Abstract

The relay (1) has a magnetic drive (8) moving a contact spring (4) in respective relay positions. The contact spring closes or interrupts an electric circuit between two relay contacts (2, 3). The magnetic drive has a pole changeable solenoid coil (10) and an armature (12) with a permanent magnet. The armature is tiltably held at the solenoid coil between two switching positions. Two coupling areas are spaced apart from each other, and the armature is engaged with a slidegate valve (17) at the coupling areas towards a pivoting axis (A) for movement coupling of the armature with the valve.

Description

Die Erfindung betrifft ein Relais mit mindestens einer, jeweils den Stromkreis zwischen einem ersten und einem zweiten Relaiskontakt schließenden oder unterbrechenden Kontaktfeder, deren eines Ende leitend mit dem ersten Relaiskontakt verbunden ist und über deren anderes, freies Ende der Stromkreis in einer ersten Relaisposition der Kontaktfeder geschlossen oder in einer zweiten Relaisposition der Kontaktfeder unterbrochen ist, mit einem Magnetantrieb zum Auslenken der mindestens einen Kontaktfeder in die jeweilige Relaisposition, wobei der Magnetantrieb eine umpolbare Magnetspule und einen einen Permanentmagneten aufweisenden Anker aufweist, der an der Magnetspule zwischen zwei Schaltstellungen verschwenkbar gehalten ist, und mit einem in Auslenkrichtung der mindestens einen Kontaktfeder verschiebbaren Schieber, der mit dem Anker bewegungsgekoppelt ist und zwei Mitnehmer aufweist, zwischen denen das freie Ende der mindesten einen Kontaktfeder angeordnet ist.The invention relates to a relay having at least one, in each case the circuit between a first and a second relay contact closing or interrupting contact spring whose one end is conductively connected to the first relay contact and closed via the other, free end of the circuit in a first relay position of the contact spring or in a second relay position of the contact spring is interrupted, with a magnetic drive for deflecting the at least one contact spring in the respective relay position, wherein the magnetic drive comprises a umpolbare magnetic coil and a permanent magnet having an armature, which on the magnetic coil is held pivotably between two switching positions, and with a displaceable in the deflection of the at least one contact spring slide, which is coupled in motion with the armature and has two drivers, between which the free end of the at least one contact spring is arranged.

Ein solches Relais ist beispielsweise durch die DE 101 62 585 C1 bekannt geworden. Bei diesem Relais wird der Stromkreis zwischen zwei elektrischen Relaiskontakten mittels zweier paralleler Kontaktfedern geschlossen oder unterbrochen. Die Kontaktfedern stehen über einen im Relaisgehäuse verschiebbar geführten Schieber in Verbindung mit einem Permanentmagneten eines H-Ankers, der an zwei Jochschenkeln einer Magnetspule schwenkbar gehalten ist. Die Bewegungskopplung des Schiebers mit dem Anker erfolgt mittels eines am Anker vorgesehenen Arms, der mit seinem kugelförmigen freien Ende in eine Lageröffnung des Schiebers eingreift, welcher die Kontaktfedern in und entgegen deren Auslenkrichtung hintergreift. Beim Umpolen der Magnetspule verschwenkt der Permanentmagnet, wodurch der Schieber verschoben und die Kontaktfedern in die jeweils andere Relaisposition ausgelenkt werden. Allerdings kann es vorkommen, dass der Schieber, wenn er durch das kugelförmige freie Ende des Ankers betätigt wird, auf dem kugelförmigen freien Ende, d.h. relativ zum Anker, verkippt. Dies hat zur Folge, dass sich der Schieber in den Führungen des Relaisgehäuses verkantet und sich die beim Schließen des Relais auftretenden Prellzeiten der Kontaktfedern nachteilig verlängern.Such a relay is for example by the DE 101 62 585 C1 known. In this relay, the circuit between two electrical relay contacts by means of two parallel contact springs is closed or interrupted. The contact springs are connected via a slide displaceably guided in the relay housing in conjunction with a permanent magnet of an H-armature, which is held pivotably on two yoke legs of a magnetic coil. The movement coupling of the slide with the armature by means of an arm provided on the arm, which engages with its spherical free end in a bearing opening of the slide, which engages behind the contact springs in and opposite to the deflection. When reversing the polarity of the solenoid pivots the permanent magnet, whereby the slider is moved and the contact springs are deflected into the other relay position. However, it may happen that the slider, when actuated by the spherical free end of the armature, tilts on the spherical free end, ie relative to the armature. This has the consequence that the slider is tilted in the guides of the relay housing and disadvantageously occur during the closing of the relay bounce times of the contact springs.

