Claim:
1. Electric capacitor ( 1 ) having at least one capacitor coil ( 2 ), a cylindrical housing ( 6 ) that surrounds the capacitor coil ( 2 ), composed of metal, electric connectors ( 5 ), and connection lines ( 3 ) that run in the housing interior and electrically connect the capacitor coil ( 2 ) with the connectors ( 5 ), wherein at least one circumferential depression ( 7 ) is formed in the mantle of the housing ( 6 ), which depression divides the housing ( 6 ) into a first segment ( 8 ) and a second segment ( 9 ) and can be unfolded by means of excess pressure in the housing interior, wherein the first segment ( 8 ) surrounds the capacitor coil ( 2 ) and the second segment ( 9 ) carries the connectors ( 5 ), wherein the first segment ( 8 ) of the housing ( 6 ) carries an electric insulation ( 12 ) and is surrounded by this insulation on the outside, wherein the electric insulation ( 12 ) extends at most all the way to the depression ( 7 ), and wherein a covering ( 13 ) composed of an electrically insulating material is set onto the second segment ( 9 ) of the housing ( 6 ), wherein at least one connection line ( 3 ) has a planned breaking point ( 4 ), and wherein an edge region ( 14 ) of the covering ( 13 ) overlaps, at least in part, with the electric insulation ( 12 ) carried by the first segment ( 8 ), in the direction of the longitudinal axis of the housing ( 6 ).
