Definitions

  • the invention relates to a relay comprising a base, an electromagnet arranged on the base with at least one winding and with two pole elements arranged on opposite sides thereof, a permanent magnet extending in its longitudinal direction between the pole elements and outside the electromagnet, and a pivotable about a hinge axis
  • An armature having two armature arms extending in opposite directions away from the hinge axis, of which either a first can be applied to a first one of the pole elements or a second one to a second one of the pole elements.
  • the invention is therefore an object of the invention to improve a relay of the generic type such that this shows an optimal switching behavior.
  • the permanent magnet is magnetized transversely to its longitudinal direction such that this lying on opposite sides Magnetpolate and the pole elements facing end portions having the same magnetization and that the armature is held in electroless electromagnet either with the first anchor arm in a voltage applied to a first end of the end portions end position or with the second anchor arm in a voltage applied to a second of the end portions end position.
  • the advantage of the solution according to the invention is that due to the particular magnetization of the permanent magnet transverse to its longitudinal direction both end regions of the permanent magnet on which the armature can be applied, the same magnetization, that is a magnetization with the same course of the field lines in the end regions, which ensures a higher holding force and thus a more stable definition of the end positions.
  • abutment of the respective anchor arm at the respective end region or pole element is understood to mean a position in which an air gap between the respective armature arm and the end region or pole element is minimal while in the non-applied anchor arm a maximum air gap to the respective end region or pole element having.
  • the air gap is as small as possible when the respective armature arm abuts against the corresponding end region or pole element, that is, as close as possible to zero.
  • a structurally particularly expedient solution provides that the permanent magnet has an approximately parallel to its longitudinal direction extending flat side, which forms the magnetic pole side facing the armature.
  • a particularly advantageous embodiment of a relay according to the invention provides that the permanent magnet is plate-shaped and forms with opposite flat sides Magnetpolnch.
  • the extent in a direction transverse to the longitudinal direction transverse direction may be larger or smaller than in the longitudinal direction.
  • a structurally favorable solution provides that the extent in the transverse direction is smaller than in the longitudinal direction.
  • the magnet pole side facing the armature prefferably has magnetic pole faces facing the respective armature arms in the region of the end regions of the permanent magnet.
  • a particularly large holding force is obtainable when the armature arms in each case in the end region abutting against the respective end region abut flatly with their pole contact surface against the respective magnetic pole surface.
  • a particularly space-saving and structurally favorable solution provides that the electromagnet is arranged on a side facing away from the armature of the permanent magnet.
  • Such a pivotable support on the permanent magnet can be particularly easily realized that the armature rests on this side facing the permanent magnet.
  • a pivotable support of the armature can be realized in a particularly simple manner in that the articulation axis is formed by two joint surfaces, one of which is arranged on the permanent magnet and one on the armature.
  • the hinge axis is defined by at least one curved in at least one direction first joint surface, which cooperates with a second articular surface.
  • the first joint surface could, for example, be arranged on the permanent magnet and the second joint surface on the anchor.
  • the armature is tiltably mounted about a tilt axis extending transversely to the hinge axis and thus has an additional possibility to adapt to outer specifications, for example, not aligned with the hinge axis pole faces or magnetic pole or contact elements during its pivoting movement.
  • the tilting axis is formed by a curvature of the first joint surface in a further direction.
  • a structurally simple embodiment provides that the first articular surface is curved approximately like a spherical cap.
  • Kippbegrenzungsetti are arranged in the further direction on opposite sides of the first joint surface, so that it is possible to limit the tilting movement relative to the pivoting movement with respect to the intended angle.
  • a structurally particularly advantageous solution provides that the armature is associated with a movable by a first action possibility on the part of the armature contact spring, which extends with one arm arm associated spring arm to each at least one actuation area that at least one first contact element is provided on which acts on the contact spring by means of one of the actuating portions and that at least one arranged on the base second contact element is provided, on which the first contact element in the contact-making position of the respective anchor arm can be applied by means of a contact force generated by deformation of the contact spring.
  • the respective anchor arm has a support region facing the respective spring arm for acting on a region of action of the spring arm, if the spring arm in the contact-releasing position of the anchor arm extends with the action region at a distance from the support region and if at least in a contact-making end position the armature arm of the anchor arm by acting on the support region on the area of action of the spring arm has a further possibility of action on the contact spring, which acts in the sense of amplifying the contact force generated by the contact spring.
