In general, the term "trunk line" refers to a line from the exchange facility of a broadcasting communication carrier to the trunk line terminal box. Fiber cables or coaxial cable are used as the material of the trunk line, and telephone lines, UTP cable, or coaxial cable are used as the material of the trunk line. Recently, in order to improve the quality of communication, the material of CO line is unified with optical fiber.

Optical fiber is a medium of optical communication as glass fiber, and telephone line, UTP cable and coaxial cable are copper wire and medium of telecommunication. An ONU (Optical Network Unit) or an ONT (Optical Network Terminal) is a device used to convert optical communication signals of optical fibers and electrical signals of copper wires.

In the case of small buildings, a trunk terminal box is installed. In a multi-family house, a trunk terminal box and a device box are simultaneously installed. The public line installed in the trunk terminal box is a telephone line or UTP cable, and the public line installed in the equipment box is often a coaxial cable. In the present invention, both the trunk line terminal box and the apparatus box are referred to as a trunk line terminal box for convenience.

In Korea, there is a fierce competition for attracting subscribers by broadcasting service providers. For this reason, subscriber lines, which are the trunk lines of many broadcasting and telecommunication carriers, are installed in one small building or multi-family house. The interior space of a trunk terminal box installed in small buildings or multi-family houses is narrow.

The trunk line is an optical fiber or a coaxial cable, and the trunk line is a telephone line, a UTP cable, or a coaxial cable. According to the regulations on technical standards for broadcasting communication equipment, the trunk line must be connected to the trunk line and the user household through connection with the trunk line.

However, in the case of small buildings or multi-family houses, there are many ways to install an Internet subscriber line that installs a distributor on the outer wall or rooftop of a building and connects the Internet subscriber line via the distributor to a direct user through a window or a veranda. Has come.

This method of installing the subscriber charity has caused social problems in which the subscriber charity is refrained from airing in the city alley, and thus, the subscriber charity is carried out every year by paying a lot of money, but the maintenance effect is not great, There is a problem that is refluxed later.

The interior space of the trunk terminal box installed in small buildings or multi-family houses is relatively narrow. Therefore, it is difficult to house all the ONUs that are individually deployed for each operator, and it has been difficult to commercialize ONUs for small buildings connected to various east-west extensions.

Accordingly, it is a reality that telecommunication carriers can not establish a communication line to the user terminal through a public line through an ONU for each operator, which is led into the trunk terminal box of a small building.

In order to solve these problems, the inventor of the present invention has found that, in order to solve these problems, the present invention provides a subscriber charger having a structure in which a common pole of a pole is installed, all the coaxial lines of broadcasting communication carriers are unified with optical fibers, There is a fact that I applied the installation structure.

First of all, there are difficulties that all trunk lines should be unified by optical fiber.

Second, there are difficulties that the trunk line terminal box is too narrow because all the ONUs required for connecting the optical fiber trunk line and the trunk line trunk are disposed inside the trunk line trunk box.

Third, there is a difficulty in commercialization of ONUs for small buildings suitable for connection to a public line having various conditions inside a narrow trunk terminal box.

It is an object of the present invention to provide a connection device of a CO line and a public line which contribute to the prevention of a safety accident and a public viewing of a residential area of a public welfare by allowing a broadcasting communication service provider to easily carry out a connection work of a CO line and a public line in the CO line terminal box have.

It must be interpreted in terms of meaning and concept.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. The same reference numerals are used for the same components, and only the different portions are described for the sake of clarity.

As shown in Figs. 1 to 3, a common extension A is arranged inside the trunk line terminal box 100. As shown in Fig. This far east extension A is one of a coaxial cable, a UTP cable or a telephone line.

In the embodiment of the present invention, the fixed board 130 is covered and fixed in the trunk line terminal box 100. It is preferable that the fixed substrate 130 is fixed to the inside of the trunk line terminal box 100 with a gap 140 interposed therebetween so as to have a necessary space on the upper surface of the same. The gap member 140 may be a separate columnar member disposed or fixed on the back surface of the fixed substrate 130 or may have a structure formed by folding both sides of the fixed substrate 130 though not shown.

A trunk line 160 connected to the trunk line of the trunk line terminal 100 and connected to the trunkline trunk box 100; a connection board 150 disposed and fixed at the middle of the fixed board 130; And an inner wire portion 170 which is connected to the coaxial extension A located on the other side of the connection strip 150 and connected to the user generation are important features of the present invention.

An electric circuit for supplying a current required for operation of communication devices connected to the power supply unit E and disposed in the CO line unit 160 is connected to the connection board 150 disposed and fixed in the middle part of the fixed substrate 130, Electrical terminals for electrical connection are provided at predetermined positions of the electronic apparatus. In addition, the connection strip 150 is provided with a communication circuit for interconnecting communication devices disposed in the CO line 160 and the OLT 170, and electrical terminals for establishing communication at a predetermined position of the communication circuit.

