Description

Die Erfindung betrifft ein elektromagnetisches Relais mit einem eine Kappe umfassenden Gehäuse, einem in dem Gehäuse angeordneten Magnetsystem mit einer Spule und einem entlang der Spulenaußenseite angeordneten, um eine Schwenkachse im Bereich der Spulenmitte schwenkbar gelagerten Anker und mit einem mit dem Anker verbundenen, durch ein Betätigungsfenster der Kappe von außen zugänglichem Betätigungsorgan.The invention relates to an electromagnetic relay with a a housing comprising a cap, one arranged in the housing Magnetic system with a coil and one along the Coil outside arranged around a pivot axis in the area the coil center pivoted armature and with a connected to the anchor through an operating window the cap of the actuator accessible from the outside.

Ein derartiges Relais ist beispielsweise aus der DE-A1-36 24 783 bekannt. Dort ist ein polarisiertes Relaissystem mit einem sogenannten H-Anker gezeigt, bei dem ein Betätigungshebel in Verlängerung des einen Ankerschenkels angeordnet ist und mit einem seitlichen Versatz durch eine Öffnung des Gehäuses nach außen tritt. Das dortige Relais besitzt allerdings eine sehr große Bauhöhe, da die Spulenachse und der Anker senkrecht zur Bodenseite bzw. Einbauebene des Relais stehen, so daß der Betätigungshebel an der Gehäuseoberseite zugänglich ist. Bei einer Drehung des Systems um 90° zur Erzielung einer flachen Bauform würde jedoch der Betätigungshebel aus einer Seitenwand austreten, was die Zugänglichkeit auf einer Leiterplatte erschweren würde. Zudem bewirkt der in einer einseitigen Verlängerung des Ankers ausgebildete Betätigungshebel eine unsymmetrische und je nach Schaltrichtung ungleiche Krafteinwirkung. Insbesondere ergibt sich in der einen Schaltrichtung eine Kraftkomponente, die den Anker von der Spule und den Polschuhen weg nach außen zu ziehen bestrebt ist. Bei dem dort gezeigten zapfengelagerten H-Anker hat dies keine besonderen Auswirkungen; bei einem nur einseitig auf Polblechen und eventuell einem Dauermagneten aufliegenden und lediglich durch Magnetkraft oder durch eine Feder in der Lagerung gehaltenen Wippanker könnte dies jedoch zu einem unerwünschten Abheben des Ankers oder gegebenenfalls zu einer unerwünschten Deformation einer Lagerfeder führen.Such a relay is for example from DE-A1-36 24 783 known. There is a polarized relay system shown with a so-called H-anchor, in which an operating lever arranged in the extension of an anchor leg and with a lateral offset through an opening of the housing comes out. However, the relay there has a very large height because the coil axis and the Anchor perpendicular to the bottom side or installation level of the relay stand so that the operating lever on the top of the housing is accessible. When the system is rotated 90 ° to achieve this a flat design, however, would be the actuating lever emerge from a side wall, which is accessibility would complicate on a circuit board. In addition, the in a one-sided extension of the armature trained operating lever an asymmetrical and depending on the switching direction unequal force. In particular, in the a switching direction a force component that the armature of tends to pull the coil and pole pieces outward is. In the case of the H-bolt with a journal bearing there this has no special effects; only one-sided on pole plates and possibly a permanent magnet and only by magnetic force or by a spring However, this could result in rocker anchors held in storage an undesirable lifting of the anchor or, if necessary lead to an undesirable deformation of a bearing spring.

Ziel der vorliegenden Erfindung ist es, ein Relais der eingangs genannten Art mit einem Betätigungsorgan derart zu gestalten, daß ungünstige Krafteinwirkungen auf das Ankerlager, die zu einem Abheben des Ankers führen könnten, vermieden werden. Insbesondere soll es dabei möglich sein, bei einer flachen Bauform des Relais mit liegendem Magnetsystem die Handbetätigung von der Gehäuseoberseite her durchzuführen.The aim of the present invention is to provide a relay of the input to design the type mentioned with an actuator in such a way that unfavorable force effects on the anchor bearing, avoided, which could lead to lifting of the anchor become. In particular, it should be possible for one flat design of the relay with horizontal magnet system Perform manual operation from the top of the housing.

Erfindungsgemäß wird dieses Ziel dadurch erreicht, daß das Betätigungsorgan mindestens einen in der Nähe der Schwenkachse des Ankers von dessen Oberfläche annähernd senkrecht nach außen ragenden Schaltnocken besitzt.According to the invention this goal is achieved in that the Actuator at least one near the pivot axis of the anchor from its surface approximately perpendicular has outwardly projecting switch cams.

