Technical Field

the invention discloses a multi-voltage output power adapter, and particularly relates to an improvement aspect of a power adapter structure.

background

The power adapter has the characteristics of low unit price and small size and can be suitable for use in multiple occasions. However, in a factory operation environment, stations are crowded, one station usually needs a plurality of power adapters, the situation that the number of the power adapters is too many and the interfaces of a mains supply socket are not enough is often caused, and the socket is fully connected with a plug, so that a large amount of working pressure is brought to 6S arrangement, and an electric board is easily damaged or even a fire disaster is caused due to the similarity of output ends in the using process. The multi-voltage output power adapter can reduce the use of charging interfaces, and can be matched with output female connectors with different interface diameters to distinguish different voltage outputs and avoid using wrong power supplies.
