Definitions
- the invention relates to an electromagnetic release for a service switching device, in particular for a circuit breaker, with a fixed magnetic core and a movable armature, which are arranged in a cylindrical, tubular bobbin having a central axis, with a wound around the bobbin coil having two end portions and at each end part a fitting, according to the preamble of claim 1.
- the invention also relates to a service switching device, in particular a circuit breaker or residual current circuit breaker, comprising at least one electromagnetic actuator comprising a cylindrical, tubular bobbin having a central axis, a coil wound around the bobbin, the two end portions and a terminal piece at each end portion the preamble of claim 5.
- a service switching device in particular a circuit breaker or residual current circuit breaker, comprising at least one electromagnetic actuator comprising a cylindrical, tubular bobbin having a central axis, a coil wound around the bobbin, the two end portions and a terminal piece at each end portion the preamble of claim 5.
- Circuit breakers have an electromagnetic and a thermal release of which contribute to the elimination of the switching device in the event of an overcurrent and the electromagnetic release on occurrence of a short-circuit current, the thermal release. While the thermal release acts only on a Verklinkungsstelle within a switch lock, which is coupled to a movable contact lever, for their unlatching action, the electromagnetic release opens when a short-circuit current occurs, the contact lever directly by striking; At the same time, the electromagnetic release also actuates the switch lock so that the switching device is permanently open.
- a generic electromagnetic actuator usually has a fixed core to which a movable armature is assigned, the core and the armature being covered by a coil tube, so that the armature is guided optimally with respect to the core.
- a coil is wound, which is traversed by a short circuit current when a short circuit occurs.
- the core is attached as a separate component to a yoke or a core plate, which faces the contact lever, so that the occurrence of a short-circuit current, the core helps to pull the anchor into the interior of the coil.
- the anchor drives out a striker, which can then act on the contact lever opening.
- EP 1 463 082 A1 shows an electromagnetic switching device having a coil and a magnetic yoke comprising magnetic release, wherein the coil is electrically connected to a first, longer coil terminal 9 with a terminal and a second, shorter coil terminal 10 with the magnet yoke.
- the present invention is therefore in the light of the prior art, the object to provide an electromagnetic release, which can be assembled easier and less expensive in an automated assembly process.
- the object of the invention is based on the electromagnetic release solved according to the invention by a generic electromagnetic release with the characterizing features of claim 1.
- the connecting pieces are arranged and constructed mirror-symmetrically with respect to an imaginary mirror plane, the mirror plane extending in the middle between the two end parts perpendicular to the central axis of the coil, and each connecting piece moves away from the windings of the coil in a direction parallel to the central axis. From the mirror-symmetrical structure it follows that twisting the coil when feeding to a production machine no longer has any negative effects. Because even if in accordance with the invention Electromagnetic release the coil is rotated by 180 °, so the fittings of the coil are still in the same position relative to their welding points in the device. The coil can thus be welded to the right or left. This enables an economical automated assembly of an electromagnetic release.
- the invention is located on an end face of the bobbin connected to the magnetic core connecting plate which extends in a direction parallel to the central axis direction of the bobbin away.
- a connecting piece of the coil can be welded to this connecting lug.
- the terminal lug can be made long enough to accommodate the length of the fitting.
- the distance of the connecting tab from the central axis corresponds to the distance of the connecting pieces of the coil from the central axis when the coil is pushed onto the bobbin, so that when the coil is pushed onto the bobbin, the connecting piece comes into contact with the connecting lug and can be welded thereto ,
- the distance between the end face of the bobbin adjacent the core plate and the end portion of the coil adjacent thereto is greater than the distance between the opposite end face of the bobbin and the end portion of the coil adjacent thereto is.
- the coil can be optimally positioned on the coil tube.
- the object is achieved by a generic service switching device with the characterizing features of claim 5. Accordingly, the coil with the fittings mirror-symmetrically based on an imaginary mirror plane in the middle between the two end portions perpendicular to the central axis Coil extends, and each terminal moves away in a direction parallel to the central axis of the windings of the coil.
