Zündbrüekenträger für elektrische ZünderIgnition bridge carrier for electric igniters
Gegenstand der Erfindung ist ein Zündbrückenträger für elektrische Zünder, bei dem in einem metallischen Ring ein Isolierkörper mit mindestens einer Bohrung angeordnet ist, in der ein Kontaktstift als Stromzuleitung eingepaßt ist, der durch eine Zündbrücke mit dem Metallring elektrisch verbunden ist.The subject of the invention is an ignition bridge carrier for electrical detonators, in which an insulating body with at least one bore is arranged in a metallic ring, in which a contact pin is fitted as a power supply line, which is electrically connected to the metallic ring by an ignition bridge.
Zündbrüekenträger der genannten Art, die zum Anzünden von Anzündsätzen, Verzögerungssätzen, pyrotechnischen Mischungen sowie zur Zündung von Primärstoffen und -sätzen verwendet werden, sind aus der DE-A-31* 16 735 bekannt. Diese Zündbrüekenträger sind mechanisch and thermisch nur gering belastbar. Hier will die Erfindung Abhilfe schaffen.Ignition bridge carriers of the type mentioned, which are used for igniting ignition charges, delay charges, pyrotechnic mixtures and for igniting primary substances and charges, are known from DE-A-3 1 * 16 735. These ignition bridge carriers can only withstand low mechanical and thermal loads. The invention aims to remedy this.
Die Aufgabe wi"d dadurch gelöst, daß der Kontaktstift mit einem Wulst versehen ist, der die Lage des Kontaktstiftes in der Bohrung des Isolierkörpers festlegt.The task is solved by providing the contact pin with a bead that determines the position of the contact pin in the hole of the insulating body.
Bevorzugt sind im Isolierkörper zwei Bohrungen angeordnet, in denen Kontaktstifte als Stromzuleitungen eingepaßt sind, die durch eine Zündbrücke elektrisch leitend miteinander verbunden sind.Preferably, two bores are arranged in the insulating body, in which contact pins are fitted as power supply lines, which are electrically connected to one another by an ignition bridge.
DiS Isüllerkörpei bestehen bevorzugt aus Aluminiumoxidkeramik mit einem Al2O_-Gehalt > 90 %· Die Mantelfläche des Isolierkörners sowie die Wände seiner Bohrungen können metallisiert sein.The insulating bodies are preferably made of aluminium oxide ceramic with an Al 2 O_ content > 90 %. The outer surface of the insulating body and the walls of its bores can be metallised.
Der erfindungsgemäße Zündbrüekenträger bietet neben guten mechanischen und thermischen Eigenschaften vor allem Vorteile bei seiner Fertigung. Insbesondere läßt sich die Zündbrücke ohne Zwischenbearbeitung mittels Sputterverfahren auf den Isolierkörper aufbringen und mittels Lasertrimmverfahren auf den gewünschten Widerstandswert bringen. The ignition bridge carrier according to the invention offers not only good mechanical and thermal properties but also advantages in its manufacture. In particular, the ignition bridge can be applied to the insulating body without intermediate processing using a sputtering process and brought to the desired resistance value using a laser trimming process.

Der Zündbrüekenträger besteht aus einem metallischen Ring 1, in dem ein Isolierkörper 2 aus Keramik angeordnet ist. Der Isolierkörper 2 kann auf seiner Mantelfläche 6 metallisiert sein v.niöiio uärgeätellt/. Sr besitzt Sffsi Bohrungen, inThe ignition bridge carrier consists of a metallic ring 1, in which an insulating body 2 made of ceramic is arranged. The insulating body 2 can be metallized on its outer surface 6. It has 5 holes in denen elektrisch leitende Kontaktstifte 3 angeordnet sind. Die Kontaktstifte 3 sind mit Wülsten 7 versehen, um ihre Lage in den Bohrungen festzulegen. Metallring 1 und Isolierkörper 2 bzw. Isolierkörper 2 und Kontaktstifte 3on which electrically conductive contact pins 3 are arranged. The contact pins 3 are provided with beads 7 to determine their position in the holes. Metal ring 1 and insulating body 2 or insulating body 2 and contact pins 3 werden durch Hartlöten bei ca. 800 bis 9000C miteinander verbunden. Es bietet gewisse Vorteile, die Enden d^r Bohrungen mit Pasen 8 zu versehen. Es entstehen Lotmulden über eine Metallschicht 4, die durch Sputtern aufgebracht wird, sind die beiden Lotmulden und damit die Kontaktstifteare connected to each other by brazing at approx. 800 to 900 0 C. It offers certain advantages to provide the ends of the holes with slots 8. Solder troughs are created over a metal layer 4, which is applied by sputtering, the two solder troughs and thus the contact pins elektrisch leitend verbunden. Die eigentliche Zündbrücke 5 und damit der Widerstand zwischen den Kontaktstiften 3 kann mittels an sich bekannter Lasertrimmtechnik aus der Metallschicht 4 herausgearbeitet werden. Um geschlossene Metallschichten 4 zu gewährleisten, ist darauf zu achten,electrically connected. The actual ignition bridge 5 and thus the resistance between the contact pins 3 can be machined out of the metal layer 4 using known laser trimming technology. In order to ensure closed metal layers 4, care must be taken to daß die Oberflächenrauhigkeit Ra < 0,55 um beträgt.that the surface roughness Ra is < 0.55 µm.
