Definitions

  • Electrical switch protection device for an electrical circuit comprising a housing, a tilting drawer articulated with respect to the housing so as to be able to manually switch from a closed position to an open position and vice versa, a switch having, on the one hand, a contact fixed and on the other hand, a movable contact mechanically associated with the drawer so as to be open when the latter is open, and means for automatic cutting of the electrical circuit comprised between two terminals of the housing, these means intervening during the passage of an excessive current in the circuit, the movable contact being separable from the fixed contact under the effect of a spring device and magnetizable part cooperating with a coil placed in the circuit, the device being reset during an opening movement and manual closing of the drawer.
  • Such devices are used for the protection of lines and, when they are arranged in narrow modular boxes, then often equip domestic distribution boxes.
  • US-A-3,030,470 relates to a protective device which comprises a fixed housing, provided with a fixed contact and a manually operable tilting cover, articulated on the fixed housing and provided with a movable contact, the housing and cover comprising magnetothermal means for opening the movable contact.
  • This protective device does not, however, allow the user to ensure with ease and certainty that the contacts have been separated during a magnetic or thermal trip or during manual opening of the drawer.
  • the object of the invention is therefore to provide a protective device free from the aforementioned drawbacks and which also has sectioning properties and a structure eliminating the risk of accidental contact of personnel with a live element. .
  • an electrical switch device for protecting an electrical circuit
  • a switch having, on the one hand, a fixed contact and, on the other hand, a movable contact mechanically associated with the drawer so as to be open when the latter is open, and means for automatic circuit breaking electric between two terminals of the box, these means intervening during the passage of an excessive current in the circuit, the movable contact being separable from the fixed contact under the effect of a spring device and magnetizable part cooperating with a coil placed in the circuit, the device being reset during a manual opening and closing movement of the drawer, and being carried by the drawer, so as to be separated from the fixed contact by a dry distance sufficient operation visible from the outside when the drawer is opened manually.
  • this device is more particularly characterized in that the movable contact is electrically disconnected from each of the terminals and can be observed directly when the drawer is open.
  • the disconnection is obtained by virtue of a movable bridge contact which cooperates with two fixed contacts connected respectively to a terminal and to the coil.
  • connection and disconnection are obtained thanks to a removable coupling which takes place elastically during the opening and closing of the drawer between on the one hand, a pin, around which pivots a lever carrying a movable contact to simple cut, and on the other hand, at least one conductor electrically connected to a terminal.
  • the pivot axes of the tilting drawer and the movable contact carrier lever are distinct.
  • the pivoting axis of the tilting drawer can be located at a distance from the rear face of the housing allowing the housing of the coil device and magnetizable piece between the axis and the rear face, the fixed contact and the movable contact being located in front of the device.
  • a first device 1a according to the invention which is shown diagrammatically in FIG. 1a, comprises a housing 2 having a front face 44 and a rear face 43 provided for example with fixing means cooperating with standardized profiles.
  • an electrical circuit 10 comprising in series: a switch 5 having a movable contact 7 and two fixed contacts 6a, 6b, thus that an automatic opening device 9 comprising a coil 11, a magnetizable core or pallet 12 with which is associated an insulating screen 13 capable of being propelled by this core between the contacts 7 and 6; an elastic device 14, of abrupt opening of the movable contact 7 of the switch 5, is triggered by the movement of the core or of the screen when a significant overcurrent flows in the circuit, and in such a way that the contacts of the 'switch 5 are barely open when the screen moves between them.
  • a drawer 8, movable on the front face 44, has coupling means 24 which allow it to open the switch 5 voluntarily by acting on the movable contact 7; this same drawer allows when it is opened to make visible the position of this movable contact so that the user can on the one hand ensure that the line is electrically isolated and can on the other hand reset the device 14 when the latter has been triggered automatically.
  • FIG 3 which shows a particular embodiment of the invention according to Figure 1a, where a single-pole switch is disposed in a modular housing 2 of small modular width "e", for example equal to 8.5 mm
  • the terminals 3 and 4 are placed in a median plane PP 'parallel to two lateral faces 51, 52 belonging respectively to two half-housings 2a, 2b assembled for example along a joint plane contained in the plane PP' .
  • the components of the circuit 10, which are visible in Figure 2, include a folded conductor 37, connected at one end to terminal 3, and carrying at its other end, a fixed contact pad 6a.
