PLUGGABLE ELECTRIC SECURITY CONNECTION

摘要

An electrical safety plug connection in which the part of the power outlet accessible from the outside becomes separated from the source of power when the plug is pulled out. The power outlet has two chambers one above the other, the lower chamber being a self-contained chamber which contains the live contacts and which is separated by an insulating partition from a receiving chamber thereabove which receives the plug. Bridging contacts are arranged in the insulating partition, and the bridging contacts extend from the lower chamber into the receiving chamber. In the closed chamber there is a magnetic body which usually rests on the bottom of the chamber but is freely movable in the upward direction. This magnetic body has connecting elements which connect the contacts to the source of power and the bridging contacts when the magnetic body is in an elevated position, but do not connect them when it is in its lower position, and it is caused to move to its elevated position only when the plug has been inserted in the upper chamber by a magnet carried by the plug.
