shape. For example, the cross-sectional shape of each wire 21 can be circular, semi-circular, polygonal, square, flat, etc. In this embodiment, the cross-sectional shape of each wire 21 is circular.

[0029] The braided member 25 is, for example, generally cylindrical, surrounding the outer circumference of the plurality of wires 21. As the braided member 25, for example, a braided wire made of multiple metal wires or a braided wire made by combining metal wires and resin wires can be used. As the material of the metal wires, for example, copper-based and / or aluminum-based metals can be used. Although not shown in the figure, connectors C1 and C2 (see [reference]) are used at both ends of the braided member 25 along its length. Figure 1 Grounding connection, etc.

[0030] (Composition of external component 30) like Figure 4 As shown, the outer casing 30 is cylindrical, surrounding the outer periphery of the wire component 20 throughout its entire circumference. In this embodiment, the outer casing 30 is formed in a cylindrical shape. For example, the outer casing 30 has a continuous circumferential wall formed throughout its entire circumference. For example, the outer casing 30 seals the interior of the outer casing 30 throughout its entire circumference. For example, the outer casing 30 has the function of protecting the wire component 20 from impacts from flying objects and / or water droplets from seeping in.

[0031] The outer component 30 is flexible, for example, and can be easily bent. Examples of flexible outer components 30 include, for example, a resin corrugated tube and / or a rubber waterproof cap. In this embodiment, the outer component 30 is a resin corrugated tube, which has a corrugated shape with large-diameter portions and small-diameter portions repeatedly arranged along the length of the outer component 30. That is, the outer component 30 of this embodiment has a corrugated structure in which large-diameter portions 31 and small-diameter portions 32 with diameters smaller than the large-diameter portions 31 are alternately and continuously provided along the length of the outer component 30. The large-diameter portions 31 and small-diameter portions 32 are each, for example, annular, encircling the circumference of the outer component 30. As the material for the outer component 30, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used, for example. Furthermore, in Figures 1-3 In order to simplify the accompanying drawings, the outer component 30 is shown in a simplified manner.

[0032] (The composition of the first path limiting member 40 and the second path limiting member 60) like Figure 2 as well as Figure 3As shown, the first path limiting member 40 and the second path limiting member 60 each hold the outer member 30. The first path limiting member 40 and the second path limiting member 60 are each, for example, more rigid than the outer member 30. The first path limiting member 40 and the second path limiting member 60 each have a stiffness that makes them less prone to bending in a direction orthogonal to the length direction of the wire harness body 11 than the outer member 30. Thus, the first path limiting member 40 and the second path limiting member 60 each restrict the path of the wire harness body 11. For example, the first path limiting member 40 and the second path limiting member 60 each assist the outer member 30 in a way that prevents the wire harness body 11 from bending due to its own weight and thus detaching from the desired path.

[0033] like Figure 2 As shown, a first path limiting member 40 is partially provided along the length of the wire harness body 11. The first path limiting member 40, for example, has a straight portion 11A, which is a straight section in the path of the wire harness body 11, fitted to the outer periphery of the outer component 30. The first path limiting member 40 restricts the path of the wire harness body 11 at the straight portion 11A. Here, the straight portion 11A is the portion of the wire harness body 11 that extends in a straight line in one direction. Furthermore, the first path limiting member 40 may be provided singly or in multiples depending on the path of the wire harness body 11.

[0034] The second path limiting member 60 is partially provided along the length direction of the wire harness body 11. The second path limiting member 60, for example, is fitted to the outer periphery of the outer component 30 as a bent portion 11B within the path of the wire harness body 11. The second path limiting member 60 restricts the path of the wire harness body 11 at the bent portion 11B. Here, the bent portion 11B is the portion of the wire harness body 11 whose path is bent away from a straight line. Furthermore, the second path limiting member 60 may be provided singly or in multiples depending on the path of the wire harness body 11.

