Definitions
- the invention relates to a battery terminal according to the preamble of claim 1.
- Such Batteriepolan gleichklemmen are for example from the German patent application DE 30 29 335 known.
- a through hole is provided laterally on the jaws.
- the screw is screwed with a locknut and the lever pivots around the screw on a cam piece.
- To close the lever is pivoted about the screw axis so that it presses the cams of the cam piece in the direction of the jaws.
- a jamming of the pole is effected in the jaws.
- the disadvantage of this solution is that the design of the cam is decisive for the clamping force of the jaws.
- a secure connection of the terminal with the battery post during assembly can not be guaranteed. Jamming is made possible only after assembly, in which the lever is pivoted. Thus, no reliable statements about the reliability of the deadlock after assembly can be made.
- the lever is pivotally mounted on an additional rotary axis element.
- the rotary axis element is designed so that it is arranged perpendicular to the axis of the closure element.
- the axis of rotation element may be a bolt which has a bore extending transversely to its longitudinal axis into which the closure element is inserted.
- a lever is pivotably arranged around the rotary axis element, so that the pivot plane of the lever lies substantially parallel to the axis of the closure element.
- the lever can be in the use position, ie the lever is in the position in which the terminal is closed.
- the closure element and the counterpart is moved towards each other for assembly, wherein between the closure element and the counterpart, the rotary axis element is arranged and the Auffactzutouch of the closure element and the counterpart causes a jamming of the lever with the jaws.
- the force can be determined with which the lever compresses the jaws.
- the force with which the jaws are clamped to the pole can already be determined for mounting. This leads to a defined assembly condition that is suitable for quality assurance purposes.
- the closure element is a screw and the counterpart is a mating thread or a lock nut.
- the screw is screwed to the counterpart or the locknut when closing.
- the pole connecting terminal can be mounted in a particularly simple manner by the rotational axis element and the lever being detachably arranged on the clamping body.
- the rotary axis element can be designed so that the closure element is inserted through a bore.
- the lever has two cam-shaped bearing parts, each having holes into which the rotary axis element is inserted.
- the bores are preferably eccentric to a center of the bearing parts, so that the bearing parts form cams.
- the bearing parts are fixed by means of the plugged by the rotary axis element closure element on the rotary axis element.
- the jaws have flange portions which receive the closure element.
- the flange portions may be outwardly extending extensions of the jaws.
- the flange portions are preferably formed so that they receive the closure element and form a contact surface for the lever, so that the lever together with the closure element, the flange can move toward each other, whereby the jaws are closed.
- the screw or the lock nut are easily accessible. Preference is given to the use of a square screw, which bears against a flange area. To screw the nut is then bolted to the screw. By using a spacer sleeve, a sufficiently large distance between the lock nut and the rotary axis element can be ensured, so that the nut can be easily screwed with a tool.
- the flange areas have oppositely directed inclined surfaces. In these inclined surfaces engage counter surfaces of the closure element or the counterpart.
- the inclined surfaces on the flange portions and the mating surfaces are complementarily curved in shape, wherein both curvatures are in the same direction and correspond approximately. This ensures that when tightening the counterpart, the closure element fits tightly against the flange and a canting is connected.
- the lever has at least one cam-shaped bearing part.
- This cam-shaped bearing part has at least two legs, which have different distances to the axis of rotation of the lever.
- a first side, or a first leg has a short distance to the pivot axis, whereas a second side, or a second leg has a long distance to the pivot axis.
- the flange parts are inclined at about 45 ° relative to the pole axis.
- the lever arm can then lie in the position of use perpendicular to the polar axis. This means that access from above the pole is easily possible by pulling the lever upwards, whereby the first side is pivoted in the direction of the flange areas and the connection terminal is opened.
- Fig. 1 shows an exploded view with a lever 2, a rotary axis member 4, a lock nut 6 and a spacer sleeve 8.
- the lever 2 has two cam-shaped bearing parts 10 a, b, which are integrally formed with a lever arm 12.
- the bearing parts 10a, 10b concentric bores are arranged, in which the rotary axis element 4 can be accommodated.
