Patent number: 7968988Abstract: The power semiconductor module (1) has a heat-conducting base plate (11) on which at least three substrates (2, 3, 4, 5, 6, 7) are placed, each substrate supporting at least one power semiconductor component (8, 9) that gives off heat generated during operation. In order to optimize a power semiconductor module of this type with regard to mechanical load and heat dissipation, the substrates (2, 3, 4, 5, 6, 7) are placed on the base plate (11) while being arranged in a single row (12), and pressing devices (15, 16), which are situated close to the substrate, are provided on both longitudinal sides (11a, 11b) of the base plate (11) while being arranged parallel to the row (12).

Patent number: 4932891Abstract: A dual flat-spring electrical contact includes a contact receptacle which contains a separation gap and on which spring prongs protrude on one side while the cable connector protrudes on the other side. The contact receptacle is rigidly locked against expansion, as in the area of the separating gap, during insertion of a contact pin between the prongs because on a receptacle wall, in the area of the separating gap, there protrudes a T-shaped cover plate for which there is provided a holding recess which adjoins an adjacent contact receptacle wall.Type: GrantFiled: August 22, 1989Date of Patent: June 12, 1990Assignee: C.
