Description

Technical Field

[0001] This disclosure relates to wire harnesses. Background Technology

[0002] For example, the wiring harness in Patent Document 1 includes a fixing member for securing a wire component to a vehicle body. This fixing member has a holding portion for holding the wire component and a bolt fixing portion for fixing to a bolt disposed on the vehicle body. The bolt fixing portion has locking tabs that lock relative to the threaded portion of the bolt in the axial direction. At least one pair of locking tabs are provided such that they clamp the bolt in an orthogonal axial direction. When assembling the fixing member to the bolt, the bolt is inserted into the fixing member. At this time, each locking tab flexes in a direction of separation from each other by being pressed by the bolt. Furthermore, each locking tab exerts force towards the bolt side through its own elasticity, locking with the threaded portion of the bolt.

[0003] Furthermore, the bolt fixing part has a force-applying part that elastically contacts the panel of the vehicle body and applies a force to the panel. In the fixing member of Patent Document 1, a spring plate serving as a force-applying part is provided near the bolt insertion port. The spring plates are arranged in pairs on both sides of the bolt when viewed orthogonally to the bolt axis. Each pair of spring plates extends from the side of the bolt fixing part opposite to the panel and extends separately from each other. The tip of each spring plate is a free end, located away from the side of the bolt fixing part. By applying a force to the panel from each spring plate, the wobbling of the fixing member can be suppressed.

[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 component having a wire; and a fixing member for fixing the wire component to an assembly object, the fixing member having: a bolt fixing portion for fixing to a bolt on the assembly object; and a retaining portion for retaining the wire component, the bolt fixing portion having: a side surface opposite to the assembly object; a bolt insertion port provided on the side surface for inserting the bolt; a locking portion for locking in the axial direction relative to the bolt inserted from the bolt insertion port into the bolt fixing portion; and a force-applying portion provided on the side surface and in contact with the assembly object, the force-applying portion having a pair of elastic plates extending from the side surface, the pair of elastic plates being inclined such that they move closer to each other as they move away from the side surface, the tips of the pair of elastic plates facing each other.

[0025] According to this structure, the tips of a pair of elastic plates in the force-applying part face each other. Therefore, for example, during the handling of a single fixing member or during the assembly of a wiring harness including the fixing member into a vehicle, snagging of the tips of the elastic plates can be suppressed. Thus, damage to the elastic plates in the force-applying part can be prevented.

[0026] [2] The force-applying part has a connecting part that connects the top ends of the pair of elastic sheets to each other.

[0027] According to this structure, the rigidity of each elastic sheet is improved by connecting the tips of the two elastic sheets together. Furthermore, by connecting the tips of the two elastic sheets together, the snagging of the tips of the elastic sheets can be suppressed. Therefore, damage to the elastic sheets can be further suppressed.

[0028] [3] The thickness of the connecting part is thinner than the thickness of each elastic sheet.

[0029] According to this structure, the flexibility of each elastic sheet can be ensured, and a connecting part can be formed to connect the top ends of each elastic sheet to each other.

[0030] [4] The wire harness disclosed herein comprises: a wire member having a wire; and a fixing member for fixing the wire member to an assembly object, the fixing member having: a bolt fixing portion for fixing to a bolt on the assembly object; and a retaining portion for retaining the wire member, the bolt fixing portion having: a side surface facing the assembly object; a bolt insertion port provided on the side surface for inserting the bolt; a locking portion for locking in the axial direction relative to the bolt inserted from the bolt insertion port into the bolt fixing portion; and a force-applying portion provided on the side surface and in contact with the assembly object, the force-applying portion having: a first connecting end connected to the side surface; a second connecting end connected to the side surface; and an elastic portion for connecting the first connecting end and the second connecting end and in contact with the assembly object to apply force to the assembly object.

[0031] According to this structure, the force-applying part has a free end that is not connected to the side of the bolt fixing part. Therefore, for example, during the handling of the fixing member unit or during the assembly of the wiring harness including the fixing member into a vehicle, snagging of the force-applying part can be suppressed. As a result, damage to the force-applying part can be prevented.

[0032] [5] The elastic part is formed as an arc shape that convexes to the side protruding from the side.

[0033] According to this structure, the elastic part can be used to apply appropriate force to the assembled object.

