Definitions

  • the invention relates to a drive device for an electrical switch with pressure contacts, in particular for a vacuum switch according to the preamble of claim 1.
  • Such a drive device is known for example from DE-GM 81 09 229.6.
  • the lever mechanism has an angle lever.
  • an S-shaped link is formed, into which a fixedly anchored pin engages, while the drive rod is articulated at the end of the other arm.
  • the pivot axis of the angle lever is attached to a plunger which is coaxial with the contact plunger and how it can be moved longitudinally. If the angle lever is pivoted, its pivot axis rises or falls, since a fixed pin engages in the S-shaped link.
  • the counterforce emanating from the compression spring surrounding the plunger generates in cooperation with the S-shaped link the pivot axis of the angle lever attached to the ram shear forces, not only by this pivot axis but also by the guidance of the ram are to be included and also stress the ram to bend.
  • the proposed drive device has the features defined in the characterizing part of patent claim 1.
  • the drive device 10 shown has a box-shaped housing 11 on which an only partially visible vacuum interrupter 12 of a vacuum switch is supported and which in turn is anchored to the rear wall of a drive (not shown) via a support insulator 13.
  • the support insulator 13 is anchored to the end wall 14 of the housing 11, while the side walls of the latter are designated 15 and 16.
  • a contact plunger 17 which carries the movable contact piece (not shown), is led out of the vacuum interrupter 12, which contains the switching contacts of the vacuum interrupter, in a vacuum-tight manner, but can be moved out longitudinally.
  • the lower, free end of the contact plunger 17 carries a guide pin 18 running at right angles to it, which extends at both ends through elongated holes 19, 20 formed in the side walls 15, 16 and extending parallel to the direction of movement of the contact plunger 17 and there e.g. is secured by means of split pins 21 'or similar securing elements.
  • a connecting rod 25 is articulated on the guide pin 18 via elongated holes 21, 22 which are formed in the legs 23, 24 of its forked end. This forked end of the connecting rod 25 is surrounded by a sleeve 26 which is displaceable thereon and which is penetrated transversely by the guide pin 18 without play.
  • the lower end of the connecting rod 25 has a shoulder 27 and is also bifurcated.
  • the two legs 28, 29 at the lower end of the connecting rod 25 are penetrated without play by a pin 30 parallel to the guide pin 18, which extends through the sides at both ends walls 15, 16 formed, congruent, S-shaped slots 31, 32 extending therethrough and there also secured by split pins 33.
  • the two S-shaped slots 31, 32 together form the S-shaped backdrop.
  • the two legs 28, 29 at the lower end of the connecting rod 25 engage around one end 34 of a drive rod made of electrically insulating material, into which the pin 30 is pressed and which can be moved back and forth in the sense of the double arrow 36 by means of a drive unit, not shown.
  • the connecting rod 25 is surrounded by a compression spring 37 which is supported at one end on the shoulder 27 and at the other end on the lower end face of the sleeve 26.
  • the compression spring thus acts via the sleeve 26, which is pivotable but not axially displaceable with respect to the contact plunger 17 and via the guide pin 18 on the contact plunger 17th
  • Fig. 1 the switch-on position is shown in solid lines. It can be seen that the guide pin 18 does not abut the lower end of the elongated holes 21, 22. The connecting rod 25 is therefore not loaded.
  • the compression spring 37 tensioned in the switched-on position acts on the sleeve 26 and, via this, on the guide pin 18, which, however, can only move parallel to the direction of movement of the contact plunger thanks to the elongated holes 21, 22.
  • the compression spring 37 is at an angle to Contact plunger is, this is only exposed to the force component effective in its direction of displacement, while the transverse force component is supported via the ends of the guide pin 18 in the elongated holes 19, 20.
  • the contact plunger is not subjected to any bending stress.
  • the drive device 10 is designed such that the contacts of the vacuum switch come into contact when the connecting rod 25 is in a position aligned with the direction of displacement of the contact plunger 17, as indicated in FIG. 1 by the dashed line 38 .
  • This can be done, for example, by changing the length of the outside End of the contact plunger 17, for example, are set with an adjusting nut 39.
