[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-53894 Summary of the Invention The problem that the invention aims to solve
[0004] In a configuration where a wiring harness has multiple path-limiting members along its length, there is a situation where the ends of adjacent path-limiting members along this length direction overlap each other. That is, among adjacent path-limiting members along the length direction of the wiring harness, one path-limiting member's outer periphery covers the end of another. Here, if, due to vehicle-side constraints, a clamping member is fitted to the overlapping portion of the path-limiting members, a problem arises where the wiring harness's radial shape increases at the clamping member's mounting location.
[0005] The purpose of this disclosure is to provide a wire harness that enables radial miniaturization of the assembly portion of a fixing component. Solution for solving the problem
[0006] The wire harness disclosed herein comprises: a wire harness body having wire members and an outer member covering the outer periphery of the wire members; a first path limiting member fitted to the outer periphery of the outer member to limit the path of the wire harness body; a second path limiting member fitted to the outer periphery of the outer member to limit the path of the wire harness body; and a fixing member for fixing the second path limiting member to an assembly object. The first path limiting member has an insertion port that opens in a direction orthogonal to the length direction of the first path limiting member and extends throughout the entire length direction of the first path limiting member. The second path limiting member has a covering portion that covers the outer periphery of the end of the first path limiting member in the length direction. The covering portion has a first connecting portion that is partially provided in the circumferential direction of the wire harness body. The fixing member comprises: a fixing portion that is fixed to the assembly object; and a second connecting portion that is connected to the first connecting portion. Invention Effects

[0009] [Description of embodiments of this disclosure] First, embodiments of the present disclosure will be described and explained in parallel. The wire harness disclosed herein has: [1] A wire harness body having a wire member and an outer component covering the outer periphery of the wire member; a first path limiting member fitted to the outer periphery of the outer component to limit the path of the wire harness body; a second path limiting member fitted to the outer periphery of the outer component to limit the path of the wire harness body; and a fixing member fixing the second path limiting member to an assembly object, the first path limiting member having an insertion port that opens in a direction orthogonal to the length direction of the first path limiting member and extends throughout the entire length direction of the first path limiting member, the second path limiting member having a covering portion that covers the outer periphery of the end of the first path limiting member in the length direction, the covering portion having a first connecting portion that is partially provided in the circumferential direction of the wire harness body, the fixing member having a fixing portion that is fixed to the assembly object; and a second connecting portion that is connected to the first connecting portion.
[0010] According to this structure, the second connecting portion of the fixing member is connected to the first connecting portion, which is partially provided circumferentially on the covering portion of the second path limiting member. Therefore, the second connecting portion does not need to be formed to cover the entire circumference of the covering portion that overlaps with the first path limiting member radially. Therefore, it is possible to achieve radial miniaturization of the assembly part of the fixing member.
[0011] [2] The second path limiting member includes: a main body portion that limits the path of the wire harness body; a receiving portion disposed at the end of the main body portion in the length direction of the wire harness body; and a cover portion that, together with the receiving portion, covers the entire circumference of the end of the first path limiting member in the length direction, the receiving portion and the cover portion constituting the covering portion. According to this structure, a covering portion that covers the outer circumference of the end of the first path limiting member in the length direction can be formed by the receiving portion and the cover portion.
[0012] [3] The first connecting part has a first receiving part side connecting part disposed on the receiving part and a first cover side connecting part disposed on the cover part, and the second connecting part has a second receiving part side connecting part connected to the first receiving part side connecting part and a second cover side connecting part connected to the first cover side connecting part.
[0013] According to this structure, the receiving part and the cover part are connected to each other via the second receiving part side connecting part and the second cover part side connecting part. That is, by forming a state in which the fixing member is assembled on the covering part, it is possible to prevent the cover part from detaching from the receiving part.
[0014] [4] The covering part has a hinge part that connects one circumferential end of the receiving part to one circumferential end of the cover part. The cover part can rotate between an open position and a closed position covering the main body of the wire harness with the hinge part as the rotation axis. The first receiving part side connecting part is provided at one circumferential end of the receiving part, and the first cover side connecting part is provided at one circumferential end of the cover part.
[0015] According to this structure, by assembling the fixing member to the covering part, the cover in the closed position is not easily rotated in the opening direction. That is, the cover can be easily kept in the closed position by the fixing member assembled to the covering part.
[0016] [5] One of the first connecting portion and the second connecting portion is a recess, and the other of the first connecting portion and the second connecting portion is a convex portion that fits into the recess. According to this structure, the first connecting part and the second connecting part can be connected with a simple configuration.
[0017] [6] The second connecting part can be fitted to the first connecting part by sliding relative to the first connecting part along the length direction of the second path limiting member. According to this structure, the second connecting part can be assembled to the first connecting part by sliding the second connecting part along the length direction of the second path limiting member. Therefore, the fixing member can be easily assembled to the covering part of the second path limiting member.
[0018] [7] The first connecting part has a movement limiting part that limits the movement of the second connecting part along the length direction of the second path limiting member. According to this structure, the second connecting part can be prevented from detaching from the first connecting part by means of the movement restriction part.
[0019] [8] The first path limiting member restricts the path of the straight part, which is the straight part of the path of the wire harness body, and the second path limiting member restricts the path of the curved part, which is the bent part of the path of the wire harness body.