- a circuit breaker 20 (see Fig. 2 ) has a schematically illustrated switching mechanism 21 with a Verklinkungsstelle (not shown).
- the switching mechanism 21 is coupled to a rotatably mounted contact lever 22.
- the contact lever 22 carries at its free end a movable contact piece 23, which forms a contact point 25 together with a fixed contact piece 24.
- the stationary contact piece 24 is associated with an arc guide plate 26, which leads one of the bases of an arc, which arises when opening the contact point 25, for example, in a quenching chamber 27.
- the movable contact lever 22 is associated with an electromagnetic release 1, which has an armature 13 which is held displaceably in the direction of arrow P in the interior of a cylindrical tube-shaped bobbin.
- an electromagnetic release 1 which has an armature 13 which is held displaceably in the direction of arrow P in the interior of a cylindrical tube-shaped bobbin.
- the armature 13 moves in the direction of arrow P inside the bobbin 2, attracted by the core 30. He meets there, directly or indirectly, on a striker, of which in the untripped position after Fig. 1 and 2 only the extreme tip can be seen.
- the armature 13 drives the striker in the direction of arrow P out of the bobbin 2, so that it meets against the contact lever 22 and this pivots in the opening direction.
- the bobbin 2 has the shape of a cylindrical tube with a central axis 3 between the points X and X '. In the inside is at the in the Fig. 1 attached to the left side of the core, of which a small protruding piece with the reference numeral 30 can be seen.
- the core is attached to a core plate 12, on which the left end of the coil tube 2 is supported. With the core plate 12, a first sheet is connected, which is angled as an arc guide plate 26 to the right and extends parallel to the central axis 3 below the bobbin 2. Next, a tab 11 is connected to the core plate 12, which is angled to the left and runs parallel to the central axis 3 of the left end side of the bobbin away.
- a coil 4 is wound on the bobbin 2.
- Their two connecting pieces 7, 8 are mirror-symmetrically related to an imaginary mirror plane 9 arranged and executed, see section line YY ', which runs in the middle between the two end portions 5, 6 perpendicular to the central axis 3 of the coil 4.
- Each connecting piece 7, 8 moves away in a direction parallel to the central axis 3 from the windings of the coil 4.
- the coil 4 is welded to the tab 11.
- the coil 4 is welded to a guide rail 31, which establishes the connection to the second connection terminal 29. Because of the mirror symmetry of the connecting pieces 8, 9 they are the same length.
- each end portion 6, 5 of the coil 4 to the end of the associated fitting 8, 7 is the same size on each side.
- the connecting pieces 8, 7 extend parallel to the central axis 3 at a distance a from this.
- the distance a is chosen so that the connecting pieces 8, 9 come to rest on the tab 11 when the coil 4 is pushed onto the bobbin 2.
- There is no bending of the connecting piece 8 is required to bring it into the correct position for a weld with the terminal lug 11, the sliding of the coil 4 is sufficient to the bobbin 2. This is important for an economically feasible automatic assembly.
- the left end portion 6 of the coil 4 has a distance d from the core plate 12. This distance results from the length of the connecting piece 8. It is adjustable by varying the length of the connecting lug 11. The shorter the connecting lug 11 is selected, the longer is the distance d. About the distance d, the position of the coil 4 is set on the bobbin 2 and thus the position of the coil 4 relative to the core and the armature inside the bobbin 2. The length of the terminal lug 11, for example, by the available space in the housing be limited. Then the coil 4 comes to lie more right on the bobbin 2, the distance d is greater. Then, the core inside the bobbin 2 would be arranged more to the right, so that the coil 4 comes to rest optimally based on the core and the anchor.

