[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage rack for storing optical communication equipment, and more particularly to a storage rack for optical communication equipment having a function of processing an extra length of an optical cable.

[0002]

2. Description of the Related Art Recently, optical communication devices using optical cables have been miniaturized, and a plurality of optical communication devices have been housed in a storage rack. 2. Description of the Related Art A storage rack for an optical communication device for processing extra length of an optical cable has been developed. FIG. 7 shows such a storage rack for optical communication equipment, and reference numeral 1 denotes a storage rack main body.

A cable processing section 1a is formed in the upper part of the storage frame main body 1, and an optical cable extra length processing tool 3 is arranged in the cable processing section 1a. As shown in FIG. 8, the optical cable extra length processing tool 3 has a plate shape, and has four protrusions 3a, 3b, 3c, and 3d that protrude from the center in four directions on the same plane. It is formed in a character shape.

A mounting portion 3e is formed at the tip of the projecting portion 3a, and a mounting hole 3f for locking to the storage frame main body 1 is formed in the mounting portion 3e. In addition, the protrusions 3b,
Contact portions 3g, 3h, 3j for mounting the optical cable extra length processing tool 3 on the storage frame main body 1 are formed at the distal ends of 3c, 3d. Further, the projections 3a, 3b, 3c, 3d
A resin cable clip 5 is arranged on the upper surface of the optical cable at a predetermined distance from the center of the optical cable extra length processing tool 3.

As shown in FIG. 7, a screw member 7 is inserted into a mounting hole 3f of the mounting portion 3e, and the optical cable extra length processing tool 3 is fixed to the cable processing portion 1a. Further, a power cable 9 is provided on the back side of the cable processing section 1a.
The power supply unit 11 to which is connected is arranged. In addition, an opening 1 for introducing a cable is provided on a side wall of the cable processing section 1a.
b is formed.

Further, below the cable processing section 1a,
A storage section 1c is formed, and a plurality of printed wiring boards 13 having an optical communication function are stored upright in the storage section 1c. Then, a plurality of optical cables 15 of a predetermined length are introduced into the cable processing section 1a from the opening 1c.

The extra length 15 of the introduced optical cable 15
a is bundled in an annular shape and fixed to the cable clip 5 of the optical cable extra length processing tool 3. Then, the tip of the optical cable 15 is introduced into the storage section 1 c and connected to the printed wiring board 13.

[0008]

However, in such a conventional storage rack for optical communication equipment, the structure of the optical cable extra-length processing tool 3 is complicated and large, and the optical cable extra-length processing tool 3 is used for cable processing. Since a large number of optical cables 15 cannot be arranged in the portion 1a, the extra length processing of the plurality of optical cables 15 must be performed by one optical cable extra length processing tool 3, and a bulging portion 15b is formed in the extra length portion 15a. Therefore, it is not easy to maintain the optical cable 15 at a predetermined radius of curvature, and there has been a problem that a large number of work steps are required for the extra length processing.

When the line is switched or cut off, the optical cable 15 bundled in the optical cable extra length processing tool 3 is
Therefore, there is a problem that it is difficult to easily attach and detach only the predetermined optical cable 15. Furthermore, when a tool or the like touches the bulging portion 15b of the adjacent optical cable 15 at the time of the extra length processing, the extra length shape of the bulging portion 15b may change and bending loss may occur, and the optical cable 15 itself may be damaged. There was a risk of doing so.

Then, there is a problem that it is difficult to attach and detach the power cable 9 to and from the power supply section 11 with the optical cable extra length processing tool 3 attached to the cable processing section 1a. SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an optical communication system capable of easily processing an extra length of an optical cable introduced into a storage rack and holding the optical cable in an orderly manner.
