  • the present invention relates to a microwave reversing relay of the type comprising three fixed coaxial contacts including one central contact, two rigid contact blades each capable of coming to bear alternately on the central contact and one of the two other coaxial contacts, l other blade then coming to bear against a ground plane, each of said contact blades being integral with an insulating plunger and each of the plungers being pushed back in translation by a leaf spring under the effect of a magnetic pallet with two branches capable of tilting around a central axis, in particular under the action of an electromagnetic motor.
  • the electromagnetic motor for example of the monostable type, advantageously comprises an induction coil, the magnetic core of which is arranged directly above the pivot axis of the pallet, and a column of magnetic material, one end of which is opposite. one of the branches of the pallet and the other end of which is connected by a magnetic plate to the core of the coil.
  • the motor can comprise a permanent magnet secured to a polar mass placed opposite the other branch of the pallet, a magnetic connecting plate ensuring a passage of magnetic flux from the magnet into the core of the coil and in the column opposite the first branch of the pallet, the flux created by the magnet in the core of the coil being in the opposite direction to the flux created in the core by the electrical excitation of the induction coil.
  • Return springs are usually provided for this purpose against the force of which the pushers are pushed back by the pallet and which serve to press the contact blades integral with the pushers against the ground plane.
  • Coaxial microwave reversing relays of the type mentioned have the drawback of requiring significant energy to ensure sufficient contact pressure of the contact blade associated with the switched channel with the central contact and the contact of the switched channel, in order to obtain good transmission and sufficient contact pressure of the contact blade associated with the non-switched track with the ground plane in order to ensure good insulation.
  • This last pressing pressure in fact depends on the restoring force of the springs on which the pushers are supported, restoring force which, on the contrary, must be overcome by the pushbutton during its movement under the effect of the actuation of the relay motor. .
  • the present invention proposes to produce a microwave coaxial reversing relay of simple mechanical design, avoiding the use of return springs and requiring only low energy consumption to ensure the passage from a switching position to the other.
  • the relay according to the invention is characterized in that the leaf spring is fixed in its central part to a projection arranged directly above the central coaxial contact, said leaf spring comprising on either side of its central part , means for fixing said pushers, and that the pallet comprises means for, during its tilting, exert a support on said leaf spring in the vicinity of the ends thereof.
  • the pallet has at its ends rod-shaped extensions each comprising a means of support on the leaf spring, for example a glass bead.
  • each of the pushers comprises for its fixing to the leaf spring a retaining groove, said leaf spring comprising for the positioning and fixing of each of the pushers a hole of diameter corresponding to that of the pushbutton extended by a longitudinal slit.
  • the groove in each pusher present in the longitudinal direction, in the position of retained on the leaf spring, a central part of narrowed section widening towards the ends, thus allowing a certain elastic movement of the leaf spring relative to the pushers, when the pallet is pressed on the leaf spring .
  • the leaf spring has a central orifice for its engagement on a projection forming part of an insulating plate, preferably made of molded plastic material, arranged on the plane of mass and comprising orifices for the passage of the pushers, and means for supporting the pivot axis of the pallet.
  • the plate also has the holes necessary for the passage of the relay assembly screws.
  • the plate further comprises on its face opposite to that supporting said projection, insulating pins, preferably molded in one piece, crossing the ground plane and serving for the vertical guidance of the rigid contact blades each advantageously fixed to the end of each plunger opposite to that by which it is fixed to the thrust leaf spring.
  • the ground plane distinct from the insulating plate, can be easily produced by cutting out a thin metal plate.
  • the coaxial relay conventionally comprises a basic block 1, on which are mounted three coaxial contacts, namely a common central contact, 2, and two lateral contacts 3 and 4.
  • an electromagnetic motor comprising a core 6 made of magnetic material, preferably of pure iron, on which is mounted an induction coil 7 connected to a source of electric current and creating, when 'it is excited, a magnetic flux in the nucleus.
  • the relay motor further comprises a column, made of magnetic material, preferably of pure iron, 8, and a polar mass, also of pure iron, 9, supporting a permanent magnet 10, the circuit of the relay motor being completed by a magnetic plate, also made of pure iron, 11, providing a magnetic flux link between the magnet 10, the core 6 of the coil and the magnetic column 8.
