Der Anker (4) ist aus Einzelblechen (11, 16, 17) zusammengesetzt. Das dem Schenkel (10) benachbarte Blech (11) ist mit einer Abbiegung (12) ausgestattet, die zwischen Gehäusewand (13) und Schenkel (10) ragt. Hierdurch ist eine einfache Lagerung des Ankers im Gehäuse erreichbar, und zwar ohne Sonderbehandlung der Lagerstellen. Die Anordnung findet besonders Anwendung bei Kleinschützen.The invention relates to an air protection constructed from interlocking parts. The fixed magnetic part (2) together with the armature (4) and the actuating coil (3) pushed onto the leg are inserted transversely to the direction of movement of the armature (4) into a pot-shaped housing (1), one end of the armature (4) on one Leg (10) of the fixed magnetic part (2) abuts and the other end (19) can be connected to the contact carrier (20). The armature (4) is composed of individual sheets (11, 16, 17). The sheet (11) adjacent to the leg (10) is equipped with a bend (12) which projects between the housing wall (13) and leg (10). As a result, the armature can be easily stored in the housing, without special treatment of the bearing points. The arrangement is particularly useful for small shooters.

Description

Die Erfindung bezieht sich auf eine aus formschlüssig ineinandergreifenden Teilen aufgebautes Lüftschütz, dessen feststehendes Magnetteil samt Klappanker und auf einem Schenkel aufgeschobener Betätigungsspule in ein topfförmiges Gehäuse quer zur Bewegungsrichtung des Klappankers eingeschoben ist, wobei das eine Ende des Klappankers an einem Schenkel des feststehenden Magnetteils anliegt und das andere Ende mit dem Kontaktträger in Verbindung bringbar ist.The invention relates to a ventilator constructed from interlocking parts, the fixed magnetic part, including the hinged armature and the actuating coil pushed onto one leg, is inserted into a pot-shaped housing transversely to the direction of movement of the hinged armature, one end of the hinged armature abutting one leg of the stationary magnet part and the other end can be connected to the contact carrier.

Bei einem bekannten Luftschütz der obengenannten Art (DE-PS 11 33 010) ist der vom Anker betätigbare, die Kontaktstücke haltende Träger zwischen dem Boden des Gehäuses und dem Spulenkörper des Magneten verschiebbar geführt und mit dem Klappanker nach Art eines Kugel-oder Walzengelenkes formschlüssig verbunden. Diese Ver- bindung ist notwendig, um den Klappanker gegen Verschieben quer zur Bewegungsrichtung zu sichern. Die formschlüssige Verbindung kann jedoch zu einer Verkantung beim Verschieben des Kontaktträgers führen. Außerdem ist bei dieser bekannten Anordnung der feststehende Magnetteil über eine Schraube im Gehäuse gehalten.In a known air contactor of the type mentioned above (DE - PS 11 33 010), the armature, which supports the contact pieces and supports the carrier, is displaceably guided between the bottom of the housing and the coil body of the magnet and is positively connected to the hinged armature in the manner of a ball or roller joint . This Ver - bond is necessary to secure the hinged armature against displacement transversely to the direction of movement. However, the positive connection can lead to a tilt when moving the contact carrier. In addition, in this known arrangement the fixed magnetic part is held in the housing by means of a screw.

