The present disclosure relates to an electronic device, which belongs to the field of device design. The electronic device includes at least two diodes, a charging port and a power consumption component, wherein: the power pin of the charging port is connected to the positive pole of the power supply port of the power consumption component Electrically connected, the ground pin of the charging port is electrically connected to the negative pole of the power supply port of the electric component; the cathode of each diode is electrically connected to the first line, and the anode of each diode is respectively connected to the second Lines are electrically connected, wherein, the first line is a line electrically connected between the power supply pin and the positive pole of the power supply port, and the second line is an electric line between the ground pin and the negative pole of the power supply port. Connected lines. The disclosure solves the problem that the surge is transmitted to the mobile phone through the USB port of the mobile phone and easily damages the internal circuit of the mobile phone; it achieves the effect of providing protection for the internal circuit of the mobile phone and preventing the surge from damaging the internal circuit of the mobile phone.
Description
technical field [0001] The present disclosure relates to the field of device design, in particular to an electronic device. Background technique [0002] When the charger is charging the mobile phone, it is easy to generate a surge when the charger is connected to the power supply, and the surge is an instantaneous overvoltage exceeding the normal working voltage. The surge is transmitted to the mobile phone through the USB port of the mobile phone, and it is easy to damage the circuit inside the mobile phone. [0003] In order to prevent the surge from damaging the circuit inside the mobile phone, a measure of surge protection for the mobile phone is urgently needed. Contents of the invention [0004] In order to solve the problem that the surge is transmitted to the mobile phone through the USB port of the mobile phone and easily damages the circuit inside the mobile phone, the present disclosure provides an electronic device. Described technical scheme is as follows: ...
