- the plate spring assembly 29 is formed as an axial sequence axially stacked disc springs 36 or even in the immovable handle part 1 b.
- the disc spring assembly 29 is advantageously and compactly arranged between the two base plates 6a and 6b, extends substantially parallel to the forceps handle 1b in the forceps handle and protrudes only with outer peripheral portions in the elongated windows or openings 37 in the base plates 6a, 6b (see in particular Fig.
- the disc spring assembly 29 In order to mount the disc spring assembly 29 easy and to be able to couple with a deflection mechanism, it has a pull rod 31 (see in particular Fig. 1a . b . c and Fig. 8a and b ), which passes through the plate spring assembly and its plate springs 36 axially.
- the plate spring assembly 29 and its plate springs 36 are between a clamping sleeve 33 at one end of the tie rod (to the free end of Pliers handle 1b down) and a spring stop 30 at the other end of the pull rod 31 (set to the pliers head 1a).
- the spring stop 30 is seated on the pull rod 31 and limits the displacement of the disc springs, in which it is supported on the base plates 6a, b as an abutment. Axially following the spring stop 30, the plate springs 36 are lined up on the pull rod 31. At the opposite - other - end of the drawbar 31, a device is provided, with which the preset axial path of the drawbar over which the disc springs 36 are lined up on the drawbar 31, adjust, which also changes the bias of the plate spring assembly 29 and a Adjustment of this bias allows.
- This adjustment and adjustment can be realized in various ways.
- an adjustable screw 33 can be screwed into a thread in the pull rod 31, so that the path between the spring stop 30 and the screw in the pull rod is adjustable.
- the thickness of a spacer sleeve 32 can be varied at this end of the pull rod 31 for adjustment, which is supported against a screw 33 which is inserted into the end of the pull rod 31 facing away from the spring stop 30.
- Other types of adjustment with screws / nuts and the like. are conceivable.
- Such a desired functional relationship between the closed size of the crimping die 5 and the crimping of the crimping die 5 can be adjusted.
- the punch holder 41 rotates uniformly with the pressure ring 39 and further crimping of the contact is prevented. This is achieved by the rotatably mounted in the base plate 6 punch holder 41.
- the punch holder 41 is fixed (immovable) connected to a balance lever 28, which exemplarily and advantageously consisting of a slide pin 35, which cooperates with the balance lever, via a Umlenkkinematik Actuating lever 18, a slide pin 16 and the pull rod 31, the plate spring assembly 29 deflects and thus realized the force - displacement - compensation of the crimping die 5, so that the crimping die 4 automatically adjusts to the corresponding crimping cross section ( Fig. 5 and 6 ).
- a balance lever 28 which exemplarily and advantageously consisting of a slide pin 35, which cooperates with the balance lever, via a Umlenkkinematik Actuating lever 18, a slide pin 16 and the pull rod 31, the plate spring assembly 29 deflects and thus realized the force - displacement - compensation of the crimping die 5,
- cup spring assembly 29 in the crimping tool 1 allows it by a co-axial or alternating layering / (sequence of the plate springs 36 or by a combination of these measures, with the groups or individually arranged disc springs of the plate spring package 29 spring characteristics of progressive over linear to degressive To represent force-Weg and thus optimally adapt the crimping to the crimping cross sections to be processed from small to large.
- the plate springs of the disc spring pact can also form groups or sub-packages 29a, 29b (see also Fig. 11 ). Several of the groups 29a, 29b then form in the assembled state, the actual (total) plate spring package of the crimping tool (see Fig. 1b ). About the Konzticianswinkel the disc springs can achieve a desired force design and on the number of juxtaposed disc springs of plate spring package 29 a desired path design.
- the groups 29a, 29b of Figure 11 In each case, two of the groups 29a, 29b in the region of the respectively smallest outside diameter (so to speak) are each made up of a number of disk springs (which are each in each case designed as conical disk springs with perforation at the top of the conical disc springs) Fig. 11 then join in the tool in the plate spring assembly 29 again preferably several of these groups (see Fig. 1b ) This arrangement has proven to be particularly advantageous in terms of the success of the invention.
- Fig. 6 It is shown how the plate spring assembly 29 receives the required residual stroke of the crimping die 4 as elastic deformation work when the crimping die 4 crimping a turned contact 2, or crimping an end sleeve 102 has already moved to block, but still has to be covered, so that the barrier 24 releases the opening of the crimping die 4.
