II. Darstellung der Erfindung II. Presentation of the invention

Es ist die Aufgabe der Erfindung, eine elektrische Lampe mit einem verbesserten Lampensockel und insbesondere mit verbesserten elektrischen Anschlüssen bereitzustellen.It is the object of the invention to provide an electric lamp with an improved Lamp socket and in particular to provide improved electrical connections.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den Unteransprüchen beschrieben.This object is achieved by the characterizing features of Patent claim 1 solved. Particularly advantageous embodiments of the invention are in described the subclaims.

Die erfindungsgemäße elektrische Lampe besitzt einen Lampensockel, einen lichtdurchlässigen Lampenkolben, mindestens ein vom Lampenkolben umschlossenes Leuchtmittel, mindestens zwei aus dem Lampenkolben herausgeführte Stromzuführungsdrähte zur Spannungsversorgung des mindestens einen Leuchtmittels und eine Halterung für den Lampenkolben sowie einen mit den als mindestens zwei Kontaktfahnen ausgebildeten elektrischen Anschlüssen der Lampe versehenes Kunststoffsockelteil, in dem die Halterung verankert ist. Erfindungsgemäß weisen die mindestens zwei Kontaktfahnen jeweils eine Nut auf, in der jeweils ein Stromzuführungsdraht durch eine Schweißverbindung mit der entsprechenden Kontaktfahne fixiert ist. Außerdem sind die mindestens zwei Kontaktfahnen erfindungsgemäß mit Mitteln zur Einfädelung der Stromzuführungsdrähte in die jeweilige Nut versehen. Der Lampensockel weist ferner wenigstens einen zur Durchführung der Verschweißung der Stromzuführungsdrähte mit den Kontaktfahnen dienenden Durchbruch auf.The electric lamp according to the invention has a lamp base, a translucent Lamp bulb, at least one enclosed by the lamp envelope Light source, at least two led out of the lamp envelope power supply wires to the power supply of the at least one lamp and a Holder for the lamp bulb and one with the as at least two contact lugs trained electrical connections of the lamp provided plastic base part, in which the holder is anchored. According to the invention at least two contact lugs each have a groove in each of which a power supply wire by a welded connection with the corresponding contact lug is fixed. In addition, the at least two contact lugs according to the invention with Means provided for threading the power supply wires in the respective groove. The lamp cap also has at least one for carrying out the welding the power supply wires with the tabs serving breakthrough.

Die vorgenannten erfindungsgemäßen Merkmale der Lampe ermöglichen es, die Kontaktfahnen in das Kunststoffsockelteil einzuspritzen und auf zusätzliche Mittel zur Abdichtung des Lampensockels gegen das Eindringen von Luftfeuchtigkeit, wie zum Beispiel Silikonschläuche oder Vergußmasse, zu verzichten. Außerdem ist auch kein Deckel zum Verschließen des Sockelinnenraums erforderlich. Der Schweißverbindung zwischen Stromzuführungsdrähten und Kontaktfahnen erfolgt bei der erfindungsgemäßen Lampe, beispielsweise mit Hilfe eines Lasers, durch einen winzigen Durchbruch im Lampensockel. Der vorgenannte Durchbruch ist vorteilhafterweise in der Halterung und nicht im abgedichteten Kunststoffsockelteil angeordnet. Vorteilhafterweise werden zur Herstellung der vorgenannten Schweißverbindung, wegen der geringeren Schmelztemperatur, die aus Stahlblech bestehenden Kontaktfahnen und nicht die aus Molybdän gefertigten Stromzuführungsdrähte erhitzt.The above-mentioned features of the lamp according to the invention make it possible to Injecting tabs into the plastic base and additional means for sealing the lamp cap against the ingress of atmospheric moisture, such as For example, silicone tubing or potting compound to dispense. Besides, too no lid required to close the socket interior. The welded joint between power supply wires and tabs takes place in the inventive Lamp, for example with the help of a laser, through a tiny Breakthrough in the lamp base. The aforementioned breakthrough is advantageously in the holder and not arranged in the sealed plastic base part. advantageously, be used for the preparation of the above-mentioned weld, because the lower melting temperature, the contact lugs made of sheet steel and not heating the power supply wires made of molybdenum.

