Abstract

A circuit breaker for motor vehicles, particularly for arrangement between the battery and earth, has a switch which can be moved into an interruption position. In order to permit automatic circuit interruption in the event of an accident, the switch is constructed as a switch arm (8) which is arranged like a pendulum about a rotation axis (4, 6). This switch arm (8) can be pivoted out of a circuit-closing position into a circuit-interrupting position, by means of acceleration forces caused by a collision of the motor vehicle. <IMAGE>

Gleiche Bauteile in den Figuren der Zeichnung sind mit den gleichen Bezugszeichen versehen.The same components in the figures of the drawing are provided with the same reference numerals.

Die Zeichnung zeigt einen Stromkreisunterbrecher 2 mit einem pendelartig um eine Metall-Lagerbuchse 6 angeordneten Schalterarm 8 aus Metall mit Gewicht 10. Die Lagerbuchse 6 ist zwischen zwei beabstandeten kreissegmentförmigen Platten mit Hilfe eines Schraubbolzens 4 eingespannt. Eine Platte bildet ein Oberteil 12 aus einem Isoliermaterial, beispielsweise Bakelitharz, und die andere Platte ein Unterteil 14 aus Metall, beispielsweise Messing.The drawing shows a circuit breaker 2 with a pendulum-like around a metal bearing bush 6 arranged switch arm 8 made of metal with weight 10. The bearing bush 6 is clamped between two spaced circular segment-shaped plates with the aid of a screw bolt 4. One plate forms an upper part 12 made of an insulating material, for example bakelite resin, and the other plate forms a lower part 14 made of metal, for example brass.

Unterteilseitig haltert der Schraubbolzen 4 einen Haltewinkel 16, an dem eine Befestigungslasche 18 mittels Schraubverbindung 20 angeschraubt ist. Mit Hilfe der Befestigungslasche 18 ist der Stromkreisunterbrecher 2 an eine Motorraumwand montierbar.The lower part of the screw bolt 4 holds a bracket 16 to which a fastening tab 18 is screwed by means of a screw connection 20. With the aid of the fastening tab 18, the circuit breaker 2 can be mounted on an engine compartment wall.

Unterteilseitig haltert der Schraubbolzen 4 zwischen Haltewinkel 16 und Unterteil 14 ein Blech 22, in dem ein Druckknopfschalter 24 befestigt ist, dessen federnd gelagerter Druckstift 26 in einer Bohrung 28 des Unterteiles 14 geführt ist und in eine rückseitige Vertiefung 30 des Schalterarmes 8 in der Schaltkreisschließstellung des Schaltkreisunterbrechers 2 einrastet.On the lower part, the screw bolt 4 holds a bracket 22 between the mounting bracket 16 and the lower part 14, in which a push-button switch 24 is fastened, the spring-mounted push pin 26 of which is guided in a bore 28 of the lower part 14 and into a rear recess 30 of the switch arm 8 in the circuit-closed position of the Circuit breaker 2 engages.

Beidseitig der Stromkreisschließstellung des Schalterarmes sind zwischen Ober- und Unterteil mittels Senkschrauben 32, 34 Buchsen 36, 38 eingespannt, welche jeweils eine Blattfeder 40, 42 mit Auswinklung 44, 46 haltern.On both sides of the circuit closed position of the switch arm, bushings 36, 38 are clamped between the upper and lower part by means of countersunk screws 32, 34, each of which holds a leaf spring 40, 42 with an angle 44, 46.

Das Oberteil 12 weist ein rechteckförmiges Loch 48 auf, in dem ein auf dem Schalterarm unter Druck aufliegender Kontaktkörper 50 aus Metall geführt ist, welcher einen Gewindeschaft 52 aufweist, der durch eine Bohrung 54 einer den Druckkörper beaufschlagenden Führungsplatte 56 hindurchragt und auf dem eine Mutter 58 zum Festschrauben des Kontaktkörpers an der Führungsplatte aufgeschraubt ist.The upper part 12 has a rectangular hole 48 in which a metal contact body 50, which rests under pressure on the switch arm, is guided, which has a threaded shaft 52 which projects through a bore 54 of a guide plate 56 which acts on the pressure body and on which a nut 58 for screwing the contact body onto the guide plate.

