Definitions
- the invention relates to signaling and / or lighting for motor vehicles.
- a traffic light comprising a socket and a lamp suitable for being inserted into the socket to an installation position.
- the base of the lamp has bayonets adapted to be engaged in the notches of the socket in order to lock the lamp in mounting position.
- a transparent glass is sealed on the firebox next to 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 arrangement is insecure and the lamp can easily separate from the socket, for example due to vibrations generated by the rolling of the vehicle. The lamp falls then in the case and remains trapped there. The same problem may arise on the assembly line after the ice has been sealed, which results in disposal fire.
- the document EP-0 637 859 describes an assembly with socket and lamp for a motor vehicle of this type, the lamp being adapted to be inserted into the socket to an installation position, the device comprising means for locking the lamp in the position of mounting, the socket comprising a flexible blade partially following the direction of introduction of the lamp, the blade being arranged to come into contact with the lamp before the lamp arrives in the position of mounting.
- An object of the present invention is to avoid the fixing the lamp to the socket in a position different from the intended mounting position.
- a signaling device and / or lighting for a motor vehicle comprising at least a socket and at least one lamp adapted to be inserted into the socket to a position of mounting, the device comprising means for locking the lamp in the mounting position, the socket with at least one flexible blade partially following the direction of introduction of the lamp, the blade being arranged to come into contact with the lamp before the lamp arrives in the position of mounting, in which the blade has a stiffness sufficient to eject the lamp from the socket when the lamp is not locked.
- the flexible blade biases the lamp in the opposite direction to its direction of insertion into the socket and the lamp is ejected from the socket. This avoids fixing the lampholder in a position different from the intended mounting position.
- an assembly according to claim 4 or claim 6 is also provided.
- the device in Figure 1 is a signaling for motor vehicle. It has a lamp holder 2 comprising a socket 4 having a cylindrical wall with axis 5 and a bottom. It comprises also a lamp 6 adapted to be introduced in translation along axis 5 in the socket to a mounting position corresponding to the end of the the lamp in the socket.
- the lamp has side bayonets 8.
- the socket has notches 10 in the shape of an "L" overturned in the figure.
- the big one branch of "L” is parallel to axis 5 and leads to the open end of the socket.
- the little branch of "L” forms a 90 ° elbow with the small one, and extends perpendicular to axis 5, about halfway down the bottom and free end.
- the introduction of the lamp base in the socket is made by engaging the bayonets in translation along axis 5 in the respective notches, then after crossing the elbow by rotating the lamp of a tower portion around axis 5 for arrange the bayonets at the bottom of the notches.
- the bayonets and notches thus cooperate mutually to constitute means for locking the lamp in mounting position in the socket.
- the socket has a flexible metal blade 12a, 12b arranged to come into contact with the lamp before the lamp arrives in the mounting position at the end race.
- the blade 12a is adjacent to the bottom of the socket and is flexible according to the direction of insertion of the lamp, namely along axis 5.
- the blade is fixed by a first end at the bottom of the socket and comes into contact with the lamp near a second end not parallel to axis 5. Between these two ends, the blade has two successive opposite curvatures.
- the blade has sufficient stiffness to eject the lamp out of 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 a connection blade electric lamp, intended to be earthed.
- the blade 12b is adjacent to the side wall of the socket.
- the blade is substantially straight and inclined with respect to the direction of introduction, namely 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 direction 5 lamp introduction.
- the blade presents sufficient stiffness to eject the lamp out of the socket when the lamp is not locked.
- This blade is a blade for electrical connection of the lamp, intended to be connected to a positive or negative terminal of a power supply.
- the device may include or be a lighting projector.
- the device may include several sockets and several lamps.
