[Prior Art] At present, electrolytic capacitors are distinguished by solid electrolytic capacitors and liquid electrolytic capacitors. The electrolytic capacitors mainly include a capacitor element, and the outer casing is disposed outside the capacitor element. The capacitor element has a cathode and an anode. And the winding portion of the electrolyte disposed therebetween is sealed in the insulating case and has two pins extending through the bottom surface of the insulating case for external connection. In the construction of the electrolytic capacitors described above, the conventional liquid or solid electrolytic appliances are all made of aluminum and other metal casings, but the metal casings such as aluminum must be sealed with a capacitor of a considerable thickness to seal the capacitors in the casing. There is a problem that the electrolytic capacitor has a large volume, which is not conducive to the thin and light short development trend of 'L'. Therefore, the electrolytic capacitor has been developed with an outer casing made of insulating material, so that the electrolytic capacitor can further reduce the volume. . However, the existing electrolytic capacitors, whether they are packaged in a metal case or an insulating case, must be further bent into an L shape when the external leads can be soldered to the board by surface mount technology. For flat bending and other processing, the pins will cause stress damage to the electric grain or pin during the bending and flattening process, which affects the reliability of the electrolytic capacitor, and the electrolytic capacitor is in the process of manufacture. The process of heating at a high temperature easily causes the solder layer of the surface of the foot Dgn ± _ to be carbonized and destroyed, and the pin which reduces the pin has a narrow pin shape of the electrolytic capacitor, and can provide soldering and area. It is too small, and the pin bent into an L shape is susceptible to an external force, and the electrolytic capacitor is soldered to the circuit board, and the L-shaped pins are only fixed at the ends, and the ends are free. There is a good problem. SUMMARY OF THE INVENTION .

[Simplified description of the drawing]: One figure is an exploded perspective view of the electrolytic capacitor of the present invention having a preferred embodiment. The first-second diagram is a schematic diagram of the first embodiment of the electrolytic capacitor shown in the first figure. The first diagram of the system of Ji Jijia's example is a schematic view of the three-dimensional appearance after the electrolysis shown in the first figure. The fourth figure is the section of the electrolytic capacitor type electrolytic capacitor. (4) Figure β ° ° I is the best example. The fifth figure is shown in the first figure. The edge shell is filled with € & Electro-grid - preferred embodiment in the extinction Is a schematic cross-sectional view of a sixth FIG patterns based electroless present invention. The second preferred are azelaic y °° good having a plurality of capacitor element 1 son "bottom perspective exploded view of the embodiment. The seventh figure is a bottom view of the bottom view, and the second embodiment of the present invention is combined with the second preferred embodiment. The inventive electrolytic capacitor has a single capacitance element and a schematic view. - 铋 实施 实施 实施 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 第九 θ θ θ θ θ θ θ θ θ θ θ θ θ θ For example, the three-dimensional view of the present invention is a schematic diagram of the electrolytic capacitor of the present invention having a single capacitance element and the s" electric glutinous element having four internal pins.
