Bewegbare Schal kontaktanordnung mit KontaktkraftfedernMovable scarf contact arrangement with contact force springs
Die Erfindung betrifft eine bewegbare Schaltkontaktanordnung für einen Niederspannungs-Leistungsschalter mit mehreren Kontakthebeln und mit einem die Kontakthebel aufnehmenden Kontakthebeltrager, der ein Widerlager für die Kontakthebel beaufschlagende Kontaktkraftfedern aufweist.The invention relates to a movable switching contact arrangement for a low-voltage circuit breaker with a plurality of contact levers and with a contact lever holder which receives the contact lever and which has an abutment for the contact force springs acting on the contact lever.
Eine Schaltkontaktanordnung mit diesen Merkmalen ist durch die DE 44 16 105 Cl bekanntgeworden. Der Kontakthebeltrager, der aus Metall oder aus Isolierstoff bestehen kann, weist dabei eine Anzahl von Aufnahmeöffnungen für die Kontakt- kraftfedern auf, die als Schraubendruckfedern ausgebildet sind. Sind die Kontakthebel verhältnismäßig schmal, so erweist es sich als zweckmäßig, die insgesamt benötigte Kontaktkraft auf zwei parallele Kontaktkraftfedern je Kontakthebel zu verteilen. Es können dann nämlich Federn verwendet werden, deren Durchmesser die Breite des Kontakthebels nicht übersteigt. Da Niederspannungs- Leistungsschalter entsprechend dem jeweiligen Bemessungsstrom und Schaltvermögen unterschiedlich viele und unterschiedlich breite Kontakthbebel aufweisen können, ist die Anzahl der zur Aufnahme der Kontaktkraftfedern im Kontakthebeltrager vorzusehenden Anzahl von Ausnehmungen dementsprechend gleichfalls sehr unterschiedlich. Dies bedeutet, daß auch dann unterschiedliche Kontakthebeltr ger bereitgestellt werden müssen, wenn zwar bei verschiedener Bemessung von Leistungsschaltern die Gesamtbreite der bewegbaren Sehal kontaktanordnungen übereinstimmt, aber die Anzahl derA switch contact arrangement with these features has become known from DE 44 16 105 Cl. The contact lever carrier, which can consist of metal or insulating material, has a number of receiving openings for the contact force springs, which are designed as helical compression springs. If the contact levers are relatively narrow, it proves to be expedient to distribute the total contact force required over two parallel contact force springs per contact lever. It is then possible to use springs whose diameter does not exceed the width of the contact lever. Since low-voltage circuit breakers can have different numbers and differently wide contact levers depending on the respective rated current and switching capacity, the number of recesses to be provided for receiving the contact force springs in the contact lever carrier is accordingly very different. This means that different Kontakthebeltr ger must be provided even if the total width of the movable with different sizes of circuit breakers Sehal contact arrangements match, but the number of
Kontatkhebel und der zugehörigen Kontaktkraftfedern abweicht.Contact lever and the associated contact force springs deviate.
Der Erfindung liegt die Aufgabe zugrunde, die Herstellung einer Typenreihe von Niederspannungs-Leistungsschaltern durch Verwendung einheitlicher Teile zu erleichtern.The invention has for its object to facilitate the production of a series of low-voltage circuit breakers by using uniform parts.
Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß das Widerlager der Kontaktkraftfedern durch ein mit dem Kontakthebeltr ger zu verbindendes Einsatzstück gebildet ist. Ein solches Einsatzstück ist im Vergleich zu dem gesamten Kontakthebeltrager ein kleines Teil und läßt sich daher preiswert herstellen. Insbesondere können Einsatzstücke mit jeweils angepaßter Anzahl und Verteilung von Aufnahme- Öffnungen für Kontaktkraftfedern hergestellt werden, die jeweils gleiche äußere Abmessungen aufweisen.According to the invention, this object is achieved in that the abutment of the contact force springs is formed by an insert piece to be connected to the contact lever carrier. Such an insert is a small part compared to the entire contact lever carrier and can therefore be manufactured inexpensively. In particular, inserts can be produced with an adapted number and distribution of receiving openings for contact force springs, each having the same outer dimensions.
