Definitions

  • the present invention relates generally electrical devices with input and output terminals opening onto the same side of their housing, that is to say the electrical appliances comprising, on this face of their housing, on the one hand, holes, or cable entries, which provide access to input terminals, and, on the other hand, holes, or cable entries, which provide access to terminals exit.
  • the present invention relates more particularly, but not necessarily exclusively, the case where, as shown in this French patent No 77 38649, electrical appliances concerned are modular electrical devices, i.e. electrical appliances whose housing has, under a general parallelepiped shape, two main faces parallel, one rear side, two side faces and one side before.
  • These modular electrical devices have, overall, the same outline, and the width, or thickness, of their housing, that is to say the distance separating one from the other the two main faces of this case, is equal to a basic module common to all or is a multiple of this basic module.
  • the input terminals and the output terminals lead to the same face of the case, in this case a side face thereof, and that, in a traditional way, the phase bounds of this electrical appliance are established at the same level as that other electrical devices, its neutral terminals being themselves established at a level which, different from the previous one, is also the same as that at which the limits of neutral of these, there is the risk that inadvertently, and inadvertently, the phase power bar either jointly engaged by two separate teeth in the phase terminals of such an electrical protection device differential, and / or the same for the bar neutral supply, which would lead to a loopback on itself from this protective electrical device differential, and therefore, when it is taken out of service, or even to its deterioration, to the detriment of the security sought.
  • the present invention generally has for subject a provision to eliminate very simple such a risk.
  • this electrical device being generally characterized in that, the housing having, projecting, on its face concerned, between the holes giving access to the input terminals and those giving access to output terminals, a partition wall, the width of this partition wall, measured from the input terminals and outlet, perpendicular to the relevant face of the housing, is at least equal to the height of the bar teeth feed.
  • the partition wall thus provided according to the invention is systematically, and effectively, opposed to the simultaneous engagement of two teeth of the same bar supply to an input terminal and an output terminal.
  • the apparatus Electric 10 is a modular electric device.
  • Its housing 11 therefore has, in a general form parallelepiped, two main faces 20, which are parallel to each other, and, connecting these two to each other main faces 20 along its edge, a rear face 21, two side faces 12 and a front face 22, which are all perpendicular to the main faces 20.
  • the face rear 21 has, in its middle zone, a notch 23.
  • the two lateral faces 12 are substantially perpendicular to the rear face 21, and this is on one from which the 13P, 13N holes jointly open giving access to the input terminals 14P, 14N and those 15P, 15N giving access to the output terminals 16P, 16N.
  • the front face 22 finally, presents, in its part median, a projecting part 24, on which a controller 25 available to the user, and, each arranged respectively on either side of this projecting part 24, two lateral facets 26, which, established at the same level, are both substantially parallel to the rear face 21.
  • the width E, or thickness, of the housing 11, measured from to each other of its two main faces 20, is equal to double a basic module M common to all devices modular electrics, not shown, which can be associated the electrical appliance 10.
  • the holes 13P and 15P are established at the same level, being separated from each other a distance P equal to the basic module M.
  • holes 13N and 15N are established at the same level, distinct from the previous one, being also discarded one on the other by a distance P equal to the basic module M.
  • the holes 13N and 15N are each respectively offset from the holes 13P and 15P, parallel to the rear face 21 of the housing 11, of a distance P 'equal to half of the basic module M, and they extend between holes 13P and 15P and the rear face 21 of the housing 11.
  • the holes 13P, 13N, 15P, 15N have a generally rectangular outline, while that the holes 27P, 27N, 28P, 28N have an outline overall circular.
  • the housing 11 comprises a base 30, which forms one of its main faces 20, and a cover 31, which, in one piece with the front face 22, forms the other of these main faces 20, with, between this base 30 and this cover 31, substantially midway between the main faces 20, an insulating partition 32, which extends parallel to the faces main 20, from one to the other of the side faces 12, between the rear face 21 and the side facets 26 of the front panel 22.
  • a terminal block 33 which groups the output terminals 16P, 16N
  • a terminal block 34 which groups the input terminals 14P, 14N.
  • the input terminals 14P, 14N and the output terminals 16P, 16N are globally aligned with each other.
  • the housing 11 has, in projection on its face 12 concerned by the holes 13P, 13N, 15P, 15N, in this case one of its lateral faces 12, a wall of separation 35.
  • this wall separation 35 is substantially perpendicular to the face 12 concerned of the housing 11 and it extends parallel to the faces main 20 of it.
  • the wall of separation 35 actually only spans a fraction of the height of the relevant face 12 of the housing 11.
  • the wall of partition 35 has a generally rectangular outline.
  • its free angle zones 36 i.e. those of its zones of angle which are at a distance from the face 12 concerned of the case 11, are softened, for example by a rounding 37.
  • the partition wall 35 is in the general form of a thin wafer, whose thickness E ', measured perpendicular to the main faces 20 of the housing 11, is relatively weak, being however sufficient for its good mechanical strength.
  • a bar supply 38 having, from place to place, following a step P regular, teeth 39 by which it is able to be engaged in any input terminal 14P, 14N or exit 16P, 16N.
  • this sill 41 is provided with a coating 42 of material insulating.
  • the width L'1 of the wall of separation 35 measured from input terminals 14P, 14N and output 16P, 16N, perpendicular to face 12 concerned of the housing 11, that is to say on the side face 12 of this housing 11 on which it projects, is at least equal to the height L of the teeth 39 of this feed bar 38 measured from sill 41.
  • the height L of the teeth 39 must in all cases be assessed in projection on a plane which, passing through the sill 41, is parallel to the right end of these teeth 39.
  • the width L'2 of the partition wall 35 is at least equal to the height L of the teeth 39 of the feed bar 38, such as represented.
  • the wall of separation 35 is in one piece with the housing 11.
  • the partition wall 35 opposes systematically to a simultaneous engagement of two teeth 39 of the same power bar 38 in the input terminal 14P and in the output terminal 16P, or in the input terminal 14N and in the output terminal 16N, whether teeth 39 straight or it is bent 39 teeth.
