Description

Die Erfindung bezieht sich auf ein elektromagnetisches Schaltgerät, insbesondere ein Schütz, mit einer in ein Schaltgerätgehäuse einführbaren Einschubeinheit, die einen Spulenkörper für eine Spule umfasst, wie sie beispielsweise aus der WO 95/12891 bekannt ist.The invention relates to an electromagnetic switching device, in particular a contactor, with an insertable into a switching device housing plug-in unit comprising a bobbin for a coil, as for example from the WO 95/12891 is known.

Eine solche auch als Spulenbaugruppe bezeichnete Einschubeinheit besteht zumindest aus einem Spulenkörper, der eine oder mehrere Kupfer-Wicklungen trägt und einen Anschlussbereich, über den die Wicklung mit einer externen Spannung versorgt wird. Die Spulenbaugruppe bildet den Antrieb des elektromagnetischen Schaltgeräts.Such a plug-in unit, also referred to as a coil module, consists at least of a coil body which carries one or more copper windings and a connection region via which the winding is supplied with an external voltage. The coil assembly forms the drive of the electromagnetic switching device.

Eine spezielle Ausführung eines solchen Antriebs ist beispielsweise der sogenannte Sparschaltungsantrieb. Hierbei wird eine relativ hohe Einschalt- bzw. Anzugsenergie, die zum Schalten des Schaltgeräts erforderlich ist, zu einem vorgegebenen Zeitpunkt auf eine deutlich niedrigere Halteenergie zurückgeschaltet. Dies hat den Vorteil, dass die Energieaufnahme des Schaltgerätes im eingeschalteten Zustand verringert und dementsprechend auch die Verlustleistung und damit verbunden die Wärmeabstrahlung reduziert ist.A special embodiment of such a drive, for example, the so-called economy circuit drive. In this case, a relatively high turn-on or pull-in energy, which is required for switching the switching device, switched back to a significantly lower holding energy at a given time. This has the advantage that the energy consumption of the switching device is reduced in the on state and, accordingly, the power loss and associated heat dissipation is reduced.

Zur Realisierung einer solchen Sparschaltung ist es bekannt, eine Spule mit zwei Wicklungen zu versehen, von denen eine die Anzugswicklung und die andere die Haltewicklung bildet. Mittels eines mechanischen Schaltelementes wird nun diese Anzugswicklung unterbrochen, so dass nur noch die Haltewicklung stromdurchflossen ist. Die Betätigung des mechanischen Schaltelementes erfolgt dabei über ein geeignetes Auslöseelement, das durch die bewegte Einheit des Schaltgerätes bewegt wird und zu einem vorgegebenen Zeitpunkt während des Einschaltvorganges das Schaltelemente betätigt. Der von der bewegten Einheit (Anker und Kontaktschieber) zwischen dem Abschaltzeitpunkt der Anzugswicklung und ihrer Endposition (Haltestellung) zurückzulegende Differenzweg wird durch die kinetische Energie der bewegten Einheit des Schaltgerätes überwunden.To realize such a savings circuit, it is known to provide a coil with two windings, one of which forms the attraction winding and the other the holding winding. By means of a mechanical switching element, this attracting winding is now interrupted, so that only the holding winding is current-flowing. The actuation of the mechanical switching element takes place via a suitable triggering element, which is moved by the moving unit of the switching device and at a predetermined time during the switch-on actuates the switching elements. The one of the moving Unit (armature and contact slide) between the turn-off time of the attraction winding and its end position (holding position) to be traversed differential path is overcome by the kinetic energy of the moving unit of the switching device.

Bei einer aus der US 5,040,089 bekannten Sparschaltung eines Gleichstrom-Relais wird der Gesamtenergieverbrauch reduziert, indem durch Zuschalten eines Wicklungsteils der Antriebsspule oder eines zusätzlichen Widerstandes der über die Auslösespule geführte Auslösestrom von einem vergleichsweise hohen Einschaltstromwert auf einen vergleichsweise niedrigen Haltestromwert reduziert wird.At one of the US 5,040,089 known savings circuit of a DC relay, the total energy consumption is reduced by by connecting a winding part of the drive coil or an additional resistor of the tripping coil guided tripping current is reduced from a comparatively high inrush current value to a comparatively low holding current value.

