Wall-mounted access point {ACCESS POINT BURIED IN WALL}

The present invention relates to an access point, and more particularly, through an installation structure that actively utilizes a switch box embedded in a building wall and a wired / wireless internet communication environment, the Internet communication in each living room and each room is simply installed. It is about wall-mounted access points that can build environments and residents can freely choose to use wired or wireless Internet communications anywhere in the household.

With the development of electronic devices and the proliferation of high-speed Internet, the Internet has become an indispensable communication environment for individuals, and beyond the era of having one computer for one generation, many electronics including computers and laptops for one generation The device is installed and used.

Accordingly, in order to simultaneously access the Internet environment, a plurality of households may purchase or install a separate router, additionally install an outlet for internet access on a wall of each room, or install a wireless AP repeater. Work was needed.

However, since the outlet outlet method in the conventional generation requires piping and wiring construction separately from the telephone / TV outlet, there is a problem in that construction is duplicated, management efficiency is lowered, and cost is increased.

In addition, conventional routers and wireless APs are exposed as they occupy the interior space, especially when using a router to provide Internet communication environment in each room, because the LAN line is long stretched, not only harm the interior aesthetics. But there was a problem of constraining the activity space.

In addition, since the conventional wireless AP provides only the wireless network function, the user may not use the wired or wireless communication environment selectively.

The present invention has been made to solve the above problems, the object of the present invention does not need to purchase and install a separate Internet router, in particular, to provide an Internet environment anywhere in the household without additional communication line construction and power construction It is to provide a wall mounted access point that can be.

It is still another object of the present invention to provide both wired and wireless Internet communication environments with only one device, and to provide a wall-mounted access point where residents can freely use wired or wireless Internet communication anywhere in the household. will be.

Still another object of the present invention is to allow the device itself to be installed embedded in the wall portion, thereby preventing the active space constraints caused by the device exposed to the indoor space and to improve the overall aesthetics of the interior space It is to provide an embedded access point.

Wall-mounted access point according to the present invention for achieving the above object is a sub-PCB board having a WAN port on one surface; A main PCB board electrically connected to the sub PCB board and having a LAN port at one surface thereof; A lower case having an open side, the lower case accommodating the sub PCB substrate and the main PCB substrate therein; It is coupled to the open one side of the lower case, is fastened to the switch box, the first drawing hole for drawing out the LAN port of the main PCB board to the outside in a predetermined area is formed through, the antenna is integrally on the inner side An upper case which is inserted and attached; And an exterior cover that closes one surface of the upper case and exposes an appearance on a building wall, and a predetermined opening has a second drawing hole for drawing out the LAN port to the outside of the wall. In addition, a hole is formed in the lower case, and the WAN port of the sub-PCB board is disposed opposite to the hole, so that the data cable introduced into the switch box can be connected to the WAN port through the hole. It is characterized in that it is configured to.

According to the wall-mounted access point according to the present invention, by actively utilizing the standard switch box installed in the wall of each room during the construction of the building, the living room and easy installation just installed in the existing switch box without a separate communication line work and power construction Internet communication environment can be established in each room. As a result, the construction cost of the Internet communication environment can be substantially reduced, and the occupants can easily access the Internet from any room without having to install and install a separate Internet router.

In addition, there is a remarkable effect of realizing a convenient communication environment that can be used freely as well as wired Internet connection anywhere in the household.

In addition, through the structure that the TV, telephone, Internet connection terminals are all buried in the wall in the form of a switch, there is a remarkable effect that can improve the overall aesthetics of the interior space.

In addition, the data cable inserted into the switch box of the present invention is guided by the guide socket and can be connected to the WAN port accommodated therein, so that it is not entangled with other wires inserted into the switch box or stably connected. It has the advantage of maintaining state.

In addition, through the fitting protrusion and the fitting groove formed in the upper case, as the fitting is coupled with the neighboring arrangement is formed, there is an advantage that can be mounted on the switch box while maintaining a firm coupling state without shaking.
