[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2005-44607 Summary of the Invention

[0006] Problems to be solved by the invention

[0007] In the wire harness described above, since a gap needs to be set between the electric wires and the inner side surface of the exterior member to accommodate tolerance, there is room for improvement in terms of miniaturization of the exterior member.

[0008] Therefore, an object of the present invention is to provide a wire harness capable of achieving miniaturization of exterior components.

[0009] Means for solving problems

[0010] The wiring harness disclosed herein comprises electric wires and a cylindrical outer casing that surrounds the outer periphery of the electric wires, wherein the electric wires comprise: a first electric wire portion having a core wire and an insulating coating covering the core wire; and a second electric wire portion connected to the longitudinal end of the core wire, the second electric wire portion having a soft portion having higher flexibility than the first electric wire portion, the soft portion having a bending portion that is bent in a manner protruding in a direction orthogonal to the longitudinal direction of the second electric wire portion, and the bending portion is arranged on the outside of the outer casing.

[0011] Effects of the Invention

[0012] According to the present disclosure, it is possible to provide a wire harness capable of achieving miniaturization of exterior components. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic cross-sectional view schematically showing a wire harness according to the embodiment.

[0014] Figure 2 is a schematic cross-sectional view for explaining a manufacturing method of a wire harness of this mode. DETAILED DESCRIPTION

[0015] [Explanation of Embodiments of the Present Disclosure]

[0016] Embodiments of the present disclosure are first explained.

[0017] The wire harness of the present disclosure,

[0018] [1] A wire harness comprising: an electric wire; and a cylindrical outer member that surrounds an outer periphery of the electric wire, wherein the electric wire includes: a first electric wire portion including a core wire and an insulating cover layer that covers the core wire; and a second electric wire portion that is connected to a lengthwise end portion of the core wire, the second electric wire portion including a flexible portion that is more flexible than the first electric wire portion, the flexible portion including a bent portion that is bent in a direction orthogonal to a lengthwise direction of the second electric wire portion, the bent portion being disposed outside the outer member.

[0019] According to this structure, by bending of the bent portion of the flexible portion disposed outside the outer member, a positional tolerance of a counterpart member to which the electric wire is connected can be absorbed. Therefore, since it is not necessary to provide a gap for tolerance absorption between the first electric wire portion and an inner side surface of the outer member (or even if a gap is provided, it can be made small), the size of the outer member in a direction orthogonal to the electric wire insertion direction can be reduced.

[0020] [2] The second electric wire portion is composed of a plurality of wires, and the bent portion is formed in a bent shape by press working. According to this structure, the flexible portion including the bent portion can be appropriately formed.

[0021] [3] The second electric wire portion includes a hardened portion that is formed in a state where rigidity is higher than that of the flexible portion by mutually joining the plurality of wires, and the hardened portion is a portion of the second electric wire portion that is connected to the counterpart member. According to this structure, since a metal terminal or the like for connection to the counterpart member does not need to be separately provided in the second electric wire portion composed of a plurality of wires, an increase in the number of components of the wire harness can be suppressed.

[0022] According to this structure, since a metal terminal or the like for connection to the counterpart member does not need to be separately provided in the second electric wire portion composed of a plurality of wires, an increase in the number of components of the wire harness can be suppressed.

[0023] [4] The second electric wire portion includes: a first hardened portion that is the hardened portion; and a second hardened portion that is formed in a state where rigidity is higher than that of the flexible portion by mutually joining the plurality of wires, the second hardened portion being connected to the lengthwise end portion of the core wire of the first electric wire portion. According to this structure, the first electric wire portion and the second electric wire portion can be appropriately connected by the second hardened portion of the second electric wire portion.

[0024] [5] The second cured portion is located on the inner peripheral side of the end surface in the longitudinal direction of the exterior member.

[0025] According to this configuration, the bent portion of the flexible portion can be appropriately arranged outside the exterior member.

[0026] [6] The first electric wire portion and the second electric wire portion are separate components.

[0027] According to this configuration, the flexible portion of the second electric wire portion can be appropriately configured.

[0028] [Details of the embodiments of the present disclosure]

[0029] The following describes a specific example of the wiring harness disclosed in the present invention with reference to the accompanying drawings. In each of the drawings, for the sake of convenience of explanation, a part of the structure is sometimes exaggerated or simplified. In addition, the size ratios of each part are sometimes different in each of the drawings. In addition, "parallel" or "orthogonal" in this specification include not only the cases of strict parallelism or orthogonality, but also the cases of approximately parallelism or approximately orthogonality within the scope of the role and effect of the present embodiment. In addition, the present invention is not limited to these examples, and is intended to include all changes within the meaning and scope equivalent to the scope of the claims as shown in the scope of the claims.

