[0026] [Description of Embodiments of the Present Disclosure]

[0027] First, embodiments of the present disclosure will be described below.

[0028] [1] The wiring harness disclosed herein comprises: an electric wire; a positioning member made of synthetic resin, which is arranged on the outer periphery of the electric wire; an annular electromagnetic wave absorbing member, which has a through hole for the electric wire to pass through and is fixed to the positioning member; and a fixing member, which fixes the positioning member to the electric wire, the positioning member having a main body including an insertion portion inserted into the through hole and a fixing portion protruding from the main body to the outside of the through hole, the fixing member being formed to fasten the electric wire to the fixing portion.

[0029] According to this structure, the insertion portion of the positioning member is inserted inside the through-hole of the electromagnetic wave absorbing component. This allows the synthetic resin positioning member to be sandwiched between the inner circumference of the through-hole and the electrical wire. This prevents direct contact between the inner circumference of the through-hole and the outer circumference of the electrical wire. As a result, even when the electromagnetic wave absorbing component vibrates due to, for example, vehicle movement, damage to the electrical wire caused by contact with the edge of the inner circumference of the through-hole can be prevented.

[0030] Furthermore, the positioning member is fixed to the electric wire by the fixing member, and the electromagnetic wave absorbing member is fixed to the positioning member. Therefore, positional displacement of the positioning member relative to the electric wire can be suppressed, and positional displacement of the electromagnetic wave absorbing member relative to the electric wire can be suppressed.

[0031] Here, the term "ring" in this specification includes a circular ring with a circular outer edge, a ring with an elliptical or oblong outer edge, a polygonal ring with a polygonal outer edge, and a ring with a rounded polygonal outer edge, and refers to a ring whose outer edge is composed of any closed shape connected by straight lines or curves. A "ring" is a shape having a through hole when viewed from above, and includes a ring whose outer edge is the same as the inner circumference of the through hole, and a ring whose outer edge is different from the inner circumference of the through hole. A "ring" includes a ring with a predetermined length extending in the direction of the central axis extending from the center of the through hole, and the length is not limited. In addition, "ring-shaped" in this specification can be regarded as a ring as a whole, and includes shapes such as a C-shaped shape with a cutout in a portion.

[0032] [2] Preferably, the positioning component has a first protrusion, which is arranged between the insertion portion and the fixing portion and protrudes from the outer peripheral surface of the main body in a direction intersecting with the longitudinal direction of the electric wire, and the first protrusion is opposite to the first side surface of the electromagnetic wave absorbing component.

[0033] According to this structure, by bringing the first side surface of the electromagnetic wave absorbing member into contact with the first protrusion, the electromagnetic wave absorbing member can be easily positioned relative to the positioning member. This improves the assembly workability of the wiring harness. Furthermore, by bringing the first side surface of the electromagnetic wave absorbing member into contact with the first protrusion, the relative movement of the electromagnetic wave absorbing member with respect to the positioning member in the longitudinal direction of the wire can be restricted. This effectively suppresses positional deviation of the electromagnetic wave absorbing member relative to the positioning member.

[0034] As used herein, "opposing" means that surfaces or components are in a position facing each other, and includes not only completely facing each other but also partially facing each other. Furthermore, "opposing" as used herein includes both the case where a component different from the two components is interposed between the two components and the case where no component is interposed between the two components.

[0035] [3] Preferably, the first protrusion is formed so that the amount of protrusion from the outer peripheral surface of the main body decreases from the insertion portion side toward the fixing portion side.

[0036] According to this structure, the outer peripheral surface of the first protrusion is formed into a tapered shape. Therefore, even if a woven component that is easily damaged is provided around the outer periphery of the first protrusion, damage to the woven component due to contact with the outer peripheral surface of the first protrusion can be appropriately suppressed.

[0037] [4] Preferably, the main body is in the shape of a tube for the electric wire to pass through, the main body has a slit extending along the axial direction of the main body, and the positioning component has a second protrusion, which protrudes from the outer peripheral surface of the end portion on the opposite side of the fixing portion among the axial ends of the main body in a direction intersecting the axial direction, and the second protrusion is opposite to the second side surface of the electromagnetic wave absorbing component.

[0038] According to this structure, since the insertion portion is formed into a cylindrical shape, it is possible to more appropriately suppress direct contact between the inner peripheral surface of the through hole and the outer peripheral surface of the electric wire, thereby appropriately suppressing damage to the electric wire caused by contact with the edge of the inner peripheral surface of the through hole.

[0039] Furthermore, by bringing the second side surface of the electromagnetic wave absorbing member into contact with the second protrusion, the electromagnetic wave absorbing member can be easily positioned relative to the positioning member. This improves the assembly workability of the wiring harness. Furthermore, by bringing the second side surface of the electromagnetic wave absorbing member into contact with the second protrusion, the relative movement of the electromagnetic wave absorbing member with respect to the positioning member in the longitudinal direction of the wire can be restricted. This effectively suppresses positional deviation of the electromagnetic wave absorbing member relative to the positioning member.

[0040] [5] Preferably, the second protrusion is formed so that the amount of protrusion from the outer peripheral surface of the main body decreases as the distance from the electromagnetic wave absorbing member increases.

[0041] According to this structure, the outer peripheral surface of the second protrusion is formed into a tapered shape. Therefore, even if a woven component that is easily damaged is provided around the outer periphery of the second protrusion, damage to the woven component due to contact with the outer peripheral surface of the second protrusion can be appropriately suppressed.

[0042] [6] Preferably, the second protrusion contacts the second side surface of the electromagnetic wave absorbing member, and the outer peripheral surface of the portion of the second protrusion contacting the second side surface is flush with the outer peripheral surface of the electromagnetic wave absorbing member.

[0043] According to this configuration, the outer peripheral surface of the second protrusion is flush with the outer peripheral surface of the electromagnetic wave absorbing member, and is tapered so that the amount of protrusion decreases as the distance from this flush portion moves away from the electromagnetic wave absorbing member. For example, even if the corners of the electromagnetic wave absorbing member are formed at sharp angles, by tapering the outer peripheral surface of the second protrusion, which is formed continuously with the outer peripheral surface of the electromagnetic wave absorbing member, the corners of the electromagnetic wave absorbing member can be approximately tapered. Thus, even if a braided component, such as a susceptible component, is provided to surround the outer periphery of the electromagnetic wave absorbing member and the second protrusion, damage to the braided component due to contact with the outer peripheral surface of the electromagnetic wave absorbing member and the second protrusion can be appropriately suppressed.

[0044] [7] Preferably, the device further comprises: an electromagnetic shielding component that surrounds the outer periphery of the electric wire, the positioning component, and the electromagnetic wave absorbing component; and a limiting component that covers the outer peripheral surface of the electromagnetic shielding component, wherein the limiting component is formed to tighten the electromagnetic shielding component from the outside of the electromagnetic shielding component toward the electric wire.

[0045] According to this structure, the electromagnetic wave absorbing member and the electromagnetic shielding member surrounding the outer periphery of the electromagnetic wave absorbing member can reduce electromagnetic waves radiated from the electric wire. In addition, since the electromagnetic shielding member is fastened toward the electric wire by the restraining member, the electromagnetic shielding member can be suppressed from expanding radially outward of the electric wire.

[0046] [8] Preferably, the restricting member is provided so as to overlap with the fixing portion in a direction intersecting with the longitudinal direction of the electric wire.

[0047] According to this configuration, the restricting member is provided so as to surround the outer periphery of the fixing portion. Therefore, the restricting member secures the electromagnetic shielding member toward the electrical wires and the fixing portion. In this case, compared to a case where the electromagnetic shielding member is secured only to the outer periphery of the electrical wires, the thickness of the object to which the electromagnetic shielding member is secured increases by an amount corresponding to the thickness of the fixing portion. This reduces the height difference between the outer periphery of the electromagnetic wave absorbing member and the outer periphery of the restricting member. This prevents an increase in the tension applied to the electromagnetic shielding member between the portion surrounding the outer periphery of the electromagnetic wave absorbing member and the portion covered by the restricting member, thereby preventing a reduction in the elasticity of the electromagnetic shielding member in this portion. As a result, wear of the electromagnetic shielding member caused by contact with the outer periphery of the electromagnetic wave absorbing member can be suppressed, thereby preventing damage to the electromagnetic shielding member.

[0048] [9] Preferably, the device further comprises: a first exterior component that accommodates the electric wire; a second exterior component that accommodates the electric wire and is disposed separately from the first exterior component in the longitudinal direction of the electric wire; and a protective component that covers the outer periphery of the electromagnetic wave absorbing component and the positioning component and is fixed in a manner that is spanned between the outer periphery of the first exterior component and the outer periphery of the second exterior component, the electromagnetic wave absorbing component being disposed between the first exterior component and the second exterior component in the longitudinal direction of the electric wire.

[0049] According to this structure, the outer periphery of the electromagnetic wave absorbing member is covered by the protective member, so that the protective member can be interposed between the electromagnetic wave absorbing member and its surrounding components. This can prevent the electromagnetic wave absorbing member from directly contacting the surrounding components, thereby preventing damage to the electromagnetic wave absorbing member caused by contact between the electromagnetic wave absorbing member and the surrounding components.

