Abstract
Description
Die Erfindung betrifft einen pyroelektrischen Anzünder mit einer Kapsel in der ein Glaseinsatz eingebracht ist und zumindest ein elektrisch leitender Stift den Glaseinsatz durchragt und zumindest der eine Stift auf der Wirkseite des Anzünders mit einem Zündbrückenträger verbunden ist und sich auf dem Zündbrückenträger eine pyrotechnische Anzündladung befindet.The invention relates to a pyroelectric lighter a capsule in which a glass insert is inserted and at least an electrically conductive pin protrudes through the glass insert and at least one of the pins on the active side of the lighter is connected to an ignition bridge carrier and there is one on the ignition bridge support pyrotechnic charge located.
Erfindungsgemäß wird vorgeschlagen, dass in der Kapsel oberhalb des Glaseinsatzes ein Bauraum zur Aufnahme des Zündbrückenträgers und der pyrotechnischen Anzündladung angeordnet ist.According to the invention it is proposed that in the capsule above the glass insert a space to accommodate the Fuse holder and the pyrotechnic ignition charge is arranged.
Die erfindungsgemäße Glasdurchführung hat in pyrotechnischen Anzündern folgende Funktionen: mechanische Fixierung der elektrischen Komponente Zündbrückenträger einschließlich Sicherstellung der elektrischen Kontaktierung nach außen, Aufnahme einer pyrotechnischen Anzündladung und – in Verbindung mit einer vorzugsweise metallischen Hülse – Sicherstellung, dass der Anzünder dicht gegen Umwelteinflüsse ist, auch nach jahrelanger Einsatzdauer.The glass bushing according to the invention has in pyrotechnic igniters following functions: mechanical fixation of the electrical component Ignition bridge bracket including securing electrical contact to the outside, inclusion of a pyrotechnic ignition charge and in Connection with a preferably metallic sleeve - Ensure that the lighter tight against environmental influences is, even after years of use.
Erfindungsgemäß können obige Forderungen kostengünstig dadurch gelöst werden, dass für die Glasdurchführung preiswerte Materialien mit geringem Fertigungsaufwand eingesetzt werden und durch die konstruktive Formgebung notwendige Systemforderungen integriert werden.According to the invention, the above requirements can be achieved inexpensively solved be that for the Glass bushing inexpensive materials with low manufacturing costs become necessary and due to the constructive design necessary system requirements to get integrated.
In bevorzugter Ausgestaltung weist der zumindest eine Stift in Höhe des Glaseinsatzes eine Abflachung und/oder Aufweitung auf.In a preferred embodiment the at least one pin in height flattening and / or widening of the glass insert.
Bei zwei Stiften die den Glaseinsatz durchragen, weist vorteilhaft in Höhe des Glaseinsatzes ein Stift eine Abflachung und der andere Stift eine um 180 ° versetzte Aufweitung auf.With two pens the glass insert protrude, advantageously has a pin at the level of the glass insert one flat and the other pin one offset by 180 ° Widening up.
In bevorzugter Ausführungsform weist die Innenseite der Kapsel in Höhe des Glaseinsatzes eine Aufrauhung z. B. durch Rillen auf und der Glaseinsatz ragt in diese Aufrauhung hinein.In a preferred embodiment the inside of the capsule is roughened at the level of the glass insert z. B. by grooves and the glass insert protrudes into this roughening into it.
Um die Kapsel preiswert und dennoch stabil herstellen zu können, ist die Kapsel durch eine Umform- und/oder Stanzoperation aus einem Edelstahl oder Stahl mit oder ohne Oberflächenschutz gefertigt.To the capsule inexpensive and yet to be able to manufacture stably, is the capsule made by a forming and / or punching operation Stainless steel or steel with or without surface protection.
Der Anzünder weist vorteilhaft ein napfartiges Gehäuse auf, welches die Kapsel auf der Wirkseite umgreift. Erfindungsgemäß ist die Kapsel mit dem Gehäuse über eine Verschweißung oder eine Laserschweißung dicht verbunden. Innerhalb des Gehäuses befindet sich z. B. eine Treibladung.The lighter advantageously has a Cup-like housing which encompasses the capsule on the active side. According to the invention Capsule with the housing over a welding or laser welding tightly connected. There is e.g. Legs Propellant charge.
Wenn zwei Stifte den Glaseinsatz durchragen, ist bevorzugt ein Stift mit der Kapsel elektrisch leitend verbunden. Hierzu kann der zu verbindende Stift einen Bund aufweisen, der z. B. durch eine Lötung mit der Kapsel elektrisch verbunden ist.If two pins the glass insert protrude, a pin with the capsule is preferably electrically conductive connected. For this purpose, the pin to be connected can have a collar, the z. B. by soldering is electrically connected to the capsule.
Nachfolgend wird die Erfindung an Hand von Figuren näher erläutert.The invention is as follows Hand of figures closer explained.
In
Die Wirkungsweise der „Glasdurchführung" beruht darauf, dass
die eingesetzten Materialien betreff ihres Ausdehnungskoeffizienten
in der Art und Weise abgestimmt sind, dass nach dem Einbringen der
Glasschmelze im erhitzten Zustand beim Erkalten ein Druckverbund
erzeugt wird, der eine dichte Verbindung zwischen Kapsel
