Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an optical connector equipped with an optical connector used in an optical fiber distribution board for terminating optical fiber cables and jumpering optical fiber cables. Regarding terminal boards.

[Conventional technology]

Conventional 1. The optical connector terminal board of this carpenter has a structure in which a plurality of optical connector adapters are arranged on the side surface of an L-shaped mounting plate, and an optical connector to which an optical fiber cord is connected is inserted into the optical connector adapter. Furthermore, the extra length of the optical fiber cord is bent and accommodated at the bottom of the mounting plate at random.

[Problem that the invention seeks to solve]

Therefore, in the conventional optical connector slave board described above, all the original fiber cords connected to the optical connectors inserted into each adapter are concentrated on the bottom surface of the mounting plate, and the optical 7-ip cords are congested and confounded. It had the disadvantage of inviting Additionally, approximately 50 to 100 optical connector adapters are usually mounted on the original connector cover terminal board in order to improve mounting efficiency. This has the disadvantage that it becomes impossible to distinguish the correspondence between the connector and the optical 7-eyeper. For this reason, when reaccommodating an optical connector from its current inserted position to another location, it has become a difficult task to find the optical fiber cord that corresponds to the optical connector.

[Means for solving problems]

The optical connector terminal board of the present invention is mounted in groups in vertical and horizontal rows on the side surface of an L-shaped mounting plate, and has nine optical connector adapters and the remaining length of the optical fiber cord is wound in correspondence with the optical connector adapters. an optical fiber cord extra-length geomechanism that is closely arranged on the bottom of the mounting plate so that the disc-shaped reel to be attached can freely rotate through the shaft; and a roughly trumpet-shaped optical fiber on both ends of the bottom of the mounting plate. It is characterized by comprising an optical fiber cord mounting member for ensuring a bending radius and for accommodating wire alignment.

Further, the optical connector terminal plate of the present invention is characterized in that it is provided with a lattice plate for separating the optical fiber cords, which is provided on the bottom surface of the mounting plate.

Optical connector adapters 2 are fixed in horizontal rows in a staggered manner by screws or the like (FIG. 1A). Additionally, on the bottom surface 1b of the mounting plate 1, there is provided a 4° extra length of the optical fiber cord connected to the optical connector 3 inserted into the adapter 2, corresponding to the optical connector adapter 2. A disc-shaped reel 5 is rotatably arranged in close contact with the rotating shaft 6 (FIGS. 1B and 1C). This disk-shaped reel 5 is configured to be able to wrap the extra length of the fiber cord 4 one to three times, and has a maximum extra length processing capacity of 50 centimeters. In addition, when reaccommodating the optical connector 3, the disc-shaped reel 5 is rotated to the front side (Y direction in FIG. 1C) via the shaft 6, and the optical connector inserted into the optical connector adapter 2 is rotated. After pulling out the cord 3, the cord 4 can be unwound by unwinding it in the opposite direction to the direction in which it was wound. Further, at both ends of the bottom surface 1b of the mounting plate 1, there are provided approximately horn-shaped optical fiber cord mounting members for securing the bending radius of the optical fiber cord and for accommodating and aligning the optical fibers.
