The sleeve-like section 52 is against the arrow direction 31 on the section 38 pushed on and is like this on average across the direction of assembly 31 rectangular. The sleeve-like section 52 has a slot 56 so that it is transverse to the mounting direction 31 is elastically expandable. There is also two opposite side walls of the sleeve-like section 52 each have an opening 58. Of two opposite sides of section 38 of FIG Envelope 36 protrudes a projection 60 to the outside is beveled towards the light source 14. From the sleeve-like section 52 continues to point the way from the light source 14 a contact tab 62 to which the line 51 is connected is. The ends of the sleeve-like portion 52 are bent outward to a slightly pushing on the section 38 of the casing 36 enable.

Die Kontaktarme 54 in ihrem über den Abschnitt 38 der Umhüllung 36 hinausragenden Bereich zueinander hin gebogen und ihre Enden sind u-förmig gebogen, wobei der Scheitel der U-Form der beiden Kontaktarme 54 einander zugewandt sind. Die Kontaktarme 54 sind in ihrem federnden Bereich mit einer Sicke 55 versehen, um ihre Biegesteifigkeit zu erhöhen. Der Abstand zwischen den Enden der Kontaktarme 54 zueinander ist etwas geringer als der Durchmesser des zylinderförmigen Sockelabschnitts 22 der Lichtquelle 14.The contact arms 54 in their over section 38 of the sheath 36 protruding area bent towards each other and their ends are bent into a U shape, with the apex of the U shape of the two Contact arms 54 are facing each other. The contact arms 54 are provided in its resilient area with a bead 55 to your Increase bending stiffness. The distance between the ends of the Contact arms 54 to each other is slightly less than that Diameter of the cylindrical base portion 22 of the Light source 14.

Zur Montage des Massenkontaktelements 50 wird dessen hülsenartiger Abschnitt 52 entgegen Pfeilrichtung 31 auf den Abschnitt 38 der Umhüllung aufgeschoben. Die Breite des Abschnitts 38 der Umhüllung 36 im Bereich der beiden die Vorsprünge 60 aufweisenden Seiten ist etwas größer als der Querschnitt des hülsenartigen Abschnitts 52, so daß dieser etwas aufgeweitet wird, was durch dessen Schlitz 56 ermöglicht ist. In der Endlage des Massekontaktelements 50 tritt jeweils ein Vorsprung 60 durch eine Öffnung 58 im hülsenartigen Abschnitt 52 hindurch, wodurch eine rastartige Befestigung des Kontaktelements 50 auf dem Abschnitt 38 erreicht ist.To assemble the mass contact element 50, its sleeve-like Section 52 against arrow direction 31 on the section 38 of the casing pushed on. The width of section 38 of the Envelope 36 in the region of the two having the projections 60 Is slightly larger than the cross section of the sleeve-like section 52, so that this is somewhat expanded becomes what is made possible by its slot 56. In the end position of the ground contact element 50 occurs in each case a projection 60 through an opening 58 in the sleeve-like section 52, whereby a latch-like attachment of the contact element 50 the section 38 is reached.

Bei der Montage des Steckerteils 30 auf die Lichtquelle 14 werden die Kontaktarme 54 des Massekontaktelements 50 auseinander gebogen, wenn diese mit ihren Enden auf den Isolierabschnitt 24 des Sockels der Lichtquelle 14 treffen. In der Endlage des Steckerteils 30 liegen die Kontaktarme 54 mit ihren Enden radial am zylinderförmigen Sockelabschnitt 22 der Lichtquelle 14 unter Vorspannung an, so daß durch das Steckerteil 30 zugleich die plusseitige Verbindung als auch die Masseverbindung der Lichtquelle 14 hergestellt ist.When mounting the connector part 30 on the light source 14 the contact arms 54 of the ground contact element 50 apart bent when these have their ends on the insulating section 24 of the base of the light source 14. In the end position of the Plug part 30, the contact arms 54 are radial with their ends on the cylindrical base section 22 of the light source 14 under tension, so that through the plug part 30 at the same time the plus side connection as well as the ground connection of the Light source 14 is made.

