Abstract
A dual resistance connector system is provided to allow the replacement of power regulators in a computer system without removing power from the operating voltage bus. The new power regulator can be 'hot plugged' into the voltage bus without creating a voltage drop on the bus which could lead to voltage transients and logic errors. The low resistance bus bar is augmented by a retractable high resistance contact. The high resistance contact is configured to make electrical connection with the operating voltage bus before the low resistance contact. The establishment of a high resistance circuit allows charging of output filter capacitors without creating a large voltage drop on the operating voltage bus. As installation continues, the low resistance bus bar makes contact and is held in position by a fastener. The fastener is initially held out of electrical contact by a compression spring.
