Definitions

  • the contact carrier is held at a manufacturing technology simple embodiment of the invention by means of at least one securing element, in particular a securing ring on the projection.
  • This solution has the advantage over screwed solutions that no threads need to be cut in the reflector so that dust does not form. Dust on the surfaces of recycled A-Lectors is very critical.
  • the light source used is preferably a lamp, in particular a halogen incandescent lamp, which can be fixed to the reflector by means of a bayonet closure.
  • the invention can be used, for example, advantageously in single or double helical halogen lamps which are used in motor vehicle headlights.
  • the contact carrier is provided with chamfers, so that this produces no abutting edges, which complicate the insertion of the tabs of the lamp in the socket contacts of the contact carrier.
  • FIG. 1 shows an exploded view of a headlight according to the invention
  • the headlight according to the invention is by no means limited to such headlight types.
  • the reflector 2 has two pin-shaped projections 26, 28 which are for mounting the contact carrier 12 on the reflector 2 in engagement with corresponding recesses 30, 32 of the contact carrier 12 can be brought.
  • the pin-shaped projections 26, 28 extend approximately parallel to the reflector longitudinal axis 22.
  • one of the projections 26 is cylindrical and has a radially recessed contact surface 34 for limiting the installation depth of the contact carrier 12.
  • the contact carrier 12 has a fastening section 36 which is adapted to the cross-section of the contact surface 34 and can be fixed to the cylindrical projection 26 by means of a securing element, for example a securing ring 38.
  • the second projection 28 is provided with a non-circular section designed as a square section 40 and has a radially recessed contact surface 42 for limiting the installation depth of the contact carrier 12.
  • the Baj onettver gleich consists according to Figure 2 essentially of a mounting opening 44, the edge of which is provided with three mutually offset by approximately 120 ° each other recesses 46 for receiving three locking tabs of the lamp 10 (see Figure 1), not shown.
  • the recesses 46 are limited by locking portions 48.
  • the lamp 10 is fixed in the mounting hole 44 by the locking tabs slide on ramps not shown on the locking portions 48. The ramps complicate a rotational movement of the lamp 10 in the direction of rotation and prevent an automatic unlocking of the bayonet lock.
  • the arrangement of the locking tabs of the lamp 10 and the locking portions 48 of the reflector 2 ensure that the contact lugs 6, 8 (see Figure 1) of the lamp 10 are pivoted when screwing the lamp 10 in the contact carrier 12.
  • the recesses 14, 16 of the contact carrier 12 are provided with chamfers 50, so that it does not produce abutting edges, the insertion of the Kon- tact flags 6, 8 in the socket contacts of the contact carrier 12 complicate.
  • a headlight 1 in particular for a vehicle, with at least one reflector 2, which has at least one receptacle 4 for a contact lugs 6, 8 provided light source 10, wherein the electrical contacting of the light source 10 by means of at least one contact carrier 12 takes place.
  • the contact carrier 12 can be fixed directly to the reflector 2.
