An exemplary electrical connector assembly includes a power plug and a power socket. The power plug includes a magnet. The power socket includes a pop-up mechanism. The pop-up mechanism includes a sliding assembly which can be switched from a first position to a second position. When the sliding assembly is switched from the first position to the second position, the pop-up mechanism generates a magnetic field which repels the magnet of the power plug, and the power plug moves away from the power socket.
