Snap fit support housing for a semiconductor power wafer

摘要

A support housing for a semiconductor wafer which is centered therein between the anode block and the cathode block. It includes two polygonal insulating plates which bear against each of the blocks fitted with notches at 120 DEG to one another in which insulating pins are snap-fitted. In the case of a thyristor, a flexible wire is connected to a contact piece with a spherical end in contact with the trigger of the thyristor by means of a spiral spring. Application to the railway field.
