An insulated conductor pair and a guide cable using the same

摘要

To provide a layered insulated conductor pair which can be easily manufactured in inexpensive facilities and with which a highly precise and stable degree of electromagnetic coupling can be obtained, and a guide cable using such a layered insulated conductor pair. A layered insulated conductor pair 10A includes a plurality of film-shaped insulators 13, 13' placed one over another, and each insulator has line conductors 11, 11' of specified shape fixed to its front surface or its inside. A layered insulated conductor pair 10B includes a film-shaped insulator having line conductors 11, 11' of specified shape fixed to its front surface or its inside. A layered insulated conductor pair 10C includes electromagnetic screening layers 20 arranged at intervals in close contact with the conductors 11, 11'. A guide cable includes one or more layered insulated conductor pairs 10A to 10C which are formed into a single piece and are surrounded by an outer coating 18. <IMAGE>
