Das Befestigen der Spulen von Schaltgeräten, insbesondere von Schützen, erfolgt im allgemeinen unter Anwendung- der gebräuchlichen Befestigungsmittel, wie Splinte oder Schrauben. Insbesondere die weitverbreitete Verschraubung von der Rückseite des Gerätes her ist 'unvorteilhaft, weil diese Befestigungsmittel nach Einbau des gesamten Gerätes nur schwer zugänglich sind. Für die Wartung derartiger Geräte ist aber eine leichte, zeitsparendeThe fastening of the coils of switching devices, especially contactors, is generally carried out using the usual fasteners such as split pins or screws. In particular the widespread screw connection from the rear of the device is' disadvantageous because this Fastening means are difficult to access after the entire device has been installed. For maintenance such a device is a light, time-saving one ίο Austauschbarkeit der Schaltspulen erwünscht, und zwar ohne daß es dazu einer Abnahme des Schützes von der Wand oder seines Ausbaues aus einem Gerät bedarf. Auch soll möglichst das Lösen der Anschlüsse von den einzelnen Phasen unterbleiben. Andererseits dürfen die Spulenkörper und ihre Anschlußteile keine beim Transport leicht abbrechbaren Vorsprünge besitzen. Ferner wird verlangt, daß das Gerät auch nach den Kontaktunterbrechungsstellen zu lichtbogendicht abgeschlossen ist, um hohe Schaltleistungen zu erreichen. Infolgedessen darf der für eine leichte Auswechselbarkeit der Spulen erforderliche Raum den Lichtbogen keine Gelegenheit zu Überschlagen auf die Eisenteile des Magneten geben.ίο Interchangeability of the switching coils desired, and without the need to remove the contactor from the wall or remove it from one Device needs. Also, if possible, the connections should not be detached from the individual phases. On the other hand, the bobbins and their connecting parts must not break off easily during transport Have protrusions. It is also required that the device also after the contact break points too arc-tight to achieve high switching capacities. Consequently the space required for easy interchangeability of the coils may allow the arc no opportunity to roll over onto the iron parts of the magnet. Die an derartige Schaltgeräte bezüglich der Auswechselbarkeit ihrer Spulen gestellten Anforderungen werden unter Vermeidung der geschilderten Übelstände erfindungsgemäß in einfacher Weise durch eine solche Ausbildung der Funkenkammer erfüllt, daß die mit dem Sockel verbundene Funkenkammer zwischen den Schaltbrücken hindurchgreifende, die Magnetspule gegen den Sockel in ihre Betriebslage drückende Vorsprünge aufweist. Mit derartigen Vorsprängen an der Funkenkammer läßt sich erfindungsgemäß zugleich eine Abdichtung der Schalterkontakte gegeneinander erzielen, welche ein Überspringen von Lichtbogen auf die Eisenteile' verhindert. ■The requirements placed on such switching devices with regard to the interchangeability of their coils are according to the invention in a simple manner while avoiding the evils described fulfilled by such a design of the spark chamber that the spark chamber connected to the base between the jumpers reaching through, the solenoid against the base in their operating position has pressing projections. With such protrusions on the spark chamber According to the invention, the switch contacts can be sealed against one another at the same time Achieve, which prevents a jump of arcs on the iron parts'. ■ Die Zeichnungen zeigen die Ausbildung und An-Ordnung einer Funkenkammer nach der Erfindung, und zwar stelltThe drawings show the training and arrangement a spark chamber according to the invention, namely Fig. ι eine Ansicht des Gerätes im Schnitt und Fig. 2 eine Ansicht der Funkenkammer allein dar.Fig. Ι a view of the device in section and Fig. 2 is a view of the spark chamber alone. Wie aus Fig. 1 ersichtlich, setzt sich das Gehäuse des Schaltgerätes aus dem Sockel 1 und der aufgesetzten Funkenkammer 2 zusammen. Die beiden· Teile umschließen den Magnetkern 3, die Magnetspule 4 sowie die Isolierbrücke 5, welche die unter dem Druck von Federn 7 stehenden beweglichen Kontaktbrücken 6 enthält. Diese kommen bei Erregung der Magnetspule: 4 zur Anlage mit den festen Kontakten 8 im Isoliersockel. Die Funkenkammer 2 ist erfindungsgemäß mit Vorsprüngen 9 versehen, welche, auf die Magnetspule 4 druckend, diese in ihrer Betriebslage fixieren. Um eine sichere und erschütterungsfreie Lage der Magnetspule zu garantieren, ist diese auf einer elastischen Unterlage, nämlich einem gummielastischen Ring 10, gelagert.As can be seen from Fig. 1, the housing of the switching device consists of the base 1 and the attached spark chamber 2 together. The two parts enclose the magnetic core 3, the Magnet coil 4 and the insulating bridge 5, which are under the pressure of springs 7 movable Contains contact bridges 6. When the magnet coil is excited, these come with: 4 to the system the fixed contacts 8 in the insulating base. According to the invention, the spark chamber 2 is provided with projections 9 provided which, by printing on the solenoid 4, fix it in its operating position. Around To guarantee a safe and vibration-free position of the magnet coil, this is on a elastic base, namely a rubber elastic ring 10, stored. Wie insbesondere aus der Fig. 2, welche die Funkenkammer für sich allein darstellt, ersichtlich ist, sind die Vorsprünge 9 so ausgebildet, daß sie zugleich Trennwände 9' für die einzelnen Phasenkontakte innerhalb des Schaltgerätes bilden. Außerdem können sie auch die Führung für die Isolierbrücke 5 übernehmen.As can be seen in particular from FIG. 2, which shows the spark chamber on its own is, the projections 9 are formed so that they at the same time partition walls 9 'for the individual phase contacts form within the switching device. You can also use the guide for the insulating bridge 5 take over.
