[0021] [Description of embodiments of this disclosure]

[0022] First, the implementation methods of this disclosure are listed and explained.

[0023] The wire harness disclosed herein,

[0024] [1] The device comprises: a wire harness body having a wire member and an outer member covering the outer periphery of the wire member; a first 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 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 length direction of the first path limiting member, the assembly member having: a covering portion covering the outer periphery of the first path limiting member; and an elastic portion disposed in a compressed state between the covering portion and at least one of the first path limiting member and the outer member.

[0025] According to this structure, because it has an elastic portion that is configured in a compressed state between the covering portion that covers the outer periphery of the first path limiting member and at least one of the first path limiting member and the outer mounting member, the first path limiting member is held by the covering portion in a pressed state by the elastic portion. In this way, for example, compared to a structure where the covering portion is composed of a receiving portion and a cover, and the cover is integrally formed with the receiving portion by a thin-walled hinge portion, and the cover is locked to the receiving portion only by the engagement of a claw portion in the closed state, the wobbling of the covering portion and the first path limiting member can be suppressed. That is, in structures such as those with thin-walled hinge portions and claw portions, wobbling of the receiving portion and the cover occurs at various points of the hinge portion and the claw portion, resulting in a tendency for wobbling of the covering portion and the first path limiting member to occur, but this wobbling can be avoided. Therefore, the wobbling of the first path limiting member and the mounting member can be suppressed.

[0026] [2] Preferably, the elastic portion is provided in a plurality of portions in the circumferential direction of the covering portion.

[0027] According to this structure, since multiple elastic portions are provided circumferentially in the covering portion, the first path limiting member is held by the covering portion in a state where it is pressed by the elastic portions at multiple points. Therefore, for example, the shaking of the first path limiting member and the assembly member can be further suppressed.

[0028] [3] Preferably, the elastic part and the covering part are integrally molded articles made of the same material.

[0029] Because the elastic part and the covering part are integrally molded from the same material, the increase in the number of parts can be suppressed, and it can be easily manufactured.

[0030] [4] Preferably, the elastic portion constitutes an anti-rotation portion that prevents the first path limiting member from rotating relative to the covering portion in the circumferential direction by engaging with the insertion port in the circumferential direction of the first path limiting member.

[0031] According to this structure, the elastic part, because it constitutes an anti-rotation part, can prevent the first path limiting member from rotating circumferentially relative to the covering part.

[0032] [5] Preferably, the elastic part is made of metal.

[0033] According to this structure, since the elastic part is made of metal, it can, for example, press more firmly against at least one of the first path limiting member and the outer component.

[0034] [6] Preferably, the elastic part is a metal plate that can elastically deform into either a first state in which it flexes toward the radially outward side of the covering part or a second state in which it flexes toward the radially inward side of the covering part and maintains either state, wherein in the second state, it is disposed in a compressed state between the covering part and at least one of the first path limiting member and the outer member.

[0035] According to this structure, for example, it can be manufactured by elastically deforming the elastic part from the first state to the second state after the first path limiting member is disposed inside the covering part, making manufacturing easy.

[0036] [7] Preferably, the covering portion has: a receiving portion that covers a portion of the circumferential direction of the first path limiting member; and a cover that is fixed to the receiving portion and together with the receiving portion covers the entire circumference of the first path limiting member.

[0037] According to this structure, since the covering part has a receiving part and a cover, the covering part can be subsequently installed on the first path limiting member, for example. Therefore, compared to cases where the covering part is a non-deformable cylindrical shape, the assembly workability of the wire harness becomes better.

[0038] [8] Preferably, the assembly member is a second path limiting member assembled on the outer periphery of the outer component and limiting the path of the wire harness body, and the covering part is disposed at the end of the second path limiting member in the length direction, covering the outer periphery of the end of the first path limiting member in the length direction.

[0039] According to this structure, because the covering portion is located at the end of the second path limiting member in the longitudinal direction, covering the outer periphery of the end of the first path limiting member in the longitudinal direction, the first path limiting member and the second path limiting member are connected in the longitudinal direction. Therefore, the path of the wire harness body is continuously limited by the first path limiting member and the second path limiting member.

[0040] [9] Preferably, the first path limiting member limits the path of the straight portion, which is a straight part in the path of the wire harness body, and the second path limiting member limits the path of the bent portion, which is a bent part in the path of the wire harness body.

