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. Existing technical documents Patent documents

[0003] Patent Document 1: Japanese Patent Application Publication No. 2006-46508 Summary of the Invention The problem that the invention aims to solve

[0004] Due to factors such as wiring harness path deviation, the position of the fixing member relative to the bolt on the vehicle side may sometimes shift in the facing direction of the pair of retaining tabs. In this case, the bolt becomes closer to either of the pair of retaining tabs, thus potentially making the retaining state of the retaining tabs and bolt unstable or unable to retain. As a result, it may be impossible to secure the fixing member to the bolt, or even if the fixing member can be secured to the bolt, the retaining may be unstable, causing the fixing member to detach from the bolt.

[0005] The purpose of this disclosure is to provide a wire harness that enables the fixing of a member relative to a bolt to be stable. Solution for solving the problem

[0006] The wire harness disclosed herein comprises: a wire member having a wire; and a fixing member for fixing the wire member to an installation object, the fixing member having: a bolt fixing portion for fixing to a bolt on the installation object; and a retaining portion for retaining the wire member, the bolt fixing portion having: a fixing portion body having an insertion hole through which the bolt is inserted; and a locking ring for fixing to the bolt by locking in the axial direction relative to the threaded portion of the bolt disposed inside the insertion hole, the insertion hole having a movement limiting portion that limits the relative movement of the locking ring in the axial direction of the bolt, the locking ring being configured to be movable in the orthogonal direction of the bolt inside the insertion hole.

[0008] Figure 1 This is a schematic structural diagram of the wiring harness according to an embodiment. Figure 2 This is a schematic cross-sectional view illustrating the wiring harness used in this manner. Figure 3 This is a schematic exploded perspective view showing the wiring harness in this manner.

[0009] [Description of embodiments of this disclosure] First, the implementation methods of this disclosure are listed and explained. The wire harness disclosed herein, [1] The device comprises: a wire member having a wire; and a fixing member for fixing the wire member to an installation object, the fixing member having: a bolt fixing part for fixing to a bolt having on the installation object; and a retaining part for retaining the wire member, the bolt fixing part having: a fixing part body having an insertion hole through which the bolt is inserted; and a locking ring for fixing to the bolt by locking in the axial direction relative to the threaded portion of the bolt disposed inside the insertion hole, the insertion hole having a movement limiting part for limiting the relative movement of the locking ring in the axial direction of the bolt, the locking ring being configured to be movable in the orthogonal direction of the bolt inside the insertion hole.

[0010] According to this structure, because the relative movement of the retaining ring fixed to the bolt in the axial direction of the bolt is restricted by the movement limiting part, the bolt can be maintained in the through hole. Furthermore, the retaining ring is configured to move within the through hole in the orthogonal direction of the bolt's axis. That is, relative movement of the bolt, retaining ring, and fixing member in the orthogonal direction of the axis is permitted. Therefore, even if, for example, due to a path deviation of the wiring harness, the position of the fixing member relative to the bolt shifts in the orthogonal direction of the bolt's axis, the fixing member can be stably fixed relative to the bolt.

[0011] [2] The locking ring is configured to be movable in both a first direction orthogonal to the axial direction of the bolt and a second direction orthogonal to both the axial direction of the bolt and the first direction, inside the insertion hole.

[0012] This structure allows for positional offsets of the bolt and the fixing member in the first and second directions, which are orthogonal to the bolt's axial direction. Therefore, it further stabilizes the fixing member relative to the bolt.

[0013] [3] The main body of the fixing part has a ring insertion hole, which is connected to the through hole, so that the locking ring can be inserted into the ring insertion hole. According to this structure, a locking ring can be inserted from the ring insertion hole into the through hole and fixed in the bolt within the through hole.

[0014] [4] The locking ring is C-shaped when viewed from the axial direction of the bolt. This structure makes the assembly of locking circumferential bolts easy. [5] The device comprises: an outer casing member that covers the outer periphery of the wire component; and a path limiting member that is installed on 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 a path limiting member.

