Abstract: 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.

Abstract: The chip of an invention for an electronic circuit card comprises a semiconductor microplate having an active face provided with contact pads and on which projections are formed of different heights. The active face of the microplate is coated, at least in part, in a layer of insulating material having a thickness that is greater than or equal to the height of the highest projection, said layer being shaped so as to give free access to the contact pads and having an outer face parallel to the periphery of the active face of the microplate. The layer enables the chip to be implanted in a card body while remaining accurately parallel thereto, which is essential to enable conductive tracks to be made subsequently by silk-screen printing.
