Definitions

  • the invention relates to an electromagnetic quick release device for electrical switching devices according to the preamble of claim 1.
  • the housing consists of a cup-shaped cylindrical body with an inwardly displaced housing base, which is closed at its two open ends by disk-shaped flanges, one of which flange a lower pole plate Forms ferromagnetic material, which includes an annular permanent magnet between itself and the inwardly displaced housing base, while the end flange at the upper housing end covers a trigger coil which is inserted into the housing from above with a coil-shaped carrier body and with the carrier body on the inwardly displaced housing base sits on.
  • the upper end flange projects with a cylindrical sleeve-shaped body into the interior of the carrier for the trigger coil and also has a cylindrical opening for a tubular actuator for a switch or the like, which consists of ferromagnetic material in its lower part and through the arranged on the housing bottom Permanent magnets against the action of a storage pressure spring, which is arranged in its cylindrical interior and is supported with its lower end against the lower pole plate, is held in contact with the raised housing base.
  • the raised base of the magnet housing serves as a diverter for the magnetic flux, which is generated on the one hand by the permanent magnet and on the other hand by the trigger coil.
  • the entire magnetic flux passes through the part of the diverter with a reduced cross section, further through part of the housing wall coaxially around the permanent magnet and further over the outer one serving as a pole plate Flange back to the permanent magnet.
  • the diverter is saturated and there is no magnetic flux in the rest of the magnetic circuit.
  • the actuating rod which is designed as an impact anchor, moves until it abuts against a projection on the diverter, the storage spring being compressed.
  • the flow of the permanent magnet is hereby divided into two partial flows, one of which runs through the diverter, the housing wall surrounding the permanent magnet and the lower base flange or the pole plate, while the other partial flow through the projection of the diverter, a first axial air gap, the sleeve-shaped Shaft of the impact anchor, a second radial air gap surrounding it, the sleeve surrounding the impact anchor of the second flange, further through the second flange and back over the wall of the housing and serving as the lower pole plate housing flange.
  • the impact anchor is held in the tensioned position of the quick release by the magnetic attraction of the permanent magnet, the magnetic attraction of the permanent magnet being greater than the force of the storage pressure spring inside the sleeve-shaped impact anchor.
  • the magnetic field generated by the coil counteracts the magnetic field of the permanent magnet and reduces the attractive force of the impact armature until the force of the storage pressure spring outweighs the magnetic attraction force and the impact armature is driven up to the triggered position Actuation of a switch or a similar device.
  • this electromagnetic quick release requires a relatively large permanent magnet and has an unfavorable course of the spring characteristic of the accumulator compression spring.
  • the components of this quick release must be inserted individually from different sides into the housing which is open at both ends, which is an obstacle to mechanical assembly and also complicates manual assembly.
  • the invention has for its object to provide an electromagnetic quick release for electrical switching devices according to the preamble of claim 1 so that when the trigger is tensioned on the one hand a favorable course of the spring characteristic and on the other hand a high holding force with a minimal magnet volume.
  • the invention has the advantage that, due to the arrangement of the permanent magnet on the plunger plunger, the magnetic flux in the tensioned state of the quick release forms a closed magnetic circuit, starting from the permanent magnet seated on the plunger plunger, via the magnetic core, the lower pole plate and a lower part of the release coil surrounding the release coil Wall of the housing made of ferromagnetic material of the quick release back to the permanent magnet, which here rests against the upper end of the magnetic core, possibly including a pole plate made of ferromagnetic material.
  • the short-circuit magnetic circuit between the permanent magnet and the upper, narrower part of the wall of the magnet housing results from the displacement of the permanent magnet together with the impact plunger.
  • This behavior of the permanent magnet leads to a favorable course of the spring characteristic of the accumulator pressure spring which loads the anchor plunger in the triggering direction when the trigger is tensioned and also enables a high holding force with a minimal magnet volume of the permanent magnet.
  • the magnetic direction of flux reverses, so that the magnetic attraction forces after the permanent magnet is released from the magnetic core assume the same direction of force as the direction of force of the storage spring. This means that the trigger force of the trigger increases by this force.
  • a particularly simple design of such a quick release results if the anchor plunger has a stop for driving the permanent magnet in the release direction of the anchor plunger, and if the anchor plunger also in the magnetic core protruding from the lower pole plate of the housing against the pressure of the storage pressure spring is guided telescopically coaxially.
  • a storage pressure spring a helical compression spring can advantageously be arranged in the sleeve-shaped magnetic core between the lower pole plate and the lower end of the impact plunger.
  • a particularly small magnet volume of the permanent magnet can be achieved according to a further feature of the invention in that the housing of the quick release above the trigger coil has a cylindrical projection of smaller diameter than the upper part of the wall of the housing, which springs back inwards against the permanent magnet and this or the latter Magnet yoke surrounds part of the height with an annular air gap such that the approach encloses the permanent magnet in the triggered state of the quick release over the entire length or height and the magnetic circuit is short-circuited by the permanent magnet over the wall of the housing approach.
  • a particularly compact design of such an electromagnetic quick release is also achieved in that the housing is provided at the upper end of the anchor plunger with a cylindrical cap of the housing overlapping plastic cap, which is connected to a sliding sleeve, which in turn on the shaft of the anchor plunger against the Pressure of a damper compression spring, which is supported on the permanent magnet or magnetic yoke of the permanent magnet arrangement, can be displaced with limited stops and has an outwardly projecting collar which, in the released position of the quick release, under the action of the damper compression spring on an inwardly directed abutment projection at the upper end of the housing attachment Facility is coming.
