Definitions

  • the present invention relates to a coil assembly according to the preamble of claim 1, a method of manufacturing and uses of the coil assembly.
  • Hearing devices are, for example, so-called T-coils or telephone coils. These T-coils are considered, for example, in hearing aids as inductors with parasitic effects and installed. This physical coil thus has a quality Q and resonance frequency fres.
  • the DE 198 12 836 is a miniature inductive component for SMD mounting with a one-piece solid core of electrically poorly conductive material, in particular ferrite material, and at least one order The coil winding arranged around the core is described. At least one winding-free portion of the core, at least one of the same material as the core existing connecting pin is integrally formed around which a wire end of a winding with at least one turn is guided around such that a part of the winding at a during assembly of the component of the support surface facing side of the core is located.
  • An object of the present invention is to propose a way in which an additional capacity can be arranged with limited space in small electrical devices.
  • the object is generally to be able to increase the number of components to be arranged internally in the case of small-electrical or electronic devices in electronics with at least one coil, in order to meet corresponding requirements for the electronics.
  • the object is achieved by means of a winding arrangement according to the wording of claim 1.
  • a component or circuit be placed directly on or on the coil at the terminals of the coil in order to connect them together.
  • the coil has solderable, radial terminals, which are at a distance that an arrangement of the component or circuit is possible.
  • connections are arranged on at least one on or on the coil on or resting on the print, such as a plastic plate with two pads on it, on which also the component or circuit, connecting the two terminals to arrange.
  • the component or the SMD is, for example, a capacitor, which is arranged on the front side of a rod-shaped coil and is connected to both terminals, which in turn each with externally supplied terminals, such as strands or wires, are connected.
  • the inventive equipped coil such as a so-called T-coil, not necessarily a cylindrical or rod-shaped coil, but of course the use of annular coils or otherwise suitably designed coils is possible.
  • connection pads so-called connection pads and set there, such as to solder, weld or glue, then to arrange the component or circuit, by means of which the two terminals of the coil are connected together, and finally externally supplied Connect terminals such as strands or wires to the terminals of the coil on the pads.
  • the component such as the capacitor is soldered on both sides at the same time, while the strands or wires are fixed with the terminals individually on the pads.
  • the inventively proposed coil assembly is particularly suitable for use in one
  • FIG. 1 shows in longitudinal plan view schematically a rod-shaped or cylindrical coil, comprising a bobbin 1 and windings mounted thereon 3.
  • the coils proposed according to the invention are usually very small spools in the Size of, for example, a maximum of a few millimeters in length.
  • the two terminals 5 and 7 of the coil On the front side of the cylindrical coil, the two terminals 5 and 7 of the coil, for example, via a capacitor 9 connected to each other. At the same time, the two terminals 5 and 7 are connected to externally supplied terminals 11 and 13.
  • FIG. 2 is the front of the coil out FIG.
  • connection pads 6 and 8 which in turn are applied to a wafer 4.
  • the terminals are soldered on these preferably metal pads, for example. Connecting the two terminals 5 and 7, the capacitor 9 is arranged, and in addition to the connection pads 6 and 8, the external terminals 11 and 13 are performed.
  • annular coil 21 has turns 23 which terminally have the two terminals 25 and 27, which in turn are soldered to preferably metal pads 26 and 28, which pads on a plate 34, for example of a polymeric Material are glued.
  • the terminals 25 and 27 are in turn connected to each other via, for example, a capacitor 29.
  • the coil terminals 25 and 27 are connected to externally supplied lead wires 31 and 33, respectively.
  • connection pads 43 and 45 are arranged on the end face 42 of the coil 1, which may be, for example, a telephone coil or so-called T-coil, to which the terminals of Coil windings are guided.
  • the two connections are connected to one another via a so-called SMD Capacitor (Surface Mounted Device Capacitor) 49.
  • SMD Capacitor Surface Mounted Device Capacitor
  • Leading externally to the two connection pads 43 and 45 are feeding strands or wires 51 and 53.
  • connection pads are used for reasons of space and because of advantageous packaging directly on the coil or T-coil.
  • the T-coil must have the two mentioned, solderable radial connections, which of course have to be large enough and have to be at the correct distance in order to be able to accommodate the (SMD) capacitor.
  • SMD solderable radial connections
  • any other component between the two terminals are arranged, or even an additional circuit.
  • the placement of a component or circuit between the two terminals of a micro-coil is not limited to hearing aids, but miniature coils of the type described can also be used in remote control units, medical devices, etc.
  • such coils can also be used for generating higher frequencies, for signal modulation, for generating smaller inductances in hearing aids, etc.
  • small remote controls for controlling, for example, medical devices, arranged for example in FIG a wristwatch, in a finger ring, etc., to equip with a coil arrangement defined according to the invention.
  • a further advantage of the coil arrangement defined according to the invention lies, for example, in the fact that a plurality of different coils, which have different natural resonances, with suitable capacitances tuned to always identical resonances and used interchangeably on the same circuit.
  • FIGS. 5 to 8 Examples are to be shown in which at least two inductors are arranged on a bobbin. So shows, for example Fig. 5 two coaxially arranged Inductors or coils 1, which are arranged coaxially on a bobbin 2 and which each have two terminals 5 and 7. These connections can, as previously with reference to the FIGS. 1 to 4 represented, each connected via a component, such as a capacitor, with each other. For the sake of simplicity, only a hint of a capacitor 9 is shown, which analogously to the corresponding arrangements in the FIGS. 2 and 3 connected to the terminals of the coils on pads.
  • Analog shows Fig. 6 two inductively arranged inductors or coils 23, which are arranged on an annular bobbin 22. Again, the two coils 23 each have terminals 25 and 27, which again may be interconnected via a component such as a circuit or a capacitor.
  • Fig. 7 shows two inductors or coils 61, which are each arranged on a leg of a U-shaped anchor body 63.
  • the coils 61 each have connections 65 and 67.
  • FIG. 8 shows two coils or inductors 71 arranged concentrically around a bobbin 73, each having terminals 75 and 77. These terminals may in turn also carry a capacitor or an assembly.
  • FIGS. 5 to 8 Based on FIGS. 5 to 8 is to be shown that several inductors or coils according to the invention can be provided with corresponding components or assemblies, of course, the invention not only is limited to two coils or inductors, but also the arrangement of three or more inductances or coils is possible.
