Description

Technical Field

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

[0002] Previously, a wire harness was known to have the following features: a corrugated tube covering the outer periphery of the wire member; and a path limiting member covering a portion of the circumferential direction of the corrugated tube and limiting the path of the wire member (see, for example, Patent Document 1).

[0003] Patent Document 1 describes a wire harness with a corrugated tube having a slit formed along its length. The path limiting member includes a path maintaining member disposed along the outer periphery of the corrugated tube and a mounting member disposed within the slit. The mounting member is configured to engage with both the inner periphery of the slit and the outer periphery of the path maintaining member. By securing the corrugated tube, the path maintaining member, and the mounting member with a tape wrap, the path of the wire component is limited.

[0004] Furthermore, considering the following structure: the integrated bellows and path limiting components are held together by a belt clamp, which is then fixed to the vehicle body, thereby fixing the wiring harness to the vehicle body.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2013-55760 Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] However, in the structure described above where the path limiting member is held in place by a fixing member such as a clamp, the path limiting member may rotate circumferentially relative to the fixing member. Furthermore, this rotation of the path limiting member relative to the vehicle body can cause parts not covered by the bellows path limiting member to be exposed to the outside, for example, by facing the ground, which can reduce the durability of the wiring harness.

[0010] The purpose of this disclosure is to provide a wiring harness that can suppress the rotation of a path limiting member relative to a fixed member fixed to the vehicle body.

[0011] Solution for solving the problem

[0012] The wire harness disclosed herein comprises: a wire member; a cylindrical outer member covering the outer periphery of the wire member; a path limiting member covering a portion of the circumferential direction of the outer member and extending along the length direction of the outer member to limit the path of the wire member; and a fixing member holding the path limiting member and fixing it to the vehicle body, the path limiting member having: an insertion port extending along the length direction of the path limiting member and throughout the entire length of the path limiting member, configured to allow insertion into the outer member; and a first end and a second end located opposite each other in the circumferential direction of the path limiting member to form the insertion port, the fixing member having an engaging portion protruding toward the insertion port, the engaging portion being able to contact at least one of the first end and the second end in the circumferential direction of the path limiting member.

[0013] Invention Effects

[0014] According to the wiring harness disclosed herein, rotation of the path limiting member relative to a fixed member fixed to the vehicle body can be suppressed. Attached Figure Description

[0021] [Description of embodiments of this disclosure]

[0022] The embodiments of this disclosure are first described in detail.

[0023] The wire harness disclosed herein,

[0024] [1] The device comprises: a wire member; a cylindrical outer casing member covering the outer periphery of the wire member; a path limiting member covering a portion of the outer periphery of the outer casing member in the circumferential direction and extending along the length direction of the outer casing member to limit the path of the wire member; and a fixing member holding the path limiting member and fixing it to the vehicle body, the path limiting member having: an insertion port extending along the length direction of the path limiting member and throughout the entire length of the path limiting member, configured to allow insertion of the outer casing member; and a first end and a second end located opposite each other in the circumferential direction of the path limiting member to form the insertion port, the fixing member having a engaging portion protruding toward the insertion port, the engaging portion being able to contact at least one of the first end and the second end in the circumferential direction of the path limiting member.

[0025] According to this structure, the path limiting member can be subsequently installed on the outer periphery of the outer component through the insertion port. Furthermore, the engaging portion of the fixing member can contact at least one of the first end and the second end forming the insertion port in the circumferential direction of the path limiting member, so the fixing member can hold the path limiting member and suppress the circumferential rotation of the path limiting member relative to the fixing member.

[0026] [2] Preferably, the engaging portion has a narrow width portion that is narrower towards the top when viewed from the length direction of the path limiting member.

[0027] According to this structure, because the engaging part has a narrow width that becomes narrower towards the top when viewed from the length direction of the path limiting member, the engaging part is easy to insert into the insertion port, making assembly easy.

[0028] [3] Preferably, the fixing member has: a main body portion; and a cover portion, which can be fixed to the main body portion and, when fixed to the main body portion, together with the main body portion surrounds and maintains the path limiting member.

[0029] According to this structure, since the fixing member has a main body and a cover, it can be fixed to the main body and together with the main body surrounds and retains the path limiting member in a fixed state, so it can be subsequently installed on the path limiting member.

[0030] [4] Preferably, the engaging portion protrudes from the body-opposing portion that faces the mounting surface of the body.

[0031] According to this structure, because the engaging portion protrudes from the body-facing portion opposite to the mounting surface of the vehicle body, the insertion port of the path limiting member faces the mounting surface side. Therefore, it is possible to prevent, for example, the insertion port from facing downwards in a manner opposite to the ground.

