Abstract

A device is specified for the connection of an explosive charge, which can be triggered by electrical current, to a current source, in the case of which device a two-wire electrical cable is connected to the explosive charge. A plug (4) having two plug pins (7, 8) which run parallel to one another and onto which a mating plug is plugged when the device is in the closed position is fitted on that end of the cable facing away from the explosive charge. A short-circuiting element (11) is fitted in the region between the two plug pins (7, 8). This short-circuiting element (11) consists of resilient metal and is arranged such that it can move in the plug (4) in the direction of the axis of the plug pins (7, 8), between a defined rest position and an operating position. In its rest position, which is predetermined by its own shape and spring force and corresponds to the device being in the open position, the short-circuiting element (11) projects into the space which is provided for mating the plug when the device is in the closed position, making contact with both plug pins (7, 8), by a distance which is shorter than the length of the plug pins (7, 8). In its operating position, it is arranged in a recess (14) in the plug (4), making contact on the end surface of the mating plug, which is located in the closed position of the device, without touching the plug pins (7, 8). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Verbinden einer durch elektrischen Strom auslösbaren Sprengladung mit einer Stromquelle, bei welcher an die Sprengladung eine zweiadrige elektrische Leitung angeschlossen ist, an deren der Sprengladung abgewandtem Ende ein Stecker mit zwei parallel zueinander verlaufenden Steckerstiften angebracht ist, auf den in der Schließstellung der Vorrichtung ein Gegenstecker aufgesteckt ist, während die Steckerstifte in der Offenstellung der Vorrichtung frei vom Gegenstecker sind.The invention relates to a device for connecting an explosive charge which can be triggered by electrical current to a power source, in which a two-wire electrical line is connected to the explosive charge, on the end of which is remote from the explosive charge, a plug having two plug pins running parallel to one another is attached to the a mating connector is inserted in the closed position of the device, while the connector pins are free of the mating connector in the open position of the device.

Eine derartige Vorrichtung wird beispielsweise zum Auslösen der Sprengladung für den sogenannten "Airbag" von Kraftfahrzeugen verwendet, die im Bedarfsfall zum schlagartigen Aufblasen des im Lenkrad eines Kraftfahrzeuges untergebrachten Prallsacks führt. Für Reparaturzwecke und Wartungsarbeiten kann es erforderlich sein, die Verbindung zwischen Sprengladung und Stromquelle aufzutrennen. Dazu wird der Gegenstecker von dem Stecker abgezogen, der an der Leitung der Sprengladung angebracht ist. Durch das dann offene Leitungsende besteht die Gefahr, daß die Sprengladung durch Fremdladungen versehentlich und unkontrolliert ausgelöst wird. Das darf nicht geschehen.Such a device is used, for example, to trigger the explosive charge for the so-called "airbag" of motor vehicles, which if necessary leads to the sudden inflation of the impact bag accommodated in the steering wheel of a motor vehicle. For repair purposes and maintenance work, it may be necessary to disconnect the connection between the explosive charge and the power source. To do this, the mating connector is removed from the connector that is attached to the line of the explosive charge. Due to the then open end of the line, there is a risk that the explosive charge is triggered accidentally and uncontrollably by external charges. That cannot happen.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Vorrichtung so zu gestalten, daß die Sprengladung vor einer Beeinflussung durch Fremdladungen geschützt ist.The invention has for its object to design the device described above so that the explosive charge is protected from interference by external charges.

Diese Aufgabe wird gemäß der Erfindung dadurch ausgelöst,

  • daß im Bereich zwischen den beiden Steckerstiften ein aus federndem Metall bestehendes Kurzschlußelement angebracht ist, das in Richtung der Achse der Steckerstifte zwischen einer definierten Ruhestellung und einer Arbeitsstellung bewegbar im Stecker angeordnet ist,
  • daß das Kurzschlußelement in seiner durch eigene Formgebung und Federkraft vorgegebenen, der Offenstellung der Vorrichtung entsprechenden Ruhestellung unter Anlage an beiden Steckerstiften in den für den Gegenstecker in der Schließstellung der Vorrichtung vorgesehenen Raum um eine im Verhältnis zur Länge der Steckerstifte kürzere Strecke hineinragt und
  • daß das Kurzschlußelement in seiner Arbeitsstellung unter Anlage an der Stirnfläche des in der Schließstellung der Vorrichtung befindlichen Gegensteckers ohne Berührung der Steckerstifte im Stecker angeordnet ist.
According to the invention, this object is achieved by
  • that a short-circuit element made of resilient metal is attached in the area between the two connector pins and is arranged in the connector so as to be movable in the direction of the axis of the connector pins between a defined rest position and a working position,
  • that the short-circuit element in its predetermined shape and spring force, corresponding to the open position of the device, rests on both connector pins in the space provided for the mating connector in the closed position of the device by a shorter distance in relation to the length of the connector pins and
  • that the short-circuit element is arranged in its working position, bearing against the end face of the mating connector located in the closed position of the device, without touching the connector pins in the connector.

Bei dieser Vorrichtung ist der Stromkreis der Sprengladung automatisch kurzgeschlossen, wenn auf den Stecker kein Gegenstecker aufgesteckt ist. Die Sprengladung kann dann nicht mehr durch Fremdladungen ausgelöst werden. Erreicht wird das durch das im Stecker angeordnete Kurzschlußelement, das durch seine Formgebung und seine Federkraft die beiden Steckerstifte dann kurzschließt, wenn der Gegenstecker gar nicht oder zumindest nicht vollständig auf den Stecker aufgesteckt ist. Das Kurzschlußelement wird durch den Gegenstecker erst dann aus seiner Ruhestellung bewegt, wenn dessen Kontakte bereits in Berührung mit den Steckerstiften sind. In der Arbeitsstellung ist das Kurzschlußelement so weit in den Stecker zurückgedrängt, daß es die Steckerstifte nicht mehr berührt. Wenn der Gegenstecker vom Stecker abgezogen wird, folgt das Kurzschlußelement wegen seiner Formgebung und Federkraft der Bewegung des Gegensteckers. Es schließt dann in seiner Ruhestellung die beiden Steckerstifte kurz, bevor der Gegenstecker vollständig von denselben abgezogen ist. Es ist auf diese Weise sichergestellt, daß der Stromkreis der Sprengladung zu keiner Zeit offen ist. Er ist entweder kurzgeschlossen oder durch den Gegenstecker belegt. Das Kurzschlußelement legt außerdem zwischen Ruhestellung und Arbeitsstellung einen nur kurzen Weg zurück, so daß eine schnelle Wirksamkeit desselben garantiert ist.In this device, the circuit of the explosive charge is automatically short-circuited if no mating connector is plugged into the connector. The explosive charge can then no longer be triggered by external charges. This is achieved by the short-circuit element arranged in the plug, which then short-circuits the two plug pins due to its shape and its spring force if the mating plug is not or at least not completely plugged onto the plug. The short-circuit element is only moved out of its rest position by the mating connector when its contacts are already in contact with the connector pins. In the working position, the short-circuit element is pushed back so far into the connector that it no longer touches the connector pins. When the mating connector is removed from the connector, the short-circuit element follows the movement of the mating connector because of its shape and spring force. It then short-circuits the two connector pins in its rest position before the mating connector is completely removed from the same. This ensures that the explosive charge circuit is never open. It is either short-circuited or occupied by the mating connector. The short-circuit element also travels only a short distance between the rest position and the working position, so that its rapid effectiveness is guaranteed.

