Abstract A clamping device is disclosed for a thermally and electrically pressure-contacted semiconductor component in disk-cell construction which includes two pressure or conductor plates between which the semiconductor component is disposed. The two pressure or conductor plates are squeezed together by a clamping device which includes bolts and flat springs with an adjustable force measurable on the clamping device. The clamping bolts pass through a flat spring and the middle of the spring engages the center of a convex surface on one of the two pressure or conductor plates. A large-area clamping plate with a central threaded insert serves as the flat spring over at least the one pressure or conductor plate. The large-area clamping plate is capable of being stressed over a certain rotation angle proportioned to the force of a central clamping screw which presses on the convex surface. The large-area clamping plate is held by four clamping bolts which pass through the corners of the large-area clamping plate.
A clamping device for a thermally and electrically pressure-contacted semiconductor component in diskcell construction comprising two pressure or conductor plates in the form of liquid-cooled capsules between which the semiconductor component is disposed, the two liquid-cooled capsules being squeezed together by a clamping device comprising four clamping bolts passing through the corners of a large-area resilient clamping plate with a central threaded insert and a central clamping screw pressing on a convex surface of one of the two liquid-cooled capsules, the clamping screw being screwed over a certain rotation angle measurable on the clamping device, stressing the clamping plate and pressing on the convex surface with a force proportional to said angle.
