BACKGROUND OF THE INVENTION
The present invention relates to an optical cable connection box used for connection or branch wiring of an optical cable having an optical fiber core and a tension member. Specifically, each optical fiber cable such as an optical cable including a tension member is connected to a case main body, branched, and stopped. The present invention relates to an adapter device used in an optical cable connection storage cabinet such as a user premises cabinet that is held in a wearing state.
[0002]
[Prior art]
In general, when connecting an optical cable having an optical fiber core, branching / retracting connection of the optical fiber core includes an extra long core having a margin for the core in anticipation of connection failure and a core including a connection portion. A junction box is needed for wire protection. For this reason, conventionally, many storage trays are used to store the connection section and extra length after connecting the core wires, and the core wires are stored in the cabinet when the cables are branched and dropped out to various locations as floor cables. Arrangements or storage sheets are used.
[0003]
[Problems to be solved by the invention]
However, the conventional optical cable connection box requires a special wire connection processing member that uses a special case, cover, and sheet, has many assembly parts, is difficult to hold the cover, and handles any core wire. This is also a problem in terms of safety of wire connection and workability. The handling and arrangement structure of each core with multiple cores is complicated and the cost is high. There was a problem that it was difficult to store and the workability of cable connection was low.
The present invention is intended to eliminate these conventional drawbacks, and it is easy to handle the core wire within the case body, to replace and increase the core wire connection, and to handle each core wire and the holding core wire easily. It is intended to provide an adapter device in a low-cost optical cable connection storage cabinet that can perform safe connection processing work, greatly improve workability, eliminates the need for extra storage members, and It is.
