Das Verpressen von Aderendhülsen mit einem abisolierten Leiterende bzw. mit den Litzen eines Leiters ist im Stand der Technik auch als Crimpen bekannt. Beim Crimpen werden zwei Komponenten durch plastische Verformung miteinander verbunden, so dass eine homogene, schwer lösbare Verbindung zwischen dem Leiter und der Aderendhülse besteht. Crimpen wird als Alternative zum Löten oder Schweißen bei der Herstellung von elektrischen Verbindungen angewendet. Mit Hilfe eines Handautomaten bzw. einer Crimpzange werden die Adern eines Kabels mit einer Aderendhülse formschlüssig verbunden. Dabei sind relativ hohe Kräfte aufzubringen. Meist sollen mehrere Aderendhülsen nacheinander mit entsprechenden Leitern verpresst werden. Um dabei möglichst zeitsparend vorzugehen, gibt es Crimpwerkzeuge mit einem Vorratsmagazin, in denen Aderendhülsen aufbewahrt werden. Nach dem Verpressen einer Aderendhülse kann die nächste Aderendhülse in das Werkzeug manuell oder automatisch eingelegt werden.The pressing of wire end ferrules onto a stripped conductor end or onto the strands of a conductor is also known in the art as crimping. Crimping involves joining two components together through plastic deformation, creating a homogeneous, difficult-to-break connection between the conductor and the wire end ferrule. Crimping is used as an alternative to soldering or welding in the creation of electrical connections. Using a manual machine or crimping pliers, the wires of a cable are positively connected to a wire end ferrule. Relatively high forces are required for this process. Usually, several wire end ferrules need to be crimped onto corresponding conductors one after the other. To save time, crimping tools are available with a storage magazine for wire end ferrules. After one wire end ferrule has been crimped, the next wire end ferrule can be inserted into the tool manually or automatically.

Die Transporteinrichtung weist als wesentlichen Bestandteil ein Transportrad auf, das über seinen Umfang gleichmäßig verteilte Vertiefungen aufweist und um eine Achse drehbar ist. Das Abtrennen einer einzelnen Aderendhülse vom Streifen erfolgt dabei beim eigentlichen Crimpvorgang. Dabei wird der Verbindungssteg zwischen der vordersten Aderendhülse und der nachfolgenden Aderendhülse abgerissen, indem ein beweglicher Pressbacken die vorderste Aderendhülse radial nach außen drückt, also der normale Radius der Vertiefungen überschritten wird, so dass sich die vorderste Aderendhülse radial nach außen verlagert.The DE 42 41 224 C1 discloses a crimping tool with a cylindrical magazine for holding a wire end ferrule strip. The magazine is arranged at a distance from the actual crimping station so that the beginning of the wire end ferrule strip is fed from the magazine through an opening in the housing of the crimping tool into the area of a transport device. The transport device has as an essential component a transport wheel which has recesses evenly distributed around its circumference and which can be rotated about an axis. The separation of an individual wire end ferrule from the strip takes place during the actual crimping process. The connecting web between the foremost wire end ferrule and the following wire end ferrule is torn off by a movable pressing jaw pressing the foremost wire end ferrule radially outwards, i.e. the normal radius of the recesses is exceeded, so that the foremost wire end ferrule is displaced radially outwards.

Nachteilig bei den vorgenannten Magazinen und Handautomaten ist die Handhabung. Es ist mitunter mühsam die einzelnen Aderendhülsen in das Magazin einzulegen. Beim Einführen von Litzen in miteinander verbundene Aderendhülsen kann es vorkommen, dass Litzen umgebogen und nicht in die Aderendhülse eingesteckt werden, da die Unbeweglichkeit des Handautomaten das Einlegen der Leiter erschwert. Dadurch können fehlerhafte Crimpverbindungen entstehen, die mitunter zu Schäden in Geräten führen, in denen der Leiter mit der Aderendhülse eingebaut wird.A disadvantage of the aforementioned magazines and handheld devices is their handling. It can be difficult to insert individual wire end ferrules into the magazine. When inserting stranded wires into interconnected wire end ferrules, the wires may be bent and not inserted into the ferrule because the rigidity of the handheld device makes inserting the conductors difficult. This can result in faulty crimp connections, which can sometimes lead to damage in devices in which the conductor is installed with the wire end ferrule.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Magazin zur Verarbeitung von Aderendhülsen sowie ein Handwerkzeug mit einem entsprechenden Magazin anzugeben, die eine einfachere Handhabung und eine Verbesserung der Prozesssicherheit gewährleisten.The present invention is therefore based on the object of providing a magazine for processing wire end ferrules and a hand tool with a corresponding magazine, which ensure easier handling and improved process reliability.

Gemäß einer ersten Lehre bezieht sich die Erfindung auf ein Magazin, bei dem die zuvor hergeleitete Aufgabe gelöst ist. Das erfindungsgemäße Magazin ist zunächst und im Wesentlichen dadurch gekennzeichnet, dass das Gehäuse eine Magazin-Ebene aufweist in der die Aderendhülsen vom Aderendhülsenstreifen vereinzelbar sind, dass in der Magazin-Ebene eine Schneidvorrichtung vorgesehen ist, durch die die Aderendhülsen voneinander vereinzelbar sind, dass in der Magazin-Ebene ein Vorschubmechanismus vorgesehen ist, durch den der Aderendhülsenstreifen in der Magazin-Ebene transportierbar ist, dass die vereinzelten Aderendhülsen zur Verarbeitung in eine Gesenk-Ebene beförderbar sind, und dass die Magazin-Ebene und die Gesenk-Ebene voneinander verschieden sind. Dadurch, dass die Magazin-Ebene und die Gesenk-Ebene voneinander verschieden sind, kann eine Aderendhülse vom Aderendhülsenstreifen vereinzelt und in die Montageposition verbracht werden, ohne, dass die vereinzelte Aderendhülse bereits in der Gesenk-Ebene angeordnet ist. Auf diese Weise ist es möglich, dass eine Aderendhülse in der Gesenk-Ebene verarbeitet wird, beispielsweise mit den Litzen eines Leiters verpresst wird, wobei gleichzeitig die nächste Aderendhülse von dem Aderendhülsenstreifen vereinzelt und in die Montageposition verbracht wird. Die verpresste Aderendhülse wird dann zusammen mit einem verpressten Leiter aus dem Magazin entfernt, wobei die nächste Aderendhülse schon in der Montageposition bereitsteht. Ein weiterer Leiter kann somit direkt nach Entfernen der verpressten Aderendhülse in das Magazin eingeführt werden, sodass die Aderendhülse von der Montageposition in die Gesenk-Ebene verbracht wird und verpresst werden kann.According to a first teaching, the invention relates to a magazine in which the previously derived object is achieved. The magazine according to the invention is first and essentially characterized in that the housing has a magazine level in which the wire end ferrules can be separated from the wire end ferrule strip, that a cutting device is provided in the magazine level by which the wire end ferrules can be separated from one another, that a feed mechanism is provided in the magazine level by which the wire end ferrule strip can be transported in the magazine level, that the separated wire end ferrules are fed into a die level for processing can be conveyed, and that the magazine level and the die level are different from one another. Because the magazine level and the die level are different from one another, a wire end ferrule can be separated from the wire end ferrule strip and brought into the assembly position without the separated wire end ferrule already being arranged in the die level. In this way, it is possible for a wire end ferrule to be processed in the die level, for example, to be crimped onto the strands of a conductor, while at the same time the next wire end ferrule is separated from the wire end ferrule strip and brought into the assembly position. The crimped wire end ferrule is then removed from the magazine together with a crimped conductor, with the next wire end ferrule already ready in the assembly position. Another conductor can therefore be inserted into the magazine directly after the crimped wire end ferrule has been removed, so that the wire end ferrule is moved from the assembly position to the die level and can be crimped.

