It only takes one person to install any aspect of the product and the supply cables are always safely contained within the ceiling void after installation of the back box 2. The rest of the circuity of the system is inaccessible when the plug 40 is connected to the socket 24. Disconnection of the plug 40 from the socket 24 removes the power supply thereby removing the possibility for electric shock. Both the electrical connection and weight of an electrical device is supported by the system simultaneously. The system is further user friendly, since an electrician can install the back box 2 and the socket 24. The consumer need only then connect the plug 40 to the electrical device at no risk to themselves. The system is further adaptable to facilitate Ethernet over power adapters through lighting circuits, for example.

L'invention concerne un système de branchement électrique destiné à brancher de manière détachable un dispositif électrique à des câbles d'alimentation électrique, comportant une fiche susceptible d'être reliée électriquement à un dispositif électrique et une prise susceptible d'être reliée électriquement à des câbles d'alimentation électrique. La prise est prévue pour assurer une liaison de montage et un branchement électrique avec ladite fiche via des contacts correspondants. La liaison de montage est libérable et permet à la fiche de pouvoir tourner dans ladite prise. Les contacts de la prise et de la fiche sont disposés de telle façon que, lorsque la fiche est montée dans la prise, ils soient reliés électriquement entre eux dans n'importe quelle orientation de la fiche dans la prise. La liaison de montage entre la fiche et la prise comporte des goupilles de positionnement autour d'une périphérie extérieure d'une enveloppe de fiche configurée pour interagir avec une extrémité ouverte de rainures de positionnement de goupilles dans la prise menant à une gouttière de montage. Les goupilles de positionnement peuvent tourner autour de la gouttière.
