Abstract
Description
[Technical field]
[0001] The present disclosure relates to a wire harness. [Background technology]
[0002] For example, the wire harness of Patent Document 1 includes a fixing member that fixes an electric wire member to a vehicle body. The fixing member has a holding portion that holds the electric wire member, and a bolt fixing portion that is fixed to a bolt provided on the vehicle body. The bolt fixing portion has a locking piece that locks with the threaded portion of the bolt in the axial direction. At least a pair of locking pieces are provided so as to sandwich the bolt in a direction perpendicular to the axis. When the fixing member is attached to the bolt, the bolt is inserted into the fixing member. At this time, the locking pieces are pushed by the bolt and bend in directions away from each other. Then, each locking piece is urged toward the bolt by its own elasticity, and locks with the threaded portion of the bolt.
[0003] The bolt fixing portion has a biasing portion that elastically contacts the panel of the vehicle body and applies a biasing force to the panel. The fixing member of the above-mentioned Patent Document 1 has a spring piece as a biasing portion near the bolt insertion opening. The spring pieces are provided in pairs on both sides of the bolt when viewed from a direction perpendicular to the bolt axis. Each of the pair of spring pieces extends from a side surface of the bolt fixing portion facing the panel and extends so as to be separated from each other. The tip of each spring piece is a free end and is located away from the side surface of the bolt fixing portion. The biasing force applied to the panel from each spring piece makes it possible to suppress rattling of the fixing member. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] [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 comprising an electric wire member having an electric wire and a fixing member for fixing the electric wire member to an attachment object, the fixing member having a bolt fixing portion fixed to a bolt of the attachment object and a holding portion for holding the electric wire member, the bolt fixing portion having a side facing the attachment object, a bolt insertion port provided on the side and into which the bolt is inserted, a locking portion for axially locking the bolt inserted from the bolt insertion port into the bolt fixing portion, and a biasing portion provided on the side and in contact with the attachment object, the biasing portion having a pair of elastic pieces extending from the side, the pair of elastic pieces inclined so as to approach each other as they move away from the side, and tips of the pair of elastic pieces facing each other.
[0012] According to this configuration, the tips of the pair of elastic pieces of the urging portion face each other, which prevents the tips of the elastic pieces from getting caught when, for example, the fixing member is transported alone or when the wire harness including the fixing member is assembled to a vehicle, and thus makes it possible to prevent damage to the elastic pieces of the urging portion.
[0013] [2] The biasing portion has a connecting portion that connects the tips of the pair of elastic pieces to each other. According to this configuration, the tips of the pair of elastic pieces are connected to each other by the connecting portion, which makes it possible to improve the rigidity of each elastic piece. Also, the tips of the pair of elastic pieces are connected to each other by the connecting portion, which makes it possible to prevent the tips of each elastic piece from getting caught. Therefore, it is possible to further prevent damage to the elastic pieces.
[0014] [3] The thickness of the connecting portion is thinner than the thickness of each of the elastic pieces. According to this configuration, it is possible to form a connecting portion that connects the tips of the elastic pieces while ensuring the flexibility of each elastic piece.
[0015] [4] A wire harness according to the present disclosure includes an electric wire member having an electric wire, and a fixing member for fixing the electric wire member to an attachment target, the fixing member having a bolt fixing portion fixed to a bolt of the attachment target, and a holding portion for holding the electric wire member, the bolt fixing portion having a side surface facing the attachment target, a bolt insertion port provided on the side surface through which the bolt is inserted, a locking portion for axially locking the bolt inserted from the bolt insertion port into the bolt fixing portion, and a biasing portion provided on the side surface and in contact with the attachment target, the biasing portion having a first connection end connected to the side surface, a second connection end connected to the side surface, and an elastic portion connecting the first connection end and the second connection end and contacting the attachment target to apply a force to the attachment target.
[0016] According to this configuration, the biasing portion does not have a free end that is not connected to the side surface of the bolt fixing portion. Therefore, for example, when the fixing member alone is transported or when the wire harness including the fixing member is assembled to a vehicle, the biasing portion is prevented from getting caught. This makes it possible to prevent damage to the biasing portion.
