Definitions

  • the present invention relates to a circuit breaker whose housing contains a tripping and resetting mechanism capable of acting on separable contacts to open and close at least one electric current path.
  • a circuit breaker whose housing contains a tripping and resetting mechanism capable of acting on separable contacts to open and close at least one electric current path.
  • passage openings for an "on" control button and a "stop” control button accessible to an operator.
  • the control buttons are push buttons mounted in the housing so as to be able to slide alternately between two operating positions and having a front support face for the operator's finger.
  • the operator wishes to close the contacts, he presses the on push-button which remains pressed, while the stop push-button is automatically put in the extended position relative to the housing.
  • the operator presses the stop push button; it remains pressed, while the on push-button is automatically returned to the extended position.
  • the alternating position of the pushbuttons thus gives the operator a clear idea of the state of the circuit breaker.
  • the main object of the invention is to reconcile, in a circuit breaker of the type mentioned in the introduction, an ergonomic manual control separating the on and off control functions in combination with a good visualization of the running operating state and, preferably, on and off operating states of the circuit breaker.
  • the control buttons preferably placed side by side to pivot around a common axis substantially located at one side of the housing perpendicular to its front side, thus provide not only a differentiated projection, but also a difference in front height of their second end and therefore a satisfactory visual indication of state.
  • This indication is preferably corroborated by the presence of indications carried by the housing near the first end of the support face, preferably by the pins of the buttons, to be alternately released and masked by the latter, and / or opposite transparent windows made in the bearing faces.
  • Figure 1 shows in perspective a circuit breaker according to the invention.
  • Figures 2 and 3 show in elevation a front part of the circuit breaker housing illustrating the pivoting on button in the extended and respectively retracted position.
  • Figure 4 is a perspective from below of the power button.
  • Figure 5 is a partial front view of the front part of the housing, the buttons having been removed.
  • Figures 6 and 7 show laterally and in bottom view the stop button of the circuit breaker.
  • Figures 8 and 9 show in partial elevation the front face of the housing for the respective stop and on states of the circuit breaker.
  • Figures 10 and 11 show in side elevation a variant of the on button in two distinct operating states.
  • the electrical device illustrated in the figures is a circuit breaker known as a motor circuit breaker, comprising a housing 10 which contains a triggering mechanism with lock and reset, capable of acting on movable contacts separable from fixed contacts, for opening and closing several current paths established between pairs of respective terminals 11, 12.
  • a circuit breaker known as a motor circuit breaker, comprising a housing 10 which contains a triggering mechanism with lock and reset, capable of acting on movable contacts separable from fixed contacts, for opening and closing several current paths established between pairs of respective terminals 11, 12.
  • the motor circuit breaker comprises, to act manually on the mechanism, two buttons 13, 14 mounted side by side pivoting about a common axis X and passing through two respective windows 15, 16 which are formed in the front wall 17 of a nose 18 of the housing 10.
  • the buttons may not be mounted side by side.
  • the buttons take alternately and mutually reverse, a retracted operating position and an extended operating position relative to the wall 17.
  • the buttons 13 and 14 cooperate with the mechanism by means of a control part 19 (see figures 2 and 3) with which they are engaged and which pivots about an axis Y perpendicular to the plane containing the axis X.
  • the pivoting "on” button 14 will now be described with reference to FIGS. 2 to 4. It comprises a bearing face 20 for the operator's finger. This bearing face is flat, but can also be slightly concave or convex, and it has two ends 20a, 20b; it is unique, that is to say that the operator actuates the button only by pressing on this support face and in one direction only.
  • the first end 20a of the bearing face 20 has a displacement of small amplitude determined by the proximity of the axis X of a pin 21 on which the button pivots.
  • the end 20a of the bearing face has a bevel 22 whose role will appear later.
  • the button 14 has two curved pivot arms 23 capable of sliding , on the one hand, by a face 23a on the pin 21, on the other hand, by an opposite face 23b on a fixed support element 24.
  • the support element is extended towards the front face 17 of the housing by a display means 25 capable of appearing opposite a window 26 of the button when the latter is in its retracted operating position.
  • the window 26 consists of a patch of transparent material.
