Abstract:
A device for accumulating electrical energy comprising a substantially cylindrical winding of strips at least one of which is an electrical strip conductor, this device being defined transversally by a substantially cylindrical lateral face and longitudinally by two opposite end faces which each contain an edge of the electrical strip conductor, this device being characterized in that at least one of the edges of at least one electrical strip conductor includes a plurality of teeth disposed in such a way that on at least one of the end faces of the device they form at least one set in which they are substantially superimposed in a predetermined direction, approximately perpendicular to a plane tangent to the cylindrical face of the device, in such a way as to constitute a group of elements of electrical connection to a terminal and in which each element extends in continuity with the electrical strip conductor which comprises the element.
