Darüber hinaus wird jedoch auch die Motorstarteinrichtung unter dem Begriff eines Verbrauchers gefasst.Under An electrical consumer of a vehicle will be both classic Consumers such as radio, lighting units, windscreen heating, Airbag and the like understood. In addition, however, will too the engine starting device is taken under the concept of a consumer.
Das Widerstandselement ist bevorzugt zumindest anteilig aus Manganin ausgebildet. Im Unterschied zum Stand der Technik ist somit nicht mehr erforderlich, ein großes einstückiges Element umfassend eine Polklemme und eine Stromträgerplatte aus diesem relativ teuren Material herzustellen oder dieses in aufwändiger Weise in dieses einstückige Element einzubetten. Ein aus Manganin hergestelltes Verbindungsstück zwischen den zwei separaten Teilen der Polklemme ermöglicht eine zumindest entsprechende Funktionalität bei deutlich reduzierten Kosten und erheblich reduziertem Fertigungsaufwand.The Resistance element is preferably at least proportionally of manganin educated. In contrast to the prior art is thus not more needed, a big one one-piece Element comprising a pole terminal and a current-carrying plate make this relatively expensive material or this in a complex manner in this one-piece Embed element. A manganese-made connector between the two separate parts of the pole terminal allows at least corresponding functionality at significantly reduced costs and significantly reduced production costs.
Bevorzugt ist der Verbindungsbereich zwischen den beiden Teilen der Polklemme und dem Widerstandselement feuerverzinnt. Zumindest die an das Widerstandselement angrenzenden Bereiche der beiden Teile der Polklemme sowie das Widerstandselement selbst werden somit bevorzugt feuerverzinnt, wobei durch dieses Verlöten eine hohe mechanische Festigkeit und eine gute Stromtragfähigkeit erreicht wird.Prefers is the connection area between the two parts of the pole terminal and the resistive element hot tinned. At least that of the resistance element adjacent areas of the two parts of the pole terminal and the resistance element itself are thus preferably hot tinned, which is characterized by this Solder a high mechanical strength and a good current carrying capacity is reached.

Insbesondere bei einer allseitigen umlaufenden Abfräsung kann die Messwerterfassung erheblich verbessert werden. Die Breite der Abfräsung der Zinnschicht beträgt bevorzugt etwa 4mm.Prefers is this tin layer after application by a milling process processed. In particular, the tin layer is by a milling, in particular by a circumferential notch, except for the material of the resistive element severed. A current flow between the two parts of the pole terminal over the Tin layer can be prevented. Leave the readings thereby significantly improve. Especially with an all-round circumferential milling the measured value acquisition can be considerably improved. The width the milling the tin layer is preferably about 4mm.
Darüber hinaus kann durch diese mechanische Bearbeitung auch der Querschnitt dieser durch das Widerstandselement erzeugten Brücke verändert werden, wodurch der elektrische Widerstand justiert werden kann.
