Description

[Technical field]

[0001] The present invention relates to a wire harness. [Background technology]

[0002] Conventionally, for example, a wire harness having a plurality of connectors and cables has been used to electrically connect a plurality of connection objects in a vehicle. The wire harness described in Patent Document 1 includes a first group of electric wires, one end of which is connected to a first connector and the other end of which is connected to a second connector, and a second group of electric wires, one end of which is connected to the first connector and which branches off from the first group of electric wires at the position of the second connector or the connecting partner that is the second connector, and the other end of which is connected to a third connector. An exterior material such as a corrugated tube or a spirally wound adhesive tape is provided between the second connector and the third connector so as to cover the second group of electric wires. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6761398 Summary of the Invention [Problem to be solved by the invention]

[0004] When the wire harness configured as described above is arranged between the vehicle body side and the wheel side of a vehicle, chipping is likely to occur due to flying stones kicked up by the tires. In the one described in Patent Document 1, the second group of electric wires is protected by an exterior material, but when a corrugated tube is used as the exterior material, if the position of the corrugated tube in the longitudinal direction of the second group of electric wires is not fixed, there is a risk that the area where chipping is likely to occur cannot be adequately protected. In addition, when an adhesive tape is used as the exterior material, there is a risk of problems such as the labor required for spirally winding the adhesive tape and peeling due to a decrease in adhesiveness over time.

[0005] Therefore, an object of the present invention is to provide a wire harness capable of suppressing damage due to chipping or the like. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the present invention provides a wire harness comprising first and second cables, a one-side connector provided at one end of the first cable, and a cover member that covers at least a portion of the second cable together with a portion of the one-side connector. Effect of the Invention

[0007] According to the wire harness of the present invention, damage due to chipping or the like can be suppressed. [Brief description of the drawings]

[0009] [Embodiment Mode] 1 is a schematic diagram showing a configuration example of a vehicle 100 equipped with a wire harness 1 according to an embodiment of the present invention. In the vehicle 100, a wheel 11 having a wheel 111 and a tire 112 is supported on a vehicle body 10 by a suspension device 12. The suspension device 12 is configured to include an upper arm 121, a lower arm 122, a damper 123, and a suspension spring 124. One end of each of the upper arm 121 and the lower arm 122 is connected to a knuckle 13, and the other end is connected to the vehicle body 10.

[0010] The knuckle 13 has a first connecting portion 131 to which the upper arm 121 and the damper 123 are connected, a second connecting portion 132 to which the lower arm 122 is connected, and a mounting portion 133 to which the electric brake unit 16 is attached. In addition, an outer ring 141 of a hub unit 14 that rotatably supports the wheel 11 is fixed to the knuckle 13.

[0011] The hub unit 14 has an outer ring 141 and a hub ring 142 supported rotatably relative to the outer ring 141. A plurality of rolling elements (not shown) are held by a cage and arranged between the inner peripheral surface of the outer ring 141 and the outer peripheral surface of the hub ring 142. A wheel mounting flange 142a is provided on the hub ring 142, and the wheel 111 is attached to this wheel mounting flange 142a together with the brake rotor 15 by a plurality of hub bolts 143. The brake rotor 15 integrally has a friction portion 151 that frictionally slides against brake pads 161, 162 of the electric brake unit 16, and a fixed portion 152 that is fixed to the wheel mounting flange 142a of the hub ring 142.

[0012] A wheel speed sensor 7 is attached to the outer ring 141 of the hub unit 14. The wheel speed sensor 7 detects the rotational speed of the hub wheel 142 relative to the outer ring 141 as the rotational speed of the wheel 11. Specifically, a magnetic field detection element such as a Hall IC detects changes in the magnetic field of a magnetic encoder attached to the hub wheel 142, and outputs a pulse signal with a pulse interval according to the rotational speed of the hub wheel 142 relative to the outer ring 141 as a detection signal.

