[0009] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The wire harness of the present disclosure includes: [1] A wire harness main body having an electric wire member and an exterior member covering an outer periphery of the electric wire member; a first path regulating member attached to the outer periphery of the exterior member and regulating a path of the wire harness main body; and an attachment member attached to the outer periphery of the first path regulating member at a part of its longitudinal direction, wherein the first path regulating member has an insertion opening that opens in a direction perpendicular to the longitudinal direction of the first path regulating member and extends over the entire longitudinal direction of the first path regulating member, and the attachment member has a covering portion covering the outer periphery of the first path regulating member, and a filler member that is insertable along the longitudinal direction of the first path regulating member between the insertion openings so as to fill the gap between the covering portion and the exterior member without any gaps and is inserted.
[0010] According to this configuration, the filling member is inserted between the insertion openings so as to be insertable along the length direction of the first path regulating member so as to fill the gap between the covering portion and the exterior member without any gap, so that the covering portion and the first path regulating member are maintained in abutting contact with each other. In this way, rattling between the covering portion and the first path regulating member is suppressed compared to a configuration in which the covering portion is composed of a receiving portion and a lid, the lid is integrally molded with the receiving portion via a thin hinge portion, and the lid is simply locked to the receiving portion by engagement of the claw portion in the closed state. That is, in a configuration having a thin hinge portion and a claw portion, rattling between the receiving portion and the lid occurs at each portion of the hinge portion and the claw portion, and as a result, rattling between the covering portion and the first path regulating member is likely to occur, but this can be avoided. Therefore, rattling between the first path regulating member and the mounting member can be suppressed.
[0011] [2] It is preferable that the filler member be engaged with the insertion opening in the circumferential direction of the first path regulating member to suppress relative rotation of the first path regulating member with respect to the covering portion in the circumferential direction.
[0012] According to this configuration, the interposing member engages with the insertion opening in the circumferential direction of the first path regulating member, thereby suppressing relative rotation in the circumferential direction of the first path regulating member with respect to the covering portion. [3] It is preferable that the filler member is inserted so as to fill the gap between the covering portion and the exterior member over the entire length of the covering portion.
[0013] According to this configuration, the filler member is inserted so as to fill the gap between the covering portion and the exterior member over the entire length of the covering portion without any gaps. This makes it possible to better suppress rattling between the first path-regulating member and the mounting member compared to, for example, a case in which the filler member is inserted only over a portion of the length of the covering portion.
[0014] [4] It is preferable that the covering portion has an engaged portion, and the packing member has an engaging portion that engages with the engaged portion in a direction opposite to the insertion direction of the packing member. According to this configuration, the stuffing member has an engaging portion that engages with the engaged portion of the covering portion in the direction opposite to the insertion direction of the stuffing member, so that the stuffing member in the assembled state is prevented from falling out.
[0015] [5] It is preferable that the engaged portion is a engaged recess recessed into the inner circumferential surface of the covering portion, and the engaging portion is an engaging protrusion that fits into the engaged recess from the radial inside of the covering portion.
[0016] According to this configuration, the engaged portion is an engaged recess recessed from the inner circumferential surface of the covering portion, and the engaging portion is an engaging protrusion that fits into the engaged recess from the radial inside of the covering portion, so that, for example, the engaged portion and the engaging portion can be prevented from protruding radially outward from the covering portion, thereby making it possible to miniaturize the wire harness.
[0017] [6] It is preferable that the covering portion has a receiving portion that covers a portion of the circumference of the first path regulating member, and a cover that is fixed to the receiving portion and that, together with the receiving portion, covers the entire circumference of the first path regulating member.
[0018] According to this configuration, since the covering portion has a receiving portion and a lid fixed to the receiving portion, for example, the covering portion can be easily attached to the first path restricting member. This improves the workability of assembling the wire harness compared to, for example, a case in which the covering portion is a non-deformable cylinder. Note that in a configuration having a receiving portion and a lid, rattling is likely to occur between the receiving portion and the lid, which makes rattling likely to occur between the covering portion and the first path restricting member, but this rattling can be avoided by using the filling member.
[0019] [7] It is preferable that the mounting member is a second path regulating member attached to the outer periphery of the exterior member and regulating the path of the wire harness main body, and the covering portion is provided at an end of the second path regulating member in a longitudinal direction and covers an outer periphery of the end of the first path regulating member in the longitudinal direction.
[0020] According to this configuration, the covering portion is provided at the end of the second path regulating member in the longitudinal direction and covers the outer periphery of the end of the first path regulating member in the longitudinal direction, so that the first path regulating member and the second path regulating member are connected in the longitudinal direction. Thus, the path of the wire harness main body is continuously regulated by the first path regulating member and the second path regulating member.
[0021] [8] It is preferable that the first path regulating member regulates the path of a straight portion, which is a straight portion in the path of the wire harness main body, and the second path regulating member regulates the path of a bent portion, which is a bent portion in the path of the wire harness main body.
[0022] According to this configuration, the path of the straight portion is restricted by the first path restricting member, and the path of the bent portion is restricted by the second path restricting member, thereby continuously preventing the paths of the straight portion and the bent portion of the wire harness from deviating from the desired paths.
