Abstract: A cable television apparatus includes a coupled-line directional coupler. The coupled-line directional coupler includes a coupled-line directional coupler body, an input side, an output side and a coupled side. The coupled-line directional coupler body receives a cable television video-audio-data signal through the input side or the output side. The coupled-line directional coupler body receives a high frequency signal through the input side. A frequency of the high frequency signal is higher than a frequency of the cable television video-audio-data signal. The coupled-line directional coupler body electromagnetically couples the high frequency signal to the coupled side. The coupled-line directional coupler includes a high pass filter function at the coupled side to filter out the cable television video-audio-data signal.

Abstract: An electronic apparatus includes a printed circuit board, a terminal and a surge voltage protection structure. The printed circuit board includes a first plated through hole, a second plated through hole and a ground terminal. The surge voltage protection structure includes the first plated through hole and the second plated through hole. The first plated through hole is electrically connected to the terminal. The second plated through hole is connected to the ground terminal. A gap is defined between the first plated through hole and the second plated through hole. The first plated through hole receives a surge voltage to generate an electric arc across the gap and transmit the electric arc through the gap to the second plated through hole, so that the second plated through hole receives the electric arc to transfer an energy of the electric arc to the ground terminal.
