Abstract

A magnet system for rapid disconnection is intended to be designed such that the long-term stability and operational reliability are improved with respect to known magnet systems. Since the problems of magnet systems are predominantly mechanical, the main feature of the improvement applies to the moving parts of the system. Essentially, the solution consists of designing the armature retention (7) of a magnet system as a leaf spring (71) with a box- shaped extension (72) which can be plugged on to the free pole piece (3), the leaf spring being bent and connected to the end of the hinged armature (4) projecting beyond the free pole piece, and by the tension spring (8) being suspended with its eye (81) in a hole (41) of the hinged armature, in the immediate vicinity of the connecting point (73) of the leaf spring and the hinged armature, and by the free end of the tension spring being held by a lengthened part (51) of the coil body (5), which part is firmly connected to the base plate (13) by means of pin-shaped projections (52). The area of use relates to circuits in which rapid disconnection is required. These are primarily apparatuses such as multiple instruments which must be protected against excess currents and voltages. They also include circuit breakers which are intended to protect downstream apparatuses against excess currents and voltages. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Magnetsystem für Schnellab­schaltung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a magnet system for quick shutdown according to the preamble of claim 1.

Ein derartiges Magnetsystem ist bereits bekannt (DE-PS 20 29 607). Das in einem Kunststoffgehäuse für Relais untergebrachte Magnet­system besitzt einen Klappanker, der eine Ankerhalterung in Form einer Blattfeder verwendet. Diese Blattfeder ist am Spulenkörper des Magnetsystems befestigt, was mit einer verhältnismäßig aus­gedehnten Aufhängung verbunden ist. Eine schiebende Ankerbewegung in Längsrichtung ist die Folge und es kommt zu einem starken Ab­rieb an der hinteren Schneidkante des betreffenden Polstücks. Da der auf dem anderen Polstück aufgeschobene Spulenkörper ein ge­wisses Spiel hat, lassen sich zudem die Maßverhältnisse nicht einwandfrei fixieren. Die für das Zusammenspiel mit der Blattfe­der wichtige Zugfeder, die bei der Klappankerbewegung eine große Rolle spielt, ist wegen ihrer Befestigung mit einer senkrecht zur Achse der Feder angebrachten Öseneinrichtung der Bodenplatte ver­hältnismäßig schwierig zu montieren.Such a magnet system is already known (DE-PS 20 29 607). The magnet system, housed in a plastic housing for relays, has a hinged armature that uses an armature bracket in the form of a leaf spring. This leaf spring is attached to the coil body of the magnet system, which is connected with a relatively extensive suspension. A pushing armature movement in the longitudinal direction is the result and there is a strong abrasion on the rear cutting edge of the relevant pole piece. Since the bobbin pushed onto the other pole piece has a certain amount of play, the dimensions cannot be fixed properly. The tension spring, which is important for the interaction with the leaf spring and plays a large role in the folding anchor movement, is relatively difficult to mount because of its attachment with an eyelet device of the base plate which is mounted perpendicular to the axis of the spring.

Es ähnliches Magnetsystem ist ferner aus der DE-PS 20 00 138 be­kannt. Auch hier ist die Ankerhalterung als Blattfeder ausgeführt, die einerseits auf einem Polschuh befestigt ist und andererseits mit einem Klappanker verbunden ist. Eine Schraubfeder sorgt durch Kippen des Klappankers für die Auftrennung des magnetischen Krei­ses. Das Zusammenwirken des Klappankers mit der Blattfeder und der Schraubenfeder ist aus konstruktiven Gründen jedoch verhält­nismäßig kompliziert und verlangt eine aufwendige Justage.Similar magnet system is also known from DE-PS 20 00 138. Here, too, the anchor bracket is designed as a leaf spring, which is attached to a pole piece on the one hand and is connected to a folding anchor on the other. A helical spring separates the magnetic circuit by tilting the hinged anchor. The interaction of the hinged anchor with the leaf spring and However, the coil spring is relatively complicated for constructional reasons and requires a complex adjustment.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Magnetsystem der zuvor geschilderten Art mit dem Ziel weiterzuentwickeln, die Langzeitstabilität und die Funktionssicherheit gegenüber den bekannten Magnetsystemen zu verbessern. Da die Probleme beim Mag­netsystem vorwiegend mechanischer Art sind, gilt das Hauptaugen­merk einer Verbesserung der beweglichen Teile des Systems, wie Klappanker, Ankerhalterung und Zugfeder.The invention is therefore based on the object of further developing a magnet system of the type described above with the aim of improving the long-term stability and the functional reliability compared to the known magnet systems. Since the problems with the magnet system are predominantly mechanical, the main focus is on improving the moving parts of the system, such as hinged anchors, anchor brackets and tension springs.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebene Kombination von konstruktiven Merkmalen gelöst.This object is achieved according to the invention by the combination of design features specified in the characterizing part of claim 1.

