Embodiment Construction

[0053] In the following, refer to figure 1 , figure 2 and image 3 , which respectively show preferred embodiments of the present invention. Figure 1 to Figure 3 are the respective cross-sections of the electrical module 100, Figure 1 to Figure 3 The embodiments differ in the arrangement of the circuit boards and their connections 150 to each other. The electrical modules 100 each have a housing, in which in each case a main circuit board 110 and an additional circuit board 120 are arranged.

[0054] Typically, at least one circuit board PCB1 or printed circuit board of thickness H0 is located in this type of electrical module or electrical device with a narrow housing, which is arranged more or less centrally in the available cavity of the housing , depending on the implementation. Electronic components B1, B2 are mounted on the circuit board PCB1, these electronic components constituting the electronic functions of the module or device. Electronic components are ty...

Abstract

The invention relates to an electric module (100) with a planar transformer. The electric module (100) has a housing (101) with an interior having an internal length (L) and an internal height (PO). The electric module (100) additionally has a main printed circuit board (110) with a first thickness (HO), said main printed circuit board (110) being equipped with at least one electronic component (112). According to the invention, the planar transformer (122) is arranged on an additional printed circuit board (120) with a second thickness (Hl), and the main printed circuit board (110) has a recess (111) which receives the additional printed circuit board (120). Additionally, the main printed circuit board (110) and the additional printed circuit board (120) are connected together via a connection (150).

Description

technical field [0001] The invention relates to an electrical module comprising a planar transformer. Background technique [0002] In particular, planar transformers are used for galvanic isolation of electrical circuits, planar transformers being a special type of transformer characterized by an extremely flat design. Planar transformers can have a design height in the millimeter range and are preferably used in electrical modules or electrical devices which are intended to be particularly compact with respect to their geometrical dimensions. In this case, planar transformers can transfer energy, signals and / or data. The properties of transformers also make it possible to interconnect circuits of different AC voltage levels. [0003] EP 2818031 B1 describes a planar transformer which is designed so as to be extremely flat. This is achieved by arranging the individual windings of a planar transformer side by side in a plane, rather than one above the other as is traditio...