[0035] (The structure of the first path limiting component 40) like Figure 5 As shown, the first path limiting member 40 covers a portion of the circumferential periphery of the outer component 30. The first path limiting member 40 is a shape that partially covers the circumferential periphery of the outer component 30. The cross-sectional shape of the first path limiting member 40 is generally C-shaped. For example, the first path limiting member 40 covers an area larger than half the circumference of the outer component 30. That is, the first path limiting member 40 covers an area larger than half the entire circumference of the outer component 30. Figure 2As shown, the first path limiting member 40 extends along the length direction of the outer member 30 in the straight portion 11A. The first path limiting member 40 is formed, for example, into a shape that extends in a straight line in one direction. The cross-sectional shape of the first path limiting member 40 is, for example, the same throughout the entire length direction of the first path limiting member 40.

[0036] The first path limiting member 40 is made of, for example, metal or resin. In this embodiment, the first path limiting member 40 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyoxymethylene can be used as the material for the first path limiting member 40. The first path limiting member 40 can be manufactured, for example, by known manufacturing methods such as extrusion molding / injection molding. In this embodiment, the first path limiting member 40 is an extruded article manufactured by extrusion molding. Therefore, by using an extrusion molding machine that extrudes the raw material of the first path limiting member 40 along its length direction, the first path limiting member 40 can be easily manufactured. Furthermore, multiple first path limiting members 40 with different dimensions in the length direction can be manufactured using a single extrusion molding machine. For example, by cutting the base material of the first path limiting member 40 formed by a single extrusion molding machine to any length using a cutting machine, multiple first path limiting members 40 with different dimensions in the length direction can be manufactured.

[0037] The first path limiting member 40 has an insertion port 40X that opens in a direction orthogonal to the length direction of the first path limiting member 40. The insertion port 40X extends throughout the entire length direction of the first path limiting member 40. The first path limiting member 40 has a first end 41 and a second end 42, which are the two circumferential ends of the first path limiting member 40 and form the insertion port 40X. The first path limiting member 40 has a connecting portion 43 that connects the first end 41 and the second end 42. In other words, the first path limiting member 40 has: a connecting portion 43 formed to partially cover the circumferential direction of the outer member 30; a first end 41 and a second end 42, which are provided at the two ends of the connecting portion 43; and an insertion port 40X formed by the first end 41 and the second end 42.

[0038] like Figure 5 As shown, the connecting portion 43 constitutes the main part of the first path limiting member 40. The radial thickness of the connecting portion 43 is the same in the circumferential direction of the first path limiting member 40, for example. The cross-sectional shape of the connecting portion 43 is formed, for example, along the outer surface of the outer member 30. The cross-sectional shapes of the first end 41, the second end 42, and the connecting portion 43 are formed, for example, in an arc shape.

[0039] The first end 41 and the second end 42 are disposed on opposite sides of the first path limiting member 40 in the circumferential direction. The first end 41 and the second end 42 are separated from each other in the circumferential direction of the first path limiting member 40 by an insertion opening 40X. In other words, in the circumferential direction of the first path limiting member 40, the gap between the first end 41 and the second end 42 constitutes the insertion opening 40X. Thus, the first path limiting member 40 is formed in a C-shape with the insertion opening 40X partially present in the circumferential direction of the first path limiting member 40.

[0040] The top ends of the first end 41 and the second end 42 are formed in a curved shape. In this embodiment, the top ends of the first end 41 and the second end 42 are formed in an arc shape.

[0041] The first path limiting member 40 has a protrusion 45 protruding from the inner surface of the first end 41 and a protrusion 46 protruding from the inner surface of the second end 42. Each protrusion 45, 46 protrudes toward the outer member 30 inserted into the first path limiting member 40 and contacts the outer surface of the outer member 30. Each protrusion 45, 46 contacts the outer surface of the large-diameter portion 31 of the outer member 30. For example, the protrusion 45 protrudes from the inner surface of the tip of the first end 41. For example, the protrusion 46 protrudes from the inner surface of the tip of the second end 42. The cross-sectional shape of each protrusion 45, 46 is, for example, formed as a curved shape. In this embodiment, the cross-sectional shape of each protrusion 45, 46 is formed as an arc shape.

