Definitions

  • the invention therefore proposes to provide an apparatus in which rotating parts will be used wherever relatively large transmissions of force occur which may consequently cause abnormal wear, while reducing the size of an apparatus where displacements or races of certain parts take on relatively large values; these important races will be necessary on the one hand because of the fact that certain actions are communicated by user, and that their accomplishment will have to be clearly perceptible by this one, and on the other hand because of the concern to make each state clearly visible what can the device take; moreover, the energies necessary for the very rapid setting in motion of the parts concerned at the time of a trigger being lower as their masses are reduced, the significant reduction in dimensions will result here in an improvement in the response time of the 'apparatus.
  • the transimission member has between two parallel plates a series of superimposed cam surfaces which are able to cooperate with the locking lever and with a common part taking the form of 'a pivoting lever capable of cooperating with a pivoting lock, this member, this locking lever and this common part having pivot axes parallel to each other and perpendicular to the plates between which they are placed.
  • switches with manual control and automatic opening in which the axes of the movable rotary parts, comprising in particular locking and resetting triggering members, are placed parallel to each other and are pivoted between two plates; the aim sought here is generally to obtain reduced transverse dimensions with a view to achieving a grouping side by side of numerous devices of small thickness which is made possible thanks to a short separation distance of the plates, which on the other hand results in an increase in the surface thereof; moreover, in these known devices, the position of the manual control member, corresponding to the triggering state, is not clearly separated from the open and closed positions so that erroneous information can be perceived by the users.
  • the invention also aims to obtain remote control operation which is in its results as close as possible to that which is performed by an operator, while using a sequence different operations so as to reduce the travel of the parts directly associated with a small electric motor intended for these maneuvers; the achievement of the result was notably achieved by discarding the traditional solution of a reset which is directly associated with the manual control button.
  • FIG. 1 The block diagram of a switch device in an insulating box 20 having power contacts, the closing and opening of which can be controlled remotely, as is the case with contactors, and furthermore presenting means automatic opening which act when appear on the power circuit which supplies a load with overloads of different kinds, is illustrated in Figure 1.
  • An electromagnet 1 having a coil 3 placed in series with a safety switch 4 in the control circuit 7 and between the control terminals 5 and 6, attracts a frame 29 against the action of a return spring 36.
  • the power circuit 8 of the device placed between the power terminals 9 and 10, comprises the switch 2, a coil 11 with which is associated a magnetic striker 28, a magnetic coil 13 with which is associated a pallet 34 and a bimetallic strip 14. It should be understood that several power circuits, for example three, can be arranged in the apparatus for supplying polyphase loads. When frank short-circuit currents appear in circuit 8, the striker 28 lifts the movable contact 2a by an instantaneous action "a" and the latter remains hooked in the open position behind a latch 28a.
  • a displacement undergone by the bolt on this occasion transmits an action "q" to a first device with abrupt release 17.
  • the bimetallic strip 14 deforms and communicates an action "c" to the second mechanism 19.
  • the first device 17 is therefore released or triggered when one of three abnormal overloads appears in the circuit (10, 9, 8, 8a).
  • the device 17 When the device 17 is triggered, it in turn produces an action "p" which is applied to a third device with abrupt trigger 31. The latter then transmits an abrupt action ° e "to open the switch 4, and the electro -magnet 1 is de-energized.
  • the first and third devices 17 respectively 31 cooperate by actions “m” and “m” respectively j and j with a rotary transmission member 32, which is integral with a local manual control button 18 which can move in front of a ladder 33 comprising in this order four positions "F", “D”, “ O “and” R ".
  • the member 32 is associated with a return spring 35 which tends to move it in a direction K.
  • switch 2 will be closed when a suitable voltage is applied between terminals 5 and 6 to supply the load.
  • the action “m” then causes the action “e” which opens the switch 4 and releases the member 32, while the action “j” places in the path followed by this member a stop capable of stopping the latter in an automatic opening position of switch 2 following the appearance of a fault.
  • the user having to search for the causes of the appearance of this fault, must then place the button 18 in the stable voluntary open position "O" defined above.
  • the device When the fault has been located, and its cause has been ruled out, the device is put back into service by a manual action of the operator exerted on the button 18 to bring it first into the position "R" reset unstable.
  • the mechanism 100 which performs the functions illustrated in FIG. 1 by the references 4, 17, 18, 31, 32, 33, 35 is represented in FIG. 2 in a section passing through the axis XX 'of the rotary control button 18
  • This button is fitted to a prismatic shaft 40, for example having a square section, one edge of which has been chamfered in order to avoid possible orientation errors.
  • This shaft which passes through the rotary part 32 to drive it, is pivoted on the one hand at a lower end 40 'in a bore 42 of a lower plate 44, and on the other hand in an upper region thanks to a cylindrical bearing 32 'of this member 32 which is pivoted in a bore 41 of an upper plate 43 parallel to the previous one.
  • the transmission member 32 has in three planes P1, P2, P3, parallel between them and perpendicular to the axis XX ', cam surfaces 45, 46, 47 whose function will be specified later.
