Abstract
Abstract An electrical connector for interconnecting opposed circuit members (e.g., modules, printed circuit boards) using an interim housing on which are positioned a pair of flexible circuit members which are capable of being expanded to provide desired connections. Expansion is accomplished through the application of pressurized fluid to the housing to cause expansion. Such a fluid (liquid or gas) may also cool the structure during operation. The respective conductors of the expandable flexible circuit members are electrically coupled using a common circuitized element (e.g., a thin dielectric having opposed arrays of conductive members thereon). Means for aligning the connector of the invention with the respective electrical circuit members being connected is also provided.
