본 고안은 칩형(Chip Type) 3단자 전자파장애(EMI:Electro Magnetic Interference)방지필터에 관한 것으로. 특히 페라이트코어의 중앙부에 콘덴서 삽입공간을 갖춤으로서 제품의 크기를 소형화하고, 신뢰도를 높이며 제조공정의 간소화로 생산원가를 절감할수 있는 전자파장애 잡음제거용 3단자필터에 관한 것이다.The present invention relates to a chip type three-terminal electromagnetic interference (EMI) prevention filter. In particular, the present invention relates to a three-terminal filter for removing electromagnetic interference noise, which has a capacitor insertion space in the center of the ferrite core, which can reduce the size of the product, increase the reliability, and reduce the production cost by simplifying the manufacturing process.
일반적으로 전자기기및 회로간에 발생되는 전자파장애(Electro Magnetic Interference)는 도전선로나 공중을 타고 전파되어 주변기기및 회로에 노이즈(noize)를 발생시켜 오동작을 일으키게 된다.In general, electromagnetic interference generated between electronic devices and circuits propagates through conductive lines or the air, causing noise to peripheral devices and circuits, causing malfunctions.
따라서, 상기와같은 전자파장애를 제거하기 위하여 페라이트 비드나, 또는 콘덴서와 페라이트를 조합하여 만든 3단자필터를 주로 사용하고 있다.Therefore, in order to eliminate such electromagnetic interference, ferrite beads or a three-terminal filter made by combining a capacitor and a ferrite are mainly used.
즉, 이와같은 기술과 관련된 종래의 전자파장애(EMI)방지필터(20)에 있어서는 제1도에 도시한 바와같이, 콘덴서(21)를 개재하여 양측에 페라이트비드(22)(23)를 설치하고 이를 리드선(24)에 의해 연결한 구조로 이루어졌다.That is, in the conventional electromagnetic interference (EMI) prevention filter 20 associated with such a technique, as shown in FIG. 1, ferrite beads 22 and 23 are provided on both sides via a capacitor 21. This is made of a structure connected by the lead wire (24).
상기와같은 구성을 갖는 종래의 전자파장애 방지필터는 콘덴서(21)의 양측에 설치된 페라이트비드(22)(23)의 노이즈(noize) 흡수효과와 로우패스(Low pass)필터효과로 디지털 신호 단형파의 파형왜곡을 막을수 있고, 특히 고주파노이즈 억제기능을 보유하고 있어 인터페이스용으로 널리 사용되는 것이다.The conventional electromagnetic interference prevention filter having the above configuration has a digital signal short wave by the noise absorption effect and the low pass filter effect of the ferrite beads 22 and 23 provided on both sides of the capacitor 21. It is possible to prevent the waveform distortion of the device, and it has a high frequency noise suppression function, so it is widely used for the interface.
그러나, 상기와같은 전자파장에 방지필터를 제작하기 위해서는 제조공정상 콘덴서(21)의 접합등이 자동화가 불가능한 단점이 있음은 물론, 콘덴서(21)의 하방양측으로 페라이트 비드(22)(23)를 리드선(24)에 연결 접속시킨 구조로 이루어짐으로써, 구조자체가 복잡하고, 높이가 크게되어 슬림(Slim)화가 어려우며 필터의 제작이 비능률적인 단점이 있었다.However, in order to manufacture a filter for electromagnetic waves as described above, there is a disadvantage in that the bonding of the capacitor 21 is not possible in the manufacturing process, and the ferrite beads 22 and 23 are disposed on both sides of the capacitor 21 downward. Since the structure is connected to the lead wire 24, the structure itself is complicated, the height is large, slimming is difficult, and the manufacturing of the filter is inefficient.
뿐만 아니라, 다층 세라믹 콘데서(MLCC)를 사용하지 않기 때문에 절연저항의 능력이 매우 커야되며, 전자기기상에 장착하는 작업 또한 어려운 것이었다.In addition, since the multilayer ceramic capacitor (MLCC) is not used, the ability of the insulation resistance must be very large, and mounting on the electronic device was also difficult.
본 고안은 상기와같은 종래의 문제점을 해소하기 위한 것으로, 완제품의 크기를 소형화할수 있고, 고전압에서 충분한 내압및 특성을 유지할수 있으며, 제조공정을 단순화함으로서 완제품의 생산원가도 절감할수 있도록 개선된 전자파장애 잡음제거용 3단자 필터를 제공함에 그 목적이 있다.The present invention is to solve the conventional problems as described above, it is possible to miniaturize the size of the finished product, to maintain sufficient breakdown voltage and characteristics at high voltage, and to improve the electromagnetic wave to reduce the production cost of the finished product by simplifying the manufacturing process The purpose is to provide a three-terminal filter for the interference noise cancellation.

또한, 상기형 단자선(15)는 콘덴서(12)의 상부면을 가로지르는 중앙부분에 납땜 연결부(17)가 형성되어 결합되고, 상기 페라이트코어(1)의 상부면과, 단자선(19)은 절연피복제로서 일체로 결합되는 구조를 갖는다.Also, the The type terminal line 15 has a solder joint 17 formed at a central portion across the upper surface of the condenser 12 and is coupled. The upper surface of the ferrite core 1 and the terminal line 19 are insulated from each other. It has a structure that is integrally coupled as a replica.
상기와같은 본 고안의 3단자필터(1)를 제조하는 단계가 제3도상에 순서적으로 도시되어 있다.The steps of manufacturing the three-terminal filter 1 of the present invention as shown above are shown in sequence in FIG.
먼저, 페라이트코어(11)과 콘덴서(12)를 연결시키고 상기 콘댄서(12)의 상부면을 가로지르도록형 단자선(15)를 끼운다음, 상기 단자선(15)과 콘덴서(12)의 상부면을 납땜연결하고. 단자선(15)과 페라이트코어(11)의 상부면을 절연도포제로서 일체로 결합시키는 것이다. 한편, 상기에서형 단자선(15)은 콘덴서(12)와의 접촉면적을 확대시키기 위하여 중간지점에형 절곡부(15a)또는 납작누름부(15b)를 갖출수도 있는 것이다.First, the ferrite core 11 and the condenser 12 are connected to cross the upper surface of the condenser 12.

The upper surface of the terminal line 15 and the ferrite core 11 are integrally combined as an insulating coating agent. On the other hand, in the above Type terminal line 15 is provided at an intermediate point to enlarge the contact area with the condenser 12. It is also possible to have a bent portion (15a) or flat pressing portion (15b).