[0017] [5] The elastic portion has an arc shape that is convex on the side protruding from the side surface. According to this configuration, it is possible for the elastic portion to appropriately apply force to the attachment object.
[0018] [6] A wire harness including an exterior member covering an outer periphery of the electric wire member, and a path regulating member attached to the outer periphery of the exterior member and regulating a path of the exterior member, the path regulating member having an insertion opening that opens in a direction perpendicular to a longitudinal direction of the path regulating member and extends over the entire longitudinal direction of the path regulating member. With this configuration, it is possible to suppress damage to a biasing portion of a bolt fixing portion in a wire harness including a path regulating member.
[0019] [7] The holding portion holds the path regulating member in a manner that covers the entire circumference of the path regulating member, and the holding portion has a protrusion that protrudes toward an inner circumference, and the protrusion is located inside the insertion opening of the path regulating member. With this configuration, it is possible to restrict the rotation of the path regulating member relative to the holding portion by the protrusion of the holding portion.
[0020] [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. Furthermore, the dimensional ratio of each part may differ from one drawing to another. Furthermore, "orthogonal" in this specification does not only mean a case where the two are strictly orthogonal, but also includes a case where the two are approximately orthogonal within the range in which the action and effect of this embodiment can be achieved.
[0021] In this specification, "facing" refers to surfaces or components facing each other, and includes not only cases where they are completely facing each other, but also cases where they are partially facing each other. In addition, in this specification, "facing" refers to both cases where a component separate from the two parts is interposed between the two parts, and cases where nothing is interposed between the two parts.
[0022] (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.
[0023] 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.
[0024] 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.
[0025] (Configuration of the electric wire member 20) As shown in Figures 2 and 3, 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.
[0026] As shown in Fig. 2, 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.
[0027] 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.
[0028] 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.
[0029] 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).
[0030] (Configuration of exterior member 30) As shown in Fig. 3, 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, for example, flying objects and water droplets.
[0031] 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 portions 31 and small diameter portions 32 having a diameter smaller than that of the large diameter portions 31 are alternately arranged along the length direction of the exterior member 30. Each of the large diameter portions 31 and the small diameter portions 32 is, for example, annular in 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.
[0032] (Configuration of the path regulating member 40) 2 and 3, the wire harness 10 includes a path regulating member 40 attached to the outer periphery of the exterior member 30. The path regulating member 40 regulates the route along which the wire harness main body 11 is routed. Note that the path regulating member 40 is not shown in FIG.
[0033] The path regulating member 40 holds the exterior member 30. The path regulating member 40 is, for example, harder than the exterior member 30. The path regulating member 40 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, the path regulating member 40 regulates the path of the wire harness main body 11. For example, the path regulating member 40 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. The path regulating member 40 is partially provided in the length direction of the wire harness main body 11. For example, the path regulating member 40 is attached to the outer periphery of the exterior member 30 at a straight portion 11A, which is a straight portion of the path of the wire harness main body 11.
[0034] As shown in Fig. 2, the 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 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 path regulating member 40 is generally C-shaped. The path regulating member 40 covers, for example, an area larger than half of the outer periphery of the exterior member 30. In other words, the path regulating member 40 covers an area larger than half of the entire circumferential direction of the exterior member 30 in the outer periphery of the exterior member 30.
[0035] The path regulating member 40 extends along the length of the exterior member 30 at the straight portion 11A. The path regulating member 40 is formed, for example, in a shape that extends linearly in one direction. The cross-sectional shape of the path regulating member 40 is, for example, uniform over the entire length of the path regulating member 40 in the length direction.
