Description

Die Erfindung bezieht sich auf ein Relais mit einem aus einem Joch und einem Anker bestehenden Magnetsystem, bei dem der Anker an dem Joch gelagert ist und einer Spule, wobei der Anker und das Joch mit einem Schenkel in die Spule eingreifen.The invention relates to a relay with a magnet system consisting of a yoke and an armature, in which the armature is mounted on the yoke and a coil, the armature and the yoke engaging with one leg in the coil.

Ein solches Relais wurde z.B. durch die EU B1 70 717 bekannt. Bei diesem bekannten Relais besteht das Joch aus zwei im Querschnitt U-förmigen Teilen, deren Schenkel ungleich lang sind. Die längeren Schenkel des Joches sind dabei an der Außenseite der Spule miteinander verbunden, wobei die Schenkel der Jochteile in deren Verbindungsbereich nur die halbe Dicke aufweisen und flächig aneinander liegen. Trotz der relativ großen Berührungsflächen der beiden Jochteile erfordert der zwischen diesen verbleibende Luftspalt eine entsprechende Magnetisierung, die durch die Spule aufgebracht werden muß.Such a relay was e.g. known by the EU B1 70 717. In this known relay, the yoke consists of two parts with a U-shaped cross section, the legs of which are of unequal length. The longer legs of the yoke are connected to one another on the outside of the coil, the legs of the yoke parts in their connecting area being only half the thickness and lying flat against one another. Despite the relatively large contact surfaces of the two yoke parts, the air gap remaining between them requires a corresponding magnetization, which must be applied by the coil.

Die kürzeren Schenkel der beiden Jochteile greifen dabei in das Innere der Spule ein, wobei zwischen den einander zugekehrten Stirnseiten der in die Spule eingreifenden Schenkel des Joches ein relativ großer Luftspalt verbleibt.The shorter legs of the two yoke parts engage in the interior of the coil, a relatively large air gap remaining between the mutually facing end faces of the legs of the yoke engaging in the coil.

Der Anker ist an einer Feder gehalten und liegt bei dem bekannten Relais im abgefallenen Zustand im Inneren der Spule an dem kürzeren Schenkel des einen Teiles des Joches mit einer Kante an und ist so bemessen, daß er sich über die Ränder des Luftspaltes zwischen den einander zugekehrten Stirnseiten der beiden Teile des Joches hinaus erstreckt.The armature is held on a spring and is in the known relay in the dropped state inside the coil on the shorter leg of one part of the yoke with an edge and is dimensioned so that it faces over the edges of the air gap between the two End faces of the two parts of the yoke extends beyond.

Der Nachteil dieser bekannten Lösung liegt darin, daß sich aufgrund des zweigeteilten Joches insgesamt drei Luftspalte ergeben, u.zw. zwischen den beiden Teilen das Joches, und an zwei Stellen zwischen dem Joch und dem Anker. Außerdem besteht das Magnetgestell eben aus drei Teilen, die entsprechend hergestellt werden müssen, wobei besonders die Verminderung der Dicke der beiden längeren Schenkel in deren Verbindungsbereich gewisse Probleme und Kosten verursacht. Außerdem erfordert auch der Zusammenbau eines solchen Relais einen entsprechenden Montageaufwand.The disadvantage of this known solution is that a total of three air gaps result due to the yoke divided in two, and so on. the yoke between the two parts, and in two places between the yoke and the anchor. In addition, the magnetic frame consists of three parts that have to be produced accordingly, the reduction in the thickness of the two longer legs in their connection area in particular causing certain problems and costs. In addition, the assembly of such a relay requires a corresponding assembly effort.

Aufgabe der Erfindung ist es, ein Relais der eingangs erwähnten Art vorzuschlagen, das sich einfacher herstellen läßt. Desweiteren hat es sich die Erfindung auch zur Aufgabe gestellt, gegenüber dem Stand der Technik ein Relais zu schaffen, das mit einer geringeren Anzahl von Einzelteilen realisiert werden kann. Ein weiteres Ziel der Erfindung kann auch darin bestehen, daß die beweglichen Teile mit geringem Spiel behaftet sind.The object of the invention is to propose a relay of the type mentioned, which is easier to manufacture. Furthermore, the invention has also set itself the task of creating a relay compared to the prior art, which can be realized with a smaller number of individual parts. Another object of the invention can also be that the moving parts have little play.

