Description

Bekannt sind Einzelklemmen mit einem Klemmkörper, welcher rahmenförmig oder umlaufend geschlossen ausgebildet und aus einem elektrisch leitenden Material gefertigt ist, wobei an einer Außenseite des Klemmkörpers wenigstens ein Anschlusspin einstückig angeformt ist. Derartige Einzelklemmen sind bspw. in den noch nicht veröffentlichten Patentanmeldungen DE 10 2007 004 587 oder DE 10 2007 004 545 offenbart. Die dort beschriebenen Einzelklemmen weisen in einer Seite des Klemmkörpers eine Durchgangsbohrung mit einem Innengewinde auf, durch welche eine Klemmschraube in den Klemmkörper eingedreht werden kann, um einen ins Innere des Klemmkörpers geführten elektrischen Leiter klemmend zu halten und eine elektrisch leitende Verbindung zwischen dem elektrischen Leiter und einer mit dem Klemmkörper über den Anschlusspin elektrisch leitend verbundenen Leiterplatte zu erreichen. Durch die Klemmschraube ist jedoch das Anschließen des elektrischen Leiters in der Einzelklemme für den Benutzer vergleichsweise aufwändig.Single terminals are known with a clamping body, which is formed frame-shaped or circumferentially closed and made of an electrically conductive material, wherein at least one terminal pin is integrally formed on an outer side of the clamping body. Such individual terminals are, for example, in the not yet published patent applications DE 10 2007 004 587 or DE 10 2007 004 545 disclosed. The individual terminals described therein have a through bore with an internal thread in one side of the clamp body, through which a clamping screw can be screwed into the clamp body to clamp a guided inside the clamp body electrical conductor and an electrically conductive connection between the electrical conductor and to achieve a conductor plate electrically connected to the terminal body via the terminal pin. By the clamping screw, however, the connection of the electrical conductor in the single terminal for the user is relatively expensive.

Die Aufgabe der Erfindung besteht daher darin, eine Einzelklemme bereitzustellen, welche einfach aufgebaut und benutzerfreundlich ist.The object of the invention is to provide a single terminal, which is simple and user-friendly.

Die Aufgabe der Erfindung wird gelöst durch eine Einzelklemme mit den Merkmalen des Patentanspruchs 1.The object of the invention is achieved by a single terminal having the features of patent claim 1.

Die Klemmfeder ist dabei derart angeordnet, dass ein anzuschließender elektrischer Leiter gegen die Federwirkung der Klemmfeder in den Klemmkörper eingeschoben werden kann und zwischen der Klemmfeder und dem Klemmkörper klemmend gehalten wird. Gleichzeitig stellt die Klemmfeder den elektrisch leitenden Kontakt zwischen dem elektrischen Leiter und dem Klemmkörper sicher. Der Anschluss eines elektrischen Leiters in einer derartigen Einzelklemme ist wesentlich zügiger durchzuführen, da der elektrische Leiter lediglich gegen die Federwirkung eingeschoben werden muss und nicht aufwändig zu verschrauben ist.The individual terminal according to the invention has a clamping body, which is frame-shaped and made of an electrically conductive material, wherein arranged on an outer side of the clamping body at least one connection pin, in particular integrally formed, and wherein according to the invention in the clamping body, a clamping spring is inserted.

Diese Struktur ist vorzugsweise in dem Auflageschenkel der Klemmfeder angeordnet, da dieser bereits eine großflächige Kontaktfläche zu dem Klemmkörper aufweist.The clamping spring is preferably caulked in the clamping body, embossed, welded, riveted or soldered to prevent the clamping spring from slipping in the clamping body or even detached from the clamping body. Preferably, at least for fixing the clamping spring in the clamping body to the clamping body arranged an element which fixes the applied clamping spring after folding or deformation. In a further preferred embodiment, the clamping spring has a structure with which it positively engages in a correspondingly shaped structure of the clamping body in order to prevent loosening or slipping of the clamping spring in the clamping body. This structure is preferably arranged in the support leg of the clamping spring, since this already has a large-area contact surface to the clamping body.

