ABSTRACT:
A mini-transformer features an iron or ferrite core (2) and primary and secondary windings (3, 4). Portions of the windings (3, 4) which extend beyond the iron or ferrite core (2) are covered on both sides with a thermoplastic material forming a lid (6, 7). The two lids or end bells (6, 7) are combined into one piece by means of first bars (12), which extend through the hollow spaces (9) between the windings (3, 4) and the iron or ferrite core (2) and fill them, and that the laminated iron or ferrite core (2) is fixed in itself by second bars (14) connecting the two lids (6, 7).
