[0009] [Description of embodiments of this disclosure] First, embodiments of the present disclosure will be described and explained in parallel. [1] The wire harness of this disclosure has: a wire harness body having a wire member and an outer member covering the outer periphery of the wire member; a path limiting member fitted to the outer periphery of the outer member to limit the path of the wire harness body; and an assembly member fitted to a portion of the outer periphery of the path limiting member in the length direction, the path limiting member having: a main body portion that partially covers the outer periphery of the outer member; and an insertion port that opens in a direction orthogonal to the length direction of the main body portion and extends throughout the entire length direction of the main body portion, the path limiting member having a connecting portion connected to the assembly member, the assembly member having a covering portion covering the outer periphery of the connecting portion, the covering portion having: a receiving portion that partially covers the circumferential direction of the path limiting member; a cover portion that, together with the receiving portion, covers the outer periphery of the path limiting member throughout the entire circumferential direction; and a joining portion that is formed by joining the receiving portion and the cover portion, the receiving portion and the cover portion clamping the path limiting member.

[0010] According to this structure, in the length direction of the wire harness body, the connecting portion of the path limiting member overlaps with the covering portion of the assembly member. In this case, the outer periphery of the path limiting member is covered by a receiving portion and a cover portion in the covering portion, and the receiving portion engages with the cover portion. In this way, for example, compared to a configuration where the cover portion is integrally formed with the receiving portion via a thin-walled hinge portion, and the cover portion is locked to the receiving portion in the closed state by the engagement of the claw portion, the wobbling between the receiving portion and the cover portion can be suppressed. That is, in a configuration with a thin-walled hinge portion and a claw portion, wobbling between the receiving portion and the cover portion easily occurs at various points of the hinge portion and the claw portion, but in a configuration where the receiving portion and the cover portion are engaged, such wobbling can be suppressed. Therefore, the path limiting member can be clamped without wobbling by the receiving portion and the cover portion, and the wobbling between the path limiting member and the assembly member can be suppressed.

[0011] [2] Preferably, the joining portion is formed by welding the receiving portion and the cover portion together. According to this structure, the receiving part and the cover part are joined by welding. Therefore, it is possible to join the receiving part and the cover part without introducing other components such as adhesives between them. Therefore, it is possible to suppress the increase in the number of parts at the covering part.

[0012] [3] Preferably, the receiving portion has a first fixing portion that protrudes radially outward from the circumferential end of the receiving portion toward the outer side of the covering portion, and the cover portion has a second fixing portion that protrudes radially outward from the circumferential end of the cover portion toward the outer side of the covering portion and overlaps with the first fixing portion, and the joining portion is a portion formed by welding the first fixing portion and the second fixing portion.

[0013] According to this structure, a first fixing part protruding radially outward from the circumferential end of the receiving part and a second fixing part protruding radially outward from the circumferential end of the cover part are welded together. This allows the welded portion to be positioned away from the internal space of the covering part. Therefore, the welded portion can be positioned away from the wire component housed within the internal space of the covering part. Consequently, it is possible to appropriately suppress the application of energy (heat, etc.) from an energy source (heat source, etc.) to the welded portion to the wire component during welding of the first and second fixing parts. As a result, damage to the wire component can be appropriately suppressed.

[0014] [4] Preferably, the first fixing part overlaps with the second fixing part in a direction orthogonal to the protrusion direction of the first fixing part. According to this structure, the first fixing part and the second fixing part overlap along a direction not facing the interior space of the covering part, and the overlapping first fixing part and the second fixing part are welded together. Therefore, it is possible to appropriately suppress the energy applied to the welding part from the energy source during welding of the first fixing part and the second fixing part from being applied to the wire component. As a result, damage to the wire component can be more appropriately suppressed.

[0015] [5] Preferably, the joining portion is formed by welding the end faces of the two circumferential sides of the receiving portion to the end faces of the two circumferential sides of the cover portion. According to this structure, the end faces on both circumferential sides of the receiving part and the end faces on both circumferential sides of the cover part are welded together. Therefore, without providing the receiving part and the cover part with portions protruding radially outward toward the covering part, the receiving part and the cover part can be joined together by welding. As a result, the radial enlargement of the covering part can be appropriately suppressed.

[0016] [6] Preferably, the joining portion is configured to not overlap with the insertion port in the radial direction of the covering portion, but to overlap with the main body portion. According to this structure, the main body of the path limiting member can be inserted between the wire harness body and the joint portion in the radial direction of the covering portion. Therefore, the main body of the path limiting member can absorb, for example, sputtering that may occur during welding, and can appropriately suppress damage to the wire harness body caused by sputtering.

[0017] [7] Preferably, an interference fit is provided between the outer periphery of the path limiting member and the inner periphery of the covering portion. According to this structure, the path limiting member is interference-fitted with the inner circumference of the covering portion. That is, when the path limiting member is fitted into the interior of the covering portion, the outer circumferential surface of the path limiting member contacts the inner circumferential surface of the covering portion with an interference fit. Thus, the path limiting member fitted into the interior of the covering portion is held by the inner surface of the covering portion in a state where it is always pressed radially inward toward the covering portion. Therefore, it is possible to suppress the wobbling of the path limiting member inside the covering portion. Furthermore, it is possible to appropriately suppress relative movement of the path limiting member relative to the covering portion in the longitudinal direction of the wire harness body. As a result, it is possible to appropriately suppress positional displacement of the path limiting member relative to the covering portion in the longitudinal direction of the wire harness body, and it is possible to appropriately suppress the path limiting member from detaching from the covering portion.

