An electromagnetic tilting armature relay having one or more throw-over contacts, in which respect the central contact is held by spring force in the open position, and is moved by an armature-actuated tappet into the closed position, in which respect each central contact consists of the combination of a stationary contact lever with a contact lever mounted swingably thereon and in which respect a tension spring extending approximately in the direction of the contact plane is fastened on the one hand to the end of the contact carrier remote from the contacting and on the other hand to the movable contact lever in the vicinity of the double contact rivet, characterised in that the contact lever (2) is supported on both sides in knife-edge bearings (16 to 19) and the tension spring (5) draws the contact lever (2) into its knife-edge bearing (16, 17) and at the same time serves for the transfer of the actuating force, in which respect the actuation of the contact lever (2) is effected through the tappet (9) pressing directly on the tension spring (5), after the lifting-off of which tappet (9) the contact lever (2) snaps back.

Description

Die Erfindung betrifft ein elektromagnetisches Klappankerrelais mit einem oder mehreren Umschaltkontakten.The invention relates to an electromagnetic flap armature relay with one or more changeover contacts.

Der Kontaktabstand derartiger herkömmlicher Relais mit Umschaltkontakten ist nur auf wenige Zehntelmillimeter begrenzt, weil der maximale Ankerhub eines Klappanker- . relais vorgegebener Größe festliegt.The contact distance of such conventional relays with changeover contacts is only limited to a few tenths of a millimeter because the maximum armature stroke of a hinged armature. relay of a specified size.

Der Erfindung liegt die Aufgabe zugrunde, den Kontakthub eines Klappankerrelais über das Zehnfache hinaus zu vergrößern, weil in der Schalttechnik neuerdings aus Sicherheitsgründen in den Fällen, in denen Ströme mit höherer Spannung zu schalten sind, ein größerer Kontaktabstand erforderlich ist.The invention has for its object to increase the contact stroke of a hinged armature relay more than ten times because in switching technology, for safety reasons, a greater contact spacing is now required in cases in which currents with a higher voltage are to be switched.

Der Erfindung liegt weiterhin die Aufgabe zugrunde, den Klappanker möglichst prellarm schalten zu lassen, um dadurch die Lebensdauer der bewegten Teile des Relais zu erhöhen.The invention is also based on the object of having the hinged armature switch with as little bounce as possible, in order thereby to increase the service life of the moving parts of the relay.

Erfindungsgemäß wird die erstgenannte Aufgabe dadurch gelöst, daß jeder Mittelkontakt aus der Kombination eines ortsfesten Kontaktträgers mit einem schwenkbar gelagerten Kontakthebel besteht, wobei eine ungefähr in Richtung der Kontaktebene sich erstreckende Zugfeder einerseits an dem der Kontaktierung abgewendeten Ende des Kontaktträgers und andererseits in der Nähe des Doppelkontaktnietes an dem Kontakthebel befestigt ist, hierbei die zweiseitige Lagerung des Kontakthebels in bezug auf die jeweils mögliche Zugfederwirkung auf den Kontaktträger so angelegt ist, daß der Mittelkontakt wahlweise ein Rückstell- oder ein Schnappverhalten zeigt, während zur Beeinflussung der Stellung des Umschaltkontaktes die Einwirkung eines ankerbetätigten, unmittelbar auf die Zugfeder oder den Kontakthebel drückenden oder ziehenden Stößels erfolgt.According to the invention, the first-mentioned object is achieved in that each center contact consists of the combination of a fixed contact carrier with a pivotably mounted contact lever, an extension spring extending approximately in the direction of the contact plane on the one hand at the end of the contact carrier facing away from the contact and on the other hand in the vicinity of the double contact rivet is attached to the contact lever, the two-sided mounting of the contact lever with respect to the possible tension spring effect on the contact carrier is applied so that the means Contact shows either a reset or a snap behavior, while to influence the position of the changeover contact, the action of an anchor-operated, directly on the tension spring or the contact lever pushing or pulling plunger takes place.

