Description
Es ist bekannt, in einen den Isolierkörper achsial durchziehenden Kanal, einen Stab aus zugfestem Isolierstoff, beispielsweise aus getränktem Holz, einzulegen, um beim Bruch des Porzellankörpers das Herabfallen der Leitung zu verhüten. Der Stab ist an beiden Enden mit verdickten Köpfen versehen, die in einer Erweiterung des Kanals an den ebenfalls verdickten Enden des IsolierkörpersIt is known to use a rod in a channel axially traversing the insulating body tensile insulating material, for example made of impregnated wood, to be inserted in the event of a break the porcelain body to prevent the line from falling. The stick is on both Ends with thickened heads, which in an extension of the canal to the likewise thickened ends of the insulator
ίο kecken und gemeinsam mit diesem von der Befestigungskappe umschlossen werden, die am Porzellankörper angreift.ίο bold and shared with this from the Fastening cap are enclosed, which engages the porcelain body.
Bei dem Isolator, der den Gegenstand der Erfindung bildet, soll der eingelegte Stab__ iiicht nur das Herabfallen der Leitung bei iinem Bruch des Porzellankörpers verhüten, sondern auch den unversehrten Porzellankörper wenigstens teilweise von Zugbeanspruchungen entlasten. Erfindungsgemäß ist dem Stab eine gewisse Vorspannung gegen ien Isolierkörper gegeben. Der Stab sucht Jann den Isolierkörper in achsialer Richtung zusammenzudrücken. Dieser Druck wird aber lurch die Belastung des Isolators aufgehoben.In the case of the insulator, which forms the subject of the invention, the inserted rod __ iiDo not just prevent the cable from falling if the porcelain body breaks, but also the intact porcelain body at least partially from tensile stresses relieve. According to the invention, the rod is given a certain prestress against an insulating body. The staff is looking Then compress the insulator in the axial direction. This pressure will however lifted by the stress on the isolator.
Der durch die Belastung hervorgerufene Zug wird dadurch um die Vorspannung des Isolierstabes
vermindert.
In der Zeichnung sind Ausführungen der Erfindung beispielsweise dargestellt. In den
Kanal r des Porzellankörpers 2 mit den Schirmen 3, 4 ist der Stab 5 aus zugfestem Isolierstoff
eingelegt. Der Kanal 1 ist- an beiden Enden erweitert, in Abb. 1 trichterartig, in
Abb. 2 treppenartig. In dieser Erweiterung sitzt an dem einen Ende des Isolators der Einspannkopf
6 des Isolierstabes, am anderen Ende die Spannmuffe 7, die durch Gewinde
mit dem Stab 5 verbunden ist. Durch Anziehen der Spannmuffe 7 wird dem Stab 5
eine gewisse Vorspannung gegen den Porzellankörper erteilt. Der Isolator ist in an
sich, bekannter Weise mittels der verdickten Enden 8, 9 in den Kappen 10, 11 befestigt.The tension caused by the load is thereby reduced by the prestress of the insulating rod.
In the drawing, embodiments of the invention are shown by way of example. The rod 5 made of tensile insulating material is inserted into the channel r of the porcelain body 2 with the screens 3, 4. The channel 1 is widened at both ends, in Fig. 1 like a funnel, in Fig. 2 like a staircase. In this extension, the clamping head 6 of the insulating rod sits at one end of the insulator, and the clamping sleeve 7, which is connected to the rod 5 by a thread, is located at the other end. By tightening the clamping sleeve 7, the rod 5 is given a certain prestress against the porcelain body. The insulator is fastened in a manner known per se by means of the thickened ends 8, 9 in the caps 10, 11.
