Definitions

  • the invention relates to an electrical reversing contactor device comprising two systems of electromagnets and two systems of power switches housed in a common housing, also receiving a mechanical locking device capable of preventing simultaneous movement of the moving parts of armature of these two systems, reciprocal locking switches being also arranged in the supply circuits of these electromagnets, to prevent the excitation of that of these two electromagnets which is not concerned.
  • this locking is carried out using auxiliary switches, the contacts of which are placed in series with the coils, these switches being either associated externally with the common housing, or else respectively associated with each of two neighboring contactors when, in the absence of a combined device, two separate contactor devices must be associated with which is a mechanical locking device.
  • the invention therefore proposes to provide a contactor-reversing device whose general constitution responds to that mentioned above, and in which will be carried out a complete integration of electrical and mechanical locking means in order to simplify the task of the fitters and that of the cable operators or that of the personnel maintenance, while improving the overall reliability of this device, and not depriving the user of a pair of switches on auxiliary contact boxes which he might feel the need by associating them with each of the contactors.
  • the locking device uses in a known manner a movable mechanical locking part placed in the housing which can be moved by each of the moving parts of the two electromagnets being placed on either side thereof. , and which also cooperates with two electrical locking switches with opening housed in this housing and actuated by this moving part, one of the terminals of these switches being connected internally by a particular conductor to an input of the coil which it controls .
  • a reversing contactor device visible in FIGS. 1 and 2, comprises a molded case 2 having on either side of a central housing 3 crossed by a median plane RR ′ of the case, two cavities 4, 5 able to receive each a system of power switches with own electromagnetic control 6, respectively 7.
  • Each system comprises an electromagnet such as 8 having a fixed yoke 9, an excitation coil 11, and a movable armature 12 which is coupled to a contact carrier 13 intended to receive movable contacts of power switches 14. Return springs not shown give these frames rest positions remote from the respective cylinder heads.
  • the terminals of the power switches 15, 16, 17; 18, 19, 21 and 22, 23, 24; 25, 26, 27 are arranged in two regions 28, 29 of the front face 31 of the device between which the central housing 3 opens in an intermediate region 20.
  • Each particular contact carrier such as 13a, 13b, see FIG. 1, has a central groove 32a, respectively 32b directed towards the housing 3, the latter being substantially limited by two parallel walls 33, 34 and a complementary wall 35 extending by a central partition 36 placed in the median plane RR ′ parallel to the walls 33, 34.
  • This partition 36 has a notch 37 open towards the front face 31 of the device and visible in FIG. 4, having two opposite parallel edges 38, 39 and a bottom 41 whose center is occupied by a projection 42 being in a medium plane PP ′ common to the moving parts of the two electromagnets and perpendicular to the plane RR ′.
  • This projection 42 is limited by concave and symmetrical curved surfaces 43, 44 which extend on either side of the latter in the plane of the partition 36.
  • the notch is occupied by a movable locking part 30 having in the plane RR ′ where the partition 36 is located a cam surface 40 in the shape of a heart which is limited by two curved surfaces convex 45, 46 intersecting to form an acute vertex 47; moreover, this movable part comprises two lateral protruding circular cheeks 48, 49 which are placed parallel on either side of the plane of the cam and which come to adjust on opposite faces 51, 52 of the partition 36 leading to the 'notch, see Figures 1, 2 and 5, in order to be able to execute oscillatory movements in its plane.
  • this moving part can take are guided, on the one hand, by virtue of the presence on it of these cheeks and, on the other hand, by virtue of the contact with lateral guide surfaces 53, 54 of the cam against the edges 38 , 39 of the opening; these movements are for example communicated to the movable locking part 30 thanks to the presence of two transverse pins 55a, 55b which are projecting in opposite directions and symmetrically with respect to a line ⁇ common to the planes of symmetry RR ′ and PP ′, In order to penetrate respectively into the grooves 32a, respectively 32b, to couple with the corresponding contact carriers 13a, respectively 13b.
  • These pins have parallel axes which each pass substantially through the center of curvature of the convex surfaces 45, respectively 46 from which they are the most distant.
  • this movable locking piece carries two bosses 56a, 56b which are arranged symmetrically with respect to this line ⁇ and which, for certain angular positions, come to apply or not, see FIG. 4, mobile contact pads 57a, 57b against fixed contacts 58a, 58b by means of elastic deformations which they communicate with two flexible blades 59a, 59b at the ends of which these pads are arranged, see FIGS. 6 and 7.
  • These bosses are arranged in planes parallel to the lateral cheeks and externally to those -this. These blades circulate substantially parallel to the plane RR ′, and between them.
  • Each of the switches 60a, 60b each formed by a fixed contact and by a movable contact 57a, 58a, respectively 57b, 58b, is in the closed state when the movable locking piece is in a rest position which is illustrated in Figure 4, and which results from the existence of simultaneous rest states of the two electromagnet systems.
  • This movable locking piece, as well as the two electrical locking switches associated therewith, are placed in the central housing 3 where the partition 36 establishes galvanic isolation and transverse guidance; this housing therefore has, see Figure 2, at least in its region close to the front face, two cells 61a, 61b each receiving a switch as well as input and output terminals 62a, 62b, respectively 63a, 63b.
  • FIGS. 2 and 3 As can be seen physically in FIGS. 2 and 3, and diagrammatically in FIGS.
  • terminals 8 and 9 these terminals belong in pairs 62a, 63a; 62b, 63b to electrical locking circuits, circulating parallel to the electrical circuits traversed by the currents of the power switches going for example from the input terminals 15, 16, 17 to the output terminals 18, 19, 21, and are located on either side of the average plane PP ′.
