Abstract

The tool has a pair of cooperating clamp jaws (121, 131), each with a projection (41, 42) at its free end, projecting in the direction of the other clamp jaw. The projections are offset relative to one another, to define a planar intermediate space between them, with a limited overlap between the projections in the open position of the jaws. The inside face of the projections on either side of the intermediate space are serrated, for frictional engagement with the inserted conductor end, so that it is twisted as the jaws are operated. <IMAGE>

Description

Die Erfindung betrifft ein zangenartiges Werkzeug zum Verdrillen des teilweise freigelegten Endbereichs eines eine Litze als Ader aufweisende isolierten Leiters und Ausgestaltungen des Werkzeugs zu einem die gesamte Abfolge der erforderlichen Schritte für das Ansetzen von Endhülsen an mit einer Isolierung versehenen, eine Litze als Ader aufweisenden Leiters zusammenfassenden Gerät.The invention relates to a pair of pliers-like tools for twisting the partially exposed end region of an insulated conductor having a strand as a wire, and refinements of the tool to form a complete sequence of the steps required for attaching end sleeves to conductors provided with insulation and having a strand as a conductor Device.

Soweit Werkzeuge zum Verdrillen des Endbereichs von mit einer Aderendhülse zu versehenden, eine Litze als Ader aufweisende Leiter bekannt sind, weisen diese einen komplizierten, störanfälligen Aufbau auf, die Werkzeuge sind dann auch so ausgelegt, daß die Zugänglichkeit zum Verdrillbereich zu wünschen übrig läßt. Die bekannten Geräte lassen vom Aufbau her im übrigen die Optimierung eines solchen Werkzeuges im Sinne einer Zusammenfassung sämtlicher Elemente für die Abfolge der in Zusammenhang mit dem Ansetzen einer Aderendhülse an einem eine Litze als Ader aufweisenden Leiter erforderlichen Manipulationen in einem Werkzeug nicht zu.Insofar as tools for twisting the end area of conductors to be provided with a wire end sleeve and having a strand as a wire are known, these have a complicated, failure-prone structure, the tools are then also designed such that the accessibility to the twisting area leaves something to be desired. The known devices leave the optimization in the rest of the structure Such a tool in the sense of a summary of all elements for the sequence of the manipulations required in connection with the attachment of a wire end sleeve on a conductor having a strand as a wire in a tool.

Ausgehend vom Stand der Technik liegt der Erfindung zunächst einmal die Aufgabe zugrunde, ein Werkzeug zum Verdrillen des teilweise freigelegten Endbereichs eines eine Litze als Ader aufweisende isolierten Leiters vorzuschlagen, das vom Aufbau her einfach und unkompliziert und somit kaum störanfällig ist und sich dann auch leicht handhaben läßt. Weitergehend liegt der Erfindung die Aufgabe zugrunde, ein Werkzeug anzubieten, mit dem sämtliche Manipulationen in Zusammenhang mit dem Ansetzen einer Aderendhülse an einen eine Litze als Ader aufweisende isolierten Leiter durchführbar sind.Starting from the prior art, the invention is based on the object of proposing a tool for twisting the partially exposed end region of an insulated conductor having a strand as a wire, which is simple and uncomplicated in terms of structure and therefore hardly susceptible to faults and which is then easy to handle leaves. The invention is further based on the object of offering a tool with which all manipulations in connection with the attachment of a wire end sleeve to an insulated conductor having a strand as a wire can be carried out.

Dementsprechend wird zunächst einmal ein zangenartiges Werkzeug zum Verdrillen des teilweise freigelegten Endbereichs eines einer Litze als Ader aufweisenden isolierten Leiters vorgeschlagen, das am freien Ende der Backen von den Backen ausgehende, jeweils auf die andere Backe orientierte, in das Zangenmaul vorspringende Stege aufweist, wobei die Stege einen der Bewegungskurve der Zangenbacken entsprechenden Verlauf aufweisen, auf gegeneinander versetzten, einen Zwischenraum zwischen den Stegen ausbildenden Ebenen verlaufen, einer der Stege eine bei geöffneter Zange eine begrenzte Überdeckung des anderen Steges erbringende Länge aufweist und die einander zugeordneten den Zwischenraum zwischen den Stegen eingrenzenden Flächen griffig ausgelegt sind.Accordingly, a pliers-like tool is first proposed for twisting the partially exposed end region of an insulated conductor having a strand as a wire, which, at the free end of the jaws, extends from the jaws, each oriented towards the other jaw, and projecting into the pliers mouth, the The webs have a course corresponding to the movement curve of the pliers jaws, run on mutually offset planes that form an intermediate space between the webs, one of the webs has a length that provides a limited coverage of the other web when the pliers are open, and the surfaces assigned to one another that delimit the interspace between the webs are designed to be easy to grip.

