ABSTRACT:
In a pressure contact housing for semiconductor components, the gate electrode contact ring 4 is provided with spiral recesses 5. The latter can absorb axial movements produced during the assembly of the housing, without loading the material. A good and durable electrical contact between the gate electrode and the gate electrode contact ring is obtained thereby.
