Description

Die Erfindung bezieht sich auf ein Verfahren zum Anschließen von Kabeladern gemäß dem Oberbegriff des Anspruches 1 sowie auf eine.Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for connecting cable wires according to the preamble of claim 1 and to one . Device for performing the method.

Aus der DE-PS 26 10 461 sind Anschlußleisten mit Schneid-/Klemm-Anschlußkontakten vorbekannt, die aus zwei, einen offenen Längsschlitz begrenzenden Kontaktzungen aus dünnem Federblech gebildet sind. Beim Eindrücken der Kabelader in den Kontaktschlitz wird durch die relativ scharfen Kanten der Federzungen zuerst die Isolierstoffhülle der Kabelader zerschnitten. Anschließend dringen die Kanten um einen gewissen Betrag in das Material des Innenleiters der Kabelader ein, um den gewünschten elektrisch leitenden Kontakt herzustellen.From DE-PS 26 10 461 terminal strips with insulation displacement contacts are known, which are formed from two, an open longitudinal slot delimiting contact tongues made of thin spring steel. When the cable core is pressed into the contact slot, the insulating sleeve of the cable core is first cut through the relatively sharp edges of the spring tongues. The edges then penetrate a certain amount into the material of the inner conductor of the cable core in order to produce the desired electrically conductive contact.

Zum Eindrücken der isolierten Kabelader in den Kontaktschlitz und zum Herausziehen einer eingedrückten Kabelader aus dem Kontaktschlitz ist ein spezielles Werkzeug aus dem DE-GM 80 13 494 vorbekannt. Mit diesem bekannten Werkzeug lassen sich allerdings nur Kabeladern mit kleinem Kabelquerschnitt an Schneid-/Klemm-Anschlußkontakte anschließen. Für das Anschließen von Kabeladern mit einer im Verhältnis zum Aderquerschnitt dicken Isolierstoffhülle, wie z.B. Kabeladern der Starkstromtechnik oder Kabeladern von Fernmelde-Freileitungen, sogenannte Dropwire-Kabel, werden bisher üblicherweise Schraub-/Klemm-Anschl'ußkontakte eingesetzt. Diese erfordern ein Abisolieren der Kabeladern und aufwendige Schraubarbeiten.A special tool from DE-GM 80 13 494 is known for pressing the insulated cable core into the contact slot and for pulling out a pressed cable core from the contact slot. With this known tool, however, only cable cores with a small cable cross section can be connected to cutting / clamping connection contacts shut down. For the connection of cable cores with an insulating sleeve that is thick in relation to the core cross section, such as cable cores of high-voltage technology or cable cores of telecommunication overhead lines, so-called drop wire cables, screw / clamp connection contacts have been used up to now. These require stripping the cable wires and complex screwing work.

Es ist jedoch aus der DE-PS 32 14 896 bereits ein Schneid-/Klemm-Anschlußkontakt vorbekannt, der das abisolierfreie Anschließen von Drähten unterschiedlicher Außen- und Innenleiterdurchmesser und unterschiedlicher Isolationsmaterialien erlaubt. Ein derartiger Schneid-/Klemm-Kontakt wird in Anschlußleisten gemäß DE-OS 34 15 396 eingesetzt. Beim-Eindrücken von Kabeladern mit einer im Verhältnis zum Aderquerschnitt dicken Isolierstoffhülle in diese Schneid-/Klemm-Anschlußkontakte treten allerdings hohe Eindrückkräfte auf, die mit dem bisher bekannten Anlegewerkzeug nicht immer bewältigt werden können.However, it is already known from DE-PS 32 14 896 a cutting / clamping connection contact that allows the stripping-free connection of wires of different outer and inner conductor diameters and different insulation materials. Such an insulation displacement contact is used in connection strips according to DE-OS 34 15 396. When cable cores with an insulating sleeve thick in relation to the wire cross-section are pressed into these cutting / clamping connection contacts, however, high insertion forces occur which cannot be always managed with the previously known contact tool.