[0042] like Figure 3 As shown, each protrusion 45, 46 extends along the length direction of the first path limiting member 40. Each protrusion 45, 46 extends, for example, along the entire length direction of the first path limiting member 40.

[0043] Each protrusion 45, 46 presses against the outer component 30 from the outside. The outer component 30 is elastically held by the protrusions 45, 46 and the connecting part 43. As a result, the connection between the first path limiting member 40 and the outer component 30 becomes secure.

[0044] like Figure 5 As shown, the opening width of the insertion port 40X, that is, the shortest distance between the first end 41 and the second end 42, is smaller than the outer diameter of the outer component 30. The opening width of the insertion port 40X increases due to the elastic deformation of the first path limiting member 40. For example, the opening width of the insertion port 40X increases because the outer member 30 is inserted into the insertion port 40X from a direction orthogonal to the length direction of the first path limiting member 40. If the outer member 30 is inserted inside the first path limiting member 40, the first path limiting member 40 elastically returns to its original shape. As a result, the opening width of the insertion port 40X is smaller than the outer diameter of the outer member 30, and therefore, the first path limiting member 40 is fitted to the outer periphery of the outer member 30.

[0045] (The structure of the second path limiting component 60) like Figure 2 As shown, the second path limiting member 60 is fitted to a portion of the outer periphery of the first path limiting member 40 along its length. The second path limiting member 60 is fitted to the outer periphery of the end portion of the first path limiting member 40 along its length. Additionally, the second path limiting member 60 is fitted to the outer periphery of the outer member 30 at the bend 11B. The second path limiting member 60 extends along the length of the outer member 30 at the bend 11B. The second path limiting member 60 is, for example, bent along the shape of the bend 11B.

[0046] The second path limiting member 60 has a second path limiting body 61, a cover 62, and a suppressing member 63. The second path limiting member 60 is made of, for example, metal or resin. In this embodiment, the second path limiting member 60 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyoxymethylene can be used as the material for the second path limiting member 60. The second path limiting member 60 can be manufactured, for example, by a known manufacturing method such as injection molding.

[0047] The second path limiting body 61 has a main body portion 64 and a receiving portion 65. In this embodiment, the receiving portion 65 and the cover 62 constitute a covering portion 66. The main body 64 partially covers the circumferential periphery of the outer component 30. The main body 64 is shaped to partially cover the circumferential periphery of the outer component 30. The cross-sectional shape of the main body 64 is generally semi-cylindrical. The main body 64 covers half of the outer periphery of the outer component 30. Figure 2 As shown, the main body 64 extends along the length direction of the outer component 30 at the bend 11B. The main body 64 is bent along the shape of the bend 11B.

[0048] The receiving portion 65 is provided at the end of the second path limiting member 60 in the longitudinal direction, that is, at the end of the main body portion 64 in the longitudinal direction. The receiving portion 65 partially covers the circumferential portion of the first path limiting member 40. The receiving portion 65 partially covers the circumferential portion at the end of the first path limiting member 40 in the longitudinal direction. The receiving portion 65 is shaped to partially cover the outer periphery of the first path limiting member 40 in the circumferential direction. The cross-sectional shape of the receiving portion 65 is generally semi-cylindrical. The receiving portion 65 is a semi-cylindrical shape with a diameter larger than that of the main body portion 64. The receiving portion 65 covers half of the outer periphery of the first path limiting member 40.

