Summary of the Invention

Problems to be Solved by the Invention

[0004] Some vehicle wire harnesses have a portion of their length suspended in the air, allowing them to swing. For example, in a wire harness connecting a vehicle's electric brake and control device, one end of the harness is fixed under the vehicle's spring, while a portion of the harness is suspended in the air. In such wire harnesses, it is desirable to secure the wires with high fixing strength at both ends of the portion suspended in the air to prevent misalignment of the wires relative to the vehicle body. However, if the wires are tightened too much from the outside of the corrugated tube, the corrugated tube will collapse. Also, if the wires are directly and strongly tightened after they exit the corrugated tube, the wires may be damaged.

[Figure 10] This is an explanatory diagram showing the manufacturing process of a wire harness according to the third embodiment. [Modes for carrying out the invention]

[0010] [Embodiment] (Configuration of the vehicle) FIG. 1(a) is an external view showing a vehicle 1 to which a wire harness 2 according to an embodiment of the present invention is attached. FIG. 1(b) is a configuration diagram showing one of a plurality of wheels 10 of the vehicle 1 and its peripheral part.

[0011] The wheel 10 is supported by a suspension device 12 so as to be movable in the vertical direction with respect to the vehicle body 11. The suspension device 12 includes 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 the knuckle 13, and the other end is connected to the vehicle body 11. The upper arm 121 is connected to the upper attachment portion 131 of the knuckle 13 together with the shock absorber 123, and the lower arm 122 is connected to the lower attachment portion 132 of the knuckle 13. The suspension spring 124 is coaxially arranged on the outer periphery of the shock absorber 123 and expands and contracts according to the vertical movement of the vehicle body 11 with respect to the road surface.

[0012] A hub unit 14, an electric brake device 15, and a rotational speed sensor 16 are attached to the knuckle 13. Hereinafter, the side closer to the wheel 10 than the suspension spring 124 is referred to as "under the spring", and the side closer to the vehicle body 11 is referred to as "above the spring". Under the spring, the wheel 10, the suspension device 12, the knuckle 13, the hub unit 14, and the electric brake device 15 are included. Above the spring, the vehicle body 11 and a tire house 111 fixed to the vehicle body 11 so as to surround the wheel 10 are included.

[0013] The hub unit 14 has an outer ring 141 fixed to the knuckle 13 by a plurality of bolts 140, and a hub ring 142 rotatably supported with respect to the outer ring 141. A wheel mounting flange 142a is provided on the hub ring 142, and the wheel 10 and the brake rotor 17 are attached to the wheel mounting flange 142a by a plurality of hub bolts 143. The electric brake device 15 presses a brake pad 151 against the brake rotor 17 to generate a frictional force and brakes the wheel 10. The rotational speed sensor 16 is fixed to the outer ring 141 and detects the magnetic field of a magnetic encoder that rotates integrally with the hub ring 142.

[0014] The vehicle 1 is equipped with a control device 100 that controls the electric brake device 15, and the control device 100 is electrically connected to the electric brake device 15 and the rotational speed sensor 16 by a wire harness 2. The wire harness 2 includes a cable portion 20 having a pair of power lines 31, 32, a signal line 4, and first to third corrugated tubes 51 to 53, and a plurality of brackets 6 for attaching the cable portion 20 to the vehicle 1.

[0015] The power lines 31, 32 are connected to the electric brake device 15 and supply power for operating the electric brake device 15 from the control device 100 to the electric brake device 15. The signal line 4 is connected to the rotational speed sensor 16 and sends a signal indicating the rotational speed of the wheel 10 from the rotational speed sensor 16 to the control device 100. The power lines 31, 32 and the signal line 4 are one aspect of the electric wire of the present invention.

[0016] The power lines 31, 32 and the signal line 4 are inserted into the first to third corrugated tubes 51 to 53. The first to third corrugated tubes 51 to 53 protect the power lines 31, 32 and the signal line 4 from flying objects such as stones and water droplets. The first to third corrugated tubes 51 to 53 are made of a synthetic resin such as polyamide, polypropylene, or polybutylene terephthalate and have flexibility.

[0017] At least one of the multiple brackets 6 is mounted above the spring. At least one of the other brackets 6 is mounted below the spring. Figure 1(b) shows two brackets 6, one of which is fixed to the upper mounting portion 131 of the knuckle 13 by a bolt 18, and the other bracket 6 is fixed to the wheel well 111 by a bolt 18.