Der Erfindung liegt von daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Anschließen von Kabeladern mit einer im Verhältnis zum Aderquerschnitt dicken Isolierstoffhülle an Schneid-/ Klemm-Anschlußkontakte zu schaffen, wobei die beim Eindrücken der dicken Kabelader in die Schneid-/ Klemm-Anschlußkontakte auftretenden Eindrückkräfte verringert sind.The invention is therefore based on the object of providing a method and a device for connecting cable cores with an insulating sleeve which is thick in relation to the core cross section to cutting / clamping connection contacts, the contact being made when the thick cable core is pressed into the cutting / clamping Contact forces occurring are reduced.

Die Lösung dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Anspruches 1 für das Verfahren und des Anspruches 3 für die Vorrichtung. Durch vor dem Eindrückvorgang erfolgendes, mindestens teilweises Wegschneiden der Isolierstoffhülle der Kabelader im vorgesehenen Kontaktierungsbereich können die beim Eindrücken der dicken Kabelader in die Schneid-/Klemm-Anschlußkontakte auftretenden Eindrückkräfte erheblich verringert werden, insbesondere dann, wenn im Kontaktierungsbereich für die Kontaktschenkel des Schneid-/ Klemm-Anschlußkontaktes zwei einander gegenüberliegende Teile aus der Isolierstoffhülle der dicken Kabelader weggeschnitten werden. Dies erfolgt bei der erfindungsgemäßen Vorrichtung durch eine Vorschneideeinrichtung mit zwei bogenförmigen Schneidemessern. Beim Anschaltevorgang, d.h. beim Eindrücken des erfindungsgemäß ausgebildeten Kontaktierungsbereichs der Kabelader in den Kontaktschlitz des Schneid-/Klemm-Anschlußkontaktes müssen die Schneidkanten des Kontaktschlitzes weniger Isolierstoffmaterial durchdringen, so daß die Eindrückkräfte erheblich verringert werden. Beschädigungen der Federzungen des Anschlußkontaktes sind somit nicht mehr zu befürchten.The solution to this problem results from the characterizing features of claim 1 for the method and claim 3 for the device. By at least partially cutting away the insulating sheath of the cable core in the intended contacting area before the pressing-in process, the pressing-in forces that occur when the thick cable core is pressed into the cutting / clamping connection contacts can be considerably reduced, in particular if the contacting area of the cutting / Clamp connection contact two opposite parts are cut away from the insulating sleeve of the thick cable core. In the device according to the invention, this is done by a pre-cutting device with two arcuate cutting knives. When switching on, i.e. when pressing the contact area of the cable core designed according to the invention into the contact slot of the cutting / clamping connection contact, the cutting edges of the contact slot have to penetrate less insulating material, so that the pressing forces are considerably reduced. Damage to the spring tongues of the connection contact is therefore no longer to be feared.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den weiteren Unteransprüchen. Hierbei ist noch zu berücksichtigen, daß die erfindungsgemäße Vorrichtung sowohl an Anschlußleisten selbst angebracht als auch als Handwerkzeug in Form eines sogenannten Anlegewerkzeuges ausgebildet sein kann.Further advantageous embodiments of the invention result from the further subclaims. It should also be taken into account here that the device according to the invention can be attached to terminal strips itself or can be designed as a hand tool in the form of a so-called application tool.

Das Anlegewerkzeug besteht aus einem Schaft 14 (Basisteil)mit einem Griffteil 15 an einem Ende sowie mit einem Führungssteg 17, einem Hebel 18 und Eindrückstegen 32 am anderen Ende. Sämtliche Bauteile 14, 15, 17, 18 und 32 sind einstückig aus Kunststoff von für ein Handwerkzeug notwendiger Festigkeit hergestellt. Der bogenförmig gerundete Griffteil 15 dient zum manuellen Aufbringen einer Eindrückkraft, mit welcher die Eindrückstege 32 beaufschlagt werden können, um Kabeladern 20 mit einer im Verhältnis zum Aderquerschnitt des Innenleiters 22 dicken Isolierstoffhülle 21 in Schneid-/ Klemm-Anschlußkontakte 44 von Anschlußleisten 40 eindrücken zu können. Der Führungssteg 17 dient hierbei der Einführungssicherung der Eindrückstege 32. Der Hebel 18 dient zum Herausnehmen von in die Anschlußleiste 40 eingesteckten, nicht dargestellten Überspannungsableitermagazinen.The application tool consists of a shaft 14 (base part) with a grip part 15 at one end and with a guide web 17, a lever 18 and insertion webs 32 at the other end. All components 14, 15, 17, 18 and 32 are made in one piece from plastic of the strength required for a hand tool. The curved, rounded grip part 15 is used for the manual application of an indentation force with which the indentation webs 32 can be acted upon by cable cores 20 to be able to press an insulating sleeve 21 thick in relation to the wire cross section of the inner conductor 22 into insulation displacement contacts 44 of terminal strips 40. The guide bar 17 serves to secure the insertion of the push-in bars 32. The lever 18 is used for removing surge arrester magazines, not shown, which are inserted into the terminal block 40.

