Abstract
Description
Die Erfindung betrifft einen elektrischer Miniaturschalter in einem geschlossenen Gehäuse mit einer Schaltvorrichtung.The The invention relates to a miniature electrical switch in one closed housing with a switching device.
Ein derartiger Schalter wird zur Auslösung elektrischer Schaltvorgänge benötigt, wobei aufgrund umweltrelevanter Einsatzbedingungen eine geschlossene Bauweise erforderlich ist.One Such switch is required to trigger electrical switching operations, wherein due to environmentally relevant conditions of use a closed construction is required.
Aus
der
Miniaturschalter in derartiger Bauart haben den Nachteil, dass deren betätigende Mechanik in das Gehäuseinnere hineinreicht und stets gewissen Umwelteinflüssen ausgesetzt ist, so dass deren Einsatz in schwierigen Situationen fraglich erscheint oder einen erhöhten Aufwand zur Abdichtung erforderlich macht.miniature switches in such a design have the disadvantage that their actuating Mechanics in the housing interior extends and is always exposed to certain environmental influences, so that their use in difficult situations seems questionable or an elevated one Effort for sealing required.
Der Erfindung liegt daher die Aufgabe zugrunde, einen gegen Umwelteinflüsse unempfindlichen Miniaturschalter zu entwickeln.Of the Invention is therefore based on the object insensitive to environmental influences To develop miniature switches.
Diese Aufgabe wird dadurch gelöst, dass die Schaltvorrichtung aus einem schwenkbar gelagerten Hebelarm mit einem daran angeordneten Schaltblech gebildet ist, dass in dem Gehäuse ein Reedrelais mittels eines Permanentmagneten in einem permanent wirkenden Magnetfeld gehalten wird, und dass bei Eintauchen des Schaltbleches in das Magnetfeld, das Reedrelais, einen elektrischen Schaltvorgang auslöst.These Task is solved by that the switching device consists of a pivotally mounted lever arm is formed with a switching plate arranged thereon that in the casing a reed relay by means of a permanent magnet in a permanent acting magnetic field is maintained, and that when immersing the Switch plates in the magnetic field, the reed relay, an electric Switching triggers.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2–5 angegeben.advantageous Embodiments of the invention are specified in claims 2-5.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass mit zumindest gleichen Abmessungen eines bekannten Miniaturschalters der erfindungsgemäße Schalter weitestgehend unabhängig von Umwelteinflüssen einsetzbar ist.The particular advantages of the invention are that with at least the same dimensions of a known miniature switch the switch according to the invention largely independent of environmental influences can be used.
Vorteilhaft ist der Einsatz eines komplett geschlossenen Gehäuses, in dem das Schaltglied sowie das für den Signaltransport erforderliche elektrische Kabel komplett umspritzt sind.Advantageous is the use of a completely enclosed housing in which the switching element as well as for The signal transport required electrical cable completely encapsulated are.
Lediglich eine erforderliche Mechanik in Form eines schwenkbaren Hebelarmes ist außerhalb des Gehäuses angeordnet.Only a required mechanism in the form of a pivoting lever arm is outside of housing arranged.
Das Schaltglied im Gehäuseinneren ist ein so genanntes Reedrelais, das mit dem elektrischen Kabel verbunden ist.The Switching element inside the housing is a so-called reed relay, with the electric cable connected is.
Zur Erzielung eines Schaltvorganges des Reedrelais ist ein an dem Hebelarm fixiertes Schaltblech vorgesehen, das in das durch einen Permanentmagneten aufrechtgehaltens Magnetfeld eindringt und bei Annäherung an das Reedrelais einen Schaltvorgang auslöst und eine auf einem zugeführten elektrischen Leiter vorhandene Signalspannung sperrt.to Achieving a switching operation of the reed relay is on the lever arm fixed switching plate provided in the by a permanent magnet maintained magnetic field penetrates and approaching the reed relay triggers a switching operation and one on a supplied electrical Conductor blocks existing signal voltage.
Bei einem Entfernen des ferromagnetischen Schaltbleches wird die Schaltspannung wieder durchgeschaltet.at a removal of the ferromagnetic switching plate is the switching voltage switched through again.
Dabei ist vorgesehen, den Hebelarm mittels einer Biegefeder zwangsweise auf Abstand zu dem Magnetfeld zwischen dem Permanentmagnet und dem Reedrelais zu halten, so dass ein Schaltvorgang nur unter Aufbringung einer Mindestkraft auf das freie Ende des Hebelarmes erfolgt.there is provided, the lever arm forcibly by means of a bending spring at a distance to the magnetic field between the permanent magnet and the Hold reed relay, allowing a switching operation only under application a minimum force is applied to the free end of the lever arm.
Ein Reedrelais ist ein elektrisches Bauteil zum Schalten eines Stromkreises, wobei die Schaltkontakte unter Vakuum oder Schutzgas in einem Glaskolben eingeschmolzen sind. Die Kontaktbetätigung erfolgt durch ein Magnetfeld, das von außen angelegt werden kann oder in einer eigenen Magnetspule elektrisch erzeugt wird.One Reed relay is an electrical component for switching a circuit, wherein the switch contacts under vacuum or inert gas in a glass flask are melted down. The contact operation is carried out by a magnetic field, that from the outside can be created or in a separate solenoid electrically is produced.
