The second hole 216 is provided in 1d. A band is preferable as the fastening means. Cylindrical portion 211a, 2
After the extra length of the optical fiber cable 50 is wound around each of the optical fiber cables 11b, the fastening means is inserted through the first hole 215 and the second hole 216 and wound around the wound optical fiber cable 50. If the tightening means is tightened and fixed, the optical fiber cable 50 becomes the cylindrical portion 211a,
It is fixed around each of 211b. For this reason, it is not necessary to particularly perform the work of regulating the displacement of the optical fiber cable 50.

The fixing means 218 for fixing the interconnecting portion of the optical fiber cable 50 includes a cylindrical portion 211 of the side plate 212.
A pair is provided at the front part (upper part in FIG. 13) and the rear part between the parts a and 211b. The reason why a pair of fixing means 218 is provided is that the extra length of two optical fiber cables 50 is wound around one cylindrical portion 211a and two optical fibers are wound around the other cylindrical portion 211b. This is because the excess length of the cable 50 is wound, so that there are two interconnected portions of the optical fiber cable 50. The number of the fixing means 218 may correspond to the number of the interconnecting portions of the optical fiber cable 50, and may not be one pair. The interconnecting portion of the optical fiber cable 50 interconnects the optical connector attached to the end of the optical fiber cable 50 and the optical connector attached to the end of the optical fiber cable 50 wound around the cylindrical portion 211b. It consists of an adapter (not shown) to be connected. This adapter has a substantially cylindrical outer shape. For this reason, the fixing means 218 is provided as shown in FIG.
As shown in FIG.
and a pair of adapter grips 218b having a. When the adapter constituting the interconnecting portion is fixed by the fixing means 218, the adapter is fixed to the side plate 212, so that the adapter does not move in the housing case 210.

The cover 214 extends from the front end of the side plate 212 and covers the front of the cylindrical portions 211a and 211b, and the front cover 214a extends from the front end of the front cover 214a and has the other side plates 213a and 213b. And a side cover 214b that covers the side. By rotating the lid 214, the front of the cylindrical portions 211a and 211b and the sides of the side plates 213a and 213b are covered, but a first V-shaped groove is formed between the side plate 212 and the front lid 214a. The front lid 214a and the side lid 21
Since the second V-shaped groove 214f is provided between the cover 214 and the second cover 4b, the cover 214 can be easily rotated. The side lid 214b is provided with two reinforcing ribs 214c and 214d for reinforcing the side lid 214b along the front-rear direction. When the cover 214 is rotated, the side cover 214
b is located on the side of the side plates 213a and 213b, and the reinforcing ribs 214c and 214d are formed on the side walls 2 of the tubular portions 21a and 211b.
11c and 211d. At this time, the side wall 2
Since 11c and 211d are thinner than the side plates 213a and 213b, the side lids 214b do not rise from the side plates 213a and 213b due to the reinforcing ribs 214c and 214d. The front of the cylindrical portions 211 and 211b is covered by the cover 214, and the front of the optical fiber cable 50 wound therearound is covered.
0 is protected against foreign matter from the front.

The storage case 21 shown in FIGS.
0 are prepared in plural numbers, and the storage case 10 shown in FIGS.
As in the case of the first embodiment, it is housed in the case housing body 20 shown in FIGS.

For this reason, there is no need to perform an operation for regulating the displacement of the wound optical fiber cable. Further, since the cylindrical portion, the pair of side plates and the mounting means are integrally formed, the number of parts of the housing case is small, the structure is simple, and the manufacturing operation is easy. Further, since a cover extending from one side plate of the pair of side plates and covering a part of the periphery of the tubular portion is provided, one end of the optical fiber cable wound around the tubular portion is provided. The part is protected from the outside by the lid.

In the case container according to the present invention, a plurality of partition walls are provided on one or both of the bottom plate and the back plate to partition between the plurality of excess optical fiber cable storage cases. Since the pair of side plates are integrally formed by punching, bending, and welding, a case housing body having a simple structure and easy manufacturing operations can be obtained.

Further, the housing case assembly according to the present invention comprises a case housing for housing a plurality of optical fiber cables and an excess length housing case, and a case for preventing the housing case from dropping from the case housing. And a support bar, wherein the case housing mounts the plurality of extra length optical fiber housing cases and cuts and raises a plurality of first partition walls that partition between the excess length optical fiber housing cases. A formed bottom plate and a plurality of second partition walls formed by being bent from the rear end of the bottom plate and partitioning between the optical fiber cable extra-length portion storage cases in accordance with the first partition wall. The back plate, and a pair of side plates formed by being bent from the left and right ends of the back plate and having a bottom fixed to the bottom plate, and locking the case support bar. Small number of components, is easy the assembling work structure is simple.

Further, the optical fiber cable extra length housing case according to the present invention is provided with a fixing means for fixing an interconnecting portion of the optical fiber cable, which is provided on the side plate on which the lid extends, so that the optical fiber cable has an optical fiber cable. When the interconnecting portion of the fiber cable is fixed by the fixing means, the interconnecting portion is fixed to the side plate, so that the interconnecting portion does not fluctuate in the housing case. Also, since the pair of cylindrical portions, the pair of side plates, the lid, the mounting means and the fixing means are integrally formed, the number of parts of the housing case is small, the structure is simple, and the manufacturing operation is easy. .