[0023] [Details of the embodiment of the present disclosure] Specific examples of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, some of the configuration may be exaggerated or simplified. In addition, the dimensional ratio of each part may differ in each drawing. In this specification, "parallel" and "orthogonal" do not only mean strictly parallel or orthogonal, but also include roughly parallel or orthogonal within the range in which the action and effect of this embodiment is achieved. Note that the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
[0024] (Overall configuration of the wire harness 10) A wire harness 10 shown in FIG. 1 is mounted on a vehicle V such as a hybrid vehicle or an electric vehicle. The wire harness 10 electrically connects two or more in-vehicle devices to each other. The in-vehicle devices are electrical devices mounted on the vehicle V. The wire harness 10 electrically connects, for example, an inverter M1 installed at the front of the vehicle V and a high-voltage battery M2 installed behind the inverter M1 on the vehicle V. The wire harness 10 is formed in an elongated shape so as to extend, for example, in the front-rear direction of the vehicle V. The wire harness 10 is routed in the vehicle V so that, for example, a middle portion of the length of the wire harness 10 passes outside the passenger compartment, such as under the floor of the vehicle V.
[0025] The inverter M1 is connected to, for example, a wheel drive motor (not shown) that serves as a power source for driving the vehicle. The inverter M1 generates AC power from DC power of a high-voltage battery M2 and supplies the AC power to the motor. The high-voltage battery M2 is, for example, a battery capable of supplying a voltage of several hundred volts.
[0026] The wire harness 10 has a wire harness main body 11. The wire harness main body 11 has an electric wire member 20 and a cylindrical exterior member 30 that covers the outer periphery of the electric wire member 20. The wire harness 10 has connectors C1, C2 attached to both ends of the electric wire member 20. One end in the length direction of the electric wire member 20 is connected to the inverter M1 via the connector C1, and the other end in the length direction of the electric wire member 20 is connected to the high-voltage battery M2 via the connector C2.
[0027] 2 and 3, the wire harness 10 has a first path regulating member 40 attached to the outer periphery of the exterior member 30, and a second path regulating member 60 as an attachment member attached to the outer periphery of the exterior member 30. The first path regulating member 40 and the second path regulating member 60 regulate the route along which the wire harness main body 11 is routed. Note that the first path regulating member 40 and the second path regulating member 60 are not shown in FIG.
[0028] (Configuration of the electric wire member 20) As shown in Figures 4 and 7, the electric wire member 20 may be, for example, one or more electric wires, and in this embodiment, it has two electric wires 21 and a braided member 25 that collectively surrounds the outer periphery of the multiple electric wires 21.
[0029] As shown in Fig. 7, each electric wire 21 is a covered electric wire having a conductive core wire 22 and an insulating covering 23 that surrounds the outer periphery of the core wire 22 and has insulating properties. Each electric wire 21 is, for example, a high-tension electric wire that can handle high voltage and large current. Each electric wire 21 may be, for example, a non-shielded electric wire that does not have an electromagnetic shield structure itself, or a shielded electric wire that has an electromagnetic shield structure itself. Each electric wire 21 in this embodiment is a non-shielded electric wire.
[0030] The core wire 22 may be, for example, a stranded wire made of a plurality of metal wires stranded together, or a single core wire made of a single conductor. The single core wire may be, for example, a columnar conductor made of a single metal rod having a solid interior structure, or a tubular conductor having a hollow interior structure. The core wire 22 may be a combination of a stranded wire, a columnar conductor, and a tubular conductor. The material of the core wire 22 may be, for example, a copper-based or aluminum-based metal material.
[0031] The insulating coating 23, for example, covers the entire outer circumferential surface of the core wire 22. The insulating coating 23 is made of, for example, a resin material having insulating properties. The cross-sectional shape of each electric wire 21 cut by a plane perpendicular to the length direction of each electric wire 21, that is, the transverse cross-sectional shape of each electric wire 21, can be formed into any shape. The transverse cross-sectional shape of each electric wire 21 is formed into, for example, a circular shape, a semicircular shape, a polygonal shape, a square shape, a flat shape, or the like. The transverse cross-sectional shape of each electric wire 21 in this embodiment is formed into a circular shape.
[0032] The braided member 25 has, for example, a cylindrical shape that collectively surrounds the outer circumference of the plurality of electric wires 21. As the braided member 25, for example, a braided wire in which a plurality of metal wires are woven, or a braided wire in which metal wires and resin wires are combined and woven, can be used. As the material of the metal wires, for example, a copper-based or aluminum-based metal material can be used. Although not shown in the drawings, both ends of the braided member 25 in the length direction are earthed, for example, by connectors C1 and C2 (see FIG. 1).
[0033] (Configuration of exterior member 30) As shown in Fig. 4, the exterior member 30 has a tubular shape surrounding the outer periphery of the electric wire member 20 over the entire circumferential direction. The exterior member 30 of this embodiment is formed in a cylindrical shape. For example, the exterior member 30 has a peripheral wall formed continuously over the entire circumferential direction of the exterior member 30. For example, the exterior member 30 seals the inside of the exterior member 30 over the entire circumferential direction. The exterior member 30 has a function of protecting the electric wire member 20 from flying objects and water droplets, for example.
