Description

Die Erfindung betrifft eine Klemme für den Anschluss eines elektrischen Leiters, die in einem einen Vorrichtungsrahmen bildenden Gehäuse eine im montierten Zustand das Leiterende einklemmende Biegefeder und ein schwenkbar gelagertes Betätigungsorgan mit einer Kurvenscheibe zum verstärkten Spannen der Feder und damit Öffnen der Klemme aufweist, wobei das Betätigungsorgan seinerseits durch einen Endabschnitt eines als Hebel zu benutzenden langgestreckten Werkzeugs, insbesondere eines Schraubendrehers, zu betätigen ist, für den es eine Aufnahme aufweist.The invention relates to a terminal for the connection of an electrical conductor having in a device frame forming a housing in the assembled state, the conductor end bending spring and a pivotally mounted actuator with a cam for increased tensioning of the spring and thus opening the terminal, wherein the actuator in turn, by an end portion of an elongated tool to be used as a lever, in particular a screwdriver, to operate, for which it has a receptacle.

Eine solche Klemme ist aus der DE 195 29 028 A1 bekannt. Das Betätigungsorgan dieser Klemme hat in der Öffnungsstellung der Klemme eine im Prinzip stabile Endlage dadurch, dass eine flache Delle in der Kurvenscheibe auf einer flachen Aufwölbung der Biegefeder liegt. Der Monteur hat dann beide Hände für seine Arbeit frei. Bei versehentlichem Anstoßen an dem Betätigungsorgan oder dem Werkzeug kann das Betätigungsorgan allerdings aus der an sich stabilen Endlage gebracht werden und zurückschnappen.Such a clamp is out of the DE 195 29 028 A1 known. The actuator of this terminal has in the open position of the terminal in principle a stable end position in that a flat dent in the cam on a flat curvature of the spiral spring is located. The fitter then has both hands free for his work. In case of accidental abutment of the actuator or the tool, however, the actuator can be brought out of the per se stable end position and snap back.

Der Erfindung liegt die Aufgabe zugrunde, die Stabilität des Betätigungsorgans in der Öffnungsstellung der Klemme zu erhöhen.The invention has for its object to increase the stability of the actuator in the open position of the terminal.

Gemäss der Erfindung wird dieser Zweck erfüllt, indem in der Öffnungsstellung der Klemme das Ende des Werkzeugs weiter durchschiebbar ist bis zu einem Gehäuseteil, durch das das Werkzeug gegen Rückschwenken gesperrt und damit das Betätigungsorgan in der Öffnungsstellung gehalten oder gesichert ist.According to the invention, this purpose is fulfilled by the end of the tool in the open position of the clamp is further pushed through to a housing part, locked by the tool against pivoting back and thus the actuator is held or secured in the open position.

Der sperrende Zusammengriff, beispielsweise ein Eingriff der Schraubendreherspitze in eine in dem Gehäuse ausgebildete Tasche, kann hier eine unvergleichlich größere Tiefe und damit Sicherheit haben als der erwähnte Eingriff einer flachen Aufwölbung in eine flache Delle.
Es braucht nicht einmal ein Totpunkt der Kurvenscheibe auf der Feder erreicht zu werden. Durch die erfindungsgemäße Sperrung wird das Betätigungsorgan trotzdem gehalten.
Liegt die Kurvenscheibe mit einem Totpunkt auf der Feder, so wird durch die Sperrung das Betätigungsorgan in der Öffnungsstellung gesichert.The blocking engagement, such as engagement of the screwdriver tip into a pocket formed in the housing, can here have an incomparably greater depth and thus safety than the mentioned engagement of a flat bulge in a shallow dent.
It does not even need a dead center of the cam to be reached on the spring. By blocking the invention, the actuator is still held.
If the cam lies with a dead center on the spring, then the actuator is secured in the open position by the blocking.