- the holes are designed so that a first leg 14 and a second leg 16 forms on the cam-shaped bearing parts 10, wherein the distances of the legs 14 and 16 are different to the center of the bore.

- the Drehachselement 47 has a bore 18 into which a screw (not shown) can be inserted.
- the rotary axis element 4 is milled in the region of the bore 18, so that a support surface for the spacer sleeve 8 is formed.
- Fig. 2 shows a further exploded view of an arrangement according to the invention.
- Fig. 2 shows a clamping body 20 with jaws 22 and integrally formed thereon flange 24.
- a square screw 26 is also shown.
- the square screw 26 is inserted into concentric holes in the flange 24.
- the rotary axis element 4 is inserted into the holes in the bearing parts 10. Then, the square screw 26 is pushed through the bore 18, whereby the lever 2 is fixed to the rotation axis member 4. Finally, the screw 26 is pushed through the spacer sleeve 8 and screwed to the lock nut 6.
- FIG. 3 A screw connection of the terminal is shown in Fig. 3.
- the terminal 1 is mounted on a battery (not shown).
- the lever arm 12 is perpendicular to the axis of the battery post and the second side 16 abuts against the flange portion 24b.
- the sleeve 8 is pressed against the rotary axis element 4. This results in a force F parallel to the axis of the screw 26.
- the flange portions 24 are moved towards each other.
- the clamping jaws 22 of the clamping body 20 are moved towards each other, so that a pole between the jaws can be jammed.
- a predetermined torque can be applied, so that the force F can be determined with which the lever 2 and the screw 26, the flange portions 24 compress. Knowing the force F can be determined, with which force the jaws 22 jam the pole. This allows accurate quality control of the connection of the clamp body 20 to the pole.
- an electrical connection for a battery cable which is electrically contacted by means of the terminal according to the invention at the pole.
- FIG. 4 shows a connection terminal according to the invention in an open position.
- the lever 2 is now pivoted about the rotary axis element 4 in such a way that, instead of the second side 16, the first side 14 points in the direction of the flange region 24.
- the distance between the pivot axis element 4 and the first side 14 is considerably shorter than the distance between the pivot axis element 4 and the second side 16. This results in a pivoting of the lever 2 in the position shown in Fig. 4, a free running of the flange portions 24 so that they are no longer pressed together.
- the jaws 22, which are preferably formed from forged material, are now in an open position and the terminal 1 can be readily removed from the pole (not shown). The position shown in Fig.
- the terminal according to the invention is fixed in the position of the lever shown in Fig. 3 to the pole.
- the mating surfaces 28 engage in the inclined surfaces of the flange portion 24a.
- the curvature of the inclined surfaces prevents the screw 26 from tilting against the flange region 24. This ensures a secure screwing. This means that the force F, with which the flange portions 24 are pressed against each other, can be kept constant even during operation.
- the counter nut is designed to be self-locking, so that a loosening of the lock nut 6 can be prevented by the screw 26.
- the terminal By the terminal according to the invention, it is possible to screw the jaws with a tool with a suitable torque on the battery pole.

Abstract
Description
Die Erfindung betrifft einen Batteriepolanschlussklemme ach dem Oberbegriff des Anspruchs 1.The invention relates to a battery terminal according to the preamble of
Derartige Batteriepolanschlussklemmen sind beispielsweise aus der
Aus der
Aus den zuvor aufgezeigten Nachteilen ergibt sich die erfindungsgemäße Aufgabe, eine Batteriepolanschlussklemme der eingangs genannten Art derart weiter zu entwickeln, dass vorgegebene Montagebedingungen erfüllt werden können. Ferner soll eine Batteriepolanschlussklemme zur Verfügung gestellt werden, die hohe Qualitätsanforderungen an die Montagegenauigkeit erfüllt. Ein kontrollierbarer Montageprozess soll durch eine erfindungsgemäße Batteriepolanschlussklemme gewährleistet werden.From the above-mentioned disadvantages results in the object of the invention to further develop a Batteriepolanschlussklemme of the type mentioned in that predetermined installation conditions can be met. In addition, a battery pole terminal is to be provided, which meets high quality requirements for mounting accuracy. A controllable assembly process should be ensured by a Be ensured battery terminal according to the invention.