Die Figuren 1a und 1b zeigen ein erstes Ausführungsbeispiel einer Einzelklemme 10 mit einem Klemmkörper 20 und einer Klemmfeder 30. Der Klemmkörper 20 ist rahmenförmig ausgebildet. Dies bedeutet, dass der Klemmkörper 20 umlaufend geschlossen ausgebildet ist. Der Klemmkörper 20 weist Oberseite 21, eine parallel dazu angeordnete Unterseite 22 und zwei senkrecht dazu verlaufende, die Oberseite 21 und die Unterseite 22 verbindende Seitenflächen 23, 24 auf, welche einen Innenraum 26 umschließen, wobei der Innenraum 26 somit eine Durchgangsöffnung durch den Klemmkörper 20 bildet. Auf der nach außen gewandten Fläche der Unterseite 22 sind zwei Anschlusspins 27 angeordnet.The FIGS. 1a and 1b show a first embodiment of a single terminal 10 with a clamping body 20 and a clamping spring 30. The clamping body 20 is formed like a frame. This means that the clamping body 20 is formed circumferentially closed. The clamping body 20 has upper side 21, a lower side 22 arranged parallel thereto, and two side surfaces 23, 24 which extend perpendicularly thereto and connect the upper side 21 and the lower side 22, which has an inner space 26 enclose, wherein the interior 26 thus forms a passage opening through the clamping body 20. On the outward facing surface of the bottom 22, two connection pins 27 are arranged.

Der Klemmkörper 20 ist einstückig ausgebildet und kann bspw. durch spanabhebende Prozesse an einem Massivmaterialblock hergestellt werden. Der Klemmkörper 20 besteht aus einem elektrisch leitenden Material, bspw. aus Messing. Die Oberseite 21, die Unterseite 22 sowie die beiden Seitenflächen 23, 24 haben jeweils eine Wandstärke von mindestens 0,5 mm, vorzugsweise von mehr als 1 mm. Die Einzelklemme 10 weist kein isolierendes Gehäuse auf.The clamping body 20 is formed in one piece and can, for example, be produced by cutting processes on a block of solid material. The clamping body 20 is made of an electrically conductive material, for example. Of brass. The top 21, the bottom 22 and the two side surfaces 23, 24 each have a wall thickness of at least 0.5 mm, preferably more than 1 mm. The single terminal 10 has no insulating housing.

In den Innenraum 26 des Klemmkörpers 20 ist die Klemmfeder 30 eingesetzt. Die Klemmfeder 30 ist dabei insbesondere als Blattfeder ausgebildet. Die Klemmfeder 30 weist einen Auflageschenkel 32 und einen Klemmschenkel 34 auf, wobei der zwischen dem Auflageschenkel 32 und dem Klemmschenkel 34 eingeschlossene Winkel kleiner als 90° ist. Der Auflageschenkel 32 liegt, wie insbesondere in Figur 1b ersichtlich, an der Innenfläche der Oberseite 21 des Klemmkörpers 20 an. Aufgrund des zwischen dem Auflageschenkel 32 und dem Klemmschenkel 34 eingeschlossenen Winkels von weniger als 90° ragt der Klemmschenkel 34 in den Innenraum 26 und durchquert diesen ausgehend von der Oberseite 21 derart, dass ein freies Ende 34a des Klemmschenkels 34 auf der Innenfläche der Unterseite 22 zu liegen kommt. Damit die Klemmfeder 30 in dem Klemmkörper 20 fixiert ist, werden die beiden Seitenflächen 23, 24 nach Einsetzen der Klemmfeder 30 gegeneinander verprägt.In the interior 26 of the clamping body 20, the clamping spring 30 is inserted. The clamping spring 30 is formed in particular as a leaf spring. The clamping spring 30 has a support leg 32 and a clamping leg 34, wherein the included between the support leg 32 and the clamping leg 34 angle is less than 90 °. The support leg 32 is, as in particular in FIG. 1b can be seen on the inner surface of the top 21 of the clamp body 20 at. Due to the included between the support leg 32 and the clamping leg 34 angle of less than 90 ° of the clamping leg 34 projects into the interior 26 and traverses this starting from the top 21 such that a free end 34a of the clamping leg 34 on the inner surface of the bottom 22 to lie comes. So that the clamping spring 30 is fixed in the clamping body 20, the two side surfaces 23, 24 are stamped against each other after insertion of the clamping spring 30.

