Definitions
- the invention relates to a screwless electrical connecting terminal with a receiving space in a housing for inserting an electrical conductor to be connected, an electrically conductive contact piece forming a fixed boundary of the receiving space, a leaf spring for pressing the electrical conductor against the contact piece within the receiving space and an actuating member for pushing back the Leaf spring from the pressing position, which actuating member can be moved manually transversely to the direction of insertion of the conductor and has two legs extending in its direction of movement, which are intended for cooperation with the leaf spring.
- GB-A-1 593 321 describes an electrical connecting terminal of this type, with a manually actuable lever which describes a pivoting movement, but in which a visual check of the correct clamping of the conductors is only possible by chance.
- the electrical connecting terminal according to the invention has the advantage that the electrical conductor is correctly connected from the position of the actuating member is recognizable.
- the electrical conductor is guided laterally securely through the legs which are moved along with the actuating member and which extend far beyond the electrical conductor.
- there is a lower loosening force to be exerted against the inclined leaf spring leg which, particularly when using the electrical clamp in an installation apparatus, must not be too great.
- an accommodation space 3 is formed for an electrical conductor 4 to be connected, which is only shown in FIG. 2 and which extends through a bore formed in the housing part 1 5 is inserted into the receiving space 3.
- This receiving space 3 is delimited on one side by an electrically conductive contact piece 6, which is fixedly arranged in the housing 1, 2.
- a leaf spring 7 extending into the receiving space 3 for the electrical conductor 4 is supported.
- This V-shaped, isosceles steel spring 7 is intended to press the clamping edge 8 on one leg of the electrical conductor 4 inserted into the receiving space 3 under the influence of the elasticity of the steel spring against the electrically conductive contact piece 6.
- the clamping edge 8 secures the electrical conductor 4 against being pulled out of the terminal. If the electrical conductor 4 is solid or stable enough, it only needs to be inserted against the action of the leaf spring 7. If the electrical conductor 4 is a strand of fine wire, the actuating member 10 arranged above the electrical contact piece 6 in a recess 9 in the housing 1, 2 must be pressed down.
- This actuator 10 shown in FIGS. 3 and 4 as a single part is solid in the upper part and then has two legs 11 and 12 which are parallel to one another and are of identical shape. The two legs 11 and 12 extend on both sides of the electrical contact piece 6 located between them into the receiving space 3 of the electrical conductor 4 to be inserted.
- the two legs 11 and 12 which are of identical design with respect to the outer shape, are stepped on one side so that an internal step shoulder 13 is present at this step, against which the leaf spring 7 with the clamping edge 8 abuts when no electrical conductor 4 is inserted.
- Each leg is at a short distance from this stepped shoulder 13 11, 12 at 16 somewhat protruding toward the leaf spring, as a result of which the actuating member 10 is in driving engagement with the leaf spring 7 via the two legs 11 and 12 when the leaf spring end having the clamping edge 8 has a pivoting movement when the electrical conductor 4 is inserted executes, wherein the two legs 11 and 12 carry out the same downward movement and at the same time in the direction of insertion of the electrical conductor, as a result of which the actuating element 10 assumes an inclined position at the end, as can be seen from FIG. 2.
- This position of the actuator 10 with respect to the housing 1, 2 visually recognizes the correct connection of the electrical conductor.
- this oblique position of the actuating member 10 which extends through the channel-shaped recess 9 in the housing 1, 2 into the receiving space 3 for the electrical conductor 4 to be inserted, it has one on the side opposite the stepping shoulder 13 with respect to the insertion direction of the electrical conductor Indentation 14, which extends over a large part of this side of the actuating member, which in other words is tapered in a wedge shape with a gradual reduction in cross-section to the narrowest point, while a widening is again present in the lowest leg section.
- the housing part 2 has at the end of the channel-shaped recess 9 a projection 15, via which the actuating member can be pushed over during assembly, but which then prevents the actuating member from falling out.
- the actuator 10 is depressed. In any case, the electrical conductor is laterally well guided through the legs 11 and 12 of the actuating member 10 which extend far into the receiving space 3 for the conductor. Due to the inclined position of the actuating member when the electrical conductor is inserted, the point of application for the release force to be taken out to remove the electrical conductor is also more favorable than is the case with known connecting terminals, which in turn has the consequence that, despite the higher clamping force achieved, as for the Contact parts used here without galvanic coating is required, the release force does not have to be increased in comparison with other known terminals of this type. This is an important point, especially when using the connection terminal for installation equipment, because the loosening force here must not be too high.