Diese Aufgabe wird erfindungsgemäß durch eine Batteriepolanschlussklemme nach Anspruch 1 gelöst.This object is achieved by a Batteriepolanschlussklemme according to
Gemäß dieser Lösung wird der Hebel an einem zusätzlichen Drehachsenelement schwenkbar angeordnet. Das Drehachsenelement ist so gestaltet, dass es senkrecht zur Achse des Verschlusselements angeordnet ist. Das Drehachsenelement kann ein Bolzen sein, der eine quer zu seiner Längsachse verlaufende Bohrung aufweist, in welche das Verschlusselement eingesteckt ist. Um das Drehachsenelement ist ein Hebel schwenkbar angeordnet, so dass die Schwenkebene des Hebels im Wesentlichen parallel zur Achse des Verschlusselements liegt. Für die Montage kann der Hebel in der Gebrauchsstellung sein, d. h. der Hebel ist in der Position, in der die Anschlussklemme geschlossen ist. Dann wird zur Montage das Verschlusselement und das Gegenstück aufeinander zu bewegt, wobei zwischen dem Verschlusselement und dem Gegenstück das Drehachsenelement angeordnet ist und die Aufeinanderzubewegung des Verschlusselements und des Gegenstücks eine Verklemmung des Hebels mit den Klemmbacken bewirkt. Durch eine definierte Kraft mit der das Verschlusselement und das Gegenstück aufeinander zu verstellbar ist, lässt sich die Kraft bestimmen, mit der der Hebel die Klemmbacken zusammendrückt. Dadurch kann bereits zur Montage die Kraft bestimmt werden, mit welcher die Klemmbacken an dem Pol angeklemmt sind. Das führt zu einer definierten Montagebedingung, die zu Qualitätssicherungszwecken geeignet ist.According to this solution, the lever is pivotally mounted on an additional rotary axis element. The rotary axis element is designed so that it is arranged perpendicular to the axis of the closure element. The axis of rotation element may be a bolt which has a bore extending transversely to its longitudinal axis into which the closure element is inserted. A lever is pivotably arranged around the rotary axis element, so that the pivot plane of the lever lies substantially parallel to the axis of the closure element. For assembly, the lever can be in the use position, ie the lever is in the position in which the terminal is closed. Then, the closure element and the counterpart is moved towards each other for assembly, wherein between the closure element and the counterpart, the rotary axis element is arranged and the Aufeinanderzubewegung of the closure element and the counterpart causes a jamming of the lever with the jaws. By a defined force with which the closure element and the counterpart to each other is adjustable, the force can be determined with which the lever compresses the jaws. As a result, the force with which the jaws are clamped to the pole can already be determined for mounting. This leads to a defined assembly condition that is suitable for quality assurance purposes.
Es wird auch vorgeschlagen, dass das Verschlusselement eine Schraube und das Gegenstück ein Gegengewinde oder eine Gegenmutter ist. In diesem Fall wird beim Verschließen die Schraube mit dem Gegenstück oder der Gegenmutter verschraubt. Beim Verschrauben bewegt sich die Mutter in Richtung des Schraubenkopfes und drückt dabei das Drehachsenelement und den Hebel in Richtung der Klemmbacken, die dadurch aufeinander zu bewegt werden.It is also proposed that the closure element is a screw and the counterpart is a mating thread or a lock nut. In this case, the screw is screwed to the counterpart or the locknut when closing. When screwing the nut moves in the direction of the screw head, thereby pressing the pivot element and the lever in the direction of the jaws, which are thereby moved towards each other.
Beim Verschrauben kann ein bekanntes, vorherbestimmbares Drehmoment angewendet werden, so dass die Montagebedingungen definierbar sind.When screwing a known, predictable torque can be applied so that the mounting conditions are definable.