Das erfindungsgemäß ausgestattete Klappankerrelais bietet die Möglichkeit, durch zweckmäßige Wahl der Hebelverhältnisse einen vergrößerten Kontaktabstand zu erzielen, obwohl die Kontaktkraft nicht verringert wird. Da sich die den Kontakthebel in die Ruhelage zurückholende Zugfeder ungefähr in Richtung der Kontaktebene erstreckt, ist deren Platzbedarf vernachlässigbar gering und führt zu keiner Vergrößerung der baulichen Abmessungen des Klappankerrelais, verglichen mit einem herkömmlichen. Es ist lediglich der Abstand der feststehenden Kontakte, entsprechend den elektrischen Gegebenheiten, zu vergrößern.The folding armature relay equipped according to the invention offers the possibility of achieving an increased contact distance by appropriately selecting the lever ratios, although the contact force is not reduced. Since the tension spring returning the contact lever to the rest position extends approximately in the direction of the contact plane, its space requirement is negligibly small and does not lead to an increase in the structural dimensions of the folding armature relay compared to a conventional one. It is only necessary to increase the distance between the fixed contacts in accordance with the electrical conditions.

In Weiterbildung der Erfindung ist der den Doppelkontaktniet tragende Kontakthebel auf beiden Seiten in Schneidenlagerungen abgestützt und weist eine mittlere Aussparung auf, beiderseits derer sich seitliche Vorsprünge mit Kanten erstrecken. Es wird so eine besonders kompakte Bauweise erzielt, wobei die Abkröpfung der Kontaktträgerabschnitte dennoch die erforderliche Exzentrizität der Zugfeder gegenüber der Schneidenlagerung des Hebels herbeizuführen gestattet.In a further development of the invention, the contact lever carrying the double contact rivet is supported on both sides in cutting edge bearings and has a central recess, on both sides of which lateral projections extend with edges. A particularly compact design is achieved in this way, the offset of the contact carrier sections nevertheless allowing the required eccentricity of the tension spring to be brought about in relation to the cutting edge bearing of the lever.

Um einen möglichst großen Schwenkweg des Doppelkontaktnietes, der am Ende des ihn tragenden Kontakthebels sitzt, bei festliegendem Ankerhub erzeugen zu können, drückt der Stößel auf den dem Lager des Hebels abgewandten, außerhalb des Hebels liegenden Teil der Zugfeder.In order to be able to produce the largest possible swivel path of the double contact rivet, which sits at the end of the contact lever carrying it, with the anchor stroke fixed, the plunger presses on the part of the tension spring facing away from the bearing of the lever and lying outside the lever.

Das erfindungsgemäß ausgestattete Klappankerrelais erlaubt es mithin, durch zweckmäßige Wahl der Hebelverhältnisse, also sowohl der Länge des den Doppelkontaktniet tragenden Kontakthebels, des Abstandes zwischen dem Lager dieses Kontakthebels und der Richtung der Zugkraft der Zugfeder und des Angriffspunktes derselben an dem Kontakthebel als auch der Lage des Angriffspunktes des Stößels an der Zugfeder selbst, ein den jeweils vorliegenden Schaltbedingungen angepaßtes Schaltverhalten des Relais zu erzielen. Der Doppelkontaktniet liegt.dabei in der Ruhestellung stets in der einen Endlage eines Schnappschalters, während er durch den ankerbetätigten Stößel aus dieser Schnappendlage herausgedrückt, beispielsweise jedoch über die Mittellage, aus der er in die andere Endlage schnappen könnte, nicht hinausbewegt wird, so daß er bei abfallendem Klappanker stets wieder in die Ruhestellung zurückschnappt.The hinged armature relay equipped according to the invention therefore allows, by appropriate selection of the lever ratios, i.e. both the length of the contact lever carrying the double contact rivet, the distance between the bearing of this contact lever and the direction of the tensile force of the tension spring and the point of application thereof on the contact lever as well as the position of the Point of contact of the plunger on the tension spring itself to achieve a switching behavior of the relay that is adapted to the respective switching conditions. In the rest position, the double contact rivet is always in the one end position of a snap switch, while it is pushed out of this snap end position by the anchor-operated plunger, but is not moved beyond the middle position, for example, from which it could snap into the other end position, so that it always snaps back into the rest position when the hinged anchor falls off.

