Durch Einwirken einer Schlag- oder Hebelkraft auf das Eindrückwerkzeug (3, 20, 21) kann somit eine Dropwire-Kabelader (8) in einem einzigen Arbeitsgang an einem Schneidklemmkontakt einer Dropwire-Anschlußleiste (2) angeschlossen werden. In weiterer Ausbildung der Erfindung ist das Eindrückwerkzeug (3) als Schließstecker (20, 21) ausgebildet, der zur Festlegung dünner Kabeladern (29) in Dropwire-Anschlußleisten (2) dient.The invention relates to a device for connecting cable wires (8, 29) to insulation displacement contacts of Dropwire connection strips (2) in telecommunications technology by means of a pressing tool (3, 20, 21) provided with guide and insertion bars (9, 10) and an actuating surface ).

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Anschließen von Kabeladern an Schneidklemmkontakten von Dropwire-Anschlußleisten der Fernmeldetechnik gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device for connecting cable wires to insulation displacement contacts of Dropwire connection strips of telecommunications technology according to the preamble of claim 1.

Aus der DE 35 22 131 ist ein Eindrückwerkzeug der gattungsgemäßen Art vorbekannt. Dieses besteht aus einem Schaft mit einem Griffteil als Betäti­gungsfläche an einem Ende und mit Führungs- und Eindrückstegen am anderen Ende zum Eindrücken der Kabeladern in die Schneidklemm-Anschlußkon­takte der Dropwire-Anschlußleiste. Für Dropwire-­Kabeladern, die sehr dicke Isolierstoffhüllen aufweisen, woduch beim Eindrücken der Dropwire-­Kabeladern in die Schneidklemmkontakte der Drop­wire-Anschlußleiste hohe Eindrückkräfte entste­hen, ist am Schaft des Eindrückwerkzeuges eine Vorschneideeinrichtung angebracht, die aus einem U-förmigen Hebel und zwei an den Innenseiten seiner beiden Seitenflächen angeordneten bogen­förmigen Schneidemessern besteht. Die Dropwire-­Kabeladern werden vor dem Eindrücken in die Schneidklemmkontakte mittels der bogenförmigen Schneidemesser an zwei gegenüberliegenden Stel­len im vorgesehenen Kontaktierungsbereich ein­ geschnitten und erst nach diesem Einschneiden in die jeweiligen Schneidklemmkontakte der Dropwire-Anschluß­leiste eingelegt. Das Eindrücken erfolgt dann mit­tels der Eindrückstege, welche an die Form der Schneidklemmkontaktes angepaßt sind. Bei Verwen­dung des bekannten Eindrückwerkzeuges für Drop­wire-Kabeladern sind zwei Arbeitsschritte notwendig, um die hohen Eindrückkräfte zu verringern. Darüber hinaus ist das bekannte Eindrückwerkzeug technisch aufwendig gestaltet und somit teuer in der Her­stellung.A press-in tool of the generic type is previously known from DE 35 22 131. This consists of a shaft with a handle part as an actuating surface at one end and with guide and insertion bars at the other end for pressing the cable wires into the insulation displacement connection contacts of the Dropwire connection strip. For Dropwire cable cores that have very thick insulating sheaths, which results in high insertion forces when the Dropwire cable cores are pressed into the insulation displacement contacts of the Dropwire connection strip, a pre-cutting device is attached to the shaft of the insertion tool, which consists of a U-shaped lever and two on the inside its two side surfaces arranged arcuate cutting knives. Before being pressed into the insulation displacement contacts, the Dropwire cable cores are inserted at two opposite points in the intended contact area by means of the curved cutting blades cut and inserted into the respective insulation displacement contacts of the Dropwire terminal block after this incision. The press-in then takes place by means of the press-in webs which are adapted to the shape of the insulation displacement contact. When using the known insertion tool for Dropwire cable cores, two work steps are necessary to reduce the high insertion forces. In addition, the known insertion tool is technically complex and therefore expensive to manufacture.

Die vorangehend genannten Dropwire-Anschlußleisten sind aus dem DE-GM 8121 721 vorbekannt. Hierbei sind die Abstände der Klemmrippen auf die dicken Isolier­stoffhüllen der Dropwirekabel ausgelegt. Somit kön­nen die Klemmrippen dünne Kabeladern nicht sicher erfassen, welche mittels des Eindrückwerkzeuges in die Schneidklemmkontakte der Dropwire-An­schlußleiste eingedrückt werden. Es hat sich folglich gezeigt, daß sich die dünnen Kabeladern bei auf die Dropwire-Anschlußleisten einwir­kenden Schwingungen aus den Schneidklemmkontakten der Dropwire-Anschlußleisten herauslösen können, da die relativ dünne Isolierstoffhülle der dünnen Kabeladern von dem Klemmrippen der Dropwire-­Anschlußleiste nicht sicher erfaßt wird.The aforementioned Dropwire connection strips are previously known from DE-GM 8121 721. The distances between the clamping ribs are designed for the thick insulating sheaths of the drop wire cables. This means that the clamping ribs cannot reliably grasp thin cable cores that are pressed into the insulation displacement contacts of the Dropwire terminal block using the insertion tool. It has consequently been found that the thin cable cores can come loose from the insulation displacement contacts of the Dropwire connection strips when vibrations acting on the Dropwire connection strips, since the relatively thin insulating sleeve of the thin cable cores is not reliably gripped by the clamping ribs of the Dropwire connection strip.