[0018] The cable section 20 is suspended in the air between one bracket 6 and the other bracket 6. In other words, brackets 6 are provided at both ends of the portion 21 of the wire harness 2 that is suspended in the air. The first corrugated tube 51 is positioned between these two brackets 6. One bracket 6 on the knuckle 13 side is positioned between the first corrugated tube 51 and the second corrugated tube 52. The other bracket 6 on the wheel well 111 side is positioned between the first corrugated tube 51 and the third corrugated tube 53.

[0019] (Wire harness configuration) Figure 2 is a perspective view illustrating the configuration of wire harness 2. Figures 3(a) and 3(b) are external views showing a part of wire harness 2. Figure 4(a) is a cross-sectional view taken along line AA of Figure 3(b). Figure 4(b) is a cross-sectional view taken along line BB of Figure 3(b).

[0020] The power lines 31 and 32 are insulated wires having core wires 311 and 321 made by twisting together multiple conductor strands 310 and 320, and insulating coatings 312 and 322 covering the core wires 311 and 321. The signal line 4 has a pair of differential signal lines 41 and 42, and an internal sheath 43 that covers the pair of differential signal lines 41 and 42 together. The differential signal lines 41 and 42 are insulated wires formed to be smaller in diameter than the power lines 31 and 32, and have core wires 411 and 421 made by twisting together multiple conductor strands 410 and 420, and insulating coatings 412 and 422 covering the core wires 411 and 421. The internal sheath 43 is a solid structure formed by solid extrusion of a thermoplastic resin such as urethane.

[0021] The conductor strands 310, 320, 410, and 420 are made of a highly conductive metal such as a copper alloy or an aluminum alloy. The insulating coatings 312, 322, 412, and 422 are made of a thermoplastic resin, more specifically, polyamide, polypropylene, polyethylene, polyethylene terephthalate, etc.

[0022] The first to third corrugated tubes 51 to 53 have a bellows structure in which annular recesses 501 and annular protrusions 502 are alternately provided along the longitudinal direction, and the inner and outer diameters of the recesses 501 are formed to be smaller than the inner and outer diameters of the protrusions 502. In this embodiment, the case in which the first to third corrugated tubes 51 to 53 are tubular in shape without slits will be described. However, slits for accommodating power lines 31, 32 and signal lines 4 may be formed in the first to third corrugated tubes 51 to 53.

[0023] The wire harness 2 includes a plurality of gripping members arranged to cover parts of the power lines 31, 32 and signal lines 4 that are not covered by the first to third corrugated tubes 51 to 53. In this embodiment, these gripping members are grommets 7. The grommets 7 are arranged between the first corrugated tube 51 and the second corrugated tube 52, and between the first corrugated tube 51 and the third corrugated tube 53.

[0024] Furthermore, the wire harness 2 has an adhesive tape 8 as a closing member that closes the gap 200 (see Figure 3(a)) between the multiple grommets 7 and the first to third corrugated tubes 51 to 53. The adhesive tape 8 has an adhesive layer on one side of a strip-shaped base material made of synthetic resin, and is wound between the grommets 7 and the first to third corrugated tubes 51 to 53 with the adhesive layer facing inward. In addition to the adhesive tape 8, other closing members such as rubber rings or adhesives may also be used.

[0025] Figure 3(a) shows the state before the adhesive tape 8 is wrapped around it. Figure 3(b) shows the state after the adhesive tape 8 has been wrapped around the grommet 7 and the first to third corrugated tubes 51-53. The adhesive tape 8 is placed between one of the two grommets 7 shown in Figure 3(a) and the first and second corrugated tubes 51 and 52, and between the other grommet 7 and the first and third corrugated tubes 51 and 53. The adhesive tape 8 prevents foreign matter such as moisture from entering the inside of the first to third corrugated tubes 51-53 through the gap 200, and also fixes the first to third corrugated tubes 51-53 to the grommet 7, preventing the gap 200 from widening.

[0026] Figure 5 is a perspective view showing the grommet 7. The grommet 7 is, for example, an injection-molded body and is made of a material softer than the hardness of the materials of the first to third corrugated tubes 51 to 53. Specifically, as the material for the grommet 7, rubber materials such as ethylene propylene diene rubber (EPDM) or thermoplastic resins such as urethane can be used.

