According to an embodiment of the present invention, a tensile line passing through the housing is fitted to the tensile line fixing portion, and the tensile line and the tensile line fixing portion are coupled to each other. The tensile wire is in contact with the inner surface of the tensile wire fixing portion, and the second tube surrounding the tensile wire is in contact with the outer surface of the tensile wire fixing portion and the surface of the tray. Thus, the housing is fixed to the tension line and does not move left and right and up and down in a standing state.

According to the embodiment of the present invention, the optical fiber drawn out from the first tube is fused with the optical fiber to which the connector is coupled without polishing, and the sleeve is wrapped and protected by the fused portion. Since the optical fibers are connected by the fusing method, the process of polishing the end of the optical fiber (drawn out from the first tube) does not occur. Therefore, it is possible to prevent the problem caused when the extracted optical fiber portion is twisted or broken during the polishing process, thereby preventing damage to the optical fiber.

According to an embodiment of the present invention, since the sleeve is not fixed to the tray, the sleeve can be moved downward by the load when it is erected on the housing. In this case, the optical fiber wound around the filament space is folded, and the curvature of the optical fiber becomes small. A light transmission loss occurs due to a decrease in curvature. However, since the sleeve is fixed to prevent the sleeve fixing portion from moving, the above problems can be prevented. The optical signal transmission rate can be improved.

According to the embodiment of the present invention, since the optical fiber is wound around the filament area by pulling one side or the other side of the first tube by winding the filament space formed in the optical fiber in a curved shape for easy storage, A gap is generated in the optical fiber, so that breakage can be prevented.

According to the embodiment of the present invention, even if the optical fiber drawn by the pulling of the first tube is damaged, the optical fiber is loosely wound around the filament area, so that the damaged optical fiber part can be removed and the connector can be reconnected with the connected optical fiber. Therefore, the optical fiber does not need to be replaced entirely in the first tube, which simplifies maintenance and reduces maintenance costs.

According to the embodiment of the present invention, the branch optical cable connected to the terminal device of the living space is detachably connected to the adapter of the FTTH home terminal box. Thus, although the optical cable portion which has conventionally been introduced into the living space is damaged, the optical cable has to be totally re-installed. However, in this embodiment, maintenance is easy by replacing only the branch optical cable.

According to the embodiment of the present invention, since the buffer part surrounds the housing, the housing does not directly bump against the outer wall due to external requirements such as wind. Thus, it is possible to prevent breakage, noise, and the like that may occur as the housing directly bumps against the outer wall.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like parts are designated with like reference numerals throughout the specification.

The FTTH home terminal box having a tensile wire fixing part according to an embodiment of the present invention can be applied to an optical signal transmission device which is an embodiment of the present invention. Hereinafter, an FTTH home terminal box having a tensile wire fixing part, Explain device mainly.

An optical signal transmission apparatus according to an embodiment of the present invention will now be described with reference to FIGS. 1 and 2. FIG.

FIG. 1 is an installation view of an optical signal transmission apparatus according to an embodiment of the present invention, and FIG. 2 is a partially enlarged view of the optical signal transmission apparatus shown in FIG.

1 and 2, an optical signal transmission apparatus 100 according to an embodiment of the present invention is installed on an outer wall of a building 1 to transmit an optical signal provided by a communication company to a building 1 living space 1a, 1b, (Not shown) disposed in the terminal devices 1c and 1c. The use of the optical signal transmission apparatus 100 according to the present embodiment makes it possible to easily construct an FTTH in an aged building. The construction of the branch cable 30 connecting the optical signal transmission apparatus 100 and the terminal apparatus can be determined according to the residential selection of the living space 1a, 1b, 1c.

The optical signal transmission apparatus 100 includes a first tube 10, a second tube 20, optical fibers 30a and 30b, a tension line 40, and an FTTH house terminal box 5 ) (Hereinafter referred to as FTTH home terminal box), an adapter 60 and a branch optical cable 70.

