Description

Die Erfindung betrifft ein Rahmenklemmelement für elektromechanische Schaltgeräte mit integriertem Anschlussstück, aufweisend einen Rahmen mit einem Gewinde für eine Anschlussschraube.The invention relates to a frame clamping element for electromechanical switching devices with integrated connector, comprising a frame with a thread for a terminal screw.

Eine derartige Klemmanordnung, die an einem Gehäuse eines elektromechanischen Schaltgeräts anzubringen ist, stellt eine elektrische Verbindung zwischen dem Inneren des elektrischen Geräts und der Peripherie her. Angeschlossen werden können auf diese Weise insbesondere Sensoren, Aktuatoren und auch eine Energieversorgung des Geräts.Such a clamping arrangement, which is to be attached to a housing of an electromechanical switching 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 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 Entriegelungsöffnung 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 unlocking 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 Klemmreihen. Bei derartigen mehrstöckigen Klemmeinheiten ist aber der Platzbedarf sowohl an der Gehäuseaußenseite als auch im Gehäuseinneren relativ hoch. Innerhalb des Gehäuses des elektrischen Geräts steht somit weniger Platz für andere Funktionselemente, wie zum Beispiel entsprechend bestückten Leiterplatinen, zur Verfügung.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 each other terminal rows. In such multi-level clamping units but is the Space required both on the outside of the case and inside the housing relatively high. Within the housing of the electrical device is thus less space for other functional elements, such as appropriately populated printed circuit boards, available.

In Haus- und Industrieinstallationen eingesetzte Schaltgeräte 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 Schaltgeräts verbunden. Die elektrische Verbindung zwischen einem zu schützenden äußeren Stromkreis und den Abgangsklemmen 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.Used in home and industrial installations switching devices with insulating material 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 switching device. The electrical connection between an outer circuit to be protected and the output terminals 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.

Neben dieser Schraubtechnik besteht als weitere Leiteranschlussmöglichkeit für elektromechanische Schaltgeräte auch die Möglichkeit, Leiter in Federzugtechnik anzuschließen. Bei großen Geräten werden die Hauptanschlüsse hauptsächlich in Schraubtechnik hergestellt. Diese Hauptanschlüsse werden meist mit großen Rahmenklemmen realisiert.In addition to this screwdriving technology, there is also the option of connecting conductors using spring-cage technology as a further conductor connection option for electromechanical switchgear. For large devices, the main connections are mainly made by screwing. These main connections are usually realized with large box terminals.

Der Nachteil am Stand der Technik besteht darin, dass diese großen Rahmenklemmen für kleine Zusatzverbraucher oder Spannungsabgriffe nicht geeignet sind.The disadvantage of the prior art is that these large box terminals are not suitable for small additional consumers or voltage taps.

Die DE 199 34 550 A1 offenbart ein Kontaktelement einer Anschlussklemme. Das Kontaktelement weist einen etwa U-förmigen Profilabschnitt mit U-Profilschenkeln und einen Basisschenkel auf. An den U-Profilabschnitt schließt sich ein weiteres Teilstück an, das zusammen mit dem U-Profil etwa ein S-Profil bildet. Das Teilstück ist mit einer Zunge verbunden, die in einen Käfig eines Schraubklemmelements eingreift. Das Schraubklemmelement weist eine Klemmschraube auf, die in ein im Käfig vorgesehenes Gewinde eingreift. Zudem ist eine U-förmig gebogene Feder in U-förmigen Profilabschnitt des Kontaktelements angeordnet.The DE 199 34 550 A1 discloses a contact element of a terminal. The contact element has an approximately U-shaped profile section with U-profile legs and a base leg. At the U-profile section closes another Part on, which forms together with the U-profile about an S-profile. The section is connected to a tongue which engages in a cage of a Schraubklemmelements. The Schraubklemmelement has a clamping screw which engages in a provided in the cage thread. In addition, a U-shaped bent spring is arranged in a U-shaped profile section of the contact element.

Demgemäß besteht die Aufgabe der vorliegenden Erfindung darin, ein Rahmenklemmelement für elektromechanische Schaltgeräte zu schaffen, das sowohl eine Anschlussmöglichkeit für Hauptanschlüsse, als auch für kleine Leiter bietet, die beispielsweise für Steuerspannungen oder Nebenverbraucher vorgesehen sind.Accordingly, the object of the present invention is to provide a frame clamping element for electromechanical switching devices, which provides both a connection option for main connections, as well as for small conductors, for example are provided for control voltages or secondary consumers.