[0015] [6] 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 inner circumference and is located inside the insertion port. According to this structure, the protrusion of the retaining portion can be used to limit the relative rotation of the path limiting member with respect to the retaining portion.

[0016] [Details of the embodiments of this disclosure] The following is a reference to the appendix. Figure 1 Specific 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.

[0017] It should be noted that the term "opposite" in this specification 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, the term "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 placed between the two parts.

[0018] (Overall structure of wire harness 10) Figure 1The 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.

[0019] 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.

[0020] 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 mounted at 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.

[0021] (Structure of electrical component 20) 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.

[0022] 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.

[0023] 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.

[0024] 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. 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.

[0025] 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.

[0026] (Structure of external component 30) 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.

[0027] 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.

[0028] (Structure of path restriction component 40) like Figure 2 and Figure 3As 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 restricts 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.

[0029] 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, the straight portion 11A of the path limiting member 40, which is straight in the path of the wire harness body 11, is mounted on the outer periphery of the outer component 30.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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. 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 mounted on the outer periphery of the outer member 30.

[0041] (Structure of fixed component 50) like Figure 2 As shown, the wiring harness 10 includes a fixing member 50, which is used to fix 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 the portion of the wire harness body 11 that is, for example, bound by the installation path restriction member 40.

[0042] 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.

[0043] 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.

[0044] (Structure of retaining part 52) 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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, for example, by protruding from the inner surface of the cover portion 54. One or more protrusions 59 are provided.

[0049] With the cover 54 in the closed position, the protrusion 59 is located inside the insertion port 40X of the path limiting member 40. Therefore, the path limiting member 40 can be restricted from rotating relative to the retaining portion 52 by the protrusion 59. 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.

[0050] (Structure of bolt fixing part 51) The bolt fixing part 51 includes a fixing part body 61 and a locking ring 71 assembled to the fixing part body 61.

[0051] The fixing part body 61 is integrally formed with the retaining part body 53, for example. The fixing part body 61 has a through hole 62 through which a 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 62 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.

[0052] like Figure 2 As shown, the fixing body 61 has a first side surface 61a facing the panel P in the installed state when mounted to the vehicle V. One end of the through hole 62 in the height direction Z is open on the first side surface 61a. That is, the through hole 62 has a bolt insertion port 63 on the first side surface 61a for inserting a bolt B. It should be noted that the through hole 62 in this embodiment also opens on both sides in the depth direction Y.

[0053] The fixing part body 61 has a second side 61b that intersects with the first side 61a. The second side 61b is, for example, orthogonal to the first side 61a. The second side 61b is the side opposite to the side where the retaining part 52 is provided in the width direction X.

[0054] like Figure 2 and Figure 4 As shown, the through hole 62 has a first inner wall surface 62a and a second inner wall surface 62b that are opposite to each other in the width direction X. The fixing part body 61 has an annular insertion hole 64 that communicates from the second side surface 61b to the first inner wall surface 62a. The annular insertion hole 64 opens in the second side surface 61b in a direction orthogonal to the height direction Z, for example, the width direction X. That is, the annular insertion hole 64 connects the inner side of the through hole 62 and the outer side of the fixing part body 61 along the width direction X.

[0055] The fixing part body 61 has a recess 65 on the second inner wall surface 62b of the insertion hole 62. A portion of the locking ring 71 is inserted into the recess 65. The recess 65 is located at the same position as the ring insertion hole 64 in the height direction Z.

[0056] (Structure of locking ring 71) The locking ring 71, viewed from the height direction Z, is, for example, C-shaped. That is, the locking ring 71 has a pair of ends 72, with a bolt assembly port 73 between the pair of ends 72. Additionally, the locking ring 71 is, for example, a flat plate in the height direction Z. The overall shape of the locking ring 71 is, for example, generally circular. The locking ring 71 is, for example, made of resin or metal.

