Die Steuerschaltung eines Projektils ist kurz vor dem Abschuß mit ihrer Stromversorgung zu verbinden. Nach dem Stand der Technik werden hierfür steckbare Brücken verwendet.The control circuit of a projectile is just before To connect launch to their power supply. After this Plug-in bridges are state of the art for this used.
Aufgabe der Erfindung ist es, eine Schalteinrichtung der eingangs genannten Art vorzuschlagen, die auch bei Beschleunigungen der Schalteinrichtung prellfrei ist und den Schaltzustand einfach erkennen läßt.The object of the invention is to provide a switching device to propose the type mentioned above, which also at Accelerations of the switching device is bounce-free and can easily recognize the switching state.
Erfindungsgemäß ist obige Aufgabe dadurch gelöst, daß der Leiterplatte ein Gewinde und für das Gewinde ein Schraubteil zugeordnet ist und daß bei am Gewinde festgeschraubtem Schraubteil dieses auf die Leiterbahnenden drückt, wodurch die Leiterbahnenden elektrisch verbunden sind.According to the invention, the above object is achieved in that the PCB one thread and one for the thread Screw part is assigned and that at the thread screwed this part onto the Track ends presses, causing the track ends are electrically connected.
Solange die elektrische Verbindung noch nicht hergestellt ist, ist dies am Fehlen des Schraubteils klar erkennbar. Ist das Schraubteil an der Leiterplatte festgeschraubt, dann verbindet dieses die Leiterbahnenden elektrisch. Die Verbindung ist beschleunigungsfest und prellfrei, so daß während des Abschusses und des Fluges des Projektils eine sichere und auch einfache Verbindung zwischen der Stromversorgung und der Steuerschaltung besteht. As long as the electrical connection has not yet been established is clearly recognizable by the absence of the screw part. If the screw part is screwed onto the circuit board, then this connects the conductor track ends electrically. The Connection is acceleration-resistant and bounce-free, so that during the launch and flight of the projectile secure and easy connection between the Power supply and the control circuit exists.
In bevorzugter Weiterbildung der Erfindung ist das Gewinde ein Muttergewinde und das Schraubteil ist eine Schraube, wobei der Schraubenkopf bei festgezogener Schraube die Leiterbahnenden kontaktiert.In a preferred development of the invention, this is Thread a nut thread and the screw part is one Screw, the screw head being tightened Screw contacts the conductor ends.
In weiterer Ausgestaltung der Erfindung ist das Muttergewinde von einer Schraubenmutter gebildet, die an der den Leiterbahnenden abgewandten Seite der Leiterplatte befestigt ist. Es ist jedoch auch möglich, die Schraubenmutter nicht von vornherein an der Leiterplatte festzulegen. Vorzugsweise werden dann die Schraubenmutter und der Schraubenkopf so ausgelegt, daß die gewünschte Verbindung unabhängig davon geschaffen wird, ob beim Anziehen der Schraube der Schraubenkopf oder die Schraubenmutter den Leiterbahnenden zugewandt ist.In a further embodiment of the invention Nut thread formed by a nut that attached to the side of the conductor facing away from the conductor ends PCB is attached. However, it is also possible not the screw nut from the start on the Determine circuit board. Then preferably Screw nut and the screw head designed so that the desired connection created regardless is whether the screw head when tightening the screw or the screw nut facing the conductor ends is.
In anderer Ausgestaltung der Erfindung kann das Muttergewinde auch direkt in der Leiterplatte ausgebildet sein, wenn diese eine hinreichende Stärke aufweist.In another embodiment of the invention, this can Mother thread also formed directly in the circuit board be if this is of sufficient strength.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen und der folgenden Beschreibung eines Ausführungsbeispiels. In der Zeichnung zeigtFurther advantageous embodiments of the invention result from the subclaims and the following Description of an embodiment. In the drawing shows
Fig. 1 eine Schalteinrichtung in Seitenansicht und Fig. 1 is a switching device in side view and
Fig. 2 eine Aufsicht längs der Linie II-II nach Fig. 1. Fig. 2 shows a plan along the line II-II of FIG. 1.
Auf einer kupferkaschierten Leiterplatte (1) sind zwei Leiterbahnenden (2, 3) ausgebildet. Diese sind mit einer Zinnschicht (4) versehen.Two conductor track ends ( 2, 3 ) are formed on a copper-clad printed circuit board ( 1 ). These are provided with a layer of tin ( 4 ).
