4U0-144-core high-density optical fiber distribution frame

Abstract

The invention discloses a 4U0-144 core high-density optical fiber distribution frame. The bottom end of a top plate is fixedly connected with a distribution frame shell, one end of the distribution frame shell is rotatably connected with a cabinet door, and sliding mechanisms are installed on the inner wall of the distribution frame shell at equal intervals. Each sliding mechanism comprises a rectangular groove, a rotating shaft, a fixed wheel, a sliding plate, a movable plate, a limiting hole, a clamping plate, a limiting block, a positioning pin and a roller. According to the present invention, by the cooperation of the positioning pins, the limiting holes and the limiting blocks, the clamping plate is limited and fixed and can be fixed according to the length of a wire box, and the stability of the wire box is guaranteed; by the cooperation of the rectangular grooves and the sliding plates, the movable plates can slide out of the distribution frame shell conveniently; meanwhile, through the cooperation among the rotating shafts, the fixed wheels and the rollers, friction between the sliding plates and the rectangular grooves is reduced, the service life of the sliding plates isprolonged, and the sliding-out efficiency of the movable plates is improved, and therefore workers can conveniently and rapidly slide out of the movable plates, and the optical fibers in the wire boxcan be conveniently overhauled.

Description

technical field [0001] The invention relates to the technical field of optical fiber distribution frames, in particular to a 4U0-144 core high-density optical fiber distribution frame. Background technique [0002] Optical fiber distribution frame is a wiring connection device between optical cable and optical communication equipment or between optical communication equipment. It is used for the termination and distribution of backbone optical cables in the optical fiber communication system, and can easily realize the connection, distribution and scheduling of optical fiber lines. , with the increasing degree of network integration, a hybrid optical distribution frame integrating ODF, DDF, and power distribution units has appeared, which is suitable for small and medium-sized optical fiber to the community, fiber to the building, remote modules and wireless base stations. wiring system; [0003] However, the current optical fiber distribution frame lacks a supporting mecha...