[0050]

[10] Preferably, the first exterior member is a metal tube, the second exterior member is a synthetic resin exterior member, and the fixing portion is provided between the insertion portion and the second exterior member.

[0051] According to this configuration, the fixing portion is formed to extend from the insertion portion toward the second exterior member. In other words, the fixing portion is formed to extend from the insertion portion in a direction away from the first exterior member, which is a metal tube. Therefore, even if a bracket is attached to the end of a metal tube, for example, interference between the bracket and the fixing portion of the positioning member can be appropriately suppressed.

[0052]

[11] Preferably, the protective member is a waterproof member that waterproofs the member housed inside the protective member, and the fixing member is a belt member wound around the fixing portion and the electric wire.

[0053] With this structure, the positioning member can be secured to the electric wire using the band. Furthermore, since the band is positioned within the waterproof member, contact with liquids such as rainwater and the band can be prevented. This effectively prevents the band's adhesive strength from being reduced due to contact with liquid, thereby maintaining the band's proper fixation to the positioning member and the electric wire.

[0054] [Details of the embodiments of the present disclosure]

[0055] Hereinafter, specific examples of the wiring harness disclosed in the present invention will be described with reference to the accompanying drawings. In each of the drawings, for the sake of convenience of explanation, a part of the structure is sometimes exaggerated or simplified. In addition, the size ratios of each part are sometimes different in each of the drawings. "Parallel" and "orthogonal" in this specification include not only strictly parallel and orthogonal situations, but also roughly parallel and orthogonal situations within the scope of the effects of the present embodiment. In addition, the present invention is not limited to the above examples, but is shown in the claims, and is intended to include all changes within the meaning and scope equivalent to the claims.

[0056] (Overall Structure of Wiring Harness 10)

[0057] Figure 1 The wire harness 10 shown electrically connects two or more electrical devices (equipment). The wire harness 10 electrically connects an inverter 11 provided at the front of a vehicle V such as a hybrid vehicle or an electric vehicle to a high-voltage battery 12 provided at a position further back than the inverter 11 in the vehicle V. The wire harness 10 is wired, for example, so as to pass under the floor of the vehicle V. For example, the wire harness 10 is wired so as to pass under the floor of the vehicle V, for example. The middle portion of the wire harness 10 in the longitudinal direction passes outside the vehicle V, for example. The inverter 11 is connected to a motor (not shown) for driving the wheels, which is a power source for the vehicle. The inverter 11 generates alternating current from the direct current of the high-voltage battery 12, and supplies the alternating current to the motor. The high-voltage battery 12 is, for example, a battery capable of supplying a voltage of several hundred volts.

[0058] The wire harness 10 includes one or more (two in this embodiment) electric wires 20 , a pair of connectors C1 attached to both ends of the electric wires 20 , an exterior member 30 collectively surrounding the plurality of electric wires 20 , and an electromagnetic wave absorbing member 80 .

[0059] (Structure of the Electric Wire 20)

[0060] One end of each wire 20 is connected to the inverter 11 via a connector C1, and the other end of each wire 20 is connected to the high-voltage battery 12 via a connector C1. Each wire 20 is formed, for example, in an elongated strip extending in the front-to-rear direction of the vehicle V. Each wire 20 is formed, for example, to be bent two-dimensionally or three-dimensionally according to the wiring path of the wire harness 10. Each wire 20 is, for example, a high-voltage wire capable of handling high voltage and high current. Each wire 20 can be, for example, a shielded wire with an inherent electromagnetic shielding structure or an unshielded wire without an inherent electromagnetic shielding structure. In this embodiment, each wire 20 is an unshielded wire.

[0061] like Figure 2 As shown, the electric wire 20 is a covered electric wire having a core wire 21 composed of a conductor and an insulating coating 22 covering the outer periphery of the core wire 21 .

[0062] (Structure of Core Wire 21)

[0063] Examples of the core wire 21 include a stranded wire formed by twisting multiple metal wires, a columnar conductor consisting of a single metal rod with a solid interior, and a cylindrical conductor with a hollow interior. For example, a combination of stranded wire, columnar conductors, and cylindrical conductors can be used as the core wire 21. Examples of columnar conductors include single-core wires and busbars. The core wire 21 of this embodiment is a stranded wire. Examples of the material for the core wire 21 include copper-based and aluminum-based metal materials.

[0064] The cross-sectional shape (i.e., cross-sectional shape) obtained by cutting the core wire 21 along a plane perpendicular to the longitudinal direction of the core wire 21 can be set to any shape. The cross-sectional shape of the core wire 21 is formed into, for example, a circular, semicircular, polygonal, square, or flat shape. The cross-sectional shape of the core wire 21 in this embodiment is formed into a circular shape.

[0065] (Structure of the Insulating Coating 22)

[0066] The insulating coating 22, for example, covers the entire circumference of the outer surface of the core wire 21. The insulating coating 22 is made of, for example, an insulating material such as a synthetic resin. For example, a synthetic resin primarily composed of a polyolefin resin such as cross-linked polyethylene or cross-linked polypropylene can be used as the material for the insulating coating 22. A single material can be used for the insulating coating 22, or two or more materials can be used in appropriate combinations. The insulating coating 22 can be formed, for example, by extrusion molding (extrusion coating) of the core wire 21.

[0067] (Structure of Exterior Member 30)

[0068] The exterior member 30 is generally elongated and cylindrical in shape. Multiple electrical wires 20 are housed within the interior of the exterior member 30. The exterior member 30 is formed, for example, to completely surround the outer periphery of the multiple electrical wires 20. The exterior member 30 protects the electrical wires 20 from, for example, flying objects and water droplets. Examples of the exterior member 30 include a metal or resin tube, a resin protector, a flexible bellows made of resin or the like, a rubber waterproof cover, or a combination thereof.

[0069] The exterior member 30 includes, for example, a metal pipe 40 , a bellows 50 , and a protective member 60 .

[0070] (Structure of the tube 40)

[0071] The tube 40 is, for example, in the shape of a cylinder that surrounds the outer circumference of the plurality of wires 20 as a whole. The tube 40 is, for example, arranged to surround the outer circumference of the plurality of wires 20 throughout the entire circumference. The tube 40 is, for example, arranged to surround a portion of the longitudinal direction (axial direction) of the wires 20. The outer circumferential surface of the tube 40 is, for example, formed into a smooth surface. The tube 40 of this embodiment is formed into a cylindrical shape. The material of the tube 40 can be, for example, a metal material such as copper or aluminum. The tube 40 has the function of electromagnetically shielding the plurality of wires 20 as a whole and protecting the plurality of wires 20 from flying objects and water droplets.

[0072] A pair of mounting holes 41 are formed at the ends of the tube 40. Each mounting hole 41 is formed to penetrate the tube 40 in the radial direction of the tube 40. Each mounting hole 41 is provided at a position away from an end surface 42 of the tube 40 in the longitudinal direction (axial direction).

[0073] A bracket 70 made of, for example, synthetic resin is attached to the end of the tube 40. The bracket 70 is formed, for example, so as to collectively surround a plurality of electrical wires 20. The bracket 70 is inserted into the interior of the tube 40 and attached to the end of the tube 40. The bracket 70 is disposed inside the metal tube 40, for example, to protect the insulating coating 22 of the electrical wires 20 from the edge of the open end of the tube 40. The bracket 70 can be made of, for example, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin.

[0074] (Structure of the bracket 70)

[0075] Bracket 70 includes, for example, a cylindrical main body 71, a pair of protrusions 72 formed on the outer peripheral surface of main body 71, and a projection 73 formed on the outer peripheral surface of main body 71. Bracket 70 is, for example, a single member in which main body 71, protrusions 72, and projection 73 are integrally formed from a synthetic resin material.

[0076] The main body 71 fits inside the tube 40. The main body 71 is formed to conform to the inner circumference of the tube 40. In this embodiment, the main body 71 is generally cylindrical. The outer diameter of the main body 71 is, for example, slightly smaller than the inner diameter of the tube 40. Although not shown in the figure, a slit extending along the entire axial length of the main body 71 is formed in the main body 71.

[0077] Each protrusion 72 is formed, for example, to protrude radially outward from the outer peripheral surface of one axial end portion of the main body 71. Each protrusion 72 is, for example, engaged with a mounting hole 41 of the pipe 40. By engaging the protrusion 72 with the mounting hole 41, the bracket 70 is fixed to the end portion of the pipe 40.

[0078] The protrusion 73 is formed, for example, so as to protrude radially outward from the outer circumferential surface of the axial end portion of the main body 71, the end portion opposite the protrusion 72. The protrusion 73 is formed, for example, so as to extend along the circumference of the main body 71. For example, the protrusion 73 is formed over the entire circumferential length of the main body 71. The protrusion 73 is opposed to the axial end surface 42 of the tube 40, for example. The protrusion 73 is in contact with the axial end surface 42 of the tube 40.

