Nachteilig an derartigen Anschlussgehäusen, insbesondere Reihenklemmengehäusen, ist oftmals der relativ aufwendige Aufbau. Dieser soll daher nach der Erfindung möglichst einfach gestaltet werden.

Die Lösung dieses Problems ist die Aufgabe der Erfindung. The solution to this problem is the object of the invention.
Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruchs 1 . Geschaffen werden ferner eine Reihenklemme oder ein Stecker mit einem Anschlussgehäu- se und wenigstens einer Anschlussvorrichtung oder mehreren Anschlussvorrichtungen nach einem der darauf bezogenen Ansprüche. Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen. The invention solves this problem by the subject matter of claim 1.

Es wird deutlich, dass der im Anspruch 1 und auch der in einem oder mehreren der weiteren Unteransprüche für das Anschlussgehäuse vorgeschlagene Leiteranschluss besonders gut dazu geeignet ist, vormontiert in ein Anschlussgehäuse, insbesondere ein Reihenklemmengehäuse, eingesetzt zu werden, um dort als der einzige oder einer von mehreren Leiteranschlüssen des Gehäuses verwendet zu werden. Dabei ist der einzuführende Leiter ausgesprochen gut von Leiterführungen an vorzugsweise mehreren, insbesondere allen, Seiten umgeben. Damit wird das Anschließen auch feindrähtiger Leiter sehr einfach. Dazu ist die Reihenklemme einfach aufgebaut und ebenso einfach und gut montierbar. Besonders bevorzugt weist der wenigstens eine (oder die mehreren) Federträger daher nur an einer seiner Seiten der Grundwand eine Funktionskontur auf, um die Klemmfeder zu halten. Dies ist die Seite, die zur Rückwand des Anschlussgehäuses hin orientiert ist bzw-. liegt.

Fig. 2a zeigt eine erste Ausführungsvariante einer Anschlussvorrichtung 1 für Leiter. Diese Anschlussvorrichtung 1 ist als Einfach -Leiteranschluss 2 ausgebildet, der an einer Stromschiene 8 angebracht ist und (rein beispielhaft) den Anschluss bzw. ein elektrisches Kontaktieren eines Leiterendes erlaubt (hier nicht dargestellt). Die Anschlussvorrichtung 1 der Fig. 2b weist hingegen drei Einzel-Leiteranschlüsse 2; 3, 4 auf, die an einer Stromschiene 8 angebracht sind, so dass insgesamt drei Leiter anschließbar sind. Fig. 2a shows a first embodiment of a connection device 1 for conductors. This connection device 1 is designed as a single-conductor connection 2, which is attached to a busbar 8 and (purely by way of example) the connection or a electrically contacting a conductor end allowed (not shown here). By contrast, the connection device 1 of FIG. 2b has three individual conductor connections 2; 3, 4, which are attached to a busbar 8, so that a total of three conductors can be connected.
