Definitions

  • the invention relates to a relay according to the preamble of claim 1.
  • the pole sections of the contact system are separated from one another either only by air gaps or by fixed ribs, the comb mostly being T-shaped or U-shaped and supported on the armature and the moving parts, or engaging in these.
  • the disadvantage of these known relays is that there can be a flashover between the pole paths in the event of overvoltages if the separation is only by air gaps, and that the required air and creepage distances between the pole gaps of the contact system make the miniaturization difficult when using ribs .
  • the aim of the invention is to avoid these disadvantages and to propose a relay of the type mentioned in the introduction in which a flashover between the pole paths is prevented in a simple manner and a miniaturized design is possible.
  • the features of claim 2 have the advantage that the comb can be kept relatively small and has sufficient rigidity even with a small thickness.
  • the relay has a base body 1, in which the fixed contacts 2 and 3, or the contact carriers 20, 3 'are inserted.
  • the contact system has two pole sections, only one of which is shown in FIG. 1.
  • a coil 4 is also held in the base body and receives a magnet system.
  • An armature 5 engages in a comb 6, which rests on the top of the receptacle of the coil 4 and is displaceable thereon.
  • the comb 6 is essentially lyra-shaped and holds a tab 7 between the lugs 8. This tab 7 is guided in a groove 9, which is incorporated in a web 10 arranged between the pole sections of the base body 1, the groove 9 in a header 11 of the web 10 is arranged.
  • the lugs 8 of the comb 6 also serve as drivers for the movable contact spring 12, which carries a movable contacts 23.
  • This contact spring 12 is essentially U-shaped and is fastened to a contact carrier 12 ', which also has a connecting lug 13.
  • the fixed contact 21 is also provided with a connecting lug 14, as is the contact carrier 3 ', which has a connecting lug 15, the connecting lugs passing through the base body 1.
  • a resilient holder 21 with rivets 22 is fastened to the contact carrier 3 ', in which the fixed contact 3 is held.
  • the tab 7 can also be guided in a groove 16 of a cover 17, which is incorporated in an inwardly projecting strip 18.
  • the tab 7 is guided in a groove 18 which is arranged in a strip 19 of the end wall of the cover 17, the strip 19 projecting into the interior of the cover 17.
  • the tab 7, which, like the comb 6, is made of an electrically insulating material, separates the two pole sections of the contact system, only one of which 2, 3, 12 is shown, in connection with the web 9 and the strip 18 of the cover 17.
