Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung bezieht sich auf das Gebiet der Niederspannungsverteiler des Stecksockeltyps. Sie betrifft ein Steckmodul und insbesondere ein Einspeiseelement für Stecksockelsysteme gemäss dem Oberbegriff des Patentanspruchs 1.The present invention relates to the field of low-voltage distributors of the socket type. It relates to a plug-in module and in particular a feed element for plug-in socket systems according to the preamble of patent claim 1.

STAND DER TECHNIKSTATE OF THE ART

Niederspannungsverteiler des Stecksockeltyps umfassen ein Strom- oder Sammelschienen aufnehmendes Stecksockelsystem, auf welches modularisierte Steckteile, wie Einspeise- und Abgangselemente oder Schalt- und Schutzgeräte mit unterschiedlichsten Funktionen, aufgesteckt werden. Solche Niederspannungsverteiler ermöglichen eine zeit- und kostensparende Planung und Ausführung eines Verteilers und zeichnen sich durch rasche Herstellbarkeit, einfache Einspeisung und problemlose Auswechselbarkeit der Steckteile aus.Low-voltage distributors of the plug-in socket type include a plug-in socket system receiving current or busbars, onto which modularized plug-in parts, such as feeder and outgoer elements or switching and protective devices with a wide variety of functions, are plugged. Such low-voltage distributors allow a time and cost-saving planning and execution of a distributor and are characterized by rapid manufacturability, easy feed and easy replaceability of the male parts.

Ein derartiges, unter der Bezeichnung "smissline-S" bekanntes Stecksockelsystem mit unterschiedlichen Schutzgeräten zur modularen Energieverteilung bis 160 A Nennstrom ist beispielsweise aus dem technischen Katalog 20160/A "Innovation mit System" der Firma ABB CMC Components, Zürich/Schweiz, bekannt. Das System umfasst zumindest einen Hauptstecksockel zur Aufnahme von sechs Stromschienen für die drei Phasen und einen Neutralleiter sowie zwei Hilfsschienen. Die Speisung der Sammelschienen erfolgt über ein Einspeiseelement, welches aus EP-A 229 590 bekannt ist, und in welches vier Zuleitungen oder Speiseleiter eingeführt und durch Einspeiseklemmen festgeschraubt werden. Diese Einspeiseklemmen sind unmittelbar mit auf die Schienen aufgesteckten Steckkontakten verbunden. Infolge der beträchtlichen, auf die Nennströme ausgelegten Speiseleiterquerschnitte sind die Speiseleiter und die Einspeiseklemmen nebeneinander angeordnet, und die Breite des Einspeiseelements entspricht einer vierfachen Einheitsbreite.Such, under the name "smissline-S" known socket system with different protection devices for modular power distribution up to 160 A rated current, for example, from the technical catalog 20160 / A "Innovation with System" ABB CMC Components, Zurich / Switzerland, known. The system comprises at least one main socket for accommodating six busbars for the three phases and a neutral conductor and two auxiliary rails. The supply of the busbars via a feed element, which consists of EP-A 229 590 is known, and in which four leads or feeders are introduced and tightened by power terminals. These supply terminals are directly connected to plugged onto the rails plug contacts. Due to the considerable feed conductor cross sections designed for the rated currents, the feeders and the feed terminals are arranged side by side, and the width of the feed element is four times the unit width.

In der noch unveröffentlichten Europäischen Patentanmeldung 01810851.4 ist ein Steckmodul mit nebeneinander angeordneten Steckkontakten als Bestandteil eines Steckteils, d.h. eines beliebigen Apparats, Geräts, Einspeise- oder Abgangselements, offenbart. Beim Aufstecken des Steckmoduls auf das Stecksockelsystem wird Ersteres um eine Achse geschwenkt und in den Stecksockel eingerastet, wobei die Steckkontakte mit den Strom- oder Sammelschienen einen ausgezeichneten elektrischen Kontakt bilden.In the still unpublished European patent application 01810851.4 is a plug-in module with juxtaposed plug contacts as part of a male part, ie any apparatus, device, feed or outlet element disclosed. When plugging the plug-in module on the socket system, the former is pivoted about an axis and locked into the socket, the plug contacts with the power or busbars form an excellent electrical contact.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Aufgabe der vorliegenden Erfindung ist es, ein Steckmodul für Stecksockelsysteme und insbesondere ein Einspeiseelement anzugeben, welches weniger breit ist, d.h. in eine Richtung parallel zu den Stromschienen eine geringere Ausdehnung aufweist als bisher bekannte Elemente oder Geräte mit derselben Funktion. Diese Aufgabe wird durch ein Steckmodul für Stecksockelsysteme mit den Merkmalen des Patentanspruchs 1 gelöst.The object of the present invention is to provide a plug-in module for plug-in socket systems and in particular a feed element which is less wide, i. in a direction parallel to the busbars has a smaller extent than previously known elements or devices with the same function. This object is achieved by a plug-in module for socket system with the features of claim 1.

