It is comprised so that the state which applied damping | braking force to may be maintained.

  Also, in recent years, with advanced electronic control of vehicles, an ABS (Anti-lock Brake System) sensor that detects the rotational speed of a running wheel, a sensor such as an air pressure sensor that detects the air pressure of a tire, and a temperature sensor Species are often mounted on wheels.

  Therefore, using a composite cable in which a signal wire for a sensor mounted on a wheel and a signal wire for controlling an electric brake device and a power supply line for supplying electric power to the electric brake device are accommodated in a common sheath Connection with the vehicle body side is performed. Moreover, what provided the connector integrally at the edge part of this composite cable is called a composite harness.

  In the composite cable configured as described above, since the power supply line and the signal line are accommodated in the same sheath, electromagnetic noise may be generated due to the current flowing through the power supply line. Then, the composite cable using the signal wire | line coat | covered with the shield member as a countermeasure of this electromagnetic wave noise is proposed (for example, refer patent document 1).

  In FIG. 3, the end on the wheel 11 side is shown on the left side of the drawing, and the end on the relay box for front wheel 152 or the relay box for rear wheel 154 is shown on the right side of the drawing. In the following description, the end on the wheel 11 side of the wire harness 2 is referred to as "one end", and the end on the opposite side is referred to as "other end".

  The composite cable 2A transmits a pair of power lines 21 and 22 for supplying power to the electric brake device 12 to which power is supplied, and a signal (first electric signal) for controlling the electric brake device 12. A first shield wire 3, a second shield wire 4 transmitting a signal (second electrical signal) for detecting the wheel speed to detect the rotational speed of the wheel 11, a pair of power lines 21, 22 and a second A sheath 20 for covering the first and second shield wires 3 and 4 collectively and an inclusion 5 accommodated in the sheath 20 are provided. In the vehicle 1, the wheel 11 side and the vehicle body 10 side are connected by a composite cable 2A.

In addition, the wheel speed sensor 13 is attached to one end of the second shield wire 4 and the connection connector 43 for connection to the front wheel wire group 151 or the rear wheel wire group 153 is attached to the other end. It is done.

  The wire harness 2 is configured by a composite cable 2A, power connectors 23, 24, connection connectors 33, 34, 43, and a wheel speed sensor 13.

  The electric brake device 12 receives supply of power from the pair of power supply lines 21 and 22 and drives the caliper 121 to generate a braking force. In addition, whether the electric brake device 12 operates as an electromechanical brake (EMB) or an electric parking brake (EPB) based on a control signal transmitted from the control device 14 by the first shield wire 3 Switches. In addition, it is also possible to transmit the operation state of the electric brake device 12 to the control device 14 by the first shield wire 3.

  The electric signal output from the wheel speed sensor 13 is transmitted to the control device 14 by the second shield wire 4. When the control device 14 detects that the wheel 11 is locked based on the electric signal, the control device 14 reduces the braking force by the electric brake device 12 and releases the locked state of the wheel 11.

  The inclusions 5 are interposed between the pair of power supply lines 21 and 22 and the first and second shielded wires 3 and 4 inside the sheath 20. By the inclusions 5, the outer peripheral surface 20a (see FIG. 5A) of the sheath 20 in a cross section orthogonal to the central axis of the composite cable 2A is brought close to a circular shape, and the routeability of the composite cable 2A is enhanced.

  The sheath 20 is made of an insulating resin, and specifically, a flexible polyurethane excellent in flexibility and durability can be particularly preferably used as the material. As shown in FIG. 5A, when the outer diameter of the sheath 20 is D and the thickness is t, D is 8.0 to 10.0 mm and t is 1.0 to 2.0 mm.

The pair of power supply lines 21 and 22 is an insulated wire in which central conductors 210 and 220 each made of a conductive wire such as copper are covered with insulators 211 and 221 made of an insulating resin. The insulators 211 and 221 are made of, for example, crosslinked PE (polyethylene) or flame retardant crosslinked PE (polyethylene). Of the pair of power supply lines 21 and 22, the outer diameter of the central conductor 210 of one power supply line 21, the thickness of the insulator 211, and the outer diameter of the insulator 211 are the outer diameters of the central conductor 220 of the other power supply line 22. The diameter, the thickness of the insulator 221, and the outer diameter of the insulator 221 are the same. As shown in FIG. 5C, _{D 01} the outer diameter of the center conductor 210 of one power supply line 21, the thickness _{t 0} of the insulator 211, the outer diameter of the insulator 211 when the _{D 02, D 01} 1. 8~2.3mm, _{t 0} is _{0.3~0.5mm, D 02} is 2.9~3.1mm.