[0013] The electric brake unit 16 has an outer brake pad 161 and an inner brake pad 162, a caliper 163 to which the outer brake pad 161 is attached, a piston 164 to which the inner brake pad 162 is attached, and a caliper bracket 165 fixed to the mounting portion 133 of the knuckle 13. The caliper 163 is supported by the caliper bracket 165 and is movable parallel to the rotation axis of the wheel 11.

[0014] The vehicle 100 includes a brake controller 8 that controls the electric brake unit 16, and an overall controller 9 that performs overall control of the vehicle 100. The brake controller 8 and the wheel speed sensor 7 are disposed on the wheel side, and move vertically together with the wheels 11 relative to the vehicle body 10 as the suspension springs 124 expand and contract. The overall controller 9 is disposed on the vehicle body side. The brake controller 8 is one aspect of the "wheel side control device" of the present invention, and the overall controller 9 is one aspect of the "vehicle body side control device" of the present invention.

[0015] The wire harness 1 connects the brake controller 8 to the wheel speed sensors 7 and the general controller 9. Next, the configuration of the wire harness 1 will be described in detail.

[0016] Fig. 2(a) is a partially enlarged view of Fig. 1. Fig. 2(b) is an explanatory diagram showing the cover member 5 of the wire harness 1 of the portion shown in Fig. 2(a) virtually with a two-dot chain line and the inside of the cover member 5 with a solid line. Fig. 3 is a configuration diagram of the wire harness 1. Fig. 4(a) is a cross-sectional view taken along line AA in Fig. 3. Fig. 4(b) is a cross-sectional view taken along line BB in Fig. 3. Fig. 4(c) is a cross-sectional view taken along line CC in Fig. 3. Fig. 5 is a perspective view showing the cover member 5 alone.

[0017] The wire harness 1 includes a first connector 21 detachably attached to the brake controller 8, a second connector 22 detachably attached to the overall controller 9, a main cable 3 between the first connector 21 and the second connector 22, a branch cable 4 extending from the first connector 21 in a direction different from the main cable 3, a third connector 23 provided at the end of the branch cable 4 and detachably attached to the wheel speed sensor 7, a rubber cover member 5, and first to third fastening members 61 to 63.

[0018] The first connector 21 is an embodiment of the "one-side connector" of the present invention, and the second connector 2 is an embodiment of the "other-side connector" of the present invention. The trunk cable 3 is an embodiment of the "first cable" of the present invention, and the branch cable 4 is an embodiment of the "second cable" of the present invention. The trunk cable 3 is longer than the branch cable 4, has more electric wires than the branch cable 4, and has a larger outer diameter than the branch cable 4.

[0019] The trunk cable 3 includes first to fourth signal wires 31 to 34 and a sheath 35 covering the first to fourth signal wires 31 to 34. The first signal wire 31 and the second signal wire 32, and the third signal wire 33 and the fourth signal wire 34 are twisted together to form a twisted pair wire. The first to fourth signal wires 31 to 34 are insulated wires in which central conductors 311, 321, 331, and 341 are covered with insulators 312, 322, 332, and 342. The central conductors 311, 321, 331, and 341 are twisted wires in which a plurality of strands made of copper or copper alloy are twisted together. The insulators 312, 322, 332, and 342 are made of insulating resin such as polyethylene or fluororesin. The sheath 35 is made of resin such as urethane. In this embodiment, the sheath 35 is formed by solid extrusion, and the outer circumferential surface 35a of the sheath 35 is circular. Note that, in this embodiment, the trunk cable 3 includes the first to fourth signal lines 31 to 34 (signal lines only), but may include a combination of a plurality of power lines (for supplying power to the electric brake unit 16) and a plurality of signal lines.