Bei dem erfindungsgemäßen Drillwerkzeug handelt es sich um eine denkbar einfache und damit unkomplizierte und somit kaum störanfällige Lösung, mit der der weitere Vorteil verbunden ist, daß das Maul des zangenartigen Werkzeugs unbeeinträchtigt für weitere in Zusammenhang mit dem Ansetzen von Aderendhülsen an den freigelegten Enden von eine Litze als Ader aufweisenden isolierten Leiters erforderlichen Elementen, etwa von den Backen des Werkzeuges zuzuordnenden Klemm- und Schneidelementen zum Abisolieren des Leiterendes bleibt. Gleichermaßen läßt sich die erfindungsgemäße Lösung ohne weiteres dann auch an einer existierenden Abisolierzange mit an den Backen der Zange angesetzten Klemm- und Schneidelementen zum Freilegen des Endes des isolierten Leiters realisieren.The drilling tool according to the invention is a very simple and therefore uncomplicated and therefore hardly susceptible to failure, with which the further advantage is connected that the mouth of the pliers-like tool remains unaffected for other elements required for connection of wire end sleeves to the exposed ends of an insulated conductor having a strand as a wire, such as clamping and cutting elements to be assigned to the jaws of the tool for stripping the conductor end . Likewise, the solution according to the invention can then be readily implemented on existing stripping pliers with clamping and cutting elements attached to the jaws of the pliers to expose the end of the insulated conductor.

Ausgestaltungen des erfindungsgemäßen Drillwerkzeugs ergeben sich aus den Unteransprüchen 2 bis 6. Möglichkeiten der Ausgestaltung des Drillwerkzeuges zu einem Werkzeug, mit dem im günstigsten Fall sämtliche in Zusammenhang mit dem Ansetzen von Aderendhülsen an eine Litze als Ader aufweisenden isolierten Leitern erforderliche Arbeitsgänge bewirkt werden können, ergeben sich aus den Unteransprüchen 7 bis 16. Ein in diesem Zusammenhang wesentliches Erfindungsmerkmal ist das Herzstück des Werkzeugs, das heißt die in die Zange eingelagerte Kassette mit den Kulissen für die Elemente zum Verpressen der Aderendhülse auf dem freigelegten Litzenende, zum Abtrennen einer Aderendhülse von einem magazinierten Aderendhülsengurt und gegebenenfalls dann auch zum Ablängen eines Leiters, in Verbindung mit den denkbar einfachen Mechanismen für die Betätigung der Werkzeuge.Embodiments of the drilling tool according to the invention result from subclaims 2 to 6. Possibilities of designing the drilling tool into a tool with which, in the most favorable case, all the operations required in connection with the attachment of wire end sleeves to a stranded wire having insulated conductors can be effected from the subclaims 7 to 16. An essential feature of the invention in this context is the heart of the tool, that is, the cassette embedded in the pliers with the scenes for the elements for pressing the ferrule onto the exposed strand end, for separating a ferrule from a magazine Wire end sleeve belt and then, if necessary, also to cut a conductor to length, in connection with the very simple mechanisms for operating the tools.

