본 발명은 광케이블 종단에 설치하는 인장부재 지지장치에 관한 것으로서, 더욱 상세하게는, 광케이블의 인장부재를 광케이블 종단에 설치되어 있는 지지장치를 이용하여 고정함으로써, 광케이블 설치시 발생하는 인장력에 의해서 광섬유가 손상되는 것을 방지하는 광케이블 종단에 설치하는 인장부재 지지장치에 관한 것이다.The present invention relates to a tension member support device to be installed at the end of the optical cable, and more particularly, by fixing the tension member of the optical cable using a support device provided at the end of the optical cable, the optical fiber is The present invention relates to a tension member support device installed at an end of an optical cable to prevent damage.

일반적으로 광통신은 빛을 전송하여 정보를 교환할 수 있도록 하는 것으로, 유리섬유로 된 광섬유를 매개체로 하여 사용자가 원하는 정보를 전송할 수 있다. 이러한 광케이블은 설치장소에 따라 옥외에 포설되는 옥외용 광케이블과, 옥내의 단자함으로부터 아울렛이나 단말기까지 연결되는 옥내용 광케이블 및 옥외의 접속함으로부터 옥내의 단자함으로 인입되는 인입용 광케이블로 크게 구분된다.In general, optical communication is to transmit information by transmitting light, and may transmit information desired by a user through an optical fiber made of glass fiber. Such optical cables are largely classified into outdoor optical cables installed outdoors, indoor optical cables connected from indoor terminal boxes to outlets or terminals, and incoming optical cables introduced into outdoor terminal boxes from outdoor junction boxes.

상기 옥내용 광케이블은 각 가입자 내부의 천장, 벽, 바닥 등에 설치 운용되 는 것으로, 국내외적으로 LAN(Local Area Network)의 보급 확산과 각종 광통신 서비스에 관련된 가입자 회로망의 보급추세에 따라 그 수요가 점차 증가하고 있다.The indoor optical cable is installed and operated in the ceiling, wall, floor, etc. inside each subscriber, and the demand is gradually increased in accordance with the spread of LAN (Local Area Network) and subscriber network related to various optical communication services at home and abroad. It is increasing.

도 1은 옥내용 광케이블의 일예를 보여주는 개략적인 사시도이다. 도시된 바와 같이, 옥내용 광케이블(101)은 PCV코팅된 다수의 광섬유(3)와, 이 다수의 광섬유(3)를 감싸는 외피(7)와, 광섬유(3)와 외피(7)사이에 그 길이방향으로 내장되어 있는 아라미드사(Aramid Yarn)(5)로 구성되어 있다. 이 때, 아라미드사(5)는 광케이블(101) 설치시 필연적으로 발생하는 인장력에 의해서 광섬유(3)가 손상되는 것을 방지하기 위한 인장선이다. 그리고, 외피(7)는 외력으로부터 광섬유(3)를 보호하기 위한 완충부재이다.1 is a schematic perspective view showing an example of an indoor optical cable. As shown, the indoor optical cable 101 includes a plurality of PCV-coated optical fibers 3, a shell 7 surrounding the plurality of optical fibers 3, and a space between the optical fibers 3 and the shell 7. It consists of an aramid yarn 5 built in the longitudinal direction. At this time, the aramid yarn 5 is a tensile line for preventing the optical fiber 3 from being damaged by the tensile force inevitably generated when the optical cable 101 is installed. The outer shell 7 is a buffer member for protecting the optical fiber 3 from an external force.

한편, 이러한 옥내용 광케이블(101)은 옥내 단자함(광분배함:FDF)이나 광아울렛에서 접속단자와 접속할 수 있도록 그 내부의 광섬유(3)가 단심 광섬유로 분기된다. 이러한 분기점에서 옥내용 광케이블(101)의 외피(7)는 제거되고 광섬유(3)와 아라미드사(5)는 외부로 노출된다. 광섬유(3)의 선단은 도시되지 않은 커넥터나 융착을 통해서 접속단자 등에 고정된다. 이때, 도 1에서 보는 바와 같이, 옥내용 광케이블(101)의 종단에는 짧게 잘라진 아라미드사(5)를 감싸도록 열수축튜브(9)가 외피(7)의 외주면을 감싸도록 설치된다. 이 때, 열수축튜브(9)로 감싸여진 옥내용 광케이블(101)은 케이블 타이(Cable tie)(4) 등을 이용하여 옥내 단자함이나 아울렛에 형성되어 있는 결합홈이나 고정리브(6)에 고정되게 된다.On the other hand, in the indoor optical cable 101, the optical fiber 3 therein branches into a single-core optical fiber so that the indoor optical box 101 can be connected to a connection terminal in an indoor terminal box (optical distribution box: FDF) or an optical outlet. At this fork, the shell 7 of the indoor optical cable 101 is removed and the optical fiber 3 and the aramid yarn 5 are exposed to the outside. The tip of the optical fiber 3 is fixed to a connection terminal or the like through a connector or fusion not shown. At this time, as shown in Figure 1, at the end of the indoor optical cable 101, the heat shrink tube 9 is installed to surround the outer peripheral surface of the shell 7 so as to surround the short cut aramid yarn (5). At this time, the indoor optical cable 101 wrapped with the heat shrink tube 9 is fixed to the coupling groove or the fixed rib 6 formed in the indoor terminal box or outlet using a cable tie (4) or the like. do.

