Computer system with improved power bus

摘要

A multi-layer power bus (18) is described that includes input tabs (24) and three legs (32, 34, and 36) and that connects a matrix of power supplies to a circuit board (12) in a computer system. The power bus (18) is substantially planar and attached to the circuit board (12) so that the power bus (18) and circuit board (12) are parallel to one another. This parallel relationship decreases the amount of space utilized by the circuit board (12) in the computer system. The circuit board (12) also has connectors for delivering power directly to tabs (72, 74) on circuit board (12) which increases the efficiency of power delivery. Each connector (44) includes a U-shaped spring housing (48) located within a hollow shield (52) and is joined to one of the power bus voltage layers by a braided copper cable (46).
