ABSTRACT:
A pulling assembly for gas cables and a method for manufacturing such an assembly is herein disclosed. A hollow cylindrical shell is provided with a cylindrical opening at one axial end and a reduced diameter threaded axial opening at the other terminal end. A pulling eye is provided having a passageway formed generally coaxially within a shank portion thereof and extending to the body of the eye wherein a transversely disposed threaded opening is formed to communicate with the coaxial passageway. The shank is threaded for mating engagement within complementary threads formed in the second axial end of the shell. Stainless steel tubing, or the like, is soldered within the coaxial passageway of the pulling eye. The cable to which the assembly is to be connected is stripped and the shell is inserted over the conductors with the shell tubing inserted within the central interstice of the cable. The shell is crimped onto the conductors and the stripped portions of the cable repositioned over the shell. Thereafter, the entire assembly is lead soldered so as to hermetically seal the cable.
