Abstract

The carrier arms (4) have contact strip pads (5)on the underside that act as bridging contacts for fixed contacts in the relay. The carriers are moulded into a plastic center block (13) and are displaced by a pivot mounted armature. The section of the thin contact carrier is reduced to allow torsion to take place and so accommodate any inaccuracies in alignment.

Description

Die Erfindung betrifft ein Relais mit einem Sockel, durch dessen Boden eine Grundebene festgelegt ist, einem mittig gelagerten Anker, der Teil eines Magnetsystems ist, und einer Kontaktfeder, die an einem mittleren Abschnitt mit dem Anker verbunden ist, so daß die Kontaktfeder und der Anker eine gemeinsame Lagerachse besitzen, und die an ihrem freien Ende Brückenkontakte trägt.The invention relates to a relay with a base, by the bottom of which is defined as a basic level, a central one Anchor, which is part of a magnet system, and one Contact spring attached to a middle section with the anchor is connected so that the contact spring and the armature are common Own bearing axis, and that at its free end Bridge contacts carries.

Derartig aufgebaute Relais sind für viele Anwendungen bereits bekannt, wobei durch die Verwendung von Brückenkontakten das Schaltvermögen für hohe Ströme verbessert wird. Allerdings weisen die Gegenkontakte, die durch die Brückenkontakte verbindbar sind, fertigungsbedingte Toleranzen insbesondere in der Höhe auf. Dadurch besteht die Gefahr, daß auf die beiden Gegenkontakte ein unterschiedlich großer Kontaktdruck ausgeübt wird.Relays constructed in this way are already available for many applications known, by using bridge contacts Switching capacity for high currents is improved. Indeed have the mating contacts that can be connected by the bridge contacts are manufacturing tolerances especially in of height. This creates the risk that the two Counter-contacts exerted a different contact pressure becomes.

Eine Verbesserung dieser Konstruktion offenbart die JP 53-6851. Bei diesem Relais weist die Kontaktfeder auf beiden Seiten der Lagerachse jeweils zwei Arme auf, die sich unabhängig voneinander biegen können. Es besteht jedoch das Problem, daß der Aufbau komplizierter wird und der Stromfluß über die gesamte Länge der beiden Kontaktfederarme läuft. Die Kontaktfeder muß daher aus einem relativ gut leitfähigen Material bestehen, das aber schlechtere mechanische Eigenschaften aufweist.An improvement of this construction is disclosed in JP 53-6851. With this relay, the contact spring points to both Sides of the bearing axis each have two arms that are independent can bend from each other. However, there is the problem that the structure becomes more complicated and the current flow runs over the entire length of the two contact spring arms. The Contact spring must therefore be made of a relatively good conductive material exist, but the poorer mechanical properties having.

Aufgabe der Erfindung ist es deshalb, ein Relais der eingangs genannten Art zu schaffen, bei dem die Kontaktfeder möglichst einfach geformt ist, aber trotzdem den gleichen Kontaktdruck an allen Kontaktstellen gewährleistet, und gleichzeitig einen geringen Durchgangswiderstand ermöglicht. The object of the invention is therefore a relay of the input to create the type mentioned, in which the contact spring if possible is simply shaped, but still has the same contact pressure guaranteed at all contact points, and at the same time one low volume resistance.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Kontaktfeder auf jeder Seite der Lagerachse einen Kontaktarm bildet, der jeweils zwischen der Lagerachse und dem freien Ende einen durch Verengungen gebildeten Torsionssteg aufweist.According to the invention this object is achieved in that the Contact spring a contact arm on each side of the bearing axis forms, each between the bearing axis and the free End has a torsion bar formed by constrictions.

Durch die erfindungsgemäße Ausbildung der Kontaktfeder besitzen die Kontaktarme eine verbesserte Torsionsfähigkeit, so daß der Höhenausgleich zu den Festkontakten möglich ist. Wenn die freien Ankerenden stark verbreitert sind, so daß die Kontaktarme ungefähr T-förmig sind, können die Festkontakte relativ weit auseinander liegen und so eine hohe Spannungsfestigkeit zueinander aufweisen. Der Strompfad von einem Festkontakt zu dem anderen verläuft ausschließlich über einen Brückenkontakt, so daß das Material der Kontaktfeder für die Stromtragfähigkeit keine Rolle spielt. Für dieses kann somit ein Material mit mechanisch günstigen Eigenschaften verwendet werden.Owing to the inventive design of the contact spring the contact arms have an improved torsional ability, so that the height compensation to the fixed contacts is possible. If the free anchor ends are greatly widened, so that the contact arms are approximately T-shaped, the fixed contacts can be relative are far apart and thus have a high dielectric strength to each other. The current path from a fixed contact to the other runs exclusively over one Bridge contact, so that the material of the contact spring for the Current carrying capacity doesn't matter. For this, therefore uses a material with mechanically favorable properties become.

