Description

The present invention relates to an optical fiber connection core storage unit,
In particular, the present invention relates to a connection point of an optical fiber core in an optical cable connection part and a protective storage structure for an extra length of the optical fiber core generated at the connection point.

[Conventional technology]

The purpose of the optical fiber connection is to maintain an optical fiber connection point and to store and protect the extra length of the optical fiber. For example, as shown in Japanese Utility Model Application Nos. 61-151022 and 63-09673, the conventional optical fiber connection core storage section is composed of various components for holding and protecting.

[Problems to be Solved by the Invention] Particularly in recent years, it has been simplified to cope with the expansion of future optical terminal equipment by introducing a multi-core optical cable and arranging an optical connector connection portion in an optical fiber connection box. This tends to be the case. Therefore, the optical fiber connection box using the conventional optical fiber connection core storage unit has a drawback that the size is increased by increasing the number of optical fiber cores and mounting the optical connector connection portion.

[Means for solving the problem]

The optical fiber connection core storage unit of the present invention is supported by the storage unit main body made of a material having flexibility and transparency, and a plurality of storage unit main bodies fixed near the center of the panel surface of the optical fiber connection box. A plurality of optical fiber holding bags for protecting the optical fiber connection point and the optical fiber core in a substantially bag shape, a holding plate for holding the holding bag against the storage unit body, and the storage unit A mechanism that can incline the gripping bag forming a part of the main body and supporting the gripping bag toward the front side when necessary.

Further, the present invention includes a gripping bag receiving portion for preventing lateral displacement of the plurality of gripping bags provided and supported on the storage unit main body.

Furthermore, in the present invention, the gripping bag is made of a thin resin plate and can be bent freely.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing a mounted state of one embodiment of the present invention,
FIG. 2 is a perspective view of the present embodiment, and FIG. 3 is a perspective view showing a gripping bag of the present embodiment.

In this embodiment, an optical fiber connection core wire storage unit main body (hereinafter, storage unit main body) 2 fixed by a fixing screw 4 to approximately the center of an in-panel fixing plate 3 of a panel box 1 serving as an optical fiber connection box. A plurality of optical fiber line gripping bags (hereinafter, gripping bags) 8 made of a thin resin plate which are formed in a bag shape and are supported by the storage unit main body 2 and protect the optical fiber connection points and the excess length of the optical fiber core; A holding plate 9 for holding the gripping bag 8 against the storage unit body 2;
And a mechanism for tilting the gripping bag 8 to the front side by removing the holding screws 10 on both sides, and a gripping bag receiving portion 11 which also serves to prevent lateral movement and support of the gripping bag 8. .

That is, as shown in FIG. 1, the storage unit main body 2 is fixed to the fixed plate 3 in the plate by the fixing screw 4. The optical cable 6 is introduced from the cable introduction port 7 of the panel box 1, and the sheath is removed near the introduction port to become the optical fiber core wire 5, and enters and exits from the openings on both sides of the storage unit main body 2. Second
As shown in the drawing, the storage unit main body 2 has a structure in which a plurality of gripping bags 8 accommodating the optical fiber core wire 5 and the protective sleeve 12 and a gripping bag holding plate 9 are accommodated in a gripping bag receiving portion 11, Both sides 2 holding the unit body 2 horizontally
When the holding screw 10 of the book is removed, the gripping bag 8 is inclined in the direction of the arrow.

FIG. 3 shows the gripping bag 8 processed by a thin resin plate,
This shows a state in which this is bent and the protective sleeve 12 for protecting the connection point of the optical fiber cores 5 and the extra length of the optical fiber core 5 are gripped.

〔The invention's effect〕

As described above, the optical fiber connection core wire storage unit of the present invention can store a plurality of gripping bags in one unit, and thus has an effect of obtaining a high storage density. Further, the holding of the holding bag facilitates the separation of the optical fibers. In addition, since there is a mechanism to incline the gripping bag receiving part to the front side, even when adding optical terminal stations or switching lines, it is possible to easily pull out the gripping bag of the required core wire, significantly improving workability. Can be improved.