Es ist die Aufgabe der Erfindung, bei einem Relais der eingangs genannten Art ein Verkanten des Schiebers in seinen Führungen und verlängerte Prellzeiten der Kontaktfedern zu verhindern.It is the object of the invention to prevent tilting of the slide in its guides and extended bounce times of the contact springs in a relay of the type mentioned.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass für die Bewegungskopplung der Anker an mindestens zwei in Richtung seiner Schwenkachse voneinander beabstandeten Kopplungsstellen mit dem Schieber in Eingriff steht.This object is achieved in that is for the motion coupling of the armature at least two spaced apart in the direction of its pivot axis coupling points with the slider in engagement.

Erfindungsgemäß steht der Anker über mindestens eine 2-Punktlagerung mit dem Schieber in Eingriff, der dadurch verkippfest zum Anker gehalten und daher verkantungsfrei in den Führungen des Relaisgehäuses geführt ist.According to the invention, the armature engages via at least one 2-point bearing with the slide, which is thereby held in a tilted manner relative to the armature and therefore guided without tilting in the guides of the relay housing.

Bei einer bevorzugten Ausführungsform der Erfindung sind der Anker und der Schieber über mindestens einen Arm des Ankers miteinander bewegungsgekoppelt, welcher sich in Richtung der Schwenkachse des Ankers erstreckt und an welchem die mindestens zwei voneinander beabstandeten Kopplungsstellen vorgesehen sind.In a preferred embodiment of the invention, the armature and the slide are coupled in motion with each other via at least one arm of the armature, which extends in the direction of the pivot axis of the armature and on which the at least two spaced-apart coupling points are provided.

Bei einer anderen bevorzugten Ausführungsform der Erfindung sind der Anker und der Schieber über mindestens zwei parallele Arme des Ankers miteinander bewegungsgekoppelt, die in Richtung der Schwenkachse des Ankers voneinander beabstandet sind und die jeweils eine Kopplungsstelle ausbilden.In another preferred embodiment of the invention, the armature and the slider are coupled in motion to each other via at least two parallel arms of the armature, which are spaced apart in the direction of the pivot axis of the armature and each forming a coupling point.

Bevorzugt sind mehrere den Stromkreis zwischen den beiden Relaiskontakten jeweils schließende oder unterbrechende parallele Kontaktfedern vorgesehen, die gemeinsam durch den Magnetantrieb in die jeweilige Relaisposition ausgelenkt werden. Die mehreren parallelen Kontaktfedern können beispielsweise separate Kontaktfedern oder eine einzige Mehrlingskontaktfeder mit einem gemeinsamen Befestigungsende und mehreren freien Enden sein.Preferably, a plurality of the circuit between the two relay contacts each closing or interrupting parallel contact springs are provided, which are deflected together by the magnetic drive in the respective relay position. For example, the plurality of parallel contact springs may be separate contact springs or a single multiple contact spring having a common attachment end and a plurality of free ends.

Zur Unterstützung der verkippungsfreien Bewegungskopplung des Schiebers mit dem Anker sind die eine bzw. mehreren parallelen Kontaktfedern und der bzw. die Arme des Ankers zueinander mittig bzw. zentriert zueinander angeordnet.In order to support the tilt-free movement coupling of the slide with the armature, the one or more parallel contact springs and the arm or arms of the armature are arranged centrally relative to each other or centered.