Das zangenartig ausgebildete Werkzeug, als Ganzes dargestellt in den Figuren 1, 3 und 5, besteht in an sich bekannter Weise aus den durch die Achse 11 zusammengefaßten Schenkeln 12 und 13, von den der Schenkel 13 den Schenkel 12 durchsetzt, deren Überstände über die Achse 11, die Zangenbacken 121 und 131, mit den Klemm- und Schneidelementen 21, 21' sowie 22, 22' versehen sind mit denen die erste Stufe des Abisolierens des mit einer Aderendhülse zu versehenden Leiterendes in der Weise erfolgt, daß der im Sinne des Pfeiles A in den Figuren 1 und 12 in das Werkzeug eingeführte isolierte (311) aus einer Litze bestehende Leiter 31 beim Betätigen der Zange zum einen zwischen den Klemmelementen 21, 21' festgelegt und zum andern die Isolierung 311 von den Schneidelementen 22, 22' angeschnitten wird und die angeschnittene Isolierung 311' sodann durch gegenläufige Verlagerung der Klemm- und Schneidelemente 21, 21' und 22, 22' im Sinne des Doppelpfeiles B in Figur 12 auf dem vor dem Anschnitt liegenden Endbereich 31' der Litze 31 begrenzt abgezogen wird (Pfeil C in Figur 12), begrenzt deshalb, weil die unmittelbare Einwirkung der Drillelemente auf die zu verdrillende Litze zu vermeiden ist. Mit 14 ist eine Rückstellfeder bezeichnet, die die Zangenschenkel in ihre Ausgangslage zurücküberführt, mit 16 und 16' sind die Rückstellfedern bezeichnet, die die Klemm- und Schneidelemente 21, 21' und 22, 22' in ihre Ausgangslage zurücküberführen. Der begrenzte Abzug der angeschnittenen Isolierung 311' von der Litze 31 resultiert aus der Einschubtiefe des abzuisolierenden Leiters in die Zange, definiert durch den von einem Überstand der Klemmbacke 21' ausgehenden Anschlag 23. Der das synchrone Verschwenken der korrespondierenden Schneidbacken und damit dann auch der korrespondierenden Klemmbacken sicherstellende, aus der Schneidbacke 22' vorspringende, in Wechselwirkung mit der Schneidbacke 22 tretende Mitnehmer 24 dient dann auch der Führung beim Einführen des abzuisolierenden Leiters in das Zangenmaul.The pliers-like tool, shown as a whole in FIGS. 1, 3 and 5, consists, in a manner known per se, of the legs 12 and 13 combined by the axis 11, of which the leg 13 passes through the leg 12, the projections of which extend beyond the axis 11, the pliers jaws 121 and 131, with the clamping and cutting elements 21, 21 'and 22, 22' are provided with which the first stage of stripping the conductor end to be provided with a ferrule is carried out in such a way that that in the direction of the arrow A in FIGS. 1 and 12, insulated (311) stranded conductors 31 inserted into the tool when the pliers are actuated, on the one hand fixed between the clamping elements 21, 21 'and on the other hand the insulation 311 is cut by the cutting elements 22, 22' and the cut insulation 311 'then by opposing displacement of the clamping and cutting elements 21, 21' and 22, 22 'in the sense of the double arrow B in Figure 12 on the before the Ansc The end region 31 'of the strand 31 is withdrawn to a limited extent (arrow C in FIG. 12), limited because the direct action of the twist elements on the strand to be twisted is to be avoided is. With 14 a return spring is designated, which transfers the pliers legs back to their starting position, with 16 and 16 'the return springs are referred, which transfer the clamping and cutting elements 21, 21' and 22, 22 'back to their starting position. The limited removal of the cut insulation 311 'from the strand 31 results from the insertion depth of the conductor to be stripped into the pliers, defined by the stop 23 starting from a protrusion of the clamping jaw 21'. The synchronous pivoting of the corresponding cutting jaws and thus also the corresponding one Clamping jaws, which protrude from the cutting jaw 22 ′ and interact with the cutting jaw 22, then also serve as a guide when the conductor to be stripped is inserted into the pliers mouth.