Referring to FIG. 3 in which the first tube and the second tube are enlarged, the first tube 10 and the second tube 20 are connected in parallel along the longitudinal direction. The length of the first tube 10 and the second tube 20 is determined according to the height of the building. One side of the first tube (10) and the second tube (20) are located at the lowest position of the building and the other side is located at the highest position.

Openings 11 and 21 are formed in the first tube 10 and the second tube 20, respectively. The number of openings 11, 21 may be equal to or greater than the number of living spaces 1a, 1b, 1c (see FIG. 1).

The spacing of the adjacent openings 11 of the first tube 10 and the spacing of the adjacent openings 21 of the second tube 20 may vary depending on the layer spacing of the building.

Each of the openings 11, 21 is formed by peeling off a part of the first tube 10 and the second tube 20. However, the openings 11 and 21 may be formed by cutting the first tube 10 and the second tube 20. The open portion 11 of the first tube 10 and the open portion 21 of the second tube 20 are apart.

A plurality of optical fibers 30a are formed and disposed inside the first tube 10 together with the aramid yarn (not shown). The number of the optical fibers 30a may be equal to or greater than the number of the living spaces 1a, 1b, 1c (see FIG. 1). The lengths of the optical fibers 30a are differently formed. For example, the first optical fiber length has a height of one layer of the building and the second optical fiber length has a two-layer height length of the building. The optical fibers 30a may have different colors depending on their lengths. Therefore, the installer of the optical signal transmission apparatus 100 can easily recognize the length of the optical fiber by viewing the color.

One side of the optical fiber 30a is located at one side of the first tube 10 and can be connected to a terminal box (not shown) connected to a communication company. And the other side of the optical fiber 30a is drawn out to the outside through the opening 11. [ An optical fiber 30b to which the connector 32 is connected is connected to the end of the extracted optical fiber 30a by a fusion method. Since the optical fibers 30a and 30b are connected by the fusing method, the process of polishing the ends of the optical fibers 30a to connect the connectors does not occur.

If the end of the optical fiber 30a is polished, the optical fiber 30a drawn to the first tube 10 during the grinding process may be bent or twisted. In this case, if the optical fiber 30a is damaged, the optical fiber 30a must be disposed again, resulting in an economical loss. However, in the case of this embodiment, since the optical fiber 30a is not polished, the above problem can be prevented.

A sleeve 31 is disposed at the fused portion of the optical fibers 30a and 30b. The sleeve 31 fixes the fused portions of the optical fibers 30a and 30b so as not to move. The sleeve 31 includes a covering member 311 for covering the optical fibers 30a and 30b and a reinforcing member 312 for preventing abrupt bending of the covering member 311. [ The covering member 311 may be made of resin and the reinforcing member 312 is disposed inside the covering member 311 and may be made of metal.

The tensile wire 40 is disposed within the second tube 20 and can be made of a metal having predetermined strength. A portion of the tensile line 40 is exposed through the opening 21 of the second tube 20. Both the tension line 40 and the second tube 20 are coupled to a fixing member (not shown) provided on the building so that tension can be maintained. The tension of the tension line 40 can maintain the state that the optical signal transmission device 100 is stably installed on the outer wall of the building without shaking even when a strong wind is blown.

Next, a description will be given of an FTTH home terminal box having a tension line fixing portion with reference to FIG. 4 to FIG.

FIG. 4 is an exploded perspective view showing the FTTH housing terminal box shown in FIG. 2, FIG. 5 is an enlarged view of the tray shown in FIG. 4, FIG. 6 is an enlarged view of the bottom of the tray shown in FIG. 8 is a cross-sectional view taken along line VIII-VIII of FIG. 7, FIG. 9 is an enlarged view of the sleeve fixing portion shown in FIG. 6, and FIG. 10 is a plan view of FIG. 9 .

