[Explanation of Embodiments of the present disclosure]
First, the embodiments of the present disclosure will be listed and described.

[1] The wire harness of the present disclosure includes a first conductive path to which the first end is connected to a battery mounted on a vehicle, a distributor connected to the second end of the first conductive path, and the above. It has a plurality of connectors provided on the distributor, and a plurality of second conductive paths to which one end is connected to the connector and the electrical equipment is connected to the other end, and the distributor is connected to the battery. The electric power supplied through the first conductive path is distributed to the plurality of second conductive paths.

According to this configuration, the electric power supplied from the battery to the distributor through the first conductive path is distributed to the number of second conductive paths by the distributor. Therefore, the first conductive path connecting the battery and the distributor can be configured by a set of circuits including a positive wire and a negative wire. As a result, it is possible to prevent the structure of the first conductive path from becoming complicated. Therefore, as compared with the conventional wire harness, the assembling property of the wire harness to the vehicle can be improved.

Further, the second end of the first conductive path is connected to the distributor, and the second conductive path is connected to the connector provided in the distributor. Therefore, the first conductive path and the second conductive path can be separated. As a result, the first conductive path and the second conductive path can be separately assembled to the vehicle. Therefore, the assembling property of the wire harness to the vehicle can be improved as compared with the case where the first conductive path and the second conductive path are assembled to the vehicle together.

[2] It is preferable that the electric wires included in the first conductive path are only the positive side electric wire and the negative side electric wire constituting one set of circuits. According to this configuration, the electric wires of the first conductive path are only the positive side electric wires and the negative side electric wires constituting one set of circuits, so that compared with the case of having a plurality of sets of circuits. , The structure of the first conductive path can be simplified. As a result, the assembling property of the wire harness to the vehicle can be improved. Further, it is possible to improve the transportation efficiency of the wire harness (particularly, the first conductive path) before assembling to the vehicle.

[3] It is preferable that the conductor cross-sectional area of the electric wire possessed by the first conductive path is formed larger than the conductor cross-sectional area of the electric wire possessed by each of the second conductive paths. According to this configuration, a current larger than the current flowing through each of the second conductive paths can be passed through the first conductive path.

[4] The rigidity of the first conductive path is preferably higher than the rigidity of each of the second conductive paths. According to this configuration, the rigidity of the first conductive path is increased, so that the assembling property of the first conductive path to the vehicle can be improved. On the other hand, since the rigidity of the second conductive path is lowered, the second conductive path can be suitably connected to the electric device even when the space around the electric device is narrow. This makes it possible to improve the workability of connecting the second conductive path to the electric device.

[5] The distributor is fixed to the vehicle body of the vehicle. According to this configuration, even when the second conductive path is shaken due to vibration caused by an engine or the like, the swing is separated from the first conductive path by a distributor fixed to the vehicle body. be able to. As a result, it is possible to prevent the first conductive path from swinging. Therefore, the rigidity of the first conductive path can be set high.

[6] The distributor is provided at a boundary portion between the inside of the vehicle and the outside of the vehicle, and a connection portion between the distributor and the first conductive path is provided outside the vehicle interior, and the distributor and each of the second. The connection portion with the conductive path is provided in the vehicle interior. According to this configuration, the connecting portion between the distributor and the second conductive path can have a non-waterproof structure. Thereby, the structure of the connecting portion between the distributor and the second conductive path and the structure of the second conductive path can be simplified.

[7] The distributor has a metal housing, and the first conductive path has a plurality of electric wires and a metal metal pipe that collectively surrounds the outer periphery of the plurality of electric wires. , The metal pipe is electrically connected to the housing. According to this configuration, the metal housing and the metal pipe can function as the electromagnetic shield member.

[8] The metal pipe is connected to the housing by a conductive joining material so that the internal space of the metal pipe and the internal space of the housing communicate with each other, and the joining material is connected to the housing. The metal pipe and the housing are connected so that the internal space of the metal pipe and the internal space of the housing are in a waterproof state.

According to this configuration, the joining material that electrically connects the metal pipe and the housing functions as a waterproof member that keeps the internal space of the metal pipe and the internal space of the housing in a waterproof state. That is, the joining material can function as an electrical connection member and a waterproof member. As a result, the structure of the connecting portion between the metal pipe and the housing can be simplified as compared with the case where the electrical connecting member and the waterproof member are made of separate members.

[9] The plurality of second conductive paths have a conductive path connected to the inverter and a conductive path connected to an electric device other than the inverter. According to this configuration, a plurality of second conductive paths having a conductive path connected to the inverter and a conductive path connected to an electric device other than the inverter are electrically connected to the first conductive path via a distributor. Be connected.

(Overall configuration of wire harness 10)
The wire harness 10 shown in FIG. 1 is mounted on a vehicle V such as a hybrid vehicle or an electric vehicle, for example. The wire harness 10 electrically connects two or three or more electric devices (equipment). The wire harness 10 of the present embodiment electrically connects the high-voltage battery M1 and a plurality of electric devices M2, M3, M4, and M5.

