[0002] Because the plug and socket specifications of different countries are different, they are not universal. If you need to insert a plug into a socket that does not match the specifications, you need to use a travel converter. A travel converter is a conversion tool. When using it, the travel converter is inserted into the target socket, and then the target plug is inserted into the matching socket hole on the travel converter to achieve conversion. The emergence of travel converters has improved the convenience of people's life when traveling, especially when traveling across countries, there is no need to worry about the trouble caused by the plug of the electronic device you carry not matching the local power socket.

[0003] However, in the commonly used travel adapter with British standard pins and European standard pins, the European standard pins and the British standard pins will occupy a certain space inside the travel adapter, so the positions of the European standard pins and the British standard pins outside the travel adapter shell will form two separate occupied areas, such as Figure 1 As shown, the UK standard plugs and the European standard plugs are spaced apart along the length direction of the shell, and the shell is longer as a whole, resulting in a larger overall volume of the travel converter.
