Description

Bei der Konstruktion der Verbundisolatoren hat die Herstellung einer brauchbaren Fassung der aus Papier oder Holz hergestellten Isolierstäbe bedeutende Schwierigkeiten bereitet. Der verwendete Werkstoff hat nicht genügende Festigkeit, um das Einschneiden von groben Gewindegängen zu ermöglichen. Die Gänge reißen vielmehr schon bei geringer Belastung ab.In the construction of the composite insulators, the manufacture of a useful one has to be considered Setting the insulating rods made of paper or wood significant difficulties prepares. The material used is not strong enough to cut into it to enable coarse threads. Rather, the gears tear at low levels Load off.

Um diesem Übelstand abzuhelfen, 'hat man bereits vorgeschlagen, konisch ausgedrehte Fassungen auf die Isolierstäbe aufzupressen, wobei sich die Notwendigkeit ergab, eine bestimmte Steigung der keilförmigen Fassungsfläche vorzusehen. Hierdurch wurde aber eine ganz bedeutende Verringerung des wirksamen Querschnittes bedingt.In order to remedy this problem, 'it has already been proposed to use a conical twist Pressing sockets onto the insulating rods, with the necessity of having a certain Provide slope of the wedge-shaped mounting surface. But this was causes a very significant reduction in the effective cross-section.

Gemäß der vorliegenden Erfindung wird dieser Mangel dadurch· behoben, daß an Stelle des einstufigen Konus ein mehrstufiger Konus gewählt wird, welcher auch bei Beibehaltung der durch Versuche festgestellten Steigung des Konus eine bedeutend bessere Ausnutzung des Stabquerschnitts ermöglicht. Der Gegenstand der Erfindung ist in der Zeichnung in einer beispielsweisen Ausführungsform dargestellt. According to the present invention, this deficiency is remedied by replacing of the single-stage cone, a multi-stage cone is selected, which is also retained if it is retained the incline of the cone determined by tests a significantly better utilization of the rod cross-section. The object of the invention is shown in the drawing in an exemplary embodiment shown.

Der aus Papier, Holz oder einem anderen Isolierstoff bestehende Stab 1 ist mit zwei konischen Fassungsflächen 2 und 3 versehen, in welche eine gemeinsame, den konischen Fassungsflächen entsprechend ausgebildete Schale 4 eingreift. Diese Schale besteht aus mehreren Teilen und besitzt außen die Form eines Doppelkonus. Nach Auflegen der Schalenteile auf den , IsoHerstab werden Ränge 5 und 6, welche innen eine den Außenkonussen der Schale entsprechende Steigung besitzen, auf die Schale aufgesetzt. Der untere Ring 6 besitzt außen ein Gewinde, durch welches er mit einem Flanschring 7 verbunden ist. Dieser Flanschring 7 und eine Druckscheibe 8 werden- mittels der Bolzenschraube 9 zusammengezogen und die beiden Druckringe 5 und 6 gegeneinandergedrückt, wodurch die Schalenteile 4 gegen den Isolierstab gepreßt werden. Sobald eine genügend große Pressung erzielt ist, werden die Ringe 5 und 6 auf den Schalenteil mittels Stifte o. dgl. befestigt. Der Flanschring 7 ist hierfür mit entsprechenden Durchbohrungen versehen. Nunmehr kann die Druckvorrichtung 7, 8, 9 abgenommen und an Stelle des Flanschringes 7 die zur Zugübertragung dienende Kappe aufThe rod 1 made of paper, wood or some other insulating material has two conical mounting surfaces 2 and 3 provided, in which a common, the conical Frame 4 engages accordingly formed shell. This shell is made of several parts and has the shape of a double cone on the outside. After hanging up the Shell parts on the, IsoHerstab are ranks 5 and 6, which inside are the outer cones have the same slope as the shell, placed on the shell. Of the The lower ring 6 has a thread on the outside by means of which it is connected to a flange ring 7 is. This flange ring 7 and a thrust washer 8 are - by means of the bolt screw 9 pulled together and the two pressure rings 5 and 6 pressed against each other, whereby the shell parts 4 against the insulating rod be pressed. As soon as a sufficiently high pressure is achieved, the rings 5 and 6 attached to the shell part by means of pins or the like. The flange ring 7 is for this with provide appropriate through-holes. The printing device 7, 8, 9 removed and in place of the flange ring 7 on the cap serving for the transmission of tension

das Gewinde des Druckringes 6 aufgeschraubt werden.the thread of the pressure ring 6 can be screwed on.
