Patent attributes
A three-phase electrical connection system includes a socket, a plug, and a two-part magnetic indexing device with two parts, one being fastened to the socket and the other being integral with the plug. Both parts have an annular yoke and a magnet set comprising three permanent magnets. The yoke comprises ferromagnetic material, an axis of revolution, and at least one revolution support face formed in a plane transverse to the axis of revolution. The face is divided into three distinct annular portions, each of which extends one-hundred and twenty degrees of arc. The three magnets are attached to a distinct annular portion of the yoke and are spaced from one another by a first non-zero angular interval. The magnets all have the same magnetic orientation parallel to the axis of revolution. The magnets of the two part are attracted to each other.