Sie besteht aus den an der Stirnseite der Zangenbacken 121 und 131 von beiden Backen ausgehenden, jeweils auf die andere Backe orientierten Stegen 41 und 42, die sich in zueinander versetzten Ebenen verlaufend beim Schließen der Zange unter Belassung eines Zwischenraums übereinander schieben (insbes. Figuren 13 und 14). Von den entsprechend der Bewegungskurve der Zangenbacken einen bogenförmigen Verlauf nehmenden Stegen weist der Steg 42 einen geringfügigen Überstand 43 auf, der aufgeweitet den Zwischenraum 44 (Figur 14) zwischen den Stegen definiert. Zur Definition des Zwischenraumes 44 trägt weitergehend ein noch vom Zangenschenkel 121 ausgehender im Abstand vom Steg 41 verlaufender Steg 46 bei, zwischen dem und dem Steg 41 sich der vom Zangenschenkel 131 ausgehende Steg 42 führt. Eine dem aufgeweiteten Überstand 43 des Steges 42 vorgelagerte Kehle 47 dient der Lageorientierung des anzusetzenden zu verdrillenden Leiterendes. Eine schräge Auflaufkante 48 am vom Zangenschenkel 121 ausgehenden Steg 41 stellt das Greifen der Drillvorichtung sicher.Upstream of the stripping area is the drill device designed according to the invention. It consists of the webs 41 and 42, which extend from the two jaws at the end of the jaws 121 and 131 and which are oriented towards the other jaw and slide in mutually offset planes when the pliers are closed, leaving one space above the other (in particular FIGS. 13 and 14). The web 42 has a slight protrusion 43 from the webs which take an arc-shaped course in accordance with the movement curve of the jaws of the pliers, which, when widened, defines the intermediate space 44 (FIG. 14) between the webs. A further contributing factor to the definition of the intermediate space 44 is a web 46 extending from the pliers limb 121 and extending at a distance from the web 41, between which and the web 41 the web 42 starting from the pliers limb 131 leads. A throat 47 located in front of the widened protrusion 43 of the web 42 serves to position the end of the conductor to be twisted to be attached. An inclined leading edge 48 on the web 41 extending from the pliers limb 121 ensures that the drilling device is gripped.

Der Drillvorgang selbst wird zumindest unterstützt durch in die Stege eingelassene Sägeblattabschnitte 49. Die aus den Stegen 41 und 42 vorspringenden Sägeblattabschnitte 48 stellen dann auch das mit dem fortschreitenden Verdrillen des Aderende 31' einhergehende vollständige Abziehen der abgetrennten, zunächst nur abgezogenen Isolierung 311' vom verdrillten Litzenende 31' sicher.The drilling process itself is at least supported by saw blade sections 49 embedded in the webs. The saw blade sections 48 projecting from the webs 41 and 42 then also represent the complete removal of the separated, initially only removed insulation 311 'from the twisted one, which is associated with the progressive twisting of the wire end 31' Strand end 31 'sure.

