When a connector is tightened with insufficient torque, electromagnetic field radiation from interconnected devices is increased. To elucidate the mechanisms of electromagnetic field radiation due a loose contact in a connector, we investigate the high-frequency electrical elements in contact boundary of a loose connector. On the basis of this result, we show the relationship between the high-frequency electrical elements and the electromagnetic field radiation from interconnected electric devices.