Die Einzel-Leiteranschlüsse 2, 3, 4 sind jeweils als Direktsteckanschlüsse (Push-in genannt) ausgebildet. Jeder der (eins, zwei oder mehr; hier beispielhaft drei) Einzel- Leiteranschlüsse 2, 3, 4 (siehe auch Fig. 1 a) weist jeweils ein metallisches Kontaktelement 5 oder einen Klemmkäfig, einen Federträger 6 aus nicht leitendem Material, insbesondere einem nicht leitenden Kunststoff sowie eine Klemmfeder 7 auf. Derart wird jeweils ein in sich abgeschlossen funktionsfähiger Einzel-Leiteranschluss 2 gebildet, der aber vorzugsweise mit weiteren Einzel-Leiteranschlüssen 3, 4 insbesondere zu in Reihe angeordneten Mehrfach-Leiteranschlüssen zusammensetzbar ist. Jedes Kontaktelement 5 weist hier eine L-Form mit einem Grundschenkel 5a und einem Kontaktschenkel 5b auf. Der Grundschenkel 5a dient zur Befestigung des jeweiligen Kontaktelements 5 auf der Stromschiene 8. Dazu wird der Grundschenkel 5a an die Stromschiene 8 vorzugsweise angelötet oder angeschweißt. Die zwei oder mehr Kontaktelemente 5 sind in einer Längserstreckungsrichtung Y der Stromschie- ne 8 hintereinander angeordnet. Da die Kontaktelemente 5 nicht einstückig mit der Stromschiene 8 ausgebildet sind sondern an dieser befestigt sind, können sie in Längserstreckungsrichtung Y der Stromschiene 8 dicht hintereinander angeordnet werden. Insbesondere kann ihr Abstand in Y-Richtung sehr viel kleiner sein als die Längserstreckung der Federträger 6. Es ist aber auch denkbar, die Kontaktschenkel 5b aus dem Material der Stromschiene 8 freizustanzen und auszubiegen (hier nicht dargestellt) oder aber als Kontaktelemente 5 Klemmkäfige mit einer anderen Geometrie als einer L-Form vorzusehen. The individual conductor connections 2, 3, 4 are each designed as direct plug connections (called push-in). Each of the (one, two or more, three exemplified here) single conductor terminals 2, 3, 4 (see also Fig. 1 a) each has a metallic contact element 5 or a clamping cage, a spring support 6 of non-conductive material, especially one not conductive plastic and a clamping spring 7. In this way, a self-contained single-wire connection 2 is formed in each case, which, however, can preferably be combined with further individual conductor connections 3, 4, in particular to multiple-conductor connections arranged in series. Each contact element 5 here has an L-shape with a base leg 5a and a contact leg 5b. The base leg 5a serves for fastening the respective contact element 5 on the busbar 8. For this purpose, the base leg 5a is preferably soldered or welded to the busbar 8. The two or more contact elements 5 are arranged one behind the other in a longitudinal extension direction Y of the busbar 8. Since the contact elements 5 are not formed integrally with the busbar 8 but are attached to this, they can be arranged in the longitudinal extension direction Y of the busbar 8 close to each other. In particular, their distance in the Y direction can be much smaller than the longitudinal extent of the spring carrier 6. However, it is also conceivable to free-punch and bend out the contact legs 5b from the material of the busbar 8 (not shown here) or as contact elements 5 clamping cages with a geometry other than an L-shape.
Die Federträger 6 weisen in Draufsicht (siehe auch Fig. 2) eine U-Form mit einer Grundwand 6a und zwei sich hierzu senkrecht erstreckenden Seitenwänden 6b, 6c auf. Senkrecht zur Grundwand 6a erstreckt sich ferner wenigstens eine Federhaltekontur 6d. Der Federträger 6 und/oder das Kontaktelement 5 weisen ferner eines oder mehrere Montagemittel - insbesondere Formschlussmittel und/oder Rastmittel - auf, die zum Zusammenwirken mit korrespondierenden Montagemitteln - insbesondere ebenfalls Formschluss- und/oder Rastmitteln - an einem Aufnahmeelement wie einem An- schlussgehäuse 9, insbesondere einem Reihenklemmen- oder Steckergehäuse - ausgebildet sind. Das Gehäuse 9 ist in X-Richtung - Anreihrichtung genannt - anreihbar gestaltet. The spring carrier 6 have in plan view (see also Fig. 2) a U-shape with a base wall 6a and two perpendicular thereto extending side walls 6b, 6c. Perpendicular to the base wall 6a further extends at least one spring retaining contour 6d. The spring carrier 6 and / or the contact element 5 also have one or more mounting means - in particular positive locking means and / or locking means - on the interaction with corresponding mounting means - in particular also positive locking and / or locking means - on a receiving element such as a connection housing. 9 , in particular a terminal block or plug housing - are formed. The housing 9 is arranged in the X direction - the arrangement direction - arranged in rows.
