Description

Die Erfindung betrifft einen mindestens 3-poligen Überstromschutzschalter.The invention relates to an at least 3-pole overcurrent circuit breaker.

1-polige Überstromschutzschalter sind allgemein geläufig (DE 27 21 162 C2). Es ist weiterhin bekannt, einen 2-poligen Überstromschutzschalter durch die Aneinanderreihung zweier 1-poliger Überstromschutzschalter dadurch herzustellen, dass die Funktionsteile der beiden Einzelschalter beiderseits einer quer zur Reihenrichtung verlaufenden Trennwand in einem gemeinsamen Gehäuse positioniert sind, wobei weiter die Bewegungsteile dieser beiden Einzelschalter zu jeweils gemeinsamer Überstromauslösung mechanisch über Steckachsen miteinander verbunden sind (DE 27 21 162 C2; Fig. 4-8).1-pole overcurrent circuit breakers are common (DE 27 21 162 C2). It is also known to produce a 2-pole overcurrent circuit breaker by the juxtaposition of two 1-pole overcurrent protection switch that the functional parts of the two individual switches are positioned on both sides of a transverse to the row direction partition wall in a common housing, wherein further the moving parts of these two individual switches to each common overcurrent tripping mechanically interconnected via thru axles (DE 27 21 162 C2, Fig. 4-8).

Zunehmend werden vom Markt Anwendungen verlangt, bei denen 3 Phasen oder 3 Phasen und der Neutralleiter geschaltet oder geschützt werden müssen. Solche Anwendungen können beispielsweise Pumpen, Hochdruckreiniger oder Motorschutz allgemein sein.Increasingly, the market demands applications in which 3 phases or 3 phases and the neutral conductor must be switched or protected. Such applications may be, for example, pumps, high-pressure cleaners or motor protection in general.

Bei einem aus der EP 0 616 347 A1 bekannten mehrpoligen Schutzschalter sind eine der Polzahl des Schutzschalters entsprechende Anzahl von Gehäuseschalen gleichsinnig aneinandergesetzt, deren jede einen 1-poligen Schutzschatter aufnimmt. Die Bewegungs- und Funktionsteile der einzelnen 1-poligen Schutzschalter sind zur gemeinsamen Auslösung aller Pole durch eine die Gehäuseschalen in Reihenrichtung durchsetzende Kopplungsstange mechanisch gekoppelt.In a multi-pole circuit breaker known from EP 0 616 347 A1, a number of housing shells corresponding to the number of poles of the circuit breaker are placed in the same direction in the same direction, each of which receives a 1-pole protective contactor. The movement and functional parts of the individual 1-pole circuit breaker are mechanically coupled for common triggering of all poles by a coupling rod passing through the housing shells in the row direction.

Femer ist aus der EP 0 538 149 A1 ein mehrpoliger Niederspannungs-Leistungsschalter bekannt, der eine Anzahl von in einem gemeinsamen Gehäuse angeordneten Einzelpolblöcken aufweist, deren jeder einen von einem Kasten bzw. einer Kammer umgebenen 1-poligen Einzelschalter enthält. Um für den bekannten mehrpoligen Leistungsschalter eine gleichmäßige, insbesondere einer entsprechenden Reihung von separaten 1-poligen Schaltern entsprechende Anschlussteilung zu schaffen, ist zwischen je zwei Einzelpolblöcke ein Trennsteg als Abstandshalter eingesetzt, dessen Breite der doppelten Stärke der Gehäusewand entspricht.Furthermore, from EP 0 538 149 A1 a multi-pole low-voltage circuit breaker is known which has a number of arranged in a common housing Einzelpolblöcken, each one of a box or a Chamber containing 1-pole single switch contains. In order to provide for the known multi-pole circuit breaker a uniform, in particular a corresponding series of separate 1-pole switches corresponding terminal pitch, a divider is used as a spacer between two Einzelpolblöcke whose width corresponds to twice the thickness of the housing wall.

Der Erfindung liegt die Aufgabe zugrunde, einen 3- oder 4-poligen Schutzschalter anzugeben, der mit besonders geringem fertigungstechnischen Aufwand herstellbar ist.The invention has for its object to provide a 3- or 4-pole circuit breaker, which can be produced with very little manufacturing effort.