[0057] When assembling the fixing component 50 and the bolt B, firstly, the bolt B is inserted from the bolt insertion port 63 into the through hole 62 along the height direction Z. Then, the retaining ring 71 is assembled into the bolt B within the insertion hole 62. The retaining ring 71 is inserted into the insertion hole 62 from the ring insertion hole 64 along the width direction X. At this time, the bolt B is inserted radially into the inner circumference of the retaining ring 71 from the bolt assembly opening 73. As the bolt B is inserted into the bolt assembly opening 73, a pair of ends 72 are expanded by the bolt B. Furthermore, when the bolt B is inserted into the inner circumference of the retaining ring 71, the retaining ring 71 elastically returns to its original shape. It should be noted that the inner diameter of the retaining ring 71 is set slightly smaller than the diameter D1 of the threaded portion Ba on the outer circumference of the bolt B. That is, the retaining ring 71 elastically clamps the bolt B.

[0058] Furthermore, the retaining ring 71 is locked in the axial direction relative to the threaded portion Ba on the outer circumferential surface of the bolt B. That is, the retaining ring 71 is hooked into the threaded portion Ba in the axial direction, thereby fixing the retaining ring 71 to the bolt B in a fixed position in the axial direction without movement.

[0059] With the locking ring 71 fixed to the bolt B, a portion of the locking ring 71 is located inside the ring insertion hole 64. Therefore, the locking ring 71 can abut against the inner surface of the ring insertion hole 64 in the height direction Z. Thus, the relative movement of the locking ring 71 in the height direction Z is restricted by the inner surface of the ring insertion hole 64.

[0060] Furthermore, with the locking ring 71 fixed to the bolt B, a portion of the locking ring 71 is located inside the recess 65. Therefore, the locking ring 71 can abut against the inner surface of the recess 65 in the height direction Z. Thus, the relative movement of the locking ring 71 in the height direction Z is restricted by the inner surface of the recess 65. It should be noted that in this embodiment, the relative movement of the locking ring 71 to both sides in the height direction Z is restricted by both the ring insertion hole 64 and the recess 65.

[0061] The locking ring 71 is configured to be able to move in a direction orthogonal to the axis of bolt B inside the through hole 62. like Figure 4 As shown, the dimensions L1 of the bolt insertion port 63 in the width direction X and L2 of the bolt insertion port 63 in the depth direction Y are both greater than the diameter D1 of the threaded portion Ba. Therefore, with the bolt B inserted into the bolt insertion port 63, the bolt B and the retaining ring 71 can move in the orthogonal direction of the axis.

[0062] In the width direction X, the distance L3 from the inner side surface 65a of the recess 65 to the opening end on the second side surface 61b of the ring insertion hole 64 is greater than the outer diameter D2 of the locking ring 71. Furthermore, the dimension L4 of the ring insertion hole 64 in the depth direction Y is greater than the outer diameter D2 of the locking ring 71. The dimension L5 of the recess 65 in the depth direction Y is also greater than the outer diameter D2 of the locking ring 71. It should be noted that the dimensions L4 of the ring insertion hole 64 and L5 of the recess 65 are, for example, set to be equal. With this dimensional setting, within the through hole 62 including the ring insertion hole 64 and the recess 65, a region is ensured where the locking ring 71, fixed to the bolt B, can move relative to the bolt B in the direction orthogonal to the bolt B's axis.

[0063] The effects of this implementation method will be explained. (1) The bolt fixing part 51 has a fixing part body 61, which has an insertion hole 62 through which the bolt B is inserted. Additionally, the bolt fixing part 51 has a retaining ring 71, which is fixed to the bolt B by locking in the axial direction relative to the threaded portion Ba of the bolt B disposed inside the insertion hole 62. The insertion hole 62 has a ring insertion hole 64 and a recess 65, which restrict the relative movement of the retaining ring 71 in the axial direction of the bolt B. Furthermore, the retaining ring 71 is configured such that it can move within the insertion hole 62 in the orthogonal direction of the bolt B's axis, namely the width direction X, the depth direction Y, and the direction in which those directions combine.