Das angestrebte prellarme Verhalten des Ankers des erfindungsgemäßen Klappankerrelais wird dadurch bewirkt, daß der an dem Befestigungsschenkel des Joches anliegend Flansch der Erregerspule aus einem energieverzehrenden Material, beispielsweise einem geeigneten Kunststoff, besteht, und einen eine Durchbrechung des Joches berührungsfrei durchgreifenden, der Dämpfung der Prellungen des abfallenden Ankers dienenden, einen Anschlag für den das Joch übergreifenden Ankerschenkel bildenden Ansatz besitzt. Dadurch, daß der an dem Befestigungsschenkel des Joches anliegende Flansch der Erregerspule aus energieverzehrendem Material, beispielsweise einem thermoplastischen Kunststoff, besteht, bildet der an dem Flansch angeordnete, eine Durchbrechung des Joches durchgreifende Ansatz einen Anschlag für den in Längsrichtung der Erregerspule sich erstreckenden Ankerschenkel, der bei Entregung des Relais die durch die Spannung der Kontaktfedern bedingte Bewegungsenergie des Ankers beim Aufprall aufzehrt und gleichzeitig einen bei Berührung des Ankerschenkels mit dem Joch sich ergebenden magnetischen Nebenschluß verhinderto Zusätzliche Aufwendungen sind weder bei der Herstellung noch bei der Montage erforderlich, da die Durchbrechung des Joches gleichzeitig mit dem sowieso erforderlichen Stanzen erfolgt, und der Ansatz ohne Schwierigkeiten bei der Herstellung des Flansches angeformt wird. Auch die Montage erfordert keinerlei zusätzliche Maßnahmen, und es besteht darüberhinaus die Möglichkeit, den Ansatz in Anpassung an einen erforderlichen Ankerhub auf einfache Weise durch Abtragung zu verkürzen, was bei Verwendung eines thermoplastischen Materials, beispielsweise durch Wärmeeinwirkung, erfolgen kann.The desired low-bounce behavior of the armature of the hinged armature relay according to the invention is brought about by the fact that the flange of the excitation coil lying on the fastening leg of the yoke consists of an energy-consuming material, for example a suitable plastic, and a break through of the yoke without contact, the damping of the bruises sloping anchor serving, a stop for the approach across the yoke anchor leg approach. The fact that the on the fastening supply leg of the yoke adjacent flange of the excitation coil made of energy-consuming material, for example a thermoplastic, the flange arranged on the flange, penetrating through the yoke approach forms a stop for the armature leg extending in the longitudinal direction of the excitation coil, which by de-energizing the relay the tension of the contact springs consumes the kinetic energy of the armature upon impact and, at the same time, prevents a magnetic shunt resulting from contact of the armature leg with the yoke takes place, and the approach is molded on without difficulty in the manufacture of the flange. The assembly also does not require any additional measures, and there is also the possibility of shortening the approach in adaptation to a required anchor stroke in a simple manner by removal, which can be done when using a thermoplastic material, for example by exposure to heat.

Ein weiteres Merkmal des erfindungsgemäßen Relais besteht darin, daß der am freien Ende der Erregerspule angeordnete Flansch aus einem energieverzehrenden Material beispielsweise Kunststoff, besteht und wenigstens einen, der Dämpfung der Prellung des anziehenden Ankers dienenden, gegenüber dem Spulenkern geringfügig vorspringenden, einen Anschlag für den quer zum Spulenkern gerichteten Ankerschenkel bildenden Vorsprung aufweisto Wenn auch die bei Erregung des Relais sich ergebenden Ankerprellungen in befriedigendem Maße gedämpft werden sollen, ist lediglich erforderlich, an dem am freien Ende der Erregerspule angeordneten Flansch einen parallel zur Spulenachse gerichteten Vorsprung anzuformen, der in seiner Länge den vorstehenden Spulenkern um ein geringes Maß überschreitet, und an dem bei Erregung des-Relais der quer zur Erregerspule gerichtete Ankerschenkel zur Anlage kommt, wobei ebenfalls eine befriedigende Dämpfung der Ankerprellungen erreicht wird.Another feature of the relay according to the invention is that the flange arranged at the free end of the excitation coil consists of an energy-consuming material, for example plastic, and at least one stop, which serves to dampen the bruise of the attracting armature and protrudes slightly towards the coil core, for the transverse has protrusion forming the armature arm directed towards the coil core o Even if the resulting when the relay is excited Anchor bruises are to be dampened to a satisfactory extent, it is only necessary to form a projection parallel to the coil axis on the flange arranged at the free end of the excitation coil, which protrudes in length by a small amount, and on the excitation of the relay the armature arm, which is directed transversely to the excitation coil, comes into contact, whereby a satisfactory damping of the armature bruises is also achieved.

