Definitions

  • the invention relates to a high-frequency transformer according to the first part of patent claim 1.
  • the invention has for its object to provide a high-frequency transformer according to the first part of claim 1, which completely avoids the aforementioned disadvantages and can be automatically wound and further processed.
  • the high frequency transformer according to the invention can be produced in two versions, e.g. as a conventional component with connecting pins or as an SMD component with soldering pads for surface mounting.
  • Fig. 1 shows an example of a first embodiment of the high-frequency transformer according to the invention in three mutually perpendicular views a), b), and c).
  • 1 is the magnetically conductive two-hole core, which is preferably produced by the known injection molding method.
  • This core has warts 3 for defined orientation and fixation of the winding wires 2 at the edges of the holes.
  • the configuration of the core is designed so that a flange 4 allows snap-in attachment in the coil base 5.
  • the sector-like holes facilitate automatic winding.
  • the core also has a pin 7.
  • the coil base can be used both for conventional pinning and when used as an SMD component.
  • the foundation 6 it has square projections 8.
  • Fig. 2 shows another example of the high-frequency transformer according to the invention in SMD (surface mounted device) design.
  • the winding wire in the version according to Fig. 2 is automatically placed several times around the square projections 8, which are also suitable for pinning, and thus prepares the soldering points for SMD soldering. So that the winding wire cannot slip off, each of these projections 8 has a flange 9.

Claims (4)

1. Transformateur à haute fréquence pour des fréquences de 5-1750 MHz, agencé à la manière de transformateurs différentiels comportant des noyaux (1) à deux trous et un enroulement (2) réparti de façon correspondante, caractérisé par l'utilisation d'un noyau magnéti- quement conducteur (1), réalisé de préférence en ferrite, fabriqué de préférence au moyen d'une technique de moulage par injection et comportant, sur ses faces frontales, des boutons (3) permettant le guidage et la fixation du fil et une bride de base (4) permettant la fixation par encliquetage dans un socle (5) de bobine.
2. Transformateur à haute fréquence suivant la revendication 1, caractérisé par le fait que le socle (5) de la bobine est agencé de telle sorte que dans des perçages préparés, ménagés dans des parties saillantes (8), peuvent être insérées des broches (6), auxquelles les extrémités des fils (2) de l'enroulement sont fixées d'une manière conductrice de manière à obtenir un composant d'un type classique.
3. Transformateur à haute fréquence suivant la revendication 1, caractérisé par le fait que respectivement une extrémité du fil (2) de l'enroulement est enroulé autour de parties saillantes (8) du socle de bobine de manière à former un composant SMD.
4. Transformateur à haute fréquence selon la revendication 3, caractérisé par le fait que les parties saillantes (8) situées sur le socle (5) de la bobine possèdent une bride (9) agencée de manière à empêcher une chute du fil enroulé (2).
