AI Technical Summary
The existing fiber optic connectors lack waterproof components at the connection between the fiber optic connector and the coupler, and are not convenient for further fixation, resulting in easy falling off at the connection.
A waterproof fiber connector is designed. By fixing a rectangular frame on the fiber connector and setting a protective case and sealing gasket on the coupler, the conflict between the sealing gasket and the protective case and the cooperation between the L-shaped rod and the clamping rod are used to achieve sealing and fixing between the fiber connector and the coupler.
The seal between the optical fiber joint and the coupler is achieved to prevent moisture from infiltration. At the same time, through the coordination of the clamp rod and the L-shaped rod, a stable connection between the optical fiber joint and the coupler is ensured to avoid falling off.
