FIG. 3 shows a lead-in-same direction electrolytic capacitor 1.
The figure shows the capacitor 1 mounted on a printed circuit board 2. In this state, the capacitor 1 is transferred to a solder bus or the like and soldered, but in order to prevent blowholes (pinholes) from occurring during this process, conventionally, as shown in Fig. 4, the bottom of the sealing rubber 3 is provided with steps 5, 5, which are formed by dividing a perfect circle into two and opposing each other with a pair of ventilation parts 4, 4 left between them. Reference numerals 6, 6 denote terminal insertion holes for the lead terminals 7, 7.

Usually, the outer case of this type of capacitor 1 is covered with a sleeve made of a heat-shrinkable resin film in the final step. However, in this case, the sleeve sometimes extends too deeply into the stepped portions 5, 5, as shown by the chain line in FIG. 4, and even covers the ventilation portions 4, 4. However, in order to avoid sleeves, it is necessary to
However, there is a restriction that the diameter cannot be made smaller than the distance between the lead terminal insertion holes 6, 6. Also, if you are simply concerned about preventing blowholes, it would be a good idea to provide a plurality of protruding legs at the bottom of the sealing rubber at a position where the sleeve does not cover.
In this case, when the sealing rubber is fed by an automatic component feeding device, it is not possible to align the direction of the sealing rubber. Incidentally, the vent holes 4, 4 have an alignment function that engages with a guide rail of an automatic parts supply device, thereby aligning the directions of supplied parts.
この考案は上記従来の事情に鑑みなされたもの

In order to achieve the above object, this invention includes a bottomed cylindrical case in which the capacitor element is housed, and a sealing rubber that has a pair of lead element insertion holes and is fitted into the opening of the case. , an electrolytic capacitor in which a stepped portion is formed in the sealing rubber to prevent blowholes during soldering, wherein the stepped portion is an ellipse whose long axis is arranged on a straight line connecting the pair of lead terminal insertion holes. It is characterized by having a shape and having at least one ventilation portion formed in the direction of its short axis.
上記構成によれば、通気部は短軸側に配置され
ているため、たとえ長軸側にスリーブがかかつた

According to the above configuration, since the ventilation portion is arranged on the short axis side, even if the sleeve is placed on the long axis side, it will hardly be blocked by the sleeve.
