Abstract: The problem of compensating for dimensional differences occurring in the length of adjacent stacks of semiconductors or other electronic components in an electrical assembly of such components is avoided through the use of a plurality of housing sections (12, 14, 16), one for each stack with each housing section being comprised of stacked thin sheets (20) of electrically conductive or electrically insulating material. Some of the sheets have cutouts (42, 142) to receive semiconductors (120, 150). The stacks are tied together by ribbon-like flexible tabs (18) integral with at least some of the sheets (20) and interconnecting the housing sections (12, 14, and 16). The tabs (18) are constructed to be deformable generally independently of the other of the tabs.

Abstract: To provide for electrical connection of electrical components (14), (16) through a rotating shaft (12) in a manner facilitating assembly and disassembly of the connection for replacement of the components (14), (16), a connector assembly (20) is provided. The connector assembly (20) includes an inset (24) disposed within an insulator (22) both of which are fixed within the rotating shaft (12) in proximity to an opening (18) therein, electrical terminals or contacts (26), (28) associated with each of the electrical components (14), (16) in spaced relation thereto, and a conductive bushing (30) extending through the opening (18) in the rotating shaft (12) in electrically isolated relation thereto. Additionally, the connector assembly (20) includes an externally threaded fastener (32) for releaseably securing the electrical terminals or contacts (26), (28) and the conductive bushing (30) to the insert (24) in the insulator (22) to electrically interconnect the electrical components (14), (16) in a manner accessible externally of the rotating shaft (12).

Abstract: On résout le problème qui consiste à compenser les différences dimensionnelles entre la longueur de piles adjacentes de semiconducteurs ou d'autres composants électroniques dans un ensemble électrique de ces composants en utilisant une pluralité de sections de boîtier (12, 14, 16), une pour chaque pile, chaque section de boîtier comprenant de minces feuilles (20) empilées de matériau électriquement conducteur ou électriquement isolant. Certaines feuilles ont des ouvertures (42, 142) pour recevoir des semiconducteurs (120, 150). Les piles sont reliées ensemble par des languettes flexibles (18) allongées, intégralement construites avec au moins certaines feuilles (20) de façon à interconnecter les sections de boîtier (12, 14 et 16). Les languettes (18) sont construites pour être déformables, en général indépendamment des autres languettes.
