Daneben betrifft die Erfindung auch ein metallisches Schutzleiteranschlußelement mit einem mindestens eine Befestigungsausnehmung zur Aufnahme eines Schenkels einer Tragschiene aufweisenden, als flacher, schmaler Metallstreifen ausgefiihren Metallfuß und mit einer mit dem Metallfuß verbundenen, einen Schenkel der Tragschiene elektrisch kontaktierenden Auflagefeder zur Verwendung in einer elektrischen Reihenklemme.The invention relates to an electrical terminal for placing on a Support rail with preferably two legs, with a made of insulating material Terminal housing and arranged with one in the foot of the terminal housing metallic protective conductor connection element, wherein the clamping housing at least one protective conductor terminal, and preferably two Outer conductor passage terminals and wherein the protective conductor terminal an at least partially extending over the mounting rail away, at least one leg of the mounting rail clamping comprehensive Metal base and one leg connected to the metal base The support rail has electrically contacting support spring, wherein the Metal foot is designed as a flat, narrow metal strip. In addition concerns the invention also a metallic protective conductor terminal element with a at least one mounting recess for receiving a leg a support rail having, run as a flat, narrow metal strip Metal base and one connected to the metal base, one Leg of the support rail electrically contacting support spring for use in an electrical terminal block.

Elektrische Reihenklemmen der in Rede stehenden Art werden z. B. bei Elektroinstallationen, d. h. in Installationssystemen, insbesondere in Schaltanlagen, im großen Umfang verwendet. Bei elektrischen Reihenklemmen der in Rede stehenden Art besteht grundsätzlich das Problem, das metallische Schutzleiteranschlußelement elektrisch gut kontaktierend auf der Tragschiene zu befestigen, gleichzeitig auch eine mechanisch optimale Befestigung des Klemmengehäuses zu erzielen und schließlich auch den damit verbundenen Aufwand zu begrenzen.Electrical terminal blocks of the type in question are z. In electrical installations, d. H. in installation systems, in particular in switchgear, used on a large scale. For electrical terminal blocks of in There is basically the problem of the type in question, the metallic one Protective conductor connection element good electrical contact on the mounting rail to attach, at the same time a mechanically optimal attachment of the Terminal housing to achieve and finally the associated To limit effort.

Bei einer aus der DE 31 26 535 C2 bekannten elektrischen Reihenklemme weist das metallische Schutzleiteranschlußelement neben einem im wesentlichen U-förmigen Metallfuß eine mit dem Metallfuß verbundene, einen Schenkel der Tragschiene elektrisch kontaktierende Auflagefeder auf. Durch die Verwendung einer zusätzlichen Auflagefeder soll die elektrische Kontaktierung des metallischen Schutzleiteranschlußelements mit der Tragschiene verbessert werden. Bei der bekannten elektrischen Reihenklemme ist dabei die Auflagefeder zwischen den beiden parallel verlaufenden Schenkeln des Metallfußes in einer Lageraufnahme festgesetzt bzw. eingehängt. Der bekannte Metallfuß weist somit einen U-förmigen Querschnitt auf. Die Auflagefeder bildet dabei einen Teil des Leiteranschlußraumes für den Schutzleiter und wird über eine Druckschraube gegen den Schenkel der Tragschiene gedrückt. Hierzu ist die Auflagefeder in ihrer Längserstreckung mehrfach abgewinkelt ausgebildet, so daß sich eine dem Schenkel der Tragschiene gegenüberliegende Andruckausformung ergibt. Die elektrische Kontaktwirkung ist davon abhängig, wie stark die Klemmschraube eingedreht wird, so daß sich bei Schutzleitern mit unterschiedlich großem Querschnitt ein unterschiedlich starker Anpreßdruck auf den Schenkel der Tragschiene ergibt.In one known from DE 31 26 535 C2 electrical terminal has the metallic protective conductor terminal adjacent to a substantially U-shaped metal base one connected to the metal base, one Leg of the mounting rail electrically contacting support spring. By the use of an additional support spring is the electrical contact the metallic protective conductor connection element with the mounting rail be improved. In the known electrical terminal is included the support spring between the two parallel legs of the Fixed metal foot in a bearing mount or hung. The known Metal base thus has a U-shaped cross-section. The support spring forms part of the conductor connection space for the protective conductor and is pressed by a pressure screw against the leg of the support rail. For this purpose, the support spring is angled several times in its longitudinal extent formed so that a leg of the support rail opposite Andruckausformung results. The electrical contact effect depends on how strong the clamping screw is screwed in, so that a different with protective conductors with different sized cross section strong contact pressure results on the leg of the mounting rail.

