EXPLORATORY ENVIRONMENTAL EVALUATION OF SOLDERLESS WRAPPED CONNECTIONS
Abstract
The solderless wrapped connection (or wire wrap connection) is finding extensive use in both commercial and military electrical and electronic equipments. Wire wrapping is a technique for electrically and mechanically connecting a solid conductor to a terminal by wrapping a specified number of turns of wire, under tension, around a terminal having two or more sharp edges. The increasing use of the solderless wrapped connection as a wiring technique is accompained by an increasing need for a comprehensive evaluation of the wrapped connection to determine its performance capabilities under a wide spectrum of environmental states, including those encountered under both ground and aerospace conditions. As a step infulfilling this need an exploratory environmental evaluation program was conducted to establish environmental capabilities of wire wrap connections with respect to temperature, vibration and salt spray exposures, and to provide designers and users with some guidelines for wire wrap application in military systems. Although basic test procedures and environmental limits were developed around existing military specifications, the severity of these tests, both in duration and environmental extremes, was extended well beyond the requirements of these specifications. This was done in an effort to explore wire wrap characteristics under conditions far more extreme than those presently specified for wrapped connections and to possibly establish ultimate capabilities.
