관통형 세라믹 콘덴서의 제조방법Manufacturing method of through ceramic capacitor

제 1a, b, c 도는 본 발명의 제조공정도.1a, b, c or manufacturing process diagram of the present invention.

제 2 도는 본 발명의 실시사용상태 예시도.2 is an exemplary view showing a state of use of the present invention.

제 3 도는 공지한 콘덴서의 단면 예시도.3 is a cross-sectional view of a known capacitor.

본 발명은 관통형 세라믹 콘덴서의 제조방법에 관한 것으로, 티탄산바륨(BaTi O3)에 각각 3%, 2% 정도의 바인더(binder)를 혼합교반한 습식 티탄산바륨 교반물을 압출 성형하여 각각 환형후렌지체와, 이의 내경과 동일한 외경을 갖는 원통체를 각각 성형한 다음, 원통체의 외주면 상부에 환형 후렌지체를 감합하여 통상과 같이 소결하여 관통형 세라믹콘덴서를 제조함으로서 세라믹콘덴서의 제조작업을 간단하고 용이하게 수행할 수 있도록 함과 동시에 환형후렌지와 원통체의 성형시 성형물의 압력상태를 균일하게 유지되게 하여 이를 감합한 다음 소결할 때 환형 후렌지체나 원통체의 크랙크(crack) 현상이 나타나지 않게 하여 양질의 우수한 관통형 세라믹콘덴서를 간단하게 양산할 수 있도록 한 것이다.The present invention relates to a method for manufacturing a through-type ceramic capacitor. Extrusion of a wet barium titanate agitated by mixing and stirring a barium titanate (BaTi O 3 ) of about 3% and 2%, respectively, to annular flanges The work of manufacturing ceramic capacitors is simplified by forming a sieve and a cylindrical body having the same outer diameter as its inner diameter, and then fitting the annular flange body to the upper portion of the outer circumferential surface of the cylindrical body and sintering as usual. It can be easily carried out and at the same time maintains the pressure state of the molded part uniformly when forming the annular flange and the cylindrical body, so as to fit and then cracks of the annular flange or the cylindrical body when sintering It is to make mass production of high quality excellent through ceramic capacitor simple.

종래 일반적인 관통형 세라믹콘덴서의 제조에 있어서는 대체로 분말 성형용 금형에 티탄산바륨분말을 충전시킨 다음 관통형 세라믹콘덴서의 후렌지체와 원통체를 일시에 프레스 가공하여 일체로 성형하는 방법을 채택하고 있으나, 일반적인 관통형 세라믹콘덴서는 대체로 전장(L)이 길고 이에 비하여 두께(T) 및 폭(D)이 좁기 때문에 고도의 정밀한 금형이 필요로 하는 한편, 금형에 티탄산바륨분말을 충입하고 이를 압착하여 관통형세라믹 콘덴서를 성형함에 있어서도 균일한 압력으로 관통형 세라믹콘덴서의 형태를 성형할 수 없는 결점이 나타나 소결시 관통형 세라믹 콘덴서 자체에 크랙크현상이 나타나게 되어 불량품이 많이 발생하게 되므로서 원가상승의 요인이 되는 비경제적인 결함이 있었을 뿐만 아니라, 완제품의 생산작업성이 극히 저조한 결함이 있었다.Conventionally, in the manufacture of a general through-type ceramic capacitor, a method of forming a powder molding die by filling a barium titanate powder and then pressing and processing the flange body and the cylindrical body of the through-type ceramic capacitor at a time is integrated. Through-hole ceramic capacitors generally require a high-precision mold because they have a longer length (L) and a smaller thickness (T) and width (D), while barium titanate powder is charged into the mold and compressed to penetrate through-type ceramics. Even when molding a capacitor, there is a defect that the shape of the through-type ceramic capacitor cannot be formed at a uniform pressure, so that cracks appear in the through-type ceramic capacitor itself during sintering, causing a lot of defective products, resulting in a cost increase. Not only was it an uneconomical defect, but the production workability of the finished product was extremely poor. There was a must.

