Description

피그테일 현장조립형 광커넥터{OPTICAL CONNECTOR FOR ASSEMBLING IN THE FIELD}Pigtail Field-mounted Optical Connector {OPTICAL CONNECTOR FOR ASSEMBLING IN THE FIELD}

본 발명은 광커넥터에 관한 것으로서, 더욱 상세하게는 작업현장에서 접속에 따른 광손실이 없이 조립할 수 있는 현장조립형 광커넥터에 관한 것이다.The present invention relates to an optical connector, and more particularly, to a field assembly type optical connector that can be assembled without the optical loss of the connection in the workplace.

일반적으로 광커넥터는 정해진 파라메타에 맞게 절단한 광섬유를 공장에서 작업자가 광중심축이 맞도록 광섬유의 코어가 삽입된 페룰을 정렬하여 에폭시 본딩 및 단면 연마공정을 거쳐서 광손실을 최소화하고, 양끝단에 광커넉터를 부착하여 패치코드라는 완제품 형태를 광선로 포설에 사용되어 왔다.In general, the optical connector aligns the ferrule in which the core of the optical fiber is inserted so that the operator can fit the optical center in the factory to minimize the optical loss through the epoxy bonding and the end face polishing process. By attaching an optical connector, a finished product called a patch cord has been used for laying a fiber.

일반적인 패치코드는 정해진 파라메타에 따라 일정 길이를 가진 완제품의 형태로 공장에서 제조되기 때문에, 광전송장비와 광섬유케이블 상호간에 접속 및 분리를 필요로 하는 광분배반, 광단자함, 광 중간 절체함에서 광케이블간 연결 또는 광분배반과 광 전송장치간, 광 전송장치 상호간의 연결에 있어 길이의 한계에 직면하였다.Since general patch cords are manufactured at the factory in the form of finished products having a certain length according to the specified parameters, the connection between optical cables in optical distribution boards, optical terminal boxes, and optical intermediate switching boxes that requires connection and disconnection between optical transmission equipment and optical fiber cables. Or, there is a limit in length in the connection between the optical distribution panel and the optical transmission device and the optical transmission device.

이에, 패치코드의 양측에 마련된 광커넥터를 조립형으로 개조하여 현장에서 간편하게 조립할 수 있도록 함으로써, 원하는 길이의 패치코드를 얻을 수 있도록 하였다.Thus, by converting the optical connectors provided on both sides of the patch cord into an assembly type to be easily assembled in the field, it was possible to obtain a patch cord of the desired length.

*조립형으로 개조된 광커넥터의 종래기술로는 대한민국 등록특허공보 제10-0507543호에 개시되어 있다.* The conventional technology of the optical connector modified to the assembly type is disclosed in Korean Patent Publication No. 10-0507543.

종래기술에 따른 광커넥터는 하우징과, 하우징내에 삽입되는 프레임과, 프레임내에 탄성적으로 유동되게 마련되는 페룰과, 페룰에 끼워지는 코어정렬부재와, 페룰의 일부를 감싸며 프레임에 삽입 고정되는 고정부재와, 고정부재에 맞물려 부착고정되는 광섬유 연결부재와, 코어가 페룰에 끼워지도록 광섬유 연결부재를 관통하여 끼워지는 광섬유를 클립형태로 맞물려 고정하기 위해 광섬유 연결부재를 조이는 조임부재가 포함되어 있다.The optical connector according to the prior art includes a housing, a frame inserted into the housing, a ferrule provided to elastically flow in the frame, a core alignment member fitted to the ferrule, and a fixing member which is inserted into and fixed to the frame while surrounding a part of the ferrule. And a fastening member for tightening the optical fiber connecting member for engaging and fixing the optical fiber connecting member which is fixedly engaged with the fixing member, and the optical fiber inserted through the optical fiber connecting member so as to be fitted into the ferrule in the form of a clip.

이와 같이 구성된 종래기술의 광커넥터는 프레임, 페룰, 고정부재, 광섬유 연결부재, 조임부재가 미리 조립된 상태에서 광섬유를 광섬유 연결부재에 삽입하여 삽입된 광섬유의 코어와 페룰에 미리 삽입된 코어와 접속되게 한다. 그리고, 조임부재에 의해 광섬유 연결부재를 가압하여 삽입된 광섬유를 고정시키게 된다. 그런 다음 하우징과 보호부츠를 조립하여 작업이 완료된다.The optical connector of the prior art configured as described above is connected to the core of the inserted optical fiber and the core pre-inserted in the ferrule by inserting the optical fiber into the optical fiber connecting member in a state where the frame, the ferrule, the fixing member, the optical fiber connecting member, and the fastening member are assembled in advance. To be. Then, the optical fiber connecting member is pressed by the fastening member to fix the inserted optical fiber. The assembly is then completed by assembling the housing and protective boots.

*그러나, 종래기술의 광커넥터는 광섬유 연결부재에 인입된 광섬유를 고정하기 위해 광섬유 연결부재의 외면을 클립형태로 가압하는 조임부재에 의해 이루어지기 때문에, 조임부재의 가압력이 광섬유 연결부재를 통해 광섬유에 전달되기 위해서는 광섬유 연결부재는 유연한 성질을 갖는 재질이 사용된다.However, since the optical connector of the prior art is made by a fastening member for pressing the outer surface of the optical fiber connecting member in the form of a clip to fix the optical fiber introduced into the optical fiber connecting member, the pressing force of the fastening member is the optical fiber through the optical fiber connecting member. In order to be transmitted to the optical fiber connecting member is used a material having a flexible property.

이에 따라, 광섬유 연결부재는 횡방향 외력에 대해 쉽게 굽어지게 된다. 이는 광섬유 연결부재내에 삽입된 광섬유도 굽어지게 되므로, 접속시 광손실이 증대되어 접속불량이 발생되는 문제점이 있었다.Accordingly, the optical fiber connecting member is easily bent against the lateral external force. This is because the optical fiber inserted into the optical fiber connection member is also bent, there is a problem that the connection loss occurs due to the increased optical loss.

또한, 광섬유 연결부재내에 삽입된 광섬유의 고정을 클립형태의 가압부재가 갖는 탄성력에만 의존하게 되므로 광섬유를 견고하게 고정하기에는 한계가 있었다.In addition, since the fixing of the optical fiber inserted into the optical fiber connection member depends only on the elastic force of the pressing member in the form of a clip, there is a limit to firmly fixing the optical fiber.

또 한편으로는, 광섬유 연결부재에 인입된 광섬유가 별도의 안내수단 없이 끼워지기 때문에 광섬유 인입작업시 많은 흔들림이 발생되어 광섬유의 코어를 코어정렬부재의 코어삽입홀을 통해 페룰내에 정확하게 끼우기가 힘들었다. 특히, 대략 125㎛의 직경을 갖는 코어가 끼워지도록 코어의 직경에 상응하는 직경을 가진 코어삽입홀에 코어를 정확하게 끼워넣는 작업이 매우 어려웠다.On the other hand, since the optical fiber introduced into the optical fiber connection member is inserted without a separate guide means, a lot of shaking occurs during the optical fiber insertion operation, it is difficult to accurately fit the core of the optical fiber in the ferrule through the core insertion hole of the core alignment member. In particular, it was very difficult to accurately fit the core into a core insertion hole having a diameter corresponding to the diameter of the core so that the core having a diameter of approximately 125 μm was fitted.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 광커넥터에 인입된 광섬유를 견고히 고정할 수가 있고, 있으며, 구조가 상대적으로 간단한 현장조립형 광커넥터에 관한 것이다.