[0034] The exterior member 30 is, for example, flexible and easily bendable. Examples of the flexible exterior member 30 include, for example, a resin corrugated tube and a rubber waterproof cover. The exterior member 30 of this embodiment is a resin corrugated tube having a bellows shape in which the diameters are repeatedly increased and decreased in the length direction of the exterior member 30. That is, the exterior member 30 of this embodiment has a bellows structure in which large diameter parts 31 and small diameter parts 32 having a diameter smaller than the large diameter parts 31 are alternately provided along the length direction of the exterior member 30. Each of the large diameter parts 31 and the small diameter parts 32 is, for example, an annular shape that goes around once along the circumferential direction of the exterior member 30. As the material of the exterior member 30, for example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin can be used. In addition, in Figs. 1 to 3, the exterior member 30 is illustrated in a simplified form in order to simplify the drawings.
[0035] (Configuration of the first path regulating member 40 and the second path regulating member 60) As shown in Fig. 2 and Fig. 3, each of the first path regulating member 40 and the second path regulating member 60 holds the exterior member 30. Each of the first path regulating member 40 and the second path regulating member 60 is, for example, harder than the exterior member 30. Each of the first path regulating member 40 and the second path regulating member 60 has a hardness that makes it difficult to bend in a direction perpendicular to the length direction of the wire harness main body 11 compared to the exterior member 30. As a result, each of the first path regulating member 40 and the second path regulating member 60 regulates the path of the wire harness main body 11. For example, each of the first path regulating member 40 and the second path regulating member 60 assists the exterior member 30 so that the wire harness main body 11 does not bend due to its own weight or the like and deviate from a desired path.
[0036] As shown in FIG. 2, the first path regulating member 40 is provided partially in the length direction of the wire harness main body 11. The first path regulating member 40 is attached to the outer periphery of the exterior member 30, for example, at a straight portion 11A that is a straight portion of the path of the wire harness main body 11. The first path regulating member 40 regulates the path of the wire harness main body 11 at the straight portion 11A. Here, the straight portion 11A is a portion where the path of the wire harness main body 11 extends linearly in one direction. Note that one or more first path regulating members 40 are provided depending on the path of the wire harness main body 11.
[0037] The second path regulating member 60 is provided partially in the length direction of the wire harness main body 11. The second path regulating member 60 is attached to the outer periphery of the exterior member 30 at, for example, a bent portion 11B which is a bent portion of the path of the wire harness main body 11. The second path regulating member 60 regulates the path of the wire harness main body 11 at the bent portion 11B. Here, the bent portion 11B is a portion where the path of the wire harness main body 11 is bent so as to deviate from a straight line. Note that one or more second path regulating members 60 are provided depending on the path of the wire harness main body 11.
[0038] (Configuration of the first path regulating member 40) As shown in FIG. 7, the first path regulating member 40 covers a part of the outer periphery of the exterior member 30 in the circumferential direction of the exterior member 30. The first path regulating member 40 has a shape that covers the outer periphery of the exterior member 30 in a part of the circumferential direction of the exterior member 30. The cross-sectional shape of the first path regulating member 40 is generally C-shaped. The first path regulating member 40 covers, for example, a range larger than half of the outer periphery of the exterior member 30. That is, the first path regulating member 40 covers, for example, a range larger than half of the entire circumferential direction of the exterior member 30 in the outer periphery of the exterior member 30. As shown in FIG. 2, the first path regulating member 40 extends along the length direction of the exterior member 30 in the straight portion 11A. The first path regulating member 40 is formed, for example, in a shape that extends linearly in one direction. The cross-sectional shape of the first path regulating member 40 is, for example, uniform over the entire length of the first path regulating member 40 in the length direction.
[0039] The first path regulating member 40 is made of, for example, metal or resin. The first path regulating member 40 of this embodiment is made of resin. As the material of the first path regulating member 40, for example, synthetic resin such as polypropylene, polyamide, polyacetal, etc. can be used. The first path regulating member 40 can be manufactured by a well-known manufacturing method such as extrusion molding or injection molding. In this embodiment, the first path regulating member 40 is an extrusion molded product manufactured by extrusion molding. Therefore, the first path regulating member 40 can be easily manufactured by using an extrusion molding machine that extrudes the raw material of the first path regulating member 40 in the length direction. In addition, a single extrusion molding machine can be used to manufacture multiple types of first path regulating members 40 with different length dimensions. For example, a cutting machine can be used to cut the base material of the first path regulating member 40 formed by a single extrusion molding machine at any length to manufacture multiple types of first path regulating members 40 with different length dimensions.
[0040] The first path regulating member 40 has an insertion opening 40X that opens in a direction perpendicular to the length direction of the first path regulating member 40. The insertion opening 40X extends over the entire length direction of the first path regulating member 40. The first path regulating member 40 has a first end 41 and a second end 42 that are both ends of the first path regulating member 40 in the circumferential direction and form the insertion opening 40X. The first path regulating member 40 has a connecting portion 43 that connects the first end 41 and the second end 42. In other words, the first path regulating member 40 has the connecting portion 43 formed so as to cover a part of the circumferential direction of the exterior member 30, the first end 41 and the second end 42 provided at both ends of the connecting portion 43, and the insertion opening 40X formed by the first end 41 and the second end 42.
