[Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

(Description of the vehicle to which the wire harness is applied)
FIG. 1 is a schematic view showing a configuration of a vehicle in which the wire harness according to the present embodiment is used.

The vehicle 1 has four tire houses 100 in the vehicle body 10, and two front wheels 11 and two rear wheels 12 are arranged in each tire house 100. In the present embodiment, the vehicle 1 is a front-wheel drive vehicle, and the front wheels 11 are driven by receiving the driving force of a drive source (not shown) including an engine and an electric motor. That is, in the present embodiment, the front wheels 11 are the driving wheels and the rear wheels 12 are the driven wheels.

Further, the vehicle 1 has two electric parking brake devices 130 and a control device 14. The electric parking brake device 130 is provided corresponding to each of the two rear wheels 12 and operates by the current supplied from the control device 14 to generate a braking force on the rear wheels 12. The control device 14 can detect the operating state of the parking brake operating switch 140 provided in the vehicle interior, and the driver can turn the parking brake operating switch 140 on / off to turn on / off the parking brake operating switch 140, whereby the electric parking brake device 130 can be operated. It is possible to switch between the activated state and the non-operated state.

For example, when the driver turns the parking brake operation switch 140 from the off state to the on state while the vehicle is stopped, the control device 14 outputs an operating current for operating the electric parking brake device 130 for a predetermined time (for example, 1 second). do. As a result, the electric parking brake device 130 operates to generate a braking force on the rear wheels 12. The operating state of the electric parking brake device 130 is maintained until a current for deactivating the electric parking brake device 130 is output from the control device 14. As described above, the electric parking brake device 130 mainly generates a braking force after the vehicle 1 is stopped.

The control device 14 outputs a current for deactivating the electric parking brake device 130 when the parking brake operation switch 140 is turned from the on state to the off state by the operation of the driver. The control device 14 outputs a current for deactivating the electric parking brake device 130 not only when the parking brake operation switch 140 is turned off but also when the accelerator pedal is depressed, for example. do.

Further, the front wheels 11 and the rear wheels 12 are provided with a wheel speed sensor (ABS sensor) 131 for detecting the wheel speed. The wheel speed sensor 131 itself is well known and has a magnetic field detection element that detects the magnetic field of an annular magnetic encoder that rotates with the front wheels 11 or the rear wheels 12, and the wheels are changed by a cycle in which the direction of the magnetic field changes. The speed (rotational speed of the front wheel 11 or the rear wheel 12) is detected.

The control device 14 and the wheel speed sensor 131 of the front wheels 11 are electrically connected by a front wheel electric wire group 151 composed of a plurality of electric wires and a front wheel wire harness 152. The front wheel electric wire group 151 and the front wheel wire harness 152 are connected in a relay box 153 fixed to the vehicle body 10. The relay box 153 is arranged in the vicinity of each of the pair of left and right front wheels 11.

Further, the control device 14, the electric parking brake device 130 of the rear wheels 12, and the wheel speed sensor 131 are electrically connected by a rear wheel electric wire group 154 composed of a plurality of electric wires and a wire harness 2 according to the present embodiment. It is connected. The rear wheel electric wire group 154 and the wire harness 2 are connected in a relay box 155 fixed to the vehicle body 10. The relay box 155 is arranged in the vicinity of each of the pair of left and right rear wheels 12.

The front wheel electric wire group 151 is arranged in a wiring path 150 provided in the vehicle body 10 in a bundled state. Further, the rear wheel electric wire group 154 is also arranged in the wiring path 150 provided in the vehicle body 10 in a bundled state, like the front wheel electric wire group 151.

One end of the front wheel wire harness 152 is connected to the wheel speed sensor 131 of the front wheel 11, and the other end is housed in the relay box 153. One end of the rear wheel wire harness 2 is connected to the electric parking brake device 130 and the wheel speed sensor 131 of the rear wheel 12, and the other end is housed in the relay box 155.

(Explanation of cable used for wire harness 2)
FIG. 2 is a cross-sectional view of the cable 3 used for the wire harness 2. The cable 3 is configured by collectively covering a plurality of electric wires 30 with a sheath 33. In the present embodiment, the plurality of electric wires 30 are composed of a pair of power supply lines 31 and a pair of signal lines 32, for a total of four insulated wires.

More specifically, in cable 3, the pair of signal lines 32 are twisted together. In the cable 3, a pair of twisted signal lines 32, a pair of power supply lines 31, and an interposition 34 are twisted together, and a presser winding tape 35 is spirally wound around the pair of signal lines 32. The outer circumference of the presser winding tape 35 is covered with a sheath 33.

A first power connector (not shown) for connecting to the electric parking brake device 130 is attached to one end of the pair of power lines 31, and the other end of the pair of power lines 31 is inside the relay box 155. A second power connector (not shown) for connection with the rear wheel electric wire group 154 is attached.

