Optical cable splicing protective device and installation method thereof

Abstract

An optical cable splice protection device, comprising a housing having a cover (100) and a base (200), and a fiber coil assist device (400) mounted in the base (200) of the housing. The fiber coil assist device (400) comprises a bottom piece (401), flexible flaps (410, 420) detachably mounted on the top of the bottom piece (401), and an elastic eccentric compressing element (403) mounted in the base (200) of the housing and used for applying an eccentric compressing force on the bottom piece (401). Under the effect of the eccentric compressing element (403), the bottom piece (401) presses on an optical fiber ferrule (13, 23) of an optical cable (10, 20) to be spliced, and is used for preventing the optical fiber ferrule (13, 23) from becoming coiled and disorderly; furthermore, the optical fiber (12, 22) of the optical cable (10, 20) to be spliced is coiled above the bottom piece (401) and along the no-bending-loss path defined by the flexible flaps (410, 420) and is constrained in an orderly manner at a suitable position. The device prevents twisting and clutter, increasing optical fiber storage space.

Description

technical field [0001] The invention relates to an optical cable splice protection device. Background technique [0002] In the optical communication network, due to the limited length of the optical cable and the need for branching and cross-connection of the optical cable on the transmission line, it is necessary to protect the splicing and splicing of the optical cable to ensure that the splicing can resist changes such as temperature, humidity, and mechanical pull. External factors, to achieve round-the-clock work. The usual practice is to use optical cable splicing devices to provide conditions for optical cable splicing, branching and cross-connection, and to achieve integral protection for splicing. The overhead of various optical cables, the straight-through connection of the pipeline, the branch and the cross-connection often use the optical cable connection device to meet the connection protection needs of the interconnection between the main line of the optical c...

AI Technical Summary

Problems solved by technology

The disadvantage of the existing optical cable splicing device is that it is necessary to fix the reinforcing ribs of the optical cable one by one in the base, which brings inconvenience to on-site installation

At the same time, the cover and the base are fixed by multiple screws, which also brings inconvenience to on-site installation

Moreover, in the existing optical cable splicing protection device, there is no structure for managing the optical fiber sleeve, which leads to the phenomenon that the optical fiber sleeve and the optical fiber are easily entangled and messy