Besonders einfach lässt sich die Polanschlussklemme montieren, indem das Drehachsenelement und der Hebel lösbar an dem Klemmkörper angeordnet sind. Insbesondere kann das Drehachsenelement so gestaltet sein, dass das Verschlusselement durch eine Bohrung gesteckt ist. Der Hebel weist zwei nockenförmige Lagerteile auf, die jeweils Bohrungen aufweisen, in die das Drehachsenelement gesteckt ist. Die Bohrungen sind vorzugsweise exzentrisch zu einem Mittelpunkt der Lagerteile, so dass die Lagerteile Nocken ausbilden. Die Lagerteile sind mittels dem durch das Drehachsenelement gesteckte Verschlusselement an dem Drehachsenelement fixiert. Beim Verschrauben wird das Drehachsenelement zusammen mit dem Hebel in Richtung der Klemmbacken bewegt, wodurch ein Verklemmen der Klemmbacken an dem Pol bewirkt wird.The pole connecting terminal can be mounted in a particularly simple manner by the rotational axis element and the lever being detachably arranged on the clamping body. In particular, the rotary axis element can be designed so that the closure element is inserted through a bore. The lever has two cam-shaped bearing parts, each having holes into which the rotary axis element is inserted. The bores are preferably eccentric to a center of the bearing parts, so that the bearing parts form cams. The bearing parts are fixed by means of the plugged by the rotary axis element closure element on the rotary axis element. When screwing the rotary shaft member is moved together with the lever in the direction of the jaws, whereby a jamming of the jaws is effected on the pole.
Vorteilhaft ist, wenn die Klemmbacken Flanschbereiche aufweisen, die das Verschlusselement aufnehmen. Die Flanschbereiche können nach außen ragende Verlängerungen der Klemmbacken sein. Die Flanschbereiche sind bevorzugt so gebildet, dass sie das Verschlusselement aufnehmen und eine Anlagefläche für den Hebel bilden, so dass der Hebel zusammen mit dem Verschlusselement die Flanschbereiche aufeinander zu bewegen kann, wodurch die Klemmbacken verschlossen werden.It is advantageous if the jaws have flange portions which receive the closure element. The flange portions may be outwardly extending extensions of the jaws. The flange portions are preferably formed so that they receive the closure element and form a contact surface for the lever, so that the lever together with the closure element, the flange can move toward each other, whereby the jaws are closed.
Um eine Montage mittels eines Werkzeuges zu erleichtern ist es vorteilhaft, wenn die Schraube oder die Gegenmutter leicht zugänglich sind. Bevorzugt ist die Verwendung einer Vierkantschraube, die an einem Flanschbereich anliegt. Zum Verschrauben wird dann die Mutter gegenüber der Schraube verschraubt. Durch die Verwendung einer Abstandshülse kann ein genügend großer Abstand zwischen Gegenmutter und Drehachsenelement gewährleistet werden, so dass die Mutter leicht mit einem Werkzeug verschraubt werden kann.To facilitate assembly by means of a tool, it is advantageous if the screw or the lock nut are easily accessible. Preference is given to the use of a square screw, which bears against a flange area. To screw the nut is then bolted to the screw. By using a spacer sleeve, a sufficiently large distance between the lock nut and the rotary axis element can be ensured, so that the nut can be easily screwed with a tool.
Vorteilhaft ist, wenn beim Anziehen des Verschlusselements gegenüber dem Gegenstück sich wenigstens eine Schrägfläche gegen eine Gegenfläche bewegt, so dass die durch das Verschlusselement quer zur Schließrichtung der Klemmbacke bewirkte Axialverstellung an der Schrägfläche in eine Verstellung in Schließrichtung der Klemmbacken umsetzbar ist. Dazu ist vorgesehen, dass die Flanschbereiche gegeneinander gerichtete Schrägflächen aufweisen. In diese Schrägflächen greifen Gegenflächen des Verschlusselements oder des Gegenstücks ein. Die Schrägflächen an den Flanschbereichen und die Gegenflächen sind komplementär gekrümmt geformt, wobei beide Krümmungen gleichsinnig sind und sich in etwa entsprechen. Hierdurch wird erreicht, dass beim Anziehen des Gegenstücks das Verschlusselement eng an den Flanschbereichen anliegt und eine Verkantung verbindet wird.It is advantageous if when tightening the closure element relative to the counterpart moves at least one inclined surface against a counter surface, so that the effected by the closure element transversely to the closing direction of the jaw axial displacement on the inclined surface in an adjustment in the closing direction of the jaws can be implemented. For this purpose, it is provided that the flange areas have oppositely directed inclined surfaces. In these inclined surfaces engage counter surfaces of the closure element or the counterpart. The inclined surfaces on the flange portions and the mating surfaces are complementarily curved in shape, wherein both curvatures are in the same direction and correspond approximately. This ensures that when tightening the counterpart, the closure element fits tightly against the flange and a canting is connected.
