Definitions

  • the invention relates to a mains isolating relay in miniature format with switch contacts with an armature which can be pivoted by the coil voltage of a magnetic coil and a plunger arrangement which, starting from the armature, switches resilient switching springs guided in end stops.
  • shocks deflect the switching springs in particular on one side, which disadvantageously requires a relatively large armature stroke for a predetermined contact distance.
  • the object of the invention is to develop a relay of the type mentioned so that with a very small armature stroke of about 0.5 mm, a large switching spring deflection is achieved in the manner of the industrial standard, bearing tolerances of the articulated plunger and tolerances of the armature stroke being compensated for at the same time .
  • the essence of the invention is that a large contact distance is achieved via the closely spaced intermediate levers.
  • Lever 4 deflects switch spring 12.
  • the tolerance of the armature stroke X is in relation to the selected translation in relation to the deflection of the Contact spring 12- transferred according to the gear ratio.
  • the tappets in particular in the area of the support surface on the arm of the anchor rocker, are provided with a contact surface (see laid-open specification DE 36 11 049A1).
  • an intermediate lever is arranged at a fixed angle to the mounting of the other intermediate lever.
  • a smooth intermediate bearing in particular made of Teflon, is arranged in the area of the fixed intermediate levers 7, 8.
  • switching springs 11, 12 are provided, on the underside of which a pressure surface 13 of the plunger 4, 6 is applied.
  • the switching springs 11, 2 each carry a switching contact 14 at the ends.
  • the ends of the switching springs 11, 2 can each be limited to an end stop 15 in the rest or working position.
  • the plunger 6 carries intermediate levers at its end in the area of the bearing B, which could move up and down in the area of the bearing tolerance 16 as well as the bearing tolerance 17 in the area of the bearing A.
  • the intermediate lever 8 is provided downward according to the course of gravity, while the intermediate lever 7 is inclined obliquely in the direction of the bearing B, smooth intermediate bearings 9 being provided in the region of the contact surfaces of the intermediate lever.
  • the plunger 4 lies with an advantageously round contact surface 3 according to the exemplary embodiment here on the leg 2, which is long here, and according to the representation of the rocker arm 5, the leg 1 could also be arranged in this area.
  • the short leg 1 is through the magnetic coil 18 folded back and forth on the bearing 10, the switching springs 4, 6 also flipping up particularly rapidly in the cycle of the leg 1, the bearing play acting in the sense of increased acceleration due to the reduced friction.
  • the plunger 4 When the plunger 4 is lowered on the leg 2, which is long in the exemplary embodiment, the plunger 6 is raised via the intermediate bearing 9 and vice versa.
