The coupling region of the clamp spring lies on the opposite side of the contact body to the spring arm, the insulating block enclosing the clamp provided with positioning elements for both the contact body and the clamp spring.

Description

Die Erfindung betrifft eine in einem Isolierkörper angeordnete schraubenlose Anschluss- oder Verbindungsklemme für elektrische Leiter, insbes. für Lampen- oder Starterfassungen, Schalter od. dgl., umfassend je wenigstens einen Kontaktkörper und eine Klemmfeder aus unterschiedlichen Werkstoffen, wobei die Klemmfeder einen Verbindungsbereich, mit dem sie am Kontaktkörper festgelegt ist, und einen in Leitereinsteckrichtung sowie schräg gegen einen Abschnitt des Kontaktkörpers gerichteten Federschenkel aufweist, der den Leiter zwischen sich und dem Kontaktkörper klemmt.The invention relates to an arranged in an insulating body screwless connection or connection terminal for electrical Conductor, especially for lamp or starter sockets, switches or the like, each comprising at least one contact body and a clamping spring made of different materials, the clamping spring providing a connection area, with which it is fixed to the contact body, and one in the direction of insertion and at an angle to a section of the contact body directed spring leg, the conductor stuck between itself and the contact body.

Klemmen dieser Art sind vornehmlich deshalb zweiteilig aufgebaut, weil von ihnen einerseits eine hohe Stabilität und gute elektrische Leitfähigkeit verlangt werden, was durch einen z.B. aus Kupfer bestehenden Kontaktkörper erfüllt wird, und andererseits zuverlässige Klemmkräfte, die eine Klemmfeder bereitstellt, die auch unter Temperatureinwirkung optimale Federkräfte ausübt. Deshalb besteht eine solche Klemmfeder aus entsprechend geeignetem Material, z.B. aus einer CrNi-Legierung.Clamps of this type are primarily constructed in two parts, because on the one hand they have high stability and good electrical properties Conductivity are required, which is e.g. made of copper Contact body is met, and on the other hand reliable Clamping forces provided by a clamping spring that also under the influence of temperature exerts optimal spring forces. Therefore there is one such a clamping spring made of a suitable material, e.g. out a CrNi alloy.

Im Stand der Technik sind bei derartigen zweiteiligen Klemmen Kontaktkörper und Klemmfeder miteinander vernietet, wie dies beispielsweise die DE 38 01 480 C1 zeigt, oder mittels Ausstanzungen und umgeformten Lappen fest miteinander verbunden, wie es in DE 23 49 614 C2 dargestellt und beschrieben ist.The prior art includes two-part clamps of this type Contact body and clamping spring riveted together, such as this DE 38 01 480 C1 shows, or by punching and reshaped flap firmly connected as in DE 23 49 614 C2 is shown and described.

Die feste Verbindung - gleich welcher Art - von Kontaktkörper und Klemmfeder ist relativ aufwendig und erfordert zusätzliche Arbeitsschritte bei der Herstellung. The fixed connection - of whatever kind - from Contact body and clamping spring is relatively complex and requires additional production steps.

Der Erfindung liegt die Aufgabe zugrunde, eine schraubenlose Anschluss- bzw. Verbindungsklemme der als bekannt vorausgesetzten Art verfügbar zu machen, die bei einfachem Aufbau die Herstellung vereinfacht und die Montage erleichtert.The invention has for its object a screwless Connection or connecting terminal of the presupposed as known Art to make available, the manufacture with a simple structure simplified and assembly easier.

Die Erfindung löst diese Aufgabe mit den Merkmalen des Anspruchs 1 und ist dem entsprechend dadurch gekennzeichnet, dass der Verbindungsbereich von einem Klemmfederabschnitt ausgebildet ist, der sich auf der dem Federschenkel gegenüberliegenden Seite des Kontaktkörpers an diesem im wesentlichen druckschlüssig abstützt und dass der Isolierkörper Positionierelemente zur lagegerechten Zuordnung von Klemmfeder und Kontaktkörper ausbildet.The invention solves this problem with the features of Claim 1 and is accordingly characterized in that the connection area is formed by a clamping spring section is on the opposite side of the spring leg of the Contact body is supported on this essentially pressure-locking and that the insulating body positioning elements for correct position Assignment of clamping spring and contact body forms.