Das Einführen eines Leiters in die Aderendhülse kann über eine Leitereinführöffnung im Gehäuse realisiert werden. Für das einfache Einbringen eines Leiters bzw. der Litzen eines Leiters in die Aderendhülse kann bei einer Ausgestaltung der Erfindung vorgesehen sein, dass die Leitereinführöffnung trichterförmig ausgestaltet ist, wobei die trichterförmige Leitereinführöffnung konisch in Richtung auf die zu verarbeitende Aderendhülse zuläuft. Der Leiter kann dann unkompliziert in die relativ große Trichteröffnung eingeführt werden und wird aufgrund der Geometrie der Leitereinführöffnung zur Aderendhülse geführt. Ein fehlerhaftes Einführen des Leiters ist somit ausgeschlossen.A conductor can be inserted into the wire end ferrule via a conductor insertion opening in the housing. For easy insertion of a conductor or the strands of a conductor into the wire end ferrule, one embodiment of the invention can provide a funnel-shaped conductor insertion opening that tapers conically toward the wire end ferrule to be processed. The conductor can then be easily inserted into the relatively large funnel opening and, due to the geometry of the conductor insertion opening, is guided to the wire end ferrule. Incorrect insertion of the conductor is thus impossible.

Das Gehäuse des Magazins kann eine beliebige Geometrie aufweisen. Vorzugsweise ist das Gehäuse zylinderförmig ausgestaltet. Es kann aber auch eine andere rotationssymmetrische oder unsymmetrische Form aufweisen.The magazine housing can have any geometry. Preferably, the housing is cylindrical. However, it can also have another rotationally symmetrical or asymmetrical shape.

Zur einfachen Bedienung des Magazins ist bei einer ersten Ausgestaltung vorgesehen, dass die vereinzelte Aderendhülse durch die Schneidvorrichtung in eine Montageposition verbringbar ist. In der Montageposition kann ein Leiter in die Aderendhülse eingeführt werden und von dort in die Gesenk-Ebene befördert werden. In der Gesenk-Ebene wird die Aderendhülse verarbeitet. Währenddessen kann eine weitere Aderendhülse in die Montage-Position überführt werden.To simplify operation of the magazine, a first design provides for the separated wire end ferrule to be moved into an assembly position by the cutting device. In the assembly position, a conductor can be inserted into the wire end ferrule and from there transported to the die level. The wire end ferrule is processed in the die level. Meanwhile, another wire end ferrule can be transferred to the assembly position.

Bei einer weiteren Ausgestaltung des erfindungsgemäßen Magazins ist vorgesehen, dass der Vorschubmechanismus als federnder Rastarm ausgestaltet ist, der einen linearen Vorschub der Aderendhülsen ermöglicht. Ein federnder Rastarm kann auf einfache Weise die Aderendhülsen innerhalb des Magazins verschieben. Dazu ist denkbar, dass der federnde Rastarm in seiner Längserstreckung quer zur Transportrichtung der Aderendhülsen bzw. des Aderendhülsenstreifens angeordnet ist, so dass er in Transportrichtung auslenkbar ist. Der federnde Rastarm kann zur besseren Mitnahme der Aderendhülsen in dem Bereich, in dem er die Aderendhülsen berührt, der Kontur der Aderendhülsen nachempfunden sein. Üblicherweise weisen die Aderendhülsen einen kreisrunden Querschnitt auf, sodass auch denkbar ist, dass der federnde Rastarm einen Teil einer Kreisbahn im Berührungsbereich, also dem Bereich in dem der federnde Rastarm die Aderendhülsen berührt, beschreibt. Der federnde Rastarm hat dann eine etwa schaufelförmige Kontur. Die schaufelförmige bzw. kreisrunde Kontur hat den Vorteil, dass der Rastarm besser wegfedern kann, wenn er zurückgezogen wird und somit über die nächste Aderendhülse gleitet bzw. hinter der nächsten Aderendhülse einrastet.In a further embodiment of the magazine according to the invention, the feed mechanism is designed as a resilient latching arm, which enables linear advancement of the wire end ferrules. A resilient latching arm can easily move the wire end ferrules within the magazine. For this purpose, it is conceivable that the resilient latching arm is arranged in its longitudinal extent transverse to the transport direction of the wire end ferrules or the wire end ferrule strip, so that it can be deflected in the transport direction. To improve the transport of the wire end ferrules, the resilient latching arm can be modeled on the contour of the wire end ferrules in the area in which it contacts the wire end ferrules. Wire end ferrules usually have a circular cross-section, so it is also conceivable for the resilient latching arm to describe part of a circular path in the contact area, i.e. the area in which the resilient latching arm contacts the wire end ferrules. The resilient latching arm then has an approximately shovel-shaped contour. The shovel-shaped or circular contour has the advantage that the locking arm can spring back better when it is retracted and thus slides over the next wire end ferrule or locks behind the next wire end ferrule.

Um die Handhabung des Magazins zu verbessern, ist bei einer weiteren Ausgestaltung vorgesehen, dass der Vorschubmechanismus von einer Ausgangsposition in eine Vorschubposition verschiebbar ist. In der Ausgangsposition liegt der Rastarm des Vorschubmechanismus an einer Aderendhülse an. Wenn die Kraft, die durch den Vorschubmechanismus aufgebracht wird, größer ist, als die Haltekraft, die auf die Aderendhülse bzw. auf den Aderendhülsenstreifen wirkt, dann wird der Vorschubmechanismus in die Vorschubposition verschoben. Dadurch, dass der federnde Rastarm in der Ausgangsposition des Vorschubmechanismus an einer Aderendhülse anliegt, wird diese beim Verbringen des Vorschubmechanismus von der Ausgangsposition in die Vorschubposition ebenfalls verschoben.To improve handling of the magazine, a further embodiment provides for the feed mechanism to be movable from a starting position to a forward position. In the starting position, the locking arm of the feed mechanism rests against a wire end ferrule. If the force applied by the feed mechanism is greater than the holding force acting on the wire end ferrule or the wire end ferrule strip, the feed mechanism is moved to the forward position. Because the spring-loaded locking arm rests against a wire end ferrule in the starting position of the feed mechanism, the wire end ferrule is also moved when the feed mechanism is moved from the starting position to the forward position.

