  • Flexible coaxial cable and method of making same
    Patent number: 4758685
    Abstract: An improved flexible coaxial cable (24) and method of making same employs an inner conductor (22) having a helically wound dielectric beading (20) wound thereabout in a predetermined pitch dependent on the desired velocity of propogation for the cable (24). A heat shrinkable dielectric tubing (26) surrounds the helically wound beading (20) and locks it to the inner conductor (22) to provide a dielectric core (28) having a constant pitch for the helically wound beading (20) during flexing of the cable (24). A convoluted outer conductor (30, 32, 34, 36) is locked to the tubing (26) of the dielectric core (28) by crimping it to the dielectric core (28) between the helically wound convolutions of the outer conductor (30, 32, 34, 36).