Zweckmäßigerweise wird unmittelbar unterhalb des Spulenkerns der Vorsprung angeordnet; es können jedoch auch mehrere Vorsprünge angeordnet sein, die den unteren Bereich des Spulenkerns auf einem Kreisbogen umgebeno Auch die Anordnung des Vorsprungs macht keinerlei zusätzliche Aufwendungen in der Herstellung und in der Montage erforderlich, da er bei der Herstellung des Flansches ohne Schwierigkeiten angeformt werden kann.The projection is expediently arranged directly below the coil core; However, several projections can also be arranged, which surround the lower region of the coil core on an arc of a circle. The arrangement of the projection does not require any additional expenditure in terms of manufacture and assembly, since it can be molded on without difficulty during the manufacture of the flange.

Weitere Merkmale der Erfindung sind in den Unteransprüchen angegeben.Further features of the invention are specified in the subclaims.

The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawing. Show it:
  • FIG o 1 is a side view of a hinged-armature relay, for example, carried out,
  • O 2 of the same, the front view of Fig,
  • 3 shows the changeover contact group in a basic representation for the rest position of the electromagnetic drive,

Gem. Fig.l ist der den Doppelkontaktniet 1 tragende Kontakthebel 2 in der Kantenlagerung 3 an dem Kontaktträger 4 abgestützt. Die Zugfeder 5 ist mit ihrem einen Ende 6 an dem Kontaktträger 4 und mit ihrem anderen Ende 7 an dem Kontakthebel 2, in diesem Falle durch einfaches Einhaken, befestigt. Wie aus der Zeichnung ersichtlich, liegt die Längsachse 5a der Zugfeder 5 in der Mittellage des beweglichen Doppelkontaktnietes 1 neben der Kantenlagerung 3, so daß immer noch eine erhebliche Rückholkomponente auf den Kontakthebel 2 ausgeübt wirdo Diese bleibt auch dann erhalten, wenn der Doppelkontaktniet 1 bis zur Anlage an den feststehenden Kontakt 8 geschwenkt worden ist (s.hierzu auch Fig.4).According to FIG. 1, the contact lever 2 carrying the double contact rivet 1 is supported in the edge bearing 3 on the contact carrier 4. The tension spring 5 is fixed at one end 6 to the contact carrier 4 and at the other end 7 to the contact lever 2, in this case by simply hooking it on. As can be seen from the drawing, the longitudinal axis 5a of the tension spring 5 lies in the central position of the movable double contact rivet 1 next to the edge bearing 3, so that a considerable return component is still exerted on the contact lever 2 System has been pivoted to the fixed contact 8 (see also Fig. 4).

Diese Schwenkung wird durch den ankerbetätigten Stößel 9 bewirkt, der unmittelbar auf die Zugfeder 5 drückt Der durch den festliegenden Ankerhub begrenzte Schalthub des Stößels 9 wird durch das vorliegende Hebelverhältnis um ein Mehrfaches übersetzt, wodurch dergewünschte große Schalthub und damit Abstand zwischen dem Doppelkontaktniet 1 in seinen Endstellungen und dem jeweils gegenüberliegenden feststehenden Kontakt 8 bzw. 10 gewährleistet ist. Fig.3 zeigt die zweite Endstellung des Doppelkontaktnietes 1, in der dieser durch die Zugfeder 5 in die Ruhelage 0zurückgeholt worden istoThis pivoting is brought about by the armature-actuated plunger 9, which presses directly on the tension spring 5. The switching stroke of the plunger 9 limited by the fixed armature stroke is achieved by the present lever ratio translated by a multiple, whereby the desired large switching stroke and thus the distance between the double contact rivet 1 in its end positions and the opposite fixed contact 8 or 10 is ensured. 3 shows the second end position of the double contact rivet 1, in which it has been brought back into the rest position 0 by the tension spring 5