The battery M1 is provided, for example, near the rear of the vehicle V. The battery M1 is fixed to the vehicle body of the vehicle V, for example. An example of the electric device M2 is an inverter installed in front of the vehicle V with respect to the battery M1. The battery M1 is, for example, a battery capable of supplying a voltage of 100 volts or more. The electric device M2 as an inverter is connected to, for example, a wheel drive motor (not shown) that is a power source for traveling the vehicle. The inverter (electrical device M2) generates AC power from the DC power from the battery M1 and supplies the AC power to the motor. The plurality of electric devices M3 to M5 are, for example, electric devices such as an air conditioner and a DC / DC converter. DC power is supplied from the battery M1 to the plurality of electric devices M3 to M5. In this way, DC power is distributed and supplied from the battery M1 to the plurality of electric devices M2 to M5. The electric devices M2 to M5 are provided in a vehicle interior such as an engine room, for example.

The wire harness 10 includes a conductive path 20 whose one end (here, the rear end) is connected to the battery M1, and a distributor 30 whose one end (here, the front end) is connected to the other end of the conductive path 20. It has a conductive path 50 that connects the distributor 30 and the electric device M2, and a conductive path 60 that connects the distributor 30 and the electric devices M3 to M5.

(Structure of Conductive Path 20)
The conductive path 20 electrically connects the battery M1 and the distributor 30. The conductive path 20 of the present embodiment constitutes a high voltage circuit that enables high voltage to be exchanged between the battery M1 and the distributor 30. The conductive path 20 is arranged from the battery M1 to the distributor 30 in such a manner that, for example, a part or all of the conductive path 20 passes under the floor of the vehicle V. That is, the conductive path 20 constitutes the lower part of the floor of the wire harness 10.

The conductive path 20 has one or a plurality of electric wires 21, a connector C1 attached to the rear end of the electric wire 21, and an exterior member 25 that surrounds the outer periphery of the electric wire 21. The rear end of the electric wire 21 is connected to the battery M1 via the connector C1, and the front end of the electric wire 21 is connected to the distributor 30. The electric wire 21 is, for example, a high-voltage electric wire that can handle high voltage and large current. The electric wire 21 may be, for example, a shielded electric wire having an electromagnetic shield structure by itself, or a non-shielded electric wire having no electromagnetic shield by itself. The electric wire 21 of this embodiment is a non-shielded electric wire.

As shown in FIG. 2, the electric wire 21 of the present embodiment has a positive electric wire 21A connected to the positive terminal of the battery M1 (see FIG. 1) and a negative electric wire 21B connected to the negative terminal of the battery M1. It has two high-voltage power lines. A set of circuits is composed of the positive side electric wire 21A and the negative side electric wire 21B.

(Composition of

electric wires

21A and 21B)
Each of the

electric wires

21A and 21B has a core wire 22 made of a conductor and an insulating coating 23 that covers the outer periphery of the core wire 22. The

electric wires

21A and 21B are formed in a long shape so as to extend in the front-rear direction of the vehicle, for example.

The core wire 22 includes, for example, a stranded wire formed by twisting a plurality of metal strands, a columnar conductor composed of one columnar metal rod having a solid structure inside, and a tubular conductor (pipe) having a hollow structure inside. Conductor) or the like can be used. As the columnar conductor, for example, a single core wire or a bass bar can be used. As the core wire 22, a stranded wire, a columnar conductor, or a tubular conductor may be used in combination. The core wire 22 of the present embodiment is a single core wire. As the material of the core wire 22, for example, a metal material such as copper-based or aluminum-based can be used. The core wire 22 is formed by, for example, extrusion molding.

The cross-sectional shape (that is, the cross-sectional shape) obtained by cutting the core wire 22 along a plane orthogonal to the length direction of the core wire 22 can be any shape. The cross-sectional shape of the core wire 22 can be any shape. The cross-sectional shape of the core wire 22 is formed, for example, into a circular shape, a semicircular shape, a polygonal shape, a square shape, or a flat shape. In the present specification, the "flat shape" includes, for example, a rectangle, an oval shape, an ellipse shape, and the like. The "rectangle" in the present specification has a long side and a short side, excluding a square. Further, the "rectangle" in the present specification includes a shape in which the ridge portion is chamfered and a shape in which the ridge portion is rounded. The "oval" in the present specification is a shape consisting of two parallel lines of substantially equal length and two semicircles. The cross-sectional shape of the core wire 22 of the present embodiment is formed in an oval shape.

The insulating coating 23 covers the outer peripheral surface of the core wire 22 over the entire circumference, for example. The insulating coating 23 covers, for example, the outer peripheral surface of the core wire 22 in close contact with the entire circumference. The outer peripheral surface of the insulating coating 23 is formed, for example, in a shape along the outer peripheral surface of the core wire 22. The insulating coating 23 of the present embodiment is formed in an oblong cylinder shape having an oval cross-sectional shape on the inner circumference and the outer circumference. The insulating coating 23 is made of an insulating material such as a synthetic resin.

