Reinforced capacitor housing of fluid material especially aluminium

摘要

The housing has a base (14) with a rupture point (26) located in the apex region of the base. This is arranged in a diametrically running beading (18) and extends inwardly from the cup exterior. The rupture point (26) includes a slit type weakened section of the wall. The beading (18) extends over the cup base (14) which is flat over its inner surface (24) towards the inside of the cup. At least one further beading (20,22) attached from outside is spaced from the beading (18) containing the rupture point (16). This extends over the base inner surface (24). Two further beadings (20) may be arranged parallel to the first beading (18) on both sides. Alternatively, two beadings (22) may be arranged on both sides of the first beading perpendicular or at an angle to the first one (18).
