Description

Technical Field

[0001] This utility model relates to the field of optical fiber connector technology, specifically to an optical fiber connector. Background Technology

[0002] The main function of fiber optic connectors is to quickly connect two optical fibers, enabling continuous optical signals and forming an optical path. Fiber optic connectors are also essential and widely used passive components in current optical communication systems.

[0003] In existing fiber optic connectors, the ferrule assembly is typically inserted into the connector body, while the outer shell slides onto the connector body. The fiber optic connector locks itself to the adapter by inserting into the connector body, allowing the groove on the connector body to engage with the elastic clamps of the adapter, thus enabling communication. During unlocking, pulling the outer shell moves the connector body, releasing the outer shell from the groove and disengaging the elastic clamps, thereby unlocking the connector.

[0004] However, most existing fiber optic connectors only use threads to press the connector ring against the cable body when fixing the fiber, which results in poor locking and fixing of the fiber and certain defects in use. Therefore, we propose a fiber optic connector to solve the problems mentioned above. Utility Model Content