In einer vorteilhaften Ausgestaltung weist die Kontaktfeder in einem mittleren Bereich seitliche Trägerarme auf, die mit einem feststehenden Relaisteil verbunden sind. Dabei können sowohl die Trägerarme als auch die festen Relaisteile zu dem Sockelboden senkrecht stehende Flächen aufweisen, so daß beim Einsetzen der Kontaktfeder der Abstand zwischen den Brückenkontakten und Festkontakt eingestellt und beispielsweise durch Schweißen werden kann.In an advantageous embodiment, the contact spring in a central area on the side support arms with a fixed relay part are connected. You can both the support arms and the fixed relay parts to the Base floor have vertical surfaces so that when Insert the contact spring the distance between the bridge contacts and fixed contact set and for example can be by welding.

The invention is explained in more detail using an exemplary embodiment with reference to the drawings. It shows:

Figur 1 zeigt ein erfindungsgemäßes Relais, wobei ein Teil eines Gehäuses 22 aufgeschnitten ist. Das Gehäuse 22 besteht aus einem Sockel 1 und einer Kappe. Im Inneren ist das Magnetsystem 20 mit einer Spule 21, einem Kern 23 mit Polschuhen 24 und einem Dauermagneten 25 erkennbar. Diese Anordnung entspricht der eines üblichen polarisierten Relais. Zwischen dem Dauermagneten 25 und dem Sockel 1 befinden sich ein Anker 2 und ein Kontaktsystem mit einer Kontaktfeder 3.Figure 1 shows a relay according to the invention, with a part a housing 22 is cut open. The housing 22 is made from a base 1 and a cap. Inside is the magnet system 20 with a coil 21, a core 23 with pole pieces 24 and a permanent magnet 25 can be seen. This arrangement corresponds to that of a conventional polarized relay. Between the permanent magnet 25 and the base 1 are an anchor 2 and a contact system with a contact spring 3.

In Figur 2 ist die Kontaktfeder 3 detailliert dargestellt. In der Figur ist sie in einem mittleren Bereich in ein Kunststoffformteil 13 eingebettet. Dieses Kunststoffformteil 13 dient unter anderem zur Verbindung der Kontaktfeder 3 mit dem Anker 2. In ungefähr der Mitte der Kontaktfeder 3 sind seitlich zwei Trägerarme 9 ausgebildet. An diesen Trägerarmen 9 ist die Kontaktfeder 3 an einem feststehenden Relaisteil 10 befestigt, wie in der Beschreibung zu Figur 3 näher ausgeführt ist. Außerdem bilden die Trägerarme 9 eine Rückstellfeder für die Kontaktfeder 3 und den Anker 2. An den freien Kontaktfederenden 4 sind Brückenkontakte 5 befestigt. Je einer der Brückenkontakte überbrückt zwei Gegenkontakte 12, die in den Sockel 1 eingebettet sind (vgl. Figur 3). Ausgehend von der Lagerachse der Kontaktfeder 3, die durch die beiden Trägerarme 9 festgelegt ist, verringert sich die Breite der Kontaktarme 6 hin zu den freien Kontaktfederenden 4, so daß sich ein trapezförmiger Abschnitt 8 ergibt. Die schmalste Stelle der Kontaktarme 6 befindet sich nahe dem freien Kontaktfederende 4, wo die Brückenkontakte 5 aufgesetzt sind. Die Form, die sich für jeden Kontaktarm 6 ergibt, ähnelt der eines T. Durch die Verengung ist an jedem Kontaktarm 9 ein Torsionssteg 7 gebildet, wodurch das Torsionsverhalten der Brückenkontakte 5 zum Ausgleich von Höhentoleranzen der Gegenkontakte 12 verbessert ist. In einer Weiterbildung der Erfindung, die jedoch in dem Ausführungsbeispiel nicht gezeigt ist, kann die Kontaktfeder 3 durch beispielsweise an den Anker 2 angeformte Stützlappen, die unter die Kontaktfeder 3 greifen, im Aufreißen der Kontakte 5 und 12 verbessert werden, auch wenn diese verschweißt sind.In Figure 2, the contact spring 3 is shown in detail. In of the figure, it is in a central area in a plastic molding 13 embedded. This molded plastic part 13 serves among other things to connect the contact spring 3 with the Armature 2. In about the middle of the contact spring 3 are on the side two support arms 9 are formed. On these support arms 9 is the contact spring 3 on a fixed relay part 10 attached, as detailed in the description of Figure 3 is. In addition, the support arms 9 form a return spring for the contact spring 3 and the armature 2. On the free Contact spring ends 4, bridge contacts 5 are attached. One each the bridge contacts bridges two counter contacts 12, the are embedded in the base 1 (see FIG. 3). Outgoing from the bearing axis of the contact spring 3 through the two Carrier arms 9 is fixed, the width of the Contact arms 6 towards the free contact spring ends 4, so that there is a trapezoidal section 8. The narrowest The position of the contact arms 6 is near the free end of the contact spring 4, where the bridge contacts 5 are placed. The shape that results for each contact arm 6 is similar to that of a T. Due to the narrowing there is a contact arm 9 on each Torsion bar 7 is formed, whereby the torsional behavior of the Bridge contacts 5 to compensate for height tolerances of the counter contacts 12 is improved. In a further development of the invention, which, however, are not shown in the exemplary embodiment is, the contact spring 3 by, for example, the armature 2 molded support tabs, which are under the contact spring 3 grip, can be improved by tearing the contacts 5 and 12, even if they are welded.

