(54) Accident-proof bulb holder


(57) Bulb-holder (2) for a screw-in bulb (1), of the type in which:
  • the tang of the bulb is negative mass conductor and threaded (10) for said screwing within the bulb-holder (2) and
  • the positive tension contact of the bulb (11) is at the central base of said tang (10),
said bulb-holder (2) being equipped with lateral (22) and axial (23) corresponding tension contacts,
characterized in that:
  • at least said axial tension contact of said bulb-holder (23) is normally detached with axial sliding, by means of repulsion spring (239) that maintains the tension contact (230-231) interrupted;
  • the closure of the circuit with continuity of the contact can only happen by pressing on said axial contact (23), with a force normally possible by the screwing of said bulb (1).
