Abstract

In door switches for vehicles, the operating movement in general corresponds directly to the switching movement, that is to say a large operating movement also results in a large switching movement. This often results in space problems. In addition, a long switching movement also exacerbates reliable sealing of the switches and often necessitates a number of switch variants as a function of the size of the vehicle door gap. These problems in such a switch are avoided in that a switching lever (3) for operating the switching pin (5) on the switch housing (2) or switch flange (11) is supported such that it can pivot about a pivoting axis (12) arranged at right angles to the longitudinal axis of the switching pin (5), and offset laterally therefrom, and has a switching cam (4) resting on the head of the switching pin (5), the switching pin (5) being sealed on the operating side of the switch with respect to the switch housing (2) by means of a diaphragm seal (10) which is self-bracing both on the switch housing (2) and on the switching pin (5). <IMAGE>

Description

Die Erfindung betrifft einen wasser- und schmutzgeschützten Schalter, der insbesondere als Türkontaktschalter für Kraftfahrzeuge bestimmt ist, mit einem im Gehäuse des Schalters gegen den Druck einer Feder axial verschiebbaren Schaltstift mit Kontaktbrücke und mit am Schaltergehäuse angeordneten Kontakt-Anschlußteilen.The invention relates to a water and dirt-protected switch, which is intended in particular as a door contact switch for motor vehicles, with a switching pin axially displaceable against the pressure of a spring in the housing of the switch with a contact bridge and with contact connecting parts arranged on the switch housing.

Bei Türkontaktschaltern für Kraftfahrzeuge, die aber in der Regel auch für andere Anwendungen geeignet sind, entspricht im allgemeinen der Betätigungsweg direkt dem Schaltweg, das heißt ein großer Betätigungsweg resultiert auch in einem großen Schaltweg. Hierdurch kommt es häufig zu Platzproble­men. Außerdem erschwert ein langer Schaltweg auch die zuverlässige Abdichtung der Schalter und erfordert vielfach mehrere Schaltervarianten in Abhängigkeit vom Türspaltmaß am Fahrzeug.In door contact switches for motor vehicles, but which are generally also suitable for other applications, the actuation path generally corresponds directly to the switching path, that is to say a large actuation path also results in a large switching path. This often leads to space problems. In addition, a long switching distance also makes reliable sealing of the switches difficult and often requires several switch variants depending on the door gap dimension on the vehicle.

Aufgabe der Erfindung ist es daher, einen raumsparenden Schalter zu schaffen, der einfach und zuverlässig abgedich­tet ist und für unterschiedliche Türspaltmaße universell, das heißt ohne die Notwendigkeit von Varianten, eingesetzt werden kann.The object of the invention is therefore to provide a space-saving switch which is sealed simply and reliably and can be used universally for different door gap dimensions, that is to say without the need for variants.

Diese Aufgabe wird bei einem gattungsgemäßen Schalter gemäß der Erfindung dadurch gelöst, daß ein Schalthebel für die Betätigung des Schaltstiftes am Schaltergehäuse oder Schal­terflansch um eine zur Längsachse des Schaltstiftes quer und seitlich dazu versetzt angeordnete Schwenkachse drehbar gelagert ist und einen am Kopf des Schaltstiftes anliegen­den Schaltnocken aufweist, und daß der Schaltstift an der Betätigungsseite des Schalters gegenüber dem Schalterge­häuse durch eine Membrandichtung abgedichtet ist.This object is achieved in a generic switch according to the invention in that a switching lever for actuating the switching pin on the switch housing or switch flange is rotatably mounted about a pivot axis arranged transversely and laterally offset to the longitudinal axis of the switching pin and has a switching cam resting on the head of the switching pin , and that the switching pin on the actuating side of the switch is sealed from the switch housing by a membrane seal.

Die Erfindung hat den Vorteil, daß durch die Betätigung des Schaltstiftes durch einen schwenkbaren Schalthebel mit Schaltnocken ein relativ großer Betätigungsweg in einen wesentlich kleineren Schaltweg umgesetzt wird, wobei ein solcher Schalter unabhängig von der Größe des Türspalts funktionssicher ist. Gleichzeitig ist durch die Verwendung einer Membran eine zuverlässige Abdichtung zwischen Schalt­stift und Schaltergehäuse gewährleistet.The invention has the advantage that a relatively large actuation path is converted into a substantially smaller switching path by the actuation of the switching pin by a pivotable switching lever with switching cams, such a switch being functionally reliable regardless of the size of the door gap. At the same time, the use of a membrane ensures a reliable seal between the switching pin and the switch housing.