[0032] [5] Preferably, a plurality of the fixing members are provided in the length direction of the path limiting member.

[0033] According to this structure, because multiple fixing members are provided along the length of the path limiting member, the circumferential rotation of the path limiting member relative to the fixing members can be suppressed at multiple points along the length of the path limiting member. Therefore, the rotation of the path limiting member can be suppressed more firmly.

[0034] [6] Preferably, the outer component is a corrugated tube having a corrugated structure with annular protrusions and annular recesses alternately and continuously arranged along the length direction of the outer component, and the engaging part has a protrusion that enters into the annular recess.

[0035] According to this structure, since the engaging part has a protrusion that enters the annular recess of the bellows, the movement of the bellows relative to the fixed member can be suppressed in the longitudinal direction of the bellows.

[0036] [7] Preferably, the device includes a sliding limiting member that restricts the movement of the path limiting member relative to the outer component in the length direction of the outer component, and the path limiting member is allowed to move relative to the fixed component in the length direction of the outer component when the sliding limiting member is not installed.

[0037] According to this structure, the movement of the path limiting member relative to the outer component is restricted in the longitudinal direction of the outer component by means of a sliding limiting member. Furthermore, when the sliding limiting member is not installed, the path limiting member is allowed to move relative to the fixed member in the longitudinal direction of the outer component, thus allowing adjustment of the position of the path limiting member.

[0038] [8] Preferably, the path limiting member has a protrusion that protrudes from the inner surface of at least one of the first end and the second end toward the outer component and contacts the outer surface of the outer component.

[0039] According to this structure, the path limiting member has a protrusion that protrudes from the inner surface of at least one of the first end and the second end and contacts the outer surface of the outer component, thus preventing the path limiting member from detaching from the outer component through the insertion port.

[0040] [9] Preferably, the protrusion protrudes from the inner surface of the tip of at least one of the tip of the first end and the tip of the second end.

[0041] According to this structure, for example, compared to the case where the protrusion protrudes from the inner surface at a position slightly away from the top of the first end or the top of the second end, the path limiting member can be more effectively prevented from detaching from the outer component through the insertion port.

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

[0043] Specific examples of the wiring harnesses of this disclosure are described below with reference to the accompanying drawings. In the drawings, for ease of explanation, sometimes a portion of the structure is shown enlarged or simplified. The dimensional ratios of the various parts sometimes differ in the drawings. Furthermore, this disclosure is not limited to these examples, but is intended by the claims to include all modifications within the meaning and scope equivalent to the claims. The term "orthogonal" in this specification includes not only strictly orthogonal cases, but also cases that are substantially orthogonal to the extent that they achieve the desired effect in this embodiment.

[0044] (Overall structure of wire harness 10)

[0045] Figure 1 The wiring harness 10 shown connects two or more electrical devices. For example, the wiring harness 10 connects an inverter 11 located at the front of a vehicle V, such as a hybrid vehicle or electric vehicle, to a high-voltage battery 12 located at the rear of the vehicle V, closer to the inverter 11. The wiring harness 10 is laid out, for example, passing under the floor of the vehicle V. For instance, the middle portion of the wiring harness 10 along its length is laid out outside the vehicle compartment, such as under the floor of the vehicle V.

[0046] Inverter 11 is connected to an electric motor (not shown) for driving the wheels, which serves as the power source for the vehicle. Inverter 11 generates alternating current from the direct current (DC) power of high-voltage battery 12 and supplies this AC power to the electric motor. High-voltage battery 12 is, for example, a battery capable of supplying several hundred volts.

[0047] like Figure 1 and Figure 2 As shown, the wiring harness 10 includes: a wire member 20 for electrically connecting the aforementioned electrical devices to each other; a cylindrical outer member 30 for covering the outer periphery of the wire member 20; and a path limiting member 40 for covering the outer periphery of the outer member 30 and limiting the path (hereinafter referred to as the laying path) of the wire member 20.

[0048] In addition, such as Figure 3 As shown, the wiring harness 10 includes a fixing member 50, which holds the path limiting member 40 and is fixed to the body V1 of the vehicle V. A pair of connectors C1 and C2 are installed at both ends of the wiring member 20.

[0049] (Structure of electrical component 20)

[0050] The wiring component 20 has one or more wires 21 and a braided component 24 that covers the outer circumference of each wire 21. In this embodiment, the wiring component 20 has two wires 21. One end of the wiring component 20 is connected to the inverter 11 via connector C1, and the other end is connected to the high-voltage battery 12 via connector C2. The wiring component 20 is formed in an elongated shape, for example, extending in the longitudinal direction of the vehicle. The wires 21 are, for example, high-voltage wires capable of handling high voltage and high current. The wires 21 can be, for example, unshielded wires without electromagnetic shielding or shielded wires with electromagnetic shielding.

