Description

Die Erfindung betrifft einen Leistungsschalter, der auf Federzugtechnik basiert, mit einer Klemmanordnung, die einen L-formigen Grundkörper in Form eines Aufsatzteils mit einem längeren Schenkel und einem kürzeren Schenkel aufweist, wobei am Ende des längeren Schenkels abgewinkelte Verrasthaken angeordnet sind, die in dafür vorgesehene Verrastöffnungen des Leistungsschalters eingreifen und wobei am kürzeren Schenkel nach innen zum Leistungsschalter gerichtete Verschnapphaken angeordnet sind und wobei sich oberhalb des längeren Schenkels mehrere parallel zueinander angeordnete Phasentrennwände befinden.The invention relates to a circuit breaker, which is based on Federzugtechnik, with a clamping arrangement, which has an L-shaped base body in the form of an attachment with a longer leg and a shorter leg, wherein at the end of the longer leg angled Verrasthaken are arranged in the designated Engage Verrastöffnungen the circuit breaker and wherein the shorter limbs are arranged inwardly directed to the circuit breaker Verschnapphaken and wherein above the longer leg a plurality of mutually parallel phase partitions are located.

Eine derartige Klemmanordnung, die an einem Gehause eines elektrischen Gerats anzubringen ist, stellt eine elektrische Vebindung zwischen dem Inneren des elektrischen Gerats und der Peripherie her. Angeschlossen werden können auf diese Weise insbesondere Sensoren, Aktuatoren und auch eine Energieversorgung des Geräts, das zum Beispiel als Schaltgerät ausgeführt ist.Such a clamping arrangement, which is to be attached to a housing of an electrical device, establishes an electrical connection between the interior of the electrical device and the periphery. In particular sensors, actuators and also a power supply of the device, which is designed as a switching device, for example, can be connected in this way.

Es gibt zwei Klemmengrundtypen. Der eine Grundtyp ist die Schraubklemme, bei der eine anzuschließende elektrische Leitung mit der einen Hand in die Klemmstelle eingeführt und dort festgehalten und mit der anderen Hand eine Klemmschraube festgezogen wird. Der andere Klemmengrundtyp ist die Federzugklemme, bei der ein Werkzeug, zum Beispiel ein Schraubendreher, mit der einen Hand in eine Entriegelungsöffnung gesteckt wird, um mit der anderen Hand eine anzuschließende elektrische Leitung in die so entriegelte Klemmstelle einzuführen und dort festzuhalten, bis die Klemmstelle nach Entfernen des Werkzeugs aus der Eritriegelungsöffnung ihre Federklemmwirkung entfaltet hat. Bei beiden Klemmengrundtypen sind also stets die aufeinanderfolgenden Arbeitsschritte "Bestücken" und "Fixieren" erforderlich.There are two basic terminal types. One basic type is the screw terminal, in which a connected electrical line is inserted with one hand in the terminal point and held there and tightened a clamping screw with the other hand. The other basic type of terminal is the spring-type terminal, in which a tool, for example a screwdriver, is inserted with one hand into an unlocking opening, with the other hand to insert an electrical line to be connected in the so-released terminal point and hold it there until the terminal point after Removing the tool from the Eritriegelungsöffnung has unfolded their spring clamping effect. For both basic terminal types, therefore, the sequential steps "assembly" and "fixing" are always required.

Oft werden sehr viele Klemmstellen benötigt, so dass sie nicht alle in Richtung einer Klemm- oder Gehäusebreite nebeneinander angeordnet werden können. Deshalb gibt es mehrstöckige Klemmeinheiten mit mehreren treppenartig über- und zumindest teilweise auch hintereinander angeordneten Klemmenreihen. Bei derartigen mehrstöckigen Klemmeneinheiten ist aber der Platzbedarf sowohl an der Gehäuseaußenseite als auch im Gehäuseinneren relativ hoch. Innerhalb des Gehäuses des elektrischen Gerats steht somit weniger Platz für andere Funktionselemente, wie zum Beispiel entsprechend bestückten Leiterplatinen zur Verfugung.Often a lot of clamping points are needed so that they can not all be arranged side by side in the direction of a clamping or housing width. Therefore, there are multi-level clamping units with several staircase over and at least partially also arranged behind one another terminal rows. In such multi-level terminal units but the space requirement is relatively high both on the outside of the housing and inside the housing. Within the housing of the electrical device is thus less space for other functional elements, such as appropriately equipped printed circuit boards at your disposal.

