Definitions

  • the invention relates to a relay having at least one, in each case the circuit between a first and a second relay contact closing or interrupting contact spring whose one end is conductively connected to the first relay contact and closed via the other, free end of the circuit in a first relay position of the contact spring or in a second relay position of the contact spring is interrupted, with a magnetic drive for deflecting the at least one contact spring in the respective relay position, wherein the magnetic drive comprises a umpolbare magnetic coil and a permanent magnet having an armature, which on the magnetic coil is held pivotably between two switching positions, and with a displaceable in the deflection of the at least one contact spring slide, which is coupled in motion with the armature and has two drivers, between which the free end of the at least one contact spring is arranged.
  • Such a relay is for example by the DE 101 62 585 C1 known.
  • the circuit between two electrical relay contacts by means of two parallel contact springs is closed or interrupted.
  • the contact springs are connected via a slide displaceably guided in the relay housing in conjunction with a permanent magnet of an H-armature, which is held pivotably on two yoke legs of a magnetic coil.
  • the movement coupling of the slide with the armature by means of an arm provided on the arm, which engages with its spherical free end in a bearing opening of the slide, which engages behind the contact springs in and opposite to the deflection.
  • This object is achieved in that is for the motion coupling of the armature at least two spaced apart in the direction of its pivot axis coupling points with the slider in engagement.
  • the armature engages via at least one 2-point bearing with the slide, which is thereby held in a tilted manner relative to the armature and therefore guided without tilting in the guides of the relay housing.
  • the armature and the slide are coupled in motion with each other via at least one arm of the armature, which extends in the direction of the pivot axis of the armature and on which the at least two spaced-apart coupling points are provided.
  • the armature and the slider are coupled in motion to each other via at least two parallel arms of the armature, which are spaced apart in the direction of the pivot axis of the armature and each forming a coupling point.
  • a plurality of the circuit between the two relay contacts each closing or interrupting parallel contact springs are provided, which are deflected together by the magnetic drive in the respective relay position.
  • the plurality of parallel contact springs may be separate contact springs or a single multiple contact spring having a common attachment end and a plurality of free ends.
  • the one or more parallel contact springs and the arm or arms of the armature are arranged centrally relative to each other or centered.
  • relay 1 comprises two relay contacts 2, 3 and three the circuit between the two relay contacts 2, 3 each closing or interrupting parallel contact springs 4, which are formed as electrically conductive leaf or flat springs (eg made of copper).
  • the one, in Fig. 1 left ends 5 of the contact springs 4 are electrically conductive on the in Fig. 1 fixed upper relay contact 2, while the other, free ends 6 of the contact springs 4 each carry a contact button 7 on its underside and are jointly deflectable by means of a magnetic drive 8 .
  • the contact springs 4 are in their in Fig. 1 shown closed relay position deflected down so that their contact buttons 7 abut respectively on contact buttons 9 of the lower relay contact 3. In the open relay position, the contact springs 4 are deflected upward so that their contact buttons 7 are lifted from the contact buttons 9 of the lower relay contact 3.
  • the three contact springs 4 are connected together at their attachment ends 6 and thus form a triplet spring.
  • the magnetic drive 8 comprises a umpolbare magnetic coil 10 with a magnetic circuit, at the two yoke legs 11, a magnet armature 12 (not shown) with a permanent magnet is pivotally held about the pivot axis A.
  • the permanent magnet is arranged between two armature plates 13 , which rest in each case on the yoke legs 11 in the two switching positions of the armature 12.
  • the magnetic coil 10 and the pivotable between its two switching positions armature 12 form a H-anchor suit.
  • Armature 12 has two parallel to the pivot axis A projecting parallel arms 14a, 14b, which are each formed at their free ends 15a, 15b spherical and spaced from each other in the direction of the pivot axis A.
  • the armature 12 engages with its two projecting arms 14a, 14b, more precisely with its spherical ends 15a, 15b, each in a bearing opening 16 of a slider 17 which in the relay housing in the deflection of the contact spring 5 and parallel to the axis of the solenoid 10 linearly displaceable (double arrow 18 ) is guided.
  • the two bearing openings 16 are each arranged centrally between two contact springs 4.
  • the armature 12 is thus at two in the direction of its pivot axis A spaced-apart coupling points 15a, 15b with the slider 17 for the movement coupling into engagement.
  • the hinged to the slide 17 armature 12 forms an armature rocker for deflecting the contact springs 4 in their open or closed relay position.
  • the slider 17 engages with a lower driver 19, the free ends 6 of the contact springs 4 and engages with an upper driver 20 three spring steel leaf springs 21, which are each secured on top of the free ends 6 of the contact springs 4 and the free ends 6 of the contact springs 4 project.
  • the slider 17 takes with its lower driver 19, the contact springs 4 in the opening direction of the relay 1, ie upwards, and with its upper driver 20 via the leaf springs 21, the contact springs 4 in the closing direction of the relay 1, ie down, with.
  • the free ends 6 of the contact springs 4 are coupled with the slide 17 in the opening direction directly and in the closing direction by means of the leaf springs 21.
  • the contact springs 4 are each formed as a multi-layer leaf spring, the two lower layers each have a laterally projecting from their plane arc section 22 .
  • the magnetic field of the magnetic coil 10 is reversed, whereby the armature 12 is pivoted and the slider 17 is moved.
  • the slider 17 In the in Fig.1 shown closed relay position, the slider 17 is moved downward by the downwardly pivoted arms 14, which are deflected by the leaf springs 21 and the contact springs 4 synchronously down to the contact buttons 7 on the contact buttons 9 of the lower relay contacts 3.
  • the contact pressure of the contact buttons 7 to the contact buttons 9 of the lower Relay contacts 3 is given by the pressure force of the slider 17 compressed leaf springs 21.
  • the leaf springs 21 counteract the deflection of the contact springs 4 in the opening direction, which leads to a reduced-rebound closure of the relay 1.
  • the armature 12 By reversing the magnetic coil 10, the armature 12 is pivoted in the opposite direction and the slider 17 is moved in the opposite direction.
  • the slider 17 In the open relay position, the slider 17 is displaced by the upwardly pivoted arms 14 upwards, whereby the contact springs 4 are taken from the lower drivers 19 of the slider 17 and the contact buttons 7 are lifted synchronously from the contact buttons 9 of the lower relay contacts 3.
  • the slider 17 Due to the 2-point bearing of the armature with the slider 17, the slider 17 is kippfest connected to the armature 12 and therefore guided without tilting in the guides of the relay housing.
  • the two arms 14a, 14b of the armature 12 are each arranged in the parting plane between two contact springs 4.
  • armature 12 ' has a single arm 14' , which has a width B in the direction of the pivot axis A of the armature 12 '. With this width B engages the spherical shaped free end 15 of the arm 14 'in the corresponding bearing opening (not shown) of the slider 17 a.
  • Fig. 4 are exemplified the two lateral ends of the free end 15 as two in the direction of the pivot axis A spaced-apart coupling point 14a, 14b of the armature 12 '. Due to the non-point storage of the armature 12 'with the slider 17, the slider 17 is kippfest connected to the armature 12' and therefore guided without tilting in the guides of the relay housing.
