[0019] [Implementation Method]

[0020] Figure 1 1 is a schematic structural diagram showing a structural example of a vehicle 100 equipped with a wire harness 1 according to an embodiment of the present invention. A wheel 11 having a wheel 111 and a tire 112 of the vehicle 100 is supported on a vehicle body 10 via a suspension device 12. The suspension device 12 is configured to include an upper arm 121, a lower arm 122, a shock absorber 123, and a suspension spring 124. One end of each of the upper arm 121 and the lower arm 122 is connected to a steering knuckle 13, and the other end is connected to the vehicle body 10.

[0021] The knuckle 13 has a first connection portion 131 connecting the upper arm 121 and the shock absorber 123, a second connection portion 132 connecting the lower arm 122, and a mounting portion 133 for mounting the electric brake unit 16. In addition, the outer ring 141 of the hub unit 14 that rotatably supports the wheel 11 is fixed to the knuckle 13.

[0022] The hub unit 14 has an outer ring 141 and a hub ring 142 supported to rotate freely relative to the outer ring 141. A plurality of rolling elements (not shown) are arranged between the inner peripheral surface of the outer ring 141 and the outer peripheral surface of the hub ring 142 and are held by a retainer. A wheel mounting flange 142a is provided on the hub ring 142, and the wheel 111 is mounted on the wheel mounting flange 142a together with the brake disc 15 by a plurality of hub bolts 143. The brake disc 15 integrally has a friction portion 151 that frictionally slides with the brake pads 161 and 162 of the electric brake unit 16 and a fixing portion 152 fixed to the wheel mounting flange 142a of the hub ring 142.

[0023] A wheel speed sensor 7 is mounted on the outer ring 141 of the hub unit 14. The wheel speed sensor 7 detects the rotation speed of the hub ring 142 relative to the outer ring 141 as the rotation speed of the wheel 11. Specifically, a magnetic field detection element such as a Hall IC is used to detect changes in the magnetic field of a magnetic encoder mounted on the hub ring 142, and a pulse signal with a pulse interval corresponding to the rotation speed of the hub ring 142 relative to the outer ring 141 is output as a detection signal.

[0024] The electric brake unit 16 includes an outer brake pad 161 and an inner brake pad 162, a brake caliper 163 to which the outer brake pad 161 is mounted, a piston 164 to which the inner brake pad 162 is mounted, and a brake caliper bracket 165 fixed to the mounting portion 133 of the steering knuckle 13. The brake caliper 163 is supported by the brake caliper bracket 165 and can move parallel to the rotation axis of the wheel 11.

[0025] The vehicle 100 includes a brake controller 8 for controlling the electric brake unit 16 and a master controller 9 for comprehensively controlling the vehicle 100. The brake controller 8 and the wheel speed sensor 7 are arranged on the wheel side, and move in the up-down direction relative to the vehicle body 10 together with the wheel 11 as the suspension spring 124 expands and contracts. The master controller 9 is arranged on the vehicle body side. The brake controller 8 is one form of the "wheel side control device" of the present invention, and the master controller 9 is one form of the "vehicle side control device" of the present invention.

[0026] The wire harness 1 connects the brake controller 8, the wheel speed sensor 7, and the main controller 9. Next, the structure of the wire harness 1 will be described in detail.

[0027] Figure 2 (a) Yes Figure 1 A partial enlarged view of . Figure 2 (b) is represented by a two-dot chain line. Figure 2 (a) is an explanatory diagram of the cover member 5 of the wire harness 1, in which the inside of the cover member 5 is indicated by solid lines.

[0028] Figure 3 This is a structural diagram of the wiring harness 1. Figure 4 (a) Yes Figure 3 Cross-sectional view along line AA. Figure 4 (b) Yes Figure 3 Cross-sectional view of line BB. Figure 4 (c) Yes Figure 3 Cross-sectional view of the CC line. Figure 5 It is a perspective view showing the cover member 5 as a single body.

[0029] The wiring harness 1 comprises: a first connector 21, which can be detachably mounted on the brake controller 8; a second connector 22, which can be detachably mounted on the integrated controller 9; a trunk cable 3, which is located between the first connector 21 and the second connector 22; a branch cable 4, which extends from the side of the first connector 21 in a direction different from that of the trunk cable 3; a third connector 23, which is arranged at the front end of the branch cable 4 and can be detachably mounted on the wheel speed sensor 7; a rubber cover component 5; and first to third fastening components 61~63.

[0030] The first connector 21 is one form of the "one side connector" of the present invention, and the second connector 2 is one form of the "other side connector" of the present invention. The trunk cable 3 is one form of the "first cable" of the present invention, and the branch cable 4 is one form of the "second cable" of the present invention. The trunk cable 3 is longer than the branch cable 4, has more wires than the branch cable 4, and has a larger outer diameter than the branch cable 4.

