METHOD OF ISOLATING SHIELDING CONDUCTOR SYSTEM FROM LOW FREQUENCY POWER SOURCE AND DEVICE FOR ISOLATING SHIELDING CONDUCTOR SYSTEM

摘要

LINE ISOLATION AND INTERFERENCE SHIELDINGFOR A SHIELDED CONDUCTOR SYSTEMABSTRACT OF THE DISCLOSUREA method and structure is disclosed for isolatingthe shield of a shielded conductor system from a low fre-quency power source to which the shield may be connected.In a preferred embodiment, the isolation technique includesproviding an interruption in the conductor's shield andsituating within the interruption dielectric and mag-netically absorptive material so as to create at leasta pair of capacitances across the interruption, and suchthat the capacitances are separated by magneticallyabsorptive material. In this manner, low-frequency isola-tion is achieved and the field within the cable is shieldedfrom ambient high frequency electromagnetic interferencewhich could otherwise leak through the interruption intoa desired high frequency signal path within the conductor.
