Abstract

La présente invention concerne un accessoire d'alimentation électrique qui comprend un boîtier de dispositif (12) et un réceptacle de connexion de fil intégré dans le boîtier du dispositif (12). Le réceptacle de connexion de fil possède deux formations de réception de fil (16.1.1 - 16.1.3) ou plus choisies parmi tout ensemble de deux ou plus parmi une formation de réception de fil de terre, une formation de réception de fil de neutre et une formation de réception de fil de phase, chaque formation de réception de fil (16.1.1 - 16.1.3) possédant un dispositif de retenue de fil destiné à fixer un fil dans le réceptacle, chaque formation de réception de fil (16.1.1 - 16.1.3) étant marquée en fonction du type de fil qu'elle peut accueillir. L'accessoire d'alimentation électrique comprend également un contact électrique dans chaque formation de réception de fil (16.1.1 - 16.1.3), chaque contact électrique étant relié à un conducteur électrique (14.1 - 14.3) qui s'étend depuis le réceptacle de connexion de fil de telle sorte que lorsqu'un fil est accueilli à l'intérieur de la formation de réception de fil (16.1.1 - 16.1.3), le fil est connecté électriquement au conducteur électrique (14.1 - 14.3).
