The present disclosure relates to a wound capacitor package structure and a wound assembly thereof, and more particularly to a wound capacitor package structure having conductive foils of unequal width and a wound assembly thereof.
Various applications of capacitors include home appliances, computer motherboards and peripherals, power supplies, communication products and automobiles. The capacitors such as winding capacitors are mainly used to provide the functions of filtering, bypassing, rectifying, coupling, blocking or transforming. The winding capacitor includes a capacitor core, a casing, and a sealing cover. The capacitor core has an anode foil coupled to an anode terminal, a cathode foil coupled to a cathode terminal, a separator, and an electrolyte layer. The anode foil, the cathode foil and the separator are rolled together. The separator is disposed between the anode foil and the cathode foil. The electrolyte layer is formed between the anode foil and the cathode foil. The casing has an opening for receiving the capacitor core. The sealing cover can used to seal the casing, and the anode terminal and the cathode terminal can pass through a through hole of the sealing cover. A given space is provided between the sealing cover and the capacitor core. A stopper for securing the space is provided on at least one of the anode terminal and the cathode terminal.
One aspect of the present disclosure relates to a wound capacitor package structure having conductive foils of unequal width and a wound assembly thereof.
One of the embodiments of the present disclosure provides a wound capacitor package structure having conductive foils of unequal width, comprising a wound assembly, a package assembly, and a conductive assembly. The wound assembly includes a wound positive conductive foil, a wound negative conductive foil, and two wound separator papers. One of the two wound separator papers is disposed between the wound positive conductive foil and the wound negative conductive foil, and one of the wound positive conductive foil and the wound negative conductive foil is disposed between the two wound separator papers. The package assembly is used for enclosing the wound assembly. The conductive assembly includes a first conductive pin electrically contacting the wound positive conductive foil and a second conductive pin electrically contacting the wound negative conductive foil. The first conductive pin has a first embedded portion enclosed by the package assembly and a first exposed portion exposed out of the package assembly, and the second conductive pin has a second embedded portion enclosed by the package assembly and a second exposed portion exposed out of the package assembly. The wound positive conductive foil has a first predetermined width, the wound negative conductive foil has a second predetermined width, each of the two wound separator papers has a third predetermined width, and the first predetermined width of the wound positive conductive foil and the second predetermined width of the wound negative conductive foil are different.
Another one of the embodiments of the present disclosure provides a wound capacitor package structure having conductive foils of unequal width, comprising a wound assembly, a package assembly, and a conductive assembly. The wound assembly includes a wound positive conductive foil and a wound negative conductive foil. The package assembly is used for enclosing the wound assembly. The conductive assembly includes a first conductive pin electrically contacting the wound positive conductive foil and a second conductive pin electrically contacting the wound negative conductive foil. The wound positive conductive foil has a first wound outer side, the wound negative conductive foil has a first wound outer side, the first wound outer side of the wound positive conductive foil is correspondingly adjacent to the first wound outer side of the wound negative conductive foil, and the first wound outer side of the wound positive conductive foil and the first wound outer side of the wound negative conductive foil are arranged in a staggered arrangement and separated from each other by a first vertical offset distance.
Yet another one of the embodiments of the present disclosure provides a wound assembly, comprising a wound positive conductive foil, a wound negative conductive foil, and two wound separator papers. The wound positive conductive foil has a first predetermined width, the wound negative conductive foil has a second predetermined width, each of the two wound separator papers has a third predetermined width, and the first predetermined width of the wound positive conductive foil and the second predetermined width of the wound negative conductive foil are different.
Therefore, the distance between the wound outer side of the wound positive conductive foil and the wound outer side of the wound negative conductive foil can be increased by matching the features of “the first predetermined width of the wound positive conductive foil and the second predetermined width of the wound negative conductive foil are different” or “the first wound outer side of the wound positive conductive foil and the first wound outer side of the wound negative conductive foil are arranged in a staggered arrangement and separated from each other by a first vertical offset distance”, so that the prevent disclosure not only can avoid causing a short circuit or an electrical failure between the wound positive conductive foil and the wound negative conductive foil due to arc discharge, but also can increase the electrical performance of the wound capacitor package structure.
