a fiber optic connector

Abstract

The invention discloses an optical fiber connector, which includes a plug, a socket and an extension cord, the plug includes a first optical cable, a first net tail, a first crimping ring, a first rear shell, a first ferrule assembly, and an open tube Fixer, open tube, first inner frame sleeve, first outer shell assembly, the socket includes a third optical cable, a tail sleeve, a third crimping ring, a fixing nut, a rubber sleeve, a third rear shell, and a third ferrule assembly , a third inner frame sleeve, a third outer shell assembly, the extension cable socket includes a second optical cable, a second net tail, a second crimping ring, a second rear shell, a second ferrule assembly, a second inner frame sleeve, The second shell assembly, the plug is connected to the socket, and when it needs to be extended, the connection is realized through an extension cable. The optical fiber connector of the present invention has a reasonable structure design, relatively few parts, high connection reliability, good sealing performance, and a connector Good resistance to pulling.

Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, and in particular relates to an optical fiber connector. Background technique [0002] Optical fiber connector is a device for detachable connection between optical fiber and optical fiber. It precisely butts the two end faces of optical fiber so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and due to its The impact on the system caused by the intervention of optical links is minimized, which is the basic requirement of optical fiber connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems. [0003] Existing outdoor optical fiber connectors with high protection level usually adopt dual-channel or multi-channel design. The dual-channel usually adopts 2PCS conventional LC indoor connectors, plus a waterproof protective he...

Problems solved by technology

[0004] In addition, the existing 4-core high-protection grade optical fiber connector has a small ferrule spacing (2.5mm), and the commonly used optical fiber end face cleaning tools interfere with the ferrule because the plug is too large (the minimum allowable spacing of the mainstream cleaning tools is 2.7 mm). mm), resulting in the inability to clean the end face of the optical fiber. At the same time, the design of the optical fiber connector in the prior art is complex, and the connection, fixing and docking are not precise and stable enough.
