Description of the utility model anineldu'ns: "Oil lamp holder, in particular for motor vehicle lights ¹ '

The firing refers to an incandescent lamp socket, in particular For ICraft vehicles, ordering from one with the reflector or a carrier part latchable Isolierstoffkö- * per that both {the incandescent lamp as well as the contact device takes up and these combined into an independent structural unit.

In the known fits of this type, the insulating body is usually designed as a hollow cylinder that tightly encloses the base of the incandescent lamp. In order to lock the incandescent lamp, channels are made in the inner wall of the raw cylinder, into which the pimrtmgs ^ pins arranged as the lamp base engage in the manner of a retainer. ¥ egen the non-electrically conductive property of the insulating Mus Rait Verden provided an additional Hasselcontakt extending body as {tape strip between the GlühlamOensocltel and the Isolierstoff-. When luminaires with such fits are put into operation for a long time, is lamp ens ο disgust a large "heat build-up. Because the heat is not radiated because of the almost fully toismatic covering of the base and is not dissipated because of the use of insulating material for the fit body. Such heat build-up is for the fit both in terms of the rough position of the bulb and the service life of the bulb from Haehteil.

It is now subject to inflation, while maintaining the body of the insulating material as a supporting element of the contact device and as a glow

lamp holder to circumvent the disadvantages mentioned above while continuing to meet the requirements that "with a closed Construction (lens, reflector and / or housing inseparably combined to form an assembly) the incandescent lamp from rüe2rr? Ärts it is interchangeable that when choosing the material for the housing, the reflector or another support part accommodating the incandescent lamp socket, the question of conductivity can be disregarded and that the lamp socket forms an easily preassembled, self-contained structural unit. According to the innovation? is the insulating body as Cap formed with a double side wall, with both side wall parts having at least two each associated zap edge have protruding and resiliently designed hooking links, of which those arranged on the outer wall part cooperate with the edge of the same wall part, the edge of the sin plug opening for the incandescent lamp in the reflector or in another beam part grip around, while the inner wall part in a corresponding manner a lamp holder made of current and heat-conducting material records. In addition, the outer wall part has at least one Make a thickening in which one parallel to the filamentous needle neck running Burehbruch for admission and self-fastening the strip-shaped contact spring is introduced. Sine such Version has the further advantage that neither for fixing the oils Contact and holding device for the incandescent lamp for self-fastening on the reflector or some other part of the carrier, the bidding or writing exiles known to be permanent and well known are necessary