Der Erfindung liegt somit die Aufgabe zugrunde, eine technisch einfache Vorrichtung der gat­tungsgemäßen Art zu schaffen, mit welcher dicke Dropwire-Kabeladern an den in den Dropwire-­Anschlußleisten angeordneten Schneidklemmkon­takten in einem Arbeitsschritt angeschlossen und dünne Kabeladern in Dropwire-Anschlußleisten sicher festgelegt werden können.The invention is therefore based on the object of providing a technically simple device of the generic type, with which thick Dropwire cable wires are connected to the insulation displacement contacts arranged in the Dropwire terminal strips in one work step and thin cable cores can be securely fixed in Dropwire connection strips.

Die Lösung dieser Aufgabe ergibt sich aus den kenn­zeichnenden Merkmalen des Anspruches 1. Das erfin­dungsgemäße Eindrückwerkzeug ist ein einfach und preiswert herstellbares Bauteil, insbesondere aus Kunststoff, das die Verbindung von Dropwire-Kabel­adern mit den Schneidklemmkontakten einer Dropwire-An­schlußleiste in einem einzigen Arbeitsschritt ermöglicht und ferner die Festlegung dünner Kabeladern in Dropwire-Anschlußleisten sicher­stellt. Bei Verwendung des Eindrückwerkzeuges zum Anschließen von Dropwire-Kabeladern an Dropwire-Anschlußleisten werden die hohen Ein­drückkräfte, welche durch die dicken Isolier­stoffhüllen der Dropwire-Kabeladern auftreten, durch einfach aufzubringende Schlag- oder Hebelkräfte überwunden, welche auf den An­griffskörper ausgeübt werden, der sich un­mittelbar an die Führungs- und Eindrückstege des Eindrückwerkzeuges anschließt.The solution to this problem results from the characterizing features of claim 1. The insertion tool according to the invention is a simple and inexpensive component, in particular made of plastic, which enables the connection of Dropwire cable cores to the insulation displacement contacts of a Dropwire terminal block in a single step and further ensures the definition of thin cable cores in Dropwire connection strips. When using the insertion tool for connecting Dropwire cable wires to Dropwire connection strips, the high insertion forces that occur due to the thick insulating sheaths of the Dropwire cable wires are overcome by easy-to-apply impact or lever forces that are exerted on the attacking body, which is immediately attached connects the guide and indentation bars of the indentation tool.

In besonders bevorzugter Weise besitzt das Eindrückwerkzeug auf der Oberseite seines Angriffskörpers eine Führungsnut zur Auflage des Hebelwerkzeuges, insbesondere eines Schrau­bendrehers. Die Spitze des Schraubendrehers greift unter eine Abstätzkante, die in einem geringen Abstand oberhalb der Schaltseite der Dropwire-Anschlußleiste und quer zur Führungsnut des Eindrückwerkzeuges verläuft. Durch eine Hebelbewegung des Schraubendrehers wird das Eindrückwerkzeug in die Anschlußleiste eingedrückt, wobei gleichzeitig in einem einzigen Arbeitsgang die Dropwire-Kabelader in den Schneidklemmkontakt eingebracht wird. Nach dem Eindrücken des Eindrück­werkzeuges in die Dropwire-Anschlußleiste befindet sich die Oberseite des Eindrückwerkzeuges unter der Ab­stützkante des Tragbleches. Trotz der geringen Bauhöhe des Eindrückwerkzeuges können die hohen Eindrückkräfte überwunden werden, die beim Beschalten von Dropwire-Anschlußleisten mit Dropwire-Kabel­adern mit der besonders dicken Isolierstoffhülle auftreten.In a particularly preferred manner, the insertion tool has a guide groove on the top of its engagement body for supporting the lever tool, in particular a screwdriver. The tip of the screwdriver engages under a scraping edge that runs a short distance above the switching side of the Dropwire terminal block and across the guide groove of the insertion tool. With a lever movement of the screwdriver Press-in tool pressed into the terminal block, the Dropwire cable core being inserted into the insulation displacement contact at the same time in a single operation. After pressing the insertion tool into the Dropwire connector strip, the top of the insertion tool is located under the support edge of the support plate. Despite the low overall height of the press-in tool, the high press-in forces that occur when wiring Dropwire connection strips with Dropwire cable cores with the particularly thick insulating material sleeve can be overcome.

