Die bisherigen, zur Erdung von elektrischen Kabel- und Rohrleitungen verwendeten Klemmen, an denen der Erdleitungsdraht befestigt wird, haben sämtlich den Nachteil, daß zwischen dem KlemmoTgan und dem zu erdenden Rohr oder Kabel Zwischenräume bestehen bleiben, welche hinzutretender Feuchtigkeit, Luft oder Gasen Gelegenheit zur Oxydbildung geben. Die einmal einge-The previous ones used to ground electrical cables and pipes Clamps to which the ground wire is attached all have the disadvantage that between the KlemmoTgan and the pipe or cable to be earthed gaps remain, which additional moisture, air or gases opportunity give to oxide formation. The once
xo leitete Oxydbildung führt in kurzer Zeit zur Zerstörung der blanken Kontaktstellen, erhöht den Übergangswiderstand derselben und macht die Erdung völlig zwecklos.xo-directed oxide formation leads to the destruction of the bare contact points in a short time, increased the contact resistance of the same and makes the grounding completely pointless.
Die Erfindung macht es sich zur Aufgabe, eine Erdungsklemme zu schaffen, bei welcher die obengenannten Mängel der bisherigen Einrichtungen nicht auftreten können. Der Gegenstand der Erfindung besteht aus einer Lasche«, an welche ein mit Kontaktfett ge-The invention has for its object to provide a grounding terminal in which the above-mentioned deficiencies of the previous facilities cannot occur. The object of the invention consists of a tab «to which a contact grease
ao tränktes Metallgewebe b angenietet ist, sowie aus einem Bügel c mit den Schrauben d und e. Durch Anziehen der Schrauben d und e wird das weiche, getränkte Metallgewebe, alle Unebenheiten und Hohlräume in den Kontaktstellen zwischen Klemme und Rohr völlig ausfüllend, die Kontaktstellen gegen die schädlichen Einwirkungen von Feuchtigkeit, Luft und Gasen luftdicht abschließen.ao impregnated metal mesh b is riveted, as well as from a bracket c with the screws d and e. By tightening the screws d and e , the soft, soaked metal mesh completely fills all the bumps and voids in the contact points between the clamp and the pipe and seals the contact points airtight against the harmful effects of moisture, air and gases.
