Abstract

A configuration of an electronics unit is disclosed wherein a plurality of circular circuit cards are arranged in an aligned, parallel relationship. Each card has a central circular inner opening formed therein. A plurality of inner and outer spacer elements support the respective inner and outer peripheries of the cards. The conductive patterns on the cards include a plurality of conductive pads arranged around the inner and outer peripheries of the cards. Circular metal-on-elastomer inner and outer connectors engage respective one of the inner and outer spacers, and the metal traces of the connectors make electrical contact with aligned conductive pads of adjacent cards. The unit includes a cover structure which envelopes the circuit card configuration to form a sealed unit, and an electrically insulating coolant liquid is disposed in the sealed unit in direct contact with the circuit cards and electrical components mounted thereon to absorb heat generated by electrical power dissipation. The electronics unit is particularly well suited to use with a guided vehicle configuration, such as a missile, wherein a tubular center structural member extends forwardly from the aft missile body, and the electronics unit is assembled with the tubular member extending through the central opening in the electronics unit. The sensor platform of the missile receives the tubular support member through a central opening. The sensor platform is secured by a fastener exerting compression forces along the central missile axis, thereby also aligning the sensor platform with the aft missile body containing the missile propulsion system.
