Description
Die Erfindung betrifft eine elektrische Sicherungsvorrichtung für mit einer Batterie verbundene elektrische Verbraucher eines Fahrzeugs, mit einer unmittelbar an einen Pol einer Fahrzeugbatterie anschließbaren Polklemme und einer Elektronikeinheit zur Erfassung von Batteriezustandsgrößen.The invention relates to an electrical safety device for connected to a battery electrical load of a vehicle, with a directly connectable to a pole of a vehicle battery terminal and an electronic unit for detecting battery state variables.
Für viele von der Batterie eines Kraftfahrzeugs versorgte elektrische Verbraucher dieses Fahrzeugs ist es erforderlich, sie mittels elektrischer Sicherungen zu schützen. Dabei muss auch die zur Verbindung zwischen der Batterie und Motorstarteinrichtung, dem Anlasser des Fahrzeugs vorgesehene Anlasserleitung aufgrund der über sie fließenden Ströme mit hohen Stromstärken mit einer entsprechenden elektrischen Sicherung abgesichert werden.For many powered by the battery of a motor vehicle electrical consumer of this vehicle, it is necessary to protect them by means of electrical fuses. In this case, the provided for the connection between the battery and the engine starter, the starter of the vehicle starter line must be hedged due to the current flowing through them with high currents with a corresponding electrical fuse.

Die bekannte Ausführung eines einstückigen Elements ist relativ kostenintensiv und sehr aufwändig in der Herstellung. Insbesondere bei einer kompletten Ausbildung des einstückigen Elements aus Manganin ist dies sehr teuer. Auch die integrale Einbettung eines derartigen Materialbereichs in ein einstückiges Element ist sehr aufwändig und sehr schwer zu realisieren.The known embodiment of a one-piece element is relatively expensive and very expensive to manufacture. In particular, in a complete design of the one-piece element of manganin this is very expensive. The integral embedding of such a material region in a one-piece element is very complex and very difficult to implement.

Daher ist es Aufgabe der vorliegenden Erfindung, eine elektrische Sicherungsvorrichtung zu schaffen, welche aufwandsarm und kostenreduziert bereitgestellt werden kann.It is therefore an object of the present invention to provide an electrical safety device, which can be provided with little effort and cost reduced.
Diese Aufgabe wird durch eine elektrische Sicherungsvorrichtung, welche die Merkmale nach Patentanspruch 1 aufweist, gelöst.This object is achieved by an electrical safety device having the features of claim 1.
Eine erfindungsgemäße elektrische Sicherungsvorrichtung für mit einer Batterie verbundene elektrische Verbraucher eines Fahrzeugs umfasst eine unmittelbar an einen Pol einer Batterie anschließbare Polklemme und eine Elektronikeinheit zur Erfassung von Batteriezustandsgrößen. Die Polklemme ist zumindest zweiteilig ausgebildet und umfasst somit zwei separate Teile, welche mit einem separaten elektrischen Widerstandselement verbunden sind. Das elektrische Widerstandelement dient somit als Verbindungselement zwischen den zwei beabstandet zueinander angeordneten Teilen der Polklemme. Dadurch kann eine deutlich günstigere Ausgestaltung ermöglicht werden, welche darüber hinaus relativ einfach hergestellt werden kann und hohe Zuverlässigkeit und Funktionalität gewährleistet.An electrical safety device according to the invention for electrical consumers of a vehicle connected to a battery comprises a pole terminal which can be connected directly to one pole of a battery and an electronic unit for detecting battery state variables. The pole terminal is formed at least in two parts and thus comprises two separate parts, which are connected to a separate electrical resistance element. The electrical resistance element thus serves as a connecting element between the two spaced-apart parts of the pole terminal. As a result, a significantly more favorable configuration can be made possible, which, moreover, can be manufactured relatively simply and ensures high reliability and functionality.
Unter einem elektrischen Verbraucher eines Fahrzeugs werden sowohl klassische Verbraucher wie beispielsweise Radio, Lichteinheiten, Frontscheibenheizung, Airbag und dergleichen verstanden. Darüber hinaus wird jedoch auch die Motorstarteinrichtung unter dem Begriff eines Verbrauchers gefasst.An electrical consumer of a vehicle is understood as meaning both classic consumers such as, for example, radio, light units, windscreen heating, airbag and the like. In addition, however, the engine starting device is also taken under the name 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 formed at least proportionally of manganin. In contrast to the prior art, it is therefore no longer necessary to produce a large one-piece element comprising a pole clamp and a current-carrying plate made of this relatively expensive material or to embed it in a complex manner in this one-piece element. A made of Manganin connector between the two separate parts of the terminal clamp allows at least corresponding functionality at significantly reduced costs and significantly reduced manufacturing costs.
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.The connection area between the two parts of the pole terminal and the resistance element is fire-tinned. At least the regions of the two parts of the pole terminal adjacent to the resistance element as well as the resistance element itself are thus preferably hot-dip-tinned, a high mechanical strength and a good current-carrying capacity being achieved by this soldering.
Diese Zinnschicht ist nach dem Aufbringen durch einen Fräsvorgang bearbeitet. Die Zinnschicht ist durch eine Fräsung, insbesondere durch eine umlaufende Einkerbung, bis auf das Material des Widerstandselements durchtrennt. Ein Stromfluss zwischen den beiden Teilen der Polklemme über die Zinnschicht kann dadurch verhindert werden. Die Messwerte lassen sich dadurch erheblich verbessern. Insbesondere bei einer allseitigen umlaufenden Abfräsung kann die Messwerterfassung erheblich verbessert werden. Die Breite der Abfräsung der Zinnschicht beträgt bevorzugt etwa 4 mm. This tin layer is processed after application by a milling process. The tin layer is cut through a milling, in particular by a circumferential notch, down to the material of the resistive element. A current flow between the two parts of the pole terminal on the tin layer can be prevented. The measured values can be considerably improved thereby. In particular, in the case of all-round circumferential milling, the measurement value acquisition can be considerably improved. The width of the milling of the tin layer is preferably about 4 mm.
