PURPOSE: To suppress electric interference from a node of an electric circuit by using a resonance transmission line of interference frequency to be suppressed which is connected to the node of the electric circuit. CONSTITUTION: Bus bars 16 to 19 are fixed at specific positions with an insulating bracket member 20 and electrically insulated. Stub members 22, 24, and 26 are fitted between the bus bars 16 to 19 by the open resonance transmission line. The resonance frequencies of those stubs 22, 24, and 26 give null effect to the bus bars 16 to 19 so as to suppress electric interference between frequencies. The stub 22 is coupled with a bracket member 30, which enables the open transmission line of the stub 22 and bus bars 16 and 17 to be connected. Similarly, the stub 24 is connected between the bus bars 17 and 18 by a bracket member 32 and a bracket member 34 connects the stub 26 between the bus bars 18 and 19. Then an edge assembly 15 couples the bus bars 16 to 19 and circuit modules 11 to 13. |
