Definitions

  • the invention relates to a socket device for a lamp Vehicle headlights with one arranged on the rear of the reflector Socket ring, with a swiveling U-shaped retaining spring, which for Serves the lamp in the holder ring and the tavern connecting web in a bearing shell facing towards the reflector Projection of the mounting ring is arranged and in the bearing shell contact surfaces of the mounting ring pointing away from the reflector are held.
  • Such a mounting device for a lamp of a vehicle headlight is known from DE 37 29 984 C1.
  • the one that can be attached to a reflector Socket ring is sleeve-shaped and in the injection molding or Die casting process manufactured.
  • the lamp is from the back of the Headlights inserted into the central opening of the lampholder and lies with its base flange on a contact surface of the mounting ring.
  • On the base flange are the legs of an existing spring wire U-shaped retaining spring under tension and hold the base flange against the bearing surface of the mounting ring.
  • One leg of the U-shaped Retaining spring is longer and engages behind with its free end section the edge of a holding opening made in the mounting ring.
  • the the Leg connecting straight web of the retaining spring is in a bearing shell Projection rotatably arranged.
  • the projection is directed radially inwards and has the bearing shell on the side facing the reflector.
  • To the To be able to remove the bearing shell of the projection is one in the mounting ring additional through opening introduced.
  • the through opening is relative designed large, so that the service life of the Manufacture of the tool used to mount the ring is not downsized.
  • the mounting ring would have to be even larger for reasons of stability Have external dimensions if a larger one to accommodate the lamp central opening and a larger surface for the Base flange would be necessary.
  • the retaining spring lies with side sections its straight web on contact surfaces facing away from the reflector Setting ring. The web is through the contact surfaces of the mounting ring held radially in the bearing shell. The sections of the Both legs of the retaining spring border on system surfaces facing one another Holding elements of the mounting ring. Because of the latter contact surfaces Retaining spring axially supported to the swivel axis. To assemble the retaining spring the two bars have to be pushed very far together, so that the web connecting the legs bends and into the bearing shell the lead can be used. Such an assembly is cumbersome and time-consuming, since it can only be carried out manually.

  • the Bearing point for the retaining spring is simple and inexpensive to manufacture.
  • the two holding approaches are very stable with the mounting ring and stiffen the mounting ring when the two retaining lugs are formed by ribs are that down to the side of the mount ring facing the reflector extend and are molded onto this side.
  • the retaining spring After pivoting the retaining spring towards the mounting ring, the retaining spring lies with their legs under tension on the lamp and holds the lamp on the frame ring.
  • the retaining spring is with the free end section at least one leg releasably with a holding element of the mounting ring connected.
  • the mounting ring is not in additional through opening weakening its stability is necessary if the mounting ring on the opposite of the pivot bearing and the Has an integrally formed holding element, on which the retaining spring with the free end portion of at least one leg is releasably attached.
  • the mounting ring builds as small as possible radially to its central axis when the Attachments to a support surface of the mounting ring for a base flange adjoin the lamp and the holder ring between the holding element for the Retaining spring and the pivot bearing at least in sections with its radial outward facing outer surface to the outer edge of the base flange runs adjacent to the lamp.