Um einen elektrischen Leiter an der Einzelklemme 10 anzuschließen, wird der elektrische Leiter mit seinem freien, abisolierten Ende in den Innenraum 26 des Klemmkörpers 20 derart geschoben, dass der Klemmschenkel 34 gegen seine Federwirkung gegen den Auflageschenkel 32 geschwenkt wird, wobei insbesondere der zwischen dem Auflageschenkel 32 und dem Klemmschenkel 34 eingeschlossene Winkel verkleinert wird. Die Federwirkung des Klemmschenkels 34 drückt dabei den elektrischen Leiter gegen die Innenseite der Unterseite 22 des Klemmkörpers 20, sodass der elektrische Leiter zwischen dem freien Ende 34a der Klemmfeder 30 und der Unterseite 22 klemmend gehalten wird. Über den elektrisch leitenden Klemmkörper 20 kann somit ein elektrisch leitender Kontakt zwischen dem elektrischen Leiter und den Anschlusspins 27, welche bspw. in elektrisch leitendem Kontakt mit Leiterbahnen einer Leiterplatte stehen, hergestellt werden. Der elektrisch leitende Kontakt zwischen dem elektrischen Leiter und dem Klemmkörper 20 wird weiter verbessert, wenn auch die Klemmfeder 30 aus einem elektrisch leitenden Material gefertigt ist.To connect an electrical conductor to the single terminal 10, the electrical conductor with its free, stripped End pushed into the interior 26 of the clamp body 20 such that the clamping leg 34 is pivoted against its spring action against the support leg 32, wherein in particular the enclosed between the support leg 32 and the clamping leg 34 angle is reduced. The spring action of the clamping leg 34 presses the electrical conductor against the inside of the underside 22 of the clamping body 20, so that the electrical conductor between the free end 34a of the clamping spring 30 and the bottom 22 is clamped. An electrically conductive contact between the electrical conductor and the connection pins 27, which, for example, are in electrically conductive contact with conductor tracks of a printed circuit board, can thus be produced via the electrically conductive clamping body 20. The electrically conductive contact between the electrical conductor and the clamping body 20 is further improved, although the clamping spring 30 is made of an electrically conductive material.

An die Einzelklemme 10 kann lediglich ein einziger elektrischer Leiter angeschlossen werden.To the single terminal 10, only a single electrical conductor can be connected.

Durch die Verwendung der Klemmfeder 30 wird das Anschließen eines elektrischen Leiters an die Einzelklemme 10 deutlich vereinfacht.By using the clamping spring 30, the connection of an electrical conductor to the single terminal 10 is significantly simplified.

In den Figuren 2a und 2b ist ein zweites Ausführungsbeispiel der Einzelklemme 10 dargestellt. Der Klemmkörper 20 des zweiten Ausführungsbeispiels der Einzelklemme 10 unterscheidet sich von dem in den Figuren 1a und 1b dargestellten ersten Ausführungsbeispiel dadurch, dass die Seitenflächen 23, 24 über die Oberseite 21 hinaus in jeweils einem Steg 40 verlängert ausgebildet sind. Die Klemmfeder 30 ist derart in den Klemmkörper 20 eingesetzt, dass der Auflageschenkel 32 mit seiner dem Klemmschenkel 34 zugewandten Innenfläche auf der Außenfläche der Oberseite 21 des Klemmkörpers 20 aufliegt und der Klemmschenkel 34 um die Oberseite 21 herumgreift, um in den Innenraum 26 hineinragen zu können. Die Oberseite 21 bildet somit einen Anschlag beim Einschieben der Klemmfeder 30 in den Klemmkörper 20 und verhindert ein Herausrutschen der Klemmfeder 30 in eine Richtung. Die Klemmfeder 30 kann insbesondere dadurch fixiert werden, dass die Stege 40 nach Einsetzen der Klemmfeder 30 in den Klemmkörper 20 wie in Figur 2b dargestellt nach innen auf die Oberseite 21 umgeformt oder umgelegt werden, um auf diese Weise den Auflageschenkel 32 der Klemmfeder 30 zu fixieren. Der Auflageschenkel 32 wird dabei klemmend zwischen den umgelegten Stegen 40 und der Außenfläche der Oberseite 21 des Klemmkörpers 20 gehalten.In the FIGS. 2a and 2b a second embodiment of the single terminal 10 is shown. The clamping body 20 of the second embodiment of the single terminal 10 differs from that in the FIGS. 1a and 1b illustrated first embodiment, characterized in that the side surfaces 23, 24 are formed over the top 21 out in each case a web 40 extended. The clamping spring 30 is inserted into the clamping body 20 such that the support leg 32 with his the clamping leg 34 facing inner surface rests on the outer surface of the upper side 21 of the clamping body 20 and the clamping leg 34 engages around the top 21 to project into the interior 26 can. The top 21 thus forms a stop when inserting the clamping spring 30 in the clamping body 20 and prevents slipping out of the clamping spring 30 in one direction. The clamping spring 30 can be fixed in particular in that the webs 40 after insertion of the clamping spring 30 in the clamping body 20 as in FIG. 2b shown inwardly formed on the top 21 or folded, in order to fix the support leg 32 of the clamping spring 30 in this way. The support leg 32 is held by clamping between the folded webs 40 and the outer surface of the upper side 21 of the clamping body 20.

