する。 FIG. 1 is a cross-sectional perspective view of a communication duct according to an embodiment of the present invention. The duct body includes a conductor 1 for transmitting signals, a cylindrical ground conductor 2 surrounding the conductor 1 and having an opening in the longitudinal direction, and holding the conductor 1 in the center of the ground conductor 2. It consists of a dielectric material 3 filled inside the ground conductor 2 for electrical insulation, and a cylindrical magnetic material 4 having an opening in the longitudinal direction for magnetic shielding. The shoe that feeds the signal from the duct body and relays it to the electrical equipment includes a contactor 5 for electrically connecting the conductor 1 and the grounding conductor 2, respectively, and a switch for electrically connecting the contactor 5 to the electrical equipment. and a lead member 6 for connection. The shoe slides in the longitudinal direction of the duct while maintaining electrical connection with the conductor 1 and the ground conductor 2 through the contact 5.
かかる構成の通信用ダクトにおいて、伝送すべ
き信号は、導体１、接触子５及びリード部材６を
通して各電気機器へ伝達される。 In the communication duct having such a configuration, signals to be transmitted are transmitted to each electrical device through the conductor 1, the contact 5, and the lead member 6.
従つて、本構成の通信用ダクトは、同軸構造に
なつているうえに、磁性体４により磁気シールド
しているので、電磁ノイズに影響されにくい。 Therefore, since the communication duct of this configuration has a coaxial structure and is magnetically shielded by the magnetic body 4, it is hardly affected by electromagnetic noise.
