Claims

[Claims for Utility Model Registration] (1) A metallized film in which an electrode is formed by providing an insulating margin at the edge in the width direction of the film, and an insulating groove is provided in at least a part of the vapor-deposited electrode in the width direction of the film. In a dry-type metallized film capacitor, which is formed by stacking and winding the insulating margins so that the insulation margins face each other, forming electrode lead-out parts at both ends to form a capacitor element, and encasing the element,
A dry metallized film capacitor, characterized in that the capacitor element is formed by heat treatment, and when the dielectric film partially breaks down, vapor-deposited electrodes having insulating grooves are scattered in the length direction near the ends of the insulating margins. (2) The insulating groove is formed across the width direction of the metallized film, and the vapor-deposited electrode is completely separated into a plurality of pieces, as described in claim 1 of the utility model registration. Dry metallized film capacitor. (3) A plurality of the insulating grooves are formed in the width direction of the metallized film leaving a part of the vapor deposited metal, and the plurality of vapor deposited electrodes are connected to each other by the remaining vapor deposited metal. Scope of Utility Model Registration Claims ``Dry-type metallized film capacitor according to item 1.'' (4) The distance between the metal sprayed side end of the metallized film and the insulation margin side end of the opposing metallized film is within the range of 0.1 to 2.0 mm. A dry metallized film capacitor according to claim 2 or 3 of the utility model registration claim.
