Research on Intermittent Fault Dynamic Characteristic based on Electrical Connector

Intermittent faults usually occur under the condition of vibration stress, and are often accompanied with damage degradation of the component. Based on the electrical contact structure of electrical connectors, the influence impacts on intermittent fault of electrical connector have been analyzed. Under vibration stress, the mechanical model of the electrical connector is built considering the connection relationship among its components. The dynamic characteristic of the electrical connector working state has been studied through simulation analysis and experiments. The results have shown that the working state of the electrical connector is strong related to the environment vibration stress.