Aus der DE 29 41 932 A 1 ist eine elektrische Reihenklemme bekannt, bei der ein Metallfuß sich vollständig über eine Tragschiene hinweg erstreckt und beide Schenkel der Tragschiene klemmend umfaßt. Der Metallfuß ist dabei als hochkant stehender, doppelter, im wesentlichen U-förmiger Metallstreifen ausgeführt. Die beiden Metallstreifen des Metallfußes weisen an einer Seite, d. h. an einem Schenkel des U-förmigen Metallfußes, eine nutenartige Befestigungsausnehmung für den Schenkel der Tragschiene auf. An dieser Seite des Metallfußes ist auch der Schutzleiteranschlußkörper der elektrischen Reihenklemme angeordnet, wobei die beiden Metallstreifen des Metallfußes die Seitenwandungen des Schutzleiteranschlußkörpers bilden. Die mechanische Befestigung der elektrischen Reihenklemme und die elektrische Kontaktierung des metallischen Schutzleiteranschlußelements mit der Tragschiene erfolgt nun dadurch, daß eine Klemmschraube des als Schraubanschlußkörper ausgeführten Schutzleiteranschlußkörpers angezogen wird. Bei dieser bekannten elektrischen Reihenklemme hängt sowohl die mechanische Befestigung der Reihenklemme als auch der elektrische Kontakt des Schutzleiters mit der Tragschiene davon ab, wie exakt die Klemmschraube des Schutzleiteranschlußkörpers angezogen ist.From DE 29 41 932 A 1, an electrical terminal is known in the a metal foot extends completely over a mounting rail and includes both legs of the mounting rail clamped. The metal base is as upright standing, double, substantially U-shaped metal strip executed. The two metal strips of the metal base point to one side, d. H. on a leg of the U-shaped metal base, a groove-like mounting recess for the leg of the mounting rail. On this page of the metal foot is also the protective earth terminal body of the electric Terminal block arranged, with the two metal strips of the metal base form the side walls of the protective conductor connection body. The mechanical Fixing the electrical terminal block and the electrical contact the metallic protective conductor connection element with the mounting rail Now takes place in that a clamping screw of the screw connection body is carried out executed protective conductor connection body. In this known Electrical terminal hangs both the mechanical attachment the terminal block as well as the electrical contact of the protective conductor with the DIN rail from how exactly the clamping screw of the protective conductor connection body is attracted.

Beiden zuvor beschriebenen Konstruktionen ist gemeinsam, daß die Gestaltung des Metallfußes mit zwei parallel verlaufenden Schenkeln aufwendig und damit relativ teuer ist. Außerdem besteht durch das Festsetzen des metallischen Schutzleiterelements durch Anziehen der Klemmschraube die Gefahr, daß durch den außermittigen Angriffspunkt auf nur einem Schenkel der Tragschiene das metallische Schutzleiteranschlußelement und damit die elektrische Reihenklemme insgesamt von dem anderen Schenkel der Tragschiene abgehoben wird.Both constructions described above have in common that the design the metal base with two parallel legs consuming and thus relatively expensive. In addition, by the setting of the metallic Protective conductor element by tightening the clamping screw the risk that by the off-center point on only one leg of the mounting rail the metallic protective conductor connection element and thus the electrical Terminal block in total from the other leg of the mounting rail is lifted.