Um eine manuelle Demontage und Re-montage der Batteriepolanschlussklemme zu ermöglichen, wird vorgeschlagen, dass der Hebel zumindest ein nockenförmiges Lagerteil aufweist. Dieses nockenförmige Lagerteil hat zumindest zwei Schenkel, wobei diese unterschiedliche Abstände zur Drehachse des Hebels haben. Eine erste Seite, bzw. ein erster Schenkel hat einen kurzen Abstand zur Schwenkachse, wogegen eine zweite Seite, bzw. ein zweiter Schenkel einen langen Abstand zur Schwenkachse hat. Wird nun der Hebel um die Schwenkachse verschwenkt, ergeben sich unterschiedliche Abstände zwischen Außenkante der Schenkel und der Drehachse. Dadurch kann der Hebel in der Gebrauchstellung unmittelbar an den Klemmbacken, bzw. den Flanschbereichen anliegen und die Klemmbacken an dem Pol verklemmen, wogegen beim Öffnen des Hebels die erste Seite in Richtung der Flanschbereiche, bzw. der Klemmbacken zeigt, so dass eine oder nur noch eine geringe Kraft auf die Klemmbacken, bzw. die Flanschbereiche ausgeübt wird. In diesem Fall ist der Pol nicht mehr mit den Klemmbacken verklemmt.In order to enable manual disassembly and re-assembly of the battery pole terminal, it is proposed that the lever has at least one cam-shaped bearing part. This cam-shaped bearing part has at least two legs, which have different distances to the axis of rotation of the lever. A first side, or a first leg has a short distance to the pivot axis, whereas a second side, or a second leg has a long distance to the pivot axis. Now, if the lever is pivoted about the pivot axis, there are different distances between the outer edge of the legs and the axis of rotation. This allows the lever in the use position directly against the jaws, and the flange and clamp the jaws on the pole, whereas when you open the lever, the first page in the direction of the flange, or the jaws shows, so that one or only a small force on the jaws, or the flange is exercised. In this case, the pole is no longer jammed with the jaws.
Um einen geringen Bauraum zu erreichen und einen leichten Zugang zum Hebelarm zu ermöglichen, wird vorgeschlagen, dass die Flanschteile in etwa 45° gegenüber der Polachse geneigt sind. In diesem Fall kann der Hebelarm dann in der Gebrauchsstellung senkrecht zur Polachse liegen. Das bedeutet, dass ein Zugriff von oberhalb des Pols einfach möglich ist, indem der Hebel nach oben gezogen wird, wodurch die erste Seite in Richtung der Flanschbereiche verschwenkt wird und die Anschlussklemme geöffnet wird.In order to achieve a small space and to allow easy access to the lever arm, it is proposed that the flange parts are inclined at about 45 ° relative to the pole axis. In this case, the lever arm can then lie in the position of use perpendicular to the polar axis. This means that access from above the pole is easily possible by pulling the lever upwards, whereby the first side is pivoted in the direction of the flange areas and the connection terminal is opened.

