Definitions

  • the invention relates to a switching device according to the preamble of claim 1.
  • Fig. 2 shows a schematic diagram of a switching device such as a DC high-speed switch the state of the art.
  • the switching device comprises a first one and second rigid connector 5, 4 for connection a circuit to be switched and a movable contact lever 1, which is rotatably mounted about an axis of rotation 6.
  • the contact plate 2 is open attached to the movable contact lever 1, which has a movable Connection such as a flex band 3 with the second connector 4 is electrically connected.
  • Flexbands 3 are also current bolts, friction contacts or the like. as. Connecting devices between the contact lever and the second connector 4 possible.
  • the contact lever is to be designed so that it following mechanical and electrical requirements met.
  • the contact lever should be one if possible have low mass inertia, thereby a to enable fast switching. Because of a required high current carrying capacity results in a possible high contact lever cross-section and the lowest possible specific Resistance of the contact lever material as electrical Conditions.
  • FR-A-2 461 348 discloses a switching device according to the preamble of claim 1.
  • the switch contact By arranging the switch contact on the lever side the function of the current and heat conduction from the function of the contact guide Cut.
  • the contact lever takes over purely mechanical Management tasks, so that the demands placed on them with regard to the current carrying capacity.
  • the contact lever By the separation of the power line function from the contact guidance function can the contact lever in a lightweight design with low inertia from, for example, electrical non-conductive material.
  • the configuration of the switching device according to the invention allows the use of a relatively long, flexible Flexbands 3, whereby a shape can be realized has a positive impact on the lifespan.
  • the contact plate 2 directly on the as a movable connector serving flex band 3 arranged.
  • the Switching state shown in dash-dot lines runs the Current path only when the switching device is closed the two connecting parts 4 and 5 and the flex band 3.
  • the Function of the contact lever 1 is thus on the contact guide limited and can therefore also be made of non-conductive material getting produced.
  • the shape of the flexible band is preferably such that that a low-wear switching operation enables becomes. This can be done, for example, by a suitable one Curvature guide and attachment to the second connection part 4 can be achieved.
  • a flexible copper band 3 is connected at its lower end to the second connection part 4 in such a way that it is aligned with the first connector 5 is.
  • the copper strip 3 has a pre-curvature, so that Mechanical stresses occurring during the switching process are reduced become.
  • the copper strip also has a slot 8 in which the contact lever 1 is partially fitted.
  • an electrically conductive Contact plate 2 directly on the copper strip 3 or a suitable one Connection bracket soldered.
  • the top of the Copper strip 3 is fitted into a recess in the contact lever 1 and to achieve a massive electrical connection preferably pressure welded.
  • a pre-contact 7 attached to the main contact in operational switching operations before burning protects and thus increases the service life of the main contact.
  • a switching device for switching a electrical connection between two connecting parts disclosed.
