Abstract: The present utility model discloses a conversion and conduction structure for a power converter, comprising the power converter including an upper cover of a main body, a lower cover of the main body, a bracket, a UK-standard pin assembly, a US-standard pin assembly, a hybrid plug assembly of the type CEE7/7, a CN-standard or an AU-standard pin assembly; Plugs in different countries are correspondingly connected in conduction with pins of different national specifications, especially ground wires in plugs in different countries are connected in conduction with pins of ground wires of different national specifications, thereby improving the safety of the power converter.

Abstract: The present utility model discloses an overload prevention device for a multi-country power converter, the UK-standard pin assembly and the US-standard pin assembly are respectively connected with the lower conductive piece in a plug-in manner; the upper conductive piece comprises an clamping part of the upper conductive piece capable of clamping and conducting the upper part of the fuse tube; and the upper conductive piece is electrically connected to the socket hole. It is easy to pull out and mount the utility model. The structure is stable after being mounted. The conduction is smooth and the safety is high, which effectively protects the circuit of the power converter to prevent overload of the circuit and the problem of people pulling out incorrectly during use. The volume of the product can also be made smaller.

Abstract: The invention discloses a foldable plug mechanism applied to a multi-national power converter, comprising: a mounting base; a plug assembly rotatably disposed on the mounting base; a locking assembly disposed on the mounting base for locking the plug assembly; and at least one elastic member disposed between the plug assembly and the mounting base. The foldable plug mechanism applied to a multi-national power converter disclosed in the invention can freely fold and unfold a plug assembly according to needs. When folded, the plug mechanism has a small volume, occupies a small space, is well accommodated, is convenient to be carried, and is particularly convenient to be carried abroad. When folded, the pins of the plug assembly are less likely to come into contact with other items without phenomenons of dust, scratching, damage or bending.

Abstract: The present invention discloses an anti-electric shock mechanism for a power converter comprising a protective tube provided in the power converter and further comprising a locking guide block provided in the power converter, and a protective holder for mounting the protective tube, wherein a locking groove is formed on the protective holder, and a locking part inserted into the locking groove is provided on the locking guide block. The anti-electric shock mechanism for the power converter provided by the present invention can prevent the risk of electric leakage and electric shock when the power converter is used, whether the protective tube has not been pulled out, is partially pulled out or has been completely pulled out, so as to improve the safety of the power converter.