[0034] [6] The device comprises: an outer casing member that covers the outer periphery of the wire component; and a path limiting member that is fitted onto the outer periphery of the outer casing member to limit the path of the outer casing member, the path limiting member having an insertion port that opens in a direction orthogonal to the length direction of the path limiting member and extends integrally throughout the length direction of the path limiting member. According to this structure, damage to the force-applying portion of the bolt fixing part can be suppressed in a wire harness equipped with the path limiting member.

[0035] [7] The retaining portion holds the path limiting member in such a way that it covers the entire circumference of the path limiting member. The retaining portion has a protrusion that protrudes inward to the circumferential side, the protrusion being located inside the insertion port of the path limiting member. According to this structure, the path limiting member can be restricted from rotating relative to the retaining portion by means of the protrusion of the retaining portion.

[0036] [Details of the embodiments of this disclosure]

[0037] The following is a reference to the appendix. Figure 1Specific examples of the wiring 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 accompanying drawings. Additionally, the term "orthogonal" in this specification includes not only strictly orthogonal cases but also cases that are substantially orthogonal to the extent that they serve the functions and effects of this embodiment.

[0038] It should be noted that, in this specification, "opposite" refers to a position where surfaces or components are directly opposite each other, including not only positions where they are completely opposite each other, but also positions where they are partially opposite each other. Furthermore, "opposite" in this specification includes both cases where a component independent of the two parts is interposed between the two parts, and cases where nothing is interposed between the two parts.

[0039] (Overall structure of wire harness 10)

[0040] 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.

[0041] 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.

[0042] The wiring harness 10 has a wiring harness body 11. The wiring harness body 11 has a wire member 20 and a cylindrical outer casing 30 covering the outer periphery of the wire member 20. The wiring harness 10 has connectors C1 and C2 fitted to both ends of the wire member 20. One end of the wire member 20 in the longitudinal direction is connected to the inverter M1 via connector C1, and the other end of the wire member 20 in the longitudinal direction is connected to the high-voltage battery M2 via connector C2.

[0043] (Structure of electrical component 20)

[0044] like Figure 2 and Figure 3 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.

[0045] like Figure 2 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.

[0046] 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.

[0047] The insulating covering portion 23, for example, covers the entire circumference of the outer periphery of the core wire 22. The insulating covering portion 23 is, for example, made of an insulating resin material.

[0048] The cross-sectional shape of each wire 21, which is the shape of the cross section formed by cutting the wire 21 with 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.

[0049] 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.

[0050] (Structure of external component 30)

[0051] like Figure 3 As 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.

[0052] 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 with a diameter 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 that wraps around the circumference of the outer component 30. As the material of the outer component 30, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used.

[0053] (Structure of path restriction component 40)

[0054] like Figure 2 and Figure 3 As shown, the wiring harness 10 includes a path limiting member 40 mounted on the outer periphery of the outer component 30. The path limiting member 40 limits the routing path of the wiring harness body 11. It should be noted that... Figure 1 The diagram of path restriction component 40 is omitted.

[0055] The path limiting member 40 holds the outer component 30. The path limiting member 40 is, for example, more rigid than the outer component 30. The path limiting member 40 has a rigidity that makes it less prone to bending in a direction orthogonal to the length direction of the wire harness body 11 compared to the outer component 30. Thus, the path limiting member 40 restricts the path of the wire harness body 11. For example, the path limiting member 40 assists the outer component 30 so that the wire harness body 11 does not deviate from the desired path due to its own weight or the like. The path limiting member 40 is partially provided along the length direction of the wire harness body 11. For example, a straight portion 11A of the path limiting member 40, which is straight in the path of the wire harness body 11, is fitted to the outer periphery of the outer component 30.

[0056] like Figure 2 As shown, the path limiting member 40 covers a portion of the circumferential periphery of the outer member 30. The path limiting member 40 is a shape that encloses a portion of the circumferential periphery of the outer member 30. The cross-sectional shape of the path limiting member 40 is generally C-shaped. For example, the path limiting member 40 covers an area larger than half the circumference of the outer member 30. That is, the path limiting member 40 covers an area of ​​the outer periphery of the outer member 30 larger than half the full circumference of the outer member 30.

[0057] The path limiting member 40 extends along the length direction of the outer member 30 in the straight section 11A. The path limiting member 40 is formed, for example, in a shape that extends in a straight line in one direction. The cross-sectional shape of the path limiting member 40 is, for example, the same throughout the entire length direction of the path limiting member 40.