[0031] The trunk cable 3 includes first to fourth signal lines 31 to 34 and a sheath 35 covering the first to fourth signal lines 31 to 34. The first signal line 31 and the second signal line 32, and the third signal line 33 and the fourth signal line 34 are twisted together to form a twisted pair. The first to fourth signal lines 31 to 34 are insulated wires formed by covering central conductors 311, 321, 331, 341 with insulators 312, 322, 332, 342. The central conductors 311, 321, 331, 341 are twisted wires formed by twisting a plurality of wires made of copper or copper alloy. The insulators 312, 322, 332, 342 are made of insulating resins such as polyethylene and fluororesin. The sheath 35 is made of a resin such as polyurethane. In the present embodiment, the sheath 35 is formed by full extrusion, and the outer peripheral surface 35a of the sheath 35 is circular. In the present embodiment, the trunk cable 3 includes the first to fourth signal lines 31 to 34 (signal lines only), but may include a plurality of power lines (for supplying power to the electric brake unit 16 ) and a plurality of signal lines in combination.

[0032] The branch cable 4 has a fifth and a sixth signal line 41, 42. The fifth and the sixth signal line 41, 42 are insulated wires formed by covering the center conductors 411, 421 with insulators 412, 422, and are twisted to form a twisted pair. The center conductors 411, 421 are twisted wires formed by twisting a plurality of wires made of copper or copper alloy. The insulators 412, 422 are made of insulating resin such as polyethylene or fluororesin. In addition, the fifth signal line 41 and the sixth signal line 42 may not be twisted. The fifth and the sixth signal lines 41, 42 transmit the detection signal of the wheel speed sensor 7.

[0033] The cover component 5 integrally comprises: a first cylindrical portion 51, which covers a portion of the trunk cable 3 (the sheath 35, and the first to fourth signal lines 31 to 34 exposed from the sheath 35); a second cylindrical portion 52, which covers at least a portion of the branch cable 4; and a connector cover portion 53, which covers a portion of the first connector 21. In the present embodiment, the cover component 5 is made of EPDM (ethylene propylene rubber). However, the material of the cover component 5 is not limited to EPDM, and a suitable material (butyl rubber, silicone rubber, fluororubber, etc.) can be used as long as it has elasticity and waterproofness as well as the required weather resistance and durability. The cover component 5 is formed by, for example, allowing a molten rubber material to flow into a mold and solidify, and the first cylindrical portion 51, the second cylindrical portion 52 and the connector cover portion 53 are made of the same rubber material.

[0034] The length of the second cylindrical portion 52 from the connector cover portion 53 is longer than the length of the first cylindrical portion 51 from the connector cover portion 53. This is because the length between the first connector 21 and the third connector 23 of the branch cable 4 is longer than the length of the portion of the first to fourth signal lines 31 to 34 exposed from the sheath 35. Thus, the first to fourth signal lines 31 to 34 and the branch cable 4 exposed from the sheath 35 can be protected from cracking, etc., and unnecessary extension of the length of the first cylindrical portion 51 can be suppressed. For example, the cover component 5 can be made lightweight. In addition, the second cylindrical portion 52 is formed to have an inner and outer diameter smaller than that of the first cylindrical portion 51. As Figure 5 As shown, in the natural state where no external force is applied to the cover member 5, the second cylindrical portion 52 is bent in such a manner that the front end portion of the second cylindrical portion 52 is directed toward the wheel speed sensor 7. By bending the second cylindrical portion 52, it is possible to prevent a part of the second cylindrical portion 52 from being bent when the wire harness 1 is assembled to the vehicle 100 so that the fifth and sixth signal lines 41 and 42 are pressed by the second cylindrical portion 52, or the second cylindrical portion 52 from being damaged due to wear or the like.

[0035] The third connector 23 has a cylindrical protrusion 231, and the second cylindrical portion 52 is fixed to the protrusion 231 (as a part of the third connector 23). A portion of the third connector 23 including the front end of the protrusion 231 is housed inside the second cylindrical portion 52. The rigidity of the material of the protrusion 231 is higher than the rigidity of the material of the second cylindrical portion 52. In the present embodiment, the second cylindrical portion 52 covers the entirety of the fifth and sixth signal lines 41, 42 between the first connector 21 and the third connector 23. However, if the second cylindrical portion 52 covers at least a portion of the fifth and sixth signal lines 41, 42 between the first connector 21 and the third connector 23, the fifth and sixth signal lines 41, 42 can be protected by the second cylindrical portion 52, thereby suppressing damage to the branch cable 4 caused by cracking, etc.

