Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information communication outlet for connecting a so-called portable station, which can be carried around and exchanges communication information, and more particularly to an optical line terminal structure in optical communication.
[0002]
[Prior art]
Conventionally, as a terminal structure of this type of optical line, for example, an end portion of an optical cable is raised from the basement inside a cylindrical support body that can be opened on an upper surface standing on the ground. An optical connector to be connected to is attached, housed and fixed in the support body, and covered with a lid. When using this facility, there are some which loosen bolts and pull up the optical connector part upward to connect the portable station with the optical connector part exposed. According to the description of Japanese Patent Laid-Open No. 10-90573, the upper part of the support standing on the ground can be separated vertically from the dividing surface, and the outlet portion of the optical terminal stored and protected by the cap on the dividing upper surface However, when the cap is separated upward, the outlet portion is viewed from the side to be connected to the portable station, and the cap is slid downward to be integrated with the support body. There is a structure that covers the outlet part and maintains water tightness, and a structure in which the cap is provided on the support body so as to be movable up and down serves as a lock mechanism and cannot be opened unless a special handle is used. .
[0003]
[Problems to be solved by the invention]
However, since the lid is closed by fastening a general bolt, the first prior art described above can be easily opened by anyone, so it may be broken by mischief, and is necessary in an emergency, etc. Occasionally, you may notice a malfunction and not use it. Also, when communicating, since the optical connector built in the case is pulled upward to connect to the portable station with the connection part exposed, it is unavoidable that an obstacle or the like directly hits the connection part. As a result, the connection part is disconnected or broken, making it unusable. In addition, it suffers from rain and snow under bad weather conditions, which not only hinders communication, but also floods the facility and cannot be used. For that reason, when leaving it connected for several days, it becomes necessary to provide a separate roof facility that surpasses rain and dew, or to enhance the security facility in the meantime.
[0004]
On the other hand, the second prior art has a lock structure in which the cap is opened only by using a special handle and is sealed in a watertight state and the outlet portion is stored and protected in the support body. In this case, it is possible to prevent damage caused by tampering. However, by sliding and separating from the support body and opening the cap upward, the outlet stored in the cap can be seen from the side of the cap, and the portable station However, there is a problem in that maintenance and management cannot be thoroughly performed during a disaster such as when a portable station has to stay connected for several days to exchange information. In other words, this facility, which is used for emergency communication in the event of a disaster, exchanges information while it is connected day and night, so if heavy rain or snow blows during that time, rainwater will blow into the cap. In such a case, the communication may be hindered, or the damage caused by the mischievous mischief during that time cannot be prevented.
[0005]
Accordingly, the present invention solves the above-described problems and provides a terminal structure of an optical line that is not affected by rainwater or snowfall even during use and is not damaged by mischief.