Entsprechend der Erfindung sind der Kontaktkörper und der Klemmfederabschnitt nicht mehr fest miteinander verbunden. Deshalb können diese beiden Bauelemente der Klemme auch unabhängig voneinander bzw. nacheinander in den Isolierkörper eingeführt werden, wozu dieser zweckmäßig Einschub-Aufnahmen für den Kontaktkörper und für die Klemmfeder ausbildet.According to the invention, the contact body and the Clamping spring section no longer firmly connected. Therefore these two components of the terminal can also be used independently are introduced into the insulating body from one another or one after the other, why this expedient insertion receptacles for the contact body and trains for the clamping spring.

Entsprechend der Erfindung liegt der Verbindungsabschnitt der Klemmfeder im wesentlichen unverspannt am Kontaktkörper an, wenn kein Leiter in der Klemme befindlich ist. Durch den zwischen Federschenkel und Kontaktkörper eingeführten Leiter bilden Federschenkel und Kontaktkörper in Folge der dadurch hervorgerufenen Verspannung eine selbsttragende Konstruktion aus. Die durch den eingeführten Leiter ausgeübten Spreizkräfte auf den Federschenkel und die von diesem ausgeübten Klemmkräfte werden von den zunächst nur lose in Relation zueinander positionierten Elementen aufgenommen und dadurch vom Isolierkörper ferngehalten. Dies hat den Vorteil, dass die in der Klemme herrschenden Kräfte keine den Isolierkörper in Mitleidenschaft ziehenden Auswirkungen haben. According to the invention, the connecting portion of the Clamping spring on the contact body essentially untensioned, if there is no conductor in the terminal. By between the spring legs and contact body inserted conductor form spring legs and contact body as a result of the resulting strain a self-supporting construction. The introduced by the Head exerted spreading forces on the spring leg and that of this exerted clamping forces are initially only loosely in Relative to each other positioned elements and thereby kept away from the insulating body. This has the advantage that the Forces in the clamp do not affect the insulating body pulling effects.

Die Aufnahmen des Isolierkörpers können den Kontaktkörper und die Klemmfeder bei deren Einsetzen im wesentlichen kraftlos führen. Kontaktkörper und Klemmfeder können auch in ihrer Endlage im Isolierkörper im wesentlichen kraftlos in diesen Aufnahmen liegen. Dies schließt nicht aus, dass, falls gewünscht, die Aufnahmen die Klemmenelemente - Kontaktkörper und Klemmfeder - auch zumindest leicht reib- bzw. klemmschlüssig fassen können, was insbesondere den Vorteil hat, dass die Elemente während der Konfektion des Geräts, in dem die Klemme untergebracht ist, nicht aus dem Isolierkörper herausfallen können. Am Prinzip der Erfindung ändert dies nichts.The recordings of the insulating body can the contact body and guide the clamping spring essentially without force when it is inserted. Contact body and clamping spring can also be in their end position Insulating bodies are essentially powerless in these recordings. This does not exclude that, if desired, the recordings Terminal elements - contact body and clamping spring - at least can easily grasp frictionally, what in particular has the advantage that the elements during the assembly of the Device in which the terminal is housed, not out of the insulating body can fall out. This changes in the principle of the invention Nothing.

Eine besonders einfache Ausgestaltung ergibt sich gemäß einer Weiterbildung dadurch, dass der Verbindungsbereich als abgebogene Zunge am freien Ende eines Kontaktfederabschnitts ausgebildet ist, und zwar bevorzugt an demjenigen Kontaktfederabschnitt, aus dem der Federschenkel ausgeklinkt ist.A particularly simple embodiment results according to one Training in that the connection area as a bent Tongue is formed at the free end of a contact spring section, and preferably at that contact spring section from which the spring leg is released.

Fig. 1 zeigt zwei schraubenlose Anschlussklemmen 10 und 11 sowie eine Schaltkontaktwippe 12.1 shows two screwless terminals 10 and 11 and a switch contact rocker 12.

Die Anschlussklemme 10 ist zweiteilig und besteht aus einem Kontaktkörper 13 sowie einer Klemmfeder 14. Ein bezüglich Fig. 1 oberer Schenkel 15 des Kontaktkörpers 13 trägt eine Kontaktwarze 16, der eine Kontaktwarze 17 an dem einen freien Ende der Schaltkontaktwippe 12 gegenübersteht. Der Kontaktkörper 18 der zweiten Anschlussklemme 11 weicht in der Formgestaltung vom Klemmkörper 13 insoweit ab, als hier ein nach oben ausgerichteter Schenkel 19 zur Lagerung der Schaltkontaktwippe 12 ausgebildet ist. Die Klemmfeder 14 der Anschlussklemme 11 ist mit der Klemmfeder 14 der Anschlussklemme 10 identisch.The terminal 10 is in two parts and consists of one Contact body 13 and a clamping spring 14. A with respect to FIG. 1 upper leg 15 of the contact body 13 carries a contact lug 16, one contact lug 17 on one free end of the switch contact rocker 12 faces. The contact body 18 of the second Terminal 11 differs in shape from the clamp body 13 to the extent that here an upward leg 19 for Storage of the switch contact rocker 12 is formed. The clamp spring 14 of the connection terminal 11 is with the clamping spring 14 of the connection terminal 10 identical.

