Definitions

  • the invention relates to an electrical switching device according to the preamble of claim 1.
  • a switching device of this type is described in DE 101 03 814 Al.
  • This switching device is used in particular to switch a power line for a high-frequency attenuator via different damping elements.
  • it has an elongated and preferably flat switching element, which is movable transversely to its longitudinal direction by an adjusting element and is thereby brought with a contact surface at one end either out of contact or in contact with a mating contact surface. In the contact position, the conduction of the electrical current at the contact surfaces is dependent inter alia on the contact surface and the mating contact surface. Impurities or particles can significantly affect the power line, especially if the impurities or particles are made of electrically non-conductive material.
  • Emissivity lines have e.g. several serially arranged four-pole switching devices with input and output side equal and constant characteristic impedance and each adjustable calibrated damping and thus also precise level.
  • the invention has for its object to improve the transverse motion drive for the switching element in an electrical switching device of the type specified. Furthermore, friction processes and, as a result, the risk of damage to the electrical contact due to abrasion should be eliminated or at least reduced. In particular, the formation of abrasion in the vicinity of the contact surfaces should be avoided or at least reduced. In addition, a non-contact transverse movement of the switching element should be possible, preferably in a closed and in particular hermetically sealed or sealed housing. In addition, a simple construction should be created.
  • the invention is based on the finding that in a switching movement drive of the switching element with magnetic forces there is no need for mechanical movement drive contact between the switching element and the adjusting elements and therefore generated at with magnetic forces Switching movements of the switching element no mechanical contact is present and therefore therebetween neither a sliding friction takes place nor a resulting abrasion is generated.
  • the invention is further based on the finding that the effectiveness of the magnetic force of a magnet in dependence on the size of the distance between the magnet and a magnetic force detected by the element is variable and decreases with increasing distance and increases with decreasing distance.
  • the switching element consists at least partially of magnetic material, and the adjusting elements are each formed by at least one magnet.
  • a corresponding switching function is achieved when the opposite other magnet is advanced towards the switching element.
  • the magnetic force acting on the switching element of the non-advanced magnet can be reduced by increasing the distance between it and the switching element.
  • the effectiveness of the magnetic force of the advancing magnet is increased and the switching of the switching element to the associated mating contact element amplified.
  • the switching function can be further improved or simplified if the non-advanced magnet is simultaneously moved away or moved backward by the switching element, which reduces its magnetic force acting on the switching element and therefore the effectiveness of the magnetic force of the advancing magnet is increased. It is therefore advantageous to simultaneously move both opposing magnets in the same transverse direction, which increases the effectiveness of the magnetic force of the Verstellmagnets moving towards the switching element and reduces the effectiveness of moving away from the switching element magnet.
  • Such a movement drive for the magnets can be easily configured in that the magnets are connected to each other by a coupling member or are arranged on a common transversely movable slide.
  • one of the two magnets thus fulfills by its forward movement the switching function, i. the movement of the switching element to the respective mating contact element and the contact holding function on the mating contact element, wherein the effectiveness of the magnet, which is opposite to the mating contact element to be contacted, is reduced or canceled by the travel or return movement.
  • the invention is characterized in each case by a simple configuration, which can be realized in a small construction, because it requires no mechanical connection between the switching element and the magnet. Due to the lack of a mechanical connection, the embodiments according to the invention with respect to the distances between the switching element and the adjusting elements are variable and adaptable, so that they are in simple and advantageous to integrate into existing designs.
  • the embodiments of the invention are also very advantageous in combination with a leaf spring-shaped switching element whose broad sides are facing the respective associated magnet.
  • the switching element may have the dimensions of a thin film, so that the switching element with low movement forces in the direction of the respective opposite mating contact element is movable and durable in contact.
  • the switching element does not need to be moved directly against the respectively associated magnet. Even if a sufficient distance between the switching element and the magnet is present in the contact position, the contact holding function is ensured at a sufficient magnetic force of the magnet.
  • the embodiment of the invention is also particularly suitable for a switching device in which the switching elements are arranged in a preferably sealed shelter of a housing, which eliminates bushings for mechanical adjustment.
  • the adjacent contact ends of the two Switching elements overlapping magnet may be arranged for moving both switching elements, which is mounted transversely movable back and forth. This makes it possible to realize a four-pole switching device with only two magnets in a simple manner.
  • the two magnets are arranged opposite one another on both sides of the switching element.
  • the two magnets of each pair may have a distance from each other, which is preferably about equal to or greater than a central plane of movement of the switching element, as the width of the preferably flat tongue-shaped switching element.
  • a preferably common motion drive to the magnet or pairs of magnets, preferably each with an electric drive motor.
  • an electric drive motor an electromagnet is particularly advantageous, which causes by magnetic forces the desired movement of the respective at least one magnet or a plurality of magnets comprising movement unit.
  • an electromagnet is particularly advantageous, which causes by magnetic forces the desired movement of the respective at least one magnet or a plurality of magnets comprising movement unit.
  • a magnetic drive can also be by a corresponding Pole arrangement or pole switching attractive and repulsive
  • Reinforce or doubling the drive forces can simultaneously generate the respective drive movement.