- the crimping tool 1 thus automatically adjusts itself to the cross section of the turned contact 2 or the ferrule 2 and the conductor cross section to be crimped. This makes it possible to continuously cover the crimping of conductor cross-sections of, for example, 0.08 mm 2 to 6.0 mm 2 with only one crimping die 4.
- the crimping tool 1 can be closed until the lock 24 is skipped and opens automatically.
- the integration of the diaphragm spring assembly 29 in the base plates 6 allows a compact design of the crimping tool 1 while precise tuning to the required force / displacement compensation. Compared to other designs, less space is required for the same performance. In addition, simplifies the design and the design of the spring for the force / displacement compensation of the crimping tool 1 in an advantageous manner.
- Fig. 7 is shown how by turning an eccentric bolt 17, the angular position of the punch holder 41 and the balance lever 28 to each other can be changed, whereby the closing size of the crimping die 5 can be adjusted.
- An adjusting disc 21 and a flat head screw 22 fix the eccentric pin 17 in the set position.
- the eccentric 17 only serves for basic adjustment and possibly the compensation of manufacturing tolerances. Usually, the eccentric pin 17 is not adjusted by the user of the crimping tool 1.
- FIG. 9 an inventive crimping tool 1 with a locator 43 for turned contacts 2 is shown.
- the locator 43 is set to the type of contact to be processed and engages via a toothing 44 on the pliers head 1a in the set position.
- the contact 2 (not shown) is inserted into the opened crimp die 4 and held in crimping position by the locator 43. Easy handling and crimping at the intended location of the contact 2 is realized so process reliable.
- the handle 26 or 19 of the tool 1 By actuating the handle 26 or 19 of the tool 1, the contact 2 on the conductor 3 (not shown) is crimped.
- a conductor 3 is shown, on the stripped end of which, for example, a turned contact 2 has been crimped.
- the rotated contact 2 was pressed with a four-point crimp.

Dadurch wird gewährleistet, dass mit dem Crimpwerkzeug gedrehte Kontakte bzw. Aderendhülsen mit einen möglichst großen Querschnittsbereich vercrimpt werden können.With the subject matter of
Dabei ist das wenigstens eine Federpaket nach einer Variante als Tellerfederpaket ausgebildet. Dieses weist weiter zwei oder mehr vorzugsweise axial gestapelte Tellerfedern auf. Tellerfedern sind auf einfache Weise kompakt in und an dem Werkzeug, insbesondere der Zange, unterzubringen. Durch die Verwendung eines Tellerfederpakets als Kraft-/Weg-Ausgleichsvorrichtung kann in einfacher und vorteilhafter Weise die Federkennlinie je nach Erfordernissen eingestellt werden, so kann durch eine entsprechende Schichtung der vorzugsweise eingesetzten Tellerfedern (oder ggf. auch anderer Federn) im Tellerfederpaket eine progressive, lineare oder degressive Kennlinie erzeugt werden .In this case, the at least one spring assembly is designed according to a variant as a plate spring package. This further comprises two or more, preferably axially stacked disc springs. Disc springs are compact in a simple manner in and on the tool, in particular the pliers to accommodate.

Ein besonderer Vorteil des Werkzeugs liegt darin, dass durch das verwendete Federpaket (linear, progressiv oder degressiv abgestimmt) das Werkzeug wesentlich besser auf eine große Bandbreite von Querschnitten angepasst werden kann und somit das Crimpergebnis über den Querschnittsbereich ein besseres ist.A particular advantage of the tool is that the tool can be adapted much better to a wide range of cross-sections by the spring assembly used (linear, progressive or degressive) and thus the Crimpergebnis over the cross-sectional area is better.