[0041] 7, the connecting portion 43 constitutes a main portion of the first path regulating member 40. The radial thickness of the connecting portion 43 is, for example, uniform in the circumferential direction of the first path regulating member 40. The cross-sectional shape of the connecting portion 43 is, for example, formed into a shape that follows the outer surface of the exterior member 30. The cross-sectional shapes of the first end portion 41, the second end portion 42, and the connecting portion 43 are, for example, formed into an arc shape.
[0042] The first end 41 and the second end 42 are provided on opposite sides of the first path regulating member 40 in the circumferential direction. The first end 41 and the second end 42 are provided apart from each other in the circumferential direction of the first path regulating member 40, sandwiching the insertion opening 40X therebetween. In other words, a gap between the first end 41 and the second end 42 in the circumferential direction of the first path regulating member 40 is configured as the insertion opening 40X. In this manner, the first path regulating member 40 is formed in a C-shape having the insertion opening 40X at a portion of the circumferential direction of the first path regulating member 40.
[0043] The cross-sectional shape of the tip of the first end portion 41 and the second end portion 42 is formed into a curved shape. In this embodiment, the cross-sectional shape of the tip of the first end portion 41 and the second end portion 42 is formed into an arc shape.
[0044] The first path regulating member 40 has a protruding portion 45 protruding from the inner surface of the first end portion 41 and a protruding portion 46 protruding from the inner surface of the second end portion 42. Each of the protruding portions 45, 46 protrudes toward the exterior member 30 inserted inside the first path regulating member 40 and contacts the outer surface of the exterior member 30. Each of the protruding portions 45, 46 contacts the outer surface of the large diameter portion 31 of the exterior member 30. The protruding portion 45 protrudes, for example, from the inner surface of the tip of the first end portion 41. The protruding portion 46 protrudes, for example, from the inner surface of the tip of the second end portion 42. The cross-sectional shape of each of the protruding portions 45, 46 is formed, for example, in a curved shape. The cross-sectional shape of each of the protruding portions 45, 46 in this embodiment is formed in an arc shape.
[0045] 3, each of the protrusions 45, 46 extends in the length direction of the first path regulating member 40. Each of the protrusions 45, 46 extends, for example, over the entire length of the first path regulating member 40 in the length direction.
[0046] The protruding portions 45, 46 press the exterior member 30 from the outside of the exterior member 30. The exterior member 30 is elastically sandwiched between the protruding portions 45, 46, and the connecting portion 43. This makes the connection of the first path regulating member 40 to the exterior member 30 strong.
[0047] As shown in FIG. 7, the opening width of the insertion opening 40X, that is, the shortest distance between the first end 41 and the second end 42, is smaller than the outer diameter of the exterior member 30. The opening width of the insertion opening 40X becomes larger as the first path regulating member 40 elastically deforms. For example, the opening width of the insertion opening 40X becomes larger as the exterior member 30 is inserted into the insertion opening 40X from a direction perpendicular to the length direction of the first path regulating member 40. When the exterior member 30 is inserted into the first path regulating member 40, the first path regulating member 40 elastically returns to its original shape. As a result, the opening width of the insertion opening 40X becomes smaller than the outer diameter of the exterior member 30, and the first path regulating member 40 is attached to the outer periphery of the exterior member 30.
[0048] (Configuration of the second path regulating member 60) 2, the second path regulating member 60 is attached to the outer periphery of a portion of the first path regulating member 40 in the longitudinal direction. The second path regulating member 60 is attached to the outer periphery of an end portion of the first path regulating member 40 in the longitudinal direction. The second path regulating member 60 is also attached to the outer periphery of the exterior member 30 at the bent portion 11B. The second path regulating member 60 extends along the longitudinal direction of the exterior member 30 at the bent portion 11B. The second path regulating member 60 is bent, for example, to follow the shape of the bent portion 11B.
[0049] The second path regulating member 60 includes a second path regulating body 61 , a lid 62 , and a filler member 63 . The second path regulating body 61, the lid 62, and the packing member 63 constituting the second path regulating member 60 are each made of, for example, metal or resin. In this embodiment, the second path regulating body 61, the lid 62, and the packing member 63 are made of resin. As materials for the second path regulating body 61, the lid 62, and the packing member 63, for example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used. The second path regulating body 61, the lid 62, and the packing member 63 can be manufactured by a well-known manufacturing method such as injection molding.
[0050] The second path regulating body 61 has a main body portion 64 and a receiving portion 65. In this embodiment, the receiving portion 65 and the lid 62 configure a covering portion . The main body portion 64 covers a part of the outer periphery of the exterior member 30 in the circumferential direction of the exterior member 30. The main body portion 64 has a shape that covers the outer periphery of the exterior member 30 in a part of the circumferential direction of the exterior member 30. The cross-sectional shape of the main body portion 64 is a semi-cylindrical shape as a whole. The main body portion 64 covers half of the outer periphery of the exterior member 30. As shown in FIG. 2, the main body portion 64 extends along the length direction of the exterior member 30 at the bent portion 11B. The main body portion 64 is bent along the shape of the bent portion 11B.