Integriert ist in die Zange eine im Detail insbes. aus den Figuren 6 bis 9 entnehmbare Crimpvorrichtung zum Ansetzen der Aderendhülse an die freigelegte, vorweg verdrillte Litze des Leiters. Die eigentliche Crimpvorrichtung (Figur 6 und 7) besteht aus einer den anstellbaren Zangenschenkel 13 im Kreuzungsbereich der Zangenschenkel 12 und 13 durchsetzende, auf der die Zangenschenkel zusammenfassenden Achse 11 verschwenkbar gelagerten Kassette 61, in der eine Kulisse 62 mit Überstand 63 über den Zangenschenkel 12 ausgebildet ist, in dem ein senkrecht zur Zeichnungsebene zugängliches Gesenk 631 ausgebildet ist, in dem die am verdrillten Litzenende 31' angesetzte Aderendhülse 761 gegenüber dem Litzenende 31' mit Hilfe eines sich in der Kulisse 62 führende Preßstempel 64 verpreßt wird, der über einen mit ihm in Wechselwirkung stehende, gegenüber der die Zangenschenkel 12 und 13 zusammenfassenden Achse 11 fixierten Hebel 66 in Richtung auf das Gesenk 631 und gegenläufig dazu verlagerbar ist. Der das Gesenk 631 ausbildende Überstand 63 der Kulisse 62 weist seinerseits einen in der Zeichnungsebene vorspringenden, das freie Ende des Aderendhülsengurts 76 (Figur 4) aufnehmenden, ebenfalls senkrecht zur Zeichnungsebene zugänglichen Eingang 632 auf. An dem Überstand 63 der Kulisse 62 ist des weiteren eine Stellschraube 65 zur Anpassung des darin ausgebildeten Gesenks 631 an die jeweilige Aderendhülsenabmessung angesetzt. Beaufschlagt wird das Gesenk 631 zum Verpressen der Aderendhülse 761 auf dem verdrillten Litzenende 31' von einem an dem anstellbaren Zangenschenkel 13 lösbar gelagerten Magazin 71 für einen Aderendhülsengurt 76, dessen Mündung 72 auf den Eingang 632 zum Gesenk 631 orientiert ist. Überführt wird die vorderste, noch Bestandteil des Aderendhülsengurts 76 bildende Aderendhülse 761 in das Gesenk 631 mit Hilfe des Leiters 31, dessen freigelegtes, verdrilltes Litzenende 31' senkrecht zur Zeichnungsebene in die Aderendhülse 761 eingeführt und der Leiter 31 sodann die Aderendhülse 761 in das Gesenk 631 überführend in der Zeichnungsebene in Richtung auf das Gesenk 631 verlagert wird. Befindet sich die Aderendhülse 761 mit dem darin befindlichen verdrillten Litzenende 31' im Gesenk 631, wird die Zange betätigt, wobei unter der Einwirkung des Hebels 66 die Verlagerung des Preßstempels 64 in das Gesenk 631 erfolgt, unter dessen Einwirkung die Aderendhülse 761 auf den verdrillten Litzenende 31' verpreßt wird. Vorweg wird die im Gesenk 631 befindliche Aderendhülse 761 vom Aderendhülsengurt 76 durch ein den Gurt 762 durchtrennendes Messer 681 abgetrennt, das einem sich in einer weiteren oberhalb der Kulisse 62 für den Preßstempel 64 in der Kassette 61 verlaufenden Kulisse 67 führenden Messerträger 68 vor Kopf zugeordnet ist, der über einen am stationären Zangenschenkel 12, d.h. an dessen Backe 121, angelenkten Kniehebeltrieb 69 in Richtung auf das Gesenk 631, und gegenläufig dazu verlagerbar ist (Figuren 8 und 9). Der an der Backe 121 des Zangenschenkels 12 gelagerte Kniehebeltrieb 69 stellt sicher, daß das Messer 681 vor dem Auflaufen des Preßstempels 64 gegen die in dem Gesenk 631 befindliche Aderendhülse 761 mit dem Aderendhülsengurt 76, den Gurt 762 durchtrennend in Eingriff gelangt und die Aderendhülse 761 vorweg vom Gurt 762 abtrennt.Integrated into the pliers is a crimping device, which can be seen in detail from FIGS. 6 to 9, for attaching the ferrule to the exposed, previously twisted strand of the conductor. The actual crimping device (FIGS. 6 and 7) consists of a cassette 61 which passes through the adjustable pliers limbs 13 in the crossing area of the pliers limbs 12 and 13 and on which axis 11 which summarizes the pliers limbs and in which a link 62 with a projection 63 over the pliers limb 12 is formed is formed in a die 631 which is accessible perpendicularly to the plane of the drawing, in which the wire end sleeve 761 attached to the twisted strand end 31 'is pressed against the strand end 31' by means of a press ram 64 which is guided in the link 62 and which is pressed into it with a Interacting lever 66, which is fixed with respect to the axis 11 which summarizes the pliers legs 12 and 13, can be displaced in the direction of the die 631 and in the opposite direction. The protrusion 63 of the link 62 which forms the die 631 in turn has an entrance 632 which projects in the plane of the drawing and receives the free end of the ferrule strap 76 (FIG. 4) and is also accessible perpendicular to the plane of the drawing. A set screw 65 for adapting the die 631 formed therein to the respective ferrule dimension is also attached to the projection 63 of the link 62. The die 631 is pressurized for pressing the wire end sleeve 761 on the twisted strand end 31 'by a detachably mounted on the adjustable pliers leg 13 Magazine 71 for a wire end ferrule belt 76, the mouth 72 of which is oriented towards the entrance 632 to the die 631. The foremost wire end sleeve 761, which still forms part of the wire end sleeve belt 76, is transferred into the die 631 with the aid of the conductor 31, the exposed, twisted strand end 31 'of which is inserted into the wire end sleeve 761 perpendicular to the plane of the drawing and the conductor 31 then the wire end sleeve 761 into the die 631 is transferred in the drawing plane in the direction of the die 631. If the wire end sleeve 761 with the twisted strand end 31 'located therein is in the die 631, the pliers are actuated, under the action of the lever 66 the press ram 64 is displaced into the die 631, under whose action the wire end sleeve 761 on the twisted strand end 31 'is pressed. First of all, the wire end sleeve 761 located in the die 631 is separated from the wire end sleeve belt 76 by a knife 681 which cuts through the belt 762 and which is assigned in front of the head a knife carrier 68 which extends in a further link 67 running above the link 62 for the press ram 64 in the cassette 61 which is displaceable via a toggle lever drive 69 articulated on the stationary pliers leg 12, ie on its jaw 121, in the direction of the die 631 and in the opposite direction (FIGS. 8 and 9). The toggle lever drive 69 mounted on the jaw 121 of the pliers arm 12 ensures that the knife 681, before the press ram 64 comes up against the wire end sleeve 761 located in the die 631, engages with the wire end sleeve belt 76, the belt 762 and the wire end sleeve 761 in advance detach from belt 762.

