| 摘要 |
The invention relates to a device (1) for accumulation of electrical energy comprising a substantially cylindrical winding of strips (2, 4) at least one strip (2) of which being a strip conductor (2) of electricity, this device (1) being defined transversally by a substantially cylindrical lateral face (1A) and longitudinally by two opposite end faces (1B, 1C) which each contain an edge (2B, 2C) of the said strip conductor (2) of electricity, this device being characterized in that at least one of the edges (2B, 2C) of at least one strip conductor (2) of electricity contains a plurality of teeth (5) disposed in such a way that on at least one of the end faces (1B, 1C) of the device (1) 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 (1A) of the said device, in such a way as to constitute a group of elements of electrical connection to a terminal (6) and in which each element (5) extends itself in continuity with the strip conductor (2) of electricity which comprises it.
