Definitions

  • the present invention relates to an electromagnetic relay with two armatures, of the type comprising a coil provided with an axial core forming a magnetic circuit with a yoke parallel to the coil and with these two armatures each cooperating with one end of the core for actuating movable contacts. separate.
  • the present invention aims to achieve a relay in which the synchronization of the movement of the armatures presents no risk of defect.
  • the electromagnetic relay comprises, in a housing, a coil provided with an axial core forming a magnetic circuit with a yoke parallel to the coil and with two movable magnetic armatures each cooperating with one end of the core, each of these armatures actuating at least one movable contact cooperating with at least one fixed contact. It is characterized in that each armature is produced substantially along an L, a first branch of which is constituted by a magnetic pallet transverse to the coil, and the second branch of which extends along the cylinder head, and in that means for cooperation are provided at the respective ends of the two second branches, so that any movement from one armature is communicated to the other.
  • each armature has, at the end of its second branch, fingers which mesh into fingers complementary to the second branch of the other armature.
  • the aforementioned meshing has a predetermined clearance allowing the movement of the frames.
  • the frames are joined by the free ends of their second branches to form a single part, this part being produced, at least in the junction zone, by a flexible material.
  • the material must be flexible enough to stretch slightly during the rotary movement of the two frames, as well as to flex under the effect of the combined rocking movements of these frames.
  • the frames include a plastic part overmolded on two magnetic pallets.
  • This embodiment makes it possible to obtain a sharp angle which precisely defines the axis of rotation without depending on a bending radius of curvature.
  • the relay comprises, in a plastic casing 1, a coil 2 provided with an axial core 3 forming a magnetic circuit with a yoke 4 external to the coil 2.
  • the core 3 opens out each end of the coil by pole shoes 5 intended to cooperate with armatures 6 arranged symmetrically.
  • These frames are L-shaped and have a first branch constituted by a magnetic pallet 7, transverse to the coil and overmolded in a second branch 8 of non-magnetic material extending along the yoke.
  • the mounting of the frames allows them to oscillate around a point 9 located in the hollow of the L and at the end of the cylinder head 4.
  • the second branch 8 of the frame comprises, on its outer part, bosses 11 for cooperating with two movable contacts 12 each consisting of a flexible blade 13 carrying at its end a contact piece 14.
  • the relay therefore comprises two pairs of movable contacts 12 each cooperating with a pair of fixed contacts 15.
  • These fixed contacts like the fixed supports 16 of the flexible blades 13, are formed by folds of conductive bars, such as 17 embedded in the within the walls of the housing 1 (Fig. 2) and exiting at the in part of the relay to form connections 18 which also include the connections of the coil 2.
  • Each frame 6 comprises, at the end of its second branch 8, two fingers 19a, 19b substantially extending this second branch and located at different levels.
  • the finger 19a is located at an upper level and the finger 19b at a lower level.
  • the two armatures 6 being identical and arranged head to tail in the relay, the finger 19a of one will be opposite the finger 19b of the other, and vice versa.
  • the projecting lower part of the fingers is housed in a cavity 21 formed in the cylinder head 4.
  • the invention thus makes it possible to have four reversing contacts with synchronized operation.
  • the frames 106 are joined by the ends of their second branches 108 so as to form a single piece. More specifically, these are the plastic parts of the frames which are thus joined together, the overmolded pallets 107 remaining distinct.
  • the second branches 108 are thinned towards the junction point 109 which is in the form of a very thin plastic veil, presenting practically no resistance to bending.
  • the plastic used can stretch slightly where it is thinner to provide the equivalent of longitudinal play.
  • the object of the invention is achieved, namely to obtain an almost perfect synchronism of the movement of the reinforcements.
  • each pallet 7 can carry movable contacts 12 arranged parallel to the plate 7.
