It is made to pass.

광커넥터(202, SC 타입)와 광어댑터(201)사이의 결합상태는 커넥터이탈방지돌기(201b)와 커넥터걸림벽(202b)의 걸림작용에 의해 유지된다.The coupling state between the optical connector 202 (SC type) and the optical adapter 201 is maintained by the locking action of the connector separation preventing protrusion 201b and the connector locking wall 202b.

다음에 플러그단심페룰(183)이 광어댑터(201)의 어댑터페룰안내관(도시되지 않음)에 진입하도록 어댑터연결플러그(180)를 광어댑터(201)에 결합한다. 여기서 광어댑터(201)와 어댑터연결플러그(180)사이의 결합동작은 어댑터하우징안내홈(201a)에 커넥터안내돌기(202c)가 삽입되고 분배모듈이탈방지돌기(201b)가 어댑터연결편걸림벽(181a)을 넘어가도록 이루어진다.The adapter connection plug 180 is then coupled to the optical adapter 201 so that the plug single ferrule 183 enters the adapter ferrule guide tube (not shown) of the optical adapter 201. Here, the coupling operation between the optical adapter 201 and the adapter connection plug 180 is a connector guide protrusion 202c is inserted into the adapter housing guide groove 201a and the distribution module detachment prevention protrusion 201b is the adapter connection piece engaging wall 181a. )

In addition, according to the embodiment of the present invention as described above, the plug-type optical distribution module 10 detachably coupled to the optical adapter 201 and the branch plug detachably coupled to the optical distribution module 10 ( 80), the optical cable connection of the optical distribution device becomes very simple.

한편 전술한 실시예에서는 분배부광섬유(26)를 1(입력) X 2(출력) 형태로 구성하고 있으나, 1(입력) X 3(출력), 1(입력) X 4(출력) 등과 같이 다른 형태로 분배부광섬유(26)를 구성하여 본 발명을 실시할 수 있음은 물론이다.Meanwhile, in the above-described embodiment, the distribution optical fiber 26 is configured in the form of 1 (input) X 2 (output), but different from 1 (input) X 3 (output), 1 (input) X 4 (output), and the like. It is a matter of course that the present invention can be implemented by configuring the distribution optical fiber 26 in the form.

한편, 본 실시예에서 분배부복심페룰(23)은 복수개의 광섬유들이 내부에 포함되어 있다. 도 12a 및 도 12b는 본 발명의 일 실시예에 따른, 4개의 분배부광섬유(26-1 ~ 26-4)를 포함하는 분배부복심페룰(23)의 사시도 및 단면도이다. On the other hand, in the present embodiment, the distribution portion core ferrule 23 includes a plurality of optical fibers therein. 12A and 12B are a perspective view and a cross-sectional view of a distribution portion core ferrule 23 including four distribution portion optical fibers 26-1 to 26-4, according to an embodiment of the present invention.

도 12a 및 도 12b에 도시된 바와 같이, 분배부복심페룰(23)의 내부에는 4개의 4개의 분배부광섬유(26-1 ~ 26-4)가 장착될만한 원통형의 빈 공간이 형성되어 있다. 분배부복심페룰(23)에 형성된 원통형 빈 공간의 지름은 4개의 광케이블이 삽입되기 위해, 분배부광섬유의 지름의

Figure 112009059400562-pat00001
배 또는 그 이상이 된다. As shown in Figs. 12A and 12B, a hollow cylindrical space in which the four distribution optical fibers 26-1 to 26-4 can be mounted is formed in the interior of the distribution unit core ferrule 23. As shown in Figs. The diameter of the cylindrical hollow space formed in the distribution part core ferrule 23 is equal to the diameter of the distribution part optical fiber in order to insert four optical cables.
Figure 112009059400562-pat00001
It is double or more.

이와 같이, 분배부복심페룰(23)의 내부에 원통형의 빈 공간이 형성되면, 분배부복심페룰(23)은 분배부광섬유(26-1 ~ 26-4)가 내부에 쉽게 삽입된다. 또한, 분배부복심페룰(23)의 내부에 분배부광섬유(26-1 ~ 26-4)가 쉽게 고정되기 때문에, 4개의 분배부광섬유(26-1 ~ 26-4)가 삽입된 분배부복심페룰(23)을 더욱 쉽게 제조할 수 있게 된다. As described above, when the cylindrical hollow space is formed inside the distribution part core ferrule 23, the distribution part fiber optic fibers 26-1 to 26-4 are easily inserted therein. In addition, since the distribution optical fibers 26-1 to 26-4 are easily fixed to the inside of the distribution unit core ferrule 23, the distribution unit double cores into which the four distribution optical fibers 26-1 to 26-4 are inserted. The ferrule 23 can be manufactured more easily.

한편, 본 실시예에서는 분배부복심페룰(23)의 내부에 4개의 분배부광섬유(26-1 ~ 26-4)가 삽입된 것으로 설명하였으나, 이는 일 실시예에 불과하며, 분배부복심페룰(23)의 내부에 4개 이외에도 복수개의 분배부광섬유들이 삽입될 수도 있음은 물론이다. Meanwhile, in the present exemplary embodiment, four distribution optical fibers 26-1 to 26-4 are inserted into the distribution unit core ferrule 23, but this is only an example, and the distribution unit core ferrule ( 23, a plurality of distribution optical fibers may be inserted in addition to the four.