Figur 3 zeigt ein drittes Ausführungsbeispiel der Einzelklemme 10, deren Klemmkörper 20 sich von dem Klemmkörper 20 des in den Figuren 1a und 1b dargestellten ersten Ausführungsbeispiels dadurch unterscheidet, dass die Seitenflächen 23, 24 ebenfalls über die Oberseite 21 hinaus in Stegen 50 verlängert sind, wobei jedoch an den freien Enden der Stege 50 jeweils ein Vorsprung 52 an den einander zugewandten Flächen der Seitenflächen 23, 24 angeordnet ist, sodass an jedem Steg 50 ein Hinterschnitt 54 gebildet wird. Die beiden Hinterschnitte 54 bilden eine Art von Führungsschiene, zwischen denen der Auflageschenkel 32 auf der Oberseite 21 derart eingeschoben werden kann, dass die dem Klemmschenkel 34 zugewandte Fläche des Auflageschenkels 32 auf der Außenseite der Oberseite 21 zu liegen kommt, während der Klemmschenkel 34 um die Oberseite 21 herumgreifend in den Innenraum 26 geführt ist. Zum Fixieren der Klemmfeder 30 können die Vorsprünge 52 derart umgeformt werden, dass sie auf die Klemmfeder 30 gedrückt werden, um den Auflageschenkel 32 klemmend zwischen den Vorsprüngen 52 und der Oberseite 21 des Klemmkörpers 20 zu halten. FIG. 3 shows a third embodiment of the single terminal 10, the clamping body 20 of the clamping body 20 of the in the FIGS. 1a and 1b differs in that the side surfaces 23, 24 are also extended beyond the top 21 out in webs 50, but at the free ends of the webs 50 each have a projection 52 is disposed on the mutually facing surfaces of the side surfaces 23, 24, so that an undercut 54 is formed on each web 50. The two undercuts 54 form a type of guide rail, between which the support leg 32 can be inserted on the top 21 such that the clamping leg 34 facing surface of the support leg 32 comes to rest on the outside of the top 21, while the clamping leg 34 to the Top 21 around around in the interior 26 is guided. To fix the clamping spring 30, the projections 52 can be deformed so that they are pressed onto the clamping spring 30 to the Support leg 32 clamped between the projections 52 and the top 21 of the clamp body 20 to keep.

