Abstract

922,010. Electrical wiring arrangements. TEXAS INSTRUMENTS Inc. May 6, 1960 [May 6, 1959], No. 16069/60. Class 37. In an assembly of a stack of circuit modules interconnection between the modules is made by a series of electrically conductive sheets, electrically insulated from each other, each of said conductive sheets having a plurality of openings therein through which the plurality of leads of the circuit modules pass and make contact with selected ones of the conductive sheets. The circuit modules 11, with stiffly protruding leads 12, are stacked one on top of the other, electrical connection to the supply voltage being made by sheets 13 comprising a conductive film 25 laminated to an insulating board 15, Fig. 4b, both being provided with slots 14, Fig. 2b (not shown) and signal path connections being made by sheets 16 comprising an insulating board bearing a printed circuit 18 for interconnecting the slots 17. The terminals 12 are passed through the slots 14, 17 of the stacked conductive sheets and soldered to the appropriate conductors, Fig. 4b. Where a large number of signal leads are used which require the conductive elements 18 to cross over one another, one or more additional insulating sheets 16 are used. Separate stacks of modules may be interconnected using the terminal lugs 27 or alternatively larger sheets may be used. Heat is dissipated from the stacks by stacking copper sheets 19 between the modules 11 or the modules may be placed in slots machined into a heatconducting block Fig. 5 (not shown).