Die Erfindung betrifft außerdem ein Installationsschaltgerät, insbesondere einen Leitungsschutzschalter oder Fehlerstromschutzschalter, mit wenigstens einem elektromagnetischen Auslöser, welcher einen zylindrischen, rohrförmigen Spulenkörper mit einer Mittelachse, eine um den Spulenkörper gewickelte Spule, die zwei Endteile und an jedem Endteil ein Anschlussstück aufweist, umfasst, gemäß dem Oberbegriff des Anspruchs 5.The invention also relates to a service switching device, in particular a circuit breaker or residual current circuit breaker, comprising at least one electromagnetic actuator comprising a cylindrical, tubular bobbin having a central axis, a coil wound around the bobbin, the two end portions and a terminal piece at each end portion the preamble of
Leitungsschutzschalter besitzen einen elektromagnetischen und einen thermischen Auslöser, von denen der thermische Auslöser bei Auftreten eines Überstromes und der elektromagnetische Auslöser bei Auftreten eines Kurzschlussstromes zur Ausschaltung des Schaltgerätes beitragen. Während der thermische Auslöser lediglich auf eine Verklinkungsstelle innerhalb eines Schaltschlosses, das mit einem beweglichen Kontakthebel gekoppelt ist, zu deren Entklinkung einwirkt, öffnet der elektromagnetische Auslöser bei Auftreten eines Kurzschlussstromes den Kontakthebel unmittelbar durch Aufschlagen; gleichzeitig betätigt der elektromagnetische Auslöser auch das Schaltschloss, damit das Schaltgerät bleibend geöffnet ist.Circuit breakers have an electromagnetic and a thermal release of which contribute to the elimination of the switching device in the event of an overcurrent and the electromagnetic release on occurrence of a short-circuit current, the thermal release. While the thermal release acts only on a Verklinkungsstelle within a switch lock, which is coupled to a movable contact lever, for their unlatching action, the electromagnetic release opens when a short-circuit current occurs, the contact lever directly by striking; At the same time, the electromagnetic release also actuates the switch lock so that the switching device is permanently open.
Ein gattungsgemäßer elektromagnetischer Auslöser besitzt üblicherweise einen feststehenden Kern, dem ein beweglicher Anker zugeordnet ist, wobei der Kern und der Anker von einem Spulenrohr umfasst sind, so dass der Anker optimal bezogen auf den Kern geführt ist. Um das Spulenrohr herum ist eine Spule gewickelt, die bei Auftreten eines Kurzschlusses von einem Kurzschlussstrom durchflossen ist. Der Kern ist als eigenständiges Bauteil an einen Joch oder einer Kernplatte angebracht, die dem Kontakthebel zugewandt ist, damit beim Auftreten eines Kurzschlussstromes der Kern mithilft, den Anker ins Innere der Spule hineinzuziehen. Der Anker treibt dabei einen Schlagstift heraus, der dann auf den Kontakthebel öffnend wirken kann. Gattungsgemäße elektromagnetische Auslöser sind bekannt, beispielsweise aus der
Der vorliegenden Erfindung liegt im Lichte des Standes der Technik daher die Aufgabe zugrunde, einen elektromagnetischen Auslöser zu schaffen, der in einem automatisierten Montageprozess einfacher und weniger aufwändig zusammengesetzt werden kann.The present invention is therefore in the light of the prior art, the object to provide an electromagnetic release, which can be assembled easier and less expensive in an automated assembly process.
Die der Erfindung zugrundeliegende Aufgabe wird bezüglich des elektromagnetischen Auslösers erfindungsgemäß gelöst durch einen gattungsgemäßen elektromagnetischen Auslöser mit den kennzeichnenden Merkmalen des Anspruchs 1.The object of the invention is based on the electromagnetic release solved according to the invention by a generic electromagnetic release with the characterizing features of claim 1.