The

electric wires

21A and 21B have rigidity that can maintain the shape along the arrangement path of the conductive path 20, for example. For example, the

electric wires

21A and 21B have such a rigidity that the linear or bent state is not released by the vibration of the vehicle V or the like when the

electric wires

21A and 21B are mounted on the vehicle V. In other words, the conductive path 20 may be configured to have or maintain one or more straight portions and one or more bent portions. As a result, it is possible to prevent the conductive path 20 from hanging down in the lower part of the floor or the like. Further, the configuration of the conductive path 20 having the above rigidity can improve the handleability of the conductive path 20 such as easy packing, easy transportation, and availability for automation of the assembly process to the vehicle V.

(Structure of exterior member 25)
The exterior member 25 has a long tubular shape as a whole. A plurality of

electric wires

21A and 21B are housed in the internal space S1 of the exterior member 25. The exterior member 25 is formed so as to surround the outer circumferences of the plurality of

electric wires

21A and 21B over the entire circumference. In the conductive path 20 of the present embodiment, only two

electric wires

21A and 21B are housed in the exterior member 25. There is a gap (space) between the radial inner surface of the exterior member 25 and the radial outer surface of each of the

electric wires

21A and 21B. In other words, the

wires

21A and 21B can be loosely housed in the exterior member 25 over the entire length of the

wires

21A and 21B. Of course, the

electric wires

21A and 21B may be in partial contact with the exterior member 25. The exterior member 25 protects the

electric wires

21A and 21B housed therein from flying objects and water droplets. As the exterior member 25, for example, a pipe made of metal or resin, a protector made of resin, a flexible corrugated tube made of resin or the like, a waterproof cover made of rubber, or a combination thereof can be used. ..

The exterior member 25 of this embodiment is a metal pipe. As the material of the metal pipe, for example, a metal material such as copper-based or aluminum-based can be used. The exterior member 25 made of such a metal pipe has a protective function of protecting the electric wire 21 from flying objects and the like, an electromagnetic shield function of protecting the electric wire 21 from electromagnetic waves, and a heat dissipation function of dissipating heat generated in the electric wire 21 and the like. have.

The exterior member 25 is, for example, a member having a higher bending rigidity than the electric wire 21. The exterior member 25 is more difficult to bend than, for example, the electric wire 21. The exterior member 25 of the present embodiment has rigidity that can maintain the path of the electric wire 21, for example. Such an exterior member 25 has a route regulating function that regulates the path of the electric wire 21 in addition to the above-mentioned protection function, electromagnetic shielding function, and heat dissipation function.

The cross-sectional shape of the exterior member 25 can be any shape. The cross-sectional shape of the exterior member 25 is formed, for example, into a circular shape, a semicircular shape, a polygonal shape, a square shape, or a flat shape. The cross-sectional shape of the exterior member 25 of the present embodiment is formed in a circular shape. That is, the exterior member 25 is formed in a cylindrical shape having a circular inner and outer cross-sectional shapes.

The exterior member 25 can be formed, for example, by extrusion molding. Such an exterior member 25 is formed, for example, in a shape having a constant cross-sectional shape over the entire length in the length direction.

As shown in FIG. 1, the conductive path 20 is arranged in, for example, a portion (for example, under the floor) where the arrangement of the wire harness 10 is easy and the shape needs to be maintained. Therefore, in the conductive path 20, it is preferable that at least one of the electric wire 21 and the exterior member 25 has a route regulating function. In the conductive path 20 of the present embodiment, both the electric wire 21 and the exterior member 25 have a route regulating function. Further, the conductive path 20 is arranged in a portion requiring waterproofing, for example. Therefore, in the conductive path 20, the accommodation space in which the

electric wires

21A and 21B are accommodated is configured as a closed space, and the inside of the accommodation space is maintained in a waterproof state (water-stopped state). For example, the connection portion between the connector C1 and the conductive path 20 shown in FIG. 1 and the connecting portion between the conductive path 20 and the distributor 30 have a waterproof structure such as a rubber waterproof cover.

One end (here, the front end) of the conductive path 20 is connected to the distributor 30. For example, the conductive path 20 and the distributor 30 are integrated. In other words, one end of the conductive path 20 is inseparably connected to, for example, the distributor 30. On the other hand, the conductive path 50 connected to the electric device M2 is connected to the distributor 30 by the connector C2. That is, the conductive path 50 is detachably connected to the distributor 30. Similarly, the conductive path 60 connected to each of the electric devices M3 to M5 is connected to the distributor 30 by the connector C3. That is, each conductive path 60 is detachably connected to the distributor 30.

The distributor 30 distributes the DC power supplied from the battery M1 to a plurality of electric devices M2 to M5. The distributor 30 is fixed to, for example, the vehicle body P1 of the vehicle V. The distributor 30 is fixed to, for example, the mounting surface P1a of the vehicle body P1. The distributor 30 is fixed to the mounting surface P1a by, for example, bolts (not shown).

The distributor 30 is provided, for example, at the boundary between the outside of the vehicle interior such as the lower floor and the interior of the engine room. For example, the connecting portion between the distributor 30 and the conductive path 20 is provided outside the vehicle interior, and the connecting portion between the distributor 30 and the

conductive paths

50 and 60 is provided inside the vehicle interior. Therefore, while the connection portion between the distributor 30 and the conductive path 20 needs to be waterproof, the connection portion between the distributor 30 and the

conductive paths

50 and 60 does not need to be waterproof. Therefore, it is not necessary to provide a waterproof structure at the connection portion between the distributor 30 and the

conductive paths

50 and 60.