Durch die Erfindung soll ein Luftschütz der obengenannten Art geschaffen werden, das eine einfache Ankerführung unter Beibehaltung des fromschlüssigen Aufbaues ermöglicht. Die Aufgabe wird auf einfache Weise dadurch gelöst, daß der Anker aus Einzelblechen zusammengesetzt ist und das dem Anlageschenkel benachbarte Blech mit einer Abbiegung zwischen Gehäusewand und Schenkel ragt. Hierdurch ergibt sich eine relativ hohe mechanische Lebensdauer ohne eine Sonderbehandlung der Lagerstellen vornehmen zu müssen. Es sind keine Stanzkanten im Gleit-und Abrollbereich vorhanden und das Gerät kann mit gleichem Anker für Gleich- und Wechselstrombetrieb benutzt werden. Eine Vernietung oder sonstige Befestigung der Einzelbleche untereinander kann vermieden werden, wenn an den an die Abbiegung angrenzenden, um 90° versetzt liegenden Seitenkanten des Bleches vom Schenkel wegweisende, die weiteren Bleche zwischen sich aufnehmende Zungen abgebogen sind. Mit Vorteil können die Zungen auch zur Halterung von Andrückfedern dienen, sofern solche erforderlich sind. Ohne Schraubbefestigung für den feststehenden Magnetteil im Gehäuse kann ausgekommen werden, wenn der der Gehäusewand zugewandte Schenkel des feststehenden Magnetteiles über Ausgleichsrippen und Führungsanschläge in seiner Längsrichtung im Gehäuse gehalten ist. Gesonderte Befestigungsmittel für Polplatte oder Kurzschlußring können entfallen, wenn am anderen Schenkel eine Polplatte oder ein Kurzschlußring eingelegt ist und durch Anlage am Gehäuse gehalten ist.The invention is intended to provide an air contactor of the type mentioned above, which enables simple anchor guidance while maintaining the from the positive structure. The task is done in a simple way solved that the armature is composed of individual sheets and the sheet adjacent to the contact leg protrudes with a bend between the housing wall and leg. This results in a relatively long mechanical life without having to carry out special treatment of the bearing points. There are no punched edges in the sliding and unwinding area and the device can be used with the same anchor for direct and alternating current operation. A riveting or other fastening of the individual sheets to one another can be avoided if, at the side edges of the sheet adjacent to the bend, offset by 90 °, the tongues pointing away from the leg and the further sheets between them are bent. The tongues can also advantageously be used to hold pressure springs, if these are required. Without screw fastening for the fixed magnetic part in the housing, one can get by if the leg of the fixed magnetic part facing the housing wall is held in the longitudinal direction in the housing via compensating ribs and guide stops. Separate fasteners for the pole plate or short-circuit ring can be omitted if a pole plate or a short-circuit ring is inserted on the other leg and is held by contact with the housing.

  • 1 the contactor with magnet system and contact bridge carrier in side view in section in the off position,
  • 2 is a sectional view through the magnet system of FIG. 1 along the line II-II, in the on position,
  • 3 is a sectional view through the contactor of FIG. 1 along the line III-III,
  • Fig. 4 is a sectional view along the line IV-IV of Fig. 1, namely the bracket of the leg of the fixed magnetic part in the housing and
  • Figure 5 is a partial view of the contactor of Figure 1 in which a short-circuit ring for Wechselstrombe instead of the pole for DC operation -.. Is inserted powered.

In das Gehäuse 1 des Luftschützes ist der feststehende Magnetteil,2, auf den die Spule 3 mit dem Spulenkörper aufgeschoben ist, zusammen mit dem Anker 4, der aus einzelnen Blechplatten zusammengesetzt ist, eingeschoben. Am feststehenden Magnetteil 2 ist nach Fig. 1 eine Polplatte 5 eingelegt, die einerseits am Schenkel 6 des feststehenden Magnetteils 2 in entsprechende Nuten eingelegt ist und sich andererseits an Gehäusevorsprüngen 7 abstützt. Anstelle der Polplatte kann auch ein Kurzschlußring 8, wie aus Fig. 5 zu ersehen, eingelegt werden, der sich einerseits am Spulenkörper 9 der Spule 3 und andererseits am Schenkel 6 bzw. dem Gehäusevorsprung 7 abstützt. Das dem Schenkel 10 benachbarte Einzelblech 11 ist mit einer Abbiegung 12 ausgestattet, die zwischen Gehäusewand 13 und dem Schenkel 10 zu liegen kommt. Die durch die Abbiegung entstandene Rundung 14 bildet den Lagerpunkt für den gesamten Anker. Vom Schenkel 10 weggebogene Zungen 15 des Einzelbleches 11 dienen einerseits der Halterung der weiteren Einzelbleche 16 und 17 und andererseits zur Aufnahme der Andrückfedern 18, die den Anker auf den Schenkel 10 drücken. Das freie Ende 19 des Einzelbleches 17 dient als Verbindung von Anker 4 zu Kontaktträger 20, der durch die nicht näher dargestellten Rückdruckfedern für das Rückstellen des Ankers 4 sorgt. Dadurch, daß keine in allen Richtungen formschlüssige Verbindung zwischen Anker 4 und Kontaktträger 20 vorhanden ist, kann sich der Kontaktträger bei seiner Bewegung der entsprechenden Verschiebebahn leichter anpassen. Der Anker ist nach allen Seiten fixiert. Die Rundung 14 stützt sich am Gehäuse ab.In the housing 1 of the air contactor, the fixed magnetic part 2, onto which the coil 3 with the coil body is pushed, is inserted together with the armature 4, which is composed of individual sheet metal plates. 1, a pole plate 5 is inserted on the fixed magnetic part 2, which is inserted on the one hand on the leg 6 of the fixed magnetic part 2 in corresponding grooves and, on the other hand, is supported on housing projections 7. Instead of the pole plate, a short-circuit ring 8 can also be inserted, as can be seen in FIG. 5, which is supported on the one hand on the coil former 9 of the coil 3 and on the other hand on the leg 6 or the housing projection 7. The individual sheet 11 adjacent to the leg 10 is equipped with a bend 12 which comes to rest between the housing wall 13 and the leg 10. The curve 14 created by the bend forms the bearing point for the entire anchor. Tongues 15 of the individual sheet 11 bent away from the leg 10 serve on the one hand to hold the further individual sheets 16 and 17 and on the other hand to accommodate the pressure springs 18 which press the armature onto the leg 10. The free end 19 of the single sheet 17 serves as a connection from the armature 4 to the contact carrier 20, which provides for the resetting of the armature 4 by means of the return pressure springs (not shown). The fact that there is no positive connection between armature 4 and contact in all directions carrier 20 is present, the contact carrier can adapt more easily to its movement of the corresponding sliding track. The anchor is fixed on all sides. The curve 14 is supported on the housing.

