The device is characterized in that the device achieves the auxiliary heat dissipation effect, facilitates the quick switching of circuits, facilitates the line connection, facilitates the fixing of connecting lines, guarantees the line safety, achieves the uninterrupted power supply during the switching of the circuits, and improves the overall cruising ability.

Description

technical field [0001] The invention relates to the field of dual power supply, more specifically, to an autonomous switching dual power supply device. Background technique [0002] The dual power supply is derived from two power sources, and there are two feeder lines; the alternate use of the power supply part can be used as a backup power supply, and it can also improve the overall battery life when used on some mobile devices, but the dual power supply is in the switching circuit In the process, it is easy to cause short-term power supply. Interruption of power supply may affect the equipment and internal electrical components that are powered. Long-term use may cause damage to some electrical components and affect the use. However, the conventional way of switching power supply through switches is relatively slow, resulting in switching circuits that need to restart the equipment system, which affects the use of equipment. Therefore, the present invention improves the a...