[0051] (Structure of wire 21)

[0052] like Figure 2 As shown, the wire 21 is a sheathed wire having a core wire 22 made of conductor and an insulating sheath 23 covering the outer periphery of the core wire 22.

[0053] (Structure of core wire 22)

[0054] As the core wire 22, for example, a stranded wire formed by twisting multiple metal wires together, a cylindrical conductor consisting of a single metal rod with a solid internal structure, or a cylindrical conductor with a hollow internal structure can be used. Alternatively, a core wire composed of a combination of various conductors such as stranded wire, cylindrical conductor, and tubular conductor can also be used as the core wire 22. Examples of cylindrical conductors include single-core wires and busbars. In this embodiment, the core wire 22 is a stranded wire. As the material for the core wire 22, copper-based or aluminum-based metal materials can be used, for example.

[0055] The cross-sectional shape (hereinafter referred to as the cross-sectional shape) of the core wire 22 cut by a plane orthogonal to the length direction of the core wire 22, i.e., the length direction of the wire 21, can be any shape. The cross-sectional shape of the core wire 22 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 the core wire 22 is formed as a circle.

[0056] (Structure of insulating covering part 23)

[0057] The insulating covering portion 23, for example, covers the entire outer periphery of the core wire 22. The insulating covering portion 23 is, for example, made of an insulating material such as synthetic resin. As the material for the insulating covering portion 23, for example, a synthetic resin whose main component is a polyolefin resin such as cross-linked polyethylene or cross-linked polypropylene can be used. Furthermore, as the material for the insulating covering portion 23, either a single material can be used, or two or more materials can be appropriately combined.

[0058] (Structure of braided component 24)

[0059] The braided member 24 is, for example, formed in a cylindrical shape that covers the outer periphery of each wire 21. The braided member 24 is arranged such that it substantially covers the outer periphery of each wire 21 along its length. As the braided member 24, a braided wire made of multiple metal wires or a braided wire made of a combination of metal wires and resin wires can be used. As the material of the metal wires, copper-based, aluminum-based, or other similar metal materials can be used. Although not shown in the diagram, the braided member 24 is grounded at each connector C1, C2, etc.

[0060] (Structure of external component 30)

[0061] like Figure 3 As shown, the outer casing 30 is formed into a cylindrical shape that completely covers the outer periphery of the wire component 20 in the circumferential direction. The outer casing 30 is completely sealed in the circumferential direction. For example, the outer casing 30 is provided in a manner that covers a portion of the outer periphery of the wire component 20 in the longitudinal direction. In this embodiment, the outer casing 30 is a corrugated tube having a corrugated structure with annular protrusions 31 and annular recesses 32 alternately and continuously provided along its longitudinal direction. The outer casing 30 is flexible.

[0062] The material used for the outer component 30 can be a conductive resin material or a non-conductive resin material. For example, synthetic resins such as polyolefins, polyamides, polyesters, and ABS resins can be used as resin materials.

[0063] (Structure of path restriction component 40)

[0064] like Figure 2 and Figure 4 As shown, the path limiting member 40 covers a portion of the circumferential direction of the outer periphery of the outer component 30 and extends along the length direction of the outer component 30. Furthermore, the path limiting member 40 covers more than half of the outer periphery of the outer component 30. In this embodiment, the path limiting member 40 is installed, for example, on the outer periphery of a linearly extending portion of the outer component 30, such as in the wiring path of the wiring component 20 or under the floor of the vehicle V.

[0065] The 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 path limiting member 40. The path limiting member 40 can be manufactured by known manufacturing methods such as extrusion molding and injection molding. The cross-sectional shape of the path limiting member 40 in this embodiment is constant when viewed from the length direction. The path limiting member 40 is an extruded product.

[0066] The path limiting member 40 has: an insertion port 44, which is an opening extending in the length direction of the path limiting member 40; a first end 41 and a second end 42 forming the insertion port 44; and a connecting portion 43 connecting 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 as to cover a portion of the circumferential direction of the outer member 30; a first end 41 and a second end 42 provided at both ends of the connecting portion 43; and an insertion port 44 formed through the first end 41 and the second end 42.

[0067] The first end 41 and the second end 42 are located on opposite sides of each other in the circumferential direction of the path limiting member 40. The first end 41 and the second end 42 are separated from each other in the circumferential direction of the path limiting member 40 by the insertion port 44. The cross-sectional shape of the first end 41, the second end 42 and the connecting part 43 is arc-shaped.