Das Anschlussgehäuse 9 weist einen Freiraum 10 oder mehrere Freiräume 10 zum Einsetzen des einzigen Federträgers 6 oder mehrerer der Federträger 6 auf und kann auf verschiedene Weise gestaltet sein. Dies wird weiter unten noch näher erläutert. The connection housing 9 has a free space 10 or more free spaces 10 for insertion of the single spring carrier 6 or more of the spring carrier 6 and can be designed in various ways. This will be explained in more detail below.
Die Klemmfeder 7 (siehe auch Fig. 2a) ist im Wesentlichen V-förmig ausgebildet und weist einen Stützschenkel 7a und einen spitzwinklig hierzu in einem Winkel 10° < α < 90° angeordneten Klemmschenkel 7b auf. Der Stützschenkel 7a und der Klemmschenkel 7b sind über einen Federrücken 7c miteinander verbunden. The clamping spring 7 (see also Fig. 2a) is substantially V-shaped and has a support leg 7a and an acute angle thereto at an angle 10 ° <α <90 ° arranged clamping leg 7b. The support leg 7a and the clamping leg 7b are connected to each other via a spring back 7c.
Die Federträger 6 sind derart ausgebildet, dass auf sie die Klemmfedern 7 aufsetzbar sind. Dazu übergreift der Federrücken 7c die Federhaltekontur 6d des Federträgers 6. Der Stützschenkel 7a der Klemmfeder liegt jeweils vorzugweise zwischen der der Federhaltekontur 6d und der einen der beiden Seitenwände 6c. Die Federhaltekontur 6d ist vorzugsweise schräg in einem Federwinkel von vorzugsweise 0 < ß < 60° zur Leitereinführrichtung (im Koordinatensystem -Z) ausgerichtet. Die Federhaltekontur 6d ist ferner vorzugsweise so lang, dass sie sich über die gesamte Länge des Stützschenkels 7a der Klemmfeder 7 erstreckt. Derart ist die Klemmfeder 7 gut vormontierbar. Die Federhaltekontur 6d kann jeweils auch einen Anschlag für eine Öffnungsbewegung des Klemmschenkels 7b der Klemmfeder 7 bilden oder aufweisen. Die Federhaltekontur 6d kann auch aus mehreren einzelnen Abschnitten bestehen. Der Klemmschenkel 7b liegt vorzugsweise im nicht einen Leiter kontaktierenden Zustand an dem Kontaktschenkel 5b an. Er drückt im kontaktierenden Zustand einen Leiter gegen den elektrisch leitenden Kontaktschenkel 5b. Vorzugsweise sind die einen Montagemittel als Rastmittel als einer oder mehrere Vorsprünge 1 1 an dem freien Ende von einem der Kontaktelemente 5 oder an den freien Enden der Kontaktschenkel 5b mehrerer der Kontaktelemente 5 ausgebildet. Im Anschlussgehäuse 9 wird dann / werden dann eines oder mehrere entsprechende Rastgegenmittel, beispielsweise eine oder mehrere Rastkanten ausgebildet, an denen der oder die Vorsprünge 1 1 an dem oder den Kontaktelementen 5 verrastbar sind. The spring carrier 6 are formed such that the clamping springs 7 are placed on them. For this purpose, the spring back 7c engages over the spring holding contour 6d of the spring carrier 6. The supporting leg 7a of the clamping spring is in each case preferably located between that of the spring holding contour 6d and one of the two side walls 6c. The spring holding contour 6d is preferably aligned obliquely in a spring angle of preferably 0 <β <60 ° to the conductor insertion direction (in the coordinate system -Z). The spring retaining contour 6d is also preferably long enough to extend over the entire length of the supporting leg 7a of the clamping spring 7. In this way, the clamping spring 7 is well preassembled. The spring holding contour 6d can each also form or have a stop for an opening movement of the clamping leg 7b of the clamping spring 7. The spring retaining contour 6d can also consist of several individual sections. The clamping leg 7b is preferably in the not contacting a conductor state on the contact leg 5b. He presses in the contacting state, a conductor against the electrically conductive contact leg 5b. Preferably, the one mounting means are formed as latching means as one or more projections 1 1 at the free end of one of the contact elements 5 or at the free ends of the contact legs 5 b of several of the contact elements 5. In the connection housing 9 then one or more corresponding non-locking means, for example, one or more locking edges is then formed at which the one or more projections 1 1 on the one or more contact elements 5 can be latched.