[0041] According to this structure, the path of the straight portion is restricted by a first path limiting member, and the path of the bent portion is restricted by a second path limiting member. Thus, deviations of the straight and bent portions of the wire harness from their desired paths can be continuously prevented.

[0042] [Details of the embodiments of this disclosure]

[0043] The following is a reference to the appendix. Figure 1 Specific examples of the wire harnesses disclosed herein will be described. In the accompanying drawings, for ease of explanation, sometimes a portion of the structure is shown enlarged or simplified. Furthermore, the dimensional ratios of the various parts may differ in the various drawings. The terms "parallel" and "orthogonal" in this specification include not only cases where they are strictly parallel or orthogonal, but also cases where they are substantially parallel or orthogonal to the extent that they achieve the desired effect in this embodiment. It should be noted that the invention is not limited to these examples, but is defined by the claims and includes all modifications within the meaning and scope equivalent to the claims.

[0044] (Overall structure of wire harness 10)

[0045] Figure 1 The wiring harness 10 shown is, for example, mounted on a vehicle V such as a hybrid vehicle or an electric vehicle. The wiring harness 10 electrically connects two or more on-board devices to each other. On-board devices are electrical devices mounted on the vehicle V. For example, the wiring harness 10 electrically connects an inverter M1 located at the front of the vehicle V and a high-voltage battery M2 located at the rear of the vehicle V, beyond the inverter M1. The wiring harness 10 is, for example, formed as a long strip extending in the longitudinal direction of the vehicle V. For example, the wiring harness 10 is laid out in the vehicle V such that its middle portion, along its length, passes under the floor of the vehicle V or outside the passenger compartment.

[0046] Inverter M1 is connected, for example, to an electric motor (not shown) that powers the drive wheels of the vehicle. Inverter M1 generates alternating current from the direct current (DC) of high-voltage battery M2 and supplies this AC power to the electric motor. High-voltage battery M2 is, for example, a battery capable of supplying several hundred volts.

[0047] 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.

[0048] like Figure 2 and 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 serving as a mounting member mounted on the outer periphery of the outer component 30. The first path limiting member 40 and the second path limiting member 60 limit the routing path of the wire harness body 11. It should be noted that... Figure 1 The illustrations of the first path limiting member 40 and the second path limiting member 60 are omitted.

[0049] (Structure of electrical component 20)

[0050] like Figure 4 and Figure 5 As shown, the wire member 20 has, for example, one or more wires 21, which are two wires in this embodiment, and a braided member 25 that surrounds the outer circumference of the multiple wires 21.

[0051] like Figure 5 As shown, each wire 21 is a covered wire having a core wire 22 and an insulating covering portion 23. The core wire 22 is conductive, and the insulating covering portion 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 and 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.

[0052] As the core wire 22, for example, a stranded wire composed of multiple metal wires twisted together or a single-core wire composed of a single conductor can be used. As a single-core wire, for example, a cylindrical conductor composed of a single metal rod with a solid internal structure or a cylindrical conductor with a hollow internal structure can be used. As the core wire 22, stranded wires, cylindrical conductors, and cylindrical conductors can also be used in combination. As the material of the core wire 22, for example, copper-based or aluminum-based metal materials can be used.

[0053] The insulating covering portion 23, for example, covers the entire circumference of the outer peripheral surface of the core wire 22. The insulating covering portion 23 is, for example, made of an insulating resin material.

[0054] The cross-sectional shape of each wire 21, which is the shape of the cross section formed by cutting the wire 21 using a plane orthogonal to the length direction of each wire 21, can be any shape. For example, the cross-sectional shape of each wire 21 can be formed as a circle, a semi-circle, a polygon, a square, a flat shape, etc. In this embodiment, the cross-sectional shape of each wire 21 is formed as a circle.

[0055] The braided member 25 is, for example, formed as a cylindrical shape that surrounds the outer circumference of the multiple wires 21. The braided member 25 can be, for example, a braided wire made of multiple metal wires, or a braided wire made of a combination of metal wires and resin wires. The material of the metal wires can be, for example, copper-based, aluminum-based, or other metal materials. Although not shown in the figure, the two ends of the braided member 25 in the longitudinal direction are, for example, at connectors C1 and C2 (see reference). Figure 1 Grounding in, etc.