Wenn der Vorschubmechanismus wieder in die Ausgangsposition verbracht wird, wird der federnde Rastarm ebenfalls zurück in die Ausgangsposition verbracht. Durch die federnde Ausgestaltung kann der federnde Rastarm an den Aderendhülsen entlang gleiten, sodass er in der vorgespannten Position wieder an einer Aderendhülse anliegt, ohne diese zu verschieben.When the feed mechanism is returned to its original position, the spring-loaded locking arm also returns to its original position. The spring-loaded design allows the spring-loaded locking arm to slide along the wire end ferrules, so that in the pre-tensioned position, it rests against a wire end ferrule again without displacing it.

Um zu vermeiden, dass die Reibung zwischen dem federnden Rasthaken und den Aderendhülsen zu groß ist, kann bei einer weiteren Ausgestaltung ein weiterer federnder Rastarm vorgesehen sein, der die Bewegung der Aderendhülsen bzw. des Aderendhülsenstreifens sperrt, wenn der Vorschubmechanismus in die Ausgangsposition verbracht wird, wobei die Bewegung in die Vorschubposition freigegeben ist. So kann der federnde Rastarm des Vorschubmechanismus beim Verbringen in die Ausgangsposition an den Aderendhülsen ausgelenkt werden und eine der Aderendhülsen in der Ausgangsposition hintergreifen, ohne, dass beim Verbringen in die Ausgangsposition ebenfalls die Aderendhülsen bewegt werden und der federnde Rastarm nicht an der Aderendhülse vorbei ausgelenkt werden kann.To prevent excessive friction between the spring-loaded locking hook and the wire end ferrules, a further embodiment can provide an additional spring-loaded locking arm that blocks the movement of the wire end ferrules or the wire end ferrule strip when the feed mechanism is moved to the starting position, while allowing movement into the feeding position. Thus, the spring-loaded locking arm of the feed mechanism can be deflected along the wire end ferrules when moved to the starting position and engage behind one of the wire end ferrules in the starting position without also moving the wire end ferrules when moved to the starting position, and the spring-loaded locking arm cannot be deflected past the wire end ferrule.

Die Freigabe der Aderendhülsen kann bei einer bevorzugten Ausgestaltung des Magazins dadurch erfolgen, dass der Vorschubmechanismus und die Schneidvorrichtung derart miteinander verbunden sind, dass der Vorschubmechanismus in der Vorschubposition angeordnet ist, wenn sich die Schneidvorrichtung in einer neutralen Position befindet, also nicht betätigt ist. Das bedeutet dass der Vorschubmechanismus in die Vorschubposition verbracht wird, wenn die Schneidvorrichtung nicht mehr betätigt wird. Die Schneidvorrichtung kann dabei über ein mechanisches Bauteil, vorzugsweise einen Hebel mit dem Vorschubmechanismus verbunden sein. Durch gelenkige Lagerungen der Hebel kann erreicht werden, dass der Vorschubmechanismus etwa quer zur Schneidvorrichtung bewegt wird.In a preferred embodiment of the magazine, the wire end ferrules can be released by connecting the feed mechanism and the cutting device in such a way that the feed mechanism is arranged in the feed position when the cutting device is in a neutral position, i.e., not actuated. This means that the feed mechanism is moved into the feed position when the cutting device is no longer actuated. The cutting device can be connected to the feed mechanism via a mechanical component, preferably a lever. Articulated lever bearings can ensure that the feed mechanism is moved approximately transversely to the cutting device.

Bei einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Schneidrichtung der Schneidvorrichtung quer zur Orientierung des Aderendhülsenstreifens im Abschnitt der Vereinzelung verläuft. Somit kann die Schneidvorrichtung genau in den Zwischenraum zwischen zwei Aderendhülsen, also dem Verbindungssteg, eingreifen und den Verbindungssteg durchtrennen und anschließend wieder in die entgegengesetzte Richtung bewegt werden. Auf diese Weise blockiert die Schneidvorrichtung nicht die Transportrichtung der Aderendhülsen bzw. des Aderendhülsenstreifens.In a further embodiment of the invention, the cutting direction of the cutting device runs transversely to the orientation of the wire-end ferrule strip in the separation section. This allows the cutting device to precisely engage the space between two wire-end ferrules, i.e., the connecting web, and sever the connecting web before being moved back in the opposite direction. This way, the cutting device does not block the transport direction of the wire-end ferrules or the wire-end ferrule strip.

Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, dass die Schneidvorrichtung eine Klinge aufweist und dass durch die Schneidvorrichtung jeweils ein Verbindungssteg zwischen zwei Aderendhülsen durchtrennbar ist. Die Klinge kann die Verbindungsstege unproblematisch durchtrennen. Wenn die Klinge scharf genug ist, reicht eine einfache lineare Bewegung der Klinge aus, um die Verbindungsstege zu durchtrennen. Bei einer bevorzugten Ausgestaltung kann die Klinge leicht angeschrägt ausgebildet sein, sodass sie zunächst an einem Punkt des Verbindungssteges ansetzt und bei weiterem Vorschub der Klinge den Verbindungssteg entlang einer Linie durchtrennt. Somit wird die lineare Bewegung der Klinge quer zur Transportrichtung des Aderendhülsenstreifens in eine quer zur Bewegung der Klinge ausgerichtete Schneidbewegung überführt.An advantageous embodiment of the invention provides that the cutting device has a blade, and that the cutting device can cut through a connecting web between two wire end ferrules. The blade can easily cut through the connecting webs. If the blade is sharp enough, a simple linear movement of the blade is sufficient. to sever the connecting webs. In a preferred embodiment, the blade can be slightly beveled so that it initially engages at a point on the connecting web and, as the blade is advanced further, cuts through the connecting web along a line. Thus, the linear movement of the blade transverse to the transport direction of the wire end ferrule strip is converted into a cutting movement oriented transversely to the movement of the blade.

