搬送通信回路に悪影響を及ぼす欠点がある。However, the conventional connection outlet 8 has the following problems. Load equipment connected to an outlet directly applies noise and switching surges to the power line during normal operation and when starting and stopping. Noise and switching surges superimposed on the power line cause distortion in the carrier signal output from the carrier communication device connected to the power line, so many load devices are equipped with capacitors to absorb noise and switching surges. Some of the many load devices do not have capacitors. In addition, although the capacitors included in this load equipment are effective in absorbing noise and surges generated by the load equipment, they also absorb power line carrier signals, which has the disadvantage of having a negative impact on the power line carrier communication circuit. .