Eine besonders vorteilhafte Konstruktion eines solchen Schalters ergibt sich, wenn der Schalthebel als Abdeckkappe für den Schalterflansch ausgebildet und zwischen einer Of­fenstellung und einer Schließstellung anschlagbegrenzt ver­schwenkbar ist. Der Schalthebel ist nach einem weiteren vorteilhaften Merkmal der Erfindung dabei an einem mit dem Schaltergehäuse verbundenen Schalterflansch derart schwenk­bar gelagert, daß er in der Endlage der Funktion AUS völlig flach und bündig mit dem Schalterflansch liegt.A particularly advantageous construction of such a switch is obtained if the switch lever is designed as a cover cap for the switch flange and can be pivoted between an open position and a closed position in a stop-limited manner. According to a further advantageous feature of the invention, the shift lever is pivotably mounted on a switch flange connected to the switch housing in such a way that it lies completely flat and flush with the switch flange in the end position of the OFF function.

Der Schalterflansch und der Schalthebel weisen außerdem in­einandergreifende Rastteile auf, die zusammenwirkend eine aufhebbare Arretierung des Schalthebels in der AUS-Stellung bewirken.The switch flange and the shift lever also have interlocking latching parts which cooperatively bring about a lockable locking of the shift lever in the OFF position.

Da es außerdem vorteilhaft ist, wenn solche Schalter ab­schaltbar sind, z. B. wenn die Türen längere Zeit offenge­halten werden, kann der Schalthebel mit einer Rasteinrich­tung versehen sein, die den Schalter in der Funktion AUS arretiert. Hierfür ragt von dem Schalterflansch ein federn­des Rastteil auf, das in der Schließstellung in ein Rast­fenster mit einem Rastvorsprung am Schalthebel sperrend eingreift.Since it is also advantageous if such switches can be switched off, for. B. if the doors are kept open for a long time, the shift lever can be provided with a locking device that locks the switch in the OFF function. For this purpose, a resilient locking part protrudes from the switch flange, which engages in the locking position in a locking window with a locking projection on the shift lever.

Eine besonders einfache Anschlagbegrenzung für den Schalt­hebel ergibt sich ferner, wenn dieser in seiner Offenstel­lung mit einer zur Schwenkachse parallelen Anschlagfläche an der Oberseite des Schalterflansches sperrend anliegt.A particularly simple stop limitation for the switching lever also results if it is in its open position with a stop surface parallel to the pivot axis on the upper side of the switch flange.

Ferner ergibt sich eine besonders vorteilhafte und be­triebssichere Funktionsweise bei platzsparender kompakter Bauweise des Schalters, wenn der Schalthebel in seiner Offenstellung in einem Winkel von etwa 30 bis 50°, vor­zugsweise etwa 40°, gegenüber der Ebene des Schalterflan­sches geneigt ist, und wenn außerdem der Schaltnocken in einem spitzen Winkel von etwa 60 bis 40°, vorzugsweise etwa 50°, von dem Schalthebel schräg nach unten gegen die Schwenkachse gerichtet ist.Furthermore, there is a particularly advantageous and reliable operation with a space-saving, compact design of the switch if the switch lever in its open position is inclined at an angle of approximately 30 to 50 °, preferably approximately 40 °, with respect to the plane of the switch flange, and also if the switch cam at an acute angle of about 60 to 40 °, preferably about 50 °, is directed obliquely downward from the shift lever against the pivot axis.

A preferred embodiment of the invention is shown schematically in the drawing. Show it
  • Fig. 1 shows a vertical longitudinal section through a door contact switch for motor vehicles with an eccentrically mounted shift lever for the switch actuation and
  • FIG. 2 shows an interior view of such a door contact switch in a sectional plane II-II of FIG. 1.

