Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wire harness protector that converges and fixes a wire harness.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, a tape binding type protector has been used to converge and fix a branch portion of a wire harness when wiring an automobile or the like. In this case, for example, it is known that a protector is provided with a cutout portion for applying a binding tape to the change in the diameter of the wire harness, that is, the change in the amount of electric wires, depending on the grade of the vehicle. (See Japanese Utility Model Laid-Open No. 2-26321).

FIG. 5 shows an example thereof. This protector has a branch portion (electric wire receiving portion) 2 of the same U-shaped cross-section whose height dimension is set smaller than that of the protector body 1 on one side surface of the protector main body (electric wire receiving portion) 1 having a U-shaped cross section. Has a notch 4 around which the binding tape 3 can be wound around the tip of the branch 2.

According to this, as shown in FIG. 6, when the amount of the branch electric wire 5 is small, the binding tape 3 is wound around the notch 4 to securely fix the branch electric wire 5 to the protector with the binding tape 3. be able to. Further, as shown in FIG. 7, when the amount of the branch electric wire 5 is large, the binding tape 3 is wound around the base end portion of the branch portion 2 instead of the notch portion 4, so that the branch electric wire 5 is surely fixed to the protector. be able to. Therefore, the wire harness can be reliably converged and fixed regardless of the amount of the branch electric wire 5.

[0005]

[Problems to be solved by the device]

 By the way, when a notch is provided in the wire receiving part as in the above-mentioned conventional example, the strength is reduced, and when the number of wires is large, the wires easily fall off and the tape binding work becomes difficult. There is.

In consideration of the above-mentioned circumstances, the present invention is such that even when the amount of electric wires is large, the electric wires are unlikely to drop off, and reliable bundling can be performed regardless of the amount of electric wires, and a strong and durable prote Kuta is intended to provide.

[0007]

[Means for Solving the Problems]

 In view of the above circumstances, the present invention provides a protector for a wire harness including a wire receiving portion having a concave cross-section having a pair of side walls, the wire harness having a lower height than the side wall on the inner bottom surface of the wire receiving portion. The feature is that the mounting table is projected.

[0008]

[Action]

 In the protector having the above structure, when the amount of the electric wire is large, the electric wire is put on the entire surface of the electric wire receiving portion as it is, and the tape is wound to bind the electric wire. Also, when the amount of electric wires is small, the electric wires are bundled with tape beforehand and then placed on the mounting table, and then the electric wire receiving part is bundled with tape. This makes it possible to reliably bundle and fix the wires with the tape regardless of the amount of the wires.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a main part of a protector according to an embodiment of the present invention.

This protector includes a protector body (main wire receiving portion) 11 and a branch portion (branching wire receiving portion) 12. The protector main body 11 has a concave cross-section having a pair of side walls 11A, and one side wall 11A is integrally provided with a branch portion (branch wire receiving portion) 12 whose height dimension is set smaller than that of the protector main body 11. ing.

The branch portion 12 has a concave cross section having a pair of side walls 12A, and a mounting table 13 having a height lower than that of the side walls 12A is integrally projectingly provided at the center of the inner bottom surface thereof. The width of the mounting table 13 is set to a value at which an electric wire can be mounted, and its height is set smaller than the height of the side wall 12A. In this example, the upper surface of the mounting table 13 is a flat surface.

A flange portion 14 is provided at the tip of the branch portion 12 so as not to come off when the tape is wound.

When the wire harness is converged and fixed to the protector having such a structure, the main wire harness is housed in the protector main body 11 and the binding tape is wound from the outside of the protector main body 11 to be fixed. The branch wire harness branched from the wire harness is housed in the branch portion 12 from the protector main body 11, and similarly, the binding tape is wound from the outside of the branch portion 12 and fixed.

At this time, as shown in FIG. 2, when the diameter of the branch wire harness 15 is small (the amount of electric wires is small), the wire harness 15 is bound in advance with the tape 16 and placed on the mounting table 13, and The tape 17 is wound from the outside of the branch portion 12 and fixed.

Further, as shown in FIG. 3, when the diameter of the branch wire harness 15 is large (the amount of electric wires is large), the wire harness 15 is placed on the entire surface of the branch portion 12 as it is, and the The tape 17 is wound and fixed from the outside.

When the wire harness 15 is large in quantity, the electric wire is likely to fall off if there is a cutout portion as in the conventional case. However, since the protector of this embodiment has no cutout portion, it is surrounded by both side walls 12A. The wire harness 15 is stably accommodated in the space and is hard to fall off. Therefore, the tape binding work is facilitated.

Moreover, since the mounting table 13 is provided at the center of the inner bottom surface of the branch portion 12 in addition to having no cutout portion, the section modulus becomes large and high strength is maintained.

As in the other embodiment shown in FIG. 4, when the upper surface of the mounting table 13 is formed by the concave arc surface 18, the wire harness 15 having a small diameter can be held in an extremely stable state. become able to.

In addition, in the above-described embodiment, the mounting table 13 is provided at the branch portion 12, but it may be provided at the inner bottom surface of the protector body 11.

[0021]

[Effect of device]

 As described above, according to the protector of the present invention, even when the amount of the electric wire is large, the electric wire is less likely to fall off, and thus the tape bundling work is facilitated. In addition, reliable bundling is possible regardless of the amount of electric wires, and high strength can be maintained.
