AI Technical Summary

Technical Problem

The existing fiber optic module packaging structure, which uses screw connections, is susceptible to environmental factors, leading to signal transmission interference and connection point failure risks. Furthermore, the exposed connectors are prone to wear and tear.

Method used

The lower box and upper cover adopt a snap-fit connection structure, combined with the design of a protective shell and a magnetic cover to protect the fiber optic connector. It can be easily disassembled and assembled through snap-fit and magnetic attraction. The protective shell protects the fiber optic connector, and the magnetic cover opens automatically during use and closes automatically after use.

Benefits of technology

This achieves a stable connection of the fiber optic modules, prevents the influence of environmental factors, reduces connection point loss, and improves the reliability and ease of maintenance of the equipment.
