Definitions

  • An electromagnet having the structure defined above is, for example, known from French Patent No. 1,603,300 where it is applied to a polarized relay effecting the switching of low currents.
  • the invention proposes to provide this known relay with improvements aimed at simplifying its structure when the core is associated directly or indirectly with a separate switch requiring, for its switching, the exercise of a higher force, while retaining the advantages which it can benefit from, relative to the generation of perfectly concentric call forces to the coil.
  • the aim is achieved thanks to the fact that two pairs of extensions, of the same first sign, placed symmetrically with respect to the axis of the coil form part of the same first piece of rectangular flow pipe surrounding a second piece of flow channeling which connects two other pairs of symmetrical extensions having signs opposite to the first and which surrounds a coil whose carcass is substantially crossed by the magnetic axes of permanent magnets disposed at the same axial level between branches of transverse flow channeling.
  • the pallet 11 rests on an external transverse branch 16 belonging to a first piece of flow pipe 17 in the form of a frame rectangular, while the pallet 8 rests on an internal transverse branch 18 of a second piece of frame-shaped flow pipe 19 which is surrounded in parallel by the first and which in turn surrounds the carcass of the coil.
  • another internal branch 20 is placed opposite the internal branch 18 of the frame 19 and that another internal branch 21 of this frame is placed opposite the external branches 20 respectively 16, so that each pallet is placed between two parallel branches.
  • These branches constitute pairs of transverse polar extensions 20a, 20b respectively 16a, 16b and 18a, 18b respectively 21a, 21b as will appear in FIG. 3.
  • Two permanent magnets 22 and 23 are placed symmetrically with respect to the axis XX 'between the arms 20 and 18 so that their magnetic poles of the same sign are applied against the same arm and their axis of magnetization NS, N'S', which are both parallel to the axis, substantially pass through the carcass of the coil. This results in a reduction in size and a difference in the length of iron which the flux of the magnet must travel to circulate towards the faces 18, 20 on the one hand and 16, 21 on the other hand.
  • the two internal branches therefore have the same magnetic polarity of a certain sign, while the two external branches in turn have the same magnetic polarity of sign opposite to the previous one.
  • the device which has just been described has two stable states, defined by the extreme positions of the core, for which, in the absence of excitation of the coil, the core can be traversed by two flows of opposite direction which are provided by the permanent magnets and which are transmitted alternately by the flow channeling parts.
  • the pallet 8 passes between the magnets and is applied to the branch 20, while the pallet 11 is applied to the branch 21.
  • an extension 30 of the core carries a third pallet 31 outside the frame 17 which is distant from the branch 20 for a rest position R where the core is moved to the left and which is pressed there for the opposite extreme working position T shown in this figure, while the pallet 8 n reach branch 18.
  • this electromagnet therefore has a monostable characteristic which can advantageously be used for controlling devices of the relay or contactor type.
  • a low parallel reluctance could also be provided by a third pallet 33, placed on an extension 34 of the core 5 ′ situated between the branches 16 ′, 21 ′ so as to place themselves in the plane of the branch 21 'through a slightly larger opening 35 of the latter while the pallet 11' is itself placed outside the branch 16 '.
  • This variant however causes the appearance of transverse forces of attraction on the pallet 33.
  • the magnetic circuit is closed by contacting the vanes 8 ', 33 against the branches 18' and 16 'respectively.
  • an assistance spring such as 36 to provide an axial force F capable of improving the monostable nature of the device.
  • This example particularly uses a synthetic molded part 70 playing the role of the coil carcass and providing association means capable of firmly applying the pole faces of the permanent magnets against the branches of the flux-conducting parts.
  • the carcass 40 of the coil 41 has a bore 42, the ends of which are adjusted to guide the core 43, and two transverse cheeks 44, 45.
  • One of these cheeks 45 may have a projection of low height 46 to ensure its centering in an opening 47 of the internal flow guide part 48, while the cheek 44 of generally rectangular shape has at each of its four vertices an elastic longitudinal column, two of which 49, 50 are visible in FIG. 6.
  • the permanent magnets 58, 59 which are placed between these parallel branches are kept in firm contact with them, thanks to a longitudinal force developed by the columns between the hooks and the outer surface 60 of the cheek 44; these same columns, which limit a centrifugal radial movement of the magnets, may include housing portions such as 61 to operate lateral guidance of the magnets, see also FIG. 8.
  • a complementary holding of the magnets intended to prevent their displacement towards the central axis, as well as to provide an angular guidance of the position of the pallets 67, 68, can be ensured by an annex guide piece 62, see FIG. 6, which comes be placed on one or other of the branches 57 or 53 and has columns or walls parallel to the axis such as those shown at 63 in FIG. 3.
  • these balusters which pass through openings 64, 64 'of the outer branch 57, see FIG. 7, are part of the same plate 65 pierced with an opening to allow the passage of an extension 66 of the core intended to transmit movements.
  • this extension is coupled to a contact carrier whose movements are angularly guided and if the branches 53, 57 carry, facing the polar surfaces, magnets, flat depressions preventing their movement towards the axis, we can dispense with '' use annex 62.
  • the means for connecting the ends 78 of the wire of the coil 3, see FIG. 9, can advantageously be attached to two of the columns such as 79 belonging to the molded part 70 ′, in the form of solder lugs, screw terminals, or rigid or flexible metal pads 80 suitable for operate an electrical connection by pressure and / or sliding;
  • Figure 9 shows the latter solution; if necessary, terminals can be placed at the ends of the hooks which do not come into contact with the external branch.