Der Türkontaktschalter 1 wird am Türholm eines Kraftfahr­zeuges so montiert, daß der Türrahmen auf einen am Schal­tergehäuse 2 oder Schalterflansch 11 exzentrisch gelagerten Schalthebel 3 wirkt, der wiederum einen daran exzentrisch angeordneten Schaltnocken 4 trägt, der seinerseits über einen im Schaltergehäuse 2 axial verschiebbaren Schaltstift 5 die elektrische Funktion des Schalters auslöst. Der Schalthebel 3 ist als Abdeckkappe für das Schaltergehäuse 2 ausgebildet und zwischen einer Offen- und einer Schließ­stellung anschlagbegrenzt verschwenkbar. In seiner Offen­stellung von Fig. 1 liegt der Schalthebel 3 mit einer zur Schwenkachse 12 parallelen Anschlagfläche 3a an der Ober­seite des Schalterflansches 11 sperrend an.The door contact switch 1 is mounted on the door spar of a motor vehicle so that the door frame acts on an eccentrically mounted switch lever 3 on the switch housing 2 or switch flange 11, which in turn carries an eccentrically arranged switching cam 4, which in turn has an axially displaceable switching pin 5 in the switch housing 2 electrical function of the switch triggers. The switching lever 3 is designed as a cover cap for the switch housing 2 and can be pivoted between an open and a closed position in a stop-limited manner. In its open position of FIG. 1, the switching lever 3 is in a locking manner with a stop surface 3a parallel to the pivot axis 12 on the upper side of the switch flange 11.

Im Schaltergehäuse 2 sind mehrere kombinierte Kontakt-/An­schlußteile 6 mit angeprägten Kontaktfläche 7 angeordnet. Eine Kontaktbrücke 8 wird durch eine Druckfeder 9 in Anlage gegen den Schaltstift 5 gedrückt. Dieser wird umfaßt von einer Membrandichtung 10, die ihrerseits durch einen Schal­terflansch 11 dichtend gegen das Schaltergehäuse 2 gepreßt wird. Schaltergehäuse 2 und Schalterflansch 11 sind durch geeignete Maßnahmen, z. B. Klippung, verbunden. Der Schalt­hebel 3 mit seinem Schaltnocken 4 ist am oder im Schalter­flansch 11 um eine zur Betätigungsachse des Schaltstiftes 5 quer verlaufende Schwenkachse 12 drehbar gelagert. Bestand­teil des Schalterflansches 11 ist ferner ein federndes Rastteil 13, das bei vollständigem Herunterdrücken des Schalthebels 3 in ein Rastfenster. 14 mit einem Rastvor­sprung 14a am Schalthebel 3 eingreift und diesen arretiert. Ein Dichtring 15 an der Unterseite des Schalterflansches 11 dichtet den Schalter zur Karosserie hin ab. Der Schalter wird in der Karosserie durch einteilig mit dem Schalter­flansch 11 ausgebildete Halteklipse in herkömmlicher Aus­führung oder durch gesonderte Klemmfedern ebenfalls in bekannter Art und Weise befestigt; diese Befestigungsmittel sind in der Zeichnung daher nicht dargestellt.In the switch housing 2, a plurality of combined contact / connection parts 6 with an impressed contact surface 7 are arranged. A contact bridge 8 is pressed against the switching pin 5 by a compression spring 9. This is encompassed by a membrane seal 10, which in turn is sealingly pressed against the switch housing 2 by a switch flange 11. Switch housing 2 and switch flange 11 are by suitable measures, for. B. clipping connected. The switching lever 3 with its switching cam 4 is rotatably mounted on or in the switch flange 11 about a pivot axis 12 which runs transversely to the actuating axis of the switching pin 5. Part of the switch flange 11 is also a resilient latching part 13 which, when the switching lever 3 is completely pressed down into a latching window. 14 engages with a locking projection 14a on the shift lever 3 and locks it. A sealing ring 15 on the underside of the switch flange 11 seals the switch towards the body. The desk is also fixed in a known manner in the body by means of retaining clips formed in one piece with the switch flange 11 in a conventional design or by separate clamping springs; these fasteners are therefore not shown in the drawing.

Der Schalterflansch 11 und der Schalthebel 3 sind außerdem mit Anschlägen so ausgebildet, daß der schwenkbar im oder am Schalterflansch 11 gelagerte Schalthebel 3 über einen vorbestimmten Öffnungswinkel hinaus nicht bewegt werden kann.The switch flange 11 and the shift lever 3 are also formed with stops so that the shift lever 3 pivotally mounted in or on the switch flange 11 cannot be moved beyond a predetermined opening angle.

