Description

Technical Field

[0001] The present invention relates to the technical field related to optical fiber connectors, and in particular to an optical fiber connector and an optical fiber connector assembly. Background Art

[0002] Fiber optic connectors are devices that provide detachable (movable) connections between optical fibers. They precisely connect the two end faces of the optical fibers to maximize the coupling of the light energy output by the transmitting fiber to the receiving fiber, while minimizing the impact on the system caused by their involvement in the optical link. This is the basic requirement of fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems.

[0003] The existing Chinese patent document with publication number CN109425937A discloses a fiber optic connector, which comprises: an outer housing; an inner housing mounted within the outer housing; a fiber optic ferrule housed within the inner housing; an optical cable extending into the inner housing and connected to the fiber ferrule; and an elastic tail boot wrapped around the connection between the optical cable and the fiber ferrule and a portion of the optical cable adjacent to the connection. A sealing structure is provided between the rear end of the outer housing and the elastic tail boot to achieve a seal between the outer housing and the elastic tail boot.

[0004] However, the fiber optic connector socket in the above solution is relatively simple, and some fiber optic connector sockets may not always be plugged with fiber optic connectors. In some environments with high dust content, dust may easily adhere to the end face inside the fiber optic connector socket, which will cause the fiber optic connector socket to affect the transmission stability of the signal at the connector during subsequent use, thereby causing a certain degree of impact on the normal operation of the optical fiber. For this reason, the present invention proposes a fiber optic connector and a fiber optic connector assembly to solve the above problems. Summary of the Invention