[0079] (Structure of the bellows 50)

[0080] The corrugated tube 50 is, for example, provided separately from the tube 40 in the longitudinal direction of the wires 20. The corrugated tube 50 is, for example, provided between the tube 40 and the connector C1. The end of the corrugated tube 50 is, for example, connected to the connector C1. The corrugated tube 50 is, for example, formed as a whole into a cylindrical shape that collectively surrounds the outer circumference of the plurality of wires 20. The corrugated tube 50 is, for example, provided so as to surround the outer circumference of the plurality of wires 20 throughout the entire circumference. The corrugated tube 50 is, for example, provided so as to surround a portion of the longitudinal direction of the wires 20. The corrugated tube 50 has a corrugated structure with annular protrusions 51 and annular recesses 52 alternately provided continuously along its longitudinal direction. The flexibility of the corrugated tube 50 is superior to the flexibility of the core wire 21. The corrugated tube 50 of this embodiment is formed into a cylindrical shape. The material of the corrugated tube 50 can be, for example, a conductive resin material or a non-conductive resin material. The resin material can be, for example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin.

[0081] (Structure of Protective Member 60)

[0082] The protective member 60 is, for example, arranged to span between the outer periphery of the tube 40 and the outer periphery of the corrugated tube 50. The protective member 60 is, for example, cylindrical with both ends open in the longitudinal direction of the electric wire 20. As the material of the protective member 60, for example, a relatively high-hardness elastic material can be used. As the elastic material, for example, rubber or an elastomer such as ethylene propylene rubber can be used.

[0083] (Structure of the wiring harness 10)

[0084] The wire harness 10 includes, for example, a positioning member 90 provided on the outer periphery of the electric wires 20, an electromagnetic wave absorbing member 80 fixed to the positioning member 90, and a fixing member 100 for fixing the positioning member 90 to the electric wires 20. The wire harness 10 includes a braided member 110 surrounding the electric wires 20 and restricting members 120 and 121 covering the outer periphery of the braided member 110.

[0085] (Structure of the Electromagnetic Wave Absorbing Member 80)

[0086] The electromagnetic wave absorbing member 80 is, for example, provided around the outer periphery of the electric wire 20 between the tube 40 and the corrugated tube 50. For example, in the longitudinal direction of the electric wire 20, the tube 40 is provided on one side of the electromagnetic wave absorbing member 80, and the corrugated tube 50 is provided on the other side of the electromagnetic wave absorbing member 80. The electromagnetic wave absorbing member 80 is, for example, provided separately from the tube 40 in the longitudinal direction of the electric wire 20. The electromagnetic wave absorbing member 80 is, for example, provided separately from the corrugated tube 50 in the longitudinal direction of the electric wire 20. The electromagnetic wave absorbing member 80 is, for example, exposed from the tube 40 and the corrugated tube 50. The electromagnetic wave absorbing member 80 is, for example, provided so as to collectively surround the outer peripheries of the plurality of electric wires 20. The electromagnetic wave absorbing member 80 absorbs, for example, a portion of the electromagnetic waves (electromagnetic noise) radiated from the plurality of electric wires 20.

[0087] The electromagnetic wave absorbing member 80, for example, has a through-hole 81 through which the plurality of electrical wires 20 pass collectively. The electromagnetic wave absorbing member 80, for example, has a ring shape due to the through-hole 81. For example, when viewed from above along the longitudinal direction of the electrical wires 20, the electromagnetic wave absorbing member 80 is formed into a ring shape having the through-hole 81 and extending along a predetermined length along a central axis extending along the center axis passing through the center of the through-hole 81. In this embodiment, the central axis direction of the electromagnetic wave absorbing member 80 is set to extend parallel to the longitudinal direction of the electrical wires 20. In the following description, when simply referring to the "central axis direction," this refers to the central axis direction of the electromagnetic wave absorbing member 80.

[0088] The through hole 81 is formed to penetrate the electromagnetic wave absorbing member 80 in the longitudinal direction of the electric wire 20. For example, a plurality of electric wires 20 are provided to penetrate the through hole 81. The inner peripheral surface of the through hole 81 faces the outer peripheral surface of the electric wire 20.

[0089] The electromagnetic wave absorbing component 80 of this embodiment consists solely of a ring-shaped magnetic core 82. The magnetic core 82 of this embodiment is formed in a circular ring shape. The magnetic core 82 is, for example, arranged so as to face the wire 20 across the entire circumference of the wire 20, thereby reducing the electromagnetic waves radiated from the wire 20. For example, the magnetic core 82 absorbs the electromagnetic waves radiated from the wire 20 and converts the energy of these waves into mechanical energy, such as vibration, and heat energy. This reduces the adverse effects of electromagnetic waves radiated from the wire 20 on surrounding equipment.

[0090] The magnetic core 82 is, for example, a formed body containing a soft magnetic material. Examples of soft magnetic materials include iron (Fe), iron alloys, and ferrites. Examples of iron alloys include Fe-silicon (Si) alloys and Fe-nickel (Ni) alloys. Examples of the magnetic core 82 include ferrite cores, amorphous cores, and permalloy cores. The ferrite core is, for example, composed of soft ferrite exhibiting soft magnetic properties. Examples of soft ferrites include ferrites containing nickel (Ni) and zinc (Zn), and ferrites containing manganese (Mn) and zinc (Zn). The material of the magnetic core 82 can be appropriately selected, for example, depending on the frequency band of the electromagnetic noise to be reduced.

[0091] like Figure 3 As shown, the magnetic core 82 of this embodiment is formed continuously throughout the entire circumference, forming a closed loop. That is, the magnetic core 82 of this embodiment is formed into a ring-shaped structure that is connected as a whole without a gap, that is, a ring-shaped structure with the same starting point and end point. In other words, the magnetic core 82 of this embodiment does not form a slit extending along the central axis direction of the electromagnetic wave absorbing component 80. The magnetic core 82 of this embodiment is composed of a single component. In addition, in this embodiment, the magnetic core 82 is composed of a single component, but a plurality of core materials can also be combined to form a ring-shaped magnetic core 82. For example, a pair of core materials with a semicircular cross-section can be combined to form the magnetic core 82 in a circular ring shape.

[0092] like Figure 2 As shown, magnetic core 82 includes, for example, an outer peripheral surface 82A extending in the circumferential direction of magnetic core 82, a side surface 82B extending in the radial direction of magnetic core 82 and facing toward tube 40, and a side surface 82C extending in the radial direction of magnetic core 82 and facing toward bellows 50. Side surfaces 82B and 82C are, for example, provided between outer peripheral surface 82A and the inner peripheral surface of through-hole 81. The outer peripheral dimensions of magnetic core 82 are, for example, set to be larger than the inner peripheral dimensions of tube 40 and bellows 50.

[0093] The magnetic core 82 is provided on the outer peripheral surface of the positioning member 90, for example. The magnetic core 82 is fitted on the outer periphery of the positioning member 90, for example.

[0094] (Structure of Positioning Member 90)

[0095] The positioning member 90 is, for example, provided on the outer periphery of the electric wire 20 between the tube 40 and the corrugated tube 50. For example, in the longitudinal direction of the electric wire 20, the tube 40 is provided on one side of the positioning member 90, and the corrugated tube 50 is provided on the other side of the positioning member 90. The positioning member 90 is, for example, provided separately from the tube 40 in the longitudinal direction of the electric wire 20. The positioning member 90 is, for example, provided separately from the corrugated tube 50 in the longitudinal direction of the electric wire 20. The positioning member 90 is, for example, exposed from the tube 40 and the corrugated tube 50. The positioning member 90 is, for example, fixed to the outer peripheral surface of the electric wire 20. The positioning member 90 is, for example, made of a synthetic resin. As the material of the positioning member 90, for example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin can be used.

[0096] The positioning member 90 includes, for example, a main body 90A including an insertion portion 91 that is inserted into the through-hole 81 of the electromagnetic wave absorbing member 80, and a fixing portion 92 that protrudes from the end surface of the main body 90A. The positioning member 90 also includes, for example, a protrusion 93 that is disposed between the insertion portion 91 and the fixing portion 92 and that protrudes from the outer circumference of the main body 90A in a direction intersecting the longitudinal direction of the electric wire 20, and a protrusion 94 that protrudes from the outer circumference of the end portion of the main body 90A in a direction intersecting the longitudinal direction of the electric wire 20. The positioning member 90 is, for example, a single member in which the insertion portion 91, the fixing portion 92, and the protrusions 93 and 94 are integrally formed from a synthetic resin material.

[0097] (Structure of Main Body 90A)

[0098] The main body 90A is formed into, for example, a cylindrical shape through which the power supply wire 20 passes. The main body 90A is formed into, for example, a cylindrical shape as a whole that collectively surrounds the outer periphery of the plurality of electric wires 20. The main body 90A of this embodiment is formed into a cylindrical shape as a whole.

[0099] like Figure 4 As shown, the main body 90A is formed with, for example, a slit 91X extending in the axial direction of the main body 90A. The slit 91X is formed, for example, to extend along the entire axial length of the main body 90A. In the main body 90A of this embodiment, the slit 91X is formed at one location in the circumferential direction of the main body 90A. Alternatively, the main body 90A may have multiple slits 91X.