[0027] The grommet 7 has a first through-hole 71 and a second through-hole 72 through which power lines 31 and 32 are inserted, and a third through-hole 73 through which signal line 4 is inserted. The grommet 7 is cylindrical overall, and the first to third through-holes 71 to 73 are formed parallel to each other along its central axis. The adhesive tape 8 adheres to the outer surface 7a of the grommet 7 and the outer surface 502a of the protrusions 502 of the first to third corrugated tubes 51 to 53.

[0028] The bracket 6 has a mounting portion 61 that is attached to the mounting object and a gripping portion 62 that tightens and grips the grommet 7. In this embodiment, the bracket 6 is made of a single metal plate, and the mounting portion 61 and the gripping portion 62 are integrally formed. The mounting portion 61 is a flat plate with a mounting hole 610 formed through it in the thickness direction. The gripping portion 62 has an inner circumferential surface 62a that contacts the outer circumferential surface 7a of the grommet 7 and is curved to surround the outer circumference of the grommet 7. In the example shown in Figure 1(b), the mounting object of one bracket 6 is the knuckle 13, and the mounting object of the other bracket 6 is the wheel well 111. The mounting portion 61 is attached to these mounting objects by bolts 18 (see Figure 1(b)) inserted through the mounting hole 610.

[0029] Although the inner diameters of the first to third through holes 71 to 73 of the grommet 7 are larger than the outer diameters of the power lines 31 and 32 and the signal line 4 respectively, the gripping portion 62 of the bracket 6 tightens the grommet 7, causing the inner circumferential surfaces of the first to third through holes 71 to 73 to be in close contact with the outer circumferential surfaces of the power lines 31 and 32 and the signal line 4, thereby preventing foreign matter such as moisture from moving through the first to third through holes 71 to 73.

[0030] The gripping portion 62 of the bracket 6 grips the grommet 7 only in contact with the outer circumferential surface 7a of the grommet 7 where the adhesive tape 8 is not wrapped. In other words, the gripping portion 62 of the bracket 6 grips the grommet 7 in a way that does not pinch the adhesive tape 8 between it and the grommet 7. As a result, the inner surface 62a of the gripping portion 62 is in close contact with the outer circumferential surface 7a of the grommet 7, and the gripping portion 62 can reliably grip the grommet 7.

[0031] Furthermore, it is preferable to wrap the adhesive tape 8 around the grommet 7 while the gripping portion 62 of the bracket 6 is gripping it. By wrapping the adhesive tape 8 around the outer surface 7a of the grommet 7 while the grommet 7 is elastically deformed by the tightening of the gripping portion 62, the adhesion between the adhesive tape 8 and the grommet 7 is enhanced.

[0032] (Effects of the first embodiment) According to the first embodiment described above, the grommet 7 is positioned to cover a portion of the longitudinal direction of the power lines 31, 32 and signal lines 4 in the parts not covered by the first to third corrugated tubes 51 to 53, and the gripping portion 62 of the bracket 6 grips the grommet 7. This increases the fixing strength of the power lines 31, 32 and signal lines 4 by the bracket 6 while preventing damage to the power lines 31, 32 and signal lines 4.

[0033] (A variation of the grommet) Figure 6(a) is a perspective view showing a modified grommet 7A. Figure 6(b) is a cross-sectional view showing the grommet 7A being gripped by the gripping portion 62 of the bracket 6. In this modified example, a through hole 70 is formed in the grommet 7A, and power lines 31, 32 and signal line 4 are inserted through this through hole 70. The through hole 70 has a first insertion portion 701 through which the power line 31 is inserted, a second insertion portion 702 through which the power line 32 is inserted, and a third insertion portion 703 through which the signal line 4 is inserted, and the first to third insertion portions 701 to 703 are in communication with each other.

[0034] Even when using the grommet 7A according to this modified example, the same effects as in the first embodiment described above can be obtained. In addition, a slit (cut) may be formed from the outer surface 7a of the grommet 7A to the through hole 70 in order to facilitate the insertion of power lines 31, 32 and signal line 4 into the through hole 70.

[0035] [Second Embodiment] A second embodiment of the present invention will be described with reference to Figures 7(a) and 7(b). Figures 7(a) and 7(b) are external views showing a wire harness 2A according to the second embodiment.

[0036] In the first embodiment, a case in which no slits are formed in the first to third corrugated tubes 51 to 53 was described. In the second embodiment, a slit 511 is formed in the first corrugated tube 51 along its longitudinal direction. The slit 511 is a cut that allows power lines 31, 32 and signal lines 4 to be introduced into the first corrugated tube 51. When assembling the wire harness 2A, the slit 511 is widened to position the power lines 31, 32 and signal lines 4 inside the first corrugated tube 51.

