Description

Die vorliegende Erfindung betrifft ein Relais mit mindestens einer, den Stromkreis zwischen zwei Relaiskontakten schließenden oder unterbrechenden elektrisch leitenden Kontaktbrücke und mit einem Magnetantrieb, der eine umpolbare Magnetspule und eine einen Permanentmagneten aufweisende Ankerwippe aufweist, welche an der Magnetspule zwischen zwei Endstellungen verschwenkbar gehalten istThe present invention relates to a relay having at least one, the circuit between two relay contacts closing or interrupting electrically conductive contact bridge and a magnetic drive having a umpolbare magnetic coil and a permanent magnet having rocker arm, which is held pivotably on the magnetic coil between two end positions

Ein derartiges Relais mit Drehankerwippe ist beispielsweise durch die DE 101 62 585 C1 oder DE 102 49 697 B3 bekannt geworden.Such a relay with rotary anchor rocker is for example by the DE 101 62 585 C1 or DE 102 49 697 B3 known.

Bei diesen bekannten Relais wird ein Stromkreis zwischen zwei elektrischen Relaiskontakten mittels einer oder mehrerer Kontaktfedern geschlossen oder unterbrochen. Die Kontaktfedern stehen über ein verschiebbares Stellelement in Verbindung mit einem Permanentmagneten eines H-Ankers (Drehankerwippe), der an zwei Jochschenkeln einer Magnetspule schwenkbar gehalten ist. Beim Umpolen der Magnetspule verschwenkt der Permanentmagnet, wodurch das Stellelement verschoben wird. Da das Stellelement die Kontaktfedern in deren Auslenkrichtung hintergreift, werden diese dabei aus ihrer geschlossenen Ruhelage ausgelenkt, so dass der Stromkreis unterbrochen ist.In these known relays a circuit between two electrical relay contacts is closed or interrupted by means of one or more contact springs. The contact springs are connected via a displaceable actuating element in conjunction with a permanent magnet of a H-armature (rocker arm rocker), which is pivotally supported on two yoke legs of a magnetic coil. When reversing the magnetic coil pivots the permanent magnet, whereby the actuator is moved. Since the actuating element engages behind the contact springs in their deflection direction, they are thereby deflected out of their closed rest position so that the circuit is interrupted.

Es ist demgegenüber die Aufgabe der vorliegenden Erfindung, bei einem Relais der eingangs genannten Art die beweglichen Teile weiter zu reduzieren.It is the object of the present invention to further reduce the moving parts in a relay of the type mentioned.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Kontaktbrücke an der Ankerwippe vorgesehen ist und in der einen, geschlossenen Endstellung der Ankerwippe an beiden Relaiskontakten elektrisch leitend anliegt und in der anderen, offenen Endstellung der Ankerwippe von mindestens einem der beiden Relaiskontakte abgehoben ist.This object is achieved in that the contact bridge is provided on the armature rocker and electrically conductive in one, closed end position of the armature rocker on both relay contacts and is lifted in the other, open end position of the armature rocker of at least one of the two relay contacts.

Erfindungsgemäß ist also kein zusätzliches geführtes Stellelement zur Übertragung der Drehbewegung der Ankerwippe auf die Kontaktbrücke erforderlich, sondern die an der Ankerwippe starr angeordnete Kontaktbrücke verschwenkt zusammen mit der Ankerwippe und schließt oder unterbricht die Relaiskontakte.According to the invention therefore no additional guided actuator for transmitting the rotational movement of the armature rocker on the contact bridge is required, but the rigidly arranged on the armature rocker contact bridge pivoted together with the armature rocker and closes or interrupts the relay contacts.

In einer bevorzugten Ausführungsform ist die mindestens eine Kontaktbrücke an einem bezüglich der Schwenkachse der Ankerwippe radial vorstehenden Arm der Ankerwippe vorgesehen. In einer anderen bevorzugten Ausführungsform ist die mindestens eine Kontaktbrücke in einer Axialebene der Schwenkachse angeordnet.In a preferred embodiment, the at least one contact bridge is provided on a relative to the pivot axis of the armature rocker radially projecting arm of the armature rocker. In another preferred embodiment, the at least one contact bridge is arranged in an axial plane of the pivot axis.