[0058] The path limiting member 40 is made of, for example, metal or resin. In this embodiment, the 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 path limiting member 40. The path limiting member 40 can be manufactured, for example, by known manufacturing methods such as extrusion molding or injection molding. In this embodiment, the path limiting member 40 is an extruded article manufactured by extrusion molding. Therefore, the path limiting member 40 can be easily manufactured by using an extrusion molding machine that extrudes the raw material of the path limiting member 40 in the length direction. Furthermore, multiple 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 parent material of the path limiting member 40 formed by a single extrusion molding machine to an arbitrary length, multiple path limiting members 40 with different dimensions in the length direction can be manufactured.

[0059] The path limiting member 40 has an insertion port 40X that opens in a direction orthogonal to the length direction of the path limiting member 40. The insertion port 40X extends throughout the length direction of the path limiting member 40. The path limiting member 40 has a first end 41 and a second end 42 forming the insertion port 40X, which are the two circumferential ends of the path limiting member 40. The path limiting member 40 has a connecting portion 43 that connects the first end 41 and the second end 42. In other words, the path limiting member 40 has: a connecting portion 43 formed in such a way that it covers 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.

[0060] The connecting portion 43 constitutes a major part of the path limiting member 40. The radial thickness of the connecting portion 43 is the same in the circumferential direction of the 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, arc-shaped.

[0061] The first end 41 and the second end 42 are disposed opposite to each other in the circumferential direction of the 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 path limiting member 40 through an insertion opening 40X. In other words, the gap between the first end 41 and the second end 42 in the circumferential direction of the path limiting member 40 forms the insertion opening 40X. Thus, the path limiting member 40 is formed in a C-shape with the insertion opening 40X in a portion of the circumferential direction of the path limiting member 40.

[0062] 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.

[0063] The path limiting member 40 has a protrusion 45 protruding from the inner surface of the first end 41 and a protrusion 46 protruding from the inner surface of the second end 42. Each protrusion 45, 46 protrudes toward the outer component 30 inserted into the path limiting member 40 and contacts the outer surface of the outer component 30. Each protrusion 45, 46 contacts the outer surface of the large-diameter portion 31 of the outer component 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.

[0064] like Figure 3 As shown, each protrusion 45, 46 extends along the length of the path limiting member 40. Each protrusion 45, 46 extends, for example, along the entire length of the path limiting member 40.

[0065] 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 path limiting member 40 and the outer component 30 becomes secure.

[0066] like Figure 2 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.

[0067] The opening width of the insertion port 40X increases due to the elastic deformation of the 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 path limiting member 40. When the outer member 30 is inserted into the path limiting member 40, the 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 path limiting member 40 is fitted to the outer periphery of the outer member 30.

[0068] (Structure of fixed component 50)

[0069] like Figure 2 As shown, the wiring harness 10 includes a fixing member 50 for fixing the wiring harness body 11 to the panel P of the floor portion constituting the vehicle V. One or more fixing members 50 are provided along the length of the wiring harness body 11. It should be noted that... Figure 1 The diagram of the fixing member 50 is omitted. The fixing member 50 holds a portion of the wire harness body 11, for example, that is fitted by the assembly path limiting member 40.

[0070] The fixing member 50 is made of, for example, metal or resin. In this embodiment, the fixing member 50 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used as the material for the fixing member 50. The fixing member 50 can be manufactured, for example, by known manufacturing methods such as injection molding.

[0071] like Figure 2 and Figure 3 As shown, the fixing member 50 has a bolt fixing part 51 that is fixed to a bolt B extending from the panel P, and a holding part 52 that holds the wire harness body 11.

[0072] (Structure of retaining part 52)

[0073] The retaining part 52 retains the path limiting member 40 in such a way that it covers the entire circumference of the path limiting member 40. The retaining part 52 has a retaining part body 53 and a cover part 54 connected to the retaining part body 53.

[0074] The retaining body 53, for example, covers the outer periphery of the connecting portion 43 in the path limiting member 40. The retaining body 53 has an insertion port 55 covered by a cover portion 54. The insertion port 55 opens in a direction orthogonal to the length direction of the wire harness body 11. It should be noted that the cross-sectional shape of the inner surface of the cover portion 54 is formed, for example, along the shape of the outer surface of the outer member 30.

