A high density interconnect system is described which comprises a laminated board including a conductive power plane and a ground plane insulated from each other and containing a series of holes therethrough. Signal contacts, ground contacts, power contacts, data bus interconnect contacts, and feed-through contacts are selectively mounted in the series of holes with the ground contacts and power contacts connected to the respective ground plane and conductive power plane and the other contacts insulated therefrom. Front contact housings are secured against the laminated board means and contain spring-loaded contacts in openings therein for electrical engagement with the signal contacts and for electrical engagement with pins of a signature board. Rear contact housings house contact sections of the signal, power, ground, and data bus interconnect contacts to which input/output connectors of computer boards are connected for supplying power thereto, and operating signals from the computer boards are transmitted via the signal contacts to the signature board which conducts tests on the board under test to test the same. A cam-operative apparatus moves a platen carrying the signature board so that the pins of the signature board are moved into electrical engagement with the spring-loaded contacts.

High density interconnect system

A modular plug board system is disclosed for interconnecting an array of parallel cards in a card cage. The cards are pluggably connected to the IO circuit board of a machine to be programmed by the plug board system. A rear board of the plug board system is divided into sections which impinge one another in side to side relationship. The sections are pluggably connected to corresponding cards and are individually removable from the plug board system to allow for individual removal of the cards from the card cage and from pluggable connection with the IO circuit board. One or more cards may be eliminated from the card cage to allow for discrete wire or cable connection directly from the IO circuit board to an appropriate section of the plug board system.