Mit 1 ist eine durch elektrischen Strom auslösbare Sprengladung bezeichnet, die über eine zweiadrige elektrische Leitung 2 mit einer Stromquelle 3 verbunden ist. In der Leitung 2 ist eine aus Stecker 4 und Gegenstecker 5 bestehende Kupplung angebracht. Der Stecker 4 befindet sich auf der Seite der Sprengladung 1, während der Gegenstecker 5 auf der Seite der Stromquelle 3 angeordnet ist.1 denotes an explosive charge that can be triggered by electrical current and is connected to a current source 3 via a two-wire electrical line 2. A coupling consisting of plug 4 and mating plug 5 is attached in line 2. The connector 4 is located on the side of the explosive charge 1, while the mating connector 5 is arranged on the side of the power source 3.

Der Stecker 4 besteht gemäß Fig. 2 aus einem Isolierkörper 6, in dem zwei Steckerstifte 7 und 8 angebracht sind. An die Steckerstifte 7 und 8 sind die elektrischen Leiter der beiden Adern 9 und 10 der elektrischen Leitung 2 angeschlossen. Im Stecker 4 bzw. in dessen Isolierkörper 6 ist ein Kurzschlußelement 11 angebracht. Es liegt im Bereich zwischen den beiden Steckerstiften 7 und 8.2 consists of an insulating body 6, in which two connector pins 7 and 8 are attached. The electrical conductors of the two wires 9 and 10 of the electrical line 2 are connected to the plug pins 7 and 8. A short-circuit element 11 is attached in the plug 4 or in its insulating body 6. It lies in the area between the two connector pins 7 and 8.

Das Kurzschlußelement 11 ist beispielsweise als etwa V-förmiger Bügel ausgeführt, so wie es in Fig. 2 dargestellt ist. Es hat an seinen freien Enden je eine etwa halbkreisförmig gebogene, nach außen weisende Ausbiegung 12 bzw. 13. Das Kurzschlußelement 11 besteht aus federndem Metall, beispielsweise aus Stahl. In der in Fig. 2 dargestellten Offenstellung des Steckers 4 bzw. der Vorrichtung liegt das Kurzschlußelement 11 in seiner Ruhestellung, die es aufgrund seiner Formgebung und seiner Federkraft einnimmt. Es ragt dabei um ein im Verhältnis zur Länge der Steckerstifte 7 und 8 kürzeres Stück in den für den Gegenstecker 5 vorgesehenen Raum hinein und liegt mit seinen Ausbiegungen 12 und 13 an den Steckerstiften 7 und 8 an. Die Steckerstifte 7 und 8 sind dadurch ebenso wie der Stromkreis der Sprengladung kurzgeschlossen. Zur Verbesserung des Kontaktes zwischen Kurzschlußelement 11 und Steckerstiften 7 und 8 können die Flächen des Kurzschlußelements 11 vergoldet sein, die an den Steckerstiften 7 und 8 anliegen.The short-circuit element 11 is designed, for example, as an approximately V-shaped bracket, as shown in FIG. 2. It has at its free ends an approximately semicircularly curved, outwardly facing bend 12 and 13. The short-circuit element 11 is made of resilient metal, for example steel. In the open position of the plug 4 or the device shown in FIG. 2, the short-circuit element 11 is in its rest position, which it assumes due to its shape and its spring force. It protrudes by a shorter piece in relation to the length of the connector pins 7 and 8 into the space provided for the mating connector 5 and bears with its bends 12 and 13 against the connector pins 7 and 8. The plug pins 7 and 8 are short-circuited as well as the circuit of the explosive charge. To improve the contact between the short-circuit element 11 and the plug pins 7 and 8, the surfaces of the short-circuit element 11, which bear against the plug pins 7 and 8, can be gold-plated.

