1. Technical Field
The present invention relates to an adapter, and in particular, to a multinational adapter structure which is portable, of high security and can be conveniently operated to conform to various plugs standard specification of different countries.
2. Background Art
With the continuous development of social economy, people travel abroad or go on a business trip abroad and the like more and more frequently. Hence, they need to take along with certain communication equipment or electrical devices such as notebook computers, mobile phones, MP3, household appliances and other electronic products. Due to the presence of difference in various sockets specifications of US, UK, Australian, and European and the like, the portable electronic products may not be used when moved to another country. Therefore, a multinational adapter is needed on a trip abroad. People are rather reluctant to use the conventional adapters due to their large sizes and inconvenience in operation. Further, the electrical pin sets of many power adapters are stored in a folded manner nowadays. In order to facilitate screwing out of the electrical pins, the electrical pin group still is designed as of which a partial is exposed. However, some of the exposed portions are prone to collision and deformation problems. Or, moreover, in order to conform to various socket specifications having different hole positions, disassembling the power adapter to adjust the electrical pin group is often to be necessary, and thereby causing inconvenience in operation and use.
More particularly, the power adapter, being a conductive device, may cause safety concerns in the case of incorrect operation or collision deformation.
Therefore, the pre sent invention is directed to solve the aforementioned deficiencies.
