Description

Die Erfindung betrifft einen Polklemmenverbund und einen Bolzen für einen solchen Polklemmenverbund sowie ein Verfahren zum Anbringen eines Isolierkörpers an einen Bolzen und ein Verfahren zum Bestücken einer Polklemme mit einem Bolzen.The invention relates to a Polklemmenverbund and a bolt for such a Polklemmenverbund and a method for attaching an insulating body to a bolt and a method for populating a pole terminal with a bolt.

Stand der TechnikState of the art

Die stetig wachsende Zahl an elektrischen Verbrauchern in modernen Kraftfahrzeugen führt zu einer deutlich steigenden Zahl von Feldausfällen, wie bspw. Liegenbleiber, aufgrund zu stark entladener oder defekter Batterien. Dies erfordert zunehmend den Einsatz von Energiemanagement-Systemen in Verbindung mit einer zuverlässigen Batteriezustandserkennung, welche die benötigten Batterie-Informationen aus den messbaren Batteriegrößen Strom, Spannung und Temperatur zur Verfügung stellt.The steadily growing number of electrical consumers in modern motor vehicles leads to a significant increase in the number of field failures, such as lying down, due to over-discharged or defective batteries. This increasingly requires the use of energy management systems in conjunction with a reliable battery condition detection, which provides the required battery information from the measurable battery sizes current, voltage and temperature.

Weiterhin zeichnet sich in der Automobilindustrie eine Trendwende in Richtung intelligenter Batteriesensoren ab, welche die Batteriegrößen Strom, Spannung und Temperatur mit hoher Genauigkeit und Abtastrate erfassen und, je nach Partitionierung, teilweise oder vollständig die Aufgabe der BatterieZustandserkennung übernehmen. Das elektrische Energie-Management befindet sich dabei typischerweise in einem Host-Steuergerät, wie bspw. einem Body Computer, Gateway, Motor-Steuergerät, usw., das mit dem Batterie-Sensor über eine einfache und kostengünstige serielle Schnittstelle, vorzugsweise einem LIN (Local Interconnect Network), kommuniziert.Furthermore, in the automotive industry there is a trend reversal in the direction of intelligent battery sensors, which record the battery sizes current, voltage and temperature with high accuracy and sampling rate and, depending on the partitioning, partially or completely take on the task of battery state detection. The electrical energy management is typically located in a host controller, such as a body computer, gateway, engine controller, etc. connected to the battery sensor via a simple and inexpensive serial interface, preferably a LIN (Local Interconnect Network), communicates.

Derartige kostengünstig zu realisierende Konzepte ermöglichen den Einsatz von Energiemanagement-Systemen zukünftig auch in Fahrzeugen der Mittelklasse und in Kleinwagen.Such inexpensive to implement concepts allow the use of energy management systems in the future, even in middle-class vehicles and in small cars.

Mit zunehmender Verbreitung dieser Systeme sind flexible und kompakte Lösungen gefragt, um verschiedene Fahrzeugvarianten mit einem Mechanikkonzept bedienen zu können. Dabei wird angestrebt, diese Sensoren in der Batteriepol-Nische zu integrieren.With the increasing popularity of these systems, flexible and compact solutions are required in order to be able to serve different vehicle variants with a mechanical concept. The aim is to integrate these sensors in the battery-pole niche.

Derzeit basiert die Mechanik der Batterie-Sensoren auf einer Polklemme, einem Shunt bzw. Messwiderstand, einem Massekabelanschluss und einer integrierten Elektronik. Um Zugkräfte am Batteriekabel aufzunehmen, werden unter anderem bereits isolierte Schraubverbindungen eingesetzt. Unterschiedliche Konzepte sind hierfür auf dem Markt erhältlich. Des weiteren sind Schraubbolzen in Polklemmen weit verbreitet. Diese Schraubbolzen sind fest und elektrisch leitend in der Polklemme integriert.Currently, the mechanics of the battery sensors are based on a pole terminal, a shunt or measuring resistor, a ground cable connection and integrated electronics. In order to absorb tensile forces on the battery cable, inter alia already insulated screw connections are used. Different concepts are available for this purpose in the market. Furthermore, bolts are widely used in pole terminals. These bolts are firmly and electrically conductive integrated in the pole terminal.

Unter einer Polklemme ist eine steck- oder schraubbare Verbindung zum Anschluss von Kabeln an einzelnen Kontakten elektrischer Geräte oder Baugruppen zu verstehen. Je nach Ausführung ist mit dieser eine mit oder ohne Werkzeug lösbare stromleitende Verbindung zu realisieren.A pole terminal is to be understood as a pluggable or screwable connection for connecting cables to individual contacts of electrical devices or assemblies. Depending on the design, a power-conducting connection which can be released with or without a tool can be realized with this.

Bei bekannten Sensorkonzepten werden Zugkräfte am Batteriekabel über die Polklemme abgeleitet. Die Fixierung zur Kraftübertragung auf die Polklemme soll die Elektronik vor mechanischer Belastung schützen.In known sensor concepts tensile forces are derived on the battery cable via the pole terminal. The fixation for power transmission to the pole terminal to protect the electronics from mechanical stress.