Figur 4 zeigt ein viertes Ausführungsbeispiel der Einzelklemme 10, welches sich von dem in Figur 3 dargestellten dritten Ausführungsbeispiel dadurch unterscheidet, dass lediglich eine der beiden Seitenflächen 23, 24, vorliegend die Seitenfläche 23, über die Oberseite 21 hinaus in einen Steg 60 verlängert ist, wobei an dem freien Ende des Steges 60 im Wesentlichen rechtwinklig ein Vorsprung 62 angeordnet ist, der nahezu dieselbe Fläche aufweist wie die Oberseite 21, sodass zwischen dem Vorsprung 62 und der Oberseite 21 des Klemmkörpers 20 ein Führungsschlitz 64 gebildet ist, in welchen der Auflageschenkel 32 der Klemmfeder 30 eingeschoben werden kann. Der Klemmschenkel 34 der Klemmfeder 30 greift wiederum um die Oberseite 21 herum in den Innenraum 26 des Klemmkörpers 20. Zum endgültigen Fixieren der Klemmfeder 30 an dem Klemmkörper 20 kann wiederum der Vorsprung 62 derart umgeformt oder umgebogen werden, dass er in Richtung auf den Auflageschenkel 32 der Klemmfeder 30 gedrückt wird und somit den Auflageschenkel 32 klemmend fixiert. FIG. 4 shows a fourth embodiment of the single terminal 10, which differs from the in FIG. 3 3, characterized in that only one of the two side surfaces 23, 24, in this case the side surface 23, is extended beyond the upper side 21 into a web 60, wherein at the free end of the web 60 a projection 62 is arranged substantially at right angles. which has almost the same surface as the top 21, so that between the projection 62 and the top 21 of the clamp body 20, a guide slot 64 is formed, in which the support leg 32 of the clamping spring 30 can be inserted. The clamping leg 34 of the clamping spring 30 in turn engages around the upper side 21 in the interior 26 of the clamping body 20. For final fixing of the clamping spring 30 to the clamping body 20, in turn, the projection 62 can be deformed or bent in such a way that it towards the support leg 32nd the clamping spring 30 is pressed and thus fixed the support leg 32 by clamping.

Figur 5 zeigt ein fünftes Ausführungsbeispiel der Einzelklemme 10. Die Klemmfeder 30 ist dabei derart an dem Klemmkörper 20 angeordnet, dass nicht wie in dem in den Figuren 1a und 1b dargestellten ersten Ausführungsbeispiel die dem Klemmschenkel 34 abgewandte Fläche des Auflageschenkels 32 an der Innenfläche der Oberseite 21 anliegt, sondern dass die dem Klemmschenkel zugewandte Fläche des Auflageschenkels 32 der Klemmfeder 30 auf der Außenseite der Oberfläche 21 anliegt. Zur Fixierung der Klemmfeder 30 an dem Klemmkörper 20 weist die Klemmfeder 30 in dem Auflageschenkel 32 einen Schweiß- oder Lötpunkt 70 auf. FIG. 5 shows a fifth embodiment of the single terminal 10. The clamping spring 30 is arranged on the clamp body 20, that not as in the in the FIGS. 1a and 1b shown first embodiment, the clamping leg 34 facing away from the surface of the support leg 32 rests against the inner surface of the top 21, but that the clamping leg facing surface of the support leg 32 of the clamping spring 30 rests on the outside of the surface 21. For fixing the clamping spring 30 to the clamping body 20, the clamping spring 30 in the support leg 32 has a welding or soldering point 70.

Das in Figur 6 dargestellte sechste Ausführungsbeispiel der Einzelklemme 10 unterscheidet sich von dem in Figur 5 dargestellten fünften Ausführungsbeispiel dadurch, dass statt eines Schweiß- oder Lötpunkts die Klemmfeder 30 an dem Klemmkörper 20 vernietet wird. Dazu ist an der Außenfläche der Oberseite 21 des Klemmkörpers 20 eine Struktur, insbesondere ein Nietzapfen 80 angeordnet, welcher in eine korrespondierende Struktur des Auflageschenkels 32, insbesondere eine Bohrung 82 entsprechend eingreift. Nach Einhängen der Klemmfeder 30 über die Bohrung 82 an dem Nietzapfen 80 erfolgt die Fixierung der Klemmfeder 30 an dem Klemmkörper 20 über ein Vernieten. Die korrespondierenden Strukturen zwischen dem Klemmkörper 20 und der Klemmfeder 30 können weiterhin auch verschiedene formschlüssig ineinander greifende Strukturen oder Rastmechanismen sein, über welche die Klemmfeder 30 an dem Klemmkörper 20 fixiert werden kann. Insbesondere können diese Strukturen auch auf der Innenseite der Oberseite 21 des Klemmkörpers 20 sowie der dem Klemmschenkel 34 abgewandten Fläche des Auflageschenkels 32 der Klemmfeder 30 angeordnet sein, um die Klemmfeder 30 an dem Klemmkörper 20 zu fixieren.This in FIG. 6 illustrated sixth embodiment of the single terminal 10 differs from that in FIG. 5 illustrated fifth embodiment in that instead of a welding or soldering point, the clamping spring 30 is riveted to the clamping body 20. For this purpose, a structure, in particular a rivet peg 80 is arranged on the outer surface of the upper side 21 of the clamping body 20, which engages in a corresponding structure of the support leg 32, in particular a bore 82 accordingly. After hanging the clamping spring 30 via the bore 82 on the rivet pin 80, the fixing of the clamping spring 30 to the clamping body 20 via a riveting. The corresponding structures between the clamping body 20 and the clamping spring 30 may also be various interlocking interlocking structures or locking mechanisms, via which the clamping spring 30 can be fixed to the clamping body 20. In particular, these structures can also be arranged on the inside of the upper side 21 of the clamping body 20 and the clamping leg 34 facing away from the surface of the support leg 32 of the clamping spring 30 to fix the clamping spring 30 to the clamping body 20.

