Definitions

  • the invention relates to an inductive component, in particular an antenna, with a coil body, which is designed as an elongated provided with at least one interior component and is applied to the at least one coil winding, wherein at least one ferromagnetic component is arranged in the interior of the coil body.
  • a ferromagnetic component in which a plurality of substantially tubular ferrite cores arranged along a line perpendicular to their tube axes line and along this line via at least one flexible and within predetermined limits stretchable and elastic, linear support member are interconnected.
  • the carrier element may be formed as a narrow strip of plastic material or silicone rubber, on which the cores are glued.
  • This known component is intended for use as a throttle element for multiple plug-in connections, wherein the electrical conductors of the multi-pin connector are each guided by one of the tubular ferrite cores. For use as an antenna, this known device is not suitable.
  • the invention has the object of providing an inductive component, in particular an antenna, with the features specified in the preamble of claim 1, in such a way that it is flexible and flexible overall and can be adapted to narrow and curved installation spaces.
  • a basic idea of the invention is to produce the bobbin from a flexible material, so that it is designed to be bendable, in particular transversely to its longitudinal axis, and to arrange a plurality of rod-shaped, ferromagnetic components, in particular ferrite cores, parallel to each other and directly adjacent to one another in the interior of the bobbin. that theirs Longitudinal axes lie transversely to the longitudinal axis of the bobbin in a common plane.
  • One or more coil windings are then applied around this flexible and flexible bobbin. In this way, an inductive component which can be used as an antenna is obtained, which is flexible transversely to its longitudinal axis and can thus be adapted to narrow and curved installation spaces.
  • the bobbin may be formed as a hose-like, closed at both ends component. But the bobbin can also be constructed of two attachable parts, which limit the interior in the attached state. In this case, the parting plane of the two parts can be attached to each other parallel to the longitudinal axis of the bobbin. The two parts of the bobbin which can be attached to each other can be designed to be plugged together.
  • the bobbin may consist of a flexible plastic material or silicone material.
  • FIG. 1A and 1B show the construction of a flexible bobbin.
  • a plurality of rod-shaped cylindrical ferrite cores 2.1 to 2.8 are arranged on a length 1 parallel to each other and lying directly next to one another in a plane.
  • the ferrite cores 2.1 to 2.8 are then placed in this position in a bobbin, which is composed of two cap-shaped parts 1.1 and 1.2, which are opposite to each other and can be attached to each other and the interior of the bobbin in which the in FIG. 1B limited by reference numeral 2 ferrite cores are arranged.
  • the parting plane of the two parts 1.1 and 1.2 is parallel to the longitudinal axis L of the bobbin.
  • FIGS. 2 and 3 show the finished inductive component.
  • FIG. 2 contains the coil body consisting of the parts 1.1 and 1.2, the ferrite cores 2 and on its outer side a coil winding 3 with a coil input E and a coil output A is applied. How one FIG. 2 remove can, the usable as an antenna device is transverse to its longitudinal axis bendable.
  • FIG. 3 shows a similar component with a likewise composed of two parts 1.1 'and 1.2' bobbin on the outside of a coil winding 3 'with coil input E and coil output A is applied.
  • the device is how FIG. 3 Removable, repeatedly bendable in different directions transverse to its longitudinal axis.
  • FIGS. 4A to 6 show an antenna which is constructed with tubular ferrite cores.
  • the presentation of the FIGS. 4A to 6 corresponds to the representation of FIGS. 1A to 3 ,
  • the parallel juxtaposed tubular ferrite cores 12.1 to 12.8 are introduced into a bobbin, which is composed of two cap-shaped parts 11.1 and 11.2, in which the ferrite cores 12 are arranged.
  • FIG. 5 shows a first constructed from such ferrite cores 12 antenna with a coil winding 13 having an input E and an output A.
  • FIG. 6 shows an antenna analog to the illustration after FIG. 3 with tubular ferrite cores 12 ', which are introduced into the coil body consisting of the parts 11.1' and 11.2 ', on which a coil winding 13' is applied with input E and output A.
  • FIGS. 7A to 9 show an antenna which is constructed with ferrite cores having a rectangular cross-section.
  • the representation here corresponds to the representation after the FIGS. 1A to 3 ,
  • the ferrite cores 22.1 to 22.5 are in turn arranged parallel to each other along the length 1 and are introduced into a bobbin, which is composed of two attachable cap-shaped parts 21.1 and 21.2, in which the ferrite cores 22 are arranged.
  • FIG. 8 shows an analog FIG. 2 built-up antenna with the bobbin after FIG. 7B and a coil winding 23 with input E and output A.
  • FIG. 9 shows an analog FIG. 3 constructed antenna with a consisting of the parts 21.1 'and 21.2' bobbin in which the ferrite cores 22 'are arranged and on which the coil winding 23' with input E and output A is applied. In all cases it can be seen that the antennas are bendable transversely to their longitudinal axis.
  • the bobbin could also be constructed of two transversely extending to the longitudinal axis of the rod-shaped components, opposite receiving rails, which together form the bobbin, but not directly adjacent to each other and in each of which the ends of the rod-shaped components are inserted and around them the winding is applied.
  • the bobbin could also be constructed of two transversely to the longitudinal axis of the rod-shaped components extending, opposite one another and two-dimensionally applicable foil sections made of flexible material.
  • a plurality of recesses are embossed, in each of which at least one rod-shaped ferrite core can be inserted transversely to the longitudinal axis of the film section such that the ferrite cores are arranged parallel to each other and immediately adjacent to each other and their longitudinal axes transverse to the longitudinal axis of the film section and in a common Lie flat.
  • a second film section is placed on the first film section and connected thereto. The result is an inductive component having a plurality of interiors, in which the ferrite cores are introduced, and which also results in the application of a coil winding a transversely to its longitudinal axis flexible antenna.
