Definitions

  • the invention relates to a relay comprising a base, an electromagnet arranged on the base, an armature with at least one pivotally mounted on the base and movable by means of the electromagnet between a contact-releasing end position and a contact end position armature, a movable means of a first Einstattsdorfkeit part of the armature Contact spring, which extends with at least one spring arm up to at least one actuation region, at least one first contact element, which acts on the contact spring by means of the at least one actuation region, and at least one arranged on the base second contact element, on which the first contact element in the contact-making position the anchor arm can be applied by means of a contact force generated by deformation of the contact spring.
  • the invention is therefore based on the object to obtain the largest possible contact forces with the lowest possible power during energization of the electromagnet.
  • the armature arm has a support region facing the spring arm for acting on a region of action of the spring arm, that the spring arm extends in the contact-releasing position of the anchor arm with the action area at a distance from the support area and that at least in a contact-making end position of the anchor arm of the anchor arm by acting on the support region on the action region 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 the additional action of the armature arm with the support area on the impact area has the advantage that the resulting higher contact force from the armature must be absorbed 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 counteracted by the anchor and the contact force corresponding counterforce depends on how large the air gap between the armature and the armature attracting pole face of the Electromagnet is. The smaller this air gap, the greater counter-forces can absorb the anchor without its movement is disturbed to reach the contact-making end position of the respective anchor arm or hindered by the opposing force.
  • the support region is arranged on the armature 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 small and the contact between the support area and the impact area only after a further deformation of the spring arm, the resulting larger contact forces and thus larger opposing forces occur only then, if between the armature and this attracting pole face of the electromagnet, a very small air gap still exists and thus the attraction of the electromagnet is already so large that it can accommodate the larger contact force corresponding counterforce.
  • 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. This can be increased in a simple manner caused by the spring action contact force.
  • the concept according to the invention for increasing the contact force can be realized in a particularly favorable manner when the support region has a plurality of support points which act on a plurality of action points, thereby providing a multiplicity of further action possibilities with which the contact force can be adapted to the force relationships at the armature.
  • 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 easily realizable embodiment provides that the support area or the impact area are step-shaped and form step edges thereof the support points or points of action.
  • the support region and the action region could cooperate in such a way that they have an extension in the direction parallel to the joint axis, which improve a tilting stability of the actuation region.
  • this can be realized in that the support area and the action area in the direction of the tilt axis cooperate maximally substantially linear.
  • the supporting area and the area of action cooperate in a substantially point-like manner, since in this case the spring arm has the possibility of optimally adapting to the reaction forces arising when the contact elements abut one another.
  • the support region and the action region are preferably made for the support region and the action region to have an extension in the direction parallel to the joint axis which is smaller than one quarter of a distance of the first contact elements in the direction of the joint axis.
  • the contact spring on a side facing away from the second contact element of the at least one anchor arm.
  • the realization of the support area and the action area is complicated because they would have to cooperate in such a way that the spring element is acted upon in the direction of increasing the contact force.
  • either the spring arm or armature arm or both elements would be provided which engage behind the anchor arm or the spring arm or each other and bear against the spring arm, armature arm or against each other during the interaction of the support area and the action area.
  • 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 armature arm facing the respective second contact element.
  • the support region and the exposure region can be arranged and formed in a suitable manner on the side of the anchor arm facing the spring arm and the arm side facing the armature arm.
  • the contact spring is to be arranged so that it extends outside of a Polstrom constitutional the armature.
  • the contact spring in the region of the Polstrom schemes has a recess, so that the formation of the contact spring and the positioning of the Polstrom matters at the anchor are independent of each other.
  • contact spring is disposed on a side opposite the electromagnet side of the armature.
  • a contact surface of the armature abutting the electromagnet in the contacting end position is arranged on a side of a joint opposite the contact elements for the pivotable mounting of the armature.
  • a particularly favorable solution provides to form the electromagnet as two magnetic poles having magnets, each of which cooperates with an anchor arm of a rocker designed as a rocker.
  • the actuation area is coupled to the armature via a retaining element which in particular permits such a relative movement of the spring arm relative to the armature arm. that the support area and the action area abut each other or can be at a distance from each other.
  • such a holding element is designed as a movement of the spring arm relative to the anchor permitting stop element.
  • a first embodiment of a relay according to the invention shown as a whole in Fig. 1 and 2, comprises a base 10, on which a designated as a whole by 12 electromagnet is held, which has a winding 14, one of the winding substantially enclosed winding core having a pole body 16 and a return body 18 which is connected to the winding core 16 and with a first leg 20 via an end face 22 of the winding 14 and with a transverse to the first leg 20 extending second leg 24th extends transversely to the end face 22 of the winding 14, wherein on this second leg 24 by means of a joint 26, an armature 30 is mounted about a hinge axis 28 which extends with an anchor arm 31 via an end face 22 opposite end face 32 of the winding 14, via which the pole body 16 projects with a pole face 34.
  • the armature 30 in turn is acted upon by a spring 40 in the direction of a contact-releasing end position shown in FIG. 1, wherein the spring 40 is arranged, for example, on a side of the second leg 24 opposite the winding 14 and, on the one hand, fixed to the second leg 24 connected bearing point 42 and on the other hand acts on a lever arm 44, which extends on a side opposite the armature 30 side of the hinge axis 28 and extending from the armature 30.

