Urban rail transit 5G antenna optical cable cold-pressing installation auxiliary device

Abstract

The invention discloses an urban rail transit 5G antenna optical cable cold-pressing installation auxiliary device. The device comprises a tray, an LC connector and an optical fiber clamp, the inner walls of the two sides of the tray are slidably connected with the same arc-shaped plate. The bottom of the arc-shaped plate makes contact with the inner wall of the bottom of the tray, two springs aresymmetrically welded to one side of the arc-shaped plate, one end of each spring is welded to the inner wall of one side of the tray, first U-shaped grooves are formed in the two sides of the top ofthe tray and the top of the arc-shaped plate, and a circular plate is rotatably connected to one side of the tray. The device has the advantages that the device is compact in structure, small, exquisite, portable, easy to construct and operate, capable of saving more time compared with traditional hot melting, passive in construction, free of electricity or other precise instruments, free of special requirements for the operation environment, capable of being repeatedly used, capable of saving cost, free of a welding machine, capable of reducing cost, capable of achieving the antenna online rate of 95% and convenient to maintain and replace in the later period.

Description

technical field [0001] The invention relates to the technical field of cold-press installation of optical cables, in particular to an auxiliary device for cold-press installation of 5G antenna optical cables in urban rail transit. Background technique [0002] In recent years, the fifth-generation mobile communication system 5G has gradually become a hot topic in the communication industry and academia. Judging from the current development, there are two main driving forces for the rapid development of 5G. On the one hand, the long-term evolution of the fourth-generation mobile communication system 4G has been fully commercialized, and further research has been put on the agenda; on the other hand, the demand for mobile data users is growing explosively. The system may not be able to meet the needs of the future. Judging from the current situation, there is an urgent need to develop a new generation of 5G systems. [0003] The main advantage of the 5G network is that the d...

Problems solved by technology

[0005] Aiming at the problem of low antenna up-line rate, the research team members conducted a careful on-site comparison and analysis, discussed and refined the problem in depth, and found that the protective cover at the root of the optical fiber is not uniform, there is a gap in the optical fiber clamp cover, and the bare fiber exceeds the window of the LC connector. Aspects are the main reason affecting the first pass rate of 5G indoor antenna installation and commissioning
