Description
Technical field
The utility model relates to the improvement of capacitor, is specifically related to a kind of Novel stacked wound film capacitor.
Background technology
Film capacitor is the one in capacitor, and it is a kind of capacitor of superior performance, mainly has following characteristics: nonpolarity, insulation resistance is high, frequency response is broad, dielectric loss is little.Due to film capacitor, to have volume little, and feature capacious, so of many uses.
Film capacitor mainly makes of metallized film winding now.Metallized film on film, plates layer of metal coating be made, and the coat of metal uses as electrode.Use metallized film, decrease the volume of capacitor, easily make volume little, capacitor capacious.
Film capacitor can be divided into takeup type and stacked two kinds from processing mode, and takeup type is formed by metallized film coiling process, have the advantage of handling ease, but volume is bigger than normal.Stacked is process folded for metallized film layers, and laminated structure forms the state that plate condenser little is from level to level in parallel, and have low-loss, advantage that charging and discharging capabilities is strong, but multilayer capacitor also exists the drawback of self-healing performance difference.
The microminiaturization of film capacitor, surface-mountedization is current Main Trends of The Development and technology barriers.Along with the development of science and technology, the microminiaturized requirement of the components and parts of equipment effects on surface assembling is more and more higher, in order to make qualified capacitor on less volume, the insulating medium layer of film capacitor is more and more thinner, market there is the film being less than 3 μm, also more and more higher to the requirement of production equipment, but microminiaturized requirement can not be met completely.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of Novel stacked wound film capacitor.
The technical scheme realizing above-mentioned purpose is a kind of Novel stacked wound film capacitor, a kind of Novel stacked wound film capacitor, include insulating medium layer 1, the coat of metal 2 and insulating lacquer layer 4, described insulating medium layer 1 tow sides are affixed with the coat of metal 2, the left side of insulating medium layer 1 or right side wherein side are provided with and stay the limit 3 not paving coat of metal 2, the outside of the described coat of metal 2 is coated with insulating lacquer layer 4, the left side of the coat of metal 2 or right side wherein side are provided with japanning and stay limit 5 not to be coated with insulating lacquer layer 4, insulating medium layer 1, the coat of metal 2 and insulating lacquer layer 4 integrator, winding method is adopted to be made into film capacitor.
Described insulating lacquer layer 4 thickness is 0.5-0.9 μm.
Described insulating medium layer 1 is double-edged stays limit 3 to be respectively located at the different both sides in left side or right side, and stay on limit 3 and be coated with insulating lacquer layer 4, stay limit 3 length to be 0.1-1.0mm, described japanning stays limit 5 length to be 0.1-1.0mm.
Utilize the two-sided metallization film with enamelled coating included by the utility model by being wound into the parent capacitor body of strip, then be made into a kind of Novel stacked wound film capacitor through operations such as metal spraying, stripping and slicing, welding, moldings.
The beneficial effects of the utility model are, instead of a part of film and make medium, make the volume of capacitor less, more easily realize microminiaturization owing to have employed enamelled coating.Lamination electric capacity is made by winding method, the advantage that electric capacity is possessed film capacitor self-healing performance is good with metallized film.Thus make Novel stacked wound film capacitor be provided with low-loss, charging and discharging capabilities is strong, volume is little advantage, further improve the self-healing performance of capacitor, thus make the performance of capacitor obtain optimization.
