Abstract:
A method of making an electrolytic capacitor comprising:providing a capacitor case defining an interior case chamber, the case having a case side wall extending to a side wall upper opening edge, providing a cover adapted to be sealed against the side wall upper opening edge to enclose the interior case chamber, forming an electrode stack assembly, the electrode stack further comprising a plurality of capacitor layers stacked in registration upon one another, each capacitor layer comprising a cathode layer having a cathode tab, an anode sub-assembly comprising at least one anode layer having an anode tab, and a separator layer located between adjacent anode and cathode layers, whereby all adjacent cathode layers and anode layers of the stack are electrically insulated from one another by a separator layer, disposing the electrode stack assembly within the interior case chamber; electrically connecting the anode tabs to an anode terminal pin; extending the anode terminal pin through an anode opening of the capacitor case side wall providing an anode connection terminal at the exterior of said case in relation to an external encapsulation area of the case side wall; electrically connecting the cathode tabs to a cathode terminal pin; extending the cathode terminal pin to one of the capacitor case or through a cathode opening of the capacitor case side wall providing a cathode connection terminal in relation to said external encapsulation area; attaching a connector assembly comprising a wiring harness having lead wires with exposed ends to said anode and cathode connection terminals thereby making electrical connection with said anode and cathode tabs and forming a capacitor assembly; and forming a connector block comprising an epoxy droplet adhered to the encapsulation area of the capacitor side wall surrounding and encapsulating the anode and cathode connection terminals and the attached exposed ends of the wiring harness lead wires.