[0049] The receiving portion 65 and the cover 62 are integrally formed from the same material. That is, the second path limiting member 60 of this embodiment is an integrally formed member, including the second path limiting body 61 and the cover 62, which are entirely formed from the same material. The cover 62 is connected to the receiving portion 65 via a thin-walled hinge portion 67. Specifically, the other end of the cover 62 in the circumferential direction is connected to one end of the receiving portion 65 in the circumferential direction via the thin-walled hinge portion 67. The cover 62 is rotatable relative to the receiving portion 65 about the hinge portion 67. The covering portion 66 can be transformed into a closed state where the receiving portion 65 and the cover 62 are closed, and an open state where the receiving portion 65 and the cover 62 are open. The covering portion 66 covers the outer periphery of the first path limiting member 40 in the closed state.

[0050] The cover 62 has a claw portion 68. Additionally, the receiving portion 65 has a engaged portion 69 that the claw portion 68 can engage with. Specifically, the engaged portion 69 is located at the other end of the receiving portion 65 in the circumferential direction. The claw portion 68 is located at one end of the cover 62 in the circumferential direction. When the covering portion 66 is in the closed state, the claw portion 68 engages with the engaged portion 69. By engaging the claw portion 68 with the engaged portion 69, the cover 62 is fixed so that it cannot rotate relative to the receiving portion 65. Specifically, if the claw portion 68 engages with the engaged portion 69, the receiving portion 65 and the cover 62 are formed so that they cannot rotate relative to each other, and the covering portion 66 remains in the closed state.

[0051] The cover 62 and the receiving portion 65 together cover the entire circumference of the first path limiting member 40. Specifically, with the covering portion 66 in a closed state, the cover 62, together with the receiving portion 65, covers the entire circumference of the first path limiting member 40. In this embodiment, the cover 62 covers a portion of the outer circumference of the first path limiting member 40 and the portion exposed from the insertion opening 40X on the outer circumference of the outer member 30. The cross-sectional shape of the cover 62 is generally semi-cylindrical. The cover 62 has a semi-cylindrical shape with the same diameter as the receiving portion 65. The cover 62 covers the portion of the outer circumference of the first path limiting member 40 that is not covered by the receiving portion 65, that is, half of the circumference of the first path limiting member 40.

[0052] like Figure 4 As shown, the cover 62 has one or more protrusions 70 projecting from its inner surface; in this embodiment, it has five protrusions 70. The protrusions 70 are spaced apart along the length of the second path limiting member 60. Each protrusion 70 is, for example, located in the circumferential middle portion of the cover 62. Figure 5 As shown, for example, with the covering portion 66 in a closed state and the cover 62 in a closed position, each protrusion 70 protrudes toward the outer member 30 inserted inside the second path limiting member 60. Each protrusion 70 is, for example, formed such that it is embedded between the large-diameter portions 31 of the outer member 30 when the cover 62 is in the closed position. Each protrusion 70 is, for example, formed such that its tip contacts the outer peripheral surface of the small-diameter portion 32. The tip of each protrusion 70 is, for example, arc-shaped along the outer peripheral surface of the small-diameter portion 32. Therefore, movement of the outer member 30 relative to the second path limiting member 60 can be suppressed in the longitudinal direction of the outer member 30. Thus, the offset of the second path limiting member 60 relative to the outer member 30 in the longitudinal direction of the wire harness body 11 can be appropriately suppressed.

[0053] like Figure 2 as well as Figure 5 As shown, the receiving portion 65 and the cover 62 constituting the covering portion 66 have engaging recesses 71 as engaging portions. The engaging recesses 71 are provided at the middle portion in the length direction of the covering portion 66. The engaging recesses 71 are recessed from the outer peripheral surfaces of the receiving portion 65 and the cover 62. The engaging recesses 71 are provided on most of the outer periphery of the receiving portion 65 and the cover 62 where the hinge portion 67, the claw portion 68, and the engaging portion 69 are not provided.

[0054] The suppressing member 63 is pressed in from the outside of the cover 62 to prevent the cover 62 from separating from the receiving part 65. In detail, the suppression member 63 of this embodiment is a flexible C-ring that covers the receiving portion 65 and the cover 62 from the outside. The suppression member 63 is C-shaped. In other words, the suppression member 63 is a C-shaped member with a shape that is less than 180° removed from a circle. The suppression member 63 of this embodiment is a C-shaped member with a shape that is less than 90° removed from a circle.

