Abstract

L'invention porte sur un transformateur d'allumage qui comporte : un enroulement primaire (1) comportant une pluralité de fils conducteurs et de charges de décharge électrique chargées dans un condensateur (34), et un enroulement secondaire (2) comportant un certain nombre de fils conducteurs inférieur au nombre de fils conducteurs de l'enroulement primaire et distribuant, à une ampoule sans mercure (32), des impulsions haute tension générées du fait de la décharge par l'enroulement primaire (1). Grâce à l'enroulement primaire, qui est empilé sur au plus deux couches, et à l'enroulement secondaire (2) qui est côte à côte au niveau de la surface inférieure d'une borne en forme de U (3), à la courbure des deux cotés de l'ouverture en forme de U et à l'exécution d'une fusion, l'enroulement primaire (1) et l'enroulement secondaire (2) sont simultanément connectés électriquement. Ceci permet une connexion électrique fiable des deux enroulements (1, 2) à la borne (3), sans augmenter la dimension de la borne (3), et sans décollement des enroulements.
