Abstract (en)
[origin: WO2004042748A1] The invention relates to a connection arrangement for the production of an ignition coil which should replace current contacting methods for connecting thin enameled wires in ignition coils, for example, thermal methods. According to the invention, a contact bushing (26) is provided on the side of the high voltage output (H), which are raised in a contactless manner over a corresponding secondary winding for assembly and then snapped as a result of the springlike configuration or mounting. Thus, the elements which are provided in the contact bushing (26) pierce an insulating layer surrounding the secondary winding, thereby producing an electrical connection without having to use thermal methods.