[0051] The receiving portion 65 is provided at the end of the second path regulating member 60 in the length direction, which is also the end of the main body portion 64 in the length direction. The receiving portion 65 covers a part of the circumferential direction of the first path regulating member 40 among the outer periphery of the first path regulating member 40. The receiving portion 65 covers a part of the circumferential direction at the end of the length direction of the first path regulating member 40. The receiving portion 65 is shaped to cover the outer periphery of the first path regulating member 40 in a part of the circumferential direction of the first path regulating member 40. The cross-sectional shape of the receiving portion 65 is a semi-cylindrical shape as a whole. The receiving portion 65 is shaped as a semi-cylindrical shape with a diameter larger than that of the main body portion 64. The receiving portion 65 covers half of the outer periphery of the first path regulating member 40.
[0052] As shown in Figs. 5 to 7, the receiving portion 65 has a rail portion 66 extending along the length direction of the receiving portion 65 in the length direction of the second path regulating member 60. The rail portion 66 is a groove having a shape recessed from the outer periphery of the receiving portion 65. The rail portion 66 in this embodiment is not inclined with respect to the length direction of the receiving portion 65, but extends parallel to the length direction of the receiving portion 65. The rail portion 66 is provided near both ends in the circumferential direction of the receiving portion 65. The rail portion 66 is provided over the entire length direction of the receiving portion 65. In other words, the rail portion 66 is open at both ends in the length direction of the receiving portion 65. The rail portion 66 has an engagement protrusion 67. As shown in Fig. 5, two engagement protrusions 67 are provided in the length direction of the rail portion 66. The engagement protrusions 67 are provided in the rail portion 66 near the ends in the length direction of the rail portion 66. The engagement protrusions 67 protrude from the bottom of the rail portion 66 to the radial outside of the receiving portion 65. The engagement protrusion 67 has a spherical shape. More specifically, the engagement protrusion 67 has a shape in which less than half of a sphere is cut off along one flat surface.
[0053] The lid 62 covers the entire circumference of the first path regulating member 40 together with the receiving portion 65. That is, the covering portion 70 constituted by the receiving portion 65 and the lid 62 covers the entire circumference of the first path regulating member 40. More specifically, the lid 62 covers the entire circumferential direction along the outer periphery of the first path regulating member 40 together with the receiving portion 65. The lid 62 of this embodiment covers a part of the outer periphery of the first path regulating member 40 and a part exposed from the insertion opening 40X on the outer periphery of the exterior member 30. The cross-sectional shape of the lid 62 is a semi-cylindrical shape as a whole. The lid 62 has a semi-cylindrical shape with the same diameter as the diameter of the receiving portion 65. The lid 62 covers a part of the circumferential direction along the outer periphery of the first path regulating member 40 that is not covered by the receiving portion 65, and covers half of the circumferential direction along the outer periphery of the first path regulating member 40.
[0054] 4 to 7, the lid 62 has a slide portion 68. The slide portion 68 is capable of sliding along the rail portion 66 while engaging with the rail portion 66 so that the lid 62 does not separate from the receiving portion 65.
[0055] Specifically, as shown in FIG. 7, first, at both ends in the circumferential direction of the lid 62, there are provided extension parts 69 that protrude radially outward of the lid 62, are further bent, and extend to positions facing the rail parts 66. Then, at the tip of the extension part 69, there is provided a slide part 68 that protrudes radially inward of the lid 62 and fits into the rail parts 66. As shown in FIG. 5 and FIG. 6, the slide part 68 extends along the length of the lid 62. The lid 62 is attached so that the slide part 68 faces the receiving part 65 by being fitted and engaged with the rail parts 66 and sliding along the rail parts 66, and the first path regulating member 40 is sandwiched between the receiving part 65 and the lid 62. That is, the receiving part 65 and the lid 62 sandwich the first path regulating member 40 in a state in which the slide part 68 is fitted and engaged with the rail parts 66.
[0056] The slide portion 68 is disposed between the engagement protrusions 67 when the lid 62 is attached to the receiving portion 65. In other words, the engagement protrusions 67 are provided on both sides of the slide portion 68 when the lid 62 is attached to the receiving portion 65. Here, the engagement protrusions 67 allow the slide portion 68, which is fitted and engaged with the rail portion 66, to move. That is, the engagement protrusions 67 protrude to an extent that the slide portion 68 can overcome when the lid 62 is attached to the receiving portion 65 by, for example, slightly bending the lid 62. In addition, the engagement protrusions 67 engage with the slide portion 68 in a direction in which the lid 62 is removed from the state in which the lid 62 is attached to the receiving portion 65, thereby suppressing the lid 62 from falling off from the receiving portion 65. That is, the engagement protrusions 67 engage with the slide portion 68 to an extent that the attached lid 62 does not slide along the length direction of the receiving portion 65 even when a small force such as vibration is applied to the second path regulating member 60.
