Description

Die Erfindung betrifft einen Leiteranschluß für Hutschienen gemäß Gattungsbegriff des Anspruches 1. Derartige Leiteranschlüsse finden insbesondere Verwendung in Schutzleiterreihenklemmen und dienen dort dem Anschluß des Schutzleiters und dessen elektrischer Verbindung zu der das Nullpotential führenden, als Tragschiene dienenden Hutschiene.The invention relates to a conductor connection for top-hat rails according to the preamble of claim 1. Such conductor connections are used in particular in protective conductor terminal blocks and are used there to connect the protective conductor and its electrical connection to the top-hat rail which serves as a mounting rail.

Bei den bekannten Leiteranschlüssen der gattungsgemäßen Art (DE-U-77 36 440) sind das Stromschienenstück und die Gegenlasche jeweils als U-förmige, zweischenklige Blechbiegeteile ausgeführt, wobei im Bereich oberhalb der Hutschiene das Stromschienenstück im wesentlichen oben über der Gegenlasche liegt, die den unteren Bereich des Stromschienenstückes mit ihren beiden Schenkeln beidseitig umschließt. Mit ihren unteren Endbereichen untergreift die Gegenlasche hakenförmig die Hutschienenschenkel. Die Gegenlasche ist mittels einer Klemmschraube relativ zum Stromschienenstück beweglich und gegen die Unterseite der Hutschienenschenkel klemmbar.In the known conductor connections of the generic type (DE-U-77 36 440), the busbar piece and the mating bracket are each designed as U-shaped, two-leg bent sheet metal parts, the busbar section lying essentially above the mating bracket in the area above the top-hat rail encloses the lower area of the conductor rail piece with its two legs on both sides. With its lower end areas, the counter-plate engages under the top-hat rail legs in a hook-like manner. The counter plate can be moved relative to the conductor rail piece by means of a clamping screw and can be clamped against the underside of the top-hat rail legs.

Die bekannte Ausgestaltung ermöglicht zwar eine zuverlässige Festsetzung des Leiteranschlusses auf der Hutschiene, bedingt jedoch einen relativ hohen Materialeinsatz und führt dadurch, daß Stromschiene und Gegenlasche im wesentlichen übereinander angeordnet sind, auch unter Berücksichtigung der notwendigen mechanischen Festigkeit, zu einer relativ großen Gesamtbauhöhe.Although the known configuration enables the conductor connection to be reliably fixed on the top-hat rail, it requires a relatively high amount of material and thus leads to that busbar and mating bracket are arranged essentially one above the other, even taking into account the necessary mechanical strength, to a relatively large overall height.

Der vorliegenden Erfindung liegt von daher die Aufgabe zugrunde, einen Leiteranschluß zu schaffen, der erheblich niedriger baut und auch einen geringeren Materialaufwand hat.The present invention is therefore based on the object of creating a conductor connection which is considerably lower in construction and also has a lower material expenditure.

Die erfindungsgemäße Lösung ergibt sich aus dem kennzeichnenden Teil des Patentanspruches 1.The solution according to the invention results from the characterizing part of patent claim 1.

Dank der nunmehr einschenkligen Ausbildung von Stromschienenstück und Gegenlasche ist bei diesem Leiteranschluß der Materialeinsatz erheblich reduziert. Dadurch, daß im Bereich oberhalb der Hutschiene das einschenklige Stromschienenstück und die einschenklige Gegenlasche parallel nebeneinander angeordnet sind, ergibt sich eine außerordentlich niedrige Bauhöhe.Thanks to the now single-leg design of the conductor rail piece and counter-link plate, the use of materials is considerably reduced with this conductor connection. The fact that the one-leg conductor rail piece and the one-leg counter bracket are arranged parallel next to one another in the area above the top hat rail results in an extraordinarily low overall height.

Auch eine derartige Ausgestaltung läßt sich so mechanisch stabil auslegen, daß ein sicherer Halt auf der Hutschiene und die Aufnahme ausreichend großer Klemmkräfte gewährleistet sind. Zur weiteren Erhöhung der Stabilität dieses Systemes sowohl bezüglich der Kraftaufnahme wie auch bezüglich der störungsfreien Anklemmung an die Hutschiene sind die in den Unteransprüchen gekennzeichneten weiteren besonderen Ausgestaltungen vorgesehen. Hervorzuheben ist hier die parallelbewegliche Führung der einschenkligen Gegenlasche und des einschenkligen Stromschienenstückes aneinander sowie die Verstärkung der die Hutschienenschenkel untergreifenden Hakenbereiche der einschenkligen Gegenlasche mittels querstehender Abwinklungen.Such an embodiment can also be designed to be mechanically stable in such a way that a secure hold on the top-hat rail and the absorption of sufficiently large clamping forces are ensured. In order to further increase the stability of this system both with regard to the absorption of force and with regard to the trouble-free connection to the top-hat rail, the further special configurations characterized in the subclaims are provided. It should be emphasized here that the parallel movement of the one-leg counter plate and the one-leg conductor rail piece to one another as well as the reinforcement of the hook areas of the one-leg mating bracket under the top hat rail legs by means of transverse bends.

