Description

Die Erfindung betrifft eine Anzündeinrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to an ignition device according to the preamble of claim 1.

Aus der DE-OS 36 06 364 ist ein elektrischer Zündbrückenträger zur Anzündung von Anzündsätzen, Verzögerungssätzen und pyrotechnischen Mischungen sowie zur Zündung von Primärzündstoffen und -sätzen bekannt. Der Zündbrückenträger bzw. diese Anzündeinrichtung weist ein metallisches Aufnahmeteil mit einer zylindrischen Ausnehmung auf, in der ein Keramikkörper eingebracht ist. Dieser Keramikkörper ist mit zwei Bohrungen versehen, in die jeweils ein massiver, rohrförmiger Kontaktstift fest und dicht eingepaßt ist. Auf der Anschlußseite ragen diese Kontaktstifte aus dem Keramikkörper heraus, während sie auf der Anzündseite über eine Zündbrücke miteinander verbunden sind. Angrenzend an die Zündbrücke ist ein Anzündsatz im Aufnahmeteil angeordnet. Bei der Zündung wird eine solch hohe Spannung an die Kontaktstifte gelegt, daß die Zündbrücke schlagartig verbrennt, wodurch der Anzündsatz gezündet wird.From DE-OS 36 06 364 an electrical ignition bridge carrier for igniting primer sets, delay sets and pyrotechnic mixtures and for igniting primary primers and sets is known. The ignition bridge carrier or this ignition device has a metallic receiving part with a cylindrical recess in which a ceramic body is introduced. This ceramic body is provided with two bores, in each of which a solid, tubular contact pin is firmly and tightly fitted. On the connection side, these contact pins protrude from the ceramic body, while they are connected to one another on the ignition side via an ignition bridge. An ignition charge is arranged in the receiving part adjacent to the ignition bridge. During ignition, such a high voltage is applied to the contact pins that the ignition bridge burns suddenly, which ignites the ignition charge.

Derartige Anzündeinrichtungen können z.B. in Druckelemente für den Einsatz in Gurtstraffern, Schloßstraffern oder in Gurtaufrollern von Kraftfahrzeugen benutzt werden. Bei einem Unfall wird die Anzündeinrichtung durch einen Sensor ausgelöst, wodurch im Druckelement ein Gas erzeugt wird, welches z.B. einen Kolben bewegt. Der Kolben ist mit einem Seil am Gurtschloß bzw. mit einem Automatikgurtaufroller verbunden und strafft den Gurt.Such igniters can e.g. be used in pressure elements for use in belt tensioners, buckle tensioners or in belt retractors of motor vehicles. In the event of an accident, the ignition device is triggered by a sensor, whereby a gas is generated in the pressure element, which e.g. moved a piston. The piston is connected to the belt buckle by a rope or to an automatic belt retractor and tightens the belt.

Nachteilig an der beschriebenen Anzündeinrichtung ist, daß durch von außen induzierte elektrische Felder eine elektrostatische Aufladung zwischen den Kontaktstiften und dem Gehäuse auftreten kann, die bei Entladung zum ungewollten Zünden des Anzündsatzes führen kann.A disadvantage of the igniter described is that an electrostatic charge can occur between the contact pins and the housing due to externally induced electric fields, which can lead to undesired ignition of the igniter charge when discharged.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Anzündeinrichtung nach dem Oberbegriff des Anspruchs 1 derart weiterzubilden, daß bei elektrostatischen Entladungen zwischen den Kontaktstiften und dem Gehäuse kein Zünden des Anzündsatzes erfolgt.The invention is therefore based on the object of developing an ignition device according to the preamble of claim 1 such that no ignition of the ignition charge takes place in the event of electrostatic discharges between the contact pins and the housing.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Aufnahmeteil mit Kunststoff umspritzbar und in ein Gehäuse einsetzbar ist, daß am Aufnahmeteil eine erste Umfangserweiterung vorgesehen ist, die mit dem ersten Kontaktstift elektrisch leitend verbunden ist, daß am Aufnahmeteil eine zweite Umfangserweiterung vorgesehen ist, die unter geringer Freistellung bis an das Gehäuse heranreichend ausbildbar ist und deren äußeres Ende nicht mit Kunststoff umspritzt ist.According to the invention, this object is achieved in that the receiving part can be encapsulated with plastic and inserted into a housing, that a first circumferential extension is provided on the receiving part, which is electrically conductively connected to the first contact pin, that a second circumferential extension is provided on the receiving part, which is provided under low exemption can be trained up to the housing and the outer end is not encapsulated with plastic.