도 13a는 본 발명의 일 실시예에 따른, 나사 형태로 연결되는 어댑터연결편(50)과 스토핑관(30)을 도시한 도면이다. 그리고, 도 13b는 나사 형태로 연결된 상태의 어댑터연결편(50)과 스토핑관(30)을 포함하는 광분배모듈(10)의 결합단면도를 도시한 도면이다. Figure 13a is a view showing the adapter connection piece 50 and the stopper pipe 30 connected in the form of a screw, according to an embodiment of the present invention. And, Figure 13b is a view showing a coupling cross-sectional view of the optical distribution module 10 including the adapter connecting piece 50 and the stopper tube 30 in a screw form.

도 13a 및 도 13b에 도시된 바와 같이, 스토핑관(30)의 윗단 부분은 수나사부(1300)가 형성된다. 그리고, 어댑터연결편(50)의 하측 내부면에는 암나사부(1310)가 형성된다. 어댑터연결편(50)에 스토핑관(30)가 삽입될 때, 수나사부(1300)와 암나사부(1310)가 서로 맞물려 삽입된다. 따라서, 어댑터연결편(50)과 스토핑관(30)은 서로 단단하게 결합될 수 있게 된다. As shown in FIGS. 13A and 13B, the upper end portion of the stopper tube 30 is formed with a male thread part 1300. A female screw 1310 is formed on the lower inner surface of the adapter connecting piece 50. When the stopper tube 30 is inserted into the adapter connecting piece 50, the male screw portion 1300 and the female screw portion 1310 are engaged with each other. Therefore, the adapter connection piece 50 and the stopping pipe 30 can be tightly coupled to each other.

또한, 스토핑관(30) 내부에 장착되는 분배부복심페룰(23)은 플러그복심페룰(83)과 접촉된다. 이 때, 분배부복심페룰(23) 내부에 포함된 복수의 분배부광섬 유(26)는 플러그복심페룰(83)의 내부에 포함된 복수의 플러그광섬유(87)와 일치되도록 배치되어야 한다. 복수의 분배부광섬유(26)와 복수의 플러그광섬유(87)가 서로 일치되도록 배치되어야 광섬유들을 통해 광신호가 올바르게 전송되기 때문이다. In addition, the distribution part double core ferrule 23 mounted in the stopper tube 30 is in contact with the plug double core ferrule 83. At this time, the plurality of distribution part optical fiber 26 contained in the distribution part core ferrule 23 should be arranged to match the plurality of plug optical fibers 87 included in the plug part ferrule 83. This is because the plurality of distribution optical fibers 26 and the plurality of plug optical fibers 87 are disposed to coincide with each other so that an optical signal is correctly transmitted through the optical fibers.

이와 같이, 스토핑관(30)과 어댑터연결편(50)이 나사 형태로 결합되는 경우, 스토핑관(30)을 회전시킴으로써 어댑터연결편(50)에 스토핑관(30)을 결합시키게 된다. 따라서, 스토핑관(30)의 회전량을 조절함으로써, 복수의 분배부광섬유(26)와 복수의 플러그광섬유(87)가 서로 일치되도록 분배부복심페룰(23)의 위치를 조절할 수 있게 된다. As such, when the stopping pipe 30 and the adapter connecting piece 50 are coupled in a screw form, the stopper pipe 30 is coupled to the adapter connecting piece 50 by rotating the stopping pipe 30. Therefore, by adjusting the amount of rotation of the stopper tube 30, it is possible to adjust the position of the distribution part core ferrule 23 so that the plurality of distribution optical fibers 26 and the plug optical fibers 87 coincide with each other.

따라서, 스토핑관(30)과 어댑터연결편(50)이 나사 형태로 결합됨으로써, 매우 쉽고 안정적인 방법으로, 복수의 분배부광섬유(26)와 복수의 플러그광섬유(87)가 서로 일치되도록, 분배부복심페룰(23)의 위치를 조절할 수 있게 된다. Accordingly, the stopper tube 30 and the adapter connecting piece 50 are coupled in a screw form, so that the plurality of distribution part optical fibers 26 and the plurality of plug optical fibers 87 coincide with each other in a very easy and stable manner. The position of the cardiac ferrule 23 can be adjusted.

한편, 본 실시예에서는, 스토핑관(30)의 윗단 부분에 수나사부(1300)가 형성되고, 어댑터연결편(50)의 하측 내부면에 암나사부(1310)가 형성되는 것으로 설명하였으나, 그 반대로 형성될 수도 있음은 물론이다. 즉, 스토핑관(30)의 윗단 부분에 암나사부가 형성되고, 어댑터연결편(50)의 하측 내부면에 수나사부가 형성될 수도 있음은 물론이다. On the other hand, in the present embodiment, the male screw portion 1300 is formed on the upper end portion of the stopper pipe 30, it was described that the female screw portion 1310 is formed on the lower inner surface of the adapter connecting piece 50, on the contrary Of course, it may be formed. That is, the female screw portion is formed on the upper end portion of the stopper tube 30, the male screw portion may be formed on the lower inner surface of the adapter connecting piece 50, of course.
