EPFU optical fiber unit resin filling device and filling method

Abstract

The invention provides an EPFU optical fiber unit resin filling device, which relates to the technical field of optical fiber unit production. The technical problem that production cost is increased due to the fact that a flat optical fiber ribbon is adopted when the number of optical fiber cores exceeds two is solved. The EPFU optical fiber unit resin filling device comprises an air nozzle (1), an overflow nozzle (5), a resin injection joint (6), a positioning pin (8), a resin cavity (9), a first fiber distribution plate (10), a second fiber distribution plate (11), a third fiber distributionplate (12), an inlet die (13), an outlet die (14) and a base (16). The method can be used for producing the circular optical fiber unit with more than two optical fiber cores. The concentricity of the cavity outlet and the die is ensured, and a favorable guarantee is provided for the optical fiber bundle to be located in the center of the optical unit.

Description

technical field [0001] The invention relates to the technical field of optical fiber unit production, in particular to an EPFU optical fiber unit resin filling device and filling method. Background technique [0002] With the popularization of air-blow laying of optical cables, the trend of miniaturization of optical cables is developing, and there are higher and higher requirements for the fiber density of optical cables. For home-type optical cables, due to the limitation of the number of optical fiber cores, it cannot be widely used in the scene inside or between buildings, and due to the lack of resources for laying pipelines or the size limit of the inner diameter of the pipeline, a small structure, light weight, fiber optic cable is required. High density fiber optic cable. [0003] However, if the number of cores of the optical cable exceeds 2 cores, most of the optical cable structures in the form of loose sleeves are used, while if tight sleeves (such as butterfly ...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of EPFU optical fiber unit resin filling device, by arranging the resin cavity with circular holes around in the base, to ensure the detachability of the optical fiber unit, and install fiber splitting boards at both ends of the resin cavity. Splitter board 2, using 4 positioning pins to locate the splitter board and the resin cavity, which ensures the concentricity of the splitter board and the resin cavity, provides a circular optical fiber ribbon production device, and solves the problem of excessive outer diameter of the finished optical fiber cable. The technical problem of high production cost