Dadurch, daß der erste Kontaktstift mit dem Aufnahmeteil leitend verbunden ist und das Aufnahmeteil über die zweite Umfangserweiterung bis an das Gehäuse heranreicht, findet eine etwaige elektrostatische Entladung zwischen dieser zweiten Umfangserweiterung und dem Gehäuse und damit weit weg von den Anzündsätzen statt. Durch den Kunststoffkörper ist das Aufnahmeteil sicher und leicht zu handhaben. Das Gehäuse ist elektrisch leitend ausgebildet.Because the first contact pin is conductively connected to the receiving part and the receiving part extends over the second circumferential extension to the housing, any electrostatic discharge takes place between this second circumferential extension and the housing and thus far away from the ignition sets. Due to the plastic body, the receiving part is safe and easy to handle. The housing is designed to be electrically conductive.

Vorteilhafterweise ist der erste Kontaktstift mit der ersten Umfangserweiterung durch Schweißung, Lötung bzw. Nietung verbunden. Hierdurch ist eine dauerhafte und optimale Verbindung erreicht.The first contact pin is advantageously connected to the first circumferential extension by welding, soldering or riveting. This ensures a permanent and optimal connection.

In bevorzugter erfindungsgemäßer Ausführungsform ist im Aufnahmeteil ein Metallschichtelement mit einer Zündbrücke angeordnet. Ein derartiges Metallschichtzündmittel bzw. Metallschichtelement ist Stand der Technik und z.B. in der DE-PS 20 20 016 beschrieben. Diese Metallschichtelemente sind kostengünstig herzustellen und liefern genau definierte Zündbrücken.In a preferred embodiment according to the invention, a metal layer element with an ignition bridge is arranged in the receiving part. Such a metal layer primer or metal layer element is state of the art and described, for example, in DE-PS 20 20 016. These metal layer elements are inexpensive to manufacture and deliver precisely defined ones Ignition bridges.

Zweckmäßigerweise ist der zweite Kontaktstift im Metallschichtelement elektrisch leitend verankert. Dies kann z.B. durch Lötung geschehen. Die Zündbrücke befindet sich zwischen diesem zweiten Kontaktstift und dem Aufnahmeteil bzw. dem ersten Kontaktstift auf dem Metallschichtelement. Dieser erste Kontaktstift bildet somit die andere Anschlußelektrode.The second contact pin is expediently anchored in an electrically conductive manner in the metal layer element. This can e.g. done by soldering. The ignition bridge is located between this second contact pin and the receiving part or the first contact pin on the metal layer element. This first contact pin thus forms the other connection electrode.

In bevorzugter Ausführungsform sind die erste und die zweite Umfangserweiterung in bezug auf die Längsachse des Aufnahmeteils diametral gegenüberliegend angeordnet.In a preferred embodiment, the first and the second circumferential extension are arranged diametrically opposite one another with respect to the longitudinal axis of the receiving part.

Zweckmäßigerweise ist das Aufnahmeteil zylinderförmig und aus Messing gefertigt und ist mit Polyamid umspritzt.The receiving part is expediently cylindrical and made of brass and is extrusion-coated with polyamide.

In bevorzugter Ausführungsform ist die Anzündeinrichtung in ein mit einem gaserzeugenden Stoff geladenes Gehäuse eingebaut.In a preferred embodiment, the ignition device is installed in a housing loaded with a gas-generating substance.

In einer alternativen Ausgestaltung ist vorteilhafterweise zwischen Kunststoffkörper und Aufnahmeteil im Bereich der Anzündsätze eine ringförmige Ausnehmung vorgesehen. Durch diese Ausnehmung wird beim Zünden der mechanische Impuls nicht direkt in den Kunststoffmantel eingeleitet.In an alternative embodiment, an annular recess is advantageously provided between the plastic body and the receiving part in the area of the igniter charges. Through this recess, the mechanical impulse is not introduced directly into the plastic jacket during ignition.

