Definitions
- the invention relates to a contact arrangement for a relay with a contact spring, the spring leg of which is attached at one end and is biased with its free end against a counter-contact element by at least one pretensioning bend extending transversely to its longitudinal direction, the free end in the closed state of contact with a contact piece rests on the mating contact element and is lifted from the mating contact element in the opened state of the contact by an actuating or supporting element, which acts on the contact spring in the region between the pretension bend and the free end of the contact spring by means of a contact edge running transversely to the longitudinal direction of the contact spring.
- the object of the invention is to develop a contact arrangement of the type mentioned in such a way that the tendency to bounce, which is one of the causes of the welding, is reduced when the contacts are closed and that the opening of welded contacts is facilitated when opening.
- this object is achieved in that the bend line of the biasing bend of the contact spring runs at an acute angle with respect to the contact edge of the actuating or supporting member.
- the biasing bend running obliquely to the contact edge or the actuating edge ensures that the spring receives a torsional movement both when the contact is closed and when it is opened, as a result of which a lateral rolling off at the contact point is forced. As a result, the impact energy is partially converted into friction when closing, which leads to a reduction in the tendency to bounce. Due to the oblique preload buckle, the actuating member also asymmetrically engages the contact spring when the contact is opened, as a result of which an additional torsional force also acts on a welded contact point and facilitates tearing open.
- the contact spring is supported in an area between the oblique bias bend and the contact point on an edge of the armature.
- an inclined pretensioning kink also in another relay structure, the edge of an actuating or supporting member taking the place of the anchor edge.
- two or more can be provided instead of the one pre-tensioning buckle. These can then run parallel to one another or also at an angle to one another. Since there must be a moment for a torsion of the spring, it is possible in the case of springs with two pretensioning bends to provide one bend parallel to the support edge and a second bend obliquely to this; However, both kinks can also be attached in the same direction at an angle or in opposite directions at an angle.
- the angle between the pretension bend and the contact edge should be between 0 and 30 °. Good results have been obtained at an angle of the order of 5 °.
- the distance of the kink or kinks to the clamping point depends on the geometry of the spring and the desired angle of impact on the counter contact.
- the size of the wobble of the contact, which results from the deflection and the torsion of the spring, is also important. Therefore, a relatively large overstroke should be provided when closing the contacts.
- the biasing force with which the spring is biased against the actuator should be about 20 to 30% of the contact force. If it is a counter-contact spring biased against a support plate, this proportion will generally be higher.
- a contact spring 5 is connected to the armature and carries a contact piece 6 at its free end 5a and cooperates with a mating contact element 7 anchored in the coil former 1 or its contact piece 8.
- the contact spring 5 is biased in the area between its attachment point 9 on the armature 4 and the free end 5a towards the armature and thus towards the mating contact element 7.
- This pretension is generated by an obliquely running pretension kink 10, which generates a certain contact force F on the anchor edge 4a.
- the angle between the contact edge 4a and the pretension bend 10 can be between 0 and 30 °. It is preferably in the range from approximately 5 ° to 10 °.
- the preload bend 10 causes the contact piece 6 to roll on the contact piece 8 when the contact is closed and when it opens, which leads to a reduction in the bouncing and easier tearing of the contact with slight welding.
- FIG. 3 and 4 show a further embodiment of a contact arrangement designed according to the invention, the relay system no longer being shown.
- an armature 14 (which is only shown in part) is coupled to a movable contact spring 15, that is to say it is directly connected or is also actuated via an intermediate element, the contact piece 16 of which cooperates with a contact piece 18 of a mating contact spring 17.
- the moving contact spring 15 can be more or less rigidly connected to the armature, since it does not require high elasticity. Because in this case the counter contact spring is also 17th elastic, so it can absorb the overstroke of the armature when the contact closes.
- the counter-contact spring 17 is biased by a bias bias 20 against a support plate 19, wherein it rests on the edge 19a of this support plate in the idle state.
- the effect of the oblique preload bend is the same as in the example previously described. In this case, however, the preload is higher and almost the same as the contact force. Otherwise, all configuration options of the previous example also apply to the example according to FIGS. 3 and 4.

