Abstract
An internally connected in series metallized film capacitor belongs to the technical field of capacitor, and the internally connected in series metallized film capacitor comprises lead wires, a capacitor core, a case, and filling materials, wherein the capacitor core is arranged in the case, filling materials are poured between the capacitor core and the case, the capacitor core is formed by winding the metallized film, the metallized film is internally connected in series and is formed by a metal coating and a basal lamina, and the lead wires are connected on pole plates in the capacitor core. The internally connected in series metallized film capacitor has advantages of high voltage proofness, high over current capability proofness, and the like, inside is formed by winding the metallized film composed by the metal coating and the basal lamina, the metallized film employs a internally-connected in series mode to connect, and the metallized capacitor prepared by employing the metallized film has a simplified production process, labor productivity is obviously improved, and product quality is reliablely guaranteed.
Description
Technical field
The utility model relates to the capacitor technology field, relates in particular to a kind of metallized film capacitor that adopts the internal series-connection mode to connect.
Background technology
Metallic film capacitor, its method for making be on plastic film with the very thin metal of vacuum evaporation last layer with as electrode, so can save the thickness of electrode foil, dwindle the volume of capacitor unit capacity, so it is small-sized that film capacitor is easier to make, capacitor capacious.The employed film of metallic film capacitor has poly-ethyl ester, polypropylene, Merlon etc., except convoluted, lamination-type is arranged also.The capacitor of this kenel of metallized film has a kind of so-called I my reactivation (Self Healing Action), when the minute portions of namely supposing electrode causes short circuit because electric boundary matter is fragile, cause short circuit part electrode metal on every side, can because of capacitor at that time with electrostatic energy or short circuit current, more large-arealy dissolve and evaporate and recover insulation and cause, make capacitor reply once again the effect of capacitor.
The shortcomings such as at present, existing metallized film capacitor exists complex structure, complex production process on the market, and the bearing great current ability is weak.
The utility model content
Technical problem to be solved in the utility model is to provide that a kind of production technology is simple, with low cost, the interior string metallized film capacitor of electrical getable raising.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of interior string metallized film capacitor, comprise lead-in wire, capacitor body, housing and inserts, described capacitor body is arranged on enclosure interior, be perfused with inserts between capacitor body and the housing, described capacitor body forms metallic film by the coat of metal of cascaded structure and basement membrane reels and forms, and described lead-in wire is connected on the pole plate in the capacitor body.
The described coat of metal is aluminium, silver or zinc material.
Described inserts is epoxy resin or microwax.
The beneficial effects of the utility model are: the utlity model has the advantages such as proof voltage height, anti-overcurrent capability be strong, the inner coat of metal and the basement membrane composition metallic film coiling of adopting forms, metallic film adopts the mode of internal series-connection to connect, the metallized capacitor that utilizes this metallic film to make, production technology is simplified, labor productivity obviously improves, and product quality obtains reliable guarantee.
