Abstract

The terminal clamp has a main body (4) with a main aperture (3) that fits over the terminal post of the battery and has a slit end (A) that leads to a section that receives a screw (12). - The screw threads into a captive nut located in a recess. The nut has a formed 'V' groove that locates against angled surfaces on the clamp. When the screw is tightened the force on the angled surfaces cause the gap (A) to close and a radial force is applied to the post.

Description

Die Erfindung betrifft eine Anschlußklemme zum lösbaren Befestigen wenigstens eines Stromkabels an einem vorzugsweise zylindrischen oder in axialer Richtung leicht konischen Pol eines Akkumulators oder einer wiederaufladbaren Batterie gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a connecting terminal for the detachable fastening of at least one power cable to a preferably cylindrical or slightly conical pole in the axial direction of an accumulator or a rechargeable battery according to the preamble of patent claim 1.

Derartige Anschlußklemmen sind in unterschiedlichen Konstruktionen und Ausführungsformen bekannt. Beispielsweise aus US-A-1 746 514 oder DE-C-38 11 629 ist es zum Beispiel bei solchen Anschlußklemmen bekannt, daß die Schraube bzw. ihr Schaft oder ihre Mittelachse etwa in der Aufsteckrichtung der Anschlußklemme auf den Pol orientiert ist und beim Anziehen gegenüber dem Gegengewinde oder Gegenstück wenigstens eine Schrägfläche gegen eine analoge und parallele Schrägfläche bewegt und sich beide Schrägflächen bei der Klemmbewegung der Klemmbacken und beim Anziehen der Schraube berühren, so daß die durch die Schraube quer zur Schließrichtung der Klemmbacken bewirkte Axialverstellung und Verminderung des Abstandes an den Schrägflächen in eine Verstellung in Schließrichtung der Klemmbacken umsetzbar ist.Such terminals are known in different designs and embodiments. For example from US-A-1 746 514 or DE-C-38 11 629 it is known, for example in connection terminals of this type, that the screw or its shaft or its central axis is oriented approximately in the direction of attachment of the terminal on the pole and when tightening compared to the counter thread or counterpart at least one inclined surface against an analog and parallel inclined surface and both inclined surfaces touch during the clamping movement of the jaws and when tightening the screw, so that the axial adjustment effected by the screw transversely to the closing direction of the clamping jaws and reduction of the distance on the inclined surfaces can be implemented in an adjustment in the closing direction of the clamping jaws.

Bei solchen Klemmen ist der Anschluß eines Kabels vorgesehen, von welchem dann über entsprechende Abzweigungen verschiedene Verbraucher mit Strom gespeist werden können. Dies kann sich jedoch insbesondere bei dem Anschließen von elektronischen Geräten als nachteilig erweisen.With such terminals, the connection of a cable is provided, from which various consumers can then be supplied with current via corresponding branches. However, this can prove to be disadvantageous in particular when connecting electronic devices.

Es besteht deshalb die Aufgabe, eine Klemmbacke der eingangs erwähnten Art, insbesondere eine solche Klemmbacke, bei welcher die Anzugsbewegung der Schraube über Schrägflächen in eine Verstellung der Klemmbacken in Schließrichtung umsetzbar ist, so auszugestalten, daß wenigstens ein zusätzlicher Kabelanschluß beispielsweise für elektronische Geräte ermöglicht wird.It is therefore an object of the invention to design a jaw of the type mentioned at the outset, in particular such a jaw in which the tightening movement of the screw can be implemented via inclined surfaces in an adjustment of the jaws in the closing direction, so that at least one additional cable connection is made possible, for example, for electronic devices .

Zur Lösung dieser Aufgabe ist die gattungsgemäße Anschlußklemme dadurch gekennzeichnet, daß am Umfang der Klemme an der Seitenfläche ein Vorsprung, Ansatz oder dergleichen für wenigstens einen zusätzlichen Kabelanschluß angeordnet ist.To solve this problem, the generic terminal is characterized in that a projection, extension or the like for at least one additional cable connection is arranged on the circumference of the terminal on the side surface.