Fig. 1 zeigt eine Explosionszeichnung mit einem Hebel 2, einem Drehachsenelement 4, einer Gegenmutter 6 und einer Abstandshülse 8. Der Hebel 2 weist zwei nockenförmige Lagerteile 10a, b auf, die einstückig mit einem Hebelarm 12 gebildet sind. In den Lagerteilen 10a, 10b sind konzentrische Bohrungen angeordnet, in die das Drehachsenelement 4 aufnehmbar ist. Die Bohrungen sind so gestaltet, dass sich an den nockenförmigen Lagerteilen 10 ein erster Schenkel 14 und ein zweiter Schenkel 16 bildet, wobei die Abstände der Schenkel 14 und 16 zum Mittelpunkt der Bohrung unterschiedlich sind. Der Schenkel 14 bildet eine erste Seite, die einen kurzen Abstand zu dem Drehachsenelement 4 hat und der Schenkel 16 bildet eine zweite Seite, die einen langen Abstand zu dem Drehachsenelement 4 hat.Fig. 1 shows an exploded view with a
Das Drehachselement 47 weist eine Bohrung 18 auf, in die eine Schraube (nicht gezeigt) einsteckbar ist. Das Drehachsenelement 4 ist im Bereich der Bohrung 18 überfräst, so dass eine Auflagefläche für die Abstandshülse 8 gebildet ist.The Drehachselement 47 has a
Fig. 2 zeigt eine weitere Explosionszeichnung einer erfindungsgemäßen Anordnung. Neben den in Fig. 1 dargestellten Elementen zeigt Fig. 2 einen Klemmkörper 20 mit Klemmbacken 22 und einstückig daran gebildeten Flanschbereichen 24. Außerdem dargestellt ist eine Vierkantschraube 26. Zur Montage wird die Vierkantschraube 26 in konzentrische Bohrungen in den Flanschbereichen 24 gesteckt. Außerdem wird das Drehachsenelement 4 in die Bohrungen in den Lagerteilen 10 gesteckt. Daraufhin wird die Vierkantschraube 26 durch die Bohrung 18 hindurchgeschoben, wodurch der Hebel 2 an dem Drehachsenelement 4 fixiert ist. Schließlich wird die Schraube 26 durch die Abstandshülse 8 geschoben und mit der Gegenmutter 6 verschraubt.Fig. 2 shows a further exploded view of an arrangement according to the invention. In addition to the elements shown in Fig. 1, Fig. 2 shows a clamping
Eine Verschraubung der Anschlussklemme ist in Fig. 3 gezeigt. In der in Fig. 3 dargestellten Darstellung wird die Anschlussklemme 1 auf einen Batteriepol (nicht dargestellt) montiert. Der Hebelarm 12 ist senkrecht zur Achse des Batteriepols und die zweite Seite 16 liegt an dem Flanschbereich 24b an. Beim Verschrauben der Gegenmutter 6 mit der Schraube 26 wird die Hülse 8 gegen das Drehachsenelement 4 gedrückt. Hierdurch ergibt sich eine Kraft F parallel zur Achse der Schraube 26. Die Flanschbereiche 24 werden aufeinander zu bewegt. Dadurch werden die Klemmbacken 22 des Klemmkörpers 20 aufeinander zu bewegt, so dass ein Pol zwischen den Klemmbacken verklemmt werden kann. Beim Anziehen der Schraube 6 kann ein vorbestimmtes Drehmoment angewendet werden, so dass die Kraft F bestimmbar ist, mit der der Hebel 2 und die Schraube 26 die Flanschbereiche 24 zusammendrücken. In Kenntnis der Kraft F kann bestimmt werden, mit welcher Kraft die Klemmbacken 22 den Pol verklemmen. Dies erlaubt eine genaue Qualitätskontrolle des Anschlusses des Klemmkörpers 20 an dem Pol. Nicht dargestellt ist ein elektrischer Anschluss für ein Batteriekabel, welches mit Hilfe der erfindungsgemäßen Anschlussklemme an dem Pol elektrisch kontaktiert wird.A screw connection of the terminal is shown in Fig. 3. In the illustration shown in Fig. 3, the
