Abstract

The invention relates to an electrolytic capacitor with an external connected pin, which comprises a shell, at least one capacitor element and a plurality of external pins. The shell comprises a hollow plastic shell seat and a seal cover which is sealed on the plastic shell seat and seals the capacitor element inside; the capacitor element is provided with a plurality of small sections of internalpins which pass through the bottom of the shell; the external pin comprises a plate pin body and a connecting part at one side of the pin body; and the connecting part is aligned and connected with the internal pins through conducting perforations on the connecting part, and embedded and fixedly combined with a fixedly-connected convex part corresponding to the plastic shell seat through fixedly-connected concave parts of fixed parts at two sides of the pin body. Therefore, the external pins of large area can provide good welding stability when the electrolytic capacitor is adhered to the surface.

Description

technical field [0001] The invention relates to an electrolytic capacitor, in particular to a structural design of an electrolytic capacitor with external pins. Background technique [0002] At present, the existing known electrolytic capacitors, no matter whether they are packaged with a metal shell or an insulating material shell, in order to make the external pins solderable to the circuit board by surface mount technology, the pins must be further bent into an L-shape or made Flattening into sheets and then bending processing, because these pins will cause stress damage to the capacitor elements or pins in the process of bending and flattening, which will affect the reliability of the electrolytic capacitor. In addition, the high-temperature heating process used in the manufacture of the electrolytic capacitor tends to carbonize and destroy the solder layer on the surface of the pins, thereby reducing the solderability of the pins. [0003] Furthermore, the pin shape of...
