DRY CIRCUIT PHENOMENA AND VARIABLE CONTACT RESISTANCE OF PRESSURE TYPE ELECTRICAL CONNECTIONS

Abstract

The signal levels in modern electronic equipment are often of a very low level and with present trends toward transistorized and miniaturized gear signals of lower levels will be common. Environmental conditions for these equipments are also becoming more severe in shipboard and missile applications. This project concerns the development of methods and instrumentation for a more complete and precise evaluation of pressure type electrical connections in communication circuit sizes. This work resulted in the development of effective methods for detecting: dry circuits at a signal level of 0.1 microvolt or more; contact resistance changes with varying load; and transient and average resistance changes of connections, during mechanical disturbance, of 10 milliohms or more.