[0057] 3, 5 and 6, the lid 62 has an engaged protrusion 71 as an engaged portion. The engaged protrusion 71 is provided in a protruding manner from the outer peripheral surface of the lid 62. The engaged protrusion 71 is provided in the circumferential center of the lid 62. The engaged protrusion 71 is provided at an end portion in the longitudinal direction of the lid 62. The engaged protrusion 71 is provided so that its height gradually increases from the end portion in the longitudinal direction of the lid 62 toward the center of the lid 62 in the longitudinal direction.
[0058] As shown in FIG. 7, the filler member 63 is insertable along the length direction of the first path regulating member 40 so as to fill the gap between the covering portion 70 and the exterior member 30 between the insertion openings 40X without any gaps.
[0059] Specifically, the filler member 63 is shaped to fill the gap between the covering portion 70 and the exterior member 30 at the insertion opening 40X without any gap, and has an arc shape. The filler member 63 is sandwiched between the covering portion 70 and the exterior member 30. In other words, the filler member 63 is press-fitted between the covering portion 70 and the exterior member 30. As shown in FIG. 6, the filler member 63 of this embodiment is inserted between the covering portion 70 and the exterior member 30 from the side where the first path regulating member 40 is arranged and where the main body portion 64 of the second path regulating member 60 is not arranged. The receiving portion 65 and the lid 62 may not be able to completely sandwich the first path regulating member 40 due to the problem of the overall dimensional accuracy and the problem of the dimensional accuracy between the rail portion 66 and the slide portion 68, and the first path regulating member 40 may rattle relative to the covering portion 70. Even in such a case, the gap between the covering portion 70 and the exterior member 30 is filled without any gaps by the packing member 63, so that the covering portion 70 and the first path regulating member 40 are maintained in contact with each other. That is, the packing member 63 is inserted between the covering portion 70 and the exterior member 30 so as to prevent the first path regulating member 40 from rattling relative to the covering portion 70. The packing member 63 of this embodiment is inserted between the lid 62 and the exterior member 30, so that the first path regulating member 40 is pressed into contact with the receiving portion 65 via the exterior member 30.
[0060] The packing member 63 is engageable with the insertion opening 40X in the circumferential direction of the first path regulating member 40. The packing member 63 is engageable with the insertion opening 40X on both sides in the circumferential direction of the first path regulating member 40. The packing member 63 suppresses relative rotation of the first path regulating member 40 with respect to the covering portion 70 in the circumferential direction by engaging with the insertion opening 40X.
[0061] The length of the stuffing member 63 is set to be the same as the length of the lid 62. As shown in Fig. 6, the stuffing member 63 is inserted so as to fill the gap between the covering portion 70 and the exterior member 30 over the entire length of the covering portion 70 without leaving any gaps.
[0062] As shown in FIG. 6, the stuffing member 63 has an engaging protrusion 72 as an engaging portion that engages with the engaged protrusion 71 in the opposite direction to the insertion direction of the stuffing member 63. In detail, the stuffing member 63 has an extending portion 73 that extends to the radial outside of the covering portion 70 and a bent extension portion 74 that bends and extends from the tip of the extending portion 73 when inserted between the covering portion 70 and the exterior member 30. The engaging protrusion 72 is provided at the tip of the bent extension portion 74. The engaging protrusion 72 is provided to protrude from the bent extension portion 74 toward the outer circumferential surface side of the lid 62. The engaging protrusion 72 is provided so that its height gradually increases toward the side approaching the extending portion 73. When the stuffing member 63 is inserted between the covering portion 70 and the exterior member 30, the bent extension portion 74 bends, so that the engaging protrusion 72 can overcome the engaged protrusion 71, and in the overcome state, engages with the engaged protrusion 71 in the opposite direction to the insertion direction of the stuffing member 63. This prevents the interposing member 63 from falling out.
[0063] As shown in FIG. 2, the wire harness 10 has a slide restricting member 75 that restricts the sliding movement of the first path restricting member 40 in the length direction of the exterior member 30. The wire harness 10 has a slide restricting member 76 that restricts the sliding movement of the second path restricting member 60 in the length direction of the exterior member 30. As the slide restricting members 75 and 76, for example, a resin or metal cable tie, a crimping ring, or an adhesive tape can be used. The slide restricting members 75 and 76 in this embodiment are adhesive tapes. The slide restricting member 75 is wrapped around an end of the first path restricting member 40 on the side not connected to the second path restricting member 60 and the exterior member 30. The slide restricting member 76 is wrapped around an end of the second path restricting member 60 on the side not connected to the first path restricting member 40 and the exterior member 30.
[0064] Next, the operation of this embodiment will be described. The outer periphery of the first path regulating member 40 is covered by the covering portion 70 of the second path regulating member 60. The filler member 63 is inserted without any gap between the covering portion 70 and the exterior member 30 between the insertion openings 40X of the first path regulating member 40. This maintains the first path regulating member 40 and the second path regulating member 60 in a connected state. Therefore, the path of the wire harness main body 11 is continuously regulated.