[0056] (Structure of external component 30)

[0057] like Figure 4As shown, the outer casing 30 is formed as a cylinder that surrounds the entire circumference of the wire component 20. In this embodiment, the outer casing 30 is formed as a cylinder. For example, a circumferential wall is continuously formed throughout the entire circumference of the outer casing 30. For example, the outer casing 30 completely seals the interior circumferentially. For example, the outer casing 30 has the function of protecting the wire component 20 from flying objects and water droplets.

[0058] The outer component 30 is flexible and can be easily bent. Examples of flexible outer components 30 include resin corrugated tubes and rubber waterproof caps. The outer component 30 of this embodiment is a resin corrugated tube formed with corrugated sections of varying diameters repeatedly along its length. That is, the outer component 30 of this embodiment has a corrugated structure in which a large-diameter portion 31 and a small-diameter portion 32, smaller than the large-diameter portion 31, are alternately connected along the length of the outer component 30. The large-diameter portion 31 and the small-diameter portion 32 are each formed, for example, as an annulus around 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. It should be noted that... Figures 1-3 For the sake of simplicity in the accompanying drawings, the external component 30 is shown in a simplified manner.

[0059] (Structure of the first path limiting member 40 and the second path limiting member 60)

[0060] like Figure 2 and Figure 3 As 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, 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 rigidity that makes them less prone to bending in a direction orthogonal to the length direction of the wire harness body 11 compared to the outer member 30. Therefore, 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 so that the wire harness body 11 does not deviate from the desired path due to its own weight or the like.

[0061] like Figure 2As shown, the first path limiting member 40 is partially provided along the length of the wire harness body 11. The first path limiting member 40 is, for example, fitted to the outer periphery of the outer member 30 in the straight section 11A, which is a straight portion in the path of the wire harness body 11. The first path limiting member 40 restricts the path of the wire harness body 11 in the straight section 11A. Here, the straight section 11A is the portion of the wire harness body 11 whose path extends straight in one direction. It should be noted that one or more first path limiting members 40 are provided depending on the path of the wire harness body 11.

[0062] The second path limiting member 60 is partially provided along the length of the wire harness body 11. The second path limiting member 60 is, for example, fitted to the outer periphery of the outer component 30 at a bend 11B, which is a bent portion in the path of the wire harness body 11. The second path limiting member 60 restricts the path of the wire harness body 11 within the bend 11B. Here, the bend 11B is a portion of the wire harness body 11 whose path is bent away from a straight line. It should be noted that one or more second path limiting members 60 are provided depending on the path of the wire harness body 11.

[0063] (Structure of the first path restriction component 40)

[0064] 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 a shape that covers a portion of 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 an area larger than half the circumference of the outer member 30. That is, the first path limiting member 40 covers an area of ​​the outer periphery of the outer member 30 larger than half the total circumference of the outer member 30. Figure 2 As shown, the first path limiting member 40 extends along the length direction of the outer member 30 in the straight section 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.

[0065] 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 polyacetal can be used as the material for the first path limiting member 40. The first path limiting member 40 can be manufactured by known manufacturing methods such as extrusion molding and injection molding. In this embodiment, the first path limiting member 40 is an extruded article manufactured by extrusion molding. Therefore, the first path limiting member 40 can be easily manufactured by using an extrusion molding machine that extrudes the raw material of the first path limiting member 40 in the length direction. 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 using a cutting machine to cut the base material formed by a single extrusion molding machine to an arbitrary length, multiple first path limiting members 40 with different dimensions in the length direction can be manufactured.

[0066] 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 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 forming the insertion port 40X, the first end 41 and the second end 42 being the two circumferential ends of the first path limiting member 40. The first path limiting member 40 has a connecting portion 43 connecting the first end 41 and the second end 42. In other words, the first path limiting member 40 has: a connecting portion 43 formed in such a way as to cover a portion of the circumferential direction of the outer member 30; a first end 41 and a second end 42 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.

[0067] 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, arcuate.

[0068] The first end 41 and the second end 42 are disposed opposite to each other in the circumferential direction of the first path limiting member 40. The first end 41 and the second end 42 are disposed separately from each other in the circumferential direction of the first path limiting member 40 through 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 in a portion of the circumferential direction of the first path limiting member 40.

[0069] The top ends of the first end 41 and the second end 42 are formed into curved shapes. In this embodiment, the top ends of the first end 41 and the second end 42 are formed into arc shapes.

[0070] 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 an 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.

