On-site quickly-assembling optical fiber connector

Abstract

A on-site fast assembly optical fiber connector comprises a core, an inner liner, an outer liner, a tail sleeve and a tail base with a through space, wherein the tail base is formed by an upper and alower base shells jointed with each other, the core is a combination core provided with an optical fiber of a demanded length, the combination core contains a ceramic core head and a core sleeve, thecore sleeve is provided with a step hole, the tail of the ceramic core head is tightly plugged in the core sleeve, one end of the optical fiber is provided in the axle hole of the ceramic core head, the ends of the optical fiber are ground to be shaped, the core sleeve is tightly pressed in the tail base, the combination core, the tail base and a spring are provided in the inner liner, the tail ofthe inner liner is buckled with a stop catch of the tail sleeve, another end of the optical fiber can be connected with a traditional optical fiber connector or an another combination core. The invention has novel design, adopts a combination core with an optical fiber and adopts buckle method to connect the elements, therefore, when the combination core with an optical fiber is prepared, the on-site fast assembly optical fiber connector can be quickly assembled on site to improve construction efficiency and reduce the cost for laying and mounting optical cables.

Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, in particular to a field quick-assembled optical fiber connector used in optical fiber transmission systems to facilitate laying construction and installation of optical cables. Background technique [0002] At present, the on-site construction of optical cables in the optical fiber transmission system has always been difficult to construct and high in cost. The conventional construction method is to pre-bury the pipeline before laying the optical cable, then place the optical cable in place by mechanical traction, and then perform special optical fiber fusion to form a usable optical line system. Fiber optic cable fusion mostly uses fiber optic connectors assembled in the factory at one time, and then seals and strengthens the joints on site. Since the optical fiber matching liquid is used to complete the butt joint of the optical fiber, the loss of the butt joint is directl...

AI Technical Summary

Problems solved by technology

Since the optical fiber matching liquid is used to complete the butt joint of the optical fiber, the loss of the butt joint is directly related to the cutting quality of the optical fiber at both ends and the amount of the matching liquid. Evaporation and aging of the matching liquid make the docking plane connection unstable

[0003] At the same time, in the process of optical fiber fusion, it is necessary to have: optical fiber fusion machine, optical time domain reflector, optical power meter, a full set of special tools, construction vehicles, factory And power supply, etc., requiring multiple personnel to work at the same time, the efficiency is low, the construction cost is high, and the requirements for the construction environment are relatively strict

[0004] In the optical cable to the home FTTH (Fiber to the Home) system solution, due to the limitation of the building structure, it is difficult to adopt the conventional construction and docking optical cable method

In the construction process of optical cable laying, there is no relevant literature disclosure of optical fiber connectors that can be quickly assembled on site