Figur 3 zeigt, wie die Sockelbaugruppe eines erfindungsgemäßen Relais aussehen könnte. In dem Sockel 1 sind in einem mittleren Bereich zwei Trägerstifte 10 vorgesehen. Die Trägerarme 9 und die Trägerstifte 10 weisen zueinander parallele Flächen auf, die senkrecht zu der Grundebene stehen. Diese Anordnung birgt den Vorteil, daß bei der Montage die Baugruppe aus Kontaktfeder 3 und Anker 2 von oben eingesetzt und soweit nach unten verschoben werden kann, bis der Abstand zwischen den Brückenkontakten 5 und den Gegenkontakten 12 einem vorgegebenen Maß entspricht. Durch beabsichtigtes Schrägeeinsetzen der Baugruppe aus Kontaktfeder 3 und Anker 2 kann ein monostabiles Verhalten des Relais erreicht werden. Bei schräg eingesetzter Kontaktfeder 3 ist bei unerregtem Magnetsystem ein definierter Brückenkontakt 5 in Kontakt mit den zugehörigen Gegenkontakten 12.Figure 3 shows how the base assembly of an inventive Relay could look like. In the base 1 are in one middle area two support pins 10 are provided. The support arms 9 and the carrier pins 10 have mutually parallel Surfaces that are perpendicular to the base plane. This Arrangement has the advantage that the assembly during assembly from contact spring 3 and armature 2 inserted from above and so far can be moved down until the distance between the bridge contacts 5 and the counter contacts 12 one corresponds to the specified dimension. By intentional insertion the assembly of contact spring 3 and armature 2 can monostable behavior of the relay can be achieved. At oblique The inserted contact spring 3 is with the magnet system not excited a defined bridge contact 5 in contact with the associated Mating contacts 12.

Die Verbindung des Ankers 2 mit der Kontaktfeder 3 ist auf vorteilhafte Weise dadurch realisiert, daß das die Kontaktfeder 3 im mittleren Bereich umgebende Kunststoffformteil 13 zwei Zapfen 14 aufweist, auf die der Anker 2 mit entsprechenden Ausnehmungen aufgesetzt und durch Verformen der Zapfen 14 befestigt ist. Der Anker 2 weist im mittleren Bereich eine Wölbung 11 nach oben auf. Diese Wölbung 11 verläuft in ungefähr der Form eines Halbzylinders und liegt an einem festen Relaisteil, in diesem Ausführungsbeispiel dem Dauermagneten 25, an, so daß sie auf diesem abrollen kann. Dies ist insofern ein weiterer Vorteil, daß so die Trägerarme 9 nur für die Rückstellung der Kontaktfeder 3 und des Ankers 2 zuständig sind, und nicht noch zusätzliche Kräfte, die durch das erregte Magnetsystem 20 auf den Anker 2 wirken, aufnehmen müssen. Zudem ist auf diese Weise ein enger Kontakt des Ankers 2 mit der Kernanordnung gegeben, was sich positiv auf die Effizienz des Magnetsystems 20 auswirkt.The connection of the armature 2 with the contact spring 3 is open advantageously realized in that the contact spring 3 plastic molding 13 surrounding in the middle area has two pins 14 on which the armature 2 with corresponding Recesses placed and by deforming the pin 14th is attached. The anchor 2 has one in the central area Curvature 11 upwards. This curvature 11 runs approximately the shape of a half-cylinder and lies on a fixed one Relay part, in this embodiment the permanent magnet 25, so that it can roll on this. This is so far another advantage that the support arms 9 only for the resetting of the contact spring 3 and the armature 2 is responsible are, and not yet additional forces caused by the excited magnet system 20 act on the armature 2, record have to. In addition, the anchor is in close contact in this way 2 given with the core arrangement, which is positive affects the efficiency of the magnet system 20.

Für den Fall, daß ein erfindungsgemäßes Relais einen Mittelanschluß besitzen soll, kann die Kontaktfeder 3 aus einem elektrisch gut leitenden Material bestehen, beispielsweise einer Kupferlegierung. In diesem Fall könnten die Trägerstifte 10, mit denen die Trägerarme 9 der Kontaktfeder 3 verschweißt sind, als Anschlußelemente ausgeführt werden.In the event that a relay according to the invention has a center connection should have, the contact spring 3 from one electrically good conductive material, for example a copper alloy. In this case the carrier pins could 10, with which the support arms 9 of the contact spring 3 are welded are designed as connection elements.