Um sicherzustellen, dass die Haltestellung mit möglichst geringer Anzugsenergie erreicht werden kann, ist anzustreben, den Schaltpunkt so weit wie möglich vor die Haltestellung zu legen. Dies erfordert eine genaue Lage des Schaltpunktes, um ein Erreichen der Haltestellung sicherzustellen.In order to ensure that the holding position can be achieved with the least possible tightening energy, it is desirable to place the switching point as far as possible in front of the holding position. This requires a precise location of the switching point to ensure that the holding position has been reached.

Der Erfindung liegt nun die Aufgabe zugrunde, ein elektromagnetisches Schaltgerät anzugeben, das durch seinen konstruktiven Aufbau eine möglichst geringe Toleranzbreite für den Schaltpunkt eines im Schaltgerätgehäuse für die Realisierung einer mechanischen Sparschaltung eingebauten elektrischen Schalters ermöglicht.The invention is an object of the invention to provide an electromagnetic switching device, which allows by its structural design the smallest possible tolerance width for the switching point of a built-in switching device housing for the realization of a mechanical economy circuit electrical switch.

Die genannte Aufgabe wird gemäß der Erfindung gelöst mit den Merkmalen des Patentanspruches 1. Das erfindungsgemäße elektromagnetische Schaltgerät, insbesondere ein Schütz, enthält ein Schaltgerätgehäuse und eine in dieses einführbare Einschubeinheit, die einen Spulenkörper für eine Spule sowie ein an einem Gehäuseteil der Einschubeinheit gelagertes Auslöseelement zum mechanischen Betätigen des Schaltelementes eines elektrischen Schalters für eine Sparschaltung umfasst, der auf einer in der Einschubeinheit angeordneten und von dem Gehäuseteil separaten Tragstruktur montiert ist und mit einer Stützkontur an einer Lagerkontur des Gehäuseteils anliegt.The above object is achieved according to the invention with the features of claim 1. The electromagnetic switching device according to the invention, in particular a contactor, contains a switching device housing and an insertable into this insertion unit, which has a bobbin for a coil and a mounted on a housing part of the plug-in release element for mechanical actuation of the switching element of an electrical switch for a savings circuit comprising arranged on a in the plug-in unit and of the housing part is mounted separate support structure and rests with a support contour on a bearing contour of the housing part.

Durch diese Maßnahmen ist der zur Realisierung der Sparschaltung vorgesehene Schalter in einer festen Lage zu einer Referenzfläche in demselben Gehäuseteil positioniert, in dem auch das Auslöseelement gelagert ist, obwohl es sich bei dem Gehäuseteil und der Tragstruktur um zwei separate Bauteile handelt, die erst bei der Fertigung der Einschubeinheit zusammengefügt werden. Die Lage des Schalters relativ zum Auslöseelement ist durch diese Maßnahmen unabhängig von den Toleranzen, mit denen er auf der Tragstruktur, vorzugsweise eine Leiterplatte, vormontiert ist oder mit der diese in der Einschubeinheit relativ zum Gehäuseteil angeordnet ist. Dadurch sind die Schaltwegtoleranzen auf ein Minimum verringert.As a result of these measures, the switch provided for realizing the economy circuit is positioned in a fixed position relative to a reference surface in the same housing part in which the triggering element is also mounted, although the housing part and the support structure are two separate components which are only used during the Manufacture of the plug-in unit are joined together. The position of the switch relative to the trigger element is independent of the tolerances with which it is on the support structure, preferably a printed circuit board, pre-assembled by these measures or with which it is arranged in the withdrawable unit relative to the housing part. As a result, the Schaltwegtoleranzen are reduced to a minimum.

In einer bevorzugten Ausgestaltung der Erfindung wird die beim Betätigen des Schaltelementes auf den Schalter ausgeübte Kraft über die Stützkontur auf die Lagerkontur geleitet. Durch diese Maßnahme ist sichergestellt, dass der Schalter auch beim Betätigen in einer festen Bezugsposition Gehäuseteil und damit zum Auslöseelement verbleibt.In a preferred embodiment of the invention, the force exerted on the switch during actuation of the switching element is conducted via the support contour onto the bearing contour. By this measure, it is ensured that the switch remains when pressed in a fixed reference position housing part and thus to the triggering element.

