Description
Technical field
The utility model relates to electric capacity production technical field, refers in particular to a kind of chip pole pin electric capacity.
Background technology
Capacitor is one of a large amount of electronic component used in electronic equipment, be widely used in circuit every straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.Along with making rapid progress of electronic information technology, the update speed goes of digital electronic goods is fast, based on the consumer electronics product volume of production and marketing sustainable growth of the products such as panel TV (LCD and PDP), notebook computer, digital camera, capacitor industry has been driven to increase.Electric capacity be divided into capacity to fix with volume-variable.But the commonly electric capacity of fixed capacity, the most common is electrochemical capacitor and ceramic disc capacitor.The basic role of capacitor is exactly charge and discharge, but the many circuit phenomenons extended out by this basic discharge and recharge effect, make capacitor have all different purposes, such as: in electro-motor, produce phase shift with it; In photoflash, produce high-octane to spark etc. with it.And in electronic circuit, capacitor purposes of different nature is especially many, this many different purposes, although also there is completely different part, because its effect is all from charge and discharge.Existing alminium electrolytic condenser is adopt the structure of one deck paper one deck paper tinsel to roll mostly, and its pin is also positive negative the two poles of the earth, and adopt this structure, electrolytic paper is easily breakdown; And the electrolytic paper, the aluminium foil that need when rolling are all longer, after making, impedance is large, and useful life is short; Capacitance guide needle contact-making surface is all adopt slab construction, bared end is then needle-like, this structure is when winding capacitance, because guide pin is tabular, and electric capacity winding is cylindric, causing easily being formed between guide pin and aluminium foil gap, easily electrolytic paper being stabbed when riveting simultaneously, thus make the capacitor fraction defective that occurs puncturing and explode when aging higher, for client's use safety hides some dangers for.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of structure is simple, fail safe is high, the chip pole pin electric capacity of long service life.
For achieving the above object, technical scheme provided by the utility model is: a kind of chip pole pin electric capacity, and described electric capacity main body is by multilayer electrolytic paper and the mutual roll-forming of aluminium foil, and main body periphery is bundled by adhesive tape; Main body one end after rolling is provided with positive and negative electrode pin, described positive and negative electrode pin is made up of flat sheet metal, one end is riveted on corresponding aluminium foil layer, other end end is provided with perforation, the riveted joint region overlay of positive and negative electrode pin and aluminium foil has packing paper, packing paper length is identical with principal length, and packing paper width is greater than riveted joint peak width; The contact-making surface of positive and negative electrode pin and aluminium foil is curved, and its radian matches with the coil diameter of capacitor aluminium foil; The positive and negative electrode foot portion being positioned at aluminium foil adopts arc rounding off.
Described electric capacity main body is made up of eight layers of electrolytic paper and four layers of aluminium foil, describedly roll employing laminated construction, outermost layer be one deck electrolytic paper, then one deck aluminium foil, more two-layer electrolytic paper, one deck aluminium foil, two-layer electrolytic paper, one deck aluminium foil, two-layer electrolytic paper, one deck aluminium foil, in the mode roll-forming of one deck electrolytic paper; Every layer of aluminium foil is equipped with a corresponding pole pin; Pole pin after rolling lines up corresponding positive and negative electrode pin row.
Described positive and negative electrode sole face is provided with several square nail joint holes, and is connected with aluminium foil by square nail joint hole.
The utility model has the advantage of:
The first, when capacitor nail joint winding makes, the Nail contacted with aluminium foil at guide pin connects position and covers the packing paper that one deck is made up of electrolytic paper, its dielectric strength is increased, and pole pin adopts cambered design, after making winding, two contact-making surfaces of pole pin are close on aluminium foil or electrolytic paper, the burr produced when decreasing and nail joint protruding by guide pin stabs the fraction defective of electrolytic paper, reduces blast and punctures fraction defective.
The second, sole face in pole adopts cambered design, and after making winding, two contact-making surfaces of pole pin are close on aluminium foil or electrolytic paper, and its contact-making surface can not occur gap again, and after winding, the superimposed degree of electric capacity is better, and winding is tightr, greatly can reduce capacity loss.
Three, adopt double-deck electrolytic paper and multilayer laminate constructions, can effectively prevent from puncturing; The aluminium foil manufactured and the length of electrolytic paper reduce one times, and impedance also reduces one times, and shorter electrolytic paper and aluminium foil can be adopted to roll, thus increase utilization rate of raw materials, save manufacturing cost.
