Description

Metallteile, die im Inneren von keramischen Funkenkammern elektrischer Schalter angeordnet sind, z. B. Löschplatten oder -stifte, die quer zur Lichtbogenrichtung stehen, sind bisher durch Einkitten mittels feuerfester Kitte befestigt worden. Diese Befestigungsart ist in der Herstellung sehr zeitraubend und daher verhältnismäßig kostspielig. Auch kann der Kitt leicht abbröckeln und zwischen die Kontakte oder andere Schalterteile fallen und zu Störungen Anlaß geben.Metal parts that are inside of ceramic spark chambers electrical Switches are arranged, e.g. B. extinguishing plates or pins that are transverse to the direction of the arc have been fixed by cementing with fire-resistant putty. This type of attachment is very time consuming to manufacture and is therefore proportionate expensive. Also, the putty can easily crumble off and get between the contacts or other parts of the switch fall and give rise to malfunctions.

Erfindungsgemäß wird daher die Funkenkammer so ausgebildet, daß diese 'Metallteile an den Innenwänden der Funkenlzammer durch Einglasieren und darauffolgendes Brennen befestigt sind.According to the invention, therefore, the spark chamber is designed so that this '' Metal parts on the inner walls of the spark chamber by glazing and the following Burning are attached.

Ein Ausführungsbeispiel zeigt die Figur in Seitenansicht und Draufsicht auf eine Funkenkammer nach der Erfindung. Die vorzugsweise aus einem Stück bestehende keramische Funkenkammer a ist bereits beim Formen mit Nuten c zur Aufnahme der zu befestigenden Löschplatten b versehen. Letztere können an sich beliebige Form haben und mit Löchern, Ausschnitten od. dgl. versehen sein. Die Befestigung der Plattenerfolgt durch Bestreichen der Plattenkanten d mit Glasur und nachträgliches Brennen.The figure shows an exemplary embodiment in side view and top view on a spark chamber according to the invention. The one preferably consisting of one piece ceramic spark chamber a is already being formed with grooves c to accommodate the securing extinguishing plates b provided. The latter can have any shape per se and with holes, cutouts or the like. Be provided. The panels are attached by coating the plate edges d with glaze and then firing.

Diese Art der Befestigung ist nicht nur Sallherer und haltbarer, sondern bringt gegenü'3er dem Einkitten auch einen Arbeitszeitg: «-inn von etwa ; o °/o.This type of fastening is not only sallherer and more durable, but also brings a working time compared to puttying: "-inn of about; o ° / o.