Zur leichteren Vereinzelung der Aderendhülsen ist bei einer weiteren Ausgestaltung der Erfindung vorgesehen, dass die Schneidvorrichtung ein Element, vorzugsweise einen Keil, umfasst, durch den die Aderendhülsen während des Schneidvorgangs voneinander entfernbar sind. Das zusätzlich Element kann konisch zulaufen, sodass beim Schneidvorgang bzw. nach dem Schneidvorgang die Aderendhülsen weiter auseinander gedrückt werden, wenn das konisch zulaufende Element zwischen die beiden Aderendhülsen bewegt werden. Der Keil kann dabei so angeordnet sein, dass die vereinzelte Aderendhülse durch den Keil innerhalb des Magains schräg gestellt wird.To facilitate the separation of the wire end ferrules, a further embodiment of the invention provides that the cutting device comprises an element, preferably a wedge, by which the wire end ferrules can be separated from one another during the cutting process. The additional element can be tapered so that the wire end ferrules are pushed further apart during or after the cutting process when the tapered element is moved between the two wire end ferrules. The wedge can be arranged such that the separated wire end ferrule is tilted within the magazine by the wedge.

Um die Handhabung des Magazins weiter zu verbessern, ist bei einer weiteren Ausgestaltung des erfindungsgemäßen Magazins vorgesehen, dass die Schneidvorrichtung von der neutralen Position in eine Schneidposition verbringbar ist und dass die Schneidvorrichtung durch ein betätigbares Rückstellelement in der neutralen Position gehalten ist. Um einen weiteren Schneidvorgang auszulösen wird das Rückstellelement ausgelenkt, sodass die Schneidvorrichtung aus der neutralen Positoion in die Schneidposition überführt ist. Das Rückstellelement kann beispielsweise eine Feder sein. Aufgrund der Federkraft des Rückstellelements ist die Schneidvorrichtung bemüht, in die neutrale Position zurückzukehren. Das Rückstellelement kann durch entsprechende Feststellmechanismen wie Rasthaken oder ähnliches in der Schneidposition gehalten werden. Vorzugsweise wird diese durch Betätigung eines Hebels oder einem ähnlichen Bauteil in die Schneidposition überführt und durchtrennt die den Verbindungssteg zwischen zwei Aderendhülsen. Wird das Rückstellelement freigegeben, ist wird die Schneidvorrichtung wieder in die neutrale Position befördert.In order to further improve the handling of the magazine, a further embodiment of the magazine according to the invention provides that the cutting device can be moved from the neutral position into a cutting position and that the cutting device is held in the neutral position by an actuatable return element. In order to trigger a further cutting process, the return element is deflected so that the cutting device is moved from the neutral position into the cutting position. The return element can be a spring, for example. Due to the spring force of the return element, the cutting device strives to return to the neutral position. The return element can be held in the cutting position by appropriate locking mechanisms such as latching hooks or the like. This is preferably moved into the cutting position by actuating a lever or a similar component and severs the connecting web between two wire end ferrules. If the return element is released, the cutting device is moved back to the neutral position.

Um das Verbringen einer Aderendhülse von der Magazin-Ebene in die Gesenk-Ebene zu erleichtern, ist bei einer vorteilhaften Ausgestaltung des erfindungsgemäßen Magazins vorgesehen, dass eine in der Montageposition befindliche Aderendhülse in einem Winkel ungleich 0 Grad zur Längserstreckung der Aderendhülsen des Aderendhülsenstreifens angeordnet ist. Der Winkel zwischen der Längserstreckung der Aderendhülse des Aderendhülsenstreifens und der Längserstreckung der Aderendhülse, die sich in der Montageposition befindet, beträgt vorzugsweise 20 Grad.In order to facilitate the transfer of a wire end sleeve from the magazine level to the die level, an advantageous embodiment of the magazine according to the invention provides that a The wire end ferrule is positioned at an angle other than 0 degrees to the longitudinal extension of the wire end ferrules of the wire end ferrule strip. The angle between the longitudinal extension of the wire end ferrule of the wire end ferrule strip and the longitudinal extension of the wire end ferrule in the assembly position is preferably 20 degrees.

Die vereinzelte Aderendhülse kann durch ein Halteelement, beispielsweise einen Keil, während des Schneidvorgangs von den benachbarten Aderendhülsen weggedrückt werden. Dadurch wird zum einen das Durchtrennen des Verbindungsstegs unterstützt und zum anderen wird die Aderendhülse schräg gestellt. Aufgrund des Winkels in der Montageposition muss die Aderendhülse nicht unmittelbar über einer möglichen Öffnung im Gehäuse positioniert werden, durch den eine Aderendhülse in die Gesenk-Ebene befördert wird. Ein Leiter bzw. die Litzen eines Leiters werden in einer Linie zu der sich in der Montageposition befindlichen Aderendhülse in die Aderendhülse eingeführt. Eine mögliche Öffnung im Gehäuse, durch die eine Aderendhülse in die Gesenk-Ebene verbracht wird, muss lediglich auch in etwa auf der Linie der Bewegung des eingeführten Leiters liegen, damit die Aderendhülse aus der Montageposition in die Gesenk-Ebene befördert werden kann.The separated wire end ferrule can be pushed away from the neighboring wire end ferrules by a holding element, such as a wedge, during the cutting process. This not only supports the severing of the connecting web, but also tilts the wire end ferrule. Due to the angle in the assembly position, the wire end ferrule does not have to be positioned directly over a possible opening in the housing through which a wire end ferrule is moved into the die plane. A conductor or the strands of a conductor are inserted into the wire end ferrule in line with the wire end ferrule in the assembly position. Any possible opening in the housing through which a wire end ferrule is moved into the die plane simply has to lie roughly in the line of movement of the inserted conductor so that the wire end ferrule can be moved from the assembly position into the die plane.

Gemäß einer zweiten Lehre bezieht sich die Erfindung auf ein Handwerkzeug zum Verpressen von Aderendhülsen mit einem abisolierten Leiterende bzw. mit den Litzen eines Leiters mit einem Magazin für Aderendhülsen, bei dem die zuvor hergeleitete Aufgabe gelöst ist. Das erfindungsgemäße Handwerkzeug ist zunächst und im Wesentlichen dadurch gekennzeichnet, dass das Magazin erfindungsgemäß ausgestaltet ist.According to a second teaching, the invention relates to a hand tool for crimping wire end ferrules to a stripped conductor end or to the strands of a conductor, with a magazine for wire end ferrules, in which the previously derived object is achieved. The hand tool according to the invention is first and essentially characterized in that the magazine is designed according to the invention.

Die Ausführungen zu dem erfindungsgemäßen Magazin gelten entsprechend auch für das erfindungsgemäße Handwerkzeug mit einem befestigten Magazin.The statements regarding the magazine according to the invention also apply accordingly to the hand tool according to the invention with a fixed magazine.

