Abstract:
1. A plug assembly, comprising: a power plug comprising a first housing defining at least two slots extending along a first direction, a rotating plug assembly, two conductive connecting blades, a transmission mechanism, and a locking mechanism comprising two locking blocks, the conductive connecting blades fixed to an inserting portion of the first housing, the rotating plug assembly comprising at least two plug pins adapted to connect with a socket of an external power source and configured to be rotatably fixed in the first housing to make the rotating plug assembly connect with the conductive connecting blades or disconnect with the conductive connecting blades, such that the rotating plug assembly changeable between a retracted state and a protruding state, the two locking blocks received in the first housing and configured to move closer or further away from each other along a second direction perpendicular to the first direction, and the transmission mechanism received in the first housing and configured to move up and down along a third direction perpendicular to the first and second directions; and an accepting assembly comprising two conductive poles structured and arranged to be electrically connected to circuit elements of a desired electrical device, a charger cover, and a buckling mechanism received in the charger cover, the buckling mechanism comprising a buckling block configured to move up and down along the third direction, the two conductive poles fixed to an accepting portion of the charger cover which detachably engaged with the inserting portion and allows the inserting portion to be inserted into the accepting portion to make the conductive connecting blades electrically connect with the conductive poles; wherein in the protruding state, the rotating plug assembly connects with the conductive connecting blades such that the operation voltage of the external power source is applied to the circuit elements of the electrical device, the rotating plug assembly drives the transmission mechanism to move down to insert into the charger cover, drives the buckling block to move up to insert into the first housing, and drives the locking blocks move closer and lock with the buckling block; and in the retracted state, the rotating plug assembly disconnects with the conductive connecting blades, the rotating plug assembly drives the transmission mechanism move up, drives the locking blocks to move further away from each other, such that the locking blocks release the buckling block.
