Description
Die vorliegende Erfindung betrifft eine Messanordnung mit einem Messwiderstand.The present invention relates to a measuring arrangement with a measuring resistor.
Stand der TechnikState of the art
Aus dem Stand der Technik sind Batteriepolklemmenanordnungen mit integrierten Strommessschaltungen zum Erfassen des Stromflusses aus der Batterie bekannt. Eine gattungsgemäße Messanordnung ist beispielsweise in der
Üblicherweise benötigen Batteriesensoren eine elektrisch leitende Verbindungstechnik zwischen dem Shunt und dem Messkabel, welche oft durch eine Schraubenverbindung realisiert ist. Am Einbauort des Batteriesensors im Fahrzeug ist der Sensor dem Einfluss von Wasser, Salzwasser und auch anderen Medien ausgesetzt. Die können je nach gewählten metallischen Materialien der Aufbau- und Verbindungstechnik teils stark korrosive Reaktionsprodukte erzeugen, welche die üblicherweise verwendeten Kunststoffe angreifen und schädigen können.Usually battery sensors require an electrically conductive connection technology between the shunt and the measuring cable, which is often realized by a screw connection. At the installation site of the battery sensor in the vehicle, the sensor is exposed to the influence of water, salt water and other media. Depending on the chosen metallic materials, they can sometimes produce highly corrosive reaction products that can attack and damage commonly used plastics.
Immer weiterführende Miniaturisierung wie im Stand der Technik gezeigt führt durch das Zusammenrücken von beispielsweise Schraubverbindungen zum Gehäuse zum wachsenden Einfluss solcher Korrosionsprodukte auf das Gehäuse. Aufgrund der Einbauposition an der Batterie, insbesondere an der Blei-Säure-Batterie, besteht ebenfalls die Anforderung an Beständigkeit gegenüber Batteriesäure, welche ebenfalls für viele Kunststoffe schädigend ist. Bisher verwendete Kunststoffe stellen an die chemische Beständigkeit stets einen Kompromiss dar.Continuing miniaturization, as shown in the prior art, leads to the increasing influence of such corrosion products on the housing due to the tightening of, for example, screw connections to the housing. Due to the installation position on the battery, in particular on the lead-acid battery, there is also the requirement of resistance to battery acid, which is also damaging to many plastics. Previously used plastics are always a compromise to chemical resistance.
Es ist Aufgabe der vorliegenden Erfindung, den Schutz der Messanordnung weiter zu verbessern. Diese Aufgabe wird gelöst durch die Merkmale des unabhängigen Anspruchs.It is an object of the present invention to further improve the protection of the measuring arrangement. This object is solved by the features of the independent claim.
Offenbarung der ErfindungDisclosure of the invention
Die erfindungsgemäße Vorrichtung mit den Merkmalen des unabhängigen Anspruchs hat demgegenüber den Vorteil, dass die Messanordnung besonders gut geschützt ist sowohl gegenüber Säuren wie auch starken Laugen. Dies wird erfindungsgemäß dadurch erreicht, dass das Gehäuse des Batteriesensors aus Polyketon aufgebaut ist. Polyketon zeichnet sich durch bessere chemische Beständigkeit aus. Es hat sich überraschender Weise herausgestellt, dass sich der Werkstoff Polyketon gerade für die Verwendung bei Batteriesensoren besonders eignet.The device according to the invention with the features of the independent claim has the advantage that the measuring arrangement is particularly well protected against both acids and strong alkalis. This is inventively achieved in that the housing of the battery sensor is constructed of polyketone. Polyketone is characterized by better chemical resistance. It has surprisingly been found that the material polyketone is especially suitable for use in battery sensors.
Weitere zweckmäßige Weiterbildungen ergeben sich aus weiteren abhängigen Ansprüchen und aus der Beschreibung.Further expedient developments emerge from further dependent claims and from the description.
