BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness protector for converging and fixing a wire harness.

[0002]

2. Description of the Related Art Conventionally, a tape-bound 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, in order to cope with a change in the diameter of the wire harness due to a difference in the grade of the vehicle, that is, a change in the amount of electric wires, for example, a cutout portion for applying a binding tape to a branch portion of the protector is known (actually, there is known). See JP-A-2-26321).

FIG. 5 shows an example. In this protector, a branching portion (wire receiving portion) 2 having a U-shaped cross section and having a height dimension smaller than that of the protector body 1 is integrally formed on one side surface of a protector main body (wire receiving portion) 1 having a U-shaped cross section. And a notch 4 around which the binding tape 3 can be wound.

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

[0005]

However, when a notch is provided in the wire receiving portion as in the above-described conventional example, the strength is reduced by a corresponding amount, and when a large number of wires are used, the wire is easily dropped and the tape is removed. There is a problem that binding work becomes difficult.

In view of the above circumstances, the present invention provides a durable protector which is hard to fall off even when the amount of electric wires is large, can be securely bound regardless of the amount of electric wires, and has high strength. The purpose is to do.

[0007]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention provides a wire harness protector having a wire receiving portion having a concave cross section having a pair of side walls. It is characterized by projecting a wire harness mounting table that is lower in height.

[0008]

In the protector having the above-mentioned structure, when the amount of the electric wire is large, the electric wire is placed on the entire surface of the electric wire receiving portion, and the tape is wound around the electric wire to be bound. When the amount of the electric wires is small, the electric wires are preliminarily bound with a tape and mounted on a mounting table. Thus, the wires can be reliably converged and fixed with the tape regardless of the amount of the wires.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One 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 comprises a protector body (main wire receiving portion) 11 and a branch portion (branched wire receiving portion) 12. The protector body 11 has a concave cross section having a pair of side walls 11A, and a branch portion (branch wire receiving portion) 12 having a height dimension smaller than that of the protector body 11 is integrally provided on one side wall 11A. I have.

The branching portion 12 has a concave cross section having a pair of side walls 12A, and a mounting table 13 having a height lower than the side walls 12A is integrally formed at the center of the inner bottom surface thereof. The width of the mounting table 13 is set to a value on which electric wires can be mounted, and the height thereof 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.

[0013] A flange 14 is provided at the tip of the branch portion 12 to prevent the tape from coming off when the tape is wound.

When the wire harness is converged and fixed to the protector having such a configuration, the main wire harness is housed in the protector body 11 and the protector body 11 is closed.
While the binding tape is wound around from the outside and fixed, the branch wire harness branched from the main wire harness is accommodated in the branch portion 12 from the protector body 11, and the binding tape is similarly wound around 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 the electric wire is small), the wire harness 15 is previously tied with the tape 16 and then placed on the mounting table 13. The tape 17 is wound and fixed from the outside of the branch portion 12 above.

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 evenly placed on the entire surface of the branch portion 12 as it is, and a tape 17 is wound and fixed from outside the branch portion 12.

When the amount of the wire harness 15 is large,
If there is a notch as in the related art, the electric wire is likely to fall off, but since there is no notch in the protector of the present embodiment, the wire harness 15 is stably housed in the space surrounded by both side walls 12A, It is hard to fall off. Therefore, it becomes easy to perform the tape bundling operation.

Further, since there is no notch, and the mounting table 13 is protruded at the center of the inner bottom surface of the branching section 12, the section modulus becomes large and high strength is maintained.

When the upper surface of the mounting table 13 is formed by a concave arcuate surface 18 as in the other embodiment shown in FIG. 4, the small-diameter wire harness 15 can be held in an extremely stable state. Become like

Further, in the above embodiment, the mounting table 13 is provided on the branch portion 12, but may be provided on the inner bottom surface of the protector body 11.

[0021]

As described above, according to the protector of the present invention, even when the amount of the electric wires is large, the electric wires are less likely to fall off, so that the work of binding with the tape is facilitated. In addition, reliable bundling is possible regardless of the amount of electric wires, and high strength can be maintained. That is, since the wire harness mounting table is provided over the base where the wire receiving portion protrudes from the protector main body, when supporting the wires, the base of the wire receiving portion where stress concentration is likely to occur can be reinforced. In addition, the electric wire can be held at a high strength and in an extremely stable state.