Alternativ ist es nach einer anderen Variante des Anspruchs 1 vorgesehen, das eine Federpaket auf andere Weise auszubilden, so als Schraubenfederpaket auszubilden oder mehrere Elastomerfeder(n), vorzugsweise mit Loch, vorzusehen, insbesondere zu stapeln. In diesem Fall wird vorzugsweise dennoch der grundsätzliche Aufbau verwendet, wie er vorstehend beschrieben worden ist, d.h. dort wo eine oder mehrere Tellerfedern gestapelt sind, werden Schraubenfedern oder Elastomerfedern verwendet, insbesondere von einer Zugstange durchsetzt. Insoweit kann in der nachfolgenden Beschreibung der Ausführungsbeispiele und in den Unteransprüchen der Begriff der "Tellerfeder" auch durch Schraubenfeder oder Elastomerfedern ersetzt werden. Mischformen mit verschiedenen Federarten wie Tellerfedern und Elastomerfedern sind ebenfalls realisierbar.Alternatively, it is provided according to another variant of

Besonders bevorzugt wird es aber, wenn das Tellerfederpaket aus einzelnen Tellerfedern oder Gruppen von gleichsinnig (vorzugsweise axial) geschichteten Tellerfedern gebildet ist, die jeweils einzeln oder als Gruppen wechselsinnig zueinander angeordnet sind. Dadurch kann die Federkennlinie besonders einfach eingestellt werden.However, it is particularly preferred if the disc spring assembly of individual disc springs or groups of the same direction (preferably axially) layered disc springs is formed, which are each arranged individually or as groups mutually alternating. As a result, the spring characteristic can be adjusted very easily.

Es ist ferner bevorzugt und vorteilhaft, wenn eine Einrichtung vorgesehen ist, mit welcher sich der axiale Weg, über welchen die Teller-, Schrauben- und/oder Elastomerfedern auf die Zugstange aufgereiht sind, verändern lässt, was die Vorspannung des Tellerfeder-, Schrauben- und/oder Elastomerfederpakets verändert.It is further preferred and advantageous if a device is provided, with which the axial path, over which the plate, screw and / or elastomer springs are lined up on the drawbar, can change what the bias of the diaphragm spring, screw and / or Elastomerfederpakets changed.
Um das Federpaket mit dem Crimpgesenk zu koppeln, ist es vorteilhaft, wenn ein Stempelhalter des Crimpgesenks mit einem Ausgleichshebel verbunden ist, der über eine Umlenkkinematik das Teller-, Schrauben- und/oder Elastomerfederpaket auslenken kann bzw. auslenkt.In order to couple the spring assembly with the crimping die, it is advantageous if a punch holder of the crimping die is connected to a compensating lever which can deflect or deflect the plate, screw and / or elastomeric spring assembly via deflecting kinematics.

Unter dem Begriff "Aderendhülsen" werden im Sinne der vorliegenden Erfindung, Crimpkontakte in Form von Hülsen verstanden, die dazu bestimmt und ausgelegt sind, mit einem Crimpvorgang auf die Enden von flexiblen Leitern aufgepresst zu werden. Eine aufgepresste bzw. "verpresste" Aderendhülse kann - dies ist aber nicht zwingend - beispielsweise in Trapez- oder Sechseck- oder Vierkantform ausgeführt sein. Unter dem Begriff "gedrehter Kontakt" 2 werden im Sinne der vorliegenden Erfindung zudem solche Crimpkontakte in Form von Hülsen bzw. Aderendhülsen verstanden, die als gedrehte Teile ausgebildet sind und die ebenfalls dazu bestimmt und ausgelegt sind, mit einem Crimpvorgang auf flexible Leiter, insbesondere mehrdrähtige Leiterenden aufgebracht zu werden . Ein verpresster gedrehter Kontakt 2 kann insbesondere als Drei- oder n-Punkt-Crimp ausgeführt sein.The term "ferrules" in the context of the present invention, crimp contacts in the form of sleeves understood that are intended and designed to be pressed with a crimping on the ends of flexible conductors to become. A pressed on or "pressed" wire end sleeve can - but this is not mandatory - be designed for example in trapezoidal or hexagonal or square shape. For the purposes of the present invention, the term "turned contact" 2 is also understood as meaning such crimp contacts in the form of sleeves or ferrules which are designed as turned parts and which are likewise designed and configured with a crimping process on flexible conductors, in particular stranded wires Ladder ends to be applied.