Der zuvor genannte Handgriff des Handwerkzeugs kann zangenartig ausgestaltet sein. Der Handgriff kann aber auch lediglich zur Betätigung eines Antriebmechanismus dienen. Das Handwerkzeug kann beispielsweise elektrisch, pneumatisch oder hydraulisch betrieben werden. Der Vorschubmechanismus und die Schneidvorrichtung des Magazins sind bei diesen Ausführungsbeispielen an die lineare bzw. rotative Bewegung des Verpressens der Aderendhülsen gekoppelt.The aforementioned handle of the hand tool can be designed like a pair of pliers. However, the handle can also serve solely to actuate a drive mechanism. The hand tool can be operated electrically, pneumatically, or hydraulically, for example. In these embodiments, the feed mechanism and the cutting device of the magazine are coupled to the linear or rotary movement of the crimping of the wire end ferrules.

Mit dem Handwerkzeug ist es möglich, die Aderendhülse mit dem Leiter bzw. mit den Litzen eines Leiters formschlüssig zu verbinden. Dabei kommt ein Fügeverfahren, das Crimpen, zum Einsatz. Die Aderendhülse wird mit dem eingeführten Leiter in die Gesenk-Ebene in das Gesenk eingelegt und über die Pressbacken derart zusammengedrückt, dass die Aderendhülse und der in der Aderendhülse befindliche Teil des Leiters eine plastische Verformung erfahren. Um die durch den Anwender aufbringbare Kraft zu erhöhen kann das Handwerkzeug einen Kniehebel aufweisen, da sich das Übersetzungsverhältnis zwischen aufgewendeter Kraft zu resultierender Kraft bzw. von primärem Hub zu sekundärem Hub während der Bewegung kontinuierlich verschiebt und somit zunächst höhere Geschwindigkeiten der Pressbacken bei geringerer Kraft und im entscheidenden Bereich eine geringe Geschwindigkeit bei einer hohen Kraft erreicht werden kann.The hand tool can be used to form a positive-locking connection between the wire end ferrule and the conductor or strands of a conductor. This involves a joining process known as crimping. The wire end ferrule, with the conductor inserted, is inserted into the die plane and pressed together by the pressing jaws in such a way that the wire end ferrule and the part of the conductor located in the wire end ferrule undergo plastic deformation. To increase the force that can be applied by the user, the hand tool can be equipped with a toggle lever. This is because the transmission ratio between applied force and resulting force, or from primary stroke to secondary stroke, continuously shifts during the movement. This allows the pressing jaws to initially achieve higher speeds with less force and, in the crucial range, a low speed with a high force.

Durch das mit dem Handwerkzeug verbundene Magazin können Aderendhülsen, in die bereits ein Leiter auf die oben genannte vorteilhafte Art eingesteckt ist, dem Gesenk des Handwerkzeugs zugeführt werden. Eine Aderendhülse, die sich in der Montageposition befindet kann somit einen Leiter aufnehmen.The magazine connected to the hand tool allows wire end ferrules, into which a conductor has already been inserted in the advantageous manner described above, to be fed into the hand tool's die. A wire end ferrule in the assembly position can thus accommodate a conductor.

Für eine komfortable Bedienung des Magazins mit dem Handgriff ist bei einer Ausgestaltung vorgesehen, dass der Handgriff derart mit dem Magazin zusammenwirkt, dass die Schneidvorrichtung betätigt ist, wenn sich der Handgriff in der ersten Position befindet. In der ersten Position stehen die Schenkel des Handgriffs in einem größeren Winkel zueinander als in der zweiten Position, das heißt zum Verbringen der Schenkel von der ersten in die zweite Position muss der Handgriff zusammengedrückt werden. Das Zusammendrücken bewirkt auch ein Verpressen der Aderendhülse in der Gesenk-Ebene, wobei die Gesenk-Ebene genau mit dem Gesenk des Handwerkzeugs zusammenfällt. Nach dem Verpressen wird der Handgriff wieder entspannt, das heißt von der zweiten Position in die ersten Position verbracht. Beim Verbringen von der zweiten Position in die erste Position wird auch gleichzeitig die Schneidvorrichtung betätigt, sodass eine weitere Aderendhülse bereits vereinzelt ist, wenn das Handwerkzeug bereit für das Verpressen einer weiteren Aderendhülse ist.To ensure convenient operation of the magazine using the handle, one design provides for the handle to interact with the magazine in such a way that the cutting device is actuated when the handle is in the first position. In the first position, the arms of the handle are at a greater angle to one another than in the second position, meaning that to move the arms from the first to the second position, the handle must be pressed together. This pressing together also causes the wire end ferrule to be crimped in the die plane, with the die plane coinciding exactly with the die of the hand tool. After crimping, the handle is released again, meaning it is moved from the second position to the first position. When the handle is moved from the second position to the first position, the cutting device is actuated at the same time, so that another wire end ferrule has already been separated when the hand tool is ready to crimp another wire end ferrule.

Weiter ist bei einer weiteren Ausgestaltung des erfindungsgemäßen Handwerkzeugs vorgesehen, dass der Handgriff derart mit dem Magazin zusammenwirkt, dass der Vorschubmechanismus betätigt ist, wenn der Handgriff betätigt ist. Der Vorschubmechanismus transportiert somit den Aderendhülsenstreifen innerhalb der Magazin-Ebene, wenn der Handgriff betätigt wird. Wenn bereits eine Aderendhülse durch die Schneidvorrichtung vereinzelt wurde, wird beim nächsten Betätigen des Handgriffs der Aderendhülsenstreifen durch den Vorschubmechanismus so weit transportiert, dass die nächste Aderendhülse von dem Aderendhülsenstreifen vereinzelt werden kann.Furthermore, in a further embodiment of the hand tool according to the invention, it is provided that the handle interacts with the magazine in such a way that that the feed mechanism is activated when the handle is operated. The feed mechanism thus transports the wire-end ferrule strip within the magazine level when the handle is operated. If a wire-end ferrule has already been separated by the cutting device, the wire-end ferrule strip is transported by the feed mechanism far enough the next time the handle is operated that the next wire-end ferrule can be separated from the wire-end ferrule strip.

Für eine einfache Bedienbarkeit sind Umleitungsmittel vorgesehen. Die Umleitungsmittel wirken derart mit dem zangenartigen Handgriff und den Pressbacken zusammen, dass durch eine Handbetätigung des Handgriffs das Verpressen mindestens einer Aderendhülse mit einem abisolierten Leiter durchführbar ist. Auf diese Weise kann der Anwender mit möglichst geringem Aufwand die Aderendhülsen mit einem Leiter Verpressen, indem lediglich der Handgriff manuell betätigt wird.For ease of use, diversion devices are provided. The diversion devices interact with the pliers-like handle and the crimping jaws in such a way that the crimping of at least one wire end ferrule onto a stripped conductor can be performed by manually operating the handle. This allows the user to crimp the wire end ferrules onto a conductor with minimal effort, simply by manually operating the handle.

