Abstract

Electrical conductors operating in cryogenic environments can require demountable connections along their lengths. Such connections must have low resistance and high reliability and should allow ready assembly and disassembly. The pelformance of two types of connections has been evaluated. The first connection type is a clamped surface-to-surface joint. The second is a screwed joint that incorporates male and female machine-thread components. The connections for copper conductors have been evaluated expeIimentally at 77 K. Experimental vaIiables included thread surface treatment and assembly methods. The results of the evaluations are presented.