Eine Isolierung ist zwischen dem Masseanschluss und der Klemme an dieser Stelle notwendig, um die Funktionalität des Batteriesensors zu gewährleisten. Es ist eine Lösung bekannt, bei der die Isolierung als Unterlegscheibe an der Polklemme verschraubt ist. Das hat zur Folge, dass eine Verliersicherung der Isolierplatte nicht gewährleistet ist.Insulation is required between the ground terminal and the terminal at this point to ensure the functionality of the battery sensor. It is known a solution in which the insulation is screwed as a washer on the pole terminal. This has the consequence that a captive securing the insulating plate is not guaranteed.

Weiterhin ist es bekannt, die Isolierung um den Bolzen herum anzuspritzen. Dies erfordert jedoch Spritzgusswerkzeuge, die in Abhängigkeit der Geometrie der Polklemmen unterschiedlich ausgelegt sein müssen.Furthermore, it is known to inject the insulation around the bolt around. However, this requires injection molding tools that must be designed differently depending on the geometry of the pole terminals.

Des weiteren sind Polklemmen bekannt, die keine Isolierung am Bolzen aufweisen. Bei diesen ist eine Isolierung im Batteriesensor integriert, was zusätzlichen Bauraum erforderlich macht.Furthermore, pole terminals are known which have no insulation on the bolt. In these, an insulation in the battery sensor is integrated, which requires additional space.

Eine Polklemme, die u.a. einen Bolzen trägt, wird nachfolgend als Polklemmenverbund bezeichnet.A pole clamp, which u.a. carries a bolt, hereinafter referred to as Polklemmenverbund.

Aus der Druckschrift DE 10 2009 000 827 A1 ist eine Vorrichtung zur Verbindung zweier elektrischer Anschlüsse einer Polklemme und eines Messelements bekannt. Die beiden Anschlüsse sind mittels Durchsetzfügens miteinander verbunden. Dabei kann einer der Anschlüsse eine Öffnung aufweisen, in die der andere Anschluss mittels Durchsetzfügens verformt ist. Es ist weiterhin beschrieben, dass die Öffnung eine Anfasung aufweisen kann, in die der andere Anschluss mittels Durchsetzfügens gepresst wird, so dass sich ein Hinterschnitt ausbildet.From the publication DE 10 2009 000 827 A1 a device for connecting two electrical terminals of a pole terminal and a measuring element is known. The two connections are interconnected by means of clinching. In this case, one of the terminals may have an opening into which the other terminal is deformed by means of clinching. It is further described that the opening may have a chamfer, in which the other terminal is pressed by means of clinching, so that forms an undercut.

Die Druckschrift DE 10 2009 000 828 A1 beschreibt eine Vorrichtung zur Befestigung eines Bolzens in einer Polklemme, um einen Polklemmenverbund zu bilden. Mit der Polklemme ist zumindest ein Messelement oder eine Elektronikeinheit verbunden. Hierzu ist ein Isolierkörper vorgesehen, der den Bolzen und die Polklemme elektrisch voneinander isoliert. Der Bolzen ist mit einem isolierenden Material umspritzt, so dass auf diese Weise der Isolierkörper, der aber nicht selbskonsistent bzw. eigenständig ist, gebildet wird. Der Bolzen dient zum Anschluss eines Batteriekabels. In einer anderen Ausführung ist der Bolzen in seinem unteren Bereich mit einer Beschichtung versehen. Der auf diese Weise beschichtete Bolzen wird anschließend in die Polklemme montiert. Die Beschichtung ist nicht unabhängig von dem Bolzen.The publication DE 10 2009 000 828 A1 describes a device for fastening a bolt in a pole terminal to form a Polklemmenverbund. At least one measuring element or an electronic unit is connected to the pole terminal. For this purpose, an insulating body is provided, which electrically isolates the bolt and the pole terminal from each other. The bolt is encapsulated with an insulating material, so that in this way the insulating body, which is not selbstsonsistent or independent, is formed. The bolt is used to connect a battery cable. In another embodiment, the bolt is provided in its lower region with a coating. The coated in this way bolt is then mounted in the pole terminal. The coating is not independent of the bolt.

Offenbarung der ErfindungDisclosure of the invention

Vor diesem Hintergrund werden ein Polklemmenverbund nach Anspruch 1, ein Bolzen gemäß Anspruch 4, ein Verfahren zum Anbringen eines Isolierkörpers an einen Bolzen mit den Merkmalen des Anspruchs 7 und ein Verfahren zum Bestücken einer Polklemme mit einem Bolzen gemäß Anspruch 9 vorgestellt.Against this background, a pole terminal assembly according to claim 1, a bolt according to claim 4, a method for attaching an insulating body to a bolt having the features of claim 7 and a method for assembling a pole terminal with a bolt according to claim 9 are presented.

