Description
본 발명은 광분배함의 광커넥터 고정장치에 관한 것으로서, 보다 상세하게는 걸림막대와 걸림홈을 형성시켜 광분배함(OFD;Optical Fiber Distribution)의 광분배기 어댑터에 광커넥터를 안정적으로 결합시키기 위한 광분배함의 광커넥터 고정장치에 관한 것이다.The present invention relates to an optical connector fixing device of an optical distribution box, and more particularly, to form an engaging bar and a locking groove to optically couple an optical connector to an optical distributor adapter of an optical fiber distribution (OFD). An optical connector fixing device for a distribution box.
일반적으로 광섬유는 굴절율이 높은 코어와 굴절율이 낮은 크래드로 구성되고, 반사 또는 굴절에 의해 광에너지를 전파하는 부전도성의 도파관으로 사용된다.또 광섬유에 있어서 광신호는 코어와 크래드의 경계면에서 전반사를 반복하면서 도파되고, 크래드의 외부를 둘러싸고 있는 코팅층은 습기나 마모로부터 광섬유를 보호하는 역할을 담당함과 동시에 취급을 용이하게 한다.In general, an optical fiber is composed of a core having a high refractive index and a clad with a low refractive index, and used as a non-conductive waveguide for propagating optical energy by reflection or refraction. In optical fibers, an optical signal is used at the interface between the core and the clad. The coating layer, which is guided by repeating the total reflection and surrounds the exterior of the clad, serves to protect the optical fiber from moisture and abrasion while facilitating handling.
상기와 같은 광섬유는 접속이 어렵고, 너무 가늘기 때문에 절단되었을 때에 수리가 어려우며, 외부 충격에 약한 문제점이 있다. 또 광섬유는 제조한계, 기기와의 연결필요성 등 때문에 광섬유의 불연속면이 반드시 존재하게 되며, 이러한 불연속면은 신호전달을 위해 반드시 연결장치부가 필요하다.Such an optical fiber is difficult to connect and difficult to repair when cut because it is too thin, and has a weak problem in external impact. In addition, the optical fiber has a discontinuous surface of the optical fiber due to manufacturing limitations and the necessity of connection with the device, and such discontinuous surface must have a connecting device for signal transmission.
상기 연결장치부로서는 광커넥터가 사용되며, 광섬유는 광도파로가 매우 작아 정밀하게 연결되지 않으면 신호의 감쇄로 큰 증폭이 필요하거나 광원에의 불안정을 야기시킬 우려가 높다.An optical connector is used as the connection unit, and an optical fiber has a high optical waveguide, and thus, if it is not precisely connected, a large amplification is required due to attenuation of a signal or there is a high possibility of causing instability to the light source.
상기 광커넥터는 삽입손실을 감소시킬 수 있도록 초정밀 생산기술에 기반을 둔 실린더 모양으로 형성된 세라믹 페룰과 슬리브와의 결합형, 초정밀 볼베어링과 원추형 페룰과의 결합형 등이 있고, 반사손실 특성을 향상시키기 위하여 광섬유를 포함한 페룰 단면을 연마하는 형과 굴절률 정합물질을 사용하는 형이 있다.The optical connector includes a combination of a ceramic ferrule and a sleeve formed in a cylindrical shape based on a high precision production technology and a combination of a high precision ball bearing and a conical ferrule in order to reduce insertion loss, and to improve reflection loss characteristics. For this purpose, there are a type of polishing a ferrule cross section including an optical fiber and a type using a refractive index matching material.
종래 광커넥터는 결합유지를 위하여 스프링을 사용하고 있으며, 푸쉬풀(push-pull)구조를 채택하고, 광섬유와의 결선을 위하여 결선도구를 사용한다. 상기 푸쉬풀구조는 일반적으로 사출성형에 의하여 제조되고, 결합유지력을 형성시키기 위하여 코일스프링을 사용하고 있으며, 광섬유와 광커넥터 결합은 결선용 도구를 반드시 필요로 한다. 또 플러그나 광어댑터에 고유하게 설계된 잠금기구를 가지고 있는 등 특수한 기능들을 보유한 다른 구조를 채택하는 경우도 있다.Conventional optical connector uses a spring to maintain the coupling, adopts a push-pull structure, and uses a wiring tool for the connection with the optical fiber. The push pull structure is generally manufactured by injection molding, and uses coil springs to form a bond holding force, and optical fiber and optical connector coupling necessarily requires a connection tool. Others may have other structures with special features, such as locking mechanisms unique to plugs or optical adapters.
상기 광커넥터는 광분배반이나 광분배함 등의 성단함에 연결시켜야 하고, 광분배함은 광케이블과 광전송장치 및 광중계장치 등을 상호연결 및 광케이블의 광섬유심선을 분배하기 위하여 전화국에 설치하여 운용하는 장치이다.The optical connector should be connected to a star cluster such as an optical distribution panel or an optical distribution box, and an optical distribution box is an apparatus for installing and operating an optical cable, an optical transmission device, and an optical relay device in a telephone station for interconnecting and distributing optical fiber core lines of the optical cable. to be.
종래 광분배함의 중간부위에는 다수의 분배기가 횡으로 배열되고, 상기 각 분배기에는 상하로 광어댑터가 설치된다. 상기 광어댑터에는 광섬유가 연결된 광커넥터가 장착되고, 광섬유는 분배기 단위로 코드가이드에 묶여진다.A plurality of distributors are arranged horizontally in the middle portion of the conventional light distribution box, and each of the distributors is provided with an optical adapter up and down. The optical adapter is equipped with an optical connector to which the optical fiber is connected, and the optical fiber is bundled to the cord guide in a divider unit.
그런데 종래에 있어서 광커넥터를 광어댑터에 장착하거나 광어댑터로부터 탈거하는 경우에는 둘 사이의 고정장치가 없어, 이웃하는 다른 광커넥터를 건드림으로 인하여 외부 충격에 약한 광섬유가 손상되어 고장이 발생할 가능성이 높고, 또한 원하지 않는 광커넥터를 탈착할 가능성이 높다.However, conventionally, when the optical connector is mounted on the optical adapter or removed from the optical adapter, there is no fixing device between the two, and the optical fiber, which is weak to external impact, may be damaged by touching another neighboring optical connector, which may cause a failure. It is high and also likely to detach the unwanted optical connector.
본 발명의 목적은 상기와 같은 문제점을 해결하기 위한 것으로서, 광커넥터와 광어댑터가 외부 충격에 의하여 쉽게 분리되지 않도록 결합막대와 결합홈을 형성한 광분배함의 광커넥터 고정장치를 제공하기 위한 것이다.SUMMARY OF THE INVENTION An object of the present invention is to provide an optical connector fixing device of an optical distribution box formed with a coupling rod and a coupling groove so that the optical connector and the optical adapter are not easily separated by an external impact.
