Abstract

A printed-circuit card-to-card connector is used at a module site to facilitate alterations of module functions, i.e., patching, addition of functions and increase of I/O pins. the front thereof and printed conductors on either the front or backside for interconnecting modules and for connecting module pins to an off-card connector 20. In many instances, particularly when developing an engineering model or prototype, it is necessary to make circuit changes. It is desirable to have a vehicle for making circuit changes without reworking the entire circuit card. It is difficult to make circuit changes or add function, even if the card is not fully populated, without altering the printed conductor patterns.

Card To Card Connecter

A printed-circuit card-to-card connector is used at a module site to facilitate alterations of module functions, i.e., patching, addition of functions and increase of I/O pins. the front thereof and printed conductors on either the front or backside for interconnecting modules and for connecting module pins to an off- card connector 20. In many instances, particularly when developing an engineering model or prototype, it is necessary to make circuit changes. It is desirable to have a vehicle for making circuit changes without reworking the entire circuit card. It is difficult to make circuit changes or add function, even if the card is not fully populated, without altering the printed conductor patterns. The card-to-card connector obviates any need to alter the printed conductor pattern when making circuit changes or adding function.

The card-to-card connector (Figs. 1, 2, and 3) includes a card stand off connector block 30 having a matrix of pins 31, which have the same center-to- center spacing as module pins and extend thru the block to project outwardly from opposite faces of the block. The pins 31 extending from one face of the block, enter holes 11 at a vacated or removed module site and are secured to the card in the conventional manner. The pins 31 extending from the opposite face of the connector block are received by the female part of bayonet connectors 41 in socket block 40. The male part of connectors 41 enter holes at a module...
