Abstract

Bei einer schraubenlosen Klemme ist eine ring- bzw. haarnadelförmig spannbare Klemmfeder (3) vorgesehen, deren eines Ende (5) im gespannten Zustand an dem dem anderen Ende (9) zugeordneten Rastvorsprung (17) verrastbar ist, wobei durch elastisches Verbiegen des anderen Endes (9) von der Außenseite des Gehäuses (2) her die Verrastung aufhebbar und der Leiter (6) durch das freiwerdende eine Ende (5) klemmbar ist. Diese Klemme hat den Vorteil, daß die Federklemme werksseitig in geöffnetem Zustand geliefert werden kann, so daß große Kraftaufwendungen beim Anschließen des Leiters kundenseitig vermieden werden können. Sie ist insbesondere geeignet für Geräte mit einer hohen Anzahl von Klemmen wie elektromagnetische Schaltgeräte.In the case of a screwless clamp, a clamping spring (3) which can be tensioned in the form of a ring or hairpin is provided, one end (5) of which can be locked in the tensioned state on the locking projection (17) assigned to the other end (9), with elastic bending of the other end (9) from the outside of the housing (2) the latching can be released and the conductor (6) can be clamped by the released end (5). This clamp has the advantage that the spring clamp can be delivered in the factory in the open state, so that large amounts of force when connecting the conductor can be avoided by the customer. It is particularly suitable for devices with a large number of terminals, such as electromagnetic switching devices.

Description

Die Erfindung bezieht sich auf eine schraubenlose Anschluß- oder Verbindungsklemme für elektrische Leiter mit einer vor dem Einführen des Leiters zu spannenden und nach dessen Einführen den Leiter klemmenden, in einem Gehäuse angeordneten Klemmfeder, die ring- bzw. haarnadelförmig spannbar ist.The invention relates to a screwless connecting or connecting terminal for electrical conductors with a clamping spring to be tensioned before the insertion of the conductor and after its insertion, which is arranged in a housing and which can be clamped in a ring or hairpin shape.