Da die Anschlußklemme von der Oberseite her verschlossen oder verklemmt werden kann, also ein entsprechendes Montagewerkzeug die Seiten dieser Anschlußklemme nicht beaufschlagen muß, ergibt sich also die Möglichkeit, an diesen seitlichen Bereichen der Anschlußklemme weitere Kabelanschlüsse vorzusehen. Somit kann der Gebrauchszweck der Anschlußklemme erheblich vergrößert werden. Vor allem ergibt sich dadurch eine weitere Vereinfachung bei dem zusätzlichen Anschließen von Kabeln beispielsweise für elektronische Geräte.Since the connection terminal can be closed or clamped from the top, so that an appropriate assembly tool does not have to act on the sides of this connection terminal, there is thus the possibility of providing further cable connections on these lateral areas of the connection terminal. The purpose of the connection terminal can thus be increased considerably. Above all, this results in a further simplification in the additional connection of cables, for example for electronic devices.

Besonders günstig ist es, wenn der Vorsprung, Ansatz oder zusätzliche Kabelanschluß an wenigstens einer Klemmbacke seitlich von dem Klemmbereich angeordnet ist. Somit wird der Klemmvorgang nicht beeinträchtigt.It is particularly expedient if the projection, extension or additional cable connection is arranged on at least one clamping jaw to the side of the clamping area. Thus, the clamping process is not affected.

Eine weitere Ausgestaltung kann darin bestehen, daß an den seitlichen Bereichen weitere Kabelanschlüsse vorgesehen sind. Dies erlaubt demgemäß das zusätzliche Anschließen weiterer Geräte.A further embodiment can consist in that further cable connections are provided on the lateral areas. Accordingly, this allows additional devices to be connected.

Die Klemmbacken mit den Vorsprüngen oder dergleichen können aus Bundmetall, insbesondere Messing, und die Klemmschraube aus vorzugsweise korrosionsfestem Stahl bestehen. Dies ergibt eine günstige Werkstoffpaarung, die das leichtgängige Verdrehen der Klemmschraube trotz der Reibung einerseits im Gewinde und andererseits am Kopf ermöglicht. Gleichzeitig ist eine solche Anschlußklemme im wesentlichen korrosionsfest, so daß sie auch nach längerer Zeit problemlos wieder gelöst werden kann.The clamping jaws with the projections or the like can be made of collar metal, in particular brass, and the clamping screw can be made of preferably corrosion-resistant steel. This results in a favorable pairing of materials, which enables the screw to be turned easily despite the friction on the one hand in the thread and on the other hand on the head. At the same time, such a connection terminal is essentially corrosion-resistant, so that it can be removed again without problems even after a long period of time.

Dabei kann die Klemmschraube als Imbusschraube ausgebildet sein, so daß das Werkzeug zu ihrer Betätigung möglichst wenig Platz benötigt.The clamping screw can be designed as an Allen screw, so that the tool requires as little space as possible to operate it.

Die Mutter und die Länge des Schaftes der Klemmschraube können derart aufeinander abgestimmt sein, daß auch bei größtmöglicher Verklemmung das Ende der Klemmschraube innerhalb der Mutter liegt. Selbst in Gebrauchsstellung steht somit die Schraube nicht nach unten über und benötigt an dieser Stelle keinen zusätzlichen Platz.The nut and the length of the shaft of the clamping screw can be coordinated with one another in such a way that even with the greatest possible jamming, the end of the clamping screw lies within the nut. Even in the position of use, the screw does not protrude downwards and does not require any additional space at this point.

Vor allem bei Kombination einzelner oder mehrerer der vorbeschriebenen Merkmale und Maßnahmen ergibt sich eine Anschlußklemme für Batteriepole, die, insbeonsondere wenn sie von der Oberseite des Poles her verschlossen werden kann, von der oberen Seite her zugeführt werden kann, an der am wenigsten Behinderungen durch die Anschlußklemme selbst oder die Batterie bestehen. Vor allem wird an den Seitenflächen der Anschlußklemme Platz für weitere Stromanschlußvorsprünge oder dergleichen gewonnen, an denen dann ebenfalls weitere Kabel problemlos angeschlossen werden können, mit denen beispielsweise elektronische Geräte gespeist werden können.Especially when combining one or more of the features and measures described above, there is a connection terminal for battery poles, which, in particular if it can be closed from the top of the pole can be supplied from the top side, where there are the least disabilities due to the connection terminal itself or the battery. Above all, space is gained on the side faces of the connection terminal for further power connection projections or the like, to which further cables can then also be connected without problems, with which, for example, electronic devices can be fed.

