mpo fiber optic connector

Abstract

The invention relates to an MPO (Multi-fiber Push On) optical fiber connector. The connector comprises an inner shell and an outer shell movably sleeved on the inner shell back and forth, wherein theinner shell is provided with an inner cavity; a core insert, a spring and a spring limiting seat which is used for limiting the spring are disposed in the inner cavity; the spring limiting seat is inserted at a rear of the inner cavity; the spring limiting seat comprises a limiting seat body; a side surface of the limiting seat body is provided with a buckling bulge in interference fit with a cavity wall of the inner cavity when the spring limiting seat is inserted into the inner shell; and a side wall of the inner shell is provided with a buckling recess in snap fit with the buckling bulge when the spring limiting seat is assembled in position. The spring limiting seat and the inner shell are connected together in a forced assembly manner, and the spring limiting seat compresses the spring located in the inner shell. Compared with the prior art, the spring limiting seat in the invention is not subject to compressive deformation in the forced assembly process, and the problem of connection failure of the optical fiber connector caused by loosening of a hook due to deformation of a cantilever in the prior art is solved.

Description

technical field [0001] The invention relates to an MPO optical fiber connector. Background technique [0002] With the rapid development of data communications such as big data and cloud computing, the requirements for network bandwidth are increasing in a blowout manner, which in turn puts forward higher requirements for the density of optical fiber networks. Traditional optical fiber wiring and wiring cannot meet the needs of development. Optical fiber connectors can realize the connection, distribution, and transfer between different optical fibers. Among them, the MPO series optical fiber connectors have many advantages such as high connection density, stable and reliable performance, small size, convenient operation, and easy wiring management. They are widely used in signal field of transmission or data transmission. [0003] An optical fiber connector is disclosed in the utility model patent with the authorized notification number CN202453542U, which includes an oute...
