Definitions

  • the present invention relates to a device for resiliently maintaining a contact bridge
  • a device for resiliently maintaining a contact bridge comprising an insulating contact carrier, provided with a column having externally on its top a bearing surface on which an internal housing capable of receiving opens.
  • a pressure spring in support, a pressure spring, a movable contact bridge, a central surface of which is placed opposite the support surface and which admits, relative to a so-called longitudinal direction defined by contacts cooperating during movement of said bridge to establish an electrical connection, a plane of symmetry, and a U-shaped coupling stirrup whose parallel branches, provided with hooks and connected to a common cross-member, surround the contact bridge to communicate a bearing force on it fixed contacts by means of an elastic blade which is placed on this contact bridge and the central part of which is folded so as to produce a re-entrant angular shape s e approaching deck and intended to cooperate with the stirrup.
  • Such holding devices are, in particular, used to effect elastic holding of the contact bridges of electromagnetic contactors.
  • a known contact bridge holding device US-A-3 740 510
  • curved hooks of the stirrup engage on a mobile coil placed at the end of the spring, while the common crosspiece is applied via an elastic blade to the surface of the contact bridge.
  • this continuous crosspiece has a centering rib which cooperates with a reentrant shape to maintain the elastic blade, it is not convenient to communicate by pressure to the central region of this blade, a deformation allowing the reentrant shape d 'escape the rib, deformation which is necessary to operate the disassembly or replacement of a contact bridge.
  • a stirrup has two branches which pass inside a contact pressure spring, and whose curved ends cooperate with a support washer intended to receive the turn spring mobile; this device does not allow an easy assembly insofar as this washer must be put in place when the spring is placed in the housing of the contact carrier, and that its introduction into this housing is done in a direction opposite to that which must take the stirrup to enter this same housing.
  • a switch comprising a contact lever mounted to tilt on a rotary support structure. The connection between these two parts is then ensured by means of a stirrup subjected to the action of a spring and the two ends of which are provided with hooks which engage in two respective grooves formed in a thickening of the contact lever.
  • the invention proposes to provide an elastic contact bridge holding device in which measures are taken to facilitate disassembly of the contact bridge without altering the convenience of assembling the contact carrier in the factory.
  • This contact bridge 12 cooperates with fixed contacts 13, 14 to form a power switch 15 which is housed in a cell 16 belonging to a series of parallel cells disposed in an isolation box 17 fixed on the body.
  • the column 9 is traversed by a housing 18 which extends over its length and which opens by an upper opening 19 on a bearing surface 20 and by a lower opening 21 in a cavity 22 which receives the armature.
  • This housing 18 has two transverse widths so as to form a shoulder 23 which is directed towards the cavity 22 and on which rests a fixed turn 24 of a contact pressure spring 25; the movable turn 26 of this spring in turn rests on a cross member 27 of a stirrup 28 having two parallel branches 29, 30 which give it the general shape of a U - see FIG. 2.
  • the stirrup 28 is located partly in a lower portion 31 of the housing 18 which receives the spring and partly in an upper portion 32 of this housing.
  • the contact bridge 12 which is shown in FIG. 1, in the closed position of the switch 15, takes the form of a bowl having a bottom 37, two side walls 38, 39 and two arc horns 40, 41; the movable contact pads 42, 43 are arranged on the outer surface of the bottom 37, while the interior volume 44 of the bowl receives an elastic blade 45.
  • This elastic blade has two ends 46, 47 which rest on the bottom at vicinity of the arc horns, and a domed central region 48 which has a re-entrant angular shape 49.
  • the contact bridge 12 is placed between the legs 29, 30 of the stirrup - see FIG. 2 - so that the hooks 35, 36 engage in the re-entrant angular shape 49 of the elastic blade; a contact pressure force developed by the compression of the spring 25 is therefore transmitted to the contact bridge 12 by the stirrup 28 and by the elastic blade 45.
  • FIG. 1 shows that the cross member 27 of the metal stirrup 28 is placed in the vicinity of the frame 5; it is therefore necessary to interpose between these two pieces of isolation means to prevent the birth of leakage currents or arcs which would tend to be established between two neighboring switches via the frame.
  • the means used are represented by an isolation piece 50 - see also FIG. 2 - of which a boss 51 penetrates into the lower portion 31 of the housing 18 which rests on the frame, and which is capable of serving as a stop for cross 27.
  • the disassembly of a contact bridge 12 can be carried out, for example, when the contact bridge is pressed on the fixed contacts.
  • pressure in the direction G is exerted between the hooks and in the interval 60 using a simple tool on the central region of the elastic blade 45 (and, in particular, on the bottom 57 of the re-entrant angular shape 49) to deform this blade and allow this re-entrant angular shape to escape the hooks; the evacuation of the contact bridge is then effected by a lateral thrust exerted in direction F.
  • the upper surface 57 of the re-entrant angular shape 49 of the elastic blade 45 has been given the shape of a very open V in the plane PP ', see FIG. 3.
  • the two hooks which themselves have a V-shaped shape capable of cooperating with the re-entrant angular shape 49 to operate lateral support of the contact bridge in the direction G, each have an edge 58 which cooperates with the bottom 57 of the angular shape re-entrant and which is more inclined towards the longitudinal plane of symmetry QQ 'of the contact bridge 12 than the cooperating branch of the section of the elastic blade 45 by the plane PP'.
