Abstract
The invention provides an upper cover of a buckling-type double-electric-layer capacitor, belongs to manufacturing of the designs of upper covers of buckling-type double-electric-layer capacitors, and relates to structural improvement of the upper covers of the buckling-type double-electric-layer capacitors. The upper cover of the buckling-type double-electric-layer capacitor is composed of a round-plate-typed upper plate, a connecting portion and a side plate, wherein the connecting portion is connected with the upper plate and bends downwards, and the side plate is connected with the connecting portion and bends upwards. The upper cover of the buckling-type double-electric-layer capacitor is characterized in that the contact portions of the side plate and the connecting portion are completely attached; the bottoms of the side plate and the connecting portion are flat. The upper cover of the buckling-type double-electric-layer capacitor is used for tightly attaching the side plate and the connecting portion, wherein the side plate is embedded and sealed with a lower cover, therefore improvement of flatness of the bottoms is guaranteed, and accordingly the upper cover and a rubber ring obtain better tight-attaching effect, leakage of electrolyte is avoided, quality of the double-electric-layer capacitor is improved, and service life of the double-electric-layer capacitor is prolonged.
Description
Affiliated technical field
The invention belongs to the upper cover design manufacturing of button double electric layer capacitor, the superstructure that relates to a kind of button double electric layer capacitor improves.
Background technology
The button double electric layer capacitor generally has high-energy-density, discharges and recharges frequency than lithium secondary battery outstanding.In recent years, the backup battery that is used as with the close friend's that it was had feature in the portable machine uses.
The upper cover part or the lower cover portion that form double electric layer capacitor have adopted stainless steel, so thermal endurance is very outstanding.Also have, for the cushion rubber of isolating and sealing is made also uses the high-performance industrial plastic, the thermal endurance of this material is also very outstanding.But, occurred causing electrolyte leakage because the sealing of loam cake and lower cover is inadequate during the sealing of high-performance industrial plastic.
Adopt recently the part of O-ring seal in the comprehensive or lower cover portion of cushion rubber to be coated with the method that seals behind the layer sealing agent.But use this method also sealant agent volatilization or the faulty problem of sealant can be arranged in the course of processing of high temperature.
Summary of the invention:
Purpose of the present invention just is to overcome the defective of above-mentioned prior art, and the sealing between a kind of effective increase loam cake and the cushion rubber is provided, thereby prevents the loam cake of the button double electric layer capacitor of electrolyte leakage.
The technical scheme of taking for achieving the above object is:
A kind of loam cake of improved button double electric layer capacitor is comprised of the connecting portion of the upper plate of rondelle, the downward warpage that is connected with upper plate and the upwards side plate of warpage that is connected with connecting portion, and it is characterized in that: described side plate and connecting portion contact portion are fitted fully;
The bottom surface of described side plate and connecting portion is smooth;
The length of the bottom surface tabular surface of described side plate and connecting portion is not less than 0.3mm.
The present invention is used for tightly fitting together with side plate and the connecting portion of the chimeric sealing of lower cover by the loam cake with the button double electric layer capacitor, guaranteed the increase of bottom flatness, thereby make it to be close to better effect with cushion rubber, avoid the leakage of electrolyte, improved quality and the useful life of double electric layer capacitor.
Description of drawings:
Fig. 1 is the single face schematic diagram of instance X axle of the loam cake of improved button double electric layer capacitor of the present invention;
Among the figure: the length alpha of upper plate 111, side plate 112, connecting portion 113, bottom surface tabular surface, bottom surface 21a.
Embodiment:
The loam cake of button double electric layer capacitor of the present invention is comprised of the connecting portion 113 of the upper plate 111 of rondelle, the downward warpage that is connected with upper plate and the upwards side plate 112 of warpage that is connected with connecting portion, and described side plate 112 is fitted fully with connecting portion 113 contact portions;
The bottom surface 21a of described side plate 112 and connecting portion 113 is smooth;
The length alpha of the bottom surface tabular surface of described side plate 112 and connecting portion 113 is not less than 0.3mm.