  • the button has a control arm 27 cooperating with the control part 19 of the mechanism.
  • the arm is provided with a housing 28 whose shape allows it to engage on a pin 29 of the part 19 and to cooperate with it to actuate, or respectively be actuated by, the part 19.
  • a notch 30 expected near the free end of the control arm 27 allows the button 14 to be elastically entered into the opening 16, but avoids its untimely exit by stopping against an edge of the window 16 or against another stop provided in the housing.
  • the control arm 27 comprises an orifice 31 for passage of a padlock in order to maintain, thanks to this, the button in the extended position.
  • the surface of the journal 21 has, at its end situated towards the front surface 17 of the housing, a display area 32.
  • This area 32 carries, for example, the indication ON for the button 14 and the indication OFF for the button 13 (see figures 1, 5 and 8, 9).
  • the range is alternately cleared and concealed by the end 20a with small clearance of the support face 20. In each pair of operating positions of the two buttons, the display ranges of these are one clear, the other obscured.
  • the end 20a of the bearing face masks the area 32, the bevel 22 being in alignment with the adjacent part of the horizontal face 18a of the nose 18 which is perpendicular to the anterior vertical face 17; it can be seen in FIG. 3 that the end 20a, helped by the shape of the bevel 22, clears the area 32.
  • the button Near its edges and opposite the bearing face 20, the button comprises abutment surfaces 33, 34 which are applied, to limit the retraction stroke of the button, against a lower edge 35 or side edges 36 of the opening 16 of the face 17.
  • buttons 13 will be assigned a notation 'when this is necessary to distinguish an element of button 13 from an element homologous to button 14.
  • each pin 21 can be broken down into two bearings 37, 38 each cooperating with one of the pivot arms 23; and that each display means 25, 25 ', for example "0" for the stop button 13 and "1" for the start button 14, is carried by a horizontal arm 39, 39' of the support element which determines a sliding surface for at least one of the arms 23.
  • the opening 16 provided for the start button 14 is a little higher than the opening 15 associated with the stop button 13, because the corresponding control arm 27, which includes the orifice 31, is higher.
  • Intermediate horizontal edges 42 are added to the lower edges 41 of the openings to guide respective cylindrical surfaces 43, 44 of the buttons.
  • the pivoting "stop" button 13 is illustrated in FIGS. 6 and 7. It will not be described further since it is similar to button 14, except for the control arm 27 which is reduced since it does not need to include the orifice 31. Streaks 45 or other anti-slip provisions can be provided on the lower part of the support face 20 of the two buttons.
  • the swivel buttons are mounted in the housing as follows.
  • the free end of the pivot arms 23 is introduced between the pin 21 and the support element 24, then the notch 30 exceeds the hard point associated with it and the control arm 27 engages by its housing 28 on the pin 29 of the control part 19.
  • To open the contacts the operator presses the stop button 13 to put it in the extended position; only the 32 'OFF range and the means 25 "0" of button 13 are then visible (Figure 8). As can be seen in FIGS.
  • the end 20b of the on button 14 is situated in the on state and in the off state of the circuit breaker at a level differentiated from the end 20b ′ of the stop button 13 , this being reflected both by a differentiated projection from the face 17 and by a difference in height h of the front projections of the lower edges of the buttons, whether the stop button is actuated in maintained mode or by pulses.
  • the passage opening 31 for the padlock is provided in a pull tab 50, more precisely in a wide part 51 of this pull pull, which is housed in the start button 14 so as to assume a position cleared ( Figure 10) and an output lockout position (Figure 11).
  • the wide part 51 of the pull tab is located in the vicinity of the end 20b with large clearance of the button.
  • the pull tab further comprises a tail 52 with an opening 53 whose upper edge cooperates with a stop 54 of the housing to stop the pull tab in the extended position.
  • the zipper cooperates with its housing 55 in the button 14 by means of suitable guide and abutment surfaces; it remains held in the retracted position by snap-in or retaining elements and is applied in the extended position against the front face 17 of the housing.
  • the invention is applicable to any circuit breaker or contactor-circuit breaker in which it is desired to reconcile the safety of manual actuation and the quality of the status display.
