Description

Die gegenständliche Erfindung betrifft eine Vorrichtung zur Unterbrechung des Stromflusses in einem Kabel, das von der in einem Kraftfahrzeug angeordneten Batterie zu einem gleichfalls im Kraftfahrzeug angeordneten Verbraucher, wie dem Starter, dem Motor u.dgl., führt.The subject invention relates to a device for interruption of current flow in a cable from that in a motor vehicle arranged battery to a likewise in the motor vehicle arranged consumers, such as the starter, the engine and the like.

Es besteht die Forderung, in einem Kraftfahrzeug eine Vorrichtung vorzusehen, durch welche bei einem Unfall der Stromfluß zwischen der Batterie und den an die Batterie angeschlossenen Verbrauchern, insbesondere dem Startgerät, unterbrochen wird. Der Grund hierfür liegt darin, daß durch unfallbedingte Beschädigungen der stromführenden Kabel Kurzschlüsse bedingt werden können, durch welche Brände und Explosionen verursacht werden können.There is a requirement to provide a device in a motor vehicle, through which in an accident the current flow between the Battery and the consumers connected to the battery, in particular the starting device. The reason for this is in that due to accidental damage to the current Cable short circuits can be caused by which fires and Explosions can be caused.

Aus dem DE GM 84 33 042.2 ist eine Vorrichtung bekannt, welche aus einem mit einer zylindrischen Ausnehmung ausgebildeten Gehäuse mit einer ersten Anschlußklemme und einem zylindrischen Bolzen mit einer zweiten Anschlußklemme besteht, wobei der Bolzen in die Ausnehmung einsetzbar und in dieser durch Reibungsschluß gehalten ist. An die beiden Anschlußklemmen sind das von der Batterie herführende Kabel und das zu den Verbrauchern wegführende Kabel angeschlossen. Weiters befindet sich im Gehäuse ein Treibsatz in Form eines pyrotechnischen Elementes, welches durch einen Sensor auslösbar ist.A device is known from DE GM 84 33 042.2, which consists of a housing formed with a cylindrical recess a first connector and a cylindrical bolt with a second connector exists, the bolt in the recess can be used and is held in this by friction. To the two Terminals are the cable leading from the battery and the cable leading to the consumer is connected. Furthermore located a propellant in the form of a pyrotechnic Element that can be triggered by a sensor.

Im Falle eines Unfalles wird vom Sensor an den Treibsatz ein Impuls abgegeben, wodurch dieser gezündet wird. Durch den hierdurch erzeugten Gasdruck wird der in der zylindrischen Ausnehmung befindliche Bolzen aus dieser hinaus gefördert, wodurch die zwischen der Batterie und den Verbrauchern bestehende elektrische Verbindung unterbrochen wird.In the event of an accident, the sensor sends an impulse to the propellant delivered, which is ignited. By the generated thereby Gas pressure becomes the one in the cylindrical recess Bolts are conveyed out of this, creating the between the battery and the existing electrical connection to the consumers is interrupted becomes.

Dieser bekannten Vorrichtung haftet jedoch der Nachteil an, daß durch die reibungsschlüssige Verbindung der beiden Kupplungsteile sowohl eine mechanische Verbindung als auch eine elektrische Verbindung bewirkt wird. Um dabei sowohl eine gute mechanische Verbindung als auch eine gute elektrische Verbindung zu gewährleisten, müssen die einander zugeordneten Kupplungsteile exakt übereinstimmen, wodurch hohe Herstellungskosten bedingt werden. Weiters besteht die Gefahr, daß die beiden Kupplungsteile aufgrund der beim Betrieb des Kraftfahrzeuges auftretenden Vibrationen voneinander gelöst werden, wodurch entweder der Übergangswiderstand erhöht wird oder die elektrische Verbindung vollständig unterbrochen wird. Weiters kann durch einen erhöhten Stromfluß ein Verschweißen der beiden Kupplungsteile erfolgen, wodurch die Funktionsfähigkeit der Vorrichtung nicht mehr gewährleistet ist. Zudem kann auch infolge von durch mechanische Einflüsse verursachten Verformungen, z.B. durch einen Wärmeverzug, der Reibungsschluß zwischen den beiden Kupplungsteilen so groß werden, daß die Funktionsfähigkeit dieser Vorrichtung nicht mehr gewährleistet ist.However, this known device has the disadvantage that the frictional connection of the two coupling parts both causes a mechanical connection as well as an electrical connection becomes. To ensure both a good mechanical connection to ensure a good electrical connection mutually assigned coupling parts match exactly, whereby high manufacturing costs are caused. There is also the risk that the two coupling parts due to the operation of the motor vehicle occurring vibrations are solved from each other, whereby either the contact resistance is increased or the electrical Connection is completely interrupted. Furthermore, by one the two coupling parts are welded together, whereby the functionality of the device is no longer guaranteed is. In addition, due to mechanical influences deformations caused, e.g. due to a heat delay that Friction between the two coupling parts become so large that the functionality of this device is no longer guaranteed is.

