Schraubenlose KlemmeScrewless clamp
Die Erfindung bezieht sich auf eine schraubenlose Klemme, die bei Geraten der Installationstechnik einsetzbar ist, also beispielsweise bei Leitungsschutzschaltern, Fehlerstromschutzschaltern, Reihenklemmen oder Steckdosen. Die Klemme arbeitet im Prinzip mit einer losbaren Klemmfeder, die einen anzuschließenden Leiter unter ihrer Federkraft mit einer Stromschiene m Verbindung bringt, im einzelnen nach Gattungsbegriff von Anspruch 1.The invention relates to a screwless terminal which can be used in devices for installation technology, for example in line circuit breakers, residual current circuit breakers, terminal blocks or sockets. The terminal works in principle with a releasable clamping spring, which connects a conductor to be connected under its spring force to a busbar m, in detail according to the preamble of claim 1.
Derartige schraubenlose Klemmen bezeichnet man auch als Ka- figklemmen bzw. als „Cage Clamp* . Zum Offnen einer Kafigklem- me wird im allgemeinen mit einem geeigneten Gegenstand, beispielsweise einem Schraubendreher, direkt die spannungsführende Klemmfeder niedergedruckt. Aus Sicherheitsgründen ist ein isoliertes Werkzeug erforderlich, um aus einer schrauben- losen Klemme einen angeschlossenen Leiter wieder abziehen zu können. Zum Anschließen mehrerer potentialgetrennter Adern einer Leitung wird m der Regel jede Ader m einem eigenen Anschlußvorgang geklemmt und ggf. auch wieder gelost. Um das Betatigen, insbesondere Offnen, einer schraubenlosen Klemme für mehrere potentialgetrennte Adern gleichzeitig zu ermögli¬ chen, sind auch schon kammformige Einsteckteile vorgesehen worden. Hierbei ist es jedoch erforderlich, daß die Betati- gungsseite großraumig zugänglich ist.Such screwless clamps are also called cage clamps or “cage clamps”. To open a cage clamp, the live clamping spring is generally directly pressed down with a suitable object, for example a screwdriver. For safety reasons, an insulated tool is required in order to be able to remove a connected conductor from a screwless terminal. To connect several electrically isolated wires of a line, each wire is usually m clamped in its own connection process and, if necessary, detached again. To the actuation of, especially opening, a screwless terminal for several potentially isolated conductors chen while ermögli ¬, even kammformige male parts have been provided. Here, however, it is necessary that the actuation side is accessible over a large area.
Der Erfindung liegt die Aufgabe zugrunde, eine schraubenlose Klemme zu entwickeln, die bequemer zu handhaben ist und die einfach zu bedienende mehrpolige Klemmen ermöglicht.The invention has for its object to develop a screwless terminal that is more convenient to use and that allows easy-to-use multi-pole terminals.
Die Losung der geschilderten Aufgabe erfolgt nach der Erfin- düng durch eine schraubenlose Klemme nach Anspruch 1. Hier¬ nach steht mit der Klemmfeder oder mit einem Losedruckstuck in deren Loserichtung ein aufgleitender keilförmiger Losekor- per m Wirkverbindung. Hierdurch erübrigt sich ein gesondertes Werkzeug, wie ein Schraubendreher, um angeschlossene Leiter zu losen und darüber hinaus wird das Einfuhren von Leitern erleichtert, so daß sich auch Litzenleiter anschließen lassen. Der Losekorper laßt sich m einfacher Weise aus Iso- liermaterial fertigen, so daß Sicherheit gewährleistet ist. Ein Losedruckstuck kann hinsichtlich guter Gleiteigenschaft ausgewählt sein.According to the invention, the described task is solved by means of a screwless clamp according to claim 1. Here, ¬ is a sliding wedge-shaped loose element with the clamping spring or with a loose piece in its loose direction. per m active connection. This eliminates the need for a separate tool, such as a screwdriver, to loosen connected conductors and also facilitates the import of conductors so that stranded conductors can also be connected. The loose body can be manufactured in a simple manner from insulating material, so that safety is guaranteed. A loose piece can be selected for good sliding properties.
Nach einer Weiterbildung kann der aufgleitende Losekorper bzw. ein Losedruckstuck als zwei gegeneinander verschiebliche Keile ausgeführt sein. Durch geeignete Werkstoffwahl ist es leicht möglich, gute Gleiteigenschaften zu erzielen. Auf die Klemmfeder wird hierbei von einem ruhenden Teil Druck ausge- übt, so daß Verkantungen mit der Klemmfeder ausgeschlossen sind.According to a further development, the sliding loose body or a loose pressure piece can be designed as two wedges which can be moved relative to one another. With a suitable choice of material, it is easily possible to achieve good sliding properties. Pressure is exerted on the clamping spring by a stationary part, so that canting with the clamping spring is excluded.
