Description

Die Erfindung betrifft eine elektrische Reihenklemme zum Aufsetzen auf eine Tragschiene mit vorzugsweise zwei Schenkeln, mit einem aus Isolierstoff bestehenden Klemmengehäuse und mit einem im Fuß des Klemmengehäuses angeordneten metallischen Schutzleiteranschlußelement, wobei das Klemmgehäuse mindestens eine Schutzleiteranschlußklemme und vorzugsweise zwei Außenleiterdurchgangsklemmen aufweist und wobei das Schutzleiteranschlußelement einen sich zumindest teilweise über die Tragschiene hinweg erstreckenden, mindestens einen Schenkel der Tragschiene klemmend umfassenden Metallfuß und eine mit dem Metallfuß verbundene, einen Schenkel der Tragschiene elektrisch kontaktierende Auflagefeder aufweist. Daneben betrifft die Erfindung auch ein metallisches Schutzleiteranschlußelement mit einem mindestens eine Befestigungsausnehmung zur Aufnahme eines Schenkels einer Tragschiene aufweisenden 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 block for mounting on a Carrier rail with preferably two legs, with one made of insulating material Terminal housing and with one arranged in the base of the terminal housing metallic protective conductor connection element, the terminal housing at least one protective conductor terminal and preferably two Has outer conductor feed-through terminals and wherein the protective conductor connection element one at least partially over the mounting rail extending, encompassing at least one leg of the mounting rail Metal foot and a leg connected to the metal foot the mounting rail has electrically contacting support spring. Besides The invention also relates to a metallic protective conductor connection element an at least one mounting recess for receiving a Leg of a mounting rail having a metal base and with one with the Metal foot connected, electrically contacting one leg of the mounting rail 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, for. B. in electrical installations, d. H. in installation systems, especially in switchgear, used on a large scale. With electrical terminal blocks the in Basically speaking, there is the problem, the metallic one Protective conductor connection element making good electrical contact on the mounting rail to attach, at the same time a mechanically optimal attachment of the To achieve terminal housing and finally the associated Limit effort.

Bei der bekannten elektrischen Reihenklemme, von der die Erfindung ausgeht (deutsche Patentschrift 31 26 535), 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 the known electrical terminal block from which the invention is based (German Patent 31 26 535), has the metallic protective conductor connection element in addition to a substantially U-shaped metal base with connected to the metal foot, electrically contacting one leg of the mounting rail Support spring on. By using an additional The contact spring should be the electrical contacting of the metallic protective conductor connection element can be improved with the mounting rail. With the known electrical terminal block is the contact spring between the two parallel legs of the metal base in a bearing seat fixed or suspended. The known metal base thus has a U-shaped Cross section on. The support spring forms part of the conductor connection space for the protective conductor and is countered by a pressure screw pressed the leg of the mounting rail. The support spring is in their longitudinal extension formed multiple angled so that there is a pressure formation opposite the leg of the mounting rail results. The electrical contact effect depends on how strong the Clamping screw is screwed in so that there are different protective conductors large cross section a differently strong contact pressure the leg of the mounting rail results.

Aus der deutschen Offenlegungsschrift 29 41 932 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 the German patent application 29 41 932 is an electrical terminal block known, in which a metal foot is completely on a mounting rail extends away and embraces both legs of the mounting rail. The Metal foot is an upright, double, essentially U-shaped Running metal strips. The two metal strips of the metal base point to one side, d. H. on one leg of the U-shaped metal base, a groove-like mounting recess for the leg of the mounting rail on. The protective conductor connection body is also on this side of the metal base the electrical terminal block arranged, the two metal strips of the metal base form the side walls of the protective conductor connection body. The mechanical fastening of the electrical terminal block and the electrical contacting of the metallic protective conductor connection element with the mounting rail is now done in that a clamping screw as Screw connection body designed protective conductor connection body tightened becomes. In this known electrical terminal block depends both mechanical fastening of the terminal block as well as the electrical contact of the protective conductor with the mounting rail depends on how precise the clamping screw of the protective conductor connection body is tightened.

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 previously described constructions have in common that the design of the metal base with two parallel legs and is therefore relatively expensive. There is also by fixing the metallic Protective conductor element by tightening the clamping screw that by the off-center point of attack 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 off.

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 of an electrical Terminal block available for mounting on a mounting rail ask in the manufacture of the metallic protective conductor connection element simple and therefore inexpensive, but still a good one and reliable electrical contacting of the metallic connecting element is ensured with the mounting rail, or a corresponding metallic Protective conductor connection element for use in an electrical To provide terminal blocks.

Die zuvor hergeleitete und aufgezeigte Aufgabe ist bei der eingangs beschriebenen elektrischen Reihenklemme zunächst und im wesentlichen dadurch gelöst, daß der Metallfuß als flacher, schmaler Metallstreifen ausgeführt ist, 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. 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 shown task is the one described at the beginning electrical terminal block initially and essentially thereby solved that the metal base is designed as a flat, narrow metal strip is, the support spring has two parallel resilient legs and the Leg of the support spring lie on the side of the metal foot and in the direction are bent on one leg of the mounting rail. By avoiding it the "three-dimensional" shape of the metal base, d. H. avoiding one Metal base with two parallel legs, i.e. a metal base with one U-shaped cross-section, on the one hand, the manufacture of the metal base is extreme simply results from the saving of the second leg of the metal base also a corresponding material saving. That out the realization of the metal base as a flat, narrow metal strip resulting problem of fastening the support spring is according to the invention solved in that the support spring has two parallel resilient legs, which are on the side of the metal base. The connection of the metal foot with the support spring is thus already realized in that the metal foot between the two resilient legs of the support spring is clamped. The support spring is realized with two parallel resilient legs is also very easy, for example by punching and bending the thigh possible.

