Definitions

  • the present invention relates to an electromechanical circuit breaker comprising a housing and a control mechanism with a trigger mechanism able to open polar contacts in response to the implementation of an organ trigger, especially magnetothermal, following an electrical fault, and endowed a rotary knob cooperating with the triggering mechanism and intended for open and close contacts on a voluntary basis.
  • the document FR 2 671 907 shows such a circuit breaker, in which a rotary knob able to take a "on” position and a “off” position presents a toothed crown cooperating with a toothed sector of return which allows a one-to-one cooperation with the trigger mechanism.
  • the rotary knob be placed in response to a trip on fault, in a trip position distinct from the on and off positions, and remains in that position for give the operator a reliable indication.
  • the document FR 2 815 166 describes a circuit breaker equipped with a rigid lever requested by a spring for cooperating with a pin integral with the rotary knob.
  • the device such a circuit breaker then has another purpose, namely to generate a closure fast circuit breaker contacts by introducing a peak of effort during the closing movement.
  • the aim of the invention is to make it more compact and to simplify the arrangements in a circuit breaker mechanism of the type briefly described, to enable at the control knob to take an intermediate trigger position between its on position and its off position.
  • the retaining device of the rotary knob in the position of triggering comprises a torsion spring associated with the circuit breaker housing, in being independent of the trigger mechanism and external to it.
  • the trigger mechanism is thus rid of the button stop function in intermediate release position.
  • housing designates a part main case or a part attached to the front thereof, such as a cover.
  • a rotary member provided with a stop finger is associated with the button, and the torsion spring is disposed on a fixed part of the circuit breaker housing, in presenting a restraining branch.
  • the stop finger cooperates with the branch of restraint to cross it when the button goes from the stop position to the position walk, and to be stopped by it when the trigger mechanism passes from the state to the triggered state.
  • the torsion spring is mounted oscillating about its axis, and has an applicable support branch against two stops of the housing. Attack of the retaining branch by the stop finger is then carried out in a different angular position according to the direction of movement of the button, thanks to the travel allowed by the oscillation of the spring between the two stops. This results in greater ease of operation of the button.
  • the cover can advantageously have a front wall behind which are advantageously formed or arranged the spring bearing and the stops of his support branch.
  • Figure 1 is a schematic perspective view of a circuit breaker according to the invention.
  • Figure 2 illustrates the circuit breaker by a schematic side view.
  • Figure 3 shows front various elements of the circuit breaker and the control knob in the "off” position.
  • Figures 4 to 6 show the control button in various positions, namely respectively a transient position during the motion-on movement, the "on" position and the "tripped” position.
  • the circuit breaker comprises (see FIG. 1) an insulating housing 10 comprising a part rear 10a and a front portion 10b, such as a hood, assembled at the rear. On a front wall 10c of the front part of the hood is arranged a button of control B pivoting about an axis X1. Button B can occupy three positions stable, ie a stop position marked "0", a running position marked "1" and an intermediate trigger position marked "trip".
  • contact bridges 11 which cooperate with fixed contacts 12 to open and close polar paths 13 connected to connection terminals upstream 14 and downstream 15.
  • a trigger mechanism 20 is housed in the housing 10 so as to actuate polar pushers 16 adapted to control the displacement of the bridges of contact.
  • the button B is connected in rotation to a rotary element of axis X1 such that a Ring gear sector 17. Depending on the case, the rotary member 17 is distinct from the button or confused with this one.
  • the crown sector 17 is provided with a radially projecting finger 18 presenting a side a relatively steep side and the other side a slope 18a.
  • Sector 17 meshes with a toothed sector 21 of axis Y perpendicular to that X1 of the button, the sector 21 being linked to a system of levers 22 of the triggering mechanism 20.
  • Magnetic and / or thermal triggers 19 act on the system of levers 22 to cause in case of electrical fault, including overcurrent, the switching of the system 22 and thereby the opening of the contacts.
  • the mechanism of trigger 20 comprises two mounting cheeks 23 which extend into planes perpendicular to the Y axis and which determine between them a compartment relatively flat 20a; the compartment 20a houses the lever system 22 and a trigger spring 24 providing the displacement energy necessary for a actuating member 25 which cooperates with the polar pushers 16.
  • a weak spring 26 for example spiral - used to remind the button at the off position.
  • a restraint device with a force threshold, able to hold the button B in its intermediate position of tripping, is associated with the housing of the circuit breaker, particularly to the front wall 10c of its cover 10b. This device is located according to the invention outside the compartment 20a of the trigger mechanism 20.
  • the stress threshold retainer comprises a torsion spring 30 of axis X2 parallel to the axis X1 of the button.
  • the torsion spring 30 comprises two branches end 31,32 and is mounted floating, that is to say angularly displaceable of way to rotate in a block in a limited manner about the axis X2, on a bearing 33 in protrusion inside the wall 10c.
  • Branch 31 is a restraining branch oblique capable of flexing angularly and intended to cooperate with the radial finger 18 of the ring gear 17.
  • the branch 32 of the spring is a support branch which can be applied in a clockwise direction (direction of movement of the "stop” "running") against a stop 34 and counterclockwise against a stop 35. stops 34 and 35 are angularly offset and provided as elements of the front wall 10c or a rim of this wall.
  • the torque due to the spring 30 is greater than that due to the return spring 26 of the button, but less than that due to the sum of the the forces produced by the release spring 24 and the return spring 26.
  • FIGS. 3 to 6 respectively show the situation of various parts in the off state, in an intermediate state between the off state and the on state, in the state walk and in the triggered state.
  • the finger 18 and / or the branch 31 of the spring has a slope facilitating the crossing the end of the branch by the finger 18 when the button B is brought from the off position to the on position. It is thus represented in FIG. the slope 18a already described and provided on the leading edge of the finger 18.
