Description

Die Erfindung bezieht sich auf eine elektrische Klemme, deren Klemmkörper in Falttechnik aus Schenkeln beidseits zu einem Rücken gebildet wird, der eine Klemmschraube führt. Derartige Klemmen werden bei Reihenklemmen, als Installationsklemmen, in elektrischen Geräten oder in Verteilungen und zum Anschließen an Stromschienen verwendet. Sie sollen wirtschaftlich zu fer­tigen sein und dennoch dauerhaft guten elektrischen Kontakt sicherstellen.The invention relates to an electrical clamp, the clamping body of which is formed by folding from legs on both sides to a back which guides a clamping screw. Such terminals are used in terminal blocks, as installation terminals, in electrical devices or in distributors and for connection to busbars. They should be economical to manufacture and still ensure good electrical contact over the long term.

Um derartige Klemmen aus Bandmaterial herzustellen, wird auf die vielfältigste Weise vorgegangen (beispielsweise nach DE-PS 890 087 oder DE-0S 2 915 575). Hierbei werden Teile ver­schweißt oder in Stecktechnik miteinander verbunden, wobei auch die verschiedenartigsten Faltungen bekannt sind. Besonders kri­tisch ist die Verbindung von Enden bandförmigen Materials, wenn sie nicht aufwendig verschweißt werden sollen und wenn man mit verhältnismäßig dünnem Material auskommen möchte. Empfindlich ist ein Klemmkörper aus dünnem Material besonders dann, wenn der Klemmkörper von seiner Funktion her seine Wandteile auf Zug beansprucht, wenn es also nicht genügt, schellenartige Teile miteinander zu verschrauben.In order to produce such clips from strip material, the most varied of procedures are used (for example according to DE-PS 890 087 or DE-0S 2 915 575). In this case, parts are welded or connected to one another using plug-in technology, and the most diverse folds are also known. The connection of ends of band-shaped material is particularly critical if they are not to be welded in a complex manner and if one wants to get by with relatively thin material. A clamp body made of thin material is particularly sensitive when the function of the clamp body places its wall parts under tension, so when it is not sufficient to screw clamp-like parts together.

Der Erfindung liegt die Aufgabe zu Grunde, eine elektrische Klemme zu entwickeln, die stabil ist und die sich einfach und wirtschaftlich fertigen läßt. Die Lösung der geschilderten Auf­gabe besteht nach der Erfindung darin, daß ein Schenkel zumin­dest ein Durchsteckfenster aufweist, durch das eine Zunge des anderen Schenkels gesteckt wird, wodurch dieser Schenkel den Klemmenboden bildet, wobei an diesem Schenkel seitlich T-för­mige, hinterschnittene Lappen überstehen, die unter dem unter­halb des Bodens umgelegten Ende des Schenkels, der das Durch­ steckfenster aufweist, mit ihren freigeschnittenen Enden ein­gebogen sind. Dadurch entsteht ein Klemmkörper mit besonders stabilem Boden.The invention is based on the object of developing an electrical terminal which is stable and which can be manufactured simply and economically. The solution to the described problem is according to the invention that one leg has at least one push-through window through which a tongue of the other leg is inserted, whereby this leg forms the terminal base, T-shaped, undercut tabs projecting laterally on this leg, which under the end of the leg folded over below the floor, which the through has window, are bent with their cut ends. This creates a sprag with a particularly stable base.

Wenn die T-förmigen Lappen einen auseinanderlaufenden Halsbe­reich, bildlich der T-Stiel, und daran nach außen zu eingewin­kelte Enden bilden, die, gegen den Hals umgebogen, bildlich an schiefen Angeln hängen, werden beim Umbiegen der Enden Ferti­gungstoleranzen eliminiert. Die Enden gelangen beim Umbiegen nämlich zu einer Position, wo sie am Boden des Klemmkörpers aufreiten.If the T-shaped tabs form a diverging neck area, figuratively the T-stem, and thereon outwardly angled ends which, bent against the neck, hang figuratively on crooked hinges, manufacturing tolerances are eliminated when the ends are bent. When bending, the ends come to a position where they spread out at the bottom of the sprag.

