続構造や回路構成についての改善が報告されているが、
芯線の接続構造については改善がなされていなかった。The high frequency noise from the digital circuit board which causes the image disturbance mainly penetrates into the tuner circuit through the antenna cable which handles weak signals. Conventionally, the low EMI design of the digital circuit board has reduced the radiated electromagnetic field strength and made of metal. A method for reducing high-frequency noise radiated from a digital board that surrounds a digital board with a shield case to an antenna cable has been addressed as a reduction technique. However, the effect depends on the distance between the digital board and the antenna cable, and even if the high frequency noise radiated from the digital board becomes small, if the antenna cable is close to the digital board, the effect of the high frequency plug attached to the antenna cable is reduced. Due to poor contact due to rotation and tilt, it was not possible to prevent the occurrence of image failure due to a decrease in signal level and an increase in noise level. For this reason, it is essential to improve the connection structure between the antenna cable and the tuner, through which an interfering wave enters, and the adoption of the F plug structure and the method disclosed in JP-A-8-78103 or JP-A-10-302905. As in the invention, improvements in the ground (hereinafter referred to as GND) connection structure and circuit configuration have been reported,
No improvements have been made to the core wire connection structure.