Insbesondere ist der elektrische Schalter auf einer im Wesentlichen parallel zur Außenwand des Gehäuseteiles angeordneten Leiterplatte montiert und ragt durch diese mit zumindest einem die Stützkontur bildenden Teil seines Gehäuses hindurch. Dies ermöglicht einen fertigungstechnisch besonders einfachen Aufbau der Einschubeinheit.In particular, the electrical switch is mounted on a substantially parallel to the outer wall of the housing part arranged printed circuit board and projects through this with at least one support contour forming part of its housing. This allows a manufacturing technology particularly simple construction of the plug-in unit.

Vorzugsweise ist die Lagerkontur an der Innenseite der Außenwand angeordnet, die insbesondere in diesem Bereich eine Versteifungsstruktur aufweist. Dadurch werden Verformungen des Gehäuseteils beim Betätigen des Schaltelementes weitgehend vermieden.Preferably, the bearing contour is arranged on the inside of the outer wall, which has a stiffening structure, in particular in this area. As a result, deformations of the housing part during actuation of the switching element are largely avoided.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist am Gehäuseteil eine Wanne angeformt, an der der Schalter angeordnet und mittels einer Vergussmasse lagefixiert ist. Dies ist fertigungstechnisch besonders einfach zu realisieren. Außerdem dient die Vergussmasse zugleich zum Schutz der zusätzlich zum Schalter auf der Leiterplatte angeordneten elektrischen Bauelemente.In a further advantageous embodiment of the invention, a trough is formed on the housing part, on which the switch is arranged and fixed in position by means of a potting compound. This is manufacturing technology particularly easy to implement. In addition, the potting compound at the same time serves to protect the electrical components arranged in addition to the switch on the printed circuit board.

Vorzugsweise sind am Gehäuseteil zwei seitliche Lagerarme zur Lagerung des Auslöseelements angeordnet. Dadurch ist eine stabile und positionsgenaue Lagerung des Auslöseelements ermöglicht.Preferably, two lateral bearing arms for supporting the trigger element are arranged on the housing part. This allows a stable and positionally accurate storage of the trigger element.

In einer weiteren bevorzugten Ausgestaltung der Erfindung ist der Spulenkörper an einer seiner Stirnseiten mit zumindest einem Verbindungsarm versehen, mit dem er am Gehäuseteil gelagert ist, wobei insbesondere die andere Stirnseite zumindest einen Rasthaken aufweist, der in eine korrespondierende Ausnehmung am Gehäuseteil verrastet. Dadurch wird eine stabile Lagerung des Spulenkörpers am Gehäuseteil sichergestellt.In a further preferred embodiment of the invention, the bobbin is provided on one of its end faces with at least one connecting arm, with which it is mounted on the housing part, wherein in particular the other end face has at least one latching hook which locks in a corresponding recess on the housing part. This ensures a stable mounting of the bobbin on the housing part.

Insbesondere ist die Ausnehmung im Lagerarm für das Auslöseelement angeordnet. Dies ermöglicht eine besonders einfache konstruktive Ausgestaltung, da die Lagerarme sowohl die Funktion der Lagerung des Auslöseelementes als auch die Funktion der Fixierung des Spulenkörpers übernehmen.In particular, the recess is arranged in the bearing arm for the triggering element. This allows a particularly simple structural design, since the bearing arms take over both the function of the storage of the trigger element and the function of fixing the bobbin.

Das Gehäuseteil 40 ist mit Seitenwänden 46 versehen, die sich in das Innere der Einschubeinheit erstrecken und gemeinsam mit der Deckelseite eine Wanne 48 zur Aufnahme der Leiterplatte 22 (FIG 2) bilden. Am Boden der Wanne 48 ist ein Stützzylinder 50 angeformt. In den Außenmantel des Stützzylinders 50 münden am Boden angeformte Querstreben 52, die zugleich eine Versteifungsstruktur für das aus einem Kunststoffspritzgussteil bestehende Gehäuseteil 40 im Bereich des Stützzylinders 50 bilden. Die aus dem Stützzylinder 50 und den Querstreben 52 gebildete Versteifungsstruktur befindet sich in einer Vertiefung des Bodens der Wanne 48.The housing part 40 is provided with side walls 46 which extend into the interior of the plug-in unit and together with the cover side form a trough 48 for receiving the printed circuit board 22 (FIG. 2). At the bottom of the tub 48, a support cylinder 50 is formed. In the outer jacket of the support cylinder 50 open at the bottom formed transverse struts 52, which also form a stiffening structure for the existing of a plastic injection molded housing part 40 in the region of the support cylinder 50. The stiffening structure formed from the support cylinder 50 and the transverse struts 52 is located in a depression of the bottom of the tub 48.

