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.