Zweckmäßigerweise sind die Umfangserweiterungen an dem den Anzündsätzen entgegengesetzen Ende des Aufnahmeteils angeordnet. Die Umfangserweiterungen sind dabei bevorzugt laschen-, lappen-, stegförmig oder dergleichen ausgebildet und erstrecken sich im wesentlichen radial zur Längsachse des Aufnahmeteils. Es kann jedoch auch vorteilhaft sein, wenn die Umfangserweiterungen ineinander übergehen, d.h. einen Ringbund oder einen Ringflansch bilden.The circumferential expansions are expediently arranged at the end of the receiving part that is opposite to the ignition charges. The circumferential extensions are preferably designed in the form of tabs, lobes, webs or the like and extend essentially radially to the longitudinal axis of the receiving part. However, it can also be advantageous if the circumferential extensions merge into one another, ie form an annular collar or an annular flange.

Weitere Merkmale der Erfindung ergeben sich aus den Zeichnungen, die nachfolgend beschrieben sind.Further features of the invention emerge from the drawings, which are described below.

Figur 1 zeigt eine Anzündeinrichtung 1 mit einem mit einem Kunststoffkörper 13 versehenen Aufnahmeteil 2. Figur 1a zeigt dabei einen Längsschnitt und Figur 1b eine Draufsicht. In den Figuren 2a, 2b ist das identische Aufnahmeteil 2, jedoch ohne Anzündsätze und Kunststoffkörper gezeigt.Figure 1 shows an ignition device 1 with a receiving part 2 provided with a plastic body 13. Figure 1a shows a longitudinal section and Figure 1b shows a plan view. FIGS. 2a, 2b show the identical receiving part 2, but without ignition kits and plastic bodies.

Das Aufnahmeteil 2 ist zylinderförmig ausgebildet und ist aus Metall (z.B. Messing) gefertigt. An seinem einen Ende ist ein Metallschichtelement 10 in das Aufnahmeteil 2 eingesetzt. Im Bereich des Metallschichtelementes 10 weist das Aufnahmeteil 2 eine geringfügige Umfangserweiterung auf. Auf dem Metallschichtelement 10 befindet sich die Zündbrücke, die mit einem Pol mit dem Gehäuse des Aufnahmeteils 2 elektrisch leitend verbunden ist. An seinem, dem Metallschichtelement zugewandten Ende des Aufnahmeteils 2 sind zwei in bezug auf die Längsachse 11 diametral gegenüberliegende, lappenförmige Umfangserweiterungen 8, 9 angeordnet. Diese Umfangserweiterungen 8, 9 erstrecken sich im rechten Winkel zum Gehäuse des Aufnahmeteils 2 und verlaufen an ihrer unteren Seite bündig mit der dort angeordneten unteren Stirnseite des Metallschichtelementes 10. Ein erster Kontaktstift 3 ist in die erste Umfangserweiterung 8 eingenietet bzw. angeschweißt, vorteilhafterweise eingelötet, und erstreckt sich parallel zur Längsachse 11 des Aufnahmeteils 2. Ein zweiter Kontaktstift 4 ist in das Metallschichtelement 10 eingesetzt und liegt mit einem Flansch 14 zur Begrenzung der Tiefe des Einschubes an der unteren Stirnseite des Metallschichtelementes 10 auf. Dieser zweite Kontaktstift 4 ist auf der Längsachse des Aufnahmeteils 2 angeordnet.The receiving part 2 is cylindrical and is made of metal (eg brass). A metal layer element 10 is inserted into the receiving part 2 at one end. In the area of the metal layer element 10, the receiving part 2 has a slight circumferential expansion. The ignition bridge is located on the metal layer element 10 and is connected to the housing of the receiving part 2 in an electrically conductive manner with a pole. At its end of the receiving part 2 facing the metal layer element there are two diametrically opposite, with respect to the longitudinal axis 11, lobe-shaped circumferential extensions 8, 9 arranged. These circumferential extensions 8, 9 extend at right angles to the housing of the receiving part 2 and run flush on their lower side with the lower end face of the metal layer element 10 arranged there. A first contact pin 3 is riveted or welded into the first circumferential extension 8, advantageously soldered in, and extends parallel to the longitudinal axis 11 of the receiving part 2. A second contact pin 4 is inserted into the metal layer element 10 and lies on the lower end face of the metal layer element 10 with a flange 14 for limiting the depth of the insert. This second contact pin 4 is arranged on the longitudinal axis of the receiving part 2.

Fig. 2b zeigt die Anordnung und Ausbildung der lappenförmigen Umfangserweiterungen 8, 9.2b shows the arrangement and design of the lobe-shaped circumferential extensions 8, 9.

