Definitions

  • the invention relates to a contact arrangement for a switching device with multiple interruption through parallel contact contact points of two contact bridges guided in a contact actuator via a spring plate for the contact pressure spring, the spring plate having cuts transversely to the direction of suspension, into which the contact bridges can be locked with the spring plate transversely to their longitudinal direction can be inserted.
  • the spring plate is guided with flat surfaces in the contact actuator.
  • the contact bridges in the spring plate have a relatively large amount of play, and they themselves are also designed to be elastic.
  • the present invention has for its object to avoid tilting of the spring plate in the slide guide and to enable reliable contacting of the two contact bridges even when the two fixed contact pieces are not evenly aligned. This is easily achieved in that. the spring plate at least on two opposite. transverse to the longitudinal direction of the contact bridge sliding surfaces of the spring plate is rounded in the contact actuator.
  • the spring plate protrudes beyond the longitudinal sides of the contact bridges and is encompassed in a U-shape by the contact actuating member and rounded in the outstanding area on each of the two mutually perpendicular sliding surfaces is.
  • the spring plate consists of a thermoplastic molding material.
  • the spring plate has an essentially H-shaped cross section. On both long sides of the H there are recesses for the spring.
  • the contact arrangement shown in the drawing for a switching device with multiple interruptions consists of two contact bridges 1, 2, which are provided with the contact pads 3 forming the contact contact points, the spring plate 4, the contact pressure spring 5 and the actual contact actuator 6.
  • the contact actuator 6 has a window-shaped opening 7, on one side of which the contact pressure spring 5 is supported and on the other side - as shown in FIG. 3 - the contact bridges 1 and 2 rest over the spring plate 4.
  • the spring plate has incisions 8 in the side into which the contact bridges 1 and 2 are inserted; Nubs 9 on the contact bridges 1, 2 snap into corresponding side recesses 10 in the spring plate 4, so that a certain mobility of the contact bridges 1, 2 relative to the spring plate 4 remains. However, a shift is not possible.
  • the spring plate with the part 11 protrudes beyond the long sides of the contact bridges 1, 2.
  • the parts 11 are surrounded by U-shaped recesses 12 in the side walls of the contact actuator, so that the spring plate is slidably guided both on the side walls 13 of the window-shaped opening 7 and on the walls 14 running perpendicular thereto.
  • the sliding surfaces 15 of the spring plate facing the side walls 13 and 14 are rounded both with respect to the side wall 13 and with respect to the side wall 14. This results in the possibility that the contact bridge tilt both in the longitudinal direction together with the spring plate and transversely thereto, d. H. can move so that the contact bridges can rotate on the one hand to crooked fixed contact parts 16 and around its longitudinal axis to compensate for tolerances.
  • the two pivot directions are represented by the arrows 17 in FIGS. 1 and 18 in FIG. 3.
  • the possibility of pendulum of the spring plate thus results in an optimal adaptation of the contact bridges to the fixed contact parts without fear of jamming of the spring plate in the guide.
  • the latter is divided here into a lower part 19 and an upper part 20, which can be joined to the contact bridges, for example by snap connections after the spring has been inserted into the spring plate.
