Definitions

  • the object of this invention is an accident-proof bulb-holder.
  • Danger also additionally derives when a bulb-holder is without a bulb, in that a child or even accidentally an adult, could insert a finger into the bulb-holder with danger of receiving an electric shock.
  • the negative mass contact is normally detached from the respective mass conductor and only after elastic pressure said contact is established.
  • a gasket with insulating tongue in elastic plastic material that protracts reducing the opening of the bulb-holder and that with the bulb screwed-in adheres annularly on the edge of the bulb preventing any kind of access to the conductive screwing junction between bulb tang and bulb-holder.
  • the inside of the bulb-holder there is a mobile base that detaches both contacts with the respective conductors.
  • an arm system elastically orientated towards the axis of the bulb tang receiving hole, and thickened to reduce the diameter of the recess and that hooks elastically to the mobile base preventing the lowering, this in such a way that the unhooking of said mobile base, to allow its lowering, can only happen if the tang of the respective bulb is screwed-in.
  • the safety of the system is total because once the bulb is extracted there is no access to the electric current, not even with tools, utensils or various objects.
  • the system operates automatically because the same bulb excludes safety when being screwed.
  • the installation system and use of the bulb-holder does not require any variation in respect to a traditional bulb-holder.
  • the bulb may be of any traditional type with conductor tang mass 1 and axial tang base contact for the tension filament 11.
  • the bulb-holder 2 may be structured externally like all normal bulb-holders, with insulating shell, which upper edge involves an annular gasket in elastic plastic material with tongue that gives 21 that obstructs the mouth of the bulb-holder and when the bulb is inserted it perfectly and hermetically closes the annular access zone to the conductive part.
  • the contacts to the bulb tang protract in an elastic way respectively 23 and 22.
  • Contacts are on an elastically mobile base 24 with a single helical spring 239-229 that pushes it away from the network connection.
  • the underlying contact of axial tension 26 is furthermore elasticized 260.
  • the mobile base as in the preceding solution protracts with radial arms elastically yielding 241 that scroll within a containment bush 243 and the upper extremities of which increase 242 protruding and tightening the mouth.
  • the unhooking only happens if all the thickenings of the elastic arms are pushed outwardly, determining the unhooking of the base to allow the connection with the network.