Das in den Fig. 1 dargestellte Relais 1 umfasst zwei Relaiskontakte 2, 3 und drei den Stromkreis zwischen den beiden Relaiskontakten 2, 3 jeweils schließende oder unterbrechende parallele Kontaktfedern 4, welche als elektrisch leitende Blatt- oder Flachfedern (z.B. aus Kupfer) ausgebildet sind. Die einen, in Fig. 1 linken Enden 5 der Kontaktfedern 4 sind elektrisch leitend an dem in Fig. 1 oberen Relaiskontakt 2 befestigt, während die anderen, freien Enden 6 der Kontaktfedern 4 auf ihrer Unterseite jeweils einen Kontaktknopf 7 tragen und gemeinsam mittels eines Magnetantriebs 8 auslenkbar sind. Die Kontaktfedern 4 sind in ihrer in Fig. 1 gezeigten geschlossenen Relaisposition derart nach unten ausgelenkt, dass ihre Kontaktknöpfe 7 jeweils an Kontaktknöpfen 9 des unteren Relaiskontakts 3 anliegen. In der offenen Relaisposition sind die Kontaktfedern 4 derart nach oben ausgelenkt, dass ihre Kontaktknöpfe 7 von den Kontaktknöpfen 9 des unteren Relaiskontakts 3 abgehoben sind.That in the Fig. 1 shown relay 1 comprises two relay contacts 2, 3 and three the circuit between the two relay contacts 2, 3 each closing or interrupting parallel contact springs 4, which are formed as electrically conductive leaf or flat springs (eg made of copper). The one, in Fig. 1 left ends 5 of the contact springs 4 are electrically conductive on the in Fig. 1 fixed upper relay contact 2, while the other, free ends 6 of the contact springs 4 each carry a contact button 7 on its underside and are jointly deflectable by means of a magnetic drive 8 . The contact springs 4 are in their in Fig. 1 shown closed relay position deflected down so that their contact buttons 7 abut respectively on contact buttons 9 of the lower relay contact 3. In the open relay position, the contact springs 4 are deflected upward so that their contact buttons 7 are lifted from the contact buttons 9 of the lower relay contact 3.

Wie in Fig. 2 gezeigt, sind die drei Kontaktfedern 4 an ihren Befestigungsenden 6 miteinander verbunden und bilden somit eine Drillingskontaktfeder.As in Fig. 2 shown, the three contact springs 4 are connected together at their attachment ends 6 and thus form a triplet spring.

Der Magnetantrieb 8 umfasst eine umpolbare Magnetspule 10 mit einem Magnetkreis, an dessen zwei Jochschenkeln 11 ein Magnetanker 12 mit einem Permanentmagneten (nicht gezeigt) schwenkbar um die Schwenkachse A gehalten ist. Der Permanentmagnet ist zwischen zwei Ankerplatten 13 angeordnet, die in den beiden Schaltstellungen des Ankers 12 jeweils an den Jochschenkeln 11 anliegen. Die Magnetspule 10 und der zwischen seinen beiden Schaltstellungen verschwenkbare Ankers 12 bilden einen H-Ankeranzug. Wie in Fig. 3 gezeigt, hat der Anker 12 zwei radial zur Schwenkachse A vorstehende parallele Arme 14a, 14b, die an ihren freien Enden 15a, 15b jeweils kugelförmig ausgebildet und voneinander in Richtung der Schwenkachse A beabstandet sind. Der Anker 12 greift mit seinen beiden vorstehenden Armen 14a, 14b, genauer gesagt mit seinen kugelförmigen Enden 15a, 15b, jeweils in eine Lageröffnung 16 eines Schiebers 17 ein, der im Relaisgehäuse in Auslenkrichtung der Kontaktfeder 5 bzw. parallel zur Achse der Magnetspule 10 linear verschiebbar (Doppelpfeil 18) geführt ist. Die beiden Lageröffnungen 16 sind jeweils mittig zwischen zwei Kontaktfedern 4 angeordnet. Der Anker 12 steht also an zwei in Richtung seiner Schwenkachse A voneinander beabstandeten Kopplungsstellen 15a, 15b mit dem Schieber 17 für die Bewegungskopplung in Eingriff.The magnetic drive 8 comprises a umpolbare magnetic coil 10 with a magnetic circuit, at the two yoke legs 11, a magnet armature 12 (not shown) with a permanent magnet is pivotally held about the pivot axis A. The permanent magnet is arranged between two armature plates 13 , which rest in each case on the yoke legs 11 in the two switching positions of the armature 12. The magnetic coil 10 and the pivotable between its two switching positions armature 12 form a H-anchor suit. As in Fig. 3 has shown that Armature 12 has two parallel to the pivot axis A projecting parallel arms 14a, 14b, which are each formed at their free ends 15a, 15b spherical and spaced from each other in the direction of the pivot axis A. The armature 12 engages with its two projecting arms 14a, 14b, more precisely with its spherical ends 15a, 15b, each in a bearing opening 16 of a slider 17 which in the relay housing in the deflection of the contact spring 5 and parallel to the axis of the solenoid 10 linearly displaceable (double arrow 18 ) is guided. The two bearing openings 16 are each arranged centrally between two contact springs 4. The armature 12 is thus at two in the direction of its pivot axis A spaced-apart coupling points 15a, 15b with the slider 17 for the movement coupling into engagement.

