    Abstract: A cable television system with printed-circuit-board-layout components receives a cable television signal. The cable television system includes a low pass filter apparatus. The low pass filter apparatus includes a printed circuit board, a plurality of low pass filters and at least one grounded metal wall. Each of the low pass filters includes a low-pass-side inductor and a low-pass-side capacitor. At least two of the low-pass-side inductors of the low pass filters are manufactured on the printed circuit board by a printed-circuit-board-layout technology to form at least two low-pass-side printed-circuit-board-layout inductors. The at least one grounded metal wall blocks a magnetic interference between the low-pass-side inductors of the low pass filters. The low pass filter apparatus filters out a signal having a frequency above 1 GHz.

    Abstract: A structure of preventing the release of a network cable plug includes a flexible clip and a positioning cover. The flexible clip includes a plate body, a pair of pins, and a hook plate. The pair of pins is connected against a side of the plug. The hook plate has a latch. The positioning cover includes a bottom cover and a top cover having a through groove. The plug is arranged on the bottom cover. The top cover covers part of the plug and part of the plate body through the plate body and the hook plate disposed through the through groove; the plug is plugged into the plug hole; the latch and the positioning portion are latched to each other. Therefore, the release of the plug can be prevented to ensure the plug to be plugged into the plug hole firmly.

    Abstract: A resistance-type splitting apparatus includes a transformer and a resistor distribution circuit. The resistor distribution circuit is electrically connected to the transformer. The resistor distribution circuit includes a plurality of distribution resistors. The distribution resistors are electrically connected to the transformer. The distribution resistors of the resistor distribution circuit are arranged as a radial pattern. The transformer receives a cable television signal. After the transformer receives the cable television signal, the transformer distributes the cable television signal through the distribution resistors. A transformer turns ratio of the transformer is adjusted to perform an impedance matching with the distribution resistors of the resistor distribution circuit.