[0036] The front end portion of the first cylindrical portion 51 is fastened by the first fastening member 61. The first fastening member 61 fastens the front end portion of the first cylindrical portion 51 toward the sheath 35. The front end portion of the second cylindrical portion 52 is fastened by the second fastening member 62. The second fastening member 62 is arranged on the outer periphery of the protrusion 231 of the third connector 23, and fastens the front end portion of the second cylindrical portion 52 toward the protrusion 231 of the third connector 23. The connector cover 53 is fastened by the third fastening member 63 toward the connector housing 210 of the first connector 21. The first to third fastening members 61 to 63 suppress the entry of foreign matter such as moisture into the inner side of the cover member 5, and suppress the positional deviation of the first cylindrical portion 51, the second cylindrical portion 52 and the connector cover 53.

[0037] The first to third fastening members 61 to 63 include a strip-shaped portion 611, 621, 631 having a plurality of locking protrusions 611a, 621a, 631a formed along the length direction, and a head portion 612, 622, 632 provided at one end of the strip-shaped portion 611, 621, 631. The head portion 612, 622, 632 includes an insertion hole 612a, 622a, 632a into which the strip-shaped portion 611, 621, 631 is inserted, and a locking portion 612b, 622b, 632b that locks any one of the plurality of locking protrusions 611a, 621a, 631a inside the insertion hole 612a, 622a, 632a. The first to third fastening members 61 to 63 are made of, for example, nylon resin, but may also be made of metal such as stainless steel. In addition, as a method of fixing the cover member 5 to the trunk cable 3, the first connector 21 and the third connector 23, a tape provided in a manner such that an adhesive layer contacts the cover member 5, the trunk cable 3, the first connector 21 and the third connector 23 may be used.

[0038] When assembling the wire harness 1, the front ends of the strips 611, 621, 631 of the first to third fastening members 61 to 63 are inserted into the insertion holes 612a, 622a, 632a, and the strips 611, 621, 631 are pulled out from the insertion holes 612a, 622a, 632a until a suitable fastening force is generated. The locking portions 612b, 622b, 632b are locked to one of the locking protrusions 611a, 621a, 631a in the insertion holes 612a, 622a, 632a when the strips 611, 621, 631 are pulled out to the longest extent. Alternatively, the excess length of the strips 611, 621, 631 pulled out from the insertion holes 612a, 622a, 632a may be cut off using pliers or the like.

[0039] Figure 6 This is an explanatory diagram showing the wiring structure of the first connector 21 and its surroundings. The first connector 21 has a connector housing 210 made of resin and first to sixth terminals 211 to 216 held by the connector housing 210. The center conductors 311, 321, 331, 341, 411, 421 of the first to sixth signal lines 31 to 34, 41, 42 are crimped to the first to sixth terminals 211 to 216. The connector housing 210 is made of a material having higher rigidity than the material of the cover member 5. The connector housing 210 accommodates a portion of each of the first to sixth signal lines 31 to 34, 41, 42 and a portion of each of the first to sixth terminals 211 to 216.

[0040] The first connector 21 is engaged with a connector 81 mounted on a substrate 80 of the brake controller 8. The connector 81 has first to sixth connection terminals 811 to 816 to which the first to sixth terminals 211 to 216 of the first connector 21 are connected, respectively. The first and second connection terminals 811 and 812 are connected to a control circuit 82 of the brake controller 8 through wiring patterns 801 and 802 formed on the substrate 80. The control circuit 82 controls the electric motor, which is the driving source of the electric brake unit 16, based on a control signal sent from the main controller 9. The brake caliper 163 and the piston 164 of the electric brake unit 16 are actuated by the driving force of the electric motor.

[0041] The brake controller 8 and the main controller 9 communicate via the first and second signal lines 31 and 32 of the trunk cable 3. The first and second signal lines 31 and 32 transmit control signals between the brake controller 8 and the main controller 9. The control signal sent from the main controller 9 to the brake controller 8 includes information on the braking force of the wheel 11 to be generated by the electric brake unit 16. The control signal sent from the brake controller 8 to the main controller 9 includes information indicating the operating state of the electric brake unit 16, such as the rotation speed of the electric motor and the current supplied to the electric motor.

[0042] The third connection terminal 813 and the fifth connection terminal 815, and the fourth connection terminal 814 and the sixth connection terminal 816 of the connector 81 are electrically short-circuited. As a result, the central conductor 411 of the fifth signal line 41 of the branch cable 4 is electrically connected to the central conductor 331 of the third signal line 33 of the trunk cable 3, and the central conductor 421 of the sixth signal line 42 of the branch cable 4 is electrically connected to the central conductor 341 of the fourth signal line 34 of the trunk cable 3.

