Definitions

  • the object of the present invention privilege patent is an innovative magnetic mechanical switching key, belonging to the field of basic electrical components, used more precisely to make the electrical switching, that is, to effect the change of direction of the electric current , to block or allow the passage of electrical current.
  • Said key comprises a fixed structure that bears the fixed electrical contacts and a mobile structure that bears mobile electrical contacts.
  • the configuration of the mechanism regarding the number of contacts can vary depending on the switching required.
  • the fixed part contacts are distributed in two sets of opposing contacts.
  • the mobile element contains an equal number of sets of electrical contacts and also magnetic elements, which under the action of magnetic or electromagnetic forces external to the switch will move the mobile element and consequently move the set of moving contacts, then performing the switching.
  • Fast mechanical drives can be made possible by electromagnetic coupling as shown in relays. These elements can switch at relatively high rates, for example, 60 and 50 Hz.
  • the "reed bulb” works through the phenomenon of magnetic induction in a ferromagnetic element, just like relays.
  • the induction can be performed by a magnetic element, it does not necessarily have to be performed by an electromagnetic element and, with this, it manages to be more agile than the relays.
  • its activation is delicate due to its own operating principle.
  • the swing switching blades inside the ampoule can undergo permanent torsions and deformations depending on the magnetic field to which they are subjected.
  • this patent was designed to obtain an electrical device with the fewest possible parts, conveniently configured and arranged to allow the magneto mechanical switch to perform its functions with efficiency and versatility, without the inconveniences already mentioned.
  • the present device develops the possibility of switching at high frequencies by exclusively magnetic couplings between permanent magnets. [012] This makes it possible for the frequency of operation of the switch to be regulated by the speed of interaction between the magnetic poles of the switch and what comes to drive it. In addition, the bearing system and the mobile part free of cables or any other conductive component that permanently attaches the mobile part to the fixed part, guarantee a precise, robust and agile movement.

  • Said mobile structure (7) has a oscillating rotational movement around the axis (6), similar to a seesaw, commanded by the interaction of external magnetic forces with the permanent magnets (9) and (9A).

  • the mobile structure (7) together with the electrical contacts (1 1), (1 1 A), (1 1 B) and (1 1 C) and the permanent magnets (9) and (9A), make up the mobile part (15) of the device.

  • FIG. 6 shows the electrical schematic of a possible configuration of the magneto mechanical switch, where there are two inputs (E1) and (E2) and two outputs for each input (S1), (S2), (S3) and (S4).
  • the Input (E1) corresponds to the electrical contacts (3) and (3D), electrically connected; Input (E2), corresponds to electrical contacts (3B) and (BF), electrically connected; Output (S1), corresponds to electrical contact (3A), Output (S2), corresponds to electrical contact (3E), Output (S3), corresponds to electrical contact (3C) and Output (S4) corresponds to contact electric (3G).
  • the permanent magnets (9) and (9A) can be arranged with fields in the same or opposite directions. In this way, the operation of the key occurs when one of the magnets or both act in such a way as to force the rotation of the mobile structure (7) around the axis (6).
  • FIG. 9 which represents the operating dynamics of the elements described in FIG. 10, we have a contact condition (17) in which the electrical contact (3D), is being connected to the electrical contact (3E) through the electrical contact

Abstract

La présente demande de brevet concerne une clé de commutation dont la manoeuvre est effectuée par l'intermédiaire de forces magnétiques, relevant du domaine des composants électriques de base. Les clés magnétiques connues de l'état de la technique ne peuvent pas être utilisées dans des fréquences plus hautes, notamment dans des circuits de puissance, du fait de la limitation de leur propre principe électromagnétique. Afin de résoudre ce problème, l'objet de la présente demande de brevet a été mis au point, constitué à partir d'une structure (2) rigide de géométrie essentiellement prismatique rectangulaire, de type boîtier, présentant une pluralité de contacts électriques fixes (3), (3A), (3B), (3C), (3D), (3E), (3F) et (3G) en quantité préférentielle de quatre, mais pouvant varier selon le projet, opposés à des contacts électriques mobiles (11), (11A), (11B) et (11C), commandée par interaction de forces magnétiques externes avec les aimants permanents (9) et (9A).
