Definitions

  • the invention relates to an electromagnetic flap armature relay with one or more changeover contacts.
  • the invention has for its object to increase the contact stroke of a hinged armature relay more than ten times because in switching technology, for safety reasons, a greater contact spacing is now required in cases in which currents with a higher voltage are to be switched.
  • the invention is also based on the object of having the hinged armature switch with as little bounce as possible, in order thereby to increase the service life of the moving parts of the relay.
  • each center contact consists of the combination of a fixed contact carrier with a pivotably mounted contact lever, an extension spring extending approximately in the direction of the contact plane on the one hand at the end of the contact carrier facing away from the contact and on the other hand in the vicinity of the double contact rivet is attached to the contact lever, the two-sided mounting of the contact lever with respect to the possible tension spring effect on the contact carrier is applied so that the means Contact shows either a reset or a snap behavior, while to influence the position of the changeover contact, the action of an anchor-operated, directly on the tension spring or the contact lever pushing or pulling plunger takes place.
  • the folding armature relay equipped according to the invention offers the possibility of achieving an increased contact distance by appropriately selecting the lever ratios, although the contact force is not reduced. Since the tension spring returning the contact lever to the rest position extends approximately in the direction of the contact plane, its space requirement is negligibly small and does not lead to an increase in the structural dimensions of the folding armature relay compared to a conventional one. It is only necessary to increase the distance between the fixed contacts in accordance with the electrical conditions.
  • the contact lever carrying the double contact rivet is supported on both sides in cutting edge bearings and has a central recess, on both sides of which lateral projections extend with edges.
  • the plunger presses on the part of the tension spring facing away from the bearing of the lever and lying outside the lever.
  • the hinged armature relay equipped according to the invention therefore allows, by appropriate selection of the lever ratios, i.e. both the length of the contact lever carrying the double contact rivet, the distance between the bearing of this contact lever and the direction of the tensile force of the tension spring and the point of application thereof on the contact lever as well as the position of the Point of contact of the plunger on the tension spring itself to achieve a switching behavior of the relay that is adapted to the respective switching conditions.
  • the double contact rivet In the rest position, the double contact rivet is always in the one end position of a snap switch, while it is pushed out of this snap end position by the anchor-operated plunger, but is not moved beyond the middle position, for example, from which it could snap into the other end position, so that it always snaps back into the rest position when the hinged anchor falls off.
  • the desired low-bounce behavior of the armature of the hinged armature relay according to the invention is brought about by the fact that the flange of the excitation coil lying on the fastening leg of the yoke consists of an energy-consuming material, for example a suitable plastic, and a break through of the yoke without contact, the damping of the bruises sloping anchor serving, a stop for the approach across the yoke anchor leg approach.
  • the flange arranged on the flange, penetrating through the yoke approach forms a stop for the armature leg extending in the longitudinal direction of the excitation coil, which by de-energizing the relay the tension of the contact springs consumes the kinetic energy of the armature upon impact and, at the same time, prevents a magnetic shunt resulting from contact of the armature leg with the yoke takes place, and the approach is molded on without difficulty in the manufacture of the flange.
  • the assembly also does not require any additional measures, and there is also the possibility of shortening the approach in adaptation to a required anchor stroke in a simple manner by removal, which can be done when using a thermoplastic material, for example by exposure to heat.
  • the flange arranged at the free end of the excitation coil consists of an energy-consuming material, for example plastic, and at least one stop, which serves to dampen the bruise of the attracting armature and protrudes slightly towards the coil core, for the transverse has protrusion forming the armature arm directed towards the coil core o
  • Anchor bruises are to be dampened to a satisfactory extent, it is only necessary to form a projection parallel to the coil axis on the flange arranged at the free end of the excitation coil, which protrudes in length by a small amount, and on the excitation of the relay the armature arm, which is directed transversely to the excitation coil, comes into contact, whereby a satisfactory damping of the armature bruises is also achieved.
  • the projection is expediently arranged directly below the coil core; However, several projections can also be arranged, which surround the lower region of the coil core on an arc of a circle.
  • the arrangement of the projection does not require any additional expenditure in terms of manufacture and assembly, since it can be molded on without difficulty during the manufacture of the flange.
  • the contact lever 2 carrying the double contact rivet 1 is supported in the edge bearing 3 on the contact carrier 4.
  • the tension spring 5 is fixed at one end 6 to the contact carrier 4 and at the other end 7 to the contact lever 2, in this case by simply hooking it on.
  • the longitudinal axis 5a of the tension spring 5 lies in the central position of the movable double contact rivet 1 next to the edge bearing 3, so that a considerable return component is still exerted on the contact lever 2 System has been pivoted to the fixed contact 8 (see also Fig. 4).
  • the contact lever 2 contains a central recess 11 through which the tension spring 5 extends.
  • the projections (14, 15) on both sides of the contact carrier sections 12 and 13 are angled, as can be seen in FIG. 1, and the struts 4a and 4b on both sides are bent offset to improve the leverage ratio.
  • the edges 16 and 17 of the lateral, angled projections 14 and 15 engage in the recesses 18 and 19 of the projections 12 and 13 of the carrier 4, which ensures low-friction mounting of the contact lever 2.
  • the yoke 23, 23 'at the point of the bend has an opening 28 which is impressed in the punching path during the manufacture of the yoke, and the flange of the excitation coil 21 which bears against the fastening leg 23' of the yoke has one, the through Refraction 28 freely penetrating pin-shaped projection 29 which ends above the yoke leg 23 and forms a stop for the armature leg 24 when the relay de-energizes and the armature 24, 25 is brought into the position shown in FIG. 6 under the action of the tension of the contact springs.
  • a flange 30 which is arranged parallel to the axis of the excitation coil 21 and which protrudes slightly from the coil core 22 is arranged on the flange 27 arranged at the free end of the excitation coil 21, so that at Excitation of the relay of the anchor leg 1 25 comes into contact with the neck 30 and dampens the anchor bruises.
  • the approach 30 can be molded in one and the same operation without difficulty in the manufacture of the flange 27.
