Stand der TechnikState of the art
Die Erfindung geht aus von einem magnetischen Positionssensor nach der Gattung des Hauptanspruchs.The The invention is based on a magnetic position sensor according to the Genus of the main claim.
Es
ist schon ein magnetischer Positionssensor aus der
Vorteile der ErfindungAdvantages of the invention
Der erfindungsgemäße magnetische Positionssensor mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass das Kontaktmittel keinen Anschluss an die Spannungsquelle benötigt, da es lediglich als elektrisch kurzschließende Überbrückung wirkt. Auf diese Weise werden die Herstellungskosten des Positionssensors verringert. Erfindungsgemäß wird dies erreicht, indem zusätzlich eine Leiterbahn auf dem Träger vorgesehen ist, die entlang den Leiterabschnitten der Widerstandsbahn verläuft, und dass die Biegeelemente des Kontaktmittels derart ausgebildet sind, dass sie die Leiterbahn bei ihrer Auslenkung mit zumindest einem der Leiterabschnitte der Widerstandsbahn elektrisch verbinden.Of the Magnetic position sensor according to the invention the characterizing features of the main claim has in contrast the advantage that the contact means no connection to the voltage source needed, as it is only as an electrically short-circuiting bridging acts. In this way, the manufacturing cost of the position sensor reduced. According to the invention this is achieved in addition, a trace on the carrier is provided along the conductor portions of the resistance path runs, and that the bending elements of the contact means are formed such that they the conductor track in its deflection with at least one of the conductor portions of the resistance path electrically connect.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen magnetischen Positionssensors möglich.By the measures listed in the dependent claims are advantageous developments and improvements of the main claim specified magnetic position sensor possible.
Besonders vorteilhaft ist, wenn die Biegeelemente des Kontaktmittels jeweils beidseitig gelagert sind und unter Einwirkung der Magneteinrichtung zwischen ihren Enden eine Biegung erfahren. Durch die beidseitige Lagerung der Biegeelemente wird eine bessere Rückfederung des Biegeelementes erreicht, die auch nach langer Betriebsdauer noch zuverlässig gewährleistet werden kann. Außerdem können durch die beidseitige Lagerung zwei elektrische Kontakte erreicht werden, nämlich einer mit dem Leiterabschnitt und ein weiterer mit der Leiterbahn.Especially is advantageous if the bending elements of the contact means respectively are mounted on both sides and under the action of the magnetic device between their ends undergo a bend. Due to the two-sided storage the bending elements is a better springback of the bending element achieved, even after a long service life still reliable can be guaranteed. In addition, you can achieved by the two-sided storage two electrical contacts be, namely one with the conductor section and another with the conductor track.
Gemäß einer vorteilhaften Ausführung verlaufen die Biegeelemente des Kontaktmittels im wesentlichen parallel zueinander.According to one Advantageous embodiment, the bending elements of the Contact means substantially parallel to each other.
Weiterhin vorteilhaft ist, wenn das Kontaktmittel zwei Befestigungsabschnitte aufweist, die über die Biegeelemente miteinander verbunden sind, da auf diese Weise eine Biegebalkenstruktur entsteht, deren Biegeelemente bei Einwirkung einer Magneteinrichtung als elektrische Überbrückung wirken und dabei eine elektrische Verbindung zwischen der Leiterbahn und zumindest einem der Leiterabschnitte der Widerstandsbahn schaffen.Farther is advantageous if the contact means two mounting portions has, which connected to each other via the bending elements are, because in this way a bending beam structure is created whose Bending elements when exposed to a magnetic device as an electrical bridge act while maintaining an electrical connection between the conductor track and create at least one of the conductor sections of the resistance path.
Sehr vorteilhaft ist es, wenn das Kontaktmittel im Abstand zur Widerstandsbahn bzw. zu den Leiterabschnitten am Träger befestigt ist, da auf diese Weise nur bei Einwirkung der Magneteinrichtung eine elektrische Verbindung zwischen der Leiterbahn und zumindest einem Leiterabschnitt der Widerstandsbahn hergestellt wird.Very It is advantageous if the contact means at a distance from the resistance path or attached to the conductor sections on the carrier, because in this way only when exposed to the magnetic device an electrical Connection between the conductor track and at least one conductor section the resistance path is produced.
Auch vorteilhaft ist, dass das Kontaktmittel aus einem weichmagnetischen Metall hergestellt ist, da die einzelnen Biegeelemente des Kontaktmittels auf diese Weise von der Magneteinrichtung zu den Leiterabschnitten der Widerstandsbahn hin auslenkbar sind.Also It is advantageous that the contact means of a soft magnetic Made of metal, since the individual bending elements of the contact means this way from the magnet device to the conductor sections of the Resistance path are deflectable.
Desweiteren vorteilhaft ist, wenn die Magneteinrichtung auf der dem Kontaktmittel abgewandten Seite des Trägers beweglich angeordnet ist, da die Bewegung der Magneteinrichtung auf diese Weise berührungslos übertragbar ist.Furthermore is advantageous if the magnetic device on the contact means the opposite side of the carrier is movably arranged, since the movement of the magnetic device in this way contactless transferable is.
Darüber hinaus vorteilhaft ist, wenn auf der Seite des Trägers mit der Widerstandsbahn ein Deckel vorgesehen ist, der zumindest die Widerstandsbahn, die Leiterabschnitte, die Leiterbahn und das Kontaktmittel dicht überdeckt, da auf diese Weise eine flüssigkeitsdichte Kammer gebildet ist, in der die Widerstandsbahn, die Leiterbahn und das Kontaktmittel vor einer aggressiven Flüssigkeit geschützt sind. Eine Korrosion dieser Komponenten oder eine Belagbildung auf den Komponenten wird hierdurch sicher vermieden.About that It is also advantageous if on the side of the wearer with the resistance path a cover is provided, at least the resistance track, the conductor sections, the track and the contact means tightly covered, as in this way a liquid-tight Chamber is formed, in which the resistance path, the conductor track and the contact agent from an aggressive liquid are protected. Corrosion of these components or A buildup on the components is thereby safely avoided.
