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 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 Figures 1, 3 and 5, consists in itself
known manner from those summarized by the
Vorgelagert ist dem Abisolierbereich die erfindungsgemäß
ausgelegte Drillvorrichtung. 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 Zangenbakken
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. The stripping area is preceded by the invention
designed drill. It consists of the other
Face of the
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 in
the webs embedded saw
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.