Der Abstand zwischen den Enden der Kontaktarme 54 und dem zur Lichtquelle 14 weisenden Ende der Steckhülse 32und der Querschnitt der Öffnung 44, durch die der Kontaktstift 20 hindurchtritt sind dabei so aufeinander abgestimmt, daß der Kontaktstift 20 nicht infolge einer Schrägstellung zugleich an den Enden der Kontaktarme 54 und an der Steckhülse 32 zur Anlage kommen kann, wodurch ein Kurzschluß entstünde. Hierbei ist auch der Abstand zwischen dem der Lichtquelle 14 zugewandten Ende der Steckhülse 32 und der Wandung 42 zu berücksichtigen. Eine Schrägstellung des Kontaktstifts 20 in einer die beiden Kontaktarme 54 enthaltenden Ebene ist dadurch begrenzt, daß dieser nur mit geringem Spiel durch die Öffnung 44 hindurchtritt. Je geringer der Abstand der Enden der Kontaktarme 54 von der Wandung 42 der Umhüllung 36 ist, desto stärker kann der Kontaktstift 20 schräg gestellt werden, ohne zugleich an der Steckhülse 32 und den Enden der Kontaktarme 54 zur Anlage zu kommen. Umgekehrt muß die Schrägstellung des Kontaktstifts 20 um so enger begrenzt werden, je größer der Abstand der Enden der Kontaktarme 54 von der Wandung 42 der Umhüllung ist.The distance between the ends of the contact arms 54 and the Light source 14 facing end of the socket 32 and the cross section the opening 44 through which the contact pin 20 passes are matched so that the contact pin 20 not due to an inclination at the same time Ends of the contact arms 54 and on the socket 32 for contact can come, which would result in a short circuit. Here is also the distance between the end facing the light source 14 the socket 32 and the wall 42 to be taken into account. A Inclination of the contact pin 20 in one of the two Level containing contact arms 54 is limited in that it passes through the opening 44 with little play. The smaller the distance of the ends of the contact arms 54 from the wall 42 of the casing 36, the stronger the Contact pin 20 can be inclined without at the same time Plug sleeve 32 and the ends of the contact arms 54 to the system come. Conversely, the inclination of the contact pin 20th the closer the distance between the ends the contact arms 54 is from the wall 42 of the envelope.

Abweichend zu der vorstehend beschriebenen Ausführung können die Kontaktarme 54 des Massekontaktelements 50 auch so ausgebildet sein, daß sie am Sockelteller 18 der Lichtquelle 14 zur Anlage kommen. Außerdem kann auch nur ein Kontaktarm 54 vorgesehen werden oder mehr als zwei Kontaktarme 54. Schließlich kann die Lichtquelle 14 auch ein anderes Kontaktelement als den Kontaktstift 20 aufweisen, beispielsweise eine Steckhülse, wobei dann das Steckerteil 30 ein zum Zusammenwirken mit dem Kontaktelement ausgebildetes Steckelement aufweistDeviating from the embodiment described above can the contact arms 54 of the ground contact element 50 are also designed in this way be that they on the base plate 18 of the light source 14 Plant come. In addition, only one contact arm 54 can be used be provided or more than two contact arms 54. Finally the light source 14 can also be another contact element have as the contact pin 20, for example a plug-in sleeve, then the plug part 30 a to cooperate with the contact element formed plug element

Die vorstehend beschriebene elektrische Kontaktierung einer Lichtquelle ist nicht auf die Anwendung bei einer H1-Glühlampe beschränkt, sondern kann allgemein bei Lichtquellen angewandt werden, bei denen nur für die plusseitige Verbindung ein Anschlußkontakt vorgesehen ist und die Masseverbindung über den Sockel der Lichtquelle erfolgt.The electrical contacting described above Light source is not for use on an H1 bulb limited, but can generally be applied to light sources with a connection contact only for the plus-side connection is provided and the ground connection via the Base of the light source is done.
