Description
Die Erfindung bezieht sich auf ein Werkzeug zum Befestigen eines Schraubverbinders, in dessen rohrförmige Wandung mit einem Gewinde versehene Durchgangslöcher zur Aufnahme von Schrauben angebracht sind, an einem elektrischen Kabel. Das Werkzeug umfaßt ein Gehäuse und eine in diesem um ihre Achse drehbar angebrachte Welle, die an ihrem einem axialen Ende eine Aufnahme für den Kopf einer Schraube und an ihrem anderen axialen Ende eine Anlagefläche für ein zum Drehen der Welle geeignetes Antriebsmittel aufweist. Das Gehäuse weist zwei von diesem in Achsrichtung abstehende, von der Achse der Welle in radialer Richtung gleich weit entfernte Stifte auf, welche in Arbeitsposition an zwei einander gegenüberliegenden Seiten des Schraubverbinders anlegbar sind.The invention relates to a tool for fixing a screw connector, in the tubular wall of which threaded through holes for receiving screws are attached, to an electrical cable. The tool comprises a housing and a shaft rotatably mounted therein about its axis, which has at its one axial end a receptacle for the head of a screw and at its other axial end a bearing surface for a suitable shaft for rotating the drive means. The housing has two of this projecting in the axial direction, from the axis of the shaft in the radial direction equidistant pins, which are in working position on two opposite sides of the screw can be applied.
Der Begriff Schraubverbinder soll sowohl Schraubverbinder im eigentlichen Sinne als auch Schraubkabelschuhe umfassen. Ein Schraubverbinder ist ein rohrförmiger Verbinder aus Metall, in welchem zwei in den Verbinder eingeführte, zu verbindende Kabelenden mittels der in den Durchgangslöchern der Wandung angebrachten Schrauben festgestellt werden können. Ein Schraubkabelschuh ist für die Verbindung von einem Kabelende mit einem anderen elektrischen Bauteil vorgesehen und entsprechend aufgebaut.The term screw connector is intended to include both screw connectors in the true sense as well as Schraubkabelschuhe. A screw connector is a tubular connector made of metal, in which two cable ends inserted into the connector can be fixed by means of the screws mounted in the through-holes of the wall. A Schraubkabelschuh is provided for the connection of a cable end with another electrical component and constructed accordingly.
Um einen sicheren und langzeitstabilen elektrischen Kontakt und einen geringen Übergangswiderstand zwischen dem Leiter und dem Schraubverbinder zu erreichen, muß die Verbindung zwischen Kabel und Schraubverbinder mit ausreichend Kontaktkraft versehen werden. Die Schrauben des Schraubverbinders müssen deshalb mit einem vorbestimmten Drehmoment angezogen werden. Insbesondere bei relativ flexiblen Kabeln für den Nieder- und Mittelspannungsbereich kann es beim Festziehen der Schrauben durch einen Monteur durch die Übertragung des Drehmoments zum Verdrehen des Schraubverbinders und damit der Kabel kommen. Bei kleinen Schraubverbindern oder Schraubkabelschuhen ist es zudem wegen des relativ hohen Anzugsmoments dem Monteur nicht möglich, den Schraubverbinder während des Anziehens in der Hand zu halten.In order to achieve a secure and long-term stable electrical contact and a low contact resistance between the conductor and the screw connector, the connection between the cable and screw connector must be provided with sufficient contact force. The screws of the screw connector must therefore be tightened with a predetermined torque. Especially with relatively flexible cables for the low and medium voltage range, it can come when tightening the screws by a fitter by the transmission of torque for rotating the screw and thus the cable. In small Screw connectors or Schraubkabelschuhen it is also not possible because of the relatively high torque to the installer to hold the screw while tightening in the hand.
Werkzeuge zum Befestigen eines Schraubverbinders an einem Kabelende sind bekannt.Tools for attaching a screw connector to a cable end are known.
Beispielsweise kann der Schraubverbinder in einen mit einem Hebelarm ausgestatteten Gegenhalter eingeklemmt werden. Beim Anziehen der Schrauben durch den Monteur mittels eines Schraubenschlüssels kann dieser dank des Hebelarms der unerwünschten Drehbewegung besser gegenhalten.For example, the screw connector can be clamped in a equipped with a lever arm counter-holder. When tightening the screws by the fitter by means of a wrench this can better counteract the unwanted rotational movement thanks to the lever arm.
