[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The wire harness of the present disclosure includes: [1] The device comprises an electric wire, a metal braided member covering the outer periphery of the electric wire along the extending direction of the electric wire, and a metal pipe through which both the electric wire and the metal braided member pass.

[0010] According to this configuration, the electric wire is doubly covered by the metal braid member and the metal pipe, which can further suppress the radiation of electromagnetic waves compared to when the electric wire is covered only by the metal braid member or only by the metal pipe.

[0011] [2] It is preferable that the length of the metal braided member in the direction in which the electric wire extends is longer than the length of the metal pipe in the direction in which the electric wire extends. According to this configuration, the electric wire inside the metal pipe is covered with the metal braid member in the entire area in the extension direction, which further suppresses electromagnetic wave radiation in the entire area. In addition, the metal braid member extends to the outside of the metal pipe, which makes it easy to connect to other components.

[0012] [3] It is preferable that the end of the metal braided member in the direction in which the electric wire extends has a folded-back portion that is folded back at the end of the metal pipe in the direction in which the electric wire extends and is connected to the outer peripheral surface of the metal pipe.

[0013] According to this configuration, the metal braided member can be easily connected to the metal pipe by the folded-back portion of the metal braided member. [4] It is preferable that the outer surface of the metal pipe has a painted portion that is painted to indicate that it is for use with high-voltage electrical wires, and an unpainted portion where the metal is exposed and the folded portion is connected.

[0014] According to this configuration, the painted portion indicates that the metal braid member is for use with high-voltage electrical wires, and the unpainted portion allows the metal braid member to be easily connected to a metal pipe. [5] At least one of the metal braid member and the metal pipe is preferably made of an iron-based metal material.

[0015] According to this configuration, it is possible to suppress the radiation of electromagnetic waves in a frequency band that is of concern when the material of the body of a vehicle in which the wire harness is installed is replaced from a general iron-based metal material to another material. That is, when the material of the vehicle body is replaced from a general iron-based metal material to another material, there is a risk that electromagnetic waves in a frequency band that were previously absorbed by the body will become less absorbed, raising concerns about the adverse effects of electromagnetic waves in that frequency band. In response to this, the radiation of electromagnetic waves in that frequency band can be suppressed by the wire harness.

[0016] [6] It is preferable that the metal braided member and the metal pipe are made of different metal materials. This configuration makes it possible to suppress radiation of electromagnetic waves over a wide frequency band.

[0017] [7] It is preferable that the metal braid member is made of a copper-based or aluminum-based metal material, and the metal pipe is made of an iron-based metal material. This configuration can suppress radiation of electromagnetic waves in a wide frequency band. It can also suppress radiation of electromagnetic waves in a frequency band that is of concern when the material of the vehicle body in which the wire harness is installed is replaced from a general iron-based metal material to another material. That is, when the material of the vehicle body is replaced from a general iron-based metal material to another material, there is a risk that electromagnetic waves in a frequency band that were previously absorbed by the body will become less absorbed, raising concerns about the adverse effects of electromagnetic waves in that frequency band. In response to this, radiation of electromagnetic waves in that frequency band can be suppressed by the wire harness.

[0018] [8] It is preferable that the metal braid member is a first metal braid member and includes a second metal braid member that covers the outer periphery of the electric wire in a region different from the first metal braid member along the extension direction of the electric wire, and an outer casing member through which both the electric wire and the second metal braid member pass.

[0019] According to this configuration, the electric wire can suppress radiation of electromagnetic waves in the area covered by the second metal braided member. [9] It is preferable to include a fixing member that connects and fixes the first braided metal member and the second braided metal member.

[0020] According to this configuration, the first braided metal member and the second braided metal member can be easily connected without performing complicated operations such as welding.

[10] Preferably, the length of the electric wire in the first metal braid member in the extension direction is longer than the length of the electric wire in the metal pipe in the extension direction, the end of the electric wire in the first metal braid member in the extension direction has a folded portion that is folded back at the end of the electric wire in the metal pipe in the extension direction and connected to the outer peripheral surface of the metal pipe, the end of the electric wire in the second metal braid member in the extension direction has a covering portion that covers the folded portion, and the fixing member is a crimped member that is provided to surround the metal pipe, the folded portion, and the covering portion while using the metal pipe as a base and is crimped to fix it.