  • a metal part 52 integral with this member 32 carries a finger 51 which cooperates with one end 50 of a helical spring working in torsion, and of which another end 49 cooperates with a support 57 of the plate 44, see also FIG. 3; this spring communicates to the member 32 a couple of counterclockwise direction K.
  • This locking lever 55 has two opposite arms 55a, 55b, one of which 55a carries a support 61 and is associated with a return spring 58 which communicates to it a torque of direction K; the other arm 55b carries on the one hand, around a articulation 60 a pawl 59 which is subjected to a direction torque K provided by a compression spring 69 placed between an arm 68 of this pawl and the lever 55, and on the other hand has a percussion surface 76.
  • Another arm 66 of the pawl has a hook represented for example by a cylindrical stud 67 parallel to XX ′ and placed in the plane P 2 .
  • a insulating contact lever 62 having an end 63 which can separate a movable contact 64 from a fixed contact 65, these two contacts belonging to the safety switch 4.
  • a helical spring 73 whose turns are placed around the rod 53 has an end 73 which is linked at a point 74 of the contact lever, and a free end 75; this spring, which is placed in elastic torsional stress between point 74 and a stop 130 of the contact lever, is therefore free to orient itself around the rod 53, with the contact lever 63 while being limited in displacement by the support 61 that the lever 55 can cause to cooperate with the contact lever
  • the cam 46 of the transmission member 32 has in the plane P2 opposite the hook 67 a substantially radial holding surface 70, an internal cylindrical bearing surface 93 and an external cylindrical bearing surface 71.
  • the trigger lever 56 which is subjected to a counterclockwise torque K by the tension spring 79 bears in inactive position 1, by means of a tooth 80 placed at its periphery, against a spout 81 belonging to a lock 82 which can tilt around an axis parallel to ZZ '.
  • This trigger lever also has a hammer 91 placed in the plane P 2 opposite the percussion surface 76, an abutment surface 92 placed opposite the surface 93 and a first cooperating surface 94.
  • the lock 82 receives a clockwise torque L from a compression spring 84, and has two arms 85 and 86 which can receive thrusts q and r transmitted respectively by a folded portion 89 of a first drawer 87 (partially shown in dotted lines due to its location under the plate 44) and respectively by one end 90 of a second drawer 88, these two drawers moving parallel to the planes P1, P2, P3.
  • a push q or a push r exerted on the lock 82 produces a counterclockwise rotation of the latter which releases the beak 81 from the tooth 80 and allows the trigger lever 56 to pivot counterclockwise under the action of the spring 79.
  • This movement causes the hammer 91 to strike the percussion surface 76 and produces a clockwise rotation L of the locking lever 55, the support 61 of which causes the contact lever 62 to move in the same direction in order to open the switch 4, while the hook 67 disengages from the holding surface 70 to release the transmission member 32.
  • the trigger lever 56 stops in a working position T for which the abutment surface 92 meets the surface d support 93, see figure 8.
  • This state triggers the mechanism, which can only be obtained if actions q or r consecutive to overloads of different natures have appeared, is also signaled externally by a display device 21 if the action q has been decisive thanks to the displacement a witness 23 carried by a part 25 which is movable around the axis XX 'and which is associated with a tab 97a of the drawer 87 and with a return spring 24.
  • This signaling device 21 places the indicator 23 opposite an opening 22 of the housing 20 of the apparatus, see FIG. 3, and therefore signals the appearance of a frank short-circuit.
  • the tooth 80 appears opposite the beak 81 and, if the actions q or r are no longer present, this engages behind the tooth 80 so as to maintain the release lever in position I. Due to the torque imparted by the spring 35, the holding surface 70 continues to bear against the stop surface 94 and provides the parts 18 and 32 with a stable position d 'opening 0.
  • Such a reset action which is carried out by an additional manual rotation of the control button 18 in direction K, going from position 0 to position R of button 18 (see FIG. 6), begins when, in this position 0, a reset surface 77 belonging to the cam 47 of the transmission member 32 and is finding next to an extension 78 of the trigger lever 56 meets the latter to push it clockwise L until the trigger lever 56 reaches a position A visible in Figure 10. So that the continuity of the movement from D to R via 0 is ensured, surfaces 70 and 77 and surfaces 94 and 78 are offset by angular values alpha and beta respectively, see Figure 5b, which produce a meshing effect.
  • the trigger lever 56 also plays the role of a reset lever thanks to two lugs 95 and 96 which push portions 97b and 98 belonging to the two drawers 87 and 88 respectively, see Figures 10 and 11 Found in FIG. 1 under the designation q and the corresponding reset actions which are applied to the detector devices 28a and 19.
  • the lever 56 is therefore a common triggering and reset piece.
  • the transmission member 32 returns by itself in the direction L towards the position 0 under the effect of the spring 35, which gives an unstable character to the position R.
  • a remote reset device 101 which is for example housed in an annex box 160 and which will have to carry out, in the event of automatic triggering, a reset operation of the snap devices 17, 31 and 19; on the one hand, this operation should only be possible if, after an automatic triggering, the snap device 17 is itself in the condition of being reset; this possible rearming state is acquired if the snap device 19 does not permanently deliver an action r "caused by a bimetallic strip 14 still hot.
