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, wobei 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 und wobei der kürzere Schenkel des Joches in das Innere der Spule eingreift.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, the armature L- is shaped and is mounted with its shorter leg on the longer, extending on the outside of the coil leg of the U-shaped, integrally formed yoke and wherein the shorter leg of the yoke engages in the interior of the coil.
Bei einem aus der EP-B1-0 070 717 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.
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. 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.In a relay known from EP-B1-0 070 717, 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.
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. 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 there are a total of three air gaps due to the two-part yoke, etc. 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.
Aus der den nächstkommenden Stand der Technik beschreibenden EP-A2-0 203 496 ist ferner ein elektromagnetisches Relais bekanntgeworden, welches eine Durchgangsöffnung in seinem Spulenkörpers aufweist, in die ein erster, kurzer Schenkel eines U-förmigen Joches und der lange Schenkel eines L-förmigen Ankers hineinreicht, der mit seinem freien Ende eine Kontaktfeder betätigt. Zwischen diesem Jochschenkel und dem Anker ist ein Arbeitsluftspalt schräg zur Spulenachse ausgebildet. Der Anker ist mit seinem kurzen Schenkel an einem an der Außenseite der Spule verlaufenden Schenkel des U-förmigen Joches gelagert.From EP-A2-0 203 496, which describes the closest prior art, an electromagnetic relay has also become known, which has a through opening in its coil former into which a first, short leg of a U-shaped yoke and the long leg of an L-shaped one Armature reaches into it, which actuates a contact spring with its free end. A working air gap is formed obliquely to the coil axis between this yoke leg and the armature. The armature is supported with its short leg on a leg of the U-shaped yoke running on the outside of the coil.
Die EP-A2-0 062 332 offenbart ein elektromagnetisches Relais mit einer Spule, einem zweiteiligen Joch und einem Anker, der in eine zentrale Öffnung des Spulenkörpers eingreift, welcher mit Vorsprüngen versehen ist, die in diese zentrale Öffnung ragen. Durch diese Vorsprünge wird der Anker locker gelagert. An der Wurzel des Ankers ist eine Nase angeformt, die auf einem Schenkel des Joches aufliegt und so einen Drehpunkt für den Anker definiert. Am anderen Ende des Ankers ist ein Betätigungskamm zum Bewegen eines Federkontaktes angeordnet, welcher zwischen zwei festen Kontakten bewegbar ist. In seinem Ruhezustand berührt der Anker mit seiner Nase den Schenkel des Joches und der Betätigungskamm drückt den Federkontakt gegen den einen festen Kontakt. Bei Anregung der Relaisspule wird der Anker um den den aus Jochschenkel und Ankernase gebildeten Drehpunkt geschwenkt. Für den letzten Teil des Schwenkvorganges hebt die Ankernase vom Jochschenkel ab, wobei der Vorsprung des Spulenkörpers als Angelpunkt für den Anker dient.EP-A2-0 062 332 discloses an electromagnetic relay with a coil, a two-part yoke and an armature which engages in a central opening of the coil body, which is provided with projections which protrude into this central opening. The anchor is loosely supported by these projections. A nose is formed on the root of the anchor, which rests on one leg of the yoke and thus defines a pivot point for the anchor. At the other end of the armature there is an actuating comb for moving a spring contact which can be moved between two fixed contacts. In its idle state, the anchor touches the leg of the yoke with its nose and the actuating comb presses the spring contact against the one fixed contact. When the relay coil is excited, the armature is pivoted about the pivot point formed from the yoke leg and armature nose. For the last part of the swiveling process, the anchor nose lifts off the yoke leg, the projection of the coil former serving as the pivot point for the anchor.
Die EP-A2-0 310 091 zeigt ein elektromagetnisches Relais mit einem Spulenkörper, welcher eine Stufe in seinem mittleren Bereich aufweist. In einer Öffnung dieses Spulenkörpers greifen ein L-förmiger Anker und der Schenkel eines Joches ein und bilden dabei einen Spalt aus. Eine gabelartige Ankerfeder hält den Anker in seiner abgefallenen Position.EP-A2-0 310 091 shows an electromagnetic relay with a coil body, which has a step in its central region. An L-shaped armature and the leg of a yoke engage in an opening of this coil former and thereby form a gap. A fork-like anchor spring holds the anchor in its dropped position.
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 besteht darin, 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 is that the moving parts have little play.
Bei einem Relais der eingangs genannten Art besteht die Erfindung darin, 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 relay of the type mentioned, the invention is that the longer leg of the armature is formed as a double-armed lever by support on the inner wall of the coil or 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 einer Weiterbildung der Erfindung kann vorgesehen sein, daß der Anker mit der von der Stirnseite der Spule abgekehrten Kante am Joch gelagert ist.According to a development 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 einer Weiterbildung 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 development 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 supported 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 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 einer anderen Weiterbildung 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 another development 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 unavoidable air gap between the yoke and armature results in only a low magnetic resistance and larger scattering losses are avoided, so that with a correspondingly low flooding, it can be found to be sufficient.
In Weiterbildung der Erfindung kann vorgesehen 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.In a further development of the invention it can be provided that the arm 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.
