Large-capacity optical cable cross-connecting cabinet capable of longitudinally expanding without disassembling

Abstract

The invention discloses a large-capacity optical cable cross-connecting cabinet capable of longitudinally expanding without disassembling. The large-capacity optical cable cross-connecting cabinet comprises a cabinet body, a base, an expansion box and a cabinet cover, wherein connecting grooves are arranged at the top of the cabinet body, connecting grooves are arranged at one end of the expansionbox, and connecting pieces are arranged on the other end of the expansion box; when needing to perform expansion, the connecting pieces on the expansion box can be arranged in the connecting grooveson the cabinet body only by disassembling the cabinet cover, and then the cabinet cover is arranged in the expansion box to realize longitudinal expansion and reduce the workload of the expansion construction without producing noise and dust pollution, and the work efficiency is improved. By adopting modular arrangement, a distribution optical cable welding unit, a trunk optical cable welding unitand a splitting frame are orderly arranged on a mounting plate from top to bottom; and a main wiring frame is further arranged on the mounting plate, so that the wiring is more convenient, and the optical fiber is located in the wiring fame after the wiring, the later wiring personnel can arrange wires more clearly, the mounting and the later maintenance are convenient, and the space utilizationefficiency in the optical cable cross-connecting cabinet is improved.

Description

technical field [0001] The invention relates to the field of optical cable transfer boxes, in particular to a large-capacity optical cable transfer box that does not need to be disassembled for longitudinal expansion. Background technique [0002] The optical cable transfer box is a transfer device installed outdoors to provide cable termination and jumper connection for the backbone layer optical cable and the distribution layer optical cable. Connect the backbone layer optical cables with the distribution layer optical cables. At present, the optical cable transfer box equipment purchased by domestic operators is customized, and the equipment structure and capacity are fixed. There are usually three common specifications of 144-core (and below) single-sided, 288-core single-sided, and 576-core double-sided. [0003] In order to cooperate with the advancement of the operator's optical access network network evolution and meet the requirements for dual uplinks of sinking O...

Problems solved by technology

[0004] At present, the horizontal expansion method is adopted. The expansion types are divided into single-sided optical cross-connection expansion to double-sided optical cross-connection and double-sided optical cross-connection expansion to three-sided optical cross-connection. The horizontal expansion method needs to remove the original transfer box and base, and reinstall the expanded transfer cross-connection box, resulting in the need to measure each box that needs to be expanded, with a lot of test data and a heavy workload; expansion is easily affected by the space around the box, and this expansion plan can only be implemented when there is enough space around the box; for different If the internal installation size of the cabinet is different, different new cabinets need to be customized and produced, which is not convenient for mass production; when disassembling the cabinet, the workload is heavy, and the stability of the original optical path is easily affected during the operation Seriously, it will cause the optical path to be blocked; the operation is difficult, and the stability of the original optical path must be ensured while removing the original box shell, and then a new cement base is constructed, and then the new box is installed; during the construction process, noise, The dust is serious, and there will be more garbage generated after construction, which is not conducive to environmental protection

[0005] At the same time, in the prior art, the division of the optical cable working area inside the optical cable transfer box is not obvious, and there is no physical separation between them. When installing the optical cables, the optical cables are easy to intertwine with each other, which is relatively mixed, and it is easy to directly affect the construction and storage. The operation and wiring optimization of the fiber work space reduces the space utilization rate. At the same time, when a fault occurs inside the optical cable transfer box, the internal lines are intricate and difficult to find the fault area in time, which reduces the maintenance efficiency.