Vorzugsweise ist die Aufnahme für den Endabschnitt des Werkzeugs eine durchgehende Ausnehmung in dem Betätigungsorgan und das Werkzeug über die Aufnahme hinaus weiter vorschiebbar; das genannte Gehäuseteil liegt dann etwa in der Verlängerung der Aufnahme. Im Falle der Tasche liegt diese im wesentlichen genau in der Verlängerung der Aufnahme und eine Wand der Tasche bildet das sperrende Gehäuseteil.
Grundsätzlich wären aber auch andere Anordnungen der Sperrung möglich. Beispielsweise könnte das Werkzeug am Ende der Aufnahme seitlich frei liegen und nach der Seite hin einen sperrenden Zusammengriff erhalten o.a.m..Preferably, the receptacle for the end portion of the tool is a continuous recess in the actuator and the tool beyond the receptacle further advanceable; said housing part is then approximately in the extension of the recording. In the case of the bag, this is located substantially exactly in the extension of the recording and a wall of the bag forms the locking housing part.
In principle, however, other arrangements of blocking would be possible. For example, the tool could be at the end of the recording laterally exposed and received to the side of a blocking combination oam.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist das Betätigungsorgan in ein Aufnahmeteil für den Endabschnitt des Werkzeugs und die, an das Aufnahmeteil angeformte, Kurvenscheibe gegliedert.
Damit ergibt sich ein geringer Platzbedarf und Materialverbrauch bei klarer Trennung zwischen einem für das Werkzeug beanspruchten und einem für die elektrische Klemmung zur Verfügung stehenden Raum.According to a further advantageous embodiment of the invention, the actuating member is articulated in a receiving part for the end portion of the tool and, integrally formed on the receiving part, cam.
This results in a small footprint and material consumption with a clear separation between a claimed for the tool and a space available for the electrical clamping space.

Eine weitere vorteilhafte Ausgestaltung ist gekennzeichnet durch eine auf der Achse des schwenkbaren Betätigungsorgans angeordnete, im Rückstellsinn auf das Betätigungsorgan wirkende Schenkelfeder oder eine in der Ausgangsstellung des Betätigungsorgans in eine Delle am Umfang des Betätigungsorgans, vorzugsweise der Kurvenscheibe, fassende Biegefeder.
Damit wird das Betätigungsorgan auch dann in seiner Ausgangsstellung gehalten, wenn ein Leiterende eingeklemmt ist und damit die das Leiterende einklemmende Biegefeder keine Rückstellkraft auf das Betätigungsorgan ausüben kann. Irratation durch ein loses Teil wird vermieden. Das Betätigungsorgan kann nicht durch falsche Stellung beim Aufsetzen der üblichen Abdeckung stören.A further advantageous embodiment is characterized by a arranged on the axis of the pivotable actuator, acting in the reset direction on the actuator leg spring or in the starting position of the actuator in a dent on the circumference of the actuator, preferably the cam, summarizing spiral spring.
Thus, the actuator is held in its initial position, even if a conductor end is clamped and thus the spring end clamped bending spring can not exert any restoring force on the actuator. Irratation by a loose part is avoided. The actuator can not interfere with incorrect position when placing the usual cover.

In einer Variante der Erfindung weist das Gehäuse statt eines schwenkbar gelagerten Betätigungsorgans mit einer Kurvenscheibe ein Gegenlager für das Ende des Werkzeugs als Hebeldrehpunkt und ein Betätigungsorgan in Form eines in dem Gehäuse geführtes Druckstücks auf, das durch Andrücken des an das genannte Ende anschließenden Abschnitts des Werkzeugs unter Verbiegung der Feder verschiebbar ist; wiederum ist dabei in der Öffnungsstellung der Klemme das Ende des Werkzeugs weiter vorschiebbar bis zu einem Gehäuseteil, durch das das Werkzeug gegen Rückschwenken gesperrt und damit das Betätigungsorgan in der Öffnungsstellung gehalten ist.In a variant of the invention, the housing instead of a pivotally mounted actuating member with a cam on an abutment for the end of the tool as a fulcrum and an actuator in the form of a guided in the housing pressure piece, which by pressing the adjoining said end portion of the tool is displaceable under bending of the spring; in turn, in the open position of the clamp, the end of the tool is further advanceable up to a housing part, by which the tool is locked against pivoting back and thus the actuator is held in the open position.

