Description

Elektrischer Zünder Bei verschiedenen vorgekommenen Grubenkatastrophen wurde als wahrscheinliche Ursache der Schlagwetterentzündung die leichte Entflammbarkeit der bisher bei der Fabrikation elektrischer Zünder gebräuchlichen Schwefelvergußmasse festgestellt, mittels welcher der Zündkörper oder die Zündpille in der Zünderhülse oder der Sprengkapsel befestigt wird.Electric detonator During various mine disasters The likely cause of firedamp ignition was found to be its easy flammability the sulfur potting compound previously used in the manufacture of electric detonators determined by means of which the detonator or the detonator in the detonator sleeve or the detonator is attached.

Man hat daher vorgeschlagen, anstatt der vorgenannten Schwefelvergußmasse unverbrennbare Materialien zur Befestigung des Zündkörpers zu verwenden. Als solche Materialien für die Vergußmasse kommen vornehmlich Metalle oder Metallegierungen in Betracht. Um dabei solche von verhältnismäßig hohem Schmelzpunkt, wie beispielsweise Blei- und Zinn, zu benutzen, wird erfindungsgemäß, zum Schutze des Zündkörpers vor zu hoher Temperatur eine besondere Schutzhülse oder ein Mantel aus geeignetem Material, wie gegebenenfalls Glas, Por: zellan o. dgl., in Anwendung gebracht.It has therefore been proposed instead of the aforementioned sulfur potting compound to use incombustible materials to fix the detonator. As such Materials for the potting compound are primarily metals or metal alloys into consideration. In order to do so, such as those of a relatively high melting point According to the invention, lead and tin are to be used to protect the detonator too high a temperature a special protective sleeve or a jacket made of suitable material, such as, if appropriate, glass, porcelain or the like, brought into use.

Auf der Zeichnung ist ein gemäß vorliegender Erfindung hergestellter Zünder in einem Ausführungsbeispiel im Längsschnitt dargestellt. , In die aus Messing oder Pappe bestehende Hülse a wird in üblicher Weise die Zündpille oder der Zündkörper beingesetzt, an dessen mit Folie belegten Pappstreifen e die Zuleitung f angelötet ist. Der Zündkörper ist von einer Hülse oder einem Mantel k aus geeignetem Material, vorzugsweise aus Glas, Porzellan u. dgl. unverbrennbaren Stoffen von schlechter Wärmeleitfähigkeit, umgeben. Der überstehende Raum zwischen der Hülse a und den Leitungsdrähten ist alsdann mit einer Vergußmasse ausgefüllt, zu welcher vorteilhafterwei.se Metalle und Metallegierungen verwendet werden, die- sich beispielsweise in verschiedenen Mengenverhältnissen aus Blei, Zinn und Wismut zusammensetzen lassen.In the drawing is a manufactured according to the present invention Detonator shown in one embodiment in longitudinal section. , In the brass or cardboard existing sleeve a is in the usual way the squib or the detonator set, on whose cardboard strip e covered with foil the supply line f is soldered is. The ignition body is made of a sleeve or a jacket k made of a suitable material, preferably made of glass, porcelain and similar non-combustible materials of poor quality Thermal conductivity, surrounded. The protruding space between the sleeve a and the Line wires is then filled with a potting compound, which is advantageous Metals and metal alloys are used, for example in different Let the proportions of lead, tin and bismuth be put together.

Auch läßt sich der meiner Umhüllung von Glas, Porzellan usw. befindliche Zündkörper mittels unverbrennlicher Lacke o..dgl. in die Zünderhülse einkleben und befestigen.The one in my case of glass, porcelain, etc. can also be used Ignition body using incombustible paints or the like. Glue into the detonator sleeve and attach.

Zünder, die in vorgenannter Weise hergestellt sind, bieten die Sicherheit, daß, bei der Explosion der Sprengkapsel die Vergußmasse sich nicht entzündet und durch Umherspritzen derselben etwaige Schlagwetteransammlungen zur Entzündung bringen kann.Detonators, which are manufactured in the aforementioned manner, offer the security, that, when the detonator explodes, the potting compound does not ignite and by splashing them around, cause any accumulations of firedamp to ignite can.
