Definitions

  • the invention relates to a lamp holder for a vehicle headlight, the has a holder in which the lamp can be preassembled, and which by means of a Locking device can be attached to a lamp neck of a reflector, the holder has bayonet flaps on the lamp neck of the reflector are lockable.
  • EP 0 574 013 B1 describes a lamp holder for a motor vehicle headlight known, which consists essentially of a holder into which a lamp is used or pre-assembled.
  • the unit consisting of holder and lamp points towards the lamp a bayonet flange with three radially to a holder or lamp longitudinal axis Arranged bayonet flaps that in a lamp neck of a reflector corresponding recesses can be locked.
  • the recesses are too
  • a disadvantage of the known lamp holder is that the spring is relative costly to attach to the lamp neck of the reflector with three screws got to.
  • Another disadvantage is that the bayonet flaps are arranged on the lamp side and therefore the lamp cannot be used universally for different reflectors.
  • the object of the present invention is therefore the known lamp holder to improve that they are inexpensive to manufacture, easy to assemble and the lamp to be used is universally applicable.
  • the holder is a connector housing and a Has spring plate part surrounding the plug housing, with which the two Bayonet flaps and edge portions of the holder are integrally formed, the Edge sections can be placed on the lamp under pre-tension and the lamp on the reflector.
  • the spring sheet metal part carries both the connector housing as well as the lamp.
  • the spring arms have towards the holder a first leg bent towards the reflector, which via a U-shaped curvature into a second bayonet flap Leg passes over and the free end is directed away from the reflector.
  • the Bayonet lobes at an acute angle to a longitudinal axis of the holder arranged.
  • the Bayonet flaps have a concave latching waist at their free ends Locking position the adjacent screw or its screw head snaps into place. To facilitate locking, the bayonet flaps have theirs free ends, in an unlocked position towards the screw head, one Ramp.
  • the locking process is carried out by the arrangement of bevels simplified.
  • the arrangement of a concave locking waist on the bayonet flaps enables simple locking or locking of the bayonet flaps opposite the screws or the screw heads.
  • the Screw heads on their undersides facing the free ends of the screws towards a cone.
  • the Lock By arranging a cone on the underside of the screw heads, the Lock the screws further in relation to the locking waists of the bayonet flaps favors so that on an additional locking clip that an unwanted unlocking the lamp holder should prevent, can be dispensed with.
  • the Spring arms arranged on a spring sheet metal part, which with a connector housing Resilient locking tabs and corresponding locking parts can be connected to the connector housing is.
  • the a plug housing can be connected in a self-latching manner, assembly is simplified of the holder considerably.
  • the lamp can easily be held in the holder, which is formed by the spring sheet metal part and the connector housing become. In particular, this also makes it easy to change the lamp Blind assembly possible.
  • a lamp holder 1 for a vehicle headlight consists essentially of a holder 2 and a lamp 3.
  • the lamp holder is from the rear 4 of a reflector 5 of a vehicle headlight can be inserted into the reflector 5.
  • the holder 2 consists of a spring sheet metal part 6 and a plug housing 7, the via connector sleeves, not shown, with the electrical leads connected is.
  • the spring plate part 6 has on its transverse to a holder longitudinal axis 8 arranged bottom 9 on two opposite spring arms 10.
  • the Spring arms 10 point towards the holder 2 or towards the bottom 9 in the direction of the reflector 5 bent leg 11.
  • the first leg 11 goes over a U-shaped curvature 12 in a second leg 13, the free end of the reflector 5 is directed away and forms a bayonet flap 14.
  • the Bayonet tab 14 is at an acute angle with respect to the holder longitudinal axis 8 arranged.
  • the bayonet flap 14 has a concave at its free end Resting waist 15 on.
  • the bayonet flap 14 has at its free end in Locking direction on a bevel 16.
  • the spring plate part 6 has two resilient locking tabs 17 each with a snap opening 18 at the free end.
