Description

Die Erfindung bezieht sich auf ein Anschlußwerkzeug zum Anschließen von ankommenden und abgehenden Leitern an Kontaktelemente in Anschlußmodulen entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a connection tool for connecting incoming and outgoing conductors to contact elements in connection modules according to the preamble of claim 1.

In der DE 43 33 263 C2 wird bereits ein Anschlußwerkzeug beschrieben, welches einen ergonomisch geformten Handgriff mit einem doppel-T-förmigen Werkzeugkopf mit einem Schlitz im Mittelsteg aufweist. Mittels des Werkzeugkopfes wird ein Leiter in den Kontaktschlitz eines Schneid-Klemm-Kontaktelementes eingedrückt, wobei das Schneid-Klemm-Kontaktelement in den Schlitz eingreift, so daß der Werkzeugkopf den Leiter beidseits des blattförmigen Schneid-Klemm-Kontaktelementes angreifen und in den Kontaktschlitz eindrücken kann. Dabei wird mittels der scharfkantigen Schneiden der Kontaktschenkel die Isolierung des Leiters eingeschnitten und der metallische Leiter mit dem Schneid-Klemm-Kontaktelement elektrisch kontaktiert.DE 43 33 263 C2 already describes a connection tool which has an ergonomically shaped handle with a double-T-shaped tool head with a slot in the central web. By means of the tool head, a conductor is pressed into the contact slot of an insulation displacement contact element, the insulation displacement contact element engaging in the slot, so that the tool head can engage the conductor on both sides of the sheet-shaped insulation displacement contact element and press it into the contact slot . The insulation of the conductor is cut in by means of the sharp-edged cutting edges of the contact legs and the metallic conductor is electrically contacted with the insulation displacement contact element.

Dieses bekannte Werkzeug ist für den Anschluß von kleineren Drahtdurchmessern an Schneid-Klemm-Kontaktelementen geeignet und kann nicht immer ausreichend in eine bequeme Handhabungsstellung gebracht werden.This known tool is suitable for the connection of smaller wire diameters to insulation displacement contact elements and cannot always be sufficiently brought into a convenient handling position.

In der EP 0 040 307 B1 wird ein Werkzeug zum elektrischen Anschließen von isolierten Leiterdrähten beschrieben, in dem ein Schlagmechanismus und ein gegen Federkraft längsverschiebbarer Stößel angeordnet sind. Der Stößelkopf ragt stirnseitig aus dem Handgriff heraus und dient zum Quereindrücken des Leiterendes in den Kontaktschlitz. Der Stößelkopf weist des weiteren einen Drahtschneider zum Abschneiden des Leiterdrahtes nach dem Eindrücken auf.EP 0 040 307 B1 describes a tool for the electrical connection of insulated conductor wires, in which a striking mechanism and a plunger which can be displaced longitudinally against spring force are arranged. The plunger head protrudes from the front of the handle and is used to push the end of the conductor into the contact slot. The plunger head also has a wire cutter for cutting off the conductor wire after being pressed in.

Nachteilig ist es, daß nur relativ kleine Drahtdurchmesser in Schneid-Klemm-Anschlußkontakte der in der Fernmelde- und Datentechnik verwendeten Schneid-Klemm-Anschlußtechnik eingedrückt und danach abgeschnitten werden können. Das Beschalten von Anschlußmodulen für größere Strom- und Spannungsbelastbarkeit ist aufgrund der notwendig werdenden höheren Kontaktierungskräfte nicht möglich.It is disadvantageous that only relatively small wire diameters in insulation displacement terminals of the insulation displacement connection technology used in telecommunications and data technology can be pressed in and then cut off. It is not possible to connect connection modules for greater current and voltage loads due to the higher contacting forces that are required.