Es ist auch ergänzend oder alternativ denkbar, dass Formschlussmittel wie Zapfen am Anschlussgehäuse 9 und korrespondierende Formschlussmittel als Löcher am Federträger 9 ausgebildet sind (hier nicht dargestellt), welche die Einzel- Leiteranschlüsse am Anschlussgehäuse 9 alleine oder ergänzend sichern. It is also additionally or alternatively conceivable that positive locking means such as pins on the connection housing 9 and corresponding positive locking means are formed as holes on the spring carrier 9 (not shown here), which secure the individual conductor terminals on the connection housing 9 alone or in addition.
Auf jeden der Federträger 6 ist vorzugsweise eine einzige der Klemmfedern 7 auf- setzbar und vormontierbar. Es ist aber auch ein über mehrere Leiter- Einzelanschlüsse durchgängiger Federträger 6 realisierbar (hier nicht dargestellt), an dem dann in einer Reihe (hier in Y— Richtung) hintereinander mehrere der Klemmfedern 7 angeordnet sind. In Fig. 2a wären dann die (hier beispielhaft) drei Federträger 6 einstückig verbunden. Da die Klemmfedern 7 in einer Reihe hintereinander ange- ordnet sind und da die Leiteranschlüsse insofern in Y-Richtung versetzt sind, wird im Rahmen dieser Anmeldung trotzdem eine Reihung von drei Einzel-Leiteranschlüssen unter dieser Ausgestaltung verstanden, welche an separaten Klemmstellen den An- schluss jeweils eines und insgesamt mehrerer Leiter erlaubt. Der oder die Federträger 6 mit der oder den Klemmfedern 7 können von oben auf die Stromschiene 8 mit dem darauf befestigten oder einstückig ausgebildeten Kontaktelement 5 aufgesetzt werden. Dabei greift der Kontaktschenkel 5 zwischen den Klemmschenkel 7b der jeweiligen Klemmfeder 7 und die eine Seitenwand 6b des Federträgers 6 und der Stützschenkel 7a stützt sich an der anderen Seitenwand 6c des Federträgers 6 ab. Der Stützschenkel 7a der Klemmfeder 7 wird damit bevorzugt an einem Element aus Kunststoff abgestützt und nimmt einen Teil der Kontaktkräfte auf. Es ist aber auch denkbar, ihn an einem metallischen Element abzustützen, beispielsweise einem Stromschienenschenkel oder einem Klemmkäfigschenkel eines als Klemmkäfig ausgebildeten Kontaktelementes. Die AbStützung an dem Federträger 7 aus Kunststoff ist besonders kostengünstig und einfach. On each of the spring carrier 6 is preferably a single of the clamping springs 7 can be placed and preassembled. However, it is also possible to implement a spring carrier 6 that is continuous over a plurality of individual conductor connections (not shown here), on which several of the clamping springs 7 are then arranged one after the other in a row (here in the Y direction). In Fig. 2a then the (here exemplified) three spring carrier 6 would be integrally connected. Since the clamping springs 7 are arranged in a row behind one another and since the conductor connections are offset in the Y direction, in the context of this application, a row of three individual conductor connections is nevertheless understood to mean this connection, which connects at separate clamping points one and a total of several conductors allowed. The one or more spring carrier 6 with the or the clamping springs 7 can be placed from above on the busbar 8 with the contact element 5 mounted thereon or integrally formed. In this case, the contact leg 5 engages between the clamping leg 7b of the respective clamping spring 7 and the one side wall 6b of the spring carrier 6 and the support leg 7a is supported on the other side wall 6c of the spring carrier 6. The support leg 7a of the clamping spring 7 is thus preferably supported on a plastic element and absorbs part of the contact forces. But it is also conceivable to support it on a metallic element, such as a busbar leg or a clamping cage legs of a designed as a clamping cage contact element. The support on the spring carrier 7 made of plastic is particularly inexpensive and easy.
