Vorteilhaft an diesem Meßwiderstand ist, daß er einstückig ausgebildet ist und damit einen einfachen Aufbau aufweist. Nachteilig ist allerdings, daß die Herstellung einer Querschnittsverjüngung zur Realisierung des Widerstandsbereiches recht aufwendig ist.Advantageous on this measuring resistor is that he one piece is formed and thus has a simple structure. adversely is, however, that the Production of a cross-sectional taper for the realization of Resistance area is quite expensive.
Daher ergab sich die Aufgabe, einen Batteriesensor mit einem besonders einfachen und kostengünstigen Meßwiderstand zu schaffen, der auf einfache Weise an die Umgebung angekoppelt werden kann.Therefore the task arose, a battery sensor with a particularly simple and inexpensive measuring resistance to create that easily coupled to the environment can be.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Meßwiderstand einen Kern aus einem ersten Material mit einem gleichmäßigen Querschnitt und zwei mit dem Kern verbundene Hülsen aus einem zweiten Material aufweist, wobei das zweite Material niederohmiger ist als das erste Material.These Task is inventively characterized solved, that the measuring resistance a core of a first material with a uniform cross-section and two sleeves of a second material bonded to the core has, wherein the second material is lower resistance than the first Material.
Bei dem erfindungsgemäßen Batteriesensor besteht somit der Widerstandsbereich aus einem ersten Material mit einem über seine Länge konstanten Querschnitt, der beispielsweise quadratisch, rechteckig und vorzugsweise rund ausgebildet sein kann. Damit kann bei diesem Meßwiderstand auf eine aufwendige Formgebung des Widerstandsbereiches verzichtet werden; statt dessen kann dieser Abschnitt durch einfaches Zuschneiden eines stabförmigen Rohlings aus dem Widerstandsmaterial gefertigt werden.at consists of the battery sensor according to the invention Thus, the resistance range of a first material with a on his Length constant Cross-section, for example, square, rectangular and preferably can be trained. This can with this measuring resistor dispensed with a complex shape of the resistance area become; instead, this section can be easily cropped a rod-shaped Blanks are made of the resistance material.
Um besonders gut leitende Bereiche für die Stromzuführung zu realisieren, wird dieser Widerstandsbereich mit zwei besonders gut leitenden Hülsen aus einem niederohmigen Material fest verbunden. Durch die feste Verbindung, die auf vorteilhafte Weise durch Crimpen hergestellt werden kann, werden Übergangswiderstände zwischen den Hülsen und dem Kern vermieden.Around particularly good conductive areas for the power supply too Realize this resistance range with two particularly good conductive sleeves made of a low-resistance material firmly connected. By the solid Compound which is advantageously produced by crimping contact resistances are between the sleeves and avoided the core.
Um eine Abdichtung des Meßwiderstands gegen äußere Einflüsse zu erreichen, ist es vorteilhaft insbesondere den Überlappungsbereich zwischen dem Kern und den Hülsen mit einer Kunststoffumspritzung zu versehen. Diese Kunststoffumspritzung kann wiederum vorteilhaft ein Teil eines Sensorgehäuses ausbilden, welches beispielsweise eine Schaltungsanordnung zur Verarbeitung der am Meßwiderstand abfallenden Signalspannung aufnehmen kann.Around to achieve a seal of the measuring resistance against external influences it is advantageous in particular the overlap area between the core and the pods to be provided with a plastic extrusion. This plastic extrusion again can advantageously form part of a sensor housing, which, for example, a circuit arrangement for processing the at the measuring resistor can absorb falling signal voltage.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Batteriesensors sind in den Unteransprüchen beschrieben.Further advantageous embodiments and further developments of the battery sensor according to the invention are in the subclaims described.
Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung dargestellt und näher erläutert.in the The following will be an embodiment of Invention illustrated with reference to the drawing and explained in more detail.

Eine weitere, in den Figuren nicht dargestellte Möglichkeit zur Herstellung einer festen Verbindung zwischen dem Kern und den Hülsen besteht darin, diese miteinander zu verschrauben. Hierzu sind die Endabschnitte des Kerns und die Ausnehmungen der Hülsen jeweils mit einem Gewinde zu versehen.A further, not shown in the figures possibility of producing a firm connection between the core and the sleeves is to use these together to screw. For this purpose, the end portions of the core and the Recesses of the sleeves each to be provided with a thread.