Der am Schieber 17 angelenkte Anker 12 bildet eine Ankerwippe zum Auslenken der Kontaktfedern 4 in ihre geöffnete oder geschlossene Relaisposition. Der Schieber 17 untergreift mit einem unteren Mitnehmer 19 die freien Enden 6 der Kontaktfedern 4 und übergreift mit einem oberen Mitnehmer 20 drei Federstahl-Blattfedern 21, die jeweils oben auf den freien Enden 6 der Kontaktfedern 4 befestigt sind und über die freien Enden 6 der Kontaktfedern 4 vorstehen. Der Schieber 17 nimmt mit seinem unteren Mitnehmer 19 die Kontaktfedern 4 in Öffnungsrichtung des Relais 1, d.h. nach oben, und mit seinem oberen Mitnehmer 20 über die Blattfedern 21 die Kontaktfedern 4 in Schließrichtung des Relais 1, d.h. nach unten, mit. Mit anderen Worten sind die freien Enden 6 der Kontaktfedern 4 mit dem Schieber 17 in Öffnungsrichtung unmittelbar und in Schließrichtung mittels der Blattfedern 21 bewegungsgekoppelt. Die Kontaktfedern 4 sind jeweils als eine mehrlagige Blattfeder ausgebildet, deren beide unteren Lagen jeweils einen seitlich aus ihrer Ebene vorstehenden Bogenabschnitt 22 aufweisen.The hinged to the slide 17 armature 12 forms an armature rocker for deflecting the contact springs 4 in their open or closed relay position. The slider 17 engages with a lower driver 19, the free ends 6 of the contact springs 4 and engages with an upper driver 20 three spring steel leaf springs 21, which are each secured on top of the free ends 6 of the contact springs 4 and the free ends 6 of the contact springs 4 project. The slider 17 takes with its lower driver 19, the contact springs 4 in the opening direction of the relay 1, ie upwards, and with its upper driver 20 via the leaf springs 21, the contact springs 4 in the closing direction of the relay 1, ie down, with. In other words, the free ends 6 of the contact springs 4 are coupled with the slide 17 in the opening direction directly and in the closing direction by means of the leaf springs 21. The contact springs 4 are each formed as a multi-layer leaf spring, the two lower layers each have a laterally projecting from their plane arc section 22 .

