Abstract
Description
Die Erfindung betrifft die Kontaktierung von Batteriepolen. Insbesondere betrifft die Erfindung eine Batterieklemme zur Herstellung eines elektrischen Kontakts zu einem Pol einer Batterie, eine Innenschelle der Batterieklemme und eine Außenschelle der Batterieklemme.The invention relates to the contacting of battery poles. In particular, the invention relates to a battery terminal for making an electrical contact with a pole of a battery, an inner clamp of the battery clamp and an outer clamp of the battery clamp.
Als Batterieklemmen, insbesondere für den Einsatz in Kraftfahrzeugen, werden Schmiedeklemmen aus Gussmetall verwendet. Diese Klemmen sind recht stabil aber verhältnismäßig aufwändig in der Herstellung. Ein weitere Nachteil dieser Klemmen ist ihr hohes Gewicht. Auch können Stanzklemmen aus einem gestanzten Blech verwendet werden. Allerdings weisen diese Klemmen oft eine geringere Verdreh- und Abzugsfestigkeit auf.As battery terminals, in particular for use in motor vehicles, forging clamps made of cast metal are used. These clamps are quite stable but relatively expensive to manufacture. Another disadvantage of these terminals is their high weight. Also punching clamps can be used from a stamped sheet metal. However, these terminals often have a lower torsional and peel strength.
Es ist eine Aufgabe der Erfindung, eine zuverlässige Batterieklemme insbesondere für den Einsatz in Kraftfahrzeugen anzugeben, die sich einfach herstellen lässt.It is an object of the invention to provide a reliable battery terminal, especially for use in motor vehicles, which can be easily manufactured.
Es sind eine Batterieklemme zur Herstellung eines elektrischen Kontakts zu einem Pol einer Batterie, eine Innenschelle für eine solche Batterieklemme und eine Außenschelle für eine solche Batterieklemme gemäß den Merkmalen der unabhängigen Ansprüche angegeben. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.There are a battery terminal for making electrical contact with a pole of a battery, an inner clamp for such a battery terminal and an outer clamp for such a battery terminal according to the features of the independent claims. Further developments of the invention will become apparent from the dependent claims.
Gemäß einem Ausführungsbeispiel der Erfindung ist eine Batterieklemme zur Herstellung eines elektrischen Kontakts zu einem Pol einer Batterie angegeben. Die Batterieklemme weist eine Innenschelle und eine Außenschelle auf. Die Innenschelle ist zur Herstellung eines guten elektrischen Kontakts zu dem Pol der Batterie ausgeführt. Hierfür ist die Innenschelle für die Stromübertragung optimiert. Als Material kommt beispielsweise Messing in Betracht. Auch können andere leitfähige Materialien oder Materiallegierungen verwendet werden.According to one embodiment of the invention, a battery terminal for making an electrical contact to a pole of a battery is indicated. The battery clamp has an inner clamp and an outer clamp. The inner clamp is designed to make good electrical contact with the pole of the battery. For this purpose, the inner clamp is optimized for power transmission. As a material, for example, brass is considered. Also, other conductive materials or material alloys may be used.
Die Außenschelle ist zur Befestigung der Innenschelle an dem Pol der Batterie und insbesondere zur mechanischen Stabilisierung der Innenschelle ausgeführt. Eine der Hauptaufgaben der Außenschelle besteht darin, dafür zu sorgen, dass die Batterieklemme ausreichende mechanische Stabilität aufweist und fest am Batteriepol sitzt. Die Innenschelle ist beispielsweise als Stanzteil, Schmiedeteil, Gussteil oder in Form eines leitenden Kunststoffs ausgeführt.The outer clamp is designed for fastening the inner clamp to the pole of the battery and in particular for the mechanical stabilization of the inner clamp. One of the main tasks of the outer clamp is to ensure that the battery clamp has sufficient mechanical stability and is firmly seated on the battery post. The inner clamp is designed for example as a stamped part, forging, casting or in the form of a conductive plastic.
