본 고안은 전자부품에 관한 것으로, 보다 상세하게는 인쇄회로 기판상에의 실장이 용이하도록 절연케이스를 사용하여 전자부품 본체를 지지 및 보호하도록 된 리드리스 칩(leadless chip)형 알루미늄 전해콘덴서에 관한 것이나 이러한 구조는 리드리드 칩형 알루미늄 전해콘덴서 뿐만 아니라 기타의 전자부품에 대해서도 동일하게 적용되는 것이다.The present invention relates to an electronic component, and more particularly, to a leadless chip type aluminum electrolytic capacitor which supports and protects an electronic component body using an insulating case to facilitate mounting on a printed circuit board. However, this structure is equally applicable to lead-lead chip type aluminum electrolytic capacitors as well as other electronic components.
일반적으로 이러한 종류의 리드리스 칩형 알루미늄 전해콘덴서는 제2도에서 나타낸 바와 같이 고순도 알루미늄박을 전기화학적으로 에칭(etching)한 후, 양극산화를 행하여 유전체 산화피막을 형성하여 만든 양극박과 에칭만을 행한 음극 알루미늄박과의 사이에 절연지를 넣어 감은 다음, 이 감은 물체에 음극 전기성을 띄게되는 구동용 전해액을 함침하여 구성시킨 콘덴서소자(1a)에 봉구부재(1b)를 장착하여 금속케이스(1c)의 개구부를 통하여 삽입한 후 봉입 가공하여 형성된 전자부품본체(1)에서 리드선(1d)을 인출한 면에 관통구멍(도시하지 않음)과 오목부(2a)를 가지는 절연판(2)을 밀착시켜 상기 절연판(2)의 관통구멍을 통해 인출된 리드선(1d)의 선단부를 압착 가공한 후 상기 절연판(2)의 오목부(2a)내에 절곡 가공하여 밀착시킨 구조로 되어 있으며, 이러한 전자부품은 제5도의 절연판(2)의 오목부(2a)에 압착 절곡된 리드선(1d)에의 납땜공정을 통하여 각종 전자기기의 인쇄회로 기판위에 장착된다.In general, this type of leadless chip type aluminum electrolytic capacitor is electrochemically etched from a high purity aluminum foil as shown in FIG. 2, followed by anodization to form only a dielectric foil to form a dielectric oxide film. Insulating paper is wrapped between the aluminum foil and the cathode, and then the sealing member 1b is attached to the capacitor element 1a formed by impregnating the wound object with a driving electrolyte that exhibits negative electrical conductivity. The insulating plate 2 having the through hole (not shown) and the concave portion 2a is brought into close contact with the surface from which the lead wire 1d is drawn out of the electronic component body 1 formed by inserting through the opening of the opening and sealing. The end portion of the lead wire 1d drawn out through the through hole of the insulating plate 2 is crimped, and then bent into the concave portion 2a of the insulating plate 2 to be in close contact. The electronic component is mounted on a printed circuit board of various electronic devices through the soldering process by the compression bending the lead wires (1d) in the recess (2a) of the fifth degree insulating plate (2).
이러한 리드리스 칩형 알루미늄 전해콘덴서는 제5도에서와 같이 절연판(2)전자부품본체(1)의 리드선(1d)을 인출한 면에 맞닿아 있기 때문에 납땜공정시 플럭스(flux)와 용융된 납이 모세관형상에 의하여 절연판(2)의 관통구멍을 따라 올라가 전자부품본체(1)의 봉구부재를 손상시킬 뿐만 아니라 양극단자와 음극단자 간의 단락 작용(short)을 일으키게 하여 콘덴서로써의 기능을 마비시킬 우려가 많으며, 절연판(2)의 관통구멍을 통해 인출된 리드선(1d)을 압착하여 편평하게 가공한 후 절곡함으로서 리드선(1d)의 압착부분과 절곡부분간의 강도가 약화되게 됨과 동시에 리드선(1d)의 압착가공으로 인하여 제6도와 같이 리드선(1d)의 납땜성향상을 위하여 철(1d1) 및 구리(1d2)의 적층체 표면상에 원래 피복되어 있던 납과 주석의 합금성분(1d3)의 변형으로 납땜성에 문제가 발생되어 세트(set)장착후 외부로부터의 충격 및 진동으로 인한 전자부품본체(1)의 탈락우려가 많으며, 또한 제5도에서의 전자 부품본체(1)는 절연판(2)에 의해 리드선(1d)의 인출 면부분만이 보호되고 있기 때문에 구동시 음극전기성을 띄게 되는 전자부품본체(1)의 금속케이스(1c) 측면과 외부회로와의 접촉 및 손상으로 인한 절연파괴의 우려가 많고, 또한 전자부품본체(1)와 절연판(2)이 압착절곡된 리드선만으로 밀착되어있기 때문에 전자부품본체(1)와 절연판이 서로로부터 떨어질 우려가 많다.Since the leadless chip-type aluminum electrolytic capacitor is in contact with the lead wire 1d of the insulating plate 2 and the electronic component body 1 as shown in FIG. 5, flux and molten lead are prevented during the soldering process. The capillary shape rises along the through-hole of the insulating plate 2 and not only damages the sealing member of the electronic component body 1, but also causes a short circuit between the positive electrode terminal and the negative electrode terminal, thereby paralyzing the function of the capacitor. There are many, and the lead wire 1d drawn out through the through hole of the insulating plate 2 is crimped to be flat and then bent to reduce the strength between the crimped portion and the bent portion of the lead wire 1d and at the same time, Due to the crimping process, soldering is performed by deformation of the alloy component 1d3 of lead and tin, which was originally coated on the surface of the laminate of iron 1d1 and copper 1d2 to improve the soldering property of the lead wire 1d as shown in FIG. Door to the castle There is a lot of concern that the electronic component main body 1 may fall off due to shock and vibration from the outside after the set is installed, and the electronic component main body 1 in FIG. Since only the surface of the lead surface of 1d) is protected, there is a risk of insulation breakdown due to contact and damage of the metal case (1c) side of the electronic component body (1), which exhibits negative electrical conductivity during operation, and external circuits. In addition, since the electronic component body 1 and the insulating plate 2 are brought into close contact with only the crimped lead wires, the electronic component body 1 and the insulating plate are likely to fall from each other.
