Description

{Customer device box for information and communication remodeling of apartment}

[0001] The present invention relates to a terminal housing (1) apparatus for remotely housings for information and communication remodeling, and more particularly, The modular unit 23 can be mounted and connected to a separate electronic device so that the user can freely use it. The operator can easily know that the connection of the power source or the signal is smooth by turning on the lamp without a separate device like a tester, As the cover is slid to the left and right, sliding and moving can facilitate the replacement or inspection of the internal apparatus without any separate tool, which can shorten the installation work time of the generation terminal box 1 and shorten the maintenance work (1) apparatus for apartment house for information and communication remodeling.

Generally, apartment houses (apartments, multi-family houses, etc.) are composed of one living room and two to four bedrooms depending on the area. In the case of apartment houses (hereinafter referred to as "apartment houses") built before the rapid development of information and communication technology, piping and wiring for communication of telephones and the like in each living room and bedroom are connected by bus wiring It was installed using a TIV cable that is a communication cable.

That is, in the case of the old common house, the household terminal box 1 is not provided for each household. Therefore, in order to provide high-speed information communication service in the common house in the past, a method of installing a 4-pair UTP cable from the intermediate terminal box to the first outgoing entrance into each household is provided so that the UTP cable can be used only in one place .

Therefore, in the case of the former apartment house, except for the one where the first outlet is installed, in the other bedroom or the living room, the conventional multi-wiring method is used as it is, and the high speed information communication service can not be used. Recently, in order to promote the spread and awareness of high-speed information communication in the country, it is necessary to establish a certification mark (in the case of apartment buildings and commercial buildings) Emblem) is given to the emblem system. Accordingly, when building a new residential and commercial building of a certain size or larger, an internal communication facility is designed and installed to meet the examination standard in order to certify the emblem.

However, in the case of apartment houses in the past, bus wiring is used instead of STAR wiring, and T-AV cable is used. Therefore, it is not possible to build on-site communication facilities required by the examination standards of the emblem system. In the past, in the case of the conventional apartment house, since the household terminal box 1 for forming wiring is not provided, a hole is formed in the wall by using a tool such as a drill in order to install the household terminal box 1, This type of installation method requires a drilling operation such as a drill on the wall of the concrete, so that the installation work is difficult and requires a lot of working time, and noise, dust, vibration And the like, thereby causing inconvenience to the residents of the surrounding apartment buildings as well as the apartment houses during the installation work.

In order to solve such a problem, a wiring hole 11 is formed on the rear surface corresponding to the existing outlet box 40 (30) formed in a box shape, and on the back surface where the wiring hole 11 is formed The first engaging hole and the second engaging hole corresponding to the fixing hole 33 of the fixing protrusion 32 formed on the upper and lower sides of the outlet boxes 40 and 30 on the upper and lower sides with respect to the wiring hole 11 are A lid 4 on which one edge of the body 10 is rotatably coupled to open and close and a locking device 5 is installed on the body 10,

A plate-like fixing plate (20) having fastening holes (21) formed at positions corresponding to the joint holes and the second engagement holes and having a width smaller than the width of the wiring holes (11); Is fastened to the fixing hole 33 of the outlet box 40 or 30 through the fastening hole 21 of the fixing plate 20 and the first engaging hole or the second engaging hole of the body 10, A pair of fixing bolts 40 for fixing the supporting box 10 to the outlet boxes 40 and 30; A modular jack (90) installed on one side of the body (10); The first fitting hole formed on the upper side of the wiring hole (11) of the body (10) includes a first fitting hole formed in the body (10) 10 formed on the rear surface of the body 10 so as to correspond to the fixing protrusions 32 of the outlet boxes 40 and 30, The second engaging hole formed on the lower side is formed as a long left and right slot so as to move left and right in order to align the body 10 when fixing the body 10. The width of the fixing plate 20 can be freely varied, Wherein the width of the wiring hole (11) is larger than the width of the wiring hole (11) so as to extend the cable from the outlet box (40) (30) side, Can selectively be placed on the upper side or the lower side with respect to the outlet box 40 (30) The wiring hole 11 comprises a first wiring hole 11a and a second wiring hole 11b which are respectively formed on both sides with respect to a vertical direction on the back surface of the body 10, A first engaging hole 12a and a second engaging hole 13a are formed on the upper and lower sides with respect to the first wiring hole 11a and a first engaging hole 12a and a second engaging hole 13b are formed on the upper and lower sides of the second wiring hole 11b, The first wiring hole 11a and the second wiring hole 11b of the body 10 are connected to the outlet boxes 40 and 30 through the connecting hole 12b and the second fitting hole 13b, The first and second wiring holes 11a and 11b (not shown) on the outer surface of the inner and outer surfaces of the back surface of the body 10 are formed to prevent dust and foreign matter from flowing into the body 10 through the wiring holes, And the velcro tapes 6a and 6b are attached to the periphery of the first and second wiring holes 11a and 11b and correspond to the velcro tapes 6a and 6b around the first and second wiring holes 11a and 11b The velcro tapes 6a and 6b around the first and second wiring holes 11a and 11b are provided with the velcro tape 7a so as to block the first and second wiring holes 11a and 11b from the outside, The first and second wiring holes 11a and 11b used for securing to the outlet boxes 40 and 30 among the entire rear surface area of the body 10, The guide rails 8 are formed along the vertical direction on both sides of the inner surface of the inner surface of the back surface of the body 10 so that the oblique line terminal 50 can be installed on the entirety of the remaining regions except for the front surface 11a, A terminal position adjusting plate 60 capable of being slid along the guide rail 8 and capable of being selectively fixed at various sliding positions is provided and the oblique terminal 50 is installed on one surface of the terminal position adjusting plate 60 , The lid 4 is opened through an infant or a child The locking device 5 of the lid 4 is a constitution of an electronic locking device for controlling opening and closing operations by inputting a password or inputting of biometric information, A reflection sensor 70 for detecting the presence of an object approaching within a preset distance and an LED unit 70 for emitting light by operating in accordance with a signal output in response to the detection of an object approaching within a predetermined distance from the reflection sensor 70, (1) apparatus for communicating remotely housings for telecommunication remodeling, characterized in that it further comprises a communication terminal (80).

However, such a conventional apartment housing terminal box (1) apparatus is complicated in that installation work of the household terminal box (1) is completed through the relatively easy operation of fastening the fixing plate to the outlet box with fixing bolts or screws, and noise, However, there is a restriction that the electronic circuitry which can use a telephone line or the Internet can not be used as only one unit, and there is no power modular unit 23, so that a separate electronic device can not be used and the actual modular unit It is impossible to identify whether or not it is possible to do so, so that it is difficult for the operator to shorten the actual working time.

In addition, in order to perform a maintenance work or the like, it is necessary to open the cover 4 by opening the cover 4 from the body 10 through the lock device. In this case, when the password of the lock device is lost or the release device is lost, there was.