[0071] like Figure 3 As shown, each protrusion 45, 46 extends along the length of the first path limiting member 40. Each protrusion 45, 46 extends, for example, along the entire length of the first path limiting member 40.

[0072] Each protrusion 45, 46 presses against the outer component 30 from the outside. The outer component 30 is elastically held in place by the protrusions 45, 46, and the connecting portion 43. As a result, the connection between the first path limiting member 40 and the outer component 30 becomes secure.

[0073] 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 less than the outer diameter of the outer component 30.

[0074] 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 as 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. When the outer member 30 is inserted into the interior of 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 becomes smaller than the outer diameter of the outer member 30, and thus the first path limiting member 40 is fitted to the outer periphery of the outer member 30.

[0075] (Structure of the second path restriction component 60)

[0076] like Figure 2As shown, the second path limiting member 60 is fitted to the outer periphery of a portion 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 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 in the bend portion 11B. The second path limiting member 60 extends along the length of the outer member 30 in the bend portion 11B. The second path limiting member 60 is bent, for example, along the shape of the bend portion 11B.

[0077] The second path limiting member 60 has a second path limiting body 61 and a cover 62.

[0078] 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 polyacetal 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.

[0079] The second path limiting body 61 has a body portion 64 and a receiving portion 65. In this embodiment, the receiving portion 65 and the cover 62 constitute a covering portion 66.

[0080] The main body 64 covers a portion of the circumferential periphery of the outer component 30. The main body 64 is shaped to cover a portion of the circumferential periphery of the outer component 30. The cross-sectional shape of the main body 64 is generally formed as a semi-cylindrical shape. 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 in the bent portion 11B. The main body 64 is bent along the shape of the bent portion 11B.

[0081] A receiving portion 65 is provided at the longitudinal end of the second path limiting member 60 and at the longitudinal end of the main body portion 64. The receiving portion 65 covers a portion of the circumferential portion of the outer periphery of the first path limiting member 40. The receiving portion 65 covers a portion of the circumferential portion of the longitudinal end of the first path limiting member 40. The receiving portion 65 is shaped to cover a portion of the circumferential portion of the first path limiting member 40. The cross-sectional shape of the receiving portion 65 is generally formed as a semi-cylindrical shape. The receiving portion 65 is formed as a semi-cylindrical shape with a diameter larger than the diameter of the main body portion 64. The receiving portion 65 covers half of the outer periphery of the first path limiting member 40.

[0082] The receiving portion 65 and the cover 62 are integrally molded articles made of the same material. That is, the second path limiting member 60 of this embodiment is an integrally molded article including the second path limiting body 61 and the cover 62, both made of the same material. The cover 62 is connected to the receiving portion 65 by a thin-walled hinge portion 67. Specifically, the other end of the cover 62 is connected to one circumferential end of the receiving portion 65 by a thin-walled hinge portion 67. The cover 62 can rotate relative to the receiving portion 65 about the hinge portion 67. The covering portion 66 can be deformed 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. In the closed state, the covering portion 66 covers the outer periphery of the first path limiting member 40.

[0083] 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. The cover 62 is fixed to the receiving portion 65 without rotation by the engagement of the claw portion 68 and the engaged portion 69. Specifically, the receiving portion 65 and the cover 62 cannot rotate relative to each other when the claw portion 68 engages with the engaged portion 69, and the covering portion 66 remains in the closed state.

[0084] The cover 62, together with the receiving portion 65, completely covers the circumference of the first path limiting member 40. Specifically, with the covering portion 66 closed, the cover 62, together with the receiving portion 65, completely covers the circumferential direction along the outer periphery of the first path limiting member 40. In this embodiment, the cover 62 covers a portion of the outer periphery of the first path limiting member 40 and the portion of the outer periphery of the outer fitting member 30 exposed from the insertion opening 40X. 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 periphery of the first path limiting member 40 that is not covered by the receiving portion 65, and half of the circumferential direction along the outer periphery of the first path limiting member 40.

[0085] like Figure 5 As shown, the second path limiting member 60 has elastic portions 70 and 71, which are arranged in a compressed state between the covering portion 66 and at least one of the first path limiting member 40 and the outer member 30.

