Abstract (en)

[origin: EP0907190A2] The windings former, is melted onto the ferromagnetic core (1), through an excess of plastic, and/or the core is fastened to the substrate (2) by melting-on plastic. An Independent claim is included for the method of construction. After placing core, former and winding on the substrate, the flanges projecting over the core are heated, to melt the plastic locally. The softened plastic is pressed onto the surfaces of the core, and allowed to set. Preferably the excess plastic is melted-on by a heated rod. Preferred features: The core is fastened to the thermoplastic substrate by melting-on the plastic flanges (4). There is a projection (5) on the edge of each flange. The projection extends over part of the flange length. The flange is introduced into openings or separate slots of the core.
