The lever is reciprocally movable tangentially to the drum by operating the handles (6,7) of the pliers so that the drum turns with the bolt engaged in the slot. The slot widens to an open side and has a larger closed dimension than the bolt diameter in the expanded region, which is opposite the bolt in a rest position.

Description

Die vorliegende Erfindung betrifft eine Zange mit einer Crimpstation zum Aufcrimpen einer Aderendhülse auf ein isoliertes Ende eines elektrischen Leiters, mit einer Crimptrommel, welches innerhalb eines Zangengehäuses um eine Achse drehbar sowie längs dieser Achse aus einer Ruheposition in eine Arbeitsposition verschiebbar und an einem stimseitigen Ende mit mindestens einem Trommelbolzen versehen ist, welcher bei in Arbeitsposition verschobener Crimptrommel in einen Schlitz eines plattenförmigen Transporthebel eingreift, wobei der Transporthebel durch Betätigung der Handgriffe der Zange tangential zur Crimptrommel vor- und zurückbewegbar ist, so daß bei in den Schlitz des Transporthebels eingreifendem Trommelbolzen eine Drehbewegung der Crimptrommel erfolgt.The present invention relates to a pair of pliers with a crimping station for Crimping a wire end ferrule onto an insulated end of an electrical conductor, with a crimping drum, which within a pliers housing about an axis rotatable and along this axis from a rest position to a working position slidable and at one end with at least one Drum bolt is provided, which shifted in working position Crimping drum engages in a slot of a plate-shaped transport lever, wherein the transport lever tangential by operation of the pliers handles the crimping drum is moved back and forth, so that when in the slot of the Transport lever engaging drum bolt a rotational movement of the Crimping drum is done.

Eine Zange mit einer Crimpstation der gattungsgemäßen Art ist in der EP 0 562 229 B1 ausführlich beschrieben, insbesondere sind in dieser Literaturstelle der Aufbau und die Wirkungsweise der Crimpstation seht detailliert erläutert. Insoweit wird ausdrücklich auf die EP 0 562 229 B1 verwiesen. A pair of pliers with a crimping station of the generic type is disclosed in EP 0 562 229 B1 described in detail, in particular in this reference the The structure and mode of operation of the crimping station are explained in detail. in this respect Reference is expressly made to EP 0 562 229 B1.

Bei der bekannten Zange ist der Schlitz innerhalb des Transporthebels seitlich durch parallele Leibungsbereiche begrenzt, wobei die lichte Weite des Schlitzes durchgängig - bis auf die erforderlichen Toleranzen - dem Durchmesser des Trommelbolzens entspricht.In the known pliers, the slot is laterally inside the transport lever bounded by parallel reveal areas, the inside width of the slot consistently - to the required tolerances - the diameter of the Drum bolt corresponds.

Dies kann in der Praxis dazu führen, daß es bei dem Versuch, den Trommelbolzen mit dem Transporthebel durch Einführen des Trommelbolzens in den Schlitz zu koppeln, zu gewissen Störungen kommt, da die exakte Position des Schlitzes relativ zum Trommelbolzen durch Toleranzen im übrigen kompletten System letztlich nicht mit der wünschenswerten Präzision erreichbar ist.This may in practice cause it when trying to drum bolt with the transport lever by inserting the drum bolt into the slot couple, some interference occurs because the exact position of the slot relative to the drum bolt due to tolerances in the rest of the complete system ultimately not achievable with the desirable precision.

Der vorliegenden Erfindung liegt insoweit die Aufgabe zugrunde, eine Zange der gattungsgemäßen Art dahingehend zu verbessern, daß das Einführen eines Trommelbolzens in den Schlitz des Transporthebels unter allen Umständen störungsfrei möglich ist.The present invention is based on the object, a pliers of generic type to improve that insertion of a Drum bolt into the slot of the transport lever under all circumstances trouble-free is possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Schlitz des Transporthebels sich zu seiner offenen Seite hin erweitert und im erweiterten Bereich ein größeres lichtes Maß als den Durchmesser des Trommelbolzens aufweist und in Ruheposition mit diesem erweiterten Bereich dem Trommelbolzen gegenüber liegt.This object is achieved in that the slot of Transport levers expanded to its open side and in the extended Area a larger light measure than the diameter of the drum bolt and in rest position with this extended area the barrel bolt is opposite.

