Definitions

  • the object of the invention is to provide a device operated by a contact tiltable bistable, and easily configurable as an electromagnetic relay from of a standard structure of a remote control switch.
  • control member comprises an articulated connecting rod on the pallet and the pendulum to form a permanent direct link, the point of articulation of the rod on the balance being offset relative to the axis of tilting.
  • the elastic return device comprises a pair of compression springs acting on the underside of the pallet, and extending parallel to each other and to the rod in a direction substantially perpendicular to the pallet, the two springs having characteristics of different length and stiffness, one of the springs acting before the other.
  • a contact position indicator is integrated inside the manually operated test button.
  • the indicator is composed of an optical prism cooperating with a probe integral with the pallet, the probe having two signaling marks arranged alternately opposite the inclined face of the prism according to the position drawn or moved away from the pallet.
  • FIG. 1 is an elevation view of the electromagnetic relay according to the invention, shown in the OFF position when the electromagnet is not supplied.
  • Figure 2 is an identical view to Figure 1, the relay being equipped with a device additional with test button and contact position indicator.
  • Figure 3 is a sectional view along line 3-3 of Figure 2.
  • Figure 4 shows a partial view of Figure 2, showing the indicator in ON position of the relay following energization of the electromagnet.
  • Figure 5 is a sectional view along line 5-5 of Figure 4.
  • Figure 6 shows a partial view of Figure 2, after pressing the button test.
  • Figure 7 is a sectional view along line 7-7 of Figure 6.
  • the changeover relay 10 is housed in a housing 12 in molded insulating material containing an electromagnet 14, a control mechanism 16, and an electrical power circuit 18 having a movable contact 20 tilting cooperating with two fixed contacts 22, 24.
  • the fixed contact 22 is connected to a first terminal 26, and the other fixed contact 24 of the change-over relay 10 is connected to a second terminal 28, the two terminals 26, 28 being located on the same side of the case 12.
  • the movable contact 20 is equipped with a contact arm 30 pivotally mounted on a articulation 32 with knife, arranged at the end of a rigid conductor 34, of which the other end is connected to a third terminal 36.
  • the contact arm 30 is associated with a spring 38 in the form of an elastic blade making the movable contact 20 bistable.
  • the third terminal 36 is located opposite the other two terminals 26, 28.
  • the electromagnet 14 comprises a ferromagnetic pallet 38 pivotally mounted on the left side of the cylinder head 40, and a biasing spring 42 cooperates with the pallet 38 in the vicinity of the articulation zone 43 to ensure minimum clearance during the pivoting movement.
  • the control mechanism 16 comprises a balance 44 pivotally mounted on an axis 46 fixed between two extreme angular positions, and a connecting rod 48 articulated at one of its ends on the pallet 38, and at its other end on the balance 44.
  • the articulation point 50 of the link 48 on the balance 44 is offset from the tilting axis 46.
  • the pendulum 44 has a U-shape having a central recess 52 in which is engaged the end of the contact arm 30.
  • the pallet 38 moves the pendulum 44 from one position to the other at each operation cycle of the pallet 38 depending on whether the electromagnet 14 goes from the excitation state to the rest state, or vice versa.
  • the pallet 38 In the idle state of the electromagnet 14 corresponding to the absence of excitation of its coil, the pallet 38 is kept apart from the pole surface 54 of the cylinder head 40 thanks to an elastic return device 56 arranged between the housing 12 and a portion of the palette.
  • the return device 56 comprises a pair of springs 58.60 compression bearing on protrusions 62 of the housing 12, and acting directly on the underside of the pallet 38 in the spacing direction.
  • the movable contact 20, is in abutment against the upper fixed contact 24 in the position shown in Figure 1.
  • the two springs 58, 60 extend parallel to each other in a direction perpendicular to the pallet 38.
  • the pallet 38 When the electromagnet 14 is energized, the pallet 38 is attracted against the surface pole 54, and the link 48 causes the rocker 44 to tilt so as to drive the movable contact 20 to the fixed contact 22 lower.
  • the modulation of the return force by the two springs 58, 60 allows an optimal accumulation of the excess energy supplied by the electromagnet 14 during the attraction of the pallet 38.
  • the spring 58 on the left located between the articulation zone 43 of the pallet 38 and the other spring 60 on the right, is used to detach the contacts 20, 22 when the arm of contact 30 pivots anti-clockwise.
  • Spring 58 le shorter has a higher hardness than the longer spring 60.
  • the relaxation of first spring 58 on the left is used to break the micro-welds, while the other spring 60 on the right ensures the complete spacing of the pallet 38, and the tilting of the movable contact 20 towards the other stable state pressing against the contact fixed 24 upper.
  • Figures 2 to 5 show the change-over relay 10 of Figure 1 additionally equipped a test button 70 in front of which an indicator 72 for the position of the contacts 20, 22; 20, 24.
  • the manually operated test button 70 passes through an orifice 74 passage formed in the front face 76 of the housing 12, and is used to actuate mechanically the pallet 38 in the direction of approximation with the pole surface 54, so as to transmit a rocking movement to the balance 44, and from this changes the state of the moving contact 20 following each depression of the test button 70.
  • an optical prism 78 cooperating with a position probe 80 integral with the pallet 38.
  • the probe 80 carries a first colored marker 82 which moves in translation along the prism 78 while occupying two extreme positions depending on the location of the pallet 38.
  • test button 70, the prism 78, the probe 80 and a return spring 86 are mounted in a support 88 secured to the housing 12.
  • the support 88 carries a second color marker 84 different in color from the first marker 82.
  • the contacts 20, 22 of the first series of contacts are open, and the other contacts 20, 24 of the second series are closed.
  • the first benchmark 82 of the probe 80 is arranged opposite the inclined face of the prism 78, which reflects the coloring of the first marker 82 towards the head of the prism 78.
  • test button 70 is not pressed, and permanently protrudes by the action of the return spring of the type compression 86.
  • the manual depressing of the test button 70 in the orifice 74 causes the forced tilting of the rocker 44, and the change of state contacts.
  • the signaling given by the indicator 72 is not correct, but remains invisible since the operator hides the prism head 78 as long as his finger pushes on the test button 70.
  • indicator 72 and the test button 70 could be arranged differently without departing from the scope of the invention.
  • a variant consists in particular of use an elongated prism and a probe with two different color markers. When the electromagnet is activated the indicator moves and shows its second color 92.
