Abstract

1,052,862. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 19, 1963 [May 1, 1963], No. 17229/63. Heading H1K. A semi-conductor rectifier enclosed in a casing with a conductive flange at one end is clamped in thermal contact with a heat sink by means of a mounting structure which engages the flange with a high pressure good electrical contact and provides external connecting means. As shown, the rectifier 1 has a base 2 with a flange 3 forming one contact to which electrical contact is made by an insert 8 which is pressed against the top of the flange 3 by clamping ring 5<SP>1</SP> which is urged towards a copper or aluminium heat sink 4 by three bolts 6. The small area high pressure contact between flange 3 and insert 8 forms an efficient electrical contact while the large area low pressure contact between base 2 and heat sink 4 forms an efficient thermal contact. The conductive insert 8 has a terminal portion 11 which may be connected directly to other components or clamped to heat sink 4. Either the insert 8 or the top of base 2 may be provided with one or more annular ridges to reduce the area and increase the pressure of the electrical contact, and the insert may be omitted, a ridge being provided on the top of the flange 3.