Bei einer bekannten Klemme der obengenannten Art ist es notwendig, entweder den Draht selbst mit relativ hohem Druck in die Federklemme einzuschieben (DE-AS 1 251 399, DE-AS 2 430 176) oder aber durch Ansetzen eines Werkzeuges, beispielsweise eines Schraubenziehers, unter relativ hohem Druck zu öffnen, um den Leiter einführen zu können (DE-GM 1 898 970). Dies ist in jedem Fall notwendig, wenn feindrähtige Leiter bzw. Litzen ohne Endhülse in der Klemme geklemmt werden müssen. Es sind auch - Klemmen bekannt (DE-AS 20 62 158), wo mit gesonderten Stößeln mit relativ hohem Druck ein Öffnen der Klemme zum Einschieben der Leiter bewirkt werden kann. All diese Klemmen sind jedoch bei elektrischen Schaltgeräten nur mit Schwierigkeiten verwendbar; denn an schlecht zugänglicher Stelle, beiwpielsweise bei Anschlüssen von Hilfsschützen, die in großer Anzahl auf einer Tragplatte angeordnet sind, ist es praktisch nicht möglich, gleichzeitig einen relativ hohen Druck zum Öffnen der Federklemme aufzubringen und das Einführen des Drahtes an der schlecht zugänglichen Stelle durchzuführen. Der erhebliche Kraftaufwand führt zumindest bei Neuinstallation von Geräten zu Ermüdungserscheinungen des Montagepersonals.In a known clamp of the type mentioned above, it is necessary either to insert the wire itself with relatively high pressure into the spring clamp (DE-AS 1 251 399, DE-AS 2 430 176) or by attaching a tool, for example a screwdriver, under open relatively high pressure to be able to insert the conductor (DE-GM 1 898 970). This is necessary in any case if finely stranded conductors or strands without end sleeves have to be clamped in the terminal. There are also - known clamps (DE-AS 20 62 158), where with separate plungers with relatively high pressure an opening of the clamp for inserting the conductors can be effected. However, all of these terminals are difficult to use in electrical switching devices; because in a poorly accessible place, for example when connecting auxiliary contactors, which are arranged in large numbers on a support plate, it is practically not possible to simultaneously apply a relatively high pressure to open the spring clip and to insert the wire in the poorly accessible place. The considerable expenditure of force leads to signs of fatigue of the assembly personnel, at least when new devices are installed.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Klemme zu schaffen, die noch einfacher, insbesondere beim Erstanschluß, zu betätigen ist, ohne hierzu einen hohen Material- und Montageaufwand für die Klemme zu benötigen. Dies wird auf einfache Weise dadurch erreicht, daß das eine Ende der Klemmfeder in gespanntem Zustand an einem dem anderen Ende zugeordneten Rastvorsprung verrastbar ist, wobei durch elastisches Verbiegen des anderen Endes von der Außenseite des Gehäuses her die Verrastung aufhebbar und der Leiter durch das freiwerdende eine Ende klemmbar ist. Hierdurch ergibt sich der Vorteil, daß die Klemme ab Werk im geöffneten Zustand geliefert werden kann, so daß der Kraftaufwand beim Anschließen der Leiter durch den Kunden entfällt. Die Montage des Leiters ist somit relativ einfach. Der Leiter muß lediglich eingelegt werden und die Klemme gelöst werden, d.h. es ist keine Koordinierung zwischen dem Aufbringen des Druckes und dem gleichzeitigen Einschieben des Leiters notwendig. Es sind weiterhin keine zusätzlichen Teile zum Verriegeln,wie Keile oder drehbar gelagerte Verriegelungsorgane notwendig, da die Klemmfeder in sich beide Funktionen, nämlich die Verriegelungsfunktion und die Klemmfunktion, übernimmt. Darüber hinaus sind relativ hohe Auszugskräfte erreichbar, da beim Zug auf den Leiter Selbsthemmung zwischen Leiter und Klemmfeder eintritt. Zumindest bei Verwendung von massiven Drähten, z.B. in der Installationstechnik, kann ein selbsttätiges Schließen der Klemme erreicht werden, indem der Leiter gegen das andere Ende der Klemmfeder zur Auflösung der Rastverbindung stößt. Ein Spannen der Klemmfeder auch zu einem späteren Zeitpunkt und das Lösen von außen wäre möglich, wenn beiden Enden der Klemmfeder gegenüberliegend Gehäuseöffnungen vorgesehen sind. Um mehr oder weniger unabhängig von Fertigungstoleranzen beim Herstellen der Feder zu sein, ist es vorteilhaft, wenn die Klemmfeder einen ausgescherten Rastlappen aufweist. Zusätzliche Halterungsmittel für die Klemmfeder am Gehäuse können eingespart werden, wenn die Klemmfeder in einer Gehäuseausnehmung verrastbar ist. Darüber hinaus können zusätzliche Halterungsmittel für eine Geräteanschlußschiene erspart werden, wenn in der Gehäuseausnehmung zusätzlich eine Geräteanschlußschiene eingelegt ist, die den Gehäuseöffnungen angepaßte Durchbrechungen aufweist, da mindestens jeweils ein Ende der Klemmfeder beim Gerätebetrieb an der Geräteanschlußschiene anliegt.The invention is therefore based on the object of providing a clamp which can be actuated even more easily, in particular when connecting for the first time, without requiring a high outlay in terms of material and assembly for the clamp. This is achieved in a simple manner in that one end of the clamping spring can be locked in the tensioned state at a locking projection assigned to the other end, the locking being able to be canceled by the elastic bending of the other end from the outside of the housing and the conductor being released by the one End is clampable. This has the advantage that the terminal can be delivered from the factory in the open state, so that the effort required by the customer when connecting the conductor is eliminated. The assembly of the conductor is therefore relatively simple. The conductor only has to be inserted and the clamp loosened, ie no coordination between the application of the pressure and the simultaneous insertion of the conductor is necessary. Furthermore, no additional parts for locking, such as wedges or rotatably mounted locking members, are necessary, since the clamping spring takes on both functions, namely the locking function and the clamping function. In addition, relatively high pull-out forces can be achieved, since self-locking occurs between the conductor and the clamping spring when the conductor is pulled. At least when using solid wires, for example in installation technology, the clamp can be automatically closed by pushing the conductor against the other end of the clamp spring to break the snap connection. Tensioning the clamping spring at a later point in time and releasing it from the outside would be possible if housing openings are provided opposite both ends of the clamping spring. In order to be more or less independent of manufacturing tolerances when manufacturing the spring, it is advantageous if the clamping spring has a detached tab. Additional support means for the clamping spring on the housing can be saved if the clamping spring can be locked in a housing recess. In addition, additional mounting means for a device connection rail can be spared if a device connection rail is additionally inserted in the housing recess and has openings adapted to the housing openings, since at least one end of the clamping spring bears against the device connection rail during device operation.

Anhand der Zeichnung werden Ausführungsbeispiele gemäß der Erfindung beschrieben und die Wirkungsweise näher erläutert.Exemplary embodiments according to the invention are described with reference to the drawing and the mode of operation is explained in more detail.

Es zeigen:

  • Fig. 1 eine Ausführungsform der Klemmfeder, bei der zur Verrastung des einen Endes ein Schlitz oder eine Ausnehmung im anderen Ende vorgesehen ist und
  • Fig. 2 eine Ausführungsform mit einem aus der Klemmfeder ausgescherten Lappen zur Verrastung der Klemmfeder.
Show it:
  • Fig. 1 shows an embodiment of the clamping spring, in which a slot or a recess in the other end is provided for locking one end and
  • Fig. 2 shows an embodiment with a tab sheared from the clamping spring for locking the clamping spring.

