Patent ID: 7578683

Claim:
A plug, comprising: a housing with a first contact face, a first set of pins for a first type of power point, and a first blocking device, comprising interacting first and second blocking means, in which the first set of pins is slidably accommodated in the housing so as to assume an active or a passive position as desired, the first set of pins in the active position projecting from the first contact face of the housing in such a way that said set of pins can be inserted into the first type of power point, the first blocking means are connected to the first set of pins, the second blocking means are connected to the housing, and the first and second blocking means are movable relative to each other, so that they can assume a blocking position, in which the slidability of the first set of pins is blocked, and an unblocking position, in which the first set of pins is slidable, wherein the first blocking device furthermore comprises a first stopper, which first stopper is movable relative to the first and second blocking means between a stop position, in which the first stopper inhibits the movability of the first and second blocking means relative to each other, and a release position in which the first stopper does not inhibit the movability of the first and second blocking means relative to each other.