Der Kontakthebel 2 enthält, wie Fig. 2 erkennen läßt, eine mittlere Aussparung 11, durch die die Zugfeder 5 hindurchgreift. Die beiderseitigen Vorsprünge (14,15) der Kontaktträgerabschnitte 12 und 13 sind,wie Fig. 1 erkennen läßt, abgewinkelt und die beiderseitigen Streben 4a und 4b versetzt gebogen, um das Hebelverhältnis zu verbessern. Die Kanten 16 und 17 der seitlichen, abgewinkelten Vorsprünge 14 und 15 greifen in die Ausnehmungen 18 und 19 der Vorsprünge 12 und 13 des Trägers 4, wodurch eine reibungsarme Lagerung des Kontakthebels 2 gewährleistet ist.As can be seen in FIG. 2, the contact lever 2 contains a central recess 11 through which the tension spring 5 extends. The projections (14, 15) on both sides of the contact carrier sections 12 and 13 are angled, as can be seen in FIG. 1, and the struts 4a and 4b on both sides are bent offset to improve the leverage ratio. The edges 16 and 17 of the lateral, angled projections 14 and 15 engage in the recesses 18 and 19 of the projections 12 and 13 of the carrier 4, which ensures low-friction mounting of the contact lever 2.

Die Fig. 5 u.6 zeigen lediglich die Erregerspule 21 mit dem Spulenkern 22 und dem Joch 23, 23' und dem Klappanker 24; 25. Der Kontaktfedersatz und das diesen betätigende, auf der Oberseite des Ankerschenkels 24 aufliegende Organ sind fortgelassen, da sie zur Erläuterung der Erfindung nicht erforderlieh sind.5 and 6 only show the excitation coil 21 with the coil core 22 and the yoke 23, 23 'and the hinged armature 24; 25. The contact spring set and the actuating element, which rests on the upper side of the armature leg 24, are omitted, since they are not required to explain the invention.

Wie die Abbildungen zeigen, besitzt das Joch 23, 23' an der Stelle der Abbiegung eine im Stanzwege bei der Herstellung des Joches eingeprachte Durchbrechung 28, und der an dem Befestigungsschenkel 23 'des Joches anliegende Flansch der Erregerspule 21 besitzt einen, die Durchbrechung 28 frei durchgreifenden stiftförmigen Ansatz 29 der oberhalb des Jochschenkels 23 endet und einen Anschlag für den Ankerschenkel 24 bildet, wenn das Relais entregt und der Anker 24, 25 unter Wirkung der Spannung der Kontaktfedern in die in Fig.6 gezeigte Lage gebracht wird.As the figures show, the yoke 23, 23 'at the point of the bend has an opening 28 which is impressed in the punching path during the manufacture of the yoke, and the flange of the excitation coil 21 which bears against the fastening leg 23' of the yoke has one, the through Refraction 28 freely penetrating pin-shaped projection 29 which ends above the yoke leg 23 and forms a stop for the armature leg 24 when the relay de-energizes and the armature 24, 25 is brought into the position shown in FIG. 6 under the action of the tension of the contact springs.

Wie Fig.6 zeigt, ist zur Dämpfung der bei Erregung des Relais auftretenden Ankerprellungen an dem am freien Ende der Erregerspule 21 angeordneten Flansch 27 ein parallel zur Achse der Erregerspule 21 gerichteter Ansatz 30 angeordnet, der geringfügig gegenüber dem Spulenkern 22 vorsteht, so daß bei Erregung des Relais der Ankerschenke1 25 in Anlage an den Ansatz 30 gelangt und die Ankerprellungen dämpft. Der Ansatz 30 läßt sich ohne Schwierigkeiten bei der Herstellung des Flansches 27 in ein und demselben Arbeitsgang anformen.As shown in FIG. 6, for the damping of the armature bruises which occur when the relay is excited, a flange 30 which is arranged parallel to the axis of the excitation coil 21 and which protrudes slightly from the coil core 22 is arranged on the flange 27 arranged at the free end of the excitation coil 21, so that at Excitation of the relay of the anchor leg 1 25 comes into contact with the neck 30 and dampens the anchor bruises. The approach 30 can be molded in one and the same operation without difficulty in the manufacture of the flange 27.