In einer vorteilhaften Ausführungsform besitzt das Betätigungsorgan einen einzigen Schaltnocken in Form eines Kipphebels, der sich in Radialrichtung zur Schwenkachse des Ankers nach außen erstreckt. Dabei wird also der Anker genau über seiner Mitte und über seiner Schwenkachse durch einen Kipphebel betätigt. Grundsätzlich kann aber das Betätigungsorgan auch als Wippe ausgebildet sein, wobei die Betätigung durch Druck auf den jeweiligen Flügel der Wippe und damit auf den jeweiligen Ankerflügel erfolgt. Diese Wippe kann ebenso wie der Kipphebel als einstückiges Betätigungsorgan beispielsweise aus Kunststoff gefertigt und auf dem Anker durch Steckzapfen oder dergleichen befestigt sein. Es kann aber auch der Anker selbst die Wippe bilden, wobei dann zwei getrennte Schaltnocken beiderseits im Abstand von der Drehachse auf den Anker aufgesetzt sind. Läßt man einen dieser Schaltnocken weg, so ergibt sich ein einseitiges Betätigungsorgan für den Fall, daß es sich um ein monostabiles Magnetsystem handelt, bei dem der Anker durch einen Magneten oder durch Federkraft automatisch immer in die gleiche Ruhestellung zurückgesetzt wird.In an advantageous embodiment, the actuator has a single switch cam in the form of a rocker arm, which is in the radial direction to the pivot axis of the armature extends outwards. So the anchor is exactly over its center and above its pivot axis by a rocker arm operated. Basically, however, the actuator also be designed as a rocker, the actuation by Pressure on the respective wing of the seesaw and thus on the respective anchor wing. This seesaw can as well the rocker arm as a one-piece actuator, for example made of plastic and on the anchor by plug or the like. But it can also Anchors themselves form the seesaw, then two separate ones Switch cams on both sides at a distance from the axis of rotation Anchors are attached. If you leave one of these switch cams away, so there is a one-sided actuator for the If it is a monostable magnet system, where the armature by a magnet or by spring force automatically reset to the same rest position becomes.

Um den Schaltzustand auch nach außen kenntlich zu machen, ist in einer vorteilhaften Ausgestaltung vorgesehen, daß das Betätigungsorgan jeweils in Richtung der Schaltbewegung neben dem jeweiligen Schaltnocken Markierungen trägt, wobei je nach Schaltstellung unterschiedliche Markierungen durch ein Sichtfenster der Kappe sichtbar sind. Dabei kann dieses Sichtfenster jeweils ein Bereich des Betätigungsfensters sein oder als vom Betätigungsfenster getrenntes zusätzliches Fenster in der Kappe ausgespart sein.In order to make the switching status visible to the outside, is provided in an advantageous embodiment that the actuator each in the direction of the switching movement the respective switch cam carries markings, depending on Switch position different markings through a window the cap are visible. This window can each be an area of the operating window or as an additional window separated from the operating window in be spared the cap.

Die Erfindung wird nachfolgend an Ausführungsbeispielen anhand der Zeichnung näher erläutert. Es zeigt

  • Figur 1 ein erfindungsgemäß gestaltetes Relais in Seitenansicht mit aufgeschnittener Kappe mit einem Kipphebel als Schaltnocken,
  • Figur 2 das Relais von Figur 1 in perspektivischer Darstellung, jedoch mit etwas abgewandeltem Betätigungsorgan in Form einer Wippe mit zwei Schaltnocken,
  • Figur 3 eine Ausführungsform wie in Figur 2, jedoch als monostabiles System mit nur einem Schaltnocken,
  • Figur 4 und 5 zwei Seitenansichten des Relais von Figur 1 mit Markierungen zur Kennzeichnung der Schaltstellung.
    • The invention is explained in more detail below using exemplary embodiments with reference to the drawing. It shows
  • FIG. 1 is a side view of a relay designed according to the invention with a cut cap with a rocker arm as a switching cam,
  • 2 shows the relay of FIG. 1 in a perspective view, but with a somewhat modified actuating member in the form of a rocker with two switching cams,
  • 3 shows an embodiment as in FIG. 2, but as a monostable system with only one switching cam,
  • Figures 4 and 5 two side views of the relay of Figure 1 with markings to indicate the switching position.

