Description

Die Erfindung betrifft eine Kontaktbrückenhalterung nach dem Oberbegriff des Anspruches 1. Sie findet Anwendung in elektrischen Schaltgeräten, insbesondere in häufig schaltenden Schaltgeräten, wie Schützen.The invention relates to a contact bridge holder according to the preamble of Claim 1. It is used in electrical switching devices, in particular in switching devices that switch frequently, such as contactors.

Es ist allgemein bekannt, daß Kontaktbrückenhalterungen in häufig schaltenden Schaltgeräten sowohl erheblichen thermischen als auch hohen mechanischen Belastungen ausgesetzt sind. Aus der Druckschrift DE 30 30 702 C2 ist eine Kontaktbrückenhalterung für ein elektromagnetisches Schütz bekannt. Diese besteht aus einem Kontaktbrückenträger aus thermoplastischem Material und weist fensterartige Ausbrüche zur Aufnahme von federnd gelagerten Kontaktbrücken auf. In den Ausbrüchen sind rahmenartige Auskleidungen aus duroplastischem Material angeordnet. Der Kontaktbrückenträger ist hinsichtlich seiner äußeren Abmessungen weitgehend form- und maßstabil und weist gute Gleiteigenschaften aufgrund seines Werkstoffes auf. In denjenigen Bereichen, in denen er besonderen thermischen Belastungen durch die insbesondere bei Kontaktöffnung erhitzten Kontaktbrücken ausgesetzt ist, werden diese Belastungen von den genannten Auskleidungen aus duroplastischem Material soweit aufgefangen, daß Verformungen des thermoplastischen Kontaktbrückenträgers weitgehend vermieden werden. Die rahmenartigen Auskleidungen können entweder in die Fenster des Kontaktbrückenträgers eingeschnappt oder von diesem teilweise umverspritzt werden. Der technologische Aufwand zur Herstellung einer derartigen Kontaktbrückenhalterung ist allerdings zu aufwendig. It is common knowledge that contact bridge mounts are used in frequently switching Switchgear both significant thermal and high mechanical Are exposed to loads. From document DE 30 30 702 C2 is one Contact bridge holder for an electromagnetic contactor known. This consists of a contact bridge carrier made of thermoplastic material and has window-like cutouts to accommodate spring-loaded contact bridges on. In the cutouts are frame-like linings made of thermosetting Material arranged. The contact bridge support is regarding its outer dimensions largely stable in shape and size and has good Sliding properties due to its material. In those areas in which he has special thermal loads due to in particular Contact opening is exposed to heated contact bridges, these loads as far as the above-mentioned linings made of thermosetting material caught that deformation of the thermoplastic contact bridge carrier largely avoided. The frame-like linings can either snapped into the windows of the contact bridge support or from this can be partially overmoulded. The technological effort to manufacture such a contact bridge holder is too expensive.

Der Erfindung liegt daher die Aufgabe zugrunde, eine sowohl mechanisch als auch thermisch belastbare Kontaktbrückenhalterung anzugeben, die einen geringeren Herstellungsaufwand erfordert.The invention is therefore based on the object, both mechanically and to also specify thermally resilient contact bridge holder, the one requires less manufacturing effort.

Ausgehend von einer Kontaktbrückenhalterung der eingangs genannten Art wird die Aufgabe erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Durch die hitzebeständigen flächigen Zwischenelemente, die zwischen den der zugehörigen Festkontakten zugewandten Seite jeder Kontaktbrücke und den zugehörigen Anlagebereichen der fensterartigen Ausbrüche des Kontaktbrückenträgers wird in technologisch einfacher Weise ein Anbacken, Anschmelzen oder Verschweißen zwischen den erhitzen, in ihre Offenstellung bewegten Kontaktbrücken und dem Kontaktbrückenträger sowie eine Verformung des Kontaktbrückenträgers in diesen Bereichen verhindert. Sollte das Schaltgerät mit gegen hohe Fehlerströme schützenden elektromagnetischen Schnellauslösern versehen sein, so wird außerdem mit der erfindungsgemäßen Kontaktbrückenhalterung ein Anbacken der öffnenden Schlagstößel der Schnellauslöser an die Kontaktbrücken wirksam verhindert.Starting from a contact bridge holder of the type mentioned the task according to the invention by the characterizing features of Claim 1 solved. Due to the heat-resistant flat intermediate elements, that between the side of the associated fixed contacts facing each Contact bridge and the associated areas of the window-like breakouts the contact bridge carrier is a technologically simple Baking, melting or welding between the heat in your Open position moving contact bridges and the contact bridge carrier as well prevents deformation of the contact bridge support in these areas. If the switchgear is equipped with electromagnetic protection against high residual currents Fast triggers are provided, so will also with the invention Contact bridge holder a baking of the opening plunger the quick release on the contact bridges effectively prevented.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen. Als Zwischenelemente können Beschichtungen auf der Kontaktbrücke und/oder den zugehörigen Anlagebereichen des Kontaktbrückenträgers dienen. Eine weitere Ausführungsart des Zwischenelementes ist eine im entsprechenden Bereich der fensterartigen Ausbrüche gelagertes Plättchen, das in vorteilhafter Ausbildung mit einer hitzebeständigen Beschichtung versehen sein kann. Mit derartigen Plättchen kann das Schaltgerät an unterschiedliche Hitzebelastungen angepaßt werden. Als Zwischenelement bzw. Beschichtung sind mehrere Materialien geeignet, u.a. PVD -(physical vapor deposition)-Hartstoffschichten, wie z.B. aus Titan-, Chrom-, Titan-Kohlenstoff- oder Titan-Aluminium-Nitrid. Further advantageous embodiments of the invention are the subclaims refer to. Coatings on the contact bridge can be used as intermediate elements and / or the associated contact areas of the contact bridge support to serve. Another embodiment of the intermediate element is one in the corresponding Area of the window-like outbreaks stored platelet, which in advantageous training be provided with a heat-resistant coating can. With such platelets, the switching device can withstand different heat loads be adjusted. As an intermediate element or coating suitable for several materials, including PVD (physical vapor deposition) hard layers, such as. made of titanium, chrome, titanium-carbon or titanium-aluminum nitride.
