Definitions

  • the invention relates to an electromagnetic control reversing device comprising, on the one hand, two identical contactor systems each equipped with an electromagnet having a fixed yoke, a coil and a movable armature associated with a set of switches including the fixed contacts are connected to terminals and, on the other hand, a mechanical locking device using two levers, the first ends of which are coupled to the armatures while the second ends move alternately in a common region which can only be occupied by one of these second ends.
  • Such devices are frequently used in installations where the direction of a motor is changed by reversing the order of the phases, and where it is desired to improve by other means the reversal safety offered by an electrical locking circuit.
  • Known devices for example that described in document DE-A-3011779, are generally obtained by the electrical association of two three-pole contactors between which, or next to which there is a mechanical locking sub-assembly containing the two levers mentioned. above.
  • Such an embodiment can only give complete satisfaction if the manufacturing tolerances of the contactors and of the locking sub-assembly are kept within relatively narrow limits so that the sum of these tolerances does not exceed those which guarantee proper operation of together.
  • the invention therefore proposes to provide a switch-reversing device having the general constitution mentioned above but in which measures will be taken so that the user does not have to carry out an assembly requiring respect for precise respective positions and so that assembly in the factory as well as verification of proper operation can be greatly facilitated.
  • FIG. 1 where the reference 3 relates to a half-casing having mainly side walls 4, 5 and two longitudinal walls 6, 7. These side walls as well as a central partition 8 extend to a plane P which limits them and are perpendicular thereto, the longitudinal wall 7 is substantially parallel thereto; the longitudinal wall 6 is perpendicular both to the side walls 4, 5 and to the plane P. Between the walls 4, 5 and the central partition 8 are formed two identical housings 9, 10 (see also fig.
  • each electromagnet also comprises, in a known manner, a fixed yoke 23, 24, a coil 26, 42 and a return spring 27, 28.
  • each upper volume are placed fixed contacts such as 29, 30 respectively 31, 32 (see fig. 2) which are separated by internal insulating partitions, such as 33, respectively 34.
  • the fixed contacts are connected to aligned output terminals 35, placed outside the half-box and therefore outside the two housings, in an upper region 36 of the half-box. These output terminals are separated by isolation ribs 37 (see fig. 5 and 6) and include power terminals 38, 38 'and relay 110,110' and coil terminals 39, 39 '.
  • the coil terminals lead to internal contact parts 40, respectively 41 which are in elastic contact with one of the ends of the winding of each coil 26 respectively 42 (see fig. 2).
  • Each frame 21, 22 is linked to the corresponding contact carrier by a rib 43, 44 transverse to the plane P, and their movements are guided in the plane P by the cooperation of the contact carriers with the internal partitions 33 respectively 34.
  • Each contact carrier 19, 20 carries movable bridge contacts such as 45 respectively 46, and such as 47 respectively 48.
  • the three contact bridges such as 45 and 46 cooperate with corresponding fixed contacts 29, 30 of the half-housing to form closing switches T, while the contact bridges such as 47 and 48 cooperate with corresponding fixed contacts 31, 32 to constitute opening switches R.
  • Each contact carrier 19, 20 therefore actuates a particular set of switches 49, 50 respectively.
  • Each rib 43, 44 of the contact carriers 19, respectively 20 carries a transverse finger 51, respectively 52, which moves at the same time as the corresponding armature parallel to an axis ZZ '(see fig. 5 and 3).
  • the longitudinal wall 7 has a longitudinal cavity 53 located between the first region 36 receiving the terminals and the fixed contacts and the second region 14 adjacent to the sole 13 (see fig. 2 and 1).
  • This cavity has two studs 54,55 perpendicular to the plane PP 'on which are pivoted two reciprocal mechanical locking levers 56,57.
  • levers have, in known manner, at ends 63, 64, two edges 58, respectively 59, placed in the vicinity of one another in the same region 60 and two curved bearing surfaces 61, respectively 62, while that other opposite ends 65, 66 each have an oblong opening 67, respectively 68 which is able to cooperate with one of the rib fingers 51, respectively 52 (see also fig. 5).
  • a corresponding locking lever places its bearing surface opposite the edge of the other locking lever, which prevents parallel movement of the other, a notch 69 of the central partition 8 placed opposite of the cavity 53 authorizing the cooperation of the two levers (see fig. 5 and 1).
  • covers 70 which have an identical shape. to that which would be obtained by cutting the half-housing 3 by a median plane QQ 'passing through the central partition 8; however, it is not intended to have cavities on the covers which would be useless for their function of closing the housings.
  • Each of these covers completes the guiding of a frame and a contact carrier and has fixed contacts such as 72 which cooperate with the contact bridges and aligned input terminals 73 connected to these fixed contacts (see fig. 5, 1 and 6).
  • the input terminals 73 are divided, on the one hand, into terminals 72 ', 73 "for each cover and, on the other hand, into power and relay terminals 74, 75, respectively 76, 77 and into terminals of coil 78, 79 in a similar manner to those of the half-housing and are therefore placed in upper regions 80, respectively 81, covers 70, respectively 71, divided by insulating partitions 82, 83 (see fig. 6).
  • the half-housing 3 is equipped with the fixed contacts, the coil parts, the output terminals, the two levers and the contact carriers fitted, then the covers themselves equipped with fixed contacts and terminals. input are associated with the half-housing.
  • the fixed elements 92, 93 of each electromagnet are introduced into the respective housings 9, 10 by two openings 94, 95 which remain in the bottom 96 of the housing 2 between the parts 2 and 70, 71 (see fig. 4 and 2).
  • the locking levers 56, 57 move in a plane RR ', parallel to PP' and passing through the cavity 53; this RR plane 'passes substantially through cells 105 in which are housed, side by side and in the same order, the output terminals 35 of the same kind of the two sets of switches 49, 50 associated respectively with each electromagnet, thus as the coil terminals 78 and 79.
  • the wall 106 of the cavity 53 preferably carrying the pins horizontally and downward; this orientation can be made necessary by a corresponding orientation of the wiring marks 107 carried by the longitudinal wall 6 which will become a front face when the bottom of the sole 13 is fixed to a vertical wall 108.
  • the parts 3,70,71,97,98 can advantageously be obtained each in a single piece by molding of thermoplastic material, which will in particular allow to give to the guide surfaces which ensure the sliding of the contact carriers, and to the pivots 54 , 55 locking levers for defect-free positions.
  • the finished device has an excellent rigidity provided in particular by the numerous elastic hooks which is further improved when the bases are associated with a fixing profile 109.
