Abstract

The invention discloses a coiling-type solid electrolytic capacitor packaging structure using a lead rack comprising a coiling-type solid electrolytic capacitor, a packaging body, and a conductive unit. The coiling-type solid electrolytic capacitor is provided with a coiling body, an anode conductive pin, and a cathode conductive pin. An end of the anode conductive pin is provided with a cutting surface, and an end of the cathode conductive pin is provided with a grinding surface. The coiling-type capacitor is wrapped by the packaging body. the conductive unit comprises an anode conductive terminal electrically connected with the anode conductive pin and a cathode conductive terminal electrically connected with the cathode conductive pin. The anode conductive terminal is provided with a first inwardly-buried part disposed in the packaging body in a wrapped manner and a first exposed part exposed out of the packaging body. The cathode conductive terminal is provided with a second inwardly-buried part disposed in the packaging body in a wrapped manner and a second exposed part exposed out of the packaging body. The first exposed part and the second exposed part can extend along the outer surface of the packaging body.

Description

technical field [0001] The present invention relates to a capacitor packaging structure and a manufacturing method thereof, especially to a winding type solid electrolytic capacitor packaging structure using a lead frame and a manufacturing method thereof. Background technique [0002] A winding solid electrolytic capacitor includes: a capacitor assembly, a housing member, and a sealing member. In the capacitor assembly, an anode foil connected to an anode terminal and a cathode foil connected to a cathode terminal are wound through a separator, and an electrolyte layer is formed between the anode foil and the cathode foil. The receiving member has an opening and can accommodate the capacitor assembly. The sealing member has a through hole through which the anode terminal and the cathode terminal can penetrate, and an opening part which can seal the receiving member. In addition, there is a predetermined gap between the sealing member and the capacitor unit, and at least o...