Aufgabe der Erfindung ist es, ein multifunktionelles Anschlußwerkzeug zu entwickeln, mit dem ein bequemes und zuverlässiges Anschließen und Lösen von Kabeladern für eine große Bandbreite von Drahtdurchmessern in Anschlußmodulen gewährleistet sind.The object of the invention is to develop a multifunctional connection tool with which a convenient and reliable connection and disconnection of cable cores for a wide range of wire diameters in connection modules are guaranteed.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß durch eine vordere Öffnung des Gehäusegriffes eine kombinierte Schneide- und Eindrückvorrichtung, bestehend aus einer Druckschraube mit Federn, aus einem Messerträger mit Messern, aus einem Nockengehäuse, eingebracht ist, und daß eine Abdeckung vorgesehen ist, die bei Betätigung der Schneide- und Eindrückvorrichtung auf dem Gehäusegriff gleitet.To achieve this object, the invention provides that a combined cutting and pressing device, consisting of a pressure screw with springs, a knife holder with knives, a cam housing, is introduced through a front opening of the housing handle, and that a cover is provided, which slides on the housing handle when the cutting and pressing device is actuated.

Die Abdeckung mit der Schneide- und Eindrückvorrichtung ist in vier Raststellungen auf dem Gehäusegriff arretierbar, so daß für jede Anschlußsituation eine bequeme Handhabung des Anschlußwerkzeuges gewährleistet ist.The cover with the cutting and pressing device can be locked in four latching positions on the housing handle, so that the connection tool is easy to handle for every connection situation.

Die Nockensteuerung ermöglicht es, mit geringem Kraftaufwand Kabel mit großem Leiterdurchmesser mühelos abzuschneiden und danach in den Kontaktschlitz des Anschlußmoduls einzudrücken. Die dafür benötigte Kraft ist nicht größer als für ein Eindrücken des Kabels in den Kontaktschlitz.The cam control makes it easy to cut cables with a large conductor diameter with little effort and then press them into the contact slot of the connection module. The one you need The force is not greater than for pushing the cable into the contact slot.

Das Anschlußwerkzeug ist einfach und robust aufgebaut und leicht montierbar.The connection tool is simple and robust and easy to assemble.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention result from the subclaims.

Entsprechend der Darstellung in der Fig. 1 besteht das Anschlußwerkzeug im wesentlichen aus einem einteiligen Gehäusegriff 1, einer Abdeckung 2, einem Werkzeugkopf 23, bestehend aus einem Messerträger 3, einem Nockengehäuse 4, aus zwei Messern 5, einem Druckstab 6, aus Federn 7,8,9, aus Sicherungsringen 10,11, und aus einer aus dem Gehäusegriff 1 herausschwenkbaren Drahtdurchmessermeß- und Drahtlösevorrichtung 12, einem Stift 13 und einem Splint 14.According to the representation in Fig. 1, the connecting tool consists essentially of a one-piece Housing handle 1, a cover 2, a tool head 23, consisting of a knife carrier 3, a cam housing 4, two knives 5, a pressure rod 6, springs 7, 8, 9, locking rings 10, 11, and one from the housing handle 1 swiveling out wire diameter measuring and release device 12, a pin 13 and a split pin 14th

Das Anschlußwerkzeug ist zum Anschließen von Kupferkabeln bis zu 2,5 mm2 Querschnitt bzw. von Leiterdurchmessern von 1,8 mm oder Kabeldurchmesser von 3,8 mm in Anschlußmodulen bis zu 1000 V geeignet.The connection tool is suitable for connecting copper cables with a cross section of up to 2.5 mm 2 or with conductor diameters of 1.8 mm or cable diameters of 3.8 mm in connection modules up to 1000 V.

Der Anschluß- und Kabeltrennvorgang erfolgt in umgekehrter Reihenfolge zum Vorgang mit den bekannten Anschlußwerkzeugen für die Schneid-Klemm-Anschlußtechnik (Anlegewerkzeug nach EP 0 040 307 B1).The connection and cable disconnection process takes place in the reverse order to the process with the known connection tools for the insulation displacement connection technology (application tool according to EP 0 040 307 B1).

Das anzuschließende Kabel wird auf den Kontakt des nicht dargestellten Anschlußmoduls gelegt, wo er durch Vorfixierungsmittel (Klemmrippen) arretiert wird. Dann wird das Anschlußwerkzeug auf diese Kabel-Position gebracht und niedergedrückt. Das Kabel wird dabei zuerst auf Länge abgeschnitten und erst danach vollkommen in den Kontaktschlitz hineingedrückt. Das abgeschnittene Kabelende ist nach dem Eindrücken abgedeckt und nicht mehr zugänglich.The cable to be connected is placed on the contact of the connection module, not shown, where it is locked by pre-fixing means (clamping ribs). Then the connection tool is brought to this cable position and pressed down. The cable is first cut to length and only then pushed completely into the contact slot. The cut cable end is covered after being pressed in and is no longer accessible.