[0100] (Structure of Insertion Portion 91)

[0101] like Figure 2As shown, the insertion portion 91 is formed, for example, in the middle portion of the main body 90A in the axial direction. The insertion portion 91 is fitted into the inner side of the through-hole 81. The insertion portion 91 is sandwiched between the inner circumference of the through-hole 81 and the outer circumference of the wire 20. The insertion portion 91 is, for example, cylindrical in shape, surrounding the outer circumference of the plurality of wires 20. The insertion portion 91 is, for example, formed to follow the inner circumference of the through-hole 81. The insertion portion 91 of this embodiment is formed as a whole in a cylindrical shape. The outer diameter of the insertion portion 91 is, for example, slightly smaller than the inner diameter of the through-hole 81. The outer circumference of the insertion portion 91 is in contact with the inner circumference of the through-hole 81. The contact between the outer circumference of the insertion portion 91 and the inner circumference of the through-hole 81 may be in any of the following forms: surface contact, line contact, or point contact. The inner circumference of the insertion portion 91 is, for example, opposed to the outer circumference of the wire 20. For example, the insertion portion 91 is configured to have the slit 91X so that, when inserted into the through-hole 81 , the insertion portion 91 can be elastically deformed so as to reduce the width of the slit 91X and thereby reduce the diameter.

[0102] (Structure of the fixing portion 92)

[0103] The fixing portion 92 is formed to protrude from the main body 90A to the outside of the through hole 81. The fixing portion 92 is formed to extend from the axial end surface of the main body 90A along the axial direction of the main body 90A. The fixing portion 92 is formed to protrude in a direction away from the insertion portion 91. The fixing portion 92 is formed, for example, only on a portion of the circumference of the main body 90A. Figure 4 As shown, the fixing portion 92 is formed at a position offset from the slit 91X in the circumferential direction, for example. The fixing portion 92 is formed at a position offset from the slit 91X in the circumferential direction, for example.

[0104] The fixing portion 92 is formed into a thin plate shape, for example. The fixing portion 92 has a Figure 2 ) and an outer surface opposite to the inner surface. The inner and outer surfaces of the fixing portion 92 are, for example, curved. The inner and outer surfaces of the fixing portion 92 are, for example, arcuate surfaces coaxial with the main body 90A. The inner surface of the fixing portion 92 is, for example, continuous and integral with the inner circumferential surface of the main body 90A without any height difference.

[0105] (Structure of protrusion 93)

[0106] The protrusion 93 is formed, for example, so as to extend radially outward from the outer circumferential surface of one axial end portion of the main body 90A. The protrusion 93 is formed, for example, on the outer circumferential surface of the end portion of the main body 90A that is closer to the fixing portion 92. The protrusion 93 is formed, for example, along the entire circumferential length of the main body 90A. Alternatively, the protrusion 93 may be formed only on a portion of the circumference of the main body 90A.

[0107] like Figure 2 As shown, the protrusion 93 includes a side surface 93A that faces the electromagnetic wave absorbing member 80 and an outer peripheral surface 93B that serves as the protruding front end of the protrusion 93. The side surface 93A is formed, for example, to extend radially and circumferentially relative to the main body 90A. The side surface 93A is formed, for example, to face the side surface 82C of the electromagnetic wave absorbing member 80. The side surface 93A is formed, for example, to contact the side surface 82C of the electromagnetic wave absorbing member 80. The radial thickness of the side surface 93A is formed, for example, to be smaller than the radial thickness of the side surface 82C. Therefore, the side surface 93A faces only a portion of the radial direction of the side surface 82C.

[0108] The outer peripheral surface 93B is the radially outermost surface of the outer surface of the protrusion 93. The outer peripheral surface 93B is formed, for example, to expand in the axial and circumferential directions of the main body 90A. The outer peripheral surface 93B has, for example, an inclined surface 93C that is inclined so as to approach the outer peripheral surface of the main body 90A as it moves from the insertion portion 91 side toward the fixing portion 92 side. In other words, the outer peripheral surface 93B has an inclined surface 93C that is inclined so as to approach the outer peripheral surface of the main body 90A as it moves away from the electromagnetic wave absorbing component 80. In other words, the protrusion 93 is formed so that the amount of radial outward protrusion from the outer peripheral surface of the main body 90A decreases as it moves from the insertion portion 91 side toward the fixing portion 92 side. The inclined surface 93C is provided, for example, on at least a portion of the outer peripheral surface 93B of the protrusion 93.

[0109] (Structure of protrusion 94)

[0110] The protrusion 94 is formed, for example, so as to extend radially outward from the outer circumference of one axial end portion of the main body 90A. The protrusion 94 is formed, for example, on the outer circumference of the end portion of the main body 90A opposite the fixing portion 92 in the axial direction. The protrusion 94 is formed, for example, along the entire circumferential length of the main body 90A. Alternatively, the protrusion 94 may be formed only on a portion of the circumference of the main body 90A.

[0111] The protrusion 94 includes a side surface 94A that faces the electromagnetic wave absorbing member 80 and an outer peripheral surface 94B that serves as the protruding front end of the protrusion 94. For example, the side surface 94A is formed so as to extend radially and circumferentially relative to the main body 90A. For example, the side surface 94A is formed so as to face the side surface 82B of the electromagnetic wave absorbing member 80. For example, the side surface 94A contacts the side surface 82B of the electromagnetic wave absorbing member 80. The radial thickness of the side surface 94A is formed to be, for example, the same length as the radial thickness of the side surface 82B. Therefore, for example, the side surface 94A faces the entire radial length of the side surface 82B. For example, the side surface 94A faces the side surface 93A of the protrusion 93. For example, the thickness of the side surface 94A is formed to be greater than the thickness of the side surface 93A.

[0112] The outer peripheral surface 94B is the radially outermost surface of the outer surface of the protrusion 94. The outer peripheral surface 94B is formed, for example, to expand in the axial and circumferential directions of the main body 90A. The outer peripheral surface 94B includes, for example, an inclined surface 94C that slopes toward the outer peripheral surface of the main body 90A as it moves away from the electromagnetic wave absorbing member 80. In other words, the protrusion 94 is formed so that the amount of radial outward protrusion decreases as it moves away from the electromagnetic wave absorbing member 80. The inclined surface 94C is provided, for example, on at least a portion of the outer peripheral surface 94B of the protrusion 94. Here, the portion of the outer peripheral surface 94B closest to the side surface 82B of the electromagnetic wave absorbing member 80 is, for example, flush with the outer peripheral surface 82A of the electromagnetic wave absorbing member 80. That is, the portion of the outer peripheral surface 94B of the protrusion 94 that contacts the side surface 82B of the electromagnetic wave absorbing member 80 is flush with the outer peripheral surface 82A of the electromagnetic wave absorbing member 80.

[0113] The positioning member 90 is attached to the electromagnetic wave absorbing member 80 by, for example, inserting the insertion portion 91 into the through-hole 81 of the electromagnetic wave absorbing member 80 from the side surface 82B toward the side surface 82C. At this point, the main body 90A, including the insertion portion 91, elastically deforms to reduce the width of the slit 91X and its diameter. Furthermore, when the protrusion 93 at the end of the main body 90A passes through the through-hole 81, the main body 90A elastically returns to its original shape, i.e., the width of the slit 91X widens. As a result, the side surface 93A of the protrusion 93 contacts the side surface 82C of the electromagnetic wave absorbing member 80, and the protrusion 93 is locked to the electromagnetic wave absorbing member 80. Furthermore, the side surface 94A of the protrusion 94 contacts the side surface 82B of the electromagnetic wave absorbing member 80, and the protrusion 94 is locked to the electromagnetic wave absorbing member 80. This prevents the positioning member 90 from being dislodged from the through-hole 81, and restricts relative movement of the electromagnetic wave absorbing member 80 with respect to the positioning member 90 in the longitudinal direction of the positioning member 90. In other words, the electromagnetic wave absorbing member 80 is fixed to the positioning member 90 by the protrusions 93 and 94 provided on both sides of the electromagnetic wave absorbing member 80. In this case, the fixing portion 92 of the positioning member 90 is provided, for example, between the main body 90A and the corrugated tube 50. The fixing portion 92 is formed, for example, to extend from the main body 90A toward the corrugated tube 50. In other words, the fixing portion 92 is formed to extend from the main body 90A in a direction away from the tube 40. This prevents interference between the bracket 70 attached to the end of the tube 40 and the fixing portion 92.

[0114] (Structure of the fixing member 100)

[0115] The fixing member 100 is provided, for example, to fix the positioning member 90 to the plurality of electric wires 20. The fixing member 100 is provided, for example, to fix the fixing portion 92 of the positioning member 90 to the plurality of electric wires 20. The fixing member 100 has a function of restricting relative movement of the positioning member 90 with respect to the electric wires 20 in the longitudinal direction of the electric wires 20.

[0116] The fixing member 100 is formed, for example, by wrapping a tape member 101 around the fixing portion 92 and the electric wire 20. The tape member 101 has, for example, an adhesive layer on one surface. The tape member 101 is wrapped around the fixing portion 92 and the electric wire 20, for example, with the adhesive layer facing radially inward. The tape member 101 is wrapped, for example, over the outer surface of the fixing portion 92 and the outer circumferential surface of the electric wire 20.

