Definitions

  • the present invention relates to a lock mechanism for a circuit breaker with a magneto-thermal circuit breaker or similar device, in particular for a phase and neutral circuit breaker. It also relates to circuit breakers fitted with this mechanism.
  • Line protection circuit breakers include, in a housing, a circuit extending between two terminals and include a thermal trip bimetal for protection of the line against overloads and an electromagnetic tripping device comprising a coil with an associated plunger core to a striker, to ensure, in the event of a short circuit, the tripping by opening of a movable contact cooperating with one or more fixed contacts.
  • the phase and neutral circuit breakers comprise, in addition to the phase stage as described, a neutral stage with fixed and mobile contacts, the mobile neutral contact being actuated jointly with the mobile phase contact.
  • the actuation of the movable contact is generally carried out by a locking mechanism, of the toggle type, usually comprising an operating member with a lever type lever actuated manually and causing a rod tending to push back a pivoting contact carrier which carries one or several movable contacts to bring them each in pressure contact against a fixed contact, up to a position in which the return in the opposite direction, towards the contact opening, is normally prevented by a pawl preventing the link, by pressing the toggle joint on the contact carrier, from escaping and to release this one.
  • Manual opening is carried out by operating the lever in the opposite direction.
  • the disjunction is generally caused by action of the bimetallic strip or the striker of the coil against a trigger lever so as to cause the release of the pawl and therefore the escape of the rod, and, in the case of magnetic disjunction, the Forced opening of the contact carrier.
  • the contact carrier return spring also serves to maintain contact pressure.
  • the present invention proposes to remedy these drawbacks and to provide a lock mechanism suitable for automated mounting in a circuit breaker, both in the case of a simple circuit breaker and in the case of a phase and neutral circuit breaker. .
  • Another object of the invention is to provide a lock mechanism making it possible, in the case of a phase and neutral circuit breaker, to assign independent contact pressures to the movable phase and neutral contacts.
  • Another object of the invention is to provide a particularly simple, inexpensive lock mechanism that takes up as little space as possible.
  • yet another objective is to be able to assemble the devices according to the invention along a single mounting axis.
  • the subject of the invention is therefore a circuit breaker lock mechanism, of the type comprising an operating member provided with an actuating handle and normally pushed back into position corresponding to the opening of the contacts of the circuit breaker by a return spring, a rod, one end of which is mounted eccentrically on the operating member, a contact carrier pivoting about an axis and having a ramp against which can come to bear and brace the other end of the rod , at minus one movable contact mounted on the pivot axis of the contact carrier so as to be able to pivot slightly relative to the latter to exert contact pressure on a fixed contact, a power spring urging the contact carrier and preventing the exhaust of the link when it is braced against the contact carrier, the pawl being associated with a triggering means capable, when it is actuated, of causing the pawl to tip over and the release of the link, and possibly to drive the contact carrier in the open position for forced removal of the movable contact, characterized in that the or each movable contact is held angularly on the
  • the great novelty consists in the fact that it is no longer necessary to mount the lock mechanism as a sub-assembly ready to be assembled, since the two supports of the spring are on the movable contact. This means that this torsion type spring can be mounted on the movable contact without the contact carrier being attached thereto. And therefore, the automation of the various elements of the moving assembly can be total.
  • the elastic return member is a spring of the pin type.
  • the pawl and the triggering means are made in one piece, in particular in molded plastic, and are pivoted on the pivot axis of the contact carrier (s).
  • the contact carrier preferably has at least one pivot on which the pawl-tripping means assembly is placed and a movable contact with its elastic contact member.
  • the contact carrier has a recess whose median axis is aligned with that of the pivot and by which the contact carrier can be pivotally placed on a shaft end carried by the circuit breaker housing and capable of receiving the other movable contact and its elastic contact member.
  • the contact carrier can also include another pivot for supporting a movable contact and its elastic contact member.
