Description

[Detailed Description of the Invention] The present invention relates to an optical communication terminal board housing device used in optical communication equipment.

In conventional storage devices, the optical fiber connection to the optical connector on the terminal board is vertical.
Furthermore, since the intra-office optical fiber cable is wired on both left and right sides of the housing, the area occupied in the width direction of the device increases. However, since the wiring of the small capacity and large capacity lines is performed using equipment of the same configuration, in a station building where only the small capacity line is required, the implementation efficiency is poor due to the space inside the box and the station building, leading to an increase in cost. Further, when wiring to the terminal board, there is a drawback that the extra length processing plates attached to the upper and lower spaces get in the way, making it difficult to wire.

SUMMARY OF THE INVENTION An object of the present invention is to provide a terminal board storage device that eliminates the above-mentioned drawbacks.

The terminal board storage device of the present invention is composed of an optical terminal board block that accommodates a plurality of optical fiber cables and connects the optical fibers, and a frame housing to which the optical terminal board block is fixed. The frame housing has a plurality of optical sockets arranged in one direction and a plurality of first optical fiber cable winding saddles arranged on both sides in the same direction as the optical sockets and holding the optical fibers. a terminal board mounted vertically on the back surface of the terminal board, and a plurality of second fiber optic cable winding saddles arranged in the same direction as the optical socket on each surface facing each side of the terminal board, respectively. Two side plates are provided with a plurality of cable rings for guiding the fibers, and a plurality of third cable rings arranged in the same direction as the optical socket are attached to the surface fixed to the terminal board etc. on the back of the chassis. a back plate having a fiber optic cable winding saddle, and the first, second and third fiber optic cable winding saddles are arranged in an annular shape.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 and FIG. 2 are a front view and a sectional view, respectively, showing a conventional terminal board storage device.

In the figure, reference numeral 101 indicates the housing, and the same numeral 1
02 is the extra length processing plate of the optical fiber 103 to which the winding saddle 107 is attached, and the same number 110
is a terminal board to which an optical connector 111 is attached and is mounted horizontally to the housing.

Figure 3 is a perspective view showing one embodiment of the present invention;
The figure is an enlarged perspective view of the optical terminal board block of this embodiment, and FIG. 5 is a cross-sectional view of this embodiment.

In this embodiment, a cable wiring area having an optical fiber cable straightening member 2 is arranged on the back side of the housing 1.

Optical terminal board block 4 for such a housing 1
Installation work and optical fiber cable introduction work will be carried out as follows. An optical socket 11 provided so that the optical fiber 3 can be connected from the left and right horizontal directions, a winding saddle 7 for the optical fiber cable 3 provided on both sides of the back side of the housing, and a wire alignment ring provided on the upper side. 12 is fixed at the center of the housing 1 in the width direction.

Next, left and right side plates 5 and 6, to which the line alignment link 9 is attached to the front part and the winding saddle 7 is attached to the rear part, are fixed to both sides of the housing 1. Further, the back plates 8 and 8' to which the winding saddle 7 is attached are fixed to the back of the casing on both sides of the terminal board 10. Then, a protective cover 13 is attached to the front portions of the left and right plates 5 and 6.

For wiring to the optical terminal board block 4 configured as described above, first, the optical fiber cable 3 is introduced into the housing 1, passed through the straightening member 2 to straighten the fibers, and then Pull into block 4. The drawn-in optical fibers are processed to an appropriate length through the winding saddles 7 of each plate 5, 6, 8, and 8', and are connected to the optical sockets 11 of the terminal board 10 to be connected from both the left and right sides. Ru.

Next, connections within the same terminal board 10 made via the patch cord 14 are made using the left and right plates 5 and 6.
This is done through a straightening ring 9 attached to the front part of the wire. In addition, for connection to the adjacent terminal board storage device, the optical fiber cable 15 is introduced through the notches of the plates 5 and 6, and the excess length is processed by the plates 5, 6, 8, and 8' via the wire straightening ring 12. , is connected to the optical socket 11 of the optical terminal board 10.

In this way, the rear side of the storage case is used as the optical fiber cable area, and optical connections can be made in the left and right horizontal directions, making it possible to reduce the width and depth of the storage case, reducing the area occupied in the station building. be able to. Furthermore, since the terminal boards are housed in blocks, it is possible to economically construct both small and large capacity lines. Furthermore, all installation and connection work of the optical fiber cable to the terminal board can be done from the front of the housing, and since there is a large space, it can be easily done.

As described above, the present invention has the advantage that it can be economically implemented from small capacity lines to large capacity lines and can reduce the installation space of the apparatus.