(Structure of Conductive Path 50)
Next, the configuration of the conductive path 50 will be described.

The conductive path 50 electrically connects the distributor 30 and the electric device M2. The conductive path 50 of the present embodiment constitutes a high voltage circuit that enables high voltage to be exchanged between the distributor 30 and the electric device M2. The conductive path 50 is arranged from the distributor 30 to the electric device M2, for example. For example, the entire length of the conductive path 50 in the length direction is arranged in the vehicle interior such as an engine room.

The conductive path 50 has one or a plurality of electric wires 51, connectors C2 attached to both ends of the electric wire 51, and an exterior member 55 surrounding the outer periphery of the electric wire 51. One end of the electric wire 51 is connected to the electric device M2 via the connector C2, and the other end of the electric wire 51 is connected to the distributor 30 via the connector C2. The electric wire 51 is, for example, a high-voltage electric wire that can handle high voltage and large current. The electric wire 51 may be, for example, a shielded electric wire having an electromagnetic shield structure by itself, or a non-shielded electric wire having no electromagnetic shield by itself. The electric wire 51 of this embodiment is a non-shielded electric wire.

As shown in FIG. 3, the electric wire 51 of the present embodiment consists of a positive electric wire 51A connected to the positive terminal of the electric device M2 and a negative electric wire 51B connected to the negative terminal of the electric device M2. It has a book high-voltage power line.

(Composition of

electric wires

51A and 51B)
Each of the

electric wires

51A and 51B has a core wire 52 made of a conductor and an insulating coating 53 that covers the outer periphery of the core wire 52. The

electric wires

51A and 51B are formed in a long shape so as to extend in the front-rear direction of the vehicle, for example.

As the core wire 52, for example, a stranded wire, a columnar conductor, a tubular conductor, or a combination thereof can be used. The core wire 52 of this embodiment is a stranded wire. As the material of the core wire 52, for example, a metal material such as copper-based or aluminum-based can be used. The core wire 52 is formed by, for example, extrusion molding.

The cross-sectional area (that is, the cross-sectional area) of the core wire 52 is formed to be smaller than the cross-sectional area of the core wire 22 (see FIG. 2), for example. That is, the conductor cross-sectional area of the electric wire 51 of the conductive path 50 is formed to be smaller than the conductor cross-sectional area of the electric wire 21 of the conductive path 20 shown in FIG. The amount of current flowing through the core wire 52 is, for example, smaller than the amount of current flowing through the core wire 22.

The cross-sectional shape of the core wire 52 can be any shape. The cross-sectional shape of the core wire 52 is formed, for example, into a circular shape, a semicircular shape, a polygonal shape, a square shape, or a flat shape. The cross-sectional shape of the core wire 52 of the present embodiment is formed in a circular shape.

The insulating coating 53 covers the outer peripheral surface of the core wire 52 over the entire circumference, for example. The insulating coating 53 covers, for example, the outer peripheral surface of the core wire 52 in close contact with the entire circumference. The outer peripheral surface of the insulating coating 53 is formed, for example, in a shape along the outer peripheral surface of the core wire 52. The insulating coating 53 of the present embodiment is formed in a cylindrical shape having a circular inner and outer peripheral cross-sectional shapes. The insulating coating 53 is made of an insulating material such as a synthetic resin.

The electric wire 51 is more flexible than the electric wire 21, for example. For example, the electric wire 51 has a lower rigidity than the electric wire 21 and is easily bent. As a result, the workability of connecting the electric wire 51 to the electric device M2 and the distributor 30 can be improved.

(Structure of exterior member 55)
The exterior member 55 has a long tubular shape as a whole. A plurality of

electric wires

51A and 51B are housed in the internal space S2 of the exterior member 55. The exterior member 55 is formed so as to surround the outer circumferences of the plurality of

electric wires

51A and 51B over the entire circumference. In the conductive path 50 of the present embodiment, only two

electric wires

51A and 51B are housed in the exterior member 55 as electric wires. There is a gap (space) between the radial inner surface of the exterior member 55 and the radial outer surface of each of the

electric wires

51A and 51B. In other words, the

wires

51A and 51B can be loosely housed in the exterior member 55 over the entire length of the

wires

51A and 51B. Of course, the

electric wires

51A and 51B may be in partial contact with the exterior member 55. The exterior member 55 protects the

electric wires

51A and 51B housed therein from flying objects and the like. As the exterior member 55, for example, a pipe made of metal or resin, a protector made of resin, a flexible corrugated tube made of resin or the like, a waterproof cover made of rubber, or a combination thereof can be used. .. The exterior member 55 is preferably more flexible and flexible than the exterior member 25 (see FIG. 2), for example. The exterior member 55 of the present embodiment is a resin corrugated tube. As the material of the corrugated tube, for example, a resin material having conductivity or a resin material having no conductivity can be used. As the resin material, for example, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used.