The CO line unit 160 is a component unit to which a CO line leading to the CO line terminal box 100 is connected. There are optical fiber and coaxial cable in the trunk line of the company. An optical communication signal is transmitted to the optical fiber and an electrical communication signal is transmitted to the coaxial cable.

The optical communication signal transmitted to the optical fiber trunk line must be converted into a telecommunication signal suitable for the tangential extension A in order to be transmitted to the user household through the tangential extension A, To be transmitted to the telecommunication facilities through the optical communication network.

Is a photoelectric conversion communication device in which an ONU (Optical Network Unit) or an ONT (Optical Network Terminal) is used for mutual conversion between an electrical communication signal and an optical communication signal. An ONU includes an RFoG Node, a VDSL ONU, or a GEPON ONU. In the ONU, a master or an aggregation multiplexer is omitted.

An ONU is generally used as a photoelectric conversion communication device for a fiber optic cable trunk inserted into the trunk line terminal box 100.

In the embodiment of the present invention, commercial ONTs 161 for optical fiber CO trunks are arranged and fixed to the CO line 160 and connected to the electrical terminals and the ONT electrical terminals 161a disposed on one side of the connection board 150. The provider ONTs 161 are supplied with electricity necessary for operation through connection with the electrical terminals of the connection board 150. A master 171 (Master) is connected to the master electric terminal disposed on the other side of the connection strip 150. The ONT electric terminal 161a and the master electric terminal are connected to the communication circuit 153. [

The optical communication signal transmitted through the optical fiber trunk line is converted into an electrical communication signal via the ONT 161 and is transmitted to the master 171 via the communication circuit 153 connecting the ONT electrical terminal 161a and the master electrical terminal . Conversely, an electrical communication signal via the communication circuit 153 is converted into an optical communication signal via the ONT 161, and is transmitted to the communication equipment of the service provider.

The ONT 161 for the coaxial cable trunk that is drawn into the trunk line terminal box 100 need not be installed. This is because the telecommunication signal is transmitted to the coaxial cable trunk line.

The masters 171 disposed in the inner line section 170 are connected to one band determiner 171a connected to the master electric terminal of the connection strip 150 and two double inner line terminals 171b connected to the east extension line A , And a collective distribution communication circuit is disposed between one band determiner 171a and two times of earth line terminals 171b.

The band determiner 171a of the master 171 is connected to the master electric terminal of the connecting strip 150 and the earth terminal 171b is connected to the common earth stations A and connected to the user household Slaves 180 are installed.

In Korea, a lot of domestic and foreign co - operators enter the small building. A plurality of masters 171 are arranged and fixed in the master section to maintain the independence of the provider communication line. It is also possible that one provider ONT 161 is connected to one or a plurality of masters 171.

The east extension (A) is a coaxial cable, a UTP cable or a telephone line, whereby the frequency range of the transmissible electrical communication signal is changed. Therefore, the master 171 and the slaves 180 are separately manufactured according to the type of the same. The ONT 161 to which the optical fiber trunk line is connected is also manufactured independently for each provider. This is because operating systems of broadcasting and telecommunication facilities are different for each broadcasting service provider.

The ONU is a communication device in which the ONT 161 and the master 171 are combined. An appropriate ONU for a commercial fiber-optic trunk line to be introduced into the trunk terminal 100 of the small-scale building is not commercialized. This is because it is not realistic to commercialize a separate ONU according to the type of the various PSTN (A) for each business operator.

On the other hand, the ONT 161 used when the optical fiber is connected to the user generation is commercialized for each business. The master 171 and the slave 180 according to the type of the common extension A can individually connect to the ONTs 161 according to the provider through the connection strip 150 to perform the function of the ONU It is.

Thus, according to the present invention, various types of ONUs are configured for each trunk line terminal box 100 of a small-sized building having a relatively small space, thereby realizing the construction of a communication line through the tongue extension line (A) And the like.

The arrangement of the masters 171 on the upper surface of the fixed substrate 130 allows the optical fiber coaxial lines B of different broadcasting communication companies to be drawn into one trunk line terminal box 100, Space of the ONTs 161 to be connected to the optical fiber trunk lines B to be connected to the trunk line terminal box 100 by using the space effectively.

The casing of the fixed substrate 130 and the master 171 is made of aluminum. Aluminum has a high thermal conductivity, which helps dissipate the heat generated by the operation of the communication circuit to the outside to cool it.

4 and 5, the depth of the CO line terminal 100, which has been previously embedded in the building wall, is too shallow to cover the door with the ONT 161 or the master 171 being accommodated therein, If it becomes difficult, the door is removed, and the additional frame 200 and the additional door are additionally provided on the outer side to enlarge the inner space while minimizing the degree of protrusion of the trunkline terminal box 100 from the wall surface It is possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
