Abstract:
1. A connector device having a counter thereof, comprising: a connector for receiving a power signal every time the connector is plugged into an electrified device; a micro control unit for outputting data, clock, and drive signals after receiving the power signal from the connector, wherein the micro control unit comprises a first micro-controller, a second micro-controller, a battery, a resistor, and a reset switch; a detecting pin of the first micro-controller is connected to a power pin of the connector for collecting the power signal; a data exchange pin of the first micro-controller is for outputting an actuating signal to a data exchange pin of the second micro-controller for controlling the second micro-controller to output the drive signal; data and clock pins of the first micro-controller are for outputting data and clock signals; power pins of both the first micro-controller and the second micro-controller are coupled to the battery via the resistor; a reset pin of the second micro-controller is grounded via the reset switch; an encoder for receiving and encoding the drive signal from the second micro-controller, and then outputting encoded signals; a display drive unit for counting number of times the connector has been plugged-in, the number of times adding one every time the display drive unit receiving the data and clock signals from the second micro-controller, wherein the display drive unit comprises a plurality of serial input/parallel output shift-registers, date and clock pins of each shift-register are connected to the data and clock pins of the first micro-controller, and the shift-registers count the number of times the connector has been plugged-in, after receiving the data and clock signals from the first micro-controller; and a display unit displaying the number of times the connector has been plugged-in, after the display drive unit receiving the encoded signals from the encoder.