In Komplettierung des Werkzeugs durch eine Ablängstation für den mit dem Werkzeug zu bearbeitenden Leiter 31 ist in der Kassette 61 dann auch noch eine weitere, zu den Kulissen 62 und 67 gegenläufige Kulisse 81 mit einem über die andere Schmalseite des anstellbaren Zangenschenkels 12 vorspringenden Überstand 82 vorgesehen, wobei in dem Überstand 82 eine Aufnahme 821 ausgebildet ist, in die bei darin eingelegtem Leiter 31 beim Schließen der Zange ein den Leiter 31 ablängendes, vor Kopf eines sich in der Kulisse 81 führenden Messerträgers 83 angesetztes Messer 831 unter der Einwirkung des zweiarmigen, die die Zangenschenkel 12 und 13 zusammenfassende Achse 11 durchsetzenden Hebels 66 auf den Messerträger 83 in Richtung auf die Ablängenaufnahme 821 verlagerbar und aus der Schneidlage dann auch wieder zurück verlagerbar ist. Die Zurückverlagerung sowohl des Preßstempels 64 als auch des Messerträgers 83 in die jeweilige Ausgangslage wird bewirkt durch die im übrigen dann auch die Überführung der Zange aus der Schließstellung in die Öffnungsstellung bewirkende Rückstellfeder 14, die an dem Hebel 66 angreift.In completing the tool by means of a cutting station for the conductor 31 to be machined with the tool, there is also a further link 81 in the cassette 61 which is opposite to the links 62 and 67 and which projects over the other narrow side of the adjustable pliers leg 12 Protrusion 82 is provided, a protrusion 821 being formed in the protrusion 82, into which, with the conductor 31 inserted therein, when the pliers are closed, a knife 831 which cuts the conductor 31 to length and is placed in front of a knife carrier 83 leading in the link 81 under the action of the two-armed lever 66, which passes through the pincer legs 12 and 13 and which passes through axis 11, can be displaced onto the knife carrier 83 in the direction of the cut-off receptacle 821 and can then also be moved back out of the cutting position. The return of both the press ram 64 and the knife carrier 83 into the respective starting position is brought about by the restoring spring 14 which then also brings about the transfer of the pliers from the closed position into the open position and acts on the lever 66.

Der Arbeitsablauf, was die zunächst teilweise Abisolierung des Leiterendes und was das Verdrillen der von einer Litze gebildeten Ader in ihrem mit einer Aderendhülse zu versehenden Endbereich betrifft, ist aus den Figuren 12 bis 14 zu entnehmen, ohne daß es insoweit weitergehender Erläuterungen bedarf.The work sequence, which relates to the partial partial stripping of the conductor end and to the twisting of the wire formed by a strand in its end region to be provided with a wire end sleeve, can be seen from FIGS. 12 to 14, without further explanations being required in this regard.