[0075] The cover 54 is integrally formed with the retaining body 53, for example. The cover 54 is connected to the retaining body 53, for example, by a hinge 56. The cover 54 can rotate between an open position and a closed position covering the insertion port 55, about the hinge 56. It should be noted that... Figure 2 The cover 54 shown is in the closed position. Figure 3 The cover 54 shown is in the open position.

[0076] Additionally, the cover 54 has a locking claw 57. The locking claw 57 engages with the locking portion 58 provided on the retaining portion body 53 when the cover 54 is in the closed position. Thus, the cover 54 is held in the closed position. It should be noted that the wire harness body 11 is held in the retaining portion 52 with the insertion port 40X facing the cover 54.

[0077] like Figure 2 and Figure 3 As shown, the retaining portion 52 has a protrusion 59 protruding inward to the inner peripheral side, i.e., to the wire harness body 11 side. The protrusion 59 is formed in the retaining portion 52 in a manner that, for example, protrudes from the inner surface of the cover portion 54. One or more protrusions 59 are provided.

[0078] With the cover 54 in the closed position, the protrusion 59 is located inside the insertion opening 40X of the path limiting member 40. Therefore, the protrusion 59 can be used to restrict the path limiting member 40 from rotating relative to the retaining portion 52. Furthermore, the protrusion 59 engages with the small-diameter portion 32 of the outer member 30. Therefore, movement of the outer member 30 relative to the retaining portion 52 can be suppressed in the longitudinal direction of the outer member 30.

[0079] (Structure of bolt fixing part 51)

[0080] The bolt fixing part 51 is integrally formed with the retaining part body 53, for example. The bolt fixing part 51 has a through hole 61 through which the bolt B is inserted. It should be noted that, in Figure 2 , Figure 3 as well as Figure 4 In the diagram, the three mutually orthogonal directions of the fixing member 50 are shown: width direction X, depth direction Y, and height direction Z. Bolt B is inserted into the through hole 61 along the height direction Z. Additionally, the wire harness body 11 is positioned in the retaining part 52 with its length direction along the depth direction Y.

[0081] like Figure 2 and Figure 4 As shown, the bolt fixing part 51 has a side surface 51a facing the panel P in the assembled state when assembled to the vehicle V. One end of the through hole 61 in the height direction Z opens on the side surface 51a. That is, the through hole 61 has a bolt insertion port 62 on the side surface 51a for inserting the bolt B. It should be noted that the through hole 61 in this embodiment also opens on both sides in the depth direction Y.

[0082] A locking portion 63 is provided inside the through hole 61, which locks the bolt B inserted from the bolt insertion port 62 into the bolt fixing portion 51 in the axial direction. The locking portion 63 extends, for example, from a pair of inner wall surfaces 64 facing each other in the width direction X of the through hole 61. Multiple locking portions 63 are arranged, for example, in the height direction Z. The locking portion 63 is inclined, for example, towards the front side of the bolt B insertion direction as it moves inward from the pair of inner wall surfaces 64. The locking portion 63 locks with the thread of the bolt B in the axial direction at its own tip.

[0083] (Structure of the force-applying part 65)

[0084] The bolt fixing part 51 has a force-applying part 65 on its side 51a. The force-applying part 65 is located, for example, on both sides of the bolt insertion port 62 in the depth direction Y. Each force-applying part 65 has a pair of elastic plates 66 extending from the side 51a. The pair of elastic plates 66 are inclined in a manner that they move closer to each other as they move away from the side 51a. The tips 66a of the pair of elastic plates 66 face each other. That is, the positions of the tips 66a in the height direction Z are consistent with each other.

[0085] like Figure 2 As shown, viewed from the depth direction Y, the pair of elastic plates 66 are linearly symmetrical with respect to the central axis L of the bolt insertion port 62. It should be noted that the central axis L of the bolt insertion port 62 is along the height direction Z. Viewed from the depth direction Y, the distances from the central axis L to each root 66b are equal. Furthermore, viewed from the depth direction Y, the distances from the central axis L to each tip 66a are equal.

[0086] The function of this embodiment will be explained.

[0087] When assembling the fixing member 50 onto the bolt B, the bolt B is inserted into the through hole 61 of the bolt fixing part 51 along the height direction Z. As a result, each locking part 63 engages with the outer peripheral surface of the bolt B in the axial direction. Furthermore, each elastic piece 66 of each force-applying part 65 elastically contacts the panel P. That is, each elastic piece 66 contacts the panel P in a flexed state with its tip 66a flexing towards the side 51a. As a result, each elastic piece 66 applies a force to the panel P. This suppresses the wobbling of the fixing member 50.

