Description
Technical field
The utility model relates to capacitor area, is specifically related to a kind of parallel double-sided metal polypropylene screen capacitor.
Background technology
In recent years, metallization film capacitor is widely used, and membrane capacitance adopts poly-third film to make medium, aluminium foil is made conductor, spray metal, termination solder, and loss is little, the insulation resistance height, excellent frequency and temperature characterisitic are widely used in high frequency, direct current, interchange and the impulse circuit.The metallized polypropylene film capacitor that existing aluminium foil is made electrode exists anti-electric current, voltage capability relatively poor, and defective such as volume is bigger can not satisfy small size and the high performance requirement of people to electronic product.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide the parallel double-sided metal polypropylene screen capacitor that a kind of volume is less, have good anti-electric current and voltage capability, long service life.
For achieving the above object, the utility model adopts following technical scheme:
A kind of parallel double-sided metal polypropylene screen capacitor comprises capacitor case, is positioned at capacitor main body, the termination of capacitor main body front end, the lead-in wire of capacitor case; Wherein said capacitor main body is superimposed successively by at least two double-sided metal polypropylene screen electrodes and at least two polypropylene screen dielectric layers, forms at least two electric capacity, connects with parallel way by double-sided metal polypropylene screen electrode between the electric capacity.
Double-sided metal polypropylene screen the electrode described in the utility model and polypropylene screen dielectric layer is interlaced stacks.
Be coated with the metal alloy scolder on the termination described in the utility model, preferably adopt zinc or Zinc-tin alloy.
Lead-in wire described in the utility model is connected on the termination, and itself and junction, termination scribble paraffin.
Capacitor case of the present utility model adopts plastic casing.
Than prior art, the beneficial effects of the utility model are: capacitor main body of the present utility model adopts double-sided metal polypropylene rete and the polypropylene screen dielectric layer is superimposed successively is formed by connecting with parallel way, makes the capacitor volume less and have very high anti-electric current and a proof voltage ability; Owing to adopted polypropylene screen to make medium, the utility model capacitor has good frequency characteristic, and capacitor case of the present utility model in addition adopts plastic casing, makes capacitor have good humidity resistance; Therefore utility model has little, the anti-electric current of loss and advantages such as the proof voltage ability is strong, long service life.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is the parallel double-sided metal polypropylene screen of a utility model capacitor structural scheme of mechanism;
Fig. 2 is the utility model capacitor main body structural representation.
Embodiment
As shown in Figure 1 and Figure 2, parallel double-sided metal polypropylene screen capacitor of the present utility model comprises capacitor case 1, is positioned at the termination 3 of the capacitor main body 2 and capacitor main body 2 front ends of capacitor case 1, lead-in wire 4; Wherein capacitor main body 2 is superimposed successively by at least two double-sided metal polypropylene screen electrodes 21 and two polypropylene screen dielectric layers 22, forms at least two electric capacity, is formed by connecting with parallel way between the electric capacity.Preferably, double-sided metal polypropylene rete 21 described in the utility model and polypropylene screen dielectric layer 22 interlaced stacking; Wherein double-sided metal polypropylene rete 21 and polypropylene screen dielectric layer 22 at least respectively have two-layer, form a plurality of capacitors, these capacitors connect with parallel way by double-sided metal polypropylene screen electrode 21, make capacitor have higher anti-electric current and proof voltage ability.