A wheel speed sensor 131 is attached to one end of the pair of signal lines 32, and a signal line connection connector (not shown) for connecting to the rear wheel electric wire group 154 in the relay box 155 is attached to the other end. It is attached.

The pair of power lines 31 are used to supply current to the electric parking brake device 130. The pair of signal lines 32 are used to transmit the detection signal of the wheel speed sensor 131 to the control device 14. That is, when the vehicle 1 is traveling, the pair of signal lines 32 transmit a detection signal of the vehicle state amount indicating the traveling state of the vehicle 1 to the control device 14.

The pair of power lines 31 are insulated wires in which a central conductor 310 made of a good conductive lead wire such as copper is coated with an insulator 311 made of an insulating resin. The center conductor 310 is a stranded wire composed of a plurality of strands. The insulator 311 is made of, for example, cross-linked PE (polyethylene) or flame-retardant cross-linked PE (polyethylene).

The signal line 32 is an insulated wire in which a central conductor 320 made of a good conductive conducting wire such as copper is coated with an insulator 321 made of an insulating resin. The center conductor 320 is a stranded wire composed of a plurality of strands. The insulator 321 is made of, for example, cross-linked PE (polyethylene) or flame-retardant cross-linked PE (polyethylene). The outer diameter of the signal line 32 is smaller than the outer diameter of the power supply line 31. As described above, in the present embodiment, the cable 3 includes the electric wires 30 having different outer diameters.

The power line 31 and the signal line 32 are not covered with a shield conductor. That is, no conductive member that shields electromagnetic waves is arranged between the power line 31 and the signal line 32. This is because the current flows through the power supply line 31 mainly when the vehicle 1 is stopped, and the signal line 32 transmits the electric signal mainly when the vehicle 1 is running. Therefore, the signal line 32 and the power supply line 31 It is noted that it is not necessary to provide a shield conductor between them. That is, when a current flows through the pair of power supply lines 31, the electromagnetic wave generated by this current may affect the potential difference between the pair of signal lines 32, but the control device 14 stops the vehicle 1 having a vehicle speed of zero. In some cases, the electric signal of the signal line 32 can be ignored so as not to adversely affect the traveling of the vehicle 1. Further, since the signal line 32 is not covered with the shield conductor, the flexibility of the cable 3 is increased, the flexibility is increased, and the weight and cost of the cable 3 can be reduced.

The sheath 33 is made of an insulating resin. In this embodiment, the sheath 33 is made of a soft thermoplastic urethane having excellent flexibility and durability.

(Structure of branch part)
FIG. 3A is a plan view showing a branch portion of the wire harness 2, and FIG. 3B is a perspective view of the fixing member thereof. As shown in FIG. 3, in the wire harness 2 according to the present embodiment, the cable 3 has a branch portion 3a for branching a plurality of electric wires 30 extending from the sheath 33. In the present embodiment, the branch portion 3a is configured to branch the pair of power supply lines 31 and the pair of signal lines 32.

The wire harness 2 is formed so as to cover the end of the sheath 33 and the plurality of electric wires 30 extending from the ends of the sheath 33, and the electric wire fixing portion 4 for fixing the extending direction of the plurality of electric wires 30. And a fixing member 5 for fixing the cable 3 to the object to be fixed such as the vehicle body 10.

The electric wire fixing portion 4 is formed so as to cover the branch portion 3a, and plays a role of fixing the extending direction of each electric wire 30 and a role of suppressing the infiltration of water into the sheath 33. .. Hereinafter, the electric wire 30 in the portion near the end of the sheath 33 is referred to as an extension portion of the electric wire 30. In the present embodiment, the electric wire fixing portion 4 is formed in a substantially rectangular parallelepiped shape, but the specific shape of the electric wire fixing portion 4 is not limited to this. For example, the electric wire fixing portion 4 may be formed in a substantially columnar shape or the like.

The electric wire fixing portion 4 is formed by a resin mold. As the electric wire fixing portion 4, a material made of thermoplastic urethane, which is the same resin material as the sheath 33, was used. As a result, when the electric wire fixing portion 4 is molded with resin, the electric wire fixing portion 4 and the sheath 33 are melt-integrated (welded), and moisture is suppressed from entering the sheath 33 to improve waterproofness. Further, by welding the electric wire fixing portion 4 and the sheath 33, it is possible to prevent the electric wire fixing portion 4 from moving in the longitudinal direction of the cable 3.