Bei einer Anreihung von schraubenlosen Klemmen kann mit einem sagezahnformigen Losekorper über ein sagezahnformiges Druck- stuck eine gleichzeitige Aufspreizung der Klemmfedern der angereihten Klemmen bewirkt werden.In the case of a series of screwless clamps, a sawtooth-shaped loose body can be used to spread the clamp springs of the adjacent clamps at the same time via a sawtooth-shaped pressure piece.
Wenn beim Losekorper und beim Lösedruckstück im Endbereich ihrer aufspreizenden Verschiebungsstrecke eine Abflachung vorgesehen ist, kann man in einfacher Weise eine Offenstellung der Klemme erzielen. Es ist dann sichergestellt, daß die Klemmfedern die gegeneinander verschieblichen Teile, also Losekorper und Losedruckstuck nicht zuruckgleiten lassen können.If a flattening is provided in the loose body and in the release pressure piece in the end region of their spreading displacement distance, an open position of the clamp can be achieved in a simple manner. It is then ensured that the clamping springs cannot slide back the parts which are displaceable against one another, that is to say loose body and loose pressure piece.
Mit dem Losekorper kann ein Abschottungstell für die An- schlußoffnung der zugeordneten Klemme derart m Verbindung stehen, daß ohne angeschlossenen Leiter die Anschlußoffnung weitgehend oder völlig geschlossen ist. Die Erfindung soll nun anhand von m der Zeichnung grob schematisch wiedergegebenen Ausfuhrungsbeispielen naher erläutert werden :With the loose body, a partitioning point for the connection opening of the assigned terminal can be connected in such a way that the connection opening is largely or completely closed without a connected conductor. The invention will now be explained in more detail with reference to exemplary embodiments shown roughly schematically in the drawing:
In FIG 1 ist eine Anreihung von drei schraubenlosen Klemmen veranschaulicht, die mit einem Losekorper und einem Losedruckstuck, in Gestalt zweier sagezahnformiger gegeneinander verschieblicher Keile, zusammenarbeiten.FIG. 1 shows a series of three screwless clamps which work together with a loose body and a loose pressure piece, in the form of two sawtooth-shaped wedges which can be moved relative to one another.
In FIG 2 ist die Klemme nach FIG 1 von der Seite her gesehen wiedergegeben, wobei der Kopf des Betatigungsstoßels entferntFIG. 2 shows the clamp according to FIG. 1 seen from the side, with the head of the actuating plunger removed
In FIG 3 ist die Klemme nach FIG 1 im geöffneten Zustand lh- rer Klemmfedern veranschaulicht.3 shows the clamp according to FIG. 1 in the open state of its clamping springs.
In FIG 4 ist m Seitenansicht in der Darstellungsweise nach FIG 2 die Klemme nach FIG 3 wiedergegeben.FIG. 4 shows the side view in the representation according to FIG. 2 the clamp according to FIG. 3.
In FIG 5 ist ein Losekorper und ein Losedruckstuck, gebildet aus zwei gegeneinander verschieblichen Keilen m Sagezahnformation, dargestellt, wobei am Ende der aufspreizenden Verschiebungsstrecke jeweils eine Abflachung vorgesehen ist. Hierdurch kann die Offenstellung zugeordneter Klemmfedern oh- ne weitere äußere Einwirkung aufrechterhalten werden.5 shows a loose body and a loose pressure piece, formed from two mutually displaceable wedges m saw tooth formation, with a flattening being provided at the end of the spreading displacement distance. As a result, the open position of the associated clamping springs can be maintained without any further external action.
In FIG 6 ist ein Losekorper aus zwei gegeneinander verschieb¬ lichen Keilen m Sagezahnformation nach FIG 5 für die Losestellung zugeordneter Klemmfedern dargestellt.In FIG 6 a Losekorper of two against each other is displaceable ¬ union wedges m sawtooth formation according to FIG 5 is shown for the lots position associated clamping springs.