[0086] In detail, multiple elastic portions 70 and 71 are provided circumferentially around the covering portion 66. There are two elastic portions 70 and 71. One elastic portion 70 is provided in the receiving portion 65. The other elastic portion 71 is provided in the cover 62. The elastic portions 70 and 71 are provided at 180° intervals circumferentially around the covering portion 66. One elastic portion 70 is located at the center of the circumferential direction of the receiving portion 65. The other elastic portion 71 is located at the center of the circumferential direction of the cover 62. Figure 4 As shown, elastic portions 70 and 71 are disposed at the center of the covering portion 66 along its length. The elastic portions 70 and 71, the covering portion 66, the receiving portion 65, and the cover 62 are integrally molded articles made of the same material.

[0087] One elastic portion 70 is a pair of elastic sheets that extend from the circumferential center of the inner surface of the receiving portion 65 towards both circumferential ends and protrude radially inward towards the receiving portion 65. The other elastic portion 71 is a pair of elastic sheets that extend from the circumferential center of the inner surface of the cover 62 towards both circumferential ends and protrude radially inward towards the cover 62. Furthermore, the elastic portions 70 and 71 are thinner towards their protruding tips. One elastic portion 70 and the other elastic portion 71 have the same shape in a unloaded state and without deflection. It should be noted that the receiving portion 65 and the cover 62 have demolding holes 72 at the locations corresponding to the elastic portions 70 and 71, facilitating manufacturing using a mold.

[0088] Furthermore, the other elastic portion 71 constitutes an anti-rotation portion that prevents the first path limiting member 40 from rotating relative to the cover portion 66 in the circumferential direction by engaging with the insertion port 40X in the circumferential direction of the first path limiting member 40. When the cover portion 66 is changed from the open state to the closed state, the other elastic portion 71 moves along the outer periphery of the outer member 30 with its tip portion until it reaches the insertion port 40X, thereby engaging with the insertion port 40X in the circumferential direction of the first path limiting member 40. It should be noted that the other elastic portion 71 is difficult to further flex when its tip portion engages with the insertion port 40X, therefore, in the closed state of the cover portion 66, the first elastic portion 70 flexes more than the other elastic portion 71. In the closed state of the cover portion 66, the first elastic portion 70 is disposed in a compressed state between the receiving portion 65 and the first path limiting member 40. In the closed state of the cover portion 66, the other elastic portion 71 is disposed in a compressed state between the cover 62 and the outer member 30.

[0089] In addition, such as Figure 2As shown, the wire harness 10, for example, has a sliding limiting member 73, which limits 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, which limits 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, fastening rings, adhesive tape, etc., can be used, for example. In this embodiment, the sliding limiting members 73 and 74 are adhesive tape. The sliding limiting member 73 is wound around the end of the first path limiting member 40 that is not connected to the second path limiting member 60 and the outer member 30. The sliding limiting member 74 is wound around the end of the second path limiting member 60 that is not connected to the first path limiting member 40 and the outer member 30.

[0090] Next, the function of this embodiment will be explained.

[0091] The elastic portions 70 and 71 are disposed in a compressed state between the covering portion 66 of the second path limiting member 60 and at least one of the first path limiting member 40 and the outer fitting member 30. Therefore, the receiving portion 65 and the cover 62 constituting the covering portion 66 can maintain the state in which the first path limiting member 40 is clamped. Therefore, the connection between the first path limiting member 40 and the second path limiting member 60 can be maintained. Therefore, the path of the wire harness body 11 can be continuously limited.

[0092] Next, the effects of the above-described embodiments will be described.

[0093] (1) The cover has elastic portions 70 and 71, which are arranged in a compressed state between the covering portion 66 that covers the outer periphery of the first path limiting member 40 and at least one of the first path limiting member 40 and the outer member 30. Therefore, the first path limiting member 40 is held by the covering portion 66 in a pressed state by the elastic portions 70 and 71. In this way, for example, compared with a structure in which the cover 62 is integrally formed with the receiving portion 65 by the 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 covering portion 66 and the first path limiting member 40 can be suppressed. That is, in a structure such as the one with the thin-walled hinge portion 67 and the claw portion 68, the receiving portion 65 and the cover 62 shake at various parts of the hinge portion 67 and the claw portion 68, which makes it easy for the covering portion 66 and the first path limiting member 40 to shake, but this shaking can be avoided. Therefore, 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.