Diese Aufgabe wird durch Anspruch 1 gelöst. Zur Lösung wird auf zwei bereits vorhandene, 2-polige Überstromschutzschalter zurückgegriffen, wie sie aus der DE 27 21 162 C2 bekannt sind.

Die Zwischenwand ist dabei rechtwinklig zur Reihenrichtung der beiden 2-poligen Doppelschalter bzw. der in ihnen zu einer Baugruppe zusammengefassten Einzelschalter ausgerichtet. Sie bildet dabei etwa eine Symmetrieebene für den etwa raumsymmetrischen, 3- oder 4-poligen Überstromschutzschalter. Dabei bildet die Zwischenwand gewissermaßen das Rückgrat des als Montageeinheit zusammengestellten 3- oder 4-poligen Überstromschutzschalters, welcher nachstehend aus Gründen der sprachlichen Vereinfachung kurz auch als "Kombinationsschalter" bezeichnet wird.This object is solved by claim 1.

Auch an den in der Montageeinheit 11 außenliegenden Seiten der Bodenwände 25 sind in Reihenrichtung 3 vorstehende Fixiernasen zur Schnappfixierung der Montageeinheit 11 an der gegenüberliegenden Gehäuseseitenwand 30 angeordnet. Sie stehen in mit ihnen korrespondiere Fixierausnehmungen 31 der Gehäusewand 30 hinein und sind mit ihnen verschnappt.Also on the outer side in the mounting unit 11 sides of the bottom walls 25 3 projecting fixing lugs for snap fixing of the mounting unit 11 are arranged on the opposite side housing side wall 30 in the row direction. They stand in corresponding with them Fixierausnehmungen 31 of the housing wall 30 in and are snapped with them.

Die der Funktionskopplung zwischen den Einzelschaltem 6-9 dienenden Achsen 12-15 liegen lose in den zugeordneten Funktions- oder Bewegungsteilen ein und sind durch die Gehäuseseitenwände 30,32 in Reihenlängsrichtung 3 verschiebegesichert.The functional coupling between the Einzelschaltem 6-9 serving axes 12-15 are loosely in the associated functional or moving parts and are verschiebegesichert by the housing side walls 30,32 in the longitudinal direction 3.

Die Funktionsweise und die Funktionskinematik der Einzelschalter 6,9 ist eine solche nach DE 27 21 162 C2. Sie wird weiter unten im Einzelnen beschrieben. Die Handbetätigungseinrichtung der Montageeinheit 11 ist ein sich in Reihenrichtung 3 über die gesamte Breite der Montageeinheit 11 erstreckender gemeinsamer Kipphebel 33 als Schaltwippe. Es sind weiterhin zwei im Bereich der Hebelenden 34,35 des Kipphebels 33 um jeweils eine nicht dargestellte, zur Reihenrichtung 3 parallele Achse zu drehbarer Lagerung aufgeschnappte Druckbetätigungstasten 36,37 vorhanden, die in Längsführungen 38,39 der Gehäusestimseite 40 längsverschiebbar geführt sind.The operation and the function kinematics of the individual switch 6.9 is such a DE 27 21 162 C2. It will be described in detail below. The manual override device of the assembly unit 11 is a common rocker arm 33 extending in the row direction 3 over the entire width of the assembly unit 11 as a rocker switch. There are also two in the region of the lever ends 34,35 of the rocker arm 33 each have a not shown, parallel to the row direction 3 axis snapped to rotatable storage Druckbetätigungstasten 36,37 available, which are guided in longitudinal guides 38,39 the Gehäusestimseite 40 longitudinally.

An die Unterseite der Montageeinheit 11 ist ein Anbaufunktionsteil 41 ansetzbar, insbesondere aufschnappbar bzw. anschnappbar. Die Fixierung solcher Anbaufunktionsteile 41 erfolgt bevorzugt an der Zwischenwand 10, genauer gesagt an deren Unterkante.At the bottom of the mounting unit 11 is a cultivation functional part 41 can be attached, in particular snapped or snapped on. The fixing of such attachment functional parts 41 is preferably carried out on the intermediate wall 10, more precisely on the lower edge thereof.

Die Gehäusestirnwand 40 steht als Anlageflansch über die Gehäuseseitenwände 30,32 hinaus. Die Gehäuseseitenwände 42,43 sind auf ihren Außenseiten mit federnden Rastarmen 44 zum Einrasten der Montageeinheit 11 in ein Paneel (nicht dargestellt) versehen.The housing end wall 40 projects beyond the housing side walls 30, 32 as an abutment flange. The housing side walls 42,43 are provided on their outer sides with resilient locking arms 44 for engaging the mounting unit 11 in a panel (not shown).

