Definitions

  • the invention relates to an electrical switching device according to the preamble of claim 1.
  • document US 4 039 985 A describes an electrical switching device in the form of a reed relay, in which a switching element made of magnetic material between two mating contact elements of non-magnetic material is arranged. On the side next to the mating contact elements, a holding magnet is attached in each case. Another, movably mounted magnet causes by its movement, for example, a move towards a holding magnet or away from a holding magnet, an increased attraction of the switching element to one side. The switching element is thus to the mating contact element, which is on the side of stronger magnetic field, moved and held by the holding magnet there.
  • the DE 23 04 775 A1 shows a switchable by magnetic energy switch.
  • two permanent magnets with the surfaces of the unlike poles are arranged at a distance opposite. Between the two magnets is a contact pair, which can be closed by a freely movable anchor.
  • a contact pair which can be closed by a freely movable anchor.
  • a wire winding By a wire winding, a magnetic field and thus a polarization of the armature is effected.
  • the armature is moved towards the one or other permanent magnet and a contact between the contact pair is closed.
  • the switching process can also be triggered by a common displacement of the two permanent magnets perpendicular to the plane of the contact pairs.
  • a switching device of this kind is in the DE 101 03 814 A1 described.
  • 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 selectively 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 lateral switching movement of a switching element is achieved by means of external mechanical force by plunger, which thrust laterally against the switching element and move it. Due to the lateral pivotal movement, which executes the switching element and the linear thrusting movements of the plunger present on either side of the switching element arise in the contact region of the plunger and the switching element sliding movements, which lead to abrasion due to the resulting friction.
  • the switching device has a closed switching space, the risk of a contact failure by the abrasion generated by the friction is particularly large because the abrasion remains in the control room. But even with an open switch room there is a risk that the abrasion reaches between the contact surfaces and affects the electrical contact.
  • the plunger can have negative effects on the RF behavior.
  • 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 an increase in the distance between it and the switching element in both aforementioned switching cases.
  • 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 respectively 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.
  • two magnets are arranged opposite one another on both sides of the switching element.
  • a plurality of magnets in particular in each case a Verstellmagnet pair, arranged on both sides of the switching element, wherein the opposing magnets of each pair must be of the same polarity.
  • 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.
  • 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 Polanowski arm or Polumscados generate attractive and repulsive magnetic forces, with two electromagnets can simultaneously generate the respective drive movement in a gain or doubling the driving forces.
  • the drawing shows a plurality of switching devices, designated in their entirety by 1, whose electrically interconnectable line sections form the longitudinal sections of an electrical line 2 and each have a switch 3 with a switching element 4 which can be moved back and forth transversely to the electrical line 2 and which serves to to open or close the line 2.