Die Kontaktkörper 13 und 18 der Anschlussklemmen 10 und 11 sind die stromführenden Teile und bestehen aus einem elektrisch gut leitenden Material, insbes. aus Kupfer. Demgegenüber sind die Klemmfedern 14 aus einem optimale Federeigenschaften aufweisenden Material gefertigt, vorzugsweise aus einer CrNi-Legierung.The contact bodies 13 and 18 of the connection terminals 10 and 11 are the live parts and consist of an electrically good conductive material, especially made of copper. In contrast, they are Clamping springs 14 from an optimal spring properties Material made, preferably from a CrNi alloy.

Jede Klemmfeder 14 besteht aus einem im wesentlichen flachrechteckigen Blechstanzteil, aus dessen Ebene eine Federzunge 20 freigeschnitten und leicht ausgestellt ist, wie es Fig. 1 insbesondere in Verbindung mit Fig. 4 deutlich zeigt. Das freie Ende der Federzunge 20 bildet eine Klemmkante 21 zur Kontaktierung eines abisolierten Endes L eines elektrischen Leiters aus. In Einsteckrichtung x (Fig. 2) der Leiterenden L sind die Federzungen 20 geneigt angeordnet und weisen schräg in Richtung auf den jeweils unteren Schenkel 22 des Kontaktkörpers 13 bzw. 18.Each clamping spring 14 consists of an essentially flat rectangular Sheet metal stamped part, from the level of which a spring tongue 20 is cut free and easily issued, as shown in Fig. 1 in particular Connection with Fig. 4 clearly shows. The free end of the spring tongue 20 forms a clamping edge 21 for contacting a stripped End L of an electrical conductor. In the insertion direction x (Fig. 2) of the conductor ends L, the spring tongues 20 are arranged inclined and point obliquely in the direction of the respective lower leg 22 of the Contact body 13 or 18.

In der Klemmkante 21 etwa gegenüberliegender Anordnung weist das freie Ende jeder Klemmfeder 14 einen zum Schenkel 22 des Kontaktkörpers 13 bzw. 18 hin umgebogenes Ende 23 auf. Dieses umgebogene Ende 23 untergreift, wie die Figuren dies deutlich veranschaulichen, die Randkante des unteren Abschnittes 22 des Kontaktkörpers 23 bzw. des Kontaktkörpers 18 und liegt an der der Auflagefläche 24 für das abisolierte Leiterende 22 gegenüberliegenden Außenfläche 25 des Kontaktkörpers an.In the clamping edge 21 approximately opposite arrangement the free end of each clamp spring 14 has a leg 22 of the Contact body 13 or 18 bent end 23. This bent end 23 engages, as the figures clearly illustrate, the edge of the lower portion 22 of the contact body 23 or the contact body 18 and lies on that of the bearing surface 24 for the stripped conductor end 22 opposite Outer surface 25 of the contact body.

Da die Kontaktteile 13/14 bzw. 18/14 keine unmittelbare Verbindung miteinander eingehen, sorgen Positionierelemente im Isolierkörper 26 für eine lagegerechte Zuordnung der jeweiligen Klemmenelemente zueinander. Solche Positionierelemente bestehen z.B. aus nut- oder taschenförmigen Einschub-Aufnahmen, wie sie beispielhaft in Fig. 3 mit 27, 28 und 29 bezeichnet sind. In diese Aufnahmen 27 bis 29 werden die einzelnen Bauteile der Klemmen 10 und 11, also die beiden Kontaktkörper 13 und 18 sowie die beiden Klemmfedern 14 eingesetzt. Beim Ausführungsbeispiel geschieht dies von der Seite her in der Art und Weise, dass - bezogen auf die Zeichnungsebene der Fig. 3 - zunächst die Kontaktkörper 13 und 18 senkrecht in die zugehörigen Aufnahmen 28 bzw. 29 eingesetzt werden und danach die Klemmfedern 14 so, dass deren nach oben weisenden freien Enden in den Taschen 27 zu liegen kommen und die umgebogenen unteren Abschnitte 23 den jeweiligen Kontaktkörper 13 bzw. 18 untergreifen.Since the contact parts 13/14 and 18/14 are not a direct connection come together, ensure positioning elements in the insulating body 26 for a correct allocation of the respective terminal elements to each other. Such positioning elements are e.g. from nut- or pocket-shaped insert recordings, as exemplified in 3 are designated 27, 28 and 29. In these shots 27 to 29 are the individual components of terminals 10 and 11, that is two contact bodies 13 and 18 and the two clamping springs 14 used. In the exemplary embodiment, this is done from the side in the way that - based on the drawing level of the Fig. 3 - first the contact body 13 and 18 vertically into the associated Recordings 28 and 29 are used and then the Clamping springs 14 so that their free ends pointing upwards in the pockets 27 come to rest and the bent lower ones Sections 23 engage under the respective contact body 13 or 18.

