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 Claim 1 solved. Particularly advantageous embodiments of the invention are shown 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 enclosed by the lamp bulb Illuminant. The lamp base has a metallic holder part for the Lamp bulb, an annular metallic support sleeve connected to the holder part and a plastic base part provided with the electrical connections of the lamp, in which the carrier sleeve is anchored. To assemble the invention 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 clamp seat in the reflector opening of the lamp holder Headlight is held. The pressure spring lies on the inner wall of the ring-shaped one 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 crossed with one end of the leaf spring, and between which the leaf spring is arranged with a press fit. This causes the pressure spring to open reliable and simple way, that is, without additional fasteners, attached directly to the carrier sleeve. The angled tabs are from the Shaped material of the carrier sleeve. The pressure spring designed as a leaf spring is with a press fit between the two angled tabs that end the leaf spring 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 each Leaf spring end with the corresponding tab of the carrier sleeve. Advantageously the angled tabs form a point with the carrier sleeve Angle, with each leaf spring end in the range of the acute angle between the corresponding angled tab and the support 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 tension in the leaf spring is clamped between the tabs and the carrier sleeve wall. The leaf spring trained pressure spring of the lamp according to the invention advantageously has a V-shaped section through the opening in the carrier sleeve picks up and two U-shaped sections, between which the V-shaped section is arranged, the U-shaped sections each having 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 is advantageously a mechanical tension and the clamp of the leaf spring between the angled tabs of the Carrier sleeve generated. The V-shaped section through the breakthrough in the Carrier sleeve engages after the lamp is installed in the lamp socket Headlight reflector opening resiliently. The connection area between the two legs of the V-shaped section is advantageous rounded to the contact area between the pressure spring and lamp holder enlarge and to facilitate the assembly of the lamp in the socket. Advantageously the leaf spring lies in the transition areas between the V-shaped Section and the U-shaped sections and in the transition 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.