Am den Schaft 14 des Anlegewerkzeuges ist eine Vorschneideeinrichtung 11 für die dicke Kabelader 20 angebracht. Diese besteht aus einem U-förmigen Hebel 23, der in der Schwenkachse 27 angelenkt ist. Der U-förmige Hebel 23 trägt auf den Innenseiten 33 seiner beiden Seitenflächen 56, 57 je ein bogenförmiges Schneidemesser 12, 13. Diese sind unter Freilassung eines Freiraumes vom mindestens der Breite des Durchmessers des Innenleiters 22 der Kabelader 20 gegeneinander gerichtet, wie es insbesondere in Fig. 2 dargestellt ist. Die offene Seite des U-förmigen Hebels 23 ist in Richtung des Schaftes 14 angeordnet, so daß der Hebel 23 im niedergedrückten Zustand mit seinen Seitenflächen 56, 57 den Schaft 14 umschließt, wie es in Fig. 3 mit durchgezogenen Linien dargestellt ist. Aus dem Kunststoffmaterial des Schaftes 14 ist eine Führungsmulde 26 zur Aufnahme und Lagerung der Kabelader 20 ausgeformt.A pre-cutting device 11 for the thick cable core 20 is attached to the shaft 14 of the application tool. This consists of a U-shaped lever 23 which is articulated in the pivot axis 27. The U-shaped lever 23 carries on the inner sides 33 of its two side surfaces 56, 57 an arcuate cutting knife 12, 13. These are directed towards each other while leaving a free space of at least the width of the diameter of the inner conductor 22 of the cable core 20, as is particularly the case in FIG Fig. 2 is shown. The open side of the U-shaped lever 23 is arranged in the direction of the shaft 14, so that the lever 23 in the depressed state encloses the shaft 14 with its side surfaces 56, 57, as shown in FIG. 3 by solid lines. A guide trough 26 for receiving and storing the cable core 20 is formed from the plastic material of the shaft 14.

