Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides an optical fiber at a connection point between a multi-core optical fiber, which is a collection of a plurality of optical fibers, and an individual optical fiber. Multi-core wire for branching and gathering core wires
Single-core conversion optical connector (hereinafter referred to as optical conversion connector)
This relates to a storage body.

(Prior art) Conventionally, this type of multi-fiber/single-fiber conversion optical connector (patent application 1986)
-8618 optical conversion connector, 1986-118985
The housing for the multi-fiber connector for optical branching had a structure as shown in FIG. That is, for example, a multi-core optical fiber core 4, which is a tape-like collection of five-core optical fibers, is separated into individual fibers through the multi-core plug 2 and the optical conversion connector main body 1, and is connected to a single-core plug with three ratios. has been done. The storage body shown in FIG. 8 stores these items at high density, and the optical conversion connectors 1 are arranged and stacked in such a way that the single-fiber wire plugs 3, which are frequently connected and disconnected, stand upright on the front, and are assembled into a unit. The mounting was done by fixing to the receptacle frame 7 via the panel 6.

As for the depth space of this storage structure, the multi-core plug 2
Width 68III+ of the optical conversion connector body l from to the side of the single-fiber wire plug 3, and length 30 mm of the single-fiber wire plug 3,

mm, and the total depth is 1281. On the other hand, structured wiring cabinets embedded in building walls and cabinets on telephone poles are intended for use with metallic core cables, and their depth is 120 mm, except for some large cabinets.
mm + or less (for example, as instructed in the "Telephone Piping Equipment Guidebook for Architectural Designers and Constructors" published by Hatsuoka, the Telephone and Telecommunications Public Corporation), so this optical conversion connector can be stored in most cabinets. This limited the application of economical multi-core cables in terms of material and construction costs, and it was necessary to use single-core cables for wiring.

In addition, since there was almost no gap between the single-core wire plugs, it was necessary to use a special tool to attach and detach them.

(Problems to be Solved by the Invention) An object of the present invention is to provide an optical conversion connector storage body that can be stored in a shallow storage space and has improved storage density and storage workability.

(Means for Solving the Problems) The first aspect of the present invention is to stack the optical conversion connectors at an angle, and to stack the optical conversion connectors on the opposite side of the single-fiber plug arrangement surface of the optical conversion connectors in the stacking direction of the optical conversion connectors. The optical conversion connector is assembled by providing a plurality of drilled through holes and passing a plurality of shafts through the through hole. It can be rotated and tilted.

The conventional structure is that the optical conversion connectors are stacked and stacked at an angle, and the optical conversion connectors are movable in a direction perpendicular to the side surface of the optical conversion connector body, making it possible to store the optical conversion connectors in a shallow storage space. The difference is that it is possible to do this, and at the same time, it is possible to secure work space for attaching and detaching the single-core wire plug.

The second aspect of the present invention provides a convex portion that can fix the optical conversion connector by tilting the optical conversion connector to assemble the product N and inserting it into a recess of the optical conversion connector, and a single-fiber wire connected to the optical conversion connector. The holder includes a plurality of holders each having a flat plate supporting the holder, and a plurality of shafts, and the holder is provided with a plurality of elongated through holes, and the plurality of shafts are passed through the through holes to achieve light conversion. The connector can be rotated and tilted in only one direction.

The conventional structure is that by stacking the optical conversion connectors at an angle, it is possible to store the optical conversion connectors in a shallow storage space. The difference is that it is possible to take out any intermediate optical conversion connector while the optical conversion connector remains connected, and that single-fiber wires can be stored in an orderly manner.

(Example) Fig. 1 is a perspective view of an optical conversion connector storage body of the present invention, where l is the optical conversion connector main body, 2 is a multi-core plug, 3 is a single-core plug, and 4 is a multi-core optical fiber core. 5 is a single optical fiber core, 6 is a panel for mounting the unit, 7 is a receptacle rack, and 8 is a single fiber receptacle.

The optical conversion connectors are arranged in a stacked manner with the single-fiber receptacles 8 tilted toward the front, and in this state, the units are fixed to the receptacle rack 7 via the panel 6. With this structure, as shown in Figure 2, as the inclination angle θ of the optical conversion connector increases beyond 10 degrees, its depth decreases until the inclination angle θ becomes 20 degrees. If it exceeds D, it can be stored within a space within D < 120mm.

Furthermore, as shown in FIG. 3, an introduction cable 9 and a tension member 10 are installed inside the cabinet.
It is fixed by a cable jacket fixing part 13 and a tension member fixing part 14 attached to the back plate 12 of No. 1. In order to effectively utilize the internal volume inside the cabinet, the introduction cable 9 is placed at the back of the cabinet 11 near the back plate 12, and the optical conversion connector is placed at an angle in the space in front. The storage space 15 inside the cabinet is made more efficient.

FIG. 4 is a perspective view showing the first embodiment of the present invention,
In the drawings, the same components as those shown in FIGS. 1 and 3 are denoted by the same reference numerals. The optical conversion connectors are stacked while being supported by two shafts 18 passed through two through holes 17 on the back surface 16, and have a structure that allows them to be moved up and down individually. Normally, the optical conversion connector is stored at an angle as shown in state a, and when connecting/removing the single-fiber plug, keep the optical conversion connector in a horizontal position so that the plug can be easily inserted/removed. Further, lift it up as shown in state C and work angle φ
Do this while ensuring that. Further, the optical conversion connector is attached to the shaft through the cut 19 of the shaft. By adopting such a structure, a wide working space is secured for attaching and detaching the optical conversion connector and the single-core wire plug, and manual work is possible without using a special tool.

Figure 5 is a perspective view of the second embodiment of the present invention, in which 40 optical conversion connectors for 5-fiber tape fibers are installed in a cabinet with a height of 480 mm, a width of 425 mm, and a depth of 120 mm. This shows an optical conversion connector storage body that accommodates a total of 200 fibers. In the figure, the same components as those shown in FIGS. 1 and 3 are denoted by the same reference numerals.

6 and 7 are perspective views showing the structure of the optical conversion connector holding holder 20 that secures the optical conversion connector, and FIG. 6 is a flat plate of metal such as aluminum that is cut and folded, and FIG. is made of plastic, and includes a fixing protrusion 21 that positions and holds the optical conversion connector by inserting it into a pre-prepared hole in the optical conversion connector body, and a rounded single-fiber wire connected to the optical conversion connector on the holder. The fiber tray 22 for holding the connecting fibers and the fiber guides 23 and 23' for stably holding the connecting fibers are provided. With this structure, any intermediate optical conversion connector can be taken out while the plugs of other optical conversion connectors remain connected, and the single-fiber wires can be stored in an orderly manner.

Although the embodiment has been described above in which the optical conversion connectors are vertically stacked with the optical conversion connectors tilted downward, the optical conversion connectors can also be configured by stacking the optical conversion connectors horizontally.

(Effects of the Invention) As explained above, the present invention makes it possible to store the optical conversion connector in a shallow storage space of 120 cm or less by tilting the optical conversion connector. A large working space is secured for attaching and detaching the parts, and manual work is possible without using special tools.
