Ducts are normally used to supply power to equipment in factories, but with the development of multiplex transmission technology and the introduction of FA, it would be convenient if control signals for the equipment could be transmitted through ducts. However, the noise environment in the factory where the duct is installed is very bad, and due to the noise, two duct conductors 2, which are laid in parallel inside the duct frame 1 as shown in FIG. 2' and each of the above duct conductors 2,
The situation was such that accurate signal transmission could not be carried out in a duct incorporating device connecting conductors 3, 3' installed so as to slide with 2'.

の効果により、耐ノイズ性が向上する。 FIG. 2 is a diagram showing a communication duct according to an embodiment of the present invention, which includes a duct frame 1 having a notch in the length direction, and a length of the duct frame 1 inside the duct frame 1. Duct conductors 4, 4' separated in the direction and laid in two rows, and the duct frame 1
along the duct conductor 4,
4' and twisted pair wires 5, 5' connected to the terminal 4'. In the communication duct having the above configuration, signals pass through the twisted pair wires 5, 5' and the duct conductors 4, 4', and the signals pass through the twisted pair wires 5, 5' and the duct conductors 4, 4'.
The signal is transmitted to each device via a device connection conductor (same as 3, 3' in the previous embodiment, not shown) that slides on 4'. In this case, signals of the same polarity are
It is necessary to line up in a straight line. Therefore, signals to be transmitted, such as control signals, are transmitted through the twisted pair of wires 5, 5', and the effect of twisting improves noise resistance.
