DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable extra storage box used for laying and installing a communication cable having connectors at both ends.

[0002]

2. Description of the Related Art In recent years, the elimination of work in laying and connecting a communication cable has been studied in various fields. In particular, cable connection work often takes a long time, and if there are many core wires, the work may take several days. In addition, in the case of an overhead line, the weather deteriorates, the construction is prolonged, and the construction cost rises, as well as adverse effects on society, such as the extension of road regulations during the construction period.

[0003] In order to eliminate the adverse effects of the prolonged construction, a construction method for simplifying the connection construction has been actively adopted. As an example of the construction method, connectors are attached to both ends of the cable in advance,
There is a method of using a so-called communication cable with a connector at both ends, which enables completion of the time required for core wire connection at the site in a short time.

[0004] Incidentally, in the above-mentioned communication cable with connectors at both ends, unless the length of the line to be laid is strictly measured,
This was apt to lead to a situation where the cable was too short to be connected, or a situation where the cable was too long to handle excess cable. However, as a practical matter,
Most of the overhead lines have many curves, etc.
It is extremely difficult to accurately measure the line length. Therefore, in practice, a method has been adopted in which the cable is laid using a communication cable with a connector at both ends longer than the line length, and a surplus cable is wound up in the middle of the route.

FIG. 5 shows a conventional means for storing the excess cable length described above. That is, an arm 4 for suspending the support wire 2 of the cable 1 is fixed to the utility pole 3, and a U-shaped metal fitting 5 that can secure an allowable bending diameter of the cable is attached to the tip of the arm 4, The extra length portion is wound in a ring shape with the U-shaped fitting 5 attached, and the spiral sleeve 7 for trauma prevention is wound around the extra length portion. 8, the bracket is fixed to the U-shaped bracket 5 and the support wire 2 by being respectively tied.

Other conventional means for storing the extra cable length other than those described above are shown in FIGS. This is achieved by suspending a box 9 having an open front with respect to the arm 4 fixed to the utility pole 3, and attaching the bundled cable extra length to a rectangular guide 9a housed in the box 9. 6 is stored.

[0007]

In the case of the means shown in FIG. 5, the extra length of the cable is exposed, so that the extra length is damaged at the time of other cable laying work. Not only was there a danger, but the appearance was extremely unsightly in such an exposed state. Furthermore, since the curvature of the U-shaped fitting 5 is fixed in the work, there is a problem that it is extremely difficult to take the full length so as to exactly fit the U-shaped fitting 5. I was forced to do that.

In the case of the means shown in FIGS. 6 to 8 described above, the work of storing the bundled cable extra length 6 in the rectangular guide 9a involves not only a complicated and difficult work but also a box. Since the body 9 was closed at the back but opened at the front, it became bag-like and the wind pressure load was significantly increased, which could adversely affect the extra cable length.

The present invention solves the above-mentioned disadvantages of the prior art, remarkably improves the storage capacity of the cable extra length, prevents damage to the cable, and uses the cable without being affected by wind pressure load even in a strong wind area. The present invention provides a new cable extra-length storage box in which is made possible.

[0011]

1 to 3 show one embodiment of the present invention. In FIG. 1, reference numeral 10 denotes a storage box for storing an extra length of a cable, which is configured as follows.

Reference numeral 10a denotes a substrate of a storage box, and a cable extra-length winding cylinder 10b is attached to a central portion of the front surface thereof. The cylindrical body 10b has a diameter equal to or larger than the allowable bending diameter of the cable to be wound, penetrates the substrate 10a, and is connected to a bottom plate via a flange provided at the rear end of the cylindrical body 10b. It is configured to be fixed to 10a.

Reference numeral 10c denotes a cable fixing metal provided on the substrate 10a, and 10d denotes a hanging metal. The cable fixing brackets 10c are provided at the four corners of the substrate 10a, and are provided with cable fixing holes 10e in the vertical and horizontal directions, respectively, so that the cable 1 can be introduced in any of the vertical and horizontal directions as shown in FIG. It is.

Reference numeral 10f denotes a lid of the storage box, and a fitting opening 10h for opening the tip of the above-mentioned extra-length cable winding tubular body 10b is formed in the center thereof. That is, when the substrate 10a and the lid 10f are aligned with each other as shown in FIG. 2, the leading edge of the cylindrical body 10b is fitted into the fitting opening 10h, and the substrate 10a and the lid 10f are aligned. Is configured to be stabilized.

Reference numeral 10g denotes a cable inlet, which is provided so as to correspond to the cable fixing bracket 10c on the side of the substrate 10a, and is configured so that the cable 1 is guided into the storage box 10 in any of vertical and horizontal directions. is there. Reference numeral 10k denotes a flange portion connected to the peripheral portion of the lid 10f, which is screwed to the substrate 10a to connect them, as shown in FIG.

Numeral 10j denotes ventilation small holes formed on the surfaces of the substrate 10a and the lid 10f to reduce the wind pressure load when the storage box 10 is installed by improving the ventilation. This is for planning. It should be noted that the above-mentioned tube opening of the extra-length cable winding tube 10b has a similar effect.

When the present invention is used, the lid 10f is removed as shown in FIG. 1 and the extra cable length 6 is "circled in eight" as shown in FIG. At the same time, it is fitted around the outer periphery of the winding cylinder 10b. After that, lid 10
When f is attached, the accommodation of the extra cable length 6 is completed.
The box 10 is fixed to the cable 1 by a cable fixing bracket 10c.

FIG. 4 shows another embodiment of the present invention, in which the lower part of the storage box 10 is formed in an arc shape so as to minimize the dead space of the storage box. It was made. Also, in the one shown in FIG.
In some cases, a detachable or slidable partition is provided, and after the cable extra length 6 is stored as described above, the partition can be fixed so as not to move by the partition.

[0019]

According to the present invention, since the storage box for storing the extra cable length is formed by the substrate 10a and the lid 10f, the extra cable length portion is put in the storage box 10. Thus, prevention of the damage and improvement of appearance are achieved. At the same time, since the extra cable length is not exposed as described above, there is no need to worry about snowing on the cable,
Therefore, application to heavy snowfall areas is also possible.

According to the present invention, a cable extra-length winding cylinder 10b having a diameter equal to or larger than the allowable bending diameter of the cable to be wound is provided at the center of the front surface of the substrate 10a.