Das Crimpwerkzeug 1 ist als handbetätigbare Crimpzange ausgebildet. Es weist einen Zangenkopf 1a und zwei relativ zueinander bewegliche Handgriffe 1b und 1c auf, von denen der eine Zangengriff 1c schwenkbar an dem Zangenkopf 1a angelenkt ist und von denen der andere Zangengriff 1b nicht schwenkbar mit dem Zangenkopf 1a verbunden ist.The crimping
Der Zangenkopf bzw. das Crimpwerkzeug 1 weist ferner zwei parallel zueinander angeordnete Basisbleche 6a, b (in
Jedenfalls eines der beiden Basisbleche 6a, weist im Bereich des Zangenkopfes 1a eine zentrale Öffnung 7 nach Art eines Fensters oder Durchbruchs auf. An der Öffnung - hier zentrisch zur Öffnung 7 ist zwischen den Basisblechen 6a, b eine Crimpstation mit einem Crimpgesenk 4 mit einer automatischen bzw. sich selbsteinstellenden Auslegung auf den zu verarbeitenden Crimphülsen- und Leiterquerschnitt angeordnet.In any case, one of the two
Das Crimpgesenk 4 weist einen Druckring 39 auf, der zwischen den zwei Basisblechen 6a, b koaxial zur kreisförmigen Öffnung 7 (hier nicht dargestellt) angeordnet ist. Der Druckring 39 nimmt in einer zentralen Öffnung das aus drei oder mehr Crimpstempeln 5 und einem Stempelhalter 41 gebildete Crimpgesenk 4 auf. Die Crimpstempel 5 sind dazu jeweils in dem Stempelhalter 41 hier radial zur Öffnung 7 der Basisbleche und einer damit fluchtenden Öffnung des Stempelhalters 41 des Crimpgesenks 4 angeordnet und geführt. Der Stempelhalter 41 ist über mehrere Bolzen 40 fest mit dem Ausgleichshebel 28 verbunden.The crimping
Der Druckring 39 sitzt auf dem Stempelhalter 41 und ist um diesen drehbar. Dazu ist der Druckring 39 über zwei Bolzen 13 mit dem schwenkbaren Zangengriff 1c bzw. einem Hebel 19 verbunden. Der Hebel 19 kann mit einer Griffschale 26 (hier nicht dargestellt) versehen bzw. verkleidet werden.The
Damit das Crimpgesenk 4 immer sicher bis zu einem Endanschlag betätigt wird, weist der Druckring 39 eine Verzahnung 23 auf, in die eine klinkenartige Sperre 24 an dem oder den Basisblechen 6 eingreifen kann, die ein vorzeitiges, unbeabsichtigtes Öffnen des Crimpgesenks 4 verhindert. Eine Druckfeder 25 zwischen dem beweglichen Zangengriff und den Basisblechen sorgt für das selbständige Öffnen des Crimpgesenks 4 nach dem Vercrimpen des gedrehten Kontakts 2 bzw. der Aderendhülse 102.Thus, the crimping

Der Druckring 39 weist zur Aufnahme des Stempelhalters 41 und der Crimpstempel 5 eine Öffnung auf, deren Geometrie auf einer kreisrunde Bohrung beruht, die am Umfang mit zwei oder mehreren bogenartigen Flächen erweitert ist, welche beim Drehen des Druckringes 39 die Crimpstempel 5 in einem Kontaktbereich berühren und beim drehen des Druckrings 39 radial nach innen bewegen, so dass sie auf den Crimpkontakt einwirken. Der Kontaktbereich S im Druckring 39 kann als Kurve mit konstanter Steigung oder als Kurve mit speziell abgestimmter Steigung zur Optimierung von Hand- und Presskräften ausgeführt sein. Die Crimpstempel 5 werden in dem Stempelhalter 41 radial beweglich gehalten/ gelagert. Die Druckfeder 42 bewegt die Crimpstempel 5 nach dem Crimpvorgang entlang der Kurve S wieder in die Ausgangsposition zurück.The
