Description

Generation communication terminal box {Wall-buried-in Communication Box}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a generation communication terminal box. In particular, power dissipation systems such as power adapters, power line modems, cable-data optoelectronic converters, and home gateways are installed to suppress an increase in temperature inside the generation communication terminal box. And a generation communication terminal box.

As the desire for information and communication is urgent, especially as the ripple effect by the government-led high-speed information and communication building emblem certification system is in full swing, new buildings are installing household communication terminal boxes for each house, and the space within the household communication terminal box. Becomes the hub of the home molded wiring. That is, the UTP LAN cable molded wiring is separated from the generation communication terminal box and connected to the room, the living room, and the kitchen, and the RJ45 jack for data communication is installed in the room, the living room, and the kitchen, and the UTP cable is connected to the RJ45 jack. These LAN cables run round the house, gathering into household telecommunication terminal boxes installed in kitchens and porches. On the other hand, in the household communication terminal box, a communication line for connecting Internet communication and a voice line for connecting a voice telephone are introduced from the outside.

Conventionally, it was a general situation that a simple contact branch terminal (for example, 110 blocks) is installed in a generation communication terminal box without using power. Block 110 forms a 1: 1 contact between one wire drawn outside the home and one cable inside the home. However, as information and communication advances, especially as digital home networking progresses, transmission equipment capable of supporting various transmission methods, such as fiber-to-the-home (FTTH) and home power line communication, can be installed in the generation communication terminal box. In addition to the necessity to be installed, intelligent home gateway, a gateway system that manages Internet access services and acts as a home switching, also needs to be installed in the home generation communication terminal box. Furthermore, the intelligent home gateway is equipped with a central processing unit (CPU), memory, and nonvolatile memory. By using the computational resources, a hard disk drive is attached to the home gateway to provide an IP (Internet Protocol) network attached storage (NAS) function. There is also a desire to realize economic feasibility. Therefore, transmission equipment and intelligent home gateway that can support various transmission methods such as FTTH and home power line communication are installed inside or next to the generation communication terminal box.

When an optical cable is introduced into the home, an OE (Optical-Electronic) module for converting an optical signal into an electronic signal and vice versa is installed in a generation communication terminal box. In particular, when the optical cable is introduced into the home, it should be noted that the communication data signal and the cable broadcast wave are often superimposed on the optical cable by a wavelength multiplexing method. In this case, the OE module should be installed in the household communication terminal box. The OE module separates the optical signal from the outside into the home by separating the wavelength into an optical signal containing the cable broadcast wave and an optical signal containing the data, and then converts the optical signal containing the cable broadcast wave into an electrical signal to convert the coaxial cable signal (general cable). It converts the broadcasting wave into a home and sends the optical signal containing the data to an electrical signal and sends it to the home gateway. The OE module receives data communication electrical signals from the home gateway through the UTP cable and converts them into optical signals. OE modules that perform this function consume about 20 watts of power. In addition, some home appliances may be efficient to operate simply by using low speed home power line communication. In this case, the home gateway system also serves as a power line communication (PLC) bridge function, and the generation communication terminal box should include a PLC module. This PLC module consumes about 3 watts. The intelligent home gateway consumes about 10 watts. If you add a hard disk storage device to make the home gateway function as an IP NAS, it consumes about 20 watts. In addition, power adapters for supplying DC power to these systems and modules consume at least 8 watts of power. In other words, the sum of power consumption of various systems installed in the household communication terminal box is about 50 watts.

However, it is common practice that generation communication terminal boxes are embedded in walls in terms of aesthetics or space efficiency of residential / office spaces such as offices and apartments. If a power consumption of about 50 watts is constantly consumed in a generation communication terminal box that is buried in a wall and is actually enclosed, this increases the temperature in the terminal box and eventually causes a failure of the system installed in the generation communication terminal box.