Die Innenseite des Einzelbleches 11 liegt am Joch 10 an. Ein Verschieben in Längsrichtung des Ankers zum Kontaktträger 20 hin wird ebenfalls durch das Joch 10 durch die Abbiegung 12 verhindert. Entgegen der Bewegungsrichtung wird der Anker 4 durch die Gehäuserippe 21 oder die Druckfeder 18 gehalten. Die Querverschiebung wird durch weitere Gehäuserippen 22 ausgeschlossen. Eine paßgenaue Halterung der Spule erfolgt über Ausgleichsrippen 23 im Spulenkörper 9. Ein Verschieben des feststehenden Magnetteils 2 wird durch einen Gehäuseanschlag 24 einerseits und eine Ausgleichsrippe 25 andererseits verhindert. Außerdem erfolgt eine zusätzliche Halterung durch das Andrücken der Polplatte 5 bzw. des Kurzschlußringes 8 am Gehäusevorsprung 7.The inside of the single sheet 11 lies against the yoke 10. A displacement in the longitudinal direction of the armature towards the contact carrier 20 is also prevented by the yoke 10 through the bend 12. The armature 4 is held against the direction of movement by the housing rib 21 or the compression spring 18. The transverse displacement is excluded by further housing ribs 22. A precisely fitting holding of the coil takes place via compensating ribs 23 in the coil body 9. Moving the fixed magnetic part 2 is prevented by a housing stop 24 on the one hand and a compensating rib 25 on the other hand. In addition, there is an additional holder by pressing the pole plate 5 or the short-circuit ring 8 on the housing projection 7.

Zur Montage wird die Spule 3 mit dem Spulenkörper 9 auf den Schenkel des 6 des feststehenden Magnetteils aufgeschoben. Die Polplatte 5 bzw. der Kurzschlußring 8 eingelegt und hernach das komplette Bauteil, bestehend aus feststehendem Magnetteil 2, Spule 3, Polplatte bzw. Kurzschlußring und angelegtem Anker 4 gegebenenfalls mit Rückdruckfedern 18 in das Gehäuse 1 eingeschoben und über die oben geschilderten Anschläge fixiert. Es handelt sich hier somit um eine relativ einfache Montage.For assembly, the coil 3 with the coil body 9 is pushed onto the leg of the 6 of the fixed magnetic part. The pole plate 5 or the short-circuit ring 8 is inserted and then the complete component, consisting of the fixed magnetic part 2, coil 3, the pole plate or short-circuit ring and the armature 4, optionally inserted with back pressure springs 18 into the housing 1 and fixed via the stops described above. It is therefore a relatively simple assembly.

Es können im wesentlichen die gleichen Teile bis auf Kurzschlußring und Polplatte für Gleich- und Wechselstromausführung benutzt werden. Es sind keine zusätzlichen Befestigungsmittel für Kurzschlußring bzw. Polplatte wie Verstemmen, Versohrauben, Verschweißen notwendig. Die seitliche Führung des feststehenden Magnetteils 2 kann durch Gehäuseführungen, wie sie aus Fig. 4 zu ersehen sind, erfolgen.Essentially the same parts can be used except for the short-circuit ring and pole plate for DC and AC versions. No additional fasteners for the short-circuit ring or pole plate, such as caulking, screwing up, welding, are necessary. The lateral guidance of the fixed magnetic part 2 can be carried out by housing guides, as can be seen from FIG. 4.