[0021] According to this configuration, the electric wire inside the metal pipe is also covered by the first metal braid member in the entire area in its extension direction, thereby further suppressing electromagnetic wave radiation in all areas. The folded portion of the first metal braid member and the covered portion of the second metal braid member are connected to the metal pipe together by crimping the members to the metal pipe as a base. This reduces the number of manufacturing steps and simplifies the configuration compared to a configuration in which the first metal braid member, the second metal braid member, and the metal pipe are connected at two or more points.

[0022]

[11] It is preferable that a waterproof member be provided to collectively cover the portion of the metal pipe that comes into contact with the folded portion, the folded portion, the covering portion, and the crimping member. According to this configuration, the waterproof member can collectively prevent the area of ​​the metal pipe that comes into contact with the folded portion, the folded portion, the covering portion, and the crimping member from being wet.

[0023] [Details of the embodiments 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 ratios of each part may differ between drawings. In this specification, "parallel," "orthogonal," and "circular" do not only refer to strictly parallel, orthogonal, or circular, but also include approximately parallel, orthogonal, or circular within the scope of the effects of this embodiment. Note that the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0024] (Schematic configuration of wire harness 10) As shown in FIG. 1 , a wire harness 10 is mounted on a vehicle V, such as a hybrid vehicle or an electric vehicle. The wire harness 10 electrically connects two or more on-board devices. The on-board devices are electrical devices mounted on the vehicle V. The wire harness 10 electrically connects, for example, an inverter M1 installed in the front of the vehicle V and a high-voltage battery M2 installed in the rear of the vehicle V. The wire harness 10 is formed in an elongated shape so as to extend in the fore-and-aft direction of the vehicle V. The wire harness 10 is routed in the vehicle V so that, for example, an intermediate portion of the wire harness 10 in the extending direction passes outside the passenger compartment of the vehicle V, such as under the floor of the vehicle V.

[0025] The inverter M1 is connected to, for example, a wheel drive motor (not shown) that serves as a power source for running the vehicle. The inverter M1 generates AC power from DC power from a high-voltage battery M2 and supplies the AC power to the motor. The high-voltage battery M2 is, for example, a battery capable of supplying a voltage of several hundred volts.

[0026] (Configuration of wire harness 10) The wire harness 10 includes an electric wire 20. The wire harness 10 includes connectors C1 and C2 attached to both ends of the electric wire 20. One end of the electric wire 20 in the extending direction is connected to an inverter M1 via the connector C1. The other end of the electric wire 20 in the extending direction is connected to a high-voltage battery M2 via the connector C2.

[0027] As shown in FIG. 2, the wire harness 10 includes a first metal braided member 21 as a metal braided member, a metal pipe 22, a second metal braided member 23, an exterior member 24, a crimping member 25 as a fixing member, and a waterproof member 26.

[0028] (Configuration of electric wire 20) 3, the electric wire 20 has a core wire 20a and an insulating coating 20b that covers the outer periphery of the core wire 20a. The wire harness 10 of this embodiment has two electric wires 20. The electric wires 20 are high-voltage wires that can handle high voltages and large currents.

[0029] (Configuration of first metal braided member 21) The first metal braided member 21 covers the outer periphery of the electric wire 20 along the extension direction of the electric wire 20. The first metal braided member 21 of this embodiment covers two electric wires 20 together. The first metal braided member 21 collectively suppresses radiation of electromagnetic waves from the two electric wires 20. The first metal braided member 21 of this embodiment is made of a copper-based metal material containing copper as a main component. The first metal braided member 21 is a braided wire in which element wires made of a copper-based metal material are braided into a tubular shape. The first metal braided member 21 can be folded back, bundled, expanded in diameter, or deformed, and is shown schematically in each drawing.

[0030] (Configuration of metal pipe 22) The metal pipe 22 is penetrated by both the electric wires 20 and the first metal braided member 21. In other words, the metal pipe 22 further covers the outer periphery of the first metal braided member 21 which covers the electric wires 20. The metal pipe 22 of this embodiment is formed in the shape of a perfect cylinder. The metal pipe 22 collectively suppresses the radiation of electromagnetic waves from the two electric wires 20. The metal pipe 22 is made of a metal material different from that of the first metal braided member 21. The metal pipe 22 of this embodiment is made of an iron-based metal material whose main component is iron.

[0031] 2, the outer circumferential surface of the metal pipe 22 has a painted portion 22a that is painted to indicate that it is for use as a high-voltage electrical wire, and an unpainted portion 22b where the metal is exposed without being painted. The unpainted portion 22b is provided at the end of the extension direction of the metal pipe 22. The extension direction of the metal pipe 22, the extension direction of the electric wire 20, and the extension direction of the first metal braided member 21 are the same direction. The painted portion 22a in this embodiment is painted in orange. The metal pipe 22 in this embodiment is arranged to pass, for example, under the floor of the vehicle V, and regulates the path of the electric wire 20, for example, by preventing the electric wire 20 from sagging.

