Apparatus for housing circuit cards that comprises a cylindrical housing having an internal wall having a single diameter. First and second cylindrical heat sinks are provided that each comprise a sloped outer surface. The heat sinks are disposed such that the sloped outer surfaces face each other.

Apparatus for housing circuit cards that comprises a cylindrical housing having an internal wall having a single diameter. First and second cylindrical heat sinks are provided that each comprise a sloped outer surface. The heat sinks are disposed such that the sloped outer surfaces face each other. First and second circuit cards are secured to distal edges of respective heat sinks, or pairs of circuit cards are secured to both edges of respective heat sinks. Each circuit card comprises at least one internal interface connector that is designed to mate with an internal interface connector of an adjacent circuit card. A cylindrical card lock is provided that has an outer surface that is designed to contact the internal wall of the housing and an inner surface that has a V-shaped cross section having oppositely sloped surfaces. The respective sloped surfaces of the card lock are designed to mate with the sloped outer surfaces of the respective heat sinks. Apparatus is provided for drawing the heat sinks together to cause the sloped surfaces thereof to press against the respective mating sloped surfaces of the card lock and expand the card lock and secure the card lock, heat sinks, and circuit cards in the housing. First and second sealing plates are optionally provided that seal opposite ends of the housing and provide a hermetic enclosure. External interface connectors are provided on the sealing plates to interface to external electronics and couple signals and power to and from the circuit cards.