The cross-sectional shape of the exterior member 55 can be any shape. The cross-sectional shape of the exterior member 55 is formed, for example, into a circular shape, a semicircular shape, a polygonal shape, a square shape, or a flat shape. The cross-sectional shape of the exterior member 55 of the present embodiment is formed in a circular shape. That is, the exterior member 55 is formed in a cylindrical shape having a circular inner and outer cross-sectional shapes.

The conductive path 50 has, for example, an electromagnetic shield member 56. The electromagnetic shield member 56 is formed so as to collectively surround the outer circumferences of the plurality of electric wires 51 in the internal space S2 of the exterior member 55, for example. The electromagnetic shield member 56 is provided, for example, between the inner peripheral surface of the exterior member 55 and the outer peripheral surface of the electric wire 51. As the electromagnetic shield member 56, for example, a flexible braided wire or a metal foil can be used. As the braided wire, a braided wire in which a plurality of metal strands are knitted or a braided wire in which a metal strand and a resin strand are combined can be used. As the material of the metal wire, for example, a metal material such as copper-based or aluminum-based can be used. As the resin wire, for example, reinforcing fibers having excellent insulating properties and shear resistance such as para-aramid fibers can be used. Although not shown, both ends of the electromagnetic shield member 56 are grounded (grounded) in the distributor 30 and the electric device M2 shown in FIG.

The conductive path 50 shown in FIG. 1 is superior in flexibility and flexibility to the conductive path 20. The conductive path 50 is arranged in, for example, a portion corresponding to the periphery of the electric device M2 in which the space is narrow and the arrangement is difficult in the arrangement path of the wire harness 10. The conductive path 50 is easily affected by vibration caused by, for example, an engine or the like, and is arranged in a swing section where swing occurs in the wire harness 10. At this time, since the conductive path 50 is excellent in flexibility, the conductive path 50 can absorb the fluctuation and prevent damage such as disconnection of the conductive path 50. Further, the conductive path 50 is arranged in a vehicle interior such as an engine room, and is arranged in a non-waterproof section that does not require waterproofing. Therefore, the conductive path 50 does not have to have a waterproof structure. For example, it is not necessary to provide a waterproof structure at the connection portion between the conductive path 50 and the distributor 30.

(Structure of Conductive Path 60)
Next, the configuration of each conductive path 60 will be described.

Each conductive path 60 electrically connects the distributor 30 and each of the electric devices M3 to M5. Each of the conductive paths 60 of the present embodiment constitutes a high voltage circuit that enables high voltage to be exchanged between the distributor 30 and the electric devices M3 to M5. Each conductive path 60 is arranged from the distributor 30 to each of the electric devices M3 to M5, for example. For example, the total length of each conductive path 60 in the length direction is arranged in a vehicle interior such as an engine room.

Each conductive path 60 has one or a plurality of electric wires 61, connectors C3 attached to both ends of the electric wire 61, and an exterior member 65 surrounding the outer periphery of the electric wire 61. One end of each electric wire 61 is connected to each of the electric devices M3 to M5 via the connector C3, and the other end of each electric wire 61 is connected to the distributor 30 via the connector C3. Each electric wire 61 is, for example, a high-voltage electric wire capable of dealing with a high voltage and a large current. The electric wire 61 may be, for example, a shielded electric wire having an electromagnetic shield structure by itself, or a non-shielded electric wire having no electromagnetic shield by itself. The electric wire 61 of this embodiment is a non-shielded electric wire.

As shown in FIG. 4, the electric wire 61 of the present embodiment has two high-voltage electric wires, a positive electric wire 61A and a negative electric wire 61B.

(Composition of

electric wires

61A and 61B)
Each of the

electric wires

61A and 61B has a core wire 62 made of a conductor and an insulating coating 63 that covers the outer periphery of the core wire 62. The

electric wires

61A and 61B are formed in a long shape so as to extend in the front-rear direction of the vehicle, for example.

As the core wire 62, for example, a stranded wire, a columnar conductor, a tubular conductor, or a combination thereof can be used. The core wire 62 of this embodiment is a stranded wire. As the material of the core wire 62, for example, a metal material such as copper-based or aluminum-based can be used. The core wire 62 is formed by, for example, extrusion molding.

The cross-sectional area of the core wire 62 is formed to be smaller than the cross-sectional area of the core wire 22 (see FIG. 2), for example. The cross-sectional area of the core wire 62 is formed to be smaller than the cross-sectional area of the core wire 52 (see FIG. 3), for example. That is, the conductor cross-sectional area of the electric wire 61 of the conductive path 60 shown in FIG. 1 is smaller than the conductor cross-sectional area of the electric wire 21 of the conductive path 20 and smaller than the conductor cross-sectional area of the electric wire 51 of the conductive path 50. .. The amount of current flowing through the core wire 62 is smaller than, for example, the amount of current flowing through the core wire 22. The amount of current flowing through the core wire 62 is smaller than, for example, the amount of current flowing through the core wire 52.

