Eine derartige Sammelschienenanordnung ist aus der gattungsgemäßen DE 201 05 501 U1 bekannt. Nach dieser Schrift ist eine metallische Sammelschiene in einem Isolierstoffgehäuse angeordnet, die in einer Reihe hintereinander zunächst einige Schraubanschlüsse für Leiter und dann mehrere Klemmfederanschlüsse aufweist, so dass an nur einer einzigen Sammelschiene auf einfache Weise Leiter verschiedenster Art und verschiedensten Durchmessers anbringbar sind. Durch diese konstruktive Ausgestaltung ist eine sehr schlanke Ausführung gegeben, die auch unter beengten Platzverhältnissen einsetzbar ist. Des weiteren ist durch die vorteilhafte Reihenanordnung der Schraub- und Klemmfederanschlüsse eine individuelle Anpassung an die Erfordernisse gegeben. So kann nach einer bevorzugten Variante durch Ablängen der einen oder anderen Anschlussreihe deren jeweilige Anzahl exakt bestimmt werden. Hierdurch wird zum einen eine optimale Materialnutzung gewährleistet und zum anderen der zur Verfügung stehende Montageplatz in vorbildlicher Weise genutzt.Such a busbar arrangement is known from the generic DE 201 05 501 U1.

Danach schafft die Erfindung eine Sammelschienenanordnung mit einer aus einem Isolierstoff bestehenden Gehäuseanordnung, in der eine Sammelschienenbaugruppe angeordnet ist, wobei in die Stromsammelschiene in deren u-förmigen Bereich eine Leiste eingesetzt ist, die derart ausgestaltet ist, dass sie den Innenraum der Stromsammelschiene (im u-förmigen Bereich) in Klemmkammern unterteilt, wobei jedem Klemmfederanschluss eine der Klemmkammern zugeordnet ist. Durch die derart baulich einfach und kostengünstig realisierte Unterteilung in definierte Klemmkammern ist auf einfache Weise auch ein besonders sichere Beschalten der Klemmfederanschlüsse auch mit sehr dünnen Leitern möglich. Vorzugsweise sind die Klemmfederanschlüsse als werkzeugfrei beschaltbare und mit einem Werkzeug entschaltbare Direktsteckanschlüsse ausgebildet.Thereafter, the invention provides a busbar assembly having a housing assembly consisting of an insulating material, in which a busbar assembly is arranged, wherein in the busbar in the U-shaped portion of a bar is inserted, which is designed such that it the interior of the busbar (in u -shaped area) divided into clamping chambers, each clamping spring terminal is associated with one of the clamping chambers. Due to the structurally simple and inexpensive realized subdivision into defined terminal chambers a particularly secure connection of the clamping spring terminals is also possible with very thin conductors. Preferably, the clamping spring terminals are designed as tool-free connectable and detachable with a tool direct plug-in connections.

Die Gehäuseanordnung 1 weist ein im Querschnitt u-förmiges Grundgehäuse 3 sowie einen darin von oben verrastend einschieb- und festlegbaren Deckel 4 auf.The housing assembly 1 has a cross-sectionally U-shaped base housing 3 and a latching and fixable therein from above cover 4 on.

Das Grundgehäuse 3 ist an einer seiner Längsseiten 5 mit in einer Reihe liegenden Einfiihröffnungen 6, 7 für (hier nicht dargestellte) Leiter versehen, von denen die er sten Öffnungen 6 mit einem größeren Durchmesser zum Einführen von Leitern in die Schraubanschlüsse 8 der Sammelschienenbaugruppe 2 und die zweiten Öffnungen 7 mit einem kleineren Durchmesser zum Einführen von entsprechend dünneren Leitern in die Klemmfederanschlüsse 9 der Sammelschienenbaugruppe 2 dienen (Fig. 3).The base housing 3 is provided on one of its longitudinal sides 5 with in-line Einfiihröffnungen 6, 7 for (not shown here) conductor, of which he The larger diameter holes 6 for inserting conductors into the screw terminals 8 of the bus bar assembly 2 and the smaller diameter second openings 7 for inserting correspondingly thinner conductors into the clamping spring terminals 9 of the bus bar assembly 2 (FIG. 3).

An der Längsseite 5 sind im Bereich jeder Einführöffnungen 6, 7 für die Leiter jeweils Einführkragen 12 ausgebildet, welche von der Längsseite im Bereich jeder Einführöffnung 6, 7 nach außen vorstehen und derart das Einführen der Leiter erleichtern.On the longitudinal side 5 each Einführkragen 12 are formed in the region of each insertion openings 6, 7 for the ladder, which protrude from the longitudinal side in the region of each insertion opening 6, 7 to the outside and thus facilitate the insertion of the conductor.

