Abstract

In the device of the invention with a four-legged coil (1), two specially shaped sockets (4 or 5) in the housing (6) are allocated to each of the two winding ends (2, 3). The electrical connection to the four-legged coil (1) is made via terminals (A1, A2) specially shaped to fit the sockets (4, 5). This construction prevents accidental short-circuiting.

Description

Die Erfindung bezieht sich auf ein Schaltgerät, mit einer Vierbeinspule.The invention relates to a switching device with a four-legged coil.

Ein solches Gerät ist z.B. in der DE-OS 30 17 561 offenbart. Hier handelt es sich um ein elektromagnetisches Schaltgerät, z.B. ein Schütz mit benachbarten Anschlußebenen und mit einem Spulenkörper, der in der hinteren Anschlußebene liegende Ansätze zur Herstellung eines Diagonalanschlusses aufweist. Der Spulenkörper ist mit zwei in Richtung der benachbarten Anschlußebenen weisenden Vorsprüngen zur Aufnahme von einsteckbaren Anschlußklemmen versehen. Deren Anschlußschrauben liegen in der der hinteren Anschlußebene benachbarten Anschlußebene. Durch diese Ausführung sind bei dem Schaltgerät die Spulenanschlußmöglichkeiten auf einfache Weise, im Hinblick auf Zahl der Anschlußebenen, optimiert. Damit ist es möglich, bei nicht ausreichenden Platzverhältnissen im Bereich der hinteren Anschlußebene anstelle der hier liegenden Diagonalanschlüsse die im Bereich der benachbarten vorderen Ebene liegenden zwei zusätzlichen Anschlußmöglichkeiten zur Herstellung eines Vertikalanschlusses für die Spulen zu verwenden. Der hier eingesetzte Spulenkörper ermöglicht eine einfache Umrüstung des Schaltgeräts, in dem lediglich in diesen Anschlußklemmen eingesteckt bzw. herausgenommen werden, ohne daß ein neuer Spulenkörper erforderlich ist. Bei der hier beschriebenen Vierbeinspule ist zur Verhinderung von Kurzschlüssen beim Anschluß an eine Spannungsversorgung darauf zu achten, daß die Anschlüsse nicht versehentlich verwechselt werden.Such a device is e.g. disclosed in DE-OS 30 17 561. This is an electromagnetic switching device, e.g. a contactor with adjacent connection levels and with a coil body, which has approaches in the rear connection level for producing a diagonal connection. The coil body is provided with two projections pointing in the direction of the adjacent connection planes for receiving plug-in connection terminals. Their connection screws are in the connection level adjacent to the rear connection level. This design optimizes the coil connection options in the switching device in a simple manner with regard to the number of connection levels. This makes it possible, if there is insufficient space in the area of the rear connection level, instead of the diagonal connections located here, to use the two additional connection options located in the area of the adjacent front level for producing a vertical connection for the coils. The coil former used here enables the switching device to be easily converted by simply plugging in and out of these connecting terminals without the need for a new coil former. In the case of the four-legged coil described here, in order to prevent short circuits when connecting to a power supply, care must be taken that the connections are not accidentally mixed up.

Die Erfindung zielt daher darauf ab, ein Gerät der obengenannten Art zu schaffen, bei dem der zum Kurzschluß führende fehlerhafte Anschluß vermieden wird. Dies wird bei dem obengenannten Gerät dadurch erreicht, daß dem ersten Wicklungsende der Vierbeinspule erste Steckplätze und ihrem zweiten Wicklungsende zweite Steckplätze zum elektrischen Anschluß an eine Versorgungsspannung zugeordnet sind, wobei die ersten Steckplätze verschieden von den zweiten Steckplätzen gestaltet sind, und das erste Wicklungsende durch Einschub einer ersten Anschlußklemme in einen der ersten Steckplätze und das zweite Wicklungsende durch Einschub einer zweiten Anschlußklemme in einen der zweiten Steckplätze kontaktiert ist. Weiterhin weist die erste Anschlußklemme eine dem ersten Steckplatz angepaßte Formkodierung und die zweite Anschlußklemme eine dem zweiten Steckplatz angepaßte Formkodierung auf. Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Ansprüchen 2 bis 4 zu entnehmen.The invention therefore aims to provide a device of the type mentioned above, in which the faulty connection leading to a short circuit is avoided. This will be the case with the The above device is achieved in that the first winding end of the four-legged coil is assigned first slots and its second winding end has second slots for electrical connection to a supply voltage, the first slots being designed differently from the second slots, and the first winding end by inserting a first terminal in one of the first slots and the second winding end is contacted by inserting a second terminal into one of the second slots. Furthermore, the first connection terminal has a shape coding adapted to the first slot and the second connection terminal has a shape coding adapted to the second slot. Further advantageous embodiments of the invention can be found in claims 2 to 4.

