Sealing member for a capacitor and method for manufacturing a capacitor
View Patent ↗A sealing member for a capacitor is formed of an elastic material, and has a circular cylindrical shape extending along an axial direction. The sectional view perpendicular to the axial direction shows a circular shape. Further, a pair of through-holes is formed parallel to the axial direction. The shape of each through-hole in the sectional view perpendicular to the axial direction of the sealing member is composed of a first arc and a second arc. The first arc protrudes toward the circumference of the sealing member. The second arc protrudes toward the center of the sealing member and has a curvature smaller than that of the first arc.
1. A sealing member for a capacitor comprising:
an elastic material having a circular cylindrical shape extending along an axial direction, and a sectional view thereof perpendicular to the axial direction showing a circular shape,
wherein a pair of through-holes is formed in the sealing member parallel to the axial direction, and
a shape of each of the pair of through-holes in the sectional view perpendicular to the axial direction is composed of a first arc and a second arc, the first arc protruding toward a circumference of the circular shape, the second arc protruding toward a center of the circular shape and having a curvature smaller than that of the first arc.
