Abstract

PURPOSE: A multi module type optical adaptor is provided to simplify a coupling method, thereby eliminating coupling orientation. CONSTITUTION: A plurality of optical adaptors are integrated. When two optical connectors are coupled, a partition wall(23) between the optical connectors is integrated with the optical connectors, thereby reducing the size of a multi module type optical adaptor. A coupling recess(21) is formed on both partition walls of each connector coupling part, thereby eliminating coupling orientation. An optical adaptor blade(22) is formed on right and left sides of a multi modularized optical adapter, thereby simplifying a coupling work.

본 발명은 광섬유케이블을 용이하게 연결하기 위한 광커넥터끼리 연결시켜주는 광어뎁터에 관한 것이다.The present invention relates to an optical adapter that connects optical connectors for easily connecting optical fiber cables.

광어뎁터(10)는 광분배함, 광카세트광모듈, 광단자함 등과 같은 중계함은 물론 각 종 통신 단말장치에서 단일모드 및 다중모드 광섬유에 대응하기 위하여 사용되는데, 도1(종래의 광어뎁터의 모습)을 참조해 광어뎁터에 대해 상세히 설명한다.The optical adapter 10 is used to cope with single-mode and multi-mode optical fiber in various communication terminal devices as well as relay boxes such as optical distribution box, optical cassette optical module, optical terminal box, and the like. The optical adapter will be described in detail.

일반적으로 광어뎁터(10)는 심플렉스(Simplex)로 구성되어 있으며 광섬유(40) 끝단의 광커넥터(30)와 도2(종래의 광어뎁터에 광커넥터를 연결하는 모습)와 같이 푸쉬풀 형태로 결합된다. 이때, 광커넥터(30)의 결합용 돌기(31)는 광어뎁터(10)의 결합용 홈(11)의 방향에 맞추어 결합해야 한다.In general, the optical adapter 10 is composed of a simplex and in the form of a push-pull as shown in FIG. 2 (the optical connector connected to a conventional optical adapter) and the optical connector 30 at the end of the optical fiber 40. Combined. At this time, the coupling protrusion 31 of the optical connector 30 should be coupled in accordance with the direction of the coupling groove 11 of the optical adapter 10.

또한, 여러 개의 광커넥터(30)를 연결하기 위해서는 도3(다수개의 종래의 광어뎁터에 광커넥터를 연결하여 배열한 모습)과 같이 해당 개수만큼의 광어뎁터(10)를 필요로 하며, 광분배함, 광카세트모듈, 광단자함 등의 광연결을 위한 장치 및 유닛에 이들 광어뎁터(10)를 고정하기 위해서는 각 각의 광어뎁터(10) 상하에 구비된 날개(12)의 나사체결용 구멍을 이용하여 일일이 나사로 고정해야 한다.In addition, in order to connect a plurality of optical connectors 30, as many as the number of optical adapters 10 as shown in Fig. 3 (a state in which an optical connector is connected to a plurality of conventional optical adapters arranged), the optical distribution In order to fix these optical adapters 10 to devices and units for optical connection such as a box, an optical cassette module, an optical terminal box, and the like, the holes for screwing the blades 12 provided in the upper and lower portions of the optical adapters 10 are It should be screwed one by one.

이상 설명한 바와 같이 종래의 광어뎁터(10)를 이용하여 여러 개의 광커넥터를 연결하고자 하면 해당 개수 만큼의 광어뎁터(10)가 필요하며, 광커넥터(30)의 결합용 돌기(31)를 광어뎁터(10)의 결합용 홈(11)의 방향에 맞추어야하며, 각 각의 광어뎁터를 나사로 고정해야 하는 불편함이 있다. 이는 곧 광어뎁터(30) 점유공간을 증가시킬 수 밖에 없으므로 광분배함, 광카세트모듈, 광단자함 등에 광어뎁터(30)를 장착할 수 있는 충분한 여유공간을 확보해야 했다. 다시 설명하면 일정 공간을 점유하는 광어뎁터(30) 때문에 공간활용에 제약을 받을 수 밖에 없으므로 광분배함, 광카세트모듈, 광단자함 등의 소형화에 영향을 끼칠 수 밖에 없으며, 광어뎁터(10)의 장착에 불편을 초래했다.As described above, in order to connect a plurality of optical connectors using the conventional optical adapter 10, the number of optical adapters 10 is required, and the coupling protrusion 31 of the optical connector 30 is connected to the optical adapter. It is necessary to match the direction of the coupling groove 11 of (10), there is an inconvenience to fix each optical adapter with a screw. This will soon increase the space occupied by the optical adapter 30, so it was necessary to secure sufficient free space to mount the optical adapter 30 to the optical distribution box, optical cassette module, optical terminal box. In other words, since the optical adapter 30 occupies a certain space, it is inevitably limited to use of the space, and thus, the optical adapter 30 may have an effect on miniaturization of an optical distribution box, an optical cassette module, an optical terminal box, and the like. It caused inconvenience in mounting.

이에 본 발명은 상기와 같은 문제를 해소하기 위해 안출된 것으로, 다수개의 광어뎁터(10)를 일체화 하여 크기를 축소하고 모듈화시켜 광분배반, 광카세트모듈, 광단자함 등의 유닛에서 공간활용을 자유롭게 하고, 고정을 위한 체결방식을 단순화 시켜 작업의 용이성을 제공하고, 광커넥터(30)의 결합 방향성을 없애 작업에 혼돈이 없도록 하는 광어뎁터이다.Accordingly, the present invention has been made to solve the above problems, by reducing the size and modularization by integrating a plurality of optical adapter 10 to free space utilization in units such as optical distribution panel, optical cassette module, optical terminal box and the like. To simplify the fastening method for fixing, to provide ease of operation, eliminating the coupling direction of the optical connector 30 is an optical adapter so that there is no confusion in the operation.
