Definitions

  • the invention relates to a switching device with an electromagnetic main drive, with fixed contact elements, with a movable contact piece, with a movable contact piece support, with a contact pressure spring, the movable contact piece being held in a window of the movable contact piece support by means of the contact pressure spring which, when the main drive is in the ON state, presses the movable contact on the fixed contact elements, and with an electromagnetic auxiliary drive, the coil winding of which is in series with one of the fixed contact elements and which has an additional contact pressure when the overload current flowing through the movable contact of the movable contact piece exerts on the fixed contact elements.
  • the invention has for its object to provide an electrical switching device of the above type, in which the additional contact pressure on the movable contact piece is limited upwards.
  • the drawing shows an electromagnetic main drive 1, a movable contact piece carrier 2, fixed contact elements 3, a movable contact piece 4, a contact pressure spring 5 and an electromagnetic auxiliary drive 6 of an electromagnetic switching device.
  • the electromagnetic main drive 1 essentially consists of a fixed yoke 7, a coil winding 8 and a movable armature 9 which is coupled to the movable contact piece carrier 2.
  • the movable contact piece 4 is held in a window 10 of the movable contact piece carrier 2 by means of the contact pressure spring 5.
  • the movable contact piece 4 is pressed by the contact pressure spring 5 onto the fixed contact elements 3.
  • the electromagnetic auxiliary drive 6 has a winding 15 lying in series with one of the fixed contact elements 3 as well as an armature 11 and a plunger 12 connected to it, which is connected to a lever 12 mounted in the movable contact piece carrier 2. If an overcurrent flows through the movable switching element 4, this triggers a movement of the armature 11 of the electromagnetic auxiliary drive 6, which then exerts a force on the movable switching element 4 - firstly via the contact pressure spring 5 and with greater deflection directly - and thus one causes additional contact pressure. As a result, arcs that otherwise occur between the movable contact piece 4 and the fixed contact elements 3 are avoided. Characterized in that the lever 12 is mounted in the movable contact piece carrier 2 itself, the contact pressure is limited upwards.
  • the additional contact pressure from the main circuit has the result that lower driving forces are required by the electromagnetic main drive 1 on the control side, more switching equipment or a smaller construction volume is made possible.
  • the components, such as the movable contact piece 4 and the lever 12 only have to be designed up to a certain strength limit.
  • the lever 12 is advantageously rotatably supported in the movable switching piece carrier 2 in the manner of a rocker, the end of the shorter lever arm 13 being connected to the contact spring 5, for example via a spring plate 17 with a stop, and acting on the movable switching element 4 via this or with greater deflection rests on the movable contact piece 4 and the other longer lever arm 14 is connected at the end to the armature 11 of the electromagnetic auxiliary drive 6.
  • the electromagnetic auxiliary drive 6 is mounted in the housing like the electrical main drive 1.
  • the shorter lever arm 13 according to FIG. 2 can rest directly on the movable contact piece 4 and cause the additional contact pressure.

Abstract

L'invention concerne un appareil de commutation comprenant une commande électromagnétique principale (1) pour la mise en ou hors contact d'une pièce de contact mobile (4) présentant des éléments de contact fixes (3), ainsi qu'une commande électromagnétique auxiliaire (6) provoquant, à l'état "en contact", lors d'un courant de surcharge circulant par la pièce de contact mobile (4), une pression de contact supplémentaire de la pièce de contact (4) sur les éléments de contact fixes (3). Pour le transfert de la pression de contact supplémentaire, il est prévu, conformément à l'invention, un levier (12) monté dans l'organe porteur (2) de la pièce de contact mobile.