In Fig. 1 ist in einer Gehäuseausnehmung 1 eines Gerätegehäuses 2, das beispielsweise das Gehäuse eines elektromagnetischen Schaltgerätes sein kann, eine Klemmfeder 3 an Gehäusevorsprüngen 4 eingerastet. Das eine Ende 5 der blattförmigen Klemmfeder dient zum Klemmen des Leiters 6, der in Richtung des Pfeiles 7 einschiebbar ist. Die Stromweiterleitung erfolgt über eine Geräteanschlußschiene 8, die in der Gehäuseausnehmung 1 eingelegt ist. Das andere Ende 9 der Klemmfeder 3 liegt mit einem abgewinkelten Ende an der Geräteanschlußschiene 8 mehr oder weniger parallel zum einen Ende 5 an und besitzt im Endbereich eine schlitzförmige Aussparung 10, in die das Ende 5 im gespannten Zustand eindrückbar und verrastbar ist. Zum Spannen und Verrasten des einen Endes 5 mit der schlitzförmigen Aussparung 10 kann eine Schraubenzieherklinge 11 in eine dem Klemmfederende 5 gegenüberliegende Gehäuseöffnung 12 eingeführt werden, die mit einer Durchbrechung 13 in der Geräteanschlußschiene fluchtet. Hierbei wird das freie Ende 5 der Klemmfeder 3 gespannt und schnappt hernach in die Aussparung 10 ein. Der Leiter 6 kann eingelegt werden und durch Einführen des Schraubenziehers in die Gehäuseöffnung 14, die mit der Durchbrechung 15 in der Geräteanschlußschiene 8 fluchtet, wird das andere Ende 9 der Klemmfeder verschwenkt, d.h. das eine Ende 5 der Klemmfeder wird freigegeben, so daß dieses den Leiter 6 gegen die Geräteanschlußschiene 8 drückt und zwar - wie oben erwähnt - mit dem Effekt der Selbsthemmung. Zum Lösen des Leiters braucht lediglich der Schraubenzieher wieder in die Gehäuseöffnung 12 eingeschoben zu werden. Über den Leiter 6 wird das eine Ende 5 der Klemmfeder 3 wieder zusammengebogen und verrastet in der schlitzförmigen Aussparung 10, so daß der Leiter 6 frei entnommen werden kann. Durch eine Abstützung 18 (am Gehäuse) wird eine plastische Verformung und Überdehnung der Feder verhindert.In Fig. 1, a clamping spring 3 is latched to housing projections 4 in a housing recess 1 of a device housing 2, which can be, for example, the housing of an electromagnetic switching device. One end 5 of the leaf-shaped clamping spring is used to clamp the conductor 6, which can be inserted in the direction of arrow 7. The current is passed on via a device connecting rail 8 which is inserted in the housing recess 1. The other end 9 of the clamping spring 3 lies with an angled end on the device connection rail 8 more or less parallel to the one end 5 and has in the end region a slot-shaped recess 10, into which the end 5 can be pressed and locked in the tensioned state. For tensioning and latching one end 5 with the slot-shaped recess 10, a screwdriver blade 11 can be inserted into the clamping spring end 5 opposite housing opening 12 are inserted, which is aligned with an opening 13 in the device connection rail. Here, the free end 5 of the clamping spring 3 is tensioned and then snaps into the recess 10. The conductor 6 can be inserted and by inserting the screwdriver into the housing opening 14, which is aligned with the opening 15 in the device connection rail 8, the other end 9 of the clamping spring is pivoted, ie one end 5 of the clamping spring is released so that this Conductor 6 presses against the device connection rail 8 - as mentioned above - with the effect of self-locking. To release the conductor, only the screwdriver needs to be pushed back into the housing opening 12. One end 5 of the clamping spring 3 is bent back over the conductor 6 and locked in the slot-shaped recess 10, so that the conductor 6 can be removed freely. A support 18 (on the housing) prevents plastic deformation and overextension of the spring.

Die Ausführungsform nach Fig. 2 unterscheidet sich von der nach Fig. 1 dadurch, daß die Geräteanschlußschiene als Metallkäfig16 ausgebildet ist, so daß die von der Klemmfeder aufgebrachten Kräfte nicht auf Kunststoffteile einwirken. Weiterhin ist die schlitzförmige Aussparung 10 durch einen ausgescherten Lappen 17 ersetzt und das andere Ende 9 ist abgewinkelt, um eine bessere Auflagefläche für die Schraubenzieherklinge 11 zu bieten. Die Gehäusevorsprünge 4 sind hier im Metallkäfig 16 eingeprägt.The embodiment of FIG. 2 differs from that of FIG. 1 in that the device connection rail is designed as a metal cage 16, so that the forces applied by the clamping spring do not act on plastic parts. Furthermore, the slot-shaped recess 10 is replaced by a sheared tab 17 and the other end 9 is angled to provide a better contact surface for the screwdriver blade 11. The housing projections 4 are stamped in the metal cage 16 here.