[0036] The path regulating member 40 is made of, for example, metal or resin. The path regulating member 40 of this embodiment is made of resin. As the material of the path regulating member 40, for example, synthetic resin such as polypropylene, polyamide, polyacetal, etc. can be used. The path regulating member 40 can be manufactured by a well-known manufacturing method such as extrusion molding or injection molding. In this embodiment, the path regulating member 40 is an extrusion molded product manufactured by extrusion molding. Therefore, the path regulating member 40 can be easily manufactured by using an extrusion molding machine that extrudes the raw material of the path regulating member 40 in the length direction. In addition, a single extrusion molding machine can be used to manufacture multiple types of path regulating members 40 with different length dimensions. For example, a cutting machine can be used to cut the base material of the path regulating member 40 formed by a single extrusion molding machine at an arbitrary length, thereby manufacturing multiple types of path regulating members 40 with different length dimensions.
[0037] The path regulating member 40 has an insertion opening 40X that opens in a direction perpendicular to the length direction of the path regulating member 40. The insertion opening 40X extends over the entire length direction of the path regulating member 40. The path regulating member 40 has a first end 41 and a second end 42 that are both ends of the path regulating member 40 in the circumferential direction and form the insertion opening 40X. The path regulating member 40 has a connecting portion 43 that connects the first end 41 and the second end 42. In other words, the 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.
[0038] The connecting portion 43 constitutes a main portion of the path regulating member 40. The radial thickness of the connecting portion 43 is, for example, uniform in the circumferential direction of the 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.
[0039] The first end 41 and the second end 42 are provided on opposite sides of the 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 path regulating member 40 with 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 path regulating member 40 is configured as the insertion opening 40X. In this manner, the path regulating member 40 is formed in a C-shape having the insertion opening 40X at a part of the circumferential direction of the path regulating member 40.
[0040] 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.
[0041] The 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 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 a circular arc shape.
[0042] 3, each of the protrusions 45, 46 extends in the length direction of the path regulating member 40. Each of the protrusions 45, 46 extends, for example, over the entire length of the path regulating member 40 in the length direction.
[0043] The protrusions 45, 46 press the exterior member 30 from the outside of the exterior member 30. The exterior member 30 is elastically sandwiched between the protrusions 45, 46, and the connecting portion 43. This makes the connection of the path regulating member 40 to the exterior member 30 strong.
[0044] As shown in FIG. 2, 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 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 path regulating member 40. When the exterior member 30 is inserted into the inside of the path regulating member 40, the 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 path regulating member 40 is attached to the outer periphery of the exterior member 30.
[0045] (Configuration of fixing member 50) As shown in Fig. 2, the wire harness 10 includes a fixing member 50 for fixing the wire harness main body 11 to a panel P constituting a floor portion of a vehicle V. One or more fixing members 50 are provided in the longitudinal direction of the wire harness main body 11. Note that the fixing member 50 is not shown in Fig. 1. The fixing member 50 holds a portion of the wire harness main body 11 to which, for example, the path regulating member 40 is attached.
[0046] The fixing member 50 is made of, for example, metal or resin. The fixing member 50 of this embodiment is made of resin. As the material of the fixing member 50, for example, synthetic resin such as polypropylene, polyamide, polyacetal, etc. can be used. The fixing member 50 can be manufactured by a well-known manufacturing method such as injection molding.
[0047] As shown in FIGS. 2 and 3, the fixing member 50 has a bolt fixing portion 51 that is fixed to a bolt B extending from the panel P, and a holding portion 52 that holds the wire harness main body 11.
[0048] (Configuration of holding portion 52) The holding portion 52 holds the path regulating member 40 in a manner that covers the entire periphery of the path regulating member 40. The holding portion 52 has a holding portion main body 53 and a lid portion 54 connected to the holding portion main body 53.
[0049] The holding portion main body 53 covers, for example, the outer periphery of the connecting portion 43 of the path regulating member 40. The holding portion main body 53 has an insertion opening 55 covered by a lid portion 54. The insertion opening 55 opens in a direction perpendicular to the longitudinal direction of the wire harness main body 11. The cross-sectional shape of the inner surface of the lid portion 54 is formed into a shape that follows the outer surface of the exterior member 30, for example.
