Abstract: A corona discharge device having a coronode of the type including a wire electrode coated with a fractureable dielectric sleeve for example, glass. Electrical contact is made to the wire via a conductive member forcibly attached or crimped to the sleeve to fracture it sufficiently to permit direct contact between the wire and the member.

Abstract: A corona generating device including a coronode in the form of a wire supported between insulating end block assemblies. Each assembly is constructed of mating half-sections which jointly define a substantially closed and insulated cavity lined with a conductive insert. The insert on the high voltage side of the coronode serves to couple electrically the high voltage terminal to the coronode via a first conductive bead carried by the coronode. The coronode is held taut by means of a loaded compression spring carried within the insert on the half-section removed from the high voltage supply, the spring bearing against the conductive insert on one end and against a second conductive bean carried by the other end of the coronode.