Bei einem Relais der eingangs genannten Art besteht die Erfindung darin, daß der Anker L-förmig ausgebildet ist und mit seinem kürzeren Schenkel an dem längeren an der Außenseite der Spule verlaufenden Schenkel des U-förmigen, einstückig ausgebildeten Joches gelagert ist, wobei der kürzere Schenkel des Joches in das Innere der Spule eingreift.In a relay of the type mentioned, the invention is that the armature is L-shaped and is mounted with its shorter leg on the longer leg of the U-shaped, integrally formed yoke running on the outside of the coil, the shorter leg of the yoke engages in the interior of the coil.

Durch diese Maßnahmen ist sichergestellt, daß mit einem lediglich zweiteiligen Magnetgestell das Auslangen gefunden wird, wobei sich lediglich zwei Luftspalte ergeben, u.zw. zwischen dem längeren Schenkel des Ankers und dem ins Innere der Spule hineinragenden Schenkel des Joches und dem zweiten Schenkel des Joches und dem kürzeren Schenkel des Ankers. Dadurch ergibt sich, verglichen mit der vorbekannten Lösung eine Verminderung des Magentisierungsaufwandes.These measures ensure that with just a two-part magnetic frame, sufficiency is found, with only two air gaps, etc. between the longer leg of the armature and the leg of the yoke projecting into the interior of the coil and the second leg of the yoke and the shorter leg of the armature. This results in a reduction in the amount of magentization compared to the previously known solution.

Außerdem ergibt sich bei der erfindungsgemäßen Lösung auch der Vorteil einer einfacheren Montage dieses Relais aufgrund der geringeren Anzahl von Teilen. Weiters läßt sich ein Joch, wie es nach der Erfindung vorgesehen ist, auch einfacher herstellen, da es dazu lediglich notwendig ist einen entsprechend zugeschnittenen Blechstreifen U-förmig zu biegen, was auch im Falle der bekannten Lösung, allerdings bei zwei Teilen pro Relais erforderlich ist.In addition, the solution according to the invention also has the advantage of simpler assembly of this relay due to the smaller number of parts. Furthermore, a yoke, as provided according to the invention, can also be produced more easily, since it is only necessary to bend a correspondingly cut sheet metal strip in a U-shape, which is also necessary in the case of the known solution, but with two parts per relay .

In Weiterbildung der Erfindung kann so vorgegangen werden, daß der längere Schenkel des Ankers durch Abstützung an der Innenwand der Spule bzw. des Spulenkörpers als doppelarmiger Hebel ausgebildet ist. Hiedurch ist es in einfacher Weise für ein Arbeitskontakt-Relais möglich, den erforderlichen Ankerlagerdruck am Joch zu realisieren, insbesondere erübrigt sich aber hiedurch eine gesonderte Ankerfeder.In a further development of the invention, the procedure can be such that the longer leg of the armature is designed as a double-armed lever by being supported on the inner wall of the coil or of the coil body. In this way, it is possible in a simple manner for a normally open contact relay to implement the required armature bearing pressure on the yoke, but in particular there is no need for a separate armature spring.

Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß der Anker mit der von der Stirnseite der Spule abgekehrten Kante am Joch gelagert ist.According to a further feature of the invention it can be provided that the armature is mounted on the yoke with the edge facing away from the end face of the coil.

Dadurch ergibt sich eine sehr einfache Lagerung des Ankers.This results in very simple storage of the armature.

In weiterer Ausgestaltung der Erfindung ist es auch möglich, die Stirnseite des kürzeren Schenkels des Ankers bombiert auszubilden.In a further embodiment of the invention, it is also possible for the end face of the shorter arm of the armature to be curved.