[0094] (2) Because multiple elastic portions 70 and 71 are provided circumferentially in the covering portion 66, the first path limiting member 40 is held in place by the covering portion 66 in a state where it is pressed by the elastic portions 70 and 71 at multiple points. Therefore, for example, the swaying of the first path limiting member 40 and the second path limiting member 60 can be further suppressed.

[0095] (3) Because the elastic parts 70, 71 and the covering part 66 are integrally molded products made of the same material, the increase in the number of parts can be suppressed and they can be easily manufactured.

[0096] (4) Because the elastic part 71 constitutes an anti-rotation part, it can prevent the first path limiting member 40 from rotating relative to the covering part 66 in the circumferential direction.

[0097] (5) Because the covering part 66 has a structure with a receiving part 65 and a cover 62, the covering part 66 can be subsequently installed on the first path limiting member 40. As a result, the assembly workability of the wire harness 10 becomes better, for example, compared to the case where the covering part 66 is a non-deformable cylindrical shape.

[0098] (6) 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, since the covering portion 66 is fitted to the longitudinal end of the second path limiting member 60, covering the outer periphery of the longitudinal end of the first path limiting member 40, the first path limiting member 40 and the second path limiting member 60 are connected in the longitudinal direction. Therefore, the path of the wire harness body 11 is continuously limited by the first path limiting member 40 and the second path limiting member 60.

[0099] (7) 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 bent 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 bent portion 11B of the wire harness body 11 can be continuously prevented from deviating from the desired paths.

[0100] (Other implementation methods)

[0101] The above embodiments can be implemented with the following modifications. The above embodiments and the following modifications can be combined with each other within the scope of technical inconsistency.

[0102] • In the above embodiment, the elastic portions 70 and 71 are a pair of elastic sheets protruding radially inward toward the covering portion 66, but they can also be changed to other shapes.

[0103] For example, you can also press Figure 6The modification is shown. In this example, one elastic portion 80 is thinner than other portions of the receiving portion 65 and protrudes while bending from the circumferential center of the receiving portion 65 toward the radially inward side of the receiving portion 65. Similarly, the other elastic portion 81 is thinner than other portions of the cover 62 and protrudes while bending from the circumferential center of the cover 62 toward the radially inward side of the cover 62. Both elastic portions 80 and 81 have the same shape in a unloaded and non-deflected state. The receiving portion 65 and the cover 62 have demolding holes 82 at locations corresponding to the elastic portions 80 and 81, facilitating manufacturing using a mold. Furthermore, one elastic portion 80 is disposed in a compressed state between the receiving portion 65 and the first path limiting member 40. The other elastic portion 81 is disposed in a compressed state between the cover 62 and the outer member 30. Even so, the wobbling of the first path limiting member 40 and the second path limiting member 60 can be suppressed.

[0104] • In the above embodiment, the elastic parts 70 and 71 and the covering part 66 are made of the same material and are integrally molded, but it is not limited to this. For example, they can be made of different materials from the covering part 66, or they can be separate from the covering part 66.

[0105] For example, you can also press Figure 7 The change shown is as follows. In this example, the elastic part 83 is made of metal. The elastic part 83 is a metal plate that can elastically deform into either a first state P1 in which it flexes radially outward toward the covering part 66 and a second state P2 in which it flexes radially inward toward the covering part 66, and maintain either state. That is, when an external force is applied to the elastic part 83 radially outward toward the covering part 66 in the second state P2, it becomes the first state P1 in which it flexes radially outward toward the covering part 66 and maintains that state. In addition, when an external force is applied to the elastic part 83 radially inward toward the covering part 66 in the first state P1, it becomes the second state P2 in which it flexes radially inward toward the covering part 66 and maintains that state. For example, the elastic part 83 is formed in the first state P1 when the covering part 66 is in the open state, and in the second state P2 when the covering part 66 is in the closed state. Thus, in the second state P2, the elastic portion 83 is disposed in a compressed state between the covering portion 66 and at least one of the first path limiting member 40 and the outer member 30. In this example, the elastic portion 83 is provided on the cover 62 and disposed in a compressed state between the covering portion 66 and the outer member 30. In addition, in this example, the elastic portion 83 is formed with the cover 62 as an insert, with both ends embedded in the cover 62.

[0106] In this way, since the elastic part 83 is made of metal, at least one of the first path limiting member 40 and the outer member 30 can be pressed more strongly. In addition, for example, the manufacturing of the wire harness 10 is made easier by elastically deforming the elastic part 83 from the first state P1 to the second state P2 after the first path limiting member 40 is disposed inside the covering part 66.

