Abstract: A signal splitting device is to be installed in a CATV passive apparatus. The signal splitting device includes a circuit board that is disposed in a cover of the CATV passive apparatus, and a first connecting terminal and a second connecting terminal that are mounted to the circuit board and that are connected respectively to input and output terminals of the CATV passive apparatus. Each of the first and second connecting terminals includes a pin electrically connecting the circuit board and the corresponding one of the input and output terminals. The pin has a segment that is between the circuit board and the corresponding one of the input and output terminals and that has a length ranging from 4 to 15 mm.

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.

Abstract: A cable television apparatus is applied to an input coaxial cable and an output coaxial cable to transmit a cable television signal. The cable television apparatus includes an improved choke, an input side, an output side, an input capacitor and an output capacitor. The improved choke is electrically connected to the input coaxial cable, the output coaxial cable, the input side, the output side, the input capacitor and the output capacitor. The improved choke includes a conductive wire and a ferrite core. One side of the conductive wire is electrically connected to the input side and one side of the input capacitor. The other side of the conductive wire is electrically connected to the output side and one side of the output capacitor. The ferrite core covers one part of the conductive wire. Moreover, the ferrite core is a high saturation current ferrite core.
