  • the invention relates to a lamp holder for motor vehicle headlights and a motor vehicle headlight, in which the lamp holder is inserted according to the preamble of claim 1.
  • a lamp holder for motor vehicle headlights with which a lamp can be attached to a reflector of the headlight.
  • the lamp holder has a housing in which the lamp can be preassembled and which can be fastened to the reflector by means of a locking device.
  • a spring element is arranged in the housing, by means of which pressure is exerted on the lamp towards the reflector, so that the base plate rests on the reflector.
  • the lamp has an electrical contact tab protruding from its base, through which the lamp is connected on the plus side. The lamp is connected to the ground via its metallic base plate.
  • the housing of the lamp holder is continuously open, so that no seal is present and moisture and dirt can penetrate into the lamp holder and the reflector.
  • a plug part can be assembled with the contact lug of the lamp, via which the lamp is terminated on the plus side.
  • the reflector has a metallic collar on which the base plate of the lamp comes to rest and on which a cable lug is clamped. The electrical terminations of the lamp are thus difficult to manufacture.
  • the lamp holder according to the invention for motor vehicle headlights with the features according to claim 1 has the advantage that a secure seal between this and the reflector is achieved and that the electrical connections of the lamp are easily possible on the lamp holder.
  • FIG. 1 shows a lamp holder inserted into a reflector according to a first embodiment with a lamp inserted therein in a longitudinal section along line II in FIG. 2
  • FIG. 2 shows the lamp holder according to the first embodiment in a section along line II-II in FIG. 1
  • FIG 3 a partial intention of the reflector and the lamp holder in Arrow direction III in FIG. 2
  • FIG. 4 the lamp holder according to a second exemplary embodiment in a section along line II-II in FIG. 1.

  • the lamp holder has a housing 14 made of plastic with an essentially round cylindrical shape, which forms a base body of the lamp holder and which has an open end towards the reflector 12 and, pointing away from it, a closed end.
  • the housing 14 is thus pot-shaped, the bottom of which is arranged at the closed end pointing away from the reflector 12.
  • the lamp 10 has two electrical contact tabs 16 projecting through its base, with which the lamp 10 can be inserted into the housing 14 from the open end thereof in the direction of the arrow 18.
  • an adapter for electrically contacting the lamp 10, which has contact elements 20 projecting into the housing 14, with which the contact tabs 16 of the lamp 10 are joined when the lamp 10 is inserted into the housing 14.
  • the adapter also has further contact elements 22, which are electrically connected to the contact elements 20 and project through to the outside of the housing 14.
  • the contact elements 22 are surrounded by a shoulder 24 of the housing 14, into which a plug part (not shown) can be inserted, via which the contact elements 22 can be connected to a power supply.
  • the Mounting direction 23 of the plug part is perpendicular to the direction of insertion 18 of the lamp 10, so that the installation depth of the lamp holder can be kept low.
  • connection of the contact elements 20 and 22 takes place through the closed end of the housing 14 and is surrounded by solid material, so that the housing 14 is completely closed at this end.
  • the contact elements 20 and 22 are preferably encapsulated by the plastic material of the housing 14 and only their ends protrude into or out of the housing 14.
  • a plurality of inwardly facing lugs 25 are arranged, between which the base plate 11 of the lamp 10 is received and held in a latching manner when the lamp 10 is inserted into the housing 14.
  • the lamp 10 is received captively in the housing 14 and forms a preassembled unit with the lamp holder.
  • the lamp 10 can preferably only be inserted into the housing 14 in a certain rotational position, so that it occupies a defined position with respect to the housing 14.
  • a spring element 26 in the form of a diaphragm spring is arranged in the housing 14 and is clamped in a groove 28 in the housing 14.
  • the diaphragm spring 26 is a wave-shaped curved disc made of resilient steel sheet, on which the base plate 11 of the lamp 10 comes to rest and exerts pressure on the base plate 11 towards the open end of the housing 14.
  • a swivel ring 30 made of plastic, which is rotatable relative to the latter, is arranged, which forms a locking device.
