Description
Die Erfindung betrifft eine Zündvorrichtung für pyrotechnische Gasgeneratoren.The The invention relates to an ignition device for pyrotechnic Inflators.
Eine
Zündvorrichtung
ist der
Der Boden wird von mindestens zwei Elektroden zur Kontaktierung des Schaltkreises durchquert, wobei in einem Ausführungsbeispiel eine der Elektroden gegen den Boden isoliert ist, die andere jedoch einen Kontakt aufweist. Diese Elektrode wirkt offensichtlich als Substratkontakt für den darauf angeordneten Halbleiterschaltkreis.Of the Soil is used by at least two electrodes for contacting the Crosses circuit, wherein in one embodiment, one of the electrodes is insulated against the ground, the other has a contact. This electrode obviously acts as a substrate contact for it arranged semiconductor circuit.
Die Herstellung dieser Zündvorrichtung erweist sich jedoch als recht aufwendig, insbesondere aufgrund der erforderlichen Kontaktierung zwischen Boden und Elektrode und der Zusammenfügung der verschiedenen Gehäuseteile.The Production of this ignition device However, proves to be quite expensive, especially due to the required contact between ground and electrode and the joining the different housing parts.
Aus
der
Aufgabe der Erfindung ist es, eine Zündvorrichtung mit vergleichbar guter Abschirmung vorzustellen, welche einfacher herstellbar ist. Diese Aufgabe wird durch Anspruch 1 gelöst.task The invention is an ignition device with comparably good shielding, which is easier can be produced. This object is solved by claim 1.
So ist eine auf die Zündvorrichtung aufschiebbare metallische Kappe vorgesehen, welche die Zündvorrichtung zumindest im Bereich der Anschlussstifte umfasst. Diese Kappe ist durch Aufschieben auf die Zündvorrichtung äußerst einfach und auch nach dem Umspritzen der Zündvorrichtung mit einem Gehäusekunststoff montierbar. Die Kappe weist Öffnungen zum Durchführen der Anschlussstifte auf.So is one on the ignition device slidable metallic cap provided which the ignition device at least in the area of the pins. This cap is by sliding on the ignition extremely simple and even after the encapsulation of the ignition device with a housing plastic mountable. The cap has openings to perform the pins on.
An der Öffnung für den mit dem Massepotential zu verbindenden Anschlussstift sind Mittel vorgesehen, welche die Kappe elektrisch mit diesem Anschlussstift verbinden, so dass eine Erdung der Kappe über den Anschlussstift erreicht wird.At the opening for the to be connected to the ground potential pin are means provided the cap electrically with this pin connect, so that a grounding of the cap reaches over the pin becomes.
Besonders einfach kann dieser elektrische Kontakt zwischen der Kappe und dem Anschlußstift durch einen einstückig aus der metallischen Kappe ausgeformten Spreizklemmkontakt realisiert werden, der beim Aufschieben der Kappe über die Anschlussstifte auf die Zündvorrichtung durch den Anschlussstift aufgespreizt wird und zu einer Klemmkontaktierung führt. Eine solche Kappe lässt sich äußerst einfach herstellen und montieren. Die Verbindung ist elektrisch wie auch mechanisch äußerst zuverlässig. Außerdem kann die Kappe bspw. durch eine Presspassung mit dem Gehäuse der Zündvorrichtung zusätzlich fixiert werden.Especially simply this electrical contact between the cap and the Pin through one piece realized from the metallic cap formed Spreizklemmkontakt when pushing the cap over the pins on the ignition device is spread by the pin and a Klemmkontaktierung leads. Such a cap leaves extremely simple manufacture and assemble. The connection is electric as well mechanically extremely reliable. In addition, can the cap bspw. By an interference fit with the housing of detonator additionally be fixed.
Zudem kann die Kappe auch mit anderen metallischen Gehäuseteilen des Gasgenerators oder bei Anwendung im Kraftfahrzeug mit Karosserieteilen verbunden sein.moreover The cap can also be used with other metallic body parts of the gas generator or when used in the motor vehicle with body parts connected be.
Die Erfindung soll nachfolgend anhand von Ausführungsbeispielen und Figuren näher erläutert werden. Kurze Beschreibung der Figuren:The Invention will be described below with reference to embodiments and figures be explained in more detail. Brief description of the figures:
