However, the disturbing voltage induced between the power line 1 and the information line 2 could not be removed. Here, it is not possible to specify what the disturbing voltage induced between the power line 1 and the information line 2 is, but for example, a high-frequency inverter type lighting fixture, a computer display device, a switching device, or the like. Since there are innumerable interfering voltages such as power supply devices, air conditioners and other motors, natural phenomena such as lightning and discharge, and spark noise of automobile engines, these are high frequency between the power line 1 and the information line 2. It is presumed that it is induced as a disturbance voltage of. The power supply line 1 and the information line 2 connected to the device have an antenna action of picking up noise in the space to induce a disturbing voltage, or conversely, radiating the disturbing voltage into the space. However, it has been unavoidable that such an interfering voltage is mixed into the wiring of the signal processing circuit 20. As described above, in the conventional example, there is no defense against the adverse effect that the disturbing voltage induced between the power line 1 and the information line 2 has on the device. There has been a problem that disorder and malfunction of information-related equipment occur.

れている。[Embodiment] FIG. 1 is a schematic configuration diagram of an embodiment of the present invention. The composite outlet 8 has both a power line terminal 11 and an information line terminal 21. The power line 1 is connected to the power line terminal 11, and the information line 2 is connected to the information line terminal 21. An interference voltage bypass circuit 5 is interposed between the power supply line 1 and the information line 2. Further, the disturbing voltage blocking circuit 3 is inserted between the power line 10 and the power line terminal 11, and the disturbing voltage blocking circuit 4 is inserted between the information line 2 and the information line terminal 21. The disturbance voltage bypass circuit 5 is composed of a capacitor or the like that exhibits a low impedance with respect to a high-frequency disturbance voltage. Therefore, the current due to the high frequency interference voltage induced between the power supply line 1 and the information line 2 flows only through the interference voltage bypass circuit 5, and the power supply line 1 and the information line 2
The interfering voltage is not radiated into the space due to the antenna action, and the disadvantage that the interfering voltage in the space is mixed into the wiring of the signal processing circuit 20 can be prevented. Further, the disturbing voltage blocking circuits 3 and 4 are constituted by a filter circuit exhibiting a high impedance against the disturbing voltage, and are made compact and lightweight by using a magnetic material having a high magnetic permeability such as a ferrite core.

In this case, the interference voltage induced between the power supply line 1 and the information line 2 can be prevented from being mixed into the receiving circuit of the television, and the inconvenience such as the disturbance of the received image can be eliminated. Further, it goes without saying that the present invention can be generally used for connection of all devices having two lines of a power line and an information line.
