An electrical connection configuration, e.g., for an ignition coil, includes: an enameled wire sheathed in insulating enamel, and a contact element for the electrical contacting of the enameled wire, the contact element having a contact region for the electrical contacting of the enameled wire. The contact region has at least one sharp edge, and the enameled wire is routed along the sharp edge, such that a region of the enameled wire stripped of the enamel is provided, which rests against the contact region of the contact element for the electrical contacting.

Electrical connection configuration for an ignition coil

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.

Electrical contacting of thin enameled wires of secondary windings of ignition coils having a contact crown and contact element

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.

Electrical contact between thin varnished wires of the secondary winding of an ignition coil

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.