[0020] According to this structure, the path of the straight portion is restricted by the first path restricting member, and the path of the curved portion is restricted by the second path restricting member. Thus, it is possible to continuously prevent the paths of both the straight and curved portions of the wire harness body from deviating from their desired paths.
[0021] [Detailed Description of Embodiments of this Disclosure] The following description, in conjunction with the accompanying drawings, will illustrate specific examples of the wiring harness disclosed herein. In the drawings, for ease of explanation, some components may be shown exaggeratedly or simplified. Furthermore, the dimensional proportions of the various parts may differ in each drawing. Additionally, the term "orthogonal" in this specification includes not only strictly orthogonal cases but also approximately orthogonal cases within the scope of the functions and effects achieved in this embodiment.
[0022] Furthermore, in this specification, "opposite" refers to a position where surfaces or components are facing each other, including not only completely facing each other but also partially facing each other. Additionally, "opposite" in this specification refers to both the case where a component separately provided for the two parts is sandwiched between the two parts and the case where no component is sandwiched between the two parts.
[0023] Furthermore, as used in this specification, the term "ring-shaped" refers to any structure forming a ring, a continuous shape without ends, or a typical ring-shaped structure with gaps, such as a C-shape. Additionally, the shape of "ring-shaped" includes, but is not limited to, circles, ellipses, and polygons with sharp or rounded corners.
[0024] (Overall structure of wire harness 10) Figure 1 The wiring harness 10 shown is, for example, mounted on a vehicle V such as a hybrid vehicle / electric vehicle. The wiring harness 10 electrically connects two or more on-board devices to each other. On-board devices are electrical machines mounted on the vehicle V. The wiring harness 10, for example, electrically connects an inverter M1 located at the front of the vehicle V and a high-voltage battery M2 located further rear of the vehicle V than the inverter M1. The wiring harness 10 is, for example, formed as a long strip extending along the longitudinal direction of the vehicle V. The wiring harness 10 is routed inside the vehicle V, for example, with its middle portion passing outside the vehicle exterior, such as the floor, in the longitudinal direction.
[0025] Inverter M1 is connected, for example, to a wheel drive motor (not shown) that serves as the power source for the vehicle. Inverter M1 generates alternating current from direct current (DC) from a high-voltage battery M2 and supplies this AC current to the motor. The high-voltage battery M2 is, for example, a battery capable of supplying a voltage of several hundred volts.
[0026] 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.
[0027] like Figure 2 As shown, the wiring harness 10 has a first path limiting member 40 mounted on the outer periphery of the outer component 30, and a second path limiting member 50 mounted on the outer periphery of the outer component 30. The first path limiting member 40 and the second path limiting member 50 limit the wiring path of the wiring harness body 11. Additionally, the wiring harness 10 includes a fixing member 60 for fixing the second path limiting member 50 to the vehicle V. Furthermore, in... Figure 1 The illustrations of the first path limiting member 40, the second path limiting member 50, and the fixing member 60 are omitted.
[0028] (Composition of wire component 20) like Figure 3 as well as Figure 4 As shown, the wire component 20 may be one or more wires. In this embodiment, it has two wires 21 and a braided component 25 that surrounds the outer circumference of the multiple wires 21.
[0029] Each wire 21 is a sheathed wire, which includes a conductive core wire 22 and an insulating sheath 23 that surrounds and insulates the core wire 22. Each wire 21 is, for example, a high-voltage wire capable of handling high voltage / high current. Each wire 21 can be, for example, an unshielded wire without electromagnetic shielding or a shielded wire with electromagnetic shielding. In this embodiment, each wire 21 is an unshielded wire.
[0030] As the core wire 22, for example, stranded wire formed by twisting together multiple metal wires or a single-core wire formed by a single conductor can be used. As a single-core wire, for example, a cylindrical conductor formed by a single metal rod with a solid internal structure or a cylindrical conductor with a hollow internal structure can be used. As the core wire 22, stranded wire, cylindrical conductor / cylindrical conductor can be used in combination. As the material of the core wire 22, for example, copper-based or aluminum-based metal materials can be used.
[0031] The insulating sheath 23, for example, covers the entire circumference of the outer periphery of the core wire 22. The insulating sheath 23, for example, is made of an insulating resin material. The cross-sectional shape of each wire 21 obtained by cutting it with a plane orthogonal to its length direction can be any shape. For example, the cross-sectional shape of each wire 21 can be circular, semi-circular, polygonal, square, flat, etc. In this embodiment, the cross-sectional shape of each wire 21 is circular.
[0032] The braided member 25 is, for example, generally cylindrical, surrounding the outer circumference of the plurality of wires 21. As the braided member 25, for example, a braided wire made of multiple metal wires or a braided wire made by combining metal wires and resin wires can be used. As the material of the metal wires, for example, copper-based / aluminum-based metal materials can be used. Although not shown in the figure, connectors C1 and C2 (see [reference]) are used at both ends of the braided member 25 along its length. Figure 1 Grounding connection, etc.
[0033] (Composition of external component 30) The outer casing 30 is cylindrical, surrounding the outer periphery of the wire component 20 throughout its entire circumference. In this embodiment, the outer casing 30 is formed in a cylindrical shape. For example, the outer casing 30 has a continuous circumferential wall formed throughout its entire circumference. For example, the outer casing 30 seals the interior of the outer casing 30 throughout its entire circumference. For example, the outer casing 30 has the function of protecting the wire component 20 from impacts by flying objects / water droplets.