Here, the conductor cross-sectional area of the conductive paths 20 is formed so as to be equal to, for example, the total of the conductor cross-sectional areas of the

conductive paths

50 and 60, or larger than the total of the conductor cross-sectional areas of the

conductive paths

50 and 60. ..

The cross-sectional shape of the core wire 62 shown in FIG. 4 can be any shape. The cross-sectional shape of the core wire 62 is formed, for example, into a circular shape, a semicircular shape, a polygonal shape, a square shape, or a flat shape. The cross-sectional shape of the core wire 62 of the present embodiment is formed in a circular shape.

The insulating coating 63 covers the outer peripheral surface of the core wire 62 over the entire circumference, for example. The insulating coating 63, for example, covers the outer peripheral surface of the core wire 62 in close contact with the entire circumference. The outer peripheral surface of the insulating coating 63 is formed, for example, in a shape along the outer peripheral surface of the core wire 62. The insulating coating 63 of the present embodiment is formed in a cylindrical shape having a circular inner and outer peripheral cross-sectional shapes. The insulating coating 63 is made of an insulating material such as a synthetic resin.

The electric wire 61 is more flexible than the electric wire 21, for example. For example, the electric wire 61 has a lower rigidity than the electric wire 21 and is easily bent. As a result, the workability of connecting the electric wire 61 to the electric devices M3 to M5 and the distributor 30 can be improved.

(Structure of exterior member 65)
The exterior member 65 has a long tubular shape as a whole. A plurality of

electric wires

61A and 61B are housed in the internal space S3 of the exterior member 65. The exterior member 65 is formed so as to surround the outer circumferences of the plurality of

electric wires

61A and 61B over the entire circumference. In the conductive path 60 of the present embodiment, only two

electric wires

61A and 61B are housed in the exterior member 65. There is a gap (space) between the radial inner surface of the exterior member 65 and the radial outer surface of each of the

electric wires

61A and 61B. In other words, the

wires

61A and 61B can be loosely housed in the exterior member 65 over the entire length of the

wires

61A and 61B. Of course, the

electric wires

61A and 61B may be in partial contact with the exterior member 65. The exterior member 65 protects the

electric wires

61A and 61B housed therein from flying objects and the like. As the exterior member 65, for example, a pipe made of metal or resin, a protector made of resin, a flexible corrugated tube made of resin or the like, a waterproof cover made of rubber, or a combination thereof can be used. .. The exterior member 65 is preferably more flexible and flexible than the exterior member 25 (see FIG. 2), for example. The exterior member 65 of the present embodiment is a resin corrugated tube like the exterior member 55.

The cross-sectional shape of the exterior member 65 can be any shape. The cross-sectional shape of the exterior member 65 is formed, for example, into a circular shape, a semicircular shape, a polygonal shape, a square shape, or a flat shape. The cross-sectional shape of the exterior member 65 of the present embodiment is formed in a circular shape. That is, the exterior member 65 is formed in a cylindrical shape having a circular inner and outer cross-sectional shapes.

The conductive path 60 does not have, for example, an electromagnetic shield member. The conductive path 60 may have an electromagnetic shield member similar to the electromagnetic shield member 56 shown in FIG. The electromagnetic shield member in this case is formed so as to collectively surround the outer circumferences of the plurality of electric wires 61 in the internal space S3 of the exterior member 65, for example.

The conductive path 60 is superior in flexibility and flexibility to the conductive path 20. The conductive path 60 is arranged in, for example, a portion corresponding to the periphery of the electric devices M3 to M5 in which the space is narrow and the arrangement is difficult in the arrangement path of the wire harness 10. The conductive path 60 is easily affected by vibration caused by, for example, an engine or the like, and is arranged in a swing section where swing occurs in the wire harness 10. At this time, since the conductive path 60 is excellent in flexibility, the conductive path 60 can absorb the fluctuation and suppress damage such as disconnection of the conductive path 60. Further, the conductive path 60 is arranged in a vehicle interior such as an engine room, and is arranged in a non-waterproof section that does not require waterproofing. Therefore, the conductive path 60 does not have to have a waterproof structure. For example, it is not necessary to provide a waterproof structure at the connection portion between the conductive path 60 and the distributor 30.

The conductive path 20 is formed to have higher rigidity than, for example, the conductive path 50, and higher rigidity than each conductive path 60.

(Structure of distributor 30)
Next, the configuration of the distributor 30 will be described with reference to FIG. In FIG. 5, the exterior member 55 and the electromagnetic shield member 56 (see FIG. 3) in the conductive path 50 and the exterior member 65 (see FIG. 4) in the conductive path 60 are omitted for simplification of the drawings. doing.

The distributor 30 has, for example, a metal housing 31, a connector 32, a plurality of (here, three) connectors 33, a plurality of

bus bars

35 and 36, and a fuse 38. The housing 31 is fixed to the mounting surface P1a of the vehicle body P1 by, for example, bolts (not shown). The housing 31 is connected to the ground through, for example, the vehicle body P1.

