The present invention relates to a flexible harness exterior member configured to prevent interference and the like by restricting a bending direction and a bending radius between a vehicle body and a slide door of a wire harness that constantly supplies power to a slide door of an automobile, and the like. The present invention relates to a harness routing structure using a harness.
[0002]
[Prior art]
FIG. 7 shows a configuration in which a wire harness 42 is routed from the vehicle body (not shown) side to the slide door side so as to constantly supply power to electrical components and auxiliary equipment of the slide door 41 of the automobile, and a synthetic resin is provided on the slide door side. This shows a structure in which a wire harness 42 is bent and accommodated in a protector 43 made of a product and absorbs an excess length (slack) of the wire harness 42 due to opening and closing of the slide door 41 (for example, see Patent Document 1).
[0003]
The protector 43 is disposed between the door panel 49 and the door trim 50. The wire harness 42 is led out from the slit-shaped lower opening 44 of the protector 43 and is directed toward the vehicle body, and is routed from the front opening 45 of the protector 43 to an auxiliary machine or the like on the slide door side. A wire harness indicated by a chain line corresponds to a fully closed state of the slide door 41 in FIG. 8 (plan view), and a wire harness 42 indicated by a solid line corresponds to a fully opened state of the slide door 41 in FIG. 9 (plan view).
[0004]

[0007]
[Problems to be solved by the invention]
However, in the above harness wiring structure of the conventional slide door 41, there is no problem when the slide door 41 in FIG. 8 is fully closed, but when the slide door 41 in FIG. Since the reference numeral 42 easily interferes with the center pillar 52 of the vehicle body 47 and the like as shown by a chain line between the slide door 41 and the vehicle body 47 (crossover portion 51), it is necessary to pay attention to the arrangement position of the protector and the like. As mentioned above, it took time to design. Also, in the event that the wire harness 42 interferes with the wire harness 42, there is a concern that the reliability of the power supply is reduced due to the wear or deformation of the wire harness 42, and that the housing capacity (excess length absorption) is deteriorated. Was.
[0008]
In addition to the power supply to the slide door, for example, when wiring a wire harness while laying it on a vehicle body or the like, by bending the wire harness with a small radius in one direction and bending with a large radius in the other direction. In some cases, it is necessary to prevent interference with other structures and the like. In such a case, since the worker performs wiring while considering the bending radius of the wire harness one by one, the wiring work is troublesome, and If the wiring is performed by forgetting to change the bending radius, there is a concern that the wire harness may interfere with other structures or the like and cause wear or damage.
[0009]
Also, when a relatively rigid harness exterior member such as a synthetic resin corrugated tube is attached to the outer periphery of the wire harness, the bending radius is limited, and it is difficult to flexibly bend with a small radius. .
[0010]
In view of the above, the present invention can prevent interference between a wire harness and a vehicle body when opening and closing a slide door or the like, or easily route a wire harness to a vehicle body or the like with a desired bending radius.

[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
1 to 3 show an embodiment of a harness exterior member according to the present invention. 1 is a plan view, FIG. 2 is a side view, and FIG. 3 is a sectional view taken along line AA of FIG.
[0021]
The harness exterior member 60 is integrally formed using a synthetic rubber such as EPDM as a material, and has a bellows-like convex strip 61 and a concave groove 62 of a normal size on one side and the other side in the first half in the longitudinal direction. It has a bellows-like convex ridge 61 and a concave groove 62 of a normal size on one side of the latter half, and has a wide convex ridge 63 and a narrow concave groove 64 on the other side of the latter half. Things. The bellows portion 56 is constituted by the ridges 61 and 63 and the concave grooves 62 and 64.
[0022]
The ridges 61 and the grooves 62 having the normal size are, for example, ridges and grooves having substantially the same size and shape as the ridges and grooves of the bellows portion of the waterproof grommet usually used for the bent portion of the wire harness for a vehicle. It means a groove, and in the claims, it is expressed as a ridge having a small outer width and a concave groove having a large inner width.
[0023]
The outer surface of the wide ridge 63 is formed in a rectangular cross-section, and the opposing surfaces 63a on the outer surface side of each adjacent ridge 63 are located close to each other. A large bending radius is obtained by contact. The outer surface of the ridge 63 is formed in a rectangular cross section by a front and rear facing surface 63a which is vertical and a horizontal peripheral surface 63c which is orthogonal to the front and rear facing surface 63a. The outer surface of the ridge 61 having a normal size is formed in a substantially arc-shaped cross section, and the inner surfaces 61a and 63b (FIG. 15) of the ridges 61 and 63 and the valleys 62a and 64a of the concave grooves 62 and 64 are respectively formed in a cross section. It is formed in a substantially arc shape. The wide ridges 63 and the concave grooves 64 are formed thicker than the normal ridges 61 and the concave grooves 62 and have rigidity. The depth of the narrow groove 64 is slightly shallower than that of the normal groove 62. The size and shape of the inner surface 63b of the wide ridge 63 and the inner surface 61a of the ridge 61 of the normal size are the same. Thereby, the shape of the inner molding die (not shown) is constant and simplified.
