This invention relates to the field of electronic connectors and circuit protection technology, and discloses a protection method to prevent poor contact caused by metal electrolysis in spring probe connectors. The method includes a main control chip that sends a microsecond-level detection signal to the connector for monitoring. The signal pulse width is less than the electrochemical polarization establishment time threshold, and charge discharge is used to suppress the electrolytic reaction. After detecting liquid conduction, the graphene heating module is controlled to operate at a constant temperature, and the physical drying time is determined using the dynamic voltage division principle of thermal impedance. Heating is then maintained for a preset time to remove microscopic residual moisture. Finally, a cold-state insulation re-inspection is performed. After the connector naturally cools to ambient temperature, the insulation impedance is tested again, and power is restored only when the cold-state impedance meets the recovery standard. This invention avoids electrolytic corrosion caused by the monitoring process and effectively eliminates misjudgments caused by high-temperature false drying and salt moisture return, ensuring the electrical safety of the connector after recovery.
