Description
Technical field
The utility model relates to electric elements, particularly to the improvement of capacitor.
Background technology
Existing high-frequency resonant capacitor generally can adopt aluminium electrolytic capacitor, discloses a kind of thin film aluminum electrolytic capacitor as Chinese patent ZL200820181137.1, and this patented technology can reduce the pollution of electrolytic capacitor in manufacturing process.
At present, comprise above-mentioned high frequency capacitor, its capacitor body is to be reeled and made by metal light film, the aluminium foil trilaminate material aluminized in light film, surface.Present high-frequency resonant capacitor ubiquity volume is big, cost is high, inefficient shortcoming.
The utility model content
The purpose of this utility model provides a kind of novel high-frequency resonant capacitor, and the volume that the utility model has solved present like product existence is big, cost is high, inefficient problem.
A kind of novel high-frequency resonant capacitor of the present utility model is made of electrode, shell, capacitor body; Capacitor body is the cylindrical structural that layer material is reeled.The winding-structure that described capacitor body is made of double-edge aluminium film, intermediately remained border one side zinc coating aluminium film; The mid portion of double-edge aluminium film has aluminium coated, and double-edge aluminium film both sides are aluminium coateds not; The both sides of intermediately remained border one side zinc coating aluminium film are zinc-plated aluminium laminations, and the centre of intermediately remained border one side zinc coating aluminium film is the light film that does not plate.
Further, a kind of novel high-frequency resonant capacitor of the present utility model can also have following characteristics, and there is gilding layer at the two ends of capacitor body.
A kind of novel high-frequency resonant capacitor of the present utility model has advantage: 1, volume is little, consumptive material is few, cost is low, and the high advantage of efficient; And because of its extraction electrode is the metallized film structure, self-healing property makes withstand voltage improving well.2, this novel high-frequency electrode for capacitors is drawn employing is evaporation thickening zinc-aluminium plating district and the contacting of gilding layer, and this structure is much better than the contact that the AM aluminum metallization film has gilding layer; It can bear bigger rush of current, and the course of processing is difficult for producing waste product, the raising product percent of pass.
Description of drawings

Fig. 2 is the structural representation of capacitor body among Fig. 1;
Fig. 3 is the expanded view of the utility model capacitor body.
Embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.
Consult Fig. 1-2, a kind of novel high-frequency resonant capacitor is made of electrode 1, shell 2, capacitor body 3; Capacitor body 3 are layer 2-3 material webs around cylindrical structural, there is gilding layer 4 at the two ends of capacitor body 3.
Consult Fig. 3, the winding-structure that described capacitor body 3 is made of double-edge aluminium film 6, intermediately remained border one side zinc coating aluminium film 9; The mid portion of double-edge aluminium film 6 has aluminium coated 8, and double-edge aluminium film 6 both sides are aluminium coateds 7 not; The both sides of intermediately remained border one side zinc coating aluminium film 9 are zinc-plated aluminium lamination 9-1, and the centre of intermediately remained border one side zinc coating aluminium film 9 is the light film 9-2 that do not plate.
Design feature: 1, winding-structure seeing left image, double-edge aluminium film is reeled with intermediately remained border zinc-aluminium film (annotate: two membranes coating direction is the same, all inwardly) no-induction.To annotate: it rises/and rolling cleans for burning film.2, film dimensions: double-edge aluminium film width is B (common have 22,28mm), (the coating width B 1 of its width C=B+2mm) (common have 19,25mm) stays hem width degree B2 (common have 1.5,2mm) intermediately remained border one side zinc coating aluminium film coating width B 3 (common have 10.5,13.5mm) the wrong bright dipping membrane portions of intermediately remained border width B 5 (3-4mm) intermediately remained border zinc-aluminium film width B 4 (B4=1mm) 3, B5 width to be fixed as 3-4mm to intermediately remained border one side zinc coating aluminium film width C, B4 is fixed as 1mm, and other size can correspondingly be adjusted.4, two edges thicken zinc-plated aluminium lamination width B 6 (that common is 3-5mm).
The utility model is made medium with polypropylene film, and metalized film is made the electrode winding-structure, and the no-induction winding-structure, is sealed material, stepped and to draw the adhesive tape epoxy encapsulation available shell epoxy encapsulation.Make the zinc-plated constructed of aluminium for the thickening of intermediately remained border two edges of the metalized film employing of electrode.
Effect of the present utility model: 1, existing high-frequency resonant capacitor is compared, and this novel high-frequency resonant capacitor has that volume is little, cost is than the former is low by about 15%, efficient is high advantage.2, this novel high-frequency resonant capacitor has advantages such as steady quality, withstand voltage height, overcurrent be big, for condition has been created in larger capacity (1.2uF/1200V, 1uF/1600V) miniaturization.This electric capacity can bear bigger rush of current.