Description
Die Erfindung betrifft eine Kontaktanordnung für ein Relais mit einer Kontaktfeder, deren Federschenkel mit einem Ende befestigt ist und mit seinem freien Ende gegen ein Gegenkontaktelement durch mindestens einen quer zu seiner Längsrichtung verlaufenden Vorspannknick vorgespannt ist, wobei das freie Ende im Schließzustand des Kontaktes mit einem Kontaktstück auf dem Gegenkontaktelement aufliegt und im Öffnungszustand des Kontaktes durch ein Betätigungs- oder Abstützorgan von dem Gegenkontaktelement abgehoben ist, welches mittels einer quer zur Längsrichtung der Kontaktfeder verlaufenden Auflagekante an der Kontaktfeder im Bereich zwischen dem Vorspannknick und dem freien Ende der Kontaktfeder angreift.The invention relates to a contact arrangement for a relay with a contact spring, the spring leg of which is attached at one end and is biased with its free end against a counter-contact element by at least one pretensioning bend extending transversely to its longitudinal direction, the free end in the closed state of contact with a contact piece rests on the mating contact element and is lifted from the mating contact element in the opened state of the contact by an actuating or supporting element, which acts on the contact spring in the region between the pretension bend and the free end of the contact spring by means of a contact edge running transversely to the longitudinal direction of the contact spring.
Relais mit derartigen Kontaktanordnungen gibt es in großer Zahl. Beispielsweise ist ein derartiges Relais in dem DE-GM 82 35 283 gezeigt. Derartige Relais mit einfachem Aufbau, wobei häufig die Kontaktfeder unmittelbar mit dem Anker verbunden ist, der Anker also selbst das Betätigungselement darstellt, werden vielfach zum Schalten hoher (Gleichstrom-) Lasten eingesetzt. Ein Anwendungsfall ist beispielsweise das Schalten von Lampenstromkreisen in Kraftfahrzeugen, wobei hohe Stromspitzen bis zu 180 A auftreten können. Bei derartig hohen Schaltlasten mit Lichtbogenbildung, insbesondere bei prellendem Einschalten, kommt es häufig zum Verschweißen der Kontakte und damit zum Ausfall des Relais. Um jedoch einen frühzeitigen Ausfall des Relais zu verhindern, ist es erforderlich, hohe Aufreißkräfte zu erreichen, so daß geringfügig verschweißte Kontakte wieder geöffnet werden können und das Relais funktionsfähig bleibt. Hierzu ist es bekannt, hohe Federkräfte für die Rückstellung der Kontaktfeder bereitzustellen, was natürlich eine entsprechende Erhöhung der Anzugskräfte und der Ansprecherregung mit sich bringt. Von Vorteil ist es auch, beim Schließen des Kontaktes einen großen Überhub des Ankers vorzusehen. Wegen der bereits erwähnten erhöhten Erregerleistung kann jedoch die Vorspannung bzw. die erhöhte Rückstellkraft nicht beliebig hoch gewählt werden.Relays with such contact arrangements exist in large numbers. For example, such a relay is shown in DE-GM 82 35 283. Relays of this type with a simple construction, the contact spring frequently being connected directly to the armature, that is to say the armature itself being the actuating element, are often used for switching high (direct current) loads. One application is, for example, the switching of lamp circuits in motor vehicles, where high current peaks of up to 180 A can occur. With such high switching loads with arcing, especially when bouncing on, the contacts are often welded and the relay fails. However, in order to prevent the relay from failing prematurely, it is necessary to achieve high tearing forces so that slightly welded contacts can be opened again and the relay remains functional. For this purpose, it is known to provide high spring forces for the resetting of the contact spring, which of course means a corresponding increase in the tightening forces and Brings with it excitement. It is also advantageous to provide a large overstroke of the armature when the contact closes. Because of the already mentioned increased excitation power, however, the preload or the increased restoring force cannot be chosen to be arbitrarily high.
Aufgabe der Erfindung ist es, eine Kontaktanordnung der eingangs genannten Art so weiterzubilden, daß die Prellneigung, die mit eine Ursache für das Verschweißen ist, beim Schließen der Kontakte vermindert wird und daß beim Öffnen das Aufreißen verschweißter Kontakte erleichtert wird.The object of the invention is to develop a contact arrangement of the type mentioned in such a way that the tendency to bounce, which is one of the causes of the welding, is reduced when the contacts are closed and that the opening of welded contacts is facilitated when opening.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Knicklinie des Vorspannknicks der Kontaktfeder gegenüber der Auflagekante des Betätigungs- oder Abstützorgans unter einem spitzen Winkel verläuft.According to the invention, this object is achieved in that the bend line of the biasing bend of the contact spring runs at an acute angle with respect to the contact edge of the actuating or supporting member.