Auf dem Metallschichtelement 10 innerhalb des Aufnahmeteils 2 ist ein erster Anzündsatz 5 und darüber ein zweiter Anzündsatz 6 angeordnet (siehe Fig. 1a). Der zweite Anzündsatz 6 ist mit einer Schutzschicht bzw. Abdeckung 15 versehen. In der Mitte des zweiten Anzündsatzes 6 ist eine Bombierung 16 angeordnet.A first ignition charge 5 and a second ignition charge 6 are arranged on the metal layer element 10 within the receiving part 2 (see FIG. 1a). The second ignition charge 6 is provided with a protective layer or cover 15. A crown 16 is arranged in the middle of the second ignition charge 6.

Das Aufnahmeteil 2 ist mit einem Kunststoffkörper 13 aus Polyamid umgeben. Es kann jedoch auch ein anderer Kunststoff (z.B. Polyethersulfon) oder Verbundwerkstoff verwendet werden. Aus dem Kunststoffkörper 13 ragt das Aufnahmeteil 2 mit seinem oberen Ende, die Kontaktstifte 3, 4 und die zweite Umfangserweiterung 9 mit ihrem Ende heraus. Mit "oben" ist grundsätzlich die Anzündseite und mit "unten" die elektrische Anschlußseite verstanden.The receiving part 2 is surrounded by a plastic body 13 made of polyamide. However, another plastic (e.g. polyether sulfone) or composite material can also be used. The receiving part 2 protrudes from the plastic body 13 with its upper end, the contact pins 3, 4 and the second circumferential extension 9 with its end. "Top" basically means the ignition side and "bottom" the electrical connection side.

Die zweite Umfangserweiterung 9 ragt dabei bis nahe an die äußere Umfangswandung des Kunststoffkörpers 13 heran. Am unteren Ende des Kunststoffkörpers 13 ist ein Schuh 17, den Kontaktstiften 3, 4 benachbart, angeordnet, der zur Befestigung von bekannten Steckern bzw. Anschlußbuchsen dient. Diese Anschlußbuchse schließt bei nicht eingestecktem Stecker die beiden Kontaktstifte 3, 4 kurz.The second circumferential extension 9 projects close to the outer circumferential wall of the plastic body 13. At the lower end of the plastic body 13, a shoe 17, the contact pins 3, 4 adjacent, is arranged, which is used to attach known plugs or sockets. This connector shorts the two contact pins 3, 4 when the plug is not inserted.

Oberhalb des Schuhs 17 ist ein Flansch 18 mit einer Kerbe 19 angeordnet. Der Flansch 18 dient zum Einbau der Anzündeinrichtung 1 in ein Druckelementgehäuse (siehe Fig. 3). Mit der Kerbe 19 läßt sich die Anzündeinrichtung 1 im Produktionsprozeß positionieren. Oberhalb der zweiten Umfangserweiterung 9 ist auf der Außenwand des Kunststoffkörpers 13 eine Ringdichtung 20 als O-Ring ausgebildet, angeordnet.A flange 18 with a notch 19 is arranged above the shoe 17. The flange 18 is used to install the ignition device 1 in a pressure element housing (see FIG. 3). The ignition device 1 can be positioned with the notch 19 in the production process. Above the second circumferential extension 9, an annular seal 20 designed as an O-ring is arranged on the outer wall of the plastic body 13.