Kern der Erfindung ist es, die einzelnen Anschlüsse nicht alle nebeneinander, sondern paarweise hintereinander anzuordnen. Jeder Anschluss umfasst einen Steckkontakt sowie einen zur Aufnahme eines Anschlussleiters vorgesehenen Schraubkontakt, es befinden sich also je zwei Steck- und Schraubkontakte senkrecht zu den Stromschienen auf einer Linie. Dadurch wird die Gesamtbreite des Steckmoduls um einen Faktor zwei reduziert.The essence of the invention is not the individual connections next to each other, but in pairs to arrange one behind the other. Each connection comprises a plug-in contact and a screw-type contact intended for receiving a connecting conductor, so there are two plug-in and screw contacts per line perpendicular to the busbars. This reduces the total width of the plug-in module by a factor of two.

Sind insgesamt vier Anschlüsse vorhanden zur Kontaktierung von drei Phasenleitern und eines Neutralleiters, so bilden je zwei hintereinander angeordnete Anschlüsse ein Anschlusspaar, wobei die resultierenden zwei Anschlusspaare wiederum nebeneinander angeordnet sind und somit eine optimale Platzausnutzung ermöglichen. Da jedoch jeder Steckkontakt eine andere Stromschiene kontaktiert, sind die zwei Anschlusspaare senkrecht zu den Stromschienen gegeneinander versetzt.If a total of four connections are present for contacting three phase conductors and one neutral conductor, then two connections arranged one behind the other form a connection pair, with the resulting two pairs of connections being arranged next to one another and thus allowing optimum space utilization. However, since each plug contact a different busbar contacted, the two pairs of terminals are perpendicular to the busbars offset from each other.

Insbesondere bei Einspeiseelementen sind die genannten Anschlüsse mit Speiseleitern verbunden, welche einen grossen Leiterquerschnitt für grosse Nennströme aufweisen. Solche Speiseleiter lassen sich nicht oder zumindest nur unter grossem Aufwand biegen, es ist daher wichtig, sie möglichst geradlinig zu den jeweiligen Anschlüssen zu führen. Zudem sollen alle Speiseleiter wahlweise von der einen oder anderen Breitseite des Einspeiseelements zu den Anschlüssen geführt werden beziehungsweise als durchgehende Leiter ausgeführt sein können. Dies wird erreicht, indem die Anschlüsse höhenversetzt angeordnet sind. Ein längerer, mit einem hinteren Anschluss verbundener Speiseleiter führt entweder in gerader Linie über einen vorderen Anschluss hinweg oder durch eine tunnelförmige Öffnung unter dessen Schraubkontakt hindurch.In particular in the case of feed elements, the abovementioned connections are connected to feeders which have a large conductor cross-section for large nominal currents. Such feeders can not be bent or at least only with great effort, it is therefore important to guide them as straight as possible to the respective connections. In addition, all feeders should either be guided by the one or the other broad side of the feed element to the terminals or can be designed as a continuous conductor. This is achieved by the connections are arranged offset in height. A longer feed conductor connected to a rear connection leads either in a straight line over a front terminal or through a tunnel-shaped opening under its screw through.

Ein Einspeiseelement umfasst ein erfindungsgemässes Steckmodul als Träger und ein Isolierstoffgehäuse, welches als Abdeckhaube mit ersterem verschraubt wird. Zur Einführung der Speiseleiter ins Innere des Elements sind in den Gehäusebreitseiten Durchbruchstellen vorgesehen, bei welchen die Gehäusewand sich einfach und irreversibel entfernen lässt.A feed element comprises a plug-in module according to the invention as a carrier and an insulating material housing which is screwed to the former as a cover hood. For the introduction of the feeders inside the element breakthrough points are provided in the housing sides, in which the housing wall can be easily and irreversibly removed.

