Abstract
A socket for an electric light is provided including a first electric supply circuit, a second electric supply circuit, and a safety device adapted to detect presence or absence of a light bulb in the socket.
Claims35
A socket for an electric light bulb comprising:
- a first electric supply circuit supplying a phase voltage and including at least a first contact block provided at a bottom of the socket and a first contact piece;
- a second electric supply circuit supplying a neutral voltage including at least a fixing tube having at least one conductive portion fitted into an insulating support and a second contact piece;
- a safety device adapted to detect a presence or absence of a light bulb in said socket, the safety device including a disc made of an insulating material and provided with a plurality of radial extensions;
- said disc being fitted into said socket so that the plan of said disc is essentially perpendicular to the longitudinal axis of the socket, said disc being adapted to slide along a direction of said longitudinal axis of the socket, being pushed by an elastic member to move away from the bottom of the socket, said radial extensions being adapted to slide into recesses provided within the socket in order to guide said disc, an abutment being provided in at least one recess to restrict the sliding of the disc towards the exterior of the socket;
- and
- said disc further including at least one conductive capsule traversing the disc and adapted to establish an electric contact between the first contact block and a cap bottom contact of the light bulb when the disc is pushed against the bottom of the socket by said light bulb fitted into the socket,
- wherein said disc further includes a conductive pathway insulated from the conductive capsule and provided on a face of said disc facing the bottom of the socket;
- and
- wherein said bottom of the socket further including two further contact blocks each provided opposite a portion of said conductive pathway, a first of said further contact blocks being electrically connected to the conductive portion of the support tube.

- and
- said disc further comprising at least one conductive capsule traversing the disc and adapted to establish an electric contact between the first contact block and a cap bottom contact of the light bulb when the disc is pushed against the bottom of the socket by said light bulb fitted into the socket;
- wherein the socket further includes:
- an additional safety device including an insulated actuating device having a first extremity protruding in the interior of the socket and a second extremity provided within a recess of the insulating support and provided with a first contact capsule;
- a second contact capsule being disposed into said recess opposite said first contact capsule;
- an elastic member being provided to separate the contact capsules one from the other;
- the fitting of a cap of a light bulb into the socket actuating said insulated actuating means, thus putting into contact the two said contact capsules, a first of said capsules being electrically connected to the conductive portion of the support tube while the second of said capsules being electrically connected to the second contact piece.
