Abstract

L'invention concerne un culot d'ampoule électroconducteur amélioré destiné à être utilisé avec des douilles d'ampoule filetées d'usage courant. L'amélioration consiste en une réduction sensible de la quantité requise du filetage, grâce à l'utilisation d'un filetage plus court dont la taille et/ou le rayon augmentent. Ce type de filetage remplace le filetage courant permettant de fixer l'ampoule dans la douille. Eventuellement, des parties courtes de filetage peuvent être disposées sur un côté de la paroi d'un culot généralement cylindrique et lisse. L'avantage particulier réside dans le fait que l'ampoule qui est fixée à la main peut être fixée ou enlevée avec un nombre réduit de rotations de poignet.