[0107] Alternatively, for example, you can press Figure 8 The changes shown are as follows. In this example, the elastic parts 84 and 85 are made of rubber. In this example, one elastic part 84 is located between the receiving part 65 and the first path limiting member 40, and is configured in a compressed state. In this example, the other elastic part 85 is located between the cover 62 and the outer member 30, and is configured in a compressed state. Even so, the swaying of the first path limiting member 40 and the second path limiting member 60 can be suppressed. It should be noted that the elastic parts 84 and 85 can also be changed to, for example, metal leaf springs, compression coil springs, etc.

[0108] • In the above embodiment, two elastic portions 70 and 71 are provided in the circumferential direction of the covering portion 66, but it is not limited to this and can be changed to provide one or more structures.

[0109] • In the above embodiment, the elastic part 71 is configured as an anti-rotation part that engages with the insertion port 40X in the circumferential direction of the first path limiting member 40, but it is not limited to this and may also be configured as a structure that does not engage with the insertion port 40X.

[0110] In the above embodiment, the covering portion 66 is designed to have a receiving portion 65 and a cover 62, but it is not limited to this. For example, the covering portion 66 may be modified to be a cylindrical structure that cannot be disassembled or deformed. In addition, the receiving portion 65 and the cover 62 are designed to be integrally formed with the receiving portion 65 by means of a thin-walled hinge portion 67, and the cover 62 and the receiving portion 65 are locked together by means of the engagement of the claw portion 68 in the closed state. However, it may also be modified to have the receiving portion 65 and the cover 62 fixed by other structures.

[0111] The second path limiting member 60 in the above embodiment is formed to limit the path of the bent portion 11B of the wire harness body 11, but it is not limited thereto. For example, the second path limiting member 60 may 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 60 may, for example, change the bent shape in the body portion 64 to a shape that extends in a straight line.

[0112] 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 it is not limited thereto. For example, the assembly member may also be embodied as a vehicle assembly member for assembling the first path limiting member 40 to the vehicle V.

[0113] • 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.

[0114] Alternatively, the protrusion 45 of the above embodiment can be provided at a position on the circumferential direction of the first path limiting member 40 that is farther from the insertion port 40X than the top end of the first end 41.

[0115] Alternatively, the protrusion 46 of the above embodiment can be provided at a position on the first path limiting member 40 that is farther from the insertion port 40X than the top of the second end 42 in the circumferential direction.

[0116] Alternatively, the protrusions 45 and 46 of the above embodiments may be partially provided in the length direction of the first path limiting member 40.

[0117] • At least one of the protrusions 45 and 46 in the above embodiments may also be omitted.

[0118] • In the first path limiting member 40 of the above embodiment, the radial thickness of the connecting portion 43 may also be configured to change in the circumferential direction.

[0119] • 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, a U-shaped shape, etc.

[0120] 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 are not limited thereto; they may also be of equal or less hardness to the outer member 30. That is, the first path limiting member 40 and the second path limiting member 60 only need to function in a way that makes the wire harness body 11 less prone to bending than the wire harness body 11 without the first path limiting member 40 and the second path limiting member 60.

[0121] • The external component 30 in the above embodiment may also be an external component in which a metal layer containing a metal material is provided on the outer surface of a resin bellows.

[0122] • The external component 30 of the above embodiments is not limited to a bellows, and may also be an external component without a large diameter portion 31 and a small diameter portion 32.

[0123] • The outer component 30 in the above embodiment may also be an outer component having a slit extending in the length direction of the outer component 30.

[0124] • In the above embodiment, the wire 21 is set as a high-voltage wire, but it is not limited to this. For example, the wire 21 can also be set as a low-voltage wire.

[0125] 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 also be embodied as a metal foil.

[0126] • The braided component 25 in the wire component 20 of the above embodiment can also be omitted.

[0127] In the above embodiment, two wires 21 constituting the wire member 20 are provided, but it is not limited to this. The number of wires 21 can be one or more.

[0128] • 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 modified according to the vehicle structure.

[0129] 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 are not particularly limited as long as they are electrical devices mounted on the vehicle V.

[0130] The embodiments disclosed herein should be considered illustrative in all respects, and not restrictive. The scope of the invention is defined not by the foregoing, but by the claims, and includes all modifications within the meaning and scope of the claims.