Die mit der Erfindung erzielten Vorteile bestehen in einer Verbes­serung der mechanischen Lebensdauer und einer Erhöhung des Auto­matisierungsgrades. Das einfache Aufstecken der Blattfeder auf eines der Polstücke und die stabilen Maßverhältnisse zwischen dem Polstück mit dem Spulenkörper und dem Anker und das Ein­stecken des freien Endes der Zugfeder zwischen dem verlängerten Teil des Spulenkörpers und der Bodenplatte tragen wesentlich da­zu bei, die gesteckten Ziele zu erreichen.The advantages achieved by the invention are an improvement in the mechanical life and an increase in the degree of automation. The simple plugging of the leaf spring onto one of the pole pieces and the stable dimensional relationships between the pole piece with the coil body and the armature and the insertion of the free end of the tension spring between the extended part of the coil body and the base plate make a significant contribution to achieving the goals set.

Vorteilhafte Weiter- und Ausbildungen des Gegenstandes nach An­spruch 1 sind in den Unteransprüchen angegeben.Advantageous further developments and developments of the subject matter according to claim 1 are specified in the subclaims.

So ist es von Vorteil, daß der theoretische Biegepunkt der Blatt­feder über der Schneidkante des freien Polstücks liegt (Anspruch 3). Die Blattfeder hat nicht nur die Aufgabe, den Anker sicher zu führen, damit er immer auf die gleiche Stelle des Gegenpol­stücks trifft. Durch ihre Formgebung erfüllt die Blattfeder auch die Aufgabe, die Kraftkomponente, die beim Abkippen des Ankers über die hintere Schneidkante durch die Zugfeder entsteht, so zu kompensieren, daß mindestens eine Verringerung der Belastung dieser Kante entsteht. Dies kann durch entsprechende Wahl der Gegenkraftkomponente, die von der Blattfeder erzeugt wird, so­gar soweit gehen, daß der Anker während seiner Kippbewegung von dieser Schneidkante gänzlich abhebt, was bewirkt, daß wäh­rend der Lebensdauer des Magnetsystems diese Kante überhaupt keinen Verschleiß aufweist.So it is advantageous that the theoretical bending point of the leaf spring is above the cutting edge of the free pole piece (claim 3). The leaf spring not only has the task of guiding the armature safely so that it always hits the same point on the opposite pole piece. Due to its shape, the leaf spring also fulfills the task of compensating for the force component, which is generated by the tension spring when the armature tilts over the rear cutting edge, in such a way that there is at least a reduction in the load on this edge. This can be done by choosing the appropriate one Counterforce component, which is generated by the leaf spring, even go so far that the armature lifts completely from this cutting edge during its tilting movement, which means that this edge has no wear at all during the life of the magnet system.

Da der theoretische Biegepunkt für die Wirkungsweise des Klapp­ankers von großer Bedeutung ist, ist es von Vorteil, wenn man diesen Biegepunkt durch die Wahl von Ausnehmungen in den ver­bleibenden Seitenstreifen der Blattfeder festlegen kann (An­spruch 4).Since the theoretical bending point is of great importance for the mode of operation of the hinged anchor, it is advantageous if this bending point can be determined by the selection of recesses in the remaining side strips of the leaf spring (claim 4).

