Therefore, the aging yield rate of the capacitor is improved, the productivity of the capacitor is improved, the quality is improved, reliability of the product is improved, and security in the ageing process is guaranteed.

Description

Capacitor arrangement

Technical field

The utility model is about a kind of capacitor arrangement, refers to especially a kind ofly first the core bag of capacitor to be carried out after burin-in process, then is sealed in the capacitor completing in aluminum hull.

Background technology

Capacitor can provide the use as power supply and electric discharge substantially, and capacitor is divided into electrolytic capacitor and non-polarized capacitor conventionally according to its function.It is quite general that the use of electrolytic capacitor can say for now.

Yet, because current electronic product is all towards lightening, high frequency, multifunction and high-reliability progress, so traditional liquid electrolytic capacitor cannot satisfy the demands, and then has towards solid electrolytic capacitor, so the demand of aluminum electrolytic capacitor development.In addition, aluminum electrolytic capacitor can be divided into again winding type electrolytic capacitor and lamination type electrolytic capacitor according to its modular construction.

Aluminum electrolytic capacitor technical development evolution, is coordinating the demand of 3C electronic product, strides forward gradually towards characteristics such as high power capacity, Low ESR, miniaturization, high frequency, high stability and environment compatibilities.Known aluminum electrolytic capacitor or solid electrolytic capacitor are combined by fuse, aluminum hull and glue lid, wherein, fuse by by positive pole aluminium foil and negative pole aluminium foil respectively nail joint in positive and negative electrode wire and electrolytic paper, reeled and formed, again fuse is impregnated in electrolyte and after forming solid electrolyte, after aluminum hull and Jiao Gai are organized to vertical encapsulation, completes.

After above-mentioned capacitor fabrication completes, need again capacitor be seen through to electric capacity ageing machine capacitor is carried out to burin-in process, but, in the process of burin-in process, because the fuse of capacitor is understood because the generation high temperature that is heated also can produce gas, make capacitor easily occur expanding, the situation that very person blasts, as can be seen here, the above-mentioned capacitor of commonly using still has many disappearances, a real non-kindhearted design, and urgently improved.

This case designer commonly uses in view of above-mentioned every shortcoming that capacitor derives, and is urgently to think to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, has has finally successfully researched and developed this part capacitor arrangement.

Utility model content

The purpose of this utility model is to provide a kind of capacitor arrangement, core in this capacitor is wrapped in the also impregnation that completes and does first to carry out burin-in process after chemical treatment, the situation that expands or explode so as to just carrying out burin-in process after avoiding core containing to put and be sealed in aluminum hull.

In order to achieve the above object, solution of the present utility model is:

A kind of capacitor arrangement, include anode fuse, one first barrier paper, the negative electrode fuse of processing once overaging and the second barrier paper once overaging, processed and sequentially superimposedly reel and form core bag again, become capacitor assembly, and capacitor assembly is placed in aluminum hull to the last open end of sealing again aluminum hull with closing component.

The core bag that described anode fuse and the superimposed coiling of negative electrode fuse form is first impregnated in and in electrolyte, carries out chemical treatment, then is held on the fixture of electric capacity aging equipment, sees through power supply to core bag continued power, completes burin-in process.

The core bag that described anode fuse and negative electrode fuse combine carries out man-to-man clamping through power supply and carries out burin-in process.

Adopt after said structure, the utility model is first by anode fuse, the first barrier paper, negative electrode fuse and the second barrier paper are sequentially superimposed reels and forms core bag again, become capacitor assembly, this anode fuse and negative electrode fuse are after the core bag that completes, just be first impregnated in to drive in electrolyte and carry out chemical treatment, carry out the core bag after chemical treatment, see through and can provide the equipment of power supply to carry out burin-in process again, after completing burin-in process, just be contained in aluminum hull, so, not only improved the production capacity of aging yield and the increase capacitor of capacitor, more promoted quality, and the reliability of product, more ensured in ageing process and can not expand, the fail safe that can not explode.

In addition, anode fuse of the present utility model and negative electrode fuse see through electric capacity ageing machine continues electric current to continue in fuse, by fuse, in open situation, carry out aging, therefore the gas that complete release produces because of ageing process in ageing process, can avoid whereby commonly seeing capacitor because gas being discharged smoothly in ageing process, and cause the capacitor expansion situation generation of blast even.

Embodiment

In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.

Refer to shown in Fig. 1 to Fig. 4, capacitor of the present utility model includes an anode fuse 1, on this anode fuse 1, be connected with a positive wire 11, one negative electrode fuse 2, on this negative electrode fuse 2, be connected with a cathode wire 21, this anode fuse 1 and negative electrode fuse 2 are by aluminium foil and at least respectively press from both sides a barrier paper and be superimposed on above to reel and form core bag, that is centre, the two poles of the earth has the first barrier paper 3 at least, after outermost is with the second barrier paper 4 and completes, first be soaked in and drive in electrolyte, the core bag of above-mentioned anode fuse 1 and negative electrode fuse 2 is carried out to chemical treatment, core double team after finishing dealing with is held on electric capacity ageing machine, see through can provide the equipment of power supply by electric current continued power to core bag, due to core be wrapped in open situation, carry out aging, therefore gas that can complete release produces because of ageing process in ageing process, the core bag completing after aging configures other capacitor assembly, and is placed in aluminum hull 5, and the last closing component 6 that sees through is again by the open end sealing of aluminum hull, and now 21 of positive wire 11 and cathode wires are piercing in closing component 6, and complete the structure of this part capacitor.

Above-mentioned capacitor anode fuse 1 and negative electrode fuse 2 are when electric capacity ageing machine carries out burin-in process, see through and can provide the equipment of power supply to clamp in mode one to one and to carry out burin-in process, aging because carrying out in open situation, so short time power supply can complete burin-in process operation fast.See through the utility model, the assembly of capacitor is processed and structure, can significantly reduce the fraction defective that capacitor produces when burin-in process, increases the production capacity of capacitor, promotes the reliability of quality and product, has especially ensured inexplosive fail safe in ageing process.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
