Description

Die Erfindung betrifft einen Kraftfahrzeug-Zünd- oder Glühanlaßschalter nach dem Oberbegriff des Anspruches 1.The invention relates to a motor vehicle ignition or glow starter switch according to the preamble of claim 1.

Ein derartiger bekannter Kraftfahrzeug-Zündanlaßschalter (DE-AS 25 55 110) weist an seinem Sockelteil einen zentralen Mittelkontakt und mehrere Randkontakte auf, während der Mitnehmer oder das Schaltrad ein Überbrückungselement hält, das mit einem Kontaktkopf eines auf die Schalterachse ausgerichteten Doppelkontaktes unter Vorspannung ständig leitend mit dem Mittelkontakt verbunden ist und dessen stromführender Kontaktfinger die Randkontakte überstreicht. Der Mitnehmer oder das Schaltrad hält außerdem eine Schaltbrücke, deren Schaltarm auf einem Schaltprofil aufliegt, deren zentraler Mittelkontakt dadurch gegenüber dem anderen Kontaktkopf des Doppelkontaktes abhebbar ist und deren Kontaktschenkel ebenfalls stromführend über die jeweiligen Randkontakte gleiten.Such a known motor vehicle ignition switch (DE-AS 25 55 110) has at its base part a central center contact and several edge contacts, while the driver or the switching wheel holds a bridging element which is constantly conductive with a contact head of a double contact aligned with the switch axis under bias is connected to the center contact and its current-carrying contact finger sweeps over the edge contacts. The driver or the switching wheel also holds a switching bridge, the switching arm of which rests on a switching profile, the central center contact of which can thus be lifted off from the other contact head of the double contact, and the contact legs of which also slide in a current-carrying manner over the respective edge contacts.

Der bekannte Kraftfahrzeug-ZündanlaBschalter geht von bekannten Schaltern (DE-GM 6 801 832 und DE-GM 73 10 447) mit einer einzigen abhebenden Schaltbrücke aus.The known motor vehicle ignition switch is based on known switches (DE-GM 6 801 832 and DE-GM 73 10 447) with a single lifting switching bridge.

Um einen derartigen bekannten Schalter mit einer weiteren abhebenden Schaltbrücke auszubilden, wurde in einer Verdoppelung des bekannten Schaltprinzips am Mitnehmer oder Schaltrad eine weitere Schaltbrücke angeordnet, die mit einem Steg zwischen dem Mittelkontakt und dem einen Kontaktkopf des Doppelkontaktes liegt und mit einem Schaltarm auf einem weiteren Schaltprofil gleitet, wobei ein Kontaktbelag dieser weiteren Schaltbrücke als Abhebekontakt mit einem Gegenkontakt am Sockelteil zusammenwirkt.In order to form such a known switch with a further lifting switching bridge, a further switching bridge was arranged in a doubling of the known switching principle on the driver or ratchet wheel, with a bridge between the center contact and the one contact head of the Double contact is located and slides with a switching arm on a further switching profile, a contact coating of this further switching bridge cooperating as a lifting contact with a mating contact on the base part.

Bei dem bekannten Schalter erfolgt also die Stromzuführung über den zentralen Mittelkontakt, und alle der Stromzufuhr dienenden Kontakte sind somit zwangsläufig zentral auf die Mittelachse des Schalters ausgerichtet.In the case of the known switch, the current is supplied via the central center contact, and all the contacts serving to supply the current are therefore necessarily aligned centrally with the center axis of the switch.