[0030] Figure 1 The wire harness 10 shown is a wire harness used for electrical connection in a battery module (not shown) in a hybrid vehicle, an electric vehicle, or the like, for example.

[0031] The wire harness 10 includes electric wires 11 and a cylindrical exterior member 12 that surrounds the outer circumference of the electric wires 11 in a portion in the longitudinal direction of the electric wires 11 .

[0032] (Structure of Exterior Member 12)

[0033] The outer casing 12 is formed as a whole in an elongated cylindrical shape. Furthermore, the cross-sectional shape perpendicular to the longitudinal direction of the outer casing 12 (i.e., the cross-sectional shape) can be any shape, such as a circular cylinder, an elliptical cylinder, or a polygonal cylinder. The wire 11 is inserted into the interior space of the outer casing 12.

[0034] In this specification, "cylindrical" refers to any shape that is cylindrical as a whole and includes a combination of multiple parts or a shape with a notch in a portion such as a C-shape. The exterior member 12 of this embodiment is formed of a single part.

[0035] The exterior member 12 of this embodiment is configured as, for example, a shielding protector for preventing electromagnetic noise emitted from the electric wire 11 from leaking to the outside. The exterior member 12, serving as a shielding protector, is formed, for example, from a conductor such as metal. Furthermore, the shielding protector can be formed from a metal material such as copper or aluminum.

[0036] (Overall Structure of Electric Wire 11)

[0037] The electric wire 11 includes a first electric wire portion 13 and a second electric wire portion 14. The first electric wire portion 13 and the second electric wire portion 14 are arranged side by side in the longitudinal direction of the electric wire 11.

[0038] (Structure of the First Electric Wire Portion 13)

[0039] The first electric wire portion 13 includes a core wire 15 and an insulating coating 16 that covers the core wire 15 .

[0040] The core wire 15 of the first electric wire portion 13 is formed to have higher rigidity than the second electric wire portion 14. The core wire 15 of this embodiment can be, for example, a columnar conductor made of a solid metal rod or a cylindrical conductor made of a hollow metal tube. Examples of the columnar conductor include a single core wire or a busbar.

[0041] In addition, as the forming material of the core wire 15, for example, a metal material such as copper or aluminum can be used. In addition, the cross-sectional shape perpendicular to the longitudinal direction of the core wire 15 (that is, the cross-sectional shape) can be any shape such as circular, semicircular, polygonal, flat, etc.

[0042] At one end portion of the core wire 15 in the longitudinal direction, a connecting portion 17 is formed which is flattened in a direction perpendicular to the longitudinal direction of the core wire 15 and has a substantially flat plate shape.

[0043] Insulating coating 16, which covers the outer periphery of core wire 15, electrically insulates core wire 15 from the outside over substantially the entire length of core wire 15. Insulating coating 16 may be, for example, lacquer, which is more suitable for miniaturization than synthetic resin coatings. Connecting portion 17 of core wire 15 is not covered with insulating coating 16.

[0044] (Structure of the Second Electric Wire Portion 14)

[0045] The second wire portion 14 of the electric wire 11 is linear. The second wire portion 14 is connected to the connection portion 17 of the core wire 15. A portion of the second wire portion 14 in the longitudinal direction is designed to be more flexible than the first wire portion 13.

[0046] The second electric wire portion 14 is composed of, for example, a plurality of wires 20 and is flexible. For example, a braided wire formed by braiding the plurality of wires 20 or a stranded wire formed by twisting the plurality of wires 20 can be used as the second electric wire portion 14. The plurality of wires 20 can be formed of, for example, a metal material such as copper or aluminum.

[0047] The second electric wire portion 14, composed of a plurality of wires 20 as described above, includes a first connecting portion 21 for connection to a counterpart component (not shown) (in this embodiment, a terminal on the battery module side, etc.); a second connecting portion 22 for connection to the connecting portion 17 of the core wire 15; and a flexible portion 23 for connecting the first connecting portion 21 and the second connecting portion 22. The first connecting portion 21 and the second connecting portion 22 are formed at both ends of the second electric wire portion 14 in the longitudinal direction.

[0048] (Structure of the First Connecting Portion 21)

[0049] The first connecting portion 21 is a solidified portion (first solidified portion) formed by joining together a plurality of wires 20 to form a state with higher rigidity than the flexible portion 23. In the first connecting portion 21, the plurality of wires 20 are joined together (integrated) by, for example, ultrasonic welding or resistance welding. The first connecting portion 21 is formed into a generally flat plate shape that is flattened in a direction perpendicular to the longitudinal direction of the second electric wire portion 14.

