TECHNICAL FIELD

The utility model relates to the technical field of power converters, in particular to a conversion and conduction structure for a power converter.

BACKGROUND ART

Since the standards for the sockets in each country are not completely uniform, a plug cannot be universally used all over the world. When people go to different countries, it is necessary to configure a plug corresponding to the country so as to supply power for portable electronic devices. If going to several countries at a time, consumers have to take power plugs corresponding to several countries, which causes great trouble for people who travel across countries or have a business travel.

As a result, multi-country power plugs are commonly available on the market that can be adapted to different national socket standards. It is disclosed in Chinese patent for invention (Patent No: 201010183801.8) that a plurality of pins of different specifications are grouped on the same power converter. However, the two groups of pins, American (US) pins and Australian (AU) pins, have only two legs, i. e. without ground wire pins. Although this power converter reduces the internal volume when reducing the number of legs, it has the risk of electric shock and leakage when used in high-power electrical appliances, which has low safety and does not meet the safety standards.

If ground wire pins are provided, the internal conduction structure is more complicated and more bulky, which is inconvenient for people to use in the travel.