[0068] The path limiting member 40 has a pair of protrusions 45 that protrude toward the inserted outer member 30 and contact the outer surface of the outer member 30, more specifically, the outer surface of the annular protrusion 31. One of the protrusions 45 protrudes from the inner surface of the first end 41. The other of the protrusions 45 protrudes from the inner surface of the second end 42. The protrusions 45 protrude from the inner surfaces of the tip 46 of the first end 41 and the tip 47 of the second end 42. The cross-sectional shape of the protrusions 45 is, for example, semi-circular. Each protrusion 45 extends along the entire length of the path limiting member 40.

[0069] The tip 46 of the first end 41 and the tip 47 of the second end 42 are curved when viewed from the length direction of the path limiting member 40. In other words, the cross-sectional shape of the tip 46 of the first end 41 and the tip 47 of the second end 42 is formed into a curved shape. In detail, the cross-sectional shape of the tip 46 of the first end 41 and the tip 47 of the second end 42 is semi-circular.

[0070] The insertion port 44 extends along the length of the path limiting member 40 and covers the entire length of the path limiting member 40. The opening width of the insertion port 44, i.e., the shortest distance between the first end 41 and the second end 42, is less than the outer diameter of the outer member 30.

[0071] When the outer component 30 is inserted into the insertion port 44 from a direction orthogonal to the length direction, the path limiting member 40 elastically deforms, increasing the opening width of the insertion port 44. When the outer component 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 becomes smaller than the outer diameter of the outer component 30, thus the path limiting member 40 is mounted on the outer component 30.

[0072] (Structure of fixed component 50)

[0073] like Figure 3 As shown, the fixing member 50 holds the path-limiting member 40 mounted on the outer component 30 and is fixed to the mounting surface V2 of the vehicle body V1. In this embodiment, the mounting surface V2 is the surface outside the passenger compartment below the floor of the vehicle V, facing the ground. Multiple fixing members 50 are provided along the length of the path-limiting member 40. In this embodiment, two fixing members 50 are provided along the length of the path-limiting member 40.

[0074] like Figures 3-5 As shown, the fixing member 50 is made of resin. The fixing member 50 has a main body 51 and a cover 52. The cover 52 can be fixed to the main body 51, and together with the main body 51, surrounds the retaining path limiting member 40 in a fixed state.

[0075] If we go into detail, such as Figure 5 As shown, the main body 51 has an arc-shaped portion 53 that is formed to cover a portion of the outer periphery of the path limiting member 40 when viewed from the length direction of the path limiting member 40, and a fixing portion 54 provided at one end of the arc-shaped portion 53.

[0076] The fixing part 54 is formed in a roughly quadrangular prism shape. For example... Figure 3 and Figure 4 As shown, the fixing part 54 has a fixing hole 55 extending through in a direction orthogonal to the mounting surface V2. Additionally, a claw-locking part 56 is provided in the fixing part 54.

[0077] like Figure 5 As shown, the cover portion 52 has a cover arc portion 57 formed in an arc shape when viewed from the length direction of the path limiting member 40 so as to cover a part of the outer periphery of the path limiting member 40, and an extension portion 58 provided at one end of the cover arc portion 57.

[0078] The cover portion 52 is connected to the main body portion 51 via a hinge portion 59. Specifically, the other end of the arcuate portion 53 in the main body portion 51 and the other end of the cover arcuate portion 57 in the cover portion 52 are connected via the hinge portion 59. In this embodiment, the hinge portion 59 is a thin-walled portion. The main body portion 51 and the cover portion 52 are integrally formed using the hinge portion 59. The main body portion 51 and the cover portion 52 can rotate relative to each other around the hinge portion 59.

[0079] Furthermore, the cover portion 52 is formed into a closed state by rotating relative to the main body portion 51, thereby surrounding the path limiting member 40 together with the main body portion 51. Additionally, the cover portion 52 is formed into an open state by rotating relative to the main body portion 51, thereby allowing the path limiting member 40 to be externally positioned between the cover portion 52 and the main body portion 51. An extension portion 58 in the cover portion 52 is provided with a claw portion 60 that can engage with a claw locking portion 56 in the main body portion 51. The claw portion 60 engages with the claw locking portion 56 when the cover portion 52 is in the closed state. Thus, when the cover portion 52 is fixed to the main body portion 51 by engaging the claw portion 60 with the claw locking portion 56, the cover portion 52, together with the main body portion 51, can surround and retain the path limiting member 40. Furthermore, as... Figure 3 and Figure 4 As shown, the extension 58 is provided with a communication hole 61 that communicates with the fixing hole 55 of the fixing part 54 in the closed state.