In FIG 7 ist ein Losekorper und ein Losedruckstuck aus zwei gegeneinander verschieblichen Keilen m Sagezahnformation nach Art der Darstellung von FIG 3 wiedergegeben, wobei jeweils für die Anschlußoffnung ein Abschottungstell vorgesehen ist, wie es aus FIG 8 zu ersehen ist. In FIG 8 ist m der Darstellungsweise nach FIG 4 die Seitenansicht einer Klemme nach FIG 7, mit einem Abschottungstell für die Anschlußoffnungen wiedergegeben.FIG. 7 shows a loose body and a loose piece made of two wedges that can be displaced relative to one another in a sawtooth formation in the manner of the representation in FIG. FIG. 8 shows the side view of a terminal according to FIG. 7, with a partitioning point for the connection openings, as shown in FIG. 4.
Die schraubenlose Klemme nach FIG 1 weist drei angereihte Klemmfedern 1 auf, die jeweils einen anzuschließenden Leiter 2 unter Federkraft mit einer Stromschiene 3, senkrecht zur Zeichenebene, in Verbindung bringen. Man vergleiche auch FIG 2. Mit der Klemmfeder 1 oder mit einem Losedruckstuck 4 steht m Loserichtung ein aufgleitender keilförmiger Losekorper 5 m Wirkverbindung. Für drei angereihte Klemmfedern 1 weist der keilförmige Losekorper 5 und das zugeordnete Losedruckstuck 4 die Formation eines Sagezahns auf. Der aufglei¬ tende Losekorper 5 und ein zugeordnetes Losedruckstuck 4 sind als zwei gegeneinander verschiebliche Keile ausgeführt, die jeweils die Formation eines Sagezahns aufweisen. Für eine Anreihung von schraubenlosen Klemmen steht also mit einem sage- zahnformigen Losekorper 5 über ein sagezahnformiges Losedruckstuck 4 in aufspreizender Wirkverbindung. Der Losekor- per 5 kann von der Seite her durch einen Stößel 6 betätigt werden .The screwless clamp according to FIG. 1 has three clamp springs 1 in series, each of which connects a conductor 2 to be connected under spring force to a busbar 3, perpendicular to the plane of the drawing. Also compare FIG. 2. With the clamping spring 1 or with a loose pressure piece 4, a sliding wedge-shaped loose body 5 m is connected in the loose direction. For three adjacent clamping springs 1, the wedge-shaped loose body 5 and the associated loose pressure piece 4 have the formation of a sawtooth. The aufglei ¬ tend Losekorper 5 and an associated pressure lots stucco 4 are designed as two mutually displaceable wedges, each having the formation of a forecast tooth. For a series of screwless terminals, a sawtooth-shaped loose body 5 is in a spreading operative connection via a sawtooth-shaped loose piece 4. The loose body 5 can be actuated from the side by a plunger 6.
Aus FIG 2 ist anschaulich zu ersehen, wie beim Aufspreizen von Losekorper 5 und von Losedruckstuck 4 eine Klemmfeder 1 in die Position 15 niedergedruckt wird m die zart gezeichnete Position. Man vergleiche hierzu die den FIG 1 und 2 ent¬ sprechenden FIG 3 und 4 für die Klemmfedern 1 m ihrer niedergedruckten Position. In der schlaufenformigen Klemmfeder 1, bei der ein Schenkel 7 durch ein Fenster 9 des anderen Schenkels 8 gesteckt ist, wird dieses Fenster 9 unter Druck durch den Losekorper und des Losedruckstucks mit seiner unteren Kante im Schenkel 8 freigegeben. Man kann dann einen Leiter 2 abziehen oder leicht einfuhren. Die nach den FIG 2 und 4 untere Kante 10 kann allgemein als außenliegende Kante des Fensters 9 bezeichnet werden. In FIG 1 sind die Fenster 9 bei nicht eingeführtem Leiter wiedergegeben, wobei der Anschaulichkeit wegen die Öffnung des Fensters 9 n der Klemmfeder so dargestellt ist, wie ein eingeführter Leiter dieses aufhalten wurde.From FIG. 2 it can be clearly seen how a clamping spring 1 is pressed down into position 15 when the loose body 5 and loose pressure piece 4 are spread apart m the delicately drawn position. This, compare the figures 1 and 2 ent ¬ speaking Figures 3 and 4 for the clamping springs 1 m down its printed position. In the loop-shaped clamping spring 1, in which one leg 7 is inserted through a window 9 of the other leg 8, this window 9 is released under pressure by the loose body and the loose pressure piece with its lower edge in the leg 8. You can then pull off a conductor 2 or easily insert it. The lower edge 10 according to FIGS. 2 and 4 can generally be referred to as the outer edge of the window 9. In FIG 1, the windows 9 are shown when the conductor is not inserted, with the opening of the window 9 n of the clamping spring for clarity is shown how an introduced conductor would stop it.
