Abstract

The invention relates to a cable with a plugging and unplugging detection function and a corresponding electronic device. The cable comprises a first interface, a second interface, a sensor and a processing circuit. The sensor is used to detect whether the first interface and/or the second interface are inserted into the device interface, and the processing circuit is used to generate a digital detection signal. The cable can also include a power line, which is connected to the power supply terminal of the main device interface so that the processing circuit is powered by the main device interface, or powered by a rechargeable battery connected to the power line. The cable of the invention has simple structure and low cost, and can easily recognize plugging and unplugging of the cable without redesign or modification the electronic device interface.