[0020] The branch cable 4 has fifth and sixth signal wires 41, 42. The fifth and sixth signal wires 41, 42 are insulated wires in which central conductors 411, 421 are covered with insulators 412, 422, and are twisted together to form a twisted pair wire. The central conductors 411, 421 are twisted wires in which a plurality of wires made of copper or a copper alloy are twisted together. The insulators 412, 422 are made of insulating resin such as polyethylene or fluororesin. The fifth signal wire 41 and the sixth signal wire 42 do not have to be twisted together. The fifth and sixth signal wires 41, 42 transmit detection signals of the wheel speed sensors 7.

[0021] The cover member 5 integrally includes a first cylindrical portion 51 that covers a part 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 that covers at least a part of the branch cable 4, and a connector cover portion 53 that covers a part of the first connector 21. In this embodiment, the cover member 5 is made of EPDM (ethylene propylene rubber). However, the material of the cover member 5 is not limited to EPDM, and any appropriate material (butyl rubber, silicone rubber, fluororubber, etc.) can be used as long as it has elasticity, waterproofness, and necessary weather resistance and durability. The cover member 5 is formed, for example, by pouring a molten rubber material into a mold and solidifying it, and the first cylindrical portion 51, the second cylindrical portion 52, and the connector cover portion 53 are made of the same rubber material.

[0022] 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. This makes it possible to protect the first to fourth signal lines 31 to 34 exposed from the sheath 35 and the branch cable 4 from chipping and the like, while suppressing the length of the first cylindrical portion 51 from being unnecessarily long, and for example, makes it possible to reduce the weight of the cover member 5. In addition, the second cylindrical portion 52 is formed to have a smaller inner and outer diameter than the first cylindrical portion 51. As shown in FIG. 5, in the cover member 5, in a natural state where no external force is applied, the second cylindrical portion 52 is curved so that the tip of the second cylindrical portion 52 faces the wheel speed sensor 7. Because the second tubular portion 52 is curved, when the wire harness 1 is assembled to the vehicle 100, it is possible to prevent a part of the second tubular portion 52 from bending, which would cause the fifth and sixth signal lines 41, 42 to be pressed by the second tubular portion 52, or to prevent the second tubular portion 52 from being torn due to wear or the like.

[0023] The third connector 23 has a cylindrical protruding portion 231, and the second cylindrical portion 52 is fixed to the protruding portion 231 (which is a part of the third connector 23). A part of the third connector 23, including the tip of the protruding portion 231, is accommodated inside the second cylindrical portion 52. The rigidity of the material of the protruding portion 231 is higher than the rigidity of the material of the second cylindrical portion 52. In this embodiment, the second cylindrical portion 52 covers the entire 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 part 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 are protected by the second cylindrical portion 52, and damage to the branch cable 4 due to chipping or the like can be suppressed.

[0024] The tip of the first tubular portion 51 is fastened by a first fastening member 61. The first fastening member 61 fastens the tip of the first tubular portion 51 toward the sheath 35. The tip of the second tubular portion 52 is fastened by a second fastening member 62. The second fastening member 62 is disposed on the outer periphery of the protruding portion 231 of the third connector 23 and fastens the tip of the second tubular portion 52 toward the protruding portion 231 of the third connector 23. The connector cover portion 53 is fastened by a third fastening member 63 toward the connector housing 210 of the first connector 21. The first to third fastening members 61 to 63 prevent foreign matter such as moisture from entering the inside of the cover member 5 and also prevent the first tubular portion 51, the second tubular portion 52, and the connector cover portion 53 from being misaligned.

[0025] The first to third fastening members 61 to 63 have band-shaped parts 611, 621, 631 on which a plurality of locking projections 611a, 621a, 631a are formed along the longitudinal direction, and head parts 612, 622, 632 provided at one end of the band-shaped parts 611, 621, 631. The head parts 612, 622, 632 have insertion holes 612a, 622a, 632a into which the band-shaped parts 611, 621, 631 are inserted, and locking parts 612b, 622b, 632b that lock any of the plurality of locking projections 611a, 621a, 631a inside the insertion holes 612a, 622a, 632a. The first to third fastening members 61 to 63 are made of, for example, nylon resin, but may be made of metal such as stainless steel. In addition, the means for fixing the cover member 5 to the trunk cable 3, the first connector 21, and the third connector 23 may be an adhesive tape arranged so that the adhesive layer is in contact with the cover member 5, the trunk cable 3, the first connector 21, and the third connector 23.