In den Figuren 7a, 7b und 7c ist ein siebtes Ausführungsbeispiel der Einzelklemme 10 dargestellt, deren Klemmkörper 20 sich von dem Klemmkörper 20 des in den Figuren 1a und 1b dargestellten ersten Ausführungsbeispiels dadurch unterscheidet, dass an den Seitenkanten der Seitenflächen 23, 24 in Richtung parallel zu den Seitenflächen 23, 24 und parallel zu der Oberseite 21 an jeder der Seitenflächen 23, 24 ein Steg 90 angeordnet ist, welcher insbesondere nach vorn, d. h. entlang der Einführrichtung eines anzuschließenden elektrischen Leiters hervorragt, und der in einem ersten Umfang- oder Prägeprozess jeweils auf den anderen Steg zu umgebogen wird, wodurch sich beim Einschieben der Klemmfeder 30 derart, dass die dem Klemmschenkel 34 abgewandte Fläche des Auflageschenkels 32 an der Innenseite der Oberseite 21 des Klemmkörpers 20 zu liegen kommt, ein Einschubanschlag für die Klemmfeder 30 ergibt. Die beiden umgebogenen Stege 90 werden von dem Klemmschenkel 34 derart umgriffen, dass anschließend der Klemmschenkel 34 in den Innenraum 26 des Klemmkörpers 20 hineinragt, wie insbesondere in Figur 7c ersichtlich. Ein Fixieren der Klemmfeder 30 kann durch Verprägen der Seitenflächen 23, 24 erfolgen.In the Figures 7a, 7b and 7c a seventh embodiment of the single terminal 10 is shown, the clamping body 20 of the clamping body 20 of the in the FIGS. 1a and 1b 1, characterized in that at the side edges of the side surfaces 23, 24 in the direction parallel to the side surfaces 23, 24 and parallel to the top 21 on each of the side surfaces 23, 24, a web 90 is arranged, which in particular forward, ie along the insertion direction of an electrical conductor to be connected protrudes, and which in a first circumferential or embossing process in each case to the other web to be bent, whereby during insertion of the clamping spring 30 such that the clamping leg 34 facing away from the surface of the support leg 32 comes to rest on the inside of the top 21 of the clamping body 20, a slot stop for the clamping spring 30 results. The two bent webs 90 are encompassed by the clamping leg 34 such that subsequently the clamping leg 34 projects into the interior 26 of the clamping body 20, in particular in FIG. 7c seen. A fixing of the clamping spring 30 can be done by stamping the side surfaces 23, 24.

