Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur einmaligen und dauerhaften Trennung einer elektrischen Verbindung, insbesondere in einem Kraftfahrzeug, nach dem Oberbegriff des Anspruchs 1.The The invention relates to a method and a device for a one-off and permanent separation of an electrical connection, in particular in a motor vehicle, according to the preamble of claim 1.
Insbesondere
in der KFZ-Technik ist es wünschenswert,
elektrische Starkstromkreise von der Autobatterie nach einem Unfall
zu trennen, um Zündquellen
in Form von Funken zu vermeiden. Durch Funken können auslaufendes Benzin oder
Benzin-Luft-Gemische gezündet
werden und das Unfallfahrzeug in Brand setzen. Neben Anordnungen,
bei denen eine Trennung eines elektrischen Leiters mittels mechanischer
Mittel erfolgt, ist aus der
Das nach der Zündung entstehende Gas drückt einen vorbestimmten Abschnitt aus dem Leiter heraus. Dieser Abschnitt wird in einem Behälter so aufgefangen, dass er in einer Entfernung vom Leiter verbleibt, wodurch eine erneute Verbindung der Leiterenden verhindert wird.The after the ignition emerging gas presses a predetermined section out of the ladder. this section is in a container so caught up that he stays at a distance from the ladder, whereby a reconnection of the conductor ends is prevented.
Diese Anordnung weist den Nachteil auf, dass ein thermisch empfindlicher Stoff verwendet wird, der das Treibladungspulver zündet. Dieser thermisch empfindliche Stoff stellt einen zusätzlichen Aufwand dar. Weiterhin besteht der Nachteil, dass ein Abschnitt der Leitung ausgedrückt wird und dadurch der zusätzliche Behälter für die Aufnahme des ausgedrückten Leitungsabschnitts vorhanden sein muss, um eine erneute Verbindung der durchtrennten Leitungsenden zu verhindern.These Arrangement has the disadvantage that a thermally sensitive Substance is used which ignites the propellant charge powder. This thermally sensitive material is an additional expense. Furthermore There is the disadvantage that a section of the line is expressed and thereby the additional container for the Recording of the expressed Line section must be present to reconnect to prevent the severed line ends.
Der Erfindung liegt die Aufgabe zugrunde, die einmalige und dauerhafte Trennung eines Leiters, insbesondere in einem Kraftfahrzeug, zu vereinfachen.Of the Invention is based on the object, the unique and permanent Separation of a conductor, especially in a motor vehicle, too simplify.
Erfindungsgemäß wird das gemäß den Merkmalen des Anspruchs 1 erreicht.According to the invention according to the characteristics of claim 1 achieved.
Bei einem Verfahren zur einmaligen und dauerhaften Trennung einer elektrischen Verbindung, insbesondere in einem Kraftfahrzeug, mittels einer Druckwelle, ist erfindungsgemäß vorgesehen, dass eine elektrische Leitung an einer Sollbruchstelle getrennt und zusätzlich im Bereich der Sollbruchstelle verformt wird, wobei die durchtrennten Enden der Leitung Bestandteil der jeweiligen Leitungsseite bleiben. Diese Verfahrensweise weist den Vorteil auf, dass kein loser Trennungsabschnitt erzeugt wird, der gesondert aufbewahrt werden muss, um eine erneute Verbindung der Leitungsenden mit Sicherheit zu vermeiden. Die erneute Verbindung der Leitungsenden wird durch die zusätzliche Verformung verhindert, wodurch die Leitungsenden ausreichend weit voneinander entfernt werden. Dabei erfolgt die Verformung sowohl vor der Trennung als auch noch nach der Trennung durch die Druckwelle. Die Verformung und Trennung erfolgt in einem Kraftfahrzeug durch den beim Zünden eines Airbaganzünders entstehenden Gasdruck. Dadurch ist kein thermisch empfindlicher Stoff erforderlich.at a method for the unique and permanent separation of an electrical Connection, in particular in a motor vehicle, by means of a pressure wave, is provided according to the invention, that an electrical line is disconnected at a predetermined breaking point and additionally deformed in the region of the predetermined breaking point, wherein the severed Ends of the line remain part of the respective line side. This procedure has the advantage that no loose separation section which needs to be stored separately to make another To avoid connection of the cable ends with certainty. The renewed Connection of the cable ends is prevented by the additional deformation, whereby the line ends sufficiently far apart become. The deformation takes place both before the separation as even after the separation by the pressure wave. The deformation and separation takes place in a motor vehicle by the ignition of a Airbaganzünders resulting gas pressure. This is not a thermally sensitive Fabric required.
