Description

4-terminal telephone plug

The present invention relates to a telephone plug, and more particularly, to a four-terminal telephone plug that can be usefully used in ADSL construction by combining a jack with a conventional four-terminal telephone plug.

Currently, ADSL is widely used as an Internet access service used in homes and offices. ADSL stands for Asymmetric Digital Subscriber Line and is a network communication method that can transmit voice signal and digital data together on one telephone line. In FIG. 1A, using the ADSL service, a telephone line 11 is introduced into a telephone terminal box (MDF) 10 of a home or office at a telephone station, and digital data transmitted through the telephone line is transferred via a modem 12 to a PC. And to the telephone 15 via a low pass filter 14 at the same time.

On the other hand, in order to install ADSL in the home or office, the ADSL line is connected from the telephone office to the MDF of the building, and the installation engineer visits and opens the telephone outlet already installed in the building to operate the extension. Specifically, it is as follows. Fig. 1b briefly illustrates the existing in-building telephone line wiring. The terminal box 10 is connected to four telephone lines connected to the telephone station. The two strands are main lines 16 connected to the upper terminals (18a in Fig. 1c) of the four-pronged outlets 18, 18 ', ... embedded in the walls of each room and connecting the telephones, and the other two strands In the case where a problem occurs in the main line 16 as the spare line 17, the wire is preliminarily installed up to the inside of the outlet 18 so that the main line 16 can be easily replaced without the internal wiring work. In most cases, the spare line 17 is not connected to the terminal of the outlet 18, but extends only to the outlet filling box, so that the main line 16 can be easily replaced in case of emergency. In addition, telephone outlets 18, 18 ', ... in each room are bridged in parallel to each other so that telephones can be connected to each room.

Fig. 1C briefly shows a four-prong telephone outlet 18 which is widely used. Terminals of the upper terminal portion 18a are disposed with a wide interval, and terminals of the lower terminal portion 18b are disposed with a narrow interval to prevent erroneous connection with the plug. In most cases, the upper terminal portion 18a mainly serves to connect the telephone line, and the lower terminal portion 18b is not used. Existing four-terminal telephone plugs inserted and used in the telephone outlet 18 of Fig. 1C are well known and will not be described separately.

On the other hand, in order to install ADSL in a conventional building wired as shown in FIG. 1B, the installation engineer works as shown in FIG. 1D. In order to install the ADSL, the ADSL installer mixed with the data signal and the voice signal must be transmitted from the telephone station, so that the ADSL installer can use the spare line instead of the existing main line. Open the main telephone outlet 18 directly connected to the existing main line 16 is disconnected from the upper terminal portion 18a, and then the reserve line 17 is connected to the lower terminal portion 18b of the outlet. The ADSL data line 21 is connected to the lower terminal portion 18b and the " LINE " jack of the modem device 20, and the " PHONE " jack of the modem device 20 and the upper terminal portion 18a of the outlet 18 are connected. To the ADSL telephone line 22. In addition, the telephone station transmits the ADSL signal to the reserve line 17 instead of the main line 16 previously connected to the terminal box 10 of the building.

In this way, the telephones can be used in the same way as before by operating only the main outlets, without having to perform separate operations for the outlets 18, 18 ', ... for each room. You can receive ADSL service through (17). Of course, it must be through the low pass filter 14 before connecting the telephone 15 to the telephone outlet 18 as mentioned above.

However, in order to actually realize the wiring shown in Fig. 1D at the time of installation work, the four-terminal telephone plug to be inserted into the outlet 18 is opened to connect the ADSL telephone line 22 and the ADSL data line 21 to the upper terminal and the lower terminal, respectively. Since the installation, it takes a lot of installation time will reduce the installation efficiency. In addition, when the subscriber releases the ADSL service, the installation article and the telephone outlet 18 must be restored to its original state, which also causes a decrease in business efficiency.

The present invention devised to solve the above problems, by adding a separate jack to the existing four-terminal telephone plug, the installer opens the main telephone outlet as before, to separate the main line from the upper terminal of the outlet and to the bottom of the outlet The only purpose is to connect the spare wire to the terminal, and insert only the four-terminal telephone plug according to the present invention into this outlet.
