When the second charging electrode 401 is energized, the deformation layer 203 is in a grounded state, the conductive layer 202 is in an energized state by a connecting wire, a voltage difference is generated between the deformation layer 203 and the conductive layer 202, the deformation layer 203 expands and deforms, and when a current on the conductive layer 202 disappears, the deformation layer 203 contracts to an initial state. Specifically speaking, when a power plug is inserted into the electric connection interface through the socket, the power plug is electrically connected with the second charging electrode 401, the second charging electrode 401 transmits current to the conductive layer 202, the deformation layer 203 is in a grounded state at this time, and the deformation layer 203 expands due to the pressure difference between the deformation layer 203 and the conductive layer 202, so that the charging plug is clamped and fixed in the shell 100, the charging plug is prevented from falling off in the charging process, and the charging operation can be stably completed.