Aus der DE 37 32 267 C1,die als nächstliegender Stand der Technik angesehen wird ist eine eingangs beschriebene elektrische Reihenklemme und ein eingangs beschriebenes metallisches Schutzleiteranschlußelement bekannt, bei der ein Metallfuß sich vollständig über eine Tragschiene hinweg erstreckt und beide Schenkel der Tragschiene klemmend umfaßt. Der Metallfuß ist dabei als flacher Metallstreifen ausgeführt, dessen Breitseite der Tragschiene zugewandt ist. Aus dem Metallfuß ist an mindestens einer Seite eine Lasche herausgebogen, die einen Schenkel der Tragschiene unterfaßt oder mit ihrem Ende auf einem Schenkel der Tragschiene aufsitzt, wodurch das Schutzleiteranschlußelement auf der Tragschiene fixiert ist. Problematisch kann hierbei die relativ kleine Fläche der Lasche sein, die den Schenkel der Tragschiene kontaktiert, so daß die Gefahr besteht, daß das Schutzleiteranschlußelement auf der Tragschiene verrutscht.From DE 37 32 267 C1, which is the closest state of the Technology is considered is an electrical terminal described above and a metallic protective conductor connection element described in the introduction known, in which a metal foot completely over a mounting rail extends and includes both legs of the mounting rail by clamping. Of the Metal base is designed as a flat metal strip whose broad side of the Facing rail facing. From the metal base is on at least one side bent out a tab which underlines a leg of the mounting rail or is seated with its end on a leg of the support rail, whereby the protective conductor connection element is fixed on the mounting rail. Problematic Here, the relatively small surface of the tab may be the leg of the Contact rail contacted, so that there is a risk that the protective conductor terminal element slipped on the mounting rail.

Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde, eine elektrische Reihenklemme zum Aufsetzen auf eine Tragschiene zur Verfügung zu stellen, bei der die Herstellung des metallischen Schutzleiteranschlußelements einfach und damit preiswert erfolgen kann, wobei aber dennoch eine gute und zuverlässige elektrische Kontaktierung des metallischen Anschlußelements mit der Tragschiene sichergestellt ist, bzw. ein entsprechendes metallisches Schutzleiteranschlußelement zur Verwendung in einer elektrischen Reihenklemme zur Verfügung zu stellen.The present invention is therefore based on the object, an electrical Terminal block for mounting on a mounting rail available in which the manufacture of the metallic protective conductor connection element simple and therefore inexpensive, but still a good and reliable electrical contacting of the metallic terminal element is ensured with the mounting rail, or a corresponding metallic Protective conductor connection element for use in an electrical Terminal block to provide.

Die zuvor hergeleitete und aufgezeigte Aufgabe ist bei der eingangs beschriebenen elektrischen Reihenklemme zunächst und im wesentlichen dadurch gelöst, daß die Auflagefeder zwei parallele federnde Schenkel aufweist und die Schenkel der Auflagefeder seitlich am Metallfuß anliegen und in Richtung auf einen Schenkel der Tragschiene abgebogen sind. Durch die Vermeidung der "dreidimensionalen" Form des Metallfußes, d. h. der Vermeidung eines Metallfußes mit zwei parallelen Schenkeln, also eines Metallfußes mit einem U-förmigen Querschnitt, ist zum einen die Herstellung des Metallfußes extrem einfach, ergibt sich zum anderen durch die Einsparung des zweiten Schenkels des Metallfußes auch eine entsprechende Materialersparnis. Das sich aus der Realisierung des Metallfußes als nur noch flacher, schmaler Metallstreifen ergebende Problem der Befestigung der Auflagefeder ist erfindungsgemäß dadurch gelöst, daß die Auflagefeder zwei parallele federnde Schenkel aufweist, die seitlich am Metallfuß anliegen und in Richtung auf einen Schenkel der Tragschiene abgebogen sind. Die Verbindung des Metallfußes mit der Auflagefeder wird somit bereits dadurch realisiert daß der Metallfuß zwischen den beiden federnden Schenkeln der Auflagefeder eingeklemmt ist. Die Realisierung der Auflagefeder mit zwei parallelen federnden Schenkeln ist dabei ebenfalls sehr einfach, beispielsweise durch Ausstanzen und Umbiegen der Schenkel möglich.The previously derived and indicated object is described in the introduction electrical terminal initially and essentially thereby solved that the support spring has two parallel resilient legs and the legs of the support spring rest laterally on the metal base and in Direction are bent on a leg of the support rail. By the Avoidance of the "three-dimensional" shape of the metal base, d. H. avoidance a metal base with two parallel legs, so a metal foot with a U-shaped cross-section, is on the one hand the production of the metal foot Extremely simple, on the other hand results from the saving of the second leg of the metal foot also a corresponding saving of material. The result of the realization of the metal foot as only flatter, narrow metal strip resulting problem of attachment of the support spring is inventively achieved in that the support spring two parallel has resilient legs which rest laterally on the metal base and in the direction of a leg of the Rail are bent. The connection the metal base with the support spring is thus already realized that the metal base between the two resilient legs of the support spring is trapped. The realization of the support spring with two parallel resilient legs is also very easy, for example possible by punching and bending the legs.