FIG 4 zeigt die Einschubeinheit 4 bei in das Gehäuseteil 40 eingeschobenem Spulenkörper 12. In dieser FIG ist zu erkennen, dass die bestückte Leiterplatte 22 in der Wanne 48 gelagert ist. Der Schalter 24 befindet sich dabei über der in der FIG nicht mehr sichtbaren Versteifungsstruktur, wobei der Stützzylinder 50 (FIG 3) mit der Längsachse des Schaltelementes 30, d. h. mit der Richtung der auf dieses beim Betätigen ausgeübten Kraft fluchtet.4 shows the plug-in unit 4 with the coil body 12 inserted into the housing part 40. It can be seen in this FIG. That the populated printed circuit board 22 is mounted in the tub 48. The switch 24 is located above the stiffening structure, which is no longer visible in the FIG, wherein the Supporting cylinder 50 (FIG 3) with the longitudinal axis of the switching element 30, that is aligned with the direction of the force exerted on this during actuation force.

FIG 5 zeigt nun die Einbaueinheit 4 mit montiertem Auslöseelement 60. Das Auslöseelement 60 ist mit einer Welle 62 schwenkbar in Lageraugen 64 der Lagerarme 14 gelagert. Auf der Welle 62 ist ein Auslösehebel 66 fixiert, der bei einer durch den in der FIG nicht dargestellten Anker des Schaltgerätes herbeigeführten Schwenkbewegung der Welle 62 das Schaltelement 30 des Schalters 24 betätigt.5 now shows the mounting unit 4 with mounted trigger element 60. The trigger element 60 is pivotally mounted with a shaft 62 in bearing lugs 64 of the bearing arms 14. On the shaft 62, a trigger lever 66 is fixed, which actuates the switching element 30 of the switch 24 at a caused by the armature of the switching device, not shown in the figure, pivotal movement of the shaft 62.

Gemäß FIG 6 weist der Schalter 24 einen Lagerzapfen 68 auf, mit dem er durch die Leiterplatte 22 hindurchgeführt ist. Der Lagerzapfen 68 ist im Wesentlichen hohlzylindrisch und weist einen Längsschlitz auf, der diesen Hohlzylinder in zwei Halbschalen trennt. Dadurch wird eine Einführung des Lagerzapfens 68 in eine entsprechende Bohrung der Leiterplatte 22 erleichtert. Durch eine Verjüngung am Umfang des Lagerzapfens 68 wird der Schalter 24 auf der Leiterplatte 22 verrastet, so dass dessen Montage erleichtert ist.According to FIG. 6, the switch 24 has a bearing journal 68 with which it is passed through the printed circuit board 22. The journal 68 is substantially hollow cylindrical and has a longitudinal slot which separates this hollow cylinder in two half-shells. As a result, an introduction of the bearing journal 68 in a corresponding bore of the printed circuit board 22 is facilitated. By a taper on the circumference of the bearing pin 68 of the switch 24 is locked on the circuit board 22, so that its assembly is facilitated.

Die Stirnfläche des Lagerzapfens 68 bildet eine Stützkontur 70, die sich auf der eine Anlagekontur 72 bildenden Stirnfläche des Stützzylinders 50, von dem in der FIG nur der stirnseitige Rand zu sehen ist, abstützt. Die Leiterplatte 22 wird mit dem vormontierten Schalter 24 und parallel zur Außenwand 73 des Gehäuseteils 40 in die Wanne 48 eingeführt, bis die Stützkontur 70 des Schalters 24 auf der Lagerkontur 72 des Gehäuseteils 40 anliegt. Der Schalter 24 ist dann unabhängig von eventuellen Lagetoleranzen auf der Leiterplatte 22 in seiner Position relativ zum Gehäuseteil 40 festgelegt. In dieser Position wird die Wanne 48 mit einer Vergussmasse 74 aufgefüllt, so dass der Schalter 24 in der Sollposition relativ zum Gehäuseteil 40 fixiert ist. Die Vergussmasse 74 dient zugleich zum Schutz der auf der Leiterplatte zur Realisierung der Sparschaltung angeordneten weiteren elektronischen Bauelemente 25.The end face of the bearing journal 68 forms a support contour 70, which is supported on the end face of the support cylinder 50 forming an abutment contour 72, of which only the frontal edge can be seen in the FIG. The printed circuit board 22 is inserted with the pre-assembled switch 24 and parallel to the outer wall 73 of the housing part 40 in the trough 48 until the support contour 70 of the switch 24 rests on the bearing contour 72 of the housing part 40. The switch 24 is then fixed independently of any position tolerances on the circuit board 22 in its position relative to the housing part 40. In this position, the trough 48 is filled with a potting compound 74, so that the switch 24 is fixed in the desired position relative to the housing part 40. The potting compound 74 also serves to protect the on the circuit board for the realization of the economy circuit arranged further electronic components 25th

