Abstract

The invention relates to a tripping slide device for a thermal overload relay. One of a number of thermostatic bimetals engages with the tripping slide device, said number corresponding to the number of phases to be monitored. The slide device is displaced when at least one of the thermostatic bimetals bends and, by mean of this displacement, a breaker mechanism is tripped, which in turn opens a contact. Said slide device comprises two elongated, rectangular-shaped slide elements, which are coupled to the thermocouples. Each slide element comprises a number of slide plates (11, 12, 13, 11a, 12a, 13a), said number corresponding to the number of phases. The adjoining surfaces, situated against the bimetals (31, 32, 33), are each housed in a different recess.

Beschreibungdescription
Die Erfindung betrifft eine Auslöseschieberanordnung nach dem Oberbegriff des An¬ spruches 1.The invention relates to a trigger slide arrangement according to the preamble of the on ¬ award. 1
Eine solche Schieberanordnung für ein thermisches Uberstromrelais hat die Aufgabe, die Bewegung der ThermobimetaUe auf ein Hebelsystem zu übertragen, mit dem eine Auslösung eines Schaltgerätes bewirkt werden kann. Zu diesem Zweck sind Schieberelemente vorhanden, die in Berührung mit den Thermobimetallen stehen. Dabei muß eine Schieberbeweglichkeit auch dann gewährleistet sein, wenn sich lediglich ein Thermobimetall aufgrund eines Überstromes im zugehörigen Netzleiter ausbiegt. Zu diesem Zweck werden zwei Schieberelemente gegeneinander gestellt, die relativ zueinander verschieblich sind, so daß ein Thermobimetall das eine Schieberelement verschiebt, wogegen das andere Schieberelement ortsfest stehen bleibt.Such a slide arrangement for a thermal overcurrent relay has the task of transferring the movement of the thermobimetaUe to a lever system with which a switching device can be triggered. For this purpose, slide elements are available which are in contact with the bimetallic metals. Slider mobility must also be ensured if only a bimetallic element bends due to an overcurrent in the associated network conductor. For this purpose, two slide elements are placed against each other, which are displaceable relative to each other, so that a bimetallic metal displaces one slide element, whereas the other slide element remains stationary.
Aufgabe der Erfindung ist es, eine Schieberanordnung der eingangs genannten Art zu schaffen, bei der Herstellung vereinfacht ist.The object of the invention is to provide a slide arrangement of the type mentioned, which is simplified in the manufacture.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst. This object is achieved by the features of claim 1.
Erfindungsgemäß ist jedes Schieberelement aus drei vorzugsweise aus Isoliermaterial bestehenden Schieberplatten zusammengesetzt, deren Anliegeflächen, die gegen die Bimetalle anliegen, an jeweils unterschiedlichen Ausnehmungen angeordnet sind.According to the invention, each slide element is composed of three slide plates, preferably made of insulating material, the contact surfaces of which lie against the bimetals and are each arranged at different recesses.
Dabei kann jede Schieberplatte eine der Anzahl der Phasen entsprechende Anzahl von U-förmigen, zum gleichen Rand hin offenen Aussparungen aufweisen und an der gleichen Kante an jeweils einer anderen Aussparung jeder Schieberplatte ist jeweils ein Vorsprung vorgesehen, wobei alle Vorsprünge in gleiche Richtung weisen, und zwar in Richtung der Längskante.Each slide plate can have a number of U-shaped recesses corresponding to the number of phases and open to the same edge, and a projection is provided on the same edge on a different recess of each slide plate, with all projections pointing in the same direction, and in the direction of the long edge.
Wenn nun die drei Schieberplatten übereinandergelegt werden, dann erhält man ein Schieberelement, das die Aussparungen aufweist und an jeder der Aussparungen einen entsprechenden Vorsprung besitzt.If the three slide plates are now placed one on top of the other, a slide element is obtained which has the cutouts and has a corresponding projection on each of the cutouts.
Wenn eine Schieberanordnung montiert wird, dann werden zwei Schieberelemente so gegeneinander gestellt, daß die Vorsprünge an einem Schieberelement von einer Seite und die am anderen Schieberelement von der anderen Seite gegen die ThermobimetaUe anliegen.If a slide assembly is mounted, then two slide elements are placed against each other so that the projections on one slide element from one side and the other slide element from the other side against the ThermobimetaUe.
Dadurch daß die einzelnen Vorsprünge eines Schieberelementes in unterschiedlichen Ebenen liegen, greifen die ThermobimetaUe der einzelnen Phasen auch in unterschiedlichen Ebenen und an unterschiedlichen Stellen an jedem Schieberelement an. Um dies zu vermeiden, besitzen wenigstens zwei Schieberplatten im Bereich ihrer Vorsprünge Durchzüge, die jeweils die darunterliegenden Schieberplatten durchgreifen, so daß die Enden der Durchzüge auf einer Ebene enden, wodurch erreicht wird, daß die ThermobimetaUe am Schieberelement immer in der gleichen Ebene angreifen.Because the individual projections of a slide element lie in different planes, the thermobimetaUe of the individual phases also attack in different planes and at different locations on each slide element. In order to avoid this, at least two slide plates have passages in the area of their projections, each of which passes through the slide plates below, so that the ends of the passages end on one level, as a result of which the thermobimetaUe always act on the slide element in the same plane.
