Abstract

PROBLEM TO BE SOLVED: To secure the water flow by suppressing any squeezing of a washer hose attached to a wire harness. SOLUTION: In a flexible washer hose consisting of resin or rubber which is arranged along the prescribed position of an outer circumferential surface of a wire harness and fitted to the wire harness by taping, projections 11-14 are provided on an inner circumferential surface with angular intervals of 90 deg. to secure a hollow part for passing water even when the hose is in a flat condition. Alternatively, the projections 11-14 are connected to each other to provide a cruciform partitioning frame so that the hose is difficult to flatten, and the water flow is secured thereby.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washer hose for attaching a wire harness. This is to ensure the distribution of water.

[0002]

2. Description of the Related Art In a motor vehicle, as shown in FIGS. 5A and 5B, a washer hose 1 is attached along the outer peripheral surface of a wire harness W / H, and the wire harness W / H is attached to the wire harness W / H with an adhesive tape 2. It is wound and fixed.

[0003]

The washer hose 1 is usually made of a transparent resin tube having an inner diameter of 4 mm and an outer diameter of 6 mm, and is easily flattened. Therefore, as shown in FIG. 6, the wire harness W / H
If the vehicle is bent sharply when it is mounted on the vehicle, the washer hose 1 may be flattened, the hollow portion may disappear, and the flow of water may be interrupted.

Further, as shown in FIG. 7, when a tape 2 for winding a washer hose 1 around a wire harness W / H is strongly wound, the washer hose 1 becomes flat, and the flow of water is cut off or extremely Flow becomes worse. Therefore, when the washer hose is wound around the wire harness and fixed, it is necessary to pay attention to how to wind the tape, and there is a problem that workability is deteriorated.

The present invention has been made in view of the above problems, and has been made in consideration of the problems described above.
It is an object of the present invention to make it possible to leave a hollow portion capable of securing the flow of water even when flattened.

[0006]

In order to solve the above-mentioned problems, according to the present invention, a resin or rubber is disposed along a required position on the outer peripheral surface of the wire harness and is attached to the wire harness by tape winding. A flexible washer hose, comprising: a projection provided on the inner peripheral surface at intervals of 90 degrees so that a hollow portion for water circulation can be secured even in a flat state. We provide washer hoses for attaching harnesses.

More specifically, the projections are provided facing each other with a gap therebetween, and the axial center portion is a hollow portion penetrating therethrough. When the projections are provided to face each other as described above, when the washer hose is flattened, the projections abut each other to prevent further flattening, and a hollow portion is secured in a direction orthogonal to the abutted projections. Therefore, water can flow through the hollow portion.

Alternatively, the projections are connected in a cross shape to partition into four hollow portions. As described above, when the protrusions are connected in a cross shape, the washer hose is less likely to be flattened, and even when flattened, a hollow portion for water circulation can be always secured.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a first embodiment of the present invention. A washer hose 10 attached to a wire harness W / H is made of a flexible resin and has an outer diameter of 6 m.
m, a long cylindrical shape with an inner diameter of 4 mm, and projections 11, 12, 1 having a height of 1 mm spaced 90 degrees from the inner peripheral surface thereof.
3, 14 are protruded.

The washer hose 10 is disposed at a required position on the outer peripheral surface of the wire harness W / H and is fixed by winding an adhesive tape 15 at intervals as in the prior art. At the time of winding with the adhesive tape 15, the washer hose 10 is flattened and wound so as not to be crushed.

However, as shown in FIG.
Even when the adhesive tape 15 is strongly wound and flattened, when the opposing projections 11 and 12 abut, the hollow portions 16 and 17 can be secured on both sides in the orthogonal direction. When the projections 13 and 14 come into contact with each other, similarly, hollow portions can be secured on both sides in the orthogonal direction.

Similarly, when the wire harness W / H provided with the washer hose 11 is routed to a vehicle and the vehicle is sharply bent and the washer hose 11 is flattened, similarly, as shown in FIG. , A hollow portion can be secured.

As described above, since the hollow portion can be secured even when the washer hose 11 is flattened, the flowing water is not blocked at the flattened portion, and the function of the washer hose 11 is not impaired.

FIGS. 4A and 4B show a second embodiment.
Inside the washer hose 20, the projections projecting at 90 ° intervals are connected to form a cross-shaped partition frame 21 protruding from the inner peripheral surface.
The two hollow portions 22, 23, 24, 25 are formed.

As described above, when the cross-shaped partition frame 21 is provided inside the washer hose 20, the shape is reinforced, and the washer hose 20 is hardly flattened.
Does not collapse easily. Also, even if the flat portion is flattened by a tape winding or a sharp load of the wire harness, as shown in FIG. 4B, the hollow portions 22 to 25 are deformed into an elongated shape as shown in FIG. The hollow portion is not completely closed, and the flow of water can be secured.

[0016]

As is apparent from the above description, the washer hose provided with the wire harness according to the present invention has:
Since the opposed projections or cross-shaped projections are provided inside, it is not easily flattened, and even if flattened, the hollow part is secured, so that the flow of water is not blocked, and the function of the washer hose Does not hurt.

Therefore, when winding a tape for attaching the washer hose to the wire harness, it is not necessary to pay close attention to the tape winding, so that workability can be improved. Also, when wiring the wiring harness to the vehicle, it is not necessary to consider the collapse of the washer hose, and the efficiency of the wiring harness wiring work can be improved.