Nach einem anderen Beispiel kann ein Drehmomentverstärker zum Festziehen der Schrauben verwendet werden. Ein solches Werkzeug ist zum Beispiel in der
Ein solcher Drehmomentverstärker ist durch den festgelegten Abstand der Stifte zueinander für einen bestimmten Durchmesser des Schraubverbinders vorgesehen. Soll der Drehmomentverstärker für einen Schraubverbinder mit einem anderen Durchmesser verwendet werden, müssen die Stifte aus dem Verstärkergehäuse herausgeschraubt und an anderer, vorgesehener Stelle wieder eingeschraubt werden. Durch den festgelegten Stiftabstand kann es vorkommen, daß zumindest einer der Stifte das Kabel berührt. Dadurch kann es zu einer Beeinträchtigung des elektrischen Kontakts kommen, und die Isolierung des Kabels kann eingedrückt und beschädigt werden. Ebenso kann ein Stift eine andere, neben der gerade festzuziehenden Schraube liegende Schraube des Schraubverbinders berühren, wodurch der Drehmomentverstärker seiner Funktion nicht mehr richtig gerecht werden kann.Such a torque amplifier is provided by the fixed distance of the pins to each other for a given diameter of the screw. If the torque amplifier is to be used for a screw connector with a different diameter, the pins must be unscrewed from the amplifier housing and screwed in at another designated location. Due to the fixed pin spacing, it can happen that at least one of the pins touches the cable. This can lead to a deterioration of the electrical contact, and the insulation of the cable can be pressed and damaged. Likewise, a pin can be another, lying next to the currently tightening screw screw of Schraubverbinders touch, whereby the torque amplifier can no longer properly fulfill its function.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß das Werkzeug ein Verstellmittel aufweist, welches geeignet ist, die Stifte in symmetrischer Weise relativ zueinander und radial zu der Achse zu bewegen.This object is achieved according to the invention in that the tool has an adjusting means which is adapted to move the pins in a symmetrical manner relative to each other and radially to the axis.
Durch die mittels des Verstellmittels relativ zueinander und radial zu der Achse beweglichen Stifte erlaubt das erfindungsgemäße Werkzeug das Befestigen eines Schraubverbinders beliebigen Durchmessers an einem elektrischen Kabel. Dem Monteur ist es möglich, die Schrauben des Schraubverbinders ohne erheblichen Kraftaufwand anzuziehen. Eine einwandfreie elektrische Verbindung zwischen dem Kabel und dem Schraubverbinder kann so erreicht werden. Das erfindungsgemäße Werkzeug wird mit Vorteil zum Befestigen von Schraubverbindern im Nieder- und Mittelspannungsbereich eingesetzt. Dank des sicheren Greifens des Schraubverbinders und der komfortablen Handhabung des Werkzeugs während der Montage werden Verletzungen des Monteurs vorgebeugt und der Arbeitsschutz so verbessert. Andere Schrauben des Schraubverbinders oder das Kabel werden von dem Werkzeug nicht beeinflußt. Das erfindungsgemäße Werkzeug läßt sich flexibel und kontinuierlich an unterschiedliche Durchmesser von Schraubverbindern anpassen, ohne daß die Stifte neu montiert werden müssen, sodaß das Befestigen des Schraubverbinders an einem Kabel insgesamt zügiger durchgeführt werden kann. Für die Anpassung des Werkzeugs ist vorteilhafterweise keinerlei Sonderwerkzeug nötig.By means of the adjusting means relative to each other and radially to the axis movable pins allows the tool according to the invention the fastening of a screw of any diameter on an electric cable.

Thanks to the secure gripping of the screw connector and the comfortable handling of the tool during assembly, injuries to the fitter are prevented and the occupational safety is improved. Other screws of the screw connector or the cable are not affected by the tool. The tool according to the invention can be flexibly and continuously adapted to different diameters of screw connectors without the pins having to be remounted, so that the fastening of the screw connector to a cable can be carried out more rapidly as a whole. For the adaptation of the tool advantageously no special tool is necessary.
