Lamp socket of insulating material for H7 lamps

The invention relates to a lamp holder Insulating material for H7 lamps Automotive lighting, the lamp socket Plug sockets made of electrically conductive material supports, into which the connection contacts of the H7 lamp are inserted, and radially outside the Plug-in region of the H7 lamp plug connection means from electrically conductive material supports each with one of the sockets are electrically connected and the inserted or in plug connectors Plug connectors are plugged, the most Reflector or housing of the lamp socket be equipped headlight fixed and Connection cables are connected.

Such lampholders in the art known. The issue here so-called H 7 lamps have a glass lamp bulb with a Filament on which in a sturdy assembly element the H 7 lamp is integrated. This element quasi an adapter represents the two connectors comprises, projecting from the side of the holder, which the lamp bulb is opposed. The H 7-lamp is usually used in appropriate Plug contacts of the lamp holder used. Of the Adapter H 7 lamp has irregular To contour shapes, as well as the corresponding Receiving the lamp socket to a to make fool proof Insertion facility. The completed with the H7 lamp bulb socket is then in a corresponding opening of Headlamp housing or reflector of Headlamp used, whereby at the Lampholder fixed further contacts are connected to respective terminal contacts are steckverbindbar that at the reflector or at the The headlight housing are fixed and to which the respective supply cables are posted.

In such arrangements, it is extremely important that the filament positioned exactly and is aligned. Only this is a safe Focussing distance. Even small deviations of the exact position mean that no secure more focussing is achieved such that the appropriately equipped headlights inadequate shines. Due to manufacturing tolerances and Mounting inaccuracies occur in the known Training results in the H 7 lamp not exactly for Reflector or housing of the spotlight is oriented so that the proper Function is not guaranteed.

Starting from this prior art, the Invention has the object, a lamp socket to provide generic type, with the in easily precise positioning in particular, the filament of the H 7 lamp relatively the reflector or housing of the spotlight is achieved.

To achieve this object it is proposed that the sockets floating on the lamp socket are supported.

By this design it is achieved that at the Assembly sequence first the H 7 lamp with Connecting contacts properly into the sockets can be inserted. Now, if the H as the 7-lamp stocked lamp socket in the corresponding Hole of the reflector or of the Headlamp housing is used, is the Plate of the adapter of the H 7 lamp at a respective stop collar of the reflector or the headlamp housing is flush with, whether the lamp holder itself as a result of manufacturing or Assembly tolerances on the reflector or inexact Headlight housing is mounted. The H 7 lamp may be relatively in the plug-in position for Moving lamp socket slightly, so that in each Case an exact installation of the plate of the adapter the H 7 lamp on the collar of the reflector or of the Of the headlamp housing is achieved, which turn, is essentially to ensure that the H 7 lamp is precisely aligned, in particular the Filament precisely relative to the reflector or Headlamp housing is aligned. The floating arrangement of the sockets at the Lamp socket can like a gimbal Compound or the manner of a resiliently bendable Connection between socket and bulb socket be achieved.

To even a simple merging of Plug-in connection means and the plug connection parts at Reflector or housing of the spotlight to achieve, it is provided that the Plug connection means rigidly attached to the lamp socket are supported and the plug connectors on Reflector or housing of the headlamp floating are fixed.

In this way, it is ensured that even if the lamp socket is not exactly coaxial with the Hole of the reflector or is the headlight housing aligned, the Plug connection means in the plug connection parts can be introduced, because the plug-in connection parts slightly in the transverse direction to the insertion direction are movable, so that even when the Connecting direction slightly different orientation the plug connection means a secure Connector while merging parts is made possible.

A preferred development is seen in that each socket via a footbridge with is connected to a plug connector means, which resiliently with some areas at the bottom of Lamp holder supports.

Thereby, the respective plug connection means quasi maintained resiliently so that Alignment inaccuracies easily compensated can be.

It is particularly preferred that the Footbridge on the socket, leaving the plug-in region is formed, the Anformungsbereich distance from the bottom of the having lamp socket, the Anformungsbereich projecting towards the bottom bulging arms extending with ski-like support regions at the bottom of Lampholder support and one of the arms integrally connected to a plug connection means is.

For the purpose of floating support is also provided that each receptacle with play in a receiving channel in the bottom of the lamp socket is used and by means of a locking element, which engages in a recess of the channel wall is engaged, held captive.

Furthermore it is preferably provided that the Plug connection means formed by tabs are, the captive in with hooking Pockets of the socket body are inserted and parallel with its plug-in area to the insertion direction the H 7 lamp and the lamp socket projecting.

For the purpose of the floating arrangement of the Plug-in connection parts is preferably provided that the plug connectors on bends, where Cable stop means are formed, in pockets of Reflector or housing of the headlight fix and are held captive, whereby the Bends around hairpin-like curved elements projecting that the actual plug connection parts form, wherein the hairpin-like shape about tangential to the substantially cross-sectionally circular lamp socket runs addressed.

This is even with slight inclinations the plug-in connecting means relative to the Plug-in connection parts a precise feeding of Parts guaranteed to each other because the Plug connectors with their hairpin-like Training the direction and arrangement of the Plug connection means rigidly to the Lamp socket are mounted, can follow.

Preference is intended that the radially inner limb of the hairpin-like shape rounded to the shape of the lamp socket is and the outer leg approximately rectilinearly (Tangential) runs.

In known manner it is provided that the Bottom of the lamp socket projecting a collar as confusion-free insertion of a plate serves as part of the H7 lamp.

Preferably it is provided that the collar in Plug-in direction open slots as penetration for having the bridge segments, with the Plug connection means are connected.

It is particularly preferred that the collar Having in the plug recesses open the access to the edge of the plate a inserted H7 lamp form.

By these recesses, it is possible to Adapter H 7 lamp with 3 fingers of one hand to The purpose of dismantling or for the purpose of to take assembly and according to the use lamp socket or from the Plug-in position to break away from the bulb socket.