4, the FTTH housing terminal box 5 is disposed at a portion where the openings 11 and 21 of the first tube 10 and the second tube 20 are formed, As shown in FIG. The FTTH housing terminal box 5 includes a housing 51, a tray 52, a guide portion 55, departure prevention portions 53 and 54, a tension line fixing portion 56 and a sleeve fixing portion 57 .

The housing 51 includes a pedestal 511, a lid 512, a cap 516 and a sealing member 517 when installed in a building in a standing state.

The pedestal 511 and the cover 512 are overlapped with each other and their edge portions are in contact with each other. One side of the pedestal 511 and the lid 512 are connected to each other by a hinge 513. The lid 512 can be moved to open and close relative to the hinge 513. A locking member 514 is formed on the other side of the pedestal 511 and the lid 512 to maintain the engaged state of the lid 512 and the pedestal 511.

The first tube 10 and the second tube 20 pass through along the longitudinal direction of the pedestal 511 and the openings 11 and 21 are connected to the inside of the housing 51.

The cap 516 is disposed at both side edges of the pedestal 511 and surrounds the first tube 10 and the second tube 20.

The sealing member 517 is disposed between the pedestal 511 and the edge of the lid 512. The sealing member 517 overlaps the cap 516. [ The cap 516 and the sealing member 517 may be made of rubber or the like having an elastic force. The cap 516 may not be made of rubber.

The cap 516 and the sealing member 517 can be pressed between the lid 512 and the edge of the pedestal 511 when the lid 512 and the pedestal 511 are joined by the locking member 514. Foreign substances such as rainwater can be prevented from flowing into the housing 51 by the cap 516 and the sealing member 517.

The tray 52 is formed with a hole 521 for connecting the one surface to the other surface and is disposed on the pedestal 511. The tray 52 is supported on a supporting stand 524 vertically projecting from the inner bottom of the pedestal 511. A space is formed between the lower surface of the tray 52 and the inner bottom surface of the pedestal 511 by the support table 524. The first tube 10 and the second tube 20 pass through the space.

The support base 524 is formed with an insertion hole 524a through which the insertion protrusion 525 protruding vertically from the lower surface of the tray 52 is inserted. The tray 52 may not be shaken in the housing 51 by the insertion protrusion 525 inserted into the insertion hole 524a.

The tray 52 is fixed to the pedestal 511 by a plurality of fixing projections 511a protruding inward from the edge of the pedestal 511. [

Referring to FIGS. 5 and 6, the upper and lower surfaces of the tray 52 are formed with filament areas 522 and 523, respectively, which are capable of winding the optical fibers 30a and 30b in a curved shape for easy storage. The optical fibers 30a are stored in the filament area 523 formed on the lower surface of the tray 52 and the optical fibers 30b are stored in the filament area 522 formed on the upper surface.

Since the optical fiber 30a drawn out of the first tube 10 is wound around the covering area 523 even if one side or the other side of the first tube 10 is pulled out, A clearance is generated in the optical fiber 30a, and breakage can be prevented.

In addition, even if the optical fiber 30a drawn out of the first tube 10 is damaged, the optical fiber 30a is easily wound around the filament area 523, so that the damaged part of the optical fiber is removed, The fibers 30b can be reconnected with the optical fibers 30a. Accordingly, the optical fiber 30a is not required to be replaced entirely by the first tube 10, so that maintenance and repair of the optical signal transmission device 100 can be simplified and the maintenance cost can be reduced.

The separation preventing portions 53 and 54 are formed in the filament regions 522 and 523 of the tray 52 so that the optical fibers 30a and 30b do not deviate from the filament regions 522 and 523. The optical fibers 30a and 30b can be fixed without moving in the covering areas 522 and 523 by the separation preventing parts 53 and 54. [

The separation preventing portions 53 and 54 include inner members 531 and 541 for supporting the inner side of the wound optical fibers 30a and 30b and outer members 532 and 542 for supporting the outer side. The pressing members 532a and 542a are formed on the outer members 532 and 542 so as to press and fix the optical fibers 30a and 30b on the upper surface and the lower surface of the tray 52, respectively.

