[0003] [Patent Document 1] JP 2017-192266 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the clamp of the prior art has a flat base plate and a first bent piece and a second bent piece at both ends of the base plate in the longitudinal direction, and the first bent piece and the second bent piece are deformed to fit the outer shape of the wiring material, and a tape member is wound around the wiring material from the first bent piece and the second bent piece to fix it. In this configuration, the contact area between the wiring material and the clamp is reduced, so that the wiring material and the clamp are not sufficiently fixed, and the clamp is likely to be misaligned with respect to the wiring material. Therefore, when the wire harness is assembled to the vehicle, the positions of the through hole and the clamp do not match, making assembly difficult, and there is room for improvement in terms of workability.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a wire harness and a clamp that can prevent the clamp from shifting from the position relative to the wiring material, thereby ensuring proper workability. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the clamp of the present invention comprises a clip that fits into a through hole formed in a vehicle body, and a routing portion formed in a flat plate shape and in which a wiring material is routed along the longitudinal direction of the plate, the routing portion having a base portion in which a routing surface for the wiring material is formed on the surface of the flat plate opposite the clip, and sleeve portions provided on both longitudinal ends of the base portion and to which fixing members are attached, the routing surface of the base portion being provided at a different position in the height direction intersecting the longitudinal direction with respect to the sleeve portion, the wiring material being routed on the routing surface, and the fixing member being wrapped around the sleeve portion, the wiring material being sandwiched and fixed between the sleeve portion and the fixing member. Effect of the Invention

[0008] According to the wire harness and clamp of the present invention, the wiring part has a base part in which a wiring surface of the wiring material is formed on the surface opposite to the clip in the flat plate, and sleeve parts provided at both ends of the longitudinal direction of the base part, to which fixing members are attached, and the wiring surface of the base part is provided at different positions in the height direction intersecting the longitudinal direction with respect to the sleeve part, and the wiring material is wired on the wiring surface and the fixing member is wrapped around the sleeve part, and the wiring material is sandwiched and fixed between the sleeve part and the fixing member, so that the position of the clamp can be prevented from shifting relative to the wiring material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

Fig. 5 is a side cross-sectional view of the wire harness according to the present embodiment cut along a plane perpendicular to the axis of the wiring material, and shows a state in which the fixing band is fastened. In Figs. 1 to 3, the wire harness is shown in a state before the fixing band is occupied.

[0012] The wire harness WH of this embodiment has a wiring material W used for power supply and signal communication for connecting each device mounted on a vehicle, and the wiring material W is connected to each device via a connector or the like. As shown in FIG. 1, the wire harness WH includes, for example, a conductive wiring material W, a clamp 1 supporting the wiring material W, and a fixing band 2 (fixing member) provided at each end of the clamp 1 in the longitudinal direction and fixing the clamp 1 to the wiring material W. The wire harness WH may further include various components such as an exterior member such as a corrugated tube or a protector, and an electric connection box. In the following description, the first direction of the first direction, the second direction, and the third direction intersecting each other are referred to as the "longitudinal direction X", the second direction as the "width direction Y", and the third direction as the "height direction Z". The longitudinal direction X, the width direction Y, and the height direction Z are typically perpendicular to each other. Here, the longitudinal direction X corresponds to the longitudinal direction of the clamp 1 described above. Further, the width direction Y corresponds to the width direction of a wiring portion 12 of the clamp 1, which will be described later, and the height direction Z corresponds to the height direction of this wiring portion 12.

[0013] The wiring material W is composed of, for example, a metal rod, an electric wire, a bundle of electric wires, etc. A metal rod is a rod-shaped member having electrical conductivity, the outside of which is covered with an insulating covering. An electric wire is a conductor (core wire) made of a plurality of conductive metal strands, the outside of which is covered with an insulating covering. A bundle of electric wires is a bundle of these electric wires. In the example of FIG. 1, the wire harness WH includes one wiring material W, but is not limited to this and may be configured to include a plurality of wiring materials.

[0014] The clamp 1 includes a clip 11 that fits into a through hole formed in the vehicle body, and a wiring portion 12 in which the above-mentioned wiring material W is routed. In this embodiment, the clip 11 and the wiring portion 12 are integrally molded from the same resin material (for example, a thermoplastic resin such as polypropylene or nylon). This configuration makes it possible to easily manufacture the wiring portion 12 that supports the wiring material W.