Wenn unter dem Rücken ein stärkeres Führungsstück für die Klemm­schraube eingesetzt ist, das mit seitlichen Nasen in Fenstern in beiden Schenkeln eingesteckt ist, erzielt man eine Klemme mit mehreren Vorteilen: So kann einmal durch ein Stanzteil aus einem Material mit den gewünschten Eigenschaften ein besonders stabiles Gewinde als Führung für die Klemmschraube erzielt wer­den. Andererseits erzielt man eine Bremse gegen Lockern der Klemmschraube und gegen Überdrehen beim Festklemmen eines Lei­ters. Ohne eine derartige Bremse könnte der Leiter mitunter zu stark gequetscht werden. Die Bremswirkung kommt dadurch zustan­de, daß nach Aufsetzen der Klemmschraube auf einem anzuklemmen­den Leiter beim Weiterdrehen der Rücken des Klemmkörpers sich vom stärkeren Führungsstück abhebt und dadurch zum Verkanten des Gewindes im Rückes des Klemmkörpers und zum Verspannen führt. Das stärkere Führungsstück kann in der Fertigung zu­gleich als Träger und zum Positionieren eines seitlich zuge­führten Bandmaterials für den Klemmkörper dienen.If a stronger guide piece for the clamping screw is inserted under the back, which is inserted with side lugs in windows in both legs, a clamp with several advantages is achieved: For example, a stamped part made of a material with the desired properties can be used to create a particularly stable thread can be achieved as a guide for the clamping screw. On the other hand, one achieves a brake against loosening the clamping screw and against overtightening when clamping a conductor. Without such a brake, the conductor could sometimes be squeezed too much. The braking effect arises from the fact that after the clamping screw is placed on a conductor to be clamped, when the turning of the clamping body continues, the back of the clamping body lifts off from the stronger guide piece, thereby causing the thread in the back of the clamping body to jam and cause tension. The stronger guide piece can also serve as a carrier in the production and for positioning a laterally fed strip material for the clamping body.

Es ist besonders vorteilhaft, wenn das Führungsstück zu Fenstern in den Schenkeln in seiner Führungsebene Spiel beläßt, so daß das Gewinde durch den Rücken des Klemmkörpers und das einge­setzte Führungsstück in einem Arbeitsgang durchgeschnitten wer­den kann. Das Führungsstück kann einen kreuzförmigen Grundriß aufweisen und einfach als Stanzteil hergestellt werden.It is particularly advantageous if the guide piece for windows in the legs leaves play in its guide plane, so that the thread can be cut through the back of the clamping body and the guide piece used in one operation. The guide piece can have a cruciform plan and can be easily produced as a stamped part.

Nach einer anderen Weiterbildung sind beide Schenkel oberhalb des zu bildenden Bodens in ihrer Breite zum Boden hin verjüngt ausgeführt. Wenn in einer derartigen Klemme ein anzuschließen­der elektrischer Leiter verformt und seitlich ausgequetscht wird, vermeidet man dennoch, daß sich der eingeführte Körper am Klemmkörper so verhaken könnte, daß er nicht ohne weiteres mehr zu entfernen wäre. Die vom Boden des Klemmkörpers nach oben wei­ter werdenden Flanken der den Klemmkörper bildenden Schenkel wir­ken dabei als Stütze, die um so stärker wirkt, je stärker der Leiter verquetscht würde.According to another development, both legs are tapered in their width towards the bottom above the base to be formed. If an electrical conductor to be connected is deformed and laterally squeezed out in such a clamp, one nevertheless avoids that the inserted body could get caught on the clamp body in such a way that it could not be easily removed. The flanks of the legs forming the clamping body, which flare upward from the bottom of the clamping body, act as a support which acts the more the more the conductor is squeezed.

Wenn der Boden des Klemmkörpers leicht V-förmig durchgebogen ist, was in der Praxis durch die Biegetechnik ohnehin mehr oder weniger stark eintritt, wird den Enden der T-förmigen Lappen in Abhängigkeit von der Neigung der "schiefen Angeln", eine defi­nierte Region für das Aufreiten geboten.If the bottom of the clamping body is slightly bent in a V-shape, which is more or less the case in practice due to the bending technique, the ends of the T-shaped tabs become a defined region for the depending on the inclination of the "crooked hinges" Riding on.