    • Das in Figur 1 gezeigte Relais besitzt ein an sich bekanntes Magnetsystem mit einer in einem Grundkörper 1 verdeckt angeordneten Spule 2 mit einer zur Bodenseite parallelen Achse, mit einem innerhalb der Spule angeordneten Kern, dessen Enden mit zwei Jochen 3 und 4 verbunden sind. Zwischen den Enden der beiden Joche 3 und 4 ist ein plattenförmiger Dauermagnet 5 parallel zur Spulenachse angeordnet. Der Dauermagnet ist dreipolig aufmagnetisiert, wobei die beiden äußeren Pole mit den Jochen 3 und 4 gekoppelt sind, während auf dem Mittelpol ein Wippanker 6, dessen zwei Flügel zueinander einen stumpfen Winkel bilden, abrollbar gelagert ist. Als Halterung für den Anker dient eine Ankerfeder 7. Der Anker 6 bildet mit den beiden Jochen 3 und 4 jeweils einen Luftspalt, so daß er jeweils im Ruhezustand nicht in der dargestellten Mittelposition steht, sondern wahlweise an einem der Joche 3 oder 4 festgehalten wird. Durch einen entsprechenden Stromimpuls in der Spule wird der Anker dieses bistabilen Systems umgeschaltet. Es ist aber auch möglich, durch zusätzliche Federkraft oder durch unsymmetrischen Abgleich des Dauermagneten 5 ein monostabiles Schaltverhalten zu erzielen. Durch das Ankerende 6a wird über einen Schieber 8 in ebenfalls bekannter Weise ein Kontaktsystem 9 geschaltet; dies soll hier nicht im einzelnen ausgeführt werden. Im übrigen ist das Relaissystem in einem durch eine Grundplatte 10 und eine Kappe 11 gebildeten Gehäuse untergebracht. The relay shown in Figure 1 has a known per se Magnet system with a hidden in a base body 1 Coil 2 with an axis parallel to the bottom side, with a core arranged inside the coil, the ends of which are connected with two yokes 3 and 4. Between the ends the two yokes 3 and 4 is a plate-shaped permanent magnet 5 arranged parallel to the coil axis. The permanent magnet is magnetized three-pole, the two outer poles with the yokes 3 and 4 are coupled, while on the center pole a rocker armature 6, the two wings of which are blunt to each other Form angle, is mounted rollable. As a holder for the An anchor serves an anchor spring 7. The anchor 6 forms with the two yokes 3 and 4 each have an air gap, so that it each not in the middle position shown in the idle state stands, but optionally on one of the yokes 3 or 4 is held. By a corresponding current pulse in the armature of this bistable system is switched over the coil. But it is also possible with additional spring force or by asymmetrical adjustment of the permanent magnet 5 to achieve monostable switching behavior. Through the anchor end 6a is also via a slide 8 in a known manner a contact system 9 switched; this is not meant to be detailed here be carried out. Otherwise the relay system is in one formed by a base plate 10 and a cap 11 Housing housed.

    Zur zusätzlichen manuellen Betätigung des Relais ist der Anker 6 mit einem Betätigungsorgan 12 versehen, das mittig auf dem Anker über dessen Lagerbereich sitzt und einen radial zur Lagerachse nach außen ragenden Schaltnocken in Form eines Kipphebels 13 aufweist. Das Betätigungsorgan 12 ist mit dem Anker fest verbunden, beispielsweise durch Befestigungszapfen 14, die in Ausnehmungen 15 des Ankers eingesteckt sind. Es wäre aber auch denkbar, das Betätigungsorgan durch Spritzgießen oder auf eine ähnliche Weise mit dem Anker zu verbinden. Denkbar wäre auch, ein Betätigungsorgan einstückig mit dem Anker durch entsprechende Formgebung auszubilden.The armature is for additional manual actuation of the relay 6 provided with an actuator 12 which is centered on the anchor sits over the bearing area and a radial to Bearing shaft protruding outwards in the form of a Has rocker arm 13. The actuator 12 is with the Anchors firmly connected, for example by fastening pins 14, which are inserted into recesses 15 of the armature. It but would also be conceivable, the actuator by injection molding or to connect to the anchor in a similar manner. It would also be conceivable for an actuator to be integral with the Form anchors by appropriate shaping.