[0055] The suppressing member 63 is made of, for example, metal or resin. In this embodiment, the suppressing member 63 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyoxymethylene can be used as the material for the suppressing member 63. The suppressing member 63 can be manufactured, for example, by known manufacturing methods such as extrusion molding and / or injection molding.

[0056] The suppressing member 63 is fitted into the receiving portion 65 and the cover 62 by means of engaging the engaging recess 71. The suppressing member 63 engages with the engaging recess 71 in the longitudinal direction of the second path limiting member 60, thereby suppressing the displacement of the second path limiting member 60 in the longitudinal direction. In addition, the suppressing member 63 has a recess 72 on its inner surface at the center of its circumference. The suppressing member 63 is fitted into the receiving portion 65 and the cover 62 by means of a hinge portion 67 engaging the recess 72. The suppressing member 63 presses the receiving portion 65 and the cover 62 together. Even if the receiving portion 65 and the cover 62 slightly separate due to the engagement state of the claw portion 68 and the engaged portion 69 and / or the deformation of the hinge portion 67, the suppressed member 63 is pressed in from the outside of the cover 62 to suppress the separation of the cover 62 from the receiving portion 65. Thus, the receiving portion 65 and the cover 62 clamp the first path limiting member 40. In other words, the receiving part 65 and the cover 62 maintain the state of clamping the first path limiting member 40 by the inhibiting member 63.

[0057] In addition, such as Figure 2 As shown, the wire harness 10, for example, has a sliding limiting member 73 that restricts the sliding movement of the first path limiting member 40 relative to the outer member 30 in the longitudinal direction. The wire harness 10, for example, has a sliding limiting member 74 that restricts the sliding movement of the second path limiting member 60 relative to the outer member 30 in the longitudinal direction. As sliding limiting members 73 and 74, resin or metal strapping, rivet rings, and / or tape can be used, for example. In this embodiment, the sliding limiting members 73 and 74 are tape. The sliding limiting member 73 is wound across the end of the first path limiting member 40 that is not connected to the second path limiting member 60 and over the outer member 30. The sliding limiting member 74 is wound across the end of the second path limiting member 60 that is not connected to the first path limiting member 40 and over the outer member 30.

[0058] Next, the function of this embodiment will be explained. The retaining member 63 prevents the receiving portion 65 from separating from the cover 62. Thus, the receiving portion 65 and the cover 62, constituting the covering portion 66, maintain a state where they clamp the first path limiting member 40. This maintains the connection between the first path limiting member 40 and the second path limiting member 60. Consequently, the path of the wire harness body 11 is continuously limited.

[0059] The effects of the above implementation methods will be described below. (1) The cover 62 is pressed in from the outside to prevent separation between the cover 62 and the receiving portion 65, thus preventing separation between the cover 62 and the receiving portion 65. Furthermore, the receiving portion 65 and the cover 62 clamp the first path limiting member 40. In this way, for example, compared to a configuration where the cover 62 is integrally formed with the receiving portion 65 via a thin-walled hinge portion 67, and the cover 62 is locked to the receiving portion 65 by the engagement of the claw portion 68 in the closed state, the shaking of the receiving portion 65 and the cover 62 can be suppressed. That is, in a configuration with a thin-walled hinge portion 67 and claw portion 68, shaking of the receiving portion 65 and the cover 62 is less likely to occur at various points of the hinge portion 67 and the claw portion 68, thus preventing such shaking. Therefore, the first path limiting member 40 can clamp the receiving portion 65 and the cover 62 without shaking, and the shaking of the first path limiting member 40 and the second path limiting member 60 can be suppressed. As a result, for example, damage to the assembly parts of the first path limiting member 40 and the second path limiting member 60 can be suppressed, thereby stably limiting the path of the wire harness body 11.

