Description

The innovation is based on a line transformer with a winding made of a metallic foil and a plastic foil in between serving as insulation, the winding taps from transversely to Winding inserted or welded onto the metal foil protruding beyond the foil edges electrically conductive molded parts.

For simplification and cheapening of -Production of a package for a line transformer, it is known to produce rit Hi i * "= a metallic foil to the winding, where: si η electrical as insulation a · ■ ^'1 J r ε t stoffcliensinlage serves the individual.

There are so-called diode-split line transfor- mation formats known, which consist of a first winding that the Primary winding and the secondary windings carries and diE have a second winding from which the high voltage is taken. The high voltage winding consists of several winding chambers into which the high-voltage winding is distributed · The individual winding sections in the chambers are connected in series via diodes · The high-voltage winding is in one Resin embedded to achieve sufficient High voltage resistance. There is one sufficient large coupling between the coils necessary, d. H. the winding space is in such transformers very limited for the first mentioned lap. Since the Primary winding of the first winding has a relatively high number of turns, this primary winding takes in Foil technology takes up too much changing space.

Task and solution

The renewal is therefore based on the task of a winding technology that is as space-saving as possible for one Find Diode Split Transformer. This task is solved by the measure specified in the identifier of the protection claim.

The innovation in an exemplary embodiment will be explained in more detail below with the aid of the drawing

1 with the winding body of the first winding is referred to, on which in known winding technology
the secondary winding, consisting of metal foils
2 and insulating intermediate layers 3 is arranged.
At those points of the winding at which taps are led out, mstallic molded parts 4 are welded transversely to the direction of the film, the ends of which protrude beyond the edges of the film. To this
Foil winding is a primary winding, consisting
wound from copper wire turns 5. About this
Winding, the winding body 6 for the high-voltage winding can be pushed. According to the innovation is now
for the purpose of returning ¹ "of the wire end 11 egg winding 5 .ein molded part 7 in xner insulating film layer B,
embedded between the two windings 3 and 5, inserted, which protrudes at both head ends of the winding. The portion of the molded part 7 opposite the connection side 9 is connected to the wire end 10 of the winding 5, so that both ends 9, 10
this winding lie on a side common to the other connections. In this way there is a simple return that is not bulky and
thus saves space, since an additional molded part included in the coil does not increase the diameter of a coil such as, for example, a return of the wire end outside the coil.