Der Klemmkörper wird besonder fest, wenn der durchgesteckte Lappen am Schenkel des Klemmkörpers hinter dem Fenster nach unten, zum Boden des Klemmkörpers, umgebogen ist. Der umgebo­gene Bereich des Lappens stabilisiert den Klemmkörper, wobei er in der Biegung des Bodenteils Platz findet, so daß die Klemme an ihren Flanken ohne vorspringende Teile plan sein kann.The clamp body becomes particularly firm when the inserted tab on the leg of the clamp body behind the window is bent downward toward the bottom of the clamp body. The bent area of the flap stabilizes the clamping body, whereby it finds space in the bend of the base part, so that the clamp can be flat on its flanks without projecting parts.

Die Erfindung soll nun an Hand von in der Zeichnung grob sche­matisch wiedergegebenen Ausführungsbeispielen näher erläutert werden:

  • In FIG 1 ist eine Klemme von vorn, also in Einführungsrichtung für einen festzuklemmenden Leiter, wiedergegeben.
  • In FIG 2 ist die Klemme nach FIG 1 in Seitenansicht darge­stellt.
  • In FIG 3 ist die Klemme nach FIG 1 von unten gesehen wiederge­geben.
  • In FIG 4 ist die Klemme nach FIG 2 bei herausgedrehter Klemm­schraube von oben gesehen veranschaulicht.
  • In FIG 5 ist ein Bandkörper dargestellt, der zur Klemme nach FIG 1 gefaltet werden kann.
The invention will now be explained in greater detail on the basis of exemplary embodiments shown roughly schematically in the drawing:
  • 1 shows a terminal from the front, that is in the direction of insertion for a conductor to be clamped.
  • In Figure 2, the terminal of Figure 1 is shown in side view.
  • In Figure 3, the terminal of Figure 1 is shown seen from below.
  • FIG. 4 illustrates the clamp according to FIG. 2 when the clamping screw is removed from above.
  • 5 shows a band body which can be folded into the clamp according to FIG. 1.

Die elektrische Klemme nach FIG 1 weist einen Klemmkörper 1 in Falttechnik auf, der aus Schenkeln 2, 3 beidseits zu einem Rük­ken 4 gebildet wird. Der Rücken führt eine Klemmschraube 5 in einem Gewinde im Rücken 4. Der Schenkel 2 weist ein Durchsteck­fenster 6 auf, durch das der andere Schenkel 3 mit einer Zunge 7 gesteckt ist. Der Schenkel 3, an dem die Zunge 7 aufgeführt ist, bildet dadurch den Klemmenboden 8. An diesem Schenkel 3 sind seitlich T-förmige, hinterschnittene Lappen 9, 10 überste­hend ausgeführt. Sie sind unter dem unterhalb des Bodens 8 um­gelegten Ende des Schenkels 2, der das Durchsteckfenster auf­weist, mit ihren freigeschnittenen Enden 12, 13 eingebogen. Sie bilden dadurch in Falttechnik den Boden des Klemmkörpers 1.The electrical clamp according to FIG. 1 has a clamp body 1 using folding technology, which is formed from legs 2, 3 on both sides to form a back 4. The back carries a clamping screw 5 in a thread in the back 4. The leg 2 has a push-through window 6 through which the other leg 3 is inserted with a tongue 7. The leg 3, on which the tongue 7 is listed, thereby forms the terminal base 8. On this leg 3, T-shaped, undercut tabs 9, 10 project laterally. They are bent in under the bottom 8 of the leg 2, which has the push-through window, with their cut-out ends 12, 13. As a result, they form the bottom of the clamping body 1 using folding technology.

Die T-förmigen Lappen 9, 10 weisen einen auseinanderlaufenden Halsbereich, bildlich der T-Stiel, und daran nach außen zu ein­gewinkelte Enden 12, 13 auf. Beim Umbiegen bilden sich dadurch schiefe Biegelinien, die hier bildhaft als schiefe Angeln 14, 15 bezeichnet werden sollen.The T-shaped tabs 9, 10 have a diverging neck region, figuratively the T-stem, and ends 12, 13 which are angled outward therefrom. When bending, oblique bending lines are formed, which are to be referred to as oblique hinges 14, 15.