Vorteilhafterweise erfolgt die Verbindung des Metallfußes mit der Auflagefeder nicht nur durch die Klemmwirkung der beiden parallelen Schenkel der Auflagefeder, sondern zusätzlich durch ein Klemmelement, welches am Metallfuß ausgebildet ist. Das Klemmelement ist dabei vorteilhafterweise einstückig mit dem Metallfuß verbunden und wird dadurch realisiert, daß zwischen dem einen Ende des Klemmelements und dem Rücken des Metallfußes ein Schlitz zum Einstecken der Auflagefeder ausgebildet ist. Durch eine derartige Ausbildung des Klemmelements ist sowohl ein schnelles, aber dennoch genaues Zusammenstecken von Metallfuß und Auflagefeder möglich als auch die Herstellung des Metallfußes in einem einzigen Ausstanzvorgang realisierbar.Advantageously, the connection of the metal base with the support spring not only by the clamping action of the two parallel legs of the Support spring, but additionally by a clamping element, which on the metal base is trained. The clamping element is advantageously one piece connected to the metal base and is realized by that between one end of the clamping element and the back of the metal foot a slot is formed for insertion of the support spring. By such Training the clamping element is both a quick but nonetheless accurate mating of metal base and support spring possible as also the production of the metal foot in a single punching process realizable.

Zur Aufnahme eines Schenkels der Tragschiene weist der Metallfuß mindestens eine Befestigungsausnehmung auf, wobei die Befestigungsausnehmung vorteilhafterweise in etwa U-förmig ausgebildet ist, so daß ein Schenkel bzw. das Endes eines Schenkels der Tragschiene in die Befestigungsausnehmung einsteckbar ist. Die Auflagefeder ist dabei so dimensioniert, daß die Enden der Schenkel der Auflagefeder über die Befestigungsausnehmung hinausragen. Hierdurch ist besonders einfach sichergestellt, daß beim Einstecken des Schenkels der Tragschiene in die Befestigungsausnehmung die Schenkel der Tragschiene mit den Schenkeln der Auflagefeder in Berührung kommen und diese gegen ihre Federkraft wegdrücken, wodurch einerseits ein elektrischer Kontakt zwischen der Auflagefeder und der Tragschiene erfolgt, andererseits der Schenkel der Tragschiene gegen die Befestigungsausnehmung im Metallfuß gedrückt wird, wodurch auch ein guter elektrischer Kontakt zwischen der Tragschiene und dem Metallfuß erfolgt.For receiving a leg of the mounting rail, the metal foot at least a mounting recess, wherein the mounting recess is advantageously formed approximately U-shaped, so that a leg or the end of a leg of the mounting rail in the mounting recess is pluggable. The support spring is dimensioned so that the ends the legs of the support spring protrude beyond the mounting recess. This is particularly easy to ensure that when plugging the leg of the mounting rail in the mounting recess the legs the support rail come into contact with the legs of the support spring and push them away against their spring force, whereby on the one hand an electrical Contact between the support spring and the mounting rail takes place, on the other hand the leg of the mounting rail against the mounting recess in Metal foot is pressed, which also ensures good electrical contact between the support rail and the metal base takes place.