To solve this problem, a fan can be installed and forced ventilation to prevent the failure of the system installed in the household communication terminal box. In this case, however, there is a problem in that the operation state of the fan must be monitored and managed separately, and the noise by the operation of the fan is high.

It is therefore an object of the present invention to provide a generation communication terminal box configured to naturally dissipate or cool heat in a generation communication terminal box generated by power dissipating systems that do not use a fan.

In order to achieve the object of the present invention, the household communication terminal box, buried in the building wall, the housing consisting of a bottom surface, the upper and lower left and right sides in vertical contact with the floor surface and an open surface corresponding to the floor surface, and the A door for covering the open surface of the enclosure to prevent the electronic elements installed in the enclosure from being exposed to the interior space of the building, wherein at least one of the surfaces of the door facing the bottom of the enclosure (rear of the door) It is equipped with one or more power consumption systems. In addition, the rear of the door is further equipped with a light emitting element for detecting the operating state of the at least one power consumption system, the surface of the door, the surface exposed to the indoor space (front of the door) by using the light emitting element It is equipped with a display indicating the operating state of the detected power consumption systems.

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

1 is an exploded perspective view of a generation communication terminal box according to an embodiment of the present invention, Figure 2 shows a state in which the power consumption system is mounted on the door of the generation communication terminal box of Figure 1 in detail, Figures 3a and 3b is shown in FIG. Detailed diagram of system case and power strip shown.

The generation communication terminal box includes a housing 10 embedded in the building wall 18 and a door 20 for preventing the electronic elements 14, 15, etc. installed in the housing 10 from being exposed to the interior space in the building. The enclosure 10 includes a bottom surface 11, top, bottom, left and right surfaces 12a to 12d in vertical contact with the bottom surface 11, and an open surface 17 corresponding to the bottom surface 11. On the bottom surface 11 of the enclosure 10, a non-power consumption element including a 110 block 14 and a power socket 15 are attached. On the top, bottom, left and right sides 12a to 12d, they come out of the 110 block 14, A hole 13 through which a UTP cable 16 to be connected to an RJ45 jack installed in a room such as a living room or a kitchen is drawn out is formed. In FIG. 1, the UTP cable 16 is drawn out through the hole 13 formed in the lower surface 12a for convenience.

 The door 20 is made of a metal having high thermal conductivity, for example, aluminum, and includes a door window 22 and a frame 21 into which the door window 22 is fitted. And the door window 22 fitted to the frame 21 closes the open surface 17 of the enclosure 10, thereby preventing the electronic elements installed in the enclosure 10 from being exposed to the interior space in the building, thereby aesthetics of the building wall. Keep it. The door window 22 is provided with a fitting piece 28 and a hinge 25 for fixing the door window 22 to the frame 21 so that the door window 22 can be tacked. The hinge 25 is installed at right angles to the ground. As shown in Figure 1 may be installed horizontally on the ground.

Since the enclosures 10 are usually embedded in the wall 18, the enclosure 10 is substantially closed by the door window 22. In the enclosure 10, not only 110 blocks 14, which are non-power consumption elements, but also systems in which power consumption is generated, such as built-in modules and storage systems related to power and data transmission, are installed. Accordingly, heat is generated in the enclosure 10 according to power consumption of about 50 watts. Therefore, the temperature inside the enclosure 10 rises and the temperature of the non-power consuming system and the power consuming systems installed therein continues to increase, resulting in system failure or inoperability. If the door window 22 of the enclosure 10 is opened at regular intervals, the electronic elements in the enclosure 10 are cooled to room temperature, thereby preventing a malfunction of the electronic elements in the enclosure 10 due to a temperature rise. Opening (22) at regular intervals is cumbersome and inefficient. It is also undesirable for the wall aesthetics of the indoor space of the house. Thus, in the present invention, the heat generated from the power consumption system in the enclosure 10 is naturally released toward the interior space in the door window 22 so that the power consumption system is naturally cooled. That is, in the present invention, the heat generated in the power consumption system 33 by installing the power consumption system 33, such as the home gateway, power adapter, PLC modem and OE module in the door window 22 in contact with the indoor air Since it is transmitted to the room through the window 22, the power consumption system 33 is naturally cooled even if the enclosure 10 is closed by the door 20. Meanwhile, the power consumption systems 33 are integrated in the printed circuit board and installed in the system case 23 mounted on the rear surface 22b of the door window 22. Here, the rear surface 22b of the door window refers to the surface opposite to the bottom surface 11 of the enclosure 10, hereinafter referred to as the "rear of the door", and the front surface 22a of the door window refers to the surface directly contacting the indoor air. In the following description, it is referred to as "front surface of the door".

