Definitions
- the invention relates to a lamp holder for Motor vehicle headlights according to the preamble of claim 1 and one Motor vehicle headlights in which the lamp holder is used.
- the Lamp holder for Motor vehicle headlights known with a lamp on a reflector of the headlight can be attached.
- the Lamp holder has a housing in which the lamp is pre-assembled and that on the reflector by means of a Locking device can be attached.
- the lamp has one whose base protrudes electrical contact tab, by which is the plus side connection of the lamp.
- the ground-side connection of the lamp takes place via the metallic base plate.
- the housing of the lamp holder is consistently open, so that no sealing is present and moisture and dirt in the Lamp holder and the reflector can penetrate.
- the closest prior art GB 2 218 793 A describes one Lamp holder for a motor vehicle headlight according to the preamble of the claim 1.
- the lamp In the known lamp holder, the lamp is over the (two-part) lamp holder only indirectly attached to the reflector. In the manufacture of the lamp holder Manufacturing tolerances can lead to the fact that when attached to the reflector Lamp holder and lamp arranged in the lamp holder, the lamp does not is always arranged exactly in the desired position relative to the reflector. This can vary from headlamp to headlamp Light distributions result in what is undesirable for reasons of traffic safety.
- the object of the present invention is to provide a generic lamp holder To provide, which eliminates the disadvantages of the known lamp holder.
- 1 to 3 show one in a reflector inserted lamp holder with a lamp inserted in it.
- Figure 4 shows another lamp holder, not according to the invention.
- FIGS. 1 to 3 show a lamp holder according to the invention for a Motor vehicle headlamps shown.
- the lamp holder is used for Inclusion of a lamp, for example a commercial one H7 incandescent lamp 10 and its arrangement in a reflector 12 the headlight.
- the lamp holder shows one Plastic housing 14 with a substantially round cylindrical shape, which is a main body of the Lamp holder forms and that towards the reflector 12 open end and pioneering a closed one End.
- the housing 14 is thus pot-shaped formed, the arranged at the closed end Ground points away from the reflector 12.
- the lamp 10 has two electrical contact tabs 16 projecting through their base, with which the lamp 10 in advance from its open end The direction of arrow 18 can be inserted into the housing 14.
- An adapter for electrical contacting is in the housing 14 arranged the lamp 10, the protruding into the housing 14 Has contact elements 20 with which the contact tabs 16th the lamp 10 when the lamp 10 is inserted into the housing 14 be put together.
- the adapter also points to the Contact elements 20 electrically connected others Contact elements 22 on the outside of the housing 14 protrude.
- the contact elements 22 are of one approach 24 of the housing 14 in which a not shown Plug part is insertable, via which the contact elements 22nd can be connected to a power supply.
- the Mounting direction 23 of the connector part is rectangular to the direction of insertion 18 of the lamp 10, so that the installation depth 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 of Solid material surround so that the housing 14 at this end is completely closed.
- the Contact elements 20 and 22 from the plastic material of the Injection molded housing 14 and only the ends of which protrude into the Housing 14 in or out of this.
- FIGS. 1 and 2 there are several in the housing 14 arranged inwardly facing lugs 25, between which the Base plate 11 of the lamp 10 is received and latched is held when the lamp 10 is inserted into the housing 14 is.
- the lamp 10 is captive in the housing 14 recorded and forms a with the lamp holder pre-assembled unit.
- the lamp 10 is preferably only in can be inserted into the housing 14 at a certain rotational position, so that they have a defined position with respect to the housing 14 occupies.
- a spring element 26 in the form a diaphragm spring arranged in a groove 28 in the Housing 14 is clamped.
- the diaphragm spring 26 is one wave-shaped curved disc made of resilient steel sheet the base plate 11 of the lamp 10 comes to rest and on the base plate 11 towards the open end of the housing 14 Exerts pressure.
- the throwing ring 30 is supported on the open end of the housing 14 circumferentially projecting from the housing 14 Ring shoulder 32 from.
- the collar ring 30 has at least one, preferably several, for example two, over the circumference of which has bayonet hooks 34 distributed.
- the Bayonet hooks 34 project outward from the coupling ring 30 and have their ends facing the open end of the housing 14.
- the collar 30 and the housing 14 are preferred made by injection molding with the collar 30 in a 2-component injection molding process together with the Housing 14 can be made.
- the Collar ring 30 molded directly around the housing 14 and can on this between the ring shoulder 32 and one another annular shoulder 36 can be arranged captively.
- the Housing 14 has near its open end in its Outer circumference on a circumferential annular groove 38 into which a elastic sealing element 40 in the form of a sealing ring is inserted.
- the reflector 12 has one in its apex area Opening 42 on the one of the rear of the Reflector 12 protruding neck 44 is surrounded.
- the neck 44 points in its outer circumference according to the number of Bayonet hook 34 as shown in Figure 3 L-shaped Recesses 46, which in their from the reflector 12th technological end region each approximately parallel to the longitudinal axis 45 of the neck 44 and those in their other End regions run over the circumference of the neck 44 and to Reflector 12 can run obliquely.
- the Throw ring 30 is in a rotational position, in which the bayonet hook 34 in the direction of Longitudinal axis 45 ends of the recesses 46 can occur. After a certain insertion path of the The collar 30 can be rotated, so that its bayonet hook 34 in the circumference of the neck 44th sliding area of the recesses 46 slide. Doing so the coupling ring 30 is locked on the neck 44 of the reflector 12 and which fixes the lamp holder to the reflector 12.
- the Lamp 10 comes with its base plate 11 on the opening 42 surrounding edge of the reflector 12 to the system and will pressed against it by the diaphragm spring 26.
- the housing 14 is preferably by a appropriate training only in a certain Rotatable position in the neck 44 so that the Lamp 10 in a predetermined position with respect to the reflector 12 is located.
- the neck 44 can, for example have one or more webs on its inner circumference, which engage in corresponding slots in the housing 14.
- FIG. 4 shows another lamp holder that is not according to the invention shown, below only from Embodiment different features of the Lamp holder are described.
- the lamp holder 4 are as Locking device on the housing 1 several, for example two diametrically opposed resilient locking hook 50 arranged.
- the one from the back of the Projector 12 protruding neck 42 surrounding its opening 44 has on its outer jacket corresponding to the number of Latching hook 50 of the lamp holder has a number of depressions 52, with shoulders 54 facing the reflector 12, on which the Latching hooks 50 of the lamp holder can be snapped into place.
- the Latching hooks 50 are preferably in one piece with the housing 14 trained and can each with a web 56th be connected, which is elastically deformable.
- the locking hooks 50 extend from the webs 56 to the reflector 12 out. On each web 56, a different from each Reflector 12 extending arm 58 may be arranged.
- everyone Snap hook 50 forms one with the associated arm 58 two-armed lever, with the webs 56 as a pivot bearing.
- a flange 59 open toward reflector 12 formed with a groove 60 into which the elastic sealing ring 40 is inserted. When the lamp holder is installed, this appears End of the neck 44 of the reflector 12 in the groove 60 and comes into contact with sealing ring 40.
- a bow spring 62 is arranged as a spring element, by the with the lamp holder of the base plate 11 of the Lamp 10 is held in the system on the reflector 12.
