Publication number: 20110149472Abstract: There is provided a method of connecting busbars for a capacitor and a product manufactured by the same method, whereby the inductance of the capacitor is decreased and thus the amount of heat generated in the capacitor is decreased to improve the temperature characteristics and electrical characteristics of the capacitor and the reliability of the quality of the capacitor, to consistently improve the insulation between the busbars having different polarity, and to maintain the insulation between the busbars in severe environments. The method of connecting busbars for a capacitor is characterized by coating at least parts of an N-pole busbar and a P-pole busbar, each of which has different polarity, with an insulating material; exposing parts of the N-pole and P-pole busbars outside an outer case so as to form a terminal to be connected to an other component; and connecting the N-pole busbar to the P-pole busbar in a manner that at least parts of the N-pole and P-pole is busbars overlap each other.Type: ApplicationFiled: December 21, 2009Publication date: June 23, 2011Applicant: NUINTEK CO., LTD.Inventors: Chang-Hoon YANG, Dae-Jin Park, Yong-Won Jun
