  • Layout of power semiconductor contacts on a cooling surface
    Patent number: 7845994
    Abstract: An arrangement for contact-connecting at least one electronic component mounted in a housing with connection wires to a cooling surface and a spring element that can be fixed in the housing and has at least one spring arm which presses the component against the cooling surface in a contact-pressure position of the spring element is presented. The arrangement is characterized in that the spring element can be inserted into the housing without touching the component, and the housing is provided with retaining means for the spring element adapted in a manner so that no shear forces are produced in the longitudinal direction of the connection wires when the spring element is mounted.
