Description

Schraubenlose Anschluß- oder Verbindungsklemme fürScrewless terminal or connector for

elektfische Leiter 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 unter Verwendung eines sich einerseits am Gehäuse abstützenden und andererseits die Klemmfeder gespannt haltenden betriebsmäßig klemmkraftfreien Spannorganes, das in zwei definierte Endlagen und von der Außenseite von der verrasteten gespannten in die entspannte Lage und umgekehrt verstellbar ist.Electric conductors The invention relates to a screwless one Terminal or connecting terminal for electrical conductors with a front insertion of the conductor to be tensioned and, after its insertion, the conductor to be clamped, in one Housing arranged clamping spring using a one hand on the housing supporting and, on the other hand, holding the clamping spring tensioned, operationally free of clamping force Clamping element that is locked in two defined end positions and from the outside of the tensioned to the relaxed position and vice versa is adjustable.

Bei einer bekannten Klemme der obengenannten Art (DE-OS 30 44 134) ist zwar ein stößelähnliches Spannorgan mit einem Schraubendreherschlitz vorgesehen, dessen Schlitzstellung den Zustand der Klemme anzeigt. Jedoch muß hier zum Offenen der Klemme verhältnismäßig großer Druck auf den Stößel mit dem Schraubendreher ausgeführt werden, was zumindest eines besonderen Hinweises zur Bedienung der Klemme bedarf.In a known clamp of the type mentioned above (DE-OS 30 44 134) a plunger-like clamping element with a screwdriver slot is provided, the slot position of which indicates the state of the clamp. However, here must be open the clamp carried out relatively large pressure on the plunger with the screwdriver which requires at least a special note on the operation of the terminal.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Klemme der obengenannten Art dahingehend zu verbessern, daß sie nach Art einer Schraubklemme bedienbar ist. Dies wird auf einfache Weise praktisch ohne weiteren Aufwand dadurch erreicht, daß das Spannorgan schraubenlinienförmig ansteigende Laufflächen über einen Verdrehungsbereich von ca.The invention is therefore based on the object of a clamp of the above Kind to the effect that it can be operated in the manner of a screw terminal. This is achieved in a simple manner, practically without further effort, in that the tensioning element helically rising running surfaces over a twisting area from approx.

900 aufweist, die sich an entaprechend geformten Rippen des Klemmgehäuses zur Oeffnung der Klemme derart abstützen, daß bei der vorbestimmten Winkeldrehung der Spannhub der Klemmfeder erreicht ist.900 has, which are attached to correspondingly shaped ribs of the terminal housing to open the clamp so that at the predetermined angular rotation the tensioning stroke of the clamping spring has been reached.

Um auch die bei Schraubklemmen gewohnte Drehrichtung für Spannorgan beizubehalten ist es vorteilhaft, wenn dem Spannvorgang der Klemmfeder die Links- und der Entrastung die Rechtsdrehung des Spannorganes zugeordnet ist. Auf zusätzliche Mittel zur Verrastung des Spannorganes innerhalb des Gehäuses kann verzichtet werden, wenn die Verrastung durch Anpassung des der Klemmfeder zugewandten Endes des Spannorganes an die Kontur der Klemmfeder in gespanntem Zustand erfolgt.This also applies to the direction of rotation for the clamping device that is familiar with screw terminals to maintain it is advantageous if the tensioning process of the clamping spring the left and the unlatching is assigned to the clockwise rotation of the tensioning element. On additional Means for locking the clamping element within the housing can be dispensed with, if the latching is achieved by adapting the end of the tensioning element facing the clamping spring takes place on the contour of the clamping spring in the tensioned state.

Anhand der Zeichnung wird ein Ausführungsbeispiel gemäß der Erfindung beschrieben und die Wirkungsweise näher erläutert.An exemplary embodiment according to the invention is illustrated with the aid of the drawing described and the mode of operation explained in more detail.

Es zeigt: Fig. 1 eine Schnittdarstellung durch die erfindungsgemäße Klemme Fig. 2 eine Detaildarstellung im Bereich der Verrastung des Spannorganes mit der Klemmfeder, Fig. 3 eine Möglichkeit der Drehwinkel-Begrenzung.It shows: FIG. 1 a sectional illustration through the inventive Terminal Fig. 2 is a detailed representation in the area of the latching of the clamping member with the clamping spring, Fig. 3, a possibility of limiting the angle of rotation.

