Description
Es sind bereits zweiteilige Isolierschellen bekanntgeworden, die für Leitungen von verschiedenem Durchmesser verstellbar sind. Diese Schellen haben jedoch, .dan Nachteil, daß ihre Einstellbarkeit nur auf einen ver-. hältnismäßig Meinen Bereich beschrjänkt ist. Ein weiterer Übelstand .bestellt noch darin, daß auf Kriechwege keine/ Rücksicht genommen ist. Es ist zwar immer mehr die Forderung aufgestellt worden,, kabelähnliche Leitungen auf isolierenden Schellen zu verlegen, die beim Schadhaftwerden der Leitungsisolation einen Erdschluß verhindern, doch wird mit den bekannten Abstandschellen diese Forderung nicht erreicht. -Denn alle diese Schellen zeigen, daß der Kriechweg von 'dem unter Umständen spannungsführenden Mantel der kabelähnlichen Leitung zum Schellenbefestigungsmittel so klein ausfällt, daß im Hinblick auf die in feuchten und ammoniakhaltigen Räumen verwendeten Schellen von einer isolierenden Wirkung keine Rede sein kann. Es sind vielfach Fälle vorgekommen, bei denen trotz der auf Isolierschellen verlegten Leitungen Erdschluß festgestellt wurde, weil eben auf einen 'entsprechenden Kriechweg nicht geachtet worden ist.Two-part insulating clamps have already become known, which are used for cables of various types Are adjustable in diameter. However, these clamps have the disadvantage that their adjustability is limited to only one. My area is relatively limited. Another disadvantage is that there is no consideration for creeping paths is. It is true that the demand has been made more and more, cable-like Lay cables on insulating clamps to prevent damage to the cable insulation Prevent an earth fault, but with the known spacer clips this requirement has not been achieved. -Because all these clamps show that the creepage distance from the possibly live sheath of the cable-like line to clamp fasteners turns out so small that with regard to the in damp and rooms containing ammonia used clamps with an insulating effect can be out of the question. There have been many cases in which, despite the Isolation clamps laid cables ground fault was determined because just on a 'corresponding Creepage distance has not been respected.
Diese Übelstände werden nun durch die isolierende Schelle nach der Erfindung beseitigt, indem durch 'eine sinnreiche Bauart für möglichst lange Kriechwege gesorgt ist, ohne die Schelle in ihren bisher üblichen äußeren Abmessungen vergrößern zu müssen. Außerdem- wird ein besonders großer VersteUbarkeitsbereich für die verschiedenen Kabelquerschnitte geschaffen.These inconveniences are now eliminated by the insulating clamp according to the invention, by having an ingenious design the longest possible creepage distances are ensured without the clamp in its usual way to have to enlarge external dimensions. In addition, there is a particularly large area of controllability created for the different cable cross-sections.
In der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigen:The subject of the invention is shown in the drawing, namely show:

Die Schelle mit zwei oder mehreren EinsteUbereichen gemäß der Erfindung besteht aus 'einem Isolierstoff unterteil α und einem Isolierstoffoberteilb. Der Unterteil,« besitzt zwei oder mehrere Lagerstellen c, welche stufenartig angeordnet sind und 'eine unrunde Aussparung e, in welche ein Ansatz / des Oberteils b tief hineinragt, wodurch das Befestigungsmittel gegen die Leitungssieite hin abgedeckt ist. Dadurch wird ein größtmöglicher Kriechweg erreicht. Dier Schellenoberteil & wird je nach Bedarf mittels einer Rille &1 in ,eine der Lagerstellen c gesetzt. Durch diese verschiedenen 'Stufen, wovon jede ihren besonderen Einstellbereich hat, wird 'die Einstelhnöglichkeit vervielfacht, so daß ζ. B, mit einer Schelle mit zwiei Einstellbereichen mindestens zwei verschiedene Schellengrößen ersetzt werden. Eine Öffnung/:The clamp with two or more adjustment areas according to the invention consists of 'an insulating material lower part α and an insulating material upper part b. The lower part "has two or more bearing points c, which are arranged in a stepped manner, and" a non-circular recess e, into which a projection / of the upper part b protrudes deeply, whereby the fastening means is covered against the line wire. As a result, the greatest possible creepage distance is achieved. The upper part of the clamp & is placed in one of the bearing points c by means of a groove & 1 as required. Through these different 'levels, each of which has its own setting range,' the setting options are multiplied, so that ζ. B, a clamp with two adjustment ranges can be used to replace at least two different clamp sizes. An opening /:
