Title: Capacitor top closing disc - has elasticised gasket seal around outer edge and terminal connections onto which can presses
IPC: H01G9/10
Filed: 1979-01-27
Abstract: Top plate disc is for closing the can of a capacitor. The disc has facility for the capacitor connecting wires to be fed through sealing grommets and for the lip of the can to be bent over onto a sealing gasket around the perimeter of the top disc. The synthetic material, e.g. plastic, sealing disc has a gasket around it's outer edge which rests on a shoulder of the disc. The connecting wirs to the capacitor are fed through gaskets also provided in the top disc. The elasticised material used for the gaskets is so firmly attached to the sealing disc that total destruction is the only method of removal. The top lip of the capacitor can is bent over to press into the outer gasket and form a tight seal around the top of the capacitor. Therefore during the assembly the gasket is outwards.