Abstract
Description
Die Erfindung betrifft eine schraubenlose elektrische Anschlussklemme mit einem Aufnahmeraum in einem Gehäuse zum Einführen eines anzuschliessenden elektrischen Leiters, einem eine feste Begrenzung des Aufnahmeraumes bildenden elektrisch leitenden Kontaktstück, einer Blattfeder zum Andrücken des elektrischen Leiters gegen das Kontaktstück innerhalb des Aufnahmeraumes und einem Betätigungsorgan zum Zurückdrängen der Blattfeder aus der Andrückstellung, welches Betätigungsorgan quer zur Einführrichtung des Leiters manuell bewegbar ist und zwei in seiner Bewegungsrichtung verlaufende Schenkel aufweist, die zum Zusammenarbeiten mit der Blattfeder bestimmt sind.The invention relates to a screwless electrical connecting terminal with a receiving space in a housing for inserting an electrical conductor to be connected, an electrically conductive contact piece forming a fixed boundary of the receiving space, a leaf spring for pressing the electrical conductor against the contact piece within the receiving space and an actuating member for pushing back the Leaf spring from the pressing position, which actuating member can be moved manually transversely to the direction of insertion of the conductor and has two legs extending in its direction of movement, which are intended for cooperation with the leaf spring.
Das Problem bei bekannten elektrischen Anschlussklemmen dieser Art besteht darin, dass beim Anschliessen eines flexiblen elektrischen Leiters, der als Litze aus verdrillten dünnen Einzeldrähten gebildet ist, dieser Leiter zwischen dem Kontaktstück und der Blattfeder flachgedrückt wird und darum eine seitliche Führung für die Litze vorhanden sein muss, wobei zusätzlich zu berücksichtigen ist, dass die Klemmstelle je nach dem vorhandenen Durchmesser des elektrischen Leiters an einer anderen Stelle liegt, eine Führung des Leiters aber in jedem dieser möglichen Fälle gewährleistet sein soll.The problem with known electrical connection terminals of this type is that when connecting a flexible electrical conductor, which is formed as a strand of twisted thin individual wires, this conductor is flattened between the contact piece and the leaf spring and therefore a lateral guide for the strand must be available , with additional consideration being given to the fact that the clamping point is at a different location depending on the diameter of the electrical conductor, but that the conductor should be guided in each of these possible cases.
Bei einer bekannten in der DE-PS 28 26 978 beschriebenen elektrischen Anschlussklemme dieser Art ist dies insbesondere bei einem elektrischen Leiter mit grossem Durchmesser nicht ausreichend der Fall. Wenn ein flexibler elektrischer Leiter seitlich ausweichen kann, führt dies zu einer unzulässig grossen Reduktion der Kontaktkraft und ausserdem wird auch die zum Herausziehen des Leiters aus der Klemme aufzuwende Auszugskraft unzulässig niedrig.In a known electrical connection terminal of this type described in DE-PS 28 26 978, this is particularly the case with an electrical conductor with a large diameter is not sufficient. If a flexible electrical conductor can move sideways, this leads to an impermissibly large reduction in the contact force and, moreover, the pull-out force to be pulled out of the terminal also becomes impermissibly low.
In der praktischen Anwendung solcher elektrischer Klemmen hat sich gezeigt, dass es von besonderem Vorteil ist, wenn sich bei einer Vielzahl von in einem Installationsapparat vorhandenen elektrischen Klemmen dieser Art das Festsitzen der Leiter leicht kontrollieren lässt, wobei eine visuelle Kontrolle am günstigsten ist, d.h. dass man an der Anschlussklemme selbst visuell erkennen kann, ob der elektrische Leiter richtig festgeklemmt ist.The practical application of such electrical terminals has shown that it is particularly advantageous if the tightness of the conductors can be easily checked in the case of a large number of electrical terminals of this type present in an installation apparatus, visual inspection being the most favorable, i.e. that you can visually see on the connection terminal itself whether the electrical conductor is properly clamped.
In GB-A-1 593 321 ist eine elektrische Anschlußklemme dieser Art beschrieben, mit einem manuell betätigbaren Hebel, der eine Schwenkbewegung beschreibt, aber bei dem eine visuelle Kontrolle der richtigen Festklemmung der Leiter nur zufällig möglich ist.GB-A-1 593 321 describes an electrical connecting terminal of this type, with a manually actuable lever which describes a pivoting movement, but in which a visual check of the correct clamping of the conductors is only possible by chance.