  The first shield wire 3 is formed by covering a first signal wire 30 made of a twisted pair wire with a first shield member 300. The second shield wire 4 is formed by covering the second signal wire 40 made of a twisted pair wire with the second shield member 400. The first shield member 300 is disposed in the outermost layer of the first shield wire 3, and the second shield member 400 is disposed in the outermost layer of the second shield wire 4. That is, in the present embodiment, the first shield member 300 and the second shield member 400 are not covered with an insulator or the like. Further, in the present embodiment, the first shield member 300 and the second shield member 400 are formed of a braided shield formed in a tubular shape by knitting a plurality of wire bundle. However, the first shield wire 3 and the second shield wire 4 are configured by spirally winding a strip-like shield member having conductivity around each of the first signal wire 30 and the second signal wire 40. It is also good.

  The first signal line 30 has a pair of insulated wires 31 and 32, and transmits signals for controlling the electric brake device 12 by the insulated wires 31 and 32. The signals transmitted by the pair of insulated wires 31 and 32 are differential signals whose phases are opposite to each other. The pair of insulated wires 31 and 32 is formed by covering the center conductors 310 and 320 with insulators 311 and 321 made of an insulating resin.

  The second signal line 40 is also configured similarly to the first signal line 30. That is, the second signal line 40 has a pair of insulated wires 41 and 42, and transmits the signals for detecting the wheel speed by the insulated wires 41 and 42. The signals transmitted by the pair of insulated wires 41 and 42 are differential signals whose phases are opposite to each other. The pair of insulated wires 41 and 42 is formed by covering the center conductors 410 and 420 with insulators 411 and 421 made of insulating resin.

The outer diameter of the central conductor 310 of one insulated wire 31 in the first signal line 30, the thickness of the insulator 311, and the outer diameter of the insulator 311, the outer diameter of the central conductor 320 of the other insulated wire 32, insulation The thickness of the body 321 and the outer diameter of the insulator 321 are common to each other. That is, one insulated wire 31 and 32 consists of common specifications. Assuming that the outer diameter of the central conductor 310 of one insulated wire 31 is D ₁₁ , the thickness of the insulator 311 is t ₁ , and the outer diameter of the insulator 311 is D ₁₂ as shown in FIG. 5B, D ₁₁ is 0. 6 to 0.9 mm, D ₁₂ is 1.3 to 1.6 mm, and t ₁ is 0.25 to 0.4 mm.

The outer diameter of the central conductor 410 of one insulated wire 41 in the second signal line 40, the thickness of the insulator 411, and the outer diameter of the insulator 411 and the outer diameter of the central conductor 420 of the other insulated wire 42, insulation The thickness of the body 421 and the outer diameter of the insulator 421 are common to each other. That is, one insulated wire 41 and 42 consists of common specifications. Assuming that the outer diameter of the central conductor 410 of one insulated wire 41 is D ₂₁ , the thickness of the insulator 411 is t − ₂ , and the outer diameter of the insulator 411 is D ₂₂ as shown in FIG. 5D, D ₂₁ is 0 7 to 1.0 mm, D ₂₂ is 1.4 to 1.8 mm, and t ₂ is 0.25 to 0.4 mm.

In the present embodiment, the outer diameter (thickness) D ₁₂ of the pair of insulated wires 31 and 32 of the first signal wire 30 and the outer diameter (thick) of the pair of insulated wires 41 and 42 of the second signal wire 40 ) And D ₂₂ are equivalent. _{Specifically,} the ratio of _{D 22} of _{D 12 (D 12 / D 22} ) is 0.8 to 1.2. _Furthermore, more desirable range of the ratio _(D 12 _/ D ₂₂₎ for _{D 22} of _{D 12} is 0.9 to 1.1.