[0018] [8] Preferably, when the path limiting member is set as the first path limiting member, the assembly member is a second path limiting member assembled on the outer periphery of the outer assembly member and limiting the path of the wire harness body, the connecting part is disposed at the end of the first path limiting member in the length direction, and the covering part is disposed at the end of the second path limiting member in the length direction.

[0019] According to this structure, the first path limiting member and the second path limiting member are partially overlapped along the length of the wire harness body. Specifically, the connecting portion at the end of the first path limiting member along the length of the wire harness body and the covering portion at the end of the second path limiting member along the length of the wire harness body are overlapped along the length of the wire harness body. Therefore, the first path limiting member and the second path limiting member are connected along the length of the wire harness body. Thus, the path of the wire harness body can be continuously limited by the first path limiting member and the second path limiting member.

[0020] [9] Preferably, the first path limiting member restricts 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 restricts the path of the curved portion, which is the bent part of the path of the wire harness body.

[0021] According to this structure, 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 prevent the paths of the straight portion and the curved portion from deviating from their respective desired paths.

[0023] (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.

[0024] 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.

[0025] 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 that surrounds 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.

[0026] 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 50 mounted on the outer periphery of the outer component 30. The first path limiting member 40 and the second path limiting member 50 limit the wiring path of the wire harness body 11. Additionally, in Figure 1 The illustrations of the first path limiting member 40 and the second path limiting member 50 are omitted.

[0027] (Composition of wire component 20) like Figure 4 as well as Figure 5 As shown, the wire component 20 is, for example, one or more wires 21 (two in this embodiment) and a braided component 25 that surrounds the outer circumference of the multiple wires 21.

[0028] 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.

[0029] 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.

[0030] 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, or flat. In this embodiment, the cross-sectional shape of each wire 21 is circular.

[0031] 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.

[0032] (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, a circumferential wall is continuously formed throughout the entire circumference of the outer casing 30. For example, the outer casing 30 is sealed throughout its entire circumference. For example, the outer casing 30 has the function of protecting the wire component 20 from impacts by flying objects and / or water droplets.

[0033] The outer component 30 is flexible, for example, and can be easily bent. Examples of flexible outer components 30 include, for example, a resin-made corrugated tube and / or a rubber waterproof cap. In this embodiment, the outer component 30 is a resin-made corrugated tube with a corrugated structure in which annular protrusions 31 and annular recesses 32 are alternately and continuously provided along the length of the outer component 30. Each of the annular protrusions 31 and annular recesses 32 is, for example, annular in shape, surrounding the circumference of the outer component 30. As a material for the outer component 30, synthetic resins such as polyolefins, polyamides, polyesters, and ABS resins can be used. Furthermore, in Figures 1-3 In the diagram, the external component 30 is shown in a simplified form.

[0034] (The composition of the first path limiting member 40 and the second path limiting member 50) like Figure 2As shown, the first path limiting member 40 and the second path limiting member 50 each hold the outer member 30. The first path limiting member 40 and the second path limiting member 50 are each, for example, more rigid than the outer member 30. The first path limiting member 40 and the second path limiting member 50 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. Therefore, the first path limiting member 40 and the second path limiting member 50 each restrict the path of the wire harness body 11. For example, the first path limiting member 40 and the second path limiting member 50 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. The outer member 30 is, for example, less prone to bending than when the first path limiting member 40 and the second path limiting member 50 are not attached.

[0035] A first path limiting member 40 is provided locally along the length of the wire harness body 11. The first path limiting member 40, for example, is a straight portion 11A that forms a straight line along the path of the wire harness body 11, and is 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.

[0036] The second path limiting member 50 is partially provided along the length direction of the wire harness body 11. The second path limiting member 50, for example, is fitted to the outer periphery of the outer component 30 as a bent portion 11B in the path of the wire harness body 11. The second path limiting member 50 restricts the path of the wire harness body 11 at the bent portion 11B. Here, the bent portion 11B is a portion of the wire harness body 11 whose path is bent in a two-dimensional or three-dimensional shape. Furthermore, the second path limiting member 50 may be provided singly or in multiples depending on the path of the wire harness body 11.

[0037] (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 member 30. The first path limiting member 40 is cylindrical, partially covering the circumferential periphery of the outer member 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 more than half the circumference of the outer member 30. That is, the first path limiting member 40 covers half the entire circumference of the outer member 30. The cross-sectional shape of the first path limiting member 40 is, for example, the same along its entire length. Figure 2As shown, the first path limiting member 40 extends, for example, along the path of the straight section 11A, and is formed into a shape that extends in a straight line in one direction.

[0038] 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, a single extrusion molding machine can be used to manufacture various first path limiting members 40 with different dimensions in the length direction. For example, by using a cutting machine to cut the base material of the first path limiting member 40 formed by a single extrusion molding machine to an arbitrary length, various first path limiting members 40 with different dimensions in the length direction can be manufactured.

[0039] like Figure 5 As shown, the first path limiting member 40 has: a main body portion 41 that covers a portion of the outer periphery of the outer member 30; and an insertion port 42 that opens in a direction orthogonal to the length direction of the main body portion 41. The first path limiting member 40 has two circumferential ends that are the main body portion 41, and forms a first end portion 43 and a second end portion 44 of the insertion port 42.

[0040] The main body 41 constitutes the main part of the first path limiting member 40. The radial thickness of the main body 41 is the same in the circumferential direction of the first path limiting member 40, for example. The cross-sectional shape of the main body 41 is formed, for example, along the outer surface of the outer member 30. The cross-sectional shape of the main body 41 is formed, for example, an arc shape.