Schwierigkeiten können sich bei einer solchen zentralen Anordnung mit mehreren Mittelkontakten entlang der Schalterdrehachse dadurch ergeben, daß für eine einwandfreie Kontaktgabe und -unterbrechung jeder der vorhandenen Schaltkontaktköpfe einen ausreichend lang bemessenen Schaltweg haben muß, um eine vorzeitige oder völlig unbeabsichtigte Kontaktgabe zu vermeiden. Bei einem größeren Abstand zwischen den einzelnen Schaltkontaktköpfen ergeben sich aber wiederum Schwierigkeiten in der Steuerung der Kontaktarme durch die am Schaltergehäuse konzentrisch zur Schalterdrehachse angeordneten Kurven- oder Nockenbahnen, deren Kurvenverlauf nur ein bestimmtes Maß an Steigungen zwischen den einzelnen Raststellen des Schalters zuläßt, das durch zu große Schaltwege leicht in unzulässiger Weise überschritten werden kann. Ein derartiger bekannter Schalter muß außerdem eine verhältnismäßig große axiale Länge haben, was sich wiederum nachteilig auf die Ausbildung der Rastkurven zwischen Mitnehmer oder Schaltrad und Schaltergehäuse auswirkt, in denen üblicherweise am Mitnehmer durch Federdruck belastete Raststifte entlanggleiten.Difficulties can arise in such a central arrangement with a plurality of center contacts along the axis of rotation of the switch in that each switch contact head must have a sufficiently long switching path to ensure correct contacting and interruption in order to avoid premature or completely unintentional contacting. With a larger distance between the individual switch contact heads, however, difficulties arise in the control of the contact arms due to the curved or cam tracks arranged concentrically to the switch axis of rotation on the switch housing, the curve profile of which only allows a certain amount of incline between the individual rest points of the switch, which is due to large switching distances can easily be exceeded in an impermissible manner. Such a known switch must also have a relatively large axial length, which in turn has a disadvantageous effect on the formation of the locking curves between the driver or ratchet and the switch housing, in which locking pins loaded by spring pressure usually slide along the driver.

Da die Nocken- oder Kurvenbahnen für die Steuerung der Kontaktarme am Umfang des Sockelteiles oder des Schaltergehäuses nur eine bestimmte begrenzte Länge haben können, ergeben sich auch Schwierigkeiten, wenn eine größere Anzahl von Verbrauchern in kleineren Winkelabständen nacheinander geschaltet werden soll.Since the cam tracks or cam tracks for the control of the contact arms on the circumference of the base part or the switch housing can only have a certain limited length, difficulties also arise when a larger number of consumers are to be connected in succession at smaller angular intervals.

Der Erfindung liegt die Aufgabe zugrunde, einen Kraftfahrzeug-Zünd- oder -Glühanlaßschalter nach dem Oberbegriff des Anspruches 1 so auszubilden, daß trotz einer Verringerung der axialen Baulänge des Schalters eine größere Anzahl von Schaltstellungen in kleineren Winkelabständen als bisher verwirklicht werden kann, ohne daß dadurch die Funktionssicherheit und die Zuverlässigkeit des Schalters nachteilig beeinflußt wird.The invention has for its object to provide a motor vehicle ignition or Glühanlaßschalter according to the preamble of claim 1 so that despite a reduction in the axial length of the switch, a larger number of switching positions can be realized at smaller angular intervals than before, without this the functional reliability and reliability of the switch is adversely affected.

Diese Aufgabe findet ihre Lösung gemäß der Erfindung im wesentlichen dadurch, daß die Kontaktarme im Bereich der Schalterdrehachse etwa U-förmig gegeneinander verkröpft und in einer gemeinsamen Ebene über Kreuz angeordnet sind, und daß den Kontaktköpfen mindestens ein konzentrisch zur Schalterdrehachse angeordneter Kontaktring als Gegenkontakt zugeordnet ist.This object is achieved according to the invention essentially in that the contact arms are cranked in a U-shaped manner in the area of the switch axis of rotation and arranged in a common plane in a cross manner, and in that the contact heads are assigned at least one contact ring arranged concentrically to the switch axis of rotation as a counter contact .

Durch die erfindungsgemäße Ausbildung des Schalters mit gekröpften, in einer gemeinsamen Ebene über Kreuz angeordneten Kontaktarmen mit außerhalb der Schalterdrehachse angeordneten Kontaktköpfen und mit mindestens einem konzentrisch zur Schalterdrehachse angeordneten Kontaktring ergibt sich der Vorteil einer vielseitigeren Schalterbauweise. An dem Kontaktring können mehrere Kontaktarme gleichzeitig.oder unabhängig voneinander geschaltet werden. Da die Kontaktarme keinen Mittelkontakt haben, können sie entlang der Schalterdrehachse dichter beieinander angeordnet sein, ohne daß die Gefahr von Fehlschaltungen besteht.The inventive design of the switch with cranked contact arms arranged crosswise in a common plane with contact heads arranged outside the axis of rotation of the switch and with at least one contact ring arranged concentrically to the axis of rotation of the switch results in the advantage of a more versatile switch design. Several contact arms can be switched simultaneously or independently on the contact ring. Since the contact arms have no center contact, they can be arranged closer together along the switch axis of rotation without the risk of incorrect switching.

