Description
In der elektrischen Schaltungstechnik besteht oft der Wunsch, für das Schließen der dort benötigten Steuerstromkreise Schalteinrichtungen mit Kontakten zur Verfügung zu haben, welche in ihrer Funktion im Laufe der Zeit durch äußere Einflüsse nicht nachteilig beeinflußt werden, welche weiterhin schnell und bei recht genau definierter Feldstärke ihres Elektromagneten betätigt werden. Hier haben sich die in einem Magnetfeld beeinflußbaren Kontakte, die sogenannten Reed-Kontakte, als besonders brauchbar erwiesen. Durch den luftdichten Abschluß in einer Glasrohre mit Schutzgas werden sie nicht durch Staub oder aggressive Gase in ihrer Funktion gestört, so daß sie ohne Wartung auch nach langen Betriebspausen zuverlässig arbeiten. Infolge ihrer kleinen bewegten Masse erfolgt die Kontaktgabe schnell, und zwar bei einer recht genau definierten Feldstärke ihrer Magnetspule.In electrical circuit technology there is often the Wish, for the closing of the control circuits required there switching devices with contacts for To have available which are not detrimental in their function over time due to external influences are influenced, which continue to be fast and with a very precisely defined field strength of their electromagnet be operated. The contacts that can be influenced in a magnetic field, the so-called Reed contacts, proved to be particularly useful. Through the airtight seal in a glass tube with They are not disturbed in their function by dust or aggressive gases, so that they are without protective gas Maintenance work reliably even after long breaks in operation. As a result of their small moving mass takes place making contact quickly, with a very precisely defined field strength of your magnet coil.
Die Erfindung beschäftigt sich mit der Aufgabe, die Betätigung solcher Kontakte von einem jeweils gewünschten Ansprechwert strom- oder spannungsabhängig zu machen. Hierzu werden gemäß der Erfindung die zur Betätigung des Kontaktes erforderliche Magnetspule oder der Kontakt selbst mit Mitteln ausgerüstet, durch deren Einstellung der Neigungswinkel der im Innern der Magnetspule untergebrachten Kontaktanordnung zur Richtung des Kraftlinienfeldes der Magnetspule zwecks Einstellbarkeit des Ansprechwertes der Magnetspule veränderbar ist.The invention is concerned with the task of actuating such contacts from a respectively desired To make the response value dependent on the current or voltage. To this end, according to the invention the magnetic coil required to actuate the contact or the contact itself with means equipped, by adjusting the angle of inclination of those housed inside the solenoid Contact arrangement for the direction of the force line field of the magnet coil for the purpose of adjusting the response value the solenoid is changeable.
Dieser Lösungsgedanke beruht auf der Erkenntnis, daß durch Änderung dieser Richtung der Kontaktanordnung zur Richtung des Kraftlinienfeldes der Magnetspule eine einstellbare strom- oder spannungsabhängige Kontaktbetätigung erzielbar ist.This solution idea is based on the knowledge that by changing this direction of the contact arrangement for the direction of the force line field of the solenoid an adjustable current- or voltage-dependent Contact actuation is achievable.
Bei bekannten Anordnungen wird zur Änderung des Ansprechwertes entweder eine Magnetspule mit mehreren Anzapfungen verwendet, oder der Luftspalt zwischen Anker und Spulenkern ist durch Verschiebung des Ankers gegenüber dem Spulenkern veränderbar, oder es ist ein einstellbarer Nebenschlußweg vorhanden.In known arrangements, either a magnetic coil is used to change the response value multiple taps are used, or the air gap between armature and coil core is due to displacement of the armature can be changed in relation to the coil core, or it is an adjustable shunt path available.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Die Magnetspule 1, die zur Betätigung des Kontaktes 2 erforderlich ist, oder der Kontakt 2 selbst ist mit Mitteln ausgerüstet, durch deren Ein-Schalteinrichtung An exemplary embodiment is shown in the drawing. The solenoid 1, which is used to actuate the Contact 2 is required, or the contact 2 itself is equipped with means by means of their on-switching device

stellung der Neigungswinkel der im Innern der Magnetspule untergebrachten Kontaktanordnung zur Richtung des Kraftlinienfeldes der Magnetspule veränderbar ist. Damit läßt sich die Ansprechfeldstärke der Magnetspule auf den jeweils gewünschten Wert einstellen, und zwar ist ein um so kleinerer Ansprechstrom erforderlich, je weiter z.B. der Kontakt2 zu seiner horizontalen Lage hin verstellt wird.position of the angle of inclination of the contact arrangement housed inside the magnet coil Direction of the force line field of the solenoid coil can be changed. This allows the response field strength set the solenoid to the desired value, the lower the response current required, the further e.g. Contact 2 is moved towards its horizontal position.