Zum Aufstecken der Ankerhalterung dient eine kastenförmige Ver­längerung, die vorteilhafterweise derart vorgebogen ist, daß sie auf dem freien Polstück federnd und selbstklemmend sitzt (Anspruch 5).A box-shaped extension is used to attach the anchor bracket, which is advantageously pre-bent in such a way that it sits resiliently and self-locking on the free pole piece (claim 5).

Zusätzlich zu dieser Maßnahme kann man die kastenförmige Ver­längerung mittels doppelseitiger Punktschweißung am freien Polstück befestigen, womit die Ankerhalterung vorteilhafterweise exakt fixiert ist (Anspruch 7).In addition to this measure, the box-shaped extension can be attached to the free pole piece by means of double-sided spot welding, whereby the anchor bracket is advantageously precisely fixed (claim 7).

Das Einschneiden an allen Ecken der kastenförmigen Verlängerung und das anschließende Aufbiegen der eingeschnittenen Seiten­teile erleichtert das Aufstecken der Ankerhalterung (Anspruch 8).The incision at all corners of the box-shaped extension and the subsequent bending of the incised side parts facilitates the attachment of the anchor bracket (claim 8).

Bei der Zugfeder genügt es, wenn man das freie Ende in das ver­längerte Teil des Spulenkörpers von unten einsteckt, wobei die Bodenplatte die Aufgabe übernimmt, das Zugfederende gegen Heraus­fallen zu halten (Anspruch 9).With the tension spring, it is sufficient if the free end is inserted into the extended part of the coil body from below, the base plate taking on the task of holding the tension spring end against falling out (claim 9).

Nach Fig. 1 und 2 besteht das Magnetsystem aus einem Joch 1, zu dem rechtwinklig hierzu zwei Polstücke 2 und 3 angeordnet sind. Auf den beiden Polstücken liegt ein Klappanker 4, der über eine Schneidkante 31 des Polstücks 3 abkippt. Hierzu ist der Klappanker über seine Auflagefläche auf dem Polstück 3 hinaus verlängert. Der Klappanker wird durch eine Ankerhalte­rung 7 gehalten, die aus einer Blattfeder 71 und einer kasten­förmigen Verlängerung 72 besteht. Die Blattfeder ist mit dem verlängerten Teil des Klappankers im Verbindungspunkt 73 ver­bunden, während das kastenförmige Teil auf dem Polstück 3 auf­gesteckt ist. Ein Spulenkörper 5 mit einer Wicklung sitzt auf dem Polstück 2. An der von den Polstücken abgewandten Seite des Klappankers befindet sich ein Auslösestift 6, der eine Kappe 12 durchdringt. Im verlängerten Teil des Klappankers be­findet sich eine Bohrung 41, in welche die Öse 81 einer Zug­feder 8 eingehängt ist. Die Blattfeder besitzt einen theore­tischen Biegepunkt 74, der über der Schneidkante 31 des Pol­stücks 3 liegt. Der Spulenkörper 5 weist ein verlängertes Teil 51 auf, das mit einer Einstecköffnung 10 für die Zugfeder 8 ausgestattet ist. Hierzu ist die Zugfeder am Ende mit zwei Windungen ausgestattet, die im Durchmesser größer als die übrigen Durchmesser sind. Die beiden größeren Windungen kommen in einer Mulde 131 der Bodenplatte 13 zu liegen. Da die zwei letzten Windungen in ihrem Durchmesser größer als die Einsteck­öffnung 10 sind, erfolgt die Halterung des Zugfederendes nach Einlegen der beiden letzten Windungen in die Mulde und durch Zusammenfügen des Spulenkörpers mit der Bodenplatte. Der Spu­lenkörper ist mit stiftförmigen Ansätzen 52 versehen, die in Bohrungen der Bodenplatte eingesteckt und anschließend ver­schweißt werden. Die Bodenplatte enthält außerdem noch eine Mulde, in welcher ein Permanentmagnet 11 eingesetzt ist.1 and 2, the magnet system consists of a yoke 1, to which two pole pieces 2 and 3 are arranged at right angles thereto. On the two pole pieces there is a hinged anchor 4 which tilts over a cutting edge 31 of the pole piece 3. For this purpose, the hinged anchor is extended beyond its contact surface on the pole piece 3. The hinged anchor is held by an anchor bracket 7, which consists of a leaf spring 71 and a box-shaped extension 72. The leaf spring is connected to the extended part of the hinged anchor in the connection point 73, while the box-shaped part is attached to the pole piece 3. A coil former 5 with a winding is seated on the pole piece 2. On the side of the hinged armature facing away from the pole pieces there is a release pin 6 which penetrates a cap 12. In the extended part of the hinged anchor there is a bore 41 into which the eyelet 81 of a tension spring 8 is suspended. The leaf spring has a theoretical bending point 74, which lies above the cutting edge 31 of the pole piece 3. The coil former 5 has an elongated part 51 which is equipped with an insertion opening 10 for the tension spring 8. For this purpose, the tension spring is equipped with two turns at the end, which are larger in diameter than the other diameters. The two larger turns come to lie in a depression 131 in the base plate 13. Since the last two turns are larger in diameter than the insertion opening 10, the tension spring end is held after inserting the last two turns into the trough and by joining the coil former to the base plate. The coil body is provided with pin-shaped projections 52, which in Holes in the base plate are inserted and then welded. The base plate also contains a trough in which a permanent magnet 11 is inserted.

