Abstract

A switch is disclosed for establishing an electric connection between two parts to be connected (4, 5). Conventional switches have a contact lever (1) with a switching contact (2). When the switch is closed, current flows through the contact lever (1). The contact lever (3) must have a low mass inertia for fast switching to take place. This generally results, however, in low current conductivity. The current conducting and contacting functions can be separated by arranging the switching contact (2) on the lever on a separate electric connection device (3). The contact lever (1) thus no longer has any current conducting function and can be exclusively optimised from the mechanical point of view.

Description

SchaltvorrichtungSwitching device
Beschreibung:Description:
Die Erfindung bezieht sich auf eine Schaltvorrichtung gemäß dem Oberbegriff des Patentanspruchs l.The invention relates to a switching device according to the preamble of claim 1.
Fig. 2 zeigt eine Prinzipdarstellung einer Schaltvorrichtung wie beispielsweise eines Gleichstrom-Schnellschalters nach dem Stand der Technik. Die Schaltvorrichtung umfaßt ein erstes und zweites starres Anschlußteil 5, 4 zum Anschließen eines zu schaltenden Stromkreises und einen bewegbaren Kon- takthebel 1, der um eine Drehachse 6 drehbar gelagert ist. Auf dem Kontakthebel 1 befindet sich ein Kontaktplättchen 2 als kontakthebelseitiger Schaltkontakt. Durch Betätigen des Kontakthebels 1 kann ein Kontakt zwischen dem Kontakt- plättchen 2 und einem Schaltkontakt des ersten Anschlußteils 5 hergestellt werden, wodurch der Stromkreis über die beiden Anschlußteile 4 und 5 geschlossen wird (vgl. strichpunktiert dargestellten Schaltzustand in Fig. 2).Fig. 2 shows a schematic diagram of a switching device such as a DC high-speed switch according to the prior art. The switching device comprises a first and a second rigid connecting part 5, 4 for connecting a circuit to be switched and a movable contact lever 1 which is rotatably mounted about an axis of rotation 6. On the contact lever 1 there is a contact plate 2 as a switch contact on the lever side. By actuating the contact lever 1, contact can be made between the contact plate 2 and a switching contact of the first connection part 5, as a result of which the circuit is closed via the two connection parts 4 and 5 (cf. switching state shown in broken lines in FIG. 2).
Gemäß dem Stand der Technik ist das Kontaktplättchen 2 auf dem bewegbaren Kontakthebel 1 befestigt, der über eine bewegliche Verbindung wie beispielsweise ein Flexband 3 mit dem zweiten Anschlußteil 4 elektrisch verbunden ist. Anstelle des Flexbands 3 sind auch Strombolzen, Reibkontakte odgl. als- Verbindungsvorrichtungen zwischen dem Kontakthebel und dem zweiten Anschlußteil 4 möglich. Der zu schaltende Stromkreis wird also im vorliegenden Beispiel gemäß Fig. 2 über die beiden Anschlußteile 4 und 5, den Kontakthebel 1 und das Flexband 3 geschlossen.According to the prior art, the contact plate 2 is fastened on the movable contact lever 1, which is electrically connected to the second connection part 4 via a movable connection, such as a flexible band 3. Instead of the flexible band 3 there are also current bolts, friction contacts or the like. als- connecting devices between the contact lever and the second connecting part 4 possible. The circuit to be switched is thus closed in the present example according to FIG. 2 via the two connecting parts 4 and 5, the contact lever 1 and the flexible band 3.
Kontaktübergangsstellen in Schaltvorrichtungen führen zu erhöhten elektrischen Verlusten und behindern den Wärmefluß. Insbesondere im Bereich sich öffnender Schaltkontakte in Schutzschaltvorrichtungen ist eine optimale Ausgestaltung er- forderlich. Zur Strombegrenzung ist ein schnelles Öffnen der Kontakte nach dem Auftreten eines Kurzschlusses notwendig. Der Kontakthebel ist dabei so auszugestalten, daß er die nachfolgenden mechanischen und elektrischen Anforderungen erfüllt. In mechanischer Hinsicht sollte der Kontakthebel eine möglichst geringe Massenträgheit aufweisen, um dadurch einen schnellen Schaltvorgang zu ermöglichen. Aufgrund einer gefor- derten hohen Stromtragfähigkeit ergeben sich ein möglichst hoher Kontakthebelquerschnitt und ein möglichst geringer spezifischer Widerstand des Kontakthebelmaterials als elektrische Anforderungen.Contact transition points in switching devices lead to increased electrical losses and hinder the flow of heat. In particular in the area of opening switching contacts in protective switching devices, an optimal configuration is required. To limit the current, the contacts must be opened quickly after a short circuit occurs. The contact lever must be designed so that it meets the following mechanical and electrical requirements. From a mechanical point of view, the contact lever should have the lowest possible inertia in order to enable a fast switching process. Due to the high current carrying capacity required, the contact lever cross-section is as large as possible and the specific resistance of the contact lever material is as low as possible as electrical requirements.
