Abstract

A capacitor comprises a metal case containing a capacitor element together with driving electrolyte and having an inner bottom face joined to one electrode and a terminal plate sealing the opening of the metal case by joining the other electrode of the capacitor element to the inner surface. The terminal plate is provided with a pressure regulation valve also serving as a hole for injection the driving electrolyte. The pressure regulation valve comprises an elastic ring member, a gas permeation sheet joined to the upper surface thereof, a rubber valve element arranged thereon, and a cap for containing them and holding the valve element in a compressed state. Since the elastic member is press fitted in a wall portion provided on the terminal plate, leakage of the driving electrolyte is eliminated and a highly reliable capacitor can be produced.

Description

Capacitor
Technical field
The present invention relates to the capacitor that in the regeneration of various electronic equipments or hybrid vehicle or electric power storage etc., uses.
Background technology
Figure 66 is the profile of the structure of the existing capacitor of expression.Figure 67 is the profile that expression is arranged on the structure of the pressure-regulating valve in the existing capacitor.Among Figure 66 and Figure 67, in capacitor element 20, be formed with hollow bulb 20a.This capacitor element 20 constitutes in the following manner: pair of positive and negative is staggered to opposite direction each other, make separator (separator) between this is to positive and negative electrode, this reel again to positive and negative electrode, and described pair of positive and negative forms polarizable electrode layer (all not shown) on the collector body that is made of aluminium foil.And described capacitor element 20 constitutes: can take out anode and negative electrode respectively from its both ends of the surface (being above-below direction Figure 66).
Metal shell 21 is housings of the tubular that the end is arranged of aluminum, wherein takes in capacitor element 20 and not shown driving electrolytic solution in the lump.Cathode terminal 21a is the outside terminal for connecting that is arranged on integratedly on these metal shell 21 outer bottoms.Projection 21b is arranged on the inner bottom surface integratedly in the mode in the hollow bulb 20a that is embedded into capacitor element 20.This projection 21b is embedded in the hollow bulb 20a of capacitor element 20, with the end face of the cathode side that inserts the capacitor element 20 in the metal shell 21 by modes such as laser welding machinery and electrically be bonded on the inner bottom surface of metal shell 21.
Hush panel 22 is aluminums.Anode terminal 22a is arranged on the face side of this hush panel 22 integratedly.Projection 22b is embedded in the hollow bulb 20a of capacitor element 20.The end face of the anode-side of capacitor element 20, be engaged to the inner face of hush panel 22 by modes such as laser welding, thereby mechanically, electrically be connected the inner face of hush panel 22, and, on the periphery of this hush panel 22, mode with the peristome that is involved in metal shell 21 is processed (generally being called crimping processing), thereby with the end face seal of the anode-side of capacitor element 20.
And, pressure-regulating valve 23 is equipped with gas permeability parts 24 and occlusor 25 on the 22c of electrolyte injecting hole portion, covered and fixed ventilation parts 24 and occlusor 25 by the metal cap 26 that has with the 26a of hole portion of external communications, occlusor 25 applies power to the direction of obturation always.Fixedly realizing in the following manner of this metal cap 26: the circular protuberance 22d that will set in advance on hush panel 22 in the mode of surrounding around the electrolyte injecting hole 22c of portion carries out ca(u)lk (caulking) processing etc., makes circular protuberance 22d distortion and is pressed on the metal cap 26.
And pressure-regulating valve 23 is, when the internal pressure of capacitor during more than or equal to the pressure of regulation, is used for making pressure to be discharged into the outside pressure-regulating valve of recovery type certainly.Therefore, the inner gas release that produces of capacitor can be arrived the outside, thereby prevent that the capacitor pressure inside from rising.And after action, pressure-regulating valve 23 can return to the preceding state of action to keep the air-tightness of capacitor inside.So, when promptly box lunch causes pressure to rise because of the inner generation of capacitor gas, also can keep the characteristic of capacitor, and can not cause the outward appearance of capacitor to occur unusual.
Pressure-regulating valve 23 can prevent that driving electrolytic solution from seeing through.And, be equipped with gas permeability parts 24 owing to being close at pressure-regulating valve 23, so do not have because of driving electrolytic solution attached to the such situation of function of damaging pressure-regulating valve 23 on the occlusor 25, described gas permeability parts 24 are to be made of the material that can make the inner gas permeation that produces of capacitor to the outside.And pressure-regulating valve 23 can prevent that driving electrolytic solution from leaking into the capacitor outside.
The existing capacitor of Gou Chenging makes pressure-regulating valve 23 fixed configurations on the 22c of electrolyte injecting hole portion in the above described manner, thereby has reduced the position that driving electrolytic solution might be leaked.In addition, as the relevant prior art documentation ﹠ info of the invention of application case therewith, for example known have the Japan Patent spy to open the 2004-134632 communique.
Yet, in described existing capacitor, be by making pressure-regulating valve 23 fixed configurations on the 22c of electrolyte injecting hole portion, reduce the leakage of driving electrolytic solution, but gas permeability parts 24 do not engage with hush panel 22.Therefore, driving electrolytic solution boundary leakage from then on easily.For head it off, can gas permeability parts 24 be engaged with hush panel 22 by modes such as bonding or welding, but because the relation of both physical characteristics of materials etc. engages very difficulty.
Summary of the invention
The present invention solves this existing problem, provides a kind of driving electrolytic solution can not leak and can realize the capacitor of good reliability.
Capacitor of the present invention comprises: capacitor element, it constitutes in the following manner, promptly, make separator between pair of positive and negative and reel this to positive and negative electrode, and this positive and negative electrode is positioned at opposite direction each other, and described pair of positive and negative is formed with polarizable electrode layer on the collector body that is made of metal forming; The metal shell that the tubular at the end is arranged, it takes in capacitor element and driving electrolytic solution in the lump, and one of them electrode of junction capacitance device element on its inner bottom surface; And terminal board, the peristome of another electrode of junction capacitance device element and sealing metal housing on its inner face, and, on described terminal board, pressure-regulating valve is set, this pressure-regulating valve double as is for injecting the hole portion of portion of driving electrolytic solution, and pressure-regulating valve comprises: the elastomeric element of ring-type; The gas permeability thin slice that engages to cover the mode above the elastomeric element; Be provided in the rubber system valve body on the gas permeability thin slice; And valve body remained on the cap body of compressive state, and, elastomeric element is pressed into the annular wall portion of the upper face side of the hole portion periphery that is located at terminal board.
According to such structure, engage the gas permeability thin slice in the top mode that covers the ring-type elastomeric element, so that described elastomeric element is close to hole portion, utilize this structure, can realize that driving electrolytic solution can not leak and have the capacitor of good reliability.
