Description

Die Erfindung besteht in einer weiteren Ausbildung von Schraubstöpselsicherungssockeln, bei denen die Kontaktorgane und die damit verbundenen Anschlußteile an einem kerämisehen Innenkörper angeordnet sind, während der Außenkörper des Sicherungssockels aus Isolierpreßstoff besteht.The invention consists in a further design of screw plug locking sockets, in which the contact organs and the connecting parts connected to them are seen on a kerämis Inner body are arranged, while the outer body of the fuse base is made of molded insulating material.

Nach der Erfindung besteht der die spannungführenden Teile des Elementensockels tragende keramische Körper aus einem keramischen Körper für das Fußkontaktstück mit seinen Anschlußorganen und aus einem solchen für die Kontaktgewindebrille mit ihren Anschlußorganen. Beide keramischen Körper sind in die Isolierpreßstoffumhüllung eingebettet und durch das Preßmaterial voneinander getrennt. Bei Anwendung der Erfin-"dung wird der Anteil des keramischen Baustoffes gegenüber Anordnungen nach dem Hauptpatent vermindert und ein sicherer Sitz des eingebetteten keramischen Baustoffes im Isolierpreßstoff gewährleistet.According to the invention, there is the live parts of the element base bearing ceramic body made of a ceramic body for the foot contact piece with its connecting organs and from such for the threaded contact glasses with their connecting organs. Both ceramic bodies are embedded in the molded insulating material and separated from each other by the molding material. When using the invention the proportion of ceramic building material is reduced compared to arrangements according to the main patent and a secure fit of the embedded ceramic building material in the insulating molded material.

Auf der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Bei der in Fig. i, 2 und 3 dargestellten Ausführung ist das Fußkontaktstück 1 mit dem daran sitzenden Anschluß- und Befestigungsbolzen 2 an einem verhältnismäßig kleinen keramischen Körper 3 befestigt. Die Kontaktgewindebrille 4 ist mit Hilfe ihres Anschlußbolzens 5 an einem zweiten keramischen Körper 6 angebracht. Die beiden Körper 3 und 6 mit den daran angebrachten Kontaktteilen sind mit Isolierpreßstoff 7 umpreßt. Die keramischen Körper haben zweckmäßig Vorsprünge 8 oder Kerben, um ihren Halt im Isolierpreßstoff zu verbessern.Exemplary embodiments of the invention are shown in the drawing. In the embodiment shown in Fig. I, 2 and 3, the foot contact piece 1 is with attached to the connecting and fastening bolt 2 sitting thereon on a relatively small ceramic body 3. the Contact thread glasses 4 is with the help of their connecting bolt 5 on a second ceramic Body 6 attached. The two bodies 3 and 6 with the contact parts attached to them are encapsulated with molded insulating material 7. The ceramic bodies expediently have projections 8 or notches in order to improve their hold in the molded insulating material.

Die Fig. 4 zeigt eine Anordnung, bei der lediglich das Fußkontaktstück 1 mit den daran sitzenden Anschlußbolzen 2 in derselben Weise, wie es Fig. 1 erkennen läßt, an einem keramischen Körper 3 befestigt ist. Die Kontaktgewindebrille 4 mit dem Anschlußbolzen 5 hingegen ist unmittelbar in den Isolierpreßstoff 7 eingelassen. ·Fig. 4 shows an arrangement in which only the foot contact piece 1 with it seated connecting bolt 2 in the same way as it can be seen in FIG. 1, on a ceramic Body 3 is attached. The contact thread glasses 4 with the connecting bolt 5, however is embedded directly in the molded insulating material 7. ·
