DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tying tool used for, for example, tying a wire harness housed in a protector.

[0002]

2. Description of the Related Art Conventionally, as this type of tying tool, there is, for example, one shown in FIGS. 5 and 6 described in Japanese Utility Model Laid-Open No. 2-103719.

As shown in FIG. 5, this binding device uses a flexible band clamp 30 to bind the wire harness 20 housed in the protector 10. As shown in FIG. 6, a band lock 32 is integrally provided at the base end of the band clamp 30. A serrated engagement portion 34 is formed on the inner surface of the free end of the band clamp 30. In addition, the band lock 32 includes
Insertion hole 36 through which the free end of band clamp 30 is inserted
And an engagement arm 38 provided with an engagement projection 38a with which the engagement portion 34 engages.

[0004] In order to bind the wire harness 20 using the band clamp 30, first, the wire harness 20 is moved along a harness fixing rib 14 provided at one longitudinal end of the bottom plate 12 of the protector 10, and then, Then, the band clamp 30 is pulled out from the lower surface of the harness fixing rib 14 to the other end thereof, is hooked on the wire harness 20, and the free end of the band clamp 30 is inserted into the insertion hole 36 of the band lock 32.
And the engaging portion 34 is engaged with the locking projection 38a to be locked. Thereby, the wire harness 20 is bound and fixed on the harness fixing rib 14.

[0005]

However, in the above-described conventional tying tool, after the wire harness 20 is fixed on the wire fixing rib 14 by the band clamp 30, the wire harness 20 is displaced in the axial direction. As a result, the band clamp 30 may be displaced and come off from the wire fixing rib 14.

Therefore, it is conceivable to provide a band fixing member 40 as shown in FIG. This band fixing member 4
Numeral 0 is provided integrally with one side of the wire fixing rib 14 of the protector 10 and has an insertion hole 42 through which the band clamp 30 is inserted.

When the wire harness 20 is bound, the band clamp 30 is inserted into the insertion hole 42 of the band fixing member 40, the wire harness 20 is hung from the lower surface of the harness fixing rib 14, and the free end is connected to the band. The engaging portion 34 is inserted into the insertion hole 36 of the lock 32 to
Lock by engaging with a.

According to this binding device, the wire harness 20
After banding, the band clamp 30 is
Since the band clamp 30 is fixed by zero, displacement of the band clamp 30 is prevented, and the band clamp 30 does not come off from the wire fixing rib 14.

However, in this binding device, when attaching and detaching the band clamp 30, the insertion hole 42 of the band fixing member 40 is used.
However, there is a problem that the detachability is poor and the workability is reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tying member which can prevent the band clamp from being displaced in consideration of the above circumstances and can easily attach and detach the band clamp.

[0011]

In order to solve the above-mentioned problems, the present invention provides a wire harness along a harness fixing rib provided at one longitudinal end of a bottom plate of a protector.
In a binding device to be bound by a flexible band clamp, a band fixing member having a U-shaped cross section having an opening on the protector side is provided on one side of the harness fixing rib, and the harness fixing rib is provided. In addition, a notch is formed in the vicinity of the opening.

[0012]

In the binding device having the above-mentioned structure, the band fixing member prevents displacement of the band clamp after the binding of the wire harness, so that the band clamp does not come off from the wire fixing rib.

Further, by displacing the band clamp in the axial direction from the opening of the band fixing member and transmitting the band clamp to the notch, the band clamp is loosened, so that the band clamp can be easily attached and detached.

[0014]

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

FIG. 1 is a perspective view of a binding device according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line II-II of FIG. In these figures, the same components as those in FIG. 5 are denoted by the same reference numerals, and description thereof will be omitted.

In this binding device, the band fixing member 5 for fixing the band clamp 30 after binding the wire harness 20 is used.
0 is newly provided.

The band fixing member 50 is formed to have a U-shaped cross section having an opening 52, and the bottom plate 1 of the protector 10 is formed.
2 harness fixing rib 14 provided at one longitudinal end
The opening 52 is provided integrally with the protector 10 on one side.

A notch 16 is formed in the harness fixing rib 14 at a position near the opening 52.

Next, the operation of the embodiment will be described.

Harness fixing rib 14 of protector 10
The band clamp 30 is inserted into the band fixing member 50 through the opening 52, pulled out from the lower surface of the harness fixing rib 14 to the other end, and hooked on the wire harness 20, and the free end of the band clamp 30 is The part is inserted into the insertion hole 36 of the band lock 32, and the engaging part 34 is engaged with the locking projection 38a to lock. Thereby, the wire harness 20 is bound and fixed on the harness fixing rib 14.

The band clamp 30 after binding the wire harness 20 is fixed by a band fixing member 50. Therefore, the band clamp 30 is prevented from being displaced by the band fixing member 50 and does not come off from the wire fixing rib 14.

When the band clamp 30 is detached after the wire harness 20 is bound, for example, to increase or decrease the number of the wire harness 20, the band clamp 30 is first attached to the band fixing member 50 as shown in FIGS.
The protector 10 extends laterally (axially) from the opening 52 of the protector 10.
Notch 1 formed on wire fixing rib 14 shifted to the side
Position 6 When the band clamp 30 is positioned in the cutout portion 16 in this manner, the band clamp 30 is loosened, so that the band clamp 30 is easily removed. Therefore, the band clamp 30 can be easily attached and detached, and workability is improved.

[0023]

As described above, according to the present invention,
Since the displacement of the band clamp can be prevented by the band fixing member, the band clamp does not come off from the wire fixing rib.

Further, the band clamp can be loosened by shifting the band clamp after binding the wire harness from the opening of the band fixing member in the axial direction to the notch, so that the band clamp can be easily attached and detached. Therefore, workability can be improved.
