Description
본 발명은 광전복합 커넥터에 관한 것으로, 더 상세하게는 광섬유와 전원선을 동시에 접속할 수 있도록 하는 광전복합 커넥터에 관한 것이다.The present invention relates to a photoelectric composite connector, and more particularly, to a photoelectric composite connector capable of simultaneously connecting an optical fiber and a power line.
일반적으로 광통신 중계기 등 광통신설비에 사용되는 광케이블은 유리 또는 플라스틱 재질로 만들어져 가볍고, 높은 전송 속도를 갖는 이점 때문에 고속 데이터 송수신과 높은 신뢰도를 필요로 하는 데이터 전송분야에 사용되고 있다. In general, optical cables used in optical communication facilities such as optical communication repeaters are made of glass or plastic material, and are used in data transmission fields that require high-speed data transmission and high reliability because of light weight and high transmission speed.
종래에는 광통신설비에 광신호와 전원을 공급하기 위하여 광케이블과 별도의 전원케이블을 연결할 필요가 있었으며, 이를 위하여 광커넥터와 전원커넥터를 별도로 사용하였다. Conventionally, it was necessary to connect an optical cable and a separate power cable to supply an optical signal and power to an optical communication facility, and for this purpose, an optical connector and a power connector were used separately.
이처럼 광커넥터와 전원커넥터를 별도로 사용함에 따라 설치작업이 어렵고, 설치비용 또한 많이 소요되는 문제점이 있었다.As such, since the optical connector and the power connector are separately used, the installation work is difficult, and the installation cost is also high.
이러한 문제점을 감안하여 단일한 케이블로 광과 전원을 동시에 공급할 수 있는 광전복합케이블이 개발되었으며, 이러한 광전복합케이블을 연결하기 위한 광전복합 커넥터가 개발되었다. In view of these problems, a photoelectric composite cable capable of simultaneously supplying light and power with a single cable has been developed, and a photoelectric composite connector for connecting such a photoelectric composite cable has been developed.
등록특허 10-1017085호(2011년 2월 16일 등록, 광전 복합 커넥터)에는 광과 전원 소켓을 각각 제공하는 소켓부와, 광고 전원 플러그를 각각 제공하는 플러그부를 마련하고, 체결 수단으로 소켓부와 플러그부를 체결하여 이탈을 방지하며, 플러그부의 선단이 소켓부의 오링을 가압하여 기밀을 유지하는 구성이 기재되어 있다.Patent No. 10-1017085 (Registered Feb. 16, 2011, Optoelectronic Composite Connector) provides a socket portion for providing light and a power socket, and a plug portion for providing an advertisement power plug, respectively, and the socket portion as a fastening means. The configuration is described in which the plug portion is fastened to prevent separation, and the tip of the plug portion presses the O-ring of the socket portion to maintain airtightness.
상기 체결 수단으로는 결합공에 결합되는 볼트를 사용하고 있으나, 이러한 다수의 볼트를 체결하는데 시간이 필요할 뿐만 아니라 모든 볼트를 균일한 정도로 체결하지 않으면 광신호의 전달 오류가 발생할 수 있으며, 이물이 유입될 수 있는 문제점이 있었다.The fastening means uses a bolt coupled to the coupling hole, but not only requires time to fasten the plurality of bolts, but if all bolts are not fastened to a uniform degree, a transmission error of an optical signal may occur, and foreign substances may flow in. There was a problem that could be.
또한 체결 수단이 풀리거나 사용중 손상되는 경우에 정확한 광신호의 전달을 보장할 수 없으며, 이물과 습기의 유입을 방지하기 위한 수단이 플러그부와 소켓부의 연결부에만 적용되어 있기 때문에 양단의 광전복합케이블 측에서 습기가 유입될 수 있는 문제점이 있었다. In addition, when the fastening means is loosened or damaged during use, the accurate optical signal transmission cannot be guaranteed, and the means for preventing the inflow of foreign objects and moisture are applied only at the connection part of the plug and socket parts, so that both ends of the photoelectric cable There was a problem that can be introduced into the moisture.