[0050] Lid portion 54 is, for example, formed integrally with holding portion main body 53. Lid portion 54 is connected to holding portion main body 53 by, for example, hinge portion 56. Lid portion 54 is rotatable about hinge portion 56 between an open position and a closed position where it covers insertion opening 55. Note that lid portion 54 shown in Fig. 2 is in the closed position, and lid portion 54 shown in Fig. 3 is in the open position.
[0051] The lid portion 54 also has a locking claw 57. The locking claw 57 is locked by a lock portion 58 provided on the holding portion main body 53 when the lid portion 54 is in the closed position. This causes the lid portion 54 to be held in the closed position. The wire harness main body 11 is held by the holding portion 52 with the insertion opening 40X facing the lid portion 54.
[0052] 2 and 3, the holding portion 52 has a protrusion 59 that protrudes toward the inner periphery, i.e., toward the wire harness main body 11. The protrusion 59 is formed in the holding portion 52 so as to protrude from, for example, the inner surface of the cover portion 54. One or more protrusions 59 are provided.
[0053] When the cover portion 54 is in the closed position, the protrusion 59 is located inside the insertion opening 40X of the path regulating member 40. This makes it possible for the protrusion 59 to regulate the path regulating member 40 from rotating relative to the holding portion 52. In addition, the protrusion 59 fits into the small diameter portion 32 of the exterior member 30. This restricts movement of the exterior member 30 relative to the holding portion 52 in the length direction of the exterior member 30.
[0054] (Configuration of bolt fixing portion 51) The bolt fixing portion 51 is integral with, for example, the holding portion main body 53. The bolt fixing portion 51 has an insertion hole 61 through which the bolt B is inserted. Note that in Figs. 2, 3 and 4, a width direction X, a depth direction Y and a height direction Z are illustrated as three mutually perpendicular directions in the fixing member 50. The bolt B is inserted into the insertion hole 61 along the height direction Z. In addition, the wire harness main body 11 is disposed in the holding portion 52 so that its length direction is along the depth direction Y.
[0055] 2 and 4, the bolt fixing portion 51 has a side surface 51a that faces the panel P when the bolt fixing portion 51 is attached to the vehicle V. The insertion hole 61 is open at one end in the height direction Z at the side surface 51a. That is, the insertion hole 61 has a bolt insertion opening 62, into which the bolt B is inserted, at the side surface 51a. Note that the insertion hole 61 in this embodiment is also open on both sides in the depth direction Y.
[0056] An engagement portion 63 is provided inside the insertion hole 61 to axially engage with the bolt B inserted into the bolt fixing portion 51 from the bolt insertion opening 62. The engagement portions 63 extend, for example, from a pair of inner wall surfaces 64 facing each other in the width direction X of the insertion hole 61. A plurality of engagement portions 63 are arranged side by side, for example, in the height direction Z. The engagement portions 63 are inclined, for example, toward the front side in the insertion direction of the bolt B as they move inward from the pair of inner wall surfaces 64. The engagement portions 63 are axially engaged with the threads of the bolt B at their own tip portions.
[0057] (Configuration of the biasing portion 65) The bolt fixing portion 51 has a biasing portion 65 on the side surface 51a. The biasing portions 65 are located, for example, on both sides of the bolt insertion opening 62 in the depth direction Y. Each biasing portion 65 has a pair of elastic pieces 66 extending from the side surface 51a. The pair of elastic pieces 66 are inclined so as to approach each other as they move away from the side surface 51a. The tips 66a of the pair of elastic pieces 66 face each other. In other words, the positions of the tips 66a in the height direction Z are aligned with each other.
[0058] 2, when viewed from the depth direction Y, the pair of elastic pieces 66 are symmetrical with respect to the central axis L of the bolt insertion opening 62. The central axis L of the bolt insertion opening 62 is aligned along the height direction Z. When viewed from the depth direction Y, the distances from the central axis L to each of the base portions 66b are equal to each other. Also, when viewed from the depth direction Y, the distances from the central axis L to each of the tips 66a are equal to each other.
