Description

Technical Field

[0001] The utility model relates to the technical field of optical fibers, in particular to an optical cable butt fixing and protecting device. Background Art

[0002] From the initial development of liquid optical fiber to today's solid silk optical fiber such as glass optical fiber and plastic optical fiber, the development of optical fiber technology has a history of many years. At present, the application range of optical fiber is very broad, such as fiber optic temperature sensing, fiber optic communication, industrial control and other scenes, where glass optical fiber and optical cable can be seen. However, optical fiber with such a wide range of applications is made of glass, plastic and other silk threads with very small cross-sectional diameters, which makes the optical fiber itself very fragile and easy to break and bend, eventually leading to the break of the optical path. Although the optical cable is equipped with a protective layer to protect the internal optical fiber, when the optical cable is installed on some moving parts or exposed parts, the connection between the optical cables is not effectively protected, and the link between multiple optical fiber sections is still easy to break.

[0003] In the case of optical fiber failure, one of the main causes of failure is that the optical fiber connector is subjected to lateral force, resulting in the misalignment of the optical fibers at both ends or a gap in the interface. In a static environment, the optical fiber docking position is subjected to external force (such as stepping on) or the optical cable at the rear end of the connector is pulled, which will cause the docking surface to be misaligned or a gap to be generated. On moving parts, the connection position is more likely to fail after being affected by environmental forces such as acceleration and centrifugal force. In addition, under the action of environmental forces on moving parts, if the optical cable and connector are not securely fixed, they are easy to fall off the moving parts, causing the optical fiber transmission route to be interrupted; in severe cases, the detached optical fiber is drawn into the moving parts, causing the parts to get stuck and damaged, and then causing the entire system to shut down; even worse, it can lead to safety accidents, causing serious economic damage and personal safety. Therefore, it is necessary to develop a cable docking and fixing protection device. Utility Model Content
