Summary of the Invention

Problems to be Solved by the Invention

[0004] In the wire harness as described above, with respect to the fixing member attached to the outer member, the position in the length direction of the outer member and the orientation of the outer member may deviate significantly from an appropriate state for fixing to the fixing target. In this case, since the operator needs to fix the fixing member to the fixing target after setting the fixing member in an appropriate position and orientation, the assembling work of assembling the fixing member attached to the outer member to the fixing target becomes complicated.

[0005] An object of the present disclosure is to provide a wire harness that enables improvement in assembling property.

Means for Solving the Problems

[0006] The wire harness of this disclosure comprises an electric wire, a cylindrical outer covering member covering the outer circumference of the electric wire, and a fixing member for fixing the outer covering member to a fixing object, wherein the outer covering member comprises a first portion extending linearly along a first direction and a second portion extending from the end of the first portion in the first direction in a second direction intersecting the first direction, and the fixing member comprises a mounting portion attached to the first portion so as to cover the outer circumference of the first portion, a fixing portion fixed to the fixing object, and a restricting portion configured to abut against the second portion and restricting the movement of the fixing member by abutting against the second portion. [Effects of the Invention]

[0007] The wire harness of this disclosure enables improved assembly. [Brief explanation of the drawing]

[0008] [Figure 1] Figure 1 is a perspective view showing a portion of a wire harness according to one embodiment. [Figure 2] Figure 2 is a plan view of the fixing member in the same embodiment. [Figure 3] Figure 3 is a perspective view showing a portion of the wire harness of the same embodiment. [Figure 4] Figure 4 is a side view of the wire harness of the same embodiment, viewed from a direction along the central axis L1. [Modes for carrying out the invention]

[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. The wire harness in this disclosure is [1] A wire harness comprising an electric wire, a cylindrical outer covering member covering the outer circumference of the electric wire, and a fixing member for fixing the outer covering member to a fixing object, wherein the outer covering member comprises a first portion extending linearly along a first direction and a second portion extending from the end of the first portion in the first direction in a second direction intersecting the first direction, and the fixing member comprises a mounting portion attached to the first portion so as to cover the outer circumference of the first portion, a fixing portion fixed to the fixing object, and a restricting portion configured to abut against the second portion and restricting the movement of the fixing member by abutting against the second portion.

[0010] With this configuration, the movement of the fixing member is restricted by the regulating part contacting the second part of the exterior member, which prevents significant displacement of the fixing member's position and orientation. As a result, it becomes possible to improve the ease of assembly when attaching the fixing member to the object to be fixed.

[0011] [2] In the above [1], the restricting portion may include a first slide restricting portion that restricts the movement of the fixing member in the first direction by contacting the second portion. With this configuration, the first slide restricting portion contacts the second portion of the exterior member in the first direction, thereby restricting the movement of the fixing member in the first direction, and thus making it possible to suppress significant displacement of the fixing member's position in the first direction.

[0012] [3] In the above [1] or [2], the restricting portion may include a second sliding restricting portion that contacts the second portion to restrict the movement of the fixing member in a third direction opposite to the first direction.

[0013] With this configuration, the second slide restricting portion contacts the second portion of the exterior member in the third direction, thereby restricting the movement of the fixing member in the third direction. This makes it possible to suppress significant displacement of the fixing member's position in the third direction.

[0014] [4] In any of the above [1] to [3], the restricting portion may include a rotation restricting portion that contacts the second portion to restrict the rotation of the fixing member about the central axis of the first portion.

[0015] With this configuration, the rotation restricting part contacts the second part of the exterior member, thereby restricting the rotation of the fixing member around the central axis of the first part of the exterior member. This makes it possible to suppress significant deviations in the orientation of the fixing member.

[0016] [5] In the above [4], the rotation restricting portion may include a first rotation restricting portion that contacts the second portion to restrict the rotation of the fixed member in a first rotational direction about the central axis, and a second rotation restricting portion that contacts the second portion to restrict the rotation of the fixed member in a second rotational direction opposite to the first rotational direction.

[0017] With this configuration, the first rotation restricting part and the second rotation restricting part restrict the rotation of the fixed member in both directions around the central axis of the first part, making it possible to further suppress significant deviations in the orientation of the fixed member.

