Description

Die Erfindung betrifft ein Schaltgerät gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a switching device according to the preamble of patent claim 1.

Es sind sog. Installationsrelais bekannt, mit welchen das Schalten eines oder mehrerer Laststromkreise mittels eines leistungsschwachen Steuerstromes möglich ist. Der betreffende Laststromkreis ist dabei geschlossen, solange der Steuerstrom an dem Schaltgerät anliegt. Auch wenn an diesem Steuerstrom in der Regel nur eine geringe Spannung anliegt und nur ein geringer Strom fließt, führt dieser mit der Zeit zu einer nicht unerheblichen Erwärmung. Hinzu kommt bei den bekannten Installationsrelais eine deutlich wahrnehmbare Geräuschentwicklung durch die Spulen des Steuerstromkreises. Dabei handelt es sich um ein Netzbrummen. Konstruktive Feinabstimmungen des Magnetkreises des Installationsrelais zeigten keine zufrieden stellenden Ergebnisse beim Einsatz derart abgestimmter Installationsrelais in unterschiedlichen elektrischen Umgebungen.So-called installation relays are known with which it is possible to switch one or more load circuits by means of a low-power control current. The relevant load circuit is closed as long as the control current is applied to the switching device. Even if only a low voltage is applied to this control current and only a low current flows, this leads to a not inconsiderable warming over time. In addition, with the known installation relays, there is a clearly perceptible noise development from the coils of the control circuit. This is a mains hum. Constructive fine-tuning of the magnetic circuit of the installation relay did not show satisfactory results when using installation relays matched in this way in different electrical environments.

Die EP 641 003 A1 beschreibt ein bistabiles elektromagnetisches Relais, welches einem Schaltgerät gemäß dem Oberbegriff des Patentanspruches 1 entspricht. Die US 2015/155121 A1 beschreibt ein separates Relaisgehäuse in einem Gehäuse.The EP 641 003 A1 describes a bistable electromagnetic relay which corresponds to a switching device according to the preamble of claim 1.

The EP 2 431 993 A1 describes a switching device with a replaceable relay which, however, does not comprise a separate relay housing.

Aus der DE 198 36 549 A1 geht ein elektrischer Apparat mit einem Grundkörper hervor, welcher Polpfade mit trennbaren Kontakten und zugeordnete Unterbrecherkammern aufweist, sowie einen elektromagnetischen Block, welcher die Umschaltungen im Schützmodus sicherstellt, und einem Steuerblock, welcher die Fehleröffnungen bewirkt. Der Apparat ist anwendbar auf eine variable Zusammenstellung durch Zusammenbau verschiedener Steuerblöcke und elektromagnetischer Blöcke auf dem Grundkörper.From the DE 198 36 549 A1 shows an electrical apparatus with a base body, which has pole paths with separable contacts and associated interrupter chambers, as well as an electromagnetic block, which ensures switching in the contactor mode, and a control block, which causes the fault openings. The apparatus is applicable to a variable arrangement by assembling various control blocks and electromagnetic blocks on the base body.

Das erste und das zweite Relais 7, 20 weisen in deren nicht dargestellten Inneren in an sich bekannter Weise jeweils eine Spule auf, welche mit den jeweiligen Relais-Steueranschlüssen 9, 10, 24, 25 verbunden ist, sowie einen Anker, welcher mit Arbeitskontakten des Relais 7, 20 verbunden ist.The first and the second relay 7, 20 have in their interior, not shown, each in a known manner, which is connected to the respective relay control connections 9, 10, 24, 25, as well as an armature, which with normally open contacts of the Relay 7, 20 is connected.

Das Schaltgerät 1 weist einen Druckknopf 13 auf, welcher bevorzugt verschiebbar aus einer Frontseite des Schaltgerätegehäuses 6 ragt. Der Druckknopf 13 wirkt mechanisch mit einem Anker des ersten Relais 7 derart zusammen, dass eine Betätigung des Druckknopfes 13 den Anker betätigt. Dadurch können die Arbeitskontakte des wenigstens einen Relais 7, 20 mechanisch, daher auch ohne das Anliegen einer Steuerspannung, geschlossen bzw. geöffnet werden. Dies ermöglicht die Betätigung des Schaltgeräts 1, etwa zu Testzwecken, unmittelbar an dem Schaltgerät 1. Bei der dargestellten Ausführungsform ist vorgesehen, dass der Druckknopf 13 auf beide Relais 7, 20 bzw. deren Anker wirkt.The switching device 1 has a push button 13, which protrudes preferably displaceably from a front side of the switching device housing 6. The push button 13 interacts mechanically with an armature of the first relay 7 in such a way that actuation of the push button 13 actuates the armature. Thereby the working contacts of the at least one relay 7, 20 can be closed or opened mechanically, therefore even without the application of a control voltage. This enables the switching device 1 to be actuated, for example for test purposes, directly on the switching device 1. In the embodiment shown, it is provided that the push button 13 acts on both relays 7, 20 or their armatures.