[0064] According to this structure, since the relative movement of the retaining ring 71 fixed to bolt B in the axial direction of bolt B is restricted by the ring insertion hole 64 and the recess 65, the bolt B can be maintained in the insertion hole 62. Furthermore, the retaining ring 71 is configured to move in the orthogonal direction of the bolt B's axis within the insertion hole 62. That is, relative movement of bolt B, retaining ring 71, and fixing member 50 in the orthogonal direction of the axis is permitted. Therefore, even if, for example, due to a path offset of the wiring harness 10, the position of the fixing member 50 relative to bolt B shifts in the orthogonal direction of bolt B, the fixing member 50 relative to bolt B can be stably secured.

[0065] (2) The locking ring 71 is configured to move within the through hole 62 in both the width direction X, which is orthogonal to the axial direction of bolt B, and the depth direction Y, which is orthogonal to both the axial direction and the width direction X of bolt B. This structure allows for positional displacement of bolt B and fixing member 50 in the first and second directions orthogonal to the axial direction of bolt B. Therefore, the fixing of fixing member 50 relative to bolt B can be further stabilized.

[0066] (3) The main body 61 of the fixing part has a ring insertion hole 64, which is connected to the through hole 62, so that the locking ring 71 can be inserted into the ring insertion hole 64. According to this structure, the locking ring 71 can be inserted from the ring insertion hole 64 into the through hole 62 and fixed in the through hole 62.

[0067] (4) The locking ring 71 is C-shaped when viewed from the axial direction of bolt B. This structure makes it easy to assemble the locking ring 71 towards the bolt B.

[0068] (5) 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 installed on 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, the fixing member 50 can be stably fixed relative to the bolt B.

[0069] (6) 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 path limiting member 40 can be restricted from rotating relative to the retaining part 52 by means of the protrusion 59 of the retaining part 52.

[0070] 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. • The shape of the locking ring 71 can be changed to, for example, an ellipse or a polygon.

[0071] The locking ring 71 in the above embodiment is in the shape of a flat plate, but it is not limited to this. For example, the cross-sectional shape of the locking ring 71 along its radial direction can be circular or elliptical.

[0072] • In the above embodiment, the recess 65 can abut against the locking ring 71 on both sides in the axial direction, but it is not limited to this. For example, the locking ring 71 can abut against the recess 65 only in the direction in which the bolt B disengages from the through hole 62.

[0073] The shape of the through hole 62 in which the locking ring 71 can move is not limited to the above embodiment. As long as the locking ring 71 can move in the direction orthogonal to the axis of the bolt B, it can be appropriately modified from the above embodiment.

[0074] • In the bolt fixing part 51 of the above embodiment, one ring insertion hole 64 is provided, but it is not limited to this. Multiple ring insertion holes 64 may be provided, for example, in a manner arranged in the height direction Z. • 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.

[0075] • 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 installed on the outer periphery of the outer component 30, other structures are not particularly limited.

[0076] Alternatively, the protrusion 45 of the above embodiment can be provided at a position in the circumferential direction of the path limiting member 40 that is further away from the insertion port 40X than the top end of the first end 41. Alternatively, the protrusion 46 of the above embodiment can be provided at a position in the circumferential direction of the path limiting member 40 that is further away from the insertion port 40X than the top end of the second end 42.

[0077] • Alternatively, the protrusions 45 and 46 of the above embodiments can be partially provided in the length direction of the path limiting member 40. • At least one of the protrusions 45 and 46 in the above embodiments may also be omitted.

[0078] • In the path limiting member 40 of the above embodiment, the radial thickness of the connecting portion 43 changes in the circumferential direction. 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.

[0079] In the above embodiment, the path limiting member 40 is more rigid than the outer member 30, but it is not limited to this; it may also be as rigid as or less than 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 installed.

[0080] • 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. 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.

[0081] • 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. • 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.

[0082] • 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. • 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.

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

[0084] • The braided component 25 in the wire component 20 of the above embodiment can also be omitted. 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.

[0085] • The configuration relationship between the inverter M1 and the high-voltage battery M2 in vehicle V is not limited to the above implementation method and can be appropriately modified according to the vehicle structure. 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.