Beidseitig des Kontaktkörpers 50 ist die Führungsplatte 56 mit Hilfe von Senkschrauben 58, 60, die in das Oberteil von innen eingeschraubt sind und durch Bohrungen der Führungsplatte hindurchgehen, gehalten, wobei die Führungsplatte 56 auf die Senkschrauben umgebenden Buchsen 62, 64 verschiebbar gelagert ist. Auf die nach außen ragenden Gewindeschäfte der Senkschrauben 58, 60 sind Rändelmuttern 66, 68 aufgeschraubt. Zwischen den Rändelmuttern und der Führungsplatte 56 stützen sich Schraubendruckfedern 70, 72 ab. Durch Verdrehen der Rändelmuttern kann über die Änderung der Federkraft die Belastung des Kontaktkörpers und damit dessen Anlagedruck auf dem Schalterarm 8 und darüber wiederum die Haltekraft des Druckstiftes 26 erhöht werden.The guide plate 56 is held on both sides of the contact body 50 by means of countersunk screws 58, 60 which are screwed into the upper part from the inside and pass through bores in the guide plate, the guide plate 56 being slidably mounted on the bushings 62, 64 surrounding the countersunk screws. Knurled nuts 66, 68 are screwed onto the outwardly projecting threaded shafts of the countersunk screws 58, 60. Helical compression springs 70, 72 are supported between the knurled nuts and the guide plate 56. By turning the knurled nuts, the load on the contact body and thus its contact pressure on the switch arm 8 and, in turn, the holding force of the pressure pin 26 can be increased by changing the spring force.

Der Schalterarm 8 weist außenseitig eine Längsausnehmung 74 auf, in die beim Verschwenken des Schalterarmes eine der Blattfedern 40 oder 42 mit den Auswinklungen 44, 46 einrasten.The switch arm 8 has a longitudinal recess 74 on the outside, into which one of the leaf springs 40 or 42 with the bends 44, 46 engage when the switch arm is pivoted.

Im Schalterarm 8 kann ferner eine Bohrung 76 vorgesehen sein zum Anbringen eines aus dem Fahrzeuginnern heraus betätigbaren Zugseiles 78, wodurch der Stromkreisunterbrecher 2 manuell betätigbar ist.A bore 76 can also be provided in the switch arm 8 for attaching a pull cable 78 which can be actuated from inside the vehicle, as a result of which the circuit breaker 2 can be actuated manually.

Auf dem Gewindeschaft 52 des Kontaktkörpers 50 ist die Öse 80 des Massekabels 82 der Autobatterie aufgeschraubt. Auf diese Weise ist der Stromkreisunterbrecher zwischen Minuspol der Batterie und Masse geschaltet.On the threaded shaft 52 of the contact body 50 the eyelet 80 of the earth cable 82 of the car battery is screwed on. In this way, the circuit breaker is connected between the negative pole of the battery and ground.

Bei einer durch eine Kollision auftretenden Beschleunigungskraft, gleich welcher Richtung, wird der pendelartige Schalterarm 8 aus seiner mittigen Stromkreisschließstellung 84 nach links oder rechts in eine der beiden Stromkreisunterbrechungsstellungen 86, 88 verschwenkt, in denen der Stromkreis unterbrochen ist, da in diesen beiden Stellungen der Kontaktkörper 50 nicht mehr in Kontakt mit dem Schalterarm 8 steht.In the event of an acceleration force occurring due to a collision, regardless of the direction, the pendulum-like switch arm 8 is pivoted from its central circuit closing position 84 to the left or right into one of the two circuit interruption positions 86, 88, in which the circuit is interrupted, since in these two positions the contact body 50 is no longer in contact with the switch arm 8.

Das Verschwenken in die Stromunterbrechungsposition kann auch durch Betätigung des Zugseiles 78 erfolgen.The pivoting into the power cut position can also be done by operating the pull cable 78.

Die Rückstellung erfolgt dann manuell, wobei die ordnungsgemäße Betriebsstellung, d. h. der geschlossene Stromkreis, durch eine am Stromkreisunterbrecher 2 angeordnete Leuchtdiode (nicht dargestellt) angezeigt werden kann.The reset is then carried out manually, the correct operating position, i.e. H. the closed circuit can be indicated by a light-emitting diode (not shown) arranged on the circuit breaker 2.

Der Stromkreisunterbrecher 2 wird vorzugsweise in einer Schräglage von 45° im Motorraum an der Motorraumwandung angebracht. Eine senkrechte Anordnung oder jede beliebige winklige Anordnung ist ebenfalls möglich.The circuit breaker 2 is preferably attached to the engine compartment wall in an inclined position of 45 ° in the engine compartment. A vertical arrangement or any angular arrangement is also possible.