Erfindungsgemäß sind die Anschlussstücke spiegelsymmetrisch bezogen auf eine gedachte Spiegelebene angeordnet und aufgebaut, wobei die Spiegelebene in der Mitte zwischen den beiden Endteilen senkrecht zur Mittelachse der Spule verläuft, und jedes Anschlussstück entfernt sich in einer zur Mittelachse parallelen Richtung von den Wicklungen der Spule. Aus dem spiegelsymmetrischen Aufbau ergibt sich, dass ein Verdrehen der Spule beim Zuführen zu einem Fertigungsautomaten keine negativen Auswirkungen mehr hat. Denn auch wenn bei einem erfindungsgemäßen elektromagnetischen Auslöser die Spule um 180° verdreht ist, so sind die Anschlussstücke der Spule immer noch in der gleichen Lage bezogen auf ihre Anschweißpunkte im Gerät. Die Spule ist somit rechts- oder links herum anschweißbar. Damit wird eine wirtschaftliche automatisierte Montage eines elektromagnetischen Auslösers möglich.According to the invention, the connecting pieces are arranged and constructed mirror-symmetrically with respect to an imaginary mirror plane, the mirror plane extending in the middle between the two end parts perpendicular to the central axis of the coil, and each connecting piece moves away from the windings of the coil in a direction parallel to the central axis. From the mirror-symmetrical structure it follows that twisting the coil when feeding to a production machine no longer has any negative effects. Because even if in accordance with the invention Electromagnetic release the coil is rotated by 180 °, so the fittings of the coil are still in the same position relative to their welding points in the device. The coil can thus be welded to the right or left. This enables an economical automated assembly of an electromagnetic release.
Gemäß einer besonders vorteilhaften Ausführungsform der Erfindung befindet sich an einer Stirnseite des Spulenkörpers eine mit dem Magnetkern verbundene Anschlusslasche, die in einer zur Mittelachse parallelen Richtung von dem Spulenkörper weg verläuft. An dieser Anschlusslasche kann ein Anschlussstück der Spule angeschweißt werden. Die Anschlusslasche kann so lang gemacht werden, dass sie die Länge des Anschlussstückes aufnimmt. Der Abstand der Anschlusslasche von der Mittelachse entspricht dem Abstand der Anschlussstücke der Spule von der Mittelachse wenn die Spule auf dem Spulenkörper aufgeschoben ist, so dass bei einem Aufschieben der Spule auf den Spulenkörper das Anschlussstück an die Anschlusslasche in Anlage kommt und mit dieser verschweißt werden kann.According to a particularly advantageous embodiment of the invention is located on an end face of the bobbin connected to the magnetic core connecting plate which extends in a direction parallel to the central axis direction of the bobbin away. A connecting piece of the coil can be welded to this connecting lug. The terminal lug can be made long enough to accommodate the length of the fitting. The distance of the connecting tab from the central axis corresponds to the distance of the connecting pieces of the coil from the central axis when the coil is pushed onto the bobbin, so that when the coil is pushed onto the bobbin, the connecting piece comes into contact with the connecting lug and can be welded thereto ,
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung liegt eine Stirnseite des zylindrischen Spulenkörpers an einer mit dem Magnetkern verbundenen Kernplatte an, an der die Anschlusslasche angeformt ist.According to a further advantageous embodiment of the invention is an end face of the cylindrical bobbin on a connected to the magnetic core core plate on which the terminal lug is formed.
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung ist der Abstand zwischen der an der Kernplatte anliegenden Stirnseite des Spulenkörpers und dem Endteil der Spule, das dieser benachbart ist, größer ist als der Abstand zwischen der gegenüberliegenden Stirnseite des Spulenkörpers und dem Endteil der Spule, das dieser benachbart ist. Damit kann die Spule optimal auf dem Spulenrohr positioniert werden.According to a further advantageous embodiment of the invention, the distance between the end face of the bobbin adjacent the core plate and the end portion of the coil adjacent thereto is greater than the distance between the opposite end face of the bobbin and the end portion of the coil adjacent thereto is. Thus, the coil can be optimally positioned on the coil tube.