Erstreckt sich der Metallfuß nur teilweise über die Tragschiene und weist der Metallfuß auch nur eine Befestigungsausnehmung auf, so daß der Metallfuß auch nur einen Schenkel der Tragschiene klemmend umfaßt, so ist zwar eine ausreichende elektrische Kontaktierung des metallischen Schutzleiteranschlußelements mit der Tragschiene gewährleistet, zur sicheren mechanischen Befestigung der elektrischen Reihenklemme mit der Tragschiene muß dann jedoch das Klemmengehäuse eine eigene Befestigungsausnehmung aufweisen, in die der zweite Schenkel der Tragschiene eingreift. Vorteilhafterweise ist deshalb der Metallfuß so ausgestaltet, daß er die Tragschiene vollständig übergreift und etwa U-förmig ausgebildet ist und beide Schenkel der Tragschiene klemmend umfaßt. In diesem Fall wird durch das metallische Schutzleiteranschlußelement nicht nur die elektrische Kontaktierung eines Schutzleiters mit der Tragschiene sondern auch die mechanische Befestigung der elektrischen Reihenklemme auf der Tragschiene realisiert.The metal base extends only partially over the mounting rail and has the Metallfuß also only a mounting recess on, so that the metal base includes only one leg of the mounting rail clamped, so while one is sufficient electrical contacting of the metallic protective conductor connection element guaranteed with the mounting rail, for safe mechanical Fixing the electrical terminal with the mounting rail must then However, the terminal housing have its own mounting recess, in which the second leg of the mounting rail engages. advantageously, Therefore, the metal base is designed so that it is the support rail completely engages and is approximately U-shaped and both legs of the mounting rail clamped. In this case, by the metallic protective conductor connection element not just the electrical contacting of a protective conductor with the mounting rail but also the mechanical attachment of the realized electrical terminal on the mounting rail.

Da sich die erfindungsgemäße elektrische Reihenklemme von den bekannten elektrischen Reihenklemmen nur durch die Ausgestaltung des metallischen Schutzleiteranschlußelements unterscheidet, ist Gegenstand der vorliegenden Erfindung nicht nur eine derartige elektrische Reihenklemme, sondern auch das metallische Schutzleiteranschlußelement als solches.Since the electrical terminal according to the invention of the known electrical terminal blocks only by the design of the metallic Protective earth terminal element is different, is the subject of the present Invention not only such an electrical terminal block, but also the metallic protective conductor connection element as such.

Das im Fuße der elektrischen Reihenklemme 1 angeordnete Schutzleiteranschlußelement 6 besteht aus einem Metallfuß 11 und einer Auflagefeder 12. Die Tragschiene 2 wird dabei in dem hier dargestellten Ausführungsbeispiel vollständig von dem Metallfuß 11 übergriffen, wozu dieser etwa U-förmig ausgebildet ist und die beiden Schenkel 3, 4 der Tragschiene 2 klemmend umfaßt.The arranged in the foot of the electrical terminal 1 protective conductor terminal element 6 consists of a metal base 11 and a support spring 12th The support rail 2 is in the embodiment shown here completely overlapped by the metal base 11, what this about U-shaped is formed and the two legs 3, 4 of the support rail 2 comprises clamping.

Erfindungsgemäß ist das metallische Schutzleiteranschlußelement 6 nun dadurch besonders einfach und damit auch kostengünstig herstellbar, daß der Metallfuß 11 als flacher, schmaler Metallstreifen ausgeführt ist und die Auflagefeder 12 zwei parallele federnde Schenkel 13 aufweist, die seitlich an dem Metallfuß 11 anliegen und in Richtung auf den Schenkel 3 der Tragschiene 2 abgebogen sind.According to the invention, the metallic protective conductor connection element 6 is now characterized very simple and therefore inexpensive to produce that the Metal foot 11 is designed as a flat, narrow metal strip and the support spring 12 has two parallel resilient legs 13, the side of the Metal foot 11 abut and in the direction of the leg 3 of the support rail. 2 are bent.

Insbesondere in Fig. 2 erkennt man, daß im Ausführungsbeispiel die Auflagefeder 12 nicht lediglich dadurch mit dem Metallfuß 11 verbunden ist, daß die beiden Schenkel 13 der Auflagefeder 12 seitlich am Metallfuß 11 anliegen, den Metallfuß 11 somit einklemmen, sondern daß zusätzlich am Metallfuß 11 ein Klemmelement 14 ausgebildet ist. Dieses Klemmelement 14 ist nun vorteilhafterweise einstückig mit dem Metallfuß 11 verbunden, wobei zur Befestigung der Auflagefeder 12 zwischen einem Ende 15 des Klemmelements 14 und dem Rücken 16 des Metallfußes 11 ein Schlitz 17 zum Einstecken der Auflagefeder 12 ausgebildet ist. Dadurch, daß der Metallfuß 11 als flacher, schmaler Metallstreifen ausgeführt ist, kann der gesamte Metallfuß 11 zusammen mit dem Klemmelement 14 und dem Schlitz 17 in einem einzigen Ausstanzvorgang hergestellt werden. Ebenso einfach kann die Auflagefeder 12 durch Ausstanzen und anschließendes Umbiegen der Schenkel 13 hergestellt werden.In particular, in Fig. 2 it can be seen that in the embodiment, the support spring 12 is not merely connected to the metal base 11 that the abut both legs 13 of the support spring 12 laterally on the metal foot 11, thus pinch the metal base 11, but that in addition to the metal foot 11th a clamping element 14 is formed. This clamping element 14 is now advantageously integrally connected to the metal base 11, wherein for attachment the support spring 12 between an end 15 of the clamping member 14th and the back 16 of the metal base 11, a slot 17 for insertion of the Support spring 12 is formed. Characterized in that the metal foot 11 as a shallow, narrow metal strip is executed, the entire metal foot 11 can together with the clamping element 14 and the slot 17 in a single punching operation getting produced. Just as easily, the support spring 12th made by punching and then bending the legs 13 become.