[0117] Although not shown in the figure, the tape member 101 has, for example, an overlapping winding structure. Here, the overlapping winding structure refers to a structure in which the tape member 101 is spirally wound so that predetermined portions in the width direction of the tape member 101 overlap. The width direction of the tape member 101 is a direction extending along the longitudinal direction of the electric wire 20. As an example of an overlapping winding structure, a half-overlapping winding structure is preferred. Here, the half-overlapping winding structure refers to a structure in which the tape member 101 is spirally wound so that approximately half of the width direction of the tape member 101 overlaps.

[0118] The band member 101 is formed, for example, to fasten the fixing portion 92 and the electric wires 20. The band member 101 covers, for example, the outer surface of the fixing portion 92 and the outer peripheral surfaces of the plurality of electric wires 20 so as to fasten the fixing portion 92 and the plurality of electric wires 20 in a direction toward each other. The band member 101 is formed, for example, to fasten the fixing portion 92 and the electric wires 20 so that the inner surface of the fixing portion 92 contacts the outer peripheral surfaces of the electric wires 20.

[0119] The belt member 101 fixes the fixing portion 92 to the outer circumference of the electric wire 20, for example, so that the electric wire 20 is arranged inside the insertion portion 91 with a bias toward a portion of the circumference of the insertion portion 91. For example, the belt member 101 is wrapped around the fixing portion 92 and the outer circumferential surface of the electric wire 20 so that the electric wire 20 contacts the inner surface of the fixing portion 92 and is biased toward the fixing portion 92.

[0120] When the positioning member 90 is fixed to the electric wire 20 by the belt member 101, the electromagnetic wave absorbing member 80 fixed to the positioning member 90 is also fixed to the electric wire 20. This restricts the relative movement of the electromagnetic wave absorbing member 80 with respect to the electric wire 20 in the longitudinal direction of the electric wire 20, thereby suppressing positional displacement of the electromagnetic wave absorbing member 80.

[0121] (Structure of Knitted Component 110)

[0122] The braided component 110 is, for example, formed as a whole into a cylindrical shape that surrounds the outer periphery of the plurality of electrical wires 20. The braided component 110 is, for example, provided so as to surround the outer periphery of the electrical wires 20 over substantially the entire length of the electrical wires 20 in the longitudinal direction. As the braided component 110, a braided component formed by braiding a plurality of metal wires or a braided component formed by combining metal wires with resin wires can be used. As the material of the metal wires, for example, copper-based, aluminum-based, and other metal materials can be used. As the resin wires, for example, reinforcing fibers having excellent insulation and shear resistance, such as para-aramid fibers, can be used.

[0123] The braided component 110 is formed, for example, so as to collectively surround the outer circumferences of the plurality of electrical wires 20 within the interior space of the corrugated tube 50. In other words, the corrugated tube 50 is configured to surround the electrical wires 20 and the outer circumference of the braided component 110. The braided component 110 is formed, for example, so as to surround the outer circumferences of the electromagnetic wave absorbing component 80 and the positioning component 90 between the tube 40 and the corrugated tube 50. The braided component 110 is formed, for example, so that the portion covering the electromagnetic wave absorbing component 80 and the positioning component 90 is larger than the outer circumference of the other portions. The braided component 110 is configured, for example, so as to surround the outer circumferences of the electrical wires 20, the positioning component 90, the electromagnetic wave absorbing component 80, and the fixing component 100 throughout the entire circumference of the interior space of the protective component 60.

[0124] The axial end of the braided component 110 is electrically connected to the outer circumferential surface of the tube 40, for example. The axial end of the braided component 110 is connected to the outer circumferential surface of the tube 40, for example, by a caulking ring 115 provided on the outer circumference of the braided component 110, while in direct contact with the outer circumferential surface of the tube 40. The caulking ring 115 is fitted onto the outer side of the tube 40, for example, so that the end of the braided component 110 is sandwiched between the outer circumferential surface of the tube 40. Furthermore, by tightening the caulking ring 115 radially inwardly of the tube 40, the end of the braided component 110 is secured in direct contact with the outer circumferential surface of the tube 40. This ensures stable electrical conduction between the braided component 110 and the tube 40. The caulking ring 115 is provided on the outer circumferential surface of the tube 40, for example, between the end face 42 of the tube 40 and the mounting hole 41. The end of the braided component 110 is folded back toward the corrugated tube 50 and radially outward. The folded braided component 110, for example, surrounds the outer circumference of the caulking ring 115. Although not shown in the drawings, the end portion on the connector C1 side among the axial end portions of the braided component 110 is grounded (connected to ground) at, for example, the connector C1 or the like.

[0125] Copper, iron, or aluminum-based metals can be used as the material of the caulking ring 115 . The caulking ring 115 is preferably made of the same metal as the metal constituting the pipe 40 .

[0126] (Structure of Restriction Members 120 and 121)

[0127] The limiting members 120 and 121 are formed, for example, to tighten the braided member 110 from the outside toward the electric wire 20. The limiting members 120 and 121 are formed, for example, to tighten the braided member 110 radially inward. The limiting members 120 and 121 have the function of, for example, restricting the braided member 110 from expanding radially outward from the electric wire 20. The limiting members 120 and 121 have the function of, for example, restricting the relative movement of the braided member 110 with respect to the electromagnetic wave absorbing member 80 in the longitudinal direction of the electric wire 20.

[0128] The restricting members 120 and 121 are formed, for example, by wrapping a tape member 122 around the outer circumferential surface of the knitting member 110. The tape member 122 has, for example, an adhesive layer on one surface. The tape member 122 is wrapped around the knitting member 110, for example, with the adhesive layer facing radially inward. Although not shown, the tape member 122 has, for example, an overlapping and wound structure.

[0129] The limiting member 120 is provided, for example, on the outer peripheral surface of the braided member 110 located between the electromagnetic wave absorbing member 80 and the corrugated tube 50. The limiting member 120 is provided, for example, so as to overlap with the fixing portion 92 in a direction intersecting the longitudinal direction of the electric wire 20. The limiting member 120 is provided, for example, so as to overlap with the fixing member 100 in a direction intersecting the longitudinal direction of the electric wire 20.

[0130] The restriction member 121 is provided on the outer peripheral surface of the braided member 110 between the electromagnetic wave absorbing member 80 and the tube 40 , for example. The restriction member 121 is provided on the outer peripheral surface of the braided member 110 between the positioning member 90 and the stent 70 , for example.

[0131] For example, the limiting components 120 and 121 do not surround the outer circumference of the electromagnetic wave absorbing component 80. In this embodiment, the limiting components 120 and 121 do not cover the outer circumference of the portion of the braided component 110 that covers the outer circumferential surface 82A of the magnetic core 82. That is, the electromagnetic wave absorbing component 80 of this embodiment is not fixed to the electric wire 20 by the limiting components 120 and 121. The electromagnetic wave absorbing component 80 of this embodiment is secured radially inward by the braided component 110, which is secured radially inward by the limiting components 120 and 121 provided on both sides of the electromagnetic wave absorbing component 80. This suppresses relative movement of the electromagnetic wave absorbing component 80 with respect to the electric wire 20. That is, even when the electromagnetic wave absorbing component 80 itself is not secured to the electric wire 20, relative movement of the electromagnetic wave absorbing component 80 with respect to the electric wire 20 can be suppressed.

[0132] (Structure of Protective Member 60)

[0133] The protective member 60 is provided, for example, so as to surround the outer periphery of the electromagnetic wave absorbing member 80. The protective member 60 functions as, for example, a waterproof cover for waterproofing various components arranged inside the protective member 60.

[0134] The protective component 60, for example, has a cylindrical connecting cylinder 61 connected to the outer periphery of the tube 40, a cylindrical connecting cylinder 62 connected to the outer periphery of the bellows 50, and a main cylinder 63 arranged between the connecting cylinder 61 and the connecting cylinder 62. The main cylinder 63 is formed to protrude radially outwards more than the outer peripheries of the other parts, namely the connecting cylinders 61 and 62. The main cylinder 63 is formed, for example, to protrude radially outwards more than the connecting cylinders 61 and 62 throughout the entire circumference of the connecting cylinders 61 and 62. The outer peripheral size of the main cylinder 63 is formed, for example, to be larger than the outer peripheral size of the connecting cylinders 61 and 62. The protective component 60 is, for example, a single component in which the connecting cylinder 61, the main cylinder 63 and the connecting cylinder 62 are continuously and integrally formed. The connecting cylinders 61, 62 and the main cylinder 63 of this embodiment are continuously formed throughout the entire circumference, forming a ring-shaped structure with the same starting point and end point. In other words, the connection cylinders 61 and 62 and the main body cylinder 63 of the present embodiment do not form a slit extending in the longitudinal direction of the electric wire 20 .

[0135] For example, the connecting cylindrical portion 61 of the protection member 60 is fitted to the outer periphery of the pipe 40 , and the connecting cylindrical portion 62 is fitted to the outer periphery of the corrugated tube 50 .

[0136] The connecting cylinder 61 is formed, for example, into a cylindrical shape of a size that can be fitted into the outer periphery of the tube 40. The connecting cylinder 61 of this embodiment is formed into a cylindrical shape. On the inner peripheral surface of the end of the connecting cylinder 61, for example, one or more (here, three) lips 61A are formed that protrude toward the outer peripheral surface of the tube 40. Each lip 61A is formed continuously over the entire circumference of the inner peripheral surface of the connecting cylinder 61, forming an annular structure. Each lip 61A is formed, for example, so as to be in close contact with the outer peripheral surface of the tube 40 when the connecting cylinder 61 is fitted into the outer periphery of the tube 40.

