A system and method for ensuring a defined position of a charging connector includes a signal transmitter, a corresponding signal detector unit for detecting the signal of the signal transmitter, and a holder for holding the charging connector in the defined position. A detector device detects an orientation and/or movement of the charging connector in an environmental coordinate system. The system detects a presence of the charging connector in the defined position and determines the mechanical condition of the interface or a housing of the charging connector via the signal of the signal transmitter, and compares the orientation and/or movement of the charging connector with a corresponding orientation and/or movement of the charging connector to be expected when the charging connector is in the defined position.