Aus den vorgenannten Anforderungen ist jedoch ersichtlich, daß eine Verbesserung der mechanischen Eigenschalten im allgemeinen zu einer Verschlechterung der elektrischen Eigenschaften und umgekehrt führt.However, it can be seen from the aforementioned requirements that an improvement in the mechanical intrinsic switching generally leads to a deterioration in the electrical properties and vice versa.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Schaltvorrichtung mit verbesserten Schalteigenschaften bereitzustellen.It is therefore an object of the present invention to provide a switching device with improved switching properties.
Diese Aufgabe wird gelöst durch eine Schaltvorrichtung gemäß Patentanspruch 1.This object is achieved by a switching device according to claim 1.
Durch das Anordnen des kontakthebelseitigen Schaltkontakts auf der Verbindungsvorrichtung wird erfindungsgemäß die Funktion der Strom- und Wärmeleitung von der Funktion der Kon- taktfuhrung getrennt. Der Kontakthebel übernimmt dabei rein mechanische Führungsaufgaben, so daß die an diesen gestellten Anforderungen hinsichtlich der Stromtragfähigkeit entfallen. Durch die Trennung der Stromleitungsfunktion von der Kontaktführungsfunktion kann der Kontakthebel in leichter Bauweise mit geringer Massenträgheit aus beispielsweise elektrisch nichtleitendendem Material hergestellt werden.According to the invention, the function of the current and heat conduction is separated from the function of the contact guidance by arranging the switching contact on the contact lever side on the connecting device. The contact lever takes on purely mechanical management tasks, so that the demands placed on them with regard to the current carrying capacity are eliminated. By separating the power line function from the contact guide function, the contact lever can be manufactured in a lightweight design with low inertia from, for example, electrically non-conductive material.
Die erfindungsgemäße Ausgestaltung der Schaltvorrichtung ermöglicht die Verwendung einer relativ langen, flexiblen Ver- bindungsvorrichtung wie beispielsweise eines Flexbands 3, wodurch eine Formgebung realisierbar ist, die einen positiven Einfluß auf die Lebensdauer hat. Ferner wird durch die Verringerung der Kontaktübergangsstellen und die direkte Verbindung des hebelseitigen Schaltkontakts mit der Verbindungsvorrichtung eine hohe thermische und elektrische Leitfähigkeit erzielt.The configuration of the switching device according to the invention enables the use of a relatively long, flexible connecting device such as a flexible band 3, whereby a shape can be realized which has a positive influence on the service life. Furthermore, a high thermal and electrical conductivity is achieved by reducing the contact transition points and the direct connection of the lever-side switching contact to the connecting device.
Vorteilhafte Weiterbildungen der vorgenannten Erfindung sind in den Unteransprüchen angegeben.Advantageous developments of the aforementioned invention are specified in the subclaims.
Nachfolgend wird die Erfindung anhand von Ausführungsbeispie- len unter Bezugnahme auf die Zeichnungen näher erläutert. Es zeigen:The invention is explained in more detail below on the basis of exemplary embodiments with reference to the drawings. Show it:

Fig. 1 zeigt eine prinzipielle Darstellung einer erfindungsgemäßen Schaltvorrichtung.1 shows a basic illustration of a switching device according to the invention.
Im Gegensatz zur bekannten Schaltvorrichtung gemäß Fig. 2 ist das Kontaktplättchen 2 direkt auf dem als beweglichen Verbindungsvorrichtung dienenden Flexband 3 angeordnet. Gemäß dem strichpunktiert dargestellten Schaltzustand verläuft der Strompfad bei geschlossener Schaltvorrichtung lediglich über die beiden Anschlußteile 4 und 5 und das Flexband 3. DieIn contrast to the known switching device according to FIG. 2, the contact plate 2 is arranged directly on the flexible band 3 serving as a movable connecting device. According to the switching state shown in dash-dotted lines, the current path only extends over the two connecting parts 4 and 5 and the flexible band 3 when the switching device is closed
Funktion des Kontakthebels 1 ist somit auf die Kontaktführung beschränkt und er kann somit auch aus nichtleitendem Material hergestellt werden. Zudem entfällt die Stromübergangsstelle zwischen dem Flexband 3 und dem Kontakthebel.Function of the contact lever 1 is thus limited to the contact guide and it can thus also be made from non-conductive material. In addition, there is no current transfer point between the flexible band 3 and the contact lever.