[0080] like Figure 3 As shown, the fixing member 50 is fixed to the vehicle body V1 in a state where the cover portion 52 is in contact with the mounting surface V2 of the vehicle body V1. For example, a fixing piece 62 extending in a direction orthogonal to the mounting surface V2 and in the ground direction is provided on the mounting surface V2. Furthermore, the fixing member 50 is fixed to the mounting surface V2 by passing through the connecting hole 61 and the fixing hole 55 through the fixing piece 62 and engaging with the edge of the fixing hole 55.

[0081] like Figure 5 As shown, the fixing member 50 has a locking portion 63 that protrudes toward the insertion port 44 of the retaining path limiting member 40. In other words, the fixing member 50 has a locking portion 63 that protrudes in a manner disposed inside the insertion port 44 of the retaining path limiting member 40. The locking portion 63 can contact the first end 41 and the second end 42 in the circumferential direction of the path limiting member 40. The locking portion 63 is disposed in the circumferential direction between the first end 41 and the second end 42 of the path limiting member 40, and when the path limiting member 40 is about to rotate circumferentially relative to the fixing member 50, it contacts the first end 41 or the second end 42 to limit the rotation of the path limiting member 40.

[0082] A engaging portion 63 is provided on the cover portion 52. Specifically, the engaging portion 63 protrudes from the body-facing portion 64 opposite the mounting surface V2 of the body V1 towards the insertion port 44 within the cover portion 52. In other words, the engaging portion 63 protrudes from the mounting surface V2 side of the body V1. The engaging portion 63 protrudes towards the ground. Therefore, the insertion port 44 of the path-limiting member 40 faces upwards towards the mounting surface V2 side.

[0083] like Figure 6As shown, the engaging portion 63 has a protrusion 65 that enters into the annular recess 32 of the outer member 30. The protrusion 65 further protrudes from the engaging portion 63. Multiple protrusions 65 are provided in the longitudinal direction of the outer member 30. In this embodiment, five protrusions 65 are provided in the longitudinal direction of the outer member 30, each entering into the annular recess 32 of the outer member 30. Therefore, movement of the outer member 30 relative to the fixing member 50 can be suppressed in the longitudinal direction of the outer member 30.

[0084] like Figure 5 As shown, the engaging portion 63 has a narrow width portion 66 that becomes narrower towards the top when viewed from the length direction of the path limiting member 40. In this embodiment, the narrow width portion 66 is provided on the protrusion 65. In other words, when viewed from the length direction of the path limiting member 40, the protrusion 65 becomes narrower towards the top, thus forming the narrow width portion 66.

[0085] like Figure 3 As shown, the wire harness 10 includes a sliding limiting member 70, which restricts the movement of the path limiting member 40 relative to the outer component 30 in the longitudinal direction of the outer component 30. In this embodiment, the sliding limiting member 70 is an adhesive tape. The sliding limiting member 70 restricts the movement of the path limiting member 40 relative to the outer component 30 by wrapping it around both ends of the path limiting member 40 throughout the outer component 30. Without the sliding limiting member 70 installed, the path limiting member 40 is allowed to move relative to the fixing member 50 in the longitudinal direction of the outer component 30. That is, the fixing member 50 and the path limiting member 40 do not have a portion that directly engages in the longitudinal direction of the path limiting member 40. Therefore, without the sliding limiting member 70 installed, the position of the path limiting member 40 relative to the fixing member 50 in the longitudinal direction of the outer component 30 can be adjusted. Furthermore, the engagement portion 63 can also suppress circumferential rotation of the path limiting member 40 relative to the fixing member 50.

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

[0087] According to the wiring harness 10 of this embodiment, the path limiting member 40 can be subsequently installed on the outer periphery of the outer component 30 through the insertion port 44. In other words, the path limiting member 40 can be assembled to the outer component 30 in a direction orthogonal to the length direction of the outer component 30. Because the path limiting member 40 has a pair of protrusions 45 that contact the outer surface of the outer component 30, the path limiting member 40 can be prevented from detaching from the outer component 30 through the insertion port 44.

[0088] Furthermore, by holding the path limiting member 40 installed on the outer component 30 against the fixing member 50, the fixing member 50 is fixed to the vehicle body V1, thereby securing the wiring harness 10. At this time, the engaging portion 63 of the fixing member 50 can contact the first end 41 and the second end 42 forming the insertion port 44 in the circumferential direction of the path limiting member 40, thus suppressing the circumferential rotation of the path limiting member 40 relative to the fixing member 50.

[0089] The effects of this implementation method will be explained.