The separation preventing portions 53 and 54 may be formed in various shapes such as a cylinder, a square column, and a plate. The shape of the separation preventing portions 53 and 54 may be changed according to the structure of the tray 52. [

The guide portions 55 are vertically protruded from both sides in the longitudinal direction of the bottom surface of the tray 52. The guide portion 55 guides the housing 51 through the housing 51 while the first tube 10 and the second tube 20 passing through the housing 51 are inserted. The outer circumferential surfaces of the first tube 10 and the second tube 20 can be brought into close contact with the tray 52 by the guide portion 55.

Further, the guide portion 55 fixes the first tube 10 and the second tube 20 in the raised housing 51 so as not to move. However, the tray 52 may be omitted. In this case, the covering areas 522 and 523 may be formed inside the housing 51.

6 to 8, the tension line fixing portion 56 includes a first bracket 561, a second bracket 562, a first projection 561a, and a second projection 562a.

The first bracket 561 and the second bracket 562 protrude vertically from the lower surface of the tray 52 and face each other at an interval. The portion of the tensile wire 40 exposed through the opening 21 of the second tube 20 is located in the yarns of the first bracket 561 and the second bracket 562. That is, the tension line 40 passes between the first bracket 561 and the second bracket 562 with the second tube 20 omitted. The tensile wire 40 can be in contact with the surface (inner surface) where the first bracket 561 and the second bracket 562 face each other according to the thickness thereof. The housing 51 erected thereon will not move in the left and right directions. The cross section of the second tube 20 positioned at both ends of the exposed portion of the tensile wire 40 can contact the outer surfaces of the first bracket 561 and the second bracket 562 of the tensile wire fixing portion 56 have. The tensile wire fixing portion 56 is caught by the second tube 20 and the raised housing 51 does not move in the upward and downward directions.

Since the outer surfaces of the first and second tubes 10 and 20 are in close contact with the tray 52 and the second tube 20 is in contact with the first bracket 561 and the second bracket 562, Can be fixed to the outer wall so as not to move.

The first protrusion 561a protrudes from the first bracket 561 toward the second bracket 562 and the second protrusion 562a is separated from the first protrusion 561a so that the second protrusion 561a is separated from the second bracket 562, (561). The tension line 40 does not separate between the first bracket 561 and the second bracket 562 by the first projection 561a and the second projection 562a.

Meanwhile, the first tube 10 connected to the second tube 20 contacts the first bracket 561. So that the first bracket 561 is positioned between the tension line 40 and the first tube 10. Accordingly, the first tube 10 and the second tube 20 may not move in the housing 51.

The tensile wire 40 can be fastened to the tensile wire fixing part 56 in a single process by inserting the tensile wire 40 into the tensile wire fixing part 56 so that the tensile wire 40 can be processed more simply and quickly than the process of bonding the tensile wire 40 to the tray 52.

6, 9, and 10, the sleeve fixing portion 57 is formed at a portion of the sleeve region 523 formed on the lower surface of the tray 52, and fixes the sleeve 31 so as not to move. The sleeve fixing portion 57 includes first to fourth brackets 574.

The first bracket 571 and the second bracket 572 are spaced apart from each other and vertically protrude from the bottom surface of the tray 52. [ The ends of the first bracket 571 and the second bracket 572 are bent vertically toward the inside of the tray 52.

The third bracket 573 and the fourth bracket 574 protrude vertically from the inside of the lower surface of the tray 52 and are spaced apart from each other. The third bracket 573 and the fourth bracket 574 face the first bracket 571 and the second bracket 572 with an interval. The sleeve 31 is positioned between the first and second brackets 572 and the third and fourth brackets 574. At least a portion of the sleeve 31 is fixed in the form of being pushed in contact with at least a portion of the first and second brackets 572 and the third and fourth brackets 574 to prevent movement. It is possible to prevent a problem that occurs in the fused portion of the optical fibers 30a and 30b due to the movement of the sleeve 31 due to the fixing of the sleeve 31. [

The sleeve 31 is also raised since the FTTH home terminal box 5 is erected when it is installed in the building. The sleeve 31 can be moved downward by a load. When the sleeve 31 is moved, the curved portion of the optical fiber 30a wound in the filament region 523 may be curved rapidly and curvature may be reduced. The optical signal transmission rate of the optical fiber 30a whose curvature is reduced due to bending of the optical fiber 30a may be degraded. The outer member 542 of the departure prevention portion 54 adjacent to the sleeve fixing portion 57 is formed with a mounting jaw 575 for receiving the end of the sleeve 31.

