Description

광커넥터 모듈{Optical connector module}Optical connector module

본 발명은 광소자와 광섬유를 커플링하는 광커넥터 모듈에 관한 것이다.The present invention relates to an optical connector module for coupling an optical element and an optical fiber.

일반적으로 광커넥터 모듈은 광소자와 광섬유를 커플링하여 광이 올바르게 진행되도록 안내하는 것으로, 예컨대 컴퓨터 본체와 버스, 컴퓨터 본체와 모니터,버스와 버스 등의 정보신호를 주고받는 디바이스 사이에 설치되어 광 전송을 통해 기기 사이의 정보가 전달되도록 한다.In general, the optical connector module is to guide the light to proceed correctly by coupling the optical element and the optical fiber, for example, is installed between the computer body and the device that sends and receives information signals, such as the computer body and the monitor, the bus and bus The transmission allows information to pass between devices.

이러한 광커넥터 모듈은, 도 1 및 도 2에 도시된 바와 같이, 광소자(25)와 렌즈(26)(27)가 설치되는 홀더(22)와, 상기 홀더(22)에 일체로 부착되는 어댑터(20)와, 광섬유(1)가 설치되며 상기 어댑터(20)의 후크(28)에 탄력적으로 결합되는 커넥터(10)를 포함하여 구성된다. 참조부호 11은 광섬유(1)의 선단을 지지하는 페룰(ferrule)로서 도 2와 같이 광섬유(1) 선단이 광소자(25)와 마주하도록 상기 어댑터(20)의 결합통(21) 속에 삽입되며, 참조부호 24는 상기 홀더(22) 안에 설치되어 그 위에 광소자(25)가 고정되는 서브마운트를 나타낸다.As shown in FIGS. 1 and 2, the optical connector module includes a holder 22 in which the optical element 25 and the lenses 26 and 27 are installed, and an adapter integrally attached to the holder 22. 20 and the optical fiber 1 is installed and is configured to include a connector 10 that is elastically coupled to the hook 28 of the adapter 20. Reference numeral 11 is a ferrule (ferrule) for supporting the front end of the optical fiber 1 is inserted into the coupling tube 21 of the adapter 20 so that the front end of the optical fiber 1 faces the optical element 25 as shown in FIG. , 24 denotes a submount installed in the holder 22 to which the optical element 25 is fixed.

따라서 상기 광섬유(1)를 통해 들어온 광신호는 상기 홀더(22)의 렌즈(26)(27)를 통해 광소자(25)에 집속된 후 전기신호로 변환되고, 리드핀(23)을 통해 기판(미도시)으로 전송되어 나간다. 반대의 경우도 마찬가지로 광소자(25)에서 출사된 광신호가 렌즈(26)(27)를 통해 광섬유(1)에 집속되어 전송된다. 이러한 광커넥터 모듈은 통상 두 개가 한쌍으로 구비되어서, 하나는 상기와 같이 광신호를 전기신호로 변환하여 검출하기 위한 수광용으로, 다른 하나는 전기신호를 광신호로 변환하여 출사하기 위한 발광용으로 사용되는 것이 일반적이다.Therefore, the optical signal introduced through the optical fiber 1 is focused on the optical element 25 through the lenses 26 and 27 of the holder 22 and then converted into an electrical signal, and the substrate through the lead pin 23. It is sent to (not shown). In the reverse case, the optical signal emitted from the optical element 25 is focused and transmitted to the optical fiber 1 through the lenses 26 and 27. In general, two optical connector modules are provided in pairs, one for receiving light for converting an optical signal into an electrical signal as described above, and the other for emitting light for converting an electric signal into an optical signal and emitting the light. It is common to be used.