In den Figuren 8a und 8b ist ein achtes Ausführungsbeispiel der Einzelklemme 10 dargestellt, wobei der Klemmkörper 20 identisch zu dem Klemmkörper 20 des in den Figuren 1a und 1b dargestellten ersten Ausführungsbeispiels ausgebildet ist, die Klemmfeder 30 jedoch wiederum derart an dem Klemmkörper 20 angeordnet ist, dass die dem Klemmschenkel 34 zugewandte Fläche des Auflageschenkels 32 auf der Außenfläche der Oberseite 21 des Klemmkörpers 20 angeordnet ist. Die Klemmfeder 30 weist dabei zusätzlich eine aus dem Klemmschenkel 34 herausgebogene, in Richtung auf den Auflageschenkel 32 aufgebogene Lasche 102 auf, die auf der Innenfläche der Oberseite 21 anliegt, während der Auflageschenkel 32 ein in Richtung auf den Klemmschenkel 34 abgebogenes freies Ende 100 aufweist, welches über die Oberseite 21 hinüberragt, so dass die Klemmfeder 30 über das freie Ende 100 und die Lasche 102 klemmend an der Oberseite 21 fixiert werden kann.In the FIGS. 8a and 8b an eighth embodiment of the single terminal 10 is shown, wherein the clamping body 20 identical to the clamping body 20 of the in FIGS. 1a and 1b However, the clamping spring 30 is in turn arranged on the clamping body 20 such that the clamping leg 34 facing surface of the support leg 32 is disposed on the outer surface of the upper side 21 of the clamping body 20. The clamping spring 30 in this case additionally has a bent out of the clamping leg 34, in the direction of the support leg 32 straightened tab 102 which rests on the inner surface of the top 21, while the support leg 32 has a bent toward the clamping leg 34 free end 100, which protrudes beyond the upper side 21, so that the clamping spring 30 can be fixed in a clamping manner on the upper side 21 via the free end 100 and the tab 102.

In den Figuren 9a und 9b ist ein neuntes Ausführungsbeispiel einer Einzelklemme 110 mit einem Klemmkörper 120 und einer Klemmfeder 130 dargestellt. Der Klemmkörper 120 ist rahmenförmig, d. h. umlaufend geschlossen ausgebildet. Der Klemmkörper 120 weist eine Oberseite 121, einer parallel dazu angeordnete Unterseite 122 und zwei senkrecht dazu verlaufende, die Oberseite 121 und die Unterseite 122 verbindende Seitenflächen 123, 124 auf. Auf der nach außen gewandten Fläche der Unterseite 212 sind zwei Anschlusspins 127 angeordnet. Der Klemmkörper 120 ist einstückig ausgebildet und kann bspw. durch spanabhebende Prozesse an einem Massivmaterialblock hergestellt werden. Der Klemmkörper 120 besteht aus einem elektrisch leitenden Material, bspw. aus Messing. Die Oberseite 121, die Unterseite 122 sowie die beiden Seitenflächen 123, 24 haben jeweils eine Wandstärke von mindestens 0,5 mm, vorzugsweise von mehr als 1 mm. Die Einzelklemme 110 weist kein isolierendes Gehäuse auf.In the FIGS. 9a and 9b a ninth embodiment of a single terminal 110 with a clamping body 120 and a clamping spring 130 is shown. The clamping body 120 is frame-shaped, ie formed circumferentially closed. The clamping body 120 has an upper side 121, a lower side 122 arranged parallel thereto, and two perpendicularly extending ones, the upper side 121 and the bottom 122 connecting side surfaces 123, 124 on. On the outward facing surface of the bottom 212, two connection pins 127 are arranged. The clamping body 120 is formed in one piece and can be produced, for example, by cutting processes on a block of solid material. The clamping body 120 consists of an electrically conductive material, for example. Of brass. The top 121, the bottom 122 and the two side surfaces 123, 24 each have a wall thickness of at least 0.5 mm, preferably more than 1 mm. The single terminal 110 does not have an insulating housing.

Zwischen der Oberseite 121 und der Unterseite 122 ist ein Zwischenboden 125 angeordnet, so dass zwischen der Oberseite 121 und dem Zwischenboden 125 ein erster Innenraum 126a und zwischen dem Zwischenboden 125 und der Unterseite 122 ein zweiter Innenraum 126b gebildet ist. Beide Innenräume 126a, 126b bilden jeweils eine Durchgangsöffnung durch den Klemmkörper 120.Between the upper side 121 and the lower side 122, an intermediate floor 125 is arranged, so that a first inner space 126a is formed between the upper side 121 and the intermediate floor 125 and a second inner space 126b is formed between the intermediate floor 125 and the lower side 122. Both interior spaces 126a, 126b each form a passage opening through the clamp body 120.

