PURPOSE:To simplify the structure of a shield box and to easily perform the soldering connection in the wiring method for the power supply connector of a communication equipment. CONSTITUTION:Four through capacitors 20 are directly fixed and installed to a through hole 110 on a back wiring board 11. Grounding patterns are formed on at least one surface around the through hole 110 in the back wiring board 11. An insulated electric wire 23 is soldered and connected to the lead at the side of a terminal 21 of the through capacitor 20. The insulated electric wire 23 is wired to a power supply connector mounting board 13. Thus, the through capacitor 20 is directly connected to the back wiring board 11 to eliminate noise through an grounding pattern 11A of the back wiring board 11, resulting in unnecessitating a shield plate 25 provided between the power supply connector 10 and the back wiring board 11. Thus, the structure of the shield box 105 is simplified and the soldering connection can be easily performed. |
