A control device for a digital terminal, used to control a digital terminal. The control device comprises a main body (1) and a data cable (2) connected to the main body (1). An end of the data cable (2) is provided with a connector (21) to be inserted into and electrically connected to a charging interface or a headphone port of a digital terminal. The data cable (2) of the main body (1) of the control device is connected to the digital terminal by means of inserting the connector (21) into the charging interface or the headphone port of the digital terminal. In this way, the present invention enables a user to input a signal to the digital terminal by directly operating the main body (1) without directly contacting the digital terminal, thus minimizing influences on the digital terminal.
