Inserting core component, optical fiber connector and assembling method thereof and traction component

Abstract

The invention discloses an inserting core component comprising an internal shell, a spring, a porous inserting core, a multi-fiber optical cable, a sleeve and a heat shrink tube. The inserting core component is an independent integral part which is separated from the external shell of an optical fiber connector, and the external shell of the optical fiber connector can sleeve the inserting core component. A smaller multicore inserting core component can be rapidly assembled by all other parts of the optical fiber connector apart from the external shell and the external tail sleeve so that the multicore inserting core component can be easily pulled to pass a long and thin pipeline in a traction way. Besides, after the multicore inserting core component passes through the pipeline, the external shell and the external tail sleeve can be conveniently installed on the multicore inserting core component so as to form a complete multicore optical fiber connector.

Description

technical field [0001] The invention relates to a ferrule assembly, an optical fiber connector with the ferrule assembly, a pulling assembly with the ferrule assembly, and an assembly method for the optical fiber connector. Background technique [0002] In the prior art, the design of the enhanced multi-core optical fiber connector based on the porous ferrule is completed by processing and assembling all components in a controlled factory environment. When this design encounters an application environment with limited space (For example: components need to be passed through pipes with limited space), due to the relatively large head of the complete connector, it becomes very difficult to apply in an environment with limited space, and it is even impossible to achieve effective laying of optical cable components. [0003] In the prior art, the design and manufacturing process of the enhanced multi-core optical fiber connector generally adopts the following method (taking a co...

Problems solved by technology

[0006] a) Its size is large, and it is not easy to pass through the pipeline at the application site, especially when the space of the pipeline is limited, which makes it difficult or even impossible to lay the optical cable;

[0007] b) If the enhanced multi-core optical fiber connector pigtail connection scheme is adopted, that is, the optical cable is only passed through the duct on site, and then the optical cable is connected to a section of enhanced multi-core optical fiber connector pigtail prefabricated in the factory environment outside the duct, Although this method can also realize the function of optical cable connection, due to the relatively complex structure of the multi-core opti
