Abstract
A rotating power connector for an electric welding torch unicable includes a generally cylindrical outer housing having a longitudinal axis. A connector pin is fixedly, axially disposed within the outer housing and extends from one end thereof. A rotating stud is rotatably, axially disposed within the outer housing and extends from another end thereof. The connector pin and the rotating stud have ends in contact within the outer housing. A secondary electrical contact ring also is disposed within the outer housing. The secondary electrical contact ring includes at least one contact portion contacting the rotating stud. At least one biasing member is disposed between the rotating stud and the contact ring. The biasing member urges the rotating stud into engagement with the connector pin and urges the contact ring into engagement with the rotating stud.