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. Die Querschnittfläche des Widerstandselements beträgt bevorzugt zwischen 32 mm2 und 38 mm2, insbesondere 35 mm2.In addition, by this mechanical processing, the cross section of this bridge generated by the resistance element can be changed, whereby the electrical resistance can be adjusted. The cross-sectional area of the resistance element is preferably between 32 mm 2 and 38 mm 2 , in particular 35 mm 2 .
An dem Widerstandselement sind bevorzugterweise Kontaktstifte, insbesondere zwei Kontaktstifte, angeordnet, welche zur elektrischen Kontaktierung der Elektronikeinheit ausgebildet sind. Bevorzugt sind diese Kontaktstifte an einer Unterseite des Widerstandselements angeordnet und ermöglichen eine elektrische Kontaktierung mit dem unmittelbar darunter angeordneten Elektronikmodul. Dadurch kann eine bauraumoptimierte Ausgestaltung ermöglicht werden. Nicht zuletzt kann dadurch auch die Kompaktheit und die Stabilität verbessert werden.On the resistive element are preferably contact pins, in particular two contact pins, arranged, which are designed for electrical contacting of the electronic unit. Preferably, these contact pins are arranged on an underside of the resistance element and allow electrical contacting with the electronics module arranged directly underneath. This allows a space-optimized design possible. Last but not least, this can also improve the compactness and stability.
Bevorzugt sind die Kontaktstifte an dem Widerstandselement angeschweißt. Dadurch kann die mechanische Belastbarkeit erhöht werden und eine besonders stabile Ausgestaltung bereitgestellt werden.Preferably, the contact pins are welded to the resistive element. As a result, the mechanical load capacity can be increased and a particularly stable design can be provided.
Die Elektronikeinheit ist bevorzugterweise lösbar an einem Gehäuse der Sicherungsvorrichtung angeordnet. Es kann dabei vorgesehen sein, dass die Elektronikeinheit an dem Gehäuse verrastend oder eingeklippst befestigt ist. Dadurch kann eine sichere Anbringung gewährleistet werden und dennoch ein schnelles Lösen zum Austauschen oder dergleichen durchgeführt werden. Die Elektronikeinheit, welche auch als Batteriemanager fungiert, kann somit in einer als Zentralabsicherung ausgebildeten Sicherungsvorrichtung integriert sein.The electronics unit is preferably detachably arranged on a housing of the securing device. It may be provided that the electronics unit is attached to the housing latching or clipped. Thereby, a secure attachment can be ensured and yet a quick release for replacement or the like can be performed. The electronics unit, which also acts as a battery manager, can thus be integrated in a safety device designed as a central protection device.
Die Elektronikeinheit bzw. der Batteriemanager kann mit dem Minuspol der Batterie über eine Signalleitung verbunden sein. Darüber hinaus ist die Elektronikeinheit bevorzugt über eine Steckverbindung mit weiteren Fahrzeugelektronikkomponenten elektrisch verbindbar.The electronics unit or the battery manager can be connected to the negative pole of the battery via a signal line. In addition, the electronics unit is preferably electrically connectable via a plug connection with other vehicle electronic components.
Jedes der beiden separaten Teile der Polklemme weist in bevorzugter Weise einen Aufnahmebereich auf, in welchen das Widerstandselement bereichsweise eingesetzt ist. Eine zuverlässige Halterung und mechanisch stabile Verbindung kann dadurch geschaffen werden. Es kann vorgesehen sein, dass das Widerstandselement in den Aufnahmebereich formschlüssig und/oder kraftschlüssig eingesetzt ist.Each of the two separate parts of the pole terminal preferably has a receiving region in which the resistance element is used in regions. A reliable holder and mechanically stable connection can be created. It can be provided that the resistance element is inserted into the receiving area in a form-fitting and / or non-positive manner.
Bevorzugt ist ein Aufnahmebereich als Nut, insbesondere als T-Nut, ausgebildet. Der Aufnahmebereich kann jedoch auch keilförmig ausgebildet sein. In symmetrischer Ausbildung ist das Widerstandselement somit beidseitig in einen jeweils keilförmigen Aufnahmebereich eingesetzt, wodurch in der Gesamtbetrachtung ein schwalbenschwanzförmiger Verbindungsbereich erzeugbar ist. Gerade eine derartige verzahnte Verbindung ermöglicht eine sichere Halterung und eine zuverlässige Verbindung der beiden Teile durch das elektrische Widerstandselement.Preferably, a receiving area is designed as a groove, in particular as a T-slot. However, the receiving area may also be wedge-shaped. In symmetrical design, the resistance element is thus used on both sides in a respective wedge-shaped receiving area, whereby in the overall view, a dovetail-shaped connection area can be generated. Just such a toothed connection allows secure mounting and reliable connection of the two parts by the electrical resistance element.
Das elektrische Widerstandselement ist insbesondere bei einer Ausgestaltung aus Manganin bevorzugt als Strangpressprofil oder Schmiedeteil ausgebildet. Durch diese spezifischen Teile kann den Anforderungen des Widerstandselements im Betrieb der elektrischen Sicherungsvorrichtung genüge getan werden. Derartige Teile können relativ hoch beansprucht werden und verschleißen weniger schnell.The electrical resistance element is preferably designed as an extruded profile or forged part, in particular in one embodiment of Manganin. Through these specific parts, the requirements of the resistive element in the operation of the electrical safety device can be done. Such parts can be relatively high stress and wear less quickly.