Der oder die an der Stromschiene 8 vormontierten Einzel-Leiteranschlüsse 2, 3, 4 werden in das Anschlussgehäuse 9 (hier einer Reihenklemme) mit dem wenigstens einen Freiraum 10 oder den mehreren Freiräumen 10 eingesetzt. Dieser Freiraum 10 bzw. die Freiräume 10 im Reihenklemmengehäuse ist/sind derart bemessen, dass die Stromschiene 8 einsetzbar ist, auf welcher einer oder vorzugsweise in einer Reihe hintereinander mehrere einzelne der Leiteranschlüsse 2, 3, 4 angeordnet sind, die jeweils vorzugsweise einen der Federträger 6, einen der Klemmkäfige 5 und eine der Klemmfedern 7 aufweisen. Im Anschlussgehäuse 9, insbesondere im Reihenklemmengehäuse 9, können ferner eine oder mehrere Leitereinführöffnungen 12 und eine oder mehrere Öffnungen 13 für Drücker oder Schraubendreher oder dgl. vorgesehen sein, die zum Öffnen der Klemmstelle zwischen dem jeweiligen Klemmschenkel 7b und dem jeweiligen Kontaktschenkel 5b dienen. The one or more pre-mounted on the busbar 8 single-wire terminals 2, 3, 4 are in the terminal housing 9 (here a terminal) with the at least one free space 10 or the plurality of free spaces 10 used. This free space 10 or the free spaces 10 in the terminal block housing is / are dimensioned such that the busbar 8 can be used, on which one or preferably in a row several individual of the conductor terminals 2, 3, 4 are arranged, each preferably one of the spring carrier 6, one of the clamping cages 5 and one of the clamping springs 7 have. Furthermore, one or more conductor insertion openings 12 and one or more openings 13 for pushers or screwdrivers or the like may be provided in the connection housing 9, in particular in the terminal block housing 9, which serve to open the nip between the respective clamping leg 7b and the respective contact leg 5b.
Bei der Montage werden zunächst die eine oder mehreren Klemmfedern 7 auf den oder die Federträger 6 aufgesetzt (Fig. 1 a und b). Dann werden der oder die Federträger 6 mit der oder den Klemmfedern 7 auf die Stromschiene 8 aufgesetzt (Fig. 1 c), auf der zuvor die Kontaktelemente 5 befestigt oder ausgebildet worden sind. During assembly, the one or more clamping springs 7 are first placed on the spring carrier or springs 6 (FIGS. 1 a and b). Then, the one or more spring carrier 6 are placed with the or the clamping springs 7 on the busbar 8 (Fig. 1 c), on the previously the contact elements 5 have been attached or formed.
Derart sind die Stromschienen 8 mit den Leiteranschlüssen einfach vormontiert (Fig. 1 c) und können als vormontierte Einheit in das Reihenklemmengehäuse 9 eingesetzt werden, wo das oder die Montagemittel an diesem Anschlussgehäuse und an dem oder den Federträgern 6 oder Kontaktelementen 5 zusammenwirken (Fig. 1 d). In this way, the busbars 8 with the conductor connections are simply preassembled (FIG. 1 c) and can be used as a preassembled unit in the terminal block housing 9, where the mounting means or devices cooperate with this connection housing and with the spring carrier or contact elements 5 (FIG. 1 d).