Wie dies aus den Fig. 1 und 1a ersichtlich ist, besteht eine derartige Vorrichtung aus zwei voneinander im Abstand befindlichen zylindrischen Hülsen 1 und 2, welche aus elektrisch leitendem Material, z.B. einem Metall, wie Messing oder Bronze, hergestellt sind und welche durch eine Ummantelung 3, welche aus elektrisch nicht leitendem Material, z.B. einem Kunststoff, gefertigt ist, umschlossen sind. Durch die Ummantelung 3 sind die beiden Hülsen 1 und 2 miteinander mechanisch verbunden. Da sich jedoch die beiden Hülsen 1 und 2 voneinander im Abstand befinden, sind sie voneinander elektrisch isoliert.As can be seen from FIGS. 1 and 1a, there is such a device from two cylindrical ones spaced from each other Sleeves 1 and 2, which are made of electrically conductive material, e.g. one Metal, such as brass or bronze, are made and which by a Jacket 3, which is made of electrically non-conductive material, e.g. a plastic that is manufactured, are enclosed. Through the casing 3, the two sleeves 1 and 2 are mechanically connected to one another. However, since the two sleeves 1 and 2 are at a distance from each other are electrically isolated from each other.

Von der ersten Hülse 1 ragen zwei Klemmen 11 und 12 ab, welche zum Anschluß von Kabeln 13 und 14 dienen. Von der zweiten Hülse 2 ragen zwei Klemmen 21 und 22 ab, welche zum Anscbluß von Kabeln 23 und 24 dienen.From the first sleeve 1 protrude two terminals 11 and 12, which for Connection of cables 13 and 14 are used. Protrude from the second sleeve 2 two terminals 21 and 22 from which to connect cables 23 and 24 serve.

Die Hülse 1 ist an ihrem freien Ende mit einem Innengewinde 15 ausgebildet, in welches eine Abschlußkappe 16 eingeschraubt ist, durch welche der Innenraum der Hülse 1 verschlossen ist. Innerhalb der Kappe 16 befindet sich ein pyrotechnisches Element 4, an dessen Zünder 41 ein Kabel 42 angeschlossen ist, welches von einem Sensor herführt.The sleeve 1 is formed at its free end with an internal thread 15, into which an end cap 16 is screwed, through which the interior of the sleeve 1 is closed. Inside the cap 16 there is a pyrotechnic element 4, at the igniter 41 Cable 42 is connected, which leads from a sensor.

Die zweite Hülse 2 ist an ihrem freien Ende mit einer Stirnwand 26 ausgebildet. In der Stirnwand 26 befindet sich eine Bohrung 29, in welche ein Stopfen 27 eingesetzt ist. In dem von den beiden Hülsen 1 und 2 umschlossenen Hohlraum 10 befindet sich ein zylindrisches Schaltelement 5, welches an seiner Außenfläche mit Kontaktfedern 51 ausgebildet ist, welche an die Innenflächen 18 und 28 der beiden Hülsen 1 und 2 anliegen. Weiters befindet sich zwischen dem pyrotechnischen Element 4 und dem Schaltelement 5 eine Druckplatte 6.The second sleeve 2 has an end wall 26 at its free end educated. In the end wall 26 there is a bore 29 in which a plug 27 is inserted. In the case of the two sleeves 1 and 2 enclosed cavity 10 is a cylindrical switching element 5, which is formed on its outer surface with contact springs 51 which is on the inner surfaces 18 and 28 of the two sleeves 1st and 2 concern. It is also located between the pyrotechnic Element 4 and the switching element 5 a pressure plate 6.

Das Kabel 13 ist an die Batterie angeschlossen. Das Kabel 23 führt zum Startgerät. Das Kabel 14 führt zu einer Notstromversorgung und das Kabel 24 führt zum Bordnetz des Kraftfahrzeuges.The cable 13 is connected to the battery. The cable 23 leads to Starter device. The cable 14 leads to an emergency power supply and that Cable 24 leads to the vehicle electrical system.

