Description

Wall jack for telecommunication for transmitting voice analog signal / digital data signal

The present invention relates to a composite signal processing wall jack for transmitting voice analog signals / digital data signals, and more specifically, to separate voice analog signals / digital data signals transmitted through one LAN cable and to existing MFC telephone terminals and personal computers. A composite signal processing wall jack for each transmission to a computer's LAN card.

Currently, most offices, homes, and the like perform digital data communication and external Internet access inside the office through a LAN line, and perform voice analog data communication inside and outside the office through a separate general telephone line. As digital data communication becomes more common, LAN cables (unshielded twisted pairs, also known as UTP lines) are laid throughout the building when new buildings and apartments are constructed, and RJ-45 wall jacks (also commonly referred to as keystone jacks). In general, it is common to construct a separate LAN cable for digital data communication in an older building that does not have a LAN cable in advance. Also, in some cases, do not wire telephone lines separately in the building, use up to four telephone line lines using LAN lines (8 contacts / 8 strands) instead of telephone lines, or change the RJ-45 jack to RJ-11 jack, In some cases, only two of the eight LAN lines are used to connect ordinary MFC phones.

Thus, conventionally, both telephone wires for voice analog signal transmission and LAN wire wires for digital data signal transmission are installed, and a wall jack for connecting these wired telephone wires and LAN wires to telephones and computers is provided in each room or office. At least one is installed on. Such a conventional wall jack includes two connection blocks (for example, 110D connector blocks) connected to telephone lines and LAN lines wired inside a building, and connector jacks corresponding to the two connection blocks (for example, RJ-11). Jacks and RJ-45 jacks).

However, by wiring the telephone line for voice analog signal transmission and the LAN line for digital data signal transmission separately and connecting them to each connection block, the wiring cost and installation cost of the wall jack are increased. In addition to the complicated wiring, the number of jacks is limited due to cost.

Therefore, the object of the present invention is to receive voice analog signal and digital data signal through LAN cable installed in office, home, etc. everyday, and to transmit voice analog signal to MFC telephone which is used in daily life, and to computer. It is to provide a composite signal processing wall jack capable of transmitting digital data signals.

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

1 is an exploded perspective view of a composite signal processing wall jack for transmitting a voice analog signal / digital data signal according to an embodiment of the present invention. As shown in FIG. 1, a composite signal processing wall jack according to an embodiment of the present invention includes a board 10, a connection block 12, a splitter circuit 14, an RJ-11 connector jack 16, and an RJ-45. Connector jack 18;

The board 10 electrically connects the connection block 12, the splitter circuit 14, the RJ-11 connector jacks 16 and the RJ-45 connector jacks 18 to each other, and furthermore, they are physically compact. It is to integrate. The connection block 12 is connected to a LAN cable wired in a building such as a home or an office, and receives a voice analog signal and a digital data signal simultaneously transmitted from the LAN cable. Various connection means for receiving a signal from a LAN cable can be used. For example, in the simplest case, eight strands constituting the LAN cable may have a structure in which the strands are simply bonded to the substrate by a method such as soldering, but the convenience of wiring connection work, the ease of wiring coupling and disconnection, and the wiring Considering the tightness of the coupling, it is preferable to use stripping technology connector blocks (IDT: Insulation Displacement Technologies) such as 110D connector blocks.

An audio analog signal and a digital data signal input through the connection block 12 are input to the splitter circuit 14 through the substrate 10. The splitter circuit 14 includes a high frequency data signal and a low frequency analog voice through LAN lines and connection blocks 12 of 8 strands (GND, VCC, Tx +, Tx-, Rx-, Rx +, VCC, GND). The signals are mixed and input, and the splitter 14 analyzes the frequencies of the synthesized signals, and recognizes high frequencies as digital data signals and low frequencies as analog voice signals. The analog voice signal is transmitted to the RJ-11 connector 16, and the high frequency digital data signal is transmitted to the RJ-45 connector 18. Such a splitter 14 may be composed of various circuits used for frequency separation, and simply, as shown in FIG. 2, signals of eight wires inputted through a LAN cable may be signal lines Tx +, Tx-, Rx-, Rx +) and each of the four wires of the power supply lines VCC and GND, and branching the four signal lines again, one of the branched lines passes through the low pass filter 32 to select only the voice analog signal, and then the RJ- The other one of the branched lines passes through the high pass filter 34 having a DC blocking circuit, selects only the digital data signal, and transmits the same to the RJ-45 connector jack 18. At this time, the power lines VCC and GND separated from the LAN cable are combined with four wires for transmitting the digital data signal passing through the high pass filter 34 and connected to the RJ-45 connector jack 18. RJ-11 connector jacks (16) and RJ-45 connector jacks (18) are connector jacks commonly used for telephone line connection and LAN line connection. They are connected to general MFC telephone line and LAN line, respectively, and are used for voice analog signals and digital Transmit data signals to the LAN cards of telephones and computers.