[0034] The outer component 30 is flexible, for example, and can be easily bent. Examples of flexible outer components 30 include, for example, resin-made corrugated tubes / rubber-made waterproof caps. In this embodiment, the outer component 30 is a resin corrugated tube, which has a corrugated shape with large-diameter portions and small-diameter portions repeatedly arranged along the length of the outer component 30. That is, the outer component 30 of this embodiment has a corrugated structure in which large-diameter portions 31 and small-diameter portions 32 with diameters smaller than the large-diameter portions 31 are alternately and continuously provided along the length of the outer component 30. The large-diameter portions 31 and small-diameter portions 32 are each, for example, annular, encircling the circumference of the outer component 30. As the material for the outer component 30, synthetic resins such as polyolefins, polyamides, polyesters, and ABS resins can be used. Furthermore, in Figure 2 In order to simplify the accompanying drawings, the outer component 30 is shown in a simplified manner.
[0035] (The composition of the first path limiting member 40 and the second path limiting member 50) like Figure 2 as well as Figure 3As shown, the first path limiting member 40 and the second path limiting member 50 each hold the outer member 30. The first path limiting member 40 and the second path limiting member 50 are, for example, more rigid than the outer member 30. The first path limiting member 40 and the second path limiting member 50 each have a stiffness that makes them less prone to bending in a direction orthogonal to the length direction of the wire harness body 11 than the outer member 30. Thus, the first path limiting member 40 and the second path limiting member 50 each restrict the path of the wire harness body 11. For example, the first path limiting member 40 and the second path limiting member 50 assist the outer member 30 in a way that prevents the wire harness body 11 from bending due to its own weight and thus detaching from the desired path.
[0036] like Figure 2 As shown, a first path limiting member 40 is partially provided along the length of the wire harness body 11. The first path limiting member 40, for example, has a straight portion 11A, which is a straight section in the path of the wire harness body 11, fitted to the outer periphery of the outer component 30. The first path limiting member 40 restricts the path of the wire harness body 11 at the straight portion 11A. Here, the straight portion 11A is the portion of the wire harness body 11 that extends in a straight line in one direction. Furthermore, the first path limiting member 40 may be provided singly or in multiples depending on the path of the wire harness body 11.
[0037] The second path limiting member 50 is partially provided along the length direction of the wire harness body 11. The second path limiting member 50, for example, is fitted to the outer periphery of the outer member 30 as a bent portion 11B in the path of the wire harness body 11. The second path limiting member 50 restricts the path of the wire harness body 11 at the bent portion 11B. Here, the bent portion 11B is the portion of the path of the wire harness body 11 that is bent away from a straight line. Furthermore, the second path limiting member 50 may be provided singly or in multiples depending on the path of the wire harness body 11.
[0038] (The structure of the first path limiting component 40) like Figure 2 as well as Figure 4 As shown, the first path limiting member 40 covers a portion of the circumferential periphery of the outer component 30. The first path limiting member 40 is a shape that partially covers the circumferential periphery of the outer component 30. The cross-sectional shape of the first path limiting member 40 is generally C-shaped. For example, the first path limiting member 40 covers an area larger than half the circumference of the outer component 30. That is, the first path limiting member 40 covers an area larger than half the entire circumference of the outer component 30.
[0039] like Figure 2As shown, the first path limiting member 40 extends along the length direction of the outer member 30 in the straight portion 11A. The first path limiting member 40 is formed, for example, into a shape that extends in a straight line in one direction. The cross-sectional shape of the first path limiting member 40 is, for example, the same throughout the entire length direction of the first path limiting member 40.
[0040] The first path limiting member 40 is made of, for example, metal or resin. In this embodiment, the first path limiting member 40 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyoxymethylene can be used as the material for the first path limiting member 40. The first path limiting member 40 can be manufactured, for example, by known manufacturing methods such as extrusion molding / injection molding. In this embodiment, the first path limiting member 40 is an extruded article manufactured by extrusion molding. Therefore, by using an extrusion molding machine that extrudes the raw material of the first path limiting member 40 along its length direction, the first path limiting member 40 can be easily manufactured. Furthermore, multiple first path limiting members 40 with different dimensions in the length direction can be manufactured using a single extrusion molding machine. For example, by cutting the base material of the first path limiting member 40 formed by a single extrusion molding machine to any length using a cutting machine, multiple first path limiting members 40 with different dimensions in the length direction can be manufactured.
[0041] like Figure 3 as well as Figure 4 As shown, the first path limiting member 40 has an insertion port 40X that opens in a direction orthogonal to the length direction of the first path limiting member 40. The insertion port 40X extends throughout the entire length direction of the first path limiting member 40. The first path limiting member 40 has a first end 41 and a second end 42, which are the two circumferential ends of the first path limiting member 40 and form the insertion port 40X. The first path limiting member 40 has a connecting portion 43 that connects the first end 41 and the second end 42. In other words, the first path limiting member 40 has: a connecting portion 43 formed to partially cover the circumferential direction of the outer member 30; a first end 41 and a second end 42, which are provided at the two ends of the connecting portion 43; and an insertion port 40X formed by the first end 41 and the second end 42.
[0042] The connecting portion 43 constitutes a major part of the first path limiting member 40. The radial thickness of the connecting portion 43 is the same in the circumferential direction of the first path limiting member 40, for example. The cross-sectional shape of the connecting portion 43 is formed, for example, along the outer surface of the outer member 30. The cross-sectional shapes of the first end 41, the second end 42, and the connecting portion 43 are formed, for example, in an arc shape.