[0026] When assembling the wire harness 1, the ends of the band-shaped parts 611, 621, 631 of the first to third fastening members 61 to 63 are inserted into the insertion holes 612a, 622a, 632a, and the band-shaped parts 611, 621, 631 are pulled out from the insertion holes 612a, 622a, 632a until an appropriate fastening force is generated. The locking parts 612b, 622b, 632b lock one of the locking projections 611a, 621a, 631a located in the insertion holes 612a, 622a, 632a when the band-shaped parts 611, 621, 631 are pulled out to the maximum. The excess parts of the band-shaped parts 611, 621, 631 pulled out from the insertion holes 612a, 622a, 632a may be cut off with nippers or the like.

[0027] 6 is an explanatory diagram showing the first connector 21 and its surrounding wiring configuration. The first connector 21 has a resin connector housing 210 and first to sixth terminals 211 to 216 held by the connector housing 210. The central conductors 311, 321, 331, 341, 411, and 421 of the first to sixth signal lines 31 to 34, 41, and 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 part of each of the first to sixth signal lines 31 to 34, 41, and 42 and a part of each of the first to sixth terminals 211 to 216.

[0028] The first connector 21 is fitted into 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 respectively connected. Of these, the first and second connection terminals 811, 812 are connected to a control circuit 82 of the brake controller 8 by wiring patterns 801, 802 formed on the substrate 80. The control circuit 82 controls the electric motor, which is the drive source of the electric brake unit 16, based on a control signal sent from the overall controller 9. A caliper 163 and a piston 164 of the electric brake unit 16 are operated by the drive force of the electric motor.

[0029] The brake controller 8 and the overall controller 9 communicate with each other via the first and second signal lines 31, 32 of the trunk cable 3. The first and second signal lines 31, 32 transmit control signals between the brake controller 8 and the overall controller 9. The control signal sent from the overall controller 9 to the brake controller 8 includes information on the braking force of the wheels 11 to be generated by the electric brake unit 16. The control signal sent from the brake controller 8 to the overall 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.

[0030] 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, respectively. 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.

[0031] 6, the third connection terminal 813 and the fifth connection terminal 815 are electrically connected by a short-circuit member 817, and the fourth connection terminal 814 and the sixth connection terminal 816 are electrically connected by a short-circuit member 818. The short-circuit members 817 and 818 are metal fittings made of conductive metal. Note that the third connection terminal 813 and the fifth connection terminal 815, and the fourth connection terminal 814 and the sixth connection terminal 816 may be electrically short-circuited by, for example, a wiring pattern formed on the substrate 80.

[0032] The detection signal of the wheel speed sensor 7 transmitted through the fifth and sixth signal lines 41, 42 is propagated to the third and fourth signal lines 33, 34 of the trunk cable 3 via the short-circuiting members 817, 818, and is sent to the general controller 9 through the third and fourth signal lines 33, 34 of the trunk cable 3. The general controller 9 sends a control signal to the brake controller 8 based on the rotational speed of the wheels 11 obtained from the detection signal of the wheel speed sensor 7. The braking force control performed by the general controller 9 includes anti-lock control for suppressing locking of the wheels 11. Note that part of the braking force control function may be provided to the brake controller 8. In this case, the detection signal of the wheel speed sensor 7 is also input to a control circuit 82 of the brake controller 8.