  • This operation must be prohibited or at least a corresponding information must be provided in order to avoid it, if the mechanism is in a voluntary open position 0, which has been given to it by a manual action exerted by an operator placed near the device; such a voluntary opening may indeed have been decided by this operator to carry out the inspection of a machine powered by the device and this without the knowledge of another person placed at a distance, so that a rearmament remotely controlled by this person could have serious consequences, either due to the restoration of the voltage on the supply line, or due to the start of a process in which not all devices are in working order.
  • the remote reset device mainly comprises (see FIGS. 12 and 13), a small electric motor 102, a speed reducer 103, a helical or spiral cocking cam 104, an cocking button 105, biased against the cam by a spring 105a, and an internal electrical circuit 106 comprising in the housing 160 three own terminals 107, 108, 109, two switches 112, 113 and of course the motor 102.
  • the complete control circuit further comprises an external remote control switch 111 and two terminals for connection to the network 114,115.
  • the self-power switch 112 is placed in parallel on it between a terminal 116 of the motor and a first network terminal 114, the current return being effected between a second motor terminal 117 and the network terminal 115.
  • This switch 112 replaces switch 111 as soon as the arming push-button 105 has started to move and remains closed until the cam 104 having, for example, made a full revolution returns to its starting position for which the switch 112 is open, which stops the engine.
  • the authorization switch 113 which will only be closed for this tripping position is placed between the terminal 116 of the motor. and the switch 111.
  • This authorization switch is actuated by a pusher 136 which cooperates, as will be seen below, with a particular part of the mechanism 100.
  • a drive part taking the form of a slider 118 has therefore been associated with the mechanism 100 which itself comprises organs or has special measures intended to establish the necessary cooperation with this slider.
  • the drive part 118 is formed by a slide movable along an axis QQ 'which is parallel to the plates 43, 44 and therefore perpendicular to the axes XX', YY ', ZZ'.
  • This slide which could if necessary be replaced by a pivoting part having a neighboring movement, has an elongated opening 119 which is crossed with a small clearance by the pivot 54 of the part 56 and an end 120, by which the guidance is carried out in translation.
  • This slide has, in addition, first, second and third support points 121, respectively 122, respectively 123 and a second end 124 which is opposite to these support points.
  • This slide is held against a stop 125 of the housing by a return spring 126 which places the end 124 opposite an opening 127 of the housing 20 so as to be able to cooperate with the end 134 of the arming push-button 105.
  • the transmission part 32 has, in an upper region 128, through which passes the plane P 1 adjacent to the plate 43 and containing the slide 118, a thrust surface 131 belonging to a cam 45 whose angular position is offset by an angle phi with respect to the surface 70 see Figures 2 and 14; this surface 131 is placed opposite the fulcrum 121 and is separated from it by a certain distance d 1 when the transmission part is in position D and that the slide 118 is against the stop 125 in a rest position S o shown in dotted lines in Figure 15a.
  • the second fulcrum 122 which here belongs to an inclined ramp 122a, is placed opposite a second thrust surface 132 represented by the end 75 of the spring 73; a distance d 2 separates this fulcrum 122 and this surface 132 when, the part 32 being in position D the locking lever 55 is in position B, and that the contact lever 62 is in position G.
  • the third support point 123 is placed opposite a third support surface 133 which is carried by the stud 95 of the common triggering and arming lever 56, in a region thereof, opposite the tab. 97, see also FIGS. 10 and 11, and is separated from this surface by a distance d 4 when the triggering and arming lever 56 is in its working position T and the slide 118 is in the position S o , see figure 15a.
  • the slider 118 will move the member 32 directly to the position F and the part 56 to the position A, this position being further from the position T that position 1 for which the tooth 80 passes in front of the latch 82.
  • the slide 118 passes for example first to the point such as 5, where the stops 95, 96 of the common part 56 meet the drawers 97b, 87 and 98, 88 to push them back and reset the devices 19 and 28a, then at point S 3 when the tooth 80 of the part 56 is opposite the beak 81, subsequently at point S 4 when the hook 67 after having slipped against the surface 71 is opposite the surface 70, and finally at point S 5 where the part 56 is in position A.
  • this closure is made impossible by the cooperation of the surfaces and support points 132 and 122.
  • This cooperation which begins sufficiently early for example at point S 2 of the path of the slide 118 has a property of limiting the stroke of the contact lever 62 which is obtained thanks to the elasticity of the spring 73 and thanks to the presence on the housing 20 of a stop such as 12a or 12b, see FIG. 15e.
  • This elasticity and these stops are capable of preventing excessive deformation of the movable contact 64 and of stopping the lever 63 in the H position, independently of the total travel of the slide 118.
  • the slide 118 is at this point in point 5 9 for which the switch 4 which was still open, sees its opening confirmed by the tilting of the lever 55, while the member 32 returns to its corresponding trigger position D.