[0043] exist Figure 6 In the example shown, the third connection terminal 813 is electrically connected to the fifth connection terminal 815 by a short-circuit component 817, and the fourth connection terminal 814 is electrically connected to the sixth connection terminal 816 by a short-circuit component 818. The short-circuit components 817 and 818 are metal parts made of conductive metal. In addition, the third connection terminal 813 and the fifth connection terminal 815, and the fourth connection terminal 814 and the sixth connection terminal 816 can also be electrically short-circuited by, for example, a wiring pattern formed on the substrate 80.

[0044] The detection signal of the wheel speed sensor 7 transmitted through the fifth and sixth signal lines 41 and 42 is propagated to the third and fourth signal lines 33 and 34 of the trunk cable 3 via the short-circuit components 817 and 818, and is sent to the main controller 9 through the third and fourth signal lines 33 and 34 of the trunk cable 3. The main controller 9 sends a control signal to the brake controller 8 based on the rotation speed of the wheel 11 obtained according to the detection signal of the wheel speed sensor 7. The control of the braking force performed by the main controller 9 includes anti-lock control for suppressing the locking of the wheel 11. In addition, the brake controller 8 can also have a part of the control function of the braking force. In this case, the detection signal of the wheel speed sensor 7 is also input to the control circuit 82 of the brake controller 8.

[0045] (Effects of Embodiments)

[0046] According to the embodiment described above, the cover component 5 covers the branch cable 4 together with a part of the first connector 21, so that the positional deviation of the cover component 5 can be suppressed and the branch cable 4 can be appropriately protected. As a result, damage to the branch cable 4 due to cracking or the like can be suppressed. In addition, the cover component 5 also covers a part of the trunk cable 3, so that the positional deviation of the cover component 5 can be more reliably suppressed, and foreign matter can be suppressed from entering the inside of the cover component 5. In addition, damage to the trunk cable 3 (especially the first to fourth signal lines 31 to 34 exposed from the sheath 35) due to cracking or the like can be suppressed. In addition, in the present embodiment, the first cylindrical portion 51 of the cover component 5 and the front end portion of the second cylindrical portion 52 and the connector cover portion 53 are fastened by the first to third fastening components 61 to 63, so that the positional deviation can be further reliably suppressed and the intrusion of foreign matter can be prevented.

[0047] (Modification of Cover Member)

[0048] Figure 7 It is a three-dimensional diagram showing a modified example of the cover component 5. The cover component 5 is the same as the above-mentioned embodiment, and integrally has a first cylindrical portion 51, a second cylindrical portion 52, and a connector cover portion 53, but the second cylindrical portion 52 has a corrugated structure formed by alternating multiple recessed portions 521 and convex portions 522 of different outer diameters. The second cylindrical portion 52 has a corrugated structure, so that the second cylindrical portion 52 is easy to bend, which can prevent a part of the second cylindrical portion 52 from bending and compressing the first and second signal lines 41, 42, etc. when the wiring harness 1 is assembled in the vehicle 100. On the other hand, the first cylindrical portion 51, which is shorter than the second cylindrical portion 52, does not have a corrugated structure. As a result, the mold for forming the cover component 5 can be simplified.

[0049] exist Figure 7In the example shown, the second cylindrical portion 52, except for the front end portion, to which the second fastening member 62 is attached, is formed with a corrugated structure. However, the entire second cylindrical portion 52 may also be a corrugated structure. That is, at least a portion of the second cylindrical portion 52 may be a corrugated structure.

[0050] (Modification of Trunk Cable and Branch Cable)

[0051] Figure 8 2 is a structural diagram showing a modified example of the wiring structure of the trunk cable 3 and the branch cable 4. Figure 8 In, with Figure 2 Similarly, the cover member 5 is virtually indicated by a two-dot chain line, and the inside of the cover member 5 is indicated by a solid line. In the above embodiment, the fifth and sixth signal lines 41 and 42 of the branch cable 4 are electrically connected to the third and fourth signal lines 33 and 34 of the trunk cable 3. Figure 8 In the modified example shown, the third and fourth signal lines 33 and 34 of the trunk cable 3 led out from the sheath 35 inside the cover member 5 (bent between the end of the sheath 35 and the first connector 21) are introduced into the second cylindrical portion 52 without passing through the first connector 21 and the brake controller 8, and constitute the branch cable 4. That is, in the above-mentioned embodiment, the branch cable 4 is separated from the trunk cable 3, but in this modified example, the branch cable 4 is a part of the trunk cable 3. According to this structure, the same effect as the above-mentioned embodiment can be obtained.
