Description

Technical Field

[0001] The invention relates to the technical field of optical fiber connectors, and in particular to a high-stability circular optical fiber connector. Background Art

[0002] A fiber optic connector is a device that makes a detachable (movable) connection 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, 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] Existing fiber optic connectors are usually connected to fiber optic adapters through a threaded structure. During the threaded connection, the operator is required to continuously rotate the traction cap to drive the fiber optic connector to connect with the fiber optic adapter. However, the operator's hand strength is limited. When the traction cap is rotated to a certain extent, it is difficult to continue to rotate it with the hand strength. However, the connection force of the traction cap is still relatively small for the connector. During use, it is easily affected by the vibration of the equipment, which may lead to loosening. Therefore, this connection method is not only time-consuming and labor-intensive, but also easily affects the fiber optic transmission effect. Summary of the invention

Therefore, this connection method is not only time-consuming and labor-intensive, but also easily affects the optical fiber transmission effect.