Die Kontaktarme können auch eine größere radiale Länge als bei der bekannten Schalterkonstruktion haben, wodurch sich eine größere Umfangslänge der Nocken- oder Kurvenbahnen am Schaltergehäuse ergibt, was wiederum eine häufigere Schaltfolge in einer Vielzahl von kleineren Winkelabständen zwischen den einzelnen Schaltungen ermöglicht.The contact arms can also have a greater radial length than in the known switch construction, which results in a greater circumferential length of the cam or cam tracks on the switch housing, which in turn enables a more frequent switching sequence in a large number of smaller angular distances between the individual circuits.

Vorteilhafte Weiterbildungen der Erfindung sind in den Ansprüchen 2 bis 9 enthalten, wobei ein hohes Rastmoment dadurch erreicht werden kann, daß am Sockelteil oder Deckelteil des Schaltergehäuses mindestens zwei Rastkurven angeordnet sind, denen am Mitnehmer oder Schaltrad jeweils mindestens ein federbelasteter Bolzen zugeordnet ist. Die Anordnung von Rastkurven und Rastbolzen kann dabei auch so getroffen werden, daß die Rastkurven am Mitnehmer oder Schaltrad und die federbelasteten Rastbolzen am Sockelteil oder Deckelteil des Schaltergehäuses entsprechend angeordnet sind. Mit den Rastkurven und den zugehörigen zwei oder mehreren Rastbolzen kann auch eine bessere technische Herstellung der Rastungen für die Vielzahl von möglichen Schaltstellungen erreicht werden ebenso wie die Gewähr einer einwandfreien Funktion.Advantageous developments of the invention are contained in claims 2 to 9, wherein a high cogging torque can be achieved in that at least two locking curves are arranged on the base part or cover part of the switch housing, each of which is assigned at least one spring-loaded bolt on the driver or ratchet wheel. The arrangement of locking curves and locking bolts can also be made so that the locking curves on the driver or ratchet and the spring-loaded locking bolts on the base part or cover part of the switch housing are arranged accordingly. With the latching curves and the associated two or more latching bolts, a better technical manufacture of the latches for the multitude of possible switching positions can also be achieved, as can the guarantee of perfect functioning.

Bei dem gezeigten Schalter handelt es sich um einen Zünd-oder -Glühanlaßschalter für Kraftfahrzeuge. Derartige Schalter werden zum unabhängigen Schalten mehrerer Verbraucher benötigt.The switch shown is an ignition or glow starter switch for motor vehicles. Such switches are required for the independent switching of several consumers.

Der Schalter besteht aus einem Sockelteil 1 mit radial nach außen gerichteten Befestigungsaugen 2, das an seiner Oberseite durch ein Deckelteil 3 mit einer zentralen Drehlagerung 4 für einen Mitnehmer oder ein Schaltrad 5 ausgebildet ist.The switch consists of a base part 1 with radially outwardly directed fastening eyes 2, which is formed on its upper side by a cover part 3 with a central rotary bearing 4 for a driver or a switching wheel 5.

Vom Sockelteil 1 ragen mehrere Anschlußklemmen 6, 7, 8 nach unten, von denen eine (6) mit einem konzentrisch zur Schalterdrehachse 9 angeordneten Kontaktring 10 verbunden ist, während die anderen Anschlußklemmen 7, 8 und weitere nicht gezeigte Klemmen zu entsprechenden Verbraucherkontakten 11, 12, 13, 14, 15 gehören, die an der Oberseite des Sockelteiles 1 rings um den Kontaktringo@ verteilt angeordnet sind (Fig. 2).A plurality of connection terminals 6, 7, 8 project downward from the base part 1, one (6) of which is connected to a contact ring 10 arranged concentrically to the switch axis of rotation 9, while the other connection terminals 7, 8 and further terminals (not shown) lead to corresponding consumer contacts 11, 12 , 13, 14, 15 belong, which are arranged on the top of the base part 1 around the contact ring @ distributed (Fig. 2).

