Gegenstand der Erfindung ist ein Hängeisolator derjenigen Art, bei der nach Zerstörung des Isolatorkörpers die Aufhängeteile kraftschlüssig gegeneinander liegen und so ein Herabfallen der aufgehängten Leitung unbedingt verhindern. Die Aufhängeteile sind hierbei in bekannter Weise aus einem Ring und einem Bolzen mit Kopf gebildet, dessen Durchmesser größer als der lichte Durchmesser des Ringes ist und der aus mehreren Teilen besteht. Der Isolatorkörper besitzt einen geschlossenen Kopf, und die Teile des Bolzenkopfes werden innerhalb des Isolatorkopfes in die für die Aufnahme von Zugkräften erforderliche Lage zueinander gebracht, wie es an sich auch bekannt ist.The invention relates to a suspension insulator of the type in which, after destruction of the insulator body, the suspension parts are non-positively against each other and so a It is essential to prevent the suspended cable from falling. The hanging parts are in As is known, formed from a ring and a bolt with a head, the diameter of which is larger than the inside diameter of the ring and which consists of several parts. The insulator body has a closed head, and the parts of the bolt head are inside the insulator head is brought into the position required to absorb tensile forces, as it is also known per se.

Die Erfindung besteht darin, daß entweder alle oder nur einzelne Teile des Bolzenkopfes getrennt vom Bolzenschaft in den Isolatorkopf eingeführt und dort mit dem Bolzen zu einem starren Körper verbunden werden, wobei der eine Teil aus einem zeitweise flüssigen oder plastischen Material bestehen kann. In der Zeichnung sind als Ausführungsbeispiele der Erfindung zwei Isolatoren dargestellt.The invention consists in that either all or only individual parts of the bolt head are separated inserted from the bolt shank into the insulator head and there with the bolt to one rigid body are connected, the one part consisting of a temporarily liquid or plastic material can exist. In the drawing are exemplary embodiments of the Invention shown two isolators.

In Fig. ι ist 1 der Isolierkörper, 2 der Tragring, an dem mittels Augen und Bolzen 3 der Bügel 4 mit der öse 5 befestigt ist. Der innen liegende Bolzenkopf ist aus sechs Stücken 6 zusammengesetzt, dessen unterer Teil zylindrisch ist und von dem Rohre 7 zusammengehalten wird (s. Schnitt A-B, Fig. 2). Innerhalb der Stücke 6 sitzt der Bolzen 8 mit dem Kopf 9, der den auf den Querbolzen 10 kommenden Zug auf die Teile 6 und durch deren obere kegelförmig auseinandergehende Enden und den Porzellankörper 1 auf den Ring 2 überträgt. Zwischen dem Porzellankörper 1 und dem Ring 2 sowie dem Bolzenkopf 9 sind Zwischenlagen 11, 12 von nachgiebigem Stoff (Blei ο. dgl.) eingefügt, um trotz geringer Unebenheiten eine gleichförmige Druckverteilung zu erzielen.In Fig. Ι 1 is the insulating body, 2 is the support ring to which the bracket 4 with the eyelet 5 is attached by means of eyes and bolts 3. The inner bolt head is composed of six pieces 6, the lower part of which is cylindrical and is held together by the tube 7 (see section AB, Fig. 2). Inside the pieces 6 is the bolt 8 with the head 9, which transmits the tension coming on the transverse bolt 10 to the parts 6 and through their upper conically diverging ends and the porcelain body 1 to the ring 2. Between the porcelain body 1 and the ring 2 and the bolt head 9, intermediate layers 11, 12 of flexible material (lead, etc.) are inserted in order to achieve a uniform pressure distribution despite slight unevenness.

