  • the operating handle can also be replaced by an electric motor associated with a reduction gear to constitute an electric control unit.
  • most of the elements of this operating mechanism are arranged on a support 27.
  • the rotary drive means 25, the operating mechanism and its support 27 are described in more detailed manner further on in the following.
  • the control unit 1 is assembled on the front panel 3 by means of assembly means integrated in said control unit.
  • the assembly means are designed to collaborate with the first surface 21 and the second surface 22 of the protuberant part 13. More precisely, the assembly means comprise two first pressing parts 31 securedly united to the control unit 1 and designed to press on the first surface 21 of the protuberant part 13.
  • the assembly means further comprise two second pressing parts 32 securedly united to the control unit 1 and designed to press on the second surface 22 of the protuberant part 13.
  • the two first pressing parts 31 and the two second pressing parts 32 can all four be seen in figure 4 .
  • the two first pressing parts 31 are fitted substantially facing the respective two second pressing parts 32.
  • the support 27 of the operating mechanism extends between two parallel lateral mounting plates 35 provided with notches 37, to accommodate the protuberant part 13 of the insulating case. More precisely, as can be seen in figure 1 , the support 27 is fixed on the mounting plates 35 by means of inserts 36, 39 of said support embedded in embedment holes 44, 46 of said mounting plates. These mounting plates 35 can also be qualified as flange-plates.
  • the mounting plates 35 are substantially parallel to the side main panels of the circuit breaker 5.
  • the first pressing parts 31 of the assembly means are arranged on the notches 37.
  • the second pressing elements 32 of the assembly means are for their part formed in a part of the support.
  • the notches 37 of the mounting plates 35 present a shape enabling the protuberant part 13 of the insulating case to be accommodated only when the control unit 1 is fitted the right way on the circuit breaker 5.
  • the mounting plates present a rim 38 which comes up against the stop formed by the hand lever 15 of the circuit breaker 5 if the control unit 1 is not fitted correctly on said circuit breaker, thereby preventing fitting of said control unit.
  • This shape of the notches 37, and in particular the rims 38 acts as error prevention means to help the fitter assemble the control unit 1 correctly on the circuit breaker 5.
  • the operating mechanism support 27 is formed in a single mechanical part, i.e. a cut and folded metal sheet.
  • the second pressing part 32 is mounted on first flexible means.
  • the first flexible means are formed by an ear 41 of said support 27, the free end of said ear supporting the second pressing part.
  • the inserts 36 of the support 27 arranged near the ear 41 are embedded in the corresponding embedment holes 44 of the mounting plates 35 with a clearance allowing displacement, whereas the other inserts 39 of said support are fitted with limited clearance in their respective embedment holes 46.
  • These first flexible means 41 enable any relative movement of said control unit 1 with respect to the electric switchgear apparatus 5 to be taken up.
  • the first flexible means 41 prevent nuisance tripping of said circuit breaker which might have been caused in particular by said control unit. They also facilitate assembly or fitting of the control unit 1 on the circuit breaker 5.
  • the material of the support 27 is chosen such as to make the ear 41 sufficiently flexible to absorb any relative movement of the control unit 1 with respect to the circuit breaker 5, in particular when the rotary handle of said control unit 1 is operated.
  • the material of the support 27 is in this case steel. The presence of these first flexible means prevents the circuit breaker from being damaged following operation of the handle of the control unit 1.
  • the assembly means of the control unit 1 comprise two first stops 42 securedly united to said control unit and fitted respectively facing said two first pressing parts 31. More precisely, the first stops are arranged on the notches 37 of the mounting plates 35. These first stops 42 are designed to press on the second surface 22 of the protuberant part 13 of the circuit breaker 5 so as to limit any relative movement of said control unit with respect to said circuit breaker when the handle of the control unit is operated. The presence of these first stops 42 enables a relative movement of the control unit 1 with respect to the circuit breaker 5, said control unit being held secure on said circuit breaker by the first and second pressing parts 31, 32.
  • the second pressing parts 32 press on the second surface 22 of the protuberant part of the circuit breaker 5, whereas the first stops 42 are slightly laid back with respect to said second surface.
  • the extent of this lay-back of the first stops 42 with respect to said second surface 22 is a few tenths of a millimeter and is therefore hardly visible. Operation of the control unit handle can lead to a displacement of the control unit 1 absorbed by the first flexible means 41 until at least one of the first stops 42 comes and presses on the second surface 22 of the protuberant part of the circuit breaker 5.
  • the two first pressing parts 31 are fitted respectively facing the two second pressing parts 32 and respectively facing the two first stops 42. In this way, when rotation of the front operating handle takes place in one direction or the other, one or the other of the first stops presses on the second surface 22 of the circuit breaker 5.
  • control unit comprises another support 28 represented in figure 9 and replacing the support 27.
  • at least a first pressing part 48 is also fitted on second flexible means for example formed by a second ear 50 of the support 28 substantially parallel to the ear 41.
  • assembly means comprise two second stops 31 securedly united to the control unit. These second stops 31, like the first stops, are arranged on the notches of the mounting plates and are arranged so as to press on the first surface 21 of the protuberant part 13 of the circuit breaker 5. These second stops 31 in fact correspond to the pressing parts referenced 31 of the embodiment represented in figures 1 to 8 .
  • the second flexible ear 50 When fitting is performed, the second flexible ear 50 thus prevents the second stops 31 from rubbing on the first surface 21 of the case and from catching on said first surface 21 of the case which is generally made from plastic. This second flexible ear 50 also allows lateral sliding to facilitate positioning of the control unit on the circuit breaker.
  • the assembly means of the control unit 1 further comprise a securing system enabling the control unit 1 to be fixed on the insulating case of the circuit breaker 5.
  • This securing system comprises two securing slides 51, 52 to secure the control unit 1 on respectively one and the other of the connection panels 9 of the insulating case.
  • Each securing slide 51, 52 is provided with at least one latch 53, 54 designed to be inserted in a hole arranged on one and the other of the connection panels 9.
  • the part of the latch 53, 54 that is designed to be inserted in the opening of one or the other of the connection panels 9 can present a cross-section that increases between its free end and its base so as to perform securing as said latch progressively enters the opening.
  • the securing slide 51 comprises two latches 53
  • the securing slide 52 only comprises a single latch 54.
  • This single latch 54 enables connection with a differential unit used as an accessory of the circuit breaker 5.
  • the securing system further comprises two securing supports 56, 57 on which one and the other of the securing slides 51, 52 are respectively mounted. Each of these securing supports 56, 57 extends between the two mounting plates 35 on which it is fixed.
  • the securing supports 56, 57 present the form of a bracket and are in this case made from plastic.
  • Each of these securing supports 56, 57 comprises slide racks 59 on which the securing slide 51, 52 mounted on said securing support slides.
  • Each of these securing supports 56, 57 further comprises locking means to lock said securing slide in an inserted position of the latch in the opening arranged on one or the other of the connection panels 9.
  • these locking means comprise clips for locking the securing slides 51, 52 on their respective supports 56, 57.
  • the clips enable two different locking positions to be defined to be able to intercalate the connections of a differential unit when the securing support is in an intermediate position.
  • each securing slide 51, 52 and each securing support 56, 57 respectively comprise two pass-through holes 61, 62 which are arranged in such a way as to be facing one another when said securing slide is locked on its securing support.
  • These pass-through holes 61, 62 are arranged facing the terminal screw heads to enable said terminals to be tightened and loosened.
  • the securing system of the control unit 1 enables said control unit to be fitted on and removed from the circuit breaker 5, without damaging the insulating case of said circuit breaker.
  • the operating mechanism comprises a first transmission shaft 71 coupled with the rotary drive means 25 visible in figures 3 and 4 .
  • the first transmission shaft 71 performs transmission of a frontal command by means of a front operating handle the axis of rotation of which is perpendicular to the front panel 3 of the case of the circuit breaker 5.
  • the transmission shaft 71 is oriented along a first transmission axis that is substantially identical to the axis of rotation of the front operating handle which is coupled with the rotary drive means 25 and which enables frontal command of the circuit breaker 5.

  • the kinematic chain formed by the first transmission shaft 71, the first crank 81, the first crank pin 82 and the main slide 84 thereby enables the angular movement of the front operating handle coupled with the rotary drive means 25 to be transformed into an alternating movement of the hand lever 15 of the circuit breaker 5, and vice-versa.
  • the planes of movement of the front operating handle and of the main slide 84 are substantially parallel to the front panel 3 of the insulating case of the circuit breaker 5, whereas the first transmission shaft 71 extends perpendicularly to the slide wall 75 of the support 27 and is fitted between the two first flat parts 75, 76 of said support parallel to said planes of movement.