Das Flexband wird in seiner Form vorzugsweise so ausgestaltet, daß ein möglichst verschlei-ßarmer Schaltbetrieb ermöglicht wird. Dies kann beispielsweise durch eine geeignete Krümmungsführung und Anbringung an dem zweiten Anschlußteil 4 erreicht werden.The shape of the flexible band is preferably such that switching operation which is as wear-resistant as possible is made possible. This can be done, for example, by a suitable one Curvature and attachment to the second connector 4 can be achieved.
Fig. 3 zeigt eine schematische Ansicht eines konkreten Aus- führungsbeispiels der erfindungsgemäßen Schaltvorrichtung als Gleichstrom-Schnellschalter. Ein flexibles Kupferband 3 ist an seinem unteren Ende mit dem zweiten Anschlußteil 4 so verbunden, daß es zu dem ersten Anschlußteil 5 hin ausgerichtet ist. Das Kupferbands 3 weist eine Vorkrümmung auf, so daß beim Schaltvorgang auftretende, mechanische Spannungen verringert werden. Ferner weist das Kupferband einen Schlitz 8 auf, in den der Kontakthebel 1 teilweise eingepaßt ist. Am oberen Ende des Kupferbands 3 ist ein elektrisch leitendes Kontaktplättchen 2 direkt auf das Kupferband 3 oder einen ge- eigneten Verbindungsträger gelötet. Der obere Bereich des3 shows a schematic view of a specific exemplary embodiment of the switching device according to the invention as a DC high-speed switch. A flexible copper strip 3 is connected at its lower end to the second connection part 4 so that it is aligned with the first connection part 5. The copper strip 3 has a pre-curvature, so that mechanical stresses occurring during the switching process are reduced. Furthermore, the copper tape has a slot 8, in which the contact lever 1 is partially fitted. At the upper end of the copper strip 3, an electrically conductive contact plate 2 is soldered directly onto the copper strip 3 or a suitable connection carrier. The top of the
Kupferbands 3 ist in eine Aussparung des Kontakthebels 1 eingepaßt und zum Erzielen einer massiven elektrischen Verbindung vorzugsweise preßgeschweißt. Am oberen Ende des Kontakthebels 1 ist ein Vorkontakt 7 angebracht, der den Hauptkon- takt bei betriebsmäßigen Schaltungsvorgängen vor Abbrand schützt und damit die Lebensdauer des Hauptkontakts erhöht.Copper strip 3 is fitted into a recess in the contact lever 1 and is preferably pressure-welded to achieve a solid electrical connection. At the upper end of the contact lever 1 there is a pre-contact 7 which protects the main contact from erosion during operational switching operations and thus increases the service life of the main contact.
Zusammenfassend wird eine Schaltvorrichtung zum Schalten einer elektrischen Verbindung zwischen zwei Anschlußteilen of- fenbart.In summary, a switching device for switching an electrical connection between two connection parts is disclosed.
Herkömmliche Schaltvorrichtungen weisen einen Kontakthebel mit einem Schaltkontakt auf , wobei der Stromfluß bei geschlossener Schaltvorrichtung über den Kontakthebel erfolgt. Zum Erzielen eines schnellen Schaltvorgangs ist eine geringe Massenträgheit des Kontakthebels erforderlich. Diese führt jedoch im allgemeinen zu einer geringeren Stromtragfähigkeit.Conventional switching devices have a contact lever with a switching contact, the current flowing through the contact lever when the switching device is closed. A low inertia of the contact lever is required to achieve a fast switching process. However, this generally leads to a lower current carrying capacity.
Durch Anordnen des hebelseitigen Schaltkontakts auf einer ge- sonderten elektrischen Verbindungsvorrichtung ist eine Trennung der Funktion der Stromleitung von der Funktion der Kontaktführung möglich. Da der Kontakthebel somit keine Stromleitungsfunktion mehr aufweist, kann er ausschließlich in mechanischer Hinsicht optimiert werden. By arranging the lever-side switching contact on a special electrical connection device, it is possible to separate the function of the power line from the function of the contact guide. Since the contact lever no longer has a power line function, it can only be optimized in mechanical terms.
