Electronic equipment, data line and connecting assembly

The utility model relates to electronic equipment, a data line and a connecting assembly, and the electronic equipment comprises a sensor which comprises a first line; the first port comprises a first terminal, and the first terminal is arranged on the first circuit; wherein the sensor detects detection capacitance values of the first circuit and a circuit connected with the first circuit; when the detected capacitance value is greater than or equal to a first threshold value, the first port is in a detection state; and when the detected capacitance value is smaller than the first threshold value, the first port is in a zero level state. The sensor for detecting the detection capacitance value is arranged on the electronic equipment, and the detection capacitance value is compared with the first threshold value, so that the insertion of the external equipment into the first port is accurately detected, the first port is prevented from being kept in a high-level state for a long time, electrochemical corrosion
