Method of manufacturing a capacitor with a housing having an undulated expanded portion for the event of overpressure.

摘要

A capacitor having a housing closed on one end by means of a bottom, in which housing a capacitor wrap is accommodated, said wrap having electrical connections which are fed out of the housing on the opposite end from the bottom. The housing includes a circumferential crease expandable in the axial direction of the wrap, which crease its upper side supports the wrap and on its other side a plug-like member for anchoring one end of one of the electrical connections. The plug-like member is located between the bottom and the crease and includes a hole which widens towards the bottom, which hole is filled with a synthetic resin in which one end of one connection is anchored. When an overpressure occurs in the capacitor housing, the crease is expanded and said one end of one connection is broken. The capacitor can be manufactured simply.
