Embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
Fig. 1 illustrates the explosion prevention capacitor formula battery in the utility model one embodiment.This explosion prevention capacitor formula battery comprise metal shell 1, with the close-fitting block 2 of metal shell 1, metal shell 1 is formed for accommodating battery core and electrolytical containing cavity 5 between 2 with blocking a shot; Block 2 is provided with explosion-proof impression 4.Particularly, metal shell 1 comprises the sidewall 12 of circular diapire 11 and tubulose, and diapire 11 is one-body molded with sidewall 12, and on sidewall 12, is provided with the fastening assembly 3 for fastening block 2, to guarantee metal shell 1 and the compactness of blocking a shot and being connected between 2; Block 2 is provided with explosion-proof impression 4, with avoid overvoltage, overcurrent, aging, dispel the heat in the situation such as bad, the gas that the electrolyte in containing cavity 5 produces breaks metal shell 1, produces " the quick-fried slurry of electric capacity " phenomenon.Understandably, metal shell 1 can be aluminum hull, can be also the shell that other other metals that do not react in electrolyte form.
Explosion-proof impression 4 comprises that being arranged on block 2 one sides away from containing cavity 5 is provided with trapezoidal groove wide at the top and narrow at the bottom.Particularly, explosion-proof impression 4 is the settings of " T " font (as shown in Figure 2), " ten " font, " rice " font or other shapes; When condenser type battery is during in use due to overvoltage, overcurrent, the gas that aging, heat radiation poor prognostic cause produces, explosion-proof impression 4 upwards deforms, and discharge gases from explosion-proof impression 4, to prevent that capacitive battery pond from blasting, and then cause potential safety hazard.
More specifically, for guaranteeing the normalization of explosion prevention capacitor formula battery production, during production, making the diameter of metal shell 1 diapire 11 and block 2 is 7.95～8.05mm, and the thickness of diapire 11 is 0.37～0.43mm, and the thickness of block 2 is 0.40～0.70mm; The height of sidewall 12 is 50.4～50.6mm, and the thickness of sidewall 12 is 0.22～0.28mm.The length of trapezoidal groove upper base is 0.2～0.4mm, and the length of going to the bottom is 0.1～0.2mm, is highly 0.19～0.38mm.
Fastening assembly 3 comprise be arranged on sidewall 12 openends inwardly protruded for avoid blocking a shot 2 seal mouth rings that come off 31 and be arranged on seal mouth ring 31 and diapire 11 between inwardly protruded for avoiding 2 spacing rings that move to diapire 11 32 of blocking a shot; The consistency of thickness of the distance between seal mouth ring 31 and spacing ring 32 and block 2.Understandably, fastening assembly 3 can effectively guarantee metal shell 1 and block 2 compactnesses that are connected.
Particularly, in this explosion prevention capacitor formula battery production process, use decompressor to stamp out respectively diapire 11 and the integrated metal shell 1 of sidewall 12 and the block 2 that is provided with explosion-proof impression 4; On metal shell 1, fill battery core and electrolyte, and place at the openend of metal shell 1 block 2 that is provided with explosion-proof impression 4; Adopt rolling closing device along the sidewall 12 of metal shell 1 circumferentially roll out seal mouth ring 31 and spacing ring 32, to fix block 2, complete the manufacturing of explosion prevention capacitor formula battery.This explosion prevention capacitor formula battery structure is simple, and production efficiency is high, and its packaging effect is good, and can effectively prevent the generation of " the quick-fried slurry of electric capacity " even blast situation, improves the fail safe that condenser type battery is used.