Zum Schalten des Relais 1 wird das Magnetfeld der Magnetspule 10 umgepolt, wodurch der Anker 12 verschwenkt und der Schieber 17 verschoben wird. In der in Fig.1 gezeigten geschlossenen Relaisposition ist der Schieber 17 durch die nach unten geschwenkten Arme 14 nach unten verschoben, wodurch über die Blattfedern 21 auch die Kontaktfedern 4 synchron nach unten bis zur Anlage ihrer Kontaktknöpfe 7 an den Kontaktknöpfen 9 der unteren Relaiskontakte 3 ausgelenkt sind. Der Anpressdruck der Kontaktknöpfe 7 an die Kontaktknöpfe 9 der unteren Relaiskontakte 3 ist durch die Druckkraft der vom Schieber 17 zusammengedrückten Blattfedern 21 gegeben. In der geschlossenen Relaisposition wirken die Blattfedern 21 der Auslenkung der Kontaktfedern 4 in Öffnungsrichtung entgegen, was zu einem prellreduzierten Schließen des Relais 1 führt. Durch Umpolen der Magnetspule 10 wird der Anker 12 in entgegen gesetzter Richtung verschwenkt und der Schieber 17 in entgegen gesetzter Richtung verschoben. In der offenen Relaisposition ist der Schieber 17 durch die nach oben geschwenkten Arme 14 nach oben verschoben, wodurch die Kontaktfedern 4 von den unteren Mitnehmern 19 des Schiebers 17 mitgenommen und die Kontaktknöpfe 7 von den Kontaktknöpfen 9 der unteren Relaiskontakte 3 synchron abgehoben sind. Aufgrund der 2-Punktlagerung des Ankers mit dem Schieber 17 ist der Schieber 17 kippfest mit dem Anker 12 verbunden und daher verkantungsfrei in den Führungen des Relaisgehäuses geführt. Zur Unterstützung der verkippungsfreien Bewegungskopplung des Schiebers 17 mit dem Anker 12 sind die beiden Arme 14a, 14b des Ankers 12 jeweils in der Trennebene zwischen zwei Kontaktfedern 4 angeordnet.To switch the relay 1, the magnetic field of the magnetic coil 10 is reversed, whereby the armature 12 is pivoted and the slider 17 is moved. In the in Fig.1 shown closed relay position, the slider 17 is moved downward by the downwardly pivoted arms 14, which are deflected by the leaf springs 21 and the contact springs 4 synchronously down to the contact buttons 7 on the contact buttons 9 of the lower relay contacts 3. The contact pressure of the contact buttons 7 to the contact buttons 9 of the lower Relay contacts 3 is given by the pressure force of the slider 17 compressed leaf springs 21. In the closed relay position, the leaf springs 21 counteract the deflection of the contact springs 4 in the opening direction, which leads to a reduced-rebound closure of the relay 1. By reversing the magnetic coil 10, the armature 12 is pivoted in the opposite direction and the slider 17 is moved in the opposite direction. In the open relay position, the slider 17 is displaced by the upwardly pivoted arms 14 upwards, whereby the contact springs 4 are taken from the lower drivers 19 of the slider 17 and the contact buttons 7 are lifted synchronously from the contact buttons 9 of the lower relay contacts 3. Due to the 2-point bearing of the armature with the slider 17, the slider 17 is kippfest connected to the armature 12 and therefore guided without tilting in the guides of the relay housing. To support the tilt-free movement coupling of the slider 17 with the armature 12, the two arms 14a, 14b of the armature 12 are each arranged in the parting plane between two contact springs 4.

Der in Fig. 4 ist gezeigte Magnetanker 12' weist einen einzigen Arm 14' auf, der in Richtung der Schwenkachse A des Ankers 12' eine Breite B aufweist. Mit dieser Breite B greift das kugelförmig ausgebildete freie Ende 15 des Arms 14' in die entsprechende Lageröffnung (nicht gezeigt) des Schiebers 17 ein. In Fig. 4 sind beispielhaft die beiden seitlichen Enden des freien Endes 15 als zwei in Richtung der Schwenkachse A voneinander beabstandete Kopplungsstelle 14a, 14b des Ankers 12' bezeichnet. Aufgrund der nicht punktuellen Lagerung des Ankers 12' mit dem Schieber 17 ist der Schieber 17 kippfest mit dem Anker 12' verbunden und daher verkantungsfrei in den Führungen des Relaisgehäuses geführt.The in Fig. 4 shown armature 12 ' has a single arm 14' , which has a width B in the direction of the pivot axis A of the armature 12 '. With this width B engages the spherical shaped free end 15 of the arm 14 'in the corresponding bearing opening (not shown) of the slider 17 a. In Fig. 4 are exemplified the two lateral ends of the free end 15 as two in the direction of the pivot axis A spaced-apart coupling point 14a, 14b of the armature 12 '. Due to the non-point storage of the armature 12 'with the slider 17, the slider 17 is kippfest connected to the armature 12' and therefore guided without tilting in the guides of the relay housing.