[0090] (1) The path limiting member 40 can be reattached to the outer periphery of the outer component 30 via the insertion port 44. Furthermore, the engaging portion 63 of the fixing member 50, which holds the path limiting member 40 and fixes it to the vehicle body V1, can contact the first end 41 and the second end 42 forming the insertion port 44 in the circumferential direction of the path limiting member 40. Therefore, the fixing member 50 can hold the path limiting member 40 and suppress circumferential rotation of the path limiting member 40 relative to the fixing member 50. Thus, for example, rotation of the path limiting member 40 due to vibrations during vehicle V's operation can be suppressed, and the insertion port 44 can be prevented from facing downwards relative to the ground. As a result, for example, the ability of the path limiting member 40 to protect the outer component 30 from damage by flying stones can be suppressed, and the durability of the wiring harness 10 can be suppressed. In addition, the fixing member 50, which has a fixing portion 54 for fixing to the vehicle body, has an engaging portion 63 that suppresses rotation of the path limiting member 40; therefore, compared to cases where those functions are achieved with additional components, the number of parts can be reduced.

[0091] (2) The engaging part 63 has a narrow width part 66 that is narrower towards the top when viewed from the length direction of the path limiting member 40, so the engaging part 63 can be easily inserted into the insertion port 44, and assembly becomes easy.

[0092] (3) The fixing member 50 has a main body 51 and a cover 52. The cover 52 can be fixed to the main body 51, and together with the main body 51, it surrounds and retains the path limiting member 40 in a fixed state. Therefore, the fixing member 50 can be subsequently installed on the path limiting member 40. In other words, the fixing member 50 can be assembled to the path limiting member 40 in a direction orthogonal to the length direction of the path limiting member 40.

[0093] (4) The engaging portion 63 protrudes from the body-facing portion 64, which is opposite to the mounting surface V2 of the body V1, so the insertion port 44 of the path limiting member 40 faces the mounting surface V2. Therefore, it can prevent, for example, the insertion port 44 from facing downwards in a manner opposite to the ground.

[0094] (5) Multiple fixing members 50 are provided along the length of the path limiting member 40, thus suppressing the circumferential rotation of the path limiting member 40 relative to the fixing member 50 at multiple points along the length of the path limiting member 40. Therefore, the rotation of the path limiting member 40 can be suppressed more firmly.

[0095] (6) The engaging part 63 has a protrusion 65 that enters the annular recess 32 of the outer member 30, so that the movement of the outer member 30 relative to the fixing member 50 can be suppressed in the length direction of the outer member 30.

[0096] (7) The sliding limiting member 70 restricts the movement of the path limiting member 40 relative to the outer member 30 in the length direction of the outer member 30. Furthermore, the path limiting member 40 is allowed to move relative to the fixed member 50 in the length direction of the outer member 30 when the sliding limiting member 70 is not installed, so the position of the path limiting member 40 can be adjusted.

[0097] (8) The path limiting member 40 has a protrusion 45 that protrudes from the inner surfaces of the first end 41 and the second end 42 and contacts the outer surface of the outer member 30, thereby preventing the path limiting member 40 from detaching from the outer member 30 through the insertion port 44.

[0098] (9) The protrusion 45 protrudes from the inner surface of the top end 46 of the first end 41 and the top end 47 of the second end 42. Therefore, for example, compared to the case where the protrusion 45 protrudes from the inner surface at a position slightly away from the top end 46 of the first end 41 or the top end 47 of the second end 42, the path limiting member 40 can be more effectively prevented from disengaging from the outer member 30 through the insertion port 44.

[0099] <Variation Example>

[0100] This embodiment can be implemented with the following modifications. This embodiment and the following variations can be combined with each other within the scope of technical inconsistency.

[0101] In the above embodiment, the engaging portion 63 has a narrow width portion 66 that becomes narrower towards the top when viewed from the length direction of the path limiting member 40. However, it is not limited to this and may also be configured without the narrow width portion 66. In addition, in the above embodiment, the narrow width portion 66 is provided on the protrusion 65. However, it is not limited to this. For example, the engaging portion 63 itself may be configured as a narrow width portion that becomes narrower towards the top when viewed from the length direction of the path limiting member 40.

[0102] In the above embodiment, the fixing member 50 is configured to have a main body 51 and a cover 52, and is subsequently installed on the path limiting member 40. However, it is not limited to this; for example, the cover 52 may be configured to be immovable in the closed state. In this case, the fixing member cannot be subsequently installed on the path limiting member 40. Specifically, it cannot be assembled from a direction orthogonal to the length direction of the path limiting member 40; the path limiting member 40 must be assembled on the fixing member in the length direction.

[0103] In the above embodiment, the cover portion 52 is connected to the main body portion 51 via the hinge portion 59, but it is not limited to this, and the main body portion 51 and the cover portion 52 may also be separate. In addition, when the main body portion and the cover portion are separate, the cover portion can also be fixed to the main body portion, and it needs to be fixed to the main body portion and together with the main body portion surround the path limiting member 40.