[0043] The first end 41 and the second end 42 are disposed on opposite sides of the first path limiting member 40 in the circumferential direction. The first end 41 and the second end 42 are separated from each other in the circumferential direction of the first path limiting member 40 by an insertion opening 40X. In other words, in the circumferential direction of the first path limiting member 40, the gap between the first end 41 and the second end 42 constitutes the insertion opening 40X. Thus, the first path limiting member 40 is formed in a C-shape with the insertion opening 40X partially present in the circumferential direction of the first path limiting member 40.
[0044] The top ends of the first end 41 and the second end 42 are formed in a curved shape. In this embodiment, the top ends of the first end 41 and the second end 42 are formed in an arc shape.
[0045] 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. Each protrusion 45, 46 extends along the length direction of the first path limiting member 40. For example, each protrusion 45, 46 extends along the entire length direction of the first path limiting member 40.
[0046] Each protrusion 45, 46 presses against the outer component 30 from the outside. The outer component 30 is elastically held by the protrusions 45, 46 and the connecting part 43. As a result, the connection between the first path limiting member 40 and the outer component 30 becomes secure.
[0047] like Figure 4 As shown, the opening width of the insertion port 40X, that is, the shortest distance between the first end 41 and the second end 42, is smaller than the outer diameter of the outer component 30. The opening width of the insertion port 40X increases due to the elastic deformation of the first path limiting member 40. For example, the opening width of the insertion port 40X increases because the outer member 30 is inserted into the insertion port 40X from a direction orthogonal to the length direction of the first path limiting member 40. If the outer member 30 is inserted inside the first path limiting member 40, the first path limiting member 40 elastically returns to its original shape. As a result, the opening width of the insertion port 40X is smaller than the outer diameter of the outer member 30, and therefore, the first path limiting member 40 is fitted to the outer periphery of the outer member 30.
[0048] (The composition of the second path restriction component 50) like Figure 2 As shown, the second path limiting member 50 is fitted to the outer periphery of the outer member 30 at the bend 11B. The second path limiting member 50 extends along the length direction of the outer member 30 at the bend 11B. The second path limiting member 50 is bent, for example, along the shape of the bend 11B.
[0049] The second path limiting member 50 is made of, for example, metal or resin. In this embodiment, the second path limiting member 50 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyoxymethylene can be used as the material for the second path limiting member 50. The second path limiting member 50 can be manufactured, for example, by known manufacturing methods such as injection molding.
[0050] The second path limiting member 50 has a main body 51 and a covering part 52 that covers the end 40a of the first path limiting member 40 in the longitudinal direction. The main body 51 is, for example, formed as an elongated strip extending along the length direction of the outer member 30 at the bend 11B. The main body 51 extends along the path of the bend 11B, for example. That is, the main body 51 has a bent shape that bends along the shape of the bend 11B. The main body 51 partially covers the circumferential portion of the outer member 30. For example, the main body 51 covers approximately half of the outer periphery of the outer member 30. For example, the main body 51 covers approximately 180° of the outer periphery of the outer member 30. The main body 51 is, for example, generally semi-cylindrical.
[0051] The covering portion 52 is provided at one end of the main body portion 51 in the longitudinal direction. It has a receiving portion 53 integrally formed at one end of the main body portion 51 in the longitudinal direction, and a cover portion 54 covering the receiving portion 53.
[0052] The receiving portion 53 partially covers the circumferential portion of the first path limiting member 40. The receiving portion 53 also partially covers the circumferential portion of the end 40a of the first path limiting member 40 along its length. The receiving portion 53 is shaped to partially cover the circumferential portion of the first path limiting member 40. The cross-sectional shape of the receiving portion 53 is generally semi-cylindrical. For example, the receiving portion 53 is a semi-cylindrical shape with a diameter larger than that of the main body portion 51. For example, the receiving portion 53 covers half of the outer periphery of the first path limiting member 40.
[0053] The cover portion 54 and the receiving portion 53 together cover the entire circumference of the end portion 40a of the first path limiting member 40. Specifically, the cover portion 54 and the receiving portion 53 together cover the entire circumference of the end portion 40a of the first path limiting member 40 along its outer periphery. In this embodiment, the cover portion 54 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 that protrudes from the insertion opening 40X.
[0054] The cover portion 54 has a semi-cylindrical cross-sectional shape. The cover portion 54 has a semi-cylindrical shape with the same diameter as the receiving portion 53. The cover portion 54 covers the portion of the outer periphery of the first path limiting member 40 that is not covered by the receiving portion 53, that is, half of the outer periphery of the first path limiting member 40.
[0055] The cover portion 54 is integrally formed with the receiving portion 53, for example. Specifically, the covering portion 52 has, for example, a hinge portion 55 that connects the receiving portion 53 to the cover portion 54. The hinge portion 55 connects one circumferential end 53a of the receiving portion 53 to one circumferential end 54a of the cover portion 54. One or more (two in this embodiment) locking portions 56 are provided at the other circumferential end 53b of the receiving portion 53. One or more (two in this embodiment) claw portions 57 are provided at the other circumferential end 54b of the cover portion 54.
[0056] The cover 54 can rotate around the hinge 55. Figure 3 The opening position shown is the same as Figure 2 , Figure 4 Rotate between the closed positions shown. For example... Figure 4 As shown, with the cover 54 in the closed position, the claw 57 hooks onto the locking part 56. Thus, the cover 54 is held in the closed position.