Für beide Varianten ist insbesondere die an sich bekannte Ausbildung der Klemme vorgesehen, dass ein Leiterteil, mit dem das genannte Leiterende in dem Klemmengehäuse zu verbinden ist, mit der Biegefeder zusammengebaut ist in der Weise, dass die Biegefeder mit einem Schenkel auf dem Leiterteil liegt, mit einem Biegeschenkel von ihm abgebogen und dann noch einmal in Richtung auf das Ende des ersteren Schenkels und über dieses hinaus in einen dritten, leicht bogenförmigen Schenkel umgebogen ist, in dem sich ein rechteckiger Ausschnitt befindet, durch den das Leiterteil ragt, wobei die untere Kante des Ausschnitts in Richtung auf das Leiterteil gezogen ist und das Leiterende von unten an das Leiterteil presst.For both variants, in particular the known per se training of the terminal is provided that a conductor part, with which said conductor end is to be connected in the terminal housing is assembled with the spiral spring in such a way that the bending spring is located with a leg on the ladder part, bent with a bending leg of him and then bent again in the direction of the end of the former leg and beyond this in a third, slightly curved leg, in which there is a rectangular cutout, through which the ladder part protrudes, the lower edge the section is pulled in the direction of the ladder part and presses the conductor end of the bottom of the ladder part.

In einem einen Vorrichtungsrahmen 1 bildenden Gehäuse 1 - siehe zunächst Fig. 7 - ist ein Leiterteil 2 gehalten, das an seinem Ende 3 in einer Gesamtvorrichtung, z.B. einem Leitungsschutzschalter, weiterverbunden ist.
Das Leiterteil 2 ist mit einer im wesentlichen dreischenkligen Biegefeder 4 kombiniert. Ein Schenkel 5 liegt auf dem Leiterteil 2. Ein Biegeschenkel 6 ist von ihm abgebogen. Schließlich ist von diesem ein dritter, leicht bogenförmiger Schenkel 7 abgebogen nach dem Ende des ersteren Schenkels hin. In dem bogenförmigen Schenkel befindet sich ein rechteckiger Ausschnitt 8. Durch diesen ragt, das gekröpfte, andere Ende 9 des Leiterteils 2.In a housing frame 1 forming a device frame 1 - see first Fig. 7 - Is a conductor part 2 is held, which is further connected at its end 3 in an overall device, such as a circuit breaker.
The ladder part 2 is combined with a substantially three-legged bending spring 4. A leg 5 is located on the ladder part 2. A bending leg 6 is bent from him. Finally, this is a third, slightly curved leg 7 bent towards the end of the former leg out. In the arcuate leg is a rectangular section 8. Through this protrudes, the cranked, other end 9 of the ladder part. 2

In den Raum 10 unter dem Leiterteil 2 führt eine Einführung 11 für das anzuschließende Leiterende. Das abisolierte Ende wird bei niedergedrückter Biegefeder 4 durch den Ausschnitt 8 hindurch gesteckt. Ist die Biegefeder freigegeben, so drückt die Unterkante des Ausschnitts 8 das Leiterende von unten gegen das Leiterteil 2.In the space 10 below the ladder part 2 performs an introduction 11 for the conductor end to be connected. The stripped end is inserted through the cutout 8 when the bending spring 4 is depressed. If the bending spring is released, the lower edge of the cutout 8 presses the conductor end from below against the conductor part 2.