Der in eine entsprechende Karosserieöffnung eingebaute Schalter befindet sich bei geöffneter Fahrzeugtür in der EIN-Schaltstellung von Fig. 1. Der Stromkreis ist geschlos­sen. Wird die Fahrzeugtür geschlossen, so bewegt sich der Schalthebel 3 aus seiner in einem Winkel von etwa 30 bis 50°, vorzugsweise etwa 40°, geneigten Offenstellung von Fig. 1 in Richtung auf den Schalterflansch 11, und der mit einer Schaltkurve 4a ausgebildete, in einem spitzen Winkel von etwa 60 bis 40°, vorzugsweise etwa 50°, von dem Schalt­hebel 3 schräg nach unten gegen die Schwenkachse 12 des Schalthebels 3 gerichtete Schaltnocken 4 wirkt auf eine Abriebschutzfläche 16 am Kopf des Schaltstiftes 5 ein, so daß dieser sich zum Schalterinneren hin bewegt, wodurch die Kontaktbrücke 8 durch zum Schaltergehäuse 2 gehörende seitliche Rampen 17 von den Kontaktflächen 7 der kombinier­ten Kontakt-/Anschlußteile 6 abgehoben und der Stromkreis unterbrochen wird. Schalterflansch 11 und Schalthebel 3 sind maßlich so ausgelegt, daß der bei völlig geschlossener Tür verbleibende Türspalt den Schalthebel 3 nur so weit zum Schalterflansch 11 hin hält, daß die aus dem Rastteil 13 und dem Rastfenster 14 mit Rastvorsprung 14a bestehende Arretierung noch nicht zur Wirkung kommt. Soll der Schalter arretiert werden, so wird der Schalthebel 3 von Hand bis zum Einrasten in die in Fig. 1 gestrichelt gezeigte Stel­lung hinuntergedrückt, in der das hakenförmige Rastteil 13 den Rastvorsprung 14a an dem Rastfenster 14 hintergreift. Die Arretierung kann durch Zurückbiegen des Rastteiles 13 leicht wieder aufgehoben werden.The switch installed in a corresponding body opening is in the ON switch position of FIG. 1 when the vehicle door is open. The circuit is closed. If the vehicle door is closed, the shift lever 3 moves from its open position inclined at an angle of approximately 30 to 50 °, preferably approximately 40 °, in FIG. 1 in the direction of the switch flange 11, and that formed with a switching curve 4a in an acute angle of about 60 to 40 °, preferably about 50 °, from the shift lever 3 obliquely downward against the pivot axis 12 of the shift lever 3 switching cams 4 acts on an abrasion protection surface 16 on the head of the switching pin 5 so that it is towards the inside of the switch Moved, whereby the contact bridge 8 is lifted by the side ramps 17 belonging to the switch housing 2 from the contact surfaces 7 of the combined contact / connection parts 6 and the circuit is interrupted. Switch flange 11 and switching lever 3 are dimensionally designed so that the door gap remaining when the door is completely closed holds the switching lever 3 only so far towards the switch flange 11 that the locking part 13 and the locking window 14 with locking projection 14a does not yet come into effect . Should the switch are locked, the shift lever 3 is pressed by hand until it engages into the position shown in dashed lines in FIG. 1, in which the hook-shaped latching part 13 engages behind the latching projection 14a on the latching window 14. The locking can be easily canceled by bending back the locking part 13.

Der Schalter kann mit zwei, drei oder mehr kombinierten Kontakt-/Anschlußteilen 6 versehen sein. Bei z. B. drei kombinierten Kontakt-/Anschlußteilen 6 kann zwecks besseren Schaltablaufes eine symmetrische Belastung der Kontakt­brücke 8 durch einen zusätzlichen Vorsprung 18 am Schalter­gehäuse 2 bewirkt werden.The switch can be provided with two, three or more combined contact / connection parts 6. At z. B. three combined contact / connecting parts 6 can be effected for an improved switching sequence, a symmetrical loading of the contact bridge 8 by an additional projection 18 on the switch housing 2.

Die Kontakt/Anschlußteile 6 können im Schaltergehäuse 2 auf unterschiedliche herkömmliche Art befestigt sein, zweckmäs­sigerweise aber so, daß keine Undichtigkeit zum Schalterin­neren besteht. Ein ringförmiger Fortsatz 19 des Schalterge­häuses 2 kann dem Steckerteil eines Anschlußkabels entspre­chend ebenfalls abdichtend ausgebildet sein.The contact / connecting parts 6 can be fastened in the switch housing 2 in different conventional ways, but expediently so that there is no leakage to the inside of the switch. An annular extension 19 of the switch housing 2 can also be designed to be sealing in accordance with the plug part of a connecting cable.
