Definitions

  • the present invention belongs to the field of electricity, and relates in particular to a socket for an electric bulb.
  • the invention also relates to an electrical assembly provided with such a socket and a bulb mounted in this socket, as well as a method of assembling such an electrical assembly.
  • Light bulb sockets are well known. They conventionally comprise a receiving structure configured to receive a base of a bulb and provided with electrical contact tabs to electrically supply the bulb.
  • Such electrical contact lugs are generally accessible from an opening in the receiving structure through which the base of the bulb is introduced. There may be a risk of electrification or even electrocution by the electrical contact tabs of the socket.
  • light bulb sockets are configured to allow current to flow through the electrical contact tabs only when a light bulb is mounted in the socket.
  • a light bulb socket including a protection mechanism.
  • the protection mechanism comprises a receiving structure defining an internal space for receiving a base of an electric bulb and an interface device movably mounted in said internal space between a safety position and a power supply position.
  • the interface device comprises electrical contact lugs which open into the receiving housing and which are configured to cooperate with the base and a stud of the bulb.
  • the interface device also includes connection pads connected to an electrical power source.
  • the protection mechanism further comprises a stationary plate provided with two conductive parts.
  • the protection mechanism described in the document US 2009/0269961 is configured to assume a secure configuration in which the interface device is in the secure position and the connection pads are remote from the conductive parts of the stationary plate, and a connected configuration in which the interface device is in the power supply position and the connection pads are in contact with the conductive parts of the stationary plate.
  • the protection mechanism switches from the secure configuration to the connected configuration by screwing the bulb to the interface device, which causes the interface device to move towards the stationary plate until the latter is brought into contact with the connection pads, and from the configuration connected to the configuration secured by unscrewing the bulb.
  • the present invention aims to provide a socket for an electric bulb of a similar type, provided with a protection mechanism allowing the passage of electric current only when a bulb is mounted in the socket.
  • the protection mechanism changes from the secure configuration to the connected configuration by mounting the light bulb with the interface device, and from the connected configuration to the secure configuration by removing the light bulb.
  • the tracks are configured to be connected to an electrical power source
  • the connection pads are each electrically connected to one of the electrical contact tabs of the interface device
  • the electrical socket is configured so that said connection pads slide on the tracks between the conduction and interruption positions at the same time as the body is moved between its security power supply positions when the protection mechanism changes from the secure configuration to the connected configuration and vice versa, with the pads which are in contact with the non-conductive portions of the tracks in the interrupt position.
  • the electrical socket thus proposed allows the passage of current only when an electric bulb is mounted with the socket. Mounting the light bulb causes the protection mechanism to switch to the connected configuration. Dismantling the light bulb causes the protection mechanism to switch to secure configuration.
  • the electrical socket is secure since only cooperation with an electric bulb allows the passage of electrical current in the electrical contact tabs.
  • the receiving structure comprises a bearing edge delimiting the introduction opening, and the interface device passes from the safety position to the supply position under the effect of the cooperation of a shoulder of the base of the light bulb with the supporting edge of the receiving structure.
  • the housing for receiving the interface device comprises on an internal surface a female thread provided for mounting by screwing the base of the electric bulb
  • the tracks extend longitudinally in the receiving structure and opposite the connection pads mounted in the body.
  • the protection mechanism further comprises an elastic return member disposed between the body of the interface device and an internal edge of the receiving structure, said elastic return member being configured to return said body from its supply position to its position after removing the light bulb from the interface device.
  • the protection mechanism further comprises abutment members configured to stop the interface device in the safety position when removing the light bulb from the interface device.
  • the body of the interface device is further provided with power supply terminals configured to be connected to the external power supply source, each track being connected to one of said power supply terminals housed in the body.
  • the electrical socket further comprises a cover fixed to the receiving structure opposite the insertion opening, said cover comprising at least one orifice for the passage of conductive wires coming from the external electrical power source.
  • the receiving structure comprises a window exposing a part of the body of the interface device, said body comprising two different markings, the window and the markings being arranged so that when the protection mechanism is in the secure configuration, the window is facing vis-à-vis a first of said markings, and when the protection mechanism is in the connected configuration, the window is vis-à-vis a second of said markings.

  • the double movement is practical for example as a child safety device.

  • the socket configuration is advantageous in that it requires no modification of the light bulb, and is suitable for commercially available bulbs.
  • the electrical socket described is particularly suitable for E14 and E27 screw bulbs.
  • the configuration of the socket according to the invention also aims to enable it to achieve a protection index as defined by the international standard IEC 60529 that is as attractive as possible, in particular an IP 40 index (protection against tools and small wires longer than one millimeter), or even an IP 60 rating (protection against total dust infiltration).
  • a protection index as defined by the international standard IEC 60529 that is as attractive as possible, in particular an IP 40 index (protection against tools and small wires longer than one millimeter), or even an IP 60 rating (protection against total dust infiltration).
