Abstract

PROBLEM TO BE SOLVED: To provide a escaped water preventing structure wherein working time is short and an installation place is unnecessary. SOLUTION: In an escaped water flowing outside tube preventing component, a notched part 3 is arranged on an annular member 2 which is made of resin and has a round hole 3 in the central part, and a relief part 4 made of resin is arranged in the vicinity of the notched part 3 in the outer peripheral direction. The escaped water flowing outside tube preventing component is attached and fixed on a cable 5. traveling on the cable 5 is brought into contact with the annular member 2 made of resin and flows and drops along the relief part 4 made of resin. In this escaped water flowing outside tube preventing structure, an occupied space for cable curing is unnecessary, and working process can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing running water from a cable in an outdoor communication device through which the cable penetrates and is introduced from the side.

[0001]

2. Description of the Related Art In a conventional running water structure, as shown in FIG. 7, in an outdoor communication device 8 into which a cable 5 is introduced from the side, the cable 5 is positioned lower than a bottom portion 15 of the outdoor communication device 8. After being bent to a position higher than the bottom surface, the cable is introduced into the outdoor-installed communication device 8, the lowermost portion 16 of the cable 5 is hung by the support 17, and the support is fixed to the fixture 19. I have.

In such a structure, the running water 6 transmitted through the cable 5 flows down to the lowermost portion 16 due to the curvature of the cable and falls.

[0003]

However, in the conventional structure, since the occupied space for the cable bending is required outside the communication device installed outdoors, a place where the occupied space for the cable bending cannot be secured (a large number of communication devices installed outdoors are required). In an artificially crowded area). In addition, the conventional running water prevention structure requires three steps of bending a cable, tying the cable to a support, and screwing the support to a fixture, which requires a great deal of time for construction. There is.

SUMMARY OF THE INVENTION An object of the present invention is to provide a running water prevention structure which eliminates the above-mentioned drawbacks of the prior art and improves the degree of freedom of installation by reducing the occupied space for cable bending and the workability by reducing bending work. It is in.

[0005]

In order to solve the above-mentioned problems, a running water prevention structure according to the present invention comprises a resin annular body having a round hole in the center, a cutout portion and a resin rod shape in the vicinity of the cutout portion. A running water prevention part with a relief part is attached and fixed to the cable.

In the above arrangement, after the notch on the resin annular body is pushed and spread, a round hole at the center of the resin annular body is attached and fixed to the cable in a direction in which the escape portion faces downward. Running water that has been transmitted through the cable due to rainfall or melting snow comes into contact with the resin ring and flows down along the resin protrusion.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a running water prevention component used in the present invention.

In FIG. 1, the running water preventing component comprises a resin annular body 2 having a round hole at the center and a resin-made bar-shaped escape portion 4 for allowing running water to escape. The annular body is provided with a cutout 3 for attachment to a cable.

FIG. 2 is a view showing a state in which a running water prevention component is mounted on a cable. In the figure, a resin annular body 2
After the upper cutout 3 is pushed open, a round hole at the center of the resin annular body is attached to the cable in a direction in which the resin bar-shaped relief portion 4 faces downward. It is desirable that the device be mounted on a position immediately near the outer surface of the outdoor communication device 8.

In such a configuration, the running water 6 transmitted through the cable 5 due to rainfall or melting snow comes into contact with the resin annular body 2 and flows down along the bar-shaped escape portion 4.

In place of the running water prevention component of FIG. 2, a cross-shaped component as shown in FIG. 3 can be used. In this case, since the escape portions are formed on all sides, there is no need to consider the direction of the escape portions as in the parts in FIG. FIG. 4 shows the mounted state.

Instead of the resin annular body 2 in the present invention, it is also possible to use a component having a resin conical portion 10 having a conical hollow portion as shown in FIG.

A notch is provided from the acute angle portion 11 of the resin conical portion to the end having the conical hollow portion. The plurality of resin protrusions 4 are mounted in the outer peripheral direction of the end 13.

As shown in FIG. 6, the acute angle portion 11 is cut so that a round hole 9 corresponding to the diameter of the cable 5 is formed, and the round hole 9 is attached to the cable and fixed to obtain a cable having various diameters. Can be applied.

[0015]

As described above, according to the present invention, an occupied space for cable bending for draining, which was conventionally required, is required, so that it can be installed in a place where the occupied space for cable bending cannot be secured. It has the effect of becoming. Also, in the present invention, a resin annular body is attached to a cable.
Since the work is completed in the process, the working time required for the running water prevention treatment is reduced to less than several seconds (about 1/20 as compared with the conventional structure), and the working efficiency is greatly improved.
