Abstract (en)

[origin: WO2009015745A1] An inductive plug-type connection transformer comprises - a ferrite core (3) with an axial length d1, - a primary coil (1) resting on the ferrite core (3) with an axial winding length d2, - a secondary coil (11) with an axial winding length d3, into which the ferrite core primary coil unit (1, 3) can be pushed radially symmetrically and axially into a transmission desired position (P1), in which the ferrite core (3) protrudes axially with its free end (4) plugged through the secondary coil (11) beyond said secondary coil (11), - a position of the ferrite core which is axially symmetrical with respect to the secondary winding, - staggered axial lengths of ferrite core (3), primary coil (1) and secondary coil (11) in accordance with the relationship d1 > d3 > d2, - positioning of the primary coil (1) on the ferrite core (3) which is shifted asymmetrically axially in the direction of the free end (4) of said ferrite core (3), and - positioning of the primary coil (1) in the transmission desired position (P1) within the secondary coil (11) in such a way that the primary coil (1) protrudes axially beyond the secondary coil (11) by an excess distance of d4 < d2 over part of its length.
