Abstract

The diode consists of a semi-conductor element (4) inside a sealed case. The semiconductor is welded to the shaped metal sole of the case and to a wire (5) thus forming the two connections. The case is part filled with nonconductive resin (11). The side walls of the case are made of a sleeve (1) fixed onto the metal base (3). The base is produced from a metal blank with only two stamping and one cutting operations, the latter to form a lip (10). The sleeve is pressed onto the base and held in place by the rim (8) and the lip of the base. The sleeve is formed in a single operation being pressed into place, shaped and cut off. The rim is formed as a supplementary operation.