[0104] In the above embodiment, the cover 52 is provided with a claw 60, which is a structure in which the claw 60 is engaged with the claw locking part 56 of the main body 51 when the cover 52 is in the closed state. However, the cover 52 can also be fixed to the main body 51 by other structures.

[0105] In the above embodiment, the engaging portion 63 is provided to protrude from the body-opposing portion 64 opposite to the mounting surface V2 of the body V1, but it is not limited to this and may protrude from other parts.

[0106] In the above embodiment, two fixing members 50 are provided in the length direction of the path limiting member 40, but it is not limited to this. It can also be a structure with one or more three fixing members 50 in the length direction of the path limiting member 40.

[0107] In the above embodiment, the engaging portion 63 is provided with a protrusion 65 that enters the annular recess 32 of the outer member 30, but it is not limited to this and may also be configured without the protrusion 65. Furthermore, the outer member 30 is provided as a bellows having annular protrusions 31 and annular recesses 32 alternately and continuously arranged along its length, but other outer members may also be used. Moreover, in the case where the outer member does not have the annular recess 32, the protrusion 65 is unnecessary, and it is preferable to use other structures to suppress movement of the outer member relative to the fixing member 50 in the length direction.

[0108] In the above embodiment, the wire harness 10 is provided with a sliding limiting member 70, which limits the movement of the path limiting member 40 relative to the outer member 30 in the length direction of the outer member 30. However, it is not limited to this and the structure may also be provided without the sliding limiting member 70. In addition, the sliding limiting member 70 is provided to be tape, but it may also be provided to be a sliding limiting member other than tape.

[0109] In the above embodiment, the path limiting member 40 is allowed to move relative to the fixed member 50 in the longitudinal direction of the outer member 30 when the sliding limiting member 70 is not installed. However, it is not limited to this and can also be configured to not allow movement. That is, the fixed member 50 and the path limiting member 40 can also be configured to have a portion that directly engages with the path limiting member 40 in the longitudinal direction.

[0110] In the above embodiment, the path limiting member 40 is provided with a protrusion 45, which protrudes from the inner surfaces of the first end 41 and the second end 42 and contacts the outer surface of the outer member 30. However, it is not limited to this and may also be provided with a structure without the protrusion 45. Alternatively, the protrusion 45 may protrude from the inner surface at a position slightly away from the top tip 46 of the first end 41 or the top tip 47 of the second end 42.

[0111] In the above embodiment, the fixing member 50 is fixed to the vehicle body V1 by a fixing piece 62 extending from the mounting surface V2 toward the ground. However, it is not limited to this and can be fixed by other structures. For example, the fixing member 50 can be fixed to the mounting surface V2 by other mounting brackets. Alternatively, the fixing member 50 can have a fitting portion that fits into a mounting hole formed in the mounting surface V2, and is fixed to the mounting surface V2 by fitting the fitting portion into the mounting hole.

[0112] The path limiting member 40 can also be made of metal. For example, the path limiting member 40 can be made of a metal material such as iron, copper, or aluminum. In this way, for example, when it is located near a heat source of the vehicle, the internal temperature of the external component 30 and consequently the temperature rise of the wiring component 20 can be suppressed.

[0113] The outer component 30 may also have a metal layer containing a metallic material formed on the outer surface of the bellows. Such a metal layer can be formed, for example, by electroplating. Preferably, the metal layer is formed on the entire outer surface of the annular protrusion 31 and annular recess 32 of the bellows. Preferably, the outermost surface of the metal layer is made of a metallic material such as aluminum, which has low emissivity. With this structure, for example, when positioned close to a heat source of the vehicle, the internal temperature of the outer component 30, and consequently the temperature rise of the wiring component 20, can be suppressed.

[0114] The outer component 30 may also have a slit extending along its entire length. In this case, it is preferable to seal the outer component 30 circumferentially by wrapping a tape around its outer periphery in a manner that seals the slit along its entire length. This prevents a decrease in the water-tightness of the outer component 30 with the slit.

[0115] The wire component 20 may have one wire 21 or more than three wires 21.

[0116] The braided component 24 can also be omitted from the wire component 20.

[0117] The wiring harness 10 may also have multiple path limiting members 40 that are spaced apart from each other in the length direction of the outer component 30.

[0118] The path limiting member 40 is not limited to being installed under the floor of the vehicle V. The path limiting member 40 can be installed in a straight line along the wiring path of the wiring member 20, for example, it can also be installed inside the passenger compartment of the vehicle V.