Bei einer Vorrichtung zur einmaligen und dauerhaften Trennung einer elektrischen Verbindung mittels einer Druckwelle, die insbesondere zur Durchführung des vorgenannten Verfahrens geeignet ist, weist erfindungsgemäß ein Abschnitt eines elektrischen Leiters, der durchtrennt werden soll, sowohl eine Sollbruchstelle als auch mindestens eine Biegestelle auf. Dabei können die Sollbruchstelle und die Biegestelle sowohl identisch sein als auch an unterschiedlichen Stellen liegen. Wenn die Sollbruchstelle und die Biegestelle identisch sind, müssen mindestens zwei solcher Stellen vorhanden sein, wobei dann der Leiter an einer Stelle in Abhängigkeit von der Inhomogenität des Materials und unterschiedlichem Druck in der Druckwelle zuerst bricht und an der anderen Stelle verformt wird.at a device for the unique and permanent separation of a electrical connection by means of a pressure wave, in particular to carry out the above method is suitable according to the invention has a section an electrical conductor to be cut, both a Predetermined breaking point as well as at least one bending point. there can the predetermined breaking point and the bending point are both identical also in different places. If the breaking point and The bending points are identical, must have at least two such Be present, in which case the conductor at one point in dependence from inhomogeneity of material and different pressure in the pressure wave first breaks and is deformed in the other place.
Es ist zweckmäßig, dass der elektrische Leiter an der Sollbruchstelle und an der Biegestelle mindestens einen Abschnitt mit vermindertem Querschnitt aufweist. Bei einer Ausführungsform erstreckt sich der Leiterabschnitt mit vermindertem Querschnitt über eine vorbestimmte Länge, wobei dieser Leiterabschnitt einen konstanten oder einen sich kontinuierlich verändernden Querschnitt aufweisen kann.It is appropriate that the electrical conductor at the predetermined breaking point and at the bending point has at least one section of reduced cross-section. In one embodiment the conductor section of reduced cross section extends over one predetermined length, this conductor section being a constant or a continuous one changing Cross section may have.
Bei einer zweiten Ausführungsform ist der mindestens eine Abschnitt mit vermindertem Querschnitt keilförmig ausgebildet. Dabei kann der Leiter lediglich an der Sollbruchstelle einen keilförmigen Einschnitt aufweisen, als auch sowohl an der Sollbruchstelle als auch an mindestens einer Biegestelle mindestens einen keilförmigen Einschnitt aufweisen. Die keilförmigen Einschnitte können sowohl auf derselben Seite als auch auf gegenüberliegenden Seiten des Leiters liegen.at a second embodiment the at least one section of reduced cross-section is wedge-shaped. The conductor can only at the breaking point a wedge-shaped incision as well as at the predetermined breaking point as well as at least a bending point have at least one wedge-shaped incision. The wedge-shaped Incisions can both on the same side and on opposite sides of the conductor lie.
Es ist zweckmäßig, dass der Leiter zumindest im Bereich der Sollbruch- und Biegestelle flach ausgebildet ist.It is appropriate that the conductor formed flat at least in the region of the predetermined breaking point and bending point is.
Der Abschnitt des elektrischen Leiters, der durchtrennt werden soll, ist von einem Gehäuse umgeben, in dem bei einem Kraftfahrzeug ein Airbaganzünder angeordnet ist. Es ist zweckmäßig, dass der Airbaganzünder in das Gehäuse eingespritzt ist, so dass beide eine Einheit bilden.The section of the electrical conductor which is to be cut is surrounded by a housing in which an airbag lighter is arranged in a motor vehicle. It is appropriate that the Airbag igniter is injected into the housing, so that both form a unit.
Bei einer Ausführungsform ist der Leiter im Bereich der Trenn- und Biegestelle zwischen einer Buchse und einem Klemmstück gelagert, das ringförmig ausgebildet ist, so dass der Leiter in diese Richtung verform- und trennbar ist.at an embodiment is the conductor in the area of the separation and bending point between a bush and a clamping piece stored, the ring-shaped is formed so that the conductor deformed in this direction and is separable.