[0041] The first end 43 and the second end 44 are disposed on opposite sides of each other in the circumferential direction of the main body 41. The first end 43 and the second end 44 are disposed separately from each other in the circumferential direction of the main body 41 through the insertion opening 42. In other words, in the circumferential direction of the first path limiting member 40, the gap between the first end 43 and the second end 44 constitutes the insertion opening 42. Thus, the first path limiting member 40 is formed in a C-shape with the insertion opening 42 partially present in the circumferential direction of the main body 41.

[0042] The opening width of the insertion port 42, that is, the shortest distance between the first end 43 and the second end 44, is, for example, smaller than the outer diameter of the outer component 30. Figure 4As shown, the insertion port 42 extends along the entire length of the main body 41 in the length direction. That is, the insertion port 42 opens in a direction orthogonal to the length direction of the main body 41, and is formed to open at both ends in the length direction of the main body 41.

[0043] By inserting the outer component 30 into the insertion port 42 in a direction orthogonal to the length direction of the first path limiting member 40, the first path limiting member 40 elastically deforms, increasing the opening width of the insertion port 42. If the outer component 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 42 becomes smaller than the outer diameter of the outer component 30, thus the first path limiting member 40 is fitted onto the outer periphery of the outer component 30.

[0044] Furthermore, when the outer component 30 is inserted into the first path limiting member 40, the opening width of the insertion port 42 is not limited to returning to its original width, i.e., the width when the outer component 30 is not inserted. Specifically, because the elastic deformation of the main body 41 to return to its original shape is hindered by the outer component 30, the opening width of the insertion port 42 sometimes becomes slightly larger than its original width. Additionally, when the outer component 30 is inserted into the first path limiting member 40, the outer component 30 becomes flexed due to the pressure of the first path limiting member 40, thereby causing the opening width of the insertion port 42 to return to its original width. That is, the opening width of the insertion port 42 when the outer component 30 is inserted into the first path limiting member 40 is based on the rigidity and flexibility of the outer component 30 and the first path limiting member 40. In this embodiment, when the outer component 30 is inserted into the first path limiting member 40, the opening width of the insertion port 42 becomes slightly larger than its original width. The outer diameter of the first path limiting member 40 in this embodiment is configured such that, when the outer member 30 is inserted inside the first path limiting member 40, the outer diameter is larger than the outer diameter when the outer member 30 is not inserted by an amount corresponding to the protrusion amount of the protrusion 45.

[0045] like Figure 5 As shown, the first path limiting member 40 has, for example, protrusions 45 extending from the inner surfaces of the first end 43 and the second end 44 respectively. Each protrusion 45 protrudes toward the outer member 30 inserted into the first path limiting member 40 and is capable of contacting the outer surface of the outer member 30. Each protrusion 45, for example, contacts the outer surface of the annular protrusion 31 of the outer member 30. The cross-sectional shape of each protrusion 45 is formed, for example, a curved shape. In this embodiment, the cross-sectional shape of each protrusion 45 is formed as a semi-circular shape. Each protrusion 45 extends, for example, along the entire length of the first path limiting member 40 in the longitudinal direction.

[0046] Each protrusion 45 presses against the outer component 30 from the outside of the outer component 30, for example. The outer component 30 is elastically held by the two protrusions 45 and the main body 41. As a result, the connection between the first path limiting member 40 and the outer component 30 becomes secure. As a result, movement of the first path limiting member 40, which is fitted to the outer periphery of the outer component 30, in the longitudinal direction of the outer component 30 can be suppressed.

[0047] like Figure 2 as well as Figure 3 As shown, the first path limiting member 40 has a connecting portion 47 that connects to the second path limiting member 50. The connecting portion 47 is provided, for example, at one end of the first path limiting member 40 in the longitudinal direction.

[0048] (The composition of the second path restriction component 50) like Figure 2 As shown, the second path limiting member 50 is fitted to the outer periphery of the outer member 30 at the bend 11B. The second path limiting member 50 is bent, for example, along the shape of the bend 11B.

[0049] The second path limiting member 50 has: a covering portion 51 that partially covers the length of the first path limiting member 40; and a path limiting portion 52 that is fitted to the outer periphery of the outer member 30. The second path limiting member 50 is, for example, formed continuously in the length direction of the harness body 11 by the covering portion 51 and the path limiting portion 52. The covering portion 51 is, for example, provided at one end of the second path limiting member 50 in the length direction. The covering portion 51 has a receiving portion 60, a cover portion 70, and a joining portion 80 formed by the engagement of the receiving portion 60 and the cover portion 70 (see...). Figure 5 The cover 70 is, for example, a separate component from the receiving part 60. The path limiting part 52 is integrally formed with the receiving part 60. That is, the receiving part 60 and the path limiting part 52 are a single component.

[0050] The receiving portion 60, the cover portion 70, and the path limiting portion 52 constituting the second path limiting member 50 are made of, for example, metal or resin. In this embodiment, the receiving portion 60, the cover portion 70, and the path limiting portion 52 are made of resin. Synthetic resins such as polypropylene, polyamide, and polyoxymethylene can be used as materials for the receiving portion 60, the cover portion 70, and the path limiting portion 52. The second path limiting member 50 can be manufactured, for example, by a known manufacturing method such as injection molding.

[0051] (The structure of the path restriction unit 52) The path limiting portion 52 extends, for example, along the path of the curved portion 11B. That is, the path limiting portion 52 has a bent shape that follows the shape of the curved portion 11B. The path limiting portion 52, for example, partially covers the circumferential portion of the outer periphery of the outer member 30. The path limiting portion 52 is cylindrical in shape, partially covering the outer periphery of the outer member 30 in the circumferential direction. The path limiting portion 52, for example, covers half of the outer periphery of the outer member 30.