이와 같이, 종래의 옥내용 광케이블(101)은 케이블 타이(4)가 외피(7)의 외주면에 결합될 뿐이고, 아라미드사(5)와는 결합되지 않는 구조이다. 또한, 옥내용 광케이블(101)의 종단에 설치되는 열수축튜브(9)는 이물질 등의 유입을 막을 수 있을 뿐이고, 아라미드사(5)를 고정하는 역할은 하지 못하였다. As described above, the conventional indoor optical cable 101 has a structure in which the cable tie 4 is only coupled to the outer circumferential surface of the shell 7 and is not bonded to the aramid yarn 5. In addition, the heat shrink tube 9 provided at the end of the indoor optical cable 101 can only prevent the inflow of foreign substances and the like, and does not serve to fix the aramid yarn 5.

따라서, 옥내용 광케이블(101)을 설치할 때, 작업자가 광케이블(1)을 잡아당기면 케이블 타이(4)에 의해 고정리브(6)에 고정된 외피(7)는 인장되지 않고 그 내부에 있는 아라미드사(5)가 인장되면서 광섬유(3)도 함께 당겨지게 되어 광섬유(3)가 손상되는 문제점이 있다. Therefore, when installing the indoor optical cable 101, when the operator pulls the optical cable 1, the outer shell 7 fixed to the fixed rib 6 by the cable tie 4 is not tensioned and the aramid yarn inside it. There is a problem that the optical fiber (3) is also pulled together as the tension (5) is pulled together to damage the optical fiber (3).

이러한 문제점을 해결하기 위해서, 종래의 옥외용 또는 인입용 광케이블의 종단에는 인장선을 고정하기 위한 인장선 고정장치가 별도로 구비되어 있다. 일 예로, 도 2에 도시된 바와 같이, 특허등록 제10-385561호 '광성단 케이블의 인장선 고정장치'에는 광케이블(11)의 종단에 다수의 광섬유(13)를 감싸는 하우징(12)을 설치하고, 이 하우징(12)의 선단에는 광케이블(11)의 중심에 내재된 인장선(15)을 고정하기 위한 인장선 고정장치(14)가 구비되어 있다. In order to solve this problem, the tension line fixing device for fixing the tension line is provided separately at the end of the conventional outdoor or incoming optical cable. For example, as shown in Figure 2, Patent Registration No. 10-385561 'tension line fixing device of the optical end cable' is installed a housing 12 surrounding the plurality of optical fibers 13 at the end of the optical cable 11 At the distal end of the housing 12, a tension line fixing device 14 for fixing the tension line 15 embedded in the center of the optical cable 11 is provided.

이에, 인장선(15)을 고정하기 위한 인장선 고정장치(14)를 하우징(12)에 설치하고 이 하우징(12)을 옥내의 단자함 등에 고정함으로써, 광케이블(11)을 포설할 때 발생하는 인장력이 인장선(15)으로 전달되도록 함으로써 광섬유(13)가 손상되는 것을 방지할 수 있다. Accordingly, by installing a tension wire fixing device 14 for fixing the tension wire 15 to the housing 12 and fixing the housing 12 to an indoor terminal box or the like, the tensile force generated when the optical cable 11 is laid. The optical fiber 13 can be prevented from being damaged by being transmitted to the tension line 15.

그러나, 이러한 종래의 인입용 광케이블 적용된 인장선 고정장치는 중심 인장선을 고정하기 위한 것으로 광섬유를 둘러싸고 있는 아라미드사를 고정하기에는 적합하지 않은 구조이다. 또한, 종래의 인장선 고정장치는 광케이블의 종단을 감싸면서 그 선단으로 돌출된 하우징을 필요로 하기 때문에 크기가 크고 광섬유의 분기 작업이 복잡하는 등 옥내용 광케이블에 사용하기에는 적당하지 않은 등 여러 문제점을 가지고 있었다.However, the conventional tension line fixing device applied to the incoming optical cable is for fixing the center tension line is not suitable for fixing the aramid yarn surrounding the optical fiber. In addition, the conventional tension line fixing device wraps the end of the optical cable and requires a housing protruding to the end thereof, so it is not suitable for indoor optical cables such as large size and complicated branching operation of the optical fiber. I had.

