Abstract: An ignition coil, in particular for an internal combustion engine of a motor vehicle, having a secondary winding situated on a coil body for the production of a high voltage at a spark plug, having a contact sleeve that electrically contacts the secondary winding and that is capable of being pushed over an end area of the coil body and that has at least one contact element for the secondary winding, and having a holding-down element that can be pushed over the contact sleeve and that acts on the at least one contact element of the contact sleeve. In its end position, the holding-down element protrudes beyond the at least one contact element of the contact sleeve, seen in the axial direction of the coil body, and covers the at least one contact element.

Abstract: A magnetic circuit for an ignition coil or a transformer, including an inner, essentially rod-shaped core and an outer core. The outer core includes a strip-shaped element of thickness, length and width, and is situated around the inner core in such a way that the strip-shaped element is positioned at the faces of the inner core with its thickness perpendicular to the longitudinal direction of the inner core.

Abstract: An electrical connection set-up for connecting thin enameled wires in ignition coils, which is to replace thermal methods, for example. This is achieved in that, to produce contacting between the winding and the respective high-voltage or low-voltage outlets, an individual contact element able to be slid over the winding by its one side and is fixed in place via its other side, the contact element having a spring-type design, a sliding surface, and at least on its one side fans out in a tulip-shape in the sliding direction, in such a way that the contact element presses against the winding in a spring-like manner in the mounted state and the insulation layer is ruptured and electrical contacting takes place.

Abstract: An electrical connection set-up for manufacturing an ignition coil is provided, which includes, on the side of the low-voltage outlet, a contact spring which is installed by being lifted over corresponding secondary windings without touching them and which then snaps into place due to spring-like form or support, while elements provided on the contact spring break through an insulating layer surrounding the secondary winding, thus establishing the electrical connection without the use of thermal methods.

Abstract: An electrical connection set-up for manufacturing an ignition coil is provided, e.g., for connecting thin enameled wires in ignition coils. In this regard, on the side of the high-voltage outlet, a contacting sleeve is provided which is installed by being lifted over a corresponding secondary winding without making contact and which then snaps into place due to the spring-like form or mounting, while elements provided on the contacting sleeve break through an insulating layer surrounding the secondary winding, thus establishing the electrical connection without the use of thermal methods.