In der in den Fig. 1 und 1a gezeigten Stellung des Schaltelementes 5 liegen dessen Kontaktfedern 51 an die Innenflächen 18 und 28 der beiden Hülsen 1 und 2 an, wodurch die Klemmen 11, 12, 21 und 22 miteinander elektrisch verbunden sind. Hierdurch sind sämtliche Geräte des Kraftfahrzeuges an die Batterie angeschlossen. Soferne infolge eines Unfalles der Stromfluß von der Batterie unterbrochen werden muß, wird vom Sensor über die Leitung 42 an den Zünder 41 des pyrotechnischen Elementes 4 ein Impuls abgegeben, wodurch das pyrotechnische Element 4 gezündet wird. Durch den hierdurch bewirkten Gasdruck wird über die Druckplatte 6 das Schaltelement 5 aus der in den Fig. 1 und 1a gezeigten Stellung nach rechts verschoben. Hierdurch tritt im rechten Teil des Hohlraumes 10 ein Druckanstieg ein, wodurch der Stopfen 27 aus der Bohrung 29 hinausgedrückt wird. Hierdurch kann das Schaltelement 5 in die strichliert gezeigte Stellung verschoben werden. Da sich somit das Schaltelement 5 nur innerhalb der zweiten Hülse 2 befindet, wird der Stromfluß zu den Kabeln 23 und 24 unterbrochen. Demgegenüber bleibt der Stromfluß zum Kabel 14 aufrecht, wodurch eine Notstromversorgung gewährleistet ist.In the position of the switching element 5 shown in FIGS. 1 and 1a are the contact springs 51 on the inner surfaces 18 and 28 of the two Sleeves 1 and 2 on, which clamps 11, 12, 21 and 22 together are electrically connected. This means all devices of the motor vehicle connected to the battery. Soferne as a result of a Accident the current flow from the battery must be interrupted from the sensor via line 42 to the igniter 41 of the pyrotechnic Element 4 given a pulse, causing the pyrotechnic element 4 is ignited. Due to the gas pressure caused thereby Via the pressure plate 6, the switching element 5 from that in FIGS. 1 and 1a shown position shifted to the right. This occurs in the right Part of the cavity 10 a pressure increase, whereby the plug 27th is pressed out of the bore 29. This allows the switching element 5 can be moved to the position shown in dashed lines. That I thus the switching element 5 is only inside the second sleeve 2, the current flow to the cables 23 and 24 is interrupted. In contrast, the current flow to the cable 14 remains, whereby an emergency power supply is guaranteed.

Beim Ausführungsbeispiel gemäß den Fig. 2 und 2a ist als Stellelement für das Schaltelement 5 eine Druckfeder 7 vorgesehen, welche durch einen Schmelzdraht 7a in der gespannten Lage gehalten ist. Sobald der Sensor anspricht, gelangt in den Schmelzdraht 7a ein Stromstoß, wodurch dieser geschmolzen wird, sodaß er die Druckleder 7 freigibt, wodurch das Schaltelement 5 in seine rechte Lage verschoben wird. Hierdurch wird der Stromfluß von der ersten Hülse 1 in die zweite Hülse 2 unterbrochen.
Beim Ausführungsbeispiel gemäß den Fig. 3 und 3a ist ein Hohlraum 8 vorgesehen, welcher über eine Leitung 81 an einen außerhalb der Vorrichtung befindlichen Druckspeicher angeschlossen ist. Sobald der Sensor anspricht, wird der Hohlraum 8 vom Druckspeicher her mit einem Druckmedium, z.B. mit Druckluft, beaufschlagt, wodurch das Schaltelement 5 in seine nicht leitende Stellung verschoben wird.
In the exemplary embodiment according to FIGS. 2 and 2a, a compression spring 7 is provided as an actuating element for the switching element 5 and is held in the tensioned position by a fuse wire 7a. As soon as the sensor responds, a current surge enters the fusible wire 7a, causing it to melt, so that it releases the printing leather 7, as a result of which the switching element 5 is shifted into its right-hand position. As a result, the current flow from the first sleeve 1 into the second sleeve 2 is interrupted.
In the exemplary embodiment according to FIGS. 3 and 3a, a cavity 8 is provided, which is connected via a line 81 to a pressure accumulator located outside the device. As soon as the sensor responds, a pressure medium, for example compressed air, is applied to the cavity 8 from the pressure accumulator, as a result of which the switching element 5 is displaced into its non-conductive position.