Durch den schräg zur Auflagekante oder Betätigungskante verlaufenden Vorspannknick wird erreicht, daß sowohl beim Schließen als auch beim Öffnen des Kontaktes die Feder eine Torsionsbewegung erhält, wodurch ein seitliches Abrollen an der Kontaktstelle erzwungen wird. Dadurch wird die Aufschlagenergie beim Schließen zum Teil in Reibung umgesetzt, was zu einer Verringerung der Prellneigung führt. Aufgrund des schrägen Vorspannknicks greift außerdem das Betätigungsorgan auch beim Öffnen des Kontaktes unsymmetrisch an der Kontaktfeder an, wodurch auch an einer verschweißten Kontaktstelle eine zusätzliche Torsionskraft wirkt und das Aufreißen erleichtert.The biasing bend running obliquely to the contact edge or the actuating edge ensures that the spring receives a torsional movement both when the contact is closed and when it is opened, as a result of which a lateral rolling off at the contact point is forced. As a result, the impact energy is partially converted into friction when closing, which leads to a reduction in the tendency to bounce. Due to the oblique preload buckle, the actuating member also asymmetrically engages the contact spring when the contact is opened, as a result of which an additional torsional force also acts on a welded contact point and facilitates tearing open.
Wenn das Betätigungsorgan unmittelbar ein Anker ist, auf welchem die Kontaktfeder aufliegt, stützt sich die Kontaktfeder in einem Bereich zwischen dem schräg verlaufenden Vorspannknick und der Kontaktstelle an einer Kante des Ankers ab. Es wäre aber auch denkbar, einen derart schräg verlaufenden Vorspannknick auch bei einem anderen Relaisaufbau anzuwenden, wobei an die Stelle der Ankerkante die Kante eines Betätigungs- oder Abstützorgans tritt.If the actuating member is an armature directly, on which the contact spring rests, the contact spring is supported in an area between the oblique bias bend and the contact point on an edge of the armature. However, it would also be conceivable to use such an inclined pretensioning kink also in another relay structure, the edge of an actuating or supporting member taking the place of the anchor edge.
Zur Erzielung eines größtmöglichen Überhubes kann man anstelle des einen Vorspannknicks auch zwei oder mehrere vorsehen. Diese können dann parallel zueinander oder auch in einem Winkel zueinander verlaufen. Da für eine Torsion der Feder ein Moment vorhanden sein muß, ist es bei Federn mit zwei Vorspannknicken möglich, den einen Knick parallel zur Auflagekante und einen zweiten Knick schräg zu dieser vorzusehen; es könen aber auch beide Knicke gleichsinnig schräg oder gegensinnig schräg zueinander angebracht werden.To achieve the greatest possible overstroke, two or more can be provided instead of the one pre-tensioning buckle. These can then run parallel to one another or also at an angle to one another. Since there must be a moment for a torsion of the spring, it is possible in the case of springs with two pretensioning bends to provide one bend parallel to the support edge and a second bend obliquely to this; However, both kinks can also be attached in the same direction at an angle or in opposite directions at an angle.
Der Winkel zwischen dem Vorspannknick und der Auflagekante sollte insgesamt zwischen 0 und 30° betragen. Gute Ergebnisse wurden beim einem Winkel in der Größenordnung von 5° erzielt.The angle between the pretension bend and the contact edge should be between 0 and 30 °. Good results have been obtained at an angle of the order of 5 °.
Der Abstand des Knickes oder der Knicke zur Einspannstelle ist von der Geometrie der Feder und dem gewünschten Auftreffwinkel auf dem Gegenkontakt abhängig. Wichtig ist außerdem die Größe der Taumelbewegung des Kontaktes, die sich aus der Durchbiegung und der Torsion der Feder ergibt. Deshalb ist ein relativ großer Überhub beim Schließen der Kontakte vorzusehen.The distance of the kink or kinks to the clamping point depends on the geometry of the spring and the desired angle of impact on the counter contact. The size of the wobble of the contact, which results from the deflection and the torsion of the spring, is also important. Therefore, a relatively large overstroke should be provided when closing the contacts.