In Fig. 1 ist in einer oeffnung 1 eines Gerätegehäuses 2, das beispielsweise das Gehäuse eines elektromagnetischen Schaltgerätes sein kann, eine an sich bekannte Federklemme 3 untergebracht. Der Anschlußleiter 4 der Federklemme 3 kann beispielsweise das feste Kontaktstück eines elektromagnetischen Schaltgerätes bilden. Die haarnadelförmig gebogene Blattfeder 5 der Federklemme 3 übergreift mit einem Durchbruch 6 das abgebogene Ende 7 des Anschlußleiters 4 und bildet gleichzeitig die Eintrittsöffnung für das abisolierte Ende 8 des Leiters 9. In der oeffnung 1 ist weiterhin das stößelförmige Spannorgan 10 geführt.In Fig. 1 is in an opening 1 of a device housing 2, for example the housing of an electromagnetic switching device can be a known one Spring clip 3 housed. The connecting conductor 4 of the spring terminal 3 can, for example form the fixed contact piece of an electromagnetic switching device. The hairpin-shaped curved leaf spring 5 of the spring clip 3 engages with an opening 6 over the bent End 7 of the connecting conductor 4 and at the same time forms the inlet opening for the stripped end 8 of the conductor 9. In the opening 1 is still the pestle-shaped Clamping member 10 out.

Gegenüberliegende, schraubenlinienförmig ansteigende Laufflächen 11 des Spannorgans 10 stützen sich an entsprechend geformten Rippen 12 des Gehäuses 2 ab und zwar im gespannten, d.h. im geöffneten Zustand der Federklemme 3. Das der Klemmfeder zugewandte Ende 13 des Spannorgans 10 ist mit einer Rinne 14 ausgestattet, die sich mit der Kontur der Blattfeder 5 an der Berührungsstelle deckt, so daß das Spannorgan 10 mit der Federklemme 3 im geöffneten Zustand der Klemme verrastet. Der Drehwinkel des Spannorgans 10 wird z.B. durch angeformte Ecken 17 begrenzt, die sich nach dem Durchlaufen der vorbestimmten Drehung am Gerätegehäuse 2 abstützen und Weiterdrehung verhindern.Opposing, helically rising running surfaces 11 of the clamping member 10 are supported on correspondingly shaped ribs 12 of the housing 2 in the tensioned, i.e. in the open state of the spring clamp 3. The der Clamping spring facing end 13 of tensioning member 10 is with a gutter 14 equipped, which is with the contour of the leaf spring 5 at the point of contact covers, so that the clamping member 10 with the spring clamp 3 in the open state of the Clamp locked. The angle of rotation of the tensioning member 10 is e.g. 17 limited, which is after passing through the predetermined rotation on the device housing 2 and prevent further rotation.

Zur Funktion der Klemme ist folgendes auszuführen: Wird der Leiter 9 mit dem abisolierten Ende 8 in den Durchbruch 6 eingeführt und das Spannorgan 10 durch Rechtsdrehung durch Einführen des Schraubendrehers in den Schraubendreherschlitz 15 über die Laufflächen 11 geführt an den Rippen 12 außer Eingriff mit der Federklemme 3 gebracht, d.h. der Bereich der Rinne 14 liegt höchstens lose an der Blattfeder 5 an, spannt diese jedoch nicht mehr. Die Spannung der Blattfeder 5 wird über die Kante 16 des Durchbruches 6 auf das abisolierte Ende 8 des Leiters 9 übertragen und drückt diesen gegen den Anschlußleiter 4, um mmit diesem kontaktiert zu werden. Zum Lösen der Klemme wird wie üblich der Schraubendreher links gedreht, d.h.The following is to be carried out for the function of the terminal: Will the conductor 9 with the stripped end 8 inserted into the opening 6 and the clamping member 10 by turning to the right by inserting the screwdriver into the screwdriver slot 15 guided over the running surfaces 11 on the ribs 12 out of engagement with the spring clip 3 brought, i.e. the area of the channel 14 is at most loosely on the leaf spring 5, but no longer tense it. The tension of the leaf spring 5 is on the Transfer the edge 16 of the opening 6 to the stripped end 8 of the conductor 9 and presses it against the connecting conductor 4 in order to be contacted with it. To loosen the clamp, turn the screwdriver to the left as usual, i.e.

die Laufflächen 11 kommen wieder unter Druck zur Anlage an den Rippen 12. Die Blattfeder 5 wird gespannt, die Verrastung in der geöffneten Stellung erfolgt über die Rinne 14 am gerundeten Teil der Blattfeder 5. Der Leiter kann ohne Schwierigkeiten herausgezogen werden. Eine derartige Klemme ist auch ohne weiteres für flexible Leiter geeignet. Die Bedienungsweise ist der der Schraubklemme praktisch gleich. Der besondere Vorteil liegt jedoch hierin, daß lediglich ein Verdrehungswinkel von ca.the running surfaces 11 come under pressure to rest on the ribs 12. The leaf spring 5 is tensioned and it is locked in the open position over the channel 14 on the rounded part of the leaf spring 5. The head can without difficulty be pulled out. Such a clamp is also easily flexible Head suitable. The operation is practically the same as that of the screw terminal. The particular advantage, however, is that only a twist angle of approx.

900 erforderlich ist. 900 is required.
