Abstract: An electrical terminal member 10 adapted to reduce resistance at a contact interface between two electrical articles comprises first and second connecting portions 12,48 respectively. First portion 12 has an annular section 14 having a fastener receiving aperture 16 extending therethrough, an inner edge 22 adjacent the fastener receiving aperture 16 and an outer edge 28 extending circumferentially around the annular section 14. Annular section 14 further includes a plurality of slots 26 spaced therearound, the slots 26 defining therebetween respective spring sections 32 in an annular array. Each spring section includes respective protrusion 34 extending from a major surface thereof, each protrusion 34 having a crest portion 36. Crest portions 36 are disposed substantially in a common plane and define a contact interface for electrical engagement with a common conductive surface 38 of the first electrical article 60.

Abstract: A connector assembly includes modules which intermate to interconnect electrical circuits between mother and daughter printed circuit boards. The modules are provided with resilient projections which latch on relative rotation of the modules, enabling the handling of resultant modular assemblies. High current carrying terminals of the modules have contact posts of different spacings and lengths from a contact point to assure equal resistivity to avoid hot spots for high current. A polarizing key locking feature is provided by a snap ring including a slot to permit engagement and disengagement by a simple tool such as a screwdriver.
