Abstract
A cable which provides suitable shielding over a relatively wide range of frequencies includes a core (22), and inner shield (32), an outer shield (34) which engages electrically the inner shield, and a jacket (60). Each shield is a laminate which includes a metallic layer comprising a suitable metallic shielding material and a plastic layer. The inner shield has its plastic layer (38) disposed toward the core whereas the plastic layer (52) of the outer shield is oriented toward the jacket. Also, each shield is formed with an unjoined, longitudinal overlapped seam. In order to insure continued shielding when the cable is flexed, the longitudinal seams of the cable are displaced from each other as measured in a direction circumferentially of the core.