Die Herstellung der einzelnen Schieberelemente erfolgt entsprechend den Verfahrensschritten des Anspruches 5. Anhand der Zeichnung, in der zwei Ausführungsbeispiele der Erfindung dargestellt sind, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung näher erläulert und beschrieben werden.The individual slide elements are produced in accordance with the method steps of claim 5. The invention and further advantageous refinements and improvements of the invention are to be explained and described in more detail with reference to the drawing, in which two exemplary embodiments of the invention are shown.

Es sei nun Bezug genommen auf die Fig. 3. Die Fig. 3 zeigt ein Schieberelement 10 einer ersten Ausführungsform, das aus drei Schieberplatten 1 1 , 12 und 13 zusammengesetzt ist.Reference is now made to FIG. 3. FIG. 3 shows a slide element 10 of a first embodiment, which is composed of three slide plates 11, 12 and 13.
Der Aufbau der einzelnen Schieberplatten ist der Fig. 1 zu entnehmen.The structure of the individual slide plates is shown in FIG. 1.
Jede Schieberplatle 11 , 12 und 13 ist ein langgestreckt rechteckiges Bauteil mit drei an einer Längskante angeordneten rechteckigen Ausnehmungen 14, 15, 16 für die Schieberplatte 13, Ausnehmungen 17, 18 und 19 für die Schieberplatte 12 und Ausnehmungen 20, 21 und 22 für die Schieberplatte 11.Each slide plate 11, 12 and 13 is an elongated rectangular component with three rectangular recesses 14, 15, 16 arranged on the longitudinal edge for the slide plate 13, recesses 17, 18 and 19 for the slide plate 12 and recesses 20, 21 and 22 for the slide plate 11th
Die Ausnehmung 16 der Schieberplatte 13 besitzt einen Vorsprung 23, der an der senkrecht zu der Längserstreckung verlaufenden Kante 24 angeformt ist, die dem in der Zeichnung Fig. 1 rechts befindlichen Ende der Schieberplatte 13 entgegengesetzt ist.The recess 16 of the slide plate 13 has a projection 23 which is formed on the edge 24 which extends perpendicular to the longitudinal extension and which is opposite to the end of the slide plate 13 located on the right in the drawing in FIG. 1.
Diesem Vorsprung 23 entsprechen ein Vorsprung 25 in der Schieberplatte 12 und ein Vorsprung 26 in der Schieberplatte 11 in jeweils einer anderen Ausnehmung. Der Schieberplatte 11 , 12 und 13 sind Schieberplatten 1 1 a, 12a und 13a zugeordnet, die entsprechende Ausnehmungen 14a, 15a und 16a bzw. 17a, 18a, 19a bzw. 20a,A projection 25 in the slide plate 12 and a projection 26 in the slide plate 11 each correspond to this projection 23 in a different recess. The slide plate 11, 12 and 13 are assigned slide plates 11a, 12a and 13a, the corresponding recesses 14a, 15a and 16a or 17a, 18a, 19a or 20a,
21 a, 22a aufweisen. Die Schieberplatte 13a besitzt in der Ausnehmung 16a einen Vorsprung 23a, der von derjenigen Kante 24 vorspringt, die der rechten Endkante der Schieberplatte 13a benachbart liegt.21 a, 22 a. The slide plate 13a has a projection 23a in the recess 16a which projects from the edge 24 which is adjacent to the right end edge of the slide plate 13a.
Bei der Schieberplatte 12 befindet sich ein Vorsprung 25a in der Ausnehmung 18a und bei der Schieberplatte 11 a befindet sich ein Vorsprung 26a in der Ausnehmung 20a.In the slide plate 12 there is a projection 25a in the recess 18a and in the slide plate 11a there is a projection 26a in the recess 20a.