Die Leiterplatte (1) weist mittig zwischen den Leiterbahnenden (2, 3) eine Bohrung (5) auf. Die Leiterbahnenden (2, 3) erstrecken sich konzentrisch zur Bohrung (5) auf Teilkreisen (vgl. Fig. 2).The circuit board ( 1 ) has a hole ( 5 ) centrally between the conductor track ends ( 2, 3 ). The conductor track ends ( 2, 3 ) extend concentrically to the bore ( 5 ) on partial circles (cf. FIG. 2).
An die den Leiterbahnenden (2, 3) abgewandte Seite der Leiterplatte (1) ist eine Mutter (6) angeklebt. Deren Gewinde liegt unterhalb der Bohrung (5).A nut ( 6 ) is glued to the side of the circuit board ( 1 ) facing away from the conductor track ends ( 2, 3 ). Their thread is below the hole ( 5 ).
In die Mutter (6) ist eine Schraube (7) einzuschrauben, deren Kopf (8) einen Durchmesser aufweist, der wenigstens ebenso groß ist wie der Kreis, auf dem die Leiterbahnenden (2) liegen.A screw ( 7 ) is screwed into the nut ( 6 ), the head ( 8 ) of which has a diameter which is at least as large as the circle on which the conductor track ends ( 2 ) lie.
Solange die Schraube (7) nicht eingeschraubt ist, ist dies deutlich zu erkennen. Die Leiterbahnenden (2, 3) sind als unverbunden sichtbar.As long as the screw ( 7 ) is not screwed in, this can be clearly seen. The conductor track ends ( 2, 3 ) are visible as unconnected.
Zur Verbindung der Leiterbahnenden (2, 3) wird die Schraube (7) in die Mutter (6) geschraubt. In Fig. 1 ist eine Schraubstellung gezeigt, in der die Schraube (7) noch nicht festgezogen ist. Wird die Schraube (7) festgezogen, dann preßt sich der Schraubenkopf (8) so auf die Zinnschicht (4), daß sie sich dem Schraubenkopf (8) anpaßt. Dadurch sind die beiden Leiterbahnenden (2) elektrisch verbunden, so daß eine Stromversorgung, die an das eine Leiterbahnende angeschlossen ist und eine Steuerschaltung, die an das andere Leiterbahnende angeschlossen ist, jetzt miteinander verbunden sind. Diese sichere elektrische Verbindung ist mechanisch fest. Sie kann sich auch bei hohen Beschleunigungen nicht lösen. Sie kann auch nicht zu Prellerscheinungen führen.To connect the conductor ends ( 2, 3 ), the screw ( 7 ) is screwed into the nut ( 6 ). In Fig. 1 a screw position is shown in which the screw ( 7 ) has not yet been tightened. If the screw ( 7 ) is tightened, the screw head ( 8 ) presses onto the tin layer ( 4 ) in such a way that it adapts to the screw head ( 8 ). As a result, the two conductor track ends ( 2 ) are electrically connected, so that a power supply which is connected to one conductor track end and a control circuit which is connected to the other conductor track end are now connected to one another. This secure electrical connection is mechanically firm. It cannot come loose even at high accelerations. It also cannot cause bruises.
Zusätzlich kann die Leiterplatte (1) in dem Projektil so angeordnet werden, daß die Längsachse der Schraube (7) senkrecht zur Beschleunigungsrichtung steht. Die Beschleunigung wirkt dann nicht in Schraubrichtung der Schraubverbindung, sondern quer hierzu.In addition, the circuit board ( 1 ) can be arranged in the projectile so that the longitudinal axis of the screw ( 7 ) is perpendicular to the direction of acceleration. The acceleration then does not act in the screwing direction of the screw connection, but across it.
In Sonderfällen ist es erwünscht, die mit der Schraube (7) geschaffene elektrische Verbindung wieder aufzutrennen. In special cases, it is desirable to disconnect the electrical connection created with the screw ( 7 ).
Dies ist einfach dadurch möglich, daß die Schraube (7) aus der Mutter (6) herausgeschraubt wird.This is possible simply by unscrewing the screw ( 7 ) from the nut ( 6 ).
Vorteilhaft ist bei der beschriebenen Schalteinrichtung auch, daß die Schraube (7) und die Mutter (6) handelsübliche Bauteile sind.It is also advantageous in the switching device described that the screw ( 7 ) and the nut ( 6 ) are commercially available components.
Bei der beschriebenen Einrichtung ist es auch möglich, mehr als zwei Leiterbahnenden zu verbinden. Es werden hierzu auf der Leiterplatte (1) anstelle der zwei Leiterbahnenden (2, 3) entsprechend mehrere Leiterbahnenden vorgesehen.With the device described, it is also possible to connect more than two conductor track ends. For this purpose , several conductor track ends are provided on the circuit board ( 1 ) instead of the two conductor track ends ( 2, 3 ).