Grundsätzlich wäre es auch möglich den Anker mit der der Stirnseite der Spule zugekehrten Kante des kürzeren Schenkels zu lagern, wobei dann auch die Möglichkeit besteht, die Stirnseite des Schenkels des Ankers in einem solchen Winkel zur Achse des Schenkels anzuordnen, daß dessen Stirnseite bei abgefallenem Anker flächig an dem Joch anliegt.In principle, it would also be possible to mount the armature with the edge of the shorter leg facing the end face of the coil, it then also being possible to arrange the end face of the leg of the armature at such an angle to the axis of the leg that its end face when the armature has fallen off lies flat against the yoke.

Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß der Anker mit seinem kürzeren Schenkel in eine Vertiefung des an der Außenseite der Spule verlaufenden Schenkels eingreift.According to a further feature of the invention it can be provided that the armature engages with its shorter leg in a recess of the leg running on the outside of the coil.

Auf diese Weise ergibt sich eine eindeutige Festlegung des Ankers an dem Joch.In this way, the armature is clearly fixed to the yoke.

Eine andere Möglichkeit der Lagerung des Ankers besteht darin, daß der Anker mit seinem kürzeren Schenkel in Wänden eines Gehäuses gelagert ist, wobei vom kürzeren Schenkel des Ankers Vorsprünge seitlich abstehen, die in Vertiefungen der Wände des Gehäuses eingreifen.Another possibility of mounting the armature is that the armature is mounted with its shorter leg in the walls of a housing, with projections projecting laterally from the shorter arm of the armature, which engage in recesses in the walls of the housing.

Bei dieser Variante ergibt sich der Vorteil, daß an dem Joch keine Vertiefungen eingeprägt werden müssen, sondern diese einfach in dem durch Spritzgießen hergestellten Gehäuse angebracht werden. Zufolge der seitlich abstehenden Vorsprünge kann das Spiel entsprechend gering gehalten werden.This variant has the advantage that no depressions have to be impressed on the yoke, but that they are simply made in the housing produced by injection molding. Due to the protrusions protruding to the side, the game can be kept correspondingly low.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß der kürzere Schenkel des Ankers eine Breite aufweist, die zumindest gleich der Breite des an der Außenseite der Spule verlaufenden Schenkels des Joches ist, wobei die Breite dieses Schenkels des Joches größer als die Breite des in das Innere der Spule eingreifenden Schenkels des Ankers ist.According to a further feature of the invention it is provided that the shorter leg of the armature has a width which is at least equal to the width of the leg of the yoke running on the outside of the coil, the width of this leg of the yoke being greater than the width of the in the Inside the coil engaging leg of the armature is.

Durch diese Maßnahmen ist sichergestellt, daß sich bei dem unvermeidlichen Luftspalt zwischen Joch und Anker ein nur geringer magnetischer Widerstand ergibt und größere Streuungsverluste vermieden werden, wodurch mit einer entsprechend geringen Durchflutung das Auslangen gefunden werden kann.These measures ensure that the inevitable air gap between the yoke and armature results in only a low magnetic resistance and larger scattering losses are avoided, which can be achieved with a correspondingly low flow.

Nach einem weiteren Merkmal der Erfindung kann vorgesehens sein, daß der Anker mittels einer an diesem und dem außen an der Spule gelegenen Schenkel des Joches angreifenden Feder mit seinem kürzeren Schenkel gegen den Schenkel des Joches gedrückt ist.According to a further feature of the invention it can be provided that the armature is pressed with its shorter leg against the leg of the yoke by means of a spring engaging on this and the leg of the yoke located on the outside of the coil.

Darüberhinaus ist die Realisierung eines Umschaltkontaktrelais möglich, wobei ein entsprechend dichtes Anliegen des kürzeren Schenkels des Ankers am Joch sichergestellt wird.In addition, it is possible to implement a changeover contact relay, ensuring that the shorter arm of the armature lies tightly against the yoke.

Dabei ergibt sich eine besonders einfache Lösung, wenn die Feder als U-förmig gebogene Blattfeder ausgebildet ist, die den längeren Schenkel des Joches und den kürzeren Schenkel des Ankers zumindest teilweise umgreift.This results in a particularly simple solution if the spring is designed as a U-shaped leaf spring which at least partially encompasses the longer leg of the yoke and the shorter leg of the armature.