  • Terminals 71, 72 and, respectively, 73, 74 accessible from the outside represent the connection terminals of the excitation coils associated with the two electromagnets 6, respectively 7.
  • terminals of these locking switches, excitation coils, and these power switches are for example electrically connected by circuits visible in FIGS. 8 and 9.
  • the locking part switches in direction G taking into account the retention action operated by the groove of the armature which is not excited (see Figure 6) , or direction D (see Figure 7), by prohibiting any subsequent movement of the armature belonging to that of these electromagnets which is not excited; this prohibition, which naturally extends to the electrical consequences resulting for example from a shock, is operated thanks to the existence of established mechanical interactions, on the one hand, between the surfaces 43 and 45, respectively 44, 46 and, on the other hand, between surfaces 53 and 38 or respectively 54 and 39, see Figures 6 and 7.
  • the mounting of the electro-mechanical locking system 30; 60a, 60b in its housing 3 is extremely easy due to the proximity of its opening to the front face 31; notches or passages such as 81, 82, see FIG. 11, formed in crosspieces such as 85, 86 and coming from molding with the common housing 21 in half-housings 87, 88 created by the partition 36 make it possible to operate a easy installation in the factory and efficient attachment of serrated extensions such as 83, 84 belonging to the parts of the terminals 62, 63, see FIG. 12. These cross-members also contribute to the stiffening of the partition 36.
  • a front cover 74 visible in FIGS. 1 and 3, makes it possible to close the opening 75 of the housing where it opens onto the front face 31 of the device, and establishes galvanic isolation both thanks to its lateral friction on opposite walls of the device, such as 75, only thanks to the presence of a central rib 74 ′ extending the partition 36.
  • the cavity receiving the locking piece and the switches opens onto a front face 31 of the device.
  • This arrangement provides mounting convenience when the housing 2 or its base, if it has one, have two housings 91, 92 which open in the same direction to each receive an electromagnet system. Each of these housings is closed during the fixing of the cover 93, respectively 94, receiving the power switches 14, their terminals 15 ... 27 and, where appropriate, the corresponding electromagnet armature 13a, respectively 13b .
  • this arrangement makes it possible to easily install flexible connecting conductors or other conductive parts 180, 181, respectively 182, 183 going from the coil 11 to the associated switch 60a, respectively 60b, see FIGS. 10 and 13, and makes it possible to carry out a final control of the electro-mechanical locking device in a convenient manner before the fitting of the cover 74.
  • the coil thus usually exhibits two connection terminals such as 175 , 176; 177, 178.
  • FIG. 17 illustrates, by way of nonlimiting example, an oscillating locking piece 93 at rest, the simplicity of which is similar to the previous one.
  • This part 93 has a sector-shaped clearance 94 opposite the opening 95 of which there are two pins 96, 97 belonging respectively to each of the two frame extensions 98, 99.
  • a movement in direction H of one of these pawns communicates by encountering an edge of the clearance such as 101, an angular movement of direction J to the piece 93 thus bringing its periphery 102 opposite the other pawn, so that the movement in the same direction of the frame associated with the latter is prevented and vice versa using the edge 101a and the periphery 102a.
  • a return spring can be used to give the part 93 a rest position shown.
  • a groove 103 placed in an adjusted manner between two lateral cheeks 104, 105 of the piece 93 to provide, on the one hand, a transverse support and, on the other hand, a bearing effect by the cooperation of a central core 106 with the rounded bottom 107 of a notch 108 placed in a central wall 109 dividing in two a central cavity 110.
  • cheeks are here also equipped with radial bosses such as 111, 112 to cause, as previously, displacements of elastic blades each carrying a movable contact of an opening switch.
  • a drawer 161 sliding on a central partition 162 on which it sits astride and visible in FIG. 19, whose opposite ends 163, 164 are cut in a bevel so as to transform into rectilinear transverse displacements -J- or -K- sliding contacts which they receive from one of the two pins 165, 166, movable in direction F, and belonging respectively to, or integral with, each of the armatures 167, 168.
  • Each of these displacements brings under the pin which has not been moved, an abutment surface 169a, 169b preventing any subsequent movement of the armature to be locked.
  • Two flexible reed switches 171, 172 can here again cooperate with the moving part, in particular with two transverse and opposite cleats such as 173, 174 to each interrupt the supply circuit of the coil which was not energized first .
  • the flexible blades can be used to give the drawer a central rest position which is visible in FIG. 19, see also FIG. 20.
  • this common terminal 130 takes a particular shape 140 which can be produced in a single piece with switch elements 141, 142 one carrying a fixed contact 143, and the other one end of a movable flexible blade 144; in order to avoid the delicate handling which accompanies the use of long flexible wires, each of the cooperating and opposite elements 145, 146 can also be provided with switches, an extension 147, 148 which extends to the vicinity of the associated coil 151, 152 where the end of a coil winding wire can be directly connected to it, for example by soft welding 153, respectively 154.
  • the carcass 156 of the coil 157 has a first terminal 158 which is accessible from the outside of the housing 159 and which is directly connected to one end 155 of the winding, while the second end 161 of this winding is extended (by a flexible or rigid conductor) to an input terminal 162 of the switch 163a, respectively 163b; an output terminal 164 of this same switch is, for its part, electrically connected (by a flexible or rigid conductor) to a second terminal 165 located on the carcass and serving as a wiring relay for an external cable 166a, respectively 166b used for current return.
  • the two second terminals of the coils can also be electrically connected either to each other to receive a single return conductor serving the two coils, or separately if the need arises.
  • All three, or four terminals for connecting the coils will advantageously be arranged on the same external face 167, respectively 168 of the device 1, respectively 160.
