Abstract

The connecting terminal (7) (which is designed for attachment onto a busbar (12)), of a panel apparatus, whose housing (1) is attached on a supporting profile rail (2) has a terminal plate (8) and a terminal nut (10) on a screw (11). The terminal plate (8) has two limbs (14) on the side, each having a longitudinal guide slot (15), which has a section (17) angled towards the housing (1) in its end in the region of the free end of the limb (14). The terminal nut (10) has tabs (16) which are guided in the slots (15). On releasing the screw (11), the tabs (16) enter into the angled sections (17) of the guide slots (15), so that the terminal nut (10) is displaced behind the front surface of the housing (1) and no longer projects beyond this front surface, with the screw (11) being pushed into an inclined position. The housing (1) can therefore be raised on its front side without any hindrance from the busbar (12), and can be removed from the supporting profile rail (2). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Anschlussklemme an einem zur Verwendung in einer elektrischen Niederspannungs-Installationsanlage bestimmten Einbauapparat gemäss dem Oberbegriff des Patentanspruchs 1. Ein derartiger Einbauapparat kann beispielsweise ein Leitungsschutzschalter, ein Einbau-Sicherungselement oder dgl. sein.The invention relates to a connection terminal on a built-in apparatus for use in an electrical low-voltage installation system according to the preamble of patent claim 1. Such a built-in apparatus can be, for example, a circuit breaker, a built-in fuse element or the like.

Es ist üblich, für die Montage solcher Einbauapparate in der Installationsanlage, z.B. in einem Verteilerkasten, Tragprofile genormter Form und einheitlicher Abmessungen zu verwenden, z.B. Schienen 35 mm nach DIN 46277. Der Einbauapparat, der an seinem Boden eine entsprechende Ausnehmung in schwalbenschwanzähnlicher Ausbildung aufweist, wird auf dieses Tragprofil aufgesetzt und auf ihm mittels eines am Gehäuse des Einbauapparats angeordneten federnden Schiebers festgehalten.It is common for the installation of such built-in devices in the installation system, e.g. to be used in a distribution box, support profiles of standardized shape and uniform dimensions, e.g. Rails 35 mm according to DIN 46277. The installation device, which has a corresponding recess in the shape of a dovetail on its base, is placed on this support profile and held on it by means of a resilient slide arranged on the housing of the installation device.

Um den Installationsaufwand möglichst gering zu halten, ist es ferner üblich, die Einbauapparate mit speiseseitigen Anschlussklemmen zu versehen, die alle bezüglich der genannten Ausnehmung für das Tragprofil den gleichen Abstand in seitlicher Richtung und in Höhenrichtung haben und die zum Einklemmen einer Sammelschiene ausgebildet sind. Es ist dann möglich, bei der Montage einen Einbauapparat nach dem andern auf das Tragprofil aufzustecken und hierauf die Sammelschiene in die Anschlussklemmen aller aufgesteckten Einbauapparate einzulegen, worauf zur Herstellung der Speiseanschlüsse nur noch die Schrauben der Anschlussklemmen der einzelnen Einbauapparate angezogen werden müssen.In order to keep the installation effort as low as possible, it is also customary to provide the built-in apparatuses with feed-side connection terminals, all of which with respect to those mentioned Recess for the support profile have the same distance in the lateral direction and in the vertical direction and which are designed for clamping a busbar. It is then possible to mount one installation device after the other on the support profile and then insert the busbar into the connection terminals of all plug-in installation devices, after which only the screws of the connection terminals of the individual installation devices need to be tightened to make the supply connections.

Tritt nun bei einer solchen fertiggestellten Installationsanlage in einem späteren Zeitpunkt die Notwendigkeit ein, einen einzelnen Einbauapparat aus der Reihe der mehreren, auf dem gleichen Tragprofil angeordneten und an die gleiche Sammelschiene angeschlossenen Einbauapparate zu entfernen bzw. auszuwechseln, so begegnet man erheblichen Schwierigkeiten. Zwar kann der Einbauapparat durch Anheben an der Seite seines federnden Schiebers grundsätzlich vom Tragprofil abgehoben werden. Eine solche Schwenkbewegung wird aber durch die über das Gehäuse des Einbauapparats auch nach dem Lösen der Schraube der Anschlussklemme vorstehende Klemmmutter, die ja die Sammelschiene untergreifen muss, gehindert. Somit ist es erforderlich, zum Entfernen eines einzelnen Einbauapparats vom Tragprofil alle auf der einen Seite des betreffenden Einbauapparats montierten Einbauapparate ebenfalls zu entfernen, was einen beträchtlichen Zeitaufwand zur Folge hat.If such a completed installation system later needs to remove or replace a single installation device from the series of the plurality of installation devices arranged on the same support profile and connected to the same busbar, considerable difficulties are encountered. The built-in apparatus can basically be lifted off the support profile by lifting it on the side of its resilient slide. However, such a pivoting movement is prevented by the clamping nut projecting beyond the housing of the built-in apparatus even after the screw of the connecting terminal has been loosened, which nut has to reach under the busbar. It is therefore necessary, in order to remove an individual installation apparatus from the support profile, likewise all installation apparatuses installed on one side of the installation apparatus concerned to remove, which takes a considerable amount of time.