[0137] A connecting member 65 is provided on the outer circumferential surface of the connecting cylinder 61. Examples of the connecting member 65 include a resin or metal binding band, a caulking ring, or a belt member. The connecting cylinder 61 is secured to the tube 40 from the outer circumference by the connecting member 65. For example, the connecting cylinder 61 is secured to the tube 40 from the outer circumference by the connecting member 65 until it forms a fluid-tight fit with the tube 40. This prevents water from entering the protective member 60 from between the connecting cylinder 61 and the tube 40.

[0138] The connecting cylinder 62 is formed into a cylindrical shape of a size that can be fitted with the outer periphery of the bellows 50, for example. The connecting cylinder 62 of this embodiment is formed into a cylindrical shape. On the inner peripheral surface of the end of the connecting cylinder 62, for example, one or more (here, three) lips 62A are formed to be locked to the bellows 50. Each lip 62A is formed continuously over the entire circumference of the inner peripheral surface of the connecting cylinder 62, for example, to form an annular structure. Each lip 62A is formed so as to enter the annular recess 52 of the bellows 50 when the connecting cylinder 62 is fitted into the outer periphery of the bellows 50.

[0139] A connecting member 66 is provided on the outer circumferential surface of the connecting tube 62. Examples of the connecting member 66 include a resin or metal binding band, a caulking ring, and a belt member. The connecting tube 62 is secured to the corrugated tube 50 from the outer circumference by the connecting member 66. For example, the connecting tube 62 is secured to the corrugated tube 50 from the outer circumference by the connecting member 66 until it is in fluid-tight contact with the corrugated tube 50. This prevents water from entering the protective member 60 from between the connecting tube 62 and the corrugated tube 50.

[0140] The main body tube portion 63 is, for example, formed integrally with the connecting tube portion 61 at one end and formed integrally with the connecting tube portion 62 at the other end. The main body tube portion 63 is, for example, formed in a cylindrical shape of a size capable of accommodating the electromagnetic wave absorbing component 80. The main body tube portion 63 of this embodiment is formed in a cylindrical shape. The main body tube portion 63 is formed so as to surround the electromagnetic wave absorbing component 80 throughout the entire circumference. The main body tube portion 63 is, for example, configured to surround the electric wires 20 exposed from the tube 40 and the corrugated tube 50, the positioning component 90, the electromagnetic wave absorbing component 80, the fixing component 100, the braided component 110, and the limiting components 120 and 121 throughout the entire circumference. The main body tube portion 63 is, for example, configured to surround the outer periphery of the rivet ring 115 throughout the entire circumference.

[0141] Next, the effects of this embodiment will be described.

[0142] (1) The wiring harness 10 includes: an electric wire 20; a positioning member 90 made of synthetic resin, which is provided on the outer periphery of the electric wire 20; an annular electromagnetic wave absorbing member 80 having a through-hole 81 through which the power supply line 20 passes and fixed to the positioning member 90; and a fixing member 100, which fixes the positioning member 90 to the electric wire 20. The positioning member 90 includes a main body 90A including an insertion portion 91 inserted into the through-hole 81, and a fixing portion 92 protruding from the main body 90A toward the outside of the through-hole 81. The fixing member 100 is formed so as to fasten the electric wire 20 to the fixing portion 92.

[0143] According to this configuration, the insertion portion 91 of the positioning member 90 is inserted into the inner side of the through-hole 81 of the electromagnetic wave absorbing member 80. This allows the synthetic resin positioning member 90 to be sandwiched between the inner circumferential surface of the through-hole 81 and the electrical wire 20. This prevents direct contact between the inner circumferential surface of the through-hole 81 and the outer circumferential surface of the electrical wire 20. Consequently, even when the electromagnetic wave absorbing member 80 vibrates due to, for example, vehicle travel, damage to the electrical wire 20 caused by contact with the edge of the inner circumferential surface of the through-hole 81 can be prevented.

[0144] (2) Furthermore, the positioning member 90 is fixed to the electric wire 20 by the fixing member 100, and the electromagnetic wave absorbing member 80 is fixed to the positioning member 90. Therefore, it is possible to suppress positional displacement of the positioning member 90 relative to the electric wire 20, and it is possible to suppress positional displacement of the electromagnetic wave absorbing member 80 relative to the electric wire 20.

[0145] (3) The positioning member 90 is provided with a protrusion 93, which is provided between the insertion portion 91 and the fixing portion 92 and protrudes from the outer peripheral surface of the main body 90A in a direction intersecting the longitudinal direction of the electric wire 20. By bringing the side surface 82C of the electromagnetic wave absorbing member 80 into contact with the protrusion 93, the electromagnetic wave absorbing member 80 can be easily positioned relative to the positioning member 90. Therefore, the assembly workability of the wire harness 10 can be improved.

[0146] (4) Furthermore, by bringing the side surface 82C of the electromagnetic wave absorbing member 80 into contact with the protrusion 93, the relative movement of the electromagnetic wave absorbing member 80 with respect to the positioning member 90 in the longitudinal direction of the electric wire 20 can be restricted. Thus, positional deviation of the electromagnetic wave absorbing member 80 with respect to the positioning member 90 can be appropriately suppressed.

[0147] (5) The protrusion 93 is formed so that the amount of protrusion from the outer peripheral surface of the main body 90A decreases as it moves from the insertion portion 91 side toward the fixing portion 92 side. According to this structure, the outer peripheral surface of the protrusion 93 is formed as an inclined surface 93C. Therefore, even when the braided component 110 is provided so as to surround the outer periphery of the protrusion 93, damage to the braided component 110 caused by contact with the outer peripheral surface of the protrusion 93 can be appropriately suppressed.

[0148] (6) The positioning member 90 is provided with a protrusion 94 that protrudes in a direction intersecting the axial direction from the outer peripheral surface of the end portion of the main body 90A opposite the fixing portion 92 in the axial direction. By bringing the side surface 82B of the electromagnetic wave absorbing member 80 into contact with the protrusion 94, the electromagnetic wave absorbing member 80 can be easily positioned relative to the positioning member 90. Therefore, the assembly workability of the wire harness 10 can be improved.

[0149] (7) Furthermore, by bringing the side surface 82B of the electromagnetic wave absorbing member 80 into contact with the protrusion 94, the relative movement of the electromagnetic wave absorbing member 80 with respect to the positioning member 90 in the longitudinal direction of the electric wire 20 can be restricted. Thus, positional deviation of the electromagnetic wave absorbing member 80 with respect to the positioning member 90 can be appropriately suppressed.

[0150] (8) The electromagnetic wave absorbing member 80 is fixed to the positioning member 90 using the protrusions 93 and 94 of the positioning member 90. This configuration eliminates the need for providing a component for fixing the electromagnetic wave absorbing member 80 to the positioning member 90 separately from the positioning member 90, thereby reducing the number of components.

[0151] (9) The protrusion 94 is formed so that the amount of protrusion from the outer peripheral surface of the main body 90A decreases as it moves away from the electromagnetic wave absorbing member 80. Furthermore, the outer peripheral surface 94B of the portion of the protrusion 94 that contacts the side surface 82B of the electromagnetic wave absorbing member 80 is flush with the outer peripheral surface 82A of the electromagnetic wave absorbing member 80. With this configuration, the outer peripheral surface 94B of the protrusion 94 is flush with the outer peripheral surface 82A of the electromagnetic wave absorbing member 80 and is tapered so that the amount of protrusion decreases as it moves away from the flush portion. For example, even if the corner of the electromagnetic wave absorbing member 80 is formed into a sharp angle, by tapering the outer peripheral surface 94B of the protrusion 94 that is formed continuously with the outer peripheral surface of the electromagnetic wave absorbing member 80, the corner of the electromagnetic wave absorbing member 80 can be formed into an approximately tapered shape. Thus, even when the knitted component 110 is provided so as to surround the outer periphery of the electromagnetic wave absorbing component 80 and the protrusion 94 , damage to the knitted component 110 caused by contact with the outer peripheral surface 82A of the electromagnetic wave absorbing component 80 and the outer peripheral surface 94B of the protrusion 94 can be appropriately suppressed.

[0152] (10) The restricting members 120 and 121 are formed so as to tighten the braided member 110 from the outside toward the electric wires 20. Therefore, it is possible to suppress the braided member 110 from spreading radially outward from the electric wires 20. This improves the workability when attaching the protective member 60 so as to cover the outer periphery of the braided member 110.

