[0076] The working principle of the splicing circuit in the embodiment of the utility model is as follows:

[0077] In the embodiment of the utility model, for the splicing circuit 10 including the first splicing power supply circuit 1021, when the first power supply voltage output by the power supply power source is the power supply control circuit 1012 of the first splicing power supply circuit 1021, the power supply control circuit 1012 converts the first power supply voltage to obtain a second power supply voltage and outputs it to one end of the first resistor R13 and the power supply end of the signal control circuit 1011, and provides the second power supply voltage to the seventh switch device of the target second splicing power supply circuit through the first resistor R13 and the second splicing interface P5, so that the seventh switch device of the target second splicing power supply circuit is turned on, which is equivalent to stepping down the second power supply voltage, so that the voltage output from the first end of the second splicing interface P5 is reduced. At this time The signal control circuit 1011 detects a low-level signal corresponding to the voltage outputted from the first end of the second splicing interface P5, pulls the low-level signal up to a high-level signal, and sends the high-level signal to the first pole of the fourth switch device Q5, so that the fourth switch device is turned on. The current direction of the fourth switch device is from the second pole of the fourth switch device Q5 to the third pole of the fourth switch device Q5. At this time, the first pole of the first switch device Q1 is equivalent to the input negative voltage, so the first switch device Q1 is turned on, and the body diode of the third switch device Q2 is also turned on, and the fifth switch device of the target second splicing power supply circuit is also turned on, and the body diode of the sixth switch device of the target second splicing power supply circuit is also turned on, which is equivalent to the target second splicing. The power supply control circuit of the power supply circuit is powered on, and then the power supply control circuit of the target second splicing power supply circuit converts the first power supply voltage to output the second power supply voltage to one end of the sixth resistor of the target second splicing power supply circuit, and provides the second power supply voltage to the second switch device Q6, so that the second switch device Q6 is turned on and the voltage output from the first end of the fifth splicing interface of the target second splicing power supply circuit is reduced. At this time, the current direction of the second switch device Q6 is from the second pole of the second switch device Q6 to the third pole of the second switch device Q6, which is equivalent to the first pole of the third switch device Q2 inputting a negative voltage. Therefore, the third switch device Q2 is turned on, and the signal control circuit of the target second splicing power supply circuit detects that the target second splicing power supply circuit is turned on. The low-level signal corresponding to the voltage outputted from the first end of the fifth splicing interface of the power circuit will pull the low-level signal up to a high-level signal, and send the high-level signal to the first pole of the eighth switching device of the target second splicing power supply circuit, so that the eighth switching device of the target second splicing power supply circuit is turned on, and the current direction of the eighth switching device of the target second splicing power supply circuit is from the second pole of the eighth switching device of the target second splicing power supply circuit to the third pole of the eighth switching device of the target second splicing power supply circuit. At this time, the first pole of the sixth switching device of the target second splicing power supply circuit is equivalent to the input negative voltage, so the sixth switching device of the target second splicing power supply circuit is turned on. At this time, the entire circuit is in a conducting state and can work normally.It can be seen that the utility model realizes the splicing of the splicing circuit by connecting the first splicing power supply circuit with the target second splicing power supply circuit, and / or by connecting the second splicing power supply circuit with the target first splicing power supply circuit, and energizes the splicing circuit under the control of the power-on control circuit, which can simplify the splicing operation of the splicing circuit, thereby helping to improve the splicing efficiency of the splicing circuit, and improves the splicing diversity and flexibility of the splicing circuit by providing a variety of splicing methods to choose from. It can also use the power-on control circuit to realize the power-on control of the splicing circuit, which is beneficial to improve the power-on efficiency of the splicing circuit and reduce the occurrence of short circuits in the splicing circuit. The cost of the splicing circuit can also be reduced by replacing buttons with power-on control circuits.
