Abstract
A coaxial cable has a plurality of insulated beads threaded onto an inner conductor and individually having an exterior shape such that a gap exits between each adjacent pair of beads with the gap increasing in width radially. A conductive flexible braid ensleeves the beads with that braid having interstices ventive of air but preclusive of the passage of plasma. An insulative covering ensleeves the braid and also is ventive of air but preclusive of passage of the plasma. A connector includes a termination having a barrel-shaped body fitting over the outer cable conductor. An outer connector element projects outward from the outer end of the body with that element having longitudinal slots that define a circumferentially-spaced series of flexible fingers. Those slots are ventive of air but have a size sufficiently small to preclude passage of a plasma. An inner electrical connector element projects outwardly from the inner cable conductor beyond the body. Finally, a mating connector fitting defines interchangeable connective elements. An overhang shadow-shields otherwise exposed slots.
