II. Darstellung der Erfindung II. Presentation of the invention

Es ist die Aufgabe der Erfindung, eine elektrische Lampe mit einer verbesserten Andruckfeder und einer verbesserten Befestigung für die Andruckfeder bereitzustellen. Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den Unteransprüchen beschrieben. It is the object of the invention to provide an electric lamp with an improved pressure spring and to provide an improved attachment for the pressure spring. 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 und mindestens ein von dem Lampenkolben umschlossenes Leuchtmittel. Der Lampensockel weist ein metallisches Halterteil für den Lampenkolben, eine mit dem Halterteil verbundene ringförmige metallische Trägerhülse und ein mit den elektrischen Anschlüssen der Lampe versehenes Kunststoffsockelteil, in dem die Trägerhülse verankert ist, auf. Zur Montage der erfindungsgemäßen Lampe in einem Scheinwerferreflektor ist der Lampensockel mit einer als Blattfeder ausgebildeten Andruckfeder ausgestattet, die gewährleistet, daß die Lampe mit Klemmsitz in der als Lampenfassung ausgebildeten Reflektoröffnung des Scheinwerfers gehaltert wird. Die Andruckfeder liegt an der Innenwand der ringförmigen Trägerhülse an und greift durch einen Durchbruch in der Trägerhülse hindurch. Erfindungsgemäß weist die Trägerhülse zwei nach innen abgewinkelte Laschen auf, die jeweils mit einem Ende der Blattfeder verschränkt sind, und zwischen denen die Blattfeder mit Klemmsitz angeordnet ist. Dadurch ist die Andruckfeder auf zuverlässige und einfache Weise, das heißt, ohne zusätzliche Befestigungsmittel, unmittelbar an der Trägerhülse befestigt. Die abgewinkelten Laschen sind aus dem Material der Trägerhülse geformt. Die als Blattfeder ausgebildete Andruckfeder ist mit Klemmsitz zwischen den beiden abgewinkelten Laschen, die den Blattfederenden als Anschlag dienen, angeordnet.The electric lamp according to the invention has a lamp base, a translucent Lamp bulb and at least one of the lamp envelope enclosed Lamps. The lamp base has a metallic holder part for the Lamp bulb, an associated with the holder part annular metallic carrier sleeve and a plastic base part provided with the electrical terminals of the lamp, in which the carrier sleeve is anchored on. For mounting the inventive Lamp in a headlight reflector is the lamp base with a designed as a leaf spring pressure spring, which ensures that the Lamp with a press fit in the reflector opening formed as a lamp holder of the Headlamps is held. The pressure spring is located on the inner wall of the annular Carrier sleeve and engages through an opening in the carrier sleeve. According to the invention, the carrier sleeve has two inwardly angled tabs on, which are each entangled with one end of the leaf spring, and between where the leaf spring is arranged with a press fit. As a result, the pressure spring is on reliable and simple way, that is without additional fasteners, attached directly to the carrier sleeve. The angled tabs are from the Material of the carrier sleeve shaped. The trained as a leaf spring pressure spring is with a press fit between the two angled tabs, the leaf spring ends serve as a stop, arranged.

Jedes Ende der Blattfeder ist vorteilhafterweise mit mindestens zwei Zähnen ausgestattet, zwischen denen die jeweilige nach innen abgewinkelte Lasche der Trägerhülse angeordnet ist. Die vorgenannten Zähne ermöglichen das Verschränken des jeweiligen Blattfederendes mit der entsprechenden Lasche der Trägerhülse. Vorteilhafterweise bilden die abgewinkelten Laschen mit der Trägerhülse einen spitzen Winkel, wobei jedes Blattfederende in dem Bereich des spitzen Winkels zwischen der entsprechenden abgewinkelten Lasche und der Trägerhülsenwand angeordnet ist. Dadurch wirken die Laschen zusätzlich als Führungshilfe für die Blattfederenden, so daß die Enden der Blattfeder aufgrund der mechanischen Spannung in der Blattfeder zwischen den Laschen und der Trägerhülsenwand klemmend fixiert ist. Die als Blattfeder ausgebildete Andruckfeder der erfindungsgemäßen Lampe weist vorteilhafterweise einen V-förmigen Abschnitt, der durch den Durchbruch in der Trägerhülse greift und zwei U-förmige Abschnitte auf, zwischen denen der V-förmige Abschnitt angeordnet ist, wobei die U-förmigen Abschnitte jeweils einen V-Schenkel des V-förmigen Abschnitts mit einem Ende der Blattfeder verbinden. Mit Hilfe der U-förmigen Abschnitte wird in der Blattfeder vorteilhafterweise eine mechanische Spannung und der Klemmsitz der Blattfeder zwischen den abgewinkelten Laschen der Trägerhülse erzeugt. Der V-förmige Abschnitt, der durch den Durchbruch in der Trägerhülse greift, liegt nach der Montage der Lampe in der als Lampenfassung ausgebildeten Reflektoröffnung des Scheinwerfers federnd an. Der Verbindungsbereich zwischen den beiden Schenkeln des V-förmigen Abschnitts ist vorteilhafterweise abgerundet, um die Kontaktfläche zwischen Andruckfeder und Lampenfassung zu vergrößern und um die Montage der Lampe in der Fassung zu erleichtern. Vorteilhafterweise liegt die Blattfeder in den Übergangsbereichen zwischen dem V-förmigen Abschnitt und den U-förmigen Abschnitten und in den Übergangsbereichen zwischen den U-förmigen Abschnitten und dem jeweiligen Blattfederende an der Innenwand der Trägerhülse an. Dadurch erhöht sich die Stabilität der Befestigung der Andruckfeder.Each end of the leaf spring is advantageously equipped with at least two teeth, between which the respective inwardly angled tab of the carrier sleeve is arranged. The aforementioned teeth allow the entanglement of the respective Leaf spring end with the corresponding tab of the carrier sleeve. advantageously, The angled tabs form a point with the carrier sleeve Angle, each leaf spring end in the range of acute angle between the corresponding angled tab and the carrier sleeve wall is arranged. As a result, the tabs also act as a guide for the leaf spring ends, so that the ends of the leaf spring due to the mechanical stress in the leaf spring is clamped between the tabs and the carrier sleeve wall. The as a leaf spring formed pressure spring of the lamp according to the invention advantageously a V-shaped section through the opening in the carrier sleeve engages and two U-shaped sections, between which the V-shaped section is arranged, wherein the U-shaped portions each have a V-leg of the V-shaped Connect the section to one end of the leaf spring. With the help of the U-shaped Sections in the leaf spring advantageously a mechanical tension and the clamping seat of the leaf spring between the angled tabs of Carrier sleeve produced. The V-shaped section through the breakthrough in the Carrier sleeve engages, is located after mounting the lamp in the lamp socket designed as Reflector opening of the headlamp springy. The connection area between the two legs of the V-shaped section is advantageously rounded to the contact area between the pressure spring and lamp socket too enlarge and to facilitate the mounting of the lamp in the socket. advantageously, lies the leaf spring in the transition areas between the V-shaped Section and the U-shaped sections and in the transitional areas between the U-shaped sections and the respective leaf spring end on the Inner wall of the carrier sleeve. This increases the stability of the attachment the pressure spring.