Gemäss einer bevorzugten Ausführungsform des erfindungsgemässen Steckmoduls umfasst der Schraubkontakt einen beweglichen, elektrisch leitfähigen Kontaktbügel, welcher mittels einer Schraube auf den Anschlussleiter gedrückt wird und diesen kontaktiert. Dementsprechend sind der Schraub- und der Steckkontakt durch einen flexiblen Kontaktleiter miteinander leitend verbunden, welcher bevorzugt an eine seitliche Lasche des Kontaktbügels angeschweisst ist. Der Kontaktbügel ist einstückig ausgebildet und gleichzeitig für das Festklemmen und Kontaktieren des Anschlussleiters verantwortlich; diese Funktionen werden bei aus dem erwähnten Stand der Technik bekannten Einspeiseklemmen durch mindestens zwei verschiedene Teile wahrgenommen.According to a preferred embodiment of the plug-in module according to the invention, the screw contact comprises a movable, electrically conductive contact clip, which is pressed by means of a screw onto the connecting conductor and contacts it. Accordingly, the screw and the plug contact are conductively connected to each other by a flexible contact conductor, which is preferably welded to a side flap of the contact clip. The contact clip is formed in one piece and at the same time responsible for clamping and contacting the connection conductor; these functions are perceived in known from the cited prior art feed terminals by at least two different parts.

Der klammerförmige Kontaktbügel durchdringt einen Käfig und umfasst gleichzeitig die Schraube derart, dass Letztere nicht vollständig gelöst werden kann und somit nicht verlorengeht. Er ist so ausgebildet, dass durch ein reversibles Verbiegen die Schraube eingesetzt werden kann. Als Material für den Kontaktbügel, welches eine ausreichende Elastizität aufweist, gleichzeitig elektrisch leitfähig ist und ein Anschweissen des Kontaktleiters erlaubt sowie problemlos gestanzt und gebogen werden kann, ist Federbronze (CuSn6) oder, in geringerem Mass, Federstahl geeignet.The clamp-shaped contact clip penetrates a cage and at the same time comprises the screw in such a way that the latter can not be completely released and thus is not lost. It is designed so that the screw can be inserted by a reversible bending. As a material for the contact clip, which has sufficient elasticity, is simultaneously electrically conductive and allows welding of the contact conductor and can be punched and bent easily, spring bronze (CuSn6) or, to a lesser extent, spring steel is suitable.

Weitere vorteilhafte Ausführungsformen gehen aus den abhängigen Ansprüchen hervor.Further advantageous embodiments will become apparent from the dependent claims.

Grundsätzlich sind gleiche Teile mit denselben Bezugszeichen versehen.The reference numerals used in the drawings are summarized in the list of reference numerals. Basically, the same parts are provided with the same reference numerals.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS FOR CARRYING OUT THE INVENTION

In Fig.1 und Fig.2 ist in Schrägaufsicht ein Steckmodul nach der Erfindung mit einem Isolierstoffkörper 1 und vier Anschlüssen dargestellt, wovon jedoch nur die zwei dem Betrachter zugewandten Anschlüsse 2,2' und deren Komponenten mit Bezugszeichen versehen sind. In Fig.2 sind der Isolierstoffkörper 1 und der vom Betrachter aus gesehen rechtsliegende Anschluss 2' im Schnitt dargestellt.In Fig.1 and Fig.2 Schrägaufsicht a plug-in module according to the invention with an insulating body 1 and four terminals is shown, of which, however, only the two facing the viewer ports 2,2 'and their components are provided with reference numerals. In Fig.2 are the Isolierstoffkörper 1 and the viewer from the right-most terminal 2 'shown in section.

Jeder Anschluss 2,2' umfasst je einen Steckkontakt 20,20' und einen Schraubkontakt 21,21', welche mittels eines schraffiert dargestellten Kontaktleiters 22,22' miteinander dauerhaft elektrisch leitend verbunden sind. Der Schraubkontakt 21,21' umfasst einen Käfig 210,210' aus einem elektrisch isolierenden Material, welcher fest mit dem Isolierstoffkörper 1 verbunden ist, einen Kontaktbügel 212,212' aus einem elektrisch leitfähigen Material und eine Schraube 216,216'. Der Käfig 210,210' bildet einen auf vier Seiten geschlossenen Raum. Die beiden einander gegenüberliegenden offenen Seiten dieses Raums definieren eine Kontaktrichtung 3. Ein Ende eines nicht zum Modul gehörigen Anschlussleiters 4,4' führt parallel zur Kontaktrichtung 3 in den besagten Raum.Each terminal 2,2 'each comprises a plug contact 20,20' and a screw 21,21 ', which are connected by means of a hatched illustrated contact conductor 22,22' permanently electrically conductive. The screw 21,21 'comprises a cage 210,210' of an electrically insulating material, which is fixedly connected to the insulating body 1, a contact clip 212,212 'of an electrically conductive material and a screw 216,216'. The cage 210, 210 'forms a space enclosed on four sides. The two opposite open sides of this space define a contact direction 3. One end of a not belonging to the module connecting conductor 4,4 'leads parallel to the contact direction 3 in the said space.