Der Leiteranschluß besteht im wesentlichen aus einem Stromschienenstück 1, einer Gegenlasche 2 sowie einer Klemmschraube 3. Das Stromschienenstück 1 ist als einschenkliges Blechbiegeteil ausgebildet und hat an seinem oberen Ende einstückig über eine Abwinkelung eine kleine Anschlußschiene 4, an der, beispielsweise mittels eines Zugbügelanschlusses oder dergleichen, der Schutzleiter angeschlossen werden kann. In der abgewinkelten kleinen Anschlußschiene ist eine Durchsteckbohrung 5 für den Durchtritt der Klemmschraube 3 vorgesehen. Das Stromschienenstück 1 hat ferner leicht aufgerauhte Auflagezonen 6, die nach der Montage auf der Oberseite der Schenkel 7 einer Hutschiene 8 aufsitzen. Das Stromschienenstück 1 hat ferner benachbart den Auflagezonen 6 außenseitige Führungsnasen 9. Schließlich hat das Stromstück 1 im Bereich des oberen Endes, unterhalb der kleinen Anschlußschiene 4, noch Abwinklungen 10.The conductor connection consists essentially of a busbar section 1, a counter-link 2 and a clamping screw 3. The busbar section 1 is designed as a one-leg bent sheet metal part and has a small connecting rail 4 at its upper end, in one piece via an angled part, on which, for example by means of a tension bracket connection or the like , the protective conductor can be connected. A through hole 5 is provided in the angled small connecting rail for the passage of the clamping screw 3. The conductor rail piece 1 also has slightly roughened support zones 6, which are seated on the top of the legs 7 of a top-hat rail 8 after assembly. The track piece 1 also has adjacent guide lugs 9 adjacent to the support zones 6. Finally, the current piece 1 has bends 10 in the region of the upper end, below the small connecting bar 4.

Die Gegenlasche 2 ist ebenfalls als einschenkliges Blechbiegeteil ausgebildet, das, wie insbesondere die Figuren 2 und 3 zeigen, im Bereich oberhalb der Hutschiene 8 parallel neben dem Stromschienenstück 1 angeordnet ist. Dabei liegt ein oberes Endstück 11 der Gegenlasche 2 hinreichend geführt zwischen den Abwinklungen 10 im Bereich des oberen Endes des Stromschienenstückes 1. Im mittleren Bereich der Gegenlasche 2 ist eine untere Abwinklung 12 vorgesehen, in der sich die Gewindebohrung 13 für die Klemmschraube 3 befindet. An den beiden Außenbereichen der mittleren Zone der Gegenlasche 2 sind Abwinklungen 14 vorgesehen, in denen sich Führungsaussparungen 15 befinden, durch die nach Zusammensetzen von Gegenlasche 2 und Stromschiene 1 die Führungsnasen 9 des Stromschienenstückes 1 hinwegtreten und hierdurch eine parallelbewegliche Führung der beiden Teile aneinander bewirken.The counter link plate 2 is also designed as a one-leg bent sheet metal part which, as shown in particular in FIGS. 2 and 3, is arranged in the area above the top-hat rail 8 parallel next to the busbar piece 1. In this case, an upper end piece 11 of the mating tab 2 is adequately guided between the bends 10 in the region of the upper end of the busbar piece 1. In the central area of the mating tab 2, a lower bend 12 is provided, in which the threaded bore 13 for the clamping screw 3 is located. At the two outer areas of the central zone of the counter-link 2 there are bends 14 in which there are guide recesses 15, through which the guide lugs 9 of the current-rail piece 1 pass away after the counter-link 2 and the busbar 1 have been assembled, thereby causing the two parts to be guided parallel to one another.

Die Gegenlasche 2 ist ferner an ihrem unteren Ende mit die Hutschienenschenkel 7 untergreifenden unteren Hakenbereichen 16 versehen, die zur Erhöhung der Stabilität bezüglich der Aufnahme der Klemmkraft mit querstehenden Abwinklungen 17 versehen sind.
Die Abwinklungen 10 sind ferner zweckmäßig so angeordnet, daß sie die kleine Anschlußschiene 4 unterstützen, da letztere beim Anschluß eines Leiters mit einem von einem Schraubendreher ausgehenden Druck belastet wird.The counter-link 2 is also provided at its lower end with lower hook areas 16 which grip under the top-hat rail legs 7 and which are provided with transverse bends 17 to increase the stability with regard to the absorption of the clamping force.
The bends 10 are also advantageously arranged so that they support the small connecting bar 4, since the latter is loaded with a pressure from a screwdriver when connecting a conductor.