Im Deckel 4 - der um 90° versetzt zur Längsseite 5 mit den Einführöffnungen 6, 7 für die Leiter liegt, sind jeweils korrespondierende, bevorzugt trichterartige Öffnungen 10, 1 ausgebildet, von denen einige erste Öffnungen 10 zum Einführen eines Schraubendrehers zum Betätigen der Schraubanschlüsse und einige weitere Öffnungen 11 zum Einführen eines Betätigungswerkzeuges zum Öffnen der Klemmfederanschlüsse 9 dienen. Der Deckel 4 erstreckt sich im Grundgehäuse 2 zumindest im Bereich der trichterartigen Öffnungen 10, 11 bis zur Sammel- bzw. Stromschienenbaugruppe 2 und legt diese in dem Grundgehäuse 3 fest.In the cover 4 - which is offset by 90 ° to the longitudinal side 5 with the insertion openings 6, 7 for the conductor, respectively corresponding, preferably funnel-like openings 10, 1 are formed, of which some first openings 10 for inserting a screwdriver for actuating the screw terminals and a few further openings 11 for insertion of an actuating tool for opening the clamping spring terminals 9 are used. The cover 4 extends in the base housing 2 at least in the area of the funnel-like openings 10, 11 to the busbar assembly 2 and sets them in the base housing 3.

Der Aufbau der Sammelschienenbaugruppe 2 erschließt sich am besten aus dem Zusammenspiel der Fig. 3 bis 5.The structure of the busbar assembly 2 is best understood from the interaction of FIGS. 3 to 5.

Wie in Fig. 3 zu erkennen, besteht die Sammelschienenbaugruppe zunächst aus der eigentlichen Stromsammelschiene 13, deren Aufbau hier dem Aufbau der Sammelschiene des gattungsgemäßen Standes der Technik weitgehend entspricht. So sind wiederum die Schraubanschlüsse 8 und die Klemmfederanschlüsse 9 in Längsrichtung der Stromsammelschiene 13 nebeneinander liegend angeordnet mit dem Ziel, daß jeweils die Leitereinführungen der Schraub- und Klemmfederanschlüsse 8, 9 aus einer einzigen Richtung erfolgen können, ebenso wie die Betätigungseinrichtungen für die Klemmschrauben 15 und Klemmfedern 20, bspw. im Winkel von 90° zu den Leitereinführungen.As can be seen in Fig. 3, the busbar assembly initially consists of the actual busbar 13, the structure of which corresponds largely to the structure of the busbar of the generic state of the art here. Thus, in turn, the screw terminals 8 and the clamping spring terminals 9 are arranged side by side in the longitudinal direction of the busbar 13 with the aim that each of the lead entries of the screw and clamping spring terminals 8, 9 can be made from a single direction, as well as the actuators for Clamping screws 15 and clamping springs 20, for example. At an angle of 90 ° to the conductor entries.

Die Schraubanschlüsse 8 sind dabei wiederum nach Art des gattungsgemäßen Standes der Technik ausgebildet, s.h. die Stromsammelschiene ist in diesem Bereich im Querschnitt zu einem einfachen 90° Winkel zurechtgebogen, wobei jeweils in jeden Anschlusskäfig 14 mit Klemmschraube 15 der Schraubanschlüsse 8 ein Kontaktlappen 16 der Stromsammelschiene 2 hineinragt.The screw terminals 8 are again formed in the manner of the generic state of the art, s.h. the busbar is bent in this area in cross section to a simple 90 ° angle, each in each terminal cage 14 with clamping screw 15 of the screw 8 a contact tab 16 of the busbar 2 protrudes.

Eine andere Ausbildung als im Stand der Technik weisen dagegen die Klemmfederanschlüsse 9 auf. In diesem Bereich weist die Stromsammelschiene 13 zunächst wiederum einen U-förmigen Querschnitt auf, wobei am mittleren Schenkel 16 der U-förmigen Sammelschiene jeweils Durchbrüche 17 zum Einführen der Leiter ausgebildet sind, welche mit den Öffnungen 6, 7 im Grundgehäuse fluchten. Im Bereich jedes Durchbruches 17 ist dabei noch aus dem Material der Stromsammelschiene 2 eine Einführzunge 18 herausgebogen, welche das Einführen der Leiter erleichtert.On the other hand, another embodiment than in the prior art has the clamping spring connections 9. In this area, the power bus bar 13 again in turn has a U-shaped cross-section, wherein on the middle leg 16 of the U-shaped busbar respective openings 17 are formed for insertion of the conductors, which are aligned with the openings 6, 7 in the main body. In the area of each opening 17, an insertion tongue 18 is bent out of the material of the busbar 2, which facilitates the insertion of the conductors.

An dem im eingebauten Zustand zum Deckel 4 weisenden Längsschenkel sind zudem Schlitze 19 ausgebildet, welche dem Durchstecken der Spitze eines Schraubendrehes zum Betätigen von Klemmfedern 20 dienen, die jeweils jeder Klemmstelle bzw. jedem Klemmfederanschluss 9 zugeordnet sind.At the in the installed state facing the cover 4 longitudinal leg slots 19 are also formed, which serve to push through the tip of a screwdriver for actuating clamping springs 20, which are each associated with each nip or each terminal spring terminal 9.