Bei einer vorteilhaften Ausgestaltung des erfindungsgemäßen Handwerkzeugs ist vorgesehen, dass das Magazin lösbar, insbesondere durch eine Rastverbindung, mit dem Handwerkzeug verbunden ist. Die Montage des Magazins an dem Handwerkzeug kann beispielsweise durch eine Drehbewegung, ähnlich eines Bajonettverschlusses, oder durch Aufstecken erfolgen. Die genaue Positionierung des Magazins erfolgt dabei über Stifte oder andere Erhebungen, die am Magazin ausgebildet sind und in korrespondierende Ausnehmungen eingreifen. Die Stifte bzw. Erhebungen können auch an dem Rahmen des Handwerkzeugs ausgebildet sein und die korrespondierenden Ausnehmungen entsprechend an dem Magazin. Die Aufrastung kann beispielsweise auch durch umgebogene Halteelemente verwirklicht werden, die auf der gegenüberliegenden Seite, auf der das Magazin angebracht ist das Handwerkzeug hintergreifen. Durch die Positionierung des Magazins ist ein Verrutschen des Magazins somit ausgeschlossen, wenngleich das Magazin auf einfache Weise an dem Handwerkzeug befestigt werden kann.In an advantageous embodiment of the hand tool according to the invention, the magazine is detachably connected to the hand tool, in particular by a snap-in connection. The magazine can be mounted on the hand tool, for example, by a rotating movement, similar to a bayonet lock, or by plugging it on. The precise positioning of the magazine is achieved via pins or other elevations that are formed on the magazine and engage in corresponding recesses. The pins or elevations can also be formed on the frame of the hand tool, and the corresponding recesses can be formed on the magazine. The snap-in connection can also be achieved, for example, by bent-over holding elements that engage behind the hand tool on the side opposite to that on which the magazine is attached. The positioning of the magazine thus prevents the magazine from slipping, although the magazine can be easily attached to the hand tool.

Um die Qualität der Verpressung der Aderendhülse zu erhöhen, sind bei einer vorteilhaften Ausgestaltung des erfindungsgemäßen Handwerkzeugs mehr als zwei Pressbacken vorgesehen, so dass eine symmetrische Verpressung zwischen Aderendhülse und dem abisolierten Leiterende bzw. mit den Litzen des Leiters erfolgt. Die Pressbacken werden dann nicht nur von zwei Seiten aufeinander zubewegt, sondern aus mehreren Richtungen derart zueinander bewegt, dass ein symmetrischer Querschnitt zwischen den Pressbacken entsteht, d.h. dass ein symmetrisches Gesenk entsteht. Ein Vorteil der Verwendung von mehr als zwei Pressbacken besteht darin, dass die Geometrie des Gesenks für einen großen Querschnittsbereich gleich bzw. sehr ähnlich bleibt. Die Pressbacken schließen nach Art einer Blende, wodurch sich die Geometrie des Querschnitts des Gesenks beim Schließen nicht merklich verändert, da die Pressbacken gleichmäßig aufeinander zubewegt werden.To increase the quality of crimping the wire end ferrule, an advantageous embodiment of the hand tool according to the invention provides more than two crimping jaws, so that a symmetrical crimping occurs between the wire end ferrule and the stripped conductor end or with the conductor strands. The crimping jaws are then moved toward each other not only from two sides, but from several directions. moved so that a symmetrical cross-section is created between the pressing jaws, i.e., a symmetrical die is created. One advantage of using more than two pressing jaws is that the geometry of the die remains the same or very similar over a large cross-sectional area. The pressing jaws close like a shutter, meaning that the geometry of the cross-section of the die does not change noticeably upon closing, as the pressing jaws are moved evenly toward each other.

Dafür ist bei einer vorteilhaften Ausgestaltung der Erfindung vorgesehen, dass die Pressbacken derart angeordnet sind, dass eine quadratische Verpressung erfolgt. Bei einer alternativen Ausgestaltung der Erfindung ist vorgesehen, dass die Pressbacken derart angeordnet sind, dass eine hexagonale Verpressung erfolgt.For this purpose, an advantageous embodiment of the invention provides that the pressing jaws are arranged such that a square pressing action occurs. In an alternative embodiment of the invention, the pressing jaws are arranged such that a hexagonal pressing action occurs.

Im Einzelnen gibt es eine Vielzahl von Möglichkeiten, das erfindungsgemäße Magazin sowie das erfindungsgemäße Handwerkzeug auszugestalten und weiterzubilden. Dazu wird verwiesen sowohl auf die den Patentansprüchen 1 und 11 nachgeordneten Patentansprüche als auch auf die nachfolgende Beschreibung eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung.

Fig. 1 zeigt ein Magazin 1 zur Verarbeitung von Aderendhülsen 2, die über Verbindungsstege 3 zu einem Aderendhülsenstreifen 4 verbunden sind. Das Magazin weist ein Gehäuse 5 auf, in dem die Aderendhülsen 2 angeordnet sind. Zur Vereinzelung der Aderendhülsen 2 ist eine Schneidvorrichtung 6 vorgesehen. Für den Transport der Aderendhülsen 2 bzw. der Aderendhülsenstreifen 4 innerhalb des Magazins 1 ist ein Vorschubmechanismus 7 vorgesehen. Der Vorschubmechanismus 7 umfasst einen federnden Rastarm 8, der in Fig. 1 zwischen zwei Aderendhülsen 2 angeordnet ist. Zur Vereinzelung der Aderendhülsen 2 ist an der Schneidvorrichtung 6 eine Klinge 9 angeordnet. Der Vorschubmechanismus 7 ist mit einem Rückstellelement 10 verbunden. Fig. 1 shows a magazine 1 for processing wire end ferrules 2, which are connected via connecting webs 3 to form a wire end ferrule strip 4. The magazine has a housing 5 in which the wire end ferrules 2 are arranged. A cutting device 6 is provided for separating the wire end ferrules 2. A feed mechanism 7 is provided for transporting the wire end ferrules 2 or the wire end ferrule strip 4 within the magazine 1. The feed mechanism 7 comprises a spring-loaded locking arm 8, which Fig. 1 is arranged between two wire end ferrules 2. A blade 9 is arranged on the cutting device 6 to separate the wire end ferrules 2. The feed mechanism 7 is connected to a return element 10.