따라서, 본 발명의 목적은, 광섬유를 보호하고 있는 인장부재를 지지함으로써 광케이블 설치시 발생하는 인장력이 광섬유로 전달되는 것을 방지할 수 있고, 광섬유의 분기작업이 단순하여 작업성이 향상되는 인장부재 지지장치를 제공하는 것이다. Therefore, an object of the present invention, by supporting the tension member for protecting the optical fiber can prevent the tensile force generated during the installation of the optical cable to be transmitted to the optical fiber, supporting the tension member to improve the workability is simple branching operation of the optical fiber To provide a device.

상기 목적은, 본 발명에 따라, 다수의 광섬유와, 상기 다수의 광섬유를 감싸는 외피와, 상기 광섬유와 외피 사이에 길이방향으로 마련되어 상기 광섬유를 보호하는 인장부재를 포함하는 광케이블에 있어서, 상기 다수의 광섬유와 상기 인장부재가 외부로 노출되어 있는 상기 광케이블의 종단에 삽입되어 상기 외피의 외주면에 결합되는 결합부재와; 단부영역이 절곡되어 상기 결합부재의 외주면에 위치하는 상기 인장부재를 지지하도록 상기 결합부재의 외주면에 가압되는 가압부재에 의해 달성된다.

여기서, 상기 결합부재는 원통형의 결합본체와; 상기 결합본체의 일단부로부터 연장 형성되며 길이방향을 따라 절개된 절개홈에 의해서 형성된 복수의 탄성편과, 상기 탄성편의 선단에 돌출 형성되어 상기 가압부재의 내측면에 걸리는 걸림돌기를 갖는 후크부를 포함하는 것이 바람직하다. Here, the coupling member and the coupling body of the cylindrical; A plurality of elastic pieces extending from one end of the coupling body and formed by a cutting groove cut along the longitudinal direction, and a hook portion protruding from the front end of the elastic piece and having a locking projection caught on the inner surface of the pressing member.

It is preferable that the end of the coupling body connected to the hook portion is formed with a stepping step so as to stop the flow of the tension member when the front end of the pressing member is forcibly fitted.

가압부재(170)는 결합본체(151)에 억지 끼움되는 원통형의 가압본체(171)와, 후크부(155)의 걸림돌기(156)가 걸리도록 가압본체(171)의 내주면에 형성된 단턱부(174)를 포함하여 구성된다. 따라서, 본 제2실시예에 따르면, 가압부재(170)는 탄성편(154)의 탄성 작용으로 보다 용이하게 결합부재(150)와 결합하고, 일단 결합된 가압부재(170)는 걸림돌기(156)와 단턱부(174)의 결합으로 이탈되지 않게 된다.The pressing member 170 has a cylindrical pressing body 171 forcibly fitted to the coupling body 151 and a stepped portion formed on the inner circumferential surface of the pressing body 171 so as to catch the locking protrusion 156 of the hook portion 155. 174). Therefore, according to the second embodiment, the pressing member 170 is more easily coupled with the coupling member 150 by the elastic action of the elastic piece 154, and the pressing member 170 once coupled is the locking projection 156 ) And the stepped portion 174 are not separated.

이하에서는, 도 5 및 도 6을 참조하여 본 발명에 따른 인장부재 지지장치(130)의 설치 및 작용을 살펴본다.Hereinafter, with reference to Figures 5 and 6 looks at the installation and operation of the tension member support device 130 according to the present invention.

As shown in FIGS. 5 and 6, the ends of the optical cable 1 have the outer shell 7 removed to expose a plurality of optical fibers 3 and tension members 5. Then, the coupling member 150 is forcibly inserted into the end of the optical cable 1 to which the plurality of optical fibers 3 and the tension members 5 are exposed, and are installed on the outer circumferential surface of the shell 7. At this time, the outer shell 7 is coupled to the coupling member 150 relatively easily because of excellent compressibility.

이어, 노출된 다수의 광섬유(3)를 관통시켜 결합부재(150)와 대응하도록 가압부재(170)를 설치한다. 그 후, 인장부재(5)를 후방으로 180ㅀ구부려서 결합부재(150)의 유동저지단(158)의 외주면에 위치하도록 한다. 이와 같이, 인장부재(5)를 유동저지단(158)에 위치시킨 상태에서 가압부재(170)를 결합부재(150)쪽으로 밀어넣어 결합한다. Subsequently, the pressure member 170 is installed to penetrate the exposed plurality of optical fibers 3 to correspond to the coupling member 150. Thereafter, the tension member 5 is bent backward by 180 ° so as to be positioned on the outer circumferential surface of the flow stop end 158 of the coupling member 150. As such, the pressing member 170 is pushed toward the coupling member 150 in the state where the tension member 5 is positioned at the flow stop end 158 to be coupled.

이 때, 결합부재(150)의 탄성편(154)은 안쪽으로 가압 변위되어 가압부재 (170)가 용이하게 결합되도록 하고, 탄성편(154)의 걸림돌기(156)는 가압부재(170)의 내주면에 형성된 단턱부(174)와 결합되어 결합부재(150)가 이탈되는 것을 방지한다.
