Abstract
Die Erfindung bezieht sich auf ein Schaltstück für elektri sche Schaltgeräte, insbesondere Schütze, mit etwa geradliniger Stromzuleitung und einem im Abstand zur Kontaktauflage geführ ten Lichtbogenleitblech, das in der Stromzuleitung U-förmig aus gebildet ist und dessen den Lichtbogen übernehmendes freies Ende etwa in der Ebene der Kontaktauflage verläuft. Der U-Schenkel ist im Bereich der Kontaktauflage von der Kontaktstelle weg parallel versetzt. Der andere Schenkel dient der Befestigung des Lichtbogenleitbleches. Hierzu ist in eine quaderförmige Stromzu leitung eine Nut eingebracht, in die ein Steg des Lichtbogen leitbleches zur Befestigung desselben einlegbar und befestigbar ist. The invention relates to a contact piece for electri cal switchgear, especially contactors, with approximately straight lines Power supply line and a distance from the contact pad th arc guide plate, the U-shaped in the power supply line is formed and its free end assuming the arc runs approximately in the level of the contact pad. The U-leg is in the area of the contact pad away from the contact point offset in parallel. The other leg is used to attach the Arc baffle. This is done in a cuboidal current line introduced a groove in which a web of the arc baffles can be inserted and fastened for fastening the same is.