[0032] As shown in Fig. 4, the length of the first metal braided member 21 is longer than the length of the metal pipe 22. Fig. 4 illustrates the first metal braided member 21 and the like in the manufacturing process of the wire harness 10. Although not shown in Fig. 4, the first metal braided member 21 of this embodiment protrudes outward from both ends of the metal pipe 22 in the extension direction of the metal pipe 22.

[0033] 5, the end of the first metal braided member 21 in the extension direction has a folded-back portion 21a that is folded back at the end of the metal pipe 22 in the extension direction and connected to the outer circumferential surface of the metal pipe 22. Note that Fig. 5 illustrates the first metal braided member 21 and the like in the manufacturing process of the wire harness 10 after Fig. 4. The folded-back portion 21a is connected to an unpainted portion 22b of the metal pipe 22.

[0034] (Configuration of second metal braided member 23) As shown in FIG. 2 , the second metal braided member 23 covers the outer periphery of the electric wire 20 in a region different from the first metal braided member 21 along the extension direction of the electric wire 20. Note that a first region R1 where the first metal braided member 21 covers the electric wire 20 and a second region R2 where the second metal braided member 23 covers the electric wire 20 partially overlap. The second metal braided member 23 of this embodiment covers two electric wires 20 together. The second metal braided member 23 collectively suppresses electromagnetic wave radiation from the two electric wires 20. The second metal braided member 23 of this embodiment is made of a copper-based metal material containing copper as a main component. The second metal braided member 23 is a braided wire in which element wires made of a copper-based metal material are braided into a tubular shape. Note that the second metal braided member 23 can be folded back, bundled, expanded in diameter, or deformed, and is illustrated schematically in each drawing.

[0035] (Configuration of exterior member 24) The exterior member 24 is penetrated by both the electric wires 20 and the second metal braided member 23. In other words, the exterior member 24 further covers the outer periphery of the second metal braided member 23 which covers the electric wires 20. The exterior member 24 of this embodiment is a corrugated tube that is flexible and can be easily bent. That is, the exterior member 24 is made of resin and has a bellows shape with a diameter that repeatedly increases and decreases in the extension direction. The exterior member 24 of this embodiment is disposed, for example, in a portion that bends from under the floor of the vehicle V toward above the vehicle V.

[0036] As shown in Fig. 4, the length of the second metal braided member 23 is longer than the length of the exterior member 24. Although not shown in Fig. 4, the second metal braided member 23 of this embodiment protrudes outward in the extension direction of the exterior member 24 at both ends of the exterior member 24.

[0037] 6, the end portion in the extension direction of the second metal braided member 23 has a covering portion 23a that covers the folded-back portion 21a. The covering portion 23a is arranged so that its diameter is expanded outside the exterior member 24 and covers the folded-back portion 21a. Note that FIG. 6 illustrates the first metal braided member 21, the second metal braided member 23, etc. in the manufacturing process of the wire harness 10 after FIG.

[0038] (Configuration of caulking member 25) As shown in FIG. 2, the crimping member 25 connects and fixes the first metal braided member 21 and the second metal braided member 23. More specifically, the crimping member 25 is made of a metal ring. The crimping member 25 is provided so as to surround the metal pipe 22, the folded-back portion 21a, and the covered portion 23a, using the metal pipe 22 as a base, and is crimped and fixed. That is, the folded-back portion 21a and the covered portion 23a are sandwiched between the metal pipe 22 and the crimping member 25, and are electrically connected to the metal pipe 22. The region where the first region R1 and the second region R2 overlap is the region where the covered portion 23a covers the folded-back portion 21a.

[0039] (Configuration of waterproof member 26) The waterproof member 26 collectively covers the portions of the metal pipe 22 that come into contact with the folded-back portion 21a, i.e., the unpainted portion 22b, the folded-back portion 21a, the coated portion 23a, and the crimping member 25. The waterproof member 26 of this embodiment is made of an elastic material such as rubber and is formed in a cylindrical shape. One end 26a of the waterproof member 26 in the extension direction is disposed so as to cover the outer periphery of the painted portion 22a of the metal pipe 22, and the other end 26b of the waterproof member 26 in the extension direction is disposed so as to cover the outer periphery of the exterior member 24. The waterproof member 26 is fixed in close contact with the outer periphery of the painted portion 22a of the metal pipe 22 by fastening the outer periphery of the one end 26a with a resin cable tie 27. The waterproof member 26 is also fixed in close contact with the outer periphery of the exterior member 24 by fastening the outer periphery of the other end 26b with a resin cable tie 28.

