Abstract: An electronic system which requires high current provides a connector assembly which enables power supplies to be plugged into the same etched backplane as the logic printed circuit boards. The connector assembly handles high current, typically 150 amps at 5V DC. A female connector includes sets of fingers which flex at the base of the fingers to provide a low resistance contact.

Abstract: An electronic system is packaged to provide a single etched backplane. Bus bars are physically fastened to bushings which are soldered to the backplane power etch lines to provide power to the system.Printed circuit boards are plugged into connectors mounted on the backplane for receiving power and transferring logic signals between printed circuit boards. A number of power supplies are plugged into connectors mounted on the bus bars for transmitting power, and plugged into connectors for transferring logic signals.

Abstract: An electronic computer includes a plurality of printed circuit boards that are slideably mounted in spaced parallel planes within a housing. The housing contains an input/output bus arrangement which is substantially open in the middle. A power supply is detachably mounted to the housing in such a manner as to automatically connect to the input/output bus arrangement when it is secured in place. The power supply includes suction fans which draw ambient air in through the front of the housing over the printed circuit boards, through the open portion of the bus arrangement and hence over critical portions of the power supply. The air is initially drawn through perforated openings in a hinged control panel in one preferred embodiment. In another preferred embodiment, the air is drawn through a stationary member at the front of the housing.