Die Schneidvorrichtung 6 und der Vorschubmechanismus 7 sind über einen Winkelhebel 11 derart miteinander verbunden, dass ein Verkippen des Winkelhebels 11 sowohl zu einer Bewegung der Schneidvorrichtung 6 als auch zu einer Bewegung des Vorschubmechanismus 7 führt. Der Winkelhebel 11 ist insgesamt T-förmig ausgestaltet, sodass insgesamt drei Hebelarme, ein erster Hebelarm 12, ein zweiter Hebelarm 13 und ein dritter Hebelarm 14 vorhanden sind. Der erste Hebelarm 12 ist über eine Langlochverbindung 15 gelenkig mit der Schneidvorrichtung 6 verbunden. Der zweite Hebelarm 13 ist mit dem Vorschubmechanismus gelenkig 7 verbunden. Der dritte Hebelarm 14 ragt aus dem Gehäuse 5 heraus, sodass er außerhalb des Gehäuses 5 betätigbar ist und somit gleichzeitig die Schneidvorrichtung 6 und den Vorschubmechanismus 7 betätigt.The cutting device 6 and the feed mechanism 7 are connected to one another via an angle lever 11 such that tilting the angle lever 11 leads to a movement of both the cutting device 6 and the feed mechanism 7. The angle lever 11 is T-shaped overall, so that a total of three lever arms are present: a first lever arm 12, a second lever arm 13, and a third lever arm 14. The first lever arm 12 is articulated to the cutting device 6 via a slotted hole connection 15. The second lever arm 13 is articulated to the feed mechanism 7. The third lever arm 14 protrudes from the housing 5 so that it can be actuated outside the housing 5 and thus actuates the cutting device 6 and the feed mechanism 7 simultaneously.

Aus den Fig. 1 und Fig. 2 ist das Zusammenwirken der Schneidvorrichtung 6 und des Vorschubmechanismus 7 ersichtlich. In Fig. 1 ist das Rückstellelement 10 entspannt. Die Schneidvorrichtung 6 ist nicht betätigt, das heißt die Klinge 9 hat den größtmöglichen Abstand zu den Aderendhülsen 2. Wenn die Schneidvorrichtung 6 nicht betätigt ist, dann ist der Vorschubmechanismus 7 derart orientiert, dass der federnde Rastarm 8 an der zu vereinzelnden Aderendhülse 2 anliegt, sodass der Aderendhülsenstreifen 4 für die Vereinzelung in Position gebracht ist.From the Fig. 1 and Fig. 2 the interaction of the cutting device 6 and the feed mechanism 7 is visible. In Fig. 1 the return element 10 is released. The cutting device 6 is not actuated, i.e. the blade 9 is at the greatest possible distance from the wire end ferrules 2. When the cutting device 6 is not actuated, the feed mechanism 7 is oriented such that the spring-loaded locking arm 8 rests against the wire end ferrule 2 to be separated, so that the wire end ferrule strip 4 is positioned for separation.

In Fig. 2 ist die Schneidvorrichtung 6 betätigt, das heißt die Klinge 9 hat den Verbindungssteg 3 zwischen zwei Aderendhülsen 2 durchtrennt. Das Rückstellelement 10 ist ausgelenkt und bemüht, die Schneidvorrichtung 6 in die neutrale Position zu überführen. Die Klinge 9 ist in einer keilfömigen Aufnahme 16 angeordnet. Die keilförmige Aufnahme 16 drückt gegen die zu vereinzelnde Aderendhülse 2, sodass diese von dem Aderendhülsenstreifen 4 wegbewegt wird. Gleichzeitig ist die keilförmige Aufnahme 16 so angeordnet, dass sie die vereinzelte Aderendhülse 2 beim Wegdrücken schräg stellt. In dieser schrägen Montageposition kann die Aderendhülse 2 dann von der Magazin-Ebene in die Gesenk-Ebene transportiert werden.In Fig. 2 the cutting device 6 is actuated, i.e. the blade 9 has severed the connecting web 3 between two wire end sleeves 2. The reset element 10 is deflected and strives to move the cutting device 6 into the neutral position. The blade 9 is arranged in a wedge-shaped receptacle 16. The wedge-shaped receptacle 16 presses against the wire end ferrule 2 to be separated, causing it to move away from the wire end ferrule strip 4. At the same time, the wedge-shaped receptacle 16 is arranged such that it tilts the separated wire end ferrule 2 as it is pushed away. In this tilted assembly position, the wire end ferrule 2 can then be transported from the magazine level to the die level.

Während die Schneidvorrichtung 6 betätigt wird, wird der Vorschubmechanismus 7 in seine eigentliche Ausgangsposition verbracht. Bei der Bewegung von der Vorschubposition, also der Position in dem der Aderendhülsenstreifen 4 zur Vereinzelung ausgerichtet ist, in die Ausgangsposition wird der federnde Rastarm 9 ausgelenkt und gleitet an der nächstgelegenen Aderendhülse 2 über deren Durchmesser ab, bis sie wieder in dem Zwischenraum zwischen zwei Aderendhülsen 2 ohne Auslenkung eingreifen kann. Bei erneuten Betätigung des Vorschubmechanismus 7 verschiebt der federnde Rasthaken 9 dann den Aderendhülsenstreifen 4 in die Position, in der die nächste Aderendhülse 2 vereinzelt werden kann.While the cutting device 6 is actuated, the feed mechanism 7 is moved to its actual starting position. During the movement from the feed position, i.e., the position in which the wire end ferrule strip 4 is aligned for separation, to the starting position, the spring-loaded locking arm 9 is deflected and slides along the diameter of the nearest wire end ferrule 2 until it can again engage in the space between two wire end ferrules 2 without deflection. When the feed mechanism 7 is actuated again, the spring-loaded locking hook 9 then moves the wire end ferrule strip 4 into the position in which the next wire end ferrule 2 can be separated.

Fig. 3 zeigt das Magazin gemäß den Fig. 1 und Fig. 2 mit einem Gehäusedeckel 17 und einer Leitereinführöffnung 18. In die Leitereinführöffnung 18 ist ein Leiter 19 bzw. die Litzen des Leiters 19 einführbar. Da die vereinzelte Aderendhülse 2 in der Montageposition schräg in Bezug auf die übrigen Aderendhülsen 2 ausgerichtet ist, wird auch der Leiter 19 zunächst schräg in die Leitereinführöffnung 18 eingeführt. Dazu weist die Leitereinführöffnung einen trichterförmigen Abschnitt 20 auf. Durch den trichterförmigen Abschnitt 20 wird der Leiter 19 korrekt positioniert, sodass die Litzen des Leiters 19 korrekt in die Aderendhülse eingeführt werden können. Durch weiteres Einführen des Leiters 19 wird die Aderendhülse 2 samt Leiter 19 aus der Montageposition bzw. aus der Magazin-Ebene in die Gesenk-Ebene befördert, in der die Aderendhülse 2 dann verpresst werden kann. Anschließend kann der Leiter 19 wieder gerade aus der Leitereinführöffnung 18 herausgezogen werden, während bereits die nächste Aderendhülse 2 in der Montageposition positioniert ist. Fig. 3 shows the magazine according to the Fig. 1 and Fig. 2 with a housing cover 17 and a conductor insertion opening 18. A conductor 19 or the strands of the conductor 19 can be inserted into the conductor insertion opening 18. Since the isolated wire end ferrule 2 is aligned at an angle in relation to the other wire end ferrules 2 in the assembly position, the conductor 19 is also initially inserted at an angle into the conductor insertion opening 18. For this purpose, the conductor insertion opening has a funnel-shaped section 20. The funnel-shaped section 20 correctly positions the conductor 19 so that the strands of the conductor 19 can be correctly inserted into the wire end ferrule. By further inserting the conductor 19, the wire end ferrule 2 together with the conductor 19 is moved from the assembly position or from the magazine level to the die level, where the wire end ferrule 2 can then be crimped. The conductor 19 can then be pulled straight out of the conductor insertion opening 18 again, while the next wire end ferrule 2 is already positioned in the assembly position.

