CORONA IGNITION DEVICE AND METHOD FOR PRODUCING A CORONA IGNITION DEVICE

摘要

The invention relates to a corona ignition device, comprising a center electrode, an insulator surrounding the center electrode, a coil, which is connected to the center electrode, and a housing pipe, in which the coil is arranged. The housing pipe comprises a substrate layer and a conducting layer arranged radially inwardly of the substrate layer. The conducting layer is made of a material having a greater electrical conductivity than the material of the substrate layer. The conducting layer has a thickness of at least 0.1 mm. Also disclosed is a method for producing a corona ignition device, in which, to produce the housing pipe, an inner pipe is inserted into an outer pipe. The invention also relates to a corona ignition device of which the coil is surrounded by a soft-magnetic shielding.