[0052] (Composition of the covering part 51) like Figure 3 As shown, the covering portion 51 is configured to overlap with the connecting portion 47 in the radial direction of the outer component 30, for example. That is, in the wire harness 10, in the length direction of the wire harness body 11, one end of the first path limiting member 40 in the length direction overlaps with one end of the second path limiting member 50 in the length direction.

[0053] The covering portion 51, for example, surrounds the outer periphery of the connecting portion 47 of the first path limiting member 40. The covering portion 51 is formed as a ring that surrounds the outer periphery of the connecting portion 47 and the outer periphery of the portion of the outer member 30 to which the connecting portion 47 is mounted, for example, throughout the entire circumference. The covering portion 51 extends along the path of the straight portion 11A, for example, and is formed as a shape that extends in a straight line in one direction.

[0054] like Figure 5 As shown, the receiving portion 60, for example, partially covers the circumferential periphery of the outer component 30. The receiving portion 60, for example, partially covers the circumferential periphery of the first path limiting member 40. The receiving portion 60 partially covers the circumferential periphery of the connecting portion 47 within the first path limiting member 40. The receiving portion 60 covers the outer periphery of the main body portion 41 within the connecting portion 47. The receiving portion 60 is cylindrical, partially covering the circumferential periphery of the first path limiting member 40. The receiving portion 60 covers half of the outer periphery of the first path limiting member 40. The receiving portion 60 is, for example, integrally formed as a semi-cylindrical shape. Figure 4 As shown, the receiving portion 60 is formed as a semi-cylindrical shape, for example, with an inner diameter larger than that of the path limiting portion 52. The cross-sectional shape of the inner surface of the receiving portion 60 is formed along the shape of the outer surface of the main body portion 41. The cross-sectional shape of the inner surface of the receiving portion 60 is formed as a semi-circular arc.

[0055] like Figure 5As shown, the receiving portion 60 has two ends 61, which are the two ends in the circumferential direction of the receiving portion 60. Each end 61 has a circumferential end face 61A of the receiving portion 60. The receiving portion 60 has, for example, a first fixing portion 62. The receiving portion 60 of this embodiment has two first fixing portions 62. The two first fixing portions 62 are each provided at the two ends 61. Each first fixing portion 62 protrudes radially outward from each end 61. The two first fixing portions 62 protrude in opposite directions in the radial direction of the covering portion 51. Each first fixing portion 62 protrudes in a direction away from the internal space of the covering portion 51. Each first fixing portion 62 is configured, for example, not to overlap with the insertion port 42 of the first path limiting member 40 housed inside the covering portion 51 in the radial direction of the covering portion 51. Figure 3 as well as Figure 4 As shown, each first fixing portion 62 extends, for example, along the length direction of the covering portion 51. Each first fixing portion 62 extends, for example, along the entire length direction of the covering portion 51. Each first fixing portion 62 has a first mating surface 63 extending radially along the covering portion 51. The first mating surface 63 is a plane continuous with the circumferential end face 61A of the receiving portion 60. The first mating surface 63 extends, for example, along the entire length direction of the covering portion 51.

[0056] like Figure 5 As shown, the cover portion 70 and the receiving portion 60 together cover the entire circumference of the first path limiting member 40. Specifically, the cover portion 70 and the receiving portion 60 together cover the outer circumference of the connecting portion 47 of the first path limiting member 40 throughout its entire circumference. In this embodiment, the cover portion 70 covers a portion of the outer circumference of the main body portion 41 of the connecting portion 47 and the portion of the outer circumference of the outer fitting member 30 exposed from the insertion port 42. The cover portion 70 is cylindrical, partially covering the outer circumference of the first path limiting member 40. The cover portion 70 covers half of the outer circumference of the first path limiting member 40. The cover portion 70 covers the portion of the outer circumference of the first path limiting member 40 not covered by the receiving portion 60, and covers half of the circumference of the first path limiting member 40. The cover portion 70 is, for example, integrally formed as a semi-cylindrical shape. The cover portion 70 is, for example, formed as a semi-cylindrical shape with the same inner diameter as the receiving portion 60. The cover portion 70 is, for example, formed as a semi-cylindrical shape with the same outer diameter as the receiving portion 60. The cross-sectional shape of the inner surface of the cover portion 70 is formed, for example, along the shape of the outer surface of the first path limiting member 40. The cross-sectional shape of the inner surface of the cover portion 70 is formed as a semi-circular arc.

[0057] The cover portion 70 has two ends 71, which are the two ends in the circumferential direction of the cover portion 70. Each end 71 has a circumferential end face 71A of the cover portion 70. The cover portion 70 has, for example, a second fixing portion 72. The cover portion 70 of this embodiment has two second fixing portions 72. The two second fixing portions 72 are each provided at the two ends 71. Each second fixing portion 72 is arranged to overlap with each first fixing portion 62. Each second fixing portion 72 protrudes radially outward from each end 71 towards the covering portion 51. The two second fixing portions 72 protrude in opposite directions in the radial direction of the covering portion 51. Each second fixing portion 72 protrudes in a direction that separates from the internal space of the covering portion 51. Each second fixing portion 72 is arranged, for example, not to overlap with the insertion port 42 of the first path limiting member 40 housed inside the covering portion 51 in the radial direction of the covering portion 51. Figure 3 As shown, each second fixing portion 72 extends, for example, along the length direction of the covering portion 51. Each second fixing portion 72 extends, for example, along the entire length of the covering portion 51. Each second fixing portion 72 has, for example, the same shape as each first fixing portion 62. Each second fixing portion 72 has a second mating surface 73 extending radially along the covering portion 51. The second mating surface 73 is a plane continuous with the circumferential end face 71A of the cover portion 70. Figure 5 As shown, each second mating surface 73 is disposed opposite to each first mating surface 63. Each second mating surface 73 is configured to contact each first mating surface 63 in a state of overlapping with each first mating surface 63.

