Description

Die Erfindung bezieht sich auf eine Fahrzeugleuchte mit mehreren Glühlampen, die über Kabel elektrisch leitend mit einem am Leuchtengehäuse angeordneten Mehrfachsteckanschluß verbunden sind, dessen aus Blechstreifen hergestellte Kontaktteile im mittleren Bereich eine Befestigungsvorrichtung aufweisen und an dem einen Endabschnitt als Flackstecker ausgebildet sind, mit denen die Kontaktteile in schlitzförmige Öffnungen des Leuchtengehäuses eingeschoben sind und die mit ihrer Breitenausdehnung in einer oder mehreren Ebenen verlaufend mit Abstand aneinandergereiht sind, während sie an dem anderen Endabschnitt zum abisolierfreien Anschluß der Kabel eine Schneidklemmvorrichtung aufweisen, die aus zwei durch einen Schlitz gebildeten Klemmbacken besteht, die die Isolierung des Kabels bei seinem Eindrücken in den Schlitz durchdringen und einen elektrischen Kontakt zwischen der Kabelseele und dem Kontaktteil herstellen.The invention relates to a vehicle lamp with a plurality of light bulbs, which are electrically conductively connected by cable to a multiple plug connection arranged on the lamp housing, the contact parts made of sheet metal strips in the central region have a fastening device and on which one end section is designed as a flam plug with which the contact parts are inserted into slot-shaped openings in the luminaire housing and are arranged in a row with their width in one or more planes at a distance from one another, while at the other end section for insulation-free connection of the cables they have an insulation displacement device which consists of two clamping jaws formed by a slot, which Penetrate the insulation of the cable when it is pressed into the slot and make electrical contact between the cable core and the contact part.

Fahrzeugleuchten dieser Art weisen für die Glühlampen ein gemeinsames, als Masseleitung dienendes Kabel und mehrere als Stromzuleitungen dienende Kabel auf. Der elektrische Kontakt zwischen den nicht abisolierten Kabeln ist sowohl zu den Glühlampen als auch zu dem Mehrfachsteckanschluß durch als Schneidklemmvorrichtungen hergestellte Kontaktteile gebildet. Die Schneidklemmvorrichtung besteht aus zwei Klemmbacken, die durch einen in das Kontaktteil eingebrachten Schlitz gebildet sind. Durch Eindrücken des Kabels in den Schlitz wird die Isolierung des Kabels zerschnitten, so daß die Klemmbacken mit der Kabelseele kontaktieren. Die aus Blechstreifen hergestellten Kontaktteile des Mehrfachsteckanschlusses verlaufen mit der Breitenausdehnung des als Flachstecker ausgebildeten Endabschnittes in einer oder mehreren Ebenen aneinandergereiht. Die Kontaktteile sind durch die Befestigungsvorrichtung in ihrem mittleren Bereich in der jeweiligen schlitzförmigen Öffnung des Leuchtengehäuses festsetzbar. Der dem Flachstecker gegenüberliegende Endabschnitt der Kontaktteile weist die Schneidklemmvorrichtung auf. Bei sehr schmalen Flachsteckem sind die Kontaktteile an dem die Schneidklemmvorrichtung bildenden Endabschnitt der Kontaktteile breiter als der Flachstecker ausgeführt, so daß es nicht möglich ist, die schmalen Flachstecker dicht nebeneinander anzuordnen, um eine platzsparende Anordnung der Kontaktteile zu erreichen und somit auch den mit dem Mehrfachsteckanschluß zu koppelnden Mehrfachstekker möglichst klein bauen zu können. Aufgabe der Erfindung ist es, den Mehrfachstecker einer im Gattungsbegriff beschriebenen Fahrzeugleuchte derart auszubilden, daß auch bei schmalen, dicht aneinandergereihten Flachsteckem der für die Schneidklemmvorrichtung vorgesehene Endabschnitt der Kontaktteile ausreichend breit sein soll und für die Zuführung der Kabel ausreichend Raum zur Verfügung steht. Diese Aufgabe der Erfindung wird durch folgende Merkmale gelöst:

  • a) die aus Blechstreifen hergestellten Kontaktteile weisen jeweils eine abstehende, abgebogene Fahne auf,
  • b) in die Fahne ist der die Klemmbacken der Schneidklemmvorrichtung schaffende Schlitz in Richtung der Längsausdehnung des Kontaktteils verlaufend eingebracht,
  • c) die in einer Reihe benachbarten Kontaktteile sind um 180° um ihre Längsachse verdreht zueinander angeordnet.
Vehicle lights of this type have a common cable serving as a ground line and several cables serving as power supply lines for the incandescent lamps. The electrical contact between the non-stripped cables is formed both to the incandescent lamps and to the multiple plug connection by contact parts produced as insulation displacement devices. The insulation displacement device consists of two clamping jaws which are formed by a slot made in the contact part. By pressing the cable into the slot, the insulation of the cable is cut so that the clamping jaws contact the cable core. The contact parts of the multiple plug connection made from sheet metal strips run together in one or more planes with the width of the end section designed as a flat plug. The contact parts can be fixed by the fastening device in their central area in the respective slot-shaped opening of the lamp housing. The end section of the contact parts opposite the flat plug has the insulation displacement device. In the case of very narrow tabs, the contact parts on the end section of the contact parts which form the insulation displacement device are made wider than the tab, so that it is not possible to arrange the narrow tabs closely next to one another in order to achieve a space-saving arrangement of the contact parts and thus also with the multiple plug connection to be able to build multiple plugs to be coupled as small as possible. The object of the invention is to design the multiple plug of a vehicle lamp described in the preamble in such a way that the end section of the contact parts provided for the insulation displacement device should be sufficiently wide and there is sufficient space available for the supply of the cables, even in the case of narrow, densely arranged flat plugs. This object of the invention is achieved by the following features:
  • a) the contact parts made from sheet metal strips each have a protruding, bent flag,
  • b) the slot which creates the clamping jaws of the insulation displacement device is introduced into the flag in the direction of the longitudinal extent of the contact part,
  • c) the adjacent contact parts in a row are arranged rotated relative to one another by 180 ° about their longitudinal axis.

Bei einer solchen Lösung baut nicht nur der Mehrfachsteckanschluß durch die platzsparende Anordnung der Kontaktteile zueinander relativ klein, sondern auch der mit dem Mehrfachsteckanschluß zu koppelnde Mehrfachstecker.In such a solution, not only is the multiple plug connection relatively small due to the space-saving arrangement of the contact parts, but also the multiple plug to be coupled with the multiple plug connection.

Weiterhin ist es vorteilhaft, wenn der Schlitz der Schneidklemmvorrichtung zum freien Ende des Rachsteckers hin geöffnet ist und die Biegelinie der abgebogenen Fahne in Richtung der Längsausdehnung des Kontaktteils verläuft. Hierbei ist es zweckmäßig, wenn die Fahne in einem rechten Winkel zum Flachstecker abgebogen ist. Mit einem solchen Kontaktteil kann gleichzeitig mit dem Einschieben des Flachsteckers in die schlitzförmige Öffnung des Leuchtengehäuses die Isolierung des Kabels zerschnitten werden.Furthermore, it is advantageous if the slot of the insulation displacement device is open towards the free end of the throat plug and the bending line of the bent flag runs in the direction of the longitudinal extent of the contact part. It is useful if the flag is bent at a right angle to the tab. With such a contact part, the insulation of the cable can be cut simultaneously with the insertion of the tab into the slot-shaped opening of the lamp housing.

Ein weiterer Vorteil ist es, wenn die abgewinkelte Fahne der Kontaktteile jeweils von zwei parallel zueinander verlaufenden und entgegengesetzt der Einschubrichtung der Kontaktteile sich erstreckenden wandungsförmigen Vorsprüngen geführt ist, die einen entgegen der Einschubrichtung des Kontaktteils sich öffenden Längsschlitz aufweisen, in dessen Grund das Kabel anliegt, dessen Kabelseele nach dem Zerschneiden der Isolierung durch die Klemmbacken mit dem Kontaktteil kontaktiert und mindestens ein Längsschlitz der beiden wandungsförmigen Vorsprünge an seinem Grund so schmal ausgeführt ist, daß er das eingelegte Kabel zwischen sich einklemmt. Bei dieser Ausführungsform sind die Kabel bis zum Einschieben der Kontaktteile in die schlitzförmigen Öffnungen des Leuchtengehäuses sicher in den Längsschlitzen der wandungsförmigen Vorsprünge gehalten.It is a further advantage if the angled flag of the contact parts is guided by two wall-shaped projections which run parallel to one another and extend counter to the insertion direction of the contact parts and which have a longitudinal slot which opens counter to the insertion direction of the contact part and in the base of which the cable rests. the cable core contacted after cutting the insulation through the jaws with the contact part and at least one longitudinal slot of the two wall-shaped projections is so narrow at its bottom that it clamps the inserted cable between them. In this embodiment, the cables are securely held in the longitudinal slots of the wall-shaped projections until the contact parts are inserted into the slot-shaped openings in the lamp housing.