[0040] Next, the operation of the wire harness 10 configured as above will be described. The radiation of electromagnetic waves is suppressed by covering the electric wires 20 in a portion corresponding to the metal pipe 22 with the metal pipe 22 and the first metal braided member 21. Moreover, the radiation of electromagnetic waves is suppressed by covering the electric wires 20 in a portion corresponding to the exterior member 24 with the second metal braided member 23.

[0041] Next, the effects of the above embodiment will be described below. (1) The electric wire 20 is doubly covered by the first metal braided member 21 and the metal pipe 22. Therefore, compared to when the electric wire 20 is covered only by the first metal braided member 21 or only by the metal pipe 22, for example, radiation of electromagnetic waves can be further suppressed.

[0042] (2) The length of the first metal braided member 21 in the direction in which the electric wire 20 extends is longer than the length of the electric wire 20 in the metal pipe 22 in the direction in which the electric wire 20 extends. As a result, the electric wire 20 in the metal pipe 22 is covered by the first metal braided member 21 in the entire area in the direction in which the electric wire 20 extends, and therefore, radiation of electromagnetic waves can be further suppressed in the entire area. In addition, the first metal braided member 21 extends to the outside of the metal pipe 22, which makes it easy to connect the first metal braided member 21 to other components, for example.

[0043] (3) The end of the first metal braided member 21 in the extension direction of the electric wire 20 has a folded-back portion 21a that is folded back at the end of the metal pipe 22 in the extension direction of the electric wire 20 and is connected to the outer circumferential surface of the metal pipe 22. This makes it possible to easily connect the first metal braided member 21 to the metal pipe 22 by the folded-back portion 21a.

[0044] (4) The outer surface of the metal pipe 22 has a painted portion 22a that is painted to indicate that it is for use with a high-voltage power line, and an unpainted portion 22b where the metal is exposed and to which the folded-back portion 21a is connected. As a result, the painted portion 22a indicates that it is for use with a high-voltage power line, and the unpainted portion 22b makes it easy to connect the folded-back portion 21a of the first metal braided member 21 to the metal pipe 22.

[0045] (5) The first metal braided member 21 is made of a copper-based metal material, and the metal pipe 22 is made of an iron-based metal material. Thus, because the first metal braided member 21 and the metal pipe 22 are made of different metal materials, radiation of electromagnetic waves in a wide frequency band can be suppressed. Furthermore, radiation of electromagnetic waves in a frequency band that would be of concern if, for example, the material of the body of the vehicle V in which the wire harness 10 is installed is replaced from a typical iron-based metal material to a carbon- or aluminum-based material can be suppressed. That is, if the material of the body of the vehicle V is replaced from a typical iron-based metal material to a carbon- or aluminum-based material, electromagnetic waves in a frequency band that were previously absorbed by the body may become less easily absorbed, raising concerns about the adverse effects of electromagnetic waves in that frequency band. In response to this, radiation of electromagnetic waves in that frequency band can be suppressed by the metal pipe 22 made of an iron-based metal material.

[0046] (6) The area of ​​the electric wire 20 covered by the second metal braided member 23 can suppress the radiation of electromagnetic waves. (7) Since the first metal braided member 21 and the second metal braided member 23 are provided with a crimping member 25 that connects and fixes them, the first metal braided member 21 and the second metal braided member 23 can be easily connected without performing complicated work such as welding.

[0047] (8) The folded portion 21a of the first metal braided member 21 and the covered portion 23a of the second metal braided member 23 are connected together to the metal pipe 22 by crimping and fixing the crimping member 25 to the metal pipe 22 as a base. This allows for a reduction in manufacturing steps and a simpler configuration compared to, for example, a configuration in which the first metal braided member 21, the second metal braided member 23, and the metal pipe 22 are connected at two or more locations.

[0048] (9) The waterproof member 26 can collectively prevent water from reaching the portion of the metal pipe 22 that comes into contact with the folded portion 21a, the folded portion 21a, the covering portion 23a, and the crimping member 25. In this embodiment, the first metal braided member 21 and the metal pipe 22 are made of different metal materials, but preventing them from being exposed to water prevents galvanic corrosion.

[0049] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. In the above embodiment, the length of the first metal braided member 21 in the extension direction is longer than the length of the metal pipe 22 in the extension direction, and the end of the first metal braided member 21 has the folded portion 21a that is folded back and connected to the outer surface of the metal pipe 22, but this is not limited to this.

