Abstract

L'invention porte sur un adaptateur à fiche et prise qui est muni d’une partie fiche utilisée en tant qu'entrée de puissance et d’une partie prise utilisée en tant que sortie de puissance. La partie fiche est munie de quatre fiches mobiles (6, 7, 8, 9) de différentes normes, qui sont distribuées dans la forme en croix de l'adaptateur. Les fiches sont mutuellement limitées dans leur déplacement par deux tiges de coulissement (13, 14) au niveau de leur partie interne, de sorte qu'il est impossible que plus d'une seule fiche se déplace pour se déployer simultanément. Les fiches de différentes normes peuvent être insérées séparément dans des connecteurs femelles (31, 32) de la partie prise de façon à obtenir une connexion à commutation entre des fiches d'appareil électrique de différentes normes et des prises d'alimentation, résolvant ainsi le problème de correspondance de fiches d'appareil électrique de différentes normes et de prises d'alimentation.