Die Einbringung des Kopfes in den Isolierkörper geschieht in der Weise, daß zuerst der Bolzen 8 mit dem Kopf 9 so tief als möglich hineingesteckt wird, daß dann die Stücke 6 eingeführt, mit -ihren unteren Enden zu einem Zylinder um den Bolzenschaft 8 zusammengefügt, das Rohr 7 übergeschoben und nach Auflegen der Scheibe 13 durch Aufschrauben des Gabelstückes 14 die Kopfteile unverrückbar miteinander verbunden werden.The introduction of the head into the insulating body is done in such a way that the first Bolt 8 with the head 9 is inserted as deeply as possible that then the pieces 6 inserted, with their lower ends joined together to form a cylinder around the bolt shank 8, the tube 7 pushed over and after placing the disc 13 by screwing of the fork piece 14, the head parts are immovably connected to one another.

Ein Lösen der Schraube und damit der Kopfteile wird durch Einbringen des Stiftes 15 verhindert, der das Gewinde durchsetzt.Loosening of the screw and thus of the head parts is prevented by inserting the pin 15, which penetrates the thread.

Fig. 3 und 4 zeigen eine weitere Ausführungsform, bei der ein Isolierkörper 17 von grundsätzlich gleicher Bauart verwendet ist. Der Kopf, der in Fig. 4 im Grundriß dargestellt ist, besteht aus vier Teilen 18, die sich mit einer zylindrischen Innenfläche und der kegelförmigen unteren Fläche gegen die entsprechend geformte, mit Bund versehene Hülse 19 legen. Die Teile 18 haben ferner Ansätze 20, gegen die sich mit einer Kegelfläche die Mutter 21 legt. Letztere3 and 4 show a further embodiment in which an insulating body 17 of basically of the same design is used. The head, which is shown in plan in Fig. 4, consists of four parts 18, which deal with a cylindrical inner surface and the conical Place the lower surface against the appropriately shaped sleeve 19 provided with a collar. The parts 18 also have lugs 20 against which the nut 21 rests with a conical surface. Latter

Claims

is screwed onto the sleeve 19 with a left-hand thread and onto the bolt 22 with a right-hand thread. The assembling of the head? happens in this case in such a way that first the nut 21 after sliding the sleeve 19 is screwed onto the bolt 22 with two or three turns and inserted into the insulator opening. Then, with the sleeve 19 pushed back, all parts 18 are first inserted and then the sleeve 19 is pushed forward between the parts 18. By turning the bolt 22 relative to the sleeve 19, the nut 21 is screwed onto both the bolt 22 and the sleeve 19. Loosening of the parts of the head is prevented by the pin 23 penetrating through the sleeve and bolt. To hold the parts 18 together, cylindrical lugs and overlapping sleeves with cylindrical grooves can also be used instead of the conical surfaces. In order to prevent the bolt head from moving in the insulator head during shipping, it is advisable to pour a rubber or resin compound into the latter. The bolt head can also be made with the help of liquid or plastic material inside the insulator head. For this purpose, the end of the bolt to be inserted into the insulator head receives either a riveted or upset disc, or the bolt made of tube is flanged in the shape of a disc or expanded in a funnel shape by pressing or bending parts made by incisions. If cement is then to be used to manufacture the bolt head, the insulator head is expediently lined on the inside with a thin layer of paraffin and the bolts and cement paste are introduced into the hollow space that has been reduced in this way. After it has hardened, the paraffin is melted out. The finished bolt head then sits with play in the insulator head, and this prevents the latter from being blown up by driving the cement or when the temperature changes. If metal is to be used instead of cement, a paraffin lining of the insulator head cannot be used. However, the lining should also not be necessary, since the pouring with metal expediently requires the porcelain body to be heated prior to the pouring process. Now, however, the metal contracts more than the porcelain when it cools, and there is therefore readily a gap between the bolt head and the insulator head. If a larger clearance is desired, the insulator head could also be lined with molding sand, which can be removed after the casting has cooled down through the hollow bolt or pipes embedded in the cast body. White metal or another optionally softer and also more easily meltable alloy can be used to manufacture the head. Patent-A ν Proverbs:
