Abstract

Hauptbestandteil dieser konstruktiv einfachen elektrischen Klemme (10) ist ein etwa V-förmig gebogenes Blattfederstück (11), dessen V-Schenkel (11a, 11b) gegeneinander abgewinkelte, einander überlappende Endpartien (11d, 11e) aufweisen. Jede dieser Endpartien ist mit einer Durchbrechung (12, 13) zum Hindurchstecken mindestens eines anzuschliessenden elektri­schen Leiters (20) versehen. Die beiden Durchbrechungen (12, 13) haben in entspanntem Zustand des Blattfederstückes (11) in bezug aufeinander versetzte Lagen, sind jedoch miteinander zur Deckung bringbar durch Gegeneinanderdrängen der V-Schenkel (11a, 11b) entgegen dem Einfluss der Biegeelastizität des Blattfederstückes (11). Einer der V-Schenkel (11a) ist an einem Trag- und Kontaktstück (16) befestigt, das einen zur abgewinkelten Endpartie (11d) dieses V-Schenkels parallel verlaufenden Lappen (16a) aufweist. Im letzteren befindet sich ebenfalls eine Durchbrechung (18), die mit der Durchbre­chung (12) der letztgenannten abgewinkelten Endpartie (11d) deckungsgleich ist. Zum Anschliessen oder Lösen eines oder mehrerer elektrischer Leiter werden alle drei Durchbrechun­gen in übereinstimmende Lagen gebracht. Durch die Biege­elastizität des Blattfederstückes (11) lassen sich die ein­geführten Leiter festklemmen.

The main component of this simple electrical clamp (10) is an approximately V-shaped leaf spring piece (11), the V-legs (11a, 11b) of which have angled, overlapping end portions (11d, 11e). Each of these end parts is provided with an opening (12, 13) for inserting at least one electrical conductor (20) to be connected. In the relaxed state of the leaf spring piece (11), the two openings (12, 13) have positions which are offset with respect to one another, but can be made to coincide with one another by pushing the V-legs (11a, 11b) against each other against the influence of the bending elasticity of the leaf spring piece (11). . One of the V-legs (11a) is fastened to a support and contact piece (16) which has a tab (16a) which runs parallel to the angled end part (11d) of this V-leg. In the latter there is also an opening (18) which is congruent with the opening (12) in the latter angled end section (11d). To connect or disconnect one or more electrical conductors, all three openings are brought into matching positions. Due to the bending elasticity of the leaf spring piece (11), the inserted conductor can be clamped.

Die in den Fig. 1 bis 4 dargestellte schraubenlose elektri­sche Klemme 10 weist ein im wesentlichen etwa V-förmig ge­bogenes Blattfederstück 11 mit einem ersten und einem zweiten V-Schenkel 11a bzw. 11b auf, die je geradlinig verlaufen und im V-Scheitel durch eine kreisbogenförmig verlaufende Schei­telpartie 11c miteinander verbunden sind. Von der Scheitel­partie 11c abgewandte Endpartien 11d und 11e der beiden V-­Schenkel sind gegeneinander abgewinkelt und derart angeord­net und ausgebildet, dass sie sich überlappen. Die abgewinkel­ten Endpartien 11d und 11e sind je mit einer ersten bzw. zwei­ten kreisförmigen Durchbrechung 12 bzw. 13 versehen. In ent­spanntem Zustand des Blattfederstückes 11 schliessen die V-­Schenkel 11a und 11b zwischen sich einen Winkel im Bereich von 110° bis 140° ein, vorzugsweise von 130°, und die beiden Durchbrechungen 12 und 13 haben in bezug aufeinander ver­setzte Lagen, wie deutlich in Fig. 1 zu sehen ist. Durch Gegeneinanderdrängen der V-Schenkel 11a und 11b entgegen dem Einfluss der Biegeelastizität des Blattfederstückes 11 sind die Durchbrechungen 12 und 13 miteinander zur Deckung bring­bar. Zweckmässig haben die abgewinkelten Endpartien 11d und 11e je mindestens zum Teil einen annähernd kreisbogenförmi­ gen Verlauf um die Krümmungsachse 14 der Scheitelpartie 11c. Das Blattfederstück 11 besteht aus elektrisch leitendem Ma­terial, z.B. nichtrostendem Stahl oder Federbronze.The screwless electrical terminal 10 shown in FIGS. 1 to 4 has an essentially approximately V-shaped leaf spring piece 11 with a first and a second V-leg 11a or 11b, each of which extends in a straight line and in the V-apex through a apex portion 11c running in a circular arc are connected to one another. End parts 11d and 11e of the two V-legs facing away from the apex part 11c are angled towards one another and arranged and designed such that they overlap. The angled end portions 11d and 11e are each provided with a first and a second circular opening 12 and 13, respectively. In the relaxed state of the leaf spring piece 11, the V-legs 11a and 11b enclose an angle between them in the range from 110 ° to 140 °, preferably from 130 °, and the two openings 12 and 13 have positions offset with respect to one another, as clearly shown in FIG Fig. 1 can be seen. By pushing the V-legs 11a and 11b against each other against the influence of the bending elasticity of the leaf spring piece 11, the openings 12 and 13 can be brought into register with one another. Appropriately, the angled end portions 11d and 11e each have an approximately circular arc shape, at least in part gene course around the axis of curvature 14 of the apex 11c. The leaf spring piece 11 is made of electrically conductive material, for example stainless steel or spring bronze.

Einer (11a) der V-Schenkel 11a und 11b ist z.B. mittels Schweisspunkten 15 oder durch (nicht dargestellte) Nieten an einem elektrisch leitenden Trag- und Kontaktstück 16 be­festigt. Letzteres weist einen abgewinkelten Lappen 16a auf, der etwa parallel zur abgewinkelten Endpartie 11d am Trag- und Kontaktstück 16 befestigten V-Schenkels 11a verläuft. Zwischen der genannten Endpartie 11d und dem Lappen 16a ist ein freier Zwischenraum 17 vorhanden, in welchen die abge­winkelte Endpartie 11e des andern V-Schenkels 11b eingreift. Der Lappen 16a des Trag- und Kontaktstückes 16 weist eine dritte Durchbrechung 18 auf, die mit der Durchbrechung 12 der Endpartie 11d des am Trag- und Kontaktstück 16 befestigten V-Schenkels 11a deckungsgleich ist.One (11a) of the V-legs 11a and 11b is e.g. attached to an electrically conductive support and contact piece 16 by means of welding points 15 or by rivets (not shown). The latter has an angled tab 16a, which runs approximately parallel to the angled end portion 11d on the support and contact piece 16 V-leg 11a. There is a free space 17 between the end portion 11d and the tab 16a, in which the angled end portion 11e of the other V-leg 11b engages. The tab 16a of the support and contact piece 16 has a third opening 18, which is congruent with the opening 12 of the end part 11d of the V-leg 11a attached to the support and contact piece 16.

Die Gebrauchs- und Wirkungsweise der beschriebenen Klemme ist wie folgt:The use and mode of operation of the clamp described is as follows:

Um einen oder mehrere elektrische Leiter mit dem Trag- und Kontaktstück 16 zu verbinden, wird zuerst auf das Blattfeder­stück 11 eine Kraft in Richtung des Pfeiles P in Fig. 1 aus­geübt, wodurch der V-Schenkel 11b gegen den am Trag- und Kontaktstück 16 befestigten und damit stationären V-Schenkel 11a gedrängt wird, bis die Durchbrechung 13 der abgewinkel­ten Endpartie 11e des beweglichen anderen V-Schenkels 11b eine mit den Durchbrechungen 12 und 18 der anderen abgewinkel­ten Endpartie 11d bzw. des Lappens 16a übereinstimmend Lage erreicht. Dann wird der anzuschliessende Leiter 20 (Fig. 4) in alle drei Durchbrechungen 18, 13 und 12 eingeführt, wonach man die gemäss dem Pfeil P (Fig. 1) ausgeübte Kraft wegnimmt. Unter dem Einfluss seiner eigenen Biegeelastizität versucht dann das Blattfederstück 11 in seinen entspannten Zustand zu­ rückzukehren, wobei der Leiter 20 mittels der in Fig. 4 un­teren Umfangspartie der Durchbrechung 13 gegen die oberen um­fangspartien der stationären Durchbrechungen 12 und 18 ge­drückt und damit festgeklemmt wird. Man erkennt, dass nun der Leiter 20 durch drei Kanten festgehalten wird und gegen Her­ausziehen aus der Klemme gesichert ist. Der im Vergleich zu den abgewinkelten Endpartien 11d und 11e des Blattfeder­stückes 11 mehrfach stärkere Lappen 16a des Trag- und Kon­taktstückes 16 verhindert wirksam eine allfällige Deforma­tion der Endpartien 11d und 11e, wenn auf den Leiter 20 Kräfte im Sinne des Herausziehens aus der Klemme ausgeübt werden sollten.In order to connect one or more electrical conductors to the support and contact piece 16, a force is first exerted on the leaf spring piece 11 in the direction of the arrow P in FIG. 1, as a result of which the V-leg 11b is fixed against the one on the support and contact piece 16 and thus stationary V-leg 11a is pushed until the opening 13 of the angled end portion 11e of the movable other V-leg 11b reaches a position corresponding to the openings 12 and 18 of the other angled end portion 11d or of the flap 16a. Then the conductor 20 to be connected (FIG. 4) is inserted into all three openings 18, 13 and 12, after which the force exerted according to the arrow P (FIG. 1) is removed. Under the influence of its own bending elasticity, the leaf spring piece 11 then tries to relax to return, wherein the conductor 20 is pressed by means of the lower peripheral part of the opening 13 in FIG. 4 against the upper peripheral parts of the stationary openings 12 and 18 and thus clamped. It can be seen that the conductor 20 is now held by three edges and is secured against being pulled out of the terminal. The flap 16a of the support and contact piece 16, which is several times stronger than the angled end parts 11d and 11e of the leaf spring piece 11, effectively prevents any deformation of the end parts 11d and 11e if forces should be exerted on the conductor 20 in the sense of being pulled out of the clamp .

Auf die beschriebene Weise lassen sich auch mehrere elektri­sche Leiter kleineren Durchmessers mit der Klemme verbinden und mit dem Trag- und Kontaktstück 16 elektrisch kontaktieren.In the manner described, several electrical conductors of smaller diameter can also be connected to the terminal and electrically contacted with the support and contact piece 16.

Zum Lösen des Leiters 20 (oder mehrerer angeschlossener Lei­ter) braucht man lediglich wieder eine Kraft gemäss dem Pfeil P in Fig. 1 auf das Blattfederstück 11 auszuüben, wobei der Klemmdruck auf den oder die Leiter nachlässt und dann dem Herausziehen des Leiters 20 oder der Leiter nichts mehr im Wege steht.To release the conductor 20 (or several connected conductors), one only needs to exert a force again on the leaf spring piece 11 according to the arrow P in FIG. 1, the clamping pressure on the conductor or conductors releasing and then pulling out the conductor 20 or the conductor nothing stands in the way.

Die beschriebene Klemme 10 eignet sich z.B. als Anschluss­klemme an einem elektrischen Gerät.The clamp 10 described is suitable e.g. as a connection terminal on an electrical device.

In Fig. 5 ist gezeigt, wie ein Paar Klemmen 10 und 10' der beschriebenen Ausbildung mit einem gemeinsamen Trag- und Kon­taktstück 16 angeordnet sein können, das ausser dem bereits erwähnten abgewinkelten Lappen 16a noch einen zweiten abge­winkelten Lappen 16b aufweist, der ein Bestandteil der zwei­ten Klemme 10' mit einem Blattfederstück 11' ist. Während die eine Klemme 10 (rechts in Fig. 5) zum Einführen der anzu­schliessenden Leiter in waagrechter Richtung ausgebildet ist, wie beim Beispiel gemäss den Fig. 1 bis 4, hat die zweite Klemme 10' in Fig. 5 eine um 90° gedrehte Lage, so dass die an ihr anzuschliessenden Leiter in vertikaler Richtung von oben her einzuführen sind. Abgesehen von diesem Unterschied in der räumlichen Anordnung haben die beiden Klemmen 10 und 10' jedoch völlig übereinstimmende konstruktive Ausbildungen und sinngemäss gleiche Wirkungsweisen.In Fig. 5 it is shown how a pair of clamps 10 and 10 'of the embodiment described can be arranged with a common support and contact piece 16 which, in addition to the angled tab 16a already mentioned, has a second angled tab 16b which is part of the second clamp 10 'with a leaf spring piece 11'. While one terminal 10 (on the right in FIG. 5) is designed to insert the conductors to be connected in a horizontal direction, As in the example according to FIGS. 1 to 4, the second terminal 10 'in FIG. 5 has a position rotated by 90 °, so that the conductors to be connected to it are to be inserted in the vertical direction from above. Apart from this difference in the spatial arrangement, the two terminals 10 and 10 ', however, have completely identical structural designs and correspondingly the same modes of operation.