The mounting jaw 575 supports the sleeve 31 and prevents the sleeve 31 from moving in the downward direction so that the optical fiber 30a wrapped around the covering area 523 is not abruptly broken, It is possible to prevent problems that may occur due to breakage.

Although the sleeve fixing portion 57 is shown only on one side of the lower surface of the tray 52 in the drawing, the sleeve fixing portion 57 may be formed on both sides of the lower surface of the tray 52.

The tension line fixing portion 56 and the sleeve fixing portion 57 are formed on the tray 52. However, when the tension line fixing portion 56 and the sleeve fixing portion 57 are formed in a state in which the tray 52 is omitted, May be formed on the inner surface of the housing (51).

2 and 4, the adapter 60 is disposed on the upper surface of the tray 52, and the connector 32 is connected to one side. On the upper surface of the tray 52, engagement hooks 526 for fixing the adapter 60 are formed. When the tray 52 is omitted, the latching jaw 526 may be formed on the inner surface of the housing 51.

The branch cable 70 includes an optical fiber (not shown) and a connector 71. The optical fiber is covered with a cover and the connector 71 is coupled to the end. One connector 71 can be connected to the adapter 60 and the other connector (not shown) can be connected to a terminal device arranged in the living space. Since the connectors 32 and 71 are connected to each other in the adapter 60, the optical signal of the optical fiber 30a can be transmitted to the terminal device.

The structures of the optical fibers 30a and 30b, the connectors 32 and 71 and the adapter 60 described above can be applied to well-known technical fields of the optical communication field.

On the other hand, if the housing 511 hits the outer wall, it may be damaged by the impact and noise may be generated. The buffering portion 80 (see FIG. 2) having a buffering force can be wrapped around the housing 511. The buffer 80 may be made of sponge, rubber, or the like. Damage and noise can be prevented because the housing 511 does not directly contact the outer wall due to the buffering force of the buffer part 80. However, the buffer 80 may be omitted.

The operation of the optical signal transmission apparatus described above will be described with reference to Figs. 1 to 10 as a whole.

20 optical fibers 30a are arranged inside the first tube 10 when the optical signal transmission device 100 is installed in a building having 10 living spaces and 20 openings 11 are formed in the first tube 10. [ . The FTTH private terminal box 5 is disposed at each opening 11 position. The FTTH house terminal box 5 is connected to the tension line 40 by the tension line fixing part 56. [

The optical fiber 30a drawn out from the opening 11 and the optical fiber 30b connected to the connector 32 are fused to each other and the sleeve 31 surrounds the fused portion. The extracted optical fibers 30a are stored in the filament area 523 and fixed to the sleeve fixing part 57 of the sleeve 31. [ The optical fibers 30b are stored in the filament area 522 formed on the upper surface of the tray 52 through the hole 521 and the connector 32 is connected to the adapter 60. [

When the optical signal transmission apparatus 100 is placed on the outer wall of the building in such a state, each FTTH home terminal box 5 is disposed adjacent to each living space 1a, 1b, 1c on the outer wall.

When the branch cable 70 is to be connected to the FTTH home terminal box 5 in the living space, the lid 512 is opened to expose the adapter 60. The installation of the optical signal transmission apparatus 100 can be completed by connecting one connector 71 of the branch cable 70 to the other side of the adapter 60 and connecting the other connector to the terminal apparatus, To the terminal device in the space.