Fig. 4 zeigt das Magazin 1 gemäß den Fig. 1 , 2 und 3 in einer perspektivischen Darstellung. Es ist erkennbar, dass der dritte Hebelarm 14 des Winkelhebels 11 teilweise aus dem Gehäuse 5 heraustritt. Somit kann der Winkelhebel 11 auf einfache Weise auch außerhalb des Gehäuses 5 betätigt werden. Die Aderendhülsen 2 sind innerhalb des Gehäuses in einem Kanal 21 geführt. Fig. 4 shows the magazine 1 according to the Fig. 1 , 2 and 3 in a perspective view. It can be seen that the third lever arm 14 of the angle lever 11 partially protrudes from the housing 5. Thus, the angle lever 11 can also be easily operated outside the housing 5. The wire end ferrules 2 are guided in a channel 21 within the housing.

Fig. 5 und Fig. 6 zeigen ein Handwerkzeug 22 zum Verpressen von Aderendhülsen 2 oder genauer zum Crimpen von Aderendhülsen 2 mit absisolierten Leiterenden bzw. mit den Litzen eines Leiters 19. Das Handwerkzeug 22 weist einen zangenartigen Handgriff 23 auf, der dazu bestimmt ist, mehrere hier nicht dargestellte Pressbacken zueinander zu bewegen. Die Pressbacken bilden ein Gesenk, das mit der Gesenk-Ebene zusammenfällt und in das die Aderendhülse 2 eingelegt und verpresst werden kann. Ein Magazin 1 zum Verarbeiten von Aderendülsen 2 ist an dem Handwerkzeug 22 befestigt. Dabei ist das Magazin 1 so angeordnet, dass die Leitereinführöffnung 18 des Magazins so positioniert ist, dass ein Durchführen einer Aderendhülse 2 mit einem eingesteckten Leiter in das Gesenk ohne weiteres möglich ist. Die Aderendhülsen 2 werden in zusammenhängenden Aderendhülsenstreifen 4 in das Magazin 1 eingebracht und innerhalb des Magazins 1 vereinzelt. Durch die Leitereinführöffnung 18 kann ein Leiter 19 in eine Aderendhülse 2, die sich in der Montageposition befindet, eingesteckt werden. Wird der Leiter 19 weiter in die Leitereinführöffnung 18 eingeschoben, wird der Leiter 19 zusammen mit der Aderendhülse 2 in das Gesenk des Handwerkzeugs 22 geleitet und ideal positioniert. Mit Hilfe des Handwerkzeugs 22 kann dann eine Crimpverbindung zwischen dem Leiterende und einer Aderendhülse 2 hergestellt werden. Nach dem Crimpverfahren wird der Leiter 19 zusammen mit der Aderendhülse 2 aus dem Magazin 1 herausgezogen. Fig. 5 and Fig. 6 show a hand tool 22 for crimping wire end ferrules 2 or, more precisely, for crimping wire end ferrules 2 with stripped conductor ends or with the strands of a conductor 19. The hand tool 22 has a pliers-like handle 23 designed to move several pressing jaws (not shown here) towards each other. The pressing jaws form a die that coincides with the die plane and into which the wire end ferrule 2 can be inserted and crimped. A magazine 1 for processing wire end ferrules 2 is attached to the hand tool 22. The magazine 1 is arranged such that the conductor insertion opening 18 of the magazine is positioned such that a wire end ferrule 2 with an inserted conductor can be easily passed through the die. The wire end ferrules 2 are inserted into the magazine 1 in connected wire end ferrule strips 4 and separated within the magazine 1. A wire 19 can be inserted into a wire end ferrule 2 that is in the assembly position through the wire insertion opening 18. If the wire 19 is pushed further into the wire insertion opening 18, the wire 19, together with the wire end ferrule 2, is guided into the die of the hand tool 22 and ideally positioned. With the help of the hand tool 22, a crimp connection can then be created between the wire end and a wire end ferrule 2. After the crimping process, the wire 19, together with the wire end ferrule 2, is pulled out of the magazine 1.

Fig. 5 zeigt das Handwerkzeug 22 mit unbetätigtem Handgriff 23, während Fig. 6 das Handwerkzeug mit betätigtem Handgriff 23 zeigt. Der Handgriff 23 ist mit dem dritten Hebelarm 14 verbunden, sodass eine Betätigung des Handgriffs 23 auch zu einer Betätigung des dritten Hebelarms 14 und somit auch zu einer Betätigung des im Gehäuse 5 des Magazins 1 angeordneten ersten Hebelarms 12 und des zweiten Hebelarms 13 führt. Auf diese Weise kann die Vereinzelung und Positionierung einer Aderendhülse 2 in die Montageposition automatisch durch Betätigung des Handgriffs 23 erfolgen. Fig. 5 shows the hand tool 22 with the handle 23 not actuated, while Fig. 6 shows the hand tool with the handle 23 actuated. The handle 23 is connected to the third lever arm 14, so that actuation of the handle 23 also leads to actuation of the third lever arm 14 and thus also to actuation of the first lever arm 12 and the second lever arm 13 arranged in the housing 5 of the magazine 1. In this way, the separation and positioning of a wire end ferrule 2 in the assembly position can take place automatically by actuating the handle 23.

Fig. 7 zeigt das Handwerkzeug 22 gemäß Fig. 5 und Fig. 6 mit einem eingesteckten Leiter 19, der gerade mit einer Aderendhülse 2 verpresst wird. Die Aderendhülsenstreifen 4 können über eine Einführöffnung 24 leicht zugänglich von außen in das Magazin 1 eingeführt werden. Sobald der Aderendhülsensstreifen 4 in den Bereich des Vorschubmechanismus 7 verbracht ist, kann das Vereinzeln und Positionieren mittels des Handgriffs 23 erreicht werden. Fig. 7 shows the hand tool 22 according to Fig. 5 and Fig. 6 with an inserted conductor 19, which is currently being crimped with a wire end ferrule 2. The Wire end ferrule strips 4 can be easily inserted into the magazine 1 from the outside via an insertion opening 24. Once the wire end ferrule strip 4 has been brought into the area of the feed mechanism 7, separation and positioning can be achieved using the handle 23.