Anhand der Fig. 2 und 3 wird die Funktionsweise sowohl einer 2-poligen Schalterbaugruppe 1 bzw. 2 als auch der 3- oder 4-poligen Montageeinheit, also des Kombinationsschalters, im Einzelnen erläutert. Diese Funktionsweise stimmt mit der im Einzelnen in DE 27 21 162 C2 beschriebenen Funktionsweise überein und auch die dortige Beschreibung wird zum Gegenstand der vorliegenden Erfindungsoffenbarung gemacht.2 and 3, the operation of both a 2-pin switch assembly 1 and 2 and the 3- or 4-pin mounting unit, so the combination switch, explained in detail. This mode of operation is consistent with the operation described in detail in DE 27 21 162 C2 and also the description there is made the subject of the present invention disclosure.

Fig. 1 und 2 zeigen den Kombinationsschalter in Einschaltstellung, also in Kontaktschließstellung. Alle Funktionsteile der Schalterbaugruppen 1,2 sind an einem Gehäusesockel 51 fixiert oder gelagert, dessen Rückgrat gewissermaßen die Trennwand 4 bzw. 5 bildet. Der Stromverlauf erfolgt vom Anschluss 52 über die Kontaktfeder 53 und über den mit ihr fest verbundenen Kontaktniet 54 zum Festkontakt 55, welcher mit dem anderen Anschluss 56 verbunden ist. Der kontaktdruck wird durch den Verklinkungshebel 57 erzeugt. Dieser Verklinkungshebel 57 stützt sich in Einschaltstellung bzw. in Kontaktschließstellung am Rastanschlag 58 des Winkelhebels 59 ab. Dieser Rastanschlag 58 bildet in der Einschaltstellung des Systems einen Drehpunkt des Verklinkungshebels 57, dessen Stellung durch gegenläufige Drehmomente bestimmt wird.Fig. 1 and 2 show the combination switch in closed position, ie in contact closing position. All functional parts of the switch assemblies 1, 2 are fixed or mounted on a housing base 51, the backbone of which as it were forms the partition 4 or 5. The course of current takes place from the connection 52 via the contact spring 53 and via the contact rivet 54 fixedly connected to it to the fixed contact 55, which is connected to the other connection 56. The contact pressure is generated by the Verklinkungshebel 57. This Verklinkungshebel 57 is based in closed position or in contact closed position on the locking stop 58 of the angle lever 59 from. This latching stopper 58 forms in the closed position of the system a pivot point of the Verklinkungshebels 57, whose position is determined by opposing torques.

Das eine Drehmoment wird durch die Achse 14 aufgebracht. Die Achse 14 ist fest im Kipphebel 33 geführt. Sie verläuft lotrecht zur Bildebene von Fig. 2 und 3, nämlich in Reihenrichtung 3. Sie durchsetzt den Verklinkungshebel 57 in einer Nut 60 und diese Nut 60 hat die Form eines auf dem Kopf stehenden V.The one torque is applied through the axle 14. The axle 14 is firmly guided in the rocker arm 33. It runs perpendicular to the image plane of Fig. 2 and 3, namely in the row direction 3. It passes through the Verklinkungshebel 57 in a groove 60 and this groove 60 has the shape of an upside-down V.

Der Kipphebel 33 indessen ist über die Achse 13 drehbar am Sockel 51 bzw. an dessen Trennwand 4 drehbar gelagert und durch die Rückstellfeder 61 mit einem in die Ausschaltstellung gerichteten Permanentdruck beaufschlagt. Gegenläufig zu dieser Druckbeaufschlagung ist ein anderes Drehmoment wirksam, welches die Kontaktfeder 53 auf den Verklinkungshebel 57 ausübt. Dieses gegenläufige Drehmoment sorgt in Einschaltstellung, d.h. bei auf dem Rastanschlag 58 aufliegendem Verklinkungshebel 57 dafür, dass die Achse 14 nicht über den Scheitelpunkt 62 der V-förmigen Nut 60 hinwegrutschen kann.The rocker arm 33, however, is rotatably supported on the base 51 and on the partition wall 4 rotatably about the axis 13 and by the return spring 61 with a acted upon in the open position directed permanent pressure. Opposite to this pressurization another torque is effective, which exerts the contact spring 53 on the Verklinkungshebel 57. This opposing torque ensures in closed position, ie when resting on the latching stop 58 Verklinkungshebel 57 that the axis 14 can not slip over the vertex 62 of the V-shaped groove 60.

