Claim 0:
1. An assembly of an electrical device and a printed circuit board,
the electrical device comprising a terminal region for connection with the printed circuit board, the printed circuit board comprising contacts for electrical connection,
wherein the terminal region consists of a single stranded wire and an enclosure piece, the enclosure piece surrounding the single stranded wire,
wherein the single stranded wire includes a plurality of individual wires, and the individual wires have individual insulations,
wherein the single stranded wire has an outer insulation enclosing all the individual wires, and
wherein the individual insulations are present in regions outside the terminal region and are at least partially removed in the terminal region,
wherein the outer insulation is present in regions outside the terminal region and is at least partially removed in the terminal region,
in which the enclosure piece consists of a metallic band piece, in which the enclosure piece has marginal zones that overlap, wherein the single stranded wire is connected with the enclosure piece by thermal diffusion bonding, wherein the overlapping marginal zones are connected to each other only through thermal diffusion bonding, wherein the electrical device is mounted on the printed circuit board, wherein the terminal region is directly connected with the contacts of the printed circuit board by soldering, and wherein the single stranded wire terminates flush with the enclosure piece or protrudes out of the enclosure piece at both ends;
wherein the electrical device includes a second terminal region, the second terminal region comprising a second end of the single stranded wire and a second enclosure piece, the second enclosure piece surrounding the second end of the single stranded wire, the single stranded wire forms a winding for the device in which a first end of the single stranded wire is at the terminal region and the second end of the single stranded wire is at the second terminal region, the winding being formed by a portion of the single stranded wire between the first end and the second end;
wherein after the single stranded wire is connected to the enclosure piece and the winding is formed around a winding support, the electrical device is mounted on the printed circuit board;
wherein the winding support includes two integral holder elements for holding the single stranded wire adjacent to or at the terminal region and the second terminal region;
wherein each of the two integral holder elements clamps around a portion of a circumference of the single stranded wire.
