The application relates to the technical field of
optical fiber connectors, and discloses an anti-loosening
optical fiber connector which comprises a connector main body, a transmitting end fixedly connected to the side surface of the connector main body, a connecting block fixedly connected to the side surface of the connector main body away from the transmitting end, a clamping mechanism fixedly connected to the side surface of the connecting block away from the connector main body, a protective sleeve fixedly connected to the side surface of the clamping mechanism away from the connector main body, a self-
locking mechanism movably connected to one side of the protective sleeve close to the clamping mechanism, and a detection mechanism movably connected to the other side of the protective sleeve away from the clamping mechanism. The
optical fiber cable is placed in the limiting block and the
lower half screw rod, the upper half screw rod and the
lower half screw rod are in contact with each other, the
optical fiber cable is fixed between the upper half screw rod and the
lower half screw rod, finally the threaded sleeve is turned into the outside of the upper half screw rod and the lower half screw rod, the upper half screw rod and the lower half screw rod are fixed, the position of the
optical fiber cable is fixed, and the installation is more firm.