Es ist vorgesehen, dass das erste Relaisgehäuse 8 eine erste Öffnung 14 aufweist. Diese erste Öffnung 14 wird von einem ersten Fortsatz 15 durchgriffen bzw. durchragt, welcher erste Fortsatz 15 mit dem Druckknopf 13 zusammenwirkt, sodass durch einer vorgebbaren Bewegung des Druckknopfes 13 auch der erste Fortsatz 15 bewegt wird.It is provided that the first relay housing 8 has a first opening 14. This first opening 14 is penetrated or penetrated by a first extension 15, which first extension 15 interacts with the push button 13 so that the first extension 15 is also moved by a predeterminable movement of the push button 13.

Bei der dargestellten bevorzugten Ausführungsform ist entsprechend vorgesehen, dass das zweite Relais 20 eine zweite Öffnung 29 aufweist, welche von einem zweiten Fortsatz 30 durchgriffen wird. Es kann dabei jeweils vorgesehen sein, dass der erste bzw. der zweite Fortsatz 15, 30 die jeweilige Öffnung 14, 29 nur während einer Betätigung durch den Druckknopf 13 durchgreift.In the preferred embodiment shown, provision is accordingly made for the second relay 20 to have a second opening 29 through which a second extension 30 extends. It can be provided in each case that the first and the second extension 15, 30 reach through the respective opening 14, 29 only when the push button 13 is actuated.

Der erste Fortsatz 15 ist derart in dem Schaltgerät 1 angeordnet, dass eine Betätigung des Druckknopfes 13, insbesondere eine Verschiebung des Druckknopfes 13 in das Schaltgerät 1, den ersten Fortsatz 15 auf den Anker des ersten Relais 7 drückt, und derart manuell eine leitende Verbindung vom ersten Schaltgerät-Lastanschluss 4 zum zweiten Schaltgerät-Lastanschluss 5 gebildet wird. Entsprechendes gilt bei der dargestellten Ausführungsform auch für den zweiten Fortsatz 29 und das zweite Relais 20.The first extension 15 is arranged in the switching device 1 in such a way that an actuation of the push button 13, in particular a displacement of the push button 13 in the switching device 1, presses the first extension 15 onto the armature of the first relay 7, and so manually a conductive connection from first switching device load connection 4 is formed to the second switching device load connection 5. The same applies in the illustrated embodiment to the second extension 29 and the second relay 20.

Die erste bzw. die zweite Öffnung 14, 29 wird an dem ansonst verschlossenen ersten bzw. zweiten Relaisgehäuse 8, 21 an geeigneter Stelle angebracht, um durch deren Bewegung den Anker innerhalb des jeweiligen Relais 7, 20 bewegen zu können.The first or the second opening 14, 29 is attached to the otherwise closed first or second relay housing 8, 21 at a suitable point in order to be able to move the armature within the respective relay 7, 20 by their movement.

Der erste Fortsatz 15 und gegebenenfalls der zweite Fortsatz 30 sind an einem, längs verschiebbar innerhalb des Schaltgerätegehäuses 6 gelagerten Schieber 16 angeordnet. Der Schieber 16 ist dabei bevorzugt mittels eines Hebelarms 17 mit dem Druckknopf 13 verbunden. Dadurch ist eine Betätigung des ersten bzw. zweiten Ankers des jeweiligen Relais 7, 20 möglich, wobei eine gewisse Freiheit bei der Platzierung des Druckknopfes 13 gegeben ist. Durch den Hebelarm 17 kann auch ein Übersetzungsverhältnis zwischen der Verschiebestrecke des Druckknopfes 13 und der Verschiebestrecke des Schiebers 16 eingestellt bzw. vorgegeben werden.The first extension 15 and, if applicable, the second extension 30 are arranged on a slide 16 which is mounted longitudinally displaceably within the switching device housing 6. The slide 16 is preferably connected to the push button 13 by means of a lever arm 17. This enables the first or second armature of the respective relay 7, 20 to be actuated, with a certain degree of freedom in the placement of the push button 13 being given. Through the lever arm 17, a transmission ratio between the displacement distance of the push button 13 and the displacement distance of the slide 16 can be set or specified.

Gemäß der bevorzugten Ausführungsform ist vorgesehen, dass der Hebelarm 17 durch einen ersten Schenkel 18 einer, in dem Schaltgerätegehäuse 6 gelagerten Schenkelfeder 19 gebildet ist. Die betreffende Schenkelfeder 19 ist insbesondere in den Fig. 1 und 2 dargestellt. Durch die Schenkelfeder 19 kann sowohl die Übersetzung der Bewegung des Druckknopfes 13 auf den Schieber 16 gewährleistet werden, als auch ein Rückstellmoment sowohl für den Schieber 16 als auch den Druckknopf 13 erzeugt werden. Der Druckknopf 13 liegt gemäß der bevorzugten Ausführungsform auf dem ersten Schenkel 18 auf. Der Schieber 16 weist einen Haltebereich auf, in welchem der Schieber 16 den ersten Schenkel 18 beidseitig umgreift.According to the preferred embodiment it is provided that the lever arm 17 is formed by a first leg 18 of a leg spring 19 mounted in the switching device housing 6. The leg spring 19 in question is in particular in the Figs. 1 and 2 shown. The torsion spring 19 can both ensure the translation of the movement of the push button 13 onto the slide 16 and also generate a restoring torque for both the slide 16 and the push button 13. According to the preferred embodiment, the push button 13 rests on the first leg 18. The slide 16 has a holding area in which the slide 16 engages around the first leg 18 on both sides.
