Definitions

  • the present invention relates to a multipolar switching device according to the preamble of claim 1 (see for example EP-A-0058235) with partially fugitive action.
  • It relates more particularly to a device of the type comprising a plurality of switches each comprising at least one fixed contact element cooperating with at least one mobile contact element carried by a mobile assembly common to all the switches, this movable assembly being able to be moved, by a control mechanism, between two positions, at the end of a stroke causing a change of state of at least part of the switches.
  • movable contact elements which consist of movable contact bridges are mounted on a movable assembly presented under the shape of a "rake" constituted by an insulating support pierced with identical rectangular openings, staggered side by side and in each of which is engaged transversely a movable contact bridge.
  • the moving assembly is produced in the form of a rigid assembly, usually in one piece, capable of driving in translation, synchronously and permanently, all of the movable contact bridges. , to ensure the closing or opening of the electrical contacts.
  • the contact pressure between the contact bridges and the fixed contact elements is then ensured by means of a coil spring housed in each opening of the rake and placed in support of the movable contact bridge passing through this opening.
  • the invention therefore more particularly aims to provide a switching device capable of solving the problems mentioned above thanks to a particularly well suited switching sequence.
  • the invention provides a switching device comprising, housed in the same housing, at least one switch provided with at least one fixed contact element and one movable contact element urged on by a movable assembly, and a control member capable of ensuring the actuation of the mobile assembly.
  • this device is characterized in that said control member is connected to the movable assembly of the switch via a mechanical connection comprising a disengageable coupling capable of passing into the disengaged position during the outward stroke of the control member when the resistant force exerted by the moving element rises above a determined threshold, then to return again to the engaged position at the end of the return stroke of the control member .
  • the above disengageable coupling can comprise two magnetically coupled parts. However, it can be achieved using elastic latching means.
  • the auxiliary switch module shown in solid lines in Figures 1 to 3, involves, housed in a substantially rectangular housing 1 supporting four pairs of fixed contact elements F1, F′1 - F2, F′2 - F3, F ′ 3 - F4, F′4, a mobile assembly in the form of a rake 2.
  • On the rake are mounted four mobile contact bridges P1, P2, P3, P4 which cooperate respectively with the pairs of fixed contacts F1 , F′1 - F2, F′2 - F3, F′3 - F4, F′4 to form four switches I1-I4.
  • the rake 2 is produced in the form of a flat insulating support, pierced with identical rectangular rectangular openings O1 to O4, staggered side by side, in each of which is engaged a movable contact bridge P1 at P4.
  • each movable contact bridge is constituted by a bar 3 carrying in bridge, on its upper face, two movable contacts 4, 5 which cooperate with an alignment of two fixed contacts F, F ′ located on either side of the rake 2.
  • This bar 3 is, moreover, biased by a compression spring R bearing on the underside of the opening O.
  • the rake 2 comprises, in its upper part, a coupling member 6 (of T-shaped section) which is intended to be connected, in a conventional manner, to a connection element integral with the mobile assembly of a contactor. Thanks to this coupling, the rake 2 is driven in translation by a driving member of the contactor so as to ensure, on the one hand, the closing of the auxiliary electrical contacts with a suitable pressure determined by the springs R and, on the other hand, opening of these contacts.
  • the switch I1 is of the opening type and the switches I2-I4 of the closing type, while the pair of fixed contacts F1, F′1 associated with the contact carrier P1 is offset with respect to the pairs of fixed contacts F2, F′2 - F3, F′3 - F4, F′4 associated with movable contact carrier P2, P3, P4, along the axis of movement of the rake 2.
  • the switches I1-I4 respectively associated with the two parts 7, 9 of the rake can be of the same type, for example closing , or the switch I1 can be closed and I2-I4 open.
  • the two parts 7, 9 of the rake 2 are coupled to each other in a disengageable manner by means of a permanent magnet 10 fixed, by means of a bracket 11, on the upper face of the part 9 situated opposite the 'transverse element 8, and a plate 12 of magnetizable material fixed, for example, by gluing to the underside of the transverse element.
  • the rake 2 At rest, the rake 2 is in a position such that it maintains the contact bridge P1 applied to the pair of fixed contacts F1, F′1 and the mobile contact bridges P2 to P4 spaced from the pairs of fixed contacts (F2, F′2 - F3, F′3 - F4, F′4).
  • the contacts F1, F′1 are opened at the end of the first period. In another application, it can be done during the second period.
  • switches of the auxiliary module which include the movable contact bridges P2 to P4, serve to ensure a pre-supply of a capacitive load supplied by means of a contactor on which is coupled the auxiliary module.
  • the opening switch comprising the contact bridge P1 then serves, when the contactor returns to rest, to actuate with an opening switch specific to the contactor a circuit for discharging the capacitive load.
  • the invention does not only apply to an auxiliary module.
  • FIG. 1 the concept of a rake 2 produced in two parts 7, 9 connected together by a disengageable coupling 10, 12 is applicable to the rakes used by the contactors themselves.
  • this contactor comprising a housing 14 containing an electromagnet 15 whose movable armature 16 is coupled to the rake 2.
  • each of the two parts 7, 9 of the rake 2 could include a different number of openings O and opening or closing contacts arranged at will in one or the other of the parts 7, 9.
  • the disengageable coupling can be produced differently.
  • the permanent magnet 10 could be associated, as shown in FIGS. 4 and 5, with a magnetic circuit 17 in the shape of a U, the extreme edges of which attract the plate 12.