Das Klemmenpaar 10, 10' gamäss Fig. 5 ist in ein aus Isolier­material bestehendes Gehäuse 21 eingesetzt, und zwar durch eine Oeffnung 22 hindurch, die nachher durch einen einge­pressten Deckel 23 verschlossen wurde. Das Gehäuse 21 weist eine erste trichterartig geformte Oeffnung 24 zum waagrech­ten Einführen von Leitern in die Klemme 10 sowie eine zweite ebenfalls trichterartig geformte Oeffnung 25 zum vertikalen Einführen von Leitern in die Klemme 10' auf. Weiter ist das Gehäuse 21 mit einer Oeffnung 26 versehen, die erlaubt, mit­tels eines (nicht gezeichneten) Stosswerkzeuges, z.B. eines Schraubenziehers, die V-Schenkel des Blattfederstückes der ersten Klemme 10 von oben her gegeneinander zu drängen. Schliesslich ist am Gehäuse 21 noch eine weitere Oeffnung 27 vorhanden, die gestattet, mittels eines stabförmigen Werk­zeuges, z.B. eines Schraubenziehers, die V-Schenkel des Blatt­federstückes der zweiten Klemme 10' in etwa horizontaler Richtung gegeneinander zu drängen. Das Ganze dient als Lei­terverbinder, der ermöglicht, zwei oder mehr elektrische Lei­ter miteinander zu verbinden.5 is inserted into a housing 21 made of insulating material, specifically through an opening 22, which was subsequently closed by a pressed-in cover 23. The housing 21 has a first funnel-shaped opening 24 for the horizontal insertion of conductors into the clamp 10 and a second likewise funnel-shaped opening 25 for the vertical insertion of conductors into the clamp 10 '. Furthermore, the housing 21 is provided with an opening 26, which allows an impact tool (not shown), e.g. a screwdriver to urge the V-legs of the leaf spring piece of the first clamp 10 against each other from above. Finally, there is a further opening 27 on the housing 21, which allows a rod-shaped tool, e.g. a screwdriver to urge the V-legs of the leaf spring piece of the second clamp 10 'against each other in an approximately horizontal direction. The whole serves as a conductor connector, which enables two or more electrical conductors to be connected to one another.

Die Fig. 6 und 7 zeigen, dass parallel neben dem beschriebe­nen Gehäuse 21 ein gleich ausgebildetes zweites Gehäuse 21' angeordnet und durch einen Steg 28 mit dem ersten Gehäuse 21 verbunden sein kann. Im zweiten Gehäuse 21' befindet sich ein gleiches Klemmenpaar wie im Gehäuse 21. Der Steg 28 weist eine durchgehende Bohrung 29 auf, die zum Hindurchführen einer (nicht dargestellten) Befestigungsschraube dient, mit deren Hilfe die beiden Gehäuse 21 und 21' auf einer geeigneten Un­terlage festgemacht werden können.6 and 7 show that, in addition to the housing 21 described, a second housing 21 ′ of the same design can be arranged in parallel and connected to the first housing 21 by a web 28. In the second housing 21 'there is the same pair of clamps as in the housing 21. The web 28 has a through bore 29 which serves for the passage of a fastening screw (not shown) by means of which the two housings 21 and 21' are placed on a suitable base can be moored.

Die beschriebenen Klemmen 10 und 10' haben den Vorteil, kon­struktiv einfach und wenig störungsanfällig zu sein, verhält­nismässig wenig Raum zu beanspruchen und preisgünstig herge­stellt werden zu können. Sie eignen sich besonders zum An­schliessen oder Verbinden von elektrischen Signal- und Steuer­leitungen.The clamps 10 and 10 'described have the advantage of being structurally simple and less prone to malfunction, taking up relatively little space and being able to be produced inexpensively. They are particularly suitable for connecting or connecting electrical signal and control lines.

Das in den Fig. 8 bis 11 dargestellte zweite Ausführungs­beispiel der schraubenlosen elektrischen Klemme 10" unter­scheidet sich vom Beispiel nach den Fig. 1 bis 4 wie folgt:The second exemplary embodiment of the screwless electrical terminal 10 ″ shown in FIGS. 8 to 11 differs from the example according to FIGS. 1 to 4 as follows:

Die erste und die zweite Durchbrechung 12' bzw. 13' der bei­den gegeneinander abgewinkelten Endpartien 11d und 11e des Blattfederstückes 11 sind je rechteckförmig. Ebenso hat die dritte Durchbrechung 18' des abgewinkelten Schenkels 16a des Trag- und Kontaktstückes 16 eine rechteckige Form die sich mit der Durchbrechung 12' des am Trag- und Kontakstück 16 befestigten V-Schenkels 11a Blattfederstückes 11 weit­gehend deckt. Die dritte Durchbrechung 18' ist durch Aus­stanzen und abwinkeln einer Zunge 16b gebildet, welche durch die beiden Durchbrechungen 12' und 13' des Blattfederstückes 11 hindurch ragt, wie am deutlichsten in Fig. 8 zu sehen ist. Diese Zunge 16b befindet sich bei der vom befestigten V-­Schenkel 11a entfernteren Randkante der Durchbrechung 12' und bildet eine Anlagefläche für den anzuschliessenden elektrischen Leiter 20, wie Fig. 11 zeigt.The first and the second opening 12 'and 13' of the two end parts 11d and 11e of the leaf spring piece 11 which are angled relative to one another are each rectangular. Likewise, the third opening 18 'of the angled leg 16a of the support and contact piece 16 has a rectangular shape which largely coincides with the opening 12' of the V-leg 11a leaf spring piece 11 fastened to the support and contact piece 16. The third opening 18 'is formed by punching out and angling a tongue 16b which protrudes through the two openings 12' and 13 'of the leaf spring piece 11, as can be seen most clearly in FIG. 8. This tongue 16b is located at the edge of the opening 12 'which is more distant from the fixed V-leg 11a and forms a contact surface for the electrical conductor 20 to be connected, as shown in FIG. 11.

Die Gebrauchsweise der Klemme 10" gemäss den Fig. 8 bis 11 ist gleich wie jene des ersten Ausführungsbeispiels. Aus Fig. 11 ist aber ersichtlich, dass der angeschlossene elektri­sche Leiter 20 unter dem Einfluss der Elastizität des unbela­steten Blattfederstückes 11 mittels der unteren Kante der Durchbrechung 13' des beweglichen V-Schenkels 11b an die Zun­ge 16b des Trag- und Kontaktstückes 16 angedrückt wird. Hier­bei resultiert eine grössere Kontaktfläche zwischen dem Lei­ ter 20 und dem Trag- und Kontaktstück 16 als beim ersten Ausführungsbeispiel, was die Verwendung dieser Klemme 10" für höhere Stromstärken erlaubt.The use of the clamp 10 "according to FIGS. 8 to 11 is the same as that of the first exemplary embodiment. However, from FIG. 11 it can be seen that the connected electrical conductor 20 under the influence of the elasticity of the unloaded leaf spring piece 11 by means of the lower edge of the opening 13 'of the movable V-leg 11b is pressed against the tongue 16b of the support and contact piece 16. This results in a larger contact area between the lead ter 20 and the support and contact piece 16 than in the first embodiment, which allows the use of this terminal 10 "for higher currents.

Zweckmässig ist das Blattfederstück 11 beim zweiten Ausfüh­rungsbeispiel der Klemme derart vorgespannt, dass im Ruhezu­stand gemäss Fig. 8, d.h. wenn noch kein elektrischer Leiter angeschlossen ist, die untere Randkante der Durchbrechung 13' des beweglichen V-Schenkels 11b mit einer Vorspannkraft an die Zunge 16b angedrückt wird. Durch diese Massnahme er­gibt sich ein ausreichend hoher Kontaktdruck beim Anschlies­sen dünner Leiter und von Litzen, deren Querschnitt beim Ein­klemmen flach geformt wird. Durch die Vorspannung des Blatt­federstückes 11 wird auch erreicht, dass der angeschlossene Leiter 20 allein mittels der in Fig. 11 unteren Randkante der Durchbrechung 13' des beweglichen V-Schenkels 11b gegen Herausziehen aus der Klemme 10" genügend gesichert ist.In the second exemplary embodiment of the clamp, the leaf spring piece 11 is expediently pretensioned in such a way that in the idle state according to FIG. if no electrical conductor is connected yet, the lower edge of the opening 13 'of the movable V-leg 11b is pressed against the tongue 16b with a prestressing force. This measure results in a sufficiently high contact pressure when connecting thin conductors and strands, the cross section of which is formed flat when pinched. The pretensioning of the leaf spring piece 11 also ensures that the connected conductor 20 is sufficiently secured against being pulled out of the clamp 10 "solely by means of the lower edge of the opening 13 'of the movable V-leg 11b in FIG. 11.

Selbstverständlich kann ein Paar Klemmen 10" der mit Bezug auf die Fig. 8 bis 11 beschriebenen zweiten Ausführungsform ein gemeinsames Kontaktstück 16 aufweisen, wie beispielswei­se in Fig. 5 gezeigt ist.Of course, a pair of terminals 10 "of the second embodiment described with reference to FIGS. 8 to 11 may have a common contact piece 16, as shown for example in FIG. 5.