[0060] (2) The suppressing member 63 is a C-ring that is flexible and covers the receiving part 65 and the cover 62 from the outside. Therefore, the suppressing cover 62 can be separated from the receiving part 65 with a simple configuration. (3) The receiving part 65 and the cover 62 have a engaging recess 71 that can engage with the suppressing member 63 in the length direction of the second path limiting member 60, so that the suppressing member 63 can be suppressed from shifting in the length direction of the second path limiting member 60.

[0061] (4) The assembly member fitted to the first path limiting member 40 is the second path limiting member 60, which is fitted to the outer periphery of the outer component 30 and limits the path of the wire harness body 11. Furthermore, the receiving portion 65 is provided at the end of the second path limiting member 60 in the longitudinal direction, partially covering the circumferential portion of the end of the first path limiting member 40 in the longitudinal direction, thus connecting the first path limiting member 40 and the second path limiting member 60 along the longitudinal direction. Therefore, the wire harness body 11 is continuously limited in its path by the first path limiting member 40 and the second path limiting member 60.

[0062] (5) The path of the straight portion 11A of the wire harness body 11 is restricted by the first path restricting member 40, and the path of the curved portion 11B of the wire harness body 11 is restricted by the second path restricting member 60. As a result, the paths of the straight portion 11A and the curved portion 11B of the wire harness body 11 are continuously suppressed from deviating from the desired paths.

[0063] (Other implementation methods) The above-described embodiments can be modified as follows. The above-described embodiments and the following variations can be combined with each other within the scope of technical inconsistency.

[0064] In the above embodiment, the suppressing member 63 is a flexible C-ring that covers the receiving portion 65 and the cover 62 from the outside. However, as long as it can be pressed in from the outside of the cover 62 to suppress the separation of the cover 62 from the receiving portion 65, it can be changed to a suppressing member with other configurations.

[0065] For example, it can be like Figure 6 The modification is as shown. In this example, the receiving portion 65 and the cover 62 are the same as in the above embodiment, with one circumferential end of the receiving portion 65 connected to the other circumferential end of the cover 62 via a thin-walled hinge portion 67. Furthermore, the receiving portion 65 and the cover 62 in this example do not have the engaging recess 71 of the above embodiment. Moreover, the restraining member 81 in this example is a spring member that springs in a direction that brings the other circumferential end of the receiving portion 65 closer to one circumferential end of the cover 62. The restraining member 81 is made of metal. Specifically, it is a torsion coil spring. The restraining member 81 has a coil portion 82 and arm portions 83 extending from both ends of the coil portion 82. The coil portion 82 is positioned corresponding to the hinge portion 67, and the arm portions 83 are positioned along the outer peripheral surfaces of the receiving portion 65 and the cover 62, respectively. The top end of the arm 83 engages with the other end of the receiving part 65 in the circumferential direction and the one end of the cover 62 in the circumferential direction, respectively. The restraining member 81 presses against the top end of the arm 83 in a direction that brings the other end of the receiving part 65 in the circumferential direction closer to the one end of the cover 62 in the circumferential direction.

[0066] In this way, the first path limiting member 40 can be clamped securely by the receiving part 65 and the cover 62 without wobbling, and the wobbling of the first path limiting member 40 and the second path limiting member 60 can be suppressed. In addition, the suppressing member 81 is a spring member that springs in a direction that brings the other end of the receiving part 65 in the circumferential direction close to one end of the cover 62 in the circumferential direction, and the spring force of the spring member can effectively suppress the separation of the cover 62 from the receiving part 65.

