Study on Intermittent Fault Mechanism of Electrical Connector With Corrosion Degradation Under the Vibration Stress

With the continuous development of marine operations, the intermittent faults caused by the external salt fog environment threaten the safety of ship operations seriously. Among them, the intermittent fault of electrical connectors presents the major problem faced by ships. This article analyzed the mechanism of the intermittent fault of the electrical connector under salt-spray corrosion with and without vibration. In the meantime, the designs and vibration experiment of the electrical connector with corrosion degradation were carried out. In conclusion, the intermittent fault of the electrical connector is the main fault problem faced by ships.