Nachstehend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher beschrieben. Die einzige Figur zeigt in schematisierter Darstellung
   einen Querschnitt durch eine Anschlußklemme im Bereich der Verspannung der beiden gegeneinander bewegbaren Klemmbacken, wobei zum Verspannen eine parallel zu einem Batteriepol angeordnete Klemmschraube mit einer etwa U-förmigen Mutter zusammenwirkt, deren konische Schenkel Schrägflächen an beiden Klemmbacken umgreifen, wobei an einer Klemmbacke ein seitlicher Vorsprung für weitere Kabelanschlüsse vorgesehen ist.An embodiment of the invention is described below with reference to the drawing. The only figure shows a schematic representation
a cross section through a terminal in the area of the bracing of the two mutually movable clamping jaws, wherein for clamping a clamping screw arranged parallel to a battery pole interacts with an approximately U-shaped nut, the conical legs of which grip inclined surfaces on both clamping jaws, with a lateral projection on a clamping jaw is provided for further cable connections.

Eine im ganzen mit 1 bezeichnete Anschlußklemme, im folgenden auch kurz Klemme 1 genannt, dient zum lösbaren Befestigen wenigstens eines Stromkabels an einem zylindrischen, in Axialrichtung in der Regel leicht konischen Pol eines Akkumulators bzw. einer Batterie. Der eigentliche Kabelanschluß befindet sich dabei seitlich von der Öffnung, die in Gebrauchsstellung den Pol in sich aufnimmt.A connection terminal, designated as a whole by 1, hereinafter also referred to briefly as terminal 1, is used for the detachable fastening of at least one power cable to a cylindrical, generally slightly conical pole of an accumulator or a battery in the axial direction. The actual cable connection is located on the side of the opening that receives the pole in the position of use.

Diese Öffnung ist jeweils zur Hälfte in zwei den Pol zwischen sich aufnehmende Klemmbacken 4 und 5 so eingearbeitet, daß sie bei geschlossenen Klemmbacken 4 und 5 auch einen im wesentlichen geschlossenen Umriß hat. In Offenstellung kann die Öffnung auf den Pol aufgeschoben und dann mittels einer seitlich des Poles befindlichen Schraube 6 durch Verformen der beiden Klemmbacken 4 und 5 aufeinanderzu an dem Pol angeklemmt werden. Dabei ist vorgesehen, daß die Schraube 6 bzw. ihr Schaft 7 oder ihre Mittelachse etwa in der Aufsteckrichtung der Klemme 1 auf den Pol, also in Gebrauchsstellung etwa parallel zu der Polachse, orientiert ist und beim Anziehen gegenüber einem Gegengewinde 8 in noch zu beschreibender Weise eine Schrägfläche gegen eine Gegenfläche bewegt, so daß die durch die Schraube 6 quer zur Schließrichtung der Klemmbacken 4 und 5 bewirkte Axialverstellung an der Schrägfläche in eine Verstellung in Schließrichtung der Klemmbacken 4 und 5 umgesetzt wird. Dabei weist der das Gegengewinde 8 für die Schraube 6 enthaltende Teil die Schrägfläche 9 auf. Ebenfalls ist vorgesehen, daß das der Schrägfläche 9 jeweils gegenüberliegende Teil eine analoge und parallele Schrägfläche 10 hat und sich beide Schrägflächen 9 und 10 bei der Klemmbewegung der Klemmbacken 4 und 5 und beim Anziehen der Schraube 6 berühren und relativ zueinander verschieben, woraus die gewünschte Klemmbewegung der Klemmbacken 4 und 5 aufeinanderzu und damit die Verengung der Öffnung 3 bewirkt werden.This opening is half worked into two the pole between itself receiving jaws 4 and 5 so that when the jaws 4 and 5 are closed, it also has a substantially closed outline. In the open position, the opening can be pushed onto the pole and then clamped towards the pole by means of a screw 6 located on the side of the pole by deforming the two clamping jaws 4 and 5. It is provided that the screw 6 or its shaft 7 or its central axis is oriented approximately in the plug-on direction of the terminal 1 on the pole, that is to say approximately parallel to the pole axis in the position of use, and when tightened in relation to a counter thread 8 in a manner to be described moves an inclined surface against a counter surface, so that the axial adjustment effected by the screw 6 transversely to the closing direction of the clamping jaws 4 and 5 is converted into an adjustment in the closing direction of the clamping jaws 4 and 5. The part containing the counter thread 8 for the screw 6 has the inclined surface 9. It is also provided that the part opposite the inclined surface 9 has an analog and parallel inclined surface 10 and both inclined surfaces 9 and 10 touch and move relative to one another during the clamping movement of the clamping jaws 4 and 5 and when the screw 6 is tightened, resulting in the desired clamping movement the jaws 4 and 5 towards each other and thus the narrowing of the opening 3 are effected.

