Description
Durchführung für elektrische Zeitungen. Bei elektrischen Apparaten, wie Konden satoren und Transformatoren, bei welchen eine Zuführung der Leiter durch ein metal lisches Gefäss zu erfolgen hat, muss eine Durchführung verwendet werden. Solche Durchführungen sind meistens derart kon struiert, dass ein in ein Isolationsmaterial wie Porzellan oder Bakelit eingebetteter Metall bolzen mittelst verschiedener Dichtungsflan schen fest gegen die Metallwand des Appa rates verschraubt wird. Soll der Apparat abgesichert- werden, was bei Kleinapparaten meistens der Fall ist, so muss zu diesem Zweck eigens ein viel Platz beanspruchendes Sicherungstableau erstellt werden.
Bei der Durchführung gemäss der Erfin dung werden diese Schwierigkeiten dadurch vermieden, dass die Durchführung mit einer Sicherung zusammengebaut ist. Die Durch führung kann beispielsweise mit einer in Bakelit eingepressten Scheibe versehen sein, mittelst der sie bequem in die Durchführungs stelle eingesetzt werden kann, so dass ein hermetischer Verschluss gewährleistet ist Ein mit einer derartigen Durchführung ver- sehener Apparat ist gegen allfällige Kurz schlüsse gesichert.
In der Zeichnung ist ein Ausführungs beispiel der Durchführung dargestellt.
In den Bakelitkörper 2 ist der Durch führungsbolzen 1 mit zentrischer Bohrung zur Aufnahme des Verbindungskabels, sowie eine metallische Scheibe 3 eingepresst. Der vorstehende Teil dieses Metallringes 3, der vom Bolzen 1 elektrisch isoliert ist, kann auf bequeme Weise in einen Metallbecher eingelötet oder mit demselben fest verschraubt werden. Das aus Porzellan oder anderem feuerfesten Isolationsmaterial bestehende . Sicherungsgehäuse 4 wird mittelst des Stell ringes 5 fest gegen den Bakelitkörper 2 ge presst. Zur Gewährleistung eines guten Kon taktes der Passschraube 7 der Sicherungs patrone 8 ist auf den Durchführungsbolzen 1 noch eine Mutter 6 geschraubt.
In üblicher Weise ist die Sicherungspatrone 8 durch den Stöpsel 10 in das Metallgewinde 9, welches mit Anschlussbolzen versehen ist, geschraubt. Das Isolationsstück 11 dient als Berührungs schutz des Anschlussbolzens.
An Stelle der gezeichneten Patronen. sicherung können auch andere Sicherungs systeme mit der Durchführung kombiniert werden.
Bushing for electric newspapers. A bushing must be used for electrical equipment such as condensers and transformers, where the conductors have to be fed through a metallic container. Such bushings are usually constructed in such a way that a metal bolt embedded in an insulation material such as porcelain or Bakelite is screwed firmly against the metal wall of the apparatus by means of various sealing flanges. If the device is to be secured, which is usually the case with small devices, a security panel that takes up a lot of space must be created for this purpose.
When performing according to the inven tion, these difficulties are avoided in that the implementation is assembled with a fuse. The lead-through can for example be provided with a disk pressed into Bakelite, by means of which it can be easily inserted into the lead-through point so that a hermetic seal is ensured. An apparatus provided with such a lead-through is secured against any short circuits.
In the drawing, an execution example of implementation is shown.
In the Bakelite body 2, the guide bolt 1 with a central bore for receiving the connecting cable, and a metallic disc 3 is pressed. The protruding part of this metal ring 3, which is electrically insulated from the bolt 1, can be conveniently soldered into a metal cup or screwed tightly to the same. That consisting of porcelain or other refractory insulation material. Fuse housing 4 is pressed firmly against the Bakelite body 2 by means of the adjusting ring 5. To ensure good contact with the fitting screw 7 of the fuse cartridge 8, a nut 6 is screwed onto the lead-through bolt 1.
In the usual way, the fuse cartridge 8 is screwed through the plug 10 into the metal thread 9, which is provided with connecting bolts. The insulation piece 11 serves as protection against contact of the connection bolt.
Instead of the cartridges drawn. securing, other securing systems can also be combined with the implementation.
