Eine derartige Vorrichtung wird beispielweise zum Auslösen der Sprengladung fur 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" used by motor vehicles, which if necessary to sudden Inflation of the impact bag housed in the steering wheel of a motor vehicle leads. For Repairs and maintenance may require the connection between To disconnect explosive charge and power source. To do this, the mating connector is removed from the connector deducted, which is attached to the line of the explosive charge. Through the then open There is a risk that the explosive charge can be accidentally and accidentally caused by external charges is triggered uncontrollably. That cannot happen.

Aus der GB-A-2 245 775 geht eine Vorrichtung hervor, bei welcher das Kurzschlußelement mit einem Ende im Material des Steckers fixiert ist. Sein anderes Ende ist frei und dadurch federnd verbiegbar. In der Schließstellung der Vorrichtung, in der Stecker und Gegenstecker zusammengefügt sind, ist das Kurzschlußelement durch einen am Gegenstecker angebrachten Stift so weit aus seiner Ruhestellung weggebogen, daß es die Kontaktelemente nicht berührt.From GB-A-2 245 775 a device emerges in which the short-circuit element with one end is fixed in the material of the plug. Its other end is free and therefore springy bendable. In the closed position of the device, in the connector and mating connector are assembled, the short-circuit element is attached by a to the mating connector Pen bent so far out of its rest position that it does not touch the contact elements.

Bei dein aus der US-A-4 894 019 bekannten, eingangs beschriebenen Steckverbinder ist das Kurzschlußelement als Schraubenfeder ausgebildet, deren beide Enden als Arme seitwärts abstehen. Die Schraubenfeder ist auf einem Zapfen eines Trägers angeordnet, der in einer ausreichend großen Ausnehmung des Steckers des Steckverbinders beweglich angeordnet ist. An der Stirnfläche des Gegensteckers ist ein Vorsprung angebracht, der bei zusammengestecktem Steckverbinder an einer Stirnfläche des weit über die Schraubenfeder hinausragenden Trägers anliegt.In the case of the connector described at the beginning of US Pat. No. 4,894,019, this is Short-circuit element designed as a coil spring, the two ends of which as arms sideways stand out. The coil spring is arranged on a pin of a carrier which is in a sufficiently large recess of the plug of the connector is movably arranged. On a protrusion is attached to the end face of the mating connector which, when plugged together Plug connector on one end face of the carrier, which projects far beyond the coil spring is present.

Der Erfindung liegt die Aufgabe zugrunde, den eingangs geschilderten Steckverbinder konstruktiv einfacher zu gestalten.The invention has for its object the connector described above easier to design.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß das als Bügel ausgebildete Kurzschlußelement in seiner Ruhestellung in den für den Gegenstecker in der Schließstellung des Steckverbinders vorgesehenen Raum um eine im Verhältnis zur Länge der als aus dem Stecker herausragende Steckerstifte ausgebildeten Kontaktelemente kürzere Strecke hineinragt,
  • daß das Kurzschlußelement in seiner Arbeitsstellung unter Anlage an der Stirnfläche des auf den Stecker aufgesteckten Gegensteckers im Stecker angeordnet ist und
  • daß die Ausnehmung des Steckers im Bereich ihrer Öffnung durch als Anlageflächen für das Kurzschlußelement dienende Schrägen nach außen konisch erweitert ist.
According to the invention, this object is achieved by
  • that the short-circuit element designed as a bracket projects in its rest position into the space provided for the mating connector in the closed position of the connector by a shorter distance in relation to the length of the contact elements formed as connector pins protruding from the connector,
  • that the short-circuit element is arranged in its working position, bearing against the end face of the mating connector plugged into the connector, and
  • that the recess of the plug is flared outwards in the region of its opening by bevels serving as contact surfaces for the short-circuit element.

Bei diesem Steckverbinder ist der Stromkreis einer an die Leitung des Steckers angeschlossenen 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 Kontaktelemente 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 Kontaktelementen sind. In der Arbeitsstellung ist das Kurzschlußelement so weit in den Stecker zurückgedrängt, daß es die Kontaktelemente 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 Kontaktelemente 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 connector, the circuit is one connected to the line of the connector Explosive charge automatically short-circuited if no mating connector is plugged into the connector is. The explosive charge can then no longer be triggered by external charges. Reached is the short-circuit element arranged in the plug, which by its shape and its spring force then short-circuits the two contact elements when the mating connector is not at all or at least not completely plugged into the connector. The short circuit element is only moved from its rest position by the mating connector when its contacts already are in contact with the contact elements. In the working position, the short-circuit element is like this pushed far back into the connector so that it no longer touches the contact elements. If the Mating connector is withdrawn from the connector, the short-circuit element follows because of it Shape and spring force of the movement of the mating connector. It then closes in its Rest position the two contact elements just before the mating connector is completely off deducted the same. In this way it is ensured that the circuit of the Explosive charge is never open. It is either short-circuited or by the Mating connector occupied. The short-circuit element also places between the rest position and Working position only a short way back, so that its effectiveness is quick is guaranteed.

Vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous embodiments of the invention emerge from the subclaims.

Ein Ausführungsbeispiel des Erfindungsgegenständes ist in den Zeichnungen dargestellt.An embodiment of the subject of the invention is shown in the drawings.

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 which can be triggered by an electric current and which has a two-wire electrical line 2 is connected to a power source 3. In line 2 is one Coupling consisting of connector 4 and mating connector 5 attached. The connector 4 is located on the side of the explosive charge 1, while the mating connector 5 on the side of the power source 3 is arranged.

Der Stecker 4 besteht gemäß Fig. 2 aus einem Isolierkörper 6, in dem zwei als Steckerstifte ausgebildete Kontaktelemente 7 und 8 angebracht sind. Der Einfachheit halber wird im folgenden die Bezeichnung "Steckerstifte 7 und 8" verwendet. 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 as plug pins trained contact elements 7 and 8 are attached. For the sake of simplicity, the following is the designation "connector pins 7 and 8" used. At the connector pins 7 and 8 are the electrical conductor of the two wires 9 and 10 of the electrical line 2 connected. in the Plug 4 or in its insulating body 6, a short-circuit element 11 is attached. It is in the Area between the two connector pins 7 and 8.

Das Kurzschlußelement 11 ist 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. des Steckverbinders 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 as an approximately V-shaped bracket, as is shown in FIG. 2 is shown. At its free ends it has an approximately semicircular curve towards the outside pointing bend 12 or 13. The short-circuit element 11 is made of resilient metal, for example made of steel. In the open position of the plug 4 and the illustrated in FIG. 2 Connector is the short-circuit element 11 in its rest position, which it due to its Shape and its spring force. It looms in relation to the length of the Connector pins 7 and 8 shorter piece into the space provided for the mating connector 5 and lies with its bends 12 and 13 on the connector pins 7 and 8. The connector pins 7 and 8 are short-circuited as well as the circuit of the explosive charge. For Improvement of the contact between short-circuit element 11 and pins 7 and 8 can the surfaces of the short-circuit element 11 be gold-plated, which abut the connector pins 7 and 8.

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 in accordance with the illustration in FIGS. 2 to 4 Recess 14 of the plug 4 and the insulating body 6 attached. The recess 14 has an opening that lies between the connector pins 7 and 8. In the area of the opening is the Recess 14 flared by two bevels 15 and 16, which serve as contact surfaces for the Bends 12 and 13 of the short-circuit element 11 serve. In the recess 14 is a Stop 17 attached to limit the movement of the short-circuit element 11 to the outside. As a result, it is held captively in the plug 4.

Der Kurzschluß der Steckerstifte 7 und 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 - beispielweise 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 connector pins 7 and 8 remains until the short circuit element 11 is moved from its rest position by the mating connector 5. The mating connector 5 becomes Establishing the conductive connection between explosive charge 1 and current source 3 on the Plug pins 7 and 8 attached. His contacts - for example sockets - already have this Contact with the connector pins 7 and 8 before the end face 18 of the mating connector 5 Short-circuit element 11 touches. This position is shown in Fig. 3. The lead connection between connector 4 and mating connector 5 is thus already made before that Short-circuit element 11 is moved.

Wenn der Gegenstecker 5 dann in seine aus Fig 4 ersichtliche, der Schließstellung des Steckverbinders 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 5 von denselben abgezogen wird.If the mating connector 5 then in its apparent from Fig. 4, the closed position of the Is brought connector corresponding end position, the short-circuit element 11 in his working position shifted, in which there is no longer contact with the connector pins 7 and 8 Has. Its bends 12 and 13 slide on the slopes 15 and 16 of the recess 14 along, so that the short-circuit element 11 is compressed against its spring force becomes. It automatically slips back into its rest position shown in FIG. 2 as soon as the Mating connector 5 pulled out of connector 4 and thus from connector pins 7 and 8 is subtracted. The short-circuit element 11 travels a very short distance. It lies already on the connector pins 7 and 8 before the mating connector 5 of the same is subtracted.