[0050] The first connecting portion 21 has a through-hole 24 formed therein, extending through the first connecting portion 21 in the plate thickness direction. Bolts (not shown) are inserted through the through-holes 24 for securing the mating member. The first connecting portion 21 is secured to the mating member by tightening the bolts. By joining and curing the plurality of wires 20 as described above, the first connecting portion 21 has sufficient rigidity to withstand tightening with the bolts (rigidity sufficient to withstand damage or deformation).

[0051] (Structure of the Second Connecting Portion 22)

[0052] The second connection portion 22 is a solidified portion (second solidified portion) formed by joining a plurality of wires 20 to each other so as to have a higher rigidity than the soft portion 23. In the second connection portion 22, the plurality of wires 20 are joined to each other (integrated), for example, by ultrasonic welding or resistance welding. The second connection portion 22 is formed into a substantially flat plate shape that is flattened in a direction perpendicular to the longitudinal direction of the second electric wire portion 14. In addition, the second connection portion 22 is fixed to the connection portion 17 of the core wire 15 by ultrasonic welding or resistance welding. When the second connection portion 22 is fixed to the connection portion 17, the plurality of wires 20 in the second connection portion 22 are joined to each other.

[0053] (Structure of the soft portion 23)

[0054] The flexible portion 23 is formed between the first connecting portion 21 and the second connecting portion 22. Unlike the first connecting portion 21 and the second connecting portion 22, the flexible portion 23 does not undergo solidification due to the bonding of the plurality of wires 20, maintaining the flexibility of the braided or twisted wire composed of the plurality of wires 20. Consequently, the flexible portion 23 has greater flexibility than the first connecting portion 21, the second connecting portion 22, and the first electric wire portion 13.

[0055] The flexible portion 23 has a bent portion 25 formed into a bent shape by a press process described later. The bent portion 25 is bent in a direction ( Figure 1 In the embodiment, the second wire portion 14 protrudes in the direction A), for example, by being bent in a substantially U-shape. Furthermore, in the present embodiment, the longitudinal direction of the second wire portion 14 is substantially parallel to the longitudinal direction of the first wire portion 13. The bent portion 25 of the present embodiment protrudes in, for example, only one direction along the direction A.

[0056] In the electric wire 11 having the above-described structure, the first electric wire portion 13 is arranged inside the outer component 12. On the other hand, the bent portion 25 and the first connecting portion 21 of the second electric wire portion 14 are provided outside the outer component 12. The second connecting portion 22 of the second electric wire portion 14 is located, for example, on the inner peripheral side of the end face 12a in the longitudinal direction of the outer component 12. In other words, in the longitudinal direction of the electric wire 11, the end face 12a of the outer component 12 and the second connecting portion 22 are arranged at the same position as each other. In addition, with respect to the second connecting portion 22, for example, a part of the second connecting portion 22 is located inside the outer component 12, and a part of the second connecting portion 22 is located outside the outer component 12. In addition, the end portion in the direction A of the bent portion 25 protrudes outward, for example, relative to the outer surface of the outer component 12.

[0057] Next, a method of manufacturing the electric wire 11 will be described.

[0058] First, as described above, the second connecting portion 22 of the second electric wire portion 14 is fixed to the connecting portion 17 of the core wire 15 by, for example, ultrasonic welding or resistance welding. At this time, the plurality of wires 20 constituting the second connecting portion 22 are joined to each other.

[0059] Next, as described above, the plurality of wires 20 constituting the second electric wire portion 14 are joined together by, for example, ultrasonic welding or resistance welding, and then solidified to form the first connecting portion 21. Furthermore, by solidifying the first connecting portion 21 and the second connecting portion 22, the flexible portion 23 is formed between the first connecting portion 21 and the second connecting portion 22.

[0060] Then, if Figure 2As shown, the first connecting portion 21 is held by the first holding jig 31. Furthermore, the second connecting portion 22 and the connecting portion 17, which are fixed to each other, are held by the second holding jig 32. Furthermore, while the first connecting portion 21 and the second connecting portion 22 are held, the flexible portion 23 is formed into a straight line. At this point, the through hole 24 is not yet formed in the first connecting portion 21.