Fig. 4 zeigt eine erfindungsgemäße Anschlussklemme in einer Offenposition. Im Gegensatz zu der in Fig. 3 gezeigten Gebrauchsstellung ist der Hebel 2 nun derart um das Drehachsenelement 4 geschwenkt, dass anstatt der zweiten Seite 16 die erste Seite 14 in Richtung des Flanschbereichs 24 zeigt. Wie dargestellt, ist der Abstand zwischen Drehachsenelement 4 und erster Seite 14 erheblich kürzer als der Abstand zwischen Drehachsenelement 4 und zweiter Seite 16. Dadurch ergibt sich bei einem Verschwenken des Hebels 2 in die in Fig. 4 gezeigte Position ein Freilaufen der Flanschbereiche 24, so dass diese nicht mehr aufeinander zu gedrückt sind. Die Klemmbacken 22, die bevorzugt aus geschmiedetem Material gebildet sind, befinden sich nun in einer offenen Position und die Anschlussklemme 1 kann ohne weiteres von dem Pol (nicht gezeigt) entfernt werden. Die in Fig. 4 gezeigte Position dient zur Demontage bzw. zur manuellen Re-montage. Um jedoch eine verlässliche Aussage über die Qualität der Montage der Anschlussklemme an dem Pol treffen zu können, wird die erfindungsgemäße Anschlussklemme in der in Fig. 3 gezeigten Position des Hebels an dem Pol befestigt.4 shows a connection terminal according to the invention in an open position. In contrast to the position of use shown in FIG. 3, the
Bei dem Verschrauben der Schraube 26 mit der Gegenmutter 6 muss verhindert werden, dass die Schraube 26 sich an dem Flanschbereich 24a verkantet. In diesem Falle könnte es dazu kommen, dass durch die Verkantung das maximal zulässige Drehmoment an der Schraube 26 erreicht wird, ohne dass die Flanschbereiche 24 genügend weit aufeinander zu bewegt worden sind. Im Betrieb kann es dann dazu kommen, dass die Verkantung der Schraube 26 an dem Flanschbereich 24a aufgelöst wird. Dann löst sich die Verbindung und ein sicherer Halt der Klemmbacken 22 an dem Pol kann nicht mehr gewährleistet sein. Aus diesem Grunde wird außerdem vorgeschlagen, dass an der Schraube 26 Gegenflächen 28 gebildet sind. Diese komplementär gekrümmt geformten Gegenflächen 28 entsprechen in dem Flanschbereich 24a vorgesehenen, gegeneinander gerichteten Schrägflächen (nicht gezeigt). Beim Verschrauben der Schraube 26 mit der Gegenmutter 6 greifen die Gegenflächen 28 in die Schrägflächen des Flanschbereichs 24a. Durch die Krümmung der Schrägflächen wird verhindert, dass sich die Schraube 26 an dem Flanschbereich 24 verkantet. Hierdurch wird eine sichere Verschraubung gewährleistet. Das bedeutet, dass die Kraft F, mit der die Flanschbereiche 24 gegeneinander gedrückt werden, auch in Betriebszeiten konstant gehalten werden kann. Bevorzugt ist, dass die Gegenmutter selbstsichernd ausgeführt ist, so dass ein Lösen der Gegenmutter 6 von der Schraube 26 verhindert werden kann.When screwing the
Durch die erfindungsgemäße Klemme ist es möglich, die Klemmbacken mit einem Werkzeug mit geeignetem Drehmoment auf dem Batteriepol zu verschrauben. Der Schnellspannmechanismus mittels des Hebels ermöglicht eine einfache, manuelle Demontage und Re-montage. Durch das Montieren in der Gebrauchsstellung, d.h. in der geschlossenen Position des Hebels kann die Gegenmutter mit einem bekannten Drehmoment angezogen werden, wodurch ein Verklemmen der Klemmbacken mit dem Pol stets mit gleicher Kraft gewährleistet ist. Erfindungsgemäß ist ein Verschraubprozess mit Werkzeug möglich, wobei beim Schraubprozess eine Drehmomentüberwachung eingerichtet werden kann. Die Demontage ist werkzeuglos möglich.By the terminal according to the invention, it is possible to screw the jaws with a tool with a suitable torque on the battery pole. The quick-release mechanism by means of the lever allows easy, manual disassembly and re-assembly. By mounting in the position of use, ie in the closed position of the lever, the lock nut can be tightened with a known torque, whereby a jamming of the jaws is always ensured with the pole with the same force. According to the invention, a screwing process with a tool is possible, wherein a torque monitoring can be set up during the screwing process. Dismantling is possible without tools.