Das Joch 1 ist U-förmig ausgebildet, wobei jedoch der in das Innere der Spule 2 eingreifende Schenkel 3 kürzer als der an der Außenseite der Spule 2 verlaufende Schenkel 4 ist, dessen freies Ende über die Stirnseite 5 der Spule 2, bzw. deren Spulenkörper 6 hinausragt. Dabei weist der in die Spule 2 eingreifende Schenkel 3 des Joches 1 eine geringere Breite als der an der Außenseite der Spule 2 verlaufende Schenkel 4 auf.The yoke 1 is U-shaped, but the leg 3 engaging in the interior of the coil 2 is shorter than the leg 4 running on the outside of the coil 2, the free end of which leg extends over the end face 5 of the coil 2, or its coil former 6 protrudes. The leg 3 of the yoke 1 engaging in the coil 2 has a smaller width than the leg 4 running on the outside of the coil 2.

In diesem über die Stirnseite der Spule 2 vorragenden Bereich des Schenkels 4 des Joches 1 ist der Anker 7, der L-förmig ausgebildet ist, mit seinem kürzeren Schenkel 8 gelagert, wobei die Art der Lagerung vielfältig gewählt werden kann. Bei dem in der Fig. 1 dargestellten Ausführungsbeispiel ist der kürzere Schenkel 8 des Ankers 7 mit seiner von der Stirnseite 5 der Spule 2 abgekehrten Kante 10 an dem Joch 1 gelagert.In this region of the leg 4 of the yoke 1 projecting over the end face of the coil 2, the armature 7, which is L-shaped, is mounted with its shorter leg 8, the type of mounting being able to be varied. At In the embodiment shown in FIG. 1, the shorter leg 8 of the armature 7 is supported on the yoke 1 with its edge 10 facing away from the end face 5 of the coil 2.

Der längere Schenkel 9 des Ankers 7 durchsetzt das Innere der Spule 2. Dabei entspricht die Breite des längeren Schenkels 9 des Ankers 7 und die Breite des in das Innere der Spule 2 eingreifenden Schenkels 3 des Joches 1 der lichten Breite des Inneren der Spule, wobei selbstverständlich ein entsprechendes Spiel vorgesehen ist. Dabei weist der kürzere Schenkel 8 eine die Breite des längeren Schenkels 9 übersteigende Breite auf, die jener der Breite des längeren, an der Außenseite der Spule 2 verlaufenden Schenkels 4 des Joches 1 entspricht.The longer leg 9 of the armature 7 passes through the interior of the coil 2. The width of the longer leg 9 of the armature 7 and the width of the leg 3 of the yoke 1 engaging in the interior of the coil 2 corresponds to the clear width of the interior of the coil, wherein of course, a corresponding game is provided. The shorter leg 8 has a width exceeding the width of the longer leg 9, which corresponds to that of the width of the longer leg 4 of the yoke 1 extending on the outside of the coil 2.

An dem eine geringere Dicke aufweisenden Bereich des längeren Schenkels 9 des Ankers 7 kann ein entsprechendes Übertragungsglied zur Betätigung des in der Fig. 1 nicht dargestellten Kontaktfedernsatzes angreifen.A corresponding transmission element for actuating the contact spring set, not shown in FIG. 1, can act on the region of the longer leg 9 of the armature 7 which has a smaller thickness.

Bei den Relais nach der Fig. 2 und 3 ist der Anker 7 mit seitlich von dessen kürzerem mit bombierten Stirnseiten 25 ausgebildeten Schenkel 8 abstehenden Vorsprüngen 11 versehen, die zueinander koaxial angeordnet sind und in Vertiefungen 12 eines die Spule 2 teilweise umgebenden Gehäuses 13 eingreifen, an dem die Ausleitungen der Spule 2 seitlich vorbeigeführt und mit Anschlußstiften 14 verbunden sind.2 and 3, the armature 7 is provided with projections 11 projecting laterally from its shorter leg 8 formed with cambered end faces 25, which are arranged coaxially with one another and engage in recesses 12 of a housing 13 partially surrounding the coil 2, at which the reels of the coil 2 are passed laterally and are connected to connecting pins 14.