[0024]
As shown in FIG. 1, a ridge 61 of a normal size continues on a radially opposite side of the wide ridge 63 via a step 69 perpendicular to the radial direction, and a diameter of a narrow groove 64 between the wide ridges 63. On the opposite side of the direction, a concave groove 62 of a normal size continues. Inner width P of narrow groove 64 ₁ Is the inner width P of the groove 62 having a normal size. ₂ About half of The switching position of the large and small ridges 61 and 63 and the concave portions 62 and 64 is on a plane (55) passing through the center line of the harness exterior member 60. The pitch and peak height (the outer diameter of the harness exterior member 60) of each of the ridges 61 and 63 are constant over the entire length of the bellows portion 56. The wide ridge 63 ′ is integrated with the narrow ridge 61 at the middle portion in the longitudinal direction of the bellows portion 56 (the boundary between the first half and the second half), and a rectangular outer surface portion 63 d is formed on one side in the width direction and an arc is formed on the other side. Has an outer surface portion 61b.
[0025]
The harness exterior member 60 can be easily formed, for example, by improving a mold (particularly, an outer molding mold) for forming a bellows portion of a waterproof grommet (not shown) for a vehicle. Since the material is rubber, there is no need to divide the product as in the case of molding a similar harness exterior member with a synthetic resin material. Absent).
[0026]
Cylindrical portions 66 and 67 having a diameter smaller than the outer diameter of the bellows portion 56 and substantially equal to the inner diameter of the bellows portion 56 are formed at both ends in the longitudinal direction of the harness exterior member 60. A long cylindrical portion 66 on the rear end side following 63 is fixed to the outer periphery of the wire harness 5 with a vinyl tape around in the harness fixing portion 68 (FIG. 4) on the vehicle body side, or is turned into the harness fixing portion 67. It is fixed to a rotating member (not shown) movably held. The concave grooves 62, 64 at the ends may be engaged with projections (not shown) in the harness fixing portion 68.
[0027]
However, since the harness exterior member 60 is made of rubber and has elasticity, when the slide door 2 (FIG. 4) is opened and closed, the harness exterior member 60 is rotated by a rotating member like a synthetic resin harness exterior member (not shown). There is very little need to absorb torsion. In a normal use mode, a torsion absorbing mechanism such as a rotating member is not required unless a very large twist acts. The short cylindrical portion 67 on the front end side is fixed to the outer periphery of the wire harness 5 by tape winding or the like, for example. Alternatively, the cylindrical portion 67 may be formed to have a small diameter, and may be brought into close contact with the wire harness 5 by a tension force.
[0028]
4 and 5 show an embodiment of a harness wiring structure in which the harness exterior member 60 is applied to a wire harness for supplying power to a sliding door of an automobile.
[0029]
The wire harness 5 is inserted into the exterior member 60 for the harness in advance, and one of the wire harnesses 5 is connected to each auxiliary device or the like in the slide door through the extra length absorbing device 24 on the slide door side, and the other of the wire harness 5 is connected to the other. A connector is connected to a wire harness (not shown) on the vehicle body side (battery side) via a harness fixing portion (fixing member) 68 on the vehicle body side. One end of the harness exterior member 60 is fixed to the wire harness 5, and the other end is fixed or held by the harness fixing portion 68.
[0030]
As shown in FIG. 4, when the slide door 2 is fully closed, each ridge 61 of a normal size on one side surface of the harness exterior member 60 is located inside the bending direction, and the rear half of the harness exterior member 60 is a harness fixing portion. With the fulcrum 68 as a fulcrum, it is smoothly bent toward the front of the vehicle with a small radius from the vehicle body side (in the sliding door closing direction). The front half of the harness exterior part 60 is located substantially straight toward the harness excess length absorbing device. Accordingly, interference between the inner surface of the door trim 2a made of synthetic resin of the slide door 2 and the harness exterior member 60 is prevented.
[0031]
The wire harness 5 and the harness exterior member 60 are led out to the outside along the inner surface of the door trim 2a. The wire harness 5 is configured such that a plurality of electric wires are bound by tape winding or covered with a thin flexible tube.