Beim Ausführungsbeispiel ist das Gegengewinde 8 für die Klemmschraube 7 in einer Mutter 11 vorgesehen, die dann auch das Teil darstellt, welches der Schrägfläche 10 gegenüberliegt bzw. mit dieser zusammenwirkt.In the exemplary embodiment, the counter thread 8 is provided for the clamping screw 7 in a nut 11, which then also represents the part which lies opposite the inclined surface 10 or cooperates with it.

Man erkennt, daß in dem seitlich des Poles und der Öffnung für den Pol von der Schraube 6 durchsetzten Bereich der Klemmbacken 4 und 5 die beide Klemmbacken 4 und 5 auf der dem Schraubkopf 12 gegenüberliegenden Seite klammerartig und teilweise formschlüssig um- oder übergreifende Mutter 11 vorgesehen ist. Die Klemmschraube 6 verläuft dabei etwa parallel zu dem Pol bzw. zu der Klemmöffnung 3 der Anschlußklemme 1 und ihr Kopf 12 liegt mit seiner Unterseite an quer zur Schließrichtung der Klemmbacken 4 und 5 befindlichen, miteinander fluchtenden, der Mutter 11 gegenüberliegenden Lagerflächen 13 auf. Die in Richtung zu dem Schraubkopf 12 vorstehenden Schenkel 14 der Mutter 11 weisen jeweils die schon erwähnte Schrägfläche 9 auf, die jeweils mit einer Schrägfläche 10 zusammenwirken. Diese Schrägflächen 10 sind dabei an den Unterseiten der Klemmbacken 4 und 5 angeordnet. Der Schaft 7 der Schraube 6 verläuft in Gebrauchsstellung durch in den durch die Klemmbewegung verringerbaren Abstand zwischen den beiden Klemmbacken 4 und 5 außerhalb der Öffung durch dort angeordnete Teilausnehmungen 15 der Klemmbacken parallel oder im wesentlichen parallel zur Mittelachse des Poles und der Klemmöffnung der Klemme 1.It can be seen that in the area of the clamping jaws 4 and 5, through which the screw 6 extends, to the side of the pole and the opening for the pole, the two clamping jaws 4 and 5 on the side opposite the screw head 12 are provided in a clamp-like manner and partially form-fitting nut 11 is. The clamping screw 6 runs approximately parallel to the pole or to the clamping opening 3 of the connecting terminal 1 and its head 12 lies with its underside transverse to the closing direction of the clamping jaws 4 and 5 located, aligned with each other, the nut 11 opposite bearing surfaces 13. The legs 14 of the nut 11 projecting in the direction of the screw head 12 each have the aforementioned inclined surface 9, which each cooperate with an inclined surface 10. These inclined surfaces 10 are arranged on the undersides of the jaws 4 and 5. In the position of use, the shaft 7 of the screw 6 runs parallel or substantially parallel to the central axis of the pole and the clamping opening of the terminal 1 in the distance between the two clamping jaws 4 and 5, which can be reduced by the clamping movement, outside the opening through partial recesses 15 of the clamping jaws arranged there.

Es leuchtet ein, daß beim Anziehen der Schraube 12 gegenüber der Mutter 11 diese mit ihren Schrägflächen 9 stärker gegen die Schrägflächen 10 der Klemmbacken 4 und 5 bewegt und dadurch die Klemmbacken 4 und 5 unter Verringerung oder Beseitigung des Abstandes A gegeneinander verformt werden. Ein in der Klemmöffnung 3 befindlicher Pol wird auf diese Weise eingeklemmt.It is obvious that when the screw 12 is tightened relative to the nut 11, its inclined surfaces 9 move it more strongly against the inclined surfaces 10 of the clamping jaws 4 and 5, thereby deforming the clamping jaws 4 and 5 against each other while reducing or eliminating the distance A. A pole located in the clamping opening 3 is clamped in this way.

