Abstract:
The invention relates to an assembly comprised of a panel-like constructed electrical/electronic module (7) comprising a flat surface with exposed, contactable connection sections AS serving as a part of an essentially flat conductor track structure for electrically connecting the module (7). The assembly also comprises a connection unit (1) provided with electrical/electronic elements D, which are located on a conductor track structure (2) situated in a plane parallel to the conductor track structure of the module (7). In addition, the assembly is fitted with means for contacting connection sections of the module whereby enabling the module to be electrically connected via the connection unit. The means for contacting the connection sections AS of the module (7) are bent out from the plane of the conductor track structure (2), and are connection sections AA that represent a portion of the conductor track structure. The connection sections AS of the module (7) are rigid and are electrical conductor sections AS that can be bent out from the plane of the conductor track structure of the module (7). Connection sections AA of the connection unit (1) are arranged according to the arrangement of connection sections AS of the module (7) so that when the connection unit (1) is connected to the module (7), one connection segment AS of the module (7) and one of the connection unit (1) are electrically connected to one another, abut against one section, and, in the area in which they abut, are situated in a spatial position different from that of the planes of the conductor track structures (2).

Abstract:
The present invention relates to a power unit comprising at least one power electronics module (106), a circuit carrier (102), which is connected to said power electronics module, and at least one heat sink (114), which is connected to said power electronics module, in order to dissipate heat. The invention also relates to an associated heat sink and a corresponding assembly method. In order to provide a power unit (100) and an associated assembly method which allows improved dissipation of air heat, as well as adequate electrical insulation of the power modules and simplified implementation, the circuit carrier (102) comprises at least one through hole (108). At least one contact extension (118), which is at least partially received by the through hole (108), is moulded onto the heat sink (114), and the contact extension (118) of the heat sink (114) is thermally contacted with the power electronics module (106) by means of a heat-conductive material.
