Description

Durch Patent 575 756 ist ein selbsttätiger Überstromschalter in Stöpselform unter Schutz gestellt, bei dem unmittelbar zwischen dem Schaltmechanismus und der Kontaktstelle eine parallel zur letzteren in dem Schaltergehäuse angeordnete Isolierwand vorgesehen ist, welche nur mit einer Durchtrittsöffnung für den entsprechend gestalteten und die Isolierwand übergreifenden beweglichen Kontaktarm versehen ist.By patent 575,756 is an automatic Overcurrent switch in plug form placed under protection, in which directly between the Switching mechanism and the contact point one parallel to the latter in the switch housing arranged insulating wall is provided, which only with a passage opening for the corresponding designed and the insulating wall overlapping movable contact arm provided is.

Die Erfindung bezieht sich auf eine weitere Ausbildung dieses Schalters. Sie besteht im wesentlichen in der Unterteilung des die Isolierwand umgreifenden Kontaktarmes in eine auf der Isolierwand liegende Kontakt-• brücke und einen mit dieser lose verbundenen Schalthebel. Diese Anordnung gestattet eine leichte Montage und ermöglicht die bequeme Auswechselung der Kontaktbrücke.The invention relates to a further embodiment of this switch. she consists essentially in the subdivision of the contact arm encompassing the insulating wall into a contact bridge located on the • insulating wall and one loosely connected to it Gear lever. This arrangement allows easy assembly and enables convenient Replacement of the contact bridge.

Auf der Zeichnung ist ein Anwendungsbeispiel der Erfindung in den Abb. 1 bis 3 dargestellt.In the drawing, an example of the application of the invention is shown in FIGS. 1 to 3 shown.

Quer durch das Schaltergehäuse a, b (Abb. ι und 2) geht die isolierende Trennwand 42. Unterhalb derselben befindet sich der Kniehebel k, I, m, der auf den aus dem federnden Schalthebel 43° und der Kontaktbrücke ib bestehenden Kontaktarm einwirkt. Für den Schalthebel 43« ist in der Isolierwand 42 eine Durchtrittsöffnung 420 vorgesehen.The insulating partition 42 goes transversely through the switch housing a, b (Fig. Ι and 2). Below this is the toggle lever k, I, m, which acts on the contact arm consisting of the resilient switching lever 43 ° and the contact bridge i b. A passage opening 42 0 is provided in the insulating wall 42 for the switching lever 43 ″.

Abb. ι zeigt den Schalter in der Einschaltstellung. Bei Überstrom wird der Tauchkern e von der Magnetspule 5 angezogen, so daß der Druck der Feder/ überwunden wird und der Stößer g den Kniehebel k, I zum Einknicken bringt. Dadurch wird der Schalthebel 43a freigegeben und die Kontaktbrücke ib von den festen Kontakten 4 entfernt. Diese Stellung zeigt Abb. 3. Beim Niederdrücken des Druckknopf es d geht die Vorrichtung in die Stellung Abb. 1 zurück. Der Druckknopf wird durch eine nicht gezeichnete Feder in die Ruhelage zurückgehoben.Fig. Ι shows the switch in the on position. In the event of an overcurrent, the plunger e is attracted by the magnetic coil 5, so that the pressure of the spring / is overcome and the pusher g causes the toggle lever k, I to buckle. As a result, the switching lever 43 a is released and the contact bridge i b is removed from the fixed contacts 4. This position is shown in Fig. 3. When the push button es d is depressed, the device returns to position Fig. 1. The push button is lifted back into the rest position by a spring (not shown).

Die Kontaktbrücke ib liegt lose zwischen der Isolierwand 42 und der Platte n. Sie ist isoliert von dem Hebel 43° durch die Hülse /, in welche der Hebel 43« greift.The contact bridge i b lies loosely between the insulating wall 42 and the plate n. It is isolated from the lever 43 ° by the sleeve / into which the lever 43 ″ engages.