[0119] like Figure 5 As shown, the top end 46 of the first end 41 and the top end 47 of the second end 42 may also be opposite to the two circumferential ends of the engaging portion 63. Alternatively, with the path limiting member 40 held in the fixed member 50, a circumferential gap may be formed between the first end 41 and the engaging portion 63 and between the second end 42 and the engaging portion 63.

[0120] like Figure 2 As shown, viewed from the length direction of the path limiting member 40, the surface of the tip 46 of the first end 41 can also be an arc shape that is smoothly continuous with the surface of the protrusion 45 of the first end 41. In other words, viewed from the length direction of the path limiting member 40, the tip 46 of the first end 41 and the protrusion 45 can also have arc-shaped surfaces that extend on the same circumference. Similarly, the surface of the tip 47 of the second end 42 can also be an arc shape that is smoothly continuous with the surface of the protrusion 45 of the second end 42. In other words, viewed from the length direction of the path limiting member 40, the tip 47 of the second end 42 and the protrusion 45 can also have arc-shaped surfaces that extend on the same circumference. Furthermore, the first end 41 is sometimes referred to as the first edge, and the second end 42 is sometimes referred to as the second edge. Additionally, one of the pair of protrusions 45 is sometimes referred to as the first protrusion, and the other of the pair of protrusions 45 is sometimes referred to as the second protrusion.

[0121] like Figure 2 and Figure 3As shown, the insertion port 44 can also be a slot that extends linearly along the entire length of the path limiting member 40, with openings at both ends along the length of the path limiting member 40. Alternatively, with the path limiting member 40 fixed to the fixing member 50, the insertion port 44 can be positioned entirely towards the side where the mounting surface V2 is provided, for example, the side opposite to the ground. The path limiting member 40 can also cover the outer component 30 from the side opposite to the mounting surface V2, for example, from the ground side. Sometimes the path limiting member 40 is referred to as a path defining member that defines the path of the wire component 20.

[0122] like Figure 3 and Figure 5 As shown, the engaging portion 63 can also protrude from the vehicle body opposing portion 64 towards the side opposite to the mounting surface V2. Viewed along the length of the path limiting member 40, the top surface of the engaging portion 63 can also be an arc shape disposed on the same circumference as the arc defined on the inner surface of the connecting portion 43. The top surface of the protrusion 65 can also be an arc shape forming part of a circle concentric with the arc defined on the top surface of the engaging portion 63. The radial thickness of the connecting portion 43 can also be the same in the circumferential direction. Figure 6 As shown, it is also possible that, with the path limiting member 40 held in the fixed member 50, at least a portion of the top surface of the protrusion 65 contacts the outer peripheral surface of the annular protrusion 31.

[0123] like Figure 6 As shown, the fixing member 50 may also have a plurality of engaging portions 63 arranged at intervals along the length of the path limiting member 40. The protrusions 65 may also be provided at intervals along the length of the path limiting member 40 that are equal to or integer multiples of the intervals (spacing) between the annular recesses 32. The width of the protrusions 65 along the length direction may also be smaller than the width of the annular recesses 32, i.e., the interval between adjacent annular protrusions 31.

[0124] This disclosure includes the following installation examples. Reference numerals are used to indicate several constituent elements of the illustrated embodiments, not for limitation, but as an aid to understanding. Some of the items described in the following installation examples may be omitted, or several items described in the installation examples may be selected or combined.

[0125] [Note 1] In one aspect of this disclosure, the protrusion (45) protrudes from the inner surfaces of the top ends of the first end (41) and the second end (42), respectively.

[0126] Viewed from the length direction of the path limiting member (40),

[0127] The surface of the top end (46) of the first end (41) can also be a smooth, continuous arc shape with the surface of the protrusion (45).

[0128] The surface of the top end (47) of the second end (42) can also be a smooth, continuous arc shape with the surface of the protrusion (45).

[0129] [Note 2] In one embodiment of this disclosure, the top surface of the engaging portion (63) may also be an arc shape disposed on a circumference that is the same as the arc defined on the inner surface of the connecting portion (43).

[0130] The top surface of the protrusion (65) is an arc shape that forms part of a circle whose arc is concentric with the top surface of the engaging part (63).

[0131] With the path limiting member (40) held in place by the fixing member (50), at least a portion of the top surface of the protrusion (65) contacts the outer peripheral surface of the annular recess (32).

[0132] [Note 3] In one aspect of this disclosure, the fixing member (50) may also have a plurality of the engagement portions (63) arranged at intervals along the length of the path limiting member (40).

[0133] [Note 4] In one aspect of this disclosure, the protrusion (65) may also be provided at intervals equal to or integer multiples thereof in the length direction of the path limiting member (40) from the intervals where the annular recess 32 is provided.