Aufgabe der Erfindung ist, eine Anschlussklemme der eingangs genannten Art derart auszubilden, dass bei gelöster Schraube der Anschlussklemme eine Schwenkbewegung des Einbauapparats in einer zur Sammelschiene senkrechten Ebene ermöglicht ist.The object of the invention is to design a connection terminal of the type mentioned at the outset in such a way that when the connection terminal is loosened, a pivoting movement of the installation apparatus is made possible in a plane perpendicular to the busbar.

Zur Lösung dieser Aufgabe weist die erfindungsgemässe Anschlussklemume die im kennzeichnenden Teil des Patentanspruchs 1 angeführten Merkmale auf.To achieve this object, the connection terminal according to the invention has the features stated in the characterizing part of patent claim 1.

Da sich bei der erfindungsgemässen Anschlussklemme Führungsschlitze für die Klemmutter nicht nur senkrecht zur Stromschiene in Richtung der Schraube erstrecken, sondern in ihrem letzten Abschnitt auch schräg zur Stromschiene, wird bei fortgesetztem Lösen der Schraube die Klemmutter in Richtung des Gehäuses des Einbauapparats verschoben, so dass sie unterhalb der Stromschiene aus deren Begrenzungsbereich rückt. Somit kann dann der Einbauapparat auf der Seite der Stromschiene über die Stromschiene hinaus angehoben und dadurch aus dem Tragprofil entfernt werden.Since guide slots for the clamping nut not only extend perpendicular to the busbar in the direction of the screw in the connection terminal according to the invention, but also obliquely to the busbar in their last section, the clamping nut is displaced in the direction of the housing of the installation apparatus when the screw is loosened again below the conductor rail moves out of its boundary area. The built-in apparatus on the side of the busbar can then be raised above the busbar and thereby removed from the support profile.

Ein Ausführungsbeispiel des Erfindungsgegenstandes wird nachstehend anhand der Zeichnungen erläutert. Es zeigen:

  • Fig. 1 eine Seitenansicht der erfindungsgemässen, mit einer Stromschiene verbundenen Anschlussklemme im Gehäuse eines auf einem Tragprofil montierten Einbauapparats,
  • Fig. 2 einen Schnitt längs der Linie II - II in Fig. 1,
  • Fig. 3 eine Seitenansicht entsprechend Fig. 1 mit gelöster Schraube der Anschlussklemme und einseitig angehobenem Gehäuse des Einbauapparats.
An embodiment of the subject matter of the invention is explained below with reference to the drawings. Show it:
  • 1 is a side view of the connecting terminal according to the invention connected to a busbar in the housing of a built-in apparatus mounted on a support profile,
  • 2 shows a section along the line II-II in FIG. 1,
  • F ig. 3 is a side view corresponding to FIG. 1 with the screw of the connection terminal loosened and the housing of the installation apparatus raised on one side.

Gemäss Fig. 1 ist ein Einbauapparat, z.B. ein Leitungsschutzschalter, mit seinem Gehäuse 1 in an sich bekannter Weise auf einer Tragschiene 2 von etwa C-förmiger Profilform befestigt, wobei ein im Gehäuse 1 angeordneter, federbelasteter Schieber 3 das Gehäuse 1 auf der Tragschiene 2 festhält.1 is a built-in apparatus, e.g. a circuit breaker, with its housing 1 fastened in a manner known per se on a mounting rail 2 of approximately C-shaped profile shape, a spring-loaded slide 3 arranged in the housing 1 holding the housing 1 on the mounting rail 2.