Sofern noch keine Leiterenden L in die Klemmstellen eingeführt sind, entspricht die Konfiguration der Metallteile 13, 14 und 18 und ihre Zuordnung zueinander der Darstellung in Fig. 1. Das bedeutet, dass die Klemmfedern 14 mit ihren unteren abgewinkelten Abschnitten 23 den angrenzenden Klemmkörper 13 bzw. 18 nicht oder nur lose tangieren.If no conductor ends L have been inserted into the terminal points are the configuration of the metal parts 13, 14 and 18 and their Assignment to each other as shown in Fig. 1. This means that the clamping springs 14 with their lower angled sections 23 do not or only loosely touch the adjacent clamping body 13 or 18.

Wird nun ein Leiterende L von außen in eine Kontaktstelle eingeführt, zwingt es den Federschenkel 20 der Klemmfeder 14 entgegen der diesem immanenten Federkraft zum Aufspreizen, wie es die Fig. 2 und 3 deutlich machen. Hierdurch werden Federkräfte aufgebaut, die die abgewinkelten Enden 23 der Klemmfedern 14 fest gegen die Unterfläche 25 der Klemmkörper 13 und 18 verspannen. Nun bilden die jeweils beiden Teile 14 und 13 bzw. 14 und 18 jeder Anschlussklemme 10 und 11 eine selbsttragende Konstruktion, die die Klemmkräfte in sich selbst aufnimmt. Dies veranschaulicht Fig. 2, die erkennen läßt, dass die Klemmkante 21 des Federschenkels 20 der Klemmfeder 14 zusammen mit dem Federende 23 gewissermaßen eine Klemmzange ausbildet. In diesem Stadium ist die jeweilige Klemmfeder 14 mit dem zugeordneten Klemmkörper 13 bzw. 18 so fest und sicher verspannt, dass eine mechanische Fixierung ebenso gewährleistet ist wie eine sichere elektrische Kontaktierung. Die in den Anschlussklemmen 10 und 11 aufgebauten Kräfte werden praktisch nicht an den Isolierkörper 26 weitergegeben.Now becomes a conductor end L from the outside into a contact point introduced, it forces the spring leg 20 against the clamping spring 14 of this immanent spring force for spreading like the 2 and 3 clearly. This builds up spring forces the the angled ends 23 of the clamping springs 14 firmly against clamp the lower surface 25 of the clamping bodies 13 and 18. Now make up the two parts 14 and 13 or 14 and 18 each Terminal 10 and 11 is a self-supporting structure that the Absorbs clamping forces in itself. This illustrates Fig. 2, the reveals that the clamping edge 21 of the spring leg 20 of the Clamping spring 14 together with the spring end 23 to a certain extent forms a clamp. At this stage is the respective one Clamping spring 14 with the associated clamping body 13 or 18 so firmly and securely clamped that mechanical fixation as well What is guaranteed is safe electrical contacting. The in the Terminal 10 and 11 built-up forces become practical not passed on to the insulating body 26.

Fig. 4 veranschaulicht den Isolierkörper 26 mit allen wesentlichen Elementen noch einmal deutlich als perspektivische Darstellung. Mit dem Pfeil 30 ist die Einsteckrichtung der Kontaktkörper 13 und 18 wie auch der Klemmfedern 14 veranschaulicht.Fig. 4 illustrates the insulating body 26 with all essential Elements clearly again as a perspective representation. The arrow 30 indicates the direction of insertion of the contact bodies 13 and 18 as well as the clamping springs 14 illustrated.