Die Innenschelle ist als Stanzteil ausgeführt und die Außenschelle weist eine Aufnahmevorrichtung zur Aufnahme einer Befestigungsschraube unter einem Winkel von weniger als 30 Grad zu einer Querachse der Außenschelle auf. Auch kann die Schelle mit Kunststoff-Außenring einen Schraubenwinkel von 34 Grad zu der Querachse der Außenschelle aufweisen.The inner clamp is designed as a stamped part and the outer clamp has a receiving device for receiving a fastening screw at an angle of less than 30 degrees to a transverse axis of the outer clamp. Also, the clamp with plastic outer ring may have a helix angle of 34 degrees to the transverse axis of the outer clamp.
Dies bedeutet, dass die Befestigungsschraube unter einem Winkel von über 60 Grad (unter 60 Grad bei Kunststoffschelle) zur Längsachse der Außenschelle angebracht werden kann.This means that the fixing screw can be mounted at an angle of more than 60 degrees (below 60 degrees with plastic clamp) to the longitudinal axis of the outer clamp.
Innen und Außenschelle werden nur vom Hersteller zusammengebaut. Dies kann durch Einführen, zusammenstecken, umspritzen o.ä. geschehen. Einmal zusammengebaut, kann der Anwender Innen und Außenschelle nicht mehr trennen, sie bilden immer eine Einheit.Inner and outer clamps are only assembled by the manufacturer. This can be by insertion, plug together, overmold or similar. happen. Once assembled, the user can no longer separate the inner and outer clamp, they always form a single unit.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung beträgt der Winkel, den die Befestigungsschraube mit der Querachse der Außenschelle einschließt, maximal 20 Grad und liegt beispielsweise zwischen 16 Grad und 20 Grad. Beispielsweise beträgt der Winkel 18 Grad. Dies nur für die Variante mit Stahlschelle. Die Kunststoff-Variante hat 34 Grad.According to a further embodiment of the invention, the angle which the fastening screw encloses with the transverse axis of the outer clamp is a maximum of 20 degrees and is for example between 16 degrees and 20 degrees. For example, the angle is 18 degrees. This only for the variant with steel clamp. The plastic version has 34 degrees.
Dieser verhältnismäßig kleine Winkel ist vorteilhaft, da er zu einer verbesserten Stabilität der installierten Batterieklemme führt als ein vergleichsweiser großer Winkel von beispielsweise 34 Grad.This relatively small angle is advantageous because it leads to improved stability of the installed battery terminal as a comparatively large angle of for example 34 degrees.
Damit die Befestigungsschraube bzw. deren Mutter problemlos festgezogen werden kann, sind der Schraubenkopf und/oder die Mutter ballig geformt.So that the fastening screw or its nut can be easily tightened, the screw head and / or the nut are crowned.
Hierdurch wird es ermöglicht, dass der Schraubenschlüssel auch unter einem Winkel von beispielsweise 34 Grad zur Querachse der Außenschelle eingreifen kann (hierunter ist gemeint, dass der Schlüssel unter einem Winkel eingreifen kann, der einer Schraubenschrägstellung von 34 Grad entsprechen würde), obgleich die Schraube tatsächlich eine Schrägstellung von unter 30 Grad, beispielsweise 18 Grad, aufweist.This will allow the wrench to engage at an angle of, for example, 34 degrees to the transverse axis of the outer clamp (this is meant to allow the key to engage at an angle that would correspond to a 34 degree helical pitch), although the screw is actually an inclination of less than 30 degrees, for example 18 degrees.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist die Außenschelle als Stanzteil, beispielsweise als einmal gefaltetes Stanz-Biegeteil ausgeführt.According to a further embodiment of the invention, the outer clamp is designed as a stamped part, for example as a once folded stamped and bent part.