Der Mitnehmer oder das Schaltrad 5 besitzt eine obere Eingriffsöffnung 16 für einen Schließzylinder oder dergleichen und kann im Schaltergehäuse entgegen der Wirkung einer Schrauben-Drehfeder 17 gedreht werden.The driver or the switching wheel 5 has an upper engagement opening 16 for a lock cylinder or the like and can be rotated in the switch housing against the action of a helical torsion spring 17.

An der Oberseite des Mitnehmers 5 befinden sich zwei federbelastete Raststifte 18, 19, die in zwei an der Unterseite des Deckelteils 3 konzentrisch zur Schalterdrehachse 9 angeordnete Rastkurven 20, 21 (Fig. 1 und 2) mit mehreren Rastvertiefungen in den vorgesehenen Schaltstellungen unabhängig voneinander eingreifen und den Mitnehmer oder das Schaltrad 5 in der jeweils gewünschten Schaltstellung festhalten. Jeder der beiden Raststifte 18, 19 steht unter dem Druck einer in der Zeichnung nicht gezeigten Schraubenfeder.On the top of the driver 5 there are two spring-loaded locking pins 18, 19, which engage in two locking curves 20, 21 (FIGS. 1 and 2) arranged on the underside of the cover part 3 concentrically to the switch axis of rotation 9 with several locking recesses in the intended switching positions independently of one another and hold the carrier or the switching wheel 5 in the desired switching position. Each of the two locking pins 18, 19 is under the pressure of a coil spring, not shown in the drawing.

An der Unterseite des Mitnehmers oder Schaltrades 5 sind zwei im Bereich der Schalterdrehachse 9 etwa U-förmig gegeneinander verkröpfte Kontaktarme 22, 23 über Kreuz angeordnet, von denen jeder unter dem Druck einer Schraubendruckfeder 24, 25 steht. Das in Fig. 3 und 4 der Zeichnung rechts liegende Ende 22a, 23a jedes der beiden Kontaktarme 22, 23 gleitet über die Verbraucherkontakte 11, 12, 13, 14, 15 am Sockelteil 1 hinweg, während das mit einem endseitigen Steuerstück 22b, 23b ausgebildete gegenüberliegende Ende auf einer eigenen Kurvenbahn 22', 23' am Sockelteil 1 geführt ist. Die Kurvenbahnen 22', 23' verlaufen außerhalb der Verbraucherkontakte 11, 12, 13, 14, 15 konzentrisch zur Schalterdrehachse 9 und sind stufenweise gegeneinander versetzt.On the underside of the driver or ratchet wheel 5, two contact arms 22, 23 which are cranked against one another in a U-shaped manner in the region of the switch axis of rotation 9 are arranged crosswise, each of which is under the pressure of a helical compression spring 24, 25. 3 and 4 of the drawing, the right end 22a, 23a of each of the two contact arms 22, 23 slides over the consumer contacts 11, 12, 13, 14, 15 on the base part 1, while that formed with an end control piece 22b, 23b opposite end is guided on its own cam track 22 ', 23' on the base part 1. The cam tracks 22 ', 23' run outside the consumer contacts 11, 12, 13, 14, 15 concentrically to the switch axis of rotation 9 and are gradually offset from one another.

