ABSTRACT:
An electrical circuit board interconnection system having motherboard 13 and a plurality of option board assemblies 10. Each option board assembly 10 has circuit board 15 to which is attached male pin connector assembly 12 on one surface and a mating female connector assembly 11 on the other surface. Both connector assemblies are oriented with pins 17 and female receptacles 18 parallel to the surface of the boards 15. Ejector levers 14 attached to female connector 11 to bear against male pin housing 36 to assist in disconnection option boards 10 from each other and motherboard 13. Power transfer bus 42 and signal transfer bus 43 interconnect the male and female pin connection 12 and 11 of each circuit board 15 to facilitate the sequential interconnection of a plurality of option board assemblies 10 to motherboard 13.