Die zusammen gehörenden Schieberplatten 11 , 11 a; 12, 12a und 13, 13a sind nebeneinander gelegt, wobei sie an den aufeinanderzu weisenden Längskanten mittels Verbindungsstücken 27, 28 und 29 miteinander verbunden sind, so daß die beiden Schieberplatten 11 , 1 1 a... jeweils eine vorfertigbare Einheit miteinander bilden. Anstatt dieser Verbindungen 27 beidspielsweise der beiden Schieberplatten 1 1 , 11 a könnte auch eine U-förmige Verbindung 30 vorgesehen sein, die an den rechten Endkanten der Schieberplatten 1 1 , 11 a anschließen, wobei sowohl die Verbindungen 27 als auch die Verbindung 30 vorgesehen sein kann. Die Vorsprünge 26, 26a; 25, 25a; 23, 23a der einander gegenüberliegenden Ausnehmungen 20, 20a; 21 , 21 ; 16, 16a sind dabei gegeneinander gerichtet.The associated slide plates 11, 11 a; 12, 12a and 13, 13a are placed next to one another, being connected to one another at the longitudinal edges to be pointed towards one another by means of connecting pieces 27, 28 and 29, so that the two slide plates 11, 1 1 a ... each form a prefabricated unit with one another. Instead of these connections 27, for example, the two slide plates 11, 11a, a U-shaped connection 30 could also be provided, which connect to the right end edges of the slide plates 11, 11a, both connections 27 and connection 30 being provided can. The projections 26, 26a; 25, 25a; 23, 23a of the mutually opposite recesses 20, 20a; 21, 21; 16, 16a are directed towards each other.
Zur Herstellung der Schieberplattenanordnung werden nun die Schieberplatten 11 , 11 a; 12, 12a und 13, 13a übereinandergelegt, siehe Fig. 2, wobei die Verbindungsstege 27, 28 und 29 noch vorhanden sind. ThermobimetaUe 31 bis 33 greifen in die sich gegenüberliegenden Ausnehmungen im Bereich der entsprechenden Vorsprünge und die Schieberplatten werden so gegeneinander verschoben, daß die Vorsprünge gegen die Flachseiten der ThermobimetaUe, wie in Fig. 2 dargestellt, also beidseitig an den Thermobimetallen zum Anliegen kommen. Danach werden die übereinander liegenden Schieberplatten miteinander verklebt oder verschweißt und die Verbindungen 27, 28 und 29 bzw. die Verbindung 30 getrennt. Damit sind die entsprechenden Vorsprünge an die konkrete Ausführung und Zuordnung der drei ThermobimetaUe zueinander angepaßt und justiert. Die Fig. 3 zeigt die Anordnung gemäß der Fig. 2 im Schnitt: man erkennt im oberen Plättchen 11 die beiden Vorsprünge 26, 26a, die einen Abstand t zwischen sichTo produce the slide plate arrangement, the slide plates 11, 11 a; 12, 12a and 13, 13a superimposed, see Fig. 2, wherein the connecting webs 27, 28 and 29 are still present. ThermobimetaUe 31 to 33 engage in the opposite recesses in the area of the corresponding protrusions and the slide plates are shifted against each other in such a way that the protrusions against the flat sides of the ThermobimetaUe, as shown in FIG. 2, come to rest on the thermobimetals on both sides. The slide plates lying one above the other are then glued or welded to one another and the connections 27, 28 and 29 or the connection 30 are separated. The corresponding projections are thus adapted and adjusted to the specific design and assignment of the three ThermobimetaUe to each other. FIG. 3 shows the arrangement according to FIG. 2 in section: one can see in the upper plate 11 the two projections 26, 26a, which have a distance t between them

In der mittleren Schieberplatte 12 sind die Vorsprünge 25, 25 und in der unteren Schieberplatte die Vorsprünge 23, 23a im Schnitt zu sehen.form, which corresponds to the thickness of the thermobimetal 33. The projections 25, 25 can be seen in the middle slide plate 12 and the projections 23, 23a in the lower slide plate.
Bei der Ausführung nach der Fig. 3 liegen die ThermobimetaUe zwischen den Vorsprüngen an den oberen Schieberplatten, bei den Vorsprüngen 25, 25a an den mittleren Schieberplatten und 23, 23a an der unteren Schieberplatte 13, was zur Folge hat, daß die ThermobimetaUe in unterschiedlichen Höhen mit dem Schieberelement 10 gekoppelt sind.3, the ThermobimetaUe are between the projections on the upper slide plates, the projections 25, 25a on the middle slide plates and 23, 23a on the lower slide plate 13, with the result that the ThermobimetaUe at different heights are coupled to the slide element 10.
Zur Vermeidung einer derartigen unterschiedlichen Kopplung, d. h. Kopplung in unterschiedlicher Höhe, können bei der Ausführung gemäß Fig. 4 in der oberen Schieberplatte 40 Durchzüge 43, 44 und in der mittleren Schieberplatte Durchzüge 45 und 46 vorgesehen sein; diese Durchzüge enden an der unteren freien Fläche der unteren Schieberplatte 42, so daß bei dieser Ausführung die ThermobimetaUe auf das Schieberelement in identischer gleicher Höhe einwirken. To avoid such a different coupling, i. H. Coupling at different heights, in the embodiment according to FIG. 4, passages 43, 44 can be provided in the upper slide plate 40 and passages 45 and 46 in the middle slide plate; these passages end on the lower free surface of the lower slide plate 42, so that in this embodiment the ThermobimetaUe act on the slide element at an identical height.
