Abstract
Abstract Terminating of an electrical conductor comprising a nonconductive core having conductive means on its surface and enclosed within an insulating jacket is effected by stripping the insulating jacket from at least one end of the conductor and casting an electrically conductive anchor member on the exposed end of the conductor, the anchor member being formed from a molten metal which shrinks upon solidification to provide an exceptionally secure mechanical and electrical bond between the core and the anchor member. The exposed end of the conductor may be kinked prior to the casting of the member.