    Um eine Betätigung von außen zu ermöglichen, ragt der Kipphebel 13 durch ein Betätigungsfenster 16 der Gehäusekappe 11. Dieses Betätigungsfenster ist in seiner Ausdehnung so bemessen, daß der Kipphebel 13 in beiden Richtungen in Ankerlängsrichtung soweit bewegt werden kann, bis der Anker seine jeweilige Endstellung erreicht hat. An der Stellung des Kipphebels in dem Betätigungsfenster 16 ist auch der jeweilige Schaltzustand des Relais erkennbar. Um einen verhältnismäßig langen Hebelarm für den Kipphebel 13 zu erreichen, erstreckt sich in dem Beispiel gemäß Figur 1 das Betätigungsorgan mit einem Ansatz 12a in eine Ausbuchtung lla der Kappe 11. Dadurch wird auch der Schaltweg des Kipphebels 13 länger, und die Schaltstellungen unterscheiden sich deutlicher voneinander. Wenn dies nicht erforderlich ist bzw. wenn die zulässige Bauhöhe des Relais dies nicht zuläßt, kann auch mit einem kürzeren Hebelarm für den Kipphebel 13 gearbeitet werden. The rocker arm protrudes to enable external actuation 13 through an actuation window 16 of the housing cap 11. This actuation window is dimensioned in such a way that that the rocker arm 13 in both directions in the longitudinal direction of the armature as far as the anchor can move its respective Has reached the end position. At the position of the rocker arm in the operating window 16 is also the respective one Switching status of the relay recognizable. To be proportionate to reach long lever arm for the rocker arm 13 extends the actuator in the example of FIG an approach 12a in a bulge 11a of the cap 11. This the switching path of the rocker arm 13 is longer, and the switch positions differ more clearly from each other. If this is not necessary or if the permissible Height of the relay does not allow this can also be done with a shorter lever arm for the rocker arm 13 can be worked.

    Figur 2 zeigt eine etwas abgewandelte Ausführungsform, welche insbesondere auf jegliche Vergrößerung der Bauhöhe verzichtet. Das in Figur 2 perspektivisch gezeigte Relaissystem ist grundsätzlich genauso aufgebaut wie in Figur 1. Lediglich das Betätigungsorgan ist abgewandelt. Dieses besteht nunmehr aus zwei getrennten Schaltnocken 17 und 18, welche getrennt auf dem Anker, beispielsweise durch Aufstecken, befestigt sind. Jeder der Schaltnocken 17 und 18 ragt in ein eigenes Betätigungsfenster 19 bzw. 20, ohne über die Oberfläche der Kappe 11 überzustehen. Die beiden Schaltnocken 17 und 18 könnten aber auch Teile eines gemeinsamen Betätigungsorgans sein, das wie in Figur 1 auf dem Anker befestigt ist.Figure 2 shows a slightly modified embodiment, which in particular, waived any increase in the overall height. The relay system shown in perspective in FIG. 2 is basically constructed exactly as in Figure 1. Only that Actuator has been modified. This now consists of two separate switching cams 17 and 18, which on separately the anchor, for example by attaching, are attached. Each of the switching cams 17 and 18 protrudes into its own actuation window 19 or 20 without over the surface of the cap 11 survive. The two switching cams 17 and 18 could but also be part of a common actuator that is attached to the anchor as in Figure 1.

    Der Hebelarm wird in diesem Fall durch die Entfernung der beiden Schaltnocken 17 und 18 von der Ankerdrehachse gebildet; der Anker bildet also selbst die Schaltwippe. Die Betätigung erfolgt in diesem Fall nicht durch eine Verschiebung eines Hebels in Ankerlängsrichtung, sondern durch einen Druck auf einen der Schaltnocken 17 bzw. 18 von außen in Richtung etwa senkrecht zur Ankeroberfläche. Um die Schaltnocken 17 und 18 besser erreichen zu können, ist der Bereich 21 zwischen den beiden Betätigungsfenstern 19 und 20 nach innen zurückgesetzt. Der Schaltzustand des Relais ist in diesem Fall an der jeweililgen Höhenposition der beiden Schaltnocken 17 und 18 zu erkennen.In this case, the lever arm is removed by removing the two switching cams 17 and 18 formed by the armature axis of rotation; the anchor itself forms the rocker switch. The actuation in this case is not carried out by a shift a lever in the longitudinal direction of the armature, but by pressure on one of the switching cams 17 and 18 from the outside in the direction approximately perpendicular to the anchor surface. To the switching cams 17th and 18 to reach better, the area 21 is between the two operating windows 19 and 20 reset inwards. The switching state of the relay is in this case at the respective height position of the two switching cams 17th and 18 to recognize.