[0088] The effects of this implementation method will be explained.

[0089] (1) The bolt fixing part 51 includes: a side surface 51a, facing the panel P; and a bolt insertion port 62, provided on the side surface 51a, into which a bolt B is inserted. Furthermore, the bolt fixing part 51 includes: a locking part 63, which locks the bolt B inserted into the bolt fixing part 51 from the bolt insertion port 62 in the axial direction; and a force-applying part 65, provided on the side surface 51a, in contact with the panel P. The force-applying part 65 has a pair of elastic pieces 66 extending from the side surface 51a. The pair of elastic pieces 66 are inclined such that they move closer to each other as they move away from the side surface 51a. Furthermore, the tips 66a of the pair of elastic pieces 66 face each other.

[0090] According to this structure, the tips 66a of the pair of elastic sheets 66 of the force-applying part 65 face each other. Therefore, for example, during the handling of the fixing member 50, or during the assembly of the wiring harness 10 including the fixing member 50 into the vehicle V, the hooking of the tips 66a of the elastic sheets 66 can be suppressed. Thus, damage to the elastic sheets 66 of the force-applying part 65 can be suppressed.

[0091] (2) The wire harness 10 includes: an outer member 30 that covers the outer periphery of the wire member 20; and a path limiting member 40 that is fitted onto the outer periphery of the outer member 30 and limits the path of the outer member 30. The path limiting member 40 has an insertion port 40X that opens in a direction orthogonal to the length direction of the path limiting member 40 and extends throughout the length direction of the path limiting member 40. According to this structure, in the wire harness 10 equipped with the path limiting member 40, damage to the force-applying portion 65 can be suppressed.

[0092] (3) The retaining part 52 retains the path limiting member 40 in such a way that it covers the entire circumference of the path limiting member 40. The retaining part 52 has a protrusion 59 that protrudes inward. Furthermore, the protrusion 59 is located inside the insertion port 40X. According to this structure, the protrusion 59 of the retaining part 52 can be used to restrict the path limiting member 40 from rotating relative to the retaining part 52.

[0093] This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined and implemented within the scope of technical inconsistency.

[0094] ·For example Figure 5 As shown, a connecting portion 67 can also be provided in the force-applying portion 65 to connect the top ends 66a of a pair of elastic sheets 66 to each other. Figure 5 In the structure shown, the thickness T2 of the connecting portion 67 is set to be thinner than the thickness T1 of each elastic sheet 66. The thickness T1 of the elastic sheet 66 is the thickness of the inclined portion of the elastic sheet 66. Furthermore, the thickness T1 of the elastic sheet 66 is the same, for example, in the inclined portion. In a pair of elastic sheets 66, for example, the thickness T1 is equal to each other. The connecting portion 67 is formed, for example, as a flat plate with the same thickness T2.

[0095] According to this structure, the rigidity of each elastic sheet 66 is improved by connecting the tips 66a of a pair of elastic sheets 66 to each other via a connecting portion 67. Furthermore, by connecting the tips 66a of a pair of elastic sheets 66 to each other via a connecting portion 67, the snagging of the tips 66a of each elastic sheet 66 can be suppressed. Therefore, damage to the elastic sheets 66 can be further suppressed. Additionally, by making the thickness T2 of the connecting portion 67 thinner than the thickness T1 of each elastic sheet 66, the flexibility of each elastic sheet 66 can be ensured, and the connecting portion 67 can be formed. It should be noted that when each elastic sheet 66 contacts and flexes with the panel P, the connecting portion 67 deforms. At this time, even if the connecting portion 67 is cut off, because the force applied from each elastic sheet 66 to the panel P is appropriately generated, there is no problem with the connecting portion 67 being cut off. It should be noted that... Figure 5 In the example shown, the thickness T2 of the connecting portion 67 is set to be thinner than the thickness T1 of each elastic sheet 66. However, it is not limited to this. The thicknesses T1 and T2 can also be equal, or the thickness T2 can be set to be thicker than the thickness T1.