[0057] Thus, the receiving portion 53 and the cover portion 54 are connected to each other. With the receiving portion 53 and the cover portion 54 connected, the covering portion 52 is annular, enclosing the outer periphery of the outer component 30 and the end portion 40a of the first path limiting member 40. The covering portion 52 has a first connecting portion 58 for connecting the fixing member 60. The first connecting portion 58 is partially provided circumferentially in the covering portion 52.
[0058] In addition, such as Figure 2 As shown, the wire harness 10, for example, has a first sliding limiting member 91, which limits the sliding movement of the first path limiting member 40 relative to the outer component 30 in the longitudinal direction. Additionally, the wire harness 10, for example, has a second sliding limiting member 92, which limits the sliding movement of the second path limiting member 50 relative to the outer component 30 in the longitudinal direction. The first sliding limiting member 91 and the second sliding limiting member 92 can be, for example, made of resin or metal, such as cable ties, rivet rings / tape. In this embodiment, the first sliding limiting member 91 and the second sliding limiting member 92 are tape. The first sliding limiting member 91 is wound across the end of the first path limiting member 40 that is not connected to the second path limiting member 50 and onto the outer component 30. The second sliding limiting member 92 is wound across the end of the second path limiting member 50 that is not connected to the first path limiting member 40 and onto the outer component 30.
[0059] (Composition of fixed component 60) like Figure 4 As shown, the fixing member 60 fixes the second path limiting member 50 to the panel P of the floor portion constituting the vehicle V. The fixing member 60 is made of metal or resin, for example. In this embodiment, the fixing member 60 is made of resin. As a material for the fixing member 60, synthetic resins such as polypropylene, polyamide, and polyoxymethylene can be used. The fixing member 60 can be manufactured, for example, by a known manufacturing method such as injection molding.
[0060] like Figure 3 as well as Figure 4 As shown, the fixing member 60 has a fixing part 61 fixed to the panel P and a second connecting part 62 connected to the first connecting part 58 of the second path limiting member 50. As an example, the fixing part 61 has a structure for fixing to a bolt B extending from the panel P. The fixing part 61 has a through hole 63 for the bolt B to be inserted. Additionally, in Figure 4 In the diagram, the three mutually orthogonal directions of the fixing member 60 are shown: the width direction X, the depth direction Y, and the height direction Z. Bolt B is inserted into the through hole 63 along the height direction Z.
[0061] The fixing part 61 has a first side surface 61a facing the panel P in the assembled state when assembled with the vehicle V. In the first side surface 61a, one end of the through hole 63 is open in the height direction Z. That is, the through hole 63 has a bolt insertion port 64 on the first side surface 61a for inserting a bolt B. Furthermore, in this embodiment, the through hole 63 is open on both sides in the depth direction Y.
[0062] like Figure 4 As shown, a locking portion 65 is provided inside the insertion hole 63, which engages axially with the bolt B inserted from the bolt insertion port 64 into the fixing portion 61. The locking portions 65 extend, for example, from a pair of opposing inner wall surfaces in the insertion hole 63 along the width direction X. Multiple locking portions 65 are arranged, for example, along the height direction Z. The locking portions 65, for example, are inclined forward of the bolt B insertion direction as they extend inward from the pair of inner wall surfaces. The locking portion 65 engages axially with the thread of the bolt B at its tip.
[0063] The fixing part 61 has an elastic piece 66 on the first side 61a. The elastic piece 66 is provided on both sides in the depth direction Y relative to the through hole 63, for example. The elastic piece 66 is in elastic contact with the panel P in the assembled state when assembled in the vehicle V. That is, the elastic piece 66 applies elastic force to the panel P. As a result, the wobbling of the fixing member 60 can be suppressed.
[0064] (The structure of the first connecting part 58 and the second connecting part 62) The first connecting portion 58 of the covering portion 52 has a first receiving portion-side connecting portion 71 provided at one circumferential end 53a of the receiving portion 53, and a first cover-side connecting portion 72 provided at one circumferential end 54a of the cover portion 54. The second connecting portion 62 of the fixing member 60 has a second receiving portion-side connecting portion 81 connected to the first receiving portion-side connecting portion 71, and a second cover-side connecting portion 82 connected to the first cover-side connecting portion 72. The second receiving portion-side connecting portion 81 and the second cover-side connecting portion 82 each have, for example, a protrusion protruding from a second side surface 61b in the width direction X of the fixing portion 61. In addition, in this embodiment, the second receiving portion-side connecting portion 81 and the second cover-side connecting portion 82 are integrally formed with the fixing portion 61. The first receiving side connecting portion 71 and the first cover side connecting portion 72 are each recesses for the second receiving side connecting portion 81 and the second cover side connecting portion 82 to fit into.
[0065] The first receiving portion side connecting portion 71 is partially provided in the circumferential direction of the receiving portion 53. The first cover portion side connecting portion 72 is partially provided in the circumferential direction of the cover portion 54. The cross-sectional shape of each of the first receiving-side connecting portion 71 and the first cover-side connecting portion 72, orthogonal to the length direction of the second path limiting member 50, is approximately T-shaped. Specifically, each of the first receiving-side connecting portion 71 and the first cover-side connecting portion 72 has a first receiving portion 73 and a pair of second receiving portions 74 and 75. The first receiving portion 73 extends radially from the outer periphery of the covering portion 52 into the wall thickness of the covering portion 52. The pair of second receiving portions 74 and 75 extend from the first receiving portion 73 in opposite directions along the circumferential direction of the covering portion 52. The second receiving portion 75 extends from the first receiving portion 73 toward the hinge portion 55, and the second receiving portion 74 extends in the opposite direction to the second receiving portion 75. The circumferential lengths of the pair of second receiving portions 74 and 75 are formed such that, for example, the second receiving portion 74 is longer than the second receiving portion 75.
