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, one end of each is conductively connected to the first relay contact and the other, free end of the circuit in a first relay position of the contact spring closed or interrupted in a second relay position of the contact spring, and with a magnetic drive for deflecting the contact spring in the respective relay position, wherein the magnetic drive comprises a umpolbare magnetic coil and a permanent magnet having an armature which is pivotally supported on the magnetic coil between two switching positions, and wherein the at least one contact spring in its deflection from the anchor both under attack and overlapped.
  • Such a relay is for example by DE 36 24 781 A1 known.
  • a circuit between two electrical relay contacts is closed or interrupted by means of a contact spring.
  • the contact spring is in communication with a permanent magnet of an H-armature, which is pivotally supported on two yoke legs of a magnetic coil.
  • the permanent magnet When reversing the magnetic coil, the permanent magnet and thus also the armature pivot. Since the armature both engages over and under the contact spring in its two deflection directions, this is deflected out of its closed rest position, so that the circuit is interrupted.
  • the at least one contact spring is coupled in motion in the direction of its closed relay position by means of an attached to the contact spring auxiliary spring with the armature.
  • Relay 1 shown comprises two relay contacts 2, 3 and a circuit between the two relay contacts 2, 3 closing or interrupting contact spring 4, which is designed as an electrically conductive leaf or flat spring.
  • One end of the contact spring 4 is electrically conductive to the in Fig. 1 fixed upper relay contact 2, while the other, free end 5 carries a contact button 6 and 7 is deflectable by means of a magnetic drive.
  • the contact spring 4 is in the closed relay position ( Fig. 1a ) deflected so down that their contact button 6 is applied to a contact button 8 of the lower relay contact 3, and in the open relay position ( Fig. 1b ) so deflected upward that its contact button 6 is lifted from the contact button 8 of the lower relay contact 3.
  • the magnetic drive 7 comprises a umpolbare magnetic coil 9 with a magnetic circuit, at the two yoke legs 10, an armature (rocker arm) 11 with a permanent magnet (not shown) is pivotally held.
  • the permanent magnet is arranged between two anchor plates 12 , which abut in each case on the yoke legs 10 in the two switching positions of the armature 11.
  • the magnetic coil 9 and the pivotable between its two switching positions armature 11 form a H-anchor suit.
  • the armature 11 has a radially projecting arm 11 a , which engages under the contact spring 4 in the deflection direction (double arrow 13 ) with a lower projection 14 and engages over an upper projection 15 .
  • the contact spring 4 in the deflection 13 between the two projections 14, 15 is arranged.
  • an additional leaf spring 16 is attached from spring steel whose free end is overlapped by the upper projection 15.
  • the armature 11 takes with the lower projection 14, the contact spring 4 in the opening direction of the relay 1, ie upwards, and with the upper projection 15 by means of the additional leaf spring 16, the contact spring 4 in the closing direction of the relay 1, ie down, with.
  • the contact spring 4 is coupled to the armature 11 in the opening and closing direction.
  • the contact spring 4 is formed as a multi-layered leaf spring with a bow portion 17 protruding laterally out of its plane.
  • the magnetic field of the magnetic coil 9 is reversed, whereby the armature 11 is pivoted and thereby the contact spring 4 is deflected.
  • the closed relay position ( Fig. 1 a) is the contact spring 4 deflected by the upper projection 15 of the downwardly pivoted arm 11a down to the contact of their contact button 6 to the contact button 8 of the lower relay contact 3.
  • the contact pressure of the contact button 6 to the contact button 8 of the lower relay contact 3 is given by the pressing force of the leaf spring 16 compressed by the armature 11.
  • the leaf spring 16 counteracts the deflection of the contact spring 4 in the opening direction, which leads to a bounce-reduced closing of the relay 1.
  • the open relay position the contact spring 4 is deflected upward by the lower projection 14 of the upwardly pivoted arm 11a and thereby the contact button 6 is lifted from the contact button 8 of the lower relay contact 3.
  • the leaf spring 16 is divided by a bend in a fastening-side rear spring portion 16a and an angled toward the contact spring 4 front spring portion 16b .
  • FIGS. 2a and 2b show, when closing the relay 1, the upper projection 15 of the armature 11 acts first on the rear spring portion 16a and then on the angled front Spring section 16b.
  • the spring characteristic of the two spring portions 16a, 16b are each set differently.
  • Fig. 4 shown double contact relay 1 ' characterized in that here two parallel contact springs 4a, 4b are provided.
  • Each contact spring 4a, 4b carries at the free end 5a, 5b a contact button 6a, 6b, which cooperates with a contact button 8a, 8b of the lower relay contact 3.
  • the two contact springs 4a, 4b are arranged analogously to the single contact relay 1 in the deflection 13 between an upper and a lower projection of the armature 11 and are deflected by the rotational movement of the armature 11 together down to the closed relay position or upward to the open relay position.