Die Mittel zur Einfädelung der Stromzuführungsdrähte weisen vorteilhafterweise für jede Nut zwei Stege auf, die die Nut seitlich begrenzen, wobei die der Nut zugewandte Kante zumindest eines dieser Stege mit einer Schrägen versehen ist. Bei dem besonders bevorzugten Ausführungsbeispiel der Erfindung weisen die der Nut zugewandten Kanten beider Stege jeweils eine Schräge auf. Diese Schrägen gewährleisten bei der Lampenmontage ein automatisches, problemloses Einfädeln der Stromzuführungsdrahtenden in die Nuten der Kontaktfahnen. Vorteilhafterweise besitzen die beiden die Nut begrenzenden Stege unterschiedliche Längen. Dadurch kann der längere Steg dem einzufädelnden Stromzuführungsdraht als Führungshilfe dienen. Der kürzere der beiden Stege weist vorteilhafterweise eine geringere Breite als der längere Steg auf. Das erleichtert das Verschweißen von Stromzuführungsdraht und Kontaktfahne, weil zum Verschweißen der beiden vorgenannten Bauteile nur das Material des kürzeren Steges kurzzeitig über dessen Schmelzpunkt erhitzt werden muß. Nach dem Erstarren des erhitzten Materials ist der Stromzuführungsdraht mit dem kürzeren Steg durch eine Schweißverbindung verbunden.The means for threading the power supply wires advantageously have for each groove on two webs, which bound the groove laterally, wherein the groove facing Edge of at least one of these webs is provided with a bevel. In which Particularly preferred embodiment of the invention have the groove facing Edges of both webs each have a slope. These slopes ensure during lamp assembly, an automatic, trouble-free threading of the power supply wire ends into the grooves of the contact lugs. Advantageously possess the two webs delimiting the webs different lengths. This allows the longer bridge to serve the umzelnden power supply wire as a guide. The shorter of the two webs advantageously has a smaller width than the longer bridge on. This facilitates the welding of power supply wire and Contact lug, because for welding the two aforementioned components only the Material of the shorter web are briefly heated above its melting point got to. After solidification of the heated material of the power supply wire with connected to the shorter web by a welded joint.

Die mit den Stromzuführungsdrähten 12, 13 verschweißten L-Schenkel 16b, 17b erstrecken sich bis in den von der im Kunststoffsockelteil 15 verankerten Trägerhülse 14b gebildeten Innenraum. Die Trägerhülse 14b ist auf der Höhe der Stege 16d, 16e, 17d, 17e mit einem Durchbruch 18 versehen, über den die Laser-Verschweißung der Stromzuführungsdrähte 12, 13 mit den kurzen Stegen 16e, 17e der entsprechenden Kontaktfahne 16, 17 nach der Montage des Lampensockels erfolgt.The electrical connections 16, 17 of the lamp consist of two metallic contact lugs 16, 17, each welded to one of the power supply wires 12, 13 are (not shown in Figure 1). The contact lugs 16, 17 are made of a Made of sheet steel and injected into the plastic base part 15 of the lamp cap. They 16, 17 each consist of an L-shaped sheet steel. One each Leg 16a, 17a of the L-shaped contact lugs 16, 17 is formed as a plug contact, while the other leg 16b, 17b is provided with a groove 16c, 17c, in each of the angled end 12a, 13a of a power supply wire 12, 13th threaded. The areas normally hidden in the cross-section of FIG the contact lugs 16, 17 are shown in dashed lines in Figure 2. The angle range the L-shaped contact lugs 16, 17 is sealed in the plastic base part 15 injected and therefore usually not visible. The grooves 16c, 17c are respectively bounded laterally by two differently long webs 16d, 16e and 17d, 17e. Both webs 16d, 16e and 17d, 17e each have their groove 16c, 17c facing edge 16f, 17f, which is for threading the power supply wire 12, 13 serve in the groove 16c, 17c. The shorter bridge 16e, 17e has a smaller width than the longer web 16d, 17d. The welded connection between the power supply wires 12, 13 and the contact lugs 16, 17 is through Brief heating of the material of the shorter webs 16e, 17e over the Melting point produced by means of a laser. After the solidification of the melt is the angled end 12a, 13a of the power supply wire 12, 13 with the shorter Bridge 16e, 17e connected.
