Technical Field

[0001] The utility model relates to the technical field of optical fiber connectors, in particular to an optical fiber connector with a joint anti-loosening function. Background Art

[0002] A fiber optic connector is a device that provides detachable or active connections between optical fibers. It precisely connects the two end faces of the optical fiber so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent possible, and the impact on the system caused by its involvement in the optical link is minimized. This is the basic requirement of a fiber optic connector. To a certain extent, the fiber optic connector affects the reliability and performance of the optical transmission system.

[0003] Conventional fiber optic connectors are connected and locked using plastic locks. However, as the number of plug-in and plug-out times increases and the material itself ages, it may become loose. At the same time, this type of material itself is easily damaged by external forces and loses its locking effect. It is also difficult to relieve external forces after the structure is connected to provide anti-bending protection for the connected optical fibers.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an optical fiber connector with a connector loosening prevention function is proposed. Utility Model Content

The fixing seat is provided with a locking ring around it, and a docking hole is opened in the middle of the locking ring. Moreover, a supporting sleeve is horizontally provided on one side of the locking ring close to the sealing tube.
