Abstract

An alternative approach to the card on board packaging technology directly powers the card assemblies rather than their being powered from the board, thus eliminating power planes on the planar board. Referring to the drawing, connectors 11 with feed-through pins 13 allow individual or group power supply assemblies 15 to plug directly to card assemblies via feed-through pins. The upper portion of the connectors 11 on the planar boards 17 still remain free for possible engineering change activity. Power supplies for the individual cards can be packaged in cassettes 19, as shown in the drawing, or individual power supply housing assemblies, and the mechanical package 15 may be self-contained and handled as a separate unit.

Rotatable Power Assembly (Self-Contained Unit)

An alternative approach to the card on board packaging technology directly powers the card assemblies rather than their being powered from the board, thus eliminating power planes on the planar board. Referring to the drawing, connectors 11 with feed-through pins 13 allow individual or group power supply assemblies 15 to plug directly to card assemblies via feed-through pins. The upper portion of the connectors 11 on the planar boards 17 still remain free for possible engineering change activity. Power supplies for the individual cards can be packaged in cassettes 19, as shown in the drawing, or individual power supply housing assemblies, and the mechanical package 15 may be self- contained and handled as a separate unit. The individual power supply housing assemblies are maintained in position by upper support rods 21 with alignment rails 22, and may be individually and selectively ejected by ejector rod 23, as shown in the drawing. A DC bus 25 from the power distribution assembly may be used to supply the required voltage to each connector, while power supplies to card assemblies could be individual units or group assemblies of such units. The power supply assembly includes a conventional lock mechanism 27 and a power sensor switch 29. Power is applied to connectors 11 through power receptacle connectors 31. This approach eliminates the need for additional connectors as well as cables and power planes on planar boa...