Der Losekorper 5 und das Losedruckstuck 4 nach FIG 5 sind im Endbereich ihrer aufspreizenden Verschiebungsstrecke mit einer Abflachung 11 versehen, wodurch Klemmen m ihrer Offenstellung bei der Stellung nach FIG 6 gehalten werden können, ohne daß die keilförmigen Flachen unter der Kraft der Klemmfedern zuruckgleiten können. Andererseits können Losekorper 5 und Losedruckstuck 4 im Endbereich ihrer aufspreizenden Verschiebungsstrecke aus verrastend ausgebildet sein, um eine Offenstellung der Klemme zu erzielen, bis der Stößel 6 wieder betätigt wird.The loose body 5 and the loose pressure piece 4 according to FIG. 5 are provided with a flattening 11 in the end region of their spreading displacement distance, as a result of which clamps can be held in their open position in the position according to FIG. 6 without the wedge-shaped surfaces being able to slide back under the force of the clamping springs. On the other hand, loose body 5 and loose pressure piece 4 can be designed to be latching in the end region of their spreading displacement distance in order to achieve an open position of the clamp until the plunger 6 is actuated again.
Im Ausfuhrungsbeispiel nach den FIG 7 und m der Seitenansicht hierzu nach FIG 8 steht mit dem Losekorper 5 ein Ab- schottungsteil 12 für die Anschlußoffnung 13 der zugeordneten Klemme m Verbindung. Bei geeigneter Formgebung kann das Ab- schottungsteil 12 bei einer Bewegung senkrecht zur Zeichene- bene nach FIG 8 die Anschlußoffnung 13 bei eingeführtem Leiter 2 weitgehend verschließen und ohne eingeführten Leiter soweit verschoben werden, daß die Anschlußoffnung 13 verschlossen ist. Verstandlicherweise empfiehlt es sich, das Ab- schottungsteil aus Isolierstoff zu fertigen. Für mehrere Klemmen können vorteilhaft separate Abschottungstelle vorgesehen werden. Vorteilhafterweise können die Abschottungsteile für den Losekorper federnd verbunden sein.In the exemplary embodiment according to FIGS. 7 and m the side view of this according to FIG. 8, the bulkhead 5 is a bulkhead part 12 for the connection opening 13 of the associated terminal m connection. With a suitable shape, the partitioning part 12 can largely close the connection opening 13 when the conductor 2 is inserted during a movement perpendicular to the plane of the drawing according to FIG. 8, and can be shifted so far without an inserted conductor that the connection opening 13 is closed. Understandably, it is advisable to manufacture the bulkhead part from insulating material. Separate partitioning points can advantageously be provided for several terminals. The bulkhead parts for the loose body can advantageously be resiliently connected.
Eine schraubenlose Klemme der geschilderten Art weist u.a. folgende Vorteile auf:A screwless clamp of the type described has, inter alia, the following advantages:
Die Betätigung der Klemme kann bei angereihten Gehäusen mit mehrstockiger Klemmenanordnung, wie sie bei Reihenklemmen üblich ist, von der Frontseite bedient werden. Es ist kein erhöhter Platzbedarf für Hilfsmittel zur Betäti¬ gung der Klemmfeder erforderlich, es ist also für einen Lose- emgriff kein Zugang freizuhalten. Man erzielt geringe Montagezeiten bei angereihten Klemmen durch gleichzeitiges Betätigen mehrerer Klemmen. Die Klemmfedern können hinsichtlich der Betatigungsseite vollständig isoliert werden und es entfallt die Isolierung eines Hilfsmittels, da dieses ohnehin nicht erforderlich ist Die Klemme kann im Bedarfsfall einfach so ausgeführt werden, daß eine stabile Offenhaltung erzielt wird.The actuation of the terminal can be operated from the front in a row of housings with a multi-level terminal arrangement, as is common with terminal blocks. It is no more space is required for aids for Actuate the ¬ the clamping spring supply required, so it's a loose-emgriff no access kept clear. Short assembly times can be achieved with aligned terminals by simultaneously operating several terminals. The clamping springs can be completely insulated with regard to the actuation side and there is no need to isolate an aid since this is not required anyway. If necessary, the clamp can simply be designed in such a way that stable opening is achieved.
Der Klemmzustand kann einfach sichtbar gemacht werden durch die Stellung des Losekorpers oder durch die Stellung eines Stoßeis. The clamped state can easily be made visible by the position of the loose body or by the position of an ice cream.