Das Eindrückwerkzeug besteht insbesondere aus einem spritzttechnisch kostengünstig herstell­baren, schlagfesten Kunststoff. Damit kann an jeder Dropwire-Anschlußleiste ein Eindrückwerkzeug ständig vorhanden sein, indem dieses mittels einer Schnur oder dergleichen an der Dropwire-Anschlußleiste befestigt wird.The press-in tool consists in particular of an impact-resistant plastic which is inexpensive to produce by injection molding. This means that a press-in tool can always be present on each Dropwire connection strip by being attached to the Dropwire connection strip by means of a cord or the like.

Das erfindungsgemäße Eindrückwerkzeug kann auch als Schließstecker zum Halten dünner Kabel­adern in den Dropwire-Anschlußleisten dienen. Durch Verwendung des einen Schließstecker bil­denden Eindrückwerkzeuges aus Kunststoff ge­mäß dem Anspruch 5 können dünne Kabeladern in die Schniedklemmkontakte von Dropwire-Anschluß­leisten eingedrückt und andererseits in den Dropwire-Anschlußleisten sicher gehalten werden, da das Eindrückwerkzeug als Schließstecker in der Dropwire-Anschlußleiste verbleibt. Als Auf­nahme für die dünnen Kabeladern sind auf der Unterseite der Eindrückstege des Eindrückwerkzeuges Halterippen ausgebildet. In besonders bevorzugter Weise sind die Eindrückstege des Eindrückwerkzeuges je­doch aus zwei durch ein Filmscharnier verbundenen, verrastbaren Halbschalen gebildet, auf deren Innen­seiten je ein die Aufnahme für die dünne Kabelader bildender nutartiger Einlegekanal ausgebildet ist. Die dünne Kabelader wird in die auseinandergeklapp­ten Halbschalen eingelegt und beim Zusammenklap­pen der Halbschalen zwischen diesen fixiert. Nach dem Eindrücken des derart ausgebildeten Eindrück­werkzeuges in die Dropwire-Anschlußleiste ist die dünne Kabelader sicher fixiert.The insertion tool according to the invention can also serve as a locking plug for holding thin cable cores in the Dropwire connection strips. By using the plastic locking tool forming a locking plug according to claim 5, thin cable wires can be pressed into the insulation displacement contacts of Dropwire connection strips and, on the other hand, can be securely held in the Dropwire connection strips, since the insertion tool remains as a locking plug in the Dropwire connection strip. As a receptacle for the thin cable cores are on the Underside of the insertion webs of the insertion tool retaining ribs are formed. In a particularly preferred manner, however, the press-in webs of the press-in tool are formed from two latchable half-shells connected by a film hinge, on the inner sides of which a groove-like insertion channel forming the receptacle for the thin cable wire is formed. The thin cable core is inserted into the unfolded half shells and fixed between them when the half shells are folded together. After the insertion tool designed in this way has been pressed into the Dropwire connection strip, the thin cable core is securely fixed.

Ein besonders wesentlicher Vorteil des erfindungs­gemäßen, einen Schließstecker bildenden Eindrück­werkzeuges besteht darin, daß die dünne Kabelader vom Eindrückwerkzeug beim Einbringen in die Drop­wire-Anschlußleiste zentriert wird, so daß eine sichere Kontaktverbindung zwischen der dünnen Kabelader und em Schniedklemmkontakt der Drop­wire-Anschlußleiste sichergestellt ist. Beson­ders vorteilhaft ist auch, daß die dünne Kabel­ader beim Herausziehen des Schließsteckers mit herausgezogen werden kann.A particularly important advantage of the push-in tool according to the invention, which forms a locking plug, is that the thin cable core is centered by the push-in tool when it is introduced into the Dropwire terminal strip, so that a secure contact connection between the thin cable core and the insulation displacement contact of the Dropwire terminal strip is ensured. It is also particularly advantageous that the thin cable core can also be pulled out when the lock plug is pulled out.

Die Erfindung ist nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispie­les einer Vorrichtung zum Anschließen von Kabel­adern an Dropwire-Anschlußleisten und mehrerer im Zusammenhang mit dieser Vorrichtung verwendbaren Eindrückwerkzeugen näher erläutert.The invention is explained in more detail below on the basis of an exemplary embodiment of a device for connecting cable cores to Dropwire connection strips and a plurality of insertion tools that can be used in connection with this device.
