  • the N magnets 23a, 23b, 23c, 23d are fixed against the inner wall of the body 11 of the cylinder head 10. They are for example of parallelepipedal shape to simplify their manufacture and can be positioned and maintained by various conventional means, such as parts plastic holding or wedging (not shown in the figures) and the shape arrangements of the inner wall of the cylinder head 10.
  • the magnetization axes of the N magnets 23a, 23b, 23c, 23d lie in a plane perpendicular to the X axis and are indifferently either all directed to the X axis, or all directed away from the X axis.
  • the N concentrator elements 43a, 43b, 43c, 43d are made of ferromagnetic material and are fixed against the inner wall of the magnets 23a, 23b, 23c, 23d, between the magnets and the coil 20. In the embodiment shown, they have a parallelepiped shape and are also held in place by various conventional means of wedging.

  • the core 30 When the actuator is in the engaged state, the core 30 is movable in translation (arrow T) along the longitudinal axis X under the action of the coil 20 between the open and closed positions.
  • the actuator is designed so that these two positions are stable and it is necessary to reverse the direction of the control current flowing in the coil 20 to move from one to the other position.
  • Returning means such as a return spring 50 placed between the movable core 30 and any fixed support of the apparatus (see figure 6 ), are also provided to facilitate a translational movement of the core 30, in the closed position to open position.
  • the actuator has drive means 51 in translation, which enable the movable core 30 to drive a movable slide 52, but only during its translational movement T.
  • the drive means 51 comprise a pivot connection 51 placed between the movable core 30 and the slider 52.
  • This pivot connection 51 drives the slider 52 which itself drives a movable bridge 53 carrying the movable contact or 58 of each pole power of the device.
  • a contact pressure spring 55 positioned between the movable bridge 53 and the slider 52 makes it possible to press the movable contacts 58 onto the corresponding fixed contacts 59 of the power pole in the closed position.
  • the actuator is designed so that, in the closed position (see figures 1 & 3 ), the upper ends of the concentrator elements 43a, 43b, 43c, 43d are opposite the polar surfaces 33a, 33b, 33c, 33d of the upper plate 31. Similarly, the polar surfaces 34 of the lower plate 32 are opposite lower flanges 14 of the cylinder head 10. A magnetic flux B coming from the magnets 23 can therefore flow in the actuator, by going along the following path: magnets 23, concentrating elements 43, polar surfaces 33 of the upper plate 31 of the core 30, barrel central 39, polar surfaces 34 of the lower plate 32, lower flanges 14 of the yoke 10, body 11 and magnets 23.

  • the lower ends of the concentrator elements 43a, 43b, 43c, 43d are next to the surfaces
  • the magnetic flux B from the magnets then travels the following path: magnets 23, concentrator elements 43, polar surfaces 34 of the lower plate 32 of the core 30, central shaft 39, polar surfaces 33 of the plate upper 31, upper flanges 13 of the yoke 10, body 11 and magnets 23.
  • the actuator has one or more pieces 19 of non-magnetic material, such as bronze or plastic. These parts 19 have the form of plates or rings and are positioned for example against the inner face of the flanges 13, 14 (see Figures 1 & 2 ), but could also be positioned on the ends of the concentrator elements 43 or on the polar surfaces 33,34.
  • the core 30 is also rotatable (arrow R) about the longitudinal axis X under the action of a mechanical trigger device.
  • This triggering device can be indifferently manual or motorized depending on the type of switch device to which the actuator is intended.
  • the rotational movement allows the actuator to move from an engaged state (indicated in figure 3 ) to a triggered state (indicated in figure 4 ).
  • the amplitude of the rotational movement between the engaged state and the triggered state is preferably approximately 1 / 2N turn around the X axis.
  • Conventional mechanical stops make it possible to limit the rotational stroke of the core 30 to the desired value.
  • the pivot connection 51 is designed so that the rotational movement of the core 30 does not alter the position of the slider 52 and therefore does not cause the movable contacts 58.