Zum Niederdrücken und Freigeben der Biegefeder 4 dient ein Betätigungsorgan 12.
Das Betätigungsorgan 12 ist schwenkbar gelagert auf einer durch das Gehäuse 1 hindurch gesteckten, z.B. an den Außenseiten der Gehäusewände vernieteten Achse. Es besteht aus einem Aufnahmeteil 14 mit einer Aufnahme 15 für den Endabschnitt 16 eines Schraubendrehers 17 und einer seitlich an das Aufnahmeteil 14 angeformten Kurvenscheibe 18. Die Kurvenscheibe 18 liegt über der Biegefeder 4.
Durch eine auf der anderen Seite des Aufnahmeteils 14 in dieses eingelassene Schenkelfeder 19 wird das Aufnahmeteil in seine in Fig. 1 bis 3 gezeigte Ausgangsstellung gedrückt.For depressing and releasing the bending spring 4 is an actuator 12th
The actuating member 12 is pivotally mounted on a through the housing 1 inserted through, for example, riveted to the outer sides of the housing walls axis. It consists of a receiving part 14 with a receptacle 15 for the end portion 16 of a screwdriver 17 and a laterally integrally formed on the receiving part 14 cam 18. The cam 18 is located above the spiral spring 4th
By a on the other side of the receiving part 14 inserted into this leg spring 19, the receiving part in his in Fig. 1 to 3 pressed initial position shown.

Zum Öffnen der Klemme wird unter Verwendung des in die Aufnahme 15 eingesteckten Schraubendrehers 17 als Hebel, ersatzweise mit einem an einem Überstand 20 des Aufnahmeteils 14 ansetzenden, in Fig. 7 bei 21 angedeuteten Finger, das Aufnahmeteil 14 verschwenkt. Dabei gleitet die Kurvenscheibe 18 über die Biegefeder 4 und drückt sie nieder. Ein aus dem Gehäuse 1 herausragender Stutzen 22, der etwa auf einem Halbkreis von der Biegefeder 4 umschlossen ist, hält dabei den Schenkel 5 der Biegefeder, der sich sonst aufwölben würde, in Anlage an den Leiterteil 2.To open the clamp is using the plugged into the receptacle 15 screwdriver 17 as a lever, alternatively with an attaching to a projection 20 of the receiving part 14, in Fig. 7 at 21 indicated fingers, the receiving part 14 pivots. The cam 18 slides over the spiral spring 4 and presses it down. A protruding from the housing 1 nozzle 22, which is enclosed on a semicircle of the spiral spring 4, while holding the leg 5 of the spiral spring, which would otherwise bulge, in contact with the conductor part. 2

Um die Biegefeder in der niedergedrückten Stellung zu sichern, kann in dieser Stellung des Betätigungsorgans 12 der Schraubendreher 17 durch die Aufnahme 15 weiter hindurchgeschoben und mit seinem abgeflachten oder zugespitzten Ende 23 in eine Tasche 24 des Vorrichtungsrahmens 1 gesteckt werden. Die Seitenwand 25 der Tasche 24 sperrt nun gegen Rückschwenken.In order to secure the spiral spring in the depressed position, in this position of the actuating member 12 of the screwdriver 17 through the receptacle 15 pushed further and with its flattened or pointed end 23 in a pocket 24 of the device frame 1 are inserted. The side wall 25 of the pocket 24 now locks against pivoting back.

Für die Rückbewegung des Betätigungsorgans 12 wird der Schraubenzieher wieder aus der Tasche 24 herausgezogen. Nach Belieben kann er auch ganz aus der Aufnahme 15 herausgezogen und das Betätigungsorgan (12) von Hand zurückgestellt werden.For the return movement of the actuator 12, the screwdriver is pulled out of the pocket 24 again. At will, he can also be completely pulled out of the receptacle 15 and the actuator (12) are reset by hand.

Steckt jetzt ein Leiterende in dem Ausschnitt 8, so kehrt die Biegefeder 4 nicht in ihre Ausgangsstellung zurück, in der sie auch die Kurvenscheibe 18 und damit das Betätigungsorgan 12 im wesentlichen in der Ausgangsstellung halten könnte.
Diese Aufgabe erfüllt stattdessen die Schenkelfeder 19.Now puts a conductor end in the cutout 8, the bending spring 4 does not return to its original position in which they could hold the cam 18 and thus the actuator 12 substantially in the starting position.
This task fulfills the leg spring 19 instead.