Besonders bevorzugt ist an den beiden Relaiskontakten jeweils eine Blattfeder elektrisch leitend befestigt, wobei die mindestens eine Kontaktbrücke in der geschlossenen Endstellung der Ankerwippe an den freien Enden der Blattfedern, diese auslenkend, elektrisch leitend anliegt und in der offenen Endstellung der Ankerwippe von mindestens einer der beiden Blattfedern, vorzugsweise von beiden Blattfedern, abgehoben ist. Die Kontaktkraft wird durch die vorgespannte Blattfeder generiert, die durch die Ankerwippe ausgelenkt wird. Ein gehäuseseitiger Anschlag hält die Blattfeder in Position, damit die Vorspannung gehalten wird und ein definierter Kontaktabstand gehalten werden kann.Particularly preferably, a leaf spring is electrically conductively attached to the two relay contacts, wherein the at least one contact bridge in the closed end position of the armature rocker at the free ends of the leaf springs, this deflecting, electrically conductive abuts and in the open end position of the armature rocker of at least one of the two Leaf springs, preferably from both leaf springs, lifted is. The contact force is generated by the prestressed leaf spring, which is deflected by the anchor rocker. A housing-side stop holds the leaf spring in position so that the bias is maintained and a defined contact spacing can be maintained.

Vorzugsweise übergreifen die Blattfedern mit ihren freien Enden ihren jeweiligen Relaiskontakt in entgegengesetzter Richtung, um eine zickzackförmige Anordnung auszubilden. Bei Stromfluss (Kurzschlussfall) wird die auf die Kontaktbrücke wirkende Kontaktkraft durch die magnetische Abstoßungskraft erhöht, die vom Magnetfeld der stromdurchflossenen Relaiskontakte auf ihre jeweils in Gegenrichtung stromdurchflossenen Blattfedern ausgeübt wird.Preferably, the leaf springs engage with their free ends their respective relay contact in the opposite direction to form a zigzag arrangement. When there is a current flow (short-circuiting case), the contact force acting on the contact bridge is increased by the magnetic repulsive force exerted by the magnetic field of the relay contacts through which current flows in the opposite direction.

Vorzugsweise ist die Kontaktbrücke steckbar, rastbar oder als Kunststoff-Einlegeteil mit der Ankerwippe verbunden.Preferably, the contact bridge is pluggable, latched or connected as a plastic insert with the anchor rocker.

Ebenso können die vorstehend genannten und die noch weiter aufgeführten Merkmale je für sich oder zu mehreren in beliebigen Kombinationen Verwendung finden.

Fign.3 to 5 Further embodiments of an anchor rocker with contact bridge in a plan view ( FIGS. 3a to 5a ) and in a perspective view ( FIGS. 3b to 5b ).

Das in Fig. 1a und 1b gezeigte Relais 1 weist zwei Relaiskontakte 2, 3, eine dazwischen schwenkbar angeordnete Kontaktbrücke 4 zum Schließen oder Unterbrechen des Stromkreises zwischen den beiden Relaiskontakten 2, 3 sowie einen Magnetantrieb 5 zum Verschwenken der Kontaktbrücke 4 auf.This in Fig. 1a and 1b shown relay 1 has two relay contacts 2, 3, a pivotally arranged therebetween contact bridge 4 for closing or interrupting the circuit between the two relay contacts 2, 3 and a magnetic drive 5 for pivoting the contact bridge 4.

Der Magnetantrieb 5 umfasst eine umpolbare Magnetspule 6 mit einem Magnetkreis, an dessen zwei Jochschenkeln 7 eine Drehankerwippe 8 mit einem Permanentmagneten (nicht gezeigt) schwenkbar um die Schwenkachse 9 gehalten ist. Der Permanentmagnet ist zwischen zwei Ankerplatten 10 angeordnet, die in den beiden Endstellungen der Ankerwippe 8 jeweils an den Jochschenkeln 7 anliegen. Die Magnetspule 6 und die zwischen ihren beiden Endstellungen verschwenkbare Ankerwippe 8 bilden einen H-Ankeranzug. Die Ankerwippe 8 hat einen bezüglich der Schwenkachse 9 radial vorstehenden Arm 11, der an seinem freien Ende die Ankerwippe 8 trägt.The magnetic drive 5 comprises a umpolbare magnetic coil 6 with a magnetic circuit, on whose two yoke legs 7 a rotary armature rocker 8 with a permanent magnet (not shown) is pivotally held about the pivot axis 9. The permanent magnet is arranged between two anchor plates 10 , which rest in the two end positions of the armature rocker 8 in each case on the yoke legs 7. The magnetic coil 6 and the pivotable between its two end positions anchor rocker 8 form a H-anchor suit. The armature rocker 8 has a respect to the pivot axis 9 radially projecting arm 11 which carries the armature rocker 8 at its free end.

