Definitions

  • the invention relates to a 2-pole relay for switching two circuits.
  • 1-pole relays for switching a circuit are well known. That's how it is DE 101 62 585 C1 or DE 102 49 697 B3 a 1-pole relay, in which a circuit between two electrical relay contacts by means of two parallel contact springs is closed or interrupted.
  • the contact springs are connected via a displaceable actuating element in conjunction with a permanent magnet of a H-armature, which is pivotally supported on two yoke legs of a magnetic coil. When reversing the magnetic coil pivots the permanent magnet, causing the Actuator is moved. Since the actuating element engages behind the contact springs in their deflection direction, they are thereby deflected out of their closed rest position so that the circuit is interrupted.
  • the free ends of the contact springs are subjected to force in the direction of the closed end position in each case by a leaf spring, which is attached to the respective contact spring and is supported with its free end on the actuating element.
  • GB-A-2 413 703 discloses the preamble of claim 1.
  • a 2-pole relay as disclosed in claim 1, with two 1-pin relay contact devices each have at least one, respectively the circuit between a first and a second relay contact closing or interrupting contact spring, one end of each conductive connected to the first relay contact and via the other, free end of the circuit in a first relay position of the contact spring is closed or interrupted in a second relay position of the contact spring, and with a magnetic drive for synchronous deflection of the contact springs of the two 1-pole relay contact devices in the respective relay position, wherein the two 1-pole relay contact devices are spaced apart in the deflection of their contact springs and the magnetic drive between the two 1-pole relay contact devices is arranged.
  • the solenoid coil (relay coil) is arranged between the contact sets of the two 1-pole relay contact devices and serves for the synchronous switching of the two 1-pole relay contact devices.
  • the 2-pin relay can also be equipped with a power consumption shunt. By placing the drive in the middle of the relay, external influence from strong magnetic fields is less and does not lead to unauthorized changing of the switching state.
  • FIGURE shows a plan view of the inventive 2-pole relay with the cover removed.
  • the 2-pole relay 1 shown in the figure comprises two superposed 1-pole relay contact devices 2 and a common magnetic drive 8 arranged therebetween.
  • the two relay contact devices 2 are constructed identically.
  • Each of the two 1-pole relay contact devices 2 has two relay contacts 3, 4 and two the circuit between the two relay contacts 3, 4 closing or interrupting parallel contact springs 5 , which are designed as electrically conductive leaf or flat spring.
  • the one ends of the contact springs 5 are electrically conductively attached to the upper relay contact 3 in the figure, while the other, free ends 6 each carry a contact button 7 and 8 are deflectable by means of the common magnetic drive.
  • the contact springs 5 are deflected in the closed relay position shown down so that their contact buttons 7 respectively abut contact buttons 9 of the lower relay contact 4, and in the open relay position (not shown) so deflected upward that their contact buttons 7 from the contact buttons. 9 of the lower relay contact 4 are lifted.
  • the magnetic drive 8 comprises a umpolbare magnetic coil 10 with a magnetic circuit, at the two yoke legs 11, an armature (armature rocker) 12 with a permanent magnet (not shown) is pivotally held.
  • the magnet coil 10 is arranged with its axis perpendicular to the contact springs 5.
  • 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.
  • the armature 12 engages with a protruding arm 14 in an opening of an actuating element 15 , which is guided in the deflection direction of the contact spring 5 and parallel to the axis of the magnetic coil 10 linearly displaceable (double arrow 16 ).
  • the armature 12 is thus at the actuator 15 hinged.
  • a leaf spring 17 is fastened from spring steel, the free end engages the actuating element 15 each with a lateral, lower projection 18 and engages over with a lateral, upper projection 19 .
  • the actuator 15 takes with its lower projections 18, the contact springs 5 of the two relays 2 in the opening direction of the relay 2, ie upwards, and with its upper projections 19, the contact springs 5 in the closing direction of the relay 2, ie down, with.
  • the two contact springs 5 are coupled to the adjusting element 15 in the opening direction directly and in the closing direction by means of the leaf springs 17.
  • the contact springs 5 are each formed as a multilayer leaf spring with a laterally projecting from its plane arc portion 20 .
  • the two relay contact devices 2 are in the deflection of their contact springs 5, ie in the direction of displacement 16 of the adjusting element 15, spaced parallel to each other, wherein the common magnetic drive 8, i. Magnet coil 10 and the armature 12, is arranged between the two relay contact devices 2.
  • the magnetic field of the magnetic coil 10 is reversed, causing the armature 12 is pivoted and the actuator 15 is moved.
  • the actuator 15 is moved downward by the downwardly pivoted arm 14, which are deflected by the leaf springs 17 and the contact springs 5 synchronously down to the conditioning of their contact buttons 5 on the contact buttons 9 of the lower relay contacts 4.
  • the contact pressure of the contact buttons 7 to the contact buttons 9 of the lower relay contacts 4 is given by the pressure force of the actuator 15 compressed leaf springs 17.
  • the leaf springs 17 counteract the deflection of the contact springs 5 in the opening direction, which leads to a reduced-rebound closing of the two relay contact devices.
  • the armature 12 By reversing the magnetic coil 10, the armature 12 is pivoted in the opposite direction and the actuator 15 is moved in the opposite direction.
  • the actuator 15 In the open relay position, the actuator 15 is displaced by the upwardly pivoted arm 14 upwards, whereby the contact springs 5 are taken from the lower projections 18 of the actuating element 15 and the contact buttons 7 are lifted synchronously from the contact buttons 9 of the lower relay contacts 4.