Das Werkzeug ist handlich ausgeformt und erfordert für den Abschneidevorgang von starken Kabeln nicht mehr Kraftaufwand als für ein alleiniges Eindrücken. Die Reduzierung des Kraftaufwandes wird durch die angewendete Nockensteuerung mittels des Nockengehäuses 4 (Fig. 11, 12) erreicht.The tool is designed to be handy and requires no more effort to cut strong cables than to press it in alone. The reduction in effort is due to the applied Cam control achieved by means of the cam housing 4 (Fig. 11, 12).

Die gesamte Schneide-/Eindrückvorrichtung des Werkzeuges, der Werkzeugkopf 23, bestehend im wesentlichen aus dem Nockengehäuse 4, der Feder 9, aus dem Messerträger 3 mit den Messern 5, in dessen durchgehender Bohrung der Druckstab 6 mit der Feder 7 geführt ist, und dem Sicherungsring 11, aus dem Stift 13 und der Feder 8, ist von vorne durch eine kreisrunde Öffnung 17 des Gehäusegriffs 1 (Fig. 3,4) eingesetzt und ist innen an der Stelle 19 (Fig. 3) durch den Splint 14 (Fig. 1,2,4) am Gehäusegriff 1 gesichert. Die Abdeckung 2 ist in den Gehäusegriff 1 über Rastelemente 15 der Abdeckung 2 in Nuten 20 des Gehäusegriffes 1 eingerastet (Fig. 1a,4).The entire cutting / pressing device of the tool, the tool head 23, consisting essentially of the cam housing 4, the spring 9, the knife holder 3 with the knives 5, in the through bore of which the pressure rod 6 is guided with the spring 7, and the Circlip 11, made of pin 13 and spring 8, is inserted from the front through a circular opening 17 in housing handle 1 (FIGS. 3, 4) and is inside at position 19 (FIG. 3) through split pin 14 (FIG. 1,2,4) secured on the handle 1. The cover 2 is snapped into the housing handle 1 via latching elements 15 of the cover 2 in grooves 20 of the housing handle 1 (FIGS. 1a, 4).

Die Abdeckung 2 (Fig. 5,6) weist vier axiale Rippen 18 auf, die eine Drehung des Werkzeugkopfes 23 jeweils um 90° gegenüber dem Gehäusegriff 1 in vier Raststellungen erlauben, so daß eine Anlage der Schneide-/Eindrückvorrichtung an den zu beschaltenden Kontakt so erfolgen kann, wie es für eine zuverlässige Handhabung des Werkzeuges am bequemsten ist. Die Abdeckung 2 gleitet achsial am Gehäusegriff 1 so weit entlang, wie das Werkzeug betätigt wird (Fig. 2).The cover 2 (Fig. 5,6) has four axial ribs 18, which allow rotation of the tool head 23 in each case by 90 ° with respect to the housing handle 1 in four latching positions, so that the cutting / pushing device comes into contact with the contact to be connected can be done as it is most convenient for reliable tool handling. The cover 2 slides axially along the housing handle 1 as far as the tool is actuated (FIG. 2).

Das Anschaltwerkzeug arbeitet entsprechend der Darstellung in der Fig. 2 wie folgt:The connection tool operates as follows in accordance with the illustration in FIG. 2:

Die Messer 5 mit der Messerschneide 30 und dem Messerschaft 28 (Fig. 9,10) sind auf dem Messerträger 3 (Fig. 7,8) um den Drehpunkt 21 des Stiftes 13 mit der Feder 9 montiert (Fig. 1,9) und gleiten über das Nockengehäuse 4, wenn das Werkzeug auf den anzuschaltenden Draht gedrückt wird, um ihn auf Länge zu schneiden. Der Messerträger 3 gleitet entlang der Innenseite 22 des Nockengehäuses 4 (Fig. 11) bis der Draht abgeschnitten ist. Das Nockengehäuse 4 ist über den Messerträger 3 geschoben.The knives 5 with the knife edge 30 and the knife shaft 28 (FIGS. 9, 10) are on the knife holder 3 (Fig. 7,8) mounted around the pivot point 21 of the pin 13 with the spring 9 (Fig. 1,9) and slide over the cam housing 4 when the tool is pressed onto the wire to be switched on to cut it to length . The knife carrier 3 slides along the inside 22 of the cam housing 4 (FIG. 11) until the wire is cut off. The cam housing 4 is pushed over the knife carrier 3.

Das Nockengehäuse 4 besteht gemäß der Darstellung in den Fig. 11,12 aus einem zylinderförmigen Hohlkörper 33 mit einer Nut 35 und mit Führungs- bzw. Spreizflächen 29 zur Führung der Messerschäfte 28. In der hinteren Hälfte des Nockengehäuses 4 ist innen eine abgeflachte Bohrung 34 zur Halterung der Druckfeder 8 vorgesehen (Fig. 12).As shown in FIGS. 11, 12, the cam housing 4 consists of a cylindrical hollow body 33 with a groove 35 and with guide or spreading surfaces 29 for guiding the knife shanks 28. In the rear half of the cam housing 4 there is a flattened bore 34 on the inside provided for holding the compression spring 8 (Fig. 12).

Der vormontierte Messerträger 3 ist in das Nockengehäuse 4 eingeführt und wird mittels Sicherungsring 10 am Nockengehäuse 4 festgelegt.The preassembled knife carrier 3 is inserted into the cam housing 4 and is fixed on the cam housing 4 by means of a locking ring 10.

Der Druckstab 6 gleitet innerhalb des Messerträgers 3 weiter zurück bis zu der Stelle, an welcher er gegen die Rückwand 32 des Gehäusegriffs 1 zur Ruhe kommt (Fig. 1,2) und drückt den Draht bis zum Boden in den Kontaktschlitz des Anschluß-Moduls. Wenn der Draht in den Kontaktschlitz eingedrückt ist und kein Druck mehr ausgeübt wird, dann zieht sich der gesamte Mechanismus durch die Kraft der Federn 7,8,9 in die Ausgangsstellung zurück (Fig. 1). Die Druckfeder 7 ist auf den Druckstab 6 aufgeschoben und mittels Sicherungsring 11 festgelegt.The pressure rod 6 slides further inside the knife carrier 3 back to the point at which it comes to rest against the rear wall 32 of the housing handle 1 (FIG. 1, 2) and presses the wire to the bottom into the contact slot of the connection module. When the wire is pressed into the contact slot and no more pressure is exerted, the entire mechanism is retracted into the starting position by the force of the springs 7, 8, 9 (FIG. 1). The compression spring 7 is pushed onto the compression rod 6 and fixed by means of the locking ring 11.

Beim Niederdrücken stützt sich das Werkzeug mit dem Kopfstück 27 des Druckstabes 6 (Fig. 13) auf dem Anschlußmodul ab, die Messerschäfte 28 (Fig.10) gleiten an den schrägen, keilförmigen Führungs- bzw. Spreizflächen 29 des Nockengehäuses 4 so entlang, daß sich die Messerschneiden 30 (Fig. 10) scherenförmig schließen und den Draht seitlich am Kontaktschlitz des Anschlußmoduls abschneiden. Die Feder 9 sorgt dafür, daß die Schneiden 30 der Messer 5 nach einem Beschaltungsvorgang wieder in die Ausgangslage zurückgeführt werden. Die Scherbewegung der Messerschneiden 30 erfolgt um den durch den Stift 13 gebildeten Drehpunkt 21.When depressed, the tool is supported with the head piece 27 of the pressure rod 6 (FIG. 13) on the connection module, the knife shafts 28 (FIG. 10) slide along the oblique, wedge-shaped guide or spreading surfaces 29 of the cam housing 4 so that the knife edges 30 (Fig. 10) close like scissors and cut the wire on the side of the contact slot of the connection module.