  • the contact holder preferably being made of molded plastic, the pivot (s) can advantageously come from molding. However, it is understood that one can also use added pivots.
  • the two elastic contact members can be of different strengths.
  • the pawl and the triggering means are preferably made in one piece from molded plastic.
  • the rearming of the pawl, that is to say its return to the closed position, can advantageously be ensured by the return spring of the operating member.
  • the contact carrier is made of molded plastic and has a transverse head serving to support the return spring of the contact carrier, separated from the body of the contact carrier by a light in V having said ramp-up ramp, and the body of the contact carrier has, on its lateral faces, the pivot and the recess respectively, as well as each time a finger located closer to the head than the pivot or the recess and, with respect to the latter, opposite the operating member.
  • identical mobile contacts can be used, formed from metal parts with flat cross sections and comprising, in an enlarged part, a notch in the form of a secondary quasi-orifice engaging around the aforesaid finger and a lateral lug forming a fulcrum for the elastic contact member, the enlarged part being extended by an elongated part having the actual electrical contact point, and, on the opposite edge of said elongated part, a notch forming the second point of support for the elastic contact member.
  • the main opening of the enlarged part is provided oblong, so that the elastic members perfectly play their role of increasing the pressure of the movable contact on the fixed contact.
  • the invention also relates to circuit breakers comprising such a lock mechanism.
  • this lock mechanism lends itself perfectly to automated mounting piece by piece in a circuit breaker box, as is moreover apparent from the part of the description which follows and which relates to an mounting method.
  • a mechanism could also be pre-assembled, in particular thanks to the use of a single added pivot axis.
  • FIGS. 1 and 2 are partial left views of the interior of an apparatus according to the invention, and in FIG. 3, the right side of the sheet corresponds to the right side of the case, face 9.
  • phase and neutral terminals are respectively shifted in height, for the purpose of polarization.
  • the circuit breaker further comprises the aforesaid operating member 5 with its actuating handle 5a, intended to act, by means of a link 39, on the lock mechanism 40 which mainly comprises a movable contact carrier 41 with a toggle joint device, cooperating with the link 39 and with a pawl 42 integral with a trigger lever 43, with the lock mechanism 40, which is biased by the coil 33 and by the bimetallic strip 27, in the latter case via a coach 44.
  • the left and right half-shells and the spacer are specific to the chosen configuration, neutral on the left or neutral on the right.
  • a left half-shell 10 ' is used for the neutral side, a spacer 12' and a right half-shell 11 'for the phase stage.
  • this lock mechanism 40 generally comprises the movable contacts and the operating member 5 with its actuation handle 5a and its spring. recall 96.
  • the operating member has a pivot axis 45 and, laterally, an extension 46 pierced with a passage 47 parallel to said pivot axis 46 and in which one of the two end branches of the link can be articulated 39, which has a U shape.
  • the return spring 96 has a first branch 96a secured to the operating member and a second branch 96b intended to bear against the pawl 42 to ensure rearming as will be seen below. .
  • the mechanism also includes the contact carrier 41 made of molded insulating material and having an upper transverse head 48 provided, opposite the operating member 5, with a bearing 49 serving to support a powerful return spring 50 of the contact carrier 41 in the open position of the contacts.
  • the head 48 has a part 48a, connecting to the body 55 of the contact carrier 41 and having an elongated lumen 51, substantially V-shaped in cross section, the shape of which will appear better in FIGS. 11 and 12, and which receives the second end arm 39a of the link.
  • the light 51 comprises a first part 52 which is substantially horizontal when the device is placed on its base 1 (see FIGS.
  • the body 55 of the contact carrier 41 has on one side a cylindrical protuberance 56 forming a pivot (hereinafter pivot 56), which is characterized by two parts of different diameters, namely a part 57 of large diameter, body side 55, and an outer part 58, of smaller diameter.