Ferner ist es vorteilhaft, wenn die beiden wandungsförmigen Vorsprünge an einer der beiden schmalen Längsseiten durch eine dritte Wandung untereinander verbunden sind und diese dritte Wandung ebenfalls eine Begrenzung für die Kontaktfahne bildet. Dadurch wird beim Zerschneiden der Isolierung des Kabels ein unerwünschtes Auffedern und eine Deformierung der beiden Klemmbacken verhindert.It is also advantageous if the two wall-shaped projections are connected to one another on one of the two narrow longitudinal sides by a third wall and this third wall also forms a boundary for the contact tab. This prevents unwanted springing open and deformation of the two clamping jaws when the cable insulation is cut.

Ebenfalls ist es vorteilhaft, wenn der Flachstecker des Kontaktteils durch Falten des Blechstreifens gedoppelt ist und der gefaltete Abschnitt eine zur Schneidklemmvorrichtung weisende Rastnase aufweist, die nach dem Einsetzen des Kontaktteils den Rand der schlitzförmigen Öffnung des Leuchtengehäuses hintergreift. Dadurch sind die Kontaktteile nach dem Einschieben in die schlitzförmigen Öffnungen des Leuchtengehäuses selbstrastend festgesetzt.It is also advantageous if the tab of the contact part is doubled by folding the sheet metal strip and the folded section has a locking lug pointing towards the insulation displacement device, which engages behind the edge of the slot-shaped opening of the lamp housing after the contact part has been inserted. As a result, the contact parts are self-locking after being inserted into the slot-shaped openings in the lamp housing.

Ein weiterer Vorteil ist es, wenn der gedoppelte Flachstecker durch Falten der beiden seitlichen Abschnitte des Kontaktteils um zwei parallel zueinander und in Richtung der Längsausdehnung des Ftachsteckers verlaufenden Biegelinien hergestellt ist. Bei einer solchen Lösung können die Biegelinien der Faltungen und die Biegelinie der abgebogenen Fahne quer zur Walzrichtung verlaufen, so daß das Kontaktteil eine hohe Festigkeit aufweist.Another advantage is when the double Flat plug is produced by folding the two lateral sections of the contact part by two bending lines running parallel to one another and in the direction of the longitudinal extension of the flat plug. With such a solution, the bending lines of the folds and the bending line of the bent flag can run transversely to the rolling direction, so that the contact part has a high strength.