Dabei haben die Mutter 11 und die von dieser umgriffenen Bereiche der Klemmbacken 4 und 5 symmetrisch zu der zwischen den beiden Klemmbacken 4 und 5 befindlichen Ebene angeordnete Schrägflächen 9 und 10, so daß beim Anziehen der Schraube 6 eine gleichmäßige Bewegung beider Klemmbacken 4 und 5 aufeinanderzu erfolgt.In this case, the nut 11 and the areas of the jaws 4 and 5 encompassed by this have symmetrical surfaces 9 and 10 arranged symmetrically to the plane located between the two jaws 4 and 5, so that when the screw 6 is tightened a uniform movement of both jaws 4 and 5 towards one another he follows.

Die Lagerflächen 13 für den Kopf 12 der Schraube 6 sind in einer Vertiefung 16 angeordnet und ihr Abstand von der Oberseite kann z.B. der Höhe des Schraubenkopfes 12 entsprechen, ist im Ausführungsbeispiel allerdings etwas geringer. Der Schraubenkopf 12 ist somit ganz oder teilweise in die Klemmbacken 4 und 5 versenkt. Dabei ist es vorteilhaft, wenn die Klemmschraube 6 als Inbusschraube ausgebildet ist, so daß die Vertiefung 16 nur wenig größer als der Schraubenkopf 12 sein muß. Es genügt, wenn in Ausgangsstellung die Vertiefung 16 gegenüber dem Schraubenkopf 12 um die Querbewegungen der Klemmbacken beabstandet ist.The bearing surfaces 13 for the head 12 of the screw 6 are arranged in a recess 16 and their distance from the top can e.g. correspond to the height of the screw head 12, but is somewhat lower in the exemplary embodiment. The screw head 12 is thus completely or partially sunk into the jaws 4 and 5. It is advantageous if the clamping screw 6 is designed as an Allen screw, so that the recess 16 only has to be slightly larger than the screw head 12. It is sufficient if, in the starting position, the recess 16 is spaced apart from the screw head 12 by the transverse movements of the clamping jaws.

In der Figur erkennt man, daß die dem Schraubenkopf 12 abgewandte Unterseite 11a der Mutter 11 zumindest in Klemmstellung etwa bündig mit der benachbarten Unterseite der Klemmbacken 4 und 5 ist, also keinen zusätzlichen Platz benötigt. Dies ist dadurch erreicht, daß die Klemmbacken 4 und 5 im Bereich des Angriffes der Mutter 11 eine entsprechende unterseitige Aussparung haben.In the figure it can be seen that the underside 11a of the nut 11 facing away from the screw head 12 is at least approximately flush with the adjacent underside of the clamping jaws 4 and 5 in the clamping position, that is to say it does not require any additional space. This is achieved in that the jaws 4 and 5 have a corresponding underside recess in the area of the nut 11 attack.

Dabei sind die Dicke der Mutter 11 und die Länge des Schaftes 7 der Klemmschraube 6 derart aufeinander abgestimmt, daß auch bei größtmöglicher Verklemmung das Ende der Klemmschraube 6 innerhalb der Mutter 11 oder allenfalls mit deren Unterseite 11a bündig zu liegen kommt, also nicht daraus hervortritt.The thickness of the nut 11 and the length of the shaft 7 of the clamping screw 6 are coordinated with one another in such a way that even with the greatest possible jamming, the end of the clamping screw 6 comes to lie flush within the nut 11 or at most with its underside 11a, that is to say does not emerge therefrom.

In der Fig. erkennt man, daß aufgrund der vorstehend beschriebenen Anordnung der Klemmschraube 6 und ihrer Betätigung von oben her an wenigstens einer Klemmbacke, z.B. der Klemmbacke 5, seitlich von dem Klemmbereich ein Vorsprung 17, Ansatz oder dergleichen für wenigstens einen zusätzlichen Kabelanschluß angeordnet sein kann, so daß von dieser Klemme 1 auch zusätzliche Kabel zu elektronischen Geräten geführt werden können.In the figure it can be seen that due to the arrangement of the clamping screw 6 described above and its actuation from above on at least one clamping jaw, e.g. the jaw 5, a projection 17, extension or the like can be arranged on the side of the clamping area for at least one additional cable connection, so that additional cables can also be guided to electronic devices from this terminal 1.

Die Klemmbacken 4 und 5 und die Mutter 11 können z.B. aus Buntmetall, insbesondere aus Messing und die Klemmschraube 6 vorzugsweise aus korrosionsfestem Stahl bestehen.The jaws 4 and 5 and the nut 11 can e.g. made of non-ferrous metal, in particular brass and the clamping screw 6 preferably made of corrosion-resistant steel.
