Furthermore, in order to optically connect optical devices installed apart from each other, it is necessary to connect optical fibers drawn out from both of these devices. When connecting such optical fibers,
In order to easily assemble and maintain the device without damaging the optical fiber, the optical fiber at the connection section is usually made with an extra length, that is, a length with an extra length (extra length optical fiber). is set to Therefore, due to the characteristics of the optical fiber (to prevent deterioration of transmission characteristics, etc.), the extra length of the optical fiber at the connection part (extra connection length) should be in the form of a ring with a diameter of more than a predetermined value (for example, about 100 mm or more). It must be stored rolled up. In order to process and accommodate the extra connection length of the optical fiber in this manner, the accommodation device according to the present invention is used. In the case of the above-mentioned optical repeater, this accommodation device is usually arranged inside the repeater housing. When optical devices are connected to each other, a connector is placed between the two optical devices, and a housing device is provided within the connector. 1st

いた。(c) Prior art and problems A conventional optical fiber connection excess length storage device includes a disc-shaped base having an annular groove for accommodating the excess length, and a seal for closing the annular groove. It consists of a lid. When the extra length is rolled up and stored in the annular groove, tape or the like is temporarily attached to several places on the top surface of the annular groove to prevent the extra length that has already been rolled up from escaping during the accommodation process. Therefore, it was necessary to carry out work to accommodate the excess length. After the winding work is completed, the tape is removed and the sealing lid is fixed on the base. Therefore, with this conventional storage device, there are problems in that the work of storing the extra length is very complicated and time-consuming, and also, as mentioned above, when the sealing lid is finally fixed, it is necessary to remove the temporary tape. There is a problem in that a part of the extra length part escapes from the annular groove and is easily damaged by being caught between the sealing lid and the base. In addition, since this kind of optical fiber connection work and work to accommodate the excess length is mostly done at the installation site of the optical equipment, it is not recommended to use large-scale or expensive jigs. Although it is difficult in practice, the above-mentioned problems are particularly important, and their solution has become a major issue.

The housing device 30 of this embodiment basically includes a base 31, a restraint member 32, which is a feature of the present invention, and a sealing lid 33. The base 31 is formed into a disk shape from a thick plate material (metal material, resin material, etc.), and has an annular groove 31a formed along its outer periphery and a restraining member formed on the upper surface of the annular groove 31a. 32 fitting grooves 31b (in this case, four equally spaced locations on the circumference) and a connecting part 34 fitting groove 31c of the extra length of the optical fiber formed near the restraining member 32 fitting groove 31 are provided. An insertion hole 31d is bored in the portion. And the base 31
is fixed to an end wall (or side wall) 38 or the like of an optical device (for example, the repeater main body 15 of the optical repeater 10 in FIG. 1) via a support member 37. The restraint member 32 is formed into a rectangular shape from a plate-shaped elastic material such as a rubber plate, an elastic resin plate, etc., and is installed in each fitting groove 31b so as to span over the upper surface of the annular groove 31a. , one end (in this case, the inner end) is fixed onto the base 31 with a screw 35. As a result, the other end (outer end in this case) of the restraint member 32 is attached so as to be freely openable as shown in FIG. The depth of the restraint member fitting groove 31b is as follows:
When the restraint member 32 is attached, the upper surface of the member 32 is on the upper surface 3 of the base 31 on the outside of the annular groove 31a.
1e (see FIG. 3). Note that the restraining member 32 is not limited to the rectangular planar shape as described above, but may be formed in other shapes, and is not limited to the plate material as described above, but may be formed into a prismatic shape as necessary. It may be formed from a material such as wood or a cylindrical material. The sealing lid 33 is made of a plate material (metal material,
A ring-shaped hollow disc is formed from a resin-based material, etc.), and a ring-shaped stepped protrusion 33a is provided along the outer periphery of the lower surface of the disc. 32 is fixed on the base 31 with the upper surface closed by screws 36. The accommodation device 30 of this embodiment is configured as described above, and includes the optical fiber extra length portions 18b, 40.
The housing and connection of b are carried out as follows.
The sealing lid 33 is installed prior to the first housing and connection work.