그런데, 이러한 구성의 광커넥터 모듈에 있어서는 유리렌즈(26)(27)가 고가인 단점도 있지만, 특히 광소자(25)와 렌즈(26)(27)의 광축을 정확하게 맞추지 못할 경우 신호 전송에 큰 에러가 생기는 단점이 있다. 따라서 이 광축을 맞추는데 많은 작업공수가 필요하게 되어, 결국 이것이 생산성을 저하시키는 요인이 되고 있다. 또한 상기한 바와 같이 수광용과 발광용의 한 쌍을 준비해야 하므로, 부품수도 많아지고 그에 따라 크기가 커지는 문제가 있다.By the way, in the optical connector module of such a configuration, there are disadvantages in that the glass lenses 26 and 27 are expensive, but especially when the optical axes of the optical element 25 and the lens 26 and 27 cannot be accurately aligned, they are large for signal transmission. There is a disadvantage that an error occurs. Therefore, a lot of work is required to match this optical axis, and this eventually becomes a factor which reduces productivity. In addition, as described above, a pair of light-receiving light and light-emitting light must be prepared, which causes a problem in that the number of parts increases and the size thereof increases.

본 발명은 상기한 바를 감안하여 창출된 것으로, 구조 및 조립공정을 간소화하여 소형화 및 생산성 측면에서 유리한 광커넥터 모듈을 제공하는데 그 목적이 있다.The present invention has been made in view of the above, and its object is to provide an optical connector module that is advantageous in terms of miniaturization and productivity by simplifying the structure and assembly process.

상기 목적을 달성하기 위한 본 발명에 따른 광커넥터 모듈은, 광섬유의 선단을 지지하는 어댑터; 상기 어댑터가 삽입되는 결합홈이 형성된 본체; 상기 결합홈 내측에 설치되는 서브마운트; 상기 어댑터가 상기 결합홈에 삽입되면 상기 광섬유의 선단과 마주하도록 상기 서브마운트에 설치된 광소자; 상기 광소자를 소정 기판에 전기적으로 연결시키기 위해 상기 서브마운트에 마련된 리드 패턴;을 포함하는 것을 특징으로 한다.An optical connector module according to the present invention for achieving the above object, the adapter for supporting the front end of the optical fiber; A main body having a coupling groove into which the adapter is inserted; A submount installed inside the coupling groove; An optical element installed in the submount so as to face the front end of the optical fiber when the adapter is inserted into the coupling groove; And a lead pattern provided in the submount to electrically connect the optical device to a predetermined substrate.

이하, 첨부된 도면을 참조하면서 본 발명에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3 및 도 4에 도시된 바와 같이 본 발명의 광커넥터 모듈은, 전면에 결합홈(100a)이 형성된 본체(100)와, 광섬유(1)의 선단을 지지하며 상기 결합홈(100a)에 끼워져 결합되는 어댑터(200)와, 상기 결합홈(100a)의 내측에 설치되며 전면에 수발광소자(111)(112) 및 리드패턴(113)이 각각 마련된 서브마운트(110) 등을 포함하여 구성된다.3 and 4, the optical connector module of the present invention supports the front end of the main body 100 and the optical fiber 1, the coupling groove (100a) is formed on the front and is fitted into the coupling groove (100a) The adapter 200 is coupled to each other, and the submount 110 is installed inside the coupling groove 100a, and the light emitting devices 111 and 112 and the lead pattern 113 are provided on the front surface. .

먼저, 상기 서브마운트(110)에 형성된 복수의 리드패턴(113)은 그 일단이 본딩에 의해 수발광소자(111)(112)와 연결되며, 타단은 상기 서브마운트(110)의 하단부가 소정 기판(미도시)에 결합되면 수발광소자(111)(112)와 기판을 전기적으로 연결시키게 된다.First, one end of the plurality of lead patterns 113 formed on the submount 110 is connected to the light emitting devices 111 and 112 by bonding, and the other end of the plurality of lead patterns 113 is bonded to a lower substrate of the submount 110. When coupled to (not shown), the light emitting devices 111 and 112 are electrically connected to the substrate.

상기 본체(100)는 플라스틱 사출에 의해 제조된다. 즉, 수발광소자(111)(112) 및 리드패턴(113)이 마련된 서브마운트(110)를 본체(100) 모양의 주형에 장착하고 플라스틱을 인젝션함으로써 도면과 같은 본체(100)를 만들어낸다.The body 100 is manufactured by plastic injection. That is, the sub-mount 110 provided with the light emitting elements 111 and 112 and the lead pattern 113 is mounted in a mold having the shape of the main body 100, and the plastic is injected into the main body 100 as shown in the drawing.