[0066] The cross-sectional shapes of the second receiving-side connecting portion 81 and the second cover-side connecting portion 82, which are orthogonal to the length direction of the second path limiting member 50, are approximately T-shaped, similar to the cross-sectional shapes of the first receiving-side connecting portion 71 and the first cover-side connecting portion 72. Specifically, each of the second receiving-side connecting portion 81 and the second cover-side connecting portion 82 has a base 83 extending from the second side surface 61b along the width direction X, and a pair of extensions 84 and 85 extending in two directions from the top of the base 83. The base 83 is fitted into the first receiving portion 73. The pair of extensions 84 and 85 are respectively fitted into a pair of second receiving portions 74 and 75. The pair of extensions 84 and 85 extend from the top of the base 83 in opposite directions along the circumferential direction of the covering portion 52. The circumferential lengths of the pair of extensions 84 and 85 are formed such that, for example, extension 84 is longer than extension 85. The extension 84 is fitted into the second storage section 74. The extension 85 is fitted into the second storage section 75.
[0067] like Figure 2 as well as Figure 5 As shown, the first connecting portion 58 extends along the length of the second path limiting member 50 to one end of the covering portion 52. That is, the first receiving portion-side connecting portion 71 extends along the length of the second path limiting member 50 to one end 53c of the receiving portion 53. Thus, the first receiving portion-side connecting portion 71 opens at the end 53c of the receiving portion 53 towards the length of the second path limiting member 50. Therefore, the second receiving portion-side connecting portion 81 can be fitted to the first receiving portion-side connecting portion 71 by sliding along the length of the second path limiting member 50 from the opening at the end 53c side.
[0068] Furthermore, the first cover-side connecting portion 72 extends along the length of the second path limiting member 50 to the end 54c on one side of the cover portion 54. Thus, the first cover-side connecting portion 72 opens at the end 54c of the cover portion 54 into the length of the second path limiting member 50. Therefore, the second cover-side connecting portion 82 can be fitted to the first cover-side connecting portion 72 by sliding along the length of the second path limiting member 50 from the opening at the end 54c side.
[0069] like Figure 5 As shown, the first receiving-side connecting portion 71 has a first movement limiting portion 76, which limits the movement of the second receiving-side connecting portion 81 along the length direction of the second path limiting member 50. The first movement limiting portion 76 is the bottom wall of the first receiving-side connecting portion 71 extending along the length direction of the second path limiting member 50. When the second receiving-side connecting portion 81 is fitted into the first receiving-side connecting portion 71, the first movement limiting portion 76 is opposite to the second receiving-side connecting portion 81 in the length direction of the second path limiting member 50. Thus, the first movement limiting portion 76 limits the movement of the second receiving-side connecting portion 81 within the first receiving-side connecting portion 71 along the length direction of the second path limiting member 50. Furthermore, the first movement limiting portion 76 is provided in the same manner as the first cover-side connecting portion 72, and functions similarly to the second cover-side connecting portion 82.
[0070] Furthermore, the first receiving-side connecting portion 71 has a second movement limiting portion 77, which restricts the movement of the second receiving-side connecting portion 81 along the length direction of the second path limiting member 50. The second movement limiting portion 77 is, for example, a protrusion extending from the inner surface of the second receiving portion 74 in the first receiving-side connecting portion 71. When the second receiving-side connecting portion 81 is fitted to the first receiving-side connecting portion 71 by sliding movement, the second receiving-side connecting portion 81 slides past the second movement limiting portion 77. The second movement limiting portion 77 restricts the movement of the second receiving-side connecting portion 81, which is fitted into the first receiving-side connecting portion 71, along the length direction of the second path limiting member 50. Therefore, the movement of the second receiving part side connecting part 81 in the length direction on one side is restricted by the first movement restriction part 76, and the movement of the second receiving part side connecting part 81 in the length direction on the other side is restricted by the second movement restriction part 77.
[0071] The effects of this implementation method will be explained. (1) The second connecting portion 62 of the fixing member 60 is connected to the first connecting portion 58, which is partially provided circumferentially on the covering portion 52 of the second path limiting member 50. Therefore, the second connecting portion 62 does not need to be formed to cover the entire circumference of the covering portion 52 that overlaps with the first path limiting member 40 radially. Therefore, it is possible to achieve radial miniaturization of the assembly part of the fixing member 60.
[0072] (2) The second path limiting member 50 includes: a main body portion 51 that limits the path of the wire harness body 11; and a receiving portion 53 disposed at the end of the main body portion 51 in the length direction of the wire harness body 11. Furthermore, the second path limiting member 50 includes a cover portion 54, which, together with the receiving portion 53, covers the entire circumference of the end portion 40a of the first path limiting member 40 in the length direction. The receiving portion 53 and the cover portion 54 constitute a covering portion 52. According to this structure, the receiving portion 53 and the cover portion 54 can form a covering portion 52 that covers the outer circumference of the end portion 40a of the first path limiting member 40.