Das Einsetzen der Einzel-Leiteranschlüsse 2 erfolgt derart, dass eine Anschlussgehäuserückwand 14 und die Federträgergrundwand 6a im Bereich der Freiräume 10 parallel zueinander liegen, wobei die Kontaktelemente 5 und die Kontaktfedern 7 zwischen diesen beiden Wänden 14, 6a liegen. Senkrecht zur Anschlussgehäuserückwand 14 weist das Anschlussgehäuse 9 Wandabschnitte 16 auf, die die Freiräume voneinander trennen und seitlich begrenzen. Derart bilden das Anschlussgehäuse 9 und der Federträger 6 in diesem Bereich jeweils eine in Draufsicht rechteckig geschlossene Geometrie aus. Die Klemmfeder 7 und ein anzuschließender Leiter liegen derart gut geschützt. Insbesondere sind derart auch feindrähtige Leiter leicht anschließbar, denn die Anschlussgehäuserückwand 14, der Kontaktschenkel 5b des Kontaktelementes 5, der Klemmschenkel 7b und auch die Grundwand 6a des Federträgers 6 bilden jeweils Leiterführungen aus, die das Einführen des jeweiligen Leiters in die Klemmstelle vereinfachen. Die Grundwand 6a fluchtet dabei ganz oder wenigstens nahezu mit der Vorderwand 15 des Anschlussgehäuses. Derart kann eine ganz oder nahezu ganz vollständig geschlossene Wand, bestehend aus der Vorderwand 15 und der einen oder den mehreren Grundwänden gebildet werden. Hier ist lediglich der Spalt, in welchem die Stromschiene 8 sitzt, nicht im Bereich der Vorderwand 15 bzw. der Grundwände 6a geschlossen ausgebildet. Die Grundwand 6a bildet vorteilhaft eine Leiterführung zur Seite der Vorderwand 15 hin aus. The insertion of the individual conductor terminals 2 takes place in such a way that a connection housing rear wall 14 and the spring support base wall 6a are parallel to one another in the region of the free spaces 10, the contact elements 5 and the contact springs 7 lying between these two walls 14, 6a. Perpendicular to the connection housing rear wall 14, the connection housing 9 has wall sections 16 which separate the free spaces from each other and bound laterally. In this way, the connection housing 9 and the spring support 6 in this area in each case form a geometry which is rectangular in plan view. The clamping spring 7 and a to be connected Ladders are so well protected. In particular, such fine-stranded conductors are easily connectable, because the terminal housing rear wall 14, the contact leg 5b of the contact element 5, the clamping leg 7b and the base wall 6a of the spring carrier 6 each form conductor guides, which simplify the insertion of the respective conductor in the terminal point. The base wall 6a is aligned completely or at least almost with the front wall 15 of the connection housing. Such a completely or almost completely closed wall, consisting of the front wall 15 and the one or more base walls are formed. Here, only the gap in which the busbar 8 sits, not formed in the region of the front wall 15 and the base walls 6a closed. The base wall 6a advantageously forms a conductor guide to the side of the front wall 15 out.
Die Leiterführungen liegen jeweils unterhalb (in Z-Richtung) der Leitereinführöffnung 12 im Anschlussgehäuse 9. The conductor guides are each below (in the Z direction) of the conductor insertion opening 12 in the connection housing. 9
Die Anzahl an Einzel-Leiteranschlüssen der Reihenklemme ist einfach variierbar. Es können auch mehrere der Stromschienen 8 mit Leiteranschlüssen in das Anschlussgehäuse 9, insbesondere das Reihenklemmengehäuse, eingesetzt sein. Es ist auch denkbar, die Federträger 6 für mehrere einzelne der Leiteranschlüsse 2, 3, 4 direkt einstückig zu einem einzigen Teil miteinander zu verbinden. In diesem Fall geht die Rückwand über mehrere der Federträger 6 hinweg durch. The number of individual conductor connections of the terminal block is easily variable. It is also possible to use a plurality of the busbars 8 with conductor connections in the connection housing 9, in particular the terminal block housing. It is also conceivable to connect the spring supports 6 for a plurality of individual of the conductor terminals 2, 3, 4 directly in one piece to a single part. In this case, the rear wall passes through several of the spring carrier 6 away.
