Abstract

Ein Magnetauslöser besteht aus einem Magnetanker (17) einem Magnetkern (14), einer zwischen beiden befindlichen, beide auseinanderdrückenden Feder (20), und einem Spulen­ körper (11). Zur Erleichtung der Montage ist der Spulenkörper (11) aus einem Blechteil aus nichtmagnetischem Material gebogen und besitzt an seinen beiden Stirnenden aufeinan­ der zuweisende Laschen (12, 13), deren Abstand kleiner ist als der Außendurchmesser von Magnetanker und Magnetkern. Die beiden Laschen (12 und 13) halten die im Inneren des Spulenkörpers befindlichen Teile fest, so daß der Spulenk­ örper zusammen mit den darin befindlichen Teilen eine Einheit bildet, deren Einzelteile unverlierbar sind. A magnetic release consists of a magnetic armature (17) a magnetic core (14), one between the two, both pushing apart spring (20), and a coil body (11). To make assembly easier, the bobbin is (11) from a sheet metal part made of non-magnetic material bent and has one another at its two ends the assigning tabs (12, 13), whose distance is less than the outside diameter of the magnet armature and magnet core. The two tabs (12 and 13) hold the inside of the Parts located on the bobbin so that the bobbin body together with the parts inside Unity forms, the individual parts are captive.
