Abstract (en)
[origin: EP0485341A1] The small transformer contains a laminated iron core (2) and primary and secondary windings (3, 4) which are held by a coil former (5). The coil parts which project over the iron core (2) are covered on both sides in each case by one cover (6, 7) consisting of plastic. These two covers (6, 7) are connected to one another in one piece by means of first and second webs (12, 14). The first webs (12) fill the cavities between the coils (3, 4) and the iron core (2), and the second webs (14) hold the laminated stack of the iron core (2) intrinsically together. As a result of this construction, particularly economical batch production is possible, it being possible to conform reliably to the electrical safety distances. <IMAGE>
