Definitions

  • the invention concerns electric safety sockets for civil and industrial installations.
  • Subject of the invention is a safety socket the contact points of which connect with mains electricity by closure of an integrated electro-electronic circuit set up inside the socket itself.
  • the integrated electric-electronic circuit comprises an actuator connected to a control logic and driver fed by the low voltage of mains electricity, in turn connected to a pair of relay switches, one for each phase of the electric current. Closure of the integrated circuit, and therefore connection between the socket contacts and main electricity supply, is obtained, after the pins of the plug or adapter have been completely inserted into the socket, by the elements of said plug or of said adapter operating on said actuator.
  • One type of actuator closes the integrated circuit by means of a reed bulb.
  • the operating elements of said plug and of said adaptor consist of a pair of permanent magnets placed close to the pins of the plug or of the adapter.
  • One type of actuator comprises a micro switch worked by the operating elements of the plug or of the adapter when their pins have been pressed right into the socket.
  • One type of actuator comprises an optic sensor that closes an integrated circuit, the operative element of the plug or of the adapter being an emitter of light. Emission of light in the plug is obtained by a Light Emitting Diode, or LED. Closure of the integrated electro-electronic circuit takes place later, when insertion of the pins of the plug or of the adapter has been completed and therefore connection of the contacts in the socket to mains electric current, after the pins of the plug or of the adapter have matched up with the socket contacts, so making it impossible for an electric arc to form. Feed is preferably by capacitive drop, supplying an output of 10 Volts with a current maximum of 10 mA.
  • the relays present coils of 110 V if connection is in series, or of 220 V if in parallel.
  • the invention offers evident advantages.
  • the sockets subject of the invention offer complete safety as, even if thin conducting objects are inserted into their holes, no connection with mains current is made.
  • plugs other than the Italian type being used such as the "shuko" for example, small alterations are made to the plugs and adapters.

Abstract

La présente invention a trait à une prise de sécurité dont les contacts sont connectés au courant à partir du réseau de distribution électrique par la fermeture d'un circuit intégré electro-électronique installé à l'intérieur de la prise et comportant un actionneur connecté à une commande logique et un circuit de commande, alimenté par un courant de secteur à une très faible tension, ladite commande logique et le circuit de commande étant à leur tour connectés à des paires de contacteurs-relais, un pour chaque phase du courant électrique, la fermeture du circuit intégré étant obtenue par l'insertion totale dans ladite prise des broches d'une fiche ou d'un adaptateur, notamment des connecteurs électromécaniques au courant électrique de secteur et à un point quelconque d'utilisation.