  • the polar magnetic surfaces 33, 34 formed by the advances of the plates 31, 32, have, in the engaged state, large magnetic contact surfaces S positioned either opposite the flanges 13 or 14 of the cylinder head 10 or facing the one or other of the ends of the concentrator elements 43, allowing the passage of the magnetic flux.
  • the magnetic flux B generated by the magnets can circulate with minimum air gaps and create a magnetic holding force F which is proportional to the contact surfaces S and the square of the flow B.
  • the pole surfaces 33,34 will no longer be aligned with the concentrator elements 43 or with the flanges 13,14, so that the contact surfaces S will decrease rapidly.
  • the magnetic retention force F applied to the core 30 will thus also decrease rapidly.
  • the actuator After a rotation of about 1 / 2N turn (see figure 4 ), the actuator is in the triggered state.
  • the polar surfaces 33a, 33b, 33c, 33d, 34 are now substantially opposite the notches 17 of the yoke 10 and therefore completely offset from the N concentrating elements 43a, 43b, 43c, 43d, N edges 13a, 13b, 13c, 13d and N edges 14, creating very important air gaps.
  • the flanges 13, 14 and the concentrator elements 43 are substantially aligned with the notches 37 of the core 30.
  • the corresponding magnetic contact surfaces S are therefore eliminated and the magnetic retention force F applied to the core 30 is also practically zero. .
  • the return force, generated by the return spring 50, is calculated to be less than the holding force F when the actuator is in an engaged state, which gives stable open and closed positions even in the absence
  • the holding force F has practically disappeared and the only force applied in translation to the movable core 30 remains the restoring force exerted by the return spring 50 (FIG.
  • Auxiliary increase of contact pressure springs 55 so that the movable core 30 is automatically translated in translation to the open position causing the opening of the movable contacts 58.
  • the size of the spring 50 does not need to be very important to ensure this function, which contributes to the compactness of the device, because it has only a residual effort to fight in the triggered state.
  • the triggered state therefore guarantees maintaining the open position and therefore the separation of the contacts as would a separate lock that would act on the mobile contacts autonomously.
  • the actuator is preferably provided with friction reduction means which appear during the rotational movement of the core 30.
  • these friction reduction means may be composed in particular by the rings or plates 19 previously described to maintain residual air gaps in open and closed positions.
  • These pieces 19 are therefore chosen in a non-magnetic material which also makes it possible to reduce the frictional forces of the moving core 30 during its rotational movements, such as bronze or teflon.
  • the parts 19 may also comprise only such an anti-friction coating.
  • Other additional means may be used to reduce the friction of the movable core (grooves in the frame of the coil, etc.).
  • the number N is at least equal to two to obtain in particular a good distribution of the forces in the mobile core 30. This then makes a rotation of about 1/4 turn around the X axis between the engaged state and the triggered state.
  • the outer yoke 10 may be made of two identical and symmetrical parts with respect to X, each part having an approximate shape of C and comprising an upper rim 13, a body 11 and a lower rim 14, as suggested in FIG. figure 1 .
  • the actuator then has a substantially parallelepipedal overall shape which is advantageously very compact and simple to produce.
  • the number N is equal to four and the movement of the rotating core is about 1/8 of a turn. In this case, the stroke of the rotational movement necessary to reach the triggered state is advantageously very short.
  • the body 11 of the yoke 10 is then preferably cylindrical as shown in the figures. However, according to another variant, the body of the yoke may also have a polygonal structure having N facets in a transverse sectional plane.
  • N is also possible, as for example N equal to three.
  • all the different parts of the actuator three in number are then spaced about 120 ° between them around the axis X.
  • the electromagnetic actuator described in the invention simultaneously performs the functions of closing and opening the power pole contacts by virtue of its translational movement between two stable positions and the triggering and interlocking functions of a lock. thanks to its rotational movement. It is robust enough to be used in low voltage or medium voltage devices.
  • An electrical switch device comprising such an actuator will then have the distinction of being more compact, lighter, simpler to manufacture (less parts to assemble) and therefore more economical than a conventional device with a separate lock.
  • Such an apparatus will also not require having a permanent energy reserve (with for example capacities), capable of separating the contacts movable in a safe way even if it is impossible to supply a control current in the coil.