In den ersten Innenraum 126a ist die Klemmfeder 130 eingesetzt, welche vorliegend als Käfigzugfeder ausgebildet ist. Die Klemmfeder 130 weist einen Auflageschenkel 132 und einen Klemmschenkel 134 auf, die an einem Ende miteinander verbunden sind, sodass der Auflageschenkel 132 ein freies Ende 132a und der Klemmschenkel 134 ein freies Ende 134a aufweist. Der Klemmschenkel 134 weist in seinem freien Ende 134a einen Durchbruch 135 auf, durch den das freie Ende 132a des Auflageschenkels 132 hindurchgreift.In the first interior 126a, the clamping spring 130 is inserted, which is in the present case designed as a cage tension spring. The clamping spring 130 has a support leg 132 and a clamping leg 134, which are connected together at one end, so that the support leg 132 has a free end 132a and the clamping leg 134 has a free end 134a. The clamping leg 134 has an opening 135 in its free end 134a, through which the free end 132a of the support leg 132 engages.

Der Auflageschenkel 132 liegt mit seiner Außenfläche auf der der Oberseite 121 zugewandten Fläche des Zwischenbodens 125 auf. Der Klemmschenkel 134 durchquert den ersten Innenraum 126a bis zur Innenfläche der Oberseite 121, wobei er dort jedoch in der Regel lediglich dann anliegt, wenn kein elektrischer Leiter angeschlossen ist. Ausgehend von der Innenfläche der Oberseite 121 des Klemmkörpers verläuft der Klemmschenkel 134 zurück in Richtung auf den Zwischenboden 125, wo sein Durchbruch von dem Auflageschenkel 132 durchsetzt wird. Zusätzlich zu dem freien Ende 132a des Auflageschenkels 132 durchsetzt auch der Zwischenboden 125, der nach vorne über die Oberseite 121 und die Unterseite 122 hervorsteht, den Durchbruch 125 des freien Endes 134a des Klemmschenkels 134.The support leg 132 rests with its outer surface on the surface 121 of the intermediate bottom 125 facing the upper side. The clamping leg 134 passes through the first inner space 126 a to the inner surface of the upper side 121, but there usually only applied when no electrical conductor is connected. Starting from the inner surface of the upper side 121 of the clamping body, the clamping leg 134 extends back in the direction of the intermediate bottom 125, where its breakthrough is penetrated by the support leg 132. In addition to the free end 132 a of the support leg 132 and the intermediate bottom 125, which protrudes forward over the top 121 and the bottom 122 passes through the opening 125 of the free end 134 a of the clamping leg 134th

Die Klemmfeder 30 kann in dem Klemmkörper 20 beispielsweise durch Verprägen der Seitenflächen 123, 24 oder durch andere der zuvor genannte Fixiermechanismen befestigt werden.The clamping spring 30 can be fixed in the clamping body 20, for example by stamping the side surfaces 123, 24 or by other of the aforementioned fixing mechanisms.

Zum Anschließen eines elektrischen Leiters wird der Klemmschenkel 134 in Richtung auf die Unterseite 122 derart gedrückt, dass der Durchbruch 135 vor dem zweiten Innenraum 126b liegt und der elektrische Leiter durch den Durchbruch 135 in den zweiten Innenraum 126b des Klemmkörpers 120 eingeführt werden kann. Wird die Klemmfeder 130 entspannt, zieht der Klemmschenkel 134 den elektrischen Leiter über den Durchbruch 135 gegen die der Unterseite 122 zugewandte Fläche des Zwischenbodens 125, so dass auf diese Weise ein elektrisch leitender Kontakt zwischen dem elektrischen Leiter und dem Klemmkörper 120 hergestellt wird. An die Einzelklemme 110 kann lediglich ein einziger elektrischer Leiter angeschlossen werden.To connect an electrical conductor, the clamping leg 134 is pressed in the direction of the underside 122 in such a way that the opening 135 lies in front of the second internal space 126b and the electrical conductor can be inserted through the opening 135 into the second internal space 126b of the clamping body 120. If the clamping spring 130 is relaxed, the clamping leg 134 pulls the electrical conductor via the opening 135 against the underside 122 facing surface of the intermediate bottom 125, so that in this way an electrically conductive contact between the electrical conductor and the clamping body 120 is produced. To the single terminal 110, only a single electrical conductor can be connected.

Die verschiedenen Klemmfederarten und Fixiermechanismen der Klemmfedern sowie die verschiedenen Ausgestaltungen der Klemmkörper können selbstverständlich beliebig miteinander kombiniert werden.The various clamping spring types and fixing mechanisms of the clamping springs and the various embodiments of the clamping body can of course be combined with each other.
