TRIPHASIC PLUG WITH INTERLOCKING SYSTEM

摘要

The triphasic plug with interlocking system that connects the electric consumers to high power installations consists mainly of a socket that is connected to a plug and a double-throw single-pole switch on whose driving axle there is a profiled area through a square orifice, equipped with a guiding channel and an edge whose height linearly varies from zero to the maximum value. This edge determines the position of a retention lever, which can revolve in pivoting motion, so that, when the double-throw single-pole switch is in "connected" mode, a fold of the retention lever goes through a circular channel of the plug, stopping it from unplugging.