[0096] • The force-applying part 65 in the above embodiment can also be changed to, for example... Figure 6 The force-applying portion 70 is shown. The force-applying portion 70 has a first connecting end 71, a second connecting end 72, and an elastic portion 73. The first connecting end 71 is connected to the side surface 51a of the bolt fixing portion 51. The second connecting end 72 is connected to the side surface 51a of the bolt fixing portion 51. The elastic portion 73 connects the first connecting end 71 and the second connecting end 72. The elastic portion 73 is, for example, formed as an arc shape that convexes towards the side protruding from the side surface 51a. Viewed in the depth direction Y, the force-applying portion 70 is linearly symmetrical with respect to the central axis L of the bolt insertion port 62. That is, viewed in the depth direction Y, the distance from the central axis L to the first connecting end 71 and the distance from the central axis L to the second connecting end 72 are equal. Furthermore, viewed in the depth direction Y, the top 74 of the elastic portion 73 overlaps with the central axis L. The top 74 is the central portion in the width direction X of the elastic portion 73 and is the portion of the elastic portion 73 located furthest from the side surface 51a. The elastic part 73 contacts the panel P at the portion including the top 74 and applies a force to the panel P.

[0097] According to the structure described above, the force-applying part 70 has a structure without a free end, that is, an end that is not connected to the side surface 51a. Therefore, for example, during the handling of the fixing member 50, or during the assembly of the wiring harness 10 including the fixing member 50 into the vehicle V, the snagging of the force-applying part 70 can be suppressed. As a result, damage to the force-applying part 70 can be suppressed. In addition, by forming the elastic part 73 into an arc shape that convexes towards the side surface 51a, the elastic part 73 can be used to apply appropriate force to the panel P.

[0098] The force-applying portions 65 in the above embodiment are respectively provided on both sides of the bolt insertion port 62 in the depth direction Y, but this is not limited to this; force-applying portions 65 may also be provided on both sides of the bolt insertion port 62 in the width direction X. Furthermore, the number of force-applying portions 65 is not limited to two; one or more may be provided. In addition, in the above embodiment, the pair of elastic plates 66 in the force-applying portion 65 are arranged in the depth direction Y, but this is not limited to this; the pair of elastic plates 66 may also be arranged in the width direction X.

[0099] • In the fixing member 50 of the above embodiment, the insertion port 55 of the retaining part body 53 is configured to face the panel P side, and the cover part 54 covering the insertion port 55 is configured to face the panel P, but it is not particularly limited to this. For example, it may be configured to have the insertion port 55 facing the side opposite to the bolt fixing part 51 in the width direction X.

[0100] • The structure of the path limiting member 40 in the above embodiment can be appropriately modified. For example, as long as the path limiting member 40 has an insertion port 40X and a structure that is fitted to the outer periphery of the outer member 30, other structures are not particularly limited.

[0101] Alternatively, the protrusion 45 of the above embodiment can be provided at a position on the circumference of the path limiting member 40 that is farther from the insertion port 40X than the top end of the first end 41.

[0102] Alternatively, the protrusion 46 of the above embodiment can be provided at a position on the circumference of the path limiting member 40 that is farther from the insertion port 40X than the top end of the second end 42.

[0103] Alternatively, the protrusions 45 and 46 of the above embodiments can be partially provided in the length direction of the path limiting member 40.

[0104] • At least one of the protrusions 45 and 46 in the above embodiments may also be omitted.

[0105] • In the path limiting member 40 of the above embodiment, the radial thickness of the connecting portion 43 changes in the circumferential direction.

[0106] The shape of the connecting portion 43 in the path limiting member 40 of the above embodiment is not limited to an arc shape; for example, it can be changed to an elliptical arc shape, a U-shaped shape, etc.

[0107] In the above embodiment, the path limiting member 40 is harder than the outer member 30, but it is not limited to this; it may also be of equal or less hardness to the outer member 30. That is, the path limiting member 40 only needs to function in a way that makes the wire harness body 11 less prone to bending than the wire harness body 11 without the path limiting member 40.

[0108] • In the retaining part 52, the protrusion 59 may not be provided on the cover part 54, but on the retaining part body 53 instead.

[0109] The fixing member 50 may also be a fixing member that holds the portion of the wire harness body 11 that does not have the path limiting member 40. Alternatively, the path limiting member 40 may be omitted in the wire harness 10 of the above embodiment.

[0110] • 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.

[0111] • 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.

[0112] • 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.

[0113] • 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.

[0114] 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.

[0115] • The braided component 25 in the wire component 20 of the above embodiment can also be omitted.

[0116] 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.

[0117] • 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.

[0118] 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.