[0015] The clip 11 is provided at the center of the longitudinal direction X of the wiring portion 12. The clip 11 includes an elliptical base 20 with a major axis extending in the longitudinal direction X of the wiring portion 12, a support 21 protruding from the base 20 in the height direction Z, and a pair of arms 22 joined to the ends of the support 21. The arms 22 each extend from the end of the support 21 toward the base 20 side so as to widen in the longitudinal direction X, and are elastically deformable with the joint with the support 21 as a fulcrum. In addition, a locking step 22A is provided at the end of each of the arms 22. As shown in FIG. 2 and FIG. 3, when the clip 11 is inserted into a through hole 51 formed in a mounting panel 50 of the vehicle body, the locking step 22A of the arm 22 is locked to the periphery of the through hole 51, so that the clip 11 is fitted into the through hole 51.

[0016] The wiring portion 12 is formed in a flat plate shape and wires the wiring material W along the longitudinal direction X of the flat plate. Specifically, as shown in FIG. 4, the wiring portion 12 includes a base portion 31 formed in a flat plate shape and sleeve portions 32 provided at both ends of the base portion 31 in the longitudinal direction X. The sleeve portions 32 are portions to which the fixing bands 2 (see FIG. 1) are attached to fix the wiring material W. The sleeve portions 32 include ribs 33 extending in the width direction Y at both ends of the surface 32A on the clip 11 side. The ribs 33 protrude in the height direction Z from the surface 32A on the clip 11 side, and prevent the fixing band 2 from falling off the sleeve portions 32. The sleeve portions 32 also have a fixing surface 32B located on the opposite side to the surface 32A on the clip 11 side, and the wiring material W is fixed to the fixing surface 32B by the fixing band 2.

[0017] The fixing band 2 is a so-called cable tie. As shown in FIG. 1, the fixing band 2 is attached to each sleeve portion 32 to fix the wiring portion 12 (sleeve portion 32) to the wiring material W. The fixing band 2 includes a main body portion 41 and a band 42 extending from the main body portion 41. The main body portion 41 is formed with a hole portion (not shown) through which the band 42 can pass, and a locking claw (not shown) protrudes from the inner surface into the hole portion. A locking groove that engages with the locking claw formed in the main body portion 41 is continuously provided on the surface of the band 42. In this embodiment, in the direction in which the band 42 is inserted into the main body portion 41, the locking claw and the locking groove are disengaged, allowing the fixing band 2 to be inserted. On the other hand, in the direction in which the band 42 is removed from the main body portion 41, the locking claw is engaged with the locking groove and is not released, so that the band 42 cannot be removed (loosened).

[0018] Incidentally, the wiring portion 12 includes the base portion 31 formed in a flat plate shape as described above. The clip 11 is provided in the center of the longitudinal direction X on one surface 31A of the base portion 31. The other surface 31B (the surface opposite to the clip) of the base portion 31 is the wiring surface on which the wiring material W is wired. As shown in FIG. 4, the other surface 31B is formed at a different position in the height direction Z from the fixed surface 32B of the sleeve portion 32. More specifically, the fixed surface 32B of the sleeve portion 32 and the other surface 31B of the base portion 31 are formed in a stepped shape, and the fixed surface 32B of the sleeve portion 32 is formed at a position closer to the clip 11 in the height direction Z than the other surface 31B of the base portion 31.

[0019] Moreover, the sleeve portion 32 is formed narrower than the base portion 31. That is, as shown in Fig. 4, the length L1 in the width direction Y of the sleeve portion 32 is formed smaller than the length L2 in the width direction Y of the base portion 31. More specifically, as shown in Fig. 5, the length L1 in the width direction Y of the sleeve portion 32 is set to be equal to or larger than 1 / 2 of the diameter D of the wiring material W, and is preferably set to be equal to or smaller than the diameter D of the wiring material W. That is, it is preferable that the length L1 in the width direction Y of the sleeve portion 32 and the diameter D of the wiring material W satisfy the relationship D / 2≦L1≦D.

[0020] In this embodiment, the wiring material W is routed along the longitudinal direction X of the base portion 31 of the wiring section 12, and then sequentially fixed to the sleeve portions 32 provided at both ends of the base portion 31 by the fixing bands 2. According to this configuration, the wiring material W extends along the shape of the base portion 31 and the sleeve portion 32 of the wiring section 12 formed in a stepped shape as shown in Figs. 2 and 3, and is routed on the other surface 31B of the base portion 31 and fixed to the fixing surface 32B of the sleeve portion 32 at a different height position relative to the other surface 31B. Therefore, the wiring material W is shaped into a rectangular shape (step-like) and routed and fixed to the wiring section 12 (clamp 1), so that the positional deviation of the clamp 1 with respect to the wiring material W can be prevented.

