Summary:The invention relates to a corona igniter comprising a central electrode (7); an insulator (6) in which the central electrode (7) is plugged; a coil (5) which is connected to the central electrode (7); and a housing (4) in which the coil (5) is arranged. The housing (4) is closed by the insulator (6) at one end and has an HF plug connector at the other end, said HF plug connector having an inner conductor (2) which is connected to the coil (5) and an outer conductor (2) which is connected to the housing (4). According to the invention, the HF plug connector contains a glass body (3) which seals an annular gap between the inner conductor (2) and the outer conductor (1). The invention further relates to an HF plug connector suitable for such an HF igniter. L'invention concerne un système d'allumage à effet corona, comprenant une électrode centrale (7), un isolateur (6) dans lequel l'électrode centrale (7) est insérée, une bobine (5) reliée à l'électrode centrale (7), et un boîtier (4) dans lequel la bobine (5) est disposée. Le boîtier (4) est fermé à une extrémité de l'isolateur (6) et, à l'autre extrémité, il porte un connecteur HF qui comprend un conducteur intérieur (2) connecté à la bobine (5) et un conducteur extérieur (1) connecté au boîtier (4). Selon l'invention, le connecteur HF contient un corps en verre (3) qui obture une fente annulaire entre le conducteur intérieur (2) et le conducteur extérieur (1). L'invention concerne en outre un connecteur HF adapté pour être utilisé dans un tel système d'allumage HF.