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.The metal base is advantageously connected to the support spring not only by the clamping action of the two parallel legs Support spring, but also by a clamping element, which is on the metal base is trained. The clamping element is advantageously in one piece connected to the metal base and is realized in that between one end of the clamping element and the back of the metal foot a slot for inserting the support spring is formed. By such Training of the clamping element is both quick, but still exact assembly of metal foot and support spring possible as also the production of the metal base 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.The metal base has at least one point for receiving a leg of the mounting rail a mounting recess, the mounting recess is advantageously approximately U-shaped, so that one leg or the end of a leg of the mounting rail in the mounting recess is insertable. The support spring is dimensioned so that the ends the leg of the support spring protrudes beyond the mounting recess. This ensures in a particularly simple manner that when plugging in of the leg of the mounting rail in the mounting recess, the legs the mounting rail come into contact with the legs of the support spring and push them away against their spring force, creating an electrical one On the other hand, there is contact between the support spring and the mounting rail the leg of the mounting rail against the mounting recess in Metal foot is pressed, which also ensures good electrical contact between the mounting rail and the metal base.

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 foot only partially extends over the mounting rail and points the Metal base also only a mounting recess, so that the metal base includes only one leg of the mounting rail by clamping, there is indeed one adequate electrical contacting of the metallic protective conductor connection element guaranteed with the mounting rail, for safe mechanical The electrical terminal block must then be fastened to the mounting rail however, the terminal housing has its own fastening recess, into which the second leg of the mounting rail engages. advantageously, is therefore the metal base designed so that it completely the mounting rail engages and is approximately U-shaped and both legs of the mounting rail clamped embraced. In this case, the metal protective conductor connection element not just the electrical contacting of a protective conductor with the mounting rail but also the mechanical attachment of the electrical terminal block realized 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 block according to the invention differs from the known electrical terminal blocks only by the design of the metallic Protective conductor connecting element is the subject of the present Invention not only such an electrical terminal block, but also the metallic protective conductor connection element as such.

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 thereby particularly simple and thus also inexpensive to produce that the Metal base 11 is designed as a flat, narrow metal strip and the support spring 12 has two parallel resilient legs 13, the side of the Fit metal base 11 and in the direction of leg 3 of mounting rail 2 are turned.

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 the support spring in the embodiment 12 is not only connected to the metal base 11 in that the both legs 13 of the support spring 12 lie laterally on the metal base 11, thus clamp the metal foot 11, but that additionally on the metal foot 11 a clamping element 14 is formed. This clamping element 14 is now advantageously integrally connected to the metal base 11, being for attachment the support spring 12 between one end 15 of the clamping element 14 and the back 16 of the metal base 11, a slot 17 for inserting the Support spring 12 is formed. The fact that the metal base 11 as a flat, Narrow metal strip is executed, the entire metal base 11 can be together with the clamping element 14 and the slot 17 in a single punching process getting produced. The support spring 12 can be just as simple produced by punching out 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 exemplary embodiment next to the two legs 13 on a web 18 connecting the two legs 13, the Web 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 base 11 is fixed. By the length of the slot 17 and the Length of the web 18 can refer to the exact position of the support spring 12 to be fixed to the metal base 11. Thus, when the web 18 is inserted into the slot 17 until it stops, always a fixed assignment ensured by metal base 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 a terminal block 1 according to the invention, the metal foot 11 a mounting recess 19 for receiving a leg 3 of the mounting rail 2 has. Based on a comparison of FIGS. 1 and 2 will now be explained become, as by the support spring 12 a good and permanent electrical Contact between the mounting rail 2 and the protective conductor connection element 6 ensures:

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 designed such that they over the Project mounting recess 19. About the mounting recess 19 protrudes - as can be clearly seen from FIG. 2 is - that the legs 13 laterally on the mounting recesses 19 run past if no leg 3 of a mounting rail 2 is snapped into this is. In other words, this means that the legs 13 have the fastening recesses 19 at least partially seal. Now becomes a Leg 3 of a mounting rail 2 is inserted into the mounting recess 19 (cf. FIG. 1), the resilient legs 13 of the support spring 12 pushed upward against its spring force so that it has the mounting recess 19 release and the leg 3 of the mounting rail 2 inserted can be. The fact that the resilient legs 13 of the support spring 12th are deflected against their spring force, press with one of their spring force corresponding contact pressure against the end of the leg 3 of the Carrier rail 2. This creates an electrical contact between the leg 3 of the mounting rail 2 and the legs 13 of the support spring 12 instead of, but on the other hand also the leg 3 of the mounting rail 2 down and thus against the lower edge of the mounting recess 19 pressed. This then also makes electrical contact of the leg 3 of the mounting rail 2 with the metal base 11. Through the two parallel resilient leg 13 of the support spring 12, which is independent are deflected from each other, not only does a good electrical Contacting the mounting rail 2, but also an alignment 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 metallic protective conductor connection element shown in FIGS. 1 and 2 6, the metal base 11 is approximately U-shaped, the metal base 11 overlaps both legs 3, 4 of the mounting rail 2. However, is next also a design of the metal base 11 and thus also the protective conductor connection element 6 possible, in which the metal base 11, the mounting rail 2 only partially, for example only half overlaps. Then for mechanical fastening the electrical terminal block 1 on the mounting rail 2 a second Fastening recess in the terminal housing 5 of the electrical terminal block 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 shown exclusively in Fig. 1 are for Realization of the connection of electrical lines to the terminal block 1 also any other connection technology, in particular tension spring terminals, usable.