[0067] Additionally, for example, it can be like Figure 7The change is as shown. In this example, the receiving portion 65 and the cover 62 are configured such that one circumferential end of the receiving portion 65 and the other circumferential end of the cover 62 are connected via a hinge portion 85. In this example, the receiving portion 65 and the cover 62 are separate. Moreover, the hinge portion 85 is configured by combining a hinge component 86 provided on the receiving portion 65 and a hinge component 87 provided on the cover 62. The cover 62 can rotate relative to the receiving portion 65 about the hinge portion 85. In addition, the receiving portion 65 and the cover 62 in this example do not have the engaging recess 71 of the above embodiment. Moreover, the suppressing member 88 in this example is a spring member that springs in a direction that brings the other circumferential end of the receiving portion 65 closer to the circumferential end of the cover 62. The suppressing member 88 is made of metal. The suppressing member 88 is a spring member, specifically a C-shaped spring. The suppressing member 88 is arranged along the outer peripheral surface of the receiving portion 65 and the cover 62. Both ends of the restraining member 88 engage with the other end of the receiving portion 65 in the circumferential direction and the other end of the cover 62 in the circumferential direction, respectively. The restraining member 88 is spring-loaded in a direction that brings the other end of the receiving portion 65 in the circumferential direction closer to the other end of the cover 62 in the circumferential direction. In addition, the receiving portion 65 and the cover 62 each have a holding piece 89 and 90 protruding from near the hinge components 86 and 87. The holding pieces 89 and 90 intersect. The receiving portion 65 and the cover 62 are opened, for example, by being held by an installer and rotated relative to each other by the holding pieces 89 and 90.

[0068] In this way, the first path limiting member 40 can be clamped securely without wobbling by the receiving part 65 and the cover 62, suppressing the wobbling of the first path limiting member 40 and the second path limiting member 60. Furthermore, the suppressing member 88 is a spring member that springs in a direction that brings the other end of the receiving part 65 in the circumferential direction closer to one end of the cover 62 in the circumferential direction; therefore, the spring force of the spring member effectively suppresses the separation of the cover 62 from the receiving part 65. Additionally, due to the presence of the holding pieces 89 and 90, the receiving part 65 and the cover 62 can be easily opened.

[0069] Additionally, for example, it can be like Figure 8The modification is as shown. In this example, the receiving portion 65 and the cover 62 are similar to those in the above embodiment, with one circumferential end of the receiving portion 65 and the other circumferential end of the cover 62 connected via a thin-walled hinge portion 67. Furthermore, the receiving portion 65 and the cover 62 in this example do not have the engaging recess 71 of the above embodiment. Moreover, the restraining member 91 in this example is a strapping band that completely covers the circumferential area of ​​the receiving portion 65 and the cover 62 and binds them together. The restraining member 91 is made of metal or resin. In this example, the restraining member 91 is made of resin. The restraining member 91 has: a flexible, soft strip 92, and a locking portion 93 provided at the end of the strip 92 in the longitudinal direction. The locking portion 93 restricts the movement of the strip 92 in the opposite direction of its passage, i.e., the disengagement direction, while the strip 92 is being passed through, thus locking the strip 92. The restraining member 91 passes through the locking part 93 while the strip 92 is circumferentially covering the receiving part 65 and the cover 62, thereby binding the receiving part 65 and the cover 62 together.

[0070] In this way, the first path limiting member 40 can be clamped without wobbling by the receiving part 65 and the cover 62, and the wobbling of the first path limiting member 40 and the second path limiting member 60 can be suppressed. In addition, the suppressing member 91 is a strap that covers the entire circumference of the receiving part 65 and the cover 62 and binds the receiving part 65 and the cover 62, so the suppressing cover 62 can be separated from the receiving part 65 with a simple configuration.

[0071] In the above embodiment, the receiving portion 65 and the cover 62 have a locking recess 71 that serves as a locking portion capable of engaging with the suppressing member 63 in the longitudinal direction of the second path limiting member 60. However, this is not a limitation; for example, it may be configured without a locking portion. Alternatively, for example, the locking recess 71 may be modified into a locking rib that protrudes from the outer peripheral surface of the receiving portion 65 and the cover 62 as a locking portion.

[0072] • In the above embodiment, the suppressing member 63 is configured to have only one, but it is not limited to this. For example, it can be configured to have two or more in the length direction of the covering portion 66.

