Definitions

  • the object of the invention is to provide a device operated by a bistable tilting contact, and easily configurable as an electromagnetic relay from a standard structure of a remote control switch.
  • control member comprises a connecting rod articulated on the pallet and the balance to form a permanent direct connection, the point of articulation of the rod on the balance being offset with respect to the pivot axis .
  • 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 link in a substantially perpendicular direction on 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 controlled test button.
  • the indicator is composed of an optical prism cooperating with a probe secured to the pallet, the probe having two signaling pins arranged alternately opposite the inclined face of the prism depending on the position attracted or moved away from the pallet.
  • Figure 1 is an elevational 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 an additional device with test button and indicator of the position of the contacts.
  • 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 the ON position of the relay following the excitation 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 test button.
  • Figure 7 is a sectional view along line 7-7 of Figure 6.
  • the change-over relay 10 is housed in a housing 12 made of molded insulating material containing an electromagnet 14, a control mechanism 16, and an electric 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 housing 12.
  • the movable contact 20 is equipped with a contact arm 30 pivotally mounted on a knife joint 32, arranged at the end of a rigid conductor 34, the other end of which is connected to a third terminal 36.
  • the arm contact 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 part 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 play during the movement of pivoting.
  • the control mechanism 16 comprises a balance 44 pivotally mounted on a fixed axis 46 between two extreme angular positions, and a connecting rod 48 for articulation 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 pendulum 44 is offset with respect to the pivot axis 46.
  • the pendulum 44 has a U-shape having a central recess 52 in which the end of the contact arm 30 is engaged.
  • the pallet 38 moves the pendulum 44 from one position to the other at each operating cycle of the pallet 38 depending on whether the electromagnet 14 passes from the excitation state to the rest state, or vice versa.
  • the pallet 38 In the state of rest 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 yoke 40 by means of an elastic return device 56 arranged between the housing 12 and a portion of the palette.
  • the return device 56 comprises a pair of compression springs 58, 60 bearing on protrusions 62 of the housing 12, and acting directly on the underside of the pallet 38 in the direction of separation.
  • the movable contact 20 is in abutment against the upper fixed contact 24 in the position shown in FIG. 1.
  • the two springs 58, 60 extend parallel to one another in a direction perpendicular to the pallet 38.
  • the pallet 38 When the electromagnet 14 is energized, the pallet 38 is attracted against the pole surface 54, and the link 48 causes the rocker 44 to tilt so as to drive the movable contact 20 towards the lower fixed contact 22.
  • 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 contact arm 30 pivots counter-clockwise. a watch.
  • the shorter spring 58 has a higher hardness than the longer spring 60.
  • the trigger of the first spring 58 on the left is used to break the micro-welds, while the other spring 60 on the right ensures the complete separation of the pallet 38, and the tilting of the movable contact 20 towards the other stable state in press against the upper fixed contact 24.
  • Figures 2 to 5 show the changeover relay 10 of Figure 1 equipped in addition to a test button 70 in front of which moves an indicator 72 of the position of the contacts 20, 22; 20, 24.
  • the manually-operated test button 70 passes through a passage orifice 74 formed in the front face 76 of the housing 12, and serves to mechanically actuate the pallet 38 in the direction of approach with the pole surface 54, so as to transmit a rocking movement at the balance 44, and therefore a change in state of the movable contact 20 following each pressing of the test button 70.
  • an optical prism 78 cooperating with a feeler 80 of position integral with the pallet 38.
  • the feeler 80 carries a first colored marker 82 which moves in translation along the prism 78 in two positions extremes depending on the location of the pallet 38.
  • test button 70, the prism 78, the feeler 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 of coloring different 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 marker 82 of the feeler 80 is arranged opposite the inclined face of the prism 78, which reflects the coloration of the first marker 82 towards the head of the prism 78.
  • the magnetic attraction of the pallet 38 against the cylinder head 40 causes the probe 80 to descend.
  • the second mark 84 of different coloring is found in the vicinity of the inclined face of the prism 78, followed by the reflection of the light beam towards the front face.
  • test button 70 is not actuated, and remains permanently protruding by the action of the return spring of the compression type 86.
  • test button 70 With reference to FIGS. 6 and 7, manual insertion of the test button 70 into the orifice 74 causes the rocker 44 to be forcibly rocked, and the state of the contacts to change.
  • the signaling given by the indicator 72 is not correct, but nevertheless remains invisible since the operator hides the head of the prism 78 as long as his finger pushes on the test button 70.
  • a variant notably consists in using an elongated prism and a probe having two markers of different colors. When the electromagnet is activated, the indicator moves and shows its second color 92.
