Von der der Vorderseite der 5 Glühlampenfassung weist Stromzuführungen 36 und Werkplatte zugewandten Oberfläche der Fhmschteile 38 auf. Die Stromzuführung 38 stellt ein Metallteil 44 erstrecken sich Befestigungselemente, die durch dar, das rechtwinklig umgebogen ist und in einer Ausnachgiebige Glieder 46 gebildet sind. Diese Befesti- höhlung in einem vom Sockelende 32 der Lampengungselemente umfassen einen dem Flanschteil be- fassung vorspringenden Bereich angeordnet ist. Die nachbarten Schaftteil 78, dessen Durchmesser nicht io Stromzuführung 38 umfaßt hingegen einen gewellten grater als derjenige einer zugehörigen öffnung ist, Teil 90, der im Sockelende eingeformten Gewindedie in der Werkplatte zum Festlegen der Giühlam- gangen 34 entspricht. Die Stromzuführung 36 ist so penfassung vorgesehen ist An den Schaftteil 78 angeordnet, daß ihr inneres Ende von der eingeschheßt sich ein erweiterter Kopfteil 80 an, der am schraubten Glühlampe zurückgefedert wird.

Pressed together from the free edges until the entire head part 80 extends over the webs 42 from flange parts 44, which are snapped onto the opening edge and the incandescent seal against the pre-rotation of the work plate and fix the lamp holder in this way,
limit the movement of the incandescent lamp socket into the end of the opening facing away from the flange 44. The surface of the Fhmsch parts 38 facing the front side of the incandescent lamp socket has power supply lines 36 and the work plate. The power supply 38 is a metal part 44 extending through fasteners, which is bent at right angles and formed in a resilient member 46. This fastening cavity is arranged in a region that protrudes from the base end 32 of the lamp narrowing elements and encompasses the flange part. The adjacent shaft part 78, the diameter of which does not include the power supply line 38, on the other hand, is a corrugated grater than that of an associated opening, part 90, which corresponds to the thread formed in the base end in the work plate for fixing the Giühlam- gangen 34. The power supply 36 is provided in such a way that it is arranged on the shaft part 78 that its inner end encases an enlarged head part 80 which is spring-loaded back on the screwed light bulb. A free end 82 is pointed. This end region 82 15 the incandescent lamp socket 10 screwed in extends in the same. The direction in which the incandescent lamp is protected by the basket part 40 of the lamp holder is backwards towards the shaft part 78. This basket part 40 comprises longitudinally and transversely widened and resiliently compressible. While ribs 45, which connect the webs 42 with the base 32 of the fastening elements penetrating the bulb socket. In the transverse ribs 45, tapered free ends 82 in the opening of the factory are, at 48, spring tabs for placing a plate. During the further insertion movement, openings in the lens covering the work plate are seen in front of the flexible edge parts 84, 85 of the head part 80.

The invention is based on the object of a

Claim: To create an incandescent lamp holder whose insertion movement in an opening of a work plate

Incandescent lamp holder, the flange parts from the front end only slightly protrude from the front of the work plate of a work plate in a 5 provided in this, so that one can be inserted onto the lamp opening and the two axially mountable cover lens extending these flange parts, molded in one piece from plastic, covers and is able to fit closely to the front of the work fitting and through the opening a plate. Such a lamp socket can be guided half-parts, each of which is integral with these, can safely be attached to attaching an incandescent lamp to formed and the two half-parts to one another io the inner wall of a drum of a laundry dry connecting elements, and electrical device, since then includes the sensitive contact parts, the Half-pieces are borrowed items of laundry when rotating the drum radially extending, the import movement is not hindered or even damaged,

The invention relates to an incandescent lamp socket which is made of plastic, there is no risk of the front side of a work plate into an opening provided by the voltage-carrying socket and the incandescent lamp to the work plate a leakage current two axially extending, can be plastic form 40 connecting in one piece, nor that the Glühgeformte, matching and through the opening auswechselnde person with the lamp spannungeinführbare _s half-parts, which can each come in one piece with these leading replaced into contact,

forms. In order to prevent the two halves carrying the two halves, which are formed separately in one piece, from being pressed together, a plug, which is connected to one another by means of pins 74, is inserted between the two incandescent lamps. These pins are integrally inserted with the half-part 12 half-parts when the edges of the opening 60 are formed and protrude from this. You are now locked in the two grooves. These extend through corresponding openings in the known incandescent lamp socket has the disadvantage that half-part 14 passes through. The overhanging the openings of the cover plug and the ends of the pins bearing the grooves are deformed by the action of heat and pressure areas of the half-parts on the front side of the work plate, so that both half-parts 12 and 12 protrude far. In addition, the cover 65 14 are firmly connected to each other,
