Abstract (en)

[origin: EP1732187A1] The radio-frequency plasma plug, containing an inner winding (2) of an electrical conductor wire that forms the inductive part of a high-tension resonator, moulded in an insulating material, has the winding in the form of a bare wire (11) wound on the threaded surface (10) of an insulating mandrel (9) in non-contacting coils. The wire is laid in the thread recesses, which are curved in shape and have a radius of curvature greater than that of the wire.
