As mentioned above, in this invention, two terminal boards are connected by two insulating rods to form an integrated framework, and relay terminals are embedded in the insulating rods, so circuit components can be connected outside the container. Place it within the framework and connect the lead wires of the circuit components to the lead-out terminals of the terminal board,
After shortening and connecting the lead wires using relay terminals, it is possible to fit the terminal board into the container and store the circuit components at the same time. Therefore, assembly work is easy and requires fewer man-hours, and an inexpensive noise filter can be obtained. Further, by extending the internal connection portion of the lead-out terminal on the same line as the relay terminal on the insulating rod, it is suitable for automating the assembly work and the inspection work of the connection point.