Es ist daher die Aufgabe der Erfindung, eine schraubenlose elektrische Anschlussklemme der eingangs genannten Art so auszubilden, dass für elektrische Leiter mit unterschiedlich grossem Durchmesser beim Einführen und Klemmen eine sichere Führung gewährleistet ist und dass man das Festsitzen des Leiters an der Stellung des Betätigungsorgans für die Blattfeder erkennen kann.It is therefore the object of the invention to design a screwless electrical connection terminal of the type mentioned in such a way that reliable guidance is ensured for electrical conductors with different diameters during insertion and clamping and that the conductor is stuck at the position of the actuating member for the Leaf spring can recognize.
Die Aufgabe wird bei der elektrischen Anschlussklemme der gattungsgemässen Art mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmalen gelöst. Eine zweckmässige Ausführungsform ergibt sich aus den abhängigen Ansprüchen.The object is achieved in the electrical connection terminal of the generic type with the features specified in the characterizing part of
Die erfindungsgemässe elektrische Anschlussklemme besitzt den Vorteil, dass der korrekt erfolgte Anschluss des elektrischen Leiters aus der Stellung des Betätigungsorgans erkennbar ist. Der elektrische Leiter wird seitlich sicher durch die mit dem Betätigungsorgan mitbewegten und den elektrischen Leiter weit übergreifende Schenkel geführt. Bei der nach dem Einführen des elektrischen Leiters von dem Betätigungsorgan eingenommenen Schräglage ergibt sich eine gegen den schräg stehenden Blattfederschenkel auszuübende geringere Lösekraft, die insbesondere bei Anwendung der elektrischen Klemme in einem Installationsapparat nicht zu gross sein darf.The electrical connecting terminal according to the invention has the advantage that the electrical conductor is correctly connected from the position of the actuating member is recognizable. The electrical conductor is guided laterally securely through the legs which are moved along with the actuating member and which extend far beyond the electrical conductor. In the case of the inclined position taken up by the actuating member after the electrical conductor has been inserted, there is a lower loosening force to be exerted against the inclined leaf spring leg, which, particularly when using the electrical clamp in an installation apparatus, must not be too great.
Ein Ausführungsbeispiel des Erfindungsgegenstandes wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:
- Fig. 1 die elektrische Anschlussklemme in einem abgebrochen und im Schnitt dargestellten Gehäuse, ohne elektrischen Leiter;
- Fig. 2 eine zu Fig. 1 analoge Darstellung mit durch die Anschlussklemme festgehaltenem elektrischen Leiter;
- Fig. 3 und 4 das Betätigungsorgan im Schnitt und in Seitenansicht.
- Figure 1 shows the electrical terminal in a broken and sectioned housing, without an electrical conductor.
- FIG. 2 shows an illustration analogous to FIG. 1 with the electrical conductor held by the connecting terminal;
- 3 and 4, the actuator in section and in side view.
In einem aus Isoliermaterial bestehenden, abgebrochen dargestellten Gehäuse 1,2, das beispielsweise einen Schalter oder eine Steckdose bilden kann, ist ein Aufnahmeraum 3 für einen nur in Fig. 2 dargestellten anzuschliessenden elektrischen Leiter 4 ausgebildet, der durch eine in dem Gehäuseteil 1 ausgebildete Bohrung 5 in den Aufnahmeraum 3 eingeführt wird. Dieser Aufnahmeraum 3 ist an einer Seite durch ein elektrisch leitendes Kontaktstück 6 begrenzt, das im Gehäuse 1,2 fest angeordnet ist. Auf der dem Kontaktstück gegenüberliegenden Seite ist eine in den Aufnahmeraum 3 für den elektrischen Leiter 4 sich hinein erstreckende Blattfeder 7 abgestützt gehalten. Diese V-förmige, gleichschenklige Stahlfeder 7 ist dazu bestimmt, mit der Klemmkante 8 an ihrem einen Schenkel den in den Aufnahmeraum 3 eingeführten elektrischen Leiter 4 unter dem Einfluss der Elastizität der Stahlfeder