Definitions

  • the present invention relates to a bistable magnetic arrangement comprising, as the first magnetic member, a core surrounded by a coil, which can be remanently magnetized alternately by coil currents, and as the second magnetic member, the permanent magnet which takes the remanent-magnetizable core in its axial direction -Magnets, one of the magnetic members being alternately axially displaceable in one or the other of two end positions by reversing the coil current relative to the other.
  • the present invention has for its object to improve the bistable arrangement according to the preamble of the introduction to the description with regard to its response and drop behavior as well as its speed and reliability, to reduce material and energy expenditure by optimally utilizing the mechanical and electrical functions and parts, and the load capacity increase the order noticeably.
  • the coil body 2 with the remanently magnetizable core 3 rigidly fastened therein and of at least approximately the same length 4 and with the coil winding 5 is arranged in a fixed manner on the mounting plate 1.
  • a rectangular frame 6 made of non-magnetic material, preferably plastic, is displaceably mounted on the bobbin 2 by means of the plate-shaped arm 2b shown in dashed lines (2a) as a mechanical guide element.
  • the frame 6 has end walls 7, 8 and spacers 9, 10, on which bead-shaped slide rails or runners 11, 12 are formed; the spacers 9, 10 are longer than the coil body 2 or its core 3.
  • a permanent magnet 13, 14 is inserted into each of the end walls 7, 8, the surfaces of which opposite the core 3 of the coil 5 are parallel to the relevant pole face 16, 17 of the core 3 of the coil 5 and are perpendicular to the magnetic axis 20.
  • the height 19 of the permanent magnets 13, 14 is smaller than their diameter (thus they have the shape of circular disks) and more or less, depending on how much their coercive field strength is greater than that of the material of the core 3 of the coil 5; the permanent magnets 13, 14 are made of SECO (rare earth cobalt) and the core 3 of the coil 5 is made of ALNICO.
  • the frame 6 is, in addition to the plate-shaped arm 2b and the bead-shaped rails or runners 11, 12, which slide on the mounting plate 1 and the cover plate, not shown, especially by the strong magnetic field between the permanent magnets of the first and the second magnetic Limb as a result the force in between is kept in balance.
  • the magnetic axis 20 of the core 3 of the coil 5 is at least approximately identical to that of the permanent magnets 13, 14; in the position shown, the polarization of the permanent magnet 13 is opposite to that of the core 3 and that of the permanent magnet 14 is opposite to that of the magnet 13. In the position shown, an attractive force therefore occurs between the pole face 16 of the core 3 and the permanent magnet 13 opposite it, and a repulsive force occurs between the pole face 17 of the core 3 and the permanent magnet 14 opposite it.
  • the rod-shaped arm 21 is integrally formed on the frame 6 and transmits the movement of the frame 6 to a switching device to be controlled in a force-locking manner, as will be explained with reference to FIG. 2.
  • the guide tongue 22 for the two-armed lever 25 is integrally formed on the outside, which can be moved by hand parallel to the direction of movement of the frame 6 by means of the slide 24 accessible outside the housing wall 23.
  • One arm 25a of the lever 25 is guided on the guide tongue 22 by means of the guide lug 26 and is rigidly connected to the slide 24 by the connecting piece 28 guided in a slot 27.
  • the two-armed lever 25 can thus be displaced in two opposite directions by means of the slider 24 from the drawn central position parallel to the movement of the frame 6; in the direction to the left in the plane of the drawing, the frame 6 is shifted into a blocking position with the permanent magnet 14 in contact with the pole face 17 of the core 3, the other finger-shaped arm 2 resting against the end wall 8 of the frame 6.
  • the nose 31 equipped with a hemisphere 30 deflects the contact spring 32 so that the electrical contact with the contact spring 33 is interrupted; in the middle position of the slide 24, this is only the case if the frame 6 is in the position shown opposite.
  • the pair of contact springs 32/33 which could also be supplemented by a central contact spring for a changeover switch with a central position, is in the slots between the plastic blocks 34 integrally formed on the mounting plate 1 (in the middle). and 35, 36 (to the side thereof) and held in bores in the printed circuit board 37 by means of the interlocking connecting lugs 38, 39; By means of the stop pin 40, deflections are limited by the pretension.