[0037] The wire harness 2A has first to third adhesive tapes 81 to 83. The first adhesive tape 81 is wrapped longitudinally around the two brackets 6 and the first corrugated tube 51 shown in Figures 7(a) and (b). The second adhesive tape 82 is wrapped between the second corrugated tube 52 and one of the brackets 6, and the third adhesive tape 83 is wrapped between the third corrugated tube 53 and the other bracket 6.

[0038] The width W of the first adhesive tape 81 along the longitudinal direction of the first corrugated tube 51 is longer than the length L of the first corrugated tube 51, and both ends of the first adhesive tape 81 in the width direction are wrapped around the outer surfaces 7a at each end of the two grommets 7. The first corrugated tube 51 is closed by the first adhesive tape 81 so that the slit 511 does not open.

[0039] Furthermore, the second corrugated tube 52 and the third corrugated tube 53 may also be provided with slits, similar to the first corrugated tube 51, and these slits may be closed with adhesive tape.

[0040] According to this second embodiment, in addition to the effects of the first embodiment, it is easier to arrange the power lines 31, 32 and signal lines 4 inside the first corrugated tube 51, and the slit 511 is closed by the first adhesive tape 81, preventing the power lines 31, 32 and signal lines 4 from protruding from the first corrugated tube 51, and preventing foreign matter from entering the inside of the first corrugated tube 51 through the slit 511. Furthermore, since the entire slit 511 is closed by a single wide first adhesive tape 81, the wrapping work can be performed more easily compared to, for example, wrapping a thin strip of adhesive tape spirally around the first corrugated tube 51.

[0041] [Third Embodiment] A third embodiment of the present invention will be described with reference to Figures 8 to 10. Figure 8 is a perspective view illustrating the configuration of the wire harness 2B according to the third embodiment. Figures 9(a) and 9(b) are external views of the wire harness 2B. Figure 10 is an explanatory diagram showing the manufacturing process of the wire harness 2B.

[0042] In the first embodiment, the case in which the member to be gripped by the bracket 6 is a grommet 7 was described, but in the third embodiment, this member to be gripped is a molded resin member 9. The molded resin member 9 is arranged to cover a portion of the power lines 31, 32 that are not covered by the first to third corrugated tubes 51 to 53. The molded resin member 9 is made of a thermoplastic resin such as urethane and is integrated with the power lines 31, 32.

[0043] The molded resin member 9 is positioned between the first corrugated tube 51 and the second corrugated tube 52, and between the first corrugated tube 51 and the third corrugated tube 53. The gripping portion 62 of the bracket 6 grips the molded resin member 9. Adhesive tape 8 is wrapped around the outer circumferential surface 9a of the molded resin member 9 that is not gripped by the gripping portion 62.

[0044] Figure 9(a) shows the state before the adhesive tape 8 is wrapped around it. Figure 9(b) shows the state after the adhesive tape 8 has been wrapped around the outer circumference of the molded resin member 9 and the first to third corrugated tubes 51 to 53. The adhesive tape 8 is placed between one of the two molded resin members 9 shown in Figure 9(a) and the first and second corrugated tubes 51 and 52, and between the other molded resin member 9 and the first and third corrugated tubes 51 and 53.

[0045] Figure 10 shows a mold 90 for forming a molded resin member 9. The mold 90 has an upper mold 901 and a lower mold 902, with power lines 31 and 32 sandwiched between the upper mold 901 and the lower mold 902. In Figure 10, the upper mold 901 is shown by a dashed line (two-dot line). The molded resin member 9 is formed by injecting molten resin material into a cavity 900 formed between the upper mold 901 and the lower mold 902.

[0046] This third embodiment also provides the same effects as the first embodiment. Furthermore, compared to the first embodiment, the work of inserting the power lines 31 and 32 through the grommet 7 is eliminated, making it easier to assemble the wire harness 2B. The wire harnesses 2A and 2B according to the second and third embodiments can also be routed across the sprung mass and unsprung mass of the vehicle 1, similar to the wire harness 2 according to the first embodiment.

[0047] (Summary of the embodiments) Next, the technical concept understood from the first to third embodiments described above will be described using the reference numerals and other symbols from each embodiment.