Die Auflagefeder 12 weist im Ausführungsbeispiel neben den beiden Schenkeln 13 einen die beiden Schenkel 13 verbindenden Steg 18 auf, wobei der Steg 18 auf dem Rücken 16 des Metallfußes 11 aufliegt und zumindest teilweise in den Schlitz 17 eingeschoben ist, so daß der Steg 18 und damit auch die Auflagefeder 12 durch das Klemmelement 14 und den Rücken 16 des Metallfußes 11 festgesetzt ist. Durch die Länge des Schlitzes 17 bzw. die Länge des Steges 18 kann die genaue Position der Auflagefeder 12 im Bezug zu dem Metallfuß 11 festgelegt werden. Somit wird dann, wenn der Steg 18 bis zum Anschlag in den Schlitz 17 eingeschoben wird, stets eine feste Zuordnung von Metallfuß 11 und Auflagefeder 12 sichergestellt.The support spring 12 has in the embodiment in addition to the two legs 13 a connecting the two legs 13 web 18, wherein the Ridge 18 rests on the back 16 of the metal base 11 and at least partially is inserted into the slot 17 so that the web 18 and thus also the support spring 12 by the clamping element 14 and the back 16 of the Metal foot 11 is fixed. By the length of the slot 17 and the Length of the web 18, the exact position of the support spring 12 in relation be set to the metal foot 11. Thus, when the web 18 is inserted until it stops in the slot 17, always a fixed assignment ensured by metal foot 11 and support spring 12.

Sowohl in Fig. 1 als auch in Fig. 2 ist erkennbar, daß im dargestellten Ausführungsbeispiel einer erfindungsgemäßen Reihenklemme 1 der Metallfuß 11 eine Befestigungsausnehmung 19 zur Aufnahme eines Schenkels 3 der Tragschiene 2 aufweist. Anhand eines Vergleiches der Fig. 1 und 2 soll nun erläutert werden, wie durch die Auflagefeder 12 ein guter und dauerhafter elektrischer Kontakt zwischen der Tragschiene 2 und dem Schutzleiteranschlußelement 6 sichergestellt wird:Both in Fig. 1 and in Fig. 2 it can be seen that in the illustrated embodiment an inventive terminal 1 of the metal base 11th a mounting recess 19 for receiving a leg 3 of the support rail 2 has. Reference to a comparison of Figs. 1 and 2 will now be explained be as by the support spring 12 is a good and durable electrical Contact between the mounting rail 2 and the protective conductor connection element 6 is ensured:

Die Schenkel 13 der Auflagefeder 12 sind derart ausgebildet, daß sie über die Befestigungsausnehmung 19 hinausragen. Über die Befestigungsausnehmung 19 hinausragen bedeutet dabei - wie anhand von Fig. 2 eindeutig erkennbar ist -, daß die Schenkel 13 seitlich an den Befestigungsausnehmungen 19 vorbeilaufen, wenn in diese kein Schenkel 3 einer Tragschiene 2 eingerastet ist. Mit anderen Worten bedeutet dies, daß die Schenkel 13 die Befestigungsausnehmungen 19 zumindest teilweise verschließen. Wird nun ein Schenkel 3 einer Tragschiene 2 in die Befestigungsausnehmung 19 eingesteckt (vgl. Fig. 1), so werden die federnden Schenkel 13 der Auflagefeder 12 gegen ihre Federkraft nach oben weggedrückt, so daß sie die Befestigungsausnehmung 19 freigeben und der Schenkel 3 der Tragschiene 2 eingesteckt werden kann. Dadurch, daß die federnden Schenkel 13 der Auflagefeder 12 gegen ihre Federkraft ausgelenkt werden, drücken sie mit einem ihrer Federkraft entsprechenden Anpreßdruck gegen das Ende des Schenkels 3 der Tragschiene 2. Dadurch findet zum einen ein elektrischer Kontakt zwischen dem Schenkel 3 der Tragschiene 2 und den Schenkeln 13 der Auflagefeder 12 statt, wird jedoch zum anderen auch der Schenkel 3 der Tragschiene 2 nach unten und somit gegen den unteren Rand der Befestigungsausnehmung 19 gedrückt. Dadurch erfolgt dann auch eine elektrische Kontaktierung des Schenkels 3 der Tragschiene 2 mit dem Metallfuß 11. Durch die beiden parallelen federnden Schenkel 13 der Auflagefeder 12, welche unabhängig voneinander ausgelenkt werden, erfolgt nicht nur eine gute elektrische Kontaktierung der Tragschiene 2, sondern gleichzeitig auch eine Ausrichtung des schmalen Metallfußes 11 auf der Tragschiene 2.The legs 13 of the support spring 12 are formed such that they over the Mounting recess 19 protrude. About the mounting recess 19 protrude means - as clearly apparent from Fig. 2 is - that the legs 13 laterally to the mounting recesses 19 pass, if no leg 3 of a mounting rail 2 locked in this is. In other words, this means that the legs 13, the mounting recesses 19 at least partially close. Will now be Leg 3 of a support rail 2 inserted into the mounting recess 19 (see Fig. 1), the resilient legs 13 of the support spring 12th pushed upwards against its spring force, so that they the Befestigungsausnehmung 19 release and the leg 3 of the support rail 2 inserted can be. Characterized in that the resilient leg 13 of the support spring 12th are deflected against their spring force, they press with one of their spring force corresponding contact pressure against the end of the leg 3 of the Support rail 2. As a result, on the one hand, an electrical contact between the leg 3 of the support rail 2 and the legs 13 of the support spring 12 instead, but on the other hand, the leg 3 of the support rail. 2 down and thus against the lower edge of the mounting recess 19 pressed. This then also takes an electrical contact of the leg 3 of the support rail 2 with the metal foot 11. Through the two parallel resilient leg 13 of the support spring 12, which independently are deflected from each other, not only a good electrical Contacting the support rail 2, but at the same time an orientation of the narrow metal foot 11 on the mounting rail. 2

Bei dem in den Fig. 1 und 2 dargestellten metallischen Schutzleiteranschlußelement 6 ist der Metallfuß 11 etwa U-förmig ausgebildet, wobei der Metallfuß 11 beide Schenkel 3, 4 der Tragschiene 2 übergreift. Daneben ist jedoch auch eine Ausbildung des Metallfußes 11 und damit auch des Schutzleiteranschlußelements 6 möglich, bei dem der Metallfuß 11 die Tragschiene 2 nur teilweise, beispielsweise nur halb übergreift. Dann muß zur mechanischen Befestigung der elektrischen Reihenklemme 1 auf der Tragschiene 2 eine zweite Befestigungsausnehmung in dem Klemmengehäuse 5 der elektrischen Reihenklemme 1 realisiert sein.In the illustrated in Figs. 1 and 2 metallic protective conductor terminal element 6, the metal base 11 is approximately U-shaped, wherein the metal base 11 both legs 3, 4 of the support rail 2 overlaps. Besides that, however, is also an embodiment of the metal base 11 and thus also of the protective conductor connection element 6 possible, in which the metal base 11, the support rail 2 only partially, for example, only half overlaps. Then must for mechanical fastening the electrical terminal 1 on the mounting rail 2, a second Mounting recess in the terminal housing 5 of the electrical terminal 1 be realized.

Neben den in Fig. 1 ausschließlich dargestellten Schraubklemmen sind zur Realisierung des Anschlusses von elektrischen Leitungen an die Reihenklemme 1 auch andere, beliebige Anschlußtechniken, insbesondere Zugfederklemmen, verwendbar.In addition to the screw terminals exclusively shown in Fig. 1 are for Realization of the connection of electrical wires to the terminal block 1 also other, any connection techniques, in particular tension spring terminals, usable.