The housing 31 has a wall portion 31A and an internal space S4 surrounded by the wall portion 31A. The wall portion 31A is formed with a through hole 31X that penetrates the wall portion 31A in the plate thickness direction. The through hole 31X is formed so that the internal space S4 communicates with the outside of the housing 31. The

connectors

32 and 33 are attached to the wall portion 31A. The connector C2 attached to the end of the electric wire 51 of the conductive path 50 is connected to the connector 32. That is, the electric wire 51 is connected to the connector 32 via the connector C2. A connector C3 attached to the end of the electric wire 61 of the conductive path 60 is connected to each connector 33. That is, the electric wire 61 is connected to each connector 33 via the connector C3. As the material of the housing 31 (wall portion 31A), for example, a metal material such as iron-based or aluminum-based can be used.

The front end portion of the exterior member 25 of the conductive path 20 is connected to the housing 31. The exterior member 25 is connected to the housing 31 so that the internal space S1 of the exterior member 25 communicates with the internal space S4 of the housing 31 through the through hole 31X. The exterior member 25 and the housing 31 are connected by, for example, a conductive joining material 28. The bonding material 28 is, for example, a brazing material. For example, the exterior member 25 as a metal pipe and the metal housing 31 are connected by brazing. The joining material 28, for example, connects the end portion of the exterior member 25 and the housing 31 without a gap. As a result, the internal space S1 of the exterior member 25 and the internal space S4 of the housing 31 are configured as a closed space, and the interior spaces S1 and S4 are kept in a waterproof state. Further, the exterior member 25 having an electromagnetic shield function is connected to the ground through the joining material 28, the housing 31, and the vehicle body P1. The method of connecting the exterior member 25 and the housing 31 is not limited to brazing, and may be, for example, welding or bolt fastening.

The ends (here, the front end) of the

electric wires

21A and 21B housed in the internal space S1 of the exterior member 25 project into the internal space S4 of the housing 31. At the ends of the

electric wires

21A and 21B, the insulating coating 23 is peeled off from the terminals of the

electric wires

21A and 21B over a predetermined length range, and the core wire 22 is exposed. The core wire 22 of the positive side electric wire 21A is electrically connected to the positive side bus bar 35. The core wire 22 of the electric wire 21B on the negative side is electrically connected to the bus bar 36 on the negative side. The connection method between the core wire 22 and the bus bars 35 and 36 can be performed by any method. In the present embodiment, the core wire 22 and the bus bars 35 and 36 are electrically connected by bolt fastening using the bolt B1.

(Composition of bus bars 35 and 36)
The bus bar 35 has a connection portion 35A extending from the connection portion connected to the core wire 22 of the positive wire 21A toward the connector 32 and a connection portion 35B extending from the connection portion with the core wire 22 toward the plurality of connectors 33. Have.

The connection portion 35A is connected to the connector 32. The connection portion 35A is electrically connected to the electric wire 51A of the conductive path 50 via the connector 32 and the connector C2. As a result, the positive side electric wire 51A of the conductive path 50 and the positive side electric wire 21A of the conductive path 20 are electrically connected via the connecting portion 35A.

The connection portion 35B has, for example, a plurality of (three in this case) branch portions 35C that branch from one trunk line portion and extend toward each connector 33. Each branch 35C is connected to the connector 33 via a fuse 38. Each branch portion 35C is electrically connected to the electric wire 61A of the conductive path 60 via the connector 33 and the connector C3. As a result, the positive side electric wire 61A of the conductive path 60 and the positive side electric wire 21A of the conductive path 20 are electrically connected via the connecting portion 35B.

The bus bar 36 has a connection portion 36A extending from the connection portion connected to the core wire 22 of the negative wire 21B toward the connector 32 and a connection portion 36B extending from the connection portion with the core wire 22 toward the plurality of connectors 33. Have.

The connection portion 36A is connected to the connector 32. The connecting portion 36A is electrically connected to the electric wire 51B of the conductive path 50 via the connector 32 and the connector C2. As a result, the electric wire 51B on the negative side of the conductive path 50 and the electric wire 21B on the negative side of the conductive path 20 are electrically connected via the connecting portion 36A.

The connection portion 36B has, for example, a plurality of (three in this case) branch portions 36C that branch from one trunk line portion and extend toward each connector 33. Each branch portion 36C is connected to the connector 33. Each branch portion 36C is electrically connected to the electric wire 61B of the conductive path 60 via the connector 33 and the connector C3. As a result, the electric wire 61B on the negative side of the conductive path 60 and the electric wire 21B on the negative side of the conductive path 20 are electrically connected via the connecting portion 36B.

As described above, the electric wire 21A of the conductive path 20 is electrically connected to the electric wire 51A of the conductive path 50 via the connecting portion 35A of the bus bar 35, and the three conductive lines are electrically connected via the connecting portion 35B of the bus bar 35. It is electrically connected to the electric wire 61A of the road 60. The electric wire 21B of the conductive path 20 is electrically connected to the electric wire 51B of the conductive path 50 via the connecting portion 36A of the bus bar 36, and is connected to the electric wire 61B of the three conductive paths 60 via the connecting portion 36B of the bus bar 36. It is electrically connected. As a result, the DC power supplied from the battery M1 (see FIG. 1) to the distributor 30 through the conductive path 20 is distributed to the conductive path 50 and the three conductive paths 60.

