Definitions

  • the present invention relates to an electromagnet arrangement with a magnet armature which is immersed in a magnetic field generated by the electromagnet between two pole legs of a U-shaped magnetic core and which is in particular part of a metering device in automatic drinks dispensers for metering beverage concentrates.
  • the object of the invention is now to provide an electromagnet arrangement with U-shaped pole legs for influencing a plunger armature, which is constructed as simply as possible in terms of production technology and also offers the functional requirements of a favorable magnetic flux. In addition to these requirements, there should also be favorable conditions for space-saving installation.
  • An electromagnet arrangement which meets these requirements to a high degree, is characterized according to the invention in that the electromagnet coil is arranged on a cylindrical core made of ferromagnetic conductive material and each end has a flat profile leg made of ferromagnetic conductive material and that the flat profile leg with the cylindrical core are connected mechanically and magnetically conductive.
  • the electromagnet arrangement designed according to the features of the invention fulfills all manufacturing, functional and installation requirements according to the task.
  • the coil carrier body which is wound with insulated wire, can be wound by machine and is then attached to the cylindrical core.
  • the flat-profile legs are then mechanically and magnetically attached to this cylindrical core as pole pieces.
  • This flat design of the legs is also favorable for the magnetic flux in the area of the plunger. This creates a broad, homogeneous magnetic field at this point.
  • the electromagnet arrangement with the flat-profile legs as pole shoes also offers particularly favorable conditions in terms of installation technology.
  • the overall width is relatively narrow and smooth-walled. Nevertheless, the magnetic current, which in particular emerges from the end of the electromagnetic coil, is taken over by the flat-profile legs and directed into the area of the plunger.
  • the electromagnet arrangement according to the invention is characterized in that the cross section of the flat-profile legs tapers towards their free ends. is. This takes into account the fact that the magnetic flux in the legs decreases towards the free ends, specifically because the magnetic field over the magnet armature has a wide area extends between the flat profile legs. In addition to the reduction in weight, this tapering toward the free ends of the flat-profile legs also has a favorable influence on the magnetic field.
  • the electromagnet arrangement according to the invention is characterized in that the coil carrier body has approaches for functional mechanical alignment of the flat-profile legs.
  • the flat-profile legs can be adjusted to each other and to the coil carrier body after being placed on the cylindrical core in corresponding cylindrical bores. This is followed in a simple manner by wedging or riveting the cylindrical core in the cylindrical openings of these flat-profile legs to form a unit.
  • the electromagnets according to the invention can preferably be used particularly advantageously in a housing, in that the end flanges of the magnet coil support body have latching projections which interact with latching projections in the housing.
  • pole legs of the U-shaped magnetic flux body prefferent for the pole legs of the U-shaped magnetic flux body to have support surfaces for bearing on contact surfaces in the housing.
  • the measures taken according to these features further developing the invention are outstandingly suitable for arranging and fastening an electromagnet with a U-shaped magnetic flux body in a housing.
  • the electromagnet is supported in the housing via the pole legs of the U-shaped magnetic flux body, while the latching projections on the magnet coil support body ensure the latching in the housing. So no further fasteners are required.
  • the magnet coil carrier body is usually and expediently made of plastic, the applicable manufacturing expenditure for the fastening measures of the electromagnet in the housing is extremely low.
  • the electromagnet can be fastened in a form-fitting manner in the housing. It is expedient that the locking lugs of the magnet coil support body in Close range of the plane formed by the support surfaces of the magnetic flux body.
  • An electromagnetic coil 2 applied to a coil carrier body 1 is arranged on a cylindrical core 3 made of ferromagnetic material.
  • a cylindrical core 3 made of ferromagnetic material.
  • two flat-profile legs 4 are arranged, which have cylindrical openings in which the cylindrical core 3 is wedged.
  • the free ends of the flat-profile legs protrude into the area of a metering valve for beverage concentrates, such as are used in devices for mixing soft drinks.
  • a part of the control slide 6 of this metering device 5 consists of ferromagnetic conductive material and can thus be influenced as a plunger 7 between the free ends of the flat-profile legs.
  • Lugs 8 on the coil carrier body 1 serve, among other things, to align the flat-profile legs 4 with respect to the coil body 1 and thus also against one another in the preassembly.
  • these approaches 8 also serve as latching elements when installing the electromagnet arrangement in a housing.
  • the flat-profile pole legs 4 rest in the device housing 8 on support ribs 9 and are guided laterally through the housing bulge 10 to the metering device 5.
  • locking projections 11, 12 are arranged in pairs on the end flanges of the magnet coil support body 1.
  • the electromagnet is held against the supporting ribs 9 via locking lugs 13 of the housing with the flat-profile pole legs 4.
  • the locking lugs 12 of the magnet coil support body 1 engage in recesses 14 within the supporting ribs 9.
  • These locking lugs 12 are wedge-shaped, so that the electromagnet on the supporting ribs 9 in its installed position, in which the locking lugs 11 of the magnet coil support body 1 under the locking lugs 13 of the housing come to rest, can be inserted with elastic expansion of the support ribs 9 and is held in a positive manner in this position.
  • the electromagnet arrangement can also be removed from the device housing 8 again.
  • the electromagnet arrangement is additionally secured against lateral displacement via the end flanges of the magnet coil support body 2 between the support webs 9.