[0018] [Details of the embodiments of this disclosure] A specific example of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, a part of the configuration may be shown in an exaggerated or simplified manner. Also, the dimensional ratios of each part may be different in each drawing. In this specification, "vertical" and "orthogonal" include not only the cases of strict verticality and orthogonality, but also the cases that are generally vertical and orthogonal within the range where the actions and effects in the present embodiment are achieved. The "cylindrical shape" used in the description of this specification includes not only those in which the peripheral wall is continuously formed over the entire circumference in the circumferential direction, but also those in which a plurality of parts are combined to form a cylindrical shape, and those having a notch or the like in a part of the circumferential direction such as a C shape. The outer peripheral shape of the "cylindrical shape" includes, but is not limited to, a circular shape, an elliptical shape, and a polygon having sharp or rounded corners. The "cylindrical shape" is a shape having a through-hole in a plan view, and includes those in which the outer peripheral shape and the inner peripheral shape of the through-hole are the same shape, and those in which the outer peripheral shape and the inner peripheral shape of the through-hole are different shapes. The "cylindrical shape" includes those having a predetermined length extending along the axial direction in which the central axis passing through the center of the through-hole extends, regardless of the size of the length. Also, terms such as "first", "second", "third", etc. in this specification are merely used to distinguish objects, and do not rank the objects. The present invention is not limited to these examples, and is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0019] (Configuration of wire harness 10) The wire harness 10 shown in FIG. 1 includes an electric wire 11, an exterior member 20, and a fixing member 30. The wire harness 10 electrically connects, for example, two or more electrical devices mounted on a vehicle. The wire harness 10 is connected to, for example, a high-voltage battery (not shown) mounted on a hybrid vehicle or an electric vehicle. The high-voltage battery is, for example, a battery capable of supplying a voltage of several hundred volts. Also, the wire harness 10 is routed, for example, through the underfloor of the vehicle. The wire harness 10 is fixed to a fixing target Fa such as a vehicle body panel by the fixing member 30.

[0020] (Configuration of electric wire 11) The wire harness 10 includes one or more electric wires 11. The electric wire 11 is, for example, a high-voltage electric wire capable of handling high voltage and large current. The electric wire 11 is connected to the electric device via a connector (not shown). The electric wire 11 is, for example, a coated electric wire in which an insulating coating is provided on the outer periphery of a core wire made of a conductor. The outer periphery of the electric wire 11 is covered by an exterior member 20.

[0021] (Configuration of the exterior member 20) The exterior member 20 has an overall long cylindrical shape. The exterior member 20 is formed so as to surround the outer periphery of the electric wire 11 over the entire circumference in most of the length direction of the electric wire 11. That is, the electric wire 11 is inserted inside the exterior member 20. The exterior member 20 is formed by being bent in a two-dimensional or three-dimensional shape according to, for example, the routing path of the wire harness 10. The cross-sectional shape of the exterior member 20 is, for example, an annular shape. Also, the exterior member 20 has, for example, a uniform cross-sectional shape in the length direction. The shape of the outer peripheral surface of the exterior member 20 viewed from the length direction is, for example, substantially circular. The exterior member 20 is formed of a metal material such as aluminum, for example. The exterior member 20 protects the electric wire 11 from flying objects and water droplets, for example. The exterior member 20 is fixed to a fixation target Fa by a fixing member 30.

[0022] The exterior member 20 includes a first part 21 and a second part 22. The first part 21 of the exterior member 20 extends linearly along a first direction D1 which is a linear direction. The second part 22 extends from an end 21a of the first part 21 in the first direction D1 to a second direction D2 that intersects the first direction D1. That is, the exterior member 20 includes a bent part 23 where the first part 21 and the second part 22 intersect between the first part 21 and the second part 22. In the following description, the central axis along the first direction D1 in the first part 21 of the exterior member 20 is referred to as the central axis L1.

[0023] (Configuration of the fixing member 30) The fixing member 30 is attached to the outer circumferential surface of the exterior member 20. The fixing member 30 is a member for fixing the exterior member 20 to the object Fa to be fixed. The fixing member 30 is mainly made of, for example, a resin material.

[0024] As shown in Figures 1, 2, and 3, the fixing member 30 comprises a mounting portion 31 attached to the exterior member 20, a first extension portion 32, a second extension portion 33, and a fixing portion 34. In the fixing member 30 of this embodiment, for example, the mounting portion 31, the first extension portion 32, the second extension portion 33, and the fixing portion 34 are formed as a continuous, integral part.

[0025] (Configuration of mounting section 31) The mounting portion 31 as a whole is cylindrical in shape, surrounding the outer circumference of the exterior member 20. The mounting portion 31 has, for example, a mounting portion body 35 and a cover portion 36. The cover portion 36 is, for example, integrally formed with the mounting portion body 35. The mounting portion body 35 and the cover portion 36 are connected to each other, for example, via a hinge portion 37. The mounting portion body 35, the cover portion 36 and the hinge portion 37 are integrally formed. The cover portion 36 is rotatable relative to the mounting portion body 35 about the hinge portion 37 as an axis.

[0026] As shown in Figure 2, the lid portion 36 has a locking portion 36a that engages with a locking portion 35a provided on the mounting portion body 35. When the locking portion 36a engages with the locking portion 35a, the lid portion 36 is held in a closed state. When the lid portion 36 is in the closed state, the mounting portion 31 has a cylindrical shape that surrounds and holds the outer circumference of the first portion 21 of the exterior member 20.

