Description

Technical Field

[0001] The utility model relates to the field of optical fiber adapters, in particular to an anti-loosening optical fiber adapter. Background Art

[0002] Fiber optic adapters are passive devices used between fiber optic connector plugs and are often used in fiber optic communication systems. There are many types of fiber optic adapters. According to the connector type, they can be divided into LC fiber optic adapters, FC fiber optic adapters, SC fiber optic adapters, etc.; according to the usage mode, they can be divided into simplex fiber optic adapters and duplex fiber optic adapters; according to the manufacturing materials, they can be divided into bronze fiber optic connectors and ceramic fiber optic connectors.

[0003] However, the current fiber optic adapters have certain shortcomings when in use. The commonly used fiber optic adapters are usually provided with a mounting groove in the middle part of the outer shell, and a flange made of plastic is embedded in the mounting groove. The flange is provided with a mounting hole. In the actual installation process, the mounting hole is used for installation. This installation method usually requires a bolt to pass through the mounting hole, and a thread matching the bolt is provided on the mounting part of the mounting adapter. The bolt can be locked by turning the bolt. The operation is complicated and the installation time is long. When the fiber optic adapter is connected for use, it is not convenient to fix it. During use, it is necessary to use tools such as a screwdriver for installation. Moreover, the bolt is usually small in size and difficult to find after it falls. If the screwdriver cannot be found after installation, the user usually pulls it out directly with force, which easily damages the adapter. When it is pulled or hit by the outside, the bolt is small and it is easy for the fiber optic adapter to detach. The stability and firmness are poor. When it is subjected to improper external force impact, the bolt is easy to detach from multiple mounting holes due to the influence of the aforementioned external force, and it is easy to loosen. If the bolt is not fixed for a long time, the fiber optic adapter will detach, which is inconvenient to use. Utility Model Content

[0008] Furthermore, the height of the groove is smaller than the height of the shell.

[0009] Furthermore, the height of the elastic structure is smaller than the height of the shell.