[0050] For example, the length of the first metal braided member 21 in the extension direction may be shorter than the length of the metal pipe 22 in the extension direction. Also, for example, the end of the first metal braided member 21 may not have the folded-back portion 21a. For example, the first metal braided member 21 may be configured to be connected to the inner circumferential surface of the metal pipe 22.

[0051] In the above embodiment, the outer circumferential surface of the metal pipe 22 has the painted portion 22a and the unpainted portion 22b, but this is not limiting. For example, the metal pipe 22 may not have the painted portion 22a. Also, for example, the first metal braided member 21 may be connected to the inner circumferential surface of the metal pipe 22, and the outer circumferential surface of the metal pipe 22 may be entirely painted portion 22a without the unpainted portion 22b.

[0052] In the above embodiment, the first metal braided member 21 is made of a copper-based metal material, and the metal pipe 22 is made of an iron-based metal material, but they may be made of other metal materials. For example, the first metal braided member 21 may be made of an aluminum-based metal material containing aluminum as a main component. Also, for example, the first metal braided member 21 may be made of an iron-based metal material. Also, for example, the metal pipe 22 may be made of an aluminum-based metal material. Also, for example, the metal pipe 22 may be made of a copper-based metal material. The combination of metal materials making up the first metal braided member 21 and the metal pipe 22 may be changed in any way.

[0053] In the above embodiment, the wire harness 10 is configured to include the second metal braided member 23, but this is not limitative and the wire harness 10 may not include the second metal braided member 23. Also, in the above embodiment, the second metal braided member 23 is configured from a copper-based metal material, but this is not limitative and the wire harness 10 may be configured from another metal material. For example, the second metal braided member 23 may be configured from an aluminum-based metal material. Also, for example, the second metal braided member 23 may be configured from an iron-based metal material.

[0054] In the above embodiment, the wire harness 10 is configured to include the exterior member 24, but is not limited to this and may be configured to not include the exterior member 24. Also, in the above embodiment, the exterior member 24 is a corrugated tube, but is not limited to this and may be another exterior member.

[0055] In the above embodiment, the crimping member 25 is provided as a fixing member that connects and fixes the first metal braided member 21 and the second metal braided member 23, but this is not limited to this. For example, a C-shaped C-ring or a metal cable tie may be used as a fixing member that connects and fixes the first metal braided member 21 and the second metal braided member 23. Also, for example, the first metal braided member 21 and the second metal braided member 23 may be connected and fixed by welding without providing a fixing member such as the crimping member 25.

[0056] In the above embodiment, the crimping member 25 is crimped and fixed to the metal pipe 22 as a base, but this is not limited to this. For example, the crimping member 25 may be crimped and fixed to a base ring that is separate from the metal pipe 22.

[0057] In the above embodiment, the wire harness 10 includes the waterproof member 26, but this is not limiting and the wire harness 10 may be configured without the waterproof member 26. Furthermore, the waterproof member 26 may be changed to another configuration, such as a shrinkable tube, as long as it can collectively prevent the portion of the metal pipe 22 that comes into contact with the folded portion 21a, the folded portion 21a, the covering portion 23a, and the crimping member 25 from being wet.

[0058] In the above embodiment, the wire harness 10 has two electric wires 20, but this is not limited thereto, and the number of electric wires 20 included in the wire harness 10 may be one, or three or more.

[0059] In the above embodiment, the first metal braided member 21 covers two electric wires 20 together, but this is not limited thereto, and the first metal braided member 21 may cover each of the plurality of electric wires 20 individually. That is, the wire harness 10 may have a plurality of first metal braided members 21 according to the number of electric wires 20.

[0060] In the above embodiment, the second metal braided member 23 covers two electric wires 20 together, but this is not limited thereto, and the second metal braided member 23 may cover each of the plurality of electric wires 20 individually. That is, the wire harness 10 may have a plurality of second metal braided members 23 according to the number of electric wires 20.

[0061] In the above embodiment, the electric wire 20 is a high-voltage electric wire, but this is not limiting. For example, the electric wire 20 may be a low-voltage electric wire. In the above embodiment, the metal pipe 22 is arranged to pass under the floor of the vehicle V, but this is not limited to this and the metal pipe 22 may be arranged in another part of the vehicle V.

[0062] The phrase "at least one" used in this disclosure means "one or more" of the desired options. As an example, the phrase "at least one" used in this disclosure means "only one option" or "both of two options" when the number of options is two.