  • the locking tab 17 lock with their locking openings 18 on two corresponding locking parts 19 on Connector housing 7.
  • the connector housing 7 has two transverse to the locking parts 19 opposing struts 20 on their free ends
  • Have latching hooks 21 which engage in corresponding latching openings 22 in the bottom 9 intervene and get caught there.
  • the locking hook 21 in the direction of the connector housing 7 are upstream of two opposing stops 23 against the Strike the bottom 9 and serve the connector housing 7 as a support.
  • the spring plate part 6 has at its edge a parallel to the longitudinal axis 8 of the holder arranged stop lip 24 against which the lamp 3 with a recess 25 of a base ring 26 arranged radially to the holder longitudinal axis 8.
  • the spring sheet metal part 6 has next to the stop lip 24 a locking clip 28 resilient transversely to the longitudinal axis 8 of the holder.
  • the reflector 5 has on its rear 4 a lamp neck 29 in which the Holder 2 with lamp 3 can be inserted and locked.
  • the bayonet flap 14 two threaded sleeves 30 are arranged on the side of the lamp neck 29, in a screw 31 is screwed in with a screw head 32 can.
  • the threaded sleeve 30 has a bevel 33 towards the longitudinal axis 8 of the holder.
  • the screw head 32 has on the threaded sleeve 30 or the reflector 5 facing bottom 34 a cone of about 15 degrees.
  • the lamp neck 29 has on its inner edge 36 parallel to the longitudinal axis 8 of the holder a locking groove 37 in which the spring plate part 6 in its locking position its locking clip 28 engages.
  • the spring plate part 6 has no locking clip so that the locking groove 37 can also be dispensed with on the lamp neck 29.
  • the spring plate part 6 is on the Plug housing 7 placed so that the locking tab 17 or the locking openings 18 engage with the latching parts 19, the spring struts 20 of the plug housing 7 with their stops 23 are supported on the bottom 9 of the spring plate part 6 and their locking hooks 21 get caught in the locking openings 22 of the base 9.
  • the lamp 3 for example as an H 7 lamp is formed, is inserted into the connector housing 7.
  • the locking clip 28 also snaps into the corresponding locking groove 37 of the inner edge 36 or the lamp neck 29.
  • the holder only needs to be replaced from its locked position opposite direction in the unlocked position and the holder 2 be pulled out of the reflector 5.
  • the lamp 3 can now be removed and the holder 2 with the lamp 3 replaced in the lamp neck 29 of the Reflector 5 are used.
  • the lamp holder 1 is thus in the reflector 5 on the one hand from the Bayonet tab 14 and on the other hand consisting of the screw heads 32 Locking device locked.
  • FIG. 7 to 10 a vehicle headlight is shown in which the Spring plate part 6 and the connector housing 7 exclusively by a single Locking device are connected to each other, the resilient locking tab 17 of Spring sheet metal part 6 and nose-like locking parts 19 of the connector housing.
  • the connector housing 7 is with electrical leads, not shown connected and between the locking tab 17 pointing away from the reflector used.
  • the connector housing engages with plug connections for flat plugs 36 of the lamp 3 into a central through opening of the spring sheet metal part 6.
  • FIG. 8 is the lamp 3 with its flat plugs 36 in the plug housing 7 introduced and thereby held with the holder 2.
  • the Lamp 3 After passing through a glass bulb of the lamp 3 through an opening 37 in the reflector 5 is the Lamp 3 with a flange-like base ring 26 on a circumferential Edge area 38 of the opening 37 of the reflector 5.
  • the edge area 38 is from a separate annular one set in the opening 37 of the reflector 5 Version part 39 formed.
  • the socket part 39 has two opposite angled bayonet flags 40, in the undercuts of the holder 2 with engages his bayonet flap 14.
  • the resilient bayonet lugs 14 of the holder 2 are under tension on the undercuts 41 of the bayonet lugs 40 and press the base ring 26 of the lamp 3 against the edge region 38 of the Reflector 5 (see Fig. 10).
