The invention relates to electronic equipment and belongs to the field of equipment design. The electronic equipment comprises at least two diodes, a charging port and an electrical component, whereina power pin of the charging port is electrically connected with a positive electrode of a power supply port of the electrical component; a ground pin of the charging port is electrically connected with a negative electrode of the power supply port of the electrical component; a cathode of each diode is electrically connected with a first circuit separately, and an anode of each diode is electrically connected with a second circuit separately, wherein the first circuit is the circuit electrically connected between the power pin and the positive electrode of the power supply port; and the second circuit is the circuit electrically connected between the ground pin and the negative electrode of the power supply port. The problem that the circuit in a mobile phone is easily damaged due to thefact that surges are introduced into the mobile phone through a USB port of the mobile phone is solved; and the effect of providing the circuit in the mobile phone with protection to prevent the circuit in the mobile phone from being damaged by the surges is achieved.
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: ...