  • This reinforcement of the spring force, by additional action of the anchor arm with the support region on the impact area has the advantage that the resulting higher contact force from the anchor must be taken only when the anchor arm is already relatively far from the contact-releasing position in the direction of its contact-making end position has moved.
  • the counterforce to be absorbed by the armature and the contact force is dependent on how large the air gap between the armature and the armature attracting pole face of the electromagnet.
  • the support region is arranged on the respective anchor arm in such a way that the area of action of the spring arm can be acted upon after a first contact of the contact elements and before reaching the contact-making end position of the armature.
  • the contact force and thus absorbed by the anchor counterforce is low, and the contact between the section area and the impact area only after a further deformation of the spring arm occurs, thereby resulting larger contact forces and thus larger opposing forces only when a very small air gap still exists between the armature and the attracting pole face of the electromagnet and thus the attraction of the electromagnet is already so great that it can absorb the counterforce corresponding to the larger contact force.
  • the support region has at least one support point with which the support region acts on an action point of the action region on the spring arm.
  • the contact force can be increased in a structurally particularly simple manner.
  • a particularly favorable solution provides that cooperate at the support point and the point of action of the anchor arm and the spring arm such that a spring action of the spring arm is limited to a lying between the point of action and the actuating portion of the spring arm.
  • the inventive concept for increasing the contact force can be realized particularly favorable if the support region has a plurality of support points, which act on a plurality of action points, so that there is a variety of other action options with which the contact force can be adapted to the force relationships at the anchor.
  • consecutively acting on impact points support points they are arranged so that the successively cooperating support points and action points cause an ever-increasing contact force.
  • the support points act on the corresponding points of action only after contact with the contact elements, so that the opposing forces generated by the increased contact forces on the armature does not hinder the movement of the armature in the contact end position, since in these positions from the electromagnet to the armature acting forces are sufficiently large.
  • the supporting points and action points can be formed as successive surface areas, which complement each other to an ever-increasing interaction surface.
  • a structurally simple realizable embodiment provides that the support area or area of action are step-shaped and step edges thereof form the support points or points of action.
  • either the spring arm or armature arm or both elements would be provided which engage behind the armature arm or the spring arm or each other and rest against the armature arm or against one another during the interaction of the support area and the action area on the spring arm.
  • the solution according to the invention can be realized in a structurally particularly simple manner if the spring arm of the contact spring is arranged on a side of the respective armature arm facing the respective second contact element.
  • the support region and the action region can be arranged and formed in a suitable manner on the side of the respective armature arm facing the spring arm and the side of the respective contact arm facing the respective armature arm.
  • the contact spring on a side of the armature facing the electromagnet.
  • the contact spring is arranged on a side opposite the electromagnet side of the armature.
  • the actuating portion is coupled via a holding element to the armature, which in particular such a relative movement of the spring arm relative to the armature arm allows the support area and the action area to abut one another or be spaced apart from one another.

  21. Relais selon la revendication 20, caractérisé en ce que le bras d'induit (40) et le bras de ressort (90) coopèrent au niveau de l'emplacement de soutien (114, 116) et de l'emplacement d'action (134, 136), de telle façon qu'un effet du bras de ressort (90) est sensiblement restreint à un tronçon du bras de ressort (90) situé entre l'emplacement d'action (134, 136) et la zone d'actionnement (104).
  22. Relais selon la revendication 20 ou 21, caractérisé en ce que la zone de soutien (112) comprend plusieurs emplacements de soutien (114, 116) qui agissent sur plusieurs emplacements d'action (134, 136).
  23. Relais selon la revendication 22, caractérisé en ce que lors d'un mouvement du bras d'induit respectif (40) depuis la position finale de libération de contact jusque dans la position finale d'établissement de contact, lesdits plusieurs emplacements de soutien (114, 116) agissent les uns après les autres sur les emplacements d'action correspondants (134, 136).
  24. Relais selon la revendication 23, caractérisé en ce que les emplacements de soutien (114, 116) et les emplacements d'action (134, 136) qui coopèrent les uns après les autres ont pour effet une force de contact (130) qui devient de plus en plus forte.