Der ebenfalls mit Anschlußstiften 16 versehene Kontaktfedersatz 17 ist in einem mit dem Gehäuse 13 verbundenem Rahmen 18 gehalten. Betätigt wird dabei die bewegliche Kontaktfeder 19 mittels eines in Bohrungen des Ankers 7 eingreifenden Übertragungsgliedes 20. Weiters ist ein das Relais umgebender Deckel 21 vorgesehen.The contact spring set 17, also provided with connecting pins 16, is held in a frame 18 connected to the housing 13. The movable contact spring 19 is actuated by means of a transmission element 20 which engages in bores of the armature 7. Furthermore, a cover 21 surrounding the relay is provided.

Bei dem mit einem Arbeitskontakt ausgebildeten Relais nach Fig. 2 stützt sich der längere Schenkel 9 des Ankers 7 an der Innenwand der Spule 2, bzw. des Spulenkörpers, ab; der Abstützpunkt stellt einen Dreh- bzw. Kippunkt 22 dar. Solcherart ist dieser längere Schenkel 9 des Ankers 7 als doppelarmiger Hebel ausgebildet.2, the longer leg 9 of the armature 7 is supported on the inner wall of the coil 2 or the coil body; the support point represents a pivot point 22. Such a longer leg 9 of the armature 7 is designed as a double-armed lever.

Die Kraft der beweglichen, in Richtung Spule vorgespannten Kontaktfeder 19 wird über das Übertragungsglied 20 und den Drehpunkt 22 übersetzt und wirkt so auf den Anker 7, daß dieser mit seinem kürzeren Schenkel 8 in die Ankerlagerung im Joch gedrückt wird; eine separate Ankerfeder erübrigt sich somit.The force of the movable, biased in the direction of the coil contact spring 19 is translated via the transmission member 20 and the pivot point 22 and acts on the armature 7 that this is pressed with its shorter leg 8 into the armature bearing in the yoke; a separate anchor spring is therefore unnecessary.

Dabei ist der kürzere Schenkel 8 mit seitlichen Vorsprüngen, wie sie aus der Fig. 3 zu ersehen sind, im Gehäuse 13 gelagert.The shorter leg 8 with lateral projections, as can be seen from FIG. 3, is mounted in the housing 13.

Bei dem Relais nach der Fig. 2 handelt es sich um ein Relais mit einem Arbeitskontakt, wobei die Anpressung des Ankers 7 an das Joch 1 durch die bewegliche Kontaktfeder 19 sichergestellt ist, die den Anker 7 gegen dessen abgefallene Ruhestellung vorspannt. Dabei wirkt der längere Schenkel 9 des Ankers 7 aufgrund des Vorsprunges 22 als zweiarmiger Habel, dessen einer Arm über das Übertragungsglied 22 von der beweglichen Kontaktfeder 19 beaufschlagt ist.2 is a relay with a normally open contact, the contact of the armature 7 against the yoke 1 being ensured by the movable contact spring 19, which prestresses the armature 7 against its fallen rest position. The longer leg 9 of the armature 7 acts due to the projection 22 as a two-armed fork, one arm of which is acted upon by the movable contact spring 19 via the transmission member 22.

Die Fig. 4 zeigt eine weitere Variante der Lagerung des Ankers 7 an dem Joch 1. Dabei ist in dem an der Außenseite der Spule verlaufenden Schenkel 4 des Joches 1 eine Vertiefung 23 nahe dem freien Ende dieses Schenkels 4 angeordnet, in die der kürzere Schenkel 8 des Ankers eingreift, wobei die Stirnseite des kürzeren Schenkels 8 bombiert ist.FIG. 4 shows a further variant of the mounting of the armature 7 on the yoke 1. In the leg 4 of the yoke 1 running on the outside of the coil, a depression 23 is arranged near the free end of this leg 4, into which the shorter leg 8 of the anchor engages, the end face of the shorter leg 8 is convex.