Der Kontaktbügel 212,212' wird mittels der Schraube 216,216' linear nach unten zum Isolierstoffkörper 1 hin bewegt und klemmt das Ende des Anschlussleiters 4,4' zwischen einem Boden des Käfigs 210,210' und dem Kontaktbügel 212,212' fest. Die Bewegung des Kontaktbügels 212,212' wird durch den Käfig 210' und die in ein Gewinde 211' in einer Decke des Käfigs 210' eingeschraubte Schraube 216' geführt (nur in der Schnittdarstellung des Anschluss 2' in Fig.2 ersichtlich). Der Steckkontakt 20,20' weist ein tulpenförmiges Profil auf, und um den Kontaktwiderstand zwischen ihm und einer Stromschiene weiter zu verringern, ist zusätzlich ein die Federkraft des Steckkontaktes 20,20' erhöhender Spannring 200,200' vorgesehenThe contact clip 212, 212 'is moved linearly downwardly toward the insulating body 1 by means of the screw 216, 216' and clamps the end of the connecting conductor 4, 4 'between a bottom of the cage 210, 210' and the contact clip 212, 212 '. The movement of the contact clip 212, 212 'is guided by the cage 210' and the screw 216 'screwed into a thread 211' in a ceiling of the cage 210 '(only in the sectional view of the connection 2' in FIG Fig.2 visible). The plug-in contact 20,20 'has a tulip-shaped profile, and to further reduce the contact resistance between it and a busbar, in addition, a spring force of the plug-in contact 20,20' increasing clamping ring 200,200 'is provided

In Fig.3 ist ein erfindungsgemässer klammerförmiger Kontaktbügel 212 nochmals separat gezeigt. Zwischen einem Kontaktabschnitt 213 und zwei parallel dazu angeordneten Flügelenden wird die Schraube eingeklemmt. Die beiden Flügel 214 sind durch eine schlitzartige Ausnehmung getrennt. Der Kontaktbügel 212 ist aus einem elastischen oder federnden Material gefertigt, so dass die beiden Fügel 214 zur Einführung der Schraube zur Seite gebogen werden können und anschliessend ihre in Fig.3 gezeigte Position wieder einnehmen und die Schraube fixieren. Weiter weist der Kontaktbügel 212 eine seitliche Lasche 215 auf, welche an den Kontaktabschnitt 213 anschliesst und sich parallel zur Kontaktrichtung 3 ausgerichtet ausserhalb des Käfigs befindet.In Figure 3 a clip-shaped contact clip 212 according to the invention is again shown separately. Between a contact portion 213 and two wing ends arranged parallel thereto, the screw is clamped. The two wings 214 are separated by a slot-like recess. The contact clip 212 is made of an elastic or resilient material, so that the two fins 214 for insertion the screw can be bent to the side and then their in Figure 3 take the position shown and fix the screw. Furthermore, the contact clip 212 has a lateral tab 215, which adjoins the contact section 213 and is aligned outside the cage parallel to the contact direction 3.

An jede Lasche 215,215' ist der zugeordnete Kontaktleiter 22,22' angeschweisst. Da der Kontaktbügel 212,212' sich beim Festklemmen des Anschlussleiters 4,4' bewegt, ist der Kontaktleiter 22,22' vorteilhafterweise ein flexibler Leiter oder eine Litze. Am anderen Ende ist der Kontaktleiter 22,22' an den Steckkontakt 20,20' angeschweisst.At each tab 215,215 'the associated contact conductor 22,22' is welded. Since the contact clip 212, 212 'moves when clamping the connection conductor 4, 4', the contact conductor 22, 22 'is advantageously a flexible conductor or a stranded wire. At the other end of the contact conductor 22,22 'to the plug contact 20,20' welded.

