Optical fiber main distribution frame

Abstract

The invention discloses an optical fiber main distribution frame and belongs to the technical field of optical fiber distribution. The optical fiber main distribution frame comprises a frame body. Modules are disposed on the frame body. A support plate is disposed at the lower end of the frame body. A fixing seat is disposed at the lower end of the support plate. A rotating mechanism is disposed in the fixing seat. An insertion opening is formed in each module. A through hole is formed above each insertion opening. Light guide bars penetrate the through holes. A liquid crystal block is disposed between the front light guide bar and the rear light guide bar. A bulb is disposed at the rear end of each module. The radian of the tail end of the rear light guide bar is consistent with each bulb. Compared with the prior art, the optical fiber main distribution frame has the advantages that the main distribution frame can be moved or the angles of the main distribution frame can be adjusted according to actual needs, the light of the turned-on bulbs irradiates the rear light guide bar, the rear light guide bar is brightened, a user can conveniently determine a connection state, and the optical fiber main distribution frame is simple in structure, convenient and practical.

Description

technical field [0001] The invention belongs to the technical field of optical fiber distribution, in particular to an optical fiber main distribution frame. Background technique [0002] The optical fiber main distribution frame is widely used in optical fiber fusion splicing, wiring, scheduling, and testing optical communication terminal equipment between optical fiber access network optical cables. It is a hub for signal transmission, scheduling, and replacement between optical signal transceiver equipment. Optical signal scheduling, switching and other functions, according to different network layout methods, people have developed a variety of optical fiber distribution frames, common optical fiber distribution frames are mostly single-sided operation structures, and a small number of double-sided The side-operated optical fiber distribution frame is also limited to the terminal on one side, and the other side is only used for fiber routing management.

[0002] The optical fiber main distribution frame is widely used in the optical communication terminal equipment in the optical fiber fusion splicing, wiring, dispatching and testing between optical fiber cables in the optical fiber access network. It is the hub of signal transmission, dispatching and replacement between optical signal transceiver devices. Optical signal scheduling, switching and other functions, according to different network layout methods, people have developed a variety of optical fiber distribution frames, common optical fiber distribution frames are mostly single-sided operation structures, and a small number of double-sided The side-operated optical fiber distribution frame is also limited to the terminal on one side, and the other side is only used for fiber routing management. Now there are in-line modules and horizontal modules in the distribution frame, sockets are set on the modules, and on the upper side of the modules Installing grooves are arranged on both sides of the wall, and LED display lights are arranged in the placing grooves. The LED display lights are used for the user to confirm the connection status of the optical cable connection, but the upper part of the module is very thin, so the installation groove is provided. Due to the limited space, it is very inconvenient to install LED lights, and the processing defective rate is high

In addition, after the current optical distribution frame is installed and fixed, the position is determined, and it is very troublesome to move or adjust the direction
