Description

Technical Field

[0002] Fiber optic is short for optical fiber, a fiber made of glass or plastic that can be used as a light transmission tool. For ease of use, a fiber optic connector is usually used to precisely connect the two end faces of the fiber optic cable to maximize the coupling of the light energy output by the transmitting fiber to the receiving fiber. Fiber optic interfaces are usually required to connect optical fibers. Existing fiber optic interfaces are simply connected through plug-in connection and clamped with elastic clamps. Sometimes they become loose, causing the fiber to fall off, resulting in data loss and connection instability. Even if a fiber optic interface with a fixed connection exists, its connection method is relatively complicated and often requires bolts to fix the interface. Therefore, we propose a fiber optic interface device that prevents it from falling off. Utility Model Content