본 발명은 상기와 같은 종래의 제반 결함을 제거하고, 간단한 제조공정으로 분말성형하여 제조한 관통형 세라믹콘덴서 보다 우수한 양질의 관통형 세라믹콘덴서를 량산할 수 있도록 한 것으로, 각각 바인더분을 3% 또는 2% 정도 혼합하여 교반한 습식 티탄산 바륨교반물을 압출하여 환형후렌지체와 원통체를 각각 별도로 성형하고, 이를 적당한 길이로 절단한 다음, 원통체 외주 상부에 환형후렌지체를 감합, 소결하여 관통형 세라믹콘덴서를 제조함으로서 그 제조방법이나 공정이 극히 간편하여 작업능률을 향상시킬 수 있을 뿐만 아니라, 환형후렌지체와 원통체를 압출 성형함에 있어서는 습식 티탄산바륨 교반물을 일정한 압력상태로 균일하게 압출시켜 성형할 수 있게 되므로서 원통체 내주에 환형후렌지체를 감합시켜 소결시 압축 압력 불균형에 의한 크랙크현상이 완벽하게 방지되어 우수한 양질의 관통형 세라믹콘덴서를 양산하여 염가로 제공할 수 있도록 한 것으로, 이를 첨부한 공정도면에 따라 상술하면 다음과 같다.The present invention is to remove the above-mentioned conventional defects, and to mass-produce better quality through-type ceramic capacitors than through-type ceramic capacitors manufactured by powder molding in a simple manufacturing process. Extrude the stirred barium titanate mixture by mixing about 2%, and shape the annular flange body and the cylindrical body separately, cut them to the appropriate length, and then fit and sinter the annular flange body on the upper portion of the cylindrical body through By manufacturing ceramic capacitors, the manufacturing method and process are extremely simple to improve the work efficiency. In addition, in the extrusion molding of the annular flange body and the cylindrical body, the wet barium titanate stirring material is uniformly extruded under a constant pressure. Since it is possible to fit the annular flange body to the inner circumference of the cylindrical body, One crack phenomenon is completely prevented to provide a high-quality through-through ceramic capacitor of high quality to provide at a low cost, as described above according to the accompanying process drawings.

제 1a, b, c 도는 본 발명의 제조공정을 나타낸 것으로서, 티탄산바륨 전체량에 대하여 바인더3% 정도를 혼합한 습식 티탄산바륨교반물을 압출 성형하여 적당한 길이로 절단하여 환형후렌지체(1)를 성형함과 동시, 티탄산바륨전체량에 대하여 2% 정도의 바인더를 혼합, 교반한 습식 티탄산바륨교반물을 역시 압출 성형하여 적당한 길이로 절단하여 원통체(2)를 성형하는 한편, 환형후렌지체(1)의 내경(R1)과 원통체(2)의 외경(R2)를 동일하게 형성한다(제 1 공정).1a, b, and c show the manufacturing process of the present invention. The wet barium titanate agitated mixture of about 3% of the total amount of the barium titanate is extruded and cut into suitable lengths to form the annular flange 1 Simultaneously by molding, the wet barium titanate agitated mixture of about 2% of the total amount of barium titanate was also extruded and cut into a suitable length to form the cylindrical body 2, while The inner diameter R 1 of 1 ) and the outer diameter R 2 of the cylindrical body 2 are formed in the same manner (first step).

