ABSTRACT:
A connector assembly for transferring high-frequency current into or from a Litz-wire electrical cable having multiple conductor strands includes a transition connector component, a terminal connector component, and a coupling collar. The transition component has an annular groove which receives the splayed ends of the multiple conductor strands and makes electrical connection therewith by soldering of the conductor strand ends to the transition component at the groove. The transition component also has a central opening through it for providing flow communication with the internal coolant flow channel of the electrical cable. The terminal connector component has an orifice through it for establishing flow communication between the transition component opening and an external source of coolant. The terminal component also has a tab projecting from it for making an external electrical connection. The transition and terminal components are electrically connected together by fasteners. The collar has a housing of frusto-conical configuration for fitting over end portions of the conductor strands of the cable which have the ends in the annular splayed configuration. An end portion of the housing can be clamped to the Litz-wire cable. The collar housing and transition component have complementary threaded portions for attaching them together.
