Description

Die Erfindung betrifft ein Kontaktsystem, insbesondere für ein elektromechanisches Schaltgerät, beispielsweise Schütz, Positionsschalter, Befehls- und Meldegerät oder Schützsicherheitskombination.The invention relates to a contact system, in particular for an electromechanical switching device, for example contactor, Position switch, command and signaling device or contactor safety combination.

Ein derartiges Kontaktsystem weist sowohl einen festen Kontakt als auch einen beweglichen Kontakt auf. Der feste Kontakt dient dabei zur Kontaktierung einer Anschlussleitung oder dergleichen. Der bewegliche Kontakt dient zum Öffnen und Schließen des Kontaktsystems. Hierfür muss der bewegliche Kontakt derart gelagert sein, dass die Schaltstücke des beweglichen und des festen Kontaktes in definierter Art und Weise aufeinandertreffen. Für eine sichere Kontaktierung ist zudem das Aufbringen einer definierten Kontaktierungskraft erforderlich. Außerdem soll der bewegliche Kontakt von seinem Antriebs- oder Betätigungselement, beispielsweise einem Magnetantrieb, Schieber, Schaltstückträger, Sprungsystem oder ähnlichem, zur Vermeidung negativer kinetischer Einflüsse weitgehend entkoppelt sein.Such a contact system has both a firm contact as well as a moving contact. The solid contact serves for contacting a connecting cable or similar. The movable contact is used for opening and Close the contact system. For this, the mobile must Contact be stored so that the switching pieces of the movable and firm contact in a defined way and Way meet. For a secure contact is In addition, the application of a defined contacting force required. In addition, the movable contact of his Drive or actuating element, for example a magnetic drive, Slide, contact piece carrier, jump system or similar, to avoid negative kinetic influences be largely decoupled.

Hierzu ist es aus dem Stand der Technik bekannt, den beweglichen Kontakt mittels einer Metallfeder zu lagern, welche direkt oder indirekt, beispielsweise über einen beweglichen Kontakthalter oder ein Sprungsystem, den beweglichen Kontakt beaufschlagt. Diese Metallfeder führt nicht nur zu einer Verkürzung der Luft- und Kriechstrecken, sondern verursacht auch als zusätzliches Bauteil höhere Material- und Montagekosten und erhöht das Fehlerrisiko der gesamten Baugruppe.For this purpose, it is known from the prior art, the movable Contact by means of a metal spring, which directly or indirectly, for example via a mobile Contact holder or a jump system, the moving contact applied. This metal spring not only leads to a shortening the creepage distances, but also causes as an additional component higher material and assembly costs and increases the risk of error for the entire assembly.

Aufgabe der Erfindung ist es, ein Kontaktsystem bereitzustellen, das einen vergleichsweise geringen Bauraum benötigt. The object of the invention is to provide a contact system, which requires a comparatively small space.

Diese Aufgabe wird durch ein Kontaktsystem nach Anspruch 1 gelöst. Danach weist das Kontaktsystem einen festen Kontakt, insbesondere zur Kontaktierung einer Anschlussleitung, sowie einen von einem Antriebs- oder Betätigungselement betätigbaren bewegliche Kontakt zum Öffnen und Schließen der elektrischen Verbindung mit dem festen Kontakt auf. Darüber hinaus ist ein Kontakthalter zur Aufnahme des beweglichen Kontaktes vorgesehen. Mit dem Kontakthalter verbunden ist ein Federelement aus einem elektrisch nicht leitenden Werkstoff. Dieses Federelement dient der Federung des beweglichen Kontaktes.This object is achieved by a contact system according to claim 1 solved. Thereafter, the contact system has a fixed contact, in particular for contacting a connecting line, as well one actuatable by a drive or actuator movable contact for opening and closing the electrical Connection with the firm contact on. Furthermore is a contact holder for receiving the movable contact intended. Connected to the contact holder is a spring element made of an electrically non-conductive material. This Spring element serves to support the movable contact.

Ein Kerngedanke der Erfindung ist es, den bisher für das Federelement verwendeten Federwerkstoff zu substituieren. Anstelle einer metallischen Feder wird nun ein elektrisch nicht leitendes Federelementeingesetzt. Luft- und Kriechstrecken werden nicht verkürzt, wodurch eine deutliche Reduzierung des erforderlichen Bauraumes möglich ist.A core idea of the invention is the previously for the spring element substituted spring material to substitute. Instead of A metallic spring will not be an electric one now conductive spring elements used. Clearances and creepage distances are not shortened, resulting in a significant reduction of the required space is possible.

Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are in the subclaims specified.

Besteht der Kontakthalter ebenfalls aus einem elektrisch nicht leitenden Material, können negative Einflüsse auf die Lagerstelle von Federelement und Kontakthalter oder die Position des beweglichen Kontaktes bei Erwärmung oder Kühlung können in diesem Fall aufgrund weitestgehend gleicher Temperaturausdehnungskoeffizienten weiter verringert werden.Is the contact holder also made of an electrical non-conductive material, can have negative influences on the Bearing point of spring element and contact holder or the position of the moving contact during heating or cooling can in this case due largely the same temperature expansion coefficient be further reduced.

Bei dem Material für das Federelement handelt es sich gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung um ein Thermoplast (wie beispielsweise PES, PESU, PEI, PPS, POM, PA) oder ein Elastomer. Das ungünstige Nachschwingen des beweglichen Kontaktes wird im Vergleich zur Verwendung einer Metallfeder reduziert, da derartige Werkstoffe eine größere Dämpfungskonstante als Metall aufweisen. The material for the spring element is according to a further advantageous embodiment of the invention to a thermoplastic (such as PES, PESU, PEI, PPS, POM, PA) or an elastomer. The unfavorable ringing of the movable Contact is compared to using a Metal spring reduced because such materials have a larger Have damping constant as metal.

Die Verwendung von Kunststoffen wie Thermoplasten oder Elastomeren erlaubt zugleich eine Integration von Funktionsflächen am Kontakthalter. Hierdurch kann die Baugruppe montageoptimiert gestaltet sein, beispielsweise Führungs- und Lagerflächen aufweisen. Dies reduziert Entwicklungs-, Material- und Montagekosten. Die Funktionsflächen sind dabei vorzugsweise zur Herstellung einer Schnapp-, Rast- oder Pressverbindung ausgebildet.The use of plastics such as thermoplastics or Elastomers also allow integration of functional surfaces on the contact holder. This allows the assembly assembly optimized be designed, for example, management and storage areas exhibit. This reduces development, material and installation costs. The functional surfaces are preferably for producing a snap, latching or press connection educated.

Zweckmäßigerweise ist ein Montageelement vorgesehen, welches eine automatisierte Handhabung des Federelementes ermöglicht. Dabei kann es sich beispielsweise um eine Montagebohrung handeln, die eine Innenkontur aufweisen kann. Zur besseren Handhabung durch einen Greifer weist das Federelement in einer weiteren Ausführungsform der Erfindung ein gut greifbares, beispielsweise eckiges Profil auf.Conveniently, a mounting element is provided, which allows automated handling of the spring element. This may be, for example, a mounting hole, which may have an inner contour. For better handling by a gripper, the spring element in a another embodiment of the invention, a well-tangible, for example, square profile.
