Description

다심 광커넥터용 페룰의 제조 금형Manufacturing mold of ferrule for multi-core optical connector

본 발명은 복수개의 광화이버를 일괄적으로 접속시킬 수 있는 다심 광커넥터에 관한 것으로, 특히 사출 성형에 의하여 가공정밀도를 항상시킴과 아울러 생산사이클을 단축시키도록 한 다심 광커넥터용 페룰의 제조 금형에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multicore optical connector capable of collectively connecting a plurality of optical fibers, and more particularly, to a mold for manufacturing a ferrule for a multicore optical connector which minimizes production cycles and minimizes processing accuracy by injection molding. It is about.

일반적으로 광화이버 일괄적으로 접속시키는 광커넥터용 페룰 중 단심 페룰은 제1도에 도시한 바와 같이, 세라믹 페룰(1)을 성형한 후에 광화이버 삽입홀(미도시)을 내경에 연마하여 광화이버(2)를 삽입하여 사용한다.In general, the single-core ferrule among the optical connector ferrules connected to the optical fibers collectively, as shown in FIG. 1, is formed by polishing the optical fiber insertion hole (not shown) to the inside diameter after forming the ceramic ferrule 1 Insert and use (2).

그러나 사익 단심 세라믹 페룰은 세라믹 소결 후에 약 0.12㎛인 내경의 공차를 맞추기 위한 연마를 실시해주어야 하므로 공정이 과다하고, 이와 같이 제조된 커넥터의 단가가 높아 가격경쟁력이 떨어지는 문제가 있다.However, since the single-core single-core ceramic ferrule needs to be polished to meet the tolerance of the internal diameter of about 0.12 μm after sintering the ceramic, the process is excessive, and the cost of the connector manufactured as described above is high, resulting in a low price competitiveness.

따라서 하나의 페룰에 복수심의 광화이버를 일괄적으로 접속시킬 수 있는 다심 광커넥터를 제조하기 위한 기술이 개발되고 있는 바, 이러한 다심 광커넥터용 페룰의 일례로서, 제2도 내지 제4도에 도시한 바와 같이, 에폭시 수지 등의 플라스틱 성형 재료를 사용하여 성형된 페룰(10)이 사용되고 있다.Therefore, a technology for manufacturing a multi-core optical connector capable of collectively connecting a plurality of optical fibers to one ferrule has been developed. As an example of such a ferrule for a multi-core optical connector, it is shown in FIGS. 2 to 4. As mentioned above, the ferrule 10 shape | molded using plastic molding materials, such as an epoxy resin, is used.

상기 다심 광커넥터용 페룰(10)은 중앙에 광화이버를 삽입하기 위한 세공(11)이 형성되어 있고, 그 양측에는 다심광 커넥터의 정확한 위치를 결정하기 위한 가이드핀이 결합되는 가이드공(12)이 형성되어 있다.The multi-core optical connector ferrule 10 has a hole 11 for inserting an optical fiber in the center, and guide holes 12 coupled to both sides thereof with guide pins for determining an accurate position of the multi-core optical connector. Is formed.

상기한 바와 같은 타입의 페룰(10)은 한쌍의 상,하부금형(20), (30)과 코어핀 (41), (42)을 고정한 슬라이더(40)를 이용하여 트랜스퍼 성형에 의해 성형이 이루어지 게 된다.The ferrule 10 of the type described above is formed by transfer molding using a pair of upper and lower molds 20 and 30 and a slider 40 fixing the core pins 41 and 42. Will lose.

상기 금형중 하부긍형(30)에는 광화이버 삽입용 세공(11) 및 가이드핀 결합용 가이드공(12)을 형성하기 위한 코어핀(41), (42)을 셋팅하는 브이흠(31)이 복수개 형성된 브이흠부(32)를 갖고 있다. 또한, 상부금형(20)에는 수지의 통로(21)가 형성되어 있다.The lower mold 30 of the mold has a plurality of V-arms 31 for setting the core pins 41 and 42 for forming the optical fiber insertion hole 11 and the guide pin coupling guide hole 12. It has the formed V-groove 32. In the upper mold 20, a resin passage 21 is formed.

이와 같이 구성되어 있는 금형에 의하여 페룰을 성형할 때는, 먼저 하부금형 (30)에 슬라이더(40)를 셋팅하고, 상부금형(20)의 유로(21)를 통하여 상,하부금형 (20), (30)에 트랜스퍼 성형기로 수지를 주입한다. 이와 같이 상,하부금형(20), (30)에 주입된 수지가 경화되면, 슬라이더(40)를 인출시켜 페룰(10)을 취출함으로써 다심 광 커넥터(10'), (10)가 제조된다.When molding the ferrule by the mold configured as described above, first, the slider 40 is set in the lower mold 30, and the upper and lower molds 20, and (through the flow path 21 of the upper mold 20). 30) is injected into the transfer molding machine. When the resin injected into the upper and lower molds 20 and 30 is cured as described above, the multi-core optical connectors 10 'and 10 are manufactured by taking out the slider 40 and taking out the ferrule 10.

이상과 같이 제조된 다심 광커넥터(10'), (10')는 사용할 때 접속부에서의 용이하게 착탈이 가능함과 아울러 결합시 광화이버가 서로 정밀하제 동심으로 결합되어야 한다.The multi-core optical connectors 10 'and 10' manufactured as described above can be easily detached and detached from the connection part when used, and optical fibers must be concentrically coupled to each other at the time of coupling.

이때, 접속손실이 낮은 광커넥터를 얻기 위해서는 페룰의 편심이 작아야되 며, 이를 가능하게 하는 페룰을 얻기 위해서는 금형(30)의 브이흠(31)의 가공정밀도를 향상시켜야 한다.At this time, in order to obtain an optical connector with a low connection loss, the eccentricity of the ferrule must be small, and in order to obtain a ferrule enabling this, it is necessary to improve the processing precision of the V defect 31 of the mold 30.

그러나 현실적으로 브이홈의 정밀한 가공은 상당한 기술적 어려움이 있으며, 길수적 어려움이 있으며,따라서 고정밀도의 금형을 얻는 것이 매우 힘든 실정이다.However, in reality, the precise processing of the V-groove has considerable technical difficulties, and there is a long list of difficulties, so it is very difficult to obtain a high-precision mold.

또한, 상기한 바와 같은 트랜스퍼 성형에 의한 다심 광커넥터용 페룰의 제조방법은 1회 성형을 위한 사이클 타임의 길기 때문에 생산성이 저하되는 문제가 있다.In addition, the manufacturing method of the ferrule for multi-core optical connectors by transfer molding as described above has a problem that productivity is lowered because of a long cycle time for one-time molding.

본 발명의 목적은 고정밀도에 의한 다심 커넥터용 페룰을 사출성형에 의해 실시함으로떠 생산성을 향상시키려는 것이다.An object of the present invention is to improve productivity by performing injection molding of a multi-core ferrule for high precision connectors.

본 발명의 다른 목적은 커넥터 핀 내경의 성형의 정밀도를 향상시키고, 핀간 피치오차의 범위를 극소화시키기 위한 고정밀도의 금형을 얻도록 하려는 것이다.Another object of the present invention is to obtain a mold of high precision for improving the precision of forming the connector pin inner diameter and minimizing the range of pitch error between pins.