[0058] The receiving portion 60 and the cover portion 70 are joined together such that the circumferential ends 61 of the receiving portion 60 overlap with the circumferential ends 71 ​​of the cover portion 70. The receiving portion 60 and the cover portion 70 are joined, for example, with the first fixing portion 62 overlapping the second fixing portion 72 and the first mating surface 63 overlapping the second mating surface 73. The first fixing portion 62 overlaps with the second fixing portion 72 in a direction orthogonal to the protruding direction (left-right direction in the figure) of the first fixing portion 62 (up-down direction in the figure). The receiving portion 60 and the cover portion 70 are joined, for example, by the first fixing portion 62 and the second fixing portion 72. The joining portion 80 formed by the joining of the first fixing portion 62 and the second fixing portion 72 is, for example, joined by welding the overlapping first fixing portion 62 and the second fixing portion 72. That is, the joining portion 80 is, for example, a welded portion formed by welding the first fixing portion 62 and the second fixing portion 72. As a welding method, known welding methods such as laser welding, arc welding, gas welding, and spot welding can be used. In the joint portion 80 of this embodiment, the overlapping first fixing portion 62 and the second fixing portion 72 are joined by spot welding. In addition, the joining method of the first fixing portion 62 and the second fixing portion 72 is not limited to welding, and can also be a joining method using, for example, adhesives.

[0059] In this embodiment, the joining portion 80 is only provided in the first fixing portion 62 and the second fixing portion 72 of the receiving portion 60 and the cover portion 70. That is, the joining portion 80 in this embodiment is not provided at the circumferential ends 61 of the receiving portion 60 and the circumferential ends 71 ​​of the cover portion 70. The joining portion 80 is configured, for example, not to overlap with the insertion port 42 of the first path limiting member 40 in the radial direction of the covering portion 51. The joining portion 80 is configured, for example, to overlap with the main body portion 41 of the first path limiting member 40 in the radial direction of the covering portion 51. The joining portion 80 is formed, for example, along the entire length of the covering portion 51. Through this joining portion 80, the receiving portion 60 and the cover portion 70 are fixed and cannot be disassembled, maintaining the fixed state of the receiving portion 60 and the cover portion 70. With the receiving portion 60 and the cover portion 70 fixed together by the joining portion 80, the covering portion 51 is in a ring shape that surrounds the outer circumference of the outer member 30 and the connecting portion 47. That is, in the covering portion 51, the receiving portion 60 and the cover portion 70 are held in a ring state by the joining portion 80. In this ring state, the receiving portion 60 and the cover portion 70 cover the outer circumference of the outer member 30 and the first path limiting member 40 throughout the entire circumference, and clamp the first path limiting member 40. In addition, the inner surface of the covering portion 51 in the ring state is, for example, in close contact with the outer surface of the first path limiting member 40. The inner surface of the covering portion 51 in the ring state presses the outer surface of the first path limiting member 40 radially inward toward the covering portion 51.

[0060] like Figure 6 As shown, an interference fit is provided, for example, between the inner periphery of the covering portion 51 and the outer periphery of the first path limiting member 40. For example, the minimum inner diameter d2 of the covering portion 51 is set to be smaller than the maximum outer diameter d1 of the first path limiting member 40 before it is inserted into the covering portion 51 when it is assembled to the outer periphery of the outer member 30. Here, in this embodiment, when the outer member 30 is inserted into the first path limiting member 40, the opening width of the insertion port 42 is the original width, that is, a width slightly larger than the width when the outer member 30 is not inserted. Specifically, in this embodiment, the outer diameter of the first path limiting member 40 when the outer member 30 is inserted into the covering portion 51 is larger than the outer diameter when the outer member 30 is not inserted by an amount corresponding to the protrusion amount of the protrusion 45. Therefore, the maximum outer diameter d1 of the first path limiting member 40 in this embodiment is the outer diameter of the portion of the first path limiting member 40 through which the protrusion 45 passes, in the state of being assembled to the outer periphery of the outer member 30 and inserted into the covering portion 51. Furthermore, in this embodiment, the minimum inner diameter d2 is the inner diameter of the covering portion 51 at the position corresponding to the maximum outer diameter d1. The minimum inner diameter d2 is, for example, set to be smaller than the maximum outer diameter d1 by an amount corresponding to the protrusion amount of the protrusion 45.

[0061] By setting the maximum outer diameter d1 and the minimum inner diameter d2 in this way, the first path limiting member 40, which is assembled to the outer periphery of the outer component 30, fits with an interference fit to the inner periphery of the covering portion 51. Figure 5 As shown, when the outer component 30 and the first path limiting member 40 are housed inside the covering portion 51, and the receiving portion 60 and the cover portion 70 remain in a ring-like state, the first path limiting member 40 is fitted and fixed to the inner circumference of the covering portion 51 with an interference fit. Thus, the inner circumferential surface of the covering portion 51 contacts the outer circumferential surface of the first path limiting member 40 with an interference fit. That is, the first path limiting member 40, fitted inside the covering portion 51, is held by the inner surface of the covering portion 51 in a state where it is always pressed radially inward towards the covering portion 51. Therefore, the wobbling of the first path limiting member 40 can be suppressed inside the covering portion 51.