  • This connection between the armature 30 and the contact spring 50 forms a first action possibility for moving the contact spring 50 by means of the armature 30th
  • the contact spring 50 extends with a spring arm 60 between the fixing region 56 and the second end 54, to which an actuating region 62 of the contact spring connects, to which a first contact element 70 is held, which is used to make an electrical contact can be moved in the direction of a second contact element 72 and, as shown in Fig. 2, in the contact-making end position, in contact with this can be brought.
  • the second contact element 72 sits on a base 74, which in turn is likewise held on the base 10.
  • the spring arm 60 has an engagement region 80, which extends in the contact-releasing end position of the armature 30 at a distance from a support region 82 of the anchor arm 31, so that the support region 82 can not act on the action region 80.
  • This support region 82 includes, as shown again in FIGS. 3 and 4 for clarity, three support edges 84, 86, 88, which are arranged by the extending in the contact-free end position spring arm 60, namely from the impact area 80 thereof, with increasing distance, wherein the first support edge 84 is formed by a relative to the fixing surface 58 recessed first surface 94, which at the first support edge 84 in a second surface 96, which is even stronger relative to the fixing surface 58th and the impact area 80 is reset. Furthermore, the second surface 96 extends to the second support edge 86 and merges therewith into a third surface 98, which is set back even further in relation to the fixing surface 58 and also to the action region 80 in the contact-releasing position. This third surface 98 then in turn merges into a fourth surface 100 at the third support edge 88, wherein the fourth surface 100 has the greatest distance from the fixing surface 58 and the exposure region 80 in the non-contact end position of the armature 30.
  • Fig. 3 also has the fixing portion 56 of the contact spring 50 is still a recess 102 through which passes the transition of the armature 30 from the contact-releasing end position in the contact end position of the pole body 16 with the pole face 34, so that the anchor arm 31st of the armature 30 can come to rest with a Polstrom constitutional 104 on the pole face 34.
  • the contact spring 50 is still provided with a holding element 106 in the region of the second end 54, which preferably has an upper side 108 facing away from the electromagnet 12 of the armature 30 engages and then comes to rest on the upper side 108 when the spring arm 60 would move too far away from the armature 30, in particular the support region 82, due to adhesive contact elements 70, 72.
  • the holding member 106 is formed so that it is then applied to the top 108 straight when the spring arm 60 is in the contact-releasing end position of the armature 30 in its undeformed position and the impact area 80 thereof extends at a distance from the support portion 82 of the armature 30.
  • the armature 30 is attracted by the pole body 16 and pivots against the force of the spring 40 about the hinge axis 28 of the joint 26 so that the Polstrom constitutional 104 moves in the direction of the pole face 34.
  • This contact force 110 increases with increasing deformation of the spring arm 60 and increasing movement of the action region 80 in the direction of the support region 82.
  • the action area 80 comes into abutment with an action point 114 at the support edge 84, while the action area 80 does not yet bear against the other support edges 86 and 88.
  • This additional support of the spring arm 60 in the region of the action point 114 on the support edge 84 on the armature 30 is a second possibility of action of the anchor arm 31 on the spring arm 60 and has the consequence that the contact force generated by the spring arm 110 110 now of the deformation of the spring arm 60 between the action point 114 and the actuating portion 62 is dependent, wherein this portion has a length L1 which is smaller than a length L0 of the spring arm 60th
  • a further deformation of the spring arm 60, in particular of the section L1 thereof, results in that the action region 80 comes into abutment with and is supported by a second action point 116 on the second support edge 86, so that a third possibility of action of the armature arm 31 on the spring arm 60 and the still free resilient portion of the spring arm 60 is only the portion between the action point 116 and the actuating portion 62 whose length L2 is smaller than the length L1.
  • this portion of the spring arm 60 behaves even stiffer than the portion having the length L1 and the contact force 110 generated by deformation thereof becomes even larger.
  • a further increase in the contact force 110 can still be achieved if the further deformation of the spring arm 60 causes the impact area 80 with the action point 118 at the third support edge 88 comes to rest, and by a fourth possibility of action thus remaining, free-floating Section of the spring arm 60 has the length L3, which is even shorter than the length L2, so that the contact force 110 is even greater.
  • the distance between the supporting edge 88 and the action region 80 of the spring arm 60 is selected so that the impact area 80 at the point of action 118 only shortly before reaching the contact position of the armature 30 comes to rest, so that in the contact-making end position of the armature 30, in which this rests with the Polstrom constitutional 104 on the pole face 34, the maximum contact force 110 is available to press the contact elements 70 and 72 against each other.
  • the advantage of the inventive increase in the contact force 110 by successive application of the action region 80 on the support edges 84, 86 and 88 has the advantage that the contact force 110 can be successively increased, wherein the successive increase in the contact force 110 even with increasingly smaller distance between the Pole surface 34 and the Polstromamide 104 takes place and thus uses the increasing magnetic force with decreasing air gap.
  • the armature 30 must also absorb the opposing forces arising from the increasing contact forces 110 only when the air gap between the pole face 34 and the Polstrom constitutional 104 is small enough and thus acting on the armature 30 holding force of the electromagnet 12 is sufficiently large, so that they can safely overcome the opposing forces.
