Definitions

  • the document FR-A 798 188 describes an abrupt closing mechanism for a circuit breaker, having three levers hinged together to form two toggles arranged between the contact carrier bar and the lever.
  • One of the extreme levers is made integral with the bar, and is provided with a spout capable of cooperating during the closing stroke with a first boss of the lever.
  • the lever is connected to the other extreme lever by an accumulator spring.
  • the lever comprises a second boss coming into abutment against a lug of the lever to limit the closing stroke of the lever.
  • the spring is banded until the engagement of the first boss against the beak of the lever, causing the release of the lever of the first toggle.
  • the abrupt movement of rotation of the lever ensures the displacement of the bar towards the closed position. This movement is stopped when the lug of the lever abuts against the second boss of the lever.
  • Another adjustable stop is necessary to limit the stroke of the intermediate lever. Such an arrangement is complicated and risks generating twists of the contacts, with in addition a certain force of actuation of the lever for the closing operation.
  • the object of the present invention is to provide a simple mechanism for abruptly closing the contacts of a power cut device, the actuation of which requires normal force without excessive hard point when the accumulator spring comes into action.
  • the retaining plate is pivotally mounted in a bearing of the housing and is biased towards the active position by a biasing spring bearing on a flange situated opposite the bearing.
  • the accumulator spring advantageously consists of a helical torsion spring housed around the pivot axis of the handle in a cylindrical cavity in the body of the handle.
  • an abrupt closing device 10 is incorporated in the control mechanism of an electric current cut-off device, in particular a miniature low-voltage circuit breaker with a molded insulating case 12.
  • the mechanism of each pole includes a tilting lever 14 of my noeuvre manually connected by a kinematic chain transmission 16 to a contact arm 18 supporting the movable contact 19 cooperating with a fixed contact 10.
  • the discoursetiqe 16 of the mechanism chain is described in detail in French Patent No. 2,344,950, but the triggering members of the mechanism have not been shown in FIGS. 1 to 4.
  • the kinematic chain 16 comprises a rocker arm 22 rotatably mounted on a fixed axis 24.
  • One of the branches 25 of the rocker arm 22 carries a pivot 26 on which the contact arm 18 is pivotally mounted, cooperating with a hooking stop belonging to the trigger lever (not shown).
  • the contact arm 18 In the active position of the hooking stop, the contact arm 18 is locked on the rocker arm 22, so as to constitute a bidirectional connection between the lever 14 and the contact arm 18.
  • the contact arm 18 In the unlocked position of the hooking stopper , following a triggering of the mechanism on fault, the contact arm 18 is unlocked relative to the rocker arm 22, causing the breaking of the mechanical connection between the lever 14 and the contact arm 18.
  • An opening spring (not shown) Then causes separation of the contacts 19, 20, independently of the lever 14. The operation of such a mechanism is well known to specialists, and it is unnecessary to describe it in more detail.
  • the snap closure device 10 is composed of a spring 30 energy accumulator housed in a cylindrical cavity 32 of the body 34 of the lever 14, and of a retaining plate 36, cooperating with the kinematic chain 16 of the mechanism.
  • the tilting lever 14 is rotatably mounted between two extreme closing and opening positions on a fixed transverse axis 38 positioned in aligned bearings of the housing 12.
  • the energy storage spring 30 is constituted by a helical torsion spring s' extending in the cavity 32 coaxially around the axis 38.
  • One of the ends 31 of the accumulator spring 30 is engaged in a slot in the body 34 of the lever 14, while the other opposite end 33 is secured to an intermediate lever 40 for supporting a transmission link 42.
  • the branch 44 of the rocker arm 22 located opposite the pivot 26 is attached to the rod 42, formed by a U-shaped bracket.
  • One of the arms of the link 42 is articulated on the lever 40, pivotally mounted on the axis 38, and the other arm is guided inside a slot 46, formed in the retaining plate 36.
  • the transmission link 42 and the intermediate lever 40 constitute a toggle arranged between the lever 14 and the rocker arm 22.
  • the light 46 of the retaining plate 36 is provided with a boss 48, arranged to form an erasable stop, cooperating with the link 42.
  • the body 34 of the lever 14 is equipped with an unlocking lug 50 moving in a circular trajectory, when the lever 14 is tilted.
  • the retaining plate 36 is pivotally mounted on a shoulder or bearing 52 of the housing 12 so as to occupy an active locking position or a cleared unlocking position.
  • the plate 36 has a flange 54 cooperating with a biasing spring 56 which biases the plate 36 counterclockwise towards the active position, allowing the connecting rod 42 to come into abutment against the boss 48 ( Figure 2) during the closing operation of the handle 14.
  • the lug 50 of the body 34 serves as a drive member of the retaining plate 36 towards the erased position against the action of the biasing spring 56, causing the toggle 40, 42 to break, when the lever 14 reaches the end of the closing stroke (FIG. 3).
  • the bias spring 56 is advantageously formed by a strand of the return spring of the trigger lock.
  • a return spring 58 disposed between the housing 12 and the body 34 opposite the lever 40, biases the lever 14 towards the open position ( Figure 1).
  • the snap closure device 10 has a compact structure thanks to the coaxial arrangement of the accumulator spring 30, the lever 40 and the retaining plate 36 on the axis 38 of the lever 14.
  • the operation of the snap closure device 10 according to the invention is as follows:
  • the retaining plate 36 In the open position of the mechanism (FIG. 1), the retaining plate 36 is in the active locking position by the action of the biasing spring 56, and the link 42 is separated from the boss 48 by a predetermined distance.
  • the link 42 moves in the light 46 until it comes into abutment against the boss 48 of the retaining plate 36.
  • the kinematic chain 16 drives, during this start of the closing stroke, the contact arm 18 in a counterclockwise direction to a stable intermediate position separated from the fixed contact 20 by a small interval "d" having a length of one or a few millimeters. This stable intermediate position of the contact arm 18 corresponds to the position of attachment of the link 42 to the boss 48.
  • the arming of the energy storage spring 30 takes place during the continued pivoting movement of the lever 14 towards the position shown in FIG. 3.
  • the blocking of the rod 42 by the retaining plate 36 hampers the movement of the kinematic connection, and the contact arm 18 remains stationary in the intermediate position of FIG. 2.
  • the unlocking lug 50 drives the retaining plate 36 clockwise of a watch towards the erased position, against the force of the spring 56.
  • the release of the link 42 authorizes the passage of the neutral point of the toggle joint, and the relaxation of the spring 30. All the energy stored in this last, by actuation of the lever 14 is thus returned to the rocker arm 22 of the kinematic link 16, causing a sudden closure of the contacts 19, 20, ( Figure 4).
  • the transmission rod 42 is then positioned at the bottom of the light 46, and the retaining plate 36 remains biased in the position erased by the lug 50.
  • the erasure of the boss 48 then authorizes a manual opening operation of the circuit breaker tor by pivoting the handle 14 anticlockwise towards the position of figure 1.