[0032]
When the slide door 2 of FIG. 4 is fully closed, each ridge 61 of a normal size inside the bend is bent at a large angle by a gap of a normal size, that is, a wide groove 62 as shown in FIG. In this state, the harness exterior member 60 bends in one direction with a small bending radius. At this time, since the wide ridges 63 on the outer side of the bend have the same pitch as the ridges 61 on the inner side of the bend, they are greatly opened from the narrow groove portions 64 to smoothly bend. This is promoted by the fact that the shape on the inner surface side of the wide ridge 63 (the shape of the inner surface 63b and the valley 64a in FIG. 3) is formed to be the same as the shape on the inner surface side of the normal ridge 61. .
[0033]
When the slide door 2 of FIG. 5 is fully opened, the other side surface of the harness exterior member 60 having the wide ridge 63 and the narrow groove 64 (FIG. 1) in the rear half portion is located inside the bend, and The abutment between the ridges 63 causes the harness fixing portion 68 to serve as a fulcrum to bend with a large radius from the vehicle body side, thereby preventing interference between the harness exterior member 60 and the center pillar 8 of the vehicle body 3.
[0034]
At the same time, the harness exterior member 60 is formed by a normal-sized ridge 61 and a concave groove 62 (FIG. 1) on the side farther away from the harness fixing portion 68 in the longitudinal direction from the front half of the other side surface of the harness exterior member 60. The front half of 60 is smoothly bent toward the extra length absorbing device 24 in the sliding door with a smaller radius than the rear half. That is, the harness exterior member 60 is bent to a small diameter on the slide door side.
[0035]
When the slide door 2 of FIG. 5 is fully opened, the wide convex ridges 63 inside the bend immediately contact with each other at a small angle bent by a small gap in the narrow groove 64 as shown in FIG. As a result, the harness exterior member 60 is bent in the other direction with a large bending radius. At this time, the ordinary convex strip 61 and the concave groove 62 outside the bend are opened by a small force due to their arc shape, and the bend is smoothly performed.
[0036]
4 and 5, the excess length absorbing device 24 absorbs the excess length by urging the wire harness 5 upward by a leaf spring (elastic member) in a protector as in the conventional case (see JP-A-2001-354085). ) Or a device in which the reel is urged by a winding spring to take up the surplus length by winding the wire harness 5 or the like is appropriately used.
[0037]
According to the above embodiment, in addition to the effect of preventing the harness exterior member 60 from being worn or damaged due to the interference with the vehicle body 3 and the door trim 2a, an inexpensive harness exterior member is formed by using rubber such as EPDM as a material. 60 can be obtained. Further, the harness exterior member 60 of the same product number can be shared by the left and right slide doors 2, which is economical.
[0038]
In addition, instead of the wide ridge 63 of the harness exterior member 60, the pitch of the ridge 61 of a normal size is reduced to reduce the width of the concave groove 62 between the ridges 61, so that the harness exterior member is reduced. It is also possible to obtain a large bending radius of 60. Further, depending on the usage of the harness exterior member 60, a ridge 61 and a groove 62 of a normal size are provided on one side of the harness exterior member 60, and a ridge 63 which is wide over the entire length on the other side. It is also possible to form only the concave groove 64. Further, in the above embodiment, the narrow concave groove 64 is formed on the outer peripheral side. However, the narrow concave groove (64) is formed on the inner peripheral side, and the convex groove on the inner peripheral side ( 63) It is also possible to make them contact each other. Further, it is also possible to integrally form the harness exterior member 60 using another elastic material or a soft material instead of rubber.
[0039]
In addition, the harness exterior member 60 can be applied to a wiring harness arrangement between a slide door other than an automobile slide door and a body other than a vehicle body, or between a rotary door and a body. It is. In this case, the sliding door or door is referred to as a movable structure, and the vehicle body or body is referred to as a fixed structure.
[0040]
As a use mode other than the power supply to the movable structure (2), when wiring the harness exterior member 60 to, for example, a vehicle body, for example, when wiring the wire harness while bending it with a small radius along the vehicle body, In the case where the wiring having the normal size of the convex portion 61 and the concave groove 62 of the harness exterior member 60 is arranged with the inside being bent, and the wire harness is arranged while being bent with a large radius, the harness exterior member 60 is used. The side having the wide convex ridge 63 and the narrow concave groove 64 is arranged with the inside being bent.
[0041]
Thus, the wire harness can be easily and accurately routed in accordance with the curved routing route of the vehicle body even in blind work. Also in this case, the size and arrangement of the ridges 61 and 63 and the concave grooves 62 and 64 of the harness exterior member 60 are set according to the wiring configuration. The positions of the wide ridge 63 and the narrow groove 64 are not limited to the latter half, but may be set in the first half, the center, or near the center.
[0042]
