Abstract

The invention provides an optical fiber connector plug, an optical fiber adapter and an optical fiber connector, relates to the technical field of optical fiber communication, and aims at solving theproblem of poor butt joint of two optical fiber connector plugs in the optical fiber adapter. The optical fiber connector plug comprises an optical fiber, an insertion core, a connecting piece and a guide cylinder, the insertion core is fixedly connected with the optical fiber, the connecting piece sleeves the optical fiber and is fixedly connected with the insertion core, and the guide cylinder sleeves the connecting piece and surrounds the insertion core; in a butt joint state, the front end of the insertion core convexly extends out of the front end of the guide cylinder; an optical fiber adapter flange and an insertion core butt joint sleeve are included, a first cavity, a sleeve accommodating cavity and a second cavity are communicated in sequence in the flange, a first insertion groove formed in the periphery of the first cavity and a second insertion groove formed in the periphery of the second cavity are formed in the flange, and the insertion core butt joint sleeve used for enabling two insertion cores to be in butt joint in the insertion core butt joint sleeve is arranged in the sleeve accommodating cavity; the optical fiber connector comprises the optical fiber connectorplug and the optical fiber adapter, and the coupling efficiency of optical signals is improved.

Description

Technical field [0001] The present application relates to the field of optical fiber communication technology, and in particular to an optical fiber connector plug, an optical fiber adapter and an optical fiber connector. Background technique [0002] With the development of communication technology, optical fiber transmission is increasingly used in communication systems. When the use of optical fibers increases, how to connect two optical fibers repeatably and quickly becomes more and more important. At present, optical fibers are generally connected through optical fiber connectors. The optical fiber connectors include optical fiber adapters and two optical fiber connector plugs. The optical fiber connector plug is connected to one end of the optical fiber, and the two optical fibers each pass through an optical fiber connector plug. Connect to a fiber optic adapter. [0003] Each end of the fiber optic adapter is provided with an opening that is adapted to the fiber opt...