Wie in Fig. 2 gezeigt, weist die Kontaktbrücke 4 weist zwei Kontaktknöpfe 12 auf, die zu beiden Seiten des Arms 11, aber auf unterschiedlichen Seiten der Kontaktbrücke 4 angeordnet und durch eine Kupferbahn 13 miteinander elektrisch verbunden sind. Die beiden Kontaktknöpfe 12 sind außerdem in Richtung der Schwenkachse 9 querbeabstandet zueinander angeordnet. Die Kontaktbrücke 4 ist mit der Ankerwippe 8 steckbar oder rastbar verbunden oder als einstückiges Kunststoffspritzteil mit der Kupferbahn 13 und deren Kontaktknöpfen 12 als Einlegeteil gefertigt. Die Ankerwippe 8 ist über zwei vorstehende Lagerzapfen 14 im Relaisgehäuse 15 um die Schwenkachse 9 gelagert.As in Fig. 2 shown, the contact bridge 4 has two contact buttons 12 , which are arranged on both sides of the arm 11, but on different sides of the contact bridge 4 and electrically connected to each other by a copper track 13 . The two contact buttons 12 are also arranged transversely spaced from one another in the direction of the pivot axis 9. The contact bridge 4 is plugged or latchably connected to the armature rocker 8 or manufactured as a one-piece plastic injection molded part with the copper sheet 13 and the contact buttons 12 as an insert. The armature rocker 8 is mounted about two pivot pins 14 in the relay housing 15 about the pivot axis 9.

Die beiden Relaiskontakte 2, 3 sind zwei Kupferkontakte, die an ihren einander gegenüberliegenden Kontaktenden 2a, 3a im Relaisgehäuse 15 befestigt sind und deren freie Kontaktenden 2b, 3b parallel und in Richtung der Schwenkachse 9 querbeabstandet zueinander verlaufen und einander übergreifen. Im Ausführungsbeispiel der Fig. 1 erstreckt sich der Arm 11 in einer Radialebene zwischen den beiden freien Kontaktenden 2b, 3b der beiden Relaiskontakten 2, 3. An diesen freien Kontaktenden 2b, 3b ist jeweils eine Blattfeder 16 elektrisch leitend befestigt, die an ihrem freien Ende einen Kontaktknopf 17 zur Anlage am Kontaktknopf 12 der Kontaktbrücke 4 aufweist. Die Blattfedern 16 übergreifen mit ihren freien Enden ihren jeweiligen Relaiskontakt 2, 3 in entgegengesetzter Richtung, so dass die Relaiskontakte 2, 3 zusammen mit den Blattfedern 16 und der Kontaktbrücke 4 eine zickzackförmige Anordnung bilden.The two relay contacts 2, 3 are two copper contacts , which are fixed at their opposite contact ends 2a, 3a in the relay housing 15 and the free contact ends 2b, 3b parallel and in the direction of the pivot axis 9 transverse to each other and overlap each other. In the embodiment of Fig. 1 extends the arm 11 in a radial plane between the two free contact ends 2b, 3b of the two relay contacts 2, 3. At these free contact ends 2b, 3b, a leaf spring 16 is electrically conductively attached, at its free end a contact button 17 to rest on Contact button 12 of the contact bridge 4 has. The leaf springs 16 engage with their free ends their respective relay contact 2, 3 in the opposite direction, so that the relay contacts 2, 3 together with the leaf springs 16 and the contact bridge 4 form a zigzag arrangement.

In Fig. 1a ist das Relais 1 in seiner offenen Relaisposition gezeigt, in der die Kontaktwippe 8 in ihre eine Endstellung verschwenkt ist und dadurch die Kontaktbrücke 4 mit ihren beiden Kontaktknöpfen 12 von den Kontaktknöpfen 17 der Blattfedern 16 abgehoben ist und somit die beiden Relaiskontakte 2, 3 nicht miteinander elektrisch verbindet. In dieser offenen Relaisposition liegen die freien Enden der Blattfedern 16 jeweils mit Vorspannung an einem gehäuseseitigen Anschlag 18 an, der auch einen definierten Kontaktabstand zwischen Kontaktbrücke 4 und Blattfeder 16 vorgibt. In Fig. 1b ist das Relais 1 in seiner geschlossenen Relaisposition gezeigt, in der die Kontaktbrücke 4 mit ihren beiden Kontaktknöpfen 12 an den Kontaktknöpfen 17 der Blattfedern 16 anliegt und somit die beiden Relaiskontakte 2, 3 miteinander elektrisch verbindet. In dieser geschlossenen Relaisposition sind die Blattfedern 16 durch die Kontaktbrücke 4 ausgelenkt und vom Anschlag 18 abgehoben. Der Anpressdruck zwischen den Kontaktknöpfen 12 und 17 ist durch die Vorspannungskraft der von der Kontaktbrücke 4 ausgelenkten Blattfedern 16 gegeben, sowie bei Stromfluss (Kurzschlussfall) zusätzlich durch die magnetische Abstoßungskraft, die vom Magnetfeld der stromdurchflossenen Relaiskontakte 2, 3 auf ihre jeweils in Gegenrichtung stromdurchflossenen Blattfedern 16 ausgeübt wird. Diese magnetische Kontaktkraft ist umso größer, je höher die Stromstärke und je geringer der Abstand zwischen Relaiskontakt 2, 3 und Blattfeder 16 ist.In Fig. 1a the relay 1 is shown in its open relay position, in which the contact rocker 8 is pivoted into its one end position and thereby the contact bridge 4 with its two contact buttons 12 is lifted from the contact buttons 17 of the leaf springs 16 and thus the two relay contacts 2, 3 not together connects electrically. In this open relay position, the free ends of the leaf springs 16 are each biased against a housing-side stop 18 , which also defines a defined contact distance between contact bridge 4 and leaf spring 16. In Fig. 1b the relay 1 is shown in its closed relay position, in which the contact bridge 4 rests with its two contact buttons 12 on the contact buttons 17 of the leaf springs 16 and thus electrically connects the two relay contacts 2, 3 together. In this closed relay position, the leaf springs 16 are deflected by the contact bridge 4 and lifted from the stop 18. The contact pressure between the contact buttons 12 and 17 is given by the biasing force of the contact bridge 4 deflected leaf springs 16, and in current flow (short circuit case) in addition by the magnetic repulsion force from the magnetic field of the current-carrying relay contacts 2, 3 on their respective current in the opposite direction leaf springs 16 is exercised. This magnetic contact force is greater, the higher the current intensity and the smaller the distance between relay contact 2, 3 and leaf spring 16.