[0062] The covering portion 51, for example, has a protrusion 75. The protrusion 75 protrudes from the inner surface of the covering portion 51 toward the insertion port 42 of the first path limiting member 40, which is inserted into the interior of the covering portion 51. The protrusion 75 protrudes in a manner that it is disposed inside the insertion port 42. The protrusion 75 is capable of contacting the first end 43 and the second end 44 in the circumferential direction of the first path limiting member 40. By engaging the protrusion 75 with the first end 43 or the second end 44, relative movement of the first path limiting member 40 relative to the covering portion 51 in the circumferential direction of the first path limiting member 40 is suppressed. Therefore, positional displacement of the first path limiting member 40 relative to the covering portion 51 in the circumferential direction of the first path limiting member 40 can be suppressed.

[0063] For example, a protrusion 75 is provided on the inner surface of the cover portion 70. The protrusion 75 protrudes from the inner surface of the cover portion 70 toward the receiving portion 60. Therefore, with the protrusion 75 disposed inside the insertion port 42, the insertion port 42 faces the cover portion 70 side of the covering portion 51.

[0064] like Figure 3 As shown, the protrusion 75 extends, for example, along the length direction of the wire harness body 11. The protrusion 75 extends, for example, along the entire length of the covering portion 51. The protrusion 75 is provided partially, for example, in the circumferential direction of the cover portion 70. The protrusion 75 is provided, for example, in the middle portion of the circumferential direction of the cover portion 70.

[0065] like Figure 7As shown, the protrusion 75 has a protrusion 76 that, for example, enters an annular recess 32 of the outer member 30. The protrusion 76 is configured to further protrude from the protruding top surface of the protrusion 75. Multiple protrusions 76 are provided in the longitudinal direction of the harness body 11. In this embodiment, four protrusions 76 are provided in the longitudinal direction of the harness body 11, each entering a different annular recess 32. By allowing the protrusions 76 to enter the annular recess 32, movement of the outer member 30 relative to the second path limiting member 50 in the longitudinal direction of the outer member 30 can be suppressed.

[0066] (The composition of limiting components 91 and 92) like Figure 2 As shown, the wire harness 10 has, for example, a limiting member 91 that restricts the movement of the first path limiting member 40 relative to the outer member 30. The wire harness 10 also has, for example, a limiting member 92 that restricts the movement of the second path limiting member 50 relative to the outer member 30. The limiting members 91 and 92 can be, for example, resin or metal strapping, rivet rings, and / or tape. In this embodiment, the limiting members 91 and 92 are tape.

[0067] The limiting member 91 is formed, for example, by fixing the end of the first path limiting member 40 located on the side opposite to the connecting portion 47 to the outer surface of the outer member 30. The limiting member 91, for example, extends from the outer surface of the end of the first path limiting member 40 in the longitudinal direction to the outer surface of the outer member 30. This suppresses movement of the first path limiting member 40 relative to the outer member 30 in the longitudinal and circumferential directions of the harness body 11. The limiting member 92 is formed, for example, by fixing the end of the second path limiting member 50 located on the side opposite to the covering portion 51 to the outer surface of the outer member 30. The limiting member 92, for example, extends from the outer surface of the end of the second path limiting member 50 in the longitudinal direction to the outer surface of the outer member 30. This suppresses movement of the second path limiting member 50 relative to the outer member 30 in the longitudinal and circumferential directions of the harness body 11.

[0068] Next, the function of this embodiment will be explained. Along the length of the wire harness body 11, the connecting portion 47 of the first path limiting member 40 overlaps with the covering portion 51 of the second path limiting member 50. At this time, within the covering portion 51, the outer periphery of the first path limiting member 40 is covered by a receiving portion 60 and a cover portion 70, which engage. Through the engagement of the receiving portion 60 and the cover portion 70, the receiving portion 60 and the cover portion 70 maintain a state of clamping the first path limiting member 40. Thus, the connection between the first path limiting member 40 and the second path limiting member 50 is maintained. As a result, the path of the wire harness body 11 is continuously limited by the first path limiting member 40 and the second path limiting member 50.

[0069] Next, the effects of this implementation method will be explained. (1) The covering portion 51 has: a receiving portion 60 that partially covers the circumferential direction of the first path limiting member 40; and a cover portion 70 that, together with the receiving portion 60, covers the outer periphery of the first path limiting member 40 throughout the entire circumference. Furthermore, the receiving portion 60 and the cover portion 70 are engaged with each other at the engagement portion 80. In this case, for example, compared to a configuration where the cover portion 70 is integrally formed on the receiving portion 60 via a thin-walled hinge portion, and the cover portion 70 is locked to the receiving portion 60 by the engagement of the claw portion in the closed state, the wobbling of the receiving portion 60 and the cover portion 70 can be suppressed. That is, in a configuration with a thin-walled hinge portion and a claw portion, wobbling of the receiving portion 60 and the cover portion 70 easily occurs at various points on the hinge portion and the claw portion; however, in a configuration where the receiving portion 60 and the cover portion 70 are engaged, such wobbling can be suppressed. Therefore, the first path limiting member 40 can be clamped securely by the receiving part 60 and the cover part 70 without wobbling, and the wobbling of the first path limiting member 40 and the second path limiting member 50 can be suppressed. As a result, for example, damage to the assembly part of the first path limiting member 40 and the second path limiting member 50 can be suppressed, and the path of the wire harness body 11 can be stably limited.

[0070] (2) The covering portion 51 is formed as a ring that surrounds the connecting portion 47 and the outer component 30 together by the receiving portion 60 and the cover portion 70. According to this structure, even though the covering portion 51 is formed as a ring surrounding the connecting portion 47 and the outer component 30, since the covering portion 51 is divided into the receiving portion 60 and the cover portion 70, the second path limiting member 50, including the covering portion 51, can be installed after the first path limiting member 40 and the outer component 30. As a result, the assembly workability of the wire harness 10 can be improved.

