Definitions

  • the present invention relates to an electrical switching device with separable contacts.
  • Electrical switching devices with separable contacts such as low-voltage circuit breakers, generally comprise, for each pole, a fixed electrical contact and a movable electrical contact which can be moved relative to each other by means of a mechanism switch to interrupt the flow of an electric current.
  • the patent EP-2 801 099-B1 describes an example of a switchgear.
  • a disadvantage of known switching devices is that, when the switching mechanism is actuated to separate the fixed and movable contacts in order to interrupt the flow of current, the movable contact may close accidentally once it has reached the end of the opening stroke. , for example due to an uncontrolled rebound of one or more moving parts of the switching mechanism.

  • the abutment 24 comprises a rod or a rigid protrusion projecting relative to the armature 20 while extending parallel to the axis X18.
  • the stop 24 limits the movement of the control lever 18 between the first position and the second position by coming into contact with the first and second arms so as to block the rotation of the shaft.

  • the first arm and the anti-rebound lever 26 are not necessarily both constantly in direct contact with the stop 24, so that a small clearance in the vicinity of the second position can be authorized in such a case for the control lever 18.
  • the pivot link connecting part 22 to control lever 18 is mounted on the first arm.
  • the pivot link connecting the control lever 18 to the anti-rebound lever 26 is mounted on the second arm.

  • the anti-rebound lever 26 covers the rounded portion and the upper edge of the anti-rebound lever 26 is aligned with the outer edge of the rounded portion. The anti-rebound lever 26 then does not protrude from the rounded portion, so as not to hinder the movement of the control lever 18 and of the shaft.

  • the bearing 30 comprises a connection portion 36 in the shape of a lobe to which the connecting piece 32 is connected.
  • the anti-rebound lever 26 and the bearing 30 are configured such that the contact portion 28 is in contact against an edge of the bearing 30 when the anti-rebound lever 26 is in its rest position and that the contact portion 28 moves along said edge when the control lever 18 rotates around the bearing 30.
  • the contact portion 28 is kept in direct contact against the edge of the bearing 30 under the effect of an elastic return member, such as a torsion spring, which tends to bring back the anti-rebound lever 26 towards its rest position.
  • an elastic return member such as a torsion spring
  • the torsion spring is for example mounted associated with the anti-rebound lever 26.
  • the bearing 30 comprises, on said edge, a guide portion 34 in the form of a cam configured to push the anti-rebound lever 26 towards its deployed position.
  • the edge of the bearing 30 comprises an inclined part which locally moves away radially from the axis of rotation X18 to form at least a first part of the guide portion 34.

  • the switching mechanism is triggered to open the device 4, i.e. to separate the contacts 6 and 8 and to interrupt the current.
  • control lever 18 is rotated around the axis X18, for example by turning the shaft in a first direction of rotation, illustrated by the arrow F1 on the figure 2 .
  • This movement is transmitted by part 22 to moving contact 8 which then rotates around axis X8 in a second direction of rotation, illustrated by arrow F2.
  • the anti-rebound lever 26 remains in the rest position, i.e. it remains stationary with respect to the control lever 18.
  • the anti-rebound lever 26 rotates with the control lever 28 around the axis of rotation X18 with respect to the fixed bearing 30. In doing so, the contact portion 28 follows the edge of the bearing 30, for example by sliding at the contact along this edge.

  • the control lever 18 has also started to leave the second position and the first arm has started to move slightly away from the stop 24.
  • control lever 18 can no longer continue to move away from the second position, which prevents accidental reopening of the contacts 6 and 8.

  • the anti-rebound lever 26 prevents the control lever 18 from leaving its second position, by cooperating with the stop 24, even if the control lever 18 bounces against the stop and has started to move away from it, as this is the case here.
  • the control lever 18 then remains close to the second position. Contact 8 therefore cannot close accidentally.
  • the movement of the anti-rebound lever 26 is not dependent on the speed of rotation of the control lever 18.