  The first shield wire 3 and the second shield wire 4 are separated by a pair of power supply wires 21 and 22. In other words, the space in the sheath 20 is partitioned by the pair of power supply lines 21 and 22 into the accommodation space of the first shielded wire 3 and the accommodation space of the second shielded wire 4.

  Specifically, the distance between the pair of power supply wires 21 and 22 is the thickness of each of the pair of insulated wires 31 and 32 of the first shielded wire 3 and the pair of insulated wires of the second shielded wire 4 In order to prevent the first shield member 300 of the first shield wire 3 and the second shield member 400 of the second shield wire 4 from being in direct contact with each other, which is narrower than the respective thicknesses 41 and 42 It is done. In the example shown in FIG. 5A, since the pair of power supply lines 21 and 22 are in contact with each other, this interval is zero.

Further, as described above, the outer diameter D ₁₂ of the pair of insulated wires 31 and 32 of the first shield wire 3 and the outer diameter D ₂₂ of the pair of insulated wires 41 and 42 of the second shield wire 4 are equal. Therefore, in the arrangement direction of the first shield wire 3 and the second shield wire 4 in the cross section of the composite cable 2A, the pair of power supply wires 21 and 22 are located at the central portion of the sheath 20. The relative positional relationship between 22 and the first and second shield wires 3 and 4 is stabilized. Thereby, the above-mentioned effect becomes more remarkable.

Further, as shown in FIG. 5A, in the present embodiment, areas A ₁₁ and A ₁₂ surrounded by the pair of power supply lines 21 and 22, the first shield wire 3 and the second shield wire 4 are spaces. The inclusions 5 are not filled in the regions A ₁₁ and A ₁₂ . This facilitates the terminal processing of the composite cable 2A. That is, when terminating the composite cable 2A, a part of the sheath 20 is cut off to expose the pair of power supply lines 21 and 22, the first and second signal lines 30 and 40, and the inclusions 5 Furthermore, it is necessary to cut out the inclusions 5 exposed from the end of the sheath 20. At this time, if the inclusions 5 are filled in the regions A ₁₁ and A ₁₂ , the work to cut out the inclusions 5 is The pair of power supply lines 21 and 22 and the first and second shield wires 3 and 4 disturb each other, making it difficult. Therefore, in the present embodiment, the terminal processing of the composite cable 2A is facilitated by not filling the regions A ₁₁ and A ₁₂ with the inclusions 5.

As the inclusions 5, various fibrous materials such as polypropylene yarn, aramid fibers, nylon fibers, or fiber-based plastics generally used as inclusions of cables, paper, cotton yarn, etc. can be used. In the embodiment, the inclusions 5 contain the artificial polypeptide fiber. This artificial polypeptide fiber, also called spider silk fiber, is a artificial fiber containing a polypeptide derived from a natural spider silk protein as a main component, and has, for example, a stress of 350 to 628.7 MPa and a toughness of 138 to 265 .4 MJ / m ³ By including the artificial polypeptide fiber in the inclusions 5, the strength of the composite cable 2A can be enhanced.

  In addition, the sheath 20 may contain the above-mentioned artificial polypeptide fiber. Since the strength is enhanced by the inclusion of the artificial polypeptide fiber, the sheath 20 can be thinned, and the flexibility can be enhanced while the strength of the composite cable 2A is maintained, and the weight reduction can also be achieved.

  According to the embodiment described above, since the first shield wire 3 and the second shield wire 4 are separated by the pair of power supply wires 21 and 22, the first shield wire 3 is not The shield member 300 and the second shield member 400 of the second shield wire 4 do not come in direct contact with each other. Thereby, even if the composite cable 2A is repeatedly bent as the vehicle 1 travels, it is possible to suppress the wear of the first and second shield members 300 and 400. Therefore, the shield effect by the first and second shield members 300 and 400 is appropriately maintained, and the first shield wire 3 and the second shield wire 4 are generated by the electromagnetic noise due to the current flowing through the pair of power supply wires 21 and 22. It is suppressed that the transmission of the electrical signal via this is interrupted.

  Further, according to the above embodiment, since the covering layer made of an insulator or the like is not provided on the outside of the first shield member 300 and the second shield member 400, the first shield wire 3 and the second shield wire 3 are not provided. The diameter of the shield wire 4 can be reduced, and the diameter of the composite cable 2A can be reduced.