Next, the action and effect of this embodiment will be described.

(1) The wire harness 10 is provided in the conductive path 20 to which the rear end is connected to the battery M1 mounted on the vehicle V, the distributor 30 connected to the front end of the conductive path 20, and the distributor 30. It has a plurality of

connectors

32 and 33. The wire harness 10 has a conductive path 50 in which one end is connected to the connector 32 and the electric device M2 is connected to the other end, and one end is connected to each connector 33 and each electric device M3 to M5 is connected to the other end. Has a conductive path 60 to which is connected. The distributor 30 distributes the electric power supplied from the battery M1 through the conductive paths 20 to the plurality of

conductive paths

50 and 60.

According to this configuration, the electric power supplied from the battery M1 to the distributor 30 through the conductive paths 20 is distributed to the plurality of

conductive paths

50 and 60 by the distributor 30. Therefore, the conductive path 20 connecting the battery M1 and the distributor 30 can be configured by a set of circuits including the positive side electric wire 21A and the negative side electric wire 21B. As a result, it is possible to prevent the structure of the conductive path 20 from becoming complicated. Therefore, the assembling property of the wire harness 10 to the vehicle V can be improved as compared with the conventional wire harness.

(2) One end (here, the front end) of the conductive path 20 in the length direction is connected to the distributor 30, and the

conductive paths

50 and 60 are connected to the

connectors

32 and 33 provided in the distributor 30, respectively. Has been done. Therefore, the conductive paths 20 and the

conductive paths

50 and 60 can be separated. As a result, the conductive paths 20 and the

conductive paths

50 and 60 can be separately assembled to the vehicle V. For example, after the conductive path 20 and the distributor 30 are integrated and the integrated conductive path 20 and the distributor 30 are fixed to the vehicle body P1, the conductive path 50 is connected to the

connectors

32 and 33 of the distributor 30. , 60 are connected via connectors C2 and C3. Therefore, the assembling property of the wire harness 10 to the vehicle V can be improved as compared with the case where the conductive paths 20 and the

conductive paths

50 and 60 are assembled to the vehicle V together. Further, since the conductive paths 20 and the

conductive paths

50 and 60 can be transported separately, the transport efficiency of the wire harness 10 can be improved.

(3) Since the conductive path 20 and the

conductive paths

50 and 60 can be separated, the conductor cross-sectional area of the conductive path 20 and the conductor cross-sectional area of the

conductive paths

50 and 60 can be set individually. Further, the electromagnetic shield structure in the conductive paths 20 and the electromagnetic shield structure in the

conductive paths

50 and 60 can be individually set.

(4) The electric wires 21 included in the conductive path 20 are only the positive side electric wires 21A and the negative side electric wires 21B constituting one set of circuits. According to this configuration, the structure of the conductive path 20 can be simplified as compared with the case where the electric wires constituting a plurality of sets of circuits are provided. Thereby, the assembling property of the wire harness 10 to the vehicle V can be improved. It is also possible to improve the transportation efficiency of the wire harness 10 before assembling it to the vehicle V.

(5) In the conductive path 20, only the positive side electric wire 21A and the negative side electric wire 21B constituting one set of circuits are housed in the exterior member 25. Therefore, wasted space is less likely to occur in the exterior member 25. As a result, the conductive path 20 can be miniaturized.

(6) The rigidity of the conductive paths 20 is formed higher than the rigidity of the

conductive paths

50 and 60, respectively. According to this configuration, the rigidity of the conductive path 20 is increased, so that the assembling property of the conductive path 20 with respect to the vehicle V can be improved.

(7) When the rigidity of the conductive path 20 is increased, the handleability of the conductive path 20 by a robot hand or the like is improved. Therefore, it becomes easy to automate the process of assembling the conductive path 20 to the vehicle V.

(8) The flexibility of each of the

conductive paths

50 and 60 was formed higher than the flexibility of the conductive paths 20. According to this configuration, even when the space around the electric devices M2 to M5 is narrow, the

conductive paths

50 and 60 can be suitably connected to the electric devices M2 to M5. As a result, the workability of connecting the

conductive paths

50 and 60 to the electric devices M2 to M5 can be improved.

(9) The distributor 30 is fixed to the vehicle body P1 of the vehicle V. According to this configuration, even when the

conductive paths

50 and 60 swing due to vibration caused by, for example, an engine or the like, the swing is caused by the distributor 30 fixed to the vehicle body P1 to the conductive path 20. Can be separated. As a result, it is possible to prevent the conductive path 20 from swinging. Therefore, the rigidity of the conductive path 20 can be set high.

(10) The distributor 30 is provided at the boundary between the inside of the vehicle and the outside of the vehicle. The connecting portion between the distributor 30 and the conductive path 20 is provided outside the vehicle interior, and the connecting portion between the distributor 30 and the

conductive paths

50 and 60 is provided inside the vehicle interior. According to this configuration, the connecting portion between the distributor 30 and the

conductive paths

50 and 60 can have a non-waterproof structure. Thereby, the structure of the connecting portion between the distributor 30 and the

conductive paths

50 and 60 can be simplified.