Durch den erweiterten Bereich des Schlitzes wird das Einführen oder Einkoppeln des Trommelbolzens in diesen Schlitz wesentlich erleichtert und auch bei relativ großen Toleranzen innerhalb des Gesamt-Systems der Zange ist somit ein störungsfreies Einkoppeln des Trommelbolzens in den Schlitz des Transporthebels immer möglich.Through the extended area of the slot is the insertion or coupling the drum pin in this slot much easier and even at relative Large tolerances within the overall system of pliers is thus a trouble-free coupling of the drum bolt in the slot of the transport lever always possible.

Nach einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, daß der Transporthebel bei Betätigung der Zange in Richtung des Trommelbolzens geschwenkt wird, so daß der Trommelbolzen in einen seinem Durchmesser entsprechenden Bereich des Schlitzes eingreift. According to an advantageous embodiment of the invention, it is provided that the Transport lever when operating the pliers in the direction of the drum bolt is pivoted, so that the drum bolt in a its diameter corresponding area of the slot engages.

Hierdurch wird sichergestellt, daß der Trommelbolzen unmittelbar nach Einführen in den Schlitz innerhalb des erweiterten Bereiches des Schlitzes in eine Position relativ zum Transporthebel gelangt, in der eine nahezu spielfreie Kopplung zwischen Trommelbolzen einerseits und Transporthebel andererseits erreicht ist. Die Längsverschiebung des Transporthebels wird demzufolge zuverlässig in einen entsprechenden Drehwinkelbereich der Crimptrommel übertragen.This ensures that the drum bolt immediately after insertion into the slot within the extended area of the slot into one position arrives relative to the transport lever, in a nearly play-free coupling between drum pin on the one hand and transport lever on the other hand is reached. The longitudinal displacement of the transport lever is therefore reliable in one transmit corresponding angular range of the crimping drum.

Dabei kann auf einfache Art und Weise diese vorteilhafte Funktion dadurch erreicht werden, daß der Transporthebel über eine Gleitschräge in Richtung des Transportbolzens verschwenkt wird.In this case, this advantageous function can thereby in a simple manner be achieved that the transport lever via a sliding slope in the direction of Transport bolt is pivoted.

Eine geringfügige Vorwärtsbewegung des Transporthebels hat somit ein Verschwenken des Transporthebels in Richtung des Trommelbolzens zur Folge, so daß schon nach einem Minimum an Verschiebeweg des Transporthebels eine optimale Kopplung zwischen Transporthebel und Trommelbolzen und damit Crimptrommel sichergestellt ist.A slight forward movement of the transport lever thus has a Pivoting the transport lever in the direction of the drum bolt result, so that after a minimum of displacement of the transport lever a optimal coupling between transport lever and drum bolt and thus Crimping drum is ensured.

In den Zeichnungen ist mit dem Bezugszeichen 1 eine Zange mit einer Crimpstation 2 zum Aufcrimpen einer Aderendhülse auf ein abisoliertes Ende eines elektrischen Leiters bezeichnet.FIG. 6 shows the detail labeled VI in FIG. 5 in an enlarged view. In the drawings, the reference numeral 1, a pair of pliers with a Crimping station 2 for crimping a wire end ferrule on a stripped end of a called electrical conductor.

Die Crimpstation 2 weist eine Crimptrommel 3 auf, die um eine Achse 4 drehbar sowie längs um diese Achse 4 aus einer Ruheposition (siehe Figuren 1-4) in eine Arbeitsposition (siehe Figuren 5 und 6) verschiebbar ist.The crimping station 2 has a crimping drum 3 which is rotatable about an axis 4 and along this axis 4 from a rest position (see Figures 1-4) in one Working position (see Figures 5 and 6) is displaceable.

Insgesamt ist die Crimptrommel 3 innerhalb eines Zangengehäuses 5 gelagert, wobei das Zangengehäuse 5 in seinem der Crimptrommel 3 abgewandten hinteren Ende mit einem feststehenden, ersten Handhebel 6 einstückig verbunden ist.Overall, the crimping drum 3 is mounted within a clamp housing 5, wherein the tong housing 5 in its crimping drum 3 facing away from the rear End is integrally connected to a fixed, first hand lever 6.

