US Patent 4283750: Capacitor having a housing provided with a crease…
US 4283750 · granted 1981-08-11
Abstract
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.

Claim 1
A capacitor having a housing which is closed on one end by means of a bottom and which accommodates a capacitor wrap, said wrap being provided with electrical connectionswhich are fed out of the housing through the end opposite the bottom, said housing having a circumferential crease which is expandable in the axial direction of the wrap and which crease, when expanded, on its upper side supports the wrap and on itslower side a plug-like member for anchoring one end of one of said electrical connections of the wrap, characterized in that the plug-like member is located between the expandable crease and the bottom of the housing and includes a hole which widenstowards the bottom of said housing, which hole is filled with a synthetic resin in which one end of one of said electrical connections is anchored by means of a loop in said end.