[0071] (3) The insertion port 42 of the first path limiting member 40 opens in a direction orthogonal to the length direction of the main body 41 and extends along the entire length of the main body 41. Therefore, after terminal processing such as assembling connectors C1 and C2 to the ends of the wire member 20 in the length direction, the first path limiting member 40 can be assembled relative to the outer member 30 through the insertion port 42. This allows for the subsequent installation of the first path limiting member 40, thus improving the assembly workability of the wire harness 10.

[0072] (4) The receiving part 60 and the cover part 70 are joined by welding. Therefore, the receiving part 60 and the cover part 70 can be joined without the use of adhesives or other components. Therefore, the number of parts in the covering part 51 can be prevented from increasing.

[0073] (5) A first fixing part 62 is provided, protruding radially outward from the circumferential end 61 of the receiving part 60, and a second fixing part 72 is provided, protruding radially outward from the circumferential end 71 of the cover part 70 and overlapping with the first fixing part 62. Furthermore, the first fixing part 62 and the second fixing part 72 are joined by welding. Therefore, the joining part 80, i.e., the welded part, can be positioned separately from the internal space of the covering part 51. Thus, the welded part can be positioned separately from the wire member 20 housed within the internal space of the covering part 51. Therefore, it is possible to appropriately suppress the application of energy (heat, etc.) from an energy source (heat source, etc.) to the welded part when welding, for example, the first fixing part 62 and the second fixing part 72, to the wire member 20. As a result, damage to the wire member 20 can be appropriately suppressed.

[0074] (6) The first fixing part 62 overlaps with the second fixing part 72 in a direction orthogonal to the protruding direction of the first fixing part 62. According to this structure, the first fixing part 62 and the second fixing part 72 overlap in a direction not facing the interior space of the covering part 51, and the overlapping first fixing part 62 and second fixing part 72 are welded together. Thus, for example, the energy applied to the welding portion from the energy source when welding the first fixing part 62 and the second fixing part 72 can be more appropriately suppressed from being applied to the wire member 20. As a result, damage to the wire member 20 can be further appropriately suppressed.

[0075] (7) The joint portion 80 and the insertion port 42 of the first path limiting member 40 are configured not to overlap radially in the covering portion 51. Therefore, the main body portion 41 of the first path limiting member 40 can be positioned between the wire harness body 11 and the joint portion 80 radially in the covering portion 51. As a result, for example, the main body portion 41 can absorb sputtering that may occur during welding, and thus, damage to the wire harness body 11 caused by sputtering can be appropriately suppressed.

[0076] (8) An interference fit is provided between the outer periphery of the first path limiting member 40 and the inner periphery of the covering portion 51. According to this structure, the first path limiting member 40 is fitted into the inner periphery of the covering portion 51 with an interference fit. That is, when the first path limiting member 40 is fitted into the interior of the covering portion 51, the outer peripheral surface of the first path limiting member 40 contacts the inner peripheral surface of the covering portion 51 with an interference fit. Thus, the first path limiting member 40 fitted into the interior of the covering portion 51 remains in a state where the inner surface of the covered portion 51 is always pressed radially inward towards the covering portion 51. Therefore, the wobbling of the first path limiting member 40 can be appropriately suppressed inside the covering portion 51. As a result, for example, damage to the assembly part of the first path limiting member 40 and the second path limiting member 50 can be suppressed, thereby stably limiting the path of the wire harness body 11. Furthermore, relative movement of the first path limiting member 40 relative to the covering portion 51 can be appropriately suppressed in the longitudinal direction of the wire harness body 11. As a result, in the length direction of the wire harness body 11, the positional displacement of the first path limiting member 40 relative to the covering portion 51 can be appropriately suppressed, and the detachment of the first path limiting member 40 from the covering portion 51 can be appropriately suppressed.

[0077] (9) The first path limiting member 40 and the second path limiting member 50 are partially overlapped along the length of the wire harness body 11. Specifically, along the length of the wire harness body 11, the connecting portion 47 at the end of the first path limiting member 40 and the covering portion 51 at the end of the second path limiting member 50 overlap. Therefore, the first path limiting member 40 and the second path limiting member 50 are connected along the length of the wire harness body 11. Thus, the path of the wire harness body 11 can be continuously limited by the first path limiting member 40 and the second path limiting member 50.

[0078] (10) The path of the straight portion 11A is restricted by the first path restricting member 40, and the path of the curved portion 11B is restricted by the second path restricting member 50. As a result, it is possible to prevent the path of the straight portion 11A and the path of the curved portion 11B from deviating from the desired path.

[0079] (11) The first path limiting member 40 has a protrusion 45 that protrudes from the inner surface of at least one of the first end 43 and the second end 44 and is capable of contacting the outer surface of the outer member 30. Through this protrusion 45, the outer member 30 can be pressed from, for example, the outside of the outer member 30. Therefore, the first path limiting member 40 can be appropriately prevented from disengaging from the outer member 30 that has passed through the insertion port 42.

[0080] (Other implementation methods) The above embodiments can be modified as follows. The above embodiments and the following variations can be combined with each other to the extent that they are not technically contradictory.

[0081] • The structure of the covering portion 51 in the above embodiment can be appropriately modified. For example, the covering portion 51 only needs to have a receiving portion 60, a cover portion 70 and a joining portion 80, and other structures are not particularly limited.