[0073] (3) The first connecting portion 58 has a first receiving portion-side connecting portion 71 provided on the receiving portion 53 and a first cover-side connecting portion 72 provided on the cover portion 54. Furthermore, the second connecting portion 62 has a second receiving portion-side connecting portion 81 connected to the first receiving portion-side connecting portion 71 and a second cover-side connecting portion 82 connected to the first cover-side connecting portion 72. According to this structure, with the fixing member 60 assembled on the covering portion 52, the receiving portion 53 and the cover portion 54 are connected to each other via the second receiving portion-side connecting portion 81 and the second cover-side connecting portion 82. That is, by assembling the fixing member 60 on the covering portion 52, it is possible to prevent the cover portion 54 from detaching from the receiving portion 53.
[0074] (4) The covering portion 52 has a hinge portion 55, which connects one circumferential end 53a of the receiving portion 53 to one circumferential end 54a of the cover portion 54. The cover portion 54 is configured to rotate about the hinge portion 55 as a rotation axis between an open position and a closed position covering the main body 11 of the wire harness. A first receiving portion side connecting portion 71 is provided at one circumferential end 53a of the receiving portion 53. Furthermore, a first cover side connecting portion 72 is provided at one circumferential end 54a of the cover portion 54. According to this structure, by configuring the fixing member 60 to be assembled to the covering portion 52, the cover portion 54 in the closed position is not easily rotated in the opening direction. That is, the fixing member 60 assembled to the covering portion 52 easily maintains the cover portion 54 in the closed position.
[0075] Furthermore, a locking part 56 and a claw part 57 are respectively provided at the other circumferential end 53b of the receiving part 53 and the other circumferential end 54b of the cover part 54 to lock the cover part 54 in a closed state and to engage with each other. The locking part 56 and the claw part 57 tend to be larger than the hinge part 55 in the radial direction of the covering part 52. Therefore, by forming a configuration in which the fixing member 60 is fixed to the hinge part 55 side relative to the covering part 52, it is more advantageous to miniaturize the assembly part of the fixing member 60 in the radial direction.
[0076] (5) The first connecting part 58 is a recessed part, and the second connecting part 62 is a protruding part that fits into the first connecting part 58. According to this structure, the first connecting part 58 and the second connecting part 62 can be connected with a simple configuration.
[0077] (6) The second connecting portion 62 can be fitted to the first connecting portion 58 by sliding along the length direction of the second path limiting member 50. According to this structure, the second connecting portion 62 can be fitted to the first connecting portion 58 by sliding along the length direction of the second path limiting member 50. Therefore, the fixing member 60 can be easily fitted to the covering portion 52 of the second path limiting member 50.
[0078] (7) The first connecting portion 58 has a first movement limiting portion 76 and a second movement limiting portion 77, which limit the movement of the second connecting portion 62 along the length direction of the second path limiting member 50. According to this structure, the second connecting portion 62 can be prevented from detaching from the first connecting portion 58 by means of the first movement limiting portion 76 and the second movement limiting portion 77.
[0079] (8) The first path limiting member 40 limits the path of the straight portion 11A, which is the straight part of the path of the wire harness body 11. The second path limiting member 50 limits the path of the bent portion 11B, which is the bent part of the path of the wire harness body 11. According to this structure, it is possible to continuously prevent the paths of the straight portion 11A and the bent portion 11B of the wire harness body 11 from deviating from their desired paths.
[0080] This embodiment can be implemented in the following ways. This embodiment and the following variations can be combined and implemented with each other within the scope of technical inconsistency. • The second connecting portion 62 in the above embodiment can be assembled to the first connecting portion 58 along the length direction of the second path limiting member 50, but is not limited thereto. For example, it can be configured such that the second connecting portion 62 can be assembled to the first connecting portion 58 from the radially outer side of the covering portion 52.
[0081] For example, in Figure 6In the configuration shown, the second connecting portion 62 can be fitted to the first connecting portion 58 from the radially outer side of the covering portion 52. In this configuration, the second connecting portion 62 has an inclined surface 86 on the inner circumferential side of the extension 85, the inclined surface 86 being inclined such that its radial thickness decreases towards the tip of the extension 85. In this configuration, when assembling the second connecting portion 62 to the first connecting portion 58, firstly, the tip of the extension 84 is inserted from the outer circumferential side of the covering portion 52 into the second receiving portion 74 from the first receiving portion 73. Then, the extension 85 is inserted from the first receiving portion 73 into the second receiving portion 75. Here, because the inclined surface 86 is formed on the extension 85, it is easy to insert the extension 85 into the interior of the first connecting portion 58. With this configuration, a second connecting part 62 and a first connecting part 58 are also provided locally in the circumferential direction of the second path limiting member 50, thereby enabling the assembly part of the fixing member 60 to be miniaturized in the radial direction.
[0082] • In the covering portion 52, the radial thickness of the portion without the first receiving portion side connecting portion 71 and the first cover side connecting portion 72 can be made thinner than the radial thickness of the portion with the first receiving portion side connecting portion 71 and the first cover side connecting portion 72. This configuration makes it easier to achieve radial miniaturization of the assembly portion of the fixing member 60.
