Capacitor having electrode structure of high voltage resistance for electric vehicles

A capacitor having a high withstand voltage electrode structure for an electric vehicle, the capacitor comprising:

• a winding body wound as an inner winding, a first intermediate winding, a second intermediate winding, and an outer winding;
• a first metal electrode layer arranged on one side of the winding body;
• and
• a second metal electrode layer arranged on the other side of the winding body,
• wherein the inner winding includes a plurality of metallization films each having a heavy edge electrode formed on a surface thereof, the heavy edge electrode of one of the plurality of metallization films is arranged to be connected to the first metal electrode layer, and the heavy edge electrode of the other one of the plurality of metallization films is arranged to be connected to the second metal electrode layer and then wound,
• the first intermediate winding is formed around an outer circumferential surface of the inner winding,
• the second intermediate winding is formed around an outer circumferential surface of the first intermediate winding, the second intermediate winding including:
• a first dielectric film;
• and a first arc shield metal pattern and a second arc shield metal pattern formed on a surface of the first dielectric film to be spaced apart from each other, wherein the first arc shield metal pattern is aligned with an end of one side in the width direction of the first dielectric film and connected to the first metal electrode layer, and the second arc shield metal pattern is aligned with an end of the other side of the first dielectric film in the width direction of the first dielectric film to be spaced apart from the first arc shield metal pattern and connected to the second metal electrode layer, and
• the outer winding is formed by winding an insulating film around the outer circumferential surface of the second intermediate winding.
