Der Erfindung liegt die Aufgabe zugrunde, eine kostengünstige Verbindung von Messwiderstand mit Kabel zu erreichen. Diese Aufgabe wird gelöst durch die Merkmale des unabhängigen Anspruchs.Of the Invention is based on the object, a cost-effective Connection of measuring resistor with cable to achieve. This task is solved by the characteristics of the independent Claim.
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Vorrichtung zur Ermittlung eines elektrischen Stroms gemäß den Merkmalen des unabhängigen Anspruchs hat dem gegenüber den Vorteil, dass auf Grund der übereinander liegenden Anordnung von Kabel und Messwiderstand eine elektrisch leitende Verbindung zwischen den beiden Elementen leicht hergestellt werden kann. Dies reduziert die Herstellkosten und vereinfacht die Herstellung der Vorrichtung. So könnte der Messwiderstand beispielsweise zwischen zwei Kabelenden gepresst oder eventuell kompaktiert werden. Dadurch, dass große Kräfte auf die Verbindung aufgebracht werden können, erleichtert sich auch die elektrisch leitende Kontaktierung zwischen Kabel und Messwiderstand.The Inventive device for determining a electric current according to the characteristics of the independent Claim has the advantage over that on reason the superimposed arrangement of cable and measuring resistor an electrically conductive connection between the two elements can be easily made. This reduces the manufacturing costs and simplifies the manufacture of the device. So could the measuring resistor, for example, pressed between two cable ends or possibly compacted. Because of that big Forces can be applied to the connection also facilitates the electrically conductive contact between Cable and measuring resistor.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass zwischen dem ersten Kabel und dem Messwiderstand sowie zwischen dem zweiten Kabel und der anderen Kontaktfläche des Messwiderstands jeweils Kontaktierelemente, wie beispielsweise Pins oder sonstige Leiter, eingebracht werden und im Rahmen der Kontaktierung der Elemente mit verpresst werden. Über diese Kontaktierelemente können die beiden elektrischen Potenziale am Messwiderstand abgegriffen werden, deren Potenzialdifferenz ein Maß für den elektrischen Strom darstellt. Über diese Kontaktierelemente kann die elektrische Verbindung zu einer die entsprechende Auswertung durchführenden Elektronik hergestellt werden. Diese Elektronik könnte dann das so ermittelte Signal für den fließenden Strom über weitere Signalleitungen beispielsweise an ein übergeordnetes Steuergerät abgeben. Die Integration der Kontaktierelemente in die beiden ohnehin zu kontaktierenden Kontaktflächen erlaubt eine Herstellung oder Verbindung lediglich in einem Arbeitsgang.In an expedient development is provided that between the first cable and the measuring resistor as well as between the second cable and the other contact surface of the measuring resistor respectively Contacting elements, such as pins or other conductors, be introduced and in the context of contacting the elements be pressed with. About these contacting elements can tapped the two electrical potentials on the measuring resistor whose potential difference is a measure of represents electric current. About these contacting elements the electrical connection can lead to a corresponding evaluation Electronics are produced. This electronics could then the signal thus obtained for the flowing Power over other signal lines, for example, to a parent Dispense control unit. The integration of contacting elements in the two contact surfaces to be contacted anyway allows a production or connection only in one operation.
In einer zweckmäßigen Weiterbildung können die beiden elektrischen Potenziale durch eine entsprechende Führung der Litzen der beiden Kabel an die Elektronik weitergeleitet werden. Damit kann vorzugsweise auf zusätzliche Kontaktierele mente, welche erst wieder in die Verbindung mit eingefügt werden müssten, verzichtet werden.In an appropriate training the two electrical potentials by an appropriate leadership the strands of the two cables are forwarded to the electronics. This may preferably on additional Kontaktierele elements, which would have to be reinserted into the connection be waived.
In einer zweckmäßigen Weiterbildung ist vorgesehen, dass die Kabelisolierung auch über den Messwiderstand geführt wird. Dadurch lässt sich die Robustheit der Vorrichtung erhöhen und eine verbesserte Dichtheit erreichen.In an expedient development is provided that the cable insulation also passed over the measuring resistor becomes. This allows the robustness of the device increase and achieve improved tightness.
Die beschriebene Vorrichtung erhöht die Flexibilität hinsichtlich des Einbauorts, da nun der Messwiderstand nicht mehr zwingend in der Polnische der Batterie untergebracht werden muss.The described device increases the flexibility with regard to the installation site, as now the measuring resistor is no longer mandatory in the Polish of the battery must be accommodated.
Weitere zweckmäßige Weiterbildungen ergeben sich aus weiteren abhängigen Ansprüchen und aus der Beschreibung.Further expedient developments emerge from further dependent claims and the description.
