Japanese Patent No. 3538688 JP-A-9-250515

  By the way, in recent years, with the increase in in-vehicle electronic components, the number of electric wires 104 accommodated in the wire harness 103 has increased, and the cross-sectional shape of the wire harness 103 is elliptical as shown in FIG. May form.

  In the conventional wire harness band 101, since the mounting plate portion 111 is flat, in a state where the elliptical cross-section wire harness 103 is mounted on the surface 112 of the mounting plate portion 111, as shown in FIG. A gap 107 is formed between the curved surface of the wire harness 103 and the surface 112 of the mounting plate portion 111.

  On the other hand, in order to mount the wire harness 103 having an elliptical cross section, the length of the mounting plate portion 111 in the direction orthogonal to the axis of the wire harness 103 is set to be larger, and the mounting plate portion 111 has bending rigidity than the conventional one. Low.

  For this reason, when tightening is performed using the binding band portion 121, as shown by an arrow B in FIG. 26, the mounting plate portion 111 is bent along the outer periphery of the wire harness 103. The bending of the mounting plate portion 111 may cause distortion in the mounting portion 141 and may cause a trouble in fixing to the structure.

  As a measure for avoiding the above problems, there is a method of increasing the overall rigidity of the mounting plate portion 111 to increase the bending rigidity of the mounting plate portion 111. The plate portion 111 needs to be considerably thickened, which causes a problem that the mounting plate portion 111 is increased in weight.

  Accordingly, an object of the present invention is to solve the above-described problems, and the placement plate portion on which the wire harness is placed is prevented by preventing the placement plate portion from bending along the curvature of the outer periphery of the wire harness. To provide a wire harness band that can prevent the fixing to a structure from being hindered due to the influence of bending of the wire harness and that can also suppress weight increase due to an increase in the plate thickness of the mounting plate portion described above. It is in.

The above-described object of the present invention is achieved by the following configuration.

The movement of the harness in the axial direction can be firmly regulated.

  According to the configuration of (6) above, the plurality of cone-shaped protrusions provided on the placement plate portion are two rows, one row on each side of the placement center line, and on the cross section of the wire harness. The contact to the mounting plate portion is a three-point contact, ie, a contact with two rows of cone-shaped projections and a direct contact with the mounting plate portion on the mounting center line. The wire harness can be efficiently fixed while being suppressed. In other words, the structure of the mounting plate portion can be simplified by suppressing the number of equipment of the cone-shaped projections.

  According to the wire harness band according to the present invention, when the wire harness having an elliptical cross section is placed on the placement plate portion, the gap between the outer peripheral surface of the wire harness and the surface of the placement plate portion is the circumferential surface. It is filled with a supporting protrusion. Therefore, even if the binding band portion wound around the wire harness on the placement plate portion is tightened, it is possible to prevent the placement plate portion from bending along the outer periphery of the wire harness. Therefore, in the case of having the mounting portion, it is possible to prevent the mounting portion from being distorted (deformed) due to the influence of the bending of the mounting plate portion, and the fixing to the structure is hindered by the distortion of the mounting portion. It can be prevented from occurring.

  In addition, the peripheral support protrusion may be provided on a part of the surface of the mounting plate portion, and it is not necessary to increase the overall thickness of the mounting plate portion. Therefore, weight increase due to an increase in the thickness of the mounting plate portion can be suppressed.

  In the wire harness band 1E of the sixth embodiment, a plurality of cone-shaped projections 51C provided on the mounting plate portion 11 are arranged on both sides of the mounting center line 13 one by one along the axial direction of the wire harness. As shown in FIG. 21, the contact with the mounting plate portion 11 on the cross section of the wire harness 103 includes the contacts Q1 and Q2 with respect to the two rows of conical projections 51C and the mounting center. It becomes a three-point contact with the direct contact Q3 to the mounting plate part 11 on the line 13, and it becomes possible to fix the wire harness 103 efficiently while suppressing the number of equipment of the conical projections 51C. In other words, the structure of the mounting plate part 11 can be simplified by suppressing the number of equipment of the conical projections 51C.

  In addition, the band for wire harnesses of the present invention is not limited to the above-described embodiments, and appropriate modifications and improvements can be made. In addition, the material, shape, dimensions, form, quantity, location, etc. of each component of the wire harness band of the present invention are arbitrary as long as the object of the present invention can be achieved. It is not limited.
