Die
Erfindung geht aus von einer Magnetsensoranordnung nach der Gattung
des unabhängigen
Anspruchs. Aus der
Offenbarung der Erfindungepiphany the invention
Die erfindungsgemäße Magnetsensoranordnung gemäß den Merkmalen des unabhängigen Anspruchs 1 hat demgegenüber den Vorteil, dass eine hohe Lagegenauigkeit des Magneten zu dem Magnetfelderfassungsmittel erreicht wird, sodass sich die Messgenauigkeit der Sensoranordnung verbessert. Die Lage der Magnetfelderfassungsmittel auf der Grundplatte und damit im Gesamtgehäuse wird durch die Fertigungseinrichtung bestimmt. Das Gehäuse wird durch eine Kunststoffumspritzung hergestellt mittels hochgenauer Werkzeuge. Die Lage der Kammer zur Aufnahme des Magneten in dem Gehäuse ist somit festgelegt. Die Lage des Magneten ist nur von diesen Toleranzen abhängig. Die Kammer erzeugt erfindungsgemäß einen sicheren Halt des Magneten während der Aushärtung des Klebers zur Befestigung des Magneten in dem Gehäuse. Dadurch verbessert sich die Positioniergenauigkeit. Zudem hat die erfindungsgemäße Vorrichtung den Vorteil, dass lediglich durch Austausch einer Hälfte des Spritzwerkzeugs die entsprechende Kammer mit erfindungsgemäßen Führungsmitteln zu jedem Standardgehäuse hinzugefügt werden kann. Kosten entstehen hierbei nur für eine Werkzeughälfte. Die Fertigungslinie ist jedoch bis zum Umspritzprozess eine Standardfertigung.The Magnetic sensor arrangement according to the invention according to the characteristics of the independent Claim 1 has the opposite the advantage that a high positional accuracy of the magnet to the Magnetic field detecting means is achieved, so that the measuring accuracy the sensor arrangement improved. The location of the magnetic field detecting means on the base plate and thus in the overall housing is by the manufacturing facility certainly. The housing is made by a plastic extrusion by means of high precision Tools. The location of the chamber for receiving the magnet in the casing is thus determined. The position of the magnet is only from these tolerances dependent. The chamber produces according to the invention secure hold of the magnet during the curing the adhesive for fixing the magnet in the housing. This improves the positioning accuracy. In addition, the device according to the invention the advantage that only by replacing one half of the injection mold the corresponding chamber with guide means according to the invention are added to each standard housing can. Costs arise only for a tool half. The However, the production line is a standard production until the injection molding process.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass als Führungsmittel eine Abschrägung der Kammer vorgesehen ist, die als Führungsfläche für den Magneten dient. Dadurch wird sichergestellt, dass sich der Magnet schnell und positionsgenau in der Kammer platzieren lässt.In an appropriate training is provided that as a guide a bevel of Chamber is provided, which serves as a guide surface for the magnet serves. This will ensure that the magnet moves quickly and position accurately in the chamber.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass als Führungsmittel eine am Magneten angebrachte Schräge vorgesehen ist, die mit der Abschrägung der Kammer zusammenwirkt. Dadurch kann eine noch genauere Positionierung des Magneten in der Kammer vorgenommen werden.In an appropriate training is provided that as a guide a magnet-mounted slope is provided with the the bevel the chamber interacts. This allows an even more accurate positioning of the magnet in the chamber.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass die Abschrägung und die Schräge den selben Winkel aufweisen gegenüber der Oberfläche des Magnetfelderfassungsmittels. Dadurch wird insbesondere eine parallele Ausrichtung der Oberflächen des Magneten und des Magnetfelderfassungsmittels erreicht.In an appropriate training is provided that the bevel and the slope the have the same angle opposite the surface of the magnetic field detection means. This will especially a parallel alignment of the surfaces reaches the magnet and the magnetic field detection means.
Weitere zweckmäßige Weiterbildungen ergeben sich aus weiteren abhängigen Ansprüchen und aus der Beschreibung.Further appropriate training arise from other dependent Claims and from the description.
