Definitions

  • the present invention relates to a relay having at least one, the circuit between two relay contacts closing or interrupting electrically conductive contact bridge and a magnetic drive having a umpolbare magnetic coil and a permanent magnet having rocker arm, which is held pivotably on the magnetic coil between two end positions
  • Such a relay with rotary anchor rocker is for example by the DE 101 62 585 C1 or DE 102 49 697 B3 known.
  • a circuit between two electrical relay contacts is closed or interrupted by means of one or more contact springs.
  • the contact springs are connected via a displaceable actuating element in conjunction with a permanent magnet of a H-armature (rocker arm rocker), which is pivotally supported on two yoke legs of a magnetic coil.
  • H-armature rocker arm rocker
  • 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 contact bridge is provided on the armature rocker and electrically conductive in one, closed end position of the armature rocker on both relay contacts and is lifted in the other, open end position of the armature rocker of at least one of the two relay contacts.
  • the at least one contact bridge is provided on a relative to the pivot axis of the armature rocker radially projecting arm of the armature rocker. In another preferred embodiment, the at least one contact bridge is arranged in an axial plane of the pivot axis.
  • a leaf spring is electrically conductively attached to the two relay contacts, wherein the at least one contact bridge in the closed end position of the armature rocker at the free ends of the leaf springs, this deflecting, electrically conductive abuts and in the open end position of the armature rocker of at least one of the two Leaf springs, preferably from both leaf springs, lifted is.
  • the contact force is generated by the prestressed leaf spring, which is deflected by the anchor rocker.
  • a housing-side stop holds the leaf spring in position so that the bias is maintained and a defined contact spacing can be maintained.
  • the leaf springs engage with their free ends their respective relay contact in the opposite direction to form a zigzag arrangement.
  • the contact force acting on the contact bridge is increased by the magnetic repulsive force exerted by the magnetic field of the relay contacts through which current flows in the opposite direction.
  • the contact bridge is pluggable, latched or connected as a plastic insert with the anchor rocker.
  • relay 1 has two relay contacts 2, 3, a pivotally arranged therebetween contact bridge 4 for closing or interrupting the circuit between the two relay contacts 2, 3 and a magnetic drive 5 for pivoting the contact bridge 4.
  • the magnetic drive 5 comprises a umpolbare magnetic coil 6 with a magnetic circuit, on whose two yoke legs 7 a rotary armature rocker 8 with a permanent magnet (not shown) is pivotally held about the pivot axis 9.
  • the permanent magnet is arranged between two anchor plates 10 , which rest in the two end positions of the armature rocker 8 in each case on the yoke legs 7.
  • the magnetic coil 6 and the pivotable between its two end positions anchor rocker 8 form a H-anchor suit.
  • the armature rocker 8 has a respect to the pivot axis 9 radially projecting arm 11 which carries the armature rocker 8 at its free end.
  • the contact bridge 4 has two contact buttons 12 , which are arranged on both sides of the arm 11, but on different sides of the contact bridge 4 and electrically connected to each other by a copper track 13 .
  • the two contact buttons 12 are also arranged transversely spaced from one another in the direction of the pivot axis 9.
  • the contact bridge 4 is plugged or latchably connected to the armature rocker 8 or manufactured as a one-piece plastic injection molded part with the copper sheet 13 and the contact buttons 12 as an insert.
  • the armature rocker 8 is mounted about two pivot pins 14 in the relay housing 15 about the pivot axis 9.
  • the two relay contacts 2, 3 are two copper contacts , which are fixed at their opposite contact ends 2a, 3a in the relay housing 15 and the free contact ends 2b, 3b parallel and in the direction of the pivot axis 9 transverse to each other and overlap each other.
  • Fig. 1 extends the arm 11 in a radial plane between the two free contact ends 2b, 3b of the two relay contacts 2, 3.
  • a leaf spring 16 is electrically conductively attached, at its free end a contact button 17 to rest on Contact button 12 of the contact bridge 4 has.
  • the leaf springs 16 engage with their free ends their respective relay contact 2, 3 in the opposite direction, so that the relay contacts 2, 3 together with the leaf springs 16 and the contact bridge 4 form a zigzag arrangement.
  • Fig. 1a the relay 1 is shown in its open relay position, in which the contact rocker 8 is pivoted into its one end position and thereby the contact bridge 4 with its two contact buttons 12 is lifted from the contact buttons 17 of the leaf springs 16 and thus the two relay contacts 2, 3 not together connects electrically.
  • the free ends of the leaf springs 16 are each biased against a housing-side stop 18 , which also defines a defined contact distance between contact bridge 4 and leaf spring 16.
  • the relay 1 is shown in its closed relay position, in which the contact bridge 4 rests with its two contact buttons 12 on the contact buttons 17 of the leaf springs 16 and thus electrically connects the two relay contacts 2, 3 together.
  • the Fign.3 to 5 show the armature rocker 8, each with modified contact bridges 4.
  • the in Fig. 3 shown contact bridge 4 has four contact buttons 12 - each two on both sides of the arm 11 and on different sides of the contact bridge 4 - on, with all the contact buttons 12 are electrically connected to each other by the copper track 13. This contact bridge 4 is used to close or interrupt the same circuit.
  • Fig. 4 From the contact bridge of Fig. 3 is different in the Fig. 4 shown contact bridge 4 in that here two contact bridges 4a, 4b are provided with two copper tracks 13a, 13b , through which two contact buttons 12 are electrically connected to each other. These contact bridges 4 are used to close or interrupt the same circuit or two different circuits.