Der Schalter 24 wird durch diese Maßnahme bei der Montage in eine feste und vorgegebene räumliche Position zum Gehäuseteil 40 und damit auch zum unmittelbar am Gehäuseteil 40 schwenkbar angeordneten Auslöseelement 66 gebracht, obwohl er auf einer vom Gehäuseteil 40 separaten Tragstruktur, im Ausführungsbeispiel die Leiterplatte 22, vormontiert ist. Mit anderen Worten: Die Toleranzen, mit denen der Schalter auf der Tragstruktur angeordnet ist und mit denen diese in das Gehäuseteil 40 eingebaut ist, haben praktisch keinen Einfluss auf die Schaltwegtoleranzen. Diese sind somit auf ein Minimum reduziert und unabhängig von der Einbaulage des Schalters 24 auf der Leiterplatte 22 sowie der Einbaulage der Leiterplatte 22 in der Wanne 48.The switch 24 is brought by this measure during assembly in a fixed and predetermined spatial position to the housing part 40 and thus also directly to the housing part 40 pivotally mounted release element 66, although he on a separate housing part 40 support structure, in the embodiment, the circuit board 22, is pre-assembled. In other words, the tolerances with which the switch is arranged on the support structure and with which it is installed in the housing part 40, have virtually no influence on the Schaltwegtoleranzen. These are thus reduced to a minimum and regardless of the installation position of the switch 24 on the circuit board 22 and the installation position of the circuit board 22 in the trough 48th

Die auf das Schaltelement 30 vom Auslösehebel 66 ausgeübte Kraft F wirkt dabei senkrecht zur Stützkontur 70 und wird über diese dazu parallelen Anlagekontur 72 eingeleitet, so dass der Schalter 24 auch beim Betätigen in einer stabilen Position relativ zum Gehäuseteil 40 und damit zum Auslöseelement 60 verbleibt.The force F exerted on the switching element 30 by the triggering lever 66 acts perpendicular to the supporting contour 70 and is introduced via this parallel contact contour 72, so that the switch 24 remains in a stable position relative to the housing part 40 and thus to the triggering element 60 even when actuated.

In der alternativen Ausgestaltung der Erfindung gemäß FIG. 7 sind die Verbindungsarme 14 des Spulenkörpers 12 am Gehäuseteil 40 in Führungen 80 eingeschoben, die den Lagerarmen 42 zur schwenkbaren Lagerung des Auslöseelementes 60 gegenüberliegen. An der den Verbindungsarmen 14 gegenüberliegenden Stirnseite 82 des Spulenkörpers 12 ist in den dem Gehäuseteil 40 zugewandten Eckbereichen jeweils ein Rasthaken 84 angeordnet, der in eine Ausnehmung 86 am freien Ende des Lagerarmes 42 eingreift und eine Rastverbindung herstellt. Durch diese konstruktive Ausgestaltung wird eine stabile Lagerung des Spulenkörpers 12 bewirkt, die insbesondere bei großen Bauformen von Vorteil ist.In the alternative embodiment of the invention according to FIG. 7, the connecting arms 14 of the bobbin 12 are inserted on the housing part 40 in guides 80, which are opposite to the bearing arms 42 for the pivotable mounting of the triggering element 60. At the connecting arms 14 opposite end face 82 of the bobbin 12 is in the housing part 40 facing corner regions each have a latching hook 84 which engages in a recess 86 at the free end of the bearing arm 42 and establishes a latching connection. By this structural design, a stable storage of the bobbin 12 is effected, which is particularly advantageous in large designs.