  • An associated setting potentiometer 41 is also soldered onto the circuit board, which contains an electronic circuit arrangement required for the changes in the operating states.
  • the connecting terminals 61, 62, 63, on which the connecting conductors 64, 65 are inserted are inserted in columns between spacer blocks 52, 53, 54, partitions 55, 56, 57, supporting blocks 58, 59, 60, which are integrally formed on the mounting plate 51 , 66 are integrally formed.
  • the connecting conductors 65, 66 carry contacts 67, 68, while the connecting conductor 64 serves as a bearing for the contact arm 69, which is biased in both stop positions by the tension coil spring 72, which is suspended at the screwing point 70 and in a bore 71 and is shown in dashed lines.
  • the contact arm 69 occupies two stable positions with contact on the one contact 67 of the connecting conductor 66 under high pressure; This tilting behavior of the switching device further promotes the function of the bistable magnetic arrangement (FIG. 1), because it additionally relieves it of the action of force in the end positions.
  • the contact arm 69 is inserted into a recess 73 of the arm 74 so that it is deflected from one position to the other by its movement.
  • the frame 6 from FIG. 1 is made of non-magnetic material with the end walls 101, 102, the spacers 103, 104, the slide rails or runners 105, 106, the integrally molded guide tongue 107, the stop lug 108 and the lug 109 shown alone; the rod-shaped arm 110 can be better seen in FIG. 3b with its slot 111 on one side for receiving the contact arm (69 in FIG. 2); likewise the stop lug 108 and the guide tongue 107.
  • the end wall 103 also contains ventilation bores 114 to 117 for the coil winding (not shown here) (4 in FIG. 1), also one in FIG. 3c by dashed lines Indicated recess 118 for the plate-shaped arm 2b, 119 of the coil body (see. Fig. 1 and Fig. 4) as a guide piece for the frame (6 in Fig. 1).
  • the coil former with side walls 151, 152, permanent-magnetic core 153, which protrudes somewhat beyond the side walls 151, 152, and the plate-shaped arm 154 shown with hollows 155, 156 for the connecting wires of the coil winding; the arm 154 also serves as a guide piece for the frame 6 in FIG. 1, as is partially indicated by dashed lines in FIG. 1.
  • FIG. 5 shows separately how the two-armed lever 201 (25 in FIG. 1) is composed in one piece from the wider arm 202 with the guide lug 203 and the finger-shaped arm 204 with the hemisphere 205 and on one arm 202 of the slide 206 by means of the connecting pieces 207 in one piece.
  • the circuit arrangement of FIG. 6 for generating current pulses of alternating polarity and of selectable duration in accordance with a successive actuation of a button with the input terminals 251, 252 leading to it, the output terminals 254, 255 and leading to the coil winding 253 of the bistable magnetic arrangement according to the invention the power supply lines 256, 257 or rectifier group connected from the series resistor 258, rectifier diode 259, charging capacitor 260, zener diode 261 and the positive "+" DC voltage line 262 for the phase (L) and zero (N) conductors of an AC network
  • Power supply of the JK-FLIP-FLOP module 263 has in the input circuit of the clock input (Cp) 264 the optocoupler 265, by means of which the circuit 266 with the input terminals 251, 252 is galvanically separated from the clock input 264, and in the circuit of the output terminal 254, the antiparallel connected thyristors 267, 268, the "gate" electrodes of which Output
  • the respectively activated light-emitting diode transmits the voltage pulse - electrically isolated - to the associated phototransistor 278, 279, which then controls the relevant thyristor 267, 268 via the associated control electrode so that currents of alternating direction flow through the coil winding; the bistable magnetic arrangement according to the invention is thus caused by currents of alternating direction to change the mutual position of coil 5 and frame 6. Ie. in the case of the embodiment of FIG. 1 that a rapid back and forth movement of the frame 6 is caused and thus actuation of a mechanical or electrical switching device by means of the rod-shaped arm 21. It is readily apparent that instead of an electrical contact group, mechanical elements can also be switched into changing operating positions by the bistable magnetic arrangement according to the invention.