In Haus- und Industrieinstallationen eingesetzte Leistungsschalter mit Isolierstoffgehäuse sind normalerweise mit Abgangs- und Einspeiseklemmen bestückt, die in zu diesem Zweck auf beiden Seiten des Gehäuses ausgebildeten Klemmaufnahmen angeordnet sind. Die Abgangs- und Einspeiseklemmen sind elektrisch mit den zugeordneten Anschlussbahnen des Leistungsschalters verbunden. Die elektrische Verbindung zwischen einem zu schützenden äußerten Stromkreis und den Ahgangsklemmen beziehungsweise die Verbindung zwischen dem Einspeisenetz und den Einspeiseklemmen erfolgt über Klemmschrauben, die im oberen Teil der genannten Klemmen angeordnet sind. Diese Schrauben weisen im Allgemeinen eine Endgruppe auf, die dazu dient, beim Anziehen gegen den Leiter des betreffenden Stromkreises geführt zu werden, so dass dieser Leiter zwischen der Schraube und der zugehörigen Anschlussfahne festgeklemmt wird.In house and industrial installations used circuit breaker with Isolierstoffgehäuse are usually equipped with outgoing and incoming terminals, which are arranged in this purpose on both sides of the housing formed clamping receptacles. The outgoing and incoming terminals are electrically connected to the associated connection tracks of the circuit breaker. The electrical connection between an outer circuit to be protected and the Ahgangsklemmen or the connection between the feed network and the feed terminals via clamping screws, which are arranged in the upper part of said terminals. These screws generally have an end group which serves to be tightened against the conductor of the circuit in question, so that this conductor between the screw and the associated terminal lug is clamped.

Die EP 1 296 340 A1 beschreibt eine Klemmenabdeckkappe für die Anschlussklemmen eines mehrphasigen elektrischen schaltgerats. Die Klemmenabdeckkappe wird über die Anschlussklemmen eines mehrphasigen elektrischen Schaltgeräts angebracht, um die elektrische Festigkeit zwischen den Anschlussklemmen benachbarter Phasen zu erhöhen. Die L-förmig ausgebildete Klemmenabdeckkappe liegt an ihrer, dem Isolierstoffgehäuse zugekehrten Seiten im Randbereich der zu den Anschlussklemmen führenden Anschlussoffnungen mit einem vernachlässigbar bleinen Luftspalt eng an. In dieser Barriere kann zwischen den Anschlussklemmen die geforderte erhöhte Prüfspannung erhalten werden. An der dem Isolierstoffgehäuse abgekehrten Seite ist die Klemmenabdeckkappe mit Rippen versehen, um den Kriechweg an dieser Stelle der Klemmenabdeckkappe zu verlängern. Die so ausgebildete Klemmenabdeckkappe ermöglicht die Prüfung mit der vorgeschriebenen erhohten Prüfspannung ohne Vergrößerung des Isolierstoffgehäuses für die Verlägerung des Kriechweges zwischen den Anschlussklemmen benachbarter Phasen.The EP 1 296 340 A1 describes a terminal cover for the terminals of a polyphase electrical Schaltterats. The terminal cover is mounted over the terminals of a polyphase electrical switchgear to increase the electrical strength between the terminals of adjacent phases. The L-shaped terminal cover is located on her, the insulating material facing Close sides in the edge area of the port openings leading to the terminals with a negligible lead air gap. In this barrier, the required increased test voltage can be obtained between the terminals. On the side facing away from the insulating housing, the terminal cover cap is provided with ribs in order to extend the creepage distance at this point of the terminal cover cap. The thus formed terminal cover allows the test with the prescribed increased test voltage without increasing the insulating housing for the extension of the creepage distance between the terminals of adjacent phases.

An gewisse Aufbauten beim Leistungsschalter werden die Anforderungen gestellt, dass dieser eingangsseitig eine Ein-Zoll-Luft- und eine Zwei-Zoll-Kriechstrecke aufweist. Bei Schraubgeraten wird dies bisher durch eine zusätzliche Klemme, wie zum Beispiel einer Type E-Klemme, realisiert. Für auf Federzug basierende Leistungsschalter gibt es bisher noch kleine einfache und wirtschaftliche Lösung.On certain structures of the circuit breaker, the requirements are made that the input side has a one-inch air and a two-inch creepage distance. In Schraubgeraten this is previously realized by an additional terminal, such as a Type E terminal. For spring-based circuit breakers there is still a small simple and economical solution.
