Title
(EN) Chip type aluminum electrolytic capacitor
(ZH) 片状铝电解电容器
Abstract
(EN) The present invention provides an chip type aluminum electrolytic capacitor which raises the temperature of a lead wire exposed from an insulation terminal board earlier than other components, allows a highly reliable soldering in a comparatively slow reflow atmospheric environment, and is excellent in vibration resistance. The capacitor comprises an insulation terminal board (3) that is provided in the outer surface thereof with an insertion hole (2a) through which a pair of lead wires (2) led out form the sealing member of a capacitor body are inserted and a first recessed groove (5) for housing the lead wires (2) passed through this hole and bent perpendicularly, and that is mounted so as to contact the sealing member. A metal electrode (4) is embedded in the inner surface and its vicinity of the first recessed groove (5) provided in the insulation terminal board (3), with part of the metal electrode (4) exposed to the end surface (3a) of the insulation terminal board (3). A bidirectional second recessed groove (6) reaching the ends (3a1, 3a2) of the insulation terminal board from the insertion hole in the insulation terminal board (3) is provided.
(ZH)

本发明提供一种片状铝电解电容器,该片状铝电解电容器使从绝缘端子板显露的引线温度先于其它部分上升、在比较慢的回流气氛环境下可进行可靠性高的焊接,且耐振动性优异。片状铝电解电容器其包括以与所述封口部件抵接的方式安装的绝缘端子板(3),绝缘端子板在外表面具有从电容本体的封口部件导出的一对引线(2)所插通的插通孔(2a),及将插通该插通孔的引线(2)向直角方向弯曲进行容纳的第一凹槽(2a)。在设置于绝缘端子板(3)上的第一凹槽(2a)的内面及其周缘埋入金属电极(4)。并且,使金属电极(4)的一部分在绝缘端子板(3)的端面部(3a)显露。具有从绝缘端子板(3)的插通孔到绝缘端子板的端部(3a1、3a2)的双方向的第二凹槽(6)。
