AI Technical Summary

Technical Problem

Existing SFP connectors are prone to accumulating static charge during hot-plugging or in high-humidity environments, resulting in electrostatic voltage exceeding 1kV, which may damage the internal optoelectronic conversion chip.

Method used

An anti-static SFP connector structure was designed, which adopts a grounded metal shell, forms a low-impedance conductive path with the grounding component through a sliding guide bar, maintains contact pressure using elastic contacts and compression springs, prevents short circuits with insulating adhesive, ensures conductive stability, and fixes the metal shell with a clamping unit to prevent displacement.

Benefits of technology

It effectively avoids electrostatic discharge that could damage the internal chip, improves the reliability of the connector in hot-plugging or high-humidity environments, reduces maintenance costs, and solves the problem of metal shell displacement caused by vibration.
