Abstract
A data cable between two electronic devices includes a first interface comprising a first metal shell and a ground end; and a second interface connected to another electronic device comprising a second metal shell, a ground end and an identification end. The data cable includes a detection circuit detecting voltage difference between the first metal shell and the ground end, and the detection circuit comprises an output end connected to the identification end of the second interface. An electronic device using the data cable detects any current leakage in an external electronic device. When the host has current leakage, the electronic device cuts power from the host and prevents data exchange, preventing damage or loss.