[0073] • In the above embodiment, the cover 62 has 5 protrusions 70, but it is not limited to this. For example, the number of protrusions 70 can be changed, or it can be configured to not have protrusions 70.

[0074] The second path limiting member 60 in the above embodiment is formed to limit the path of the curved portion 11B of the wire harness body 11, but it is not limited thereto. For example, the second path limiting member 60 can be changed to a shape that limits the path of the straight portion 11A of the wire harness body 11. As the second path limiting member 60 in this case, for example, the bending shape at the main body portion 64 is changed to a shape that extends along a straight line.

[0075] In the above embodiment, the assembly member assembled to the first path limiting member 40 is specifically embodied as the second path limiting member 60, but is not limited thereto. For example, the assembly member may be embodied as a vehicle assembly member for assembling the first path limiting member 40 to the vehicle V.

[0076] • The structure of the first path limiting member 40 in the above embodiment can be appropriately modified. For example, as long as the first path limiting member 40 has an insertion port 40X and a structure that can be assembled to the outer periphery of the outer member 30, other structures are not particularly limited.

[0077] • The protrusion 45 of the above embodiment can be provided at a position in the circumferential direction of the first path limiting member 40 that is farther away from the insertion port 40X than the top end of the first end 41. • The protrusion 46 of the above embodiment can be provided at a position in the circumferential direction of the first path limiting member 40 that is further away from the insertion port 40X than the top end of the second end 42.

[0078] • The protrusions 45 and 46 of the above embodiment can be provided locally along the length direction of the first path limiting member 40. • At least one of the protrusions 45 and 46 in the above embodiments may be omitted.

[0079] • In the first path limiting member 40 of the above embodiment, the radial thickness of the connecting portion 43 may be configured to vary in the circumferential direction. • The shape of the connecting portion 43 in the first path limiting member 40 of the above embodiment is not limited to an arc shape, and can be changed to, for example, an elliptical arc shape or a U-shaped shape.

[0080] In the above embodiment, the first path limiting member 40 and the second path limiting member 60 are harder than the outer member 30, but this is not a limitation. The hardness of the first path limiting member 40 and the second path limiting member 60 may be the same as or lower than that of the outer member 30. That is, the first path limiting member 40 and the second path limiting member 60 only need to function to make the wire harness body 11 less prone to bending compared to the state in which the first path limiting member 40 and the second path limiting member 60 are not installed.

[0081] • The external component 30 in the above embodiment may, for example, have a metal layer containing a metallic material provided on the outer surface of a resin-made corrugated pipe. • The external component 30 in the above embodiments is not limited to a bellows, and may be an external component without a large diameter portion 31 and a small diameter portion 32.

[0082] • The outer component 30 of the above embodiment may have a slit extending along the length direction of the outer component 30. • In the above embodiment, the wire 21 is a high-voltage wire, but it is not limited to this. For example, the wire 21 can be a low-voltage wire.

[0083] In the wire component 20 of the above embodiment, the electromagnetic shielding component is specifically embodied as a braided component 25, but it is not limited thereto. For example, the electromagnetic shielding component in the wire component 20 may be specifically embodied as a metal sheet.

[0084] • The braided component 25 in the wire component 20 of the above embodiment can be omitted. In the above embodiment, two wires 21 constituting the wire member 20 are used, but this is not a limitation. The number of wires 21 can be one or more.

[0085] • The configuration relationship between the inverter M1 and the high-voltage battery M2 in vehicle V is not limited to the above implementation method and can be appropriately changed according to the vehicle configuration. In the above embodiment, the multiple vehicle-mounted devices electrically connected to the wiring harness 10 are specifically embodied as an inverter M1 and a high-voltage battery M2, but are not limited thereto. The multiple vehicle-mounted devices electrically connected to the wiring harness 10 can be any electrical machinery mounted on the vehicle V, and are not particularly limited thereto.