[0153] (11) The restricting member 120 is provided so as to surround the outer periphery of the fixing portion 92 of the positioning member 90. Thus, the restricting member 120 tightens the braided member 110 toward the electric wire 20 and the fixing portion 92. In this case, compared to a case where the braided member 110 is tightened only on the outer periphery of the electric wire 20, the thickness of the object to which the braided member 110 is tightened increases by an amount corresponding to the thickness of the fixing portion 92. This reduces the height difference between the outer periphery 82A of the electromagnetic wave absorbing member 80 and the outer periphery of the restricting member 120. This prevents an increase in the tension applied to the braided member 110 between the portion surrounding the outer periphery 82A of the electromagnetic wave absorbing member 80 and the portion covered by the restricting member 120, thereby preventing a reduction in the elasticity of the braided member 110 in this portion. Consequently, wear of the braided member 110 due to contact with the outer periphery 82A of the electromagnetic wave absorbing member 80 can be suppressed, and damage to the braided member 110 can be prevented.

[0154] (12) The fixing portion 92 is formed so as to extend from the insertion portion 91 toward the corrugated tube 50. In other words, the fixing portion 92 is formed so as to extend from the insertion portion 91 in a direction away from the metal pipe 40. Therefore, for example, interference between the bracket 70 attached to the end of the pipe 40 and the fixing portion 92 can be appropriately suppressed.

[0155] (Other embodiments)

[0156] The above embodiment can be implemented with the following modifications: The above embodiment and the following modifications can be implemented in combination with each other within a range that does not cause technical contradictions.

[0157] For example, you can also Figure 5 As shown, a belt component 125 is provided that is wound around the outer peripheral surface of the braided component 110 surrounding the outer periphery of the caulking ring 115. That is, the belt component 125 may be wound around the outer peripheral surface of the braided component 110 at the end of the braided component 110 toward the corrugated tube 50 and the portion folded back radially outward. The belt component 125 is formed, for example, so as to fasten the braided component 110 from the outside of the braided component 110 toward the tube 40. The belt component 125 is provided, for example, to fasten the braided component 110 radially inward. The belt component 125 is provided, for example, so as to overlap the caulking ring 115 in a direction intersecting the longitudinal direction of the electric wire 20. Thus, the outer periphery of the caulking ring 115 is surrounded by the belt component 125.

[0158] The installation positions of the restriction members 120 and 121 in the above-mentioned embodiment are not particularly limited.

[0159] For example, you can also Figure 6 As shown, the restriction member 120 is provided between the fixing portion 92 and the corrugated tube 50. That is, the restriction member 120 may be provided at a position that does not overlap with the fixing portion 92 in a direction intersecting the longitudinal direction of the electric wire 20.

[0160] In the above embodiment, the restriction members 120 and 121 are formed of the belt member 122 , but the present invention is not limited thereto. For example, a metal belt or a resin binding belt may be used as the restriction members 120 and 121 .

[0161] The restriction member 121 in the above embodiment may be omitted.

[0162] The restriction member 120 in the above embodiment may be omitted.

[0163] In the above embodiment, the fixing member 100 is formed of the belt member 101 , but the present invention is not limited thereto. For example, a metal belt or a resin binding band may be used as the fixing member 100 .

[0164] In the positioning member 90 of the above embodiment, the outer peripheral surface 94B of the portion of the protrusion 94 that contacts the side surface 82B of the electromagnetic wave absorbing member 80 is flush with the outer peripheral surface 82A of the electromagnetic wave absorbing member 80 , but the present invention is not limited thereto.

[0165] For example, you can also Figure 7 As shown, the thickness of the side surface 94A of the protrusion 94 is formed to be smaller than the thickness of the side surface 82B of the electromagnetic wave absorbing member 80. In this case, the side surface 94A faces only a portion of the side surface 82B in the radial direction.

[0166] In the positioning member 90 of the above embodiment, the protrusion 94 is formed so that the amount of radial outward protrusion from the outer peripheral surface of the main body 90A decreases as it moves away from the electromagnetic wave absorbing member 80. However, the shape of the protrusion 94 is not limited thereto.

[0167] For example, you can also Figure 8 As shown, the protrusion amount of the protrusion 94 is formed to be uniform over the entire length of the protrusion 94 in the axial direction of the main body 90A. That is, the formation of the inclined surface 94C of the protrusion 94 may be omitted.

[0168] The protrusion 94 may be omitted from the positioning member 90 of the above embodiment.

[0169] In the positioning member 90 of the above embodiment, the protrusion 93 is formed so that the amount of radial outward protrusion from the outer peripheral surface of the main body 90A decreases from the insertion portion 91 side toward the fixing portion 92. However, the shape of the protrusion 93 is not limited thereto.

[0170] For example, you can also Figure 8As shown, the protrusion amount of the protrusion 93 is formed to be uniform over the entire length of the protrusion 93 in the axial direction of the main body 90A. That is, the formation of the inclined surface 93C of the protrusion 93 may be omitted.

[0171] For example, you can also Figure 9 As shown, the protrusion 93 is omitted from the positioning member 90 .

[0172] In the positioning member 90 of the above embodiment, the main body 90A is formed into a cylindrical shape, but the present invention is not limited thereto. For example, the main body 90A may be formed into a semicircular arc shape in cross section.

[0173] In the above embodiment, the fixing portion 92 is disposed between the insertion portion 91 and the corrugated tube 50 , but the present invention is not limited thereto. For example, the fixing portion 92 may be disposed between the insertion portion 91 and the tube 40 .

[0174] A plurality of fixing portions 92 may be provided in the positioning member 90 of the above embodiment.

[0175] In the above embodiment, the electromagnetic wave absorbing member 80 is fixed to the positioning member 90 using the protrusions 93 and 94 of the positioning member 90. However, the method for fixing the electromagnetic wave absorbing member 80 to the positioning member 90 is not particularly limited. For example, the electromagnetic wave absorbing member 80 may be fixed to the positioning member 90 by tightening the electromagnetic wave absorbing member 80 toward the positioning member 90 using a belt or the like.

[0176] In the above embodiment, the protective member 60 is embodied as a ring-shaped structure, but the present invention is not limited thereto. That is, in the above embodiment, the protective member 60 is embodied as a cylindrical body before the electromagnetic wave absorbing member 80 is arranged inside, but the present invention is not limited thereto.

[0177] For example, you can also Figure 10 As shown in FIG. 1 , the protective member 60 is embodied as a sheet-like structure having a slit 67 extending along the longitudinal direction of the electric wire 20. The protective member 60 of this modified example is formed into a cylindrical shape by, for example, winding a flexible thin sheet around the circumference of the electric wire 20. The protective member 60 has, for example, a first direction ( Figure 10The protective member 60 includes an end portion 68 (in the circumferential direction of the electric wire 20) and an end portion 69 on the opposite side of the end portion 68 in the first direction. The protective member 60 is formed into a cylindrical shape, for example, by overlapping the end portions 68 and 69 in the radial direction of the electromagnetic wave absorbing member 80. For example, by adjusting the overlapping width between the end portions 68 and 69, the inner circumferential dimension of the protective member 60 can be adjusted to match the outer circumferential dimension of the electromagnetic wave absorbing member 80. The protective member 60 has, for example, elasticity that allows it to return from a cylindrical state capable of surrounding the outer circumference of the electromagnetic wave absorbing member 80 to a thin sheet state that does not surround the outer circumference of the electromagnetic wave absorbing member 80.

[0178] The protective member 60 is, for example, Figure 2 The connecting members 65 and 66 shown are fixed to the outer peripheries of the tube 40 and the corrugated tube 50, respectively, to maintain the cylindrical state. As the connecting members 65 and 66, for example, a belt member, a binding band, a caulking ring, etc. can be used.

[0179] Next, according to Figure 11 , the structure of the case where the belt members 65A and 66A are used as the connecting members 65 and 66, respectively, will be described.

[0180] The belt member 65A is formed to fix the longitudinal end of the protection member 60 to the outer peripheral surface of the tube 40, for example. The belt member 66A is formed to fix the longitudinal end of the protection member 60 to the outer peripheral surface of the corrugated tube 50, for example.

[0181] The belt member 65A is wound, for example, over the outer circumference of the longitudinal end portion of the protective member 60 and the outer circumference of the tube 40 exposed from the protective member 60. The belt member 65A is wound continuously, for example, from the outer circumference of the protective member 60 to the outer circumference of the tube 40. The belt member 65A has, for example, an overlapping winding structure. The belt member 65A is wound around the outer circumference of the end portion of the protective member 60, for example, so as to maintain the cylindrical state of the protective member 60.

[0182] The belt member 66A is wound, for example, over the outer circumference of the longitudinal end portion of the protective member 60 and the outer circumference of the corrugated tube 50 exposed from the protective member 60. The belt member 66A is wound continuously, for example, from the outer circumference of the protective member 60 to the outer circumference of the corrugated tube 50. The belt member 66A has, for example, an overlapping winding structure. The belt member 66A is wound around the outer circumference of the end portion of the protective member 60, for example, so as to maintain the cylindrical state of the protective member 60.

[0183] ·You can also Figure 10The protective member 60 shown in FIG. 1 is provided with an adhesive layer or a cohesive layer on one side. For example, an adhesive layer or a cohesive layer may be provided on one side of the end portion 69 of the protective member 60. According to this structure, when the end portion 68 and the end portion 69 of the protective member 60 overlap, the end portion 69 can be adhered to the end portion 68 by the adhesive layer or the cohesive layer. Figure 11 ) in the stage before being fixed, the protection member 60 can be appropriately suppressed from returning to the sheet state.

