Definitions

  • the invention relates to a switching mechanism according to the preamble of claim 1.
  • Such a switching device is in the circuit breaker S 2 from ABB Stotz-Kontakt GmbH, Heidelberg, installed and therefore known.
  • This rear derailleur has a switch toggle, which is via a switch lock located between two circuit boards moving contact piece remaining in the off position in the on position and vice versa, with a dead center position of the key switch during the switch-on movement is crossed.
  • the switch-on movement runs so that the movable switching knob is pivoted; this is about an associated Lever the contact lever, which carries the movable contact piece, driven; this Switch-on movement of the movable contact piece runs according to the speed, with which the shift knob is pivoted.
  • the object of the invention is to provide a switching mechanism of the type mentioned in the introduction, where the switch-on speed of the contact point is independent of the switch-on speed the operator.
  • a second latching point is provided, which is a fixed one Has contact point for a lever coupled to the movable contact piece, and according to the invention a trigger element is coupled to the switching knob, which unlocked second latching point, so that the movable contact piece accelerates moved to the off position.
  • the trigger element and thus the movable contact piece be held in an intermediate position, from which it is not released until the second Locking point reaches the final switch-on position.
  • a slide is provided, which is coupled to the switch to unlatch the second latch, the slide only at a certain position, intermediate position, of the shift knob engages with this and opens the second latching point.
  • a circuit breaker which has a pivotable contact has, on which the movable contact piece is attached, then in the axis of rotation of the contact lever, a holding part can be rotatably mounted, which with the trigger element the second latching point is coupled and from this in the specific Intermediate position is recorded. The contact lever is then in this particular intermediate position held by the holding part.
  • a return spring for Trigger element can be arranged, the trigger element permanently in the latching direction acted upon.
  • the return spring Conveniently designed as a two-arm coil spring, one arm against the release element and the other arm against an abutment nose on the contact lever is present.
  • Fig. 1 shows a circuit breaker 10 with a housing 11, the upper housing part is removed so that an insight into the circuit breaker is granted is.
  • the circuit breaker 10 has a switch toggle 12 which emerges from an opening 13 of the circuit breaker 10 protrudes and in the area of the front wall 14 by one Axis of rotation 15 is pivotally mounted.
  • the axis of rotation 15 is between two plates 16 stored, which have an approximately L-shaped shape, the longer leg about runs parallel to the front wall 14, whereas the short, perpendicular to it Leg 18 carries the pivot axis 15.
  • the axis of rotation is between the two plates 16 19 of a movable contact lever 20 mounted, which is designed as a double arm lever is, one arm is coupled to a drive bracket 21 which on the Switch toggle 12 is articulated, whereas the other arm is a movable contact piece 22 carries, which cooperates with a fixed contact piece 45.
  • a holding part 23 is rotatably mounted on the contact lever 20 and has a first nose 24 and has a second nose 25, the first nose approximately to the movable contact piece 22 protrudes, while on the second nose 25 serves as a release element 26 Is hinged, which rests with a leg 27 against a step 28, which is provided in one of the boards 16.
  • To form the level 28 is in one board 16 has an approximately L-shaped recess 29, one leg of which Gradation 28 and the other leg 30 form a pocket, which is further below to be explained.
  • a first stop 31 on the movable contact lever 20 There is a first stop 31 on the movable contact lever 20.
  • a second stop Stop 32 is formed on the upper board 16, the first stop 31 with the nose 24 and the second stop 32 with an approximately perpendicular to the connecting line of the two lugs 24 and 25 extending third lug 33 cooperates.
  • a return spring 34 is arranged around the holding part or element 23 one leg 35 bears against the stop 32 and the other leg 36 itself is supported on a shoulder 37 on the bracket 26 so that the bracket under the force of the spring 34 is pressed continuously in the direction of arrow P, whereby the holding element 23 continuously is applied clockwise.
  • a slider 38 on the circuit board 16 is displaceable perpendicular to the extension of the bracket 26 integrally formed, which has two elongated holes 39 and 40, in which to guide the projections 41, 42 arranged on the board 16 engage.
  • On the slide 38 is one of Slider formed from the protruding paragraph or step 43, the engages over the bracket 26.
  • Fig. 1 shows the circuit breaker in the off position. If the circuit breaker is to be switched on, then the switching knob 12 is clockwise pivoted, whereby the drive bracket 21 between the switching toggle 12 and the movable contact lever pivots this counterclockwise, so that the movable contact piece 22 moves towards the fixed contact piece 45. During this switch-on movement, the nose 31 of the movable contact lever lies down against the nose 24 and since the bracket 26 is supported against the step 28, the movable contact piece initially remains in the position shown in FIG. 2 stand in which the distance of the movable contact piece 22 to the fixed Contact piece 45 is reduced. The slide 38 also remains at rest.
  • the switching knob lays down with its drive bracket 21 leading extension 12a against a projection 44 on the slide 38, see Fig. 3 and with further pivoting of the shift knob 12, the extension 12 presses Switch toggle 12 against the projection 44 and moves the slider 38 in the direction of the arrow P1, so that this over the gradation 43 the bracket 26 to the left against Pivoted clockwise so that the leg 27 is released from the step 28 and can wander into the pocket 30.
  • the holding element 23 is released and can twist counter-clockwise, making it also movable Contact lever 20 allows the final switch-on movement in which the movable Contact piece 22 comes into contact with the fixed contact piece 45, see Fig. 5.
  • This latter movement, in which the web 27 snaps into the pocket 30, is a quick movement and is (not shown) so that ultimately the switch-on movement from the position according to Fig. 4 in the position shown in FIG. 5 always runs at the same speed.
