Definitions

  • the invention relates to signaling and / or lighting devices for motor vehicles.
  • a signaling light comprising a socket and a lamp adapted to be introduced into the socket to an installation position.
  • the lamp base has bayonets adapted to be engaged in notches of the socket in order to lock the lamp in the mounting position.
  • a transparent glass is sealed on the light housing opposite the lamp. It was found that the lamp could be mounted in the socket without reaching the locking position, the lamp being only immobilized in the socket by jamming.
  • Such an assembly is precarious and the lamp can easily separate from the socket, for example under the effect of the vibrations generated by the rolling of the vehicle. The lamp then falls into the housing and remains trapped there. The same problem can occur on the assembly line after the glass has been sealed, resulting in the scrapping of the fire.
  • Document EP-0 637 859 describes a socket and lamp assembly for this type of motor vehicle, the lamp being adapted to be inserted into the socket to an installation position, the device comprising means for locking the lamp in mounting position, the socket comprising a flexible blade partially in the direction of insertion of the lamp, the blade being arranged to come into contact with the lamp before the lamp arrives in the mounting position.
  • An object of the present invention is to avoid fixing the lamp to the socket in a position different from the intended mounting position.
  • a signaling and / or lighting device for a motor vehicle comprising at least one socket and at least one lamp suitable for being inserted into the socket up to a mounting position, the device comprising means for locking the lamp in the mounting position, the socket comprising a flexible blade at least partially in the direction of insertion of the lamp, the blade being arranged to come into contact with the front lamp the arrival of the lamp in the mounting position, in which the blade has sufficient stiffness to eject the lamp out of the socket when the lamp is not locked.
  • the flexible blade biases the lamp in the direction opposite to its direction of introduction into the socket and the lamp is ejected from the socket. This avoids fixing the lamp to the socket in a position different from the intended mounting position.
  • the device in FIG. 1 is a signaling light for a motor vehicle. It comprises a lamp holder 2 comprising a socket 4 having a cylindrical wall with axis 5 and a bottom. It also includes a lamp 6 adapted to be introduced in translation along the axis 5 in the socket to a mounting position corresponding to the end of the lamp stroke in the socket.
  • the lamp has lateral bayonets 8.
  • the socket has notches 10 in the shape of an "L" reversed in the figure.
  • the large branch of the "L” is parallel to the axis 5 and opens at the open end of the socket.
  • the small branch of the "L” forms a 90 ° elbow with the small, and extends perpendicular to the axis 5, about halfway from the bottom and free end.
  • the introduction of the lamp base into the socket is effected by engaging the bayonets in translation along axis 5 in the respective notches, then after crossing the elbow by rotating the lamp a portion of a turn around the axis 5 to arrange the bayonets at the bottom of the notches.
  • the bayonets and the notches thus cooperate with each other to constitute means for locking the lamp in the mounting position in the socket.
  • the socket includes a flexible metal blade 12a, 12b arranged to come into contact with the lamp before the lamp arrives in the end-of-travel mounting position.
  • the blade 12a is adjacent to the bottom of the socket and is flexible in the direction of insertion of the lamp, namely along the axis 5.
  • the blade is fixed by a first end to the bottom of the socket and comes into contact with the lamp in the vicinity of a second end not parallel to the axis 5. Between these two ends, the blade has two successive opposite curvatures.
  • the blade has sufficient stiffness to eject the lamp from the socket when the lamp is not locked, that is to say when the lamp is inserted into the socket in the vicinity of the mounting position, without being locked.
  • This blade is an electrical connection blade of the lamp, intended to be connected to earth.
  • the blade 12b is adjacent to the side wall of the socket.
  • the blade is substantially rectilinear and inclined relative to the direction of introduction, namely the axis 5.
  • the blade is directed towards the bottom of the socket and is fixed to the wall by an end axially opposite the bottom.
  • the blade is partially flexible in the direction of insertion of the lamp.
  • the blade has sufficient stiffness to eject the lamp out of the socket when the lamp is not locked.
  • This blade is an electrical connection blade of the lamp, intended to be connected to a positive or negative terminal of an electrical supply.
  • the device may include or be a lighting projector.
  • the device may include several sockets and several lamps.