[0065] Next, the effects of the above embodiment will be described below. (1) The second path regulating member 60 has a filler member 63 that is insertable along the length direction of the first path regulating member 40 so as to fill the gap between the covering portion 70 and the exterior member 30 between the insertion openings 40X. Thus, the covering portion 70 and the first path regulating member 40 are maintained in contact with each other. In this way, rattling between the covering portion 70 and the first path regulating member 40 is suppressed compared to a configuration in which, for example, the lid 62 is integrally molded with the receiving portion 65 via a thin hinge portion, and the lid 62 is simply locked to the receiving portion 65 by engagement of the claw portion in the closed state. That is, in a configuration having a thin hinge portion and a claw portion, rattling between the receiving portion 65 and the lid 62 occurs at each portion of the hinge portion and the claw portion, and as a result, rattling between the covering portion 70 and the first path regulating member 40 is likely to occur, but this can be avoided. In addition, in the configuration in which the receiving portion 65 and the lid 62 are fixed by the rail portion 66 and the slide portion 68 as in this embodiment, rattling between the covering portion 70 and the first path regulating member 40 can be prevented even without the filler member 63, but rattling can be further suppressed by the filler member 63. Therefore, rattling between the first path regulating member 40 and the second path regulating member 60 can be suppressed. As a result, for example, damage to the attachment portion between the first path regulating member 40 and the second path regulating member 60 can be suppressed, and the path of the wire harness main body 11 can be stably regulated.
[0066] (2) The interposing members 63 engage with the insertion openings 40X in the circumferential direction of the first path regulating member 40, thereby restricting relative rotation of the first path regulating member 40 with respect to the covering portion 70 in the circumferential direction. (3) The filler member 63 is inserted so as to fill the gap between the covering portion 70 and the exterior member 30 over the entire length of the covering portion 70. Therefore, rattling between the first path regulating member 40 and the second path regulating member 60 can be more effectively suppressed than when, for example, the filler member 63 is inserted only partially over the length of the covering portion 70.
[0067] (4) The stuffing member 63 has the engaging convex portion 72 that engages with the engaged convex portion 71 of the covering portion 70 in the direction opposite to the insertion direction of the stuffing member 63, so that the stuffing member 63 in the assembled state is prevented from falling out.
[0068] (5) Since the covering portion 70 has the receiving portion 65 and the lid 62 fixed to the receiving portion 65, for example, the covering portion 70 can be easily attached to the first path regulating member 40. This improves the ease of assembly of the wire harness 10, for example, compared to a case in which the covering portion 70 is an undeformable cylindrical shape. Note that in a configuration having the receiving portion 65 and the lid 62, rattling is likely to occur between the receiving portion 65 and the lid 62, which in turn causes rattling between the covering portion 70 and the first path regulating member 40; however, this rattling can be prevented by the filling member 63.
[0069] (6) The attachment member attached to the first path-regulating member 40 is the second path-regulating member 60 that is attached to the outer periphery of the exterior member 30 and regulates the path of the wire harness main body 11. The covering portion 70 is provided at an end of the second path-regulating member 60 in the longitudinal direction and covers the outer periphery of the end of the first path-regulating member 40 in the longitudinal direction, so that the first path-regulating member 40 and the second path-regulating member 60 are connected in the longitudinal direction. Thus, the path of the wire harness main body 11 is continuously regulated by the first path-regulating member 40 and the second path-regulating member 60.
[0070] (7) The path of the straight portion 11A of the wire harness main body 11 is restricted by the first path restricting member 40, and the path of the bent portion 11B of the wire harness main body 11 is restricted by the second path restricting member 60. This continuously prevents the paths of the straight portion 11A and the bent portion 11B of the wire harness main body 11 from deviating from the desired paths.
[0071] (Other embodiments) The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.
[0072] The engaged protrusions 71 as the engaged portion and the engaging protrusions 72 as the engaging portion in the above embodiment may be changed to an engaged portion and an engaging portion having a different configuration. For example, as shown in FIG. 8 and FIG. 9, the engaging recess 80 may be used as the engaged portion, and the engaging protrusion 81 may be used as the engaging portion that engages with the engaged recess 80. The engaged recess 80 is recessed from the inner peripheral surface of the lid 62. In this example, the engaged recess 80 penetrates from the inner peripheral surface of the lid 62 to the outer peripheral surface of the lid 62. The engaging protrusion 81 is provided on the packing member 63 and is configured to fit into the engaged recess 80 from the radial inside of the lid 62. The engaging protrusion 81 is provided near the end of the packing member 63 in the length direction. The engaging protrusion 81 is provided so that the height gradually decreases from the end of the packing member 63 in the length direction toward the center of the packing member 63 in the length direction. As shown in FIG. 9, when the packing member 63 is inserted between the covering portion 70 and the exterior member 30, the engaging protrusion 81 engages with the engaged recess 80 in the opposite direction to the insertion direction of the packing member 63. This prevents the packing member 63 from falling off.
[0073] In this way, for example, it is possible to prevent the engaged portion and the engaging portion from protruding radially outward from the covering portion 70. Therefore, it is possible to reduce the size of the wire harness 10. In addition, in the above embodiment, the covering portion 70 has an engaged portion and the packing member 63 has an engaging portion, but the covering portion 70 may not have an engaged portion and the packing member 63 may not have an engaging portion.
