Abstract

L'invention concerne une douille de sécurité qui comprend une fixation à baïonnette et une fixation filetée. La première fixation comporte deux tiges métalliques, une coquille, une base, une première et une deuxième lame ressort, une plaque de base et deux ressorts. Dans chaque cas, la tige métallique est montée dans une gaine verticale, la tête de la tige s'étend à l'extérieur de la gaine verticale, la partie barre de la tige s'étend vers le bas, à travers le trou de la plaque de base, le ressort est monté autour de la tige, et ledit ressort est situé entre la plaque de base et la collerette de la tige métallique. Cette dernière comprend une coquille, trois lames ressort de contact qui sont fixées sur la face inférieure de la base, une douille de garniture filetée intérieure et une tige métallique de contact. Un dispositif de retrait peut faire déplacer à la fois la tige métallique par rapport à la troisième lame ressort et la première lame ressort de contact par rapport à la deuxième lame ressort de contact. Lorsque l'ampoule est montée dans ladite douille, sa partie supérieure est poussée vers le bas pour être mise en contact avec la troisième lame ressort de contact et former le circuit galvanique, et ainsi faire fonctionner la lampe normalement. Lorsqu'aucune ampoule n'est montée, la partie inférieure de la tige métallique est séparée de la troisième lame ressort de façon à remplir les exigences de sécurité de non-mise en contact électrique.
