Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber adapters, in particular to an optical fiber adapter that is easy to connect. Background Art

[0002] With the continuous improvement of user needs, fiber optic adapters are widely used in the field of optical fiber connection equipment. Their ends can be inserted with fiber optic connectors of different interface types to achieve conversion between different interfaces such as FC, SC, ST, LC, MTRJ, MPO, E2000, etc. To facilitate the connection of the connectors at both ends, the fiber optic adapter is connected to the fiber optic connector through the port. A sleeve is set between the opposing ports. The fiber optic connectors at both ends of the fiber optic adapter are respectively inserted into the corresponding ports. The optical fibers at the ends of the fiber optic connector heads are respectively inserted from both ends of the sleeve and aligned through the sleeve to avoid optical fiber misalignment and reduce loss.

[0003] Patent number CN2017218081642 discloses a fiber optic adapter with a built-in dust cover. The adapter includes an adapter body, a front cover assembly located at the front end of the adapter body, and a rear dust cover located at the rear end of the adapter body. The adapter body is mounted on a sleeve for connecting a fiber optic patch cord. The front cover assembly includes an adapter front cover, a rotating dust cover, and an elastic member. The adapter front cover has an opening for accommodating the rotating dust cover, which is elastically connected to the elastic member. The rotating dust cover has a force-bearing groove corresponding to the sleeve. When inserting a cable, the rotating dust cover rotates open under the thrust of the patch cord pin, allowing patch cord insertion and removal operations to be completed with one hand, improving wiring efficiency. The rotating dust cover is located inside the adapter, without increasing the adapter's volume, saving space. Before or after inserting or removing a cable, the rotating dust cover always rebounds to the closed position under the action of a spring, effectively preventing dust from contaminating the adapter.

[0004] However, in the above technical solution, the dust cover is a whole, so that the openings on both sides can only be opened and closed at the same time. However, in actual use, there is a need for single-side opening, which cannot be met by this solution. Utility Model Content