[0082] • In the receiving part 60 of the above embodiment, at least one of the two first fixing parts 62 may be omitted. • In the cover portion 70 of the above embodiment, at least one of the two second fixing portions 72 may be omitted.

[0083] ·For example Figure 8 As shown, the end faces 61A on both circumferential sides of the receiving portion 60 can be joined with the end faces 71A on both circumferential sides of the cover portion 70. In the joining portion 80 of this modification, the end faces 61A and 71A are joined by welding. In this case, it is preferable that the joining portion 80 does not overlap with the insertion port 42 of the first path limiting member 40 in the radial direction of the covering portion 51. In this modification, two first fixing portions 62 are omitted from the receiving portion 60, and two second fixing portions 72 are omitted from the cover portion 70. Therefore, it is possible to appropriately suppress the radial enlargement of the covering portion 51.

[0084] • In the above embodiment, an interference fit is provided between the inner periphery of the covering portion 51 and the outer periphery of the first path limiting member 40, but this is not a limitation. For example, it is possible to form a structure in which no interference fit is provided between the inner periphery of the covering portion 51 and the outer periphery of the first path limiting member 40.

[0085] • The structure of the receiving portion 60 in the above embodiment is not limited to a semi-cylindrical shape. The cross-sectional shape of the inner surface of the receiving portion 60 is not limited to a circular arc shape, but can be changed to, for example, a U-shape, an elliptical arc shape, etc.

[0086] • The structure of the cover portion 70 in the above embodiment is not limited to a semi-cylindrical shape. The cross-sectional shape of the inner surface of the cover portion 70 is not limited to an arc shape, but can be changed to, for example, a U-shape, an elliptical arc shape, etc.

[0087] • In the above embodiment, a protrusion 75 is provided on the inner surface of the cover portion 70, but it is not limited to this and can be provided on the inner surface of the receiving portion 60. In this case, if the protrusion 75 provided on the inner surface of the receiving portion 60 is inserted into the insertion port 42 of the first path limiting member 40, the circumferential position of the insertion port 42 on the first path limiting member 40 is positioned toward the receiving portion 60 in the covering portion 51.

[0088] • The protrusion 76 of the covering portion 51 can be omitted. • The protrusion 75 of the covering part 51 can be omitted. • The structure of the second path limiting member 50 in the above embodiment can be appropriately modified. For example, the second path limiting member 50 only needs to have a covering portion 51, and other structures are not particularly limited.

[0089] • The bending shape at path restriction section 52 can be appropriately changed. • The cross-sectional shape of the inner surface of the path limiting part 52 is not limited to a circular arc shape, but can be changed to, for example, a U-shape, an elliptical arc shape, etc.

[0090] • A cover that connects to the path restriction unit 52 can be installed. The second path limiting member 50 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 50 can be changed to a shape that limits the path of the straight portion 11A of the wire harness body 11. In this case, the second path limiting member 50 is formed such that, for example, the bending shape at the path limiting portion 52 is changed to a shape that extends in a straight line.

[0091] In the above embodiment, the assembly member having the covering portion 51 is specifically embodied as the second path limiting member 50, but it is not limited thereto. For example, the assembly member can be embodied as a structure having only the covering portion 51. For example, the assembly member can be embodied as a vehicle assembly member for assembling the first path limiting member 40 onto the vehicle V.

[0092] • The structure of the first path limiting member 40 in the above embodiment can be appropriately modified. For example, the first path limiting member 40 only needs to have an insertion port 42 and a structure that can be assembled to the outer periphery of the outer member 30; other structures are not particularly limited.

[0093] • The protrusions 45 of the above embodiments can be disposed in the circumferential direction of the first path limiting member 40 at a position farther away from the insertion port 42 than the first end 43 and the second end 44. • Each protrusion 45 may be provided locally along the length direction of the first path limiting member 40.

[0094] • At least one of the two protrusions 45 can be omitted. • In the first path limiting member 40, a second protrusion may be provided, protruding from the inner surface of the circumferential middle portion of the main body 41 and capable of contacting the outer surface of the outer member 30. According to this structure, both the protrusion 45 and the second protrusion can contact the outer surface of the outer member 30. Therefore, the swaying of the first path limiting member 40 can be suppressed.

[0095] • In the first path limiting member 40, a groove extending along the length direction can be provided on the outer surface of the main body 41. According to this structure, the main body 41 can be easily deformed outwards from the groove, thereby easily expanding the insertion port 42. As a result, the assemblability of the first path limiting member 40 is improved.

[0096] • The radial thickness of the main body 41 can vary in the circumferential direction. • The cross-sectional shape of the main body 41 is not limited to a circular arc shape, but can be changed to, for example, an elliptical arc shape, a U-shaped shape, etc.

[0097] In the above embodiment, the first path limiting member 40 and the second path limiting member 50 are harder than the outer member 30, but are not limited thereto; they may be of the same or lower hardness as the outer member 30. That is, as long as the first path limiting member 40 and the second path limiting member 50 function in a way that makes the wire harness body 11 difficult to bend compared to the state where the first path limiting member 40 and the second path limiting member 50 are not yet assembled, they may not be harder than the outer member 30.

[0098] • In the above embodiment, the second path limiting member 50 may be provided on both sides of the first path limiting member 40 in the length direction. • At least one of the limiting components 91 and 92 in the above embodiments can be omitted.

[0099] • 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 an annular protrusion 31 and an annular recess 32.

[0100] • 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.

[0101] 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.

[0102] • 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.

[0103] • 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.

[0104] The embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. The scope of the invention is not as described above, but is indicated by the scope of the claims, and is expected to include all modifications within the meaning and scope of the claims.