[0027] The lid portion 36 of the mounting portion 31 is provided with a plurality of contact protrusions 36b. Figure 2 shows the state in which the lid portion 36 of the mounting portion 31 is open. Each contact protrusion 36b protrudes from the inner surface of the lid portion 36 into the inside of the mounting portion 31. The plurality of contact protrusions 36b are arranged side by side along the first direction D1. The mounting portion body 35 is provided with elastic pieces 35b. The mounting portion body 35 is provided with, for example, two elastic pieces 35b. When the lid portion 36 is closed, each elastic piece 35b presses the exterior member 20 toward the lid portion 36. That is, when the lid portion 36 is closed, each elastic piece 35b and each contact protrusion 36b clamp the exterior member 20.

[0028] (Configuration of the first extension portion 32 and the fixed portion 34) In the fixing member 30, the first extension 32 extends from the mounting body 35 in a direction perpendicular to the central axis L1. The fixing part 34 is provided on the first extension 32. The fixing part 34 is fixed to the object to be fixed Fa by, for example, a bolt (not shown). A metal collar through which the bolt is inserted may be embedded in the fixing part 34.

[0029] (Configuration of the second extension section 33) The second extension portion 33 of the fixing member 30 extends from the mounting body 35 and includes a portion that extends along the second direction D2. In the fixing member 30 of this embodiment, the second extension portion 33 is, for example, a portion for holding a second wire harness (not shown) that is arranged alongside the wire harness 10.

[0030] (Structure of the regulatory department) The fixing member 30 comprises a first slide restricting portion 41, a second slide restricting portion 42, a first rotation restricting portion 43, and a second rotation restricting portion 44. The first slide restricting portion 41, the second slide restricting portion 42, the first rotation restricting portion 43, and the second rotation restricting portion 44 are included in restricting portions that restrict the movement of the fixing member 30 by contacting the second portion 22 of the exterior member 20. The first rotation restricting portion 43 and the second rotation restricting portion 44 are included in rotation restricting portions that restrict the rotation of the fixing member 30 about the central axis L1 by contacting the second portion 22.

[0031] (Configuration of the first slide regulating section 41) As shown in Figures 1 and 3, the first slide restricting portion 41 is configured to contact the second portion 22 of the exterior member 20 in the first direction D1 when the fixing member 30 moves in the first direction D1. In the fixing member 30 of this embodiment, the first slide restricting portion 41 is, for example, the end portion in the first direction D1 of the lid portion 36 of the mounting portion 31. The first slide restricting portion 41 restricts the movement of the fixing member 30 in the first direction D1 by contacting the second portion 22.

[0032] (Configuration of the second slide regulating section 42) The second slide restricting portion 42 is configured to contact the second portion 22 of the exterior member 20 in the third direction D3 when the fixing member 30 moves in the third direction D3. In the fixing member 30 of this embodiment, the second slide restricting portion 42 is, for example, a wall portion erected from the edge of the second extension portion 33. The second slide restricting portion 42 restricts the movement of the fixing member 30 in the third direction D3 by contacting the second portion 22.

[0033] (Configuration of the first rotation regulating unit 43) As shown in Figure 4, the first rotation restricting portion 43 is configured to contact the second portion 22 of the exterior member 20 in the first rotation direction R1 when the mounting portion 31 of the fixing member 30 rotates in the first rotation direction R1 about the central axis L1. In the fixing member 30 of this embodiment, the first rotation restricting portion 43 is, for example, a wall portion erected at the tip of the second extension portion 33. By contacting the second portion 22, the first rotation restricting portion 43 restricts the rotation of the fixing member 30 in the first rotation direction R1 about the central axis L1.

[0034] (Configuration of the second rotation regulating section 44) The second rotation restricting portion 44 is configured to contact the second portion 22 of the exterior member 20 in the second rotation direction R2 when the mounting portion 31 of the fixing member 30 rotates in the second rotation direction R2, which is opposite to the first rotation direction R1, about the central axis L1. In the fixing member 30 of this embodiment, the second rotation restricting portion 44 is, for example, a wall portion erected on the second extension portion 33. By contacting the second portion 22, the second rotation restricting portion 44 restricts the rotation of the fixing member 30 in the second rotation direction R2 about the central axis L1.

[0035] (Operation of this embodiment) The operation of this embodiment will be described below. The movement of the fixing member 30 is restricted when the first slide restricting part 41, the second slide restricting part 42, the first rotation restricting part 43, and the second rotation restricting part 44 come into contact with the second portion 22 of the exterior member 20.