[0061] Next, the bent portion 25 is formed in the flexible portion 23 through a stamping process using a pressing jig 33. The pressing jig 33 presses the linear flexible portion 23 in a direction perpendicular to its longitudinal direction. Simultaneously with the pressing of the flexible portion 23 by the pressing jig 33, at least one of the first holding jig 31 holding the first connecting portion 21 and the second holding jig 32 holding the second connecting portion 22 and the connecting portion 17 is moved toward each other. This forms the bent portion 25 into a curved shape that protrudes in the direction A perpendicular to the longitudinal direction of the second electric wire portion 14.

[0062] The operation of this embodiment will be described.

[0063] The bent portion 25 provided on the exterior of the exterior member 12 is formed into a bent shape that projects in the direction A perpendicular to the longitudinal direction of the second electric wire portion 14. Therefore, the bent portion 25 is easily bent primarily in the longitudinal direction of the second electric wire portion 14. Therefore, the bending of the bent portion 25 absorbs positional tolerances of the mating components connected to the longitudinal ends of the electric wire 11. Furthermore, the bending of the bent portion 25 can also absorb misalignment of the mating components, etc., caused by thermal expansion.

[0064] The effects of this embodiment will be described.

[0065] (1) The first electric wire portion 13 is disposed inside the exterior member 12, and the bent portion 25 of the flexible portion 23 is provided outside the exterior member 12. According to this structure, the bending of the bent portion 25 of the flexible portion 23 provided outside the exterior member 12 can absorb positional tolerances of a non-illustrated counterpart component to which the electric wire 11 is connected. Therefore, there is no need to provide a gap between the first electric wire portion 13 and the inner side surface of the exterior member 12 to absorb the tolerances, thereby reducing the size of the exterior member 12 in a direction perpendicular to the insertion direction of the electric wire 11 (along the direction A).

[0066] (2) The second electric wire portion 14 is composed of a plurality of wires 20. The bent portion 25 of the flexible portion 23 is formed into a bent shape by press working. With this configuration, the flexible portion 23 having the bent portion 25 can be appropriately formed.

[0067] (3) The second electric wire portion 14 includes a first connecting portion 21 (first solidified portion) formed by joining a plurality of wires 20 to each other, resulting in a state having a higher rigidity than the flexible portion 23. The first connecting portion 21 is the portion of the second electric wire portion 14 that is connected to a counterpart component (not shown). This structure eliminates the need for a separate metal terminal or the like for connection to a counterpart component in the second electric wire portion 14, thereby reducing the number of components in the wiring harness 10.

[0068] (4) The second electric wire portion 14 includes a second connecting portion 22 (second solidified portion) formed by joining a plurality of wires 20 to each other so as to have a higher rigidity than the flexible portion 23. The second connecting portion 22 is connected to the connecting portion 17 provided at the longitudinal end of the core wire 15. With this structure, the first electric wire portion 13 and the second electric wire portion can be appropriately connected via the second connecting portion 22 serving as the second solidified portion.

[0069] (5) The second connecting portion 22 is located on the inner circumference side of the end face 12a in the longitudinal direction of the exterior member 12. According to this structure, the bent portion 25 of the soft portion 23 can be appropriately arranged outside the exterior member 12. When the second connecting portion 22 is located on the inner circumference side of the end face 12a of the exterior member 12, the frequency of contact between the opening edge of the exterior member 12 and the second connecting portion 22 becomes higher. However, since the plurality of wires 20 are bonded and solidified to each other in the second connecting portion 22, the wires 20 of the second connecting portion 22 caused by the opening edge of the exterior member 12 can be prevented or suppressed from being broken.

[0070] (6) Since the first electric wire portion 13 and the second electric wire portion 14 are separate components, the flexible portion 23 of the second electric wire portion 14 can be appropriately configured.

[0071] This embodiment can be implemented by modifying it as follows: This embodiment and the following modified examples can be implemented in combination with each other within the scope of no technical contradiction.

[0072] The entire second connection portion 22 may be arranged inside the exterior member 12 or outside the exterior member 12 .

[0073] The first connecting portion 21 may be formed by a metal terminal that is independent of the second electric wire portion 14 .

[0074] The material for forming the second electric wire portion 14 is not limited to the above embodiment and can be changed to a conductive member other than a braided wire or a twisted wire composed of a plurality of wires 20 as long as it is more flexible than the first electric wire portion 13 .

[0075] In the above embodiment, the first connection portion 21 is formed after the second connection portion 22 is connected to the connection portion 17. However, this is not particularly limiting. In other words, the second connection portion 22 and the connection portion 17 may be connected after the first connection portion 21 is formed, or the connection of the second connection portion 22 and the connection portion 17 and the formation of the first connection portion 21 may be performed simultaneously.