  • An intermediate part of the conductor is held in a groove 39 of an insulating block 35, better visible in FIG. 5, which has another opposite groove 38, capable of receiving one end of a folded conductor 36 on which is placed a second fixed contact pad 6b; an insulating partition 29 of this block separates the two fixed contacts.
  • the conductor 36 is also connected to one end 11 a of winding the coil 11, the latter cooperating with a magnetizable yoke 9a and with a magnetizable plunger core 12 to which a spring 12a gives a rest position " I " visible on the Figure 2; the other end 11b of the coil 11 is also connected to terminal 4.
  • a fork-shaped contact bridge 28 carries two movable contact pads 7a, 7b placed at the ends of the branches 28a, 28b, and is held with an angular play by an insulating contact carrier 17 able to pivot about an axis ZZ 'perpendicular to the plane of the figure.
  • the contact carrier has for this purpose a pin 24a which is engaged in two bearings 24b placed in parallel cheeks of a tilting drawer 8, such as those shown in 8a, 8b in FIG. 6 and in FIG. 4.
  • the contact carrier 17 also has a heel 15a placed in the vicinity of the contact pads 7a, 7b and a spout 16 which is opposite to it.
  • the spout 16 rests on an abutment surface 19 of a part 20 capable of pivoting about an axis YY 'parallel to ZZ.
  • This part which also has an inclined ramp or cam surface 22 leading to the abutment surface 19, also has a surface 32a capable of cooperating for a certain angular position with a support 32 of the housing 2, and a radial arm 20a receiving the clockwise thrust of a compression spring 21; the thrust of this spring is balanced by the action of the spout against the surface 19.
  • the contact carrier 17, the spring 18, the part 20 and the spring 21 are carried by the slide 8 which rocks around the axis YY 'placed concentrically with a stud 41 on which a bore pivots. 42 of this part 20, see also FIG. 6; the drawer 8 is itself pivoted in half-housings using surfaces or means not visible in the figures.
  • This screen which is guided with a slight play by this groove in one direction, also receives a complementary guide thanks to the surface 35a of the insulating block 35 see FIG. 5 and to a groove 35b of the partition 29; these guides orient the screen so that a movement of direction F in its plane causes the ends of the branches 30a and 30b to penetrate with zero or extremely reduced play in two notches placed opposite.
  • the plunger core 12 which is instantly attracted to the center of the coil 11 , communicates a very rapid movement on the screen 13.
  • the boss or bosses 15 raise the heel 15a of the contact carrier 17 by communicating to the latter an angular movement which releases the spout 16 of the stop 19.
  • the contact bridge 28 is associated with a clearance limited to the contact carrier 17 by means of oscillating means 17b and a finger 15b. These means make it possible, depending on the value of this clearance, to first separate the contact bridge from the fixed contacts very quickly, and then to have this opening confirmed by the snap-action device 14, which notably comprises the part 20 and the spring 21 .
  • the edges 30a, 30b of the screen can engage in these grooves and reach an extreme working position T before returning elastically to the starting position 1 (see FIG. 2).
  • the groove bottoms 31 a and 31 b are connected to channels or vents which connect them to the atmosphere and thus allow the gases released during the shearing of the arc not to slow the movement and not to subject the housing to undue stress.
  • the lateral edges 13c, 13b of the screen move by operating, at least temporarily, total isolation between the two spaces placed on either side. other of the screen.
  • the space containing the movable contact can also be connected to the atmosphere by a dimensioned vent to prevent an overpressure from opening the drawer.
  • the closing of the switch 5 is carried out first by a movement of alpha direction, which is given to the drawer to reset the part 20, and then by a folding of the drawer in its housing.
  • the part 20, which is supported on the housing thanks to the cooperation of the surfaces 32a, 32 remains fixed, while the contact carrier 17 is driven.
  • the relative movement between the ramp 22 and the spout 16 brings the latter from the top 22a of the ramp against which it was located towards the stop 19 against which a locking then takes place thanks to the action of the spring 18; during this same movement the spring 21 which is housed in a cell 26 of the drawer is compressed between the latter and the arm 20a.
  • a second device 1b which is shown in Figure 1b, comprises a housing 2 'having a front face 44' and a rear face 43 'provided for example with fastening means cooperating with standardized profiles.
  • an electrical circuit 10 ′ comprising in series: a switch 5 ′ having a movable contact 7 ′ and a fixed contact 6 ', and a removable electrical coupling device 81 capable of connecting the movable contact to an automatic opening device 9' comprising a coil 11 'cooperating with a magnetizable core or pallet (12') capable of striking the contact mobile 7 'to cause the instantaneous opening of the switch when a large overcurrent flows in the circuit;
  • a deformable elastic mechanism 14 ' triggered by the core 12 ', serves to confirm the opening of the movable contact by keeping it in a position remote from the fixed contact.
  • a drawer 8 ′ movable on the front face 44 ′, has coupling means 24 ′ which allow it to voluntarily cause the opening of the switch 5 ′ by acting on the movable contact 7 ′; this same drawer makes it possible, when it is opened, to make the position of this movable contact visible to ensure that the line is electrically isolated and to reset the device 14 'when the latter has been triggered automatically.
  • the circuit 10 flows from terminal 3' to terminal 4 'passing through the coil 11' which is then connected to a conductor 37 'carrying the fixed contact 6', then by the simple movable contact 7 'which is placed at the end of a contact lever 28 'pivoting around a pin 24'a, and by two parallel return conductors such as 60 and 60' which receive the pin 24a and which lead to terminal 4 ', see also Figure 8.
  • Each of the conductors 60, 60 ' has for this purpose the shape of an L in the interior corner of which is placed an open notch 63 adapted to receive one of the ends of the pin 24'a and whose short branch 61 has a inclined surface 62, see in particular FIG. 10.
  • the switch device 1b When the switch device 1b is in the state of FIGS. 7 and 8 where the drawer 8 'which pivots about an axis 64, is closed, the ends of the pin 24' a are each placed and, with play, in V-shaped grooves 24'b belonging to the drawer.
  • the axis of this pin is distinct from the axis 64 of pivoting of the drawer 8 '.
  • a tension spring 21 ' having a fixed end 67, engaged in a support 66 of the drawer and a movable end 68 which is connected to a link 69; the latter has a hooking point 70 which is opposite the end 68 and which connects it to a point 71 of the contact lever 28 'remote from the pin 24'a.
  • an arc extinguishing chamber 76 which is placed opposite the cut-off zone of the switch 5 ', communicates with the outside by means of vents such as 77.
  • the members 21 ′, 28 ′, 69, 70, 24 ′ b, 79 and 80 constitute the elements of the deformable and resettable elastic mechanism mentioned by 14 ′ in FIG. 1 b.
  • the drawer When to reset the mechanism 14 ′, the drawer is opened by hand in the alpha direction, the grooves 24 ′ b come into contact with the ends of the pin 24 ′ a and drive it with it, causing it to disengage from the notches 63 , which isolates the lever 28 'from terminal 4', see the drawer in dashed lines in position A in Figure 10.
  • the contact lever 28 ' which has just been described is therefore electrically connected to terminal 4' and mechanically connected to the conductors 60, 60 ′ in the closed position of the drawer by a removable coupling, referenced by 81 in FIG. 1 b, which releases it for the open position of the drawer.
  • a further rotation of the slide 8 ' which brings it to position B shown in dotted lines in FIG. 10, first brings the end 72 of the contact lever 28' against a stop surface 78, belonging for example to box 2 ', which immobilizes this lever; continuing the movement of the drawer to position B then causes the hooking point 67 of the spring 21 'to pass to the right of a line passing through the pin 24'a and the point 71, so that the link 69 now transmits to the lever 28 'a couple of anti-clockwise direction which communicates to it a rotation in the same direction as the latter, until a meeting takes place between it and a stop 80 placed in the drawer 8', see figure 7.
  • the switching device performs the function of a disconnector in which the electrical connection part, that is to say the movable contact 7 'is separated from the fixed contact 6 'by a significant distance "d"; moreover, the mobile contact is made visible, which constitutes a guarantee for the user that this cutting operation has been carried out; moreover, the lever 28 'being separated from the other conductive parts 60, 60' accidental contact with this lever does not present any danger.
  • the ends of the pin 24'a are facing the inclined surfaces 62, and slide thereon until they are opposite the notches 63, into which they penetrate then; the ends of the pin 24'a are again separated from the grooves 24'b when the drawer reaches its closed position.
  • the stability of the support of the pin 24'a, either in the notches 63 or in the grooves 24'b, is due to the fact that the latter are open in a direction opposite to the point of attachment 67 of the spring 21 '.
  • the angular strokes made by the drawers and by the movable contacts of these devices are chosen so that the sectioning distances “d imposed by standards for the categories of jobs provided for, are respected.