Jedem Durchbruch 17 ist dabei eine der Klemmfedern 20 (Fig. 1, Fig. 5) zugeordnet. Die Klemmfedern 20 sind im wesentlichen L-förmig ausgebildet und liegen in dem u-förmigen Bereich der Stromsammelschiene 13 ein (siehe insbesondere Fig. 1), wobei der Längsschenkel 21 der Klemmfedern 20 in sich gebogen ausgebildet ist und den eigentlichen Klemmschenkel bzw. eine Federzunge zum Andrücken des Leiters an die Sammelschiene 13 ausbildet. Die Klemmfederanschlüsse 9 der Stromsammelschiene 13 sind im Leiteranschlussbereich prismenförmig ausgebildet, um beim Anschließen die Leiter selbsttätig in der Klemmstelle zu zentrieren und positionieren.Each breakthrough 17 is assigned one of the clamping springs 20 (FIG. 1, FIG. 5). The clamping springs 20 are substantially L-shaped and lie in the U-shaped region of the busbar 13 (see in particular Fig. 1), wherein the longitudinal leg 21 of the clamping springs 20 is formed bent and the actual clamping leg or a spring tongue for pressing the conductor to the busbar 13 is formed. The clamping spring terminals 9 of the busbar 13 are prism-shaped in the conductor connection area, in order to center and position the conductors automatically in the nip during connection.

Um im Innenbereich der u-förmig gebogenen Stromsammelschiene 13 definierte Klemmstellen auszubilden, in denen auch ein Beschalten mit besonders dünnen Leitern möglich ist und um auf einfache Weise die Klemmfedern 20 festzulegen und für die Leiter genau zu definieren, ist in die Stromsammelschiene 13 eine Leiste 22 (Fig. 1, Fig. 4) eingesetzt, welche hier an beiden Längsaußenseiten 24 oder zumindest an ihrer dem einzuführenden Leiter zugewandten Seite mit mehreren Wandabschnitten 26 versehen ist, deren Abstand dem Abstandraster der Klemmfederanschlüsse 9 entspricht und die derart ausgebildet und angeordnet sind, dass der Innenraum der Stromsammelschiene im u-förmigen Bereich bzw. im Bereich der Klemmfederanschlüsse 9 in definierte Klemmkammern 23 unterteilt wird, in denen jeweils eine der Klemmfedern 20 aufgenommen und fixiert ist.In order to form 13 defined clamping points in the interior of the U-shaped current busbar, in which a wiring with very thin conductors is possible and to easily determine the clamping springs 20 and define the conductor exactly, is in the busbar 13 a bar 22nd (Fig. 1, Fig. 4) used, which is here provided on both longitudinal outer sides 24 or at least on its the conductor to be inserted facing side with a plurality of wall portions 26 whose distance corresponds to the pitch of the clamping spring terminals 9 and which are formed and arranged such that the interior of the busbar in the u-shaped region or in the region of the clamping spring terminals 9 is subdivided into defined clamping chambers 23, in each of which one of the clamping springs 20 is received and fixed.

Die Klemmfederanschlüsse 9 mit den Klemmfedern 20 sind wahlweise werkzeuglos durch das Einführen der Leiter oder mit Hilfe eines Betätigungswerkzeuges beschaltbar. Das Entschalten erfolgt mit Hilfe des Betätigungswerkzeuges. Die Leiste 22 ist dabei in dem Bereich zwischen den Wandabschnitten derart ausgebildet, dass sie für die Klemmfedern 20 jeweils eine definierte Federwegbegrenzung ausbildet, so dass ein Überdehnen oder ein Beschädigen der Klemmfedern 20 insbesondere beim Öffnen zum Ausnehmen der Leiter vermieden wird. Die Kontur der Leiste 22 - die vorzugsweise aus Isolierstoff besteht - ist dabei derart zur Kontur der Klemmfedern 20 ausgebildet und ausgerichtet, dass sie eine optimale Anlagekontur für die Klemmfeder 20 und eine sich von der Einführöffnung 6, 7 fort verjüngende Klemmkammer ausbildet.The clamping spring terminals 9 with the clamping springs 20 can optionally be connected without tools by inserting the ladder or with the aid of an actuating tool. The disconnection takes place with the aid of the actuating tool. The strip 22 is formed in the region between the wall sections in such a way that it forms a defined suspension travel limit for the clamping springs 20, so that overstretching or damaging of the clamping springs 20, in particular when opening to remove the conductors, is avoided. The contour of the strip 22 - which preferably consists of insulating material - is designed and aligned in such a way to the contour of the clamping springs 20 that it forms an optimal contact contour for the clamping spring 20 and from the insertion opening 6, 7 further tapered clamping chamber.
