Description

Elektrische Selbstschalter in Sockelform können im allgemeinen für höhere Kurzschlußabschaltströme gebaut werden als andere übliche Bauformen. Die Ursache hierfür liegt in der Möglichkeit, günstige Funkenkammern verbunden mit einer starken Funkenlöschung anordnen zu können. Die Herstellung dieser Schalter erfordert jedoch einen verhältnismäßig großen Aufwand an Material und Arbeitszeit.Electrical circuit breakers in socket form can generally be used for higher short-circuit breaking currents can be built than other common designs. the The reason for this lies in the possibility of cheap spark chambers connected with a to be able to arrange strong spark quenching. The manufacture of these switches requires however, a relatively large amount of material and labor.

Die Erfindung bedeutet demgegenüber eine erhebliche Vereinfachung und Verbilligung. Sie besteht im wesentlichen darin, daß die Funkenkammerwand gegenüber der Kontaktunterbrechungsstelle einen stutzenförmigen Ansatz besitzt, der die Spulenwicklung trägt. Dadurch werden die besonderen Spulenkörper gespart und der Aufbau und die Montage der Schalter sehr vereinfacht.In contrast, the invention means a considerable simplification and cheaper. It consists essentially in the fact that the spark chamber wall opposite the contact break point has a nozzle-shaped approach that the coil winding wearing. This saves the special bobbins and the structure and the Assembly of the switch is very simplified.

Die Zeichnung zeigt ein Anwendungsbeispiel der Erfindung.The drawing shows an application example of the invention.

Auf dem Sockel s steht der Magnetrahmen m, der die aus den Hälften c und d bestehende Funkenkammer und die Magnetspulen e und f umfaßt. Die Spulenhülsen g und h sind mit den Funkenkammerhälften aus einem Stück gepreßt. Sie bestehen aus funkensicherem Isolierstoff. Die Magnetspulen e und f werden entweder unmittelbar auf die Spulenhülsen gewickelt oder als Paketspule hergestellt und aufgeschoben. Zur Isolation der Spulenwicklung gegen den Magnetrahmen m dienen gestanzte Isolierscheiben i und k. In den Spulenhülsen g und h sitzen die Magnetkerne n. und o, in der Funkenkammer die Kontakte a und b. Der Kontakt b ist über die Stange L mit dem nicht gezeichneten Schaltmechanismus in Verbindung, auf welchen der bei p drehbar gelagerte und mit dem Tauchkern w versehene Auslöseanker v einwirkt.On the base s stands the magnetic frame m, which comprises the spark chamber consisting of halves c and d and the magnetic coils e and f. The bobbin tubes g and h are pressed from one piece with the spark chamber halves. They are made of spark-proof insulating material. The magnetic coils e and f are either wound directly onto the bobbin or manufactured as a package and pushed on. Punched insulating washers i and k are used to isolate the coil winding from the magnetic frame m. The magnetic cores n. And o sit in the coil sleeves g and h , the contacts a and b in the spark chamber. The contact b is connected via the rod L to the switching mechanism (not shown) on which the trip armature v, which is rotatably mounted at p and provided with the plunger w, acts.

Die Spulenhülsen können rund oder eckig sein. In jedem Fall ist für ihre Anfertigung praktisch kein Zeitaufwand erforderlich.The spool tubes can be round or square. In any case it is for practically no time is required to make them.