Weiterhin ist im Zangengehäuse 5 ein zweiter, beweglicher Handhebel 7 schwenkbar gelagert , der in seinem in das Zangengehäuse 5 hineinragenden vorderen Bereich eine nicht weiter dargestellte Antriebseinrichtung aufweist, die mit einem Antriebsbolzen 8 versehen ist. Dieser Antriebsbolzen 8 greift in ein winkelförmiges Langloch 9 eines Transporthebels 10 ein, der bei Betätigung des beweglichen Handhebels 7 im Sinne des Pfeiles A in Figur 2 und in Figur 4 nach vorne, d. h., in Richtung der Crimptrommel 3, beweglich und nach Freigabe des beweglichen Handhebels 7 entgegen dieser ursprünglichen Verschieberichtung wieder zurückbewegbar ist.Furthermore, in the clamp housing 5, a second, movable hand lever 7th pivotally mounted, which protrudes in his in the pliers housing 5 front region has a drive device, not shown, the is provided with a drive pin 8. This drive pin 8 engages in a angular slot 9 of a transport lever 10, which upon actuation of the movable hand lever 7 in the direction of arrow A in Figure 2 and in Figure 4 according to in front, d. h., In the direction of the crimping drum 3, movable and after release of the movable hand lever 7 against this original displacement direction is moved back again.

Die auf der Achse 4 verschiebbar gelagerte Crimptrommel 3 ist auf der dem Transporthebel 10 zugewandten rückseitigen Stirnseite mit mindestens einem Trommelbolzen 11 ausgestattet. Eine axiale Verschiebung der Crimptrommel 3 führt zu einer Kopplung des besagten Trommelbolzens mit dem Transporthebel 10 dadurch, daß der Trommelbolzen 11 in einen Schlitz 12 des Transporthebels 10 hineinragt. In dieser gekoppelten Stellung führt nun eine Längsbewegung des Transporthebels 10 zu einer entsprechenden Verdrehung der Crimptrommel 3.The slidably mounted on the axis 4 crimping drum 3 is on the Transport lever 10 facing rear end face with at least one Drum bolt 11 equipped. An axial displacement of the crimping drum 3 leads to a coupling of the said drum bolt with the transport lever 10th in that the drum pin 11 in a slot 12 of the transport lever 10th protrudes. In this coupled position now performs a longitudinal movement of the Transport lever 10 to a corresponding rotation of the crimping drum. 3

In der gekoppelten Stellung von Trommelbolzen 11 und Transporthebel 10 ist die Crimptrommel gegen axiale Verschiebung vorübergehend gesichert. Nach Ausführung eines Arbeitstaktes - vollständiges Verschieben des Transporthebels 10 nach vorne und vollständiges Zurückbewegen des Transporthebels 10 in seine ursprüngliche Ruhestellung - ist diese axiale Blockierung der Crimptrommel 3 wieder aufgehoben und durch entsprechende Federbelastung wird die Crimptrommel 3 wieder in ihre vom Transporthebel 10 entkoppelte Stellung zurückbewegt.In the coupled position of the barrel pin 11 and transport lever 10 is the Crimping drum temporarily secured against axial displacement. To Execution of a work cycle - complete movement of the transport lever 10 forward and complete retraction of the transport lever 10 in his original rest position - is this axial locking of the crimping drum 3rd lifted again and by appropriate spring load is the Crimping drum 3 again in their decoupled from the transport lever 10 position moved back.

Die axiale Verschiebung der Crimptrommel 3 in die Kopplungsposition erfolgt durch Einführen eines Endes eines elektrischen Leiters in die Crimptrommel zum Zwecke des Aufcrimpens einer Aderendhülse.The axial displacement of the crimping drum 3 takes place in the coupling position by inserting one end of an electrical conductor into the crimping drum for Purpose of crimping a wire end ferrule.

