Definitions

  • the invention is in the field of electrical switches, which are equipped with a drive shaft coupled to a drive for moving at least one movable contact, and is applicable to the structural design of a switching mechanism for latching the shift shaft.
  • a well-known such electrical switch in which the shift shaft via a drive train against the force of at least one spring from an OFF position can be converted into an ON position, has a switch latch, wherein a coupled to the drive train pivotable first lever on a in a Verklinkungswolf held stop is supported.
  • a switch latch for transferring the stop into a release position, in which the first lever loses its support on the stop, in this case two triggering operations are provided.
  • two triggering operations are provided for transferring the stop into a release position, in which the first lever loses its support on the stop.
  • the second lever is held by means of at least one second spring in a first stop position on the first lever.
  • the work surface acts on the stop so that the stop - in the course of a compared to the "normal” triggering process "accelerated” tripping process - transferred to its release position becomes ( US 6,018,284 ).
  • the invention is based on the object to make the caused by a pivoting of the second lever "accelerated" tripping faster.
  • this object is achieved in that the forces of the two springs act independently of each other on the first lever.
  • the second lever is pivotally mounted on the first lever and the movement path of the second lever is limited by two stop surfaces of the first lever.
  • the movement of the second lever is determined only by the structural design of the first lever and the initiating force but not by other parts of the drive train or the coupling of the drive train with the first lever.
  • the second lever can therefore be combined before the assembly of the switching mechanism to a structural unit with the first lever, which forms a closed-system power. Therefore, in the first stop position, the force of the second spring does not affect the force with which the first lever bears against the stop.
  • the second lever can serve, for example, the initiating force of a magnetic release or the force of a spring accumulator.
  • the FIG. 1 shows an electrical switch 1 in the form of a low-voltage circuit breaker with a switching contact system and an associated arc quenching chamber 2.
  • the switching contact system consists of a fixed switching contact arrangement 3 and a movable switching contact arrangement 4.
  • the movable switching contact arrangement 4 has a pivotable contact carrier 5 and a plurality of contact lever. 6 on, wherein the contact lever 6 are pivotable parallel to each other and resiliently supported by means of first springs 7 under bias to the contact carrier 5.
  • the movable switching contact arrangement 4 is in a known manner via a in the FIG. 1 only schematically indicated lever assembly 8 (see also FIG. 2 ) coupled to a switching shaft 9.
  • the shift shaft 9 serves to drive not further shown, arranged parallel to the switching contact system shown further switching contact systems. It is by means of a drive device 12 from an OFF position, in which the switch contact system is open, in an ON position, in which the switch contact system is closed to transfer.
  • the drive device 12 has a drive 19 provided with a spring accumulator 18, a drive train 15 which couples the drive 19 to the shift shaft 9, and a switching mechanism 17.
  • the dial lock 17 has in a known manner on two latching devices, of which a first for latching the tensioned spring memory 18 and the second for latching against the force of the first spring 7 converted into its ON position switching shaft 9 is used.
  • the second latching device of the switch lock has a first lever 21 coupled to the drive train 15, a second lever 22 and a stop 23 configured as a half shaft.
  • the first lever 21 consists of two parallel to each other at a distance from each other arranged partial levers and is pivotable about a first pivot bearing 25 which is held stationary on a support means 14 for the drive device 12.
  • the first lever is in latched ON position of the shift shaft 9 with a Verklinkungs constitutional 24 under the force of the first spring 7 on the stop 23 at.
  • the stopper 23 is actuated via a triggering strut (not shown), for example by hand, by means of a pushbutton 10 or arranged on the front of the switch by an electromagnet 11.
  • the second lever 22 is pivotable about a second pivot bearing 26, wherein the second pivot bearing 26 is formed by a bolt which is held at its ends by the two partial levers of the first lever 21.
  • the second pivot bearing 26 is formed by a bolt which is held at its ends by the two partial levers of the first lever 21.
  • a trained on the first lever 21 pin 29 engages in a formed in the second lever slot 30, wherein the two ends of the elongated hole each form a stop surface 31 and 32 for the pin 29.
  • the one end 35 of the second spring 28 engages over a lug 36 of the second lever 22.
  • the other end 37 of the second spring 28 is supported on projections 38 of the partial levers of the first lever 21.
  • FIG. 3 is located at the first stop position of the second lever 22 on the first lever 21, a first of the two stop surfaces 31 of the elongated hole 30 under the force of the second spring 28 on the pin 29 at.
  • a ramp-like work surface 40 of the second lever 22 below the designed as a half-wave stop 23 without affecting these forces.
  • an initiating means 41 which is designed as a fast magnetic release, acts with an initiating force F directly on an actuating surface of the second lever.
  • the initiating force F may also be provided by other initiating means or mechanisms, for example by a spring accumulator.
  • the second lever 22 under the initiating force F of the initiating means 41 against the force of the second spring 28 in such a counterclockwise direction pivoted that its ramp-like work surface 40 slides along the flat bottom 42 of the half-wave while rotating the half-wave clockwise and transferred to its release position.
  • the first lever 21, the drive train 15 and the shift shaft 9 lose their support to the half-wave and the shift shaft 9 is transferred under the force of the first spring 7 in its OFF position.
  • the first lever 21 After the first lever 21 has lost its support at the half-wave and begins to pivot under the half-wave, also contribute the initiating force F and the force of the second spring 28 to accelerate the first lever 21, so that the shift shaft 9 very quickly in get their OFF position.