Im übrigen lässt Fig. 7 Vorkehrungen zum Ansetzen eines in Fig. 7 abgenommenen, jedoch in Fig. 1 erscheinenden Wandteils 26 erkennen, nämlich einen Hohlstutzen 27 und zwei Vertiefungen 28 zum gegenseitigen Eingriff mit einer Vertiefung bzw. Hohlstutzen des Wandteils 26.For the rest leaves Fig. 7 Arrangements for preparing an in Fig. 7 taken off, but in Fig. 1 apparent wall portion 26, namely a hollow pipe 27 and two recesses 28 for mutual engagement with a recess or hollow socket of the wall portion 26th

In Fig. 8 ist statt der Schenkelfeder 19 eine Biegefeder 29 vorgesehen, die in der Gebrauchsstellung der Klemme in eine Delle 35 an der, hier mit 30 bezeichneten, Kurvenscheibe greift. Die erstgenannte Biegefeder ist mit 31, das Betätigungsorgan ist mit 32 und das eingesetzte Leitungsende ist mit 33 bezeichnet. Durch Verschwenken des Betätigungsorgans 32 drückt die Kurvenscheibe 30 auch hier die Biegefeder nieder. Die Delle 35 bewegt sich dabei über die Biegefeder 39.In Fig. 8 a bending spring 29 is provided instead of the leg spring 19, which engages in the position of use of the terminal in a dent 35 at the, designated here by 30, cam. The first-mentioned bending spring is at 31, the actuator is 32 and the line end used is designated 33. By pivoting the actuator 32, the cam 30 presses down here also the bending spring. The dent 35 moves over the bending spring 39.

Bei der in Fig. 9 dargestellten anderen Variante ist das Betätigungselement verwirklicht durch ein Druckstück 36.At the in Fig. 9 illustrated another variant, the actuating element is realized by a pressure piece 36th

Dargestellt ist eine Vierfach-Klemme im wesentlichen von einer Seite und an der Sichtseite aufgebrochen.Shown is a quadruple clamp broken substantially from one side and on the visible side.

Zu erkennen sind in gegenüberliegender Anordnung zwei Einführungen 37, zwei mit der Biegefeder 4 vier gleiche Biegefedern 38, und zwei dem Stutzen 22 entsprechende Stutzen 39. Zwei Leiterteile 40 haben die Funktion des Leiterteils 2, sind aber anders gestaltet.Evident are in opposite arrangement two introductions 37, two with the spiral spring 4 four equal spiral springs 38, and two nozzles 22 corresponding nozzle 39. Two conductor parts 40 have the function of the conductor part 2, but are designed differently.

Die Druckstücke 36 sind in dem mit 41 bezeichneten Gehäuse geführt. Sie können mittels eines Schraubendrehers 42 niedergedrückt werden und so die Biegefeder 38 spannen. Eingeführt wird der Schraubendreher in der Stellung, wie in Fig. 9 links für die linke Klemme gezeichnet. Er wird dann verschwenkt, wobei er sich an einem bei 43 angedeuteten Gegenlager abstützt und auf das Druckstück drückt, wie in Fig. 9 rechts für die rechte Klemme dargestellt. Diese Darstellung zeigt außerdem bereits den nächsten Schritt: Bei der niedergedrückten Stellung der Biegefeder 38 findet das Ende des Schraubendrehers 42 eine Tasche, in die hinein der Schraubendreher weiter vorgeschoben werden. Er ist dann durch die eine Taschenwand 45 gegen Rückschwenken gehalten und hält so die Klemme in der Öffnungsstellung.
Zum Schließen der Klemme wird der Schraubendreher 42 herausgezogen.The pressure pieces 36 are guided in the housing designated 41. They can be depressed by means of a screwdriver 42 and thus tension the bending spring 38. The screwdriver is inserted in the position as in Fig. 9 drawn left for the left clamp. He is then pivoted, where he is supported on an abutment indicated at 43 and presses on the pressure piece, as in Fig. 9 shown right for the right clamp. This illustration also shows already the next step: In the depressed position of the bending spring 38, the end of the screwdriver 42 finds a pocket into which the screwdriver is further advanced. He is then held by the one pocket wall 45 against pivoting back, thus keeping the clamp in the open position.
To close the clamp, the screwdriver 42 is pulled out.