In the present embodiment, the extending direction of the pair of power lines 31 from the wire fixing portion 4 is parallel to the longitudinal direction of the sheath 33 in the wire fixing portion 4. Further, the extending direction of the pair of signal lines 32 from the electric wire fixing portion 4 is inclined (crossed) with respect to the extending direction of the pair of power supply lines 31 from the electric wire fixing portion 4. The pair of signal lines 32 are bent in the wire fixing portion 4 according to the angle of inclination. The inclination in the extending direction facilitates the wiring of the pair of power supply lines 31 and the pair of signal lines 32 in the tire house 100 of the vehicle 1. Here, the extending direction of the pair of signal lines 32 from the electric wire fixing portion 4 is the direction perpendicular to the extending direction of the pair of power supply lines 31 from the electric wire fixing portion 4.

In the present embodiment, the electric wire fixing portion 4 is formed so as to cover a part of the fixing member 5 together with the branch portion 3a of the cable 3, whereby the fixing member 5 is integrally provided with the electric wire fixing portion 4. ing. That is, the fixing member 5 is inserted at the time of resin molding of the electric wire fixing portion 4, and a part thereof is embedded in the resin together with the branch portion 3a. This eliminates the need to separately perform the work of providing the fixing member 5 after the resin molding, and makes it possible to improve the workability of the wire harness 2 assembly work.

The fixing member 5 connects the anchor portion 51 embedded in the electric wire fixing portion 4, the fixing portion 53 arranged outside the electric wire fixing portion 4 and fixed to the object to be fixed, and the anchor portion 51 and the fixing portion 53. It has a part 52 and. In the present embodiment, the anchor portion 51 is formed in a plate shape. The connecting portion 52 is formed in the shape of a cylindrical rod, and is formed so as to extend from the anchor portion 51 in a direction orthogonal to the anchor portion 51 (normal direction with respect to the surface of the anchor portion 51). A part of the connecting portion 52 on the anchor portion 51 side is embedded in the electric wire fixing portion 4. The width of the anchor portion 51 is larger than that of the connecting portion 52 in the plan view in FIG. 3A. As a result, the fixing member 5 is prevented from coming off from the electric wire fixing portion 4.

The fixed portion 53 is formed in a conical shape coaxial with the connecting portion 52, and is formed (tapered) so that the diameter is reduced as the distance from the connecting portion 52 increases. The connecting portion 52 is inserted into a locking groove (not shown) provided in the object to be fixed, and the fixing portion 53 (more specifically, the stepped portion between the fixing portion 53 and the connecting portion 52) is placed on the peripheral edge of the locking groove. By locking, the fixing member 5 is locked to the object to be fixed, and the electric wire fixing portion 4 and the cable 3 are fixed to the object to be fixed via the fixing member 5. As the fixing member 5, depending on the intended use, a resin made of a resin that can be manufactured at a relatively low cost may be used, or a metal having high mechanical strength may be used. Further, as the fixing member 5, a metal coated with a resin can also be used. The fixing member 5 and the electric wire fixing portion 4 do not have to be melt-integrated (welded) with each other.

It is desirable that the fixing member 5 is provided so as to be separated from the end portion of the sheath 33. This is because if the fixing member 5 is provided in contact with the end portion of the sheath 33, moisture may enter the sheath 33 through the fixing member 5. By providing the fixing member 5 apart from the end portion of the sheath 33, the end portion of the sheath 33 is in a state of being melt-integrated with the electric wire fixing portion 4, and moisture penetrates into the sheath 33 through the fixing member 5. It is suppressed that it is stored.

In the present embodiment, the fixing member 5 is provided apart from the sheath 33. Here, the anchor portion 51 of the fixing member 5 is provided apart from the sheath 33, and the connecting portion 52 (and the fixing portion 53) is provided so as to extend from the anchor portion 51 to the opposite side of the sheath 33. .. As a result, the resin enters between the sheath 33 and the fixing member 5, and the sheath 33 and the electric wire fixing portion 4 are welded over a long range in the longitudinal direction of the cable. As a result, even if the length of the wire fixing portion 4 along the cable longitudinal direction is shortened, sufficient waterproofness can be ensured and the movement of the wire fixing portion 4 along the cable longitudinal direction can be suppressed, and the wire fixing portion 4 can be suppressed. Can be miniaturized (miniaturization in the longitudinal direction of the cable). By making the wire fixing portion 4 small, the amount of the resin material used can be reduced to reduce the cost, and the wire harness 2 can be easily arranged.

(Actions and effects of embodiments)
As described above, in the wire harness 2 according to the present embodiment, the electric wire fixing portion 4 is formed by a resin mold, and is formed so as to cover a part of the fixing member 5 together with the cable 3 and is fixed. The member 5 is integrally provided with the wire fixing portion 4. In other words, in the present embodiment, a part of the fixing member 5 is embedded and integrated in the electric wire fixing portion 4 made of a resin mold.

As a result, it is possible to omit the step of separately attaching the fixing member 5 after forming the electric wire fixing portion 4 by the resin mold, and it is possible to improve the workability of the wire harness assembly work.