gegen das elektrisch leitende Kontaktstück 6 anzudrücken. Die Klemmkante 8 bewirkt eine Sicherung des elektrischen Leiters 4 gegen eine Herausziehen aus der Klemme. Wenn der elektrische Leiter 4 massiv oder stabil genug ist, braucht er nur gegen die Wirkung der Blattfeder 7 eingeführt zu werden. Handelt es sich bei dem elektrischen Leiter 4 um eine Litze aus feinem Drähten, ist das oberhalb des elektrischen Kontaktstückes 6 in einer Ausnehmung 9 im Gehäuse 1,2 angeordnete Betätigungsorgan 10 nieder zu drücken. Dieses in Fig. 3 und 4 als Einzelteil dargestellte Betätigungsorgan 10 ist im oberen Teil massiv und besitzt daran anschliessend zwei zueiander parallele Schenkel 11 und 12, die formidentisch ausgebildet sind. Die beiden Schenkel 11 und 12 erstrecken sich zu beiden Seiten des zwischen ihnen befindlichen elektrischen Kontaktstücks 6 in den Aufnahmeraum 3 des einzuführenden elektrischen Leiter 4 hinein. Die beiden bezüglich der Aussenform identisch ausgebildeten Schenkel 11 und 12 sind an einer Seite stufenförmig abgesetzt ausgebildet, so dass bei dieser Stufe eine inwendige Stufenschulter 13 vorhanden ist, gegen welche die Blattfeder 7 mit der Klemmkante 8 ansteht, wenn kein elektrischer Leiter 4 eingeführt ist. Im geringen Abstand von dieser Stufenschulter 13 ist jeder Schenkel 11,12 bei 16 zur Blattfeder hin etwas vorspringend ausgebildet, wodurch bewirkt wird, dass das Betätigungsorgan 10 über die beiden Schenkel 11 und 12 mit der Blattfeder 7 in Mitnahmeeingriff steht, wenn das die Klemmkante 8 aufweisende Blattfederende beim Einführen des elektrischen Leiters 4 eine Schwenkbewegung ausführt, wobei die beiden Schenkel 11 und 12 die gleiche Bewegung nach unten und gleichzeitig in der Einführrichtung des elektrischen Leiters mitausführen, wodurch das Betätigungsorgan 10 am Ende eine Schräglage einnimmt, wie aus Fig. 2 hervorgeht. Diese Stellung des Betätigungsorgans 10 bezüglich des Gehäuses 1,2 zeigt den korrekt erfolgten Anschluss des elektrischen Leiters visuell erkennbar an.In a
Damit diese Schrägstellung des durch die kanalförmige Ausnehmung 9 im Gehäuse 1,2 sich bis in den Aufnahmeraum 3 für den einzuführenden elektrischen Leiter 4 hineinerstreckenden Betätigungsorgans 10 möglich ist, weist dieses auf der bezüglich der Einführrichtung des elektrischen Leiters rückwärtigen und der Stufenschulter 13 gegenüberliegenden Seite eine Einbuchtung 14 auf, die sich über einen grossen Teil dieser Seite des Betätigungsorgans erstreckt, welches mit anderen Worten mit einer allmählichen Querschnittsreduktion bis zur engsten Stelle keilförmig verjüngt ausgebildet ist, während im untersten Schenkelabschnitt wieder eine Verbreiterung vorhanden ist. Ferner besitzt der Gehäuseteil 2 am Ende der kanalförmigen Ausnehmung 9 einen Vorsprung 15, über den sich das Betätigungsorgan bei der Montage mit Druck herüberschieben lässt, der aber dann verhindert, dass das Betätigungsorgan herausfallen kann.So that this oblique position of the actuating
Wenn der elektrische Leiter aus einer feinadrigen Litze besteht, wird das Betätigungsorgan 10 niedergedrückt. Auf jeden Fall ist der elektrische Leiter durch die weit in den Aufnahmeraum 3 für den Leiter hineinreichenden Schenkel 11 und 12 des Betätigungsorgans 10 seitlich gut geführt. Durch die Schräglage des Betätigungsorgans bei eingeführtem elektrischen Leiter wird auch der Angriffspunkt für die zum Herausnehmen des elektrischen Leiters aufzuwendende Lösekraft günstiger, als dies bei bekannten Anschlussklemmen der Fall ist, was wiederum zur Folge hat, dass trotz der erreichten höheren Klemmkraft, wie sie für die hier verwendeten Kontaktteile ohne galvanischen Ueberzug benötigt wird, die Lösekraft im Vergleich mit anderen bekannten Klemmen dieser Art nicht erhöht werden muss. Dies ist besonders bei Verwendung der Anschlussklemme für Installationsapparate ein wichtiger Punkt, weil die Lösekraft hier nicht zu hoch sein darf.If the electrical conductor consists of a fine-stranded strand, the
