Abstract
Description
Die Erfindung betrifft eine Sensor-Baugruppe, bei welcher ein Sensor an einer vorbestimmten Position in einem Bauteil befestigt ist.The The invention relates to a sensor assembly in which a sensor attached to a predetermined position in a component.
Sensor-Baugruppen, bei denen die Sensorposition in einem Bauteil genau vorgegeben werden sollte, sind in vielfältigen Varianten durch offenkundige Vorbenutzung bekannt. Zur Messung der Stromstärke in einem elektrischen Leiter können beispielsweise Hallsensoren verwendet werden, bei denen es auf eine exakte Positionierung ankommt. Die in diesen induzierte elektrische Spannung ist proportional zur Stärke des Magnetfelds, welches durch den im Leiter fließenden Strom erzeugt wird. Zur besseren Erfassung des Magnetfelds wird beispielsweise ein weichmagnetischer Kern, welcher den Leiter umfasst und die magnetischen Feldlinien in seinem Inneren konzentriert, verwendet. Der Kern weist vorteilhaft einen im wesentlichen senkrecht zu den magnetischen Feldlinien verlaufenden Luftspalt auf, welcher als Aufnahmeraum für den Hallsensor dient. Um den Sensor gegen unerwünschtes Verrutschen im Bauteil zu sichern, wird dieser üblicherweise mit dem Bauteil verklebt. Dies ist in vielen Einsatzbereichen, z.B. bei hohen Temperaturen, nicht möglich.Sensor Units, where the sensor position in a component should be specified exactly are in diverse Variants known by public prior use. To measure the amperage in an electrical conductor For example, Hall sensors are used, where it is on a exact positioning arrives. The induced in these electrical Tension is proportional to the strength the magnetic field, which by the current flowing in the conductor is produced. For better detection of the magnetic field, for example a soft magnetic core comprising the conductor and the magnetic Field lines concentrated in its interior, used. The core points advantageously a substantially perpendicular to the magnetic field lines extending air gap, which as a receiving space for the Hall sensor serves. To the sensor against unwanted To ensure slippage in the component, it is usually glued to the component. This is in many applications, e.g. at high temperatures, not possible.
Es ist daher eine Aufgabe der vorliegenden Erfindung, eine zuverlässige, insbesondere temperaturstabile Sensor-Baugruppe für Sensoren zu schaffen.It is therefore an object of the present invention, a reliable, in particular Temperature-stable sensor assembly for sensors to create.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.These The object is achieved by the Characteristics of claim 1 solved.
Der Kern der Erfindung besteht darin, einen Sensor, insbesondere einen Magnetfeldsensor, mit Hilfe einer Halterung auf einer Leiterplatte an einer vorbestimmten Position zu befestigen und danach die Leiterplatte mit einem Bauteil, beispielsweise durch eine Schraubverbindung, fest zu verbinden, wobei die Halterung passgenau in eine eigens dafür vorgesehene Ausformung eingesteckt wird. Die exakte Relativpositionierung des Sensors zum Bauteil ist daher gewährleistet, ohne dass der Sensor direkt, z.B. durch stoff- oder formschlüssige Verbindung mit dem Bauteil verbunden wird. Die Verbindung erfolgt vielmehr indirekt über die Halterung und die Leiterplatte. Der Sensor kann insbesondere formschlüssig an der Halterung und/oder der Leiterplatte gehalten sein. Der Sensor kann dann exakt gegenüber der Leiterplatte positioniert werden, ohne dass bei der Verbindung des Sensors mit der Halterung der Sensor Umgebungsbedingungen ausgesetzt werden muss, für die er nicht ausgelegt ist.Of the The core of the invention is a sensor, in particular a Magnetic field sensor, using a holder on a printed circuit board to fix at a predetermined position and then the circuit board with a component, for example by a screw connection, firmly connect, with the holder fit into a special intended for this purpose Forming is inserted. The exact relative positioning of the Sensor to the component is therefore guaranteed without the sensor directly, e.g. by material or positive connection with the component is connected. The connection takes place indirectly over the Bracket and the circuit board. The sensor can in particular form-fitting manner be held the holder and / or the circuit board. The sensor can then be exactly opposite the circuit board can be positioned without being connected of the sensor with the holder of the sensor exposed to ambient conditions must be, for he is not designed.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the Dependent claims.
Das Anlöten der Halterung auf der Leiterplatte gemäß Anspruch 2 bzw. das reibschlüssige Anbringen der Halterung mittels Stützpins auf der Leiterplatte gemäß Anspruch 3, die Steckverbindung des Sensors mit der Halterung gemäß Anspruch 4 sowie die Lötverbindung der Kontaktpins des Sensors mit der Leiterplatte gemäß Anspruch 5 ermöglichen ein einfaches und sicheres Anbringen des Sensors, welcher unter Umständen sehr empfindlich ist, auf der Leiterplatte.The solder on the holder on the circuit board according to claim 2 or the frictional attachment the holder by means of support pins on the circuit board according to claim 3, the connector of the sensor with the holder according to claim 4 and the solder joint the contact pins of the sensor with the circuit board according to claim 5 allow a simple and secure attachment of the sensor, which under circumstances very sensitive, on the circuit board.
Die Verbindung der Leiterplatte mit dem Bauteil durch Verschrauben, Vernieten oder Verschweißen bzw. Verkleben gemäß Ansprüchen 6 bis 8 stellt eine besonders sichere Verbindung zwischen der Leiterplatte und dem Bauteil dar.The Connection of the printed circuit board to the component by screwing, Riveting or welding or bonding according to claims 6 to 8 provides a particularly secure connection between the circuit board and the component.
