도4는 플러그(100)와 리셉터클(200)이 체결되기 전의 형태이고, 도5는 체결된 상태를 보인 도로서, 플러그(100)의 정렬핀(124)이 리셉터클(200)의 정렬핀삽입공(228)에 삽입되고, 반대로 리셉터클(200)의 정렬핀(224)은 플러그(100)의 정렬핀삽입공(도시되지 않음)에 삽입되어 페룰(125)과 페룰(225)이 정렬됨과 아울러 전선소켓(126)에 전선플러그(226)가 삽입되면서 체결된다.
4 is a view before the plug 100 and the receptacle 200 are fastened, and FIG. 5 shows the fastened state, in which the alignment pin 124 of the plug 100 is inserted into the alignment pin of the receptacle 200. The alignment pin 224 of the receptacle 200 is inserted into the alignment pin insertion hole (not shown) of the plug 100 so that the ferrule 125 and the ferrule 225 are aligned and the wire The wire plug 226 is inserted into the socket 126 and fastened.

도6은 이러한 플러그(100)와 리셉터클(200)이 체결된 상태에서의 체결부위의 단면구조를 보인 도로서, 페룰(125)의 내측에서 제1광섬유(140)가 위치하고, 페룰(125)은 플러그(100)의 페룰삽입공(122)의 내에서 정렬되어 그 선단에 볼렌즈(127)가 일정거리 이격되어 장착된다.FIG. 6 is a cross-sectional view of the fastening portion in the state where the plug 100 and the receptacle 200 are fastened. The first optical fiber 140 is positioned inside the ferrule 125, and the ferrule 125 is The ball lens 127 is mounted in the ferrule insertion hole 122 of the plug 100 so as to be spaced apart from each other by a predetermined distance.

또한, 리셉터클(200)의 페룰삽입공(222)에도 제2광섬유(240)가 삽입된 페룰(225)이 정렬되어 그 선단에 볼렌즈(227)가 이격되어 위치함으로써 플러그(100)의 볼렌즈(127)와 서로 이격된 상태로 마주보게 체결되어 비접촉식으로 광신호의 전달이 이루어진다.In addition, the ferrule 225 into which the second optical fiber 240 is inserted is also arranged in the ferrule insertion hole 222 of the receptacle 200, and the ball lens 227 is spaced apart from the front end thereof so that the ball lens of the plug 100 is located. 127 is fastened to face each other while being spaced apart from each other and the optical signal is transmitted in a non-contact manner.

그런데, 페룰(125,225)에 의해 제1광섬유(140)와 제2광섬유(240)가 직선으로 정렬이 되었다할지라도 외부의 충격이나 온습도, 그리고 여러가지 조건에 의해 틀어져서 정렬오류가 발생하게 되어 광신호의 올바른 전송이 이루어지지 못하게 될 수 있다.However, even though the first optical fiber 140 and the second optical fiber 240 are aligned in a straight line by the ferrules 125 and 225, the alignment error occurs due to external shock, temperature and humidity, and various conditions. May not be able to transmit correctly.

이는 광신호 전송의 품질과 신뢰도에 크게 영향을 주는 것이므로, 이러한 정렬오류를 보상하기 위하여 제1광섬유(140)의 전방부를 선단으로 갈수록 확산되도록 열에 의해 확산시킨 확산부(141)를 형성함으로써 정렬 오류가 발생하더라도 광신호를 볼렌즈(127)로 올바르게 전달할 수 있도록 한다.Since this greatly affects the quality and reliability of the optical signal transmission, in order to compensate for such an alignment error, an alignment error is formed by forming a diffusion part 141 which is spread by heat to diffuse toward the front end of the first optical fiber 140. Even if it is possible to correctly transmit the optical signal to the ball lens 127.

물론, 제2광섬유(240)의 전방부도 확산부(241)를 형성함으로써 광 신호의 입사를 효율적으로 받아들일 수 있도록 한다.
Of course, the front portion of the second optical fiber 240 also forms the diffusion portion 241 so that the incident of the optical signal can be efficiently received.