Die der Erfindung zugrundeliegende Aufgabe wird bezüglich des Installationsschaltgerätes erfindungsgemäß gelöst durch ein gattungsgemäßes Installationsschaltgerät mit den kennzeichnenden Merkmalen des Anspruchs 5. Demgemäß ist erfindungsgemäß die Spule mit den Anschlussstücken spiegelsymmetrisch bezogen auf eine gedachte Spiegelebene, die in der Mitte zwischen den beiden Endteilen senkrecht zur Mittelachse der Spule verläuft, und jedes Anschlussstück entfernt sich in einer zur Mittelachse parallelen Richtung von den Wicklungen der Spule.With respect to the installation switching device according to the invention, the object is achieved by a generic service switching device with the characterizing features of

Dem beweglichen Kontakthebel 22 ist ein elektromagnetischer Auslöser 1 zugeordnet, der einen Anker 13 aufweist, welcher im Inneren eines zylinderrohrförmigen Spulenkörpers 2 in Pfeilrichtung P verschieblich gehalten ist. Bei Anliegen eines Kurzschlussstromes bewegt sich der Anker 13 in Pfeilrichtung P Innere des Spulenkörpers 2 hinein, angezogen von dem Kern 30. Er trifft dort, direkt oder indirekt, auf einen Schlagstift, von dem in der nicht ausgelösten Stellung nach
Der Aufbau des elektromagnetischen Auslösers 1 soll nun näher betrachtet werden, siehe
Auf den Spulenkörper 2 ist eine Spule 4 aufgewickelt. Ihre beiden Anschlussstücke 7, 8 sind spiegelsymmetrisch bezogen auf eine gedachte Spiegelebene 9 angeordnet und ausgeführt, siehe Schnittlinie YY', die in der Mitte zwischen den beiden Endteilen 5, 6 senkrecht zur Mittelachse 3 der Spule 4 verläuft. Jedes Anschlussstück 7, 8 entfernt sich in einer zur Mittelachse 3 parallelen Richtung von den Wicklungen der Spule 4. An dem linken Anschlussstück 8 ist die Spule 4 mit der Lasche 11 verschweißt. An dem rechten Anschlussstück 7 ist die Spule 4 mit einer Leitschiene 31 verschweißt, die die Verbindung zu der zweiten Anschlussklemme 29 herstellt. Wegen der Spiegelsymmetrie der Anschlussstücke 8, 9 sind diese gleich lang. Der Abstand von jedem Endteil 6, 5 der Spule 4 zu dem Ende des zugehörigen Anschlussstücks 8, 7 ist auf jeder Seite gleich groß. Die Anschlussstücke 8, 7 verlaufen parallel zu der Mittelachse 3 in einem Abstand a von dieser. Der Abstand a ist so gewählt, dass die Anschlussstücke 8, 9 an der Lasche 11 zum Anliegen kommen, wenn die Spule 4 auf den Spulenkörper 2 aufgeschoben ist. Es ist kein Zurechtbiegen des Anschlussstückes 8 erforderlich, um es in die für eine Verschweißung mit der Anschlusslasche 11 richtige Lage zu bringen, das Aufschieben der Spule 4 auf den Spulenkörper 2 genügt. Dies ist wichtig für eine wirtschaftlich durchzuführende automatische Montage. Auch wenn die Spule 4 um 180° bezüglich der Ebene 9 verdreht auf den Spulenkörper 2 aufgeschoben wird, passt das dann links liegende Anschlussstück 7 genau zu der Anschlusslasche 11, denn beide Anschlussstücke sind wegen der Spiegelsymmetrie gleich lang und haben den gleichen Abstand von der Mittelachse 3.On the
Das linke Endteil 6 der Spule 4 hat von der Kernplatte 12 eine Abstand d. Dieser Abstand resultiert aus der Länge des Anschlussstückes 8. Er ist einstellbar durch Variation der Länge der Anschlusslasche 11. Je kürzer die Anschlüsslasche 11 gewählt wird, desto länger ist der Abstand d. Über den Abstand d wird die Lage der Spule 4 auf dem Spulenkörper 2 festgelegt und damit die Lage der Spule 4 bezogen auf den Kern und den Anker im Inneren des Spulenkörpers 2. Die Länge der Anschlusslasche 11 kann beispielsweise durch den zur Verfügung stehenden Bauraum im Gehäuse begrenzt sein. Dann kommt die Spule 4 mehr nach rechts auf dem Spulenkörper 2 zu liegen, der Abstand d wird größer. Dann würde auch der Kern im Inneren des Spulenkörpers 2 mehr nach rechts angeordnet, damit die Spule 4 optimal bezogen auf den Kern und den Anker zu liegen kommt.The