Unter dem Rücken 4 ist im Ausführungsbeispiel nach FIG 1 ein stärkeres Führungsstück 16 für die Klemmschraube 5 eingesetzt. Hierzu weist das Führungsstück 16 seitliche Nasen 17 auf, die in Fenster 18 in beiden Schenkeln 2, 3 eingesetzt sind. Es ist vorteilhaft, Nasen und Fenster so aufeinander abzustimmen, daß in der Führungsebene, also senkrecht zu Zeichenebene für das Führungsstück 16 Spiel bleibt. Das Gewinde für die Klemmschrau­be 5 kann dann im Rücken 4 und im Führungsstück 16 trotz Fer­tigungstoleranzen in einem Arbeitsgang eingeschnitten werden. Das Führungsstück 16 kann vorteilhafterweise einen im wesentli­chen kreuzförmigen Grundriß aufweisen, wie es aus FIG 4 zu er­ sehen ist.In the exemplary embodiment according to FIG. 1, a stronger guide piece 16 for the clamping screw 5 is inserted under the back 4. For this purpose, the guide piece 16 has lateral lugs 17 which are inserted in window 18 in both legs 2, 3. It is advantageous to coordinate lugs and windows so that 16 remains in the guide plane, ie perpendicular to the plane of the drawing for the guide piece. The thread for the clamping screw 5 can then be cut in the back 4 and in the guide piece 16 despite manufacturing tolerances in one operation. The guide piece 16 can advantageously have an essentially cruciform plan, as is shown in FIG see is.

Im Ausführungsbeispiel sind beide Schenkel, der Schenkel 2 nach FIG 2 und der hinter der Zeichenebene liegende Schenkel 3 ober­halb des zu bildenden Klemmenbodens 8 in ihrer Breite zum Boden hin verjüngt. Dadurch wird das Verquetschen anzuschließender Leiter vermindert und insbesondere vermieden, daß sich überste­hende Leiter hinter den Schenkeln verhaken, so daß sie aus der Klemme nicht mehr ohne weiteres herzuziehen wären.In the exemplary embodiment, both legs, the leg 2 according to FIG. 2 and the leg 3 lying behind the plane of the drawing, are tapered in width towards the bottom above the terminal base 8 to be formed. This reduces the squeezing of the conductors to be connected and, in particular, prevents the protruding conductors from getting caught behind the legs, so that they would no longer be easy to pull out of the clamp.

Der Klemmenboden 8 ist vorteilhafterweise leicht V-förmig durchgebogen ausgeführt, wie es aus FIG 1 zu ersehen ist. Die Lappenenden 12 und 13 an den "schiefen Angeln" 14, 15 finden dann am Klemmenboden beim Umbiegen einen definierten Bereich, in dem sie am Boden aufreiten und den Klemmenkörper im Form­schluß besonders stabil werden lassen. Für einen festen Klemm­körper ist es auch vorteilhaft, wenn die durchgesteckte Zunge 7 hinter dem Durchsteckfenster 6 nach unten umgebogen ist, wie es in FIG 1 veranschaulicht ist.The terminal base 8 is advantageously slightly bent in a V-shape, as can be seen from FIG. 1. The flap ends 12 and 13 on the "crooked hinges" 14, 15 then find a defined area on the terminal base during bending, in which they spread out on the base and make the terminal body particularly stable in the form-fit. For a fixed clamping body, it is also advantageous if the inserted tongue 7 is bent downward behind the push-through window 6, as is illustrated in FIG. 1.

Wenn die Klemmschraube 5 gegen einen einzuklemmenden Leiter an­gezogen wird, hebt sich schließlich der Rücken 4 des Klemmkör­pers vom Führungsteil 16 zunehmend stark ab, so daß die Klemm­schraube gegen zu festen Anziehen eine Bremse im Sinne einer Drehmomentbremse aufweist. Sie schützt zugleich gegen Lockern.When the clamping screw 5 is tightened against a conductor to be clamped, the back 4 of the clamping body finally lifts off increasingly strongly from the guide part 16, so that the clamping screw has a brake in the sense of a torque brake against over-tightening. It also protects against loosening.

In FIG 5 ist ein Stanzteil wiedergegeben, aus dem eine Klemme nach den FIG 1 bis 4 in Biegetechnik hergestellt werden kann. Die Biegezogen sind schraffiert veranschaulicht. Im übrigen tragen gleiche Teile gleiche Bezugszeichen.5 shows a stamped part from which a clamp according to FIGS. 1 to 4 can be produced using bending technology. The bending pulls are shown hatched. Otherwise, the same parts have the same reference numerals.
