Description

A two distributor for a enclosure filter}

The present invention relates to a distributor for equally dividing the input RF signal, and more particularly, to divide the RF signal into two so that the subscriber can simultaneously watch TV and the Internet (INTERNET) using the RF signal. The present invention relates to a filter-integrated splitter that does not require a separate filter by incorporating a filter in the distributor that blocks various harmful noise propagated at the side.

In general, the distributor refers to a product that is used between the receiver's home TV terminals in the transmission network and the internal transmission line, equally divides the input RF signal, and is designed to be suitable for transmitting and receiving data with subscribers. It is well known that it is widely used with explosive increase.

Such a distributor will be described below based on the accompanying drawings of the related art.

FIG. 1 is a schematic diagram of a conventional two divider, in which a CATV signal is input to one end thereof, and a TV divider 10 connected to a TV modem 30 and a computer modem 40 at the other end thereof are connected to a TV. 54MHZ ~ 750MHZ high-pass filter (HIGH-PASS FILTER) 20 for blocking harmful radio waves are installed separately.

4 is another installation schematic diagram of a conventional divider, in which a CATV signal is input to one end thereof, and in the divider 10 to which the TV 30 and the computer modem 40 at the output end thereof are connected, 54 MHZ to 216 MHZ band pass filter (BAND-PASS FILT-ER) 60 is installed at the transmission end of the TV 30 side, while the 17 MHZ to 750 MHZ high pass filter (HIG-H PASS FILTER) is installed at the computer modem 40 side. The configuration 70 is provided separately.

7 is another installation schematic diagram of a conventional divider, in which a CATV signal is input to one end thereof, and in a divider 10 to which the TV 30 and the computer modem 40 at the output end thereof are connected. , 54MHZ-750MHZ HIGH-PASS FILTER 90 and 17MHZ-750MHZ HIGH-PASS FILTER (100) to block harmful radio waves which are induced by TV 30 and computer modem 40 Are the installed configurations.

Therefore, the above configuration is such that when the RF signals of various broadcasting channels and Internet data transmitted from Internet service companies and cable broadcasting stations are transmitted to each home through a coaxial cable, which is a transmission line, the distributor installed in the home is a TV (30). Using the viewing and the modem (40) to be able to use the Internet information at the same time.

Here, the high pass filter 20 shown in FIG. 1 is for blocking various harmful waves emitted from the TV from joining the transmission line, and the band pass filter 60 of FIG. 4 passes only the VHF channel frequency band. While the high pass filter 70 is installed to remove noise propagated at the subscriber side during Internet communication, the high pass filter 90 and 100 of FIG. It is installed to subscribers who are watching TV and cable broadcasting. It is installed to block harmful radio waves from each subscriber.

As described above, the conventional splitter has a separate high pass filter and a band pass filter installed separately between each TV and the modem side, thereby incurring a separate purchase cost and cumbersome installation work.

On the other hand, in the case of the first quarter applied to the Internet and cable broadcasting shown in FIG.

Accordingly, the present invention has been made in consideration of various matters as described above, and an object thereof is to divide an RF signal into two so that a subscriber can simultaneously watch TV and the Internet (INTERNET) using an RF signal, By providing each filter (high pass filter and band pass filter) which cuts out various harmful noise propagation into a divider, it provides a built-in filter divider which does not require a separate filter purchase.

<Explanation of symbols for the main parts of the drawings>

10: 2 divider, 20: high pass filter,

30: TV, 40: Modem,

50: SFK2F (filter-integrated splitter).

The present invention for achieving the above object is a CATV signal is input to one end, and in the configuration of the two-distribution means for connecting the TV and the computer modem of the output end of the other end, the signal for bidirectional communication and TV viewing of the modem It is provided with two distribution means to equalize, but it has the characteristic that this two distribution means incorporates the filter means which blocks the joining of the harmful radio wave of a TV or modem side to a transmission line.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a schematic installation diagram of the present invention filter built-in divider, Figure 3 is a detailed circuit diagram of FIG.

CATV signal is input to one end, and in the configuration of a splitter 50 to which the TV 30 and the computer modem 40 of the output end, which are the other end, are connected, to block harmful radio waves which are induced by the TV 30. That is, as shown in FIG. 3, a 54MHZ to 750MHZ high pass filter 51 composed of a resistor, a capacitor, and a coil is installed.

Here, the high pass filter is generally referred to as a high pass filter or a high pass filter, and a circuit which passes a frequency higher than a certain frequency (cutoff frequency) as it is and prevents a lower frequency thereof, and a cutoff frequency applied to the present invention is 54MHZ. It is as follows.

FIG. 5 is a schematic diagram illustrating a two-divider of the present invention with a high pass filter and a built-in band pass filter. FIG. 6 is a detailed circuit diagram of FIG. 5.

CATV signal is input to one end, and in the configuration of the divider 80 to which the TV 30 and the computer modem 40 of the output end, which are the other end, are connected. That is, as shown in FIG. 6, 54MHZ to 216MHZ bandpass filter 82 and 17MHZ to 750MHZ high pass filter 81 each of resistors, capacitors, and coils are installed.

Here, the band pass filter is installed so that only VHF channels can be viewed by subscribers who do not watch pay broadcasting.

FIG. 8 is a schematic view illustrating a two-divider with a high-pass filter built in the present invention, and FIG. 9 is a detailed circuit diagram of FIG.

The CATV signal is input to one end, and in the configuration of the splitter 110 to which the TV 30 and the computer modem 40 of the output end, which are the other end, are connected, to block harmful radio waves which are induced by the TV 30. That is, as shown in FIG. 6, 54MHZ to 750MHZ high pass filter 111 and 17MHZ to 750MHZ high pass filter 112 each including resistors, capacitors, and coils are installed.

The above example is only one embodiment of the present invention, and within the scope of the construction of the present invention, for example, the same as in the case of the first quarter can be changed and modified as much as possible.

Therefore, the above-described configuration is generally used when the RF signals of various broadcast channels and Internet data transmitted from Internet service companies and cable broadcasting stations are transmitted to each home through a coaxial cable, which is a transmission line, and the distributor installed in the home uses the (30) It is possible to simultaneously use the Internet information by using the viewing and modem 40 is the same as the conventional description.

In other words, the high pass filter shown in FIG. 2 is for blocking various harmful waves emitted from the TV from joining the transmission line, and the band pass filter of FIG. 5 passes the VHF channel frequency band to view the VHF channel. On the other hand, the high pass filter is installed to remove noise propagation at the subscriber side during Internet communication, and FIG. 8 is installed at the subscriber having the Internet and cable broadcasting. It is installed to block radio waves.

As described above, the present invention divides the RF signal into two so that the subscriber can simultaneously watch TV and the INTERNET using the RF signal, and blocks each harmful noise wave induced from the subscriber. By installing a pass filter and a band pass filter in a splitter, it is not necessary to purchase a separate filter, so it is economical and convenient to install.
