SC type polarization maintaining optical fiber connector

Abstract

The invention discloses an SC type polarization maintaining optical fiber connector. The SC type polarization maintaining optical fiber connector comprises a shell and a fixing unit. The internal portion of the shell is hollow, the right end of the shell is fixedly connected with the left end of a threaded connector, and the threaded connector is in threaded connection with a tailstock; the fixingunit comprises limiting grooves, a fixing cylinder, limiting rods, clamping plates, a rubber pad and springs, the side of the right end of the fixing cylinder is fixedly connected with the inner sideof the shell, the side of the fixing cylinder is provided with two limiting grooves which penetrate the side of the shell, there are two clamping plates, the sides of the left ends of the two clamping plates are provided with limiting rods, the two limiting rods are slidingly connected with the two limiting grooves, springs are respectively arranged at the four corners of the upper surface of theclamping plate at the lower side, the upper ends of the four springs are fixedly connected with the four corners of the lower surface of the clamping plate at the upper side. The SC type polarizationmaintaining optical fiber connector can conveniently and rapidly fix the optical fiber in the connector, is good in tensile and can be conveniently detached and reused.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an SC type polarization maintaining optical fiber connector. Background technique [0002] Polarization-maintaining optical fiber transmits linearly polarized light, which is widely used in various fields of national economy such as aerospace, aviation, navigation, industrial manufacturing technology and communication.