Specifically, at least one power consumption system 33 is mounted on the rear side 22b of the door. The power consumption system 33 is integrated in a printed circuit board and varies in size depending on its type and manufacturer. In addition, the rear surface 22b of the door is equipped with a power consumption system 33, a power supply power strip 34, and a light emitting device (not shown) such as an LED for sensing an operation state of the one or more power consumption systems. It is preferable that the light emitting element is also integrated in the printed circuit board. In addition, the front part 22a of the door is equipped with a display unit 24 indicating an operating state of the power consumption systems sensed using the light emitting device. Therefore, it is possible to check the operating state of the various electronic elements inside the enclosure 10 without opening the door 20. On the other hand, the display unit 24 is installed on the front surface (22a) of the door, but the installation position is not limited to this may be installed on the surface of the system case (23).

For example, the power dissipation system 33 is secured in the system case 23, which is secured to the rear face 22b of the door, as shown in FIG. 2. The system case 23 is fastened to the door window 22 by being fastened to a plurality of male screws 32 mounted on the rear surface of the door at predetermined intervals. Looking more specifically, an example of the system case 23 is shown in Figure 3a. As shown in FIG. 3A, the system case 23 includes a main body 23a having a hexahedron shape with one surface open, and both male extension parts 23b of the open portion are provided with a male screw installed at the rear surface 22b of the door. An insertion hole 23c to be fitted is formed. In addition, a matrix wire mesh frame 23d is installed in the inner space of the main body 23a to protect components on the printed circuit board during assembling or disassembling the system at the rear of the door, and to secure the mechanical dynamic structure of the case 23. Since the bottle 23d is reinforced and the air communication is smooth, the heat can be transferred to the door well. In addition, the material constituting the system case 23 is not particularly limited, but when manufactured with a material having low thermal conductivity such as plastic, it is not only excellent in economy but also effective in blocking heat transfer to the enclosure 10. .

Next, referring to FIG. 3B, the power strip 34 mounted on the rear surface 22b of the door window 22 is a power strip 34 extending from one side of the main body 34a and the main body 34a. 34e, the main body 34a includes an AC input socket 34d for connecting to an external power source, an AC output terminal 34b for connecting an external power source to a power adapter mounted on the rear side 22b of the door, and A case-type fuse 34c is formed to prevent excessive power consumption by a general user, and an extension hole 34f is formed with an insertion hole 34f into which a plurality of male screws installed on the rear surface 22b of the door are fitted. . To supply external power to the power consumption system, open the door as shown in FIG. 2, and then connect an external power supply line drawn from the wall to the AC input socket 34d of the power strip 34, and the power adapter of the corresponding power consumption system. To the AC output terminal (34b) and to the power adapter and power dissipation system. On the other hand, since the power supply power strip 34, the power adapter and the power consumption system are all installed on the rear surface 22b of the door, a plurality of AC connection cords may be complicatedly installed between the door and the bottom surface 11 of the enclosure 10. There is no need.

