DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness mounting structure that can be easily attached to and detached from a lean hose in an instrument panel (abbreviation of an instrument panel) and that a good mounting state can be obtained.

[0002]

2. Description of the Related Art A wire harness (a bundle of a plurality of lead wires) routed to an instrument panel is attached to a lean hose in the instrument panel. Conventionally, as shown in FIG. 5, the elastic locking piece 11 is wrapped around the wire harness 1 with an adhesive tape 10 and fixed (FIG. 5A), and the tip of the elastic locking piece 11 is attached to the lean hose 3 as shown in FIG. The tongue piece 12 of the elastic locking piece 11 is pressed against the stop hole 7 so that the tongue piece 12 of the elastic locking piece 11 passes through the stop hole 7.
(See FIG. 5B).

[0003]

However, in order to remove the wire harness from the lean hose, the wire harness 1 is forcibly pulled upward in FIG. However, in a narrow place such as in a car, there is no space for forcibly pulling the wire harness 1, and there is a case where the removal work is difficult. In that case, the tip of a flathead screwdriver was inserted between the elastic locking piece 11 and the lean hose 3, and the elastic locking piece 11 was forcibly removed from the stop hole 7 by prying. However, this operation was extremely difficult, because it was not always possible to remove it. Improvement of the work of removing the wire harness has been strongly demanded in recent years, while the importance of recycling automobiles and OA equipment has been emphasized. Other than the problem of removal, there is a problem related to the mounting state in which the wire harness rotates around the stop hole 7 after mounting and interferes with other components. The present invention
It is an object of the present invention to provide a wiring harness mounting structure that can be easily attached to and detached from a lean hose in an instrument panel, and that provides a good mounting state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the mounting structure of the present invention, for example, a clamp is previously held at a predetermined position of a wire harness, and an openable / closable elastic holding portion of the clamp is provided on an inner surface of the elastic holding portion. In a state where the projection is positioned so as to coincide with the stop hole formed in the lean hose, the elastic holding portion can be obtained by spreading both ends of the elastic holding portion and covering the lean hose. Also, removal can be easily performed by pulling the clamp away from the lean hose. In the present invention, the rotation of the wire harness in the circumferential direction or the longitudinal movement of the wire harness with respect to the lean hose is prevented by locking the protrusion on the inner surface of the elastic grip portion into the stop hole of the lean hose.

In the present invention, the elastic holding portion for holding the lean hose is made of an elastic synthetic resin or metal material. The grip portion for gripping the wire harness is formed by a surrounding band or the like. The surrounding band and the like may be removed after removing the clamp holding the wire harness from the lean hose. If the wire harness holding portion is also an elastic holding portion that can be opened and closed, the attachment and detachment of the wire harness can be performed more easily.

Hereinafter, the present invention will be specifically described with reference to the drawings. FIG. 1A is a perspective view showing a first embodiment of the mounting structure of the present invention, and FIG. 1B is a cross-sectional view of a main part of the mounting structure. Reference numeral 1 denotes a wire harness in which a plurality of electric wires are bundled. 3
Is, for example, a lean hose provided in an instrument panel of a vehicle. Reference numeral 5 denotes a clamp made of a synthetic resin (polypropylene, nylon, polybutylene terephthalate, etc.), a band-shaped grip portion 2 for bundling and gripping the wire harness 1, and a substantially U-shaped elastic grip for elastically gripping the lean hose 5. The part 4 is formed integrally. The above U
At the bottom of the U-shaped elastic holding part 4, it projects toward the opening,
A projection 6 is provided to be locked in a stop hole 7 formed in the lean hose 3.

According to the mounting structure of the present invention, the elastic holding portion 4 of the clamp 5 for holding the lean hose 3 has an open end so that it can be opened and closed. Since the protrusion 6 provided on the inner surface of the elastic holding portion 4 is stopped by being locked in the stop hole 7 formed in the lean hose 3, the wire harness 1 is prevented from moving in the length direction.
Can be easily attached to and detached from the lean hose 3. Further, since the wire harness 1 and the lean hose 3 are gripped by the single clamp 5, the wire harness 1 bundled and gripped by the grip portion 2 does not rotate with respect to the lean hose 3. In the present invention, the shape of the protrusion 6 on the inner surface of the elastic holding portion is arbitrary, such as a conical shape or a cubic shape.

FIG. 2 is a cross-sectional view of a main part showing a second embodiment of the mounting structure of the present invention. In this mounting structure, the protrusions 6 are formed at three places at the center and both ends of the inner surface of the elastic holding portion 4, so that the clamp 5 can be satisfactorily held by the lean hose 3.

FIG. 3 is a cross-sectional view of a principal part showing a third embodiment of the mounting structure of the present invention. As shown in FIG. 3, the elastic holding portion 4 may be provided by forming a cylindrical shape with overlapping end portions. In this mounting structure, since the ends of the elastic gripping portions 4 are overlapped, the clamp 5
It is better gripped.

FIG. 4 is a cross-sectional view of a main part showing a fourth embodiment of the mounting structure of the present invention. In this mounting structure, the wire harness grip 2 is provided inside the elastic grip 4.
A wire harness 9 formed in a flat shape is provided on the grip portion 2.
Is gripped. The protrusion 6 on the inner surface of the elastic holding portion 4 is provided at one place, and the ends of the elastic holding portion 4 overlap.

The elastic grip 4 may be made of a plate-like metal material, and the clamp 5 may be provided integrally with the band-like grip 2 made of synthetic resin.

[0013]

As described above, in the present invention, the elastic holding portion of the clamp for holding the lean hose is elastically provided, and the rotation of the wire harness in the circumferential direction and the movement in the length direction with respect to the lean hose are controlled. Since the projection provided on the inner surface of the elastic grip portion is locked and stopped by the stop hole formed in the lean hose, the wire harness can be easily attached to and detached from the lean hose even in a narrow space. Further, since the clamp grips the lean hose by the elastic gripping portion, the wire harness does not rotate around the stop hole of the lean hose after installation and does not interfere with other components. Therefore, an industrially remarkable effect is achieved.