Nach Fig. 3 bis 5 besteht die Ankerhalterung 7 aus einer Blatt­feder 71 und einer kastenförmigen Verlängerung 72. Mit 73 ist der Verbindungspunkt der Blattfeder mit dem Klappanker be­zeichnet. Ein theoretischer Biegepunkt 74 besteht im Bereich der Blattfeder derart, daß dieser Biegepunkt nach Aufstecken der Ankerhalterung auf dem Polstück 3 über der Schneidkante dieses Polstücks zu liegen kommt. Die Blattfeder besitzt einen Ausschnitt 75, der eine etwa rechteckige Form aufweist. Die im Bereich dieses Ausschnitts verbleibenden Seitenstreifen 76 sind so beschaffen, daß der Klappanker sich ungehindert be­wegen kann. Um eine federnde Wirkung der kastenförmigen Ver­längerung zu erreichen, sind die Seitenteile mit Biegewinkeln 77 vorgebogen, die kleiner als 90° sind. Um die Ankerhalte­rung leichter auf das Polstück 3 aufsetzen zu können, sind die unteren Ecken der Seitenteile mit einem Einschnitt 78 ver­sehen und die Seitenteile bis in Höhe der Einschnitte leicht nach außen gebogen.3 to 5, the anchor bracket 7 consists of a leaf spring 71 and a box-shaped extension 72. The connection point of the leaf spring to the hinged anchor is designated by 73. There is a theoretical bending point 74 in the area of the leaf spring in such a way that this bending point comes to rest on the pole piece 3 after the anchor holder has been plugged on, over the cutting edge of this pole piece. The leaf spring has a cutout 75 which has an approximately rectangular shape. The side strips 76 remaining in the area of this cutout are designed so that the hinged anchor can move freely. In order to achieve a resilient effect of the box-shaped extension, the side parts are pre-bent with bending angles 77 which are less than 90 °. In order to be able to place the anchor bracket on the pole piece 3 more easily, the lower corners of the side parts are provided with an incision 78 and the side parts are slightly bent outwards up to the level of the incisions.

Nach Fig. 6 besteht auch die Möglichkeit, den theoretischen Biegepunkt mit Hilfe von Ausnehmungen 79 festzulegen.6 there is also the possibility of defining the theoretical bending point with the aid of recesses 79.
