Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of capacitor core group.
With reference to Fig. 2, Fig. 3 and Fig. 4, Fig. 2 is the inside deployed configuration schematic diagram of the utility model preferred embodiment, Fig. 3 is positive electrode paper tinsel 100 and electrolysis ply of paper 300 in Fig. 2, lead chaff 400 and coordinate generalized section, Fig. 4 is negative electrode foil 200 and electrolysis ply of paper 300 in Fig. 2, lead chaff 400, interleaving paper 500 coordinates generalized section, in the utility model embodiment, capacitor core group is described for two-layer positive electrode paper tinsel 100 and two-layer negative electrode foil 200, the positive electrode paper tinsel 100 of three layers and the above number of plies, negative electrode foil 200 is all with reference to the description of following examples, do not repeat one by one at this.This capacitor core group comprises two-layer positive electrode paper tinsel 100, two-layer negative electrode foil 200 and holds the electrolysis ply of paper 300 of described positive electrode paper tinsel 100 and negative electrode foil 200, above-mentioned two-layer positive electrode paper tinsel 100 forms two electrode units with two-layer negative electrode foil 200, and polarity between two electrode units is contrary, thus the capacitor core group after expansion is followed successively by positive electrode paper tinsel 100, electrolysis ply of paper 300, negative electrode foil 200, electrolysis ply of paper 300, positive electrode paper tinsel 100, electrolysis ply of paper 300, negative electrode foil 200, electrolysis ply of paper 300 from top to bottom.When making the capacitor of same specifications parameter, its positive electrode paper tinsel 100 is constant with the total length of negative electrode foil 200, namely dielectric gross area is constant, reeled by multilayer positive electrode paper tinsel 100 and multilayer negative electrode foil 200 intersecting and arrange, replace original individual layer positive electrode paper tinsel 100 and individual layer negative electrode foil 200 reels, the time of the winding process of whole capacitor core group is shortened greatly, improves the production efficiency of whole capacitor.
Particularly, in the winding process of capacitor core group, reel after positive electrode paper tinsel 100, negative electrode foil 200 can being alignd one by one, also positive electrode paper tinsel 100 first can be reeled, after the length that reels (this length is determined according to the capacitance of concrete electric capacity and the size of electric capacity), again negative electrode foil 200 is stacked on positive electrode paper tinsel 100 and reels, because the price of negative electrode foil 200 is slightly expensive relative to the price of positive electrode paper tinsel 100, when later a kind of mode reels, the use amount of negative electrode foil 200 can be saved, reduce the production cost of capacitor core group further.
Further, described capacitor core group also comprises being riveted on, and positive electrode paper tinsel 100 and negative electrode foil 200 lead chaff 400, described in lead chaff 400 with the riveting method of described negative electrode foil 200 be cold riveting.
Leading chaff 400 by riveting on positive electrode paper tinsel 100 with negative electrode foil 200, extracting, so that the making of subsequent capacitance device for the electrode after positive electrode paper tinsel 100 and negative electrode foil 200 have been reeled.And because negative electrode foil 200 is soft, adopt cold riveting to fix and negative electrode foil 200 can not be made to crack, and more firm after riveted joint.
Further, lead chaff 400 described in and be coated with interleaving paper 500 with riveted joint place of described negative electrode foil 200.
Lead after chaff 400 riveted with negative electrode foil 200, its riveted joint place is uneven, thus the field intensity different sizes of riveted joint place on negative electrode foil 200, powerful after certain numerical value then and there, capacitor easily lost efficacy; Therefore, cover interleaving paper 500 in riveted joint place, make the field intensity on negative electrode foil 200 unified, the useful life of capacitor and anti-ripple ability are improved, the user demand of welding machine, ups power and frequency converter can be met better.
The utility model also provides a kind of capacitor, and this capacitor comprises capacitor core group, and the detailed construction of described capacitor core group, with reference to the description of above-described embodiment, does not repeat one by one at this.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