Im Gehäuse 1 ist zwischen einer Gehäuseschale 4 (Fig. 2), welche auch einen Gehäuseboden 5 bildet, und einem Gehäusedeckel 6, der in Fig. 1 teilweise weggeschnitten dargestellt ist, eine speiseseitige Anschlussklemme 7 angeordnet. In an sich bekannter Weise besteht die Anschlussklemme 7 aus einer Klemmplatte 8, unterhalb welcher zudem eine Kontaktplatte 9 angeordnet ist, aus einer Klemmutter 10 und einer Klemmschraube 11, -deren Kopf auf der Klemmplatte 8 aufliegt und auf welche die Klemmutter 10 geschraubt ist. Im angeschlossenen Zustand gemäss Fig. 1 ist eine Sammelschiene 12 mit rechteckigem Querschnitt zwischen der Klemmplatte 8 mit unterlegter Kontaktplatte 9 und der Klemmutter 10 eingeklemmt, wobei die Kontaktplatte 9 über ein Leiterstück 13 eine elektrische Verbindung von der Sammelschiene 12 zu einem nicht dargestellten, von der Sammelschiene 12 zu speisenden Teil des Einbauapparates 1 herstellt.In the housing 1, a feed-side connection terminal 7 is arranged between a housing shell 4 (FIG. 2), which also forms a housing base 5, and a housing cover 6, which is shown partially cut away in FIG. 1. In a manner known per se, the connecting terminal 7 consists of a clamping plate 8, below which a contact plate 9 is also arranged, a clamping nut 10 and a clamping screw 11, the head of which rests on the clamping plate 8 and to which the clamping nut 10 is screwed. In the connected state according to FIG. 1, a busbar 12 with a rectangular cross section is clamped between the clamping plate 8 with the underlying contact plate 9 and the clamping nut 10, the contact plate 9 making an electrical connection via a conductor piece 13 from the busbar 12 to a not shown, from the Busbar 12 produces part of the built-in apparatus 1 to be fed.

Die Klemmplatte 8 ist mit zwei seitlichen Schenkeln 14 versehen, die sich in der Längsrichtung der Schraube 11 erstrecken und mit der Klemmplatte 8 einstückig ausgebildet sind, so dass sie mit der Klemmplatte 8 zusammen einen Klemmbügel bilden. Beide Schenkel 14 sind mit je einem Längsschlitz 15 versehen, in welchem je ein nockenartiger Vorsprung 16 der Klemmutter 10 geführt ist. Im Bereich der freien Enden der Schenkel 14 haben die Längsschlitze 15 einen Endabschnitt 17, der gegenüber zu dem zur angezogenen Schraube 11 parallelen Teil des Längsschlitzes 15 um etwa 60° abgewinkelt ist. Die Schlitzbreite im Abschnitt 17 ist zur Aufnahme und Führung der Vorsprünge 16 der Klemmutter 10 ausreichend gross. Eine zwischen der Klemmplatte 8 bzw. der darunter befindlichen Kontaktplatte 9 und der Klemmmutter 10 auf-der Schraube 11 angeordnete Feder 18 bewirkt, dass beim Lösen der Schraube 11 die Klemmutter 10 längs der Schlitze 15 nach unten gedrückt wird.The clamping plate 8 is provided with two lateral legs 14, which extend in the longitudinal direction of the screw 11 and are formed in one piece with the clamping plate 8, so that together they form a clamping bracket with the clamping plate 8. Both legs 14 are each provided with a longitudinal slot 15, in each of which a cam-like projection 16 of the clamping nut 10 is guided. In the area of the free ends of the legs 14, the longitudinal slots 15 have an end section 17 which is angled by approximately 60 ° with respect to the part of the longitudinal slot 15 which is parallel to the tightened screw 11. The slot width in section 17 is sufficiently large to accommodate and guide the projections 16 of the clamping nut 10. A spring 18 arranged on the screw 11 between the clamping plate 8 or the contact plate 9 underneath it and the clamping nut 10 causes that when the screw 11 is loosened, the clamping nut 10 is pressed downward along the slots 15.