Nach einer Weiterbildung der Erfindung kann der Kontakthebeltrager eine taschenartige Ausnehmung zur Aufnahme des Einsatzstückes aufweisen, wobei das Einsatzstück mitAccording to a development of the invention, the contact lever carrier can have a pocket-like recess for receiving the insert, the insert having
Aufnahmeöffnungen für die Kontaktkraftfedern in einer dem Abstand der Kontakthebel angepaßten Verteilung versehen ist. Somit können Leiεtungsschalter gleicher Abmessungen, jedoch mit unterschiedlicher elektrischer Bemessung dadurch preiswerter als bisher hergestellt werden, daß einheiticheReceiving openings for the contact force springs is provided in a distribution adapted to the distance between the contact levers. Circuit-breakers of the same dimensions, but with different electrical ratings, can thus be manufactured more cheaply than previously in that uniform

Die Einsatzstücke können zugleich als Abstandshalter für die Kontakthebel ausgebildet sein und können hierzu zwischen den Aufnahmeöffnungen für die Kontaktkraftfedern angeordnete Trennstege und außenliegend je einen Endsteg mit der halbenInsert piece reduced, which is cheap for manufacturing costs. The inserts can at the same time be designed as spacers for the contact levers and can for this purpose separating webs arranged between the receiving openings for the contact force springs and one end web on the outside each with half

Die Erfindung wird im folgenden anhand der in den Figuren dargestellten Ausführungsbeispiele näher erläutert.The invention is explained in more detail below with reference to the exemplary embodiments shown in the figures.
Die Figur 1 zeigt schematisch einen Niederspannungs- Leistungschalter im Schnitt.Figure 1 shows schematically a low-voltage circuit breaker in section.
Eine bewegbare Schaltkontaktanordnung mit einem Einsatzstück für Kontaktkraftfedern ist gesondert teilweise geschnitten in der Figur 2 dargestellt.A movable switching contact arrangement with an insert for contact force springs is shown separately partially cut in Figure 2.
Die Figur 3 zeigt ein Einsatzstück für Kontaktkraftfedern im Schnitt.Figure 3 shows an insert for contact force springs in section.
Die Figuren 4 und 5 sind Ansichten von Einsatzstücken für drei bzw. vier Paare von Kontaktkraftfedern.Figures 4 and 5 are views of inserts for three and four pairs of contact force springs, respectively.
In der Figur 6 ist eine Kombination von drei Einsatzstücken für insgesamt neun Kontakthebel gezeigt. Als weiteres Beispiel für eine Kombination von Einsatzstücken zeigt die Figur 7 zwei zusammengefügte Einsatzstücke für je vier Paare von Kontaktkraftfedern.FIG. 6 shows a combination of three inserts for a total of nine contact levers. As a further example of a combination of insert pieces, FIG. 7 shows two assembled insert pieces for four pairs of contact force springs each.
Der Niederspannungs-Leistungsschalter 1 gemäß der Figur 1 weist ein Gehäuse 2 zur Aufnahme eines SchaltkontaktSystems, einer Lichtbogenlöschkammer 3 und einer zur Betätigung des Schaltkontaktsystens dienenden Antriebsvorrichtung 4 auf. Das Schaltkontaktsystem weist einen feststehenden Schaltkontakt 5 auf, der mit einer oberen Anschlußschiene 6 verbunden ist sowie eine bewegbare Schaltkontaktanordnung 7, zu der ein mit Kontakthebeln 10 bestückter Kontakthebeltrager 11 gehört. Biegsame Leiter 12 dienen zur Verbindung der Kontakthebel 10 mit einer parallel zu der oberen Anschlußεchiene 6 angeordneten unteren Anschlußschiene 13. Zum Ein- und Ausschalten dient die im frontseitigen Teil des Gehäuses 2 untergebrachte Antriebsvorrichtung 4, die mittels einer Schaltwelle 14 und einem mit dieser verbundenen gelenkigen Koppelgestänge 15 auf den Kontakthebeltrager 11 einwirkt. Mehrere Schaltkontakt- Systeme können in bekannter Weise parallel nebeneinander angeordnet und durch eine gemeinsame Antriebsvorrichtung 4 sowie eine gemeinsame Schaltwelle 14 betätigbar sein.The low-voltage circuit breaker 1 according to FIG. 1 has a housing 2 for receiving a switch contact system, an arc quenching chamber 3 and a drive device 4 for actuating the switch contact system. The switch contact system has a fixed switch contact 5, which is connected to an upper connecting rail 6, and a movable switch contact arrangement 7, to which a contact lever carrier 11 equipped with contact levers 10 belongs. Bendable conductors 12 serve to connect the contact levers 10 to a lower connecting rail 13 arranged parallel to the upper connecting rail 6. The drive device 4 accommodated in the front part of the housing 2 is used for switching on and off Coupling linkage 15 acts on the contact lever bracket 11. Several switch contact systems can be arranged in parallel in a known manner next to one another and can be actuated by a common drive device 4 and a common switch shaft 14.
