Description
Technical field
The utility model relates to the various vehicle batteries of a kind of electric power class.
Background technology
The storage battery that existing electronic class vehicle uses, the casing, cap and the electroded pole plate that mainly comprise storage battery, a plurality of containers that its casing is provided with, be provided with pole plate in each container, the capacitor plates both positive and negative polarity that links to each other is connected in series and draws both positive and negative polarity at last power output is provided, and adopts welding method to link to each other between its electrode usually, and it is not enough to form rosin joint, dry joint or contact area easily, the internal resistance of cell is strengthened, influence the charge-discharge performance of battery.The outer glue sealing method of the general employing of the sealing of terminal.Its casing generally uses adhesive structure with cap, after the casing upper edge of battery case is coated with gluing, be embedded in the groove of battery cap, liquid injection hole by the battery cap from outside toward in, inject electrolyte or viscose glue, whole storage battery formed hermetically-sealed