Um unterschiedliche Kontakt- und Leiterquerschnitte in dem einzigen Crimpgesenk 4 verarbeiten zu können, ist ein Kraft- Wegausgleichs-Vorrichtung vorgesehen. Diese wird konstruktiv einfach durch ein Federpaket aus einer, zwei oder mehreren Federn, hier durch ein Tellerfederpaket 29 aus axial gestapelten Tellerfedern 36, gebildet. Hier ist das Tellerfederpaket 29 als axiale Reihung axial gestapelter Tellerfedern 36 an oder sogar in dem unbeweglichen Griffteil 1b ausgebildet. Bevorzugt ist das Tellerfederpaket 29 vorteilhaft und kompakt zwischen den zwei Basisblechen 6a und 6b angeordnet, erstreckt sich im Wesentlichen parallel zum Zangengriff 1b im Zangengriff und ragt lediglich mit äußeren Umfangsabschnitten in die länglichen Fenster bzw. Durchbrüche 37 in den Basisblechen 6a, 6b ein (siehe insbesondere
Um das Tellerfederpaket 29 einfach montieren und mit einer Umlenkmechanik koppeln zu können, weist es eine Zugstange 31 auf (siehe insbesondere
Der Federanschlag 30 sitzt auf der Zugstange 31 und begrenzt den Verschiebeweg der Tellerfedern, in dem er sich an den Basisblechen 6a, b als Widerlager abstützt. Axial im Anschluss an den Federanschlag 30 sind die Tellerfedern 36 auf die Zugstange 31 aufgereiht. An dem gegenüberliegenden - anderen - Ende der Zugstange 31 ist eine Einrichtung vorgesehen, mit welcher sich der voreingestellte axiale Weg der Zugstange, über welchen die Tellerfedern 36 auf die Zugstange 31 aufgereiht sind, verstellen lässt, was auch die Vorspannung des Tellerfederpakets 29 verändert und eine Einstellung dieser Vorspannung ermöglicht. Dieses Verstellen und Einstellen lässt sich auf verschiedene Weise realisieren. Beispielsweise kann eine verstellbare Schraube 33 in ein Gewinde in der Zugstange 31 eingeschraubt sein, so dass der Weg zwischen dem Federanschlag 30 und der Schraube in der Zugstange verstellbar ist. Alternativ lässt sich die Dicke einer Distanzhülse 32 an diesem Ende der Zugstange 31 zur Einstellung variieren, welche sich gegen eine Schraube 33 abstützt, die in das vom Federanschlag 30 abgewandte Ende der Zugstange 31 eingesetzt ist. Auch andere Arten der Verstellung mit Schrauben / Muttern und dgl. sind denkbar. Derart lässt sich ein gewünschter funktionaler Zusammenhang zwischen dem Schließmaß der Crimpstempel 5 und der Crimpkaft der Crimpstempel 5 einstellen.The
Wird beim Crimpen die für den eingelegten Kontakt definierte Crimpkraft erreicht, dreht sich der Stempelhalter 41 gleichförmig mit dem Druckring 39 mit und ein weiteres Vercrimpen des Kontaktes wird verhindert. Erreicht wird dies durch den im Basisblech 6 drehbar gelagerten Stempelhalter 41. Der Stempelhalter 41 ist fest (unbeweglich) mit einem Ausgleichshebel 28 verbunden, der über eine Umlenkkinematik 14, hier beispielhaft und vorteilhaft bestehend aus einem Gleitbolzen 35, der mit dem Ausgleichhebel zusammenwirkt, einem Betätigungshebel 18, einem Gleitbolzen 16 und der Zugstange 31, das Tellerfederpaket 29 auslenkt und somit den Kraft - Weg - Ausgleich der Crimpstempel 5 realisiert, so dass sich das Crimpgesenk 4 auf den entsprechenden Crimpquerschnitt automatisch einstellt (
Der Einsatz des Tellerfederpakets 29 im Crimpwerkzeug 1 erlaubt es durch eine gleichsinnige bzw. wechselsinnige Schichtung/(Reihung der Tellerfedern 36 oder durch eine Kombinationen dieser Maßnahmen, mit den in Gruppen oder einzeln angeordneten Tellerfedern des Tellerfederpakets 29 Federkennlinien von progressiven über linearen bis hin zu degressiven Kraft- Wegverhalten darzustellen und somit das Crimpergebnis optimal auf die zu verarbeitenden Crimpquerschnitte von klein bis groß anzupassen.The use of the
Um einen genügend großen Wegausgleich zu bieten, ist es vorteilhaft, wenn in dem Tellerfederpaket 29 eine Vielzahl von Tellerfedern vorgesehen ist. Die Tellerfedern des Tellerfederpaktes können dabei auch Gruppen bzw. Unterpakete 29a, 29b bilden (siehe auch