[0036] The fixing member 30 is movable in the first direction D1 until the first slide restricting portion 41 contacts the second portion 22 of the exterior member 20. Furthermore, the fixing member 30 is movable in the third direction D3 until the second slide restricting portion 42 contacts the second portion 22 of the exterior member 20. As a result, slight movement of the fixing member 30 in the direction along the central axis L1 (first direction D1 and third direction D3) is permitted, and positional tolerances between the fixing member 30 and the object to be fixed Fa in the direction along the central axis L1 can be absorbed.

[0037] Furthermore, the fixing member 30 is rotatable in the first rotation direction R1 until the first rotation restricting portion 43 contacts the second portion 22 of the exterior member 20. Also, the fixing member 30 is rotatable in the second rotation direction R2 until the second rotation restricting portion 44 contacts the second portion 22 of the exterior member 20. As a result, a slight rotation of the fixing member 30 around its central axis L1 is permitted, which allows for the absorption of positional tolerances (angle tolerances with respect to the central axis L1) between the fixing member 30 and the object Fa to be fixed.

[0038] (Effects of this embodiment) The effects of this embodiment will be described below. (1) The fixing member 30 is equipped with restricting parts (first slide restricting part 41, second slide restricting part 42, first rotation restricting part 43 and second rotation restricting part 44) that restrict the movement of the fixing member 30 by contacting the second part 22 of the exterior member 20. With this configuration, the movement of the fixing member 30 is restricted by the restricting parts contacting the second part 22 of the exterior member 20, so it is possible to suppress significant deviations in the position and orientation of the fixing member 30, and as a result it is possible to improve the ease of assembly when attaching the fixing member 30 to the object to be fixed Fa.

[0039] (2) The restricting portion includes a first slide restricting portion 41 that contacts a second portion 22 of the exterior member 20 to restrict the movement of the fixing member 30 in the first direction D1. With this configuration, the movement of the fixing member 30 in the first direction D1 is restricted because the first slide restricting portion 41 contacts the second portion 22 of the exterior member 20 toward the first direction D1, making it possible to suppress the position of the fixing member 30 from shifting significantly toward the first direction D1.

[0040] (3) The restricting portion includes a second slide restricting portion 42 that contacts the second portion 22 of the exterior member 20 to restrict the movement of the fixing member 30 in the third direction D3, which is opposite to the first direction D1. With this configuration, the movement of the fixing member 30 in the third direction D3 is restricted because the second slide restricting portion 42 contacts the second portion 22 of the exterior member 20 toward the third direction D3, making it possible to suppress the position of the fixing member 30 from shifting significantly toward the third direction D3.

[0041] (4) The restricting portion includes a rotation restricting portion (first rotation restricting portion 43 and second rotation restricting portion 44) that contacts the second portion 22 of the exterior member 20 to restrict the rotation of the fixing member 30 about the central axis L1 of the first portion 21. With this configuration, the rotation restricting portion contacts the second portion 22 of the exterior member 20 to restrict the rotation of the fixing member 30 about the central axis L1 of the first portion 21 of the exterior member 20, thereby making it possible to suppress a significant deviation in the orientation of the fixing member 30.

[0042] (5) The rotation restricting portion includes a first rotation restricting portion 43 that contacts the second portion 22 of the exterior member 20 to restrict the rotation of the fixing member 30 in a first rotation direction R1 about the central axis L1, and a second rotation restricting portion 44 that contacts the second portion 22 of the exterior member 20 to restrict the rotation of the fixing member 30 in a second rotation direction R2 opposite to the first rotation direction R1. With this configuration, the rotation of the fixing member 30 in both directions about the central axis L1 of the first portion 21 is restricted by the first rotation restricting portion 43 and the second rotation restricting portion 44, so that the orientation of the fixing member 30 does not shift significantly.

[0043] (Other embodiments) The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0044] The configurations of the first slide restricting section 41, the second slide restricting section 42, the first rotation restricting section 43, and the second rotation restricting section 44 are not limited to the configurations of the above embodiment, and can be appropriately changed according to the configuration of the exterior member 20.

[0045] In the fixing member 30, one, two, or three of the first slide restricting portion 41, the second slide restricting portion 42, the first rotation restricting portion 43, and the second rotation restricting portion 44 may be omitted. The exterior component 20 may be made of a material other than metal, such as resin.

[0046] The shape of the mounting portion 31 in the above embodiment is not particularly limited. The shape of the mounting portion 31 is not particularly limited as long as it is a shape that can hold the exterior member 20. • In the mounting portion 31 of the fixing member 30, the cover portion 36 may be separate from the mounting portion body 35.

[0047] The electric wire 11 inserted inside the exterior member 20 may be, for example, a low-voltage wire connecting a low-voltage battery to various low-voltage devices (e.g., lamps, car audio systems, etc.). The embodiments disclosed herein are illustrative in all respects, and the present invention is not limited to these examples. That is, the scope of the present invention is indicated by the claims, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