  • the coupling ring 30 is supported towards the open end of the housing 14 by a circumferential annular shoulder 32 projecting outwards from the housing 14.
  • the coupling ring 30 has at least one, preferably several, for example two the circumference of which has bayonet hooks 34 distributed.
  • the bayonet hooks 34 protrude outward from the collar ring 30 and have their ends facing the open end of the housing 14.
  • the collar ring 30 and the housing 14 are preferably produced by injection molding, the collar ring 30 in a two-component injection molding process together with the housing 14 can be produced.
  • the coupling ring 30 is formed directly around the housing 14 and can be arranged on the latter between the ring shoulder 32 and a further ring shoulder 36 so that it cannot be lost.
  • the housing 14 Near its open end, the housing 14 has a circumferential annular groove 38 in its outer circumference, into which an elastic sealing element 40 in the form of a sealing ring is inserted.
  • the reflector 12 has an opening 42 in its apex area, which is surrounded by a neck 44 projecting from the rear of the reflector 12.
  • the neck 44 has in its outer circumference in accordance with the number of bayonet hooks 34, as shown in FIG. 3, l-shaped recesses 46, which in their end region pointing away from the reflector 12 each run approximately parallel to the longitudinal axis 45 of the neck 44 and which extend in their other end regions extend the circumference of the neck 44 and can run obliquely towards the reflector 12.
  • the sealing ring 40 When assembling the lamp holder with the lamp 10 pre-assembled in this, it is inserted with the open end of its housing 14 ahead into the neck 44, the sealing ring 40 being clamped between the lamp holder and the neck 44 and sealing off the reflector 12 and the lamp holder.
  • the coupling ring 30 is in a rotational position in which its bayonet hooks 34 can enter the ends of the cutouts 46 running in the direction of the longitudinal axis 45. After a certain insertion path of the lamp holder, the coupling ring 30 can be turned, see above that its bayonet hook 34 slide into the area of the recesses 46 running on the circumference of the neck 44.
  • the coupling ring 30 is locked on the neck 44 of the reflector 12 and the lamp holder is fastened to the reflector 12.
  • the lamp 10, with its base plate 11, comes to rest on the edge of the reflector 12 surrounding the opening 42 and is pressed against it by the membrane spring 26.
  • a compensation of tolerances of the lamp holder, the lamp 10 and the reflector 12 is made possible by the diaphragm spring 26, so that a deposition of the base plate 11 of the lamp 10 on the reflector 12 is ensured independently of these.
  • the housing 14 can preferably only be inserted into the neck 44 in a specific rotational position, so that the lamp 10 is in a predetermined position with respect to the reflector 12.
  • the neck 44 can have one or more webs on its inner circumference, which engage in corresponding slots in the housing 14.
  • FIG. 4 shows the lamp holder according to a second exemplary embodiment, only features of the lamp holder that differ from the first exemplary embodiment being described below.
  • a plurality of, for example two, diametrically opposite, resilient latching hooks 50 are arranged on the housing 1 as a locking device.
  • the neck 44 projecting from the rear of the reflector 12 and surrounding its opening 42 has several recesses 52 on its outer jacket corresponding to the number of latching hooks 50 of the lamp holder, with shoulders 54 facing the reflector 12, on which the latching hooks 50 of the lamp holder can be latched.
  • the latching hooks 50 are preferably formed in one piece with the housing 14 and can each be connected to the latter via a web 56 which is elastically deformable.
  • the locking hooks 50 extend from the webs 56 to the reflector 12.
  • An arm 58 extending from the reflector 12 can also be arranged from each web 56.
  • Each locking hook 50 forms with the associated arm 58 a two-armed lever, with the webs 56 as a pivot bearing.
  • a flange 59 which is open toward the reflector 12, is formed on the housing 14 with a groove 60 into which the elastic sealing ring 40 is inserted. When the lamp holder is installed, the end of the neck 44 of the reflector 12 dips into the groove 60 and comes to rest on the sealing ring 40.