Alles bisher Gesagte trifft auf ein beliebiges Steckmodul nach der Erfindung zu. Ist das Steckmodul als Adapter Teil eines Schalt- oder Schutzgerätes mit Zusatzfunktionen, so führen die Anschlussleiter zu einem in den Figuren nicht dargestellten Funktionsmodul. Dieses kann oberhalb oder neben den Anschlüssen, innerhalb derselben Gehäuseeinheit angeordnet sein.Everything so far applies to any plug-in module according to the invention. If the plug-in module as an adapter is part of a switching or protective device with additional functions, then the connecting leads lead to a functional module not shown in the figures. This can be arranged above or next to the terminals, within the same housing unit.

Ist das Steckmodul wie in den Zeichnungen dargestellt ein Teil eines Einspeiseelementes, so werden die Anschlussleiter 4,4' als Speiseleiter bezeichnet, sie führen in diesem Falle ohne den Umweg über ein weiteres Funktionsmodul unmittelbar aus dem Einspeiseelement. Ihr Leiterquerschnitt ist unter Umständen für grosse Nennströme ausgelegt und dementsprechend recht dick (beispielsweise 16 mm2 für 63 A), so dass derartige Speiseleiter sich nicht gut biegen lassen. Um in diesem Fall die Speiseleiter auf einem möglichst geradlinigen Weg zu den in Kontaktrichtung 3 hintereinanderliegenden Anschlüssen 2,2' zu bringen, sind diese in der Höhe versetzt. Ein zum hinteren Anschluss führender Speiseleiter 4 kann somit entweder über den vorderen Anschluss hinwegführen, oder, wie in Fig.1 gezeigt, durch eine geeignete tunnelförmige Ausnehmung 217' unterhalb des Schraubkontaktes 21' des vorderen Anschlusses 2' geführt sein.If the plug-in module, as shown in the drawings, forms part of a feed element, then the connection conductors 4, 4 'are referred to as a feed conductor; in this case they lead directly from the feed element without the detour via another functional module. Their conductor cross-section may be designed for large nominal currents and accordingly quite thick (for example, 16 mm 2 for 63 A), so that such feeders can not bend well. In order to bring in this case, the feeders on a straight path as possible to the consecutive in the contact direction 3 terminals 2,2 ', these are offset in height. A feed conductor 4 leading to the rear connection can thus lead either past the front connection or, as in FIG Fig.1 shown, be guided by a suitable tunnel-shaped recess 217 'below the screw 21' of the front terminal 2 '.

In Fig.4 ist ein Einspeiseelement dargestellt, welches durch ein Isolierstoffgehäuse 5 abgeschlossen ist. Zur Einführung der Speiseleiter 4,4' ins Innere des Elements ist in der dem Betrachter zugewandten Breit- oder Frontseite des Isolierstoffgehäuses 5 eine Öffnung 50 ausgebrochen. Erfindungsgemässe Isolierstoffgehäuse 5 sind ursprünglich, d.h. bevor sie zum Einsatz kommen, im Bereich der potentiellen Durchbruchstellen derart präpariert, dass sich dort die Gehäusewand einfach und irreversibel entfernen lässt. Dazu ist der Rand der Durchbruchstellen als Perforation oder Kerbe ausgebildet oder wird durch vorgängiges Ritzen mit einem spitzen Gegenstand entsprechend vorbereitet. Falls alle Speiseleiter auf derselben Gehäusebreitseite in das Isolierstoffgehäuse 5 eintreten, wird nur dort die Gehäusewand geöffnet, während die zum selben Zweck vorgesehenen Durchbruchstellen der gegenüberliegenden Gehäusebreitseite als Abdeckung und Berührungsschutz bestehen bleibt. Im Falle eines durchgehenden Speiseleiters, d.h. bei einer sogenannten Steigleitung, werden bei beiden Gehäusebreitseiten Öffnungen 50 ausgebrochen.In Figure 4 is a feed element shown, which is completed by an insulating 5. To introduce the feeders 4, 4 'into the interior of the element, an opening 50 has been broken in the broad or front side of the insulating material housing 5 facing the observer. Inventive insulating housing 5 are originally, ie before they are used, in the area of the potential breakdown points prepared in such a way that there can be easily and irreversibly remove the housing wall. For this purpose, the edge of the break-through points is formed as a perforation or notch or is prepared by prior scratches with a sharp object accordingly. If all feeders on the same side of the housing enter the insulating housing 5, only there, the housing wall open, while provided for the same purpose breakthrough points of the opposite side of the housing remains as a cover and protection against contact. In the case of a continuous feeder, ie in a so-called riser, openings 50 are broken at both sides of the housing.
