Electromagnetic shielding performance evaluation jig and electromagnetic shielding performance evaluation device using the same

摘要

PROBLEM TO BE SOLVED: To improve accuracy in the evaluation and measurement of electromagnetic wave shield performance of an electromagnetic wave shield material to be used wound on a cable.;SOLUTION: The electromagnetic wave shield performance evaluation tool 300 includes a measured cable 340, connectors 350A, 350B which support the measured cable 340 and are connected to both ends of the measured cable, and a terminal resistor connected to one of the connectors. The measured cable has an inner conductor 341, an inductor 342 composed of an insulator covering the inner conductor, an external conductor 343 covering both ends of the inductor, and a protective coating 344 composed of an insulator covering part of the external conductor, an electromagnetic wave shield material and the external conductor coming into contact with each other when the electromagnetic wave shield material is wound around the measured cable.;COPYRIGHT: (C)2014,JPO&INPIT
