  • Capacitor with fixing bus bar and capacitor case including rib for securing strength of the capacitor
    Patent number: 12087508
    Abstract: A capacitor includes: a capacitor element; a pair of bus bars; a capacitor case; and a sealing member. The capacitor element includes a pair of electrode surfaces. Each of the pair of bus bars is connected to a corresponding one of the pair of electrode surfaces. The capacitor element and the pair of bus bars are arranged in the capacitor case. The sealing member is charged in the capacitor case. The sealing member seals the capacitor element. The capacitor case includes a rib extended from a part of the capacitor case to an inside of the capacitor case. One of the pair of bus bars serves as a fixing bus bar, the fixing bus bar includes a direct fixing portion to be directly fixed to the rib.

  • Capacitor
    Patent number: 12062496
    Abstract: A capacitor includes a capacitor element, a pair of bus bars, and an insulating member. The capacitor element includes a positive electrode surface and a negative electrode surface. The pair of bus bars includes a positive electrode bus bar that is connected to the positive electrode surface of the capacitor element and a negative electrode bus bar that is connected to the negative electrode surface, A plate-shaped insulating member is disposed between the positive electrode bus bar and the negative electrode surface. A part of the insulating member is inserted into a bus bar through-hole provided in the positive electrode bus bar.