Die Geräte nach beanspruchter Bauart bieten individuelle Anschlußmöglichkeit beim Kunden. Die beliebige Umsteckbarkeit der Anschlüsse ermöglicht einen freiwählbaren Anschluß, z.B. von Leistungsschaltern oder Überlastrelais an ein Schaltgerät unter Berücksichtigung der speziellen räumlichen Verhältnisse. Freie Steckplätze an einer Seite des Geräts sind z.B. zum Anschluß eines Beschaltungsbausteins nutzbar. Durch die Formkodierung der Anschlußklemmen wird eine sonst mögliche Verwechslung sicher ausgeschlossen.The devices of the claimed design offer individual connection options at the customer. The arbitrary reversibility of the connections enables a freely selectable connection, e.g. from circuit breakers or overload relays to a switching device taking into account the special spatial conditions. Free slots on one side of the device are e.g. can be used to connect a circuit block. The form coding of the connection terminals reliably prevents any other possible confusion.

Eine Ausführungsform der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Es zeigen:

FIG 1
ein Gerät mit einer Vierbeinspule und steckbaren Anschlußklemmen im Schnitt,
FIG 2,3
ein Gerät mit Vierbeinspule und einseitig gesteckten Anschlußklemmen,
FIG 4
ein Gerät mit einseitig gesteckten Anschlußklemmen und einem zusätzlich angeschlossenen Beschaltungsbaustein,
FIG 5,6
formkodierte Anschlußklemmen.
An embodiment of the invention is explained below with reference to a drawing. Show it:
FIG. 1
a device with a four-legged coil and pluggable connection terminals on average,
FIG 2.3
a device with a four-legged coil and one-sided connection terminals,
FIG 4
a device with connection terminals plugged in on one side and an additional connected circuit module,
FIG 5.6
shape-coded terminals.

In FIG 1 ist in einer Schnittdarstellung andeutungsweise ein Gehäuse 6 eines Gerätes, z.B. eines Schaltgerätes, mit einer Vierbeinspule 1 dargestellt, die ein erstes Wicklungsende 2 und ein zweites Wicklungsende 3 aufweist. Vom ersten Wicklungsende 2 gibt es elektrische Zuleitungen zu zwei ersten Steckplätzen 4 und vom zweiten Wicklungsende 3 sind elektrische Zuleitungen zu zwei zweiten Steckplätzen 5 vorhanden, die jeweils an der Außenwand des Gehäuses 6 vorgesehen sind. Die Steckplätze 4 und 5 sind zu ihrer Unterscheidung verschieden gestaltet. Der Anschluß des Geräts erfolgt über zwei spezielle Anschlußklemmen A1 und A2 mit einer bestimmten an die Steckplätze 4, 5 angepaßten Formkodierung, so daß der Anschluß A1 nur in einen der Steckplätze 4 und der Anschluß A2 nur in einen der Steckplätze 5 steckbar ist. Damit ergibt sich neben der in FIG 1 dargestellten Anordnung der diagonal gegenüberliegenden Anschlüsse A1 und A2 die Möglichkeit, die Anschlüsse, wie in FIG 2,3 gezeigt, nur einseitig, z.B. an der Unterseite oder an der Oberseite des Geräts, einzustecken. Somit kann, wie in FIG 2,3 angedeutet, die jeweils gegenüberliegende freie Seite bei einer Modulbauweise dazu genutzt werden, z.B. einen Leistungsschalter oder ein Uberlastrelais anzuordnen.1 shows a sectional view of a housing 6 of a device, e.g. of a switching device, shown with a four-leg coil 1, which has a first winding end 2 and a second winding end 3. From the first winding end 2 there are electrical leads to two first slots 4 and from the second winding end 3 there are electrical leads to two second slots 5, each of which is provided on the outer wall of the housing 6. Slots 4 and 5 are designed differently to differentiate them. The device is connected via two special connection terminals A1 and A2 with a specific shape coding adapted to the slots 4, 5, so that the connector A1 can only be plugged into one of the slots 4 and the connector A2 only into one of the slots 5. Thus, in addition to the arrangement of the diagonally opposite connections A1 and A2 shown in FIG. 1, there is the possibility of the connections, as shown in FIG. at the bottom or at the top of the device. Thus, as indicated in FIG. 2, 3, the respective opposite free side can be used in a modular construction, e.g. to arrange a circuit breaker or an overload relay.

Gemäß FIG 4 bietet die Erfindung außerdem die Möglichkeit, die noch freien Steckplätze 4, 5 auf einer Seite des Geräts zum Anschluß, z.B. eines Beschaltungsbausteins 7, zu nutzen.According to FIG 4, the invention also offers the possibility of connecting the still free slots 4, 5 on one side of the device, e.g. a circuit block 7 to use.

In FIG 5,6 ist eine mögliche Gestaltungsform der formkodierten Anschlüsse A1 und A2 gezeigt. Die quaderförmigen Anschlußklemmen A1 und A2 unterscheiden sich lediglich dadurch, daß bei der einen die Seite rechtsseitig vom leitenden Mittelstück durch einen Steg verlängert ist (FIG 5), während es bei der anderen Anschlußklemme die gegenüber dem leitenden Mittelstück in der Ansicht links liegende Seite (FIG 6) ist.A possible design of the form-coded connections A1 and A2 is shown in FIG. 5,6. The parallelepiped-shaped terminals A1 and A2 differ only in that one side extends the right-hand side of the conductive centerpiece by a web (FIG. 5), while the other terminal has the side on the left opposite the conductive centerpiece (FIG 6) is.
