[0002] Fiber optic adapters, also known as fiber optic flanges or fiber optic connectors, are one of the most widely used optical passive components in fiber optic communication systems. Its main function is to achieve alignment and connection between optical fibers and ensure the highest connection performance between fiber optic connectors. Fiber optic adapters can convert between different types of fiber optic interfaces to achieve interconnection between different types of devices. In practical applications, fiber optic adapters play an important role in various fiber optic network scenarios, such as fiber optic network extension, fiber optic network connector conversion, and fiber extender applications. By using fiber optic adapters, the wiring and connection methods of fiber optic networks can be simplified, the reliability and performance of the network can be improved, and the needs of different scenarios can be met.

[0003] The optical fiber adapter usually includes an adapter housing, a sleeve, two optical fiber interfaces and a dust cover. The two optical fiber interfaces are set on the surface of the adapter housing. The optical fiber interfaces are used to connect with the optical fiber line. The dust cover is designed to protect the inside of the optical fiber interface from dust, dirt and other contaminants. It can play a dust-proof role when the adapter is not in use and ensure the cleanliness of the optical fiber interface when connected.

[0004] The adapter shell of the existing SC type fiber optic adapter usually has two functions, namely dust prevention and positioning. Both ends of the adapter shell are sealed with dust plugs to prevent dust from entering the sleeve and affecting signal transmission. The adapter shell can act as a flange to make it easier to insert the fiber optic plug. However, the adapter shell is usually made of plastic and has a thin structure. If it is squeezed by other objects, it is easy to cause the adapter shell to be damaged. Utility Model Content