Oberhalb des mit einem geeigneten Kontaktmaterial 10a versehenen Kontaktringes 10 am Sockelteil 1 weist jeder der beiden Kontaktarme 22 23 einen Kontaktkopf 22c, 23c auf, der bei einer Betätigung des Schalters entsprechend dem Verlauf der außenliegenden Kurvenbahnen 22', 23' geschaltet wird. Der Kontaktkopf 22c, 23c ist an jedem.Kontaktarm 22, 23 gegenüber der Schalterdrehachse 9 radial nach außen versetzt. Beide Kontaktarme 22, 23 sind über Kreuz angeordnet (Fig. 3 bis 5), und jedem Kontaktarm ist ein Haltekontakt 26, 27 zugeordnet, die auf gleichem Niveau mit den Arbeits-und den Verbraucherkontakten 11, 12, 13, 14, 15 arbeiten, jedoch mittels zusätzlicher Nockenbahnen 28, von denen in Fig. 2 lediglich eine Nockenbahn gezeigt ist, vom Kontaktring 10 abgehoben werden können.Above the contact ring 10 provided with a suitable contact material 10a on the base part 1, each of the two contact arms 22 23 has a contact head 22c, 23c, which is switched when the switch is actuated in accordance with the course of the external cam tracks 22 ', 23'. The contact head 22c, 23c is offset radially outwards on each contact arm 22, 23 with respect to the switch axis of rotation 9. Both contact arms 22, 23 are arranged crosswise (FIGS. 3 to 5), and each contact arm is assigned a holding contact 26, 27, which work on the same level with the working and consumer contacts 11, 12, 13, 14, 15, however, by means of additional cam tracks 28, of which only one cam track is shown in FIG. 2, can be lifted off the contact ring 10.

Auch die zusätzlichen Nockenbahnen 28 für die Haltekontakte 26, 27 sind konzentrisch um die Schalterdrehachse 9, jedoch radial innerhalb der Verbraucherkontakte 11 bis 15 angeordnet. Der Kontaktring 10 und die Kontaktköpfe 22c, 23c sind zweckmäßig silberplattiert, können jedoch mit einem anderen geeigneten Kontaktmaterial beschichtet sein, wenn dieses nur so ausgebildet ist, daß es den hohen Beanspruchungen, denen es bei Kraftfahrzeug-Zünd- und -Glühanlaßschaltern ausgesetzt ist, hinreichend standhält.The additional cam tracks 28 for the holding contacts 26, 27 are also arranged concentrically around the switch axis of rotation 9, but radially within the consumer contacts 11 to 15. The contact ring 10 and the contact heads 22c, 23c are expediently silver-plated, but can be coated with another suitable contact material if this is only designed so that it suffices the high stresses to which it is subjected in motor vehicle ignition and glow starter switches withstands.

Die Haltekontakte 26, 27 sind entweder federbelastet oder bestehen aus einem federnden Material und können entweder auf dem Kontaktmaterial 10a des Kontaktringes 10 oder radial daneben laufen, was im allgemeinen zu bevorzugen ist, um unerwünschte Beschädigungen des Kontaktmaterials durch die darüber hinweggleitenden Haltekontakte zu vermeiden.The holding contacts 26, 27 are either spring-loaded or consist of a resilient material and can either run on the contact material 10a of the contact ring 10 or radially next to it, which is generally preferred in order to avoid undesirable damage to the contact material by the holding contacts sliding over it.

Ebenso wie die Rastkurven 20, 21 für die Raststifte 18, 19 bei der gezeigten Ausführungsform an der Innenseite des Deckelteils 3 des Schaltergehäuses angeordnet sind, können sich die beiden Kurven auch am Boden- bzw. Sockelteil 1 befinden. Außerdem ist es aber auch möglich, die Rastkurven am Mitnehmer auszubilden und die zugehörigen Raststifte entweder am Boden oder Deckelteil des Schaltergehäuses anzuordnen. Statt eines gemeinsamen Kontaktringes 10 können für die beiden Kontaktarme 22, 23 auch zwei getrennte Kontaktringe oder eine zusätzliche Kontaktbrücke vorgesehen sein.Just as the locking curves 20, 21 for the locking pins 18, 19 are arranged in the embodiment shown on the inside of the cover part 3 of the switch housing, the two curves can also be located on the base or base part 1. In addition, it is also possible to form the locking curves on the driver and to arrange the associated locking pins either on the bottom or cover part of the switch housing. Instead of a common contact ring 10, two separate contact rings or an additional contact bridge can also be provided for the two contact arms 22, 23.