[0021] In this embodiment, the length L1 of the sleeve portion 32 in the width direction Y is smaller than the length L2 of the base portion 31 in the width direction Y. Therefore, as shown in FIG. 5, when the fixing band 2 is wrapped around the outside of the sleeve portion 32 and the fixing band 2 is tightened and fixed in a state in which the wiring material W is wired in the wiring portion 12, the contact area between the fixing band 2 and the wiring material W increases, so that the wiring material W can be firmly fixed to the clamp 1. Furthermore, in the direction in which the fixing band 2 is pulled out from the main body portion 41, the locking claws of the fixing band 2 are engaged with the locking grooves and are not released, so that the state in which the clamp 1 is fixed to the wiring material W is maintained. Therefore, when the wire harness WH is assembled to the vehicle, the position of the clip 11 of the clamp 1 relative to the through hole 51 of the mounting panel 50 can be accurately determined, and appropriate workability can be ensured.

[0022] As described above, the wire harness WH and the clamp 1 of this embodiment include the clip 11 that fits into the through hole 51 formed in the mounting panel 50 of the vehicle body, and the routing portion 12 that is formed in a flat plate shape and in which the routing material W is routed along the longitudinal direction X of the flat plate. The routing portion 12 has a base portion 31 that serves as the routing surface for the routing material W on the other surface 31B opposite the clip 11, and sleeve portions 32 that are provided on both ends of the longitudinal direction X of the base portion 31 and to which the fixing bands 2 are attached. The other surface 31B of the base portion 31 is provided at a different height position in the height direction Z compared to the sleeve portion 32. The routing material W is routed on the other surface 31B of the base portion 31, and the routing material W is fixed by being sandwiched between the sleeve portion 32 and the fixing band 2 with the fixing band 2 wrapped around the sleeve portion 32. Therefore, the wiring material W extends along the shape of the base portion 31 and sleeve portion 32 of the wiring portion 12 formed in a stepped shape, and is shaped into a rectangular shape (stepped shape) and fixed to the clamp 1, thereby preventing the clamp 1 from shifting in position relative to the wiring material W. Therefore, the wire harness WH and the clamp 1 of this embodiment can accurately determine the position of the clip 11 of the clamp relative to the through hole 51 of the mounting panel 50, and have the effect of preventing the clamp from shifting in position relative to the wiring material when assembling the wire harness WH to a vehicle, and ensuring proper workability.

[0023] In the wire harness WH and clamp 1 of this embodiment, the sleeve portion 32 is formed so that its length L1 in the width direction Y is smaller than the length L2 in the width direction Y of the base portion 31. Therefore, when the wiring material W is arranged in the wiring portion 12, and the fixing band 2 is wrapped around the outside of the wiring material W and the sleeve portion 32 and the fixing band 2 is tightened and fixed, the contact area between the fixing band 2 and the wiring material W increases, so that the wiring material W can be firmly fixed to the clamp 1.

[0024] In the wire harness WH and the clamp 1 of this embodiment, the length L1 of the sleeve 32 in the width direction Y is set to be equal to or greater than 1 / 2 of the diameter D of the wiring material W. Therefore, while ensuring the rigidity of the sleeve 32, the contact area between the fixing band 2 and the wiring material W increases when the fixing band 2 is wrapped around the outside of the wiring material W and the sleeve 32 and the fixing band 2 is tightened and fixed, so that the wiring material W can be firmly fixed to the clamp 1.

[0025] In the wire harness WH and the clamp 1 of this embodiment, the sleeve portion 32 has a rib 33 extending in the width direction Y at the end in the longitudinal direction X, thereby preventing the fixing band 2 wrapped around the outside of the sleeve portion 32 together with the wiring material W from falling off.

[0026] The wire harness and the clamp according to the embodiment of the present invention described above are not limited to the above-mentioned embodiment, and various modifications are possible within the scope of the claims. For example, in the above description, as an example in which the other surface 31B of the base portion 31 is formed at a different position in the height direction Z with respect to the fixing surface 32B of the sleeve portion 32, a configuration in which the fixing surface 32B of the sleeve portion 32 is formed at a position closer to the clip 11 in the height direction Z than the other surface 31B of the base portion 31 is exemplified, but this is not limited thereto, and the fixing surface 32B of the sleeve portion 32 may be formed at a position farther from the clip 11 in the height direction Z than the other surface 31B of the base portion 31. In the above description, a fixing band is exemplified as a fixing member for fixing the wiring portion of the clamp to the wiring material, but this is not limited thereto, and for example, an adhesive tape (fixing member) may be wound around the outside of the wiring portion to fix it. In the above description, the wiring material is described as an electric wire having conductivity, but this is not limited thereto. [Explanation of symbols]