Fig. 3 zeigt die Anzündeinrichtung 1 gemäß den Figuren 1, 2 eingebaut in ein Druckelement 12. Das Gehäuse 7 des Druckelementes 12 umgibt dabei die Anzündeinrichtung 1 nahezu vollständig und liegt an der Außenwandung des Kunststoffkörpers 13 an. Oberhalb der Anzündeinrichtung bildet das Gehäuse 7 des Druckelementes 12 einen Hohlraum, in dem eine gaserzeugende Ladung 21 angeordnet ist, die an ihrer unteren Seite durch eine Abdeckfolie 22 geschützt ist. An der oberen Stirnseite weist das Gehäuse 7 eine Sollbruchstelle 23 auf, durch die das freigesetzte Gas das Druckelement 12 verlassen kann. Der schon weiter oben beschriebene Flansch 18 liegt an einer Kante des Gehäuses 7 an, wobei ein Konus in einem Teil 24 den Flansch 18 und damit die Anzündeinrichtung dichtend gegen das Gehäuse 7 drückt. Am unteren Ende der Anzündeinrichtung ist eine bekannte Kurzschlußbuchse 25 gezeigt, die bei nicht eingestecktem Stecker die beiden Kontaktstifte 3, 4 kurzschließt. Erfindungsgemäß ragt die lappenförmige zweite Umfangserweiterung 9 bis nahe an das Gehäuse 7 des Druckelementes 12 heran. Bei elektrostatischen Aufladungen zwischen einem Kontaktstift 3, 4 und dem Gehäuse 7 findet daher ein Spannungsüberschlag in einer Zone statt, die weit von den Anzündsätzen 5, 6 in der Anzündeinrichtung 1 entfernt ist. Diese Anordnung bildet somit einen Schutz gegen elektrostatische Entladungen.FIG. 3 shows the ignition device 1 according to FIGS. 1, 2 installed in a pressure element 12. The housing 7 of the pressure element 12 surrounds the ignition device 1 almost completely and lies against the outer wall of the plastic body 13. Above the ignition device, the housing 7 of the pressure element 12 forms a cavity in which a gas-generating charge 21 is arranged, which is protected on its lower side by a cover film 22. On the upper end face, the housing 7 has a predetermined breaking point 23 through which the released gas can leave the pressure element 12. The flange 18 already described above rests on an edge of the housing 7, a cone in a part 24 pressing the flange 18 and thus the ignition device sealingly against the housing 7. At the lower end of the ignition device, a known short-circuit socket 25 is shown, which short-circuits the two contact pins 3, 4 when the plug is not inserted. According to the lobe-shaped second circumferential extension 9 projects close to the housing 7 of the Pressure element 12 approach. In the case of electrostatic charges between a contact pin 3, 4 and the housing 7, a voltage flashover takes place in a zone which is far away from the ignition sets 5, 6 in the ignition device 1. This arrangement thus provides protection against electrostatic discharge.

Fig. 4 zeigt eine alternative Anzündeinrichtung. Die Alternative besteht darin, daß der Kunststoffkörper 13 im oberen Bereich des Aufnahmeteils 2 eine ringförmige Ausnehmung 26 aufweist. Hierdurch liegt das Aufnahmeteil 2 bzw. die Messinghülse, in der sich die Anzündsätze 5, 6 befinden, im oberen Bereich frei. Dies hat den Vorteil, daß beim Zünden der mechanische Impuls (Schockbelastung) nicht direkt in den Kunststoffkörper eingeleitet wird. Die Ausnehmung 26 erstreckt sich nahezu über die gesamte Länge des zweiten Anzündsatzes 6. Das untere Ende der Ausnehmung 26 ist mit einem Radius ausgebildet.4 shows an alternative ignition device. The alternative is that the plastic body 13 has an annular recess 26 in the upper region of the receiving part 2. As a result, the receiving part 2 or the brass sleeve, in which the igniter sets 5, 6 are located, is exposed in the upper region. This has the advantage that the mechanical impulse (shock load) is not introduced directly into the plastic body during ignition. The recess 26 extends almost over the entire length of the second ignition charge 6. The lower end of the recess 26 is formed with a radius.

Das in Fig. 4 beschriebene Druckelement zeigt weiterhin eine Ausführungsform ohne Anschlußbuchse. Hier erfolgt die Kontaktierung zwischen den Kontaktstiften 3, 4 und der Zuleitung mittels Lötverbindung bzw. Klemmverbindung.The pressure element described in Fig. 4 also shows an embodiment without a socket. Here, the contacting between the contact pins 3, 4 and the supply line takes place by means of a soldered connection or a clamp connection.

Die in den Figuren gezeigte Ringdichtung 20 dient auch als Schutz der gaserzeugenden Ladung 21 vor Feuchtigkeit.The ring seal 20 shown in the figures also serves to protect the gas-generating charge 21 from moisture.

Hochfeste Kunststoffe haben oftmals eine hohe Spannungsrißempfindlichkeit. Das Aufnahmeteil 2 setzt die durch das Einpressen der Anzündsätze entstehenden Spannungen im Kunststoffkörper herab. Hierdurch entstehen keine Langzeitrisse im Kunststoffkörper.High-strength plastics often have a high sensitivity to stress cracking. The receiving part 2 reduces the tensions in the plastic body caused by the pressing in of the ignition charges. This means that there are no long-term cracks in the plastic body.
