Description

[Detailed description of the invention] This invention is a storage plate for an optical fiber connection part, especially when storing the optical fiber connection part and the extra length core in a flat manner. The present invention relates to a storage plate for an optical fiber connection part that maintains a curvature of a certain level or more even when the length of the core wire changes, so that extra length core wires can be stored compactly.

Conventionally, in order to store an optical fiber connection part on a flat plate, as shown in FIG. The connected extra length core wire 5 was wrapped and stored. However, in this storage method, when the length of the extra-length fiber 5 changes, such as when the extra-length fiber 5 becomes shorter due to reconnection of the optical fiber 3, the extra-length fiber 5 is kept at a certain level. There were drawbacks such as the inability to maintain the curvature and store it.

In order to solve the drawbacks of the conventional storage board, the present invention stores the optical fiber connecting portion and the extra length of the fiber through several holders, and also creates a holder for storing the extra length of the fiber. By using at least one holder with a wider storage width than other holders, it is possible to have a degree of freedom in storing the extra length center line, and to maintain a curvature above a certain level to maintain the extra length center line. It is an object of the present invention to provide a storage plate for an optical fiber connection part that is configured so that wires can be stored compactly.

Hereinafter, the housing plate for the optical fiber connection part according to the present invention will be explained in detail with reference to FIGS. 2 and 3 (note that parts corresponding to the conventional example are given the same reference numerals and explained). .

In the present invention, a fiber connection part storage holder 6 is installed on the upper surface of the storage plate 1, and a storage width is provided to allow flexibility in storing the excess fiber length fiber storage holder 7 and the excess fiber length fibers 5. A flexible storage holder 8 with a wide extra length is installed. A plurality of extra length fiber storage holders 7 are installed, and at least one extra length fiber storage holder 8 is installed. That is, the fiber connection portion storage holder 6, the extra length fiber storage holder 7, and the extra length fiber storage holder 8 are comprised of a fiber storage portion 6a having a C-shaped cross section, as shown in FIG.
7a and 8a are formed, and the fiber accommodating portion 8a of the extra length fiber accommodating holder 8 is formed wider than the fiber accommodating portion 7a of the extra length fiber accommodating holder 7.

Therefore, in order to store the optical fiber core 3 in the storage plate 1 configured as described above, first, after the connection of the optical fibers is completed, the fiber connection part 4 is fixed to the fiber connection part storage holder 6. , the extra length fiber 5 is placed in the extra length fiber storage holder 7 and the extra length fiber storage holder 8
The optical fiber connecting portion 4 is housed by circulating the fiber between the two.

Here, the installation positions of the extra-length fiber storage holder 7 and the extra-length fiber flexible storage holder 8 are set at the minimum curvature specified so that the loss does not increase due to bending of the optical fiber when storing the extra-length fiber. Maintaining the same position and spacing. Therefore, if the storage plate 1 of the optical fiber connection part according to the present invention is used, even if the length of the extra core wire changes due to reconnection of optical fibers, the curvature above a certain level can be maintained and the structure can be made compact. can be stored in.

As described above in detail based on the embodiment shown in the drawings, the storage plate for the optical fiber connection part according to the present invention allows the fiber connection part and extra length fibers of the optical fiber connection part to be arranged in a plane. In the case of storing the extra length fibers in a storage space, a fiber connection part holder, an extra length fiber storage holder, and an extra length fiber flexible storage holder with a wide storage width are provided, and these are placed at a position that defines the minimum curvature for bending the extra length fibers. It has a simple structure in which the holder is placed on a storage plate, and even if the length of the extra core wire changes due to reconnection of the optical fiber, the curvature above a certain level is maintained for storing the excess core wire. It has practical effects such as being easy and compact to carry out.