[0076] The bent shape of the bent portion 25 is not limited to a substantially U-shaped shape protruding in only one direction along the direction A, and can be changed to a substantially V-shaped shape, for example. Furthermore, for example, the bent shape of the bent portion 25 can be a wavy shape when viewed from a direction perpendicular to the longitudinal direction of the second electric wire portion 14 .

[0077] For example, a braided wire composed of a combination of metal wires and resin wires may be used as the braided wire constituting the second electric wire portion 14. For example, a reinforcing fiber having excellent insulation and shear resistance, such as para-aramid fiber, may be used as the resin wire.

[0078] In the above embodiment, the first electric wire portion 13 is disposed entirely in the longitudinal direction inside the exterior member 12 . However, the present invention is not limited thereto. For example, a portion of the first electric wire portion 13 in the longitudinal direction may be located outside the exterior member 12 .

[0079] The insulating coating layer 16 of the above embodiment may be replaced with an insulating coating layer made of synthetic resin.

[0080] As the core wire 15 in the first electric wire portion 13 , for example, a stranded wire formed by stranding a plurality of metal wires can be used. Alternatively, as the core wire 15 , for example, a combination of a stranded wire, a columnar conductor, or a cylindrical conductor may be used.

[0081] The exterior member 12 may be formed of a resin material. As the material for forming the resin exterior member 12, for example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin may be used.

[0082] In the above embodiment, the wire harness 10 is used for electrical connection of a battery module. However, the present invention is not limited thereto and may be applied to a wire harness used for electrical connection of vehicle-mounted equipment other than a battery module.

[0083] ·like Figure 1 As shown, part or all of the bent portion 25 of the second electric wire portion 14 of the embodiment may be arranged outside the opening end of the exterior member 12 in the longitudinal direction of the exterior member 12 .

[0084] ·like Figure 1As shown, when the wiring harness 10 is alone, for example, before the wiring harness 10 is connected to the other component, the second wire portion 14 can be pre-bent so that at least a portion of the bent portion 25 is arranged on the outside in the radial direction of the outer component 12 compared to the outermost surface of the outer component 12.

[0085] The first connecting portion 21 of the embodiment is sometimes referred to as the tip of the second electric wire portion 14 or the first length portion of the second electric wire portion 14. The second connecting portion 22 of the embodiment is sometimes referred to as the base end of the second electric wire portion 14 or the second length portion of the second electric wire portion 14. The flexible portion 23 of the embodiment is sometimes referred to as the intermediate portion between the tip and base ends of the second electric wire portion 14 or the third length portion of the second electric wire portion 14.

[0086] The first connecting portion 21 of the second electric wire portion 14 of the embodiment is sometimes referred to as a first wire joining block, which is compressed and joined over a first length so that the plurality of conductive wires 20 do not move relative to each other. The second connecting portion 22 of the second electric wire portion 14 of the embodiment is sometimes referred to as a second wire joining block, which is compressed and joined over a second length so that the plurality of conductive wires 20 do not move relative to each other. The flexible portion 23 of the second electric wire portion 14 of the embodiment is sometimes referred to as a bundle of conductive wires 20, or a non-joined portion, in which the plurality of conductive wires 20 are movable relative to each other but not joined relative to each other.

[0087] In the second electric wire portion 14 of the embodiment, the volume percentage of the voids of the first connecting portion 21 per unit volume of the first connecting portion 21 is sometimes referred to as the first void ratio. The volume percentage of the voids of the second connecting portion 22 per unit volume of the second connecting portion 22 is sometimes referred to as the second void ratio. The volume percentage of the voids of the soft portion 23 per unit volume of the soft portion 23 is sometimes referred to as the third void ratio. The first void ratio may be the same as or different from the second void ratio. The first void ratio and / or the second void ratio may be smaller than the third void ratio. In other words, in the embodiment, the ratio of the conductor volume per unit volume of the soft portion 23, that is, the conductor volume percentage, may be lower than the volume percentage of the conductor in the first connecting portion 21 and / or may be lower than the volume percentage of the conductor in the second connecting portion 22.

[0088] As shown in the example shown in the figure, the second electric wire portion 14 including the first connecting portion 21 and the second connecting portion 22 may be a braid including the conductive wire 20 or consisting only of the conductive wire 20 and extending continuously and seamlessly from the first connecting portion 21 to the second connecting portion 22 .

[0089] The entire first connecting portion 21 and / or the entire second connecting portion 22 of the embodiment may be constituted by only the wire member 20 .