[0059] The operation of this embodiment will be described. When assembling the fixing member 50 to the bolt B, the bolt B is inserted into the insertion hole 61 of the bolt fixing portion 51 along the height direction Z. As a result, each locking portion 63 is locked to the outer circumferential surface of the bolt B in the axial direction. Also, each elastic piece 66 of each biasing portion 65 elastically contacts the panel P. That is, each elastic piece 66 contacts the panel P in a bent state such that the tip 66a approaches the side surface 51a. As a result, each elastic piece 66 applies a biasing force to the panel P. This makes it possible to suppress rattling of the fixing member 50.
[0060] The effects of this embodiment will be described. (1) The bolt fixing portion 51 has a side surface 51a facing the panel P, and a bolt insertion opening 62 provided in the side surface 51a and into which the bolt B is inserted. The bolt fixing portion 51 also has a locking portion 63 that axially locks the bolt B inserted into the bolt fixing portion 51 from the bolt insertion opening 62, and a biasing portion 65 provided on the side surface 51a and contacts the panel P. The biasing portion 65 has a pair of elastic pieces 66 extending from the side surface 51a. The pair of elastic pieces 66 are inclined so as to approach each other as they move away from the side surface 51a. The tips 66a of the pair of elastic pieces 66 face each other.
[0061] According to this configuration, the tips 66a of the pair of elastic pieces 66 of the urging portion 65 face each other. Therefore, for example, when the fixing member 50 is transported, or when the wire harness 10 including the fixing member 50 is assembled to the vehicle V, the tips 66a of the elastic pieces 66 are prevented from getting caught. This makes it possible to prevent damage to the elastic pieces 66 of the urging portion 65.
[0062] (2) The wire harness 10 includes an exterior member 30 that covers the outer periphery of the electric wire member 20, and a path regulating member 40 that is attached to the outer periphery of the exterior member 30 and regulates the path of the exterior member 30. The path regulating member 40 has an insertion opening 40X that opens in a direction perpendicular to the longitudinal direction of the path regulating member 40 and extends over the entire longitudinal direction of the path regulating member 40. According to this configuration, in the wire harness 10 including the path regulating member 40, it is possible to suppress damage to the urging portion 65.
[0063] (3) The holding portion 52 holds the path regulating member 40 in a manner that covers the entire circumference of the path regulating member 40. The holding portion 52 has a protrusion 59 that protrudes toward the inner circumference. The protrusion 59 is located inside the insertion opening 40X. With this configuration, it is possible to prevent the path regulating member 40 from rotating relative to the holding portion 52 by the protrusion 59 of the holding portion 52.
[0064] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. For example, as shown in FIG. 5, the biasing portion 65 may be provided with a connecting portion 67 that connects the tips 66a of a pair of elastic pieces 66. In the configuration shown in FIG. 5, the thickness T2 of the connecting portion 67 is set to be thinner than the thickness T1 of each elastic piece 66. The thickness T1 of the elastic piece 66 is the thickness of the inclined portion of the elastic piece 66. Furthermore, the thickness T1 of the elastic piece 66 is, for example, uniform at the inclined portion. For example, the thicknesses T1 of the pair of elastic pieces 66 are equal to each other. The connecting portion 67 is, for example, in the shape of a flat plate with a uniform thickness T2.
[0065] According to this configuration, the tips 66a of the pair of elastic pieces 66 are connected to each other by the connecting portion 67, so that the rigidity of each elastic piece 66 can be improved. In addition, the tips 66a of the pair of elastic pieces 66 are connected to each other by the connecting portion 67, so that the tip 66a of each elastic piece 66 can be prevented from being caught. Therefore, damage to the elastic piece 66 can be further prevented. In addition, by making the thickness T2 of the connecting portion 67 thinner than the thickness T1 of each elastic piece 66, it is possible to configure the connecting portion 67 while ensuring the flexibility of each elastic piece 66. Note that when each elastic piece 66 comes into contact with the panel P and bends, the connecting portion 67 is deformed. At this time, even if the connecting portion 67 is cut, there is no problem because the urging force from each elastic piece 66 to the panel P is appropriately generated. In the example shown in FIG. 5, the thickness T2 of the connecting portion 67 is set to be thinner than the thickness T1 of each elastic piece 66, but this is not limited thereto, and the thicknesses T1 and T2 may be set to be equal, or the thickness T2 may be set to be thicker than the thickness T1.
