Novel sealed optical cable splice box free of cable breaking and application method thereof

Abstract

The invention discloses a novel sealed optical cable splice box free of cable breaking and an application method thereof, and relates to the technical field of fiber optical communication equipment. Asemi-cylindrical connecting pipe and a split cover nut are adopted to a cable inlet and a cable outlet. The semi-cylindrical connecting pipe and the split cover nut are of a split and non-symmetric structure. The outer wall of the semi-cylindrical connecting pipe of a box body top cover is smooth. An outer thread matched with an inner thread of the split cover nut is arranged on the outer wall ofthe semi-cylindrical connecting pipe of a bottom box. The unavoidable problem that the cover nut can not be tightly screwed caused by light deformation of a box body during injection molding is solved. The split-type structure achieves the functions of direct optical cable penetrating and draw-out fusion and guarantees the sealing performance of the whole splice box. The novel sealed optical cable splice box further comprises split plastic push blocks. The split plastic push blocks are pushed in the semi-cylindrical connecting pipe, the split cover nut is screwed, the split plastic push blocks are adopted to extrude an elastic sealing rubber body, and therefore the elastic sealing rubber body deforms to seal a seam to achieve the sealing effect, and sealing performance of the box body isfurther improved.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication equipment, in particular to a novel sealed optical cable splice box without broken cables and a method for using the same. Background technique [0002] As one of the important components in the optical communication network, the optical cable splice closure is mainly used for protective splicing and optical fiber distribution between two or more optical cables. However, most of the mechanically sealed optical cable splice closures currently on the market can only achieve simple cutting and splicing functions. All optical cables need to be cut and then welded, which cannot meet the needs of uncut optical cable splicing. This not only increases the construction time and the cost of optical fiber fusion, but also affects the communication quality. However, if the cable entrance and exit are designed as a symmetrical split structure, when the box body is injected as a whole, the ...

AI Technical Summary

Problems solved by technology

However, most of the mechanically sealed optical cable splice closures currently on the market can only realize the simple cutting and splicing function. It is necessary to cut all the optical cables and then perform fusion splicing, which cannot meet the needs of uncut optical cable splicing.

This not only increases the construction time and the cost of optical fiber fusion, but also affects the communication quality

However, if the cable inlet and outlet are designed as a symmetrical split structure, when the box body is injected as a whole, the box body will be slightly deformed, causing the cover nut to be unable to be fully tightened, which will affect the sealing of the optical cable splice box