Auch kann die Außenschelle (auch Klemmschelle genannt) als Kunststoffbauteil ausgeführt sein.Also, the outer clamp (also called clamp) can be designed as a plastic component.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist die Innenschelle ein Abgangsblech zum Stromtransport von dem Batteriepol zum Verbraucher oder einem weiterführenden Kabel auf. Die Außenschelle weist an deren Oberkante zinnenförmige oder kronenartige Nasen oder Zinnen auf, welche eine genaue Positionierung des Abgangsblechs unter verschiedenen (diskreten) Winkeln ermöglicht. Beispielsweise können drei oder vier solche Zinnen vorgesehen sein, welche eine Positionierung des Abgangsblechs in drei verschiedenen Positionen ermöglicht. Dies wird vom Hersteller montiert, um die Artikelvielfalt zu reduzieren. Der Anwender nimmt diese Positionierung im Allgemeinen nicht selber vor.According to a further exemplary embodiment of the invention, the inner clamp has a discharge plate for carrying electricity from the battery pole to the load or a continuing cable. The outer clamp has at the upper edge crenellated or crown-like noses or pinnacles, which allows accurate positioning of the outlet sheet at different (discrete) angles. For example, three or four such battlements may be provided which allow positioning of the departure plate in three different positions. This is assembled by the manufacturer to reduce the variety of items. The user does not generally do this positioning himself.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist die Außenschelle oder die Innenschelle mehrere Rastnasen auf, die zur Fixierung oder Abstützung der Außenschelle an der Innenschelle ausgeführt sind. Beispielsweise weist die Innenschelle entsprechende Gegenstücke auf, in welche die Rastnasen eingreifen können. Siehe dazu
Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist die Innenschelle zwei Laschen auf, die zur Aufnahme der Befestigungsschraube ausgeführt sind.According to a further embodiment of the invention, the inner clamp has two tabs, which are designed to receive the fastening screw.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist die Außenschelle zwei Laschen auf, die zur Aufnahme der Befestigungsschraube ausgeführt sind. Im installierten Zustand sind dann diese beiden Laschen der Außenschelle zwischen den Laschen der Innenschelle angeordnet.According to a further embodiment of the invention, the outer clamp has two tabs, which are designed to receive the fastening screw. In the installed state these two tabs of the outer clamp between the tabs of the inner clamp are then arranged.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist die Innenschelle an deren Innenseite (also im zylindrischen oder konischen Bereich, je nach Form des Batteriepols) zwei Ringzonen auf, zwischen denen sich eine Freifläche befindet. Hierdurch kann ein Quetschen (Verformen) des Bleipols der Batterie, der im mittleren Bereich hohl sein kann, vermieden werden.According to a further embodiment of the invention, the inner clamp on the inside (ie in the cylindrical or conical region, depending on the shape of the battery pole) on two ring zones, between which there is an open space. This can be a squashing (deformation) of the lead pole of the battery, which may be hollow in the central region, can be avoided.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist die Innenschelle an einer Seite eine Führungsnase auf, die beim Zusammenbiegen der Innenschelle in eine entsprechende Aussparung an einer zweiten Seite der Innenschelle eingreift. Auf diese Weise kann beispielsweise vermieden werden, dass die Innenschelle verkantet.According to a further exemplary embodiment of the invention, the inner clamp has on one side a guide nose, which, when the inner clamp is bent together, engages in a corresponding recess on a second side of the inner clamp. In this way, it can be avoided, for example, that the inner clamp is tilted.

Klemmung und Zusatzfunktionen werden über die darüber geschobene Außenschelle (beispielsweise eine Kunststoffschelle) bereitgestellt.At this point it should be pointed out again that the contact or
Die Kontaktschelle 101 weist eine einfache aber sehr stabile Ausführung der Verschraublaschen 3502, 3503 auf. Die Verschraublaschen sind im Schraubenbereich kreisbogenförmig ausgebildet, um die Schraube besser zu umgreifen und die stirnseitige Kontaktfläche an den Verschraublaschen zu vergrößern. Dies bewirkt eine optimierte Kraftübertragung vom Schraubenkopf bzw. der Mutter zur Schelle hin. Durch die Zick-Zack-Schlitzung der Schelle und die Schrägverschraubung wird ein zusätzliches Festkrallen am Batteriepol erreicht und bewirkt somit höchste Verdrehmomente. Gegenüber massiven Metallschellen besteht eine deutliche Gewichtseinsparung.The
Bei Kunststoffausführung der Außenschelle 102 ist das abgewinkelte Element 3305 ebenfalls in Kunststoff ausgeführt und dient dem Schutz und der Stabilisierung des Abgangsbleches 105 der Innenschelle 101. An dieser Stelle ist zu beachten, dass insbesondere auch die Endstücke 3302 der Batterieklemmen der
Auch können Plus- und Minus-Pol durch Färbung der Entsprechenden Batterieklemme farblich gekennzeichnet sein (schwarz bzw. rot).Also, plus and minus pole can be color-coded by coloring the corresponding battery terminal (black or red).