Im (Reihen-)Klemmengehäuse 9 können im Bereich der Freiräume 10 Leiteran- schluss-Montagemittel vorgesehen sein, die mit korrespondierenden Leiteran- schluss-Montagemitteln an den Leiteranschlüssen - also an der Klemmfeder, dem Federträger 6, dem Kontaktelement 5 und/oder der Stromschiene 8 - zusammenwirken.. Im (Reihen-)Klemmengehäuse 9 können dazu nach einer vorteilhaften Variante im Bereich der Freiräume 10 Zapfen 17 (Fig. 3a) beispielsweise an der Gehäuserückwand 14, vorgesehen sein, die mit korrespondierenden Löchern 20 in Zapfen In the (row) terminal housing 9, 10 conductor connection mounting means can be provided in the region of the free spaces, which with corresponding conductor connection mounting means to the conductor terminals - ie on the clamping spring, the spring support 6, the contact element 5 and / or the busbar 8 (FIG. 3a), for example on the housing rear wall 14, can be provided in the (row) terminal housing 9 according to an advantageous variant in the region of the free spaces provided with corresponding holes 20 in tenons
(und/oder z.B. in der Federhaltekontur 6d, siehe Fig. 3b) der Federträger 6 klemmend oder rastend zusammenwirken. Alternativ (siehe Fig. 4) können auch puzzleartige Vorsprünge 18 vorstehend von der Gehäuserückwand 15 vorgesehen sein, die mit entsprechenden Ausnehmungen 19 im Rand der Stromschiene 8 haltend zusammenwirken. In Fig. 4 sind die Strom- schiene 8 und die Kontaktelemente 5 vormontiert und die Federträger 6 mit den(and / or for example in the spring-retaining contour 6d, see Fig. 3b) of the spring support 6 cooperating clamping or latching. Alternatively (see FIG. 4), puzzle-like projections 18 may also be provided projecting from the housing rear wall 15, which cooperate with corresponding recesses 19 in the edge of the busbar 8. In Fig. 4, the busbar 8 and the contact elements 5 are pre-assembled and the spring carrier 6 with the
Klemmfedern 7. Diese Baugruppen werden zusammengesetzt und dann im Gehäuse 9 montiert. Es ist aber auch denkbar, sie nacheinander dort zu montieren. Ergänzend sind ferner auch hier Vorsprünge 1 1 an den freien Enden der Kontaktelemente 5 ausgebildet. Im Anschlussgehäuse 9 sind mehrere Rastkanten ausgebildet, an de- nen die Vorsprünge 1 1 an den Kontaktelementen 5 verrastbar sind (letzteres hier nicht zu erkennen. Clamping springs 7. These assemblies are assembled and then mounted in the housing 9. But it is also conceivable to mount them one after the other there. In addition, protrusions 11 are also formed here at the free ends of the contact elements 5. In the connection housing 9 a plurality of locking edges are formed, on which the projections 1 1 can be latched to the contact elements 5 (the latter can not be seen here.
Es ist auch denkbar, die Federträger 6 für mehrere einzelne Leiteranschlüsse in Reihe direkt einstückig zu einem einzigen Teil miteinander zu verbinden. In diesem Fall geht die Grundwand über mehrere der Federträger 6 hinweg durch (nicht dargestellt), so dass an diesem mehrere Klemmfedern anordbar sind. It is also conceivable to connect the spring carrier 6 for several individual conductor connections in series directly in one piece to a single part. In this case, the base wall goes through several of the spring carrier 6 away (not shown), so that a plurality of clamping springs can be arranged on this.
