Description

다심 일괄형 광커넥터{MT optical connector}Multi-core bulk optical connector {MT optical connector}

본 발명은 광섬유 결합소자에 관한 것으로, 특히 신호원, 검파기 혹은 광섬유와 광섬유를 결합하는 수동소자로 반복결합이 손쉽게 이루어지는 광커넥터에 관한 것이다.The present invention relates to an optical fiber coupling element, and more particularly, to an optical connector in which a repetitive coupling is easily performed by a signal source, a detector, or a passive element combining an optical fiber and an optical fiber.

광커넥터는 커넥터당 접속할 수 있는 광섬유의 수에 따라 ST, SC, FC, EC와 같은 단심 광커넥터와 MT, FDDI와 같은 다심 광커넥터로 구분된다. 그 중 다심 일괄형 광커넥터는 푸쉬-풀 결합방식으로 전송장치용 및 케이블용 구분없이 다중모드 광섬유에 대응하기 위하여 사용한다. 다심 일괄형 광커넥터는 다심 광섬유를 일체형으로 연결하여 케이블 접속구조를 어떻게 용이한 구조를 제작하여 케이블 접속시간 단축 및 설치 방법의 간소화 추진 및 평균접속손실 최저화(0.35db기준)를 위한 구조 형상이 중요하다.Optical connectors are classified into single-core optical connectors such as ST, SC, FC and EC and multi-core optical connectors such as MT and FDDI, depending on the number of optical fibers that can be connected per connector. Among them, the multi-core batch optical connector is a push-pull coupling method, which is used to cope with the multimode optical fiber without the distinction for the transmission device and the cable. Multi-core packaged optical connector has a structure shape for shortening the cable connection time, simplifying the installation method, and minimizing the average connection loss (0.35db standard) by making the structure of the cable connection structure easy by connecting the multi-core optical fiber as an integrated type. It is important.

이러한 사항을 고려해볼 때 융착접속기술에 의한 기계적 슬라이스 기술/현재 적용되고 있는 다심 일괄형 커넥터의 접속구조 방식의 어려움 및 접속시간단축 애로사항으로 인한 접속부의 구조방식의 한계가 있다.Considering these matters, there is a limitation of the connection method due to the difficulty of the connection structure method of the mechanical slice technology by the fusion splicing technology / currently applied multi-core packaged connector and the shortening of the connection time.

도 1은 종래의 다심 일괄형 광커넥터를 도시한 것으로, 광섬유(110), 부트(120), 몸체부(130) 및 가이드 핀(140)으로 이루어진다.FIG. 1 illustrates a conventional multi-core packaged optical connector, and includes an optical fiber 110, a boot 120, a body 130, and a guide pin 140.

광섬유(110)는 정보를 전송하는 수단으로 리본광섬유가 사용된다. 부트(120)는 외부에 노출된 광섬유(110)의 휨이나 비틀림을 방지하기 위한 것이다. 몸체부(130)는 부트(120)를 고정시키는 몸체이다. 가이드 핀(140)은 몸체부(130)를 결합시키는 수단이다.Ribbon optical fiber is used for the optical fiber 110 as a means for transmitting information. Boot 120 is to prevent the bending or twisting of the optical fiber 110 exposed to the outside. Body 130 is a body for fixing the boot (120). The guide pin 140 is a means for coupling the body portion 130.

이러한 다심 일괄형 광커넥터는 외부진동 및 충격으로 인한 가이드 핀(pin)의 크랙 및 빠짐현상이 발생되어 장기적 신뢰성에 문제가 발생한다. 인입된 커넥터 내부 가이드 핀에만 에폭시접착으로 인한 외부 인장력에 한계가 있다. 접속시 위치고정점의 일치화에 애로사항으로 조립접속손실이 높게 발생된다.The multi-core packaged optical connector has a problem of long-term reliability due to cracking and dropping of the guide pin due to external vibration and shock. There is a limit to the external tension due to epoxy bonding only on the guide pin inside the inserted connector. When connecting, the assembly connection loss is high due to the difficulty of matching the position fixing point.

본 발명이 이루고자하는 기술적 과제는 인장력, 충격, 진동등의 신뢰성 특성이 강하며, 저손실 구조인 다심 일괄형 광커넥터를 제공하는데 있다.The technical problem to be achieved by the present invention is to provide a multi-core package type optical connector having a high tensile strength, impact, vibration and reliability characteristics, and a low loss structure.