Die Auslösung bzw. Ausschaltung eines jeden Einzelschalters und dadurch des Kombinationsschalters bzw. der Montageeinheit kann nun einerseits manuell durch Druck auf die rechte Druckbetätigungstaste 36 bewirkt werden. Dadurch wird die von der Rückstellfeder 61 ausgeübte Druckkraft derart unterstützt, dass das von der Achse 14 bewirkte Drehmoment groß genug wird, um den Scheitelpunkt 62 der V-förmigen Nut 60 zu überwinden. Jetzt sorgt die Achse 14 zusammen mit der Kontaktfeder 53 für eine Kontaktöffnung des Systems. Die Kontaktfeder 53 ist nämlich in Kontaktöffnungsrichtung vorgespannt.The triggering or switching off of each individual switch and thereby of the combination switch or the assembly unit can now be effected on the one hand manually by pressing the right push-button 36. As a result, the compressive force exerted by the return spring 61 is assisted such that the torque produced by the axle 14 becomes large enough to overcome the apex 62 of the V-shaped groove 60. Now the axis 14 together with the contact spring 53 provides for a contact opening of the system. Namely, the contact spring 53 is biased in the contact opening direction.

Andererseits kann die Kontakttrennung, also die Auslösung bzw. Ausschaltung des Geräts, durch Beaufschlagung des Wirkendes 63 des Winkelhebels 59 mit einer Kraft vollzogen werden, die beispielsweise durch ein stromdurchflossenes Bimetall 64 oder durch den Öffnungsstößel (nicht dargestellt) eines Anbauteiles 41 bewirkt wird. Dadurch wird der Rastanschlag 58 des Winkelhebels 59 infolge einer Drehung des Winkelhebels 59 im Gegenuhrzeigersinn um seine Schwenkachse 65 aus seiner Stützstellung für die Rastnase 66 des Verklinkungshebels 57 weggeschwenkt. Dadurch wird der Verklinkungshebel 57 frei, so dass die von der Achse 14 und der Kontaktfeder 53 erzeugten Drehmomente die Kontaktöffnung bewirken.On the other hand, the contact separation, ie the triggering or switching off of the device, by applying the action end 63 of the angle lever 59 can be performed with a force that is effected for example by a current-carrying bimetal 64 or by the opening plunger (not shown) of an attachment 41. As a result, the latching stop 58 of the angle lever 59 is pivoted away as a result of rotation of the angle lever 59 in the counterclockwise direction about its pivot axis 65 from its supporting position for the latching nose 66 of Verklinkungshebels 57. Thereby, the Verklinkungshebel 57 is free, so that the torques generated by the axis 14 and the contact spring 53 cause the contact opening.

Entfällt die auf den Winkelhebel 59 einwirkende Kraftbeaufschlagung beispielsweise durch das Bimetall 64 oder den Stößel des Anbaufunktionsteils, so wird der Winkelhebel 59 durch die Drehfeder 67 wieder zurückgestellt, so dass der Schalter wieder eingeschaltet wird (Kontaktschließstellung).If the action of force acting on the angle lever 59 is omitted, for example, by the bimetal 64 or the plunger of the attachment function part, then the angle lever 59 is reset by the torsion spring 67 so that the switch is switched on again (contact closed position).

Der Verklinkungshebel 57 ist U-förmig ausgebildet, so dass er um den Sockel 51 bzw. um die Trennwand 4 bzw. 5 herumgreifen kann. Das geschlossene Ende des U liegt im Bereich der Rastnase 66. Auch der Winkelhebel 59 reicht durch eine Öffnung der Trennwand 4 bzw. 5 mit einem Axialansatz 68 hindurch, wo der andere Pol der Schalterbaugruppe positioniert ist bzw. angebracht sein kann.The Verklinkungshebel 57 is U-shaped so that it can grip around the base 51 and to the partition wall 4 and 5 respectively. The closed end of the U is in the region of the latching nose 66. The angle lever 59 extends through an opening of the partition wall 4 and 5 with an axial extension 68 through, where the other pole of the switch assembly is positioned or can be attached.
