Abstract
An electronic device includes a first electronic component and a second electronic component. The first electronic component includes a control unit and a first connector. A first pin group of the first connector includes an even number of first detect pins. Two of the first detect pins are respectively located at the two ends of the first connector. The second electronic component includes a second connector that matches with the first connector. A second pin group of the second connector includes an even number of second detect pins. When the first connector is electrically connected to the second connector, each of the first detect pins is electrically connected to each of the second detect pins to form a conductive path. All of the first detection pins and the second detection pins connected with one another in series form the conductive path. And a first end of the conductive path is coupled to ground via one of the first detect pins. A second end of the conductive path is coupled to the control unit via another one of the first detect pins.
