Description

Fiber optic terminal box

The embodiment relates to an optical terminal box.

The data transmission method using an optical fiber is much superior to the conventional method of transmitting data using an electrical signal in terms of transmission speed and the quality of the transmitted signal, and thus is widely used in the communication field.

Since a general optical fiber is manufactured by pulling a thin and long transparent dielectric such as quartz glass or plastic, it has a disadvantage in that the strength is relatively weak due to the nature of the material. For this reason, the outer surface of the optical fiber is coated with a cushioning cover or the like to form a cable.

The optical terminal box performs the function of connection and distribution between the external optical path and the subscriber transmission device. When a part of the incoming optical fiber is connected to the optical fiber of the optical adapter and distributed to the transmission device of the subscriber in the short distance, the remaining optical fibers of the optical cable are in the form of optical cables. It is fetched back to the network and distributed to the subscriber's transmission device at a long distance.

The Republic of Korea Utility Model Publication No. 20-2009-0005383 (published on Jun. 3, 2009, hereinafter referred to as this document) describes an optical terminal box.

The optical terminal box of the present document discloses a configuration including adapters for fixing the connector to the side wall of the housing. These adapters are placed in a slot penetrating the side wall. During the process of attaching and detaching the connectors to the adapter, due to the nature of the product made of steel, a hole is drilled large so that the adapter shakes in the housing. When the cover is opened and closed, the upper and lower plates of the product There is an inconvenient problem of using it as a handle by attaching a bolt or clip separately when combining them.