Vor dem Eindrücken einer Kabelader 20 mit im Verhältnis zum Aderquerschnitt des Innenleiters 22 dicker Isolierstoffhülle 21 in die Schneid-/ Klemm-Anschlußkontakte 44 einer Anschlußleiste 40 wird die Kabelader 20 in die Führungsmulde 26 eingelegt, wobei der Hebel 23 hochgeschwenkt ist, wie es in Fig. 3 dargestellt ist. Die Führungsmulde 26 verläuft in Längsrichtung des Schaftes 14. Durch Niederdrücken des Hebels 23 wird die Isolierstoffhülle 21 der Kabelader 20 mittels der auf den Innenseiten 33 der Seitenflächen 56, 57 des Hebels 23 angeordneten bogenförmigen Schneidemesser 12, 13 an zwei Stellen im vorgesehenen Kontaktierungsbereich 37 angeschnitten, wobei zwei Isolierstoffteile 34, 35 abgeschnitten werden, wie es in Fig. 2 dargestellt ist. Nach dem erneuten Hochschwenken des Hebels 23 wird die Kabelader 20 aus der Führungsmulde 26 herausgenommen und mit dem vorgesehenen Kontaktierungsbereich 37 in die Schneid-/Klemm-Anschlußkontakte 44 der Anschlußleiste 40 eingelegt, wobei der Kontaktierungsbereich 37 in den Kontaktschlitz 45 eingedrückt wird. Das Eindrücken erfolgt mittels der Eindrückstege 32, welche an die Form des Schneid-/KlemmAnschlußkontaktes 44 angepaßt sind. Im Mittelpunkt des kreisscheibenförmigen Griffteiles 15 ist ein Ziehhaken 24 drehbar gelagert, der mit seinem hakenartigen Ende 36 zum Herausziehen und Entfernen von fest in die Schneid-/ Klemm-Anschlußkontakte 44 eingedrückten Kabeladern 20 dient. Es ist eine Rasteinrichtung 30 für den Ziehhaken 24 vorgesehen, welche aus zwei am Griffteil 15 ausgeformten Rastnasen 29 und einer Raste 30 im Ziehhaken gebildet ist. Hierdurch kann der Ziehhaken 24 zwei Positionen einnehmen, nämlich die in Fig. 1 mit ausgezogenen Linien dargestellte Ruhestellung, bei welcher der Ziehhaken 24 parallel zum Schaft 14 liegt, und die in Fig. 1 mit gestrichelten Linien und in Fig. 4 dargestellte Arbeitsstellung, bei welcher der Ziehhaken 24 etwa rechtwinklig vom Schaft 14abgewinkelt ist. Das Griffteil 15 besitzt ferner drei Durchgangsöffnungen 19 für Kabeladern 20, welchen am Ziehhaken 24 eine Trenneinrichtung 25 zugeordnet ist. Diese besteht aus zwei bogenförmigen Ausschnitten 58, 59, die einen spitzen Zacken 39 zwischen sich bilden. Ein zweiadriges Kabel (Fig. 5) wird durch eine Durchgangsbohrung 19 hindurchgeführt, anschließend wird der Ziehhaken 24 mit seinem spitzen Zacken 39 so in den Bereich dieser Durchgangsöffnung 19 verschwenkt, daß der spitzeeZacken 39 zwischen die beiden Kabeladern 20 des zweiadrigen Kabels kommt, so daß diese beim Durchziehen durch die Durchgangsöffnung 19 vom spitzen Zacken 39 in zwei einzelne Kabeladern 20 aufgetrennt werden.Before a cable core 20 with an insulating sleeve 21 thicker than the core cross section of the inner conductor 22 is pressed into the insulation displacement contacts 44 of a terminal block 40, the cable core 20 is inserted into the guide trough 26, the lever 23 being pivoted upward, as shown in FIG 3 is shown. The guide trough 26 runs in the longitudinal direction of the shaft 14. By pressing the lever 23 down, the insulating sleeve 21 of the cable core 20 is cut at two points in the provided contacting area 37 by means of the curved cutting knives 12, 13 arranged on the inside 33 of the side surfaces 56, 57 of the lever 23 , wherein two insulating material parts 34, 35 are cut off, as shown in Fig. 2. After the lever 23 has been swiveled up again, the cable core 20 is removed from the guide trough 26 and inserted with the provided contacting area 37 into the insulation displacement contacts 44 of the terminal strip 40, the contacting area 37 being pressed into the contact slot 45. The press-in takes place by means of the press-in webs 32, which are adapted to the shape of the insulation displacement contact 44. In the center of the circular disc-shaped handle part 15, a pulling hook 24 is rotatably mounted, which, with its hook-like end 36, serves for pulling out and removing cable wires 20 that are firmly pressed into the cutting / clamping connection contacts 44. It is a locking device 30 for the Drawing hook 24 is provided, which is formed from two molded lugs 29 on the handle part 15 and a catch 30 in the drawing hook. As a result, the pulling hook 24 can assume two positions, namely the rest position shown in solid lines in FIG. 1, in which the pulling hook 24 lies parallel to the shaft 14, and the working position shown in FIG. 1 with broken lines and in FIG. 4 which of the pulling hooks 24 is angled approximately at right angles from the shaft 14. The handle part 15 also has three through openings 19 for cable cores 20, to which a separating device 25 is assigned on the pulling hook 24. This consists of two arcuate cutouts 58, 59 which form a pointed prong 39 between them. A two-core cable (Fig. 5) is passed through a through hole 19, then the pulling hook 24 with its pointed prong 39 is pivoted into the area of this through opening 19 such that the pointed prong 39 comes between the two cable cores 20 of the two-core cable, so that these are separated by pulling through the opening 19 from the pointed prongs 39 into two individual cable wires 20.
