Abstract
Trennelement zum lösbaren Verbinden von zwei Bauteilen (7, 9) mit einer Zündeinrichtung zum Zünden einer Treibladung, welche durch Deflagration die Trennung des Trennelements einleitet, mit einer zwischen den zu lösenden Bauteilen (7, 9) des Trennelements (5) angeordneten mechanischen Sperrvorrichtung, welche über einen Kolben (23) entriegelbar ist, wobei der Kolben durch den bei der Deflagration entstehenden Gasdruck in die Freigabestellung bewegt wird, wobei die Sperrvorrichtung durch mindestens zwei Kugeln (17) gebildet ist, welche durch Formschluss die lösbaren Bauteile (7, 9) des Trennelements (5) über den Kolben (23) direkt oder indirekt verbinden, wobei das erste (7) und das zweite Bauteil (9) des Trennelements (5) zur Aufnahme des Kolbens (23) miteinander fluchtende Aussparungen aufweisen und in der Sperrfunktion die Kugeln (17) in je eine Ausnehmung in dem ersten (7) und dem zweiten Bauteil (9) des Trennelements (5) eingreifen, wobei bei Verschiebung des Kolbens (23) in die Freigabestellung die Kugeln (17) so bewegt werden, dass die Sperrung zwischen den jeweiligen Bauteilen (7, 9) und dem Kolben (23) oder einem mit diesem in Wirkverbindung stehenden Sperrelement (59, 61) aufgehoben wird, so dass eine weitere Bewegung des Kolbens (23) bis in eine Stellung möglich ist, in der er oder das mit ihm in Wirkverbindung stehende Sperrelement (59, 61) nicht mehr in die Trennebene (T) zwischen dem ersten (7) und dem zweiten Bauteil (9) des Trennelements (5) hineinragt, nach Patentanmeldung DE 10 2004 062 079 B4 dadurch gekennzeichnet, dass eine Zündleitung (33) vorgesehen ist, welche die in dem Schaft (5) des als Schraube ausgeführten Trennelements angeordnete Treibladung (25) mit einem elektrischen Kontaktteil (35) am Kopf (1) der Schraube verbindet.Separating element for the detachable connection of two components (7, 9) with an ignition device for igniting a propellant charge, which initiates the separation of the separating element by deflagration, with a mechanical locking device arranged between the components (7, 9) of the separating element (5) to be detached, which can be unlocked via a piston (23), the piston being moved into the release position by the gas pressure generated during deflagration, the locking device being formed by at least two balls (17) which form the detachable components (7, 9) of the separating element (5) directly or indirectly via the piston (23), the first (7) and the second component (9) of the separating element (5) for receiving the piston (23) having recesses aligned with one another and in the blocking function the Balls (17) each engage in a recess in the first (7) and the second component (9) of the separating element (5), whereby when the piston (23) is moved into the Fr input position the balls (17) are moved in such a way that the lock between the respective components (7, 9) and the piston (23) or a locking element (59, 61) that is in operative connection therewith is canceled, so that further movement of the Piston (23) is possible up to a position in which it or the locking element (59, 61) which is in operative connection with it no longer enters the parting plane (T) between the first (7) and the second component (9) of the separating element (5) protrudes, according to patent application DE 10 2004 062 079 B4, characterized in that an ignition line (33) is provided which connects the propellant charge (25) arranged in the shaft (5) of the separating element designed as a screw with an electrical contact part (35). connects to the head (1) of the screw.
Description
Die Erfindung bezieht sich auf eine Trennschraube zum lösbaren Verbinden von zwei Bauteilen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a separating screw for releasably connecting two components according to the preamble of
Die nicht vorveröffentlichte Patentanmeldung
Ein besonderes Merkmal des Trennelements gemäß der Patentanmeldung
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Trennelement gemäß der Patentanmeldung
Die Aufgabe wird dadurch gelöst, dass eine Zündleitung vorgesehen ist, welche die in den Schaft des als Schraube ausgeführten Trennelementes angeordnete Treibladung mit einem elektrischen Kontaktteil am Kopf der Schraube verbindet. Diese Anordnung stellt sicher, dass trotz einer im Schaft der Trennschraube angeordneten Treibladung diese über Kontakte am Schraubenkopf gezündet werden kann. Es ist also möglich, die Trennschraube wie eine herkömmliche Schraube einzuschrauben und erst dann den elektrischen Kontakt herzustellen. Die erfindungsgemäße Trennschraube kann deshalb auch an Stellen Verwendung finden, an denen das Schraubende nicht oder nur sehr schwer zugänglich ist. Wenn die elektrischen Anschlüsse zu einem späteren Zeitpunkt erfolgen können, wird die Sicherheit gegen unbeabsichtigtes Auslösen außerdem erhöht.The object is achieved in that an ignition line is provided which connects the propellant charge arranged in the shaft of the separating element designed as a screw to an electrical contact part on the head of the screw. This arrangement ensures that despite a propellant charge arranged in the shaft of the separating screw, it can be ignited via contacts on the screw head. It is therefore possible to screw in the separating screw like a conventional screw and only then make the electrical contact. The separating screw according to the invention can therefore also be used in places where the screw end is not accessible or only with great difficulty. If the electrical connections can be made at a later point in time, the security against unintentional triggering is also increased.
Vorteilhaft wird die Zündleitung mittig durch das Trennelement hindurchgeführt. So kann bspw. in einfacher Weise durch zentrische Bohrungen in den betroffenen Bauteilen die Voraussetzung zur Hindurchführung der Zündleitung geschaffen werden. Es ist unbeachtlich,, wenn bei Auslösung des Trennelements die Zündleitung zerstört wird.The ignition line is advantageously passed centrally through the separating element. Thus, for example, the prerequisites for passing the ignition cable through can be created in a simple manner by means of central bores in the components concerned. It is irrelevant if the ignition cable is destroyed when the isolating element is triggered.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.