[0066] The biasing portion 65 of the above embodiment may be changed to a biasing portion 70 as shown in FIG. 6. The biasing portion 70 has a first connection end 71, a second connection end 72, and an elastic portion 73. The first connection end 71 is connected to the side surface 51a of the bolt fixing portion 51. The second connection end 72 is connected to the side surface 51a of the bolt fixing portion 51. The elastic portion 73 connects the first connection end 71 and the second connection end 72. The elastic portion 73 has, for example, an arc shape that is convex on the side protruding from the side surface 51a. When viewed from the depth direction Y, the biasing portion 70 is symmetrical with respect to the central axis L of the bolt insertion opening 62. That is, when viewed from the depth direction Y, the distance from the central axis L to the first connection end 71 and the distance from the central axis L to the second connection end 72 are equal to each other. Further, when viewed from the depth direction Y, the apex 74 of the elastic portion 73 overlaps with the central axis L. The apex 74 is the center of the elastic portion 73 in the width direction X, and is the part of the elastic portion 73 that is located farthest from the side surface 51a. The elastic portion 73 contacts the panel P at a part including the apex 74 to apply a biasing force to the panel P.
[0067] According to the above-mentioned configuration, the urging portion 70 does not have a free end, i.e., an end that is not connected to the side surface 51a. Therefore, for example, when the fixing member 50 is transported or when the wire harness 10 including the fixing member 50 is assembled to the vehicle V, the urging portion 70 is prevented from getting caught. This makes it possible to prevent damage to the urging portion 70. In addition, by forming the elastic portion 73 into an arc shape that is convex on the side protruding from the side surface 51a, it becomes possible for the elastic portion 73 to appropriately apply force to the panel P.
[0068] In the above embodiment, the urging portion 65 is provided on both sides of the bolt insertion opening 62 in the depth direction Y, but this is not limited thereto, and the urging portion 65 may be provided on both sides of the bolt insertion opening 62 in the width direction X. The number of the urging portion 65 is not limited to two, and only one, or three or more may be provided. In the above embodiment, the pair of elastic pieces 66 of the urging portion 65 are arranged side by side in the depth direction Y, but this is not limited thereto, and the pair of elastic pieces 66 may be arranged side by side in the depth direction Y.
[0069] In the fixing member 50 of the above embodiment, the insertion opening 55 of the holding portion main body 53 is set to face the panel P, and the lid portion 54 covering the insertion opening 55 faces the panel P, but this is not particularly limited. For example, the insertion opening 55 may be configured to face the opposite side to the bolt fixing portion 51 in the width direction X.
[0070] The structure of the path regulating member 40 in the above embodiment can be modified as appropriate. For example, as long as the 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.
[0071] 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 path regulating member 40. The protrusion 46 in the above embodiment may be provided at a position farther away from the insertion opening 40X than the tip of the second end 42 in the circumferential direction of the path regulating member 40.
[0072] The protrusions 45 and 46 in the above embodiment may be provided partially in the length direction of the path regulating member 40 . At least one of the protruding portions 45, 46 in the above embodiment may be omitted.
[0073] In the path regulating 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 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.
[0074] In the above embodiment, the path regulating member 40 is harder than the exterior member 30, but this is not limiting, and the path regulating member 40 may have a hardness equal to or less than that of the exterior member 30. In other words, the path regulating member 40 only needs to 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 path regulating member 40 is not attached.
[0075] In the holder 52 , the projection 59 may be provided on the holder body 53 instead of on the lid 54 . The fixing member 50 may hold a portion of the wire harness main body 11 that does not have the path regulating member 40. Also, the path regulating member 40 may be omitted from the wire harness 10 of the above embodiment.
[0076] 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.
[0077] 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.
[0078] 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.
[0079] 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.
[0080] 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.