  • This pivot 56 is hollow and therefore has a first outer section 60 of large diameter extending by a second inner section 62, of smaller diameter.
  • the body 55 has laterally two arcuate shoulders 63, symmetrical to one another, one of which overhangs the part 58 of the pivot 56 and which both overhang fingers 64 also provided on each of the sides of the body 55
  • the upper surface of the body 55 forms the transition surface between the two parts 52 and 53 of the lumen 51, with the thrust surface 54. This surface is made to allow passage and movement of the end 39a of the link.
  • the mechanism further comprises a molded plastic part which joins the pawl 42 and the trigger lever 43 and which has, on one of its faces and transverse to it, a cylinder trunk 65 whose light s' fits on the part 57 of the pivot 56 for pivoting mounting on the contact carrier 41.
  • the pawl 42 formed by a protruding rim on the same side as the cylinder trunk 65, is intended to normally block the end 39a of the link 39 in the inclined part 53 of the light 51 and it can be erased in order to let escape the said rod end 39a in the part 52 of the light 51, when the magnetic disjunction means are actuated or under the influence of the bimetallic strip.
  • the return spring 96 then allows the pawl 42 to be reset under the action of the branch 96b when, starting from the disjunction position, the lever 5a is brought back trigonometrically to the "On" position (FIG. 15).
  • the trigger lever 43 has an intermediate surface 66 intended to be struck by the percussion rod or striker of the electromagnetic coil 33 and, at its end opposite to the previous one, a spout 67 mechanically connecting the bimetallic strip 27 to the lever 43 via the driver 44 ( Figures 3 and 4) to ensure thermal disjunction.
  • the movable contacts 17 and 29, which can be neutral or phase depending on the embodiment of the circuit breaker, are identical and have, in a head 68, a main orifice 69, which is slightly oblong, intended to come on the axis pivoting mechanism, that is to say, in the embodiment described and shown ( Figures 7, 9,10), either on the part 58 of the pivot 56 for the left movable contact, or on a tip shaft carried by a housing half-shell and coming to be placed in the recess 59 of the contact carrier 41, for the right movable contact.
  • a notch in the form of a quasi-orifice 70 is also provided in the head 68 and is intended to be engaged on the finger 64 of the contact carrier 41, a finger which actually acts as an axis of articulation of the movable contact when one arrives in the contact position. It should indeed be noted that the pivoting axis of the movable contacts is different from that of the lock, for reasons considered later.
  • the head 68 is extended by an elongated part 72 having the actual electrical contact point, reference 73, and, on the side opposite this last, a notch 74. Finally, on its edge opposite to said elongated part 72, the head has a lateral lug 71 coming from folding.
  • Each movable contact 17, 29 is associated with a powerful contact spring 76, with a turn, having two branches 77, 78 forming at rest a slightly obtuse angle, the branch 77 further comprising an end 79 folded at right angles to the outside. .
  • This spring is shaped so as to normally maintain the movable contact on its axis and, in the closed position, to ensure the contact pressure on the corresponding fixed contact.
  • the turn of the spring 76 is placed around the axis (pivot 56 or end of the shaft of the housing), while the branch 77, by its end 79, and the branch 78 engage in the notches 74 and against the lugs 71, respectively.
  • the establishment of the spring is done under stress by bringing the two branches 77,78 towards one another.
  • the actuator 5 no longer being entirely in the "Stop" position, but in an intermediate position, shown in FIG. 13, the open contact position is guaranteed by the action in direct trigonometric direction of the powerful spring 50 on the assembly constituted by the contact carrier 41, the movable contacts 17 and 29 and the pawl 42.
  • the free end 39a of the rod 39 is then held by the pawl 42 against the inclined thrust surface 54.
  • the action of the pawl 42 is possible because the spring 96 brings it closer to the contact carrier.
  • This wear stroke is in particular intended to compensate for the play which would possibly come from contact wear, and which would create contact problems, making the circuit breaker much less reliable.