Ausgestaltungen ergeben sich aus den abhängigen Ansprüchen und der Beschreibung.Embodiments result from the dependent claims and the description.

Bei dem beschriebenen Polklemmenverbund ist der Isolierkörper als selbstkonsistentes bzw. eigenständiges Bauteil ausgebildet. Der Isolierkörper kann in einem mechanischen Fügeprozess, bspw. mittels Verschraubens, Verdrehens, Einpressens, Verpressens usw., mit dem Bolzen verbunden werden. Anschließend ist der Bolzen sicher in dem Isolierkörper fixiert bzw. in diesem positioniert, was die weitere Montage des Bolzens an der Polklemme, um einen Polklemmenverbund zu bilden, erleichtert.In the described Polklemmenverbund the insulating body is designed as a self-consistent or independent component. The insulating body can be connected to the bolt in a mechanical joining process, for example by means of screwing, twisting, press-fitting, pressing, etc. Subsequently, the bolt is securely fixed in the insulating body or positioned in this, which facilitates the further assembly of the bolt on the pole terminal to form a Polklemmenverbund.

Selbstkonsistent bedeutet, dass der Isolierkörper ein eigenständiges Bauteil darstellt, das auch unabhängig vom Bolzen betrachtet und verwendet werden kann und somit nicht, wie bspw. aus dem Stand der Technik bekannt ist, lediglich eine Beschichtung des Bolzens, die bspw. mittels Spritzgießens hergestellt wird, darstellt.Self-consistent means that the insulating body represents an independent component, which can also be considered and used independently of the bolt and thus not, as is known, for example, from the prior art, only a coating of the bolt, which is produced, for example. By injection molding, represents.

Mit der vorgestellten Erfindung wird eine lösbare Verbindung, die verliersicher ausgestaltet sein kann, zwischen einer Polklemme mit Isolierteil und einem Bolzen, der als Gewindebolzen oder Schraubbolzen ausgeführt sein kann, erreicht. Dies hat zur Folge, dass die Zugkräfte von einem Batteriekabel direkt auf den Polklemmenverbund, nämlich Polklemme, Isolierkörper und Bolzen, übertragen werden, ohne einen vorgesehenen Messshunt kurzzuschließen.With the presented invention, a releasable connection that can be configured captive, between a pole terminal with insulating part and a bolt that can be designed as a threaded bolt or bolt, achieved. This has the consequence that the tensile forces of a battery cable directly to the Polklemmenverbund, namely pole terminal, insulator and bolts are transmitted without shorting a designated shunt.

Über diese Verbindung, nämlich die Verbindung zwischen der Polklemme und dem Bolzen, die über den Isolierkörper erfolgt, kann eine mechanische Anbindung an die Polklemme bei gleichzeitiger elektrischen Isolation geschaffen werden. Weiterhin ist zu beachten, dass die Verbindung nicht an die Poklemmenabmessungen gebunden ist.About this connection, namely the connection between the pole terminal and the bolt, which takes place via the insulating body, a mechanical connection to the pole terminal can be created with simultaneous electrical isolation. Furthermore, it should be noted that the connection is not tied to the Poklemmenabmessungen.

Der Bolzen, bspw. ein Gewindebolzen oder Schraubbolzen, kann über den Isolierkörper bzw. das Isolierteil fixiert und in der Polklemme durch Verschrauben oder Verdrehen eingefügt, eingerastet oder verpresst werden. Anstelle eines Gewindes kann auch ein Bajonettverschluss vorgesehen sein. Der Isolierkörper sollte dabei eine ausreichende Flexibilität und Festigkeit besitzen, um das Zusammenfügen der drei Teile zu ermöglichen und ggf. Toleranzen auszugleichen. Über kleine Verrastungen, wie bspw. einen Crashclip bzw. eine Crashrippe, kann sichergestellt werden, dass der Gewindebolzen sicher positioniert ist. Das Material des Isolierkörpers kann ein Kunststoff, wie bspw. ein Elastomer, Duroplast oder Thermoplast, sein. Es sind aber auch andere Materialien denkbar. Die sichere Positionierung des Bolzens erleichtert das spätere Verbinden des Bolzens mit der Polklemme.The bolt, for example, a threaded bolt or bolt, can be fixed on the insulating body or the insulating part and inserted in the terminal post by screwing or twisting, snapped or pressed. Instead of a thread and a bayonet closure may be provided. The insulating body should have sufficient flexibility and strength to allow the joining of the three parts and possibly compensate for tolerances. About small catches, such as. A crash clip or a Crashrip, it can be ensured that the threaded bolt is securely positioned. The material the insulating body may be a plastic, such as, for example, an elastomer, thermoset or thermoplastic. But there are also other materials conceivable. The secure positioning of the bolt facilitates the subsequent connection of the bolt with the pole terminal.

Weitere Vorteile und Ausgestaltungen der Erfindung ergeben sich aus der Beschreibung und den beiliegenden Zeichnungen.Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.

Es versteht sich, dass die voranstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination indicated, but also in other combinations or in isolation, without departing from the scope of the present invention.
