Drum membrane type optical fiber splicer capable of being repeatedly opened to be used

Abstract

The invention discloses a drum membrane type optical fiber splicer capable of being repeatedly opened to be used. The drum membrane type optical fiber splicer capable of being repeatedly opened to be used comprises an insertion core assembly, a box assembly, a shell assembly, a spring and an opening cover; the insertion core assembly and the box assembly are packaged in the shell assembly; the spring is arranged between the box assembly and the shell assembly; the box assembly comprises a box, a box cover, a guide wire block and a guide wire body; the box comprises a box body which is provided with a drum membrane cavity; two ends of the drum membrane cavity are communicated with the insertion core and guide blocks respectively; the side of the drum membrane cavity is provided with a drum membrane which is pressed to reduce the cross-sectional area of the drum membrane cavity; the periphery of the drum membrane is connected with the box body through a floating rib; a V-shaped groove is formed in the drum membrane cavity; and the box cover acts on the drum membrane through a locking membrane. The fixing action force which is applied by the optical fiber splicer to spliced optical fibers is distributed in a balanced way, and the twisting misplacement of the spliced optical fibers can be avoided; and moreover, a structure of sealing splicing points is adopted, so the splicing points are clean, and the erosion and interference of pollution can be avoided.

Description

technical field

[0001] The invention relates to a connection device for optical fiber installation, which seals the V-shaped groove part of the ferrule assembly in the tympanic cavity, drives the tympanic membrane with a spring clamp to compress the optical fiber, and can be opened and used repeatedly. Fiber splices with pre-preset or non-preset fiber splicing methods. Background technique

[0002] At present, there are mainly three ways to fix the optical fiber in the quick connection device products for re-openable use.

[0003] The first is to align and fix the two optical fiber ends by pressing the folded metal sheet to realize the butt end of the optical fiber; the second is to realize the butt end of the optical fiber by pressing and fixing the plastic block to fix the optical fiber; the third is to achieve the end of the optical fiber by The box-built gland presses the floating block to compress the V-shaped block to fix the optical fiber to realize the butt-end of t...