[0083] • The location where the first connecting portion 58 is provided in the covering portion 52 is not limited to the above embodiment. For example, the first receiving portion-side connecting portion 71 and the first cover-side connecting portion 72 can be provided at the other circumferential end 53b of the receiving portion 53 and the other circumferential end 54b of the cover portion 54, respectively. That is, the first connecting portion 58 can be provided on the side of the covering portion 52 opposite to the hinge portion (the locking portion 56 and the claw portion 57 side).
[0084] The number of each of the first receiving-side connecting part 71 and the second receiving-side connecting part 81 is not limited to one as described in the above embodiment, but may be two or more. Similarly, the number of each of the first cover-side connecting part 72 and the second cover-side connecting part 82 is not limited to one as described in the above embodiment, but may be two or more.
[0085] In the above embodiment, either the group consisting of the first receiving portion side connecting portion 71 and the second receiving portion side connecting portion 81, or the group consisting of the first cover side connecting portion 72 and the second cover side connecting portion 82, can be omitted. That is, the covering portion 52 of the first connecting portion 58 can be provided only in either the receiving portion 53 or the cover portion 54.
[0086] The concave-convex relationship between the first connecting portion 58 and the second connecting portion 62 is not limited to the above embodiment. That is, the second connecting portion 62 can be a concave portion, and the first connecting portion 58 can be a convex portion that fits into the second connecting portion 62. With this configuration, the first connecting portion 58 and the second connecting portion 62 can be connected with a simple configuration.
[0087] In the above embodiment, the covering portion 52 has a receiving portion 53 and a cover portion 54, but it is not limited to this. For example, the covering portion 52 can be modified to be a non-deformable cylindrical shape. Furthermore, in the above embodiment, the receiving portion 53 and the cover portion 54 are configured such that the cover portion 54 is connected to the receiving portion 53 via a thin-walled hinge portion 55 to form a single unit. Moreover, the cover portion 54 is locked to the receiving portion 53 by the engagement of the locking portion 56 and the claw portion 57 in the closed state; however, this can be modified so that the receiving portion 53 and the cover portion 54 are fixed by other structures.
[0088] The fixing part 61 in the above embodiment is of the type that is fixed to a bolt B extending from the panel P, but it is not particularly limited to this. It is possible to change the fixing part 61 to, for example, a plate-shaped assembly piece extending from the panel P or a type that is fixed to a hole formed in the panel P.
[0089] The second path limiting member 50 in the above embodiment is formed to limit the path of the curved portion 11B of the wire harness body 11, but it is not limited thereto. For example, the second path limiting member 50 can be changed to a shape that limits the path of the straight portion 11A of the wire harness body 11. In this case, the bending shape in the main body portion 51 of the second path limiting member 50 is changed to a shape that extends along a straight line.
[0090] • 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.
[0091] • The protrusion 45 of the above embodiment can be provided at a position in the circumferential direction of the first path limiting member 40 that is farther away from the insertion port 40X than the top end of the first end 41. • The protrusion 46 of the above embodiment can be provided at a position in the circumferential direction of the first path limiting member 40 that is further away from the insertion port 40X than the top end of the second end 42.
[0092] • The protrusions 45 and 46 of the above embodiment can be provided locally along the length direction of the first path limiting member 40. • At least one of the protrusions 45 and 46 in the above embodiments may be omitted.
[0093] • The shape of the connecting portion 43 in the first path limiting member 40 of the above embodiment is not limited to an arc shape, and can be changed to, for example, an elliptical arc shape or a U-shaped shape. In the above embodiment, the first path limiting member 40 and the second path limiting member 50 are harder than the outer member 30, but this is not a limitation. The hardness of the first path limiting member 40 and the second path limiting member 50 may be the same as or lower than that of the outer member 30. That is, the first path limiting member 40 and the second path limiting member 50 only need to function to make the wire harness body 11 less prone to bending compared to the state in which the first path limiting member 40 and the second path limiting member 50 are not installed.
[0094] • The external component 30 in the above embodiment may, for example, have a metal layer containing a metallic material provided on the outer surface of a resin-made corrugated pipe. • The external component 30 in the above embodiments is not limited to a bellows, and may be an external component without a large diameter portion 31 and a small diameter portion 32.
[0095] • The outer component 30 of the above embodiment may have a slit extending along the length direction of the outer component 30. • In the above embodiment, the wire 21 is a high-voltage wire, but it is not limited to this. For example, the wire 21 can be a low-voltage wire.
[0096] In the wire component 20 of the above embodiment, the electromagnetic shielding component is specifically embodied as a braided component 25, but it is not limited thereto. For example, the electromagnetic shielding component in the wire component 20 may be specifically embodied as a metal sheet.
[0097] • The braided component 25 in the wire component 20 of the above embodiment can be omitted. In the above embodiment, two wires 21 constituting the wire member 20 are used, but this is not a limitation. The number of wires 21 can be one or more.
[0098] • The configuration relationship between the inverter M1 and the high-voltage battery M2 in vehicle V is not limited to the above implementation method and can be appropriately changed according to the vehicle configuration. In the above embodiment, the multiple vehicle-mounted devices electrically connected to the wiring harness 10 are specifically embodied as an inverter M1 and a high-voltage battery M2, but are not limited thereto. The multiple vehicle-mounted devices electrically connected to the wiring harness 10 can be any electrical machinery mounted on the vehicle V, and are not particularly limited thereto.
[0099] The embodiments and variations disclosed herein are illustrative in all respects, and the invention is not limited to these illustrative examples. That is, the scope of the invention is defined by the scope of the claims, and is intended to include all modifications within the meaning and scope of the claims.
