ABSTRACT:
A cable connector includes at least two electrically conductive slip ring members with freely rotatable contact surfaces which are mutually frictionally engaged with one another. Provision is made for selectively forcing the contact surfaces into highly pressurized engagement so as to lock them together during application of current through the cable. The present invention finds particular utility as a rotary joint cable connector for a pneumatically operated spot welding gun.
