Definitions

  • the invention relates to a relay for switching high
  • the object of the present invention is to develop a relay for switching high currents in such a way that high currents / powers can be switched with relatively low drive powers, such as can be provided by electronic control circuits, while ensuring the necessary distances (creepage / clearance distances ) between control circuit and load circuit (contact circuit) as well as particularly robust connections for the load circuit.
  • the invention is characterized in that the relay has a polar drive system with a permanent magnet and a switching system with double contact interruption.
  • An essential feature of the present invention is therefore the design of the relay with a polar drive system (bistable switching behavior). This makes it possible, for example, to control the relay according to the invention from an electronic circuit with TTL level, with which very high currents / powers can be switched due to the design of the contact system with double contact interruption. So the features of a contactor (high switching capacity) are combined with the features of a relay with low drive power. This combination feature, which is essential to the invention, achieves significant advantages at the same time:
  • a drive system with low drive power is achieved by using a polar drive system, which is particularly bistable.
  • this drive system can then be switched depending on the direction.
  • the permanent magnet supports the switching behavior in that from a certain pivot point of the armature the field of the permanent magnet and the electromagnetic field of the coil are rectified in their force effect and therefore a faster and more sensitive response of the armature to lower drive power is the result.
  • pull-type clamps the relay can be switched directly into a power circuit as a power relay, because the robust pull-type clamps can be used to directly connect wires with a large cross-section. This results in a significant simplification of circuitry and wiring for the compact arrangement.
  • the relay consists of a spring block 1, on which the clamp clamps, consisting of the hollow clamps 21 and the cheese head screws 22, are arranged. These clamp clamps are connected to the corresponding contact pieces via connecting brackets 23.
  • the spring block 1 is with the help of cheese head screws 18 on the yoke 3 of the drive systems releasably attached.
  • the drive system consists of the bobbin 2, the yoke 3 and the yoke 4 arranged on the other side of the bobbin, which is fastened to the spring block 1 by means of a countersunk screw 19.
  • the magnetic circuit to the core 5 is produced via the yokes 3, 4.
  • the magnetic circuit closes by means of a permanent magnet 8, which is received between a bearing plate 10 of a pivotable armature 9, which is mounted on the relay in the pivot point 24.
  • a lever 7 On the armature receptacle 28 of the armature 9 there is a lever 7 which protrudes through a recess in the hood 20 of the relay, so that with the position of the lever 7 of the armature receptacles 28 there is a switch position indicator and a possibility for manual switching of the armature 9.
  • connection of the coil former 2 are led out at solder connections 6 for connection to an electronic drive system.
  • the contact system with double contact interruption consists in that a cylindrical pin 15 is fastened in a recess in the armature receptacle 28 of the armature 9, on which a contact bridge 14 is arranged so as to be axially displaceable.
  • the contact bridge 14 is acted upon from both displacement sides by compression springs 16, which act on corresponding disks 17 on each end face of the contact bridge 14.
  • the contact bridge 14 In the position shown in FIG. 3, the contact bridge 14 is in direct contact with the contact pieces 27 arranged on this side, the supply to the tension clamp clamps taking place via associated connecting clamps 23. The contact bridge 14 is pressed against the associated contact piece 27 under the force of the compression spring 16. The contact bridge 14 can therefore be pivoted due to the mounting on the free, pivotable end of the armature 9 in the intermediate space 25 between the contact pieces 26, 27.
  • FIG. 2 it is shown that a total of three tension clamps with three angular contacts 11, 12, 13 are provided.

Abstract

Le relais, destine a commuter des courants/ puissances eleves, est constitue d'un corps de bobine (2) avec noyau (5) et d'une culasse (4) associee agissant sur une armature (9) disposee de maniere pivotante dans le boitier du relais, qui actionne les contacts suivant sa position. Afin de permettre de commuter des courants/puissances eleves a l'aide de circuits de commande electroniques, le relais presente un systeme d'entrainement polarise ayant un aimant permanent (8) et un systeme de commutation ayant une double coupure de contact.
