Abstract

Bei einem Haltemagnetauslöser mit U-förmigem Joch­ körper (3) ist ein federbelasteter Klappanker (14) vorgesehen, der die Polschuhe des Jochkörpers (3) überbrückt und dessen Feder (18) an einer aus dem Anker (14) hochgeboge­ nen Zunge (17) angreift, wobei der Befestigungspunkt (19) der Feder (18) am Gehäuse (1) im Bereich einer die Stirnflächen der Enden (15, 16) der Schenkel (7, 8) des Jochkörpers (3) enthaltenden Ebene angeordnet ist. Weiters ist der Anker (14) im Winkelbereich zwischen dem Ende (16) des den Permanentmagnet (11) tragenden Schenkels (8) des Jochkörpers (3) und einem Lagerblech (22) gelagert, wobei das Lagerblech (22) über federnde Haltekrallen (23) am Schenkel (8) des Jochkörpers (3) befestigt ist und hochgebo­ gene Zungen (27) aufweist, die den Permanentmagnet (11) halten. With a holding magnet release with a U-shaped yoke body (3) a spring-loaded hinged anchor (14) is provided, which bridges the pole pieces of the yoke body (3) and the spring (18) of which is bent up from the armature (14) NEN tongue (17) attacks, the attachment point (19) the spring (18) on the housing (1) in the area of a End faces of the ends (15, 16) of the legs (7, 8) of the Yoke body (3) containing plane is arranged. Furthermore the anchor (14) is in the angular range between the end (16) of the leg (8) carrying the permanent magnet (11) of the Yoke body (3) and a bearing plate (22) mounted, wherein the bearing plate (22) on resilient retaining claws (23) on Leg (8) of the yoke body (3) is attached and raised has tongues (27) which hold the permanent magnet (11) hold.