[0184] As the material of the protective component 60 of the above-mentioned embodiment, for example, a material having better impact resistance and cushioning properties than the tube 40 and the bellows 50 can be used. For example, as the material of the protective component 60, for example, a material having better sound absorption properties than the tube 40 and the bellows 50 can be used. As the material of such a protective component 60, for example, a porous material can be used. As the material of the protective component 60, for example, a foamed resin can be used. The bubble structure in the foamed resin can be a continuous bubble structure or an independent bubble structure. As the material of the protective component 60, for example, polyurethane foam, polyethylene foam, ethylene propylene rubber foam, etc. can be used. By using the materials described above as the material of the protective component 60, the protective component 60 can function appropriately as a cushioning component.

[0185] According to this structure, the protective member 60 as a buffer member can be interposed between the electromagnetic wave absorbing member 80 and its surrounding members. This can suppress the generation of abnormal noise caused by contact between the electromagnetic wave absorbing member 80 and the surrounding members.

[0186] In the above embodiment, the caulking ring 115 is used as a connecting member for electrically securing the end of the braided component 110 to the outer peripheral surface of the tube 40. However, the present invention is not limited to this. For example, a metal band, a resin binding band, a belt member, or the like may be used as the connecting member in place of the caulking ring 115.

[0187] In the above embodiment, the first exterior component is embodied as a metal tube 40, and the second exterior component is embodied as a bellows 50, but this is not limiting. For example, a rigid resin tube, a bellows, or a rubber waterproof cover can be used as the first exterior component. Furthermore, a rigid resin tube, a metal tube, or a rubber waterproof cover can be used as the second exterior component. For example, the first and second exterior components can also be embodied as the same type of exterior components.

[0188] For example, you can also Figure 12As shown, the first exterior component is embodied as a bellows 140, and the second exterior component is embodied as a bellows 50. The bellows 140 is, for example, provided separately from the bellows 50 in the longitudinal direction of the electric wires 20. The bellows 140 is, for example, provided so as to surround the outer periphery of the plurality of electric wires 20 throughout the entire circumference. The bellows 140 is, for example, provided so as to surround a portion of the longitudinal direction of the electric wires 20. The bellows 140 has a corrugated structure in which annular protrusions 141 and annular recesses 142 are alternately and continuously provided along its longitudinal direction. The braided component 110 of this modified example is, for example, formed so as to surround the outer peripheries of the plurality of electric wires 20 collectively within the internal space of the bellows 140. In other words, the bellows 140 is provided so as to surround the outer peripheries of the electric wires 20 and the braided component 110. The protective component 60 of this modified example is, for example, provided so as to be bridged between the outer peripheries of the bellows 140 and the outer peripheries of the bellows 50. For example, the connecting cylindrical portion 61 of the protection member 60 is fitted to the outer periphery of the corrugated tube 140 , and the connecting cylindrical portion 62 is fitted to the outer periphery of the corrugated tube 50 .

[0189] In the above embodiment, the braided component 110 is provided so as to cover the outer periphery of the electromagnetic wave absorbing component 80, but the present invention is not limited thereto. For example, the braided component 110 may be provided to extend through the through-hole 81 of the electromagnetic wave absorbing component 80. In this case, the braided component 110 extends through the through-hole 81, for example, while surrounding the outer periphery of the plurality of electrical wires 20.

[0190] The braided member 110 of the above embodiment may be replaced with another electromagnetic shielding member such as metal foil.

[0191] The knitted component 110 in the above embodiment may be omitted.

[0192] The electric wire 20 in the above embodiment may be changed to a shielded electric wire.

[0193] In the above embodiment, the electromagnetic wave absorbing member 80 is composed only of the magnetic core 82 , but the present invention is not limited thereto. For example, the electromagnetic wave absorbing member 80 may be composed of a housing that includes the magnetic core 82 and the housing that houses the magnetic core 82 .

[0194] The number and installation positions of the electromagnetic wave absorbing members 80 in the above embodiment are not particularly limited. For example, two or more electromagnetic wave absorbing members 80 may be provided with respect to the wire harness 10 .

[0195] In the above embodiment, two wires 20 are housed within the exterior member 30 . However, this is not particularly limiting, and the number of wires 20 can be varied depending on the specifications of the vehicle V. For example, the number of wires 20 housed within the exterior member 30 may be one, or three or more. For example, the exterior member 30 may also include low-voltage wires connecting the low-voltage battery to various low-voltage devices (e.g., lights, car audio, etc.).

[0196] The arrangement relationship between the inverter 11 and the high-voltage battery 12 in the vehicle V is not limited to that in the above-described embodiment, and may be appropriately changed according to the vehicle structure.

[0197] For example, you can also Figure 13 As shown, the wiring harness 10 electrically connects a high-voltage battery 12 disposed substantially entirely on the floor of the vehicle V to an inverter 11 .

[0198] In the above embodiment, the inverter 11 and high-voltage battery 12 are used as the electrical equipment connected by the wiring harness 10, but this is not limiting. For example, wires connecting the inverter 11 to a wheel-driving motor may also be used. In other words, any device that electrically connects electrical equipment mounted on the vehicle V is applicable.

[0199] As shown in the illustrated embodiment, the open end portion of the first exterior member 40 can be spaced apart from the open end portion of the second exterior member 50. The predetermined axial position of the electric wire 20 can be located in the axial gap formed between the open end portions of the first exterior member 40 and the second exterior member 50. The open end portion of the first exterior member 40 can face the side surface 82B of the electromagnetic wave absorbing member 80, while the open end portion of the second exterior member 50 can face the side surface 82C of the electromagnetic wave absorbing member 80.

[0200] The protective member 60 of the illustrated embodiment can be configured as a continuous cylindrical body that connects the open end portion of the first exterior member 40 and the open end portion of the second exterior member 50 so that the open end portion of the first exterior member 40 and the open end portion of the second exterior member 50 are separated by an axial gap therebetween. The protective member 60 of the illustrated embodiment can include: a first cylindrical end portion configured to be mounted on the radially outer surface of the open end portion of the first exterior member 40; a second cylindrical end portion configured to be mounted on the radially outer surface of the open end portion of the second exterior member 50; and a cylindrical middle portion extending between the first cylindrical end portion and the second cylindrical end portion. In one example, the cylindrical middle portion can be configured so that the axial gap formed between the open end portions of the first exterior member 40 and the open end portions of the second exterior member 50 is not exposed to the outside of the wiring harness 10. In the illustrated embodiment, the tubular middle portion of the protective component 60 can be configured to cover the entire electromagnetic wave absorbing component 80 sandwiched between the open end portion of the first outer component 40 and the open end portion of the second outer component 50, as well as the exposed portion of the woven component 110 not covered by the first outer component 40 and the second outer component 50.

[0201] The insertion portion 91 of the positioning member 90 of the embodiment may have a first radius of curvature when the insertion portion 91 of the positioning member 90 is in a first state, not inserted between the electromagnetic wave absorbing member 80 and the electric wire 20, and may have a second radius of curvature different from the first radius of curvature when the insertion portion 91 of the positioning member 90 is in a second state, inserted between the electromagnetic wave absorbing member 80 and the electric wire 20. The insertion portion 91 may be configured, for example, to reversibly elastically deform between the first and second radii of curvature. When the insertion portion 91 is in the second state, the radially inward surface of the insertion portion 91 may press against or be in frictional contact with the radially outward surface of the electric wire 20.

[0202] The fixing portion 92 of the positioning member 90 of the embodiment can have a third radius of curvature when the insertion portion 91 of the positioning member 90 is in a first state, not inserted between the electromagnetic wave absorbing member 80 and the electric wire 20. When the insertion portion 91 of the positioning member 90 is in a second state, inserted between the electromagnetic wave absorbing member 80 and the electric wire 20, it can have a fourth radius of curvature that is the same as or different from the third radius of curvature. The third radius of curvature of the fixing portion 92 can be the same as the first radius of curvature of the insertion portion 91. The fourth radius of curvature of the fixing portion 92 can be the same as or different from the second radius of curvature of the insertion portion 91. When the fixing member 100 is wrapped around the outer surface of the fixing portion 92, which covers the first portion of the outer surface of the electric wire 20, and the second portion of the outer surface of the electric wire 20, excluding the first portion and not covered by the fixing portion 92, the radially inward surface of the fixing portion 92 can press against the radially outward surface of the electric wire 20. In one example, when the fixing member 100 is not wrapped around the outer surface of the fixing portion 92 , the radially inner surface of the fixing portion 92 is in frictional contact with the radially outer surface of the wire 20 , but the radially outer surface of the wire 20 may not be pressed.

[0203] The electromagnetic wave absorbing member 80 of the embodiment is sometimes referred to as an electromagnetic noise filter. The positioning member 90 and the fixing member 100 of the embodiment can function as anchoring elements for the electromagnetic noise filter, and are configured to attach the electromagnetic wave absorbing member 80, for example, coaxially with the electric wire 20, to a predetermined axial position on the electric wire 20.

[0204] The embodiments disclosed herein are to be considered in all respects as illustrative and non-restrictive. The scope of the present invention is defined not by the above description but by the claims, and is intended to encompass all modifications within the meaning and scope equivalent to the claims.
