Problems solved by technology

[0002] With the popularization of the application of optical links, the application environment of optical fiber connectors is getting higher and higher. At present, the commonly used optical fiber connectors use threaded connections. This connection method is not stable enough, and the connection is easy to loosen; in addition The collimator in the beam expander connector is mostly fixed on the inner wall of the connector housing with glue, and there is no space for the collimator to float, which requires the collimator at both ends of the connector to be positioned very accurately, otherwise it will affect the optical fiber. signal transmission

Abstract

The invention discloses an optical fiber beam expanding connector, and the connector comprises a plug housing assembly, a cavity of the plug housing assembly is internally provided with a beam expanding assembly, the beam expanding assembly comprises a first collimator, the first collimator is sleeved with a ceramic sleeve, and the ceramic sleeve is sleeved with a protection tube; the socket connector comprises a socket shell, a second collimator is axially and movably arranged in a cavity of the socket shell, when the plug connector and the socket connector are connected in an inserted mode, the socket shell is inserted into the cavity of the plug shell assembly, the inner diameter of the cavity of the socket shell is matched with the outer diameter of the protection tube, and the socket connector is inserted into the cavity of the socket shell assembly. The end face of the first collimator is attached to the end face of the second collimator. The invention provides an optical fiber beam expanding connector, which adopts a steel ball unlocking structure, can realize quick insertion and extraction, and is reliable and durable.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to an optical fiber beam expanding connector. Background technique [0002] With the popularization of the application of optical links, the application environment of optical fiber connectors is getting higher and higher. At present, the commonly used optical fiber connectors use threaded connections. This connection method is not stable enough, and the connection is easy to loosen; in addition The collimator in the beam expander connector is mostly fixed on the inner wall of the connector housing with glue, and there is no space for the collimator to float, which requires the collimator at both ends of the connector to be positioned very accurately, otherwise it will affect the optical fiber. transmission of signals. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an optical fiber beam e...