Die Zeichung zeigt in einer Teilansicht das Leuchtengehäuse 1 einer Fahrzeugleuchte, deren nichtdargestellte Glühlampen über Kabel 2 mit einem Mehrfachsteckanschluß elektrisch leitend verbunden sind. Der Mehrfachsteckanschluß besteht aus mehreren aus Blechstreifen hergestellten Kontaktteilen 3, die an einem Endabschnitt einen Flachstecker 4 und mit dem anderen Endabschnitt eine Klemmschneidvorrichtung 5 aufweisen. Die Flachstecker 4 sind durch Falten der seitlichen Abschnitte 6 des Kontaktteils und zwei parallel zueinander und in Richtung der Längsausdehnung des Flachsteckers 4 verlaufenden Biegelinien gedoppelt. Die gefalteten Abschnitte 6 bilden eine zur Schneidklemmvorrichtung 5 weisende, nach außen gebogene, als Rastnase 7 dienende Zunge. Der andere Ehdabschnitt des Kontaktteils 3 weist eine abstehende Fahne 8 auf, die im rechten Winkel zum Flachstecker abgebogen ist In die Fahne 8 ist der die Klemmbacken der Schneidklemmvorrichtung 5 schaffende Schlitz 15 eingebracht. Der Schlitz 15 verläuft in Richtung der Längsausdehnung des Kontaktteils 3 und ist zum freien Ende des Flachsteckers 4 hin geöffnet. Die Biegelinie der abgebogenen Fahne 8 verläuft in Richtung der Längsausdehnung des Kontaktteils 3. Die Kontaktteile 3 sind mit ihren Flachsteckem 4 in schlitzförmige Öffnungen 9 des Leuchtengehäuses 1 einschiebbar. Die schlitzförmigen Öffnungen 9 sind entsprechend dem Querschnitt der Flachstecker 4 ausgebildet und sind in ihrer Längsrichtung dicht aneinandergereiht. Die Kontaktteile 3 sind mit ihren Flachsteckem 4 abwechselnd um 180° um ihre Längsachse verdreht in den schlitzförmigen Öffnungen 9 des Leuchtengehäuses angeordnet. Beim Einschieben der Flachstecker 4 in die schlitzförmigen Öffnungen 9 sind die Fahnen 8 zwischen zwei parallel zueinander verlaufenden wandungsförmigen Vorsprüngen 10 des Leuchtengehäuses 1 geführt, und die Stimfläche der Fahne 8 gleitet an einer die beiden Wandungen 10 verbindenden dritten Wandung 11 entlang. Die Wandungen 10 weisen entgegen der Einschubrichtung des Kontaktteils sich öffnende Längsschlitze 12 auf. Die Längsschlitze 12 sind am Grund so schmal ausgeführt, daß sie ein eingelegtes Kabel 2 zwischen sich einklemmen. Beim Einschieben des Kontaktteils 3 in die schlitzförmige Öffnung 9 des Leuchtengehäuses 1 zerschneiden die Klemmbacken der Schneidklemmvorrichtung 5 die Isolierung des Kabels 2 und kontaktieren in der Endstellung des Kontaktteils 3 mit der Seele des Kabels 2. Gleichzeitig hintergreift in der Endstellung des Kontaktteils 3 die Rastnase 7 den Rand einer schlitzförmigen Öffnung 9 des Leuchtengehäuses 1. Die Glühlampenfassungen 12 und die mit dem Mittelpol der Glühlampen kontaktierenden Kontaktstreifen 13 weisen eine Schneidklemmvorrichtung 14 für Kabel auf.The drawing shows a partial view of the lamp housing 1 of a vehicle lamp, the light bulbs, not shown, are electrically conductively connected via cable 2 to a multiple plug connection. The multiple plug connection consists of a plurality of contact parts 3 made of sheet metal strips, which have a flat plug 4 at one end section and a clamping cutting device 5 with the other end section. The flat connectors 4 are doubled by folding the lateral sections 6 of the contact part and two bending lines running parallel to one another and in the direction of the longitudinal extension of the flat connector 4. The folded sections 6 form a tongue which points towards the insulation displacement device 5 and is bent outwards and serves as a latching lug 7. The other end portion of the contact part 3 has a projecting flag 8, which is bent at right angles to the flat plug. The slot 15, which creates the clamping jaws of the insulation displacement device 5, is introduced into the flag 8. The slot 15 runs in the direction of the longitudinal extent of the contact part 3 and is open towards the free end of the tab 4. The bending line of the bent flag 8 runs in the direction of the longitudinal extent of the contact part 3. The contact parts 3 can be inserted with their tabs 4 into slot-shaped openings 9 of the lamp housing 1. The slot-shaped openings 9 are designed in accordance with the cross section of the flat plug 4 and are closely lined up in their longitudinal direction. The contact parts 3 are arranged with their tabs 4 alternately rotated by 180 ° about their longitudinal axis in the slot-shaped openings 9 of the lamp housing. When the flat plug 4 is inserted into the slot-shaped openings 9, the flags 8 are guided between two parallel wall-shaped projections 10 of the lamp housing 1, and the end face of the flag 8 slides along a third wall 11 connecting the two walls 10. The walls 10 have longitudinal slots 12 that open against the direction of insertion of the contact part. The longitudinal slots 12 are so narrow at the bottom that they clamp an inserted cable 2 between them. When the contact part 3 is inserted into the slot-shaped opening 9 of the lamp housing 1, the clamping jaws of the insulation displacement device 5 cut the insulation of the cable 2 and make contact with the core of the cable 2 in the end position of the contact part 3 the edge of a slot-shaped opening 9 of the luminaire housing 1. The light bulb sockets 12 and the contact strips 13 contacting the center pole of the light bulbs have an insulation displacement device 14 for cables.