    Figur 3 zeigt den gleichen Aufbau wie Figur 2, wobei lediglich der eine Schaltnocken 17 und das entsprechende Betätigungsfenster 19 weggelassen sind, so daß nur ein einziger, im Abstand von der Drehachse des Ankers 6 angreifender Schaltnocken 18 vorhanden ist. Für diese Ausführungsform ist jedoch vorauszusetzen, daß das Magnetsystem monostabil ist, so daß aufgrund von Magnet- oder Federkräften der Anker im Ruhezustand an das Joch 3 angezogen wird. Eine Handbetätigung kann in diesem Fall also nur durch den Schaltnocken 18 in Richtung auf das Joch 4 vorgenommen werden.Figure 3 shows the same structure as Figure 2, only the one switching cam 17 and the corresponding actuation window 19 are omitted, so that only one, in Distance from the axis of rotation of the armature 6 engaging switch cams 18 is present. However, for this embodiment assuming that the magnet system is monostable so that due to magnetic or spring forces, the armature at rest is attracted to the yoke 3. A manual operation can in this case only by the switching cam 18 in the direction be made on the yoke 4.

    In den Figuren 4 und 5 ist bei einem Relaisaufbau gemäß Figur 1, wobei die Kappe 11 geschlossen und nur im Bereich des Betätigungsorgans aufgeschnitten gezeigt ist, die Sichtbarmachung einer Markierung dargestellt. Auf dem Ansatz 12a des Betätigungsorgans 12 sind beiderseits des Kipphebels 13 jeweils Markierungsfelder mit dunklen Bereichen 22 und hellen Bereichen 23 vorgesehen. In der Zeichnung sind diese Markierungsfelder zur Hervorhebung vergrößert gezeichnet. In Wirklichkeit handelt es sich nur um farbige Oberflächenschichten auf dem Betätigungsorgan 12, die in der Seitenansicht kaum sichtbar wären. In der Praxis könnte beispielsweise der dunkle Bereich 22 jeweils rot und der helle Bereich 23 jeweils weiß oder auch schwarz gehalten sein. Es kommt lediglich darauf an, daß zwischen den beiden Bereichen ein Kontrast in der Farbe bzw. in der Helligkeit an der Relaisoberseite sichtbar wird. Über den Markierungsfeldern sind in der Gehäusekappe 11 jeweils Sichtfenster 24 und 25 vorgesehen. Diese Sichtfenster 24 und 25 sind als Schlitze so schmal gehalten, daß je nach Schaltstellung jeweils nur die Markierungsbereiche 22 oder die andersfarbigen Markierungsbereiche 23 sichtbar sind.FIGS. 4 and 5 show a relay structure according to FIG 1, the cap 11 closed and only in the area of the actuator shown cut open, the visualization represented by a marker. On the approach 12a of the Actuator 12 are on both sides of the rocker arm 13 each Markers with dark areas 22 and light ones Areas 23 are provided. These are check boxes in the drawing enlarged to emphasize. In reality it is only a question of colored surface layers on the actuator 12, the side view hardly would be visible. In practice, for example dark area 22 each red and light area 23 each be white or black. It just comes suggest that there is a contrast between the two areas in color or brightness on the top of the relay becomes visible. Above the check boxes are in the Housing cap 11 each provided viewing window 24 and 25. These viewing windows 24 and 25 are kept as narrow as slots, that depending on the switch position only the marking areas 22 or the different colored marking areas 23 are visible.

    Anstelle der zusätzlichen Sichtfenster 24 und 25 könnte auch das Betätigungsfenster 16 zur Lageerkennung genutzt werden. So würde je nach Schaltstellung der Fensterbereich 16a auf der einen Seite des Kipphebels 13 oder der Fensterbereich 16b auf der anderen Seite des Kipphebels 13 die Funktion eines Sichtfensters erhalten, wenn unterhalb des Betätigungsfensters 16 das Betätigungsorgan 12 farbige Markierungen, und zwar zu beiden Seiten des Kipphebels 13 in unterschiedlicher Farbe, erhalten würde.Instead of the additional viewing window 24 and 25 could also the operating window 16 can be used for position detection. Depending on the switching position, the window area 16a would open one side of the rocker arm 13 or the window area 16b on the other side of the rocker arm 13 the function of a Get viewing window if below the actuation window 16 the actuator 12 colored markings, and on both sides of the rocker arm 13 in different Color, would get.

    Durch die in den Figuren 4 und 5 gezeigte trichterförmige Erweiterung der Sichtfenster 24 und 25 nach außen werden der Lichteinfall und die Einsehbarkeit der Farbmarkierungen durch die Sichtfenster verbessert, die ansonsten wegen der geringen Distanz zwischen den beiden Schaltstellungen sehr schmal gehalten werden müssen.Through the funnel-shaped expansion shown in Figures 4 and 5 the viewing window 24 and 25 to the outside Incidence of light and the visibility of the color markings the viewing window improved, otherwise because of the small Distance between the two switch positions kept very narrow Need to become.
