TECHNICAL FIELD

The present invention relates to a power adapter; specifically, it particularly relates to a power adapter which has reduced internal space.


BACKGROUND ART

Nowadays, with the rapid development of science and technology, more and more miniaturized electronic devices have been developed, and power adapters are indispensable parts to many electronic devices.


At present, the power inlet sockets of the power adapters are mostly independent structures. More specifically, the power adapter needs an assembly structure to fix the power inlet socket to a housing of the power adapter, such as a card slot. Moreover, since the strength of the power adapter is required to be high, more auxiliary elements in the assembly structure is needed to meet the safety requirement. That is to say, the power adapter needs be designed to have more space in order to meet the safety requirement, and it goes against product miniaturization. Therefore, it is necessary to develop a power adapter which does not have the above-mentioned defects.