[0033] (Effects of the embodiment) According to the embodiment described above, since the cover member 5 covers the branch cable 4 together with a part of the first connector 21, it is possible to prevent the cover member 5 from being displaced and to appropriately protect the branch cable 4. This makes it possible to prevent damage to the branch cable 4 due to chipping or the like. Furthermore, since the cover member 5 also covers a part of the trunk cable 3, it is possible to more reliably prevent the cover member 5 from being displaced and to prevent foreign matter from entering the inside of the cover member 5. It is also possible to prevent damage to the trunk cable 3 (particularly the first to fourth signal lines 31 to 34 exposed from the sheath 35) due to chipping or the like. Furthermore, in this embodiment, since the tip portions of the first cylindrical portion 51 and the second cylindrical portion 52 of the cover member 5 and the connector cover portion 53 are fastened by the first to third fastening members 61 to 63, it is possible to more reliably prevent the cover member 5 from being displaced and to prevent the intrusion of foreign matter.

[0034] (Modification of Cover Member) FIG. 7 is a perspective view showing a modified example of the cover member 5. As in the above embodiment, the cover member 5 has a first cylindrical portion 51, a second cylindrical portion 52, and a connector cover portion 53 integrally formed therewith, but the second cylindrical portion 52 has a bellows structure in which a plurality of recesses 521 and protrusions 522 having different outer diameters are alternately formed. Since the second cylindrical portion 52 has a bellows structure, the second cylindrical portion 52 is easily bent, and when the wire harness 1 is assembled to the vehicle 100, it is possible to prevent a part of the second cylindrical portion 52 from being bent and compressing the first and second signal lines 41, 42. On the other hand, the first cylindrical portion 51, which is shorter in length than the second cylindrical portion 52, does not have a bellows structure. This makes it possible to simplify the mold for forming the cover member 5.

[0035] 7, a bellows structure is formed in a portion of the second tubular portion 52 excluding the tip portion to which the second fastening member 62 is attached. However, the entire second tubular portion 52 may have the bellows structure. In other words, it is sufficient that at least a portion of the second tubular portion 52 has the bellows structure.

[0036] (Modifications of trunk and branch cables) FIG. 8 is a configuration diagram showing a modified example of the wiring structure of the trunk cable 3 and the branch cable 4. In FIG. 8, as in FIG. 2, the cover member 5 is virtually shown by a two-dot chain line, and the inside of the cover member 5 is shown by a solid line. In the above embodiment, the fifth and sixth signal lines 41, 42 of the branch cable 4 are electrically connected to the third and fourth signal lines 33, 34 of the trunk cable 3. In the modified example shown in FIG. 8, the third and fourth signal lines 33, 34 of the trunk cable 3 led out from the sheath 35 inside the cover member 5 are bent (between the end of the sheath 35 and the first connector 21) and introduced into the second tubular portion 52 without passing through the first connector 21 or the brake controller 8, thereby forming the branch cable 4. That is, in the above embodiment, the branch cable 4 is separate from the trunk cable 3, but in this modified example, the branch cable 4 is a part of the trunk cable 3. With this configuration, the same effect as in the above embodiment can be obtained.

[0037] (Summary of the embodiment) Next, the technical ideas grasped from the above-described embodiment and modified examples will be described by using the reference numerals and the like in the embodiment and modified examples. However, the reference numerals and the like in the following description do not limit the components in the claims to the members and the like specifically shown in the embodiment and modified examples.

It should be noted that not all of the combinations of features described in the embodiment are necessarily essential to the means for solving the problems of the invention.

[0046] Furthermore, the present invention can be modified appropriately without departing from the spirit of the present invention.

The branch cable 4 may be directly connected to the wheel speed sensor 7 without the third connector 23. In this case, the central conductors 411 and 421 of the fifth and sixth signal lines 41 and 42 are electrically connected to the terminals of the detection element in the case of the wheel speed sensor 7. Furthermore, instead of providing the third connector 23, a resin molding (molded resin molding) that collectively covers the magnetic detection element for the wheel speed sensor 7 and the end of the branch cable 4 may be provided at the end of the branch cable 4.