Zum Umschalten des Relais 1 wird das Magnetfeld der Magnetspule 6 umgepolt, wodurch der Permanentmagnet und die Ankerwippe 4 in ihre jeweils andere Endstellung und dadurch auch die Kontaktbrücke 4 verschwenkt wird.To switch the relay 1, the magnetic field of the magnetic coil 6 is reversed, whereby the permanent magnet and the armature rocker 4 is pivoted into its respective other end position and thereby also the contact bridge 4.

Die Fign.3 bis 5 zeigen die Ankerwippe 8 mit jeweils modifizierten Kontaktbrücken 4. Die in Fig. 3 gezeigte Kontaktbrücke 4 weist vier Kontaktknöpfe 12 -jeweils zwei zu beiden Seiten des Arms 11 und auf unterschiedlichen Seiten der Kontaktbrücke 4 - auf, wobei alle Kontaktknöpfe 12 durch die Kupferbahn 13 miteinander elektrisch verbunden sind. Diese Kontaktbrücke 4 dient zum Schließen oder Unterbrechen des gleichen Stromkreises.The Fign.3 to 5 show the armature rocker 8, each with modified contact bridges 4. The in Fig. 3 shown contact bridge 4 has four contact buttons 12 - each two on both sides of the arm 11 and on different sides of the contact bridge 4 - on, with all the contact buttons 12 are electrically connected to each other by the copper track 13. This contact bridge 4 is used to close or interrupt the same circuit.

Von der Kontaktbrücke der Fig. 3 unterscheidet sich die in Fig. 4 gezeigte Kontaktbrücke 4 dadurch, dass hier zwei Kontaktbrücken 4a, 4b mit zwei Kupferbahnen 13a, 13b vorgesehen sind, durch die jeweils zwei Kontaktknöpfe 12 miteinander elektrisch verbunden sind. Diese Kontaktbrücken 4 dienen zum Schließen oder Unterbrechen des gleichen Stromkreises oder zweier unterschiedlicher Stromkreise.From the contact bridge of Fig. 3 is different in the Fig. 4 shown contact bridge 4 in that here two contact bridges 4a, 4b are provided with two copper tracks 13a, 13b , through which two contact buttons 12 are electrically connected to each other. These contact bridges 4 are used to close or interrupt the same circuit or two different circuits.

Von der Kontaktbrücke der Fig. 3 unterscheidet sich die in Fig. 5 gezeigte Kontaktbrücke 4 dadurch, dass hier die Ankerwippe 8 keinen vorstehenden Arm aufweist und die Kontaktbrücke 4 in einer Axialebene der Schenkachse 9 und zu beiden axialen Seiten der Ankerwippe 8 vorgesehen ist. Diese Kontaktbrücke 4 mit ihrer einen Kupferbahn 13 dient zum Schließen oder Unterbrechen des gleichen Stromkreises.From the contact bridge of Fig. 3 is different in the Fig. 5 shown contact bridge 4 in that here the armature rocker 8 has no protruding arm and the contact bridge 4 is provided in an axial plane of the pivot axis 9 and on both axial sides of the armature rocker 8. This contact bridge 4 with its one copper track 13 serves to close or interrupt the same circuit.
