Definitions

  • the invention relates to an inductive miniature component, in particular an antenna, formed with a flat, rectangular or polygonal component winding body on which three coil windings are applied such that the axes of these coil windings in the three mutually perpendicular spatial directions (X, Y , Z), wherein a first and a second coil winding are wound in two lying perpendicular to each other in the median plane of the bobbin directions of the width and the length of the bobbin around this and the third coil winding along the narrow side of the bobbin its circumference following this wrapped around wherein the winding body is at least partially made of Ferntmaterial and having on an underside guide elements for guiding the third coil winding on one of its sides.
  • Such components are known in principle (see JP 2003 0925 09 A). They can be used, for example, as antennas in a keyless entry system for motor vehicles or even in radio-transmitting devices using the remote control.
  • the invention has the object of providing an inductive miniature device, in particular an antenna, with the features described above in such a way that a fully automatic, inexpensive production is possible, but in which a secure fit of the third coil winding is guaranteed.
  • a basic idea of the invention is basically to construct the component from two parts, namely once the winding body, which carries all three coil windings and which in a particularly advantageous embodiment can consist entirely of ferrite material, and, on the other hand, a coil plate of electrically non-conductive non-ferromagnetic material ,
  • plastic on which the bobbin is mounted such that the arranged on its underside guide elements engage in correspondingly configured recesses of the coil plate.
  • the coil ends of the first and second coil windings are wound around the guide members on the lower side of the bobbin, and the coil ends of the third coil winding, which is applied only when the bobbin is mounted on the coil plate, are respectively wound around corners or projections of the coil plate .
  • the inner edges of the recesses of the coil plate and adjoining portions at the bottom of the coil plate may have a metallic coating.
  • the corners or protrusions of the coil plate about which the coil ends of the third coil winding are wound and portions adjacent thereto at the bottom of the coil plate may have a metallic coating.
  • connection contacts are provided on the underside of the coil plate, with which the winding ends of the coil windings can be connected by soldering, so that they can be placed directly on a correspondingly equipped circuit board and fastened there.
  • the inductive miniature component according to the invention can be produced quickly and inexpensively on appropriately equipped machines.
  • the inductive miniature component shown in Figs. 1 to 8 has a flat, substantially rectangular component formed winding body 1, on which three coil windings 2X, 2Y and 2Z are applied such that the axes of these coil windings in the three in each case perpendicular to each other oriented spatial directions X, Y and Z have, which are indicated in Fig. 1 and 3.
  • the coil windings are, as can be seen from FIGS.
  • the winding body 1 has on its underside guide elements 1.1 to 1.4 and at its top guide elements 1.5 to 1.8.
  • the winding body 1 and both the guide elements 1.1 to 1.4 at the bottom of the bobbin and the guide elements 1.5 to 1.8 are constructed at the top of the bobbin of ferrite material and are integrally and materially connected to each other.
  • the winding body 1 is placed on a coil plate 3 made of plastic material and connected thereto.
  • the coil plate 3 has over its thickness extending and towards its edge opening recesses 3.1 to 3.4.
  • the inner contour and the arrangement of these recesses corresponds to the outer contour and arrangement of the arranged at the bottom of the winding body 1 guide elements 1.1 to 1.4.
  • This design has the consequence that the winding body 1 can be placed on the coil plate 3 such that the guide elements 1.1 to 1.4 engage in the recesses 3.1 to 3.4 of the coil plate.
  • the winding ends 2.1X of the first coil winding 2X are wound around the guide elements 1.1 and 1.3, while the winding ends 2.1Y of the second coil winding 2Y are wound around the guide elements 1.2 and 1.4.
  • the thickness of the coil plate 3 substantially corresponds to the thickness of the guide elements 1.1 to 1.4 of the underside of the wound body 1.
  • the inner edges of the recesses 3.1 to 3.4 in the coil plate 3 and, as shown in Fig. 5, adjacent to them portions of predetermined width at the bottom the coil plate 3 have a metallic coating.
  • the metallically coated sections at the bottom of the coil plate 3 are labeled 4.1 to 4.4.
  • the winding ends 2.1Z of the third coil winding 2Z are each wound around corner projections 3.5 and 3.6 of the coil plate 3.
  • These corner projections 3.5 and 3.6 of the coil plate 3 and adjoining sections 4.5 and 4.6 at the bottom also have a metallic coating.
  • This design has the consequence that the arranged on the underside of the coil plate 3 sections 4.1 to 4.6 with metallic coating each with one of the coil ends of the coil windings 2X, 2Y and 2Z can be electrically connected by soldering and thus represent the connection contacts for these coil windings.
  • the component can therefore be placed in the assembly with the underside of the coil plate 3 on a correspondingly equipped circuit board and connected to this.
  • the third coil winding 2Z extends on its upper side along the guide elements 1.5 to 1.8 and on its underside on the one hand along the guide elements 1.1 to 1.4 and additionally along the upper surface of the coil plate 3.
  • a secure fit of the third coil winding 2Z is ensured.
  • the guide elements on the winding body 1 are arranged so that they project outwardly and each seen in a circumferential direction of the winding body 1, for example, as in Fig. 7, the guide element 1.5, are arranged at the top of the bobbin 1 substantially in front of a corner of the bobbin 1, while the associated guide elements 1.1 are arranged on the underside of the bobbin, for example, the guide element 1.1, respectively behind the relevant corner.
  • arranged on the upper side of the winding body 1 guide elements 1.5 to 1.8 each have a transversely to their length beyond the adjacent corner led edge, while arranged at the bottom of the bobbin 1 guide elements 1.1 to 1.4 are formed as a hook-shaped, outwardly facing feet.
  • FIGS. 9 to 15 show another embodiment of a winding body, in which although the winding body 11 itself and arranged on its upper guide elements 11.5 to 11.8 made of ferrite material and are integrally connected to each other, the guide elements on the bottom of the bobbin 11, however, not in one piece connected to this. Rather, they are molded from plastic and are attached to the underside of the bobbin 11 and firmly connected with this.
  • these guide elements 6.1 and 6.2 are integrated in pairs in a plastic part 6, which is provided in the mounted state to the inside of the bobbin 11 towards projections 6.3 and 6.4 with pins 7.1 and 7.2, which in corresponding, arranged on the underside of the bobbin 11 holes 5.1 to 5.4 can be inserted.
  • a solid connection is guaranteed here.
  • These guide elements can then be inserted into a coil plate 13, which is shown in FIGS. 16 and 17.
  • the bobbin 13 is provided in the same manner with three coil windings, as explained with reference to FIGS. 1 to 3.
  • the winding ends of the first and second coil windings are in turn wound around the guide elements on the underside of the winding body 11, while the winding ends of the third coil winding are wound around the corner projections 13.5 and 13.6. In the manner already described, these winding ends are then brought into electrical contact with the metalized portions 14.1 to 14.6 located at the bottom of the coil plate 13, and in this way the terminal contacts for the component are formed.