Um nach einer Verschiebung des Schaltelementes 5 und trotz der hierdurch bewirkten Unterbrechung des Stromflusses von der Batterie her einen Notbetrieb zu ermöglichen, kann das Schaltelement 5 mittels eines Werkzeuges, welches durch die Bohrung 29 hindurchgeführt wird, in seine ursprüngliche Stellung zurückverschoben werden, wodurch die elektrische Verbindung wieder hergestellt wird. Um die Vorrichtung wieder vollständig funktionsfähig zu machen, wird die Abschlußkappe 16 entfernt und wird in die erste Hülse 1 ein neues Stellelement in Form eines pyrotechnischen Elementes 4 oder einer Druckfeder 7 eingesetzt.In order after a shift of the switching element 5 and despite this caused interruption of the current flow from the battery To enable emergency operation, the switching element 5 by means of a tool which is passed through the bore 29, to be moved back to its original position, causing the electrical connection is restored. To the device To make it fully functional again, the end cap 16 removed and in the first sleeve 1, a new control element in the form a pyrotechnic element 4 or a compression spring 7 is used.

Das Ausführungsbeispiel gemäß den Fig. 4 und 4a unterscheidet sich vom Ausführungsbeispiel gemäß den Fig. 1 und 1a dadurch, daß die beiden Hülsen 1a und 2a an den einander zugewandten Enden mit jeweils einem Außengewinde 10a und 20a ausgebildet sind und daß die Ummantelung 3a, welche gleichfalls als zylindrische Hülse ausgebildet ist und durch welche die beiden Hülsen 1a und 2a voneinander elektrisch isoliert sind, mit zwei Innengewinden 30a ausgebildet ist, in welche die Hülsen 1a und 2a eingeschraubt sind. Weiters ist das pyrotechnische Element 4a in die Hülse 1a von deren freiem Ende her eingesetzt, wobei es an einer Abschlußwand 41 der Hülse 1a von innen zur Anlage kommt. Dabei durchsetzt eine Abschlußkappe 16a eine in der Abschlußwand 41 vorgesehene Bohrung 15a. Durch die Abschlußkappe 16a ist die zum pyrotechnischen Element 4a führende Leitung 42 hindurchgeführt.The embodiment according to FIGS. 4 and 4a differs from the embodiment of FIGS. 1 and 1a in that the with both sleeves 1a and 2a at the ends facing each other an external thread 10a and 20a are formed and that the Sheath 3a, which is also designed as a cylindrical sleeve is and through which the two sleeves 1a and 2a of each other electrically are isolated, is formed with two internal threads 30a, in which the sleeves 1a and 2a are screwed in. Another is pyrotechnic Element 4a inserted into the sleeve 1a from its free end, it on an end wall 41 of the sleeve 1a from the inside to the system is coming. A cap 16a penetrates one in the end wall 41 provided bore 15a. Through the end cap 16a, the line 42 leading to the pyrotechnic element 4a is passed through.

Weiters ragen von den freien Enden der Hülsen 1a und 2a nur zwei Klemmen 11a und 21a ab, an welche einerseits die Leitungen 13 und 14 und andererseits die Leitungen 23 und 24 angeschlossen sind. Zudem ist das im Innenraum 10 der beiden Hülsen 1a und 2a angeordnete Schaltelement als einseitig geschlossene Hülse 5a ausgebildet, deren dem pyrotechnischen Element 4a zugewandte Stirnfläche die Druckplatte bildet, an welcher das pyrotechnische Element 4a zur Wirkung kommt. Schließlich ist das Schaltelement 5a an seinen beiden Enden mit radial nach außen abragenden ringförmigen Flanschen 52 ausgebildet, welche einen hohlzylindrischen Raum begrenzen, in welchem die Kontaktfedern 51 angeordnet sind.Furthermore, only two protrude from the free ends of the sleeves 1a and 2a Terminals 11a and 21a, to which lines 13 and 14 and on the other hand the lines 23 and 24 are connected. In addition is that arranged in the interior 10 of the two sleeves 1a and 2a Switching element designed as a sleeve 5a closed on one side, the the pyrotechnic element 4a facing the pressure plate forms on which the pyrotechnic element 4a to effect is coming. Finally, the switching element 5a is at both ends formed with radially outwardly projecting annular flanges 52, which delimit a hollow cylindrical space in which the Contact springs 51 are arranged.

Die Wirkungsweise der Vorrichtung gemäß den Fig. 4 und 4a ist die gleiche wie diejenige der Vorrichtung gemäß den Fig. 1 und 1a.The operation of the device according to FIGS. 4 and 4a is same as that of the device according to FIGS. 1 and 1a.
