Embodiment Construction

[0047] figure 1 , Figure 7 , Figure 9 , Figure 11 and Figure 13 An embodiment of the planar transformer 1 according to the invention is shown in each case in longitudinal section. for this in figure 2 , Figure 8 , Figure 10 and Figure 12 , the cross-sections of planar transformers 1 according to the present invention are shown, respectively. The basic structure of the planar transformer 1 according to the invention is described below, which is the same in each embodiment, where only the essential components of the invention and their functions are described.

[0048] The planar transformer 1 comprises a printed circuit board 2 with a rectangular milled-out opening 2a. The printed circuit board 2 is made of copper sheet with a galvanized surface and serves to support the further components of the planar transformer 1 . Furthermore, the planar transformer 1 comprises four windings arranged one above the other in the form of conductor tracks 3 a to 3 d. A magne...

Abstract

A planar transformer includes a printed circuit board, at least two conductor tracks, a base plate, and a recess that is formed in the base plate. A shroud that is formed from an at least partially electrically conductive material is arranged in the recess. The shroud is electrically connected to the printed circuit board.

Description

technical field [0001] The invention relates to a planar transformer having at least a printed circuit board, at least two conductor tracks, a base plate and a receptacle formed in the base plate. Furthermore, the invention relates to an electrical component with at least one planar transformer. Background technique [0002] Planar transformers are known from the prior art, which are implemented in the form of electrical components, in particular in the form of circuits printed on printed circuit boards. Planar transformers of this type often have return space under the printed circuit board. For this purpose, the printed circuit board has a continuous rectangular opening with a surrounding contact area. A base plate made of sheet metal can be arranged below the printed circuit board, said substrate being electrically connected to the printed circuit board in a planar manner. The base plate has a square receptacle which forms and limits a reflow space. High-frequency mag...
