Abstract

L'invention concerne un ensemble fiche perfectionné permettant de fournir de l'énergie électrique à un dispositif, à partir de plusieurs sources d'alimentation présentant différentes géométries de prises de courant. Selon un premier mode de réalisation, une première et une seconde fiches mobiles, pivotantes, sont placées dans un logement, chaque fiche possédant un contact électrique conçu pour se déplacer et entrer en contact avec les premier et second contacts respectifs d'un dispositif, et un mécanisme de commande qui permet qu'une seule fiche à la fois vienne en contact par pivotement avec un contact correspondant, ce qui permet qu'une seule fiche à la fois laisse passer le courant électrique. Le mécanisme de commande comprend une première et une seconde cames fixées respectivement à la première et à la seconde fiches, et un galet suiveur placé par coulissement entre les deux fiches. Les première et seconde fiches comprennent un connecteur de type EU/européen et un connecteur de type RU, une fiche deux broches, une fiche trois broches, deux fiches polarisées, ou tout autre type de connecteurs ou de fiches permettant de répondre aux besoins d'enfichage d'un utilisateur. L'ensemble fiche double peut être fixé à une combinaison de chargeur et de source d'alimentation pour un dispositif alimenté électriquement pourvu d'une batterie d'alimentation mobile, et peut être utilisé avec le cordon d'extension ou directement avec le cordon d'alimentation dudit dispositif. L'ensemble peut comprendre un panneau pivotant sur un boîtier supérieur qui porte un connecteur extérieur auquel on peut fixer un téléphone mobile. Selon un mode de réalisation, l'ensemble peut comprendre un cordon électrique enroulé sur un organe d'enroulement. Selon un autre mode de réalisation, l'ensemble peut comprendre une ou plusieurs prises de courant femelle destinées à recevoir des connecteurs de géométrie variable.