상기 어댑터(200)는 광섬유(1)의 선단을 지지하고 있으며, 상기 결합홈(100a)에 끼워져 결합된다. 그리고 어댑터(200)가 결합홈(100a)에 끼워지면, 상기 광섬유(1)의 선단은 상기 수발광소자(111)(112) 각각과 마주하게 된다.The adapter 200 supports the front end of the optical fiber 1 and is fitted into the coupling groove 100a to be coupled thereto. When the adapter 200 is fitted into the coupling groove 100a, the tip of the optical fiber 1 faces each of the light emitting devices 111 and 112.

그리고 상기 광소자(1)와 어댑터(200) 사이는 도 2에 도시된 바와 같이 사출된 본체(100)의 플라스틱 격벽(100b)에 의해 막혀있지만, 광신호의 전송에는 별 지장이 없다. 여기서 사용되는 광신호는 적외선 영역의 빛으로서, 플라스틱 격벽 정도는 별 문제없이 투과하여 전송될 수 있기 때문이다.In addition, although the optical device 1 and the adapter 200 are blocked by the plastic partition wall 100b of the main body 100 as shown in FIG. 2, there is no problem in the transmission of the optical signal. This is because the optical signal used here is light in the infrared region, and the plastic bulkhead can be transmitted through without any problem.

상기 구성의 광커넥터 모듈은 도 2에 도시된 바와 같이 결합홈(100a)에 어댑터(200)가 끼워진 상태로 사용된다. 이 상태에서 광섬유(1)를 타고 전송되어 온 광신호는 상기 수광소자(111)에 감지되어 전기신호로 변환된 후 상기 리드패턴(113)을 따라 기판(미도시)으로 전송된다. 또한 반대로 기판에서 리드패턴(113)을 따라 전송된 전기신호는 상기 발광소자(112)에서 광신호로 변환되며 다시 상기 광섬유(1)에 입사되어 그 광섬유(1)로 연결된 곳으로 전송된다. 따라서 한 광커넥터 모듈 내에서 광신호의 수광 및 발광 작업을 모두 수행하며 신호를 전송할 수 있다.The optical connector module having the above configuration is used in a state where the adapter 200 is inserted into the coupling groove 100a as shown in FIG. 2. In this state, the optical signal transmitted through the optical fiber 1 is detected by the light receiving element 111 and converted into an electrical signal, and then transmitted to a substrate (not shown) along the lead pattern 113. On the contrary, the electrical signal transmitted from the substrate along the lead pattern 113 is converted into an optical signal by the light emitting element 112 and is incident to the optical fiber 1 and transmitted to the place connected to the optical fiber 1. Therefore, it is possible to transmit a signal while performing both light receiving and light emitting operations of the optical signal in one optical connector module.

상술한 바와 같이 본 발명은, 하나의 광커넥터 모듈 안에서 광신호의 수광 및 발광을 모두 수행할 수 있기 때문에 한 쌍의 모듈을 준비해야 했던 종래의 구조보다 장치를 소형화할 수 있으며, 또한 렌즈를 사용하지 않기 때문에 광축을 정렬할 필요가 없게 되어 제조공정을 간소화할 수 있는 장점이 있다.As described above, the present invention can perform both light reception and light emission of an optical signal in one optical connector module, so that the device can be made smaller than the conventional structure in which a pair of modules has to be prepared, and a lens is also used. Since there is no need to align the optical axis there is an advantage that can simplify the manufacturing process.

본 발명은 상기에 설명되고 도면에 예시된 것에 의해 한정되는 것은 아니며, 다음에 기재되는 청구의 범위 내에서 더 많은 변형 및 변용예가 가능한 것임은 물론이다.It is to be understood that the invention is not limited to that described above and illustrated in the drawings, and that more modifications and variations are possible within the scope of the following claims.
