Description

  The present invention relates to a wire harness flattening band configured to flatten a part of a linear body including a wire bundle of a wire harness and to be locked to, for example, a vehicle panel or the like.

Below, the wiring structure of the wire harness disclosed by the following patent document 1 is demonstrated.
The wire harness W / H routed in the vehicle includes a portion Sa covered by the grommet tube portion 30 as shown in FIG. 16 and a portion Sb covered by the bellows portion 31 as shown in FIG. I have.

  And using the protector 35 as shown in FIG. 17, the part Sa coat | covered with the cylinder part 30 was changed into a flat shape, and was fixed to the vehicle panel etc. Thus, by flattening the wire harness W / H, the wire harness W / H can be routed even in a narrow space.

  The protector 35 connects the main body portion 36 and the lid portion 37 via a thin hinge 38, and a locking claw (not shown) provided at one end of the lid portion 37 is connected to the end portion of the lower side portion 36 a of the main body portion 36. It is the structure which latches to. Further, a clip 39 for fixing the protector 35 to a vehicle panel or the like is provided at the lower end of the lower side portion 21a.

When flattening the wire harness W / H, the lid portion 37 is rotated clockwise in FIG. 17 about the hinge 38 to open one side surface of the main body portion 36. Next, the wire harness W / H is inserted into the main body portion 36, the lid portion 37 is closed, and the wire harness W / H is flattened and integrated with the protector 35 as shown in FIG.
JP 2004-236447 A

  However, the wire harness wiring structure requires a protector 35 to flatten the wire harness W / H. For this reason, a space for the protector 35 is required at a position where the wire harness W / H is desired to be flattened. Therefore, when there is no space for housing the protector 35, it is difficult to flatten and wire the wire harness W / H.

  In addition, since various types of protectors are required in accordance with the difference in shape such as the length and thickness of the wire harness W / H, there is a problem that various molds must be prepared for manufacturing the protectors.

  The present invention has been made in view of the above problems, and its object is to flatten the desired position of the wire harness without using a special member such as a protector, and to facilitate the wiring. An object of the present invention is to provide a wire harness flattening band configured so as to be able to suppress the deviation.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.
1 is a perspective view showing a configuration of a wire harness flattening band according to a first embodiment of the present invention, FIG. 2 is a perspective view showing flattening of a wire harness, and FIG. It is sectional drawing which shows flattening and the fixed state to a clamp.

  As shown in FIGS. 1 to 3, a wire harness flattening band (hereinafter abbreviated as a band) 1 has a linear body of a wire harness 3 on a substrate 2 formed in a rectangular plate shape. A wire harness fixing portion 4 having a plate portion for fixing (electric wires or the like) 9 and a locking tool 5 for locking the substrate portion 2 to a vehicle panel (hereinafter abbreviated as a panel) or the like. It is provided integrally. The band 1 may have a configuration in which the locking tool 5 is omitted.

  A through hole 6 is formed in a substantially central portion of the substrate portion 5 in the longitudinal direction, and a binding band 7 is inserted into the through hole 6. The binding band 7 includes a locking portion 7a and a band portion 7b. The locking portion 7a is provided with an insertion hole 8a, and a locking claw (not shown) is provided therein.

  On the other hand, the band portion 7b is provided with a plurality of locking holes 8b. By inserting the band portion 7b into the insertion port 8a, a locking claw (not shown) locks the locking hole 8b and cannot be pulled out. It is configured as follows.

  The wire harness 3 is formed by bundling a plurality of linear bodies 9 in a substantially circular cross section as shown at the right end of FIG. 2, and the surface thereof is covered with a deformable protective member 9a.

  The locking tool 5 includes a flange portion 12 that is open in the shape of a shade, a shaft portion 13 that protrudes from a central portion thereof, and a locking portion 14 that is elastically deformable.

  On the other hand, as indicated by an imaginary line in FIG. 3, an insertion hole 11 a is formed in the panel 11. And when fixing the said band 1 to the panel 11, the lower end part of the latching | locking part 14 is inserted in the insertion hole 11a, and it continues pushing in as it is. By continuing the pushing, the diameter of the locking portion 14 is reduced, and when the locking portion 14 passes through the insertion hole 11a, the original shape is elastically restored. As a result, the panel 11 is sandwiched between the flange portion 12 and the locking portion 14, and the entire band 1 is fixed to the panel 11.

Next, the flattening of the wire harness 3 and the clamping action on the panel 11 such as a vehicle will be described.
First, the binding band 7 is inserted into the through hole 6, and the locking portion 7 a and the band portion 7 b are extended to both sides of the wire harness fixing portion 4.

  Next, the bundle-like linear body 9 of the wire harness 3 is placed on the wire harness fixing portion 4, and the linear body 9 of the wire harness 3 is previously crushed with both fingers and deformed into an elliptical cross section. It is preferable to place it while doing so. Following this operation, the band portion 7 b is hung on the wire harness 3, the tip end portion of the band portion 7 b is inserted into the insertion port 8 a, the tip end portion is gripped and pulled strongly, and the wire harness 3 is pulled by the binding band 7. The linear body 9 is tightened.

  As a result, the entire linear body 9 of the wire harness 3 is strongly pressed against the wire harness fixing portion 4. Since the surface of the wire harness fixing portion 4 is planar, the linear body 9 of the wire harness 3 extends in the width direction along the surface shape, and is flattened as shown in FIGS.

  At a position where the linear body 9 of the wire harness 3 is flattened, a locking claw provided in the locking portion 7a locks one of the plurality of locking holes 8b. Even if the force pulling the band portion 7b at this time is released, the binding band 7 is not loosened, and the wire harness 3 is flattened and fixed to the band 1 at the same time.

  As described above, after the linear body 9 of the wire harness 3 is fixed to the wire harness fixing portion 4, the lower end of the locking portion 14 is inserted into the insertion hole 11a formed in the panel 11 as described above, and is pushed in as it is. Band 1 is fixed to panel 11.

  That is, in this embodiment, the linear body 9 of the wire harness 3 is fixed to the wire harness fixing portion 4 using the binding band 7, so that the linear body 9 of the wire harness 3 is placed on the surface of the wire harness fixing portion 4.
