Description

트랜스포머용 1차코일 사출 성형물{Primary coil injection molding for Transformers}{Primary coil injection molding for Transformers}

본 발명은 트랜스포머용 1차코일 사출 성형물에 관한 것이다.The present invention relates to a primary coil injection molded article for a transformer.

트랜스포머는 전자 상호 유도 작용을 이용하여 교류 전압을 높이거나 낮추는 장치로, 1차코일, 2차코일 및 자심으로 이루어진다.A transformer is a device that raises or lowers an alternating voltage using an electromagnetic interaction, and consists of a primary coil, a secondary coil, and a magnetic core.

예를 들어, 중심부가 개구된 판 형상의 하부 2차코일 성형물, 1차코일 성형물 및 상부 2차코일 성형물을 기둥 형태의 자심에 순차적으로 외삽하여 적층되도록 해서 트랜스포머를 구현할 수 있다. 이때 1차코일 성형물 내의 1차코일에 교류 전압이 인가되고 하부 2차코일 성형물 및 상부 2차코일 성형물 내의 2차코일로 변압된 교류 전압이 출력된다.For example, a transformer may be realized by sequentially extruding a plate-shaped lower secondary coil molding, a primary coil molding, and an upper secondary coil molding, which are open at the center, onto a columnar core. At this time, an alternating voltage is applied to the primary coil in the primary coil molding and the alternating voltage converted to the secondary coil in the lower secondary coil molding and the upper secondary coil molding is output.

여기서 하부 2차코일 성형물, 1차코일 성형물 및 상부 2차코일 성형물의 내부에 해당 코일이 견고하게 접착되는 것이 중요하다.Here, it is important that the coil is firmly adhered to the inside of the lower secondary coil molding, the primary coil molding, and the upper secondary coil molding.

따라서 트랜스포머용 1차코일 사출 성형물 내에 수납되는 1차코일은 에나멜(enamel)로 코팅된 복수의 판 형상 코일이 적층되는 동시에 직렬 연결된 상태이며, 1차코일에 코팅된 에나멜 표면이 열에 의해 약간 녹았다가 굳어 1차코일이 견고하게 접착된 상태를 유지하도록 함으로써 1차코일에 교류 전압이 인가됨에 따라 흐르는 교류 전류에 수반되는 진동에 의해 소음이 발생하거나 그 진동에 수반되는 열에 의해 1차코일에 코팅된 에나멜이 과도하게 녹아 단락이 발생하는 것이 방지되도록 할 필요가 있다.Therefore, the primary coil housed in the primary coil injection molded product for a transformer is a laminate of a plurality of plate-shaped coils coated with enamel and is connected in series, and the enamel surface coated on the primary coil is slightly melted by heat So that the primary coil is stably adhered to the primary coil so that noise is generated due to the vibration accompanied by the AC current flowing as the AC voltage is applied to the primary coil or the primary coil is coated with the primary coil It is necessary to prevent the occurrence of short circuit due to excessive melting of enamel.

트랜스포머용 1차코일 사출 성형물 내에 수납되는 1차코일은 에나멜로 코팅된 복수의 판 형상 코일이 적층되는 동시에 직렬 연결된 상태이며, 1차코일에 코팅된 에나멜 표면이 열에 의해 약간 녹았다가 굳어 1차코일이 견고하게 접착된 상태를 유지하도록 하지는 못한다.Primary Coil for Transformer The primary coil housed in the injection-molded product is a plurality of plate-shaped coils coated with enamel, which are laminated and connected in series. The enamel surface coated on the primary coil is slightly melted by heat, The coil can not be maintained in a firmly adhered state.
