Abstract
A detection circuit is provided, including a connector and a processing circuit. The connector comprises a first detection terminal and a second detection terminal. The second detection terminal is electrically connected to a first reference potential. The processing circuit is electrically connected to the first detection terminal and is used for receiving a power supply signal. When the connector is connected to a connecting port, the first detection terminal is electrically connected with the second detection terminal through the connecting port to form an electrical loop, so that the processing circuit detects a detection potential on the first detection terminal, and then determines whether the connector is correctly connected to the connecting port.