Wenn ein Einbauapparat mit Gehäuse 1, der gemäss Fig. 1 auf der Tragschiene 2 befestigt und an die Sammelschiene 12 angeklemmt ist, und der sich zwischen unmittelbar angrenzenden, in gleicher Weise angeordneten Nachbar-Einbauapparaten befindet, aus irgend einem Grund von der Tragschiene 2 entfernt werden soll, muss natürlich zuerst seine Verbindung mit der Sammelschiene 12 durch Lösen der Schraube 11 gelöst werden. Da hierbei die Klemmutter 10 unverändert über die Vorderseite des Gehäuses 1 hinausragt, ist es unmöglich, durch Schwenken des Gehäuses 1 gemäss Fig. 3 dieses aus seiner Verankerung in der Tragschiene 2 zu befreien, da ein Schwenken durch Anschlagen der Klemmutter 10 an der Sammelschiene 12 behindert ist. Wird jedoch bei der vorliegenden Anschlussklemme die Schraube 11 weiter gedreht, als dies zum Abheben der Klemmmutter 10 von der Sammelschiene 12 nötig ist, so gleiten die nockenartigen Vorsprünge 16 der Klemmutter 10 in den abgewinkelten Abschnitt 17 der Führungsschlitze 15, so dass die Klemmutter 10 unter Schrägstellung der Schraube 11 in Richtung zum Innern des Gehäuses 1 verschoben wird, wie dies in Fig. 3 dargestellt ist. Da die Klemmutter 10 jetzt nicht mehr über die Vorderseite, d.h. die der Sammelschiene 12 gegenüberliegende Seite, des Gehäuses vorsteht, kann das Gehäuse 1 entsprechend Fig. 3 an seiner Vorderseite angehoben werden, bis der federnde Schieber 3 über die Tragschiene 2 geglitten ist, und dann vollständig von der Tragschiene 2 abgehoben werden. In gleicher Weise und umgekehrter Reihenfolge erfolgt der Wiedereinbau eines Einbauapparates, der die be- schriebene Anschlussklemme 7 enthält.If a built-in apparatus with housing 1, which is fastened to the mounting rail 2 and clamped to the busbar 12 as shown in FIG. 1 and which is located between immediately adjacent, similarly arranged adjacent mounting apparatuses, is removed from the mounting rail 2 for some reason , its connection to the busbar 12 must of course first be released by loosening the screw 11. Since the clamping nut 10 projects unchanged beyond the front of the housing 1, it is impossible to free it from its anchoring in the mounting rail 2 by pivoting the housing 1 g according to FIG. 3, since pivoting by striking the clamping nut 10 on the busbar 12 is disabled. However, if the screw 11 is rotated further in the present connection terminal than is necessary to lift the clamping nut 10 off the busbar 12, the cam-like projections 16 of the clamping nut 10 slide into the angled section 17 of the guide slots 15, so that the clamping nut 10 underneath Inclination of the screw 11 is shifted towards the inside of the housing 1, as shown in Fig. 3. Since the clamping nut 10 is no longer on the front, ie the busbar 12 against 3 protrudes, the housing 1 can be raised on its front side according to FIG. 3 until the resilient slide 3 has slid over the mounting rail 2, and then be lifted off the mounting rail 2 completely. In the same way and in the reverse order, the installation of an installation apparatus which contains the described connection terminal 7 is carried out.

Um das Schrägstellen der Schraube 11 beim Verschieben der Klemmutter 10 längs des abgewinkelten Abschnitts 17 der Führungsschlitze zu erleichtern, ist es von Vorteil, die Schraubenlöcher in der Klemmplatte 8 und in der Kontaktplatte 9 in Richtung zur Sammelschiene geringfügig länglich auszubilden. Falls auf der Klemmplatte 8 und der Kontaktplatte 9 in Richtung zum Innern des Gehäuses entsprechender Platz vorhanden ist, können diese Schraubenlöcher auch eigentliche Langlöcher sein, damit die Schraube 11 ohne Einnahme einer Schräglage zum Gehäuse hin verschoben wird, wenn beim fortgesetzten Lösen der Schraube die Klemmutter 10 sich längs des abgewinkelten Abschnitts 17 der Führungsschlitze bewegt.In order to facilitate the inclination of the screw 11 when moving the clamping nut 10 along the angled section 17 of the guide slots, it is advantageous to make the screw holes in the clamping plate 8 and in the contact plate 9 slightly elongated in the direction of the busbar. If there is sufficient space on the clamping plate 8 and the contact plate 9 in the direction of the inside of the housing, these screw holes can also be actual elongated holes so that the screw 11 is displaced towards the housing without taking an inclined position if the clamping nut is released when the screw is loosened again 10 moves along the angled portion 17 of the guide slots.

Eine weitere Ausführungsform der erfindungsgemässen Anschlussklemme besteht darin, dass die Führungsschlitze 15 mit ihren abgewinkelten"Endabschnitten 17 nicht in hierfür ausgebildeten Schenkeln 14 der Klemmplatte 8 vorgesehen sind, sondern in entsprechenden Wandteilen des Gehäuses 1, also vorzugsweise in der Gehäuseschale 4 und im Gehäusedeckel 6, vgl. Fig. 2. Die Schenkel 14 der Klemmplatte 8 entfallen dann.A further embodiment of the connecting terminal according to the invention consists in that the guide slots 15 with their angled "end sections 17 are not designed for this purpose th legs 14 of the clamping plate 8 are provided, but in corresponding wall parts of the housing 1, that is, preferably in the housing shell 4 and in the housing cover 6, cf. Fig. 2. The legs 14 of the clamping plate 8 are then omitted.