On the other hand, in the system case 23 and the power supply power strip 34, a part of the plurality of male screws provided in the rear surface 22b of the door window 22 is inserted into the predetermined insertion holes 23c and 34f to the door window 22. It is intended to be mounted. Since the male screws are prepared and embedded in a sufficient number in advance at predetermined intervals, even if the systems are replaced in the future and the size of the case 23 is changed, the system can be installed without replacing the existing door window 22. Since the male thread is about 5 to 10 millimeters in height, the male thread used for the small system may exist between the rear 22b of the door window 22 and the wire mesh frame 23d in the large system case.

1 to 3B, the case in which the system case 23 and the power consumption system 33 are installed on the rear surface 22b of the door without penetrating the door window 22 has been described. However, the present invention is not limited thereto. It is also possible to install the system case 23 through the door window 22 and through which the power consumption system is installed, and fix it to the door window 22. Such examples are shown in FIGS. 4A and 4B. 4A and 4B, a predetermined portion of the door window 42 is penetrated so that the system case 43 in which the power consumption system 53 is installed is fixed to the door window 42 by the fastening member 45. do. Fastening member 45 may be used a variety of known fastening members such as bolts and nuts. The system case 43 may be formed to protrude from the front side 42a and the rear side 42b of the door as shown in FIG. 4A, and coincide with the front side 42a of the door and toward the rear side 42b of the door as shown in FIG. 4B. May be formed to protrude. In the case of FIGS. 4A and 4B, since the power consumption system 53 is installed inside the system case 43 in direct contact with the indoor air, the power consumption system 53 may be naturally cooled. A light emitting device (not shown) for detecting an operating state of the power consumption system is mounted on the rear surface 42b of the door, and an operating state of the power consumption systems detected using the light emitting element is mounted on the front surface 42a of the door. A display section 44 indicating is mounted.

Although not shown in FIGS. 1 to 4B, when a part of the door edge is cut out to form a through hole through which a power line or voice line can penetrate, the housing 10 is provided with an xDSL modem outside the generation communication terminal box through the through hole. From the modem, the voice lead line and the power supply can be connected, and the voice line and data line can be connected from the modem back into the enclosure. In addition, in FIG. 1 to FIG. 4B, a case of mounting a power consumption system using a single door is illustrated, but a power consumption system may be mounted using a system in a double door. The double door is composed of the inner door and the outer door, and the inner door may cover the whole housing or only the housing part as shown in the figure. Then, the system case with the power consumption system is mounted on the speed gear. The outer door covers the speed gear and / or the exposed enclosure to enhance the aesthetics of the enclosure 10, and the display unit may be installed on the outer door.

According to the above description, the generation communication terminal box having an exposure type door according to the present invention is capable of dissipating heat without installing a fan by installing various systems or modules in the door, so that the generation communication terminal box is effective and efficient for home communication. It can now serve as a hub for the system. In addition, since the heat generated by the power consumption system is naturally cooled through the door, the system case covering the power consumption system can be made of plastic, so that heat transfer to the enclosure can be effectively performed without increasing the manufacturing cost of the generation communication terminal box. You can block. Since power strips are installed on the back of the door, even if multiple power consumption systems are mounted on the back of the door, one cord is sufficient for the AC connection cord between the door and the bottom of the enclosure.

In addition, the display units 24 and 44 are disposed on the front of the door covering the enclosure 10 so that the user can easily check the operation state of various systems in the household communication terminal box without opening the enclosure door. In addition, by installing a plurality of male screws on the rear of the door and the system case and the power strip to be attached to the male screw, other systems of different sizes and manufacturers can be easily attached to the rear of the door.

It is common that the depth from the wall to the bottom of the enclosure is about 120 millimeters. Since the power consumption electronic modules mounted on the door 20 or the system in which they are installed are about 24 to 50 millimeters thick, the remaining depth of the enclosure (10) Since various electronic components including non-power consumption electrons can be installed in the space, the space of the enclosure 10 can be utilized in three dimensions.

Furthermore, the predetermined number of screws 32 are driven in advance at appropriate intervals based on the size of the generation communication terminal box, the type and size of the output voltage and current of the power adapter, and the builder or the user selects various systems of different manufacturers.
