Definitions

  • 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.
  • 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.
  • Coatings on the contact bridge can be used as intermediate elements and / or the associated contact areas of the contact bridge support 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.
  • a contactor Contact bridge bracket 2 consists of a contact bridge support 4, the with a window-like cutout 6 for receiving a metallic contact bridge 8 is provided.
  • the contact bridge 8 is between one another Contact bridge 8 and contact bridge support 4 supporting contact spring 10 slidably mounted in the contact bridge support 4.
  • Several of the same kind Contact bridge mounts are through openings 12 of their contact bridge carriers 4 connected to a contact drive, not shown.
  • the intermediate element 28 advantageously consists of a highly cross-linked material, for example made of thermosetting material or glass fiber.
  • the intermediate element 28 can also have a coating evaporated heat-resistant material facing the plant areas 26 Be side of the contact bridge 8.