상기와 같이 압출 성형된 원통체(2)의 외경(R2)에 환형 후렌지체(1)의 내경을 감합시킨 다음, 통상의 방법과 같이 소결한다. 이때 원통체(2)의 습식티탄산바륨 교반물에는 바인더가 전체량에 대하여 2% 정도 혼합되어 있고, 환형후렌지체(1)의 습식티탄산바륨 교반물에는 전체량에 대하여 바인더분이 3% 정도 혼합되어 있으므로서 소결시 원통체(2) 외경(R2)의 수축율보다 환형후렌지체(1) 내경(R1)의 수축율이 크게 되므로서 원통체(2)의 외주면에 환형후렌지체(1)의 내주면이 완전히 밀착된 상태로 소결되게 되어 원통체(2)로부터 환형후렌지체(2)가 분리 이탈되는 현상이 발생되지 않으며, 또한 원통체(2)와 환형후렌지체(1)는 모두 습식 티탄산바륨 교반물을 압출하여 각각 별도로 성형하게 되어 환형후렌지체(1)과 원통체(2)의 압축 성형상태가 균일하고 양호하여, 소결시 압축 불균형에 의하여 열수축되어 크랙크 현상이 나타나는 사례가 전혀 발생하지 않게 되어 양질 상태의 관통형 세라믹콘덴서(3)을 소성하게 된다(제 2 공정).The inner diameter of the annular flange body 1 is fitted to the outer diameter R 2 of the cylindrical body 2 extruded as described above, and then sintered in the usual manner. In this case, about 2% of the binder is mixed with the wet barium titanate agitator of the cylindrical body 2, and about 3% of the binder content is mixed with the wet barium titanate agitator of the annular flange 1 since standing sintering when the cylindrical body (2) outer diameter (R 2) of the shrinkage ratio than the inner circumferential surface of the annular flange member (1) inner diameter (R 1) an annular flange element (1) on the outer peripheral surface of the standing cylindrical body (2) is larger, because the shrinkage of the The sintered state is brought into close contact with the cylindrical body 2 so that the annular flange 2 is not separated and separated from the cylindrical body 2, and both the cylindrical body 2 and the annular flange body 1 are wetted with barium titanate. Water is extruded and molded separately, so that the compression molding state of the annular flange body 1 and the cylindrical body 2 is uniform and good, so that there is no case of thermal shrinkage due to compression imbalance during sintering. In good condition It is a plastic-type ceramic capacitor (3) (second step).

이와 같이 소성한 관통형세라믹콘덴서(3)에 통상과 같이 온도금(4)하고, 원통체(2)의 삽통공(2')에 전극단자(5)를 관통 시킨 다음, 이의 상, 하부를 용접(6)하여 관통형 세라믹콘덴서(3)을 완성한다(제 3 공정).The sintered ceramic capacitor 3 calcined in this manner is subjected to the temperature gold 4 as usual, and the electrode terminal 5 is passed through the insertion hole 2 'of the cylindrical body 2, and then the upper and lower portions thereof are removed. Welding (6) completes the through ceramic capacitor (3).

이와 같은 본 발명은 내, 외경이 동일한 환형후렌지체(1)와 원통체(2)를 각각 바인더 함량이 다른 습식 티탄산 바륨교반물을 압출하여 성형하게 되므로서 환형후렌지체 (1)와 원통체(2) 자체성형시의 압력상태를 균일하게 유지시켜 주어 원통체(2) 외주에 환형후렌지체(1)를 감합, 소결하여 관통형세라믹콘덴서(3)을 성형할 때 압력 불균형에 의한 크랙크현상이 완벽하게 방지되어 우수한 량질의 관통형 세라믹 콘덴서를 제조할 수 있을 뿐만 아니라, 그 제조방법이나 공정이 간단하여 량산할 수 있게 되어 우수한 량질의 관통형 세라믹 콘덴서의 제조단가를 절감시켜 염가로 제공할 수 있는 특징을 지닌 것이다.In the present invention, the annular flange body 1 and the cylindrical body 2 are formed by extruding the wet barium titanate agitator having the same binder content, respectively, with the same inner and outer diameters. 2) Cracking phenomenon due to pressure imbalance when forming the through-type ceramic capacitor 3 by fitting and sintering the annular flange body 1 to the outer circumference of the cylindrical body 2 by maintaining the pressure state during self-forming uniformly. This perfectly prevented not only can produce a good quality through-through ceramic capacitor, but also can be easily manufactured in a large amount by the manufacturing method or process thereof, thereby reducing the manufacturing cost of a good quality through-through ceramic capacitor and providing it at low cost. It has the features to be.