Die Vorspannkraft, mit der die Feder gegen das Betätigungsglied, beispielsweise den Anker, vorgespannt ist, sollte etwa 20 bis 30 % der Kontaktkraft betragen. Wenn es sich um eine gegen eine Stützplatte vorgespannte Gegenkontaktfeder handelt, wird dieser Anteil in der Regel höher sein.The biasing force with which the spring is biased against the actuator, for example the armature, should be about 20 to 30% of the contact force. If it is a counter-contact spring biased against a support plate, this proportion will generally be higher.
Die Erfindung wird nachfolgend an einem Ausführungsbeispiel anhand der Zeichnung näher erläutert. Es zeigt
- FIG 1 ein schematisch dargestelltes Relaissystem mit einer am Anker befestigten und abgestützten Kontaktfeder,
- FIG 2 eine stirnseitige Ansicht auf den Anker mit der Kontaktfeder,
- FIG 3 und 4 eine Kontaktanordnung mit einer einen schräg verlaufenden Knick aufweisenden Gegenkontaktfeder in zwei Ansichten.
- 1 shows a schematically illustrated relay system with a contact spring fastened and supported on the armature,
- 2 shows an end view of the armature with the contact spring,
- 3 and 4 show a contact arrangement with a counter-contact spring with an inclined kink in two views.
In FIG 1 ist schematisch ein Relaissystem mit einem Spulenkörper 1, einer Wicklung 2, einem Joch 3 und einem am Joch gelagerten flachen Anker 4 dargestellt. Mit dem Anker ist eine Kontaktfeder 5 verbunden, die an ihrem freien Ende 5a ein Kontaktstück 6 trägt und mit einem im Spulenkörper 1 verankerten Gegenkontaktelement 7 bzw. dessen Kontaktstück 8 zusammenwirkt. Die Kontaktfeder 5 ist im Bereich zwischen ihrer Befestigungsstelle 9 am Anker 4 und dem freien Ende 5a zum Anker hin und damit zum Gegenkontaktelement 7 hin vorgespannt. Diese Vorspannung wird durch einen schräg verlaufenden Vorspannknick 10 erzeugt, der an der Ankerkante 4a eine bestimmte Auflagekraft F erzeugt. Der Winkel zwischen der Auflagekante 4a und dem Vorspannknick 10 kann zwischen 0 und 30° betragen. Vorzugsweise liegt er im Bereich von etwa 5° bis 10°.1 schematically shows a relay system with a coil former 1, a winding 2, a
Durch den Vorspannknick 10 wird beim Schließen und beim Öffnen des Kontaktes ein Abrollen des Kontaktstücks 6 auf dem Kontaktstück 8 erreicht, was zu einer Verminderung des Prellens und zu einem leichteren Aufreißen des Kontakts bei einer leichten Verschweißung führt.The
In den FIG 3 und 4 ist eine weitere Ausführungsform einer erfindungsgemäß gestalteten Kontaktanordnung gezeigt, wobei das Relaissystem nicht mehr dargestellt ist. Bei dieser Ausführungsform ist ein Anker 14 (der nur teilweise dargestellt ist) mit einer bewegbaren Kontaktfeder 15 gekoppelt, d. h. unmittelbar verbunden oder auch über ein Zwischenorgan betätigt, dessen Kontaktstück 16 mit einem Kontaktstück 18 einer Gegenkontaktfeder 17 zusammenwirkt. Die bewegt Kontaktfeder 15 kann dabei mehr oder weniger starr mit dem Anker verbunden sein, da sie keine hohe Elastizität benötigt. Denn in diesem Fall ist auch die Gegenkontaktfeder 17 elastisch, sie kann also beim Schließen des Kontaktes den Überhub des Ankers aufnehmen. Die Gegenkontaktfeder 17 ist dabei durch einen schräg verlaufenden Vorspannknick 20 gegen eine Abstützplatte 19 vorgespannt, wobei sie im Ruhezustand an der Kante 19a dieser Abstützplatte aufliegt. Die Wirkung des schrägen Vorspannknicks ist die gleiche wie bei dem vorher beschriebenen Beispiel. Die Vorspannkraft ist allerdings in diesem Fall höher und liegt nahezu in der Höhe der Kontaktkraft. Ansonsten gelten alle Ausgestaltungsmöglichkeiten des vorherigen Beispiels auch für das Beispiel gemäß FIG 3 und 4.3 and 4 show a further embodiment of a contact arrangement designed according to the invention, the relay system no longer being shown. In this embodiment, an armature 14 (which is only shown in part) is coupled to a