  • the plastic cap together with the sliding sleeve against the pressure of the damper spring, can carry out an overstroke up to the stop of the sliding sleeve on the permanent magnet or magnetic yoke, with particularly favorable assembly when assembling such quick releases being achieved in that the sliding sleeve at the shaft end of the impact anchor tappet is secured in a limited manner by means of a clamping ring under the pressure of the damper spring.
  • the electromagnetic quick release 1 consists of a release coil 2, which is surrounded by a housing 3 made of ferromagnetic material.
  • An actuating rod in the form of an impact plunger 6 is arranged inside the sleeve of the magnetic core 4 and is guided in the housing 3 in a slightly movable manner in the axial direction and is under the pretension of a storage pressure spring 7.
  • the plunger plunger 6 itself is made of non-magnetic material, and on the plunger plunger 6 a permanent magnet plate 8 is immovably arranged on a stop 6a, which holds the plunger plunger 6 against the pressure of the storage pressure spring 7 on the sleeve of the magnetic core 4.
  • a ferromagnetic pole plate 9 is provided between the permanent magnet 8 and the sleeve of the magnetic core 4, and for the precise definition of the holding force of the permanent magnet plate 8 on the sleeve there is a thin non-magnetic disk 10, which is made of plastic, between the pole plate 9 and the contact surface of the sleeve. provided as a damping means.
  • a magnetic yoke 11 made of ferromagnetic material is arranged on the side of the permanent magnet plate 8 facing away from the trigger coil 2. This magnetic yoke 11 serves to produce the magnetic circuit of the magnetic field within the magnet housing 3.
  • the end of the anchor plunger 6 protrudes into a plastic cap 12 which consists of a cover cap 13 and an inner sliding sleeve 14 which slides on the shaft of the anchor plunger 6 and is slidably guided in an upper cylindrical projection 15 of the magnet housing 3.
  • the sliding sleeve 14 has a conical collar 16, which is supported on an inwardly projecting conical shoulder 17 of the shoulder 15 of the housing 3 of the quick release 1 and limits the movement of the impact plunger 6 when triggered against the pressure of the storage pressure spring 7.
  • a further damper compression spring 18 is arranged, which, when the quick release is tensioned, that is to say when the permanent magnet 8 is brought into contact with the upper end of the magnet core 4 via the associated pole plate 9, has an overstroke 19 of the tensioning element compensates.
  • the overstroke 19 can extend until the sliding sleeve 14 is seated on the magnetic yoke 11.
  • the permanent magnet 8 is arranged on the plunger plunger 6 above the trigger coil 2 with a narrow air gap 20 relative to the upper part 21 of the wall of the housing 3 in the region of the extension 15 so that in the tensioned state of the quick release 1, the magnetic circuit 22 is closed by the permanent magnet 8 via the magnetic core 4, the lower pole plate 5 and the lower part 3a of the wall of the housing 3 surrounding the release coil 2 (FIG. 1).
  • This magnetic circuit 22 of FIG. 1 is opened when the quick release is triggered. For this, however, a new magnetic circuit 22a (FIGS. 2 and 3) closes from the permanent magnet 8 via the magnetic yoke 11, the housing extension 15 and the pole plate 9. This magnetic circuit 22a acts as a support in the sense of the release movement, while the original one, the storage spring 7 counteracting magnetic circuit 22 (Fig. 1) loses its effect.
  • the hammer plunger 6 moves with the magnet arrangement, which consists of the annular disk-shaped permanent magnet 8, the likewise disk-shaped pole plate 9 and the upper magnet yoke 11, in the intermediate position shown in FIG. 2 after the quick release 1 has been triggered by the magnetic field of the trigger coil 2 in the cylindrical extension 15 of the housing 3 into that the magnetic circuit 22 (Fig. 1) on the lower part 3a of the housing wall, the lower pole plate 5 and the magnetic core 4 is gradually interrupted until it relaxed 3 is only completely short-circuited between the permanent magnet 8 and the narrower part 21 of the wall in the area of the upper housing extension 15 (magnetic circuit 22a).
  • the housing 3 as can be seen in FIGS. 1 to 3 in detail, has the cylindrical extension 15 of smaller diameter above the trigger coil 2, the wall part 21 of which springs back against the permanent magnet 8 and the magnet yoke 11 and 1 surrounds part of the height with a narrow annular air gap 20 in such a way that the magnetic circuit 22 in the tensioned state of the quick release 1 from the permanent magnet 8 with pole plate 9 and magnet yoke 11 via the housing extension 15 and the wall of the housing 3, is further closed via the lower pole plate 5 and the magnetic core 4.
  • the permanent magnet 8 with pole plate 9 and magnet yoke 11 is lifted by the magnetic field of the trigger coil 2 from the magnetic core 4 in the triggering direction 6b and together with the plunger plunger 6 by the storage pressure spring 7 acting thereon and the Approach 15 building closed magnetic circuit 22a in the approach 15 of the housing 3 moves, so that the magnetic circuit 22 via the housing wall 3a, the lower pole plate 5 and the magnetic core 4 is increasingly interrupted until the approach 15 of the housing 3 the permanent magnet 8 in the triggered state of the quick release 1 of FIG. 3 over its entire length or height and thus the magnetic circuit 22a of the permanent magnet 8 is short-circuited via the wall 21 of the housing extension 15.
  • the distance between the cap 13 of the plastic cap 12 and the end face 23 of the housing extension 15 is in the tensioned position of the quick release 1 of Fig. 1 as well as the distance between the sliding sleeve 14 and the magnet yoke 11 so dimensioned that the plastic cap 12 together can perform an overstroke 19 with the sliding sleeve 14 until it rests on the housing extension 15.