Wie näher die Figur 2 zeigt, sind die Kontakthebel 10 an dem Kontakthebeltrager 11 mittels eines Gelenkbolzens 16 schwenkbar angebracht und durch je zwei Kontaktkraftfedern 17 vorgespannt. Beim Auftreffen der Kontakthebel 10 auf den feststehenden Schaltkontakt 5 schwenken die Kontakthebel 10 um den Gelenkbolzen 16 im Sinne eines Pfeiles 20 gegen dieAs FIG. 2 shows in more detail, the contact levers 10 are pivotably attached to the contact lever bracket 11 by means of an articulated bolt 16 and are prestressed by two contact force springs 17 each. When the contact lever 10 strikes the fixed switching contact 5, the contact lever 10 swings around the hinge pin 16 in the direction of an arrow 20 against the
Wirkung der Kontaktkraftfedern 17.Effect of the contact force springs 17.
Der Kontakthebeltrager 11 ist entsprechend seinen mechanischen und elektrischen Aufgaben ein relativ großer und komplizierter Körper, der ein- oder mehrteilig ausgebildet sein und ganz oder teilweise aus Metall oder isolierendem Kunststoff bestehen kann.According to its mechanical and electrical functions, the contact lever support 11 is a relatively large and complicated body which can be constructed in one or more parts and can consist entirely or partially of metal or insulating plastic.
Eine Vereinfachung der Gestaltung des Kontakthebelträgers 11 wird dadurch erreicht, daß die Kontaktkraftfedern 17 in einem Einsatzstück 21 (Figuren 2 und 3) aufgenommen werden, das in einer taschenartigen Ausnehmung 22 des Kontakthebelträgers 11 unterzubringen ist. In dem Einsatzstück 21 befinden sich Aufnahmeöffnungen 23 {Figur 3) für die Kontaktkraftfedern 17. Das Einsatzstück 21 kann aus Metall oder Kunststoff hergestellt sein.A simplification of the design of the contact lever carrier 11 is achieved in that the contact force springs 17 are received in an insert piece 21 (FIGS. 2 and 3) which is to be accommodated in a pocket-like recess 22 in the contact lever carrier 11. In the insert 21 there are receiving openings 23 (FIG. 3) for the contact force springs 17. The insert 21 can be made of metal or plastic.
Obwohl es möglich ist, Einsatzstücke 21 für die jeweils benötigte gesamte Anzahl von Kontaktkraftfedern herzustellen, kann es günstiger sein, zwei oder mehrere kleinere Einsatzstücke miteinander zu kombinieren. Als Beispiel für eine solche modulartige Bauweise zeigt die Figur 4 ein Einsatzstück 24 für drei Paare von Kontaktkraftfedern, während ein Einsatzstück 25 gemäß der Figur 5 für vier Paare von Kontaktkraftfedern bemessen ist. Aus diesen Einsatzstücken 24 bzw. 25 sind Kombinationen zusammensetzbar, wie sie die Figuren 6 und 7 zeigen. Offensichtlich kann der Fachmann anhand dieser Beispiele auch Kombinationen beider Einsatzstücke in Betracht ziehen, um beliebige Anzahlen von Kontakthebeln mit Kontaktkraftfedern zu versehen. Als Anhalt kann die nachfolgende Tabelle dienen.Although it is possible to produce insert pieces 21 for the total number of contact force springs required in each case, it may be more advantageous to combine two or more smaller insert pieces with one another. As an example of such a modular construction, FIG. 4 shows an insert 24 for three pairs of contact force springs, while an insert 25 according to FIG. 5 is dimensioned for four pairs of contact force springs. Combinations can be assembled from these insert pieces 24 and 25, as shown in FIGS. 6 and 7. Obviously, on the basis of these examples, the person skilled in the art can also consider combinations of both insert pieces in order to obtain any number of To provide contact levers with contact force springs. The table below can serve as a guide.

Werden Einsatzstücke mit anderen Anzahlen von Aufnahmeoffnungen versehen, so ergeben sich entsprechende andere bzw. weitere Möglichkeiten der Kombination.If insert pieces are provided with different numbers of receiving openings, corresponding other or further possibilities of the combination result.
In den Figuren 3 bis 7 ist außerdem gezeigt, daß jeweils zwischen einem Paar von Aufnahmeoffnungen 23 ein Trennsteg 26 angeordnet ist. Dieser verbessert die Führung der Kontaktkraftfedern 17 und kann auch als Abstandshalter der Kontakthebel 10 (Figur 2) dienen. Jeweils außen sind die Einsatzstücke 24 und 25 mit einem Endsteg 27 versehen, der die halbe Breite der Trennstege 26 besitzt. Dadurch entsteht beim Zusammenfügen von Einsatzstücken insgesamt ein Abstand entsprechend den Trennstegen 26. FIGS. 3 to 7 also show that a separating web 26 is arranged in each case between a pair of receiving openings 23. This improves the guidance of the contact force springs 17 and can also serve as a spacer for the contact lever 10 (FIG. 2). The inserts 24 and 25 are each provided on the outside with an end web 27 which has half the width of the separating webs 26. This results in a total distance corresponding to the separating webs 26 when joining inserts.
