Definitions

  • the invention relates to a relay with an armature, with at least one movable contact element and with an elongated slide for transmitting the armature movement to the movable contact element.
  • the invention also relates to a method for producing such a relay.
  • the aim of the present invention is to design a relay of the type mentioned at the outset so that the adjustment to compensate for the manufacturing tolerances can be incorporated into the normal manufacturing process, namely the line cycle of mass production, using simple means, in particular requiring no multiple measurements and readjustments is.
  • this aim is achieved in that the length of the slide is individually adapted to the actual distance between the armature and the movable contact element, which is caused by the manufacturing tolerances, for a given switching state.
  • anchors or contact springs are not adapted after the complete assembly by bending or in any other way to the fixed length of the slide, but the effective length of the slide is adapted to the manufacturing and assembly tolerances of the functional parts of the relay.
  • the easiest way to do this is to produce the slider precisely to size by cutting it from a prefabricated maximum length or from a tape. It would also be conceivable to deform the slider, for example by pressing, enlarging or reducing a bead in the case of a slider made of sheet metal. A deformation of a plastic slide, for example by ultrasound, would also be conceivable.
  • the relay shown schematically in FIG. 1 shows a base 1 on which a magnet system with a coil 2, a core 3 and a yoke 4 is arranged.
  • Fixed counter contact elements 5 and 6 and a connecting element 7 for a center contact spring 8 are also anchored in the base 1; the latter forms with the two Mating contact elements 5 and 6 a changeover contact or changeover contact.
  • An armature 9 mounted on the yoke 4 forms a working air gap 10 with the end of the core 3 and, with its free end 11, actuates the central contact spring 8 via an elongated, card-shaped or rod-shaped slide 12.
  • the effective length of the armature (without taking into account the retaining lugs at the ends) is now individually selected instead of the conventional adjustment.
  • the relay is assembled in accordance with FIG. 1, but without the slide 12.
  • the system is excited so that the armature 9 rests on the pole face of the core 3.
  • the center contact spring 8 is moved into the closed position with an auxiliary pin 13, which is indicated in the drawing, until it touches the make contact element 5.
  • the distance D between the armature and the center contact spring 8 is measured at the respective points of application of the slide.
  • an amount d must then be added for the overstroke.
  • the center contact spring 8 has to be moved further after the contact has been closed in order to produce the desired contact pressure.
  • a slide dimension D + d a slide is then cut to size for each installed relay. For example, according to FIG. 3, the dimension D + d is cut off from a strip with a cutting device 14 along the cutting line 15. The lugs 16 on the slide ends have no influence on the effective length of the slide and are therefore not taken into account.
  • FIG. 4 shows the case shown in FIG. 1 with only one slide 12.
  • the end edges 15 are trimmed in order to maintain the effective slide length.
  • the end edges 17 of the slider could also be cut for length adjustment at the opposite end.
  • FIG. 5 schematically shows an embodiment with two changeover contacts lying next to one another.
  • two center contact springs 18 lying side by side in one plane are actuated via two slides 22 also lying in a common plane.
  • the armature 19 has two fork-like ends 20 and 21 for actuating the two individual slides 22.
  • the required effective length is determined independently for each of these slides 22 and is produced by cutting off at the cutting line 25. In this way, a manufacturing-related offset of the two anchor ends 20 and 21 can also be compensated for.
  • a multi-changeover relay can also be operated with a single slide, as is shown, for example, in FIG. 7 for four changeover contacts.
  • a slide 32 is actuated via an armature 29, which in turn actuates a total of four central contact springs 38 via window cutouts 33 and 34 and with its free end 35.
  • the required slide length is now determined for each of the center contact springs 38 according to the principle of the invention, and in the manufacture of the slide these different lengths are taken into account by trimming the four actuating edges 39, 40, 41 and 42.
