Abstract
An improved multiple circuit module for use in an electronic device includes a number of cold plates sandwiched between pairs of circuit boards for taking away excess heat from the circuit boards. Each plate is provided with open spaces which permit communication between the circuit boards, and with circuit boards on other cold plates. Electrical communication between the circuit boards is effected by an array of metallic pins. The pins are received in a perforate pin header which extends along the depth of the cold plate, and pins communicating with other circuit boards extend into a connector block which is placed between a pair of pin headers. Shielding is provided in both the connector blocks and pin headers to prevent electronic cross-talk between pins disposed therein. In one embodiment, a novel type of pin which reduces installation and disconnection friction is utilized.
