2. Description of the Related Art Generally, a corrugated tube used for focusing and protecting a wire group such as a transmission / distribution wire of an electronic device or a wire harness of an automobile is a spiral or annular protrusion on the outer circumference of a tube made of synthetic resin. Flexibility is imparted by continuously forming the ridges and forming a bellows shape. Then, for example, as shown in FIG. 11, the corrugated tube 30 is
In order to protect the wire harness W / H, which is a group of electric wires, over a predetermined area, the slit 31 formed to extend in the longitudinal direction is spread to be mounted on the wire harness W / H, and at the end thereof. By winding the adhesive tape T together with the wire harness W / H, it is positioned and fixed at a predetermined position.

Further, Japanese Utility Model Laid-Open No. 62-145426 discloses a "corrugated tube end locking device". As shown in FIG. 12, the terminal locking device 40 of this corrugated tube has a locking portion 4 in which two half members 44 connected to each other by a hinge 42 are equipped at their free ends.
It is provided so that it can be attached to the outer periphery of the corrugated tube 30 by engaging 6 with each other.

When the terminal locking device 40 is attached to the corrugated tube 30, the terminal locking device 40 projects from the inner wall of the half-split member 44 so as to protrude from the inner ring of the corrugated tube 30.
3 and the ridge portion 33 formed between the ridge portion 33 and the protrusion 48, which protrudes inward at an outer position separated from the protrusion 48 by a predetermined distance, and the wire harness W / H
And a plurality of rotation preventing protrusions 50 that engage with or interfere with each other. By attaching such a terminal locking member 40, it is possible to prevent the opening of the slit 31 of the corrugated tube 30 and the rotation of the corrugated tube 30 around the harness.

[0005]

However, as shown in FIG.
As shown in Figure 3, tape-wrap the corrugated tube 3
When 0 is positioned and fixed at a predetermined position, there is a problem that labor and labor are required because the tape is wound manually. Furthermore, when the outer diameter of the wire harness W / H is thin enough to have a gap with respect to the inner diameter of the corrugated tube 30, for example, after winding the adhesive tape T to an appropriate diameter, the corrugated tube 30 is attached. Since it has to be attached, it takes more time, and at the same time, the amount of tape used increases and the manufacturing cost rises.

Further, in the corrugated tube end locking device 40 shown in FIG. 12, as described above, the opening of the slit 31 of the corrugated tube 30 and the rotation of the corrugated tube 30 around the harness are prevented. However, it is not sufficient as a positioning means for preventing the corrugated tube 30 from moving in the axial direction on the harness. Therefore, the wire harness W / H
In the installation work, the corrugated tube 30 to be externally mounted, for example, to prevent contact with other parts, may be displaced from a predetermined position, and may not be able to exhibit its intended function.

Therefore, an object of the present invention is to solve the above-mentioned problems. The corrugated tube can be positioned and fixed at a predetermined position on the wire group by a simple operation and can be applied to wire groups of any thickness. Another object is to provide a clip for a corrugated tube.

[0008]

The above object of the present invention is a corrugated tube clip for positioning and fixing a corrugated tube in which a wire group is inserted at a predetermined position of the wire group, the end portion of the corrugated tube being provided. A tube fixing part that fits and holds the outer peripheral surface and a wire holding part that bends and holds the wires of the wire group exposed from the end of the tube in parallel in a row are openably and closably connected via a hinge. The clip body for a corrugated tube, which is integrally formed with the clip body and the lid body, and has lock means capable of locking the clip body and the lid body in the locked state in which the clip body and the lid body are closed. Achieved by

According to the above structure, the wire holding portion for bending and holding the wires of the wire group and the tube fixing portion for fitting and holding the corrugated tube are connected to each other via the hinge so as to be openable and closable. Since it is integrally formed with the lid, the corrugated wire group is inserted by a simple operation that puts the electric wire and the corrugated tube between them and locks the clip body and the open / close end of the lid. The tube can be positioned and fixed at a predetermined position on the wire group. Further, since the electric wire holding section bends and holds the electric wires of the electric wire group in a line in parallel, the electric wire holding portion can surely hold and fix the electric wire group regardless of the number of electric wires.

It is preferable that at least one of the clip body and the lid body should be fitted so that the tube fixing portion fits between the ridges formed continuously on the outer peripheral surface of the corrugated tube. An electric wire group is formed on the inner wall surface of each of the clip body and the lid body so that the electric wire holding portion holds the electric wire group in a meandering shape in a bent state. A plurality of electric wire holding ribs that are alternately provided along the longitudinal direction.

In this case, the fitting protrusion formed on the inner wall surface of at least one of the clip body and the lid body is provided between the ridges formed continuously on the outer peripheral surface of the corrugated tube. By fitting, the corrugated tube can be firmly fitted and sandwiched without causing positional displacement along the axial direction, and a plurality of electric wire holding ribs projectingly provided on the inner wall surfaces of the clip body and the lid body. However, since the wire group is surely clamped in a meandering shape in a bent state, the corrugated tube can be reliably positioned and fixed at a predetermined position on the wire group with a simple structure.

Preferably, an opening for avoiding interference with the outer peripheral surface of the end portion of the corrugated tube fitted and sandwiched by the tube fixing portion is provided in the clip body and the lid body and closed. The height dimension of the clip body and the lid body in the locked state is formed to be substantially equal to the outer diameter of the corrugated tube.

In this case, the height of the corrugated tube clip can be reduced by the thickness of each inner wall of the clip body and the lid, and the clip can be miniaturized. Further, since the position of the outer peripheral surface of the end portion of the corrugated tube fitted and sandwiched by the tube fixing portion can be visually confirmed from the opening, the end portion of the corrugated tube can be reliably fixed to a predetermined position of the tube fixing portion. .
