Abstract

Bei einem Relais mit E-förmigem Joch (5) und einem querverschiebbaren Anker (12) greift je eine von zwei Polplatten (14, 15) des Ankers (12) in einen Freiraum zwischen Jochaußenschenkel(5′) und Jochkern (7) ein. In jeder Betriebslage schlägt eine der Polplatten (14, 15) am freien Ende (10) des Jochkerns (7) an. Durch die nach einem Schaltvorgang verbleibende Restmagnetisierung des Joches (5) kann die am Jochkern (7) anliegende Polplatte (14 oder 15) an diesem haften bleiben. Diese Haftkraft muß beim Umschalten durch eine entsprechend hohe Ansprechleistung überwunden werden. For a relay with an E-shaped yoke (5) and one cross-displaceable anchor (12) engages one of two Pole plates (14, 15) of the armature (12) in a free space between the yoke outer leg (5 ') and yoke core (7). In one of the pole plates (14, 15) at the free end (10) of the yoke core (7). By after a switching operation residual magnetization of the Yokes (5) can be the pole plate resting on the yoke core (7) (14 or 15) stick to it. This adhesive force must be switched by a correspondingly high Response power can be overcome.

Am Spulenflansch (11) sind am Jochkernende (10) anliegende Anschlagrippen (22) angeformt, die breiter als die Dicke des Jochkerns (7) sind und in einer solchen Länge über den Durchmesser des Jochkerns überstehen, daß beim Anschlagen der Polplatte (14, 15) ein Spalt (23) zwischen Polplatte (14, 15) und Jochkern (7) verbleibt. Diese Maßnahme verhindert das Haften des Ankers und bewirkt zugleich dessen Dämpfung beim Anschlagen der Polplatte (14, 15). At the coil flange (11) at the yoke core end (10) molded abutment ribs (22), the wider than the thickness of the yoke core (7) and in one such length over the diameter of the yoke core project that when the pole plate (14, 15) a gap (23) between the pole plate (14, 15) and the yoke core (7) remains. This measure prevents the Anchor and at the same time causes its damping when Striking the pole plate (14, 15).

Die Erfindung ist besonders geeignet für Miniatur-Flachrelais. The invention is particularly suitable for Miniature flat relay.
