Abstract

A system for interconnecting orthogonally disposed printed circuit boards in first and second stacks comprises first contact members on facing edges of the boards of the two stacks used to interconnect the boards. A mother board is disposed perpendicular to and between the two stacks of boards. Second contact members are disposed on the same facing edges of the boards as the first contact members. They define with the first contact members a series of first multiway plug-in connectors along the respective edge of each board in the first stack and a series of second multiway plug-in connectors along the respective edge of each board in the second stack. The mother board comprises a distribution network in the form of an array of conductive tracks assigned to distributing signals to the boards. The mother board also carries connecting contact members and distribution contact members connected to the distribution network. They are disposed transversely to the mother board and define on one side of it a set of third multiway plug-in connectors adapted to have the first connectors plugged into them. On the other side of the mother board they define a set of fourth multiway plug-in connectors adapted to have the second connectors plugged into them. These interconnect the first contact members of corresponding first and second connectors via the connecting contact members. They also connect the second contact members of each board to the distribution network via the distribution contact members.
