Thus, the first pin 231 is electrically connected to the circuit board 14 through the first conductive rod 2211 and the first metal dome 41, and the second pin 232 is electrically connected to the circuit board 14 through the second conductive rod 2221 and the second metal dome 42. For example, the circuit board 14, the first metal dome 41 and the second metal dome 42 may be fixed on the bottom case 112 of the first housing 11.

In some exemplary embodiments, the pin portion of the rotatable power adapter of the embodiments of the present invention may rotate 360 degrees clockwise or counterclockwise, and the damping member disposed on the rotating shaft of the pin portion is matched with the abutting portion disposed in the first housing of the main body portion, so that the pin portion may stay at a plurality of rotating positions, and thus, the rotating position of the pin portion may be adjusted according to the environment of the socket during the use of the rotatable power adapter, thereby avoiding blocking the row jack of the socket or the jack on the wall, and when the rotatable power adapter is matched with the jack on the wall, the rotatable power adapter and the data line connected thereto do not easily hinder the furniture from being placed beside the wall. In addition, the rotatable power adapter of the embodiment of the invention can be thinner in overall thickness.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
