Definitions

  • the present invention relates to an improvement to circuit breakers or differential circuit breakers of the type comprising, in a generally modular housing, two or more connection terminals, one or more movable contacts, one or more fixed components, a locking mechanism means allowing, from an actuating member such as for example a lever or a push button, to switch the movable contact between an open position remote from the fixed contact and a close position close to the fixed contact, and vice- vice versa, and disjunction means, for example of the magnetothermal type, comprising a disjunction coil with a movable core returned by spring and carrying a striker, and a disjunction bimetallic strip, the mechanism being arranged so that in the contact closed position , it can be released and quickly opened by the action of any of the means of disjunction.
  • an actuating member such as for example a lever or a push button
  • a device of this kind is for example described in French patent application FR-A-2,522,931.
  • Patent EP-A-0.105.945 describes a device in which a lever is pivoted on the same axis as the contact carrier. This part can be actuated by a movable armature of a disjunction coil. It is normally pushed back in the locking direction by a helical spring carried by the contact carrier and its locking arm has a ratchet surface substantially perpendicular to the radius coming from its articulation point to hold the end of the rod against a surface. of the contact carrier. The pawl surface is opposed to the upward movement of the rod axis. It thus frees the connecting rod in the event of tripping.
  • Patent FR-A-2,605,454 describes a mechanism using three parts, namely a contact carrier, a plate articulated around the same axis as the contact carrier and a trigger lever.
  • This plate constitutes an additional part interposed between the link and the contact carrier, which requires the interposition, between the plate and the contact carrier, of a powerful spring pushing the contact carrier in the direction of contact and, in the direction reverse, the plate towards the rod on which it exerts the force transmitted by the spring. It is in fact the trigger lever which plays the role of pawl, the plate playing the role of a substitute for the contact carrier. Furthermore, the additional spring introduced between the plate and the contact carrier always exerts a maximum force. In addition, this device is imprecise in its positioning.
  • the present invention proposes to improve such devices in particular at the level of their lock mechanism.
  • Another object of the invention is to provide such an apparatus, the mechanism of which can be mounted both manually and automatically.
  • Another object of the invention is to provide, for such an apparatus, an extremely compact mechanism releasing a large volume in the housing of the apparatus and allowing large breaking chambers and a high breaking capacity, for example from 10,000 to 15,000 amps.
  • Another objective of the invention is to produce such a device at low cost price.
  • the subject of the invention is an apparatus such as a circuit breaker or a differential circuit breaker, arranged in a modular type housing, having two or more connection terminals, at least one fixed contact and at least one movable contact capable of approaching and s' away from the fixed contact, a toggle mechanism actuated by an operating member and comprising a link articulated around a first axis on the operating member and capable of being driven by the operating member, a rotary contact holder in which at least one movable contact is pivoted and having a bearing surface against which the second end of the link is applied for driving the rotary contact carrier in the direction of contact closure against the effect of a powerful return spring , and means capable of being actuated by a disjunction means to authorize the breaking of the toggle joint and the separation of the movable contact from the fixed contact, characterized in that said means capable of being actuated by the disjunction means comprise at least one part articulated on the rotary contact holder about an axis eccentric with respect to the axis of rotation of said rotary contact
  • the eccentricity of the axis of said articulated part facilitates its release relative to the link when the disjunction means are actuated.
  • said part forms a trigger pivoting around said eccentric axis of the contact carrier and having a part capable, during its rotation, of driving the rod in rotation around its first axis to release the second end of the link far from the contact carrier's reach.
  • the trigger when driven from the disjunction means, it moves the link away from the range of the contact carrier, carried substantially perpendicular to the direction of the force transmitted to the link when the toggle is braced.
  • said part is a pawl pivoting around said eccentric axis on the contact carrier and having a surface allowing, in addition to the range of the contact carrier, to maintain said second end of the rod in abutment on said carried in the closed contact position and allowing the spontaneous escape of said second rod end far from the range of the contact carrier when said pawl is actuated by the disjunction means.
  • the device according to the invention simultaneously comprises a trigger and a pawl as defined above.
  • said trigger and said pawl are preferably made in one piece having a pawl surface in contact with said second end of the rod applied against the bearing surface of the contact carrier in the closed position, and a trigger surface coming into contact with said rod after the surface of the pawl has been moved away to allow escape.
  • This arrangement ensures safe operation of the lock mechanism when the tripping means are triggered. If the distance from the pawl surface has not been accompanied by the release of the link and the tilting of the contact carrier, for example due to the blocking of certain parts by deformation of material, the trigger comes, in good time, positively release the end of the link away from the contact carrier.
  • the trigger is produced in the form of a fork-shaped part recalled around its axis by a spring in the direction of holding the rod, the arms of said trigger having oblong slots in which the end portions can move. of the link.
  • the range of the contact carrier, against which the second end of the link is applied is inclined in the direction favoring the escape of the pawl out of the range of the contact carrier recalled by its spring contact, the pawl, pivoted on the contact carrier being recalled with a small force towards it, having a rod retaining surface oriented perpendicular to the geometric radius joining said surface to the pivot axis of the pawl on the holder contact, so that a slight force on the pawl in the direction tending to move the pawl away from the contact carrier is sufficient to release the link which is then free to escape from the ramp under the action generated by the contact spring , in the direction of contact opening, of the contact spring at the inclined surface of the contact carrier surface.