In der Ruhestellung von Crimptrommel 3 und Transporthebel 10 liegt der Trommelbolzen 11 im erweiterten Bereich 12a des Schlitzes 12 gegenüber, was die Figuren 2 und 4 besonders deutlich zeigen. Da das lichte Maß des erweiterten Bereiches 12a des Schlitzes 12 größer ist als der Durchmesser des Trommelbolzens 11, ist das Einführen des Trommelbolzens 11 in den Bereich des Schlitzes 12 in jedem Falle störungsfrei möglich. Eine Betätigung des Transporthebels 10 führt nicht nur zu einer Verschiebung des Transporthebels 10 in Richtung der Crimptrommel 3, sondern - durch eine schräg ansteigende Gleitfläche 13 (siehe Figuren 4 und 6) - auch zu einer Verschwenkung des Transporthebels 10 in Richtung des Trommelbolzens 11. Dadurch gelangt der untere, dem Durchmesser des Trommelbolzens 11 entsprechende Bereich des Schlitzes 12 in eine Anlageposition zum Trommelbolzen 11, so daß nun eine praktisch spielfreie Kopplung zwischen dem besagten Trommelbolzen 11 und dem Schlitz 12 des Transporthebels 10 erreicht ist.In the rest position of crimping drum 3 and transport lever 10 is the Drum pin 11 in the extended portion 12 a of the slot 12 opposite, which is the Figures 2 and 4 show particularly clearly. Because the clear dimension of the extended area 12a of the slot 12 is larger than the diameter of the drum bolt 11, the insertion of the drum pin 11 in the region of the slot 12 in every case possible without interference. An actuation of the transport lever 10 leads not only to a displacement of the transport lever 10 in the direction of Crimping drum 3, but - by a sloping sliding surface 13 (see Figures 4 and 6) - also to a pivoting of the transport lever 10 in Direction of the drum bolt 11. This allows the lower, the diameter the drum pin 11 corresponding portion of the slot 12 in a Abutment position to the drum pin 11 so that now a virtually backlash Coupling between the said barrel pin 11 and the slot 12 of the Transport lever 10 is reached.

Durch diese Konstruktion wird einerseits das Einfügen des Trommelbolzens 11 in den Bereich des Schlitzes 12 vereinfacht und sicher gestaltet, gleichzeitig wird aber auch erreicht, daß der effektiv nutzbare Verschiebeweg des Transporthebels 10 in eine exakt definierte Drehwinkelbewegung der Crimptrommel 3 umgesetzt wird.By this construction, on the one hand, the insertion of the drum pin 11 in the area of the slot 12 simplified and made safe, but at the same time Also achieved that the effectively usable displacement of the transport lever 10 in a precisely defined rotational angular movement of the crimping drum 3 is implemented.

Dadurch wird die Betätigung oder Benutzung der Crimpstation 2 insgesamt vereinfacht und Störungen beim Einführen des Trommelbolzens 11 in den Schlitz 12 werden auch bei unvermeidlichen Toleranzen innerhalb des gesamten Systems zuverlässig vermieden.Thereby, the operation or use of the crimping station 2 becomes total simplified and interference during insertion of the drum pin 11 in the slot 12 will also be at inevitable tolerances throughout the system reliably avoided.

Da die Erreichung dieses Zieles Zweck der vorliegenden Erfindung ist, wurde auf eine detailliertere Beschreibung der Crimptrommel sowie deren Gesamtsteuerung an dieser Stelle verzichtet. Es wird in diesem Zusammenhang noch einmal auf die EP 0 652 229 B1 verwiesen, in der der gesamte, recht komplexe Aufbau der Crimptrommel und deren Gesamtsteuerung und Wirkungsweise ausführlich beschrieben ist. Die entsprechenden Beschreibungsteile werden insoweit ausdrücklich zum Bestandteil der vorliegenden Anmeldung gemacht.Since the achievement of this aim is the purpose of the present invention has been on a more detailed description of the crimping drum and its overall control omitted at this point. It will be in this context again on the EP 0 652 229 B1, in which the entire, rather complex structure of Crimping drum and its overall control and operation in detail is described. The corresponding parts of description are so far expressly made part of the present application.

Wie in der vorerwähnten Literaturstelle auch beschrieben ist, weist eine Crimptrommel 3 in der Regel vorteilhafterweise mehrere Gesenke zur Bearbeitung von unterschiedlich dimensionierten elektrischen Leitern auf. Dies bedingt, daß die Crimptrommel 3 in verschiedene, nutzbare Arbeitspositionen verdreht werden kann. Entsprechend ist dann eine Crimptrommel 3 an ihrer dem Transporthebel 10 zugewandten Stirnseite auch mit mehreren Trommelbolzen 11 ausgestattet, um die Crimptrommel in jeder eingenommenen Arbeitsstellung sicher antreiben zu können.As also described in the aforementioned reference, has a Crimping drum 3 usually advantageously several dies for processing of different sized electrical conductors. This requires that the Crimping drum 3 are rotated in different, usable working positions can. Accordingly, then a crimping drum 3 at its the transport lever 10th facing end face also equipped with a plurality of barrel bolts 11 to the Drive the crimping drum safely in each working position can.