(Other embodiments)
FIG. 4A is a plan view showing a branch portion 3a of the wire harness 2a according to another embodiment of the present invention, and FIG. 4B is a perspective view of the fixing member 5a thereof. The wire harness 2a uses the fixing member 5a having a different shape of the anchor portion 51 in the above-mentioned wire harness 2.

In the wire harness 2a, the anchor portion 51 is configured to grip the sheath 33. The anchor portion 51 is formed in an arc shape along the outer periphery of the sheath 33. The fixing member 5a is fixed to the cable 3 by gripping the anchor portion 51. This makes it possible to prevent the fixing member 5a from moving (misalignment occurs) due to the flow of the resin during resin molding. Further, in this form, it is possible to reduce the need to provide a structure for fixing the fixing member 5a to the mold used for the resin mold. As a result, it becomes possible to simplify the shape of the mold, reduce the cost of the mold, and extend the life of the mold.

In the wire harness 2a, the inner peripheral surface of the anchor portion 51 is in contact with the outer peripheral surface of the sheath 33. Therefore, the sheath 33 is provided so as to extend from the anchor portion 51 to the extension side of the plurality of electric wires 30. That is, the anchor portion 51 is separated from the end portion of the sheath 33 on the branch portion 3a side. As a result, the end portion of the sheath 33 between the end portion on the branch portion 3a side of the sheath 33 and the anchor portion 51 can be melt-integrated (welded) with the electric wire fixing portion 4, and is transmitted through the fixing member 5a. It is preferable to prevent water from entering the sheath 33.

The wire harness 2b shown in FIGS. 5A and 5B uses a fixing member 5b made of a fixing bracket obtained by bending a metal plate. In the fixing member 5b, the anchor portion 51 is formed by bending one end of the metal plate in an arc shape along the outer diameter of the sheath 33. Further, the fixing portion 53 is formed by forming a bolt hole 54 for fixing the bolt at the other end portion of the metal plate. The intermediate portion between the anchor portion 51 and the fixing portion 53 on the metal plate serves as the connecting portion 52. By using the metal fixing member 5b, the mechanical strength of the fixing member 5b can be further improved, and the cable 3 and the electric wire fixing portion 4 can be more firmly fixed to the object to be fixed.

The wire harness 2c shown in FIG. 6 is provided with a heat shrink tube 6 so as to cover the end portion of the sheath 33 and the extension portions of the plurality of electric wires 30. As the heat-shrinkable tube 6, a heat-shrinkable tube with an adhesive provided with an adhesive layer made of a hot-melt adhesive on the inner peripheral surface of the heat-shrinkable resin tube is used. The resin tube is made of, for example, polyethylene, and the hot melt adhesive constituting the adhesive layer is made of, for example, polyamide and polyethylene.

The hot-melt adhesive constituting the adhesive layer melts due to the heat generated when the heat-shrinkable tube 6 is shrunk, enters the gap between the resin tube, the power supply line 31, the signal line 32, and the sheath 33, and cures after shrinking. The gap between the resin tube, the power supply line 31, the signal line 32, and the sheath 33 is sealed. As a result, it is possible to more reliably suppress the intrusion of water into the sheath 33.

Here, since the 4-core cable 3 having the pair of power lines 31 and the pair of signal lines 32 is used, the gap between the wires is larger than that of, for example, a 2-core cable or the like. Therefore, in the present embodiment, an adhesive is separately added in addition to the adhesive layer of the heat-shrinkable tube 6 so that the gap between the electric wires 30 can be reliably sealed. As the adhesive to be added, for example, an adhesive that is formed in an annular shape and can be arranged so as to surround the circumference of each electric wire 30 can be used. This annular adhesive melts due to the heat generated when the heat-shrinkable tube 6 is shrunk, and seals the space inside the resin tube. As the annular adhesive, one having the same composition as the adhesive layer of the heat-shrinkable tube 6 may be used, and one made of polyamide and polyethylene can be used.

When the heat-shrinkable tube 6 is used, the anchor portion 51 of the fixing member 5b is configured to fix the heat-shrinkable tube 6 to the sheath 33 by pressing the heat-shrinkable tube 6 of the portion covering the sheath 33 toward the sheath 33 side. Is desirable. This makes it possible to suppress the displacement of the heat-shrinkable tube 6 at a high temperature and prevent the heat-shrinkable tube 6 from falling off from the sheath 33 and reducing the waterproof property.

The wire harness 2d shown in FIGS. 7 (a) and 7 (b) is the wire harness 2b of FIG. 5 in which the fixing member 5b is attached to the pair of power lines 31. In this case, the anchor portion 51 has an elliptical shape (rounded rectangle) that collectively covers the periphery of the pair of power supply lines 31 arranged side by side by bending one end of the metal plate. Shape) or oval shape. As described above, the anchor portion 51 may be configured not only to grip the sheath 33 but also to grip a part or all of the plurality of electric wires 30.