[0074] In the above embodiment, the packing member 63 engages with the insertion opening 40X in the circumferential direction of the first path regulating member 40, but this is not limited to this and the packing member 63 may be configured so as not to engage with the insertion opening 40X, i.e., may be changed in size so as not to come into contact with the insertion opening 40X.
[0075] In the above embodiment, the stuffing member 63 is inserted between the covering portion 70 and the exterior member 30 over the entire length of the covering portion 70, but this is not limited thereto. For example, the stuffing member 63 may be inserted only over a portion of the covering portion 70 in the length direction.
[0076] In the above embodiment, the covering portion 70 has a configuration including the receiving portion 65 and the lid 62, but this is not limited thereto, and for example, the covering portion 70 may be changed to a configuration in which it is cylindrical and cannot be disassembled or deformed. Also, the receiving portion 65 and the lid 62 may be integrally molded with the receiving portion 65 via a thin hinge portion, and the lid 62 may be locked to the receiving portion 65 by engagement of the claw portion in the closed state.
[0077] In the above embodiment, the rail portion 66 has two engagement protrusions 67, but this is not limited to this. For example, the rail portion 66 may have only one engagement protrusion 67, or may have no engagement protrusions 67 at all.
[0078] In the above embodiment, the rail portion 66 is provided over the entire length of the receiving portion 65, but this is not limited thereto, and the rail portion 66 may not be provided to either end of the receiving portion 65 in the length direction. In other words, the rail portion 66 may be open only at one end of the receiving portion 65 in the length direction, and not open at the other end of the receiving portion 65 in the length direction.
[0079] The second path regulating member 60 in the above embodiment is formed to regulate the path of the bent portion 11B of the wire harness main body 11, but is not limited thereto. For example, the second path regulating member 60 may be changed to a shape that regulates the path of the straight portion 11A of the wire harness main body 11. In this case, for example, the bent shape of the main body portion 64 of the second path regulating member 60 is changed to a shape that extends linearly.
[0080] In the above embodiment, the attachment member attached to the first path regulating member 40 is embodied as the second path regulating member 60, but is not limited thereto. For example, the attachment member may be embodied as a vehicle attachment member for attaching the first path regulating member 40 to the vehicle V.
[0081] The structure of the first path regulating member 40 in the above embodiment can be modified as appropriate. For example, as long as the first path regulating member 40 has an insertion opening 40X and has a structure that allows it to be attached to the outer periphery of the exterior member 30, other structures are not particularly limited.
[0082] The protrusion 45 of the above embodiment may be provided at a position farther from the insertion opening 40X than the tip of the first end 41 in the circumferential direction of the first path regulating member 40. The protrusion 46 in the above embodiment may be provided at a position farther from the insertion opening 40X than the tip of the second end 42 in the circumferential direction of the first path regulating member 40.
[0083] The protruding portions 45 and 46 in the above embodiment may be provided partially in the length direction of the first path regulating member 40 . At least one of the protruding portions 45, 46 in the above embodiment may be omitted.
[0084] In the first path control member 40 of the above embodiment, the radial thickness of the connecting portion 43 may be configured to vary in the circumferential direction. The shape of the connecting portion 43 of the first path regulating member 40 in the above embodiment is not limited to a circular arc shape, but may be changed to, for example, an elliptical arc shape or a U-shape.
[0085] In the above embodiment, the first path regulating member 40 and the second path regulating member 60 are harder than the exterior member 30, but the present invention is not limited to this and may have a hardness equal to or less than that of the exterior member 30. In other words, the first path regulating member 40 and the second path regulating member 60 may act to make the wire harness main body 11 less likely to bend than the wire harness main body 11 in a state in which the first path regulating member 40 and the second path regulating member 60 are not attached.
[0086] The exterior member 30 in the above embodiment may be, for example, a metal layer containing a metal material provided on the outer surface of a corrugated tube made of resin. The exterior member 30 in the above embodiment is not limited to a corrugated tube, and may be, for example, an exterior member that does not have the large diameter portion 31 and the small diameter portion 32.
[0087] The exterior member 30 in the above embodiment may have a slit extending in the length direction of the exterior member 30. In the above embodiment, the electric wire 21 is a high-voltage electric wire, but this is not limited thereto. For example, the electric wire 21 may be a low-voltage electric wire.
[0088] In the electric wire member 20 of the above embodiment, the electromagnetic shielding member is embodied as the braided member 25, but the present invention is not limited to this. For example, the electromagnetic shielding member in the electric wire member 20 may be embodied as a metal foil.
[0089] The braided member 25 in the electric wire member 20 of the above embodiment may be omitted. In the above embodiment, the electric wire member 20 includes two electric wires 21, but is not limited to this. The number of electric wires 21 may be one, or three or more.
[0090] The relative positions of the inverter M1 and the high-voltage battery M2 in the vehicle V are not limited to those in the above embodiment, and may be changed as appropriate depending on the vehicle configuration. In the above embodiment, the multiple on-board devices electrically connected to the wire harness 10 are embodied as the inverter M1 and the high-voltage battery M2, but are not limited thereto. The multiple on-board devices electrically connected to the wire harness 10 are not particularly limited as long as they are electrical devices mounted on the vehicle V.
[0091] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, not by the above meaning, and is intended to include all modifications within the meaning and scope of the claims.