Das Kurzschlußelement 11 ist entsprechend der Darstellung in den Fig. 2 bis 4 in einer Ausnehmung 14 des Steckers 4 bzw. des Isolierkörpers 6 angebracht. Die Ausnehmung 14 hat eine Öffnung, die zwischen den Steckerstiften 7 und 8 liegt. Im Bereich der Öffnung ist die Ausnehmung 14 durch zwei Schrägen 15 und 16 konisch erweitert, die als Anlageflächen für die Ausbiegungen 12 und 13 des Kurzschlußelements 11 dienen. In der Ausnehmung 14 ist ein Anschlag 17 zur Begrenzung der Bewegung des Kurzschlußelements 11 nach außen angebracht. Es ist dadurch unverlierbar im Stecker 4 gehalten.The short-circuit element 11 is attached as shown in FIGS. 2 to 4 in a recess 14 of the plug 4 or the insulating body 6. The recess 14 has an opening which lies between the connector pins 7 and 8. In the area of the opening, the recess 14 is flared by two bevels 15 and 16, which serve as contact surfaces for the bends 12 and 13 of the short-circuit element 11. A stop 17 for limiting the movement of the short-circuit element 11 to the outside is attached in the recess 14. As a result, it is held captively in the plug 4.

Der Kurzschluß der Steckerstifte 7 un 8 bleibt solange bestehen, bis das Kurzschlußelement 11 durch den Gegenstecker 5 aus seiner Ruhestellung bewegt wird. Der Gegenstecker 5 wird zur Herstellung der leitenden Verbindung zwischen Sprengladung 1 und Stromquelle 3 auf die Steckerstifte 7 und 8 aufgesteckt. Dabei haben seine Kontakte - beispielsweise Buchsen - bereits Berührung mit den Steckerstiften 7 und 8 bevor die Stirnfläche 18 des Gegensteckers 5 das Kurzschlußelement 11 berührt. Diese Position ist in Fig. 3 dargestellt. Die leitende Verbindung zwischen Stecker 4 und Gegenstecker 5 ist damit also bereits hergestellt, bevor das Kurzschlußelement 11 bewegt wird.The short circuit of the plug pins 7 and 8 remains until the short-circuit element 11 is moved out of its rest position by the mating connector 5. The mating connector 5 is plugged onto the connector pins 7 and 8 to establish the conductive connection between the explosive charge 1 and the current source 3. Its contacts - for example sockets - are already in contact with the plug pins 7 and 8 before the end face 18 of the mating connector 5 touches the short-circuit element 11. This position is shown in Fig. 3. The conductive connection between connector 4 and mating connector 5 is thus already established before the short-circuit element 11 is moved.

Wenn der Gegenstecker 5 dann in seine aus Fig. 4 ersichtliche, der Schließstellung der Vorrichtung entsprechende Endposition gebracht wird, wird das Kurzschlußelement 11 in seine Arbeitsstellung verschoben, in der es keinen Kontakt mehr mit den Steckerstiften 7 und 8 hat. Seine Ausbiegungen 12 und 13 gleiten dabei auf den Schrägen 15 und 16 der Ausnehmung 14 entlang, so daß das Kurzschlußelement 11 entgegen seiner Federkraft zusammengedrückt wird. Es rutscht automatisch in seine aus Fig. 2 ersichtliche Ruhestellung zurück, sobald der Gegenstecker 5 aus dem Stecker 4 herausgezogen und damit von den Steckerstiften 7 und 8 abgezogen wird. Dabei legt das Kurzschlußelement 11 einen sehr kurzen Weg zurück. Es liegt bereits wieder an den Steckerstiften 7 und 8 an, bevor der Gegenstecker von denselben abgezogen wird.When the mating connector 5 is then brought into its end position, which can be seen in FIG. 4 and corresponds to the closed position of the device, the short-circuit element 11 is moved into its working position in which it no longer has any contact with the connector pins 7 and 8. Its bends 12 and 13 slide along the slopes 15 and 16 of the recess 14 so that the short-circuit element 11 is compressed against its spring force. It automatically slips back into its rest position shown in FIG. 2 as soon as the mating connector 5 is pulled out of the connector 4 and thus removed from the connector pins 7 and 8. The short-circuit element 11 travels a very short distance. It is already back on the connector pins 7 and 8 before the mating connector is removed from the same.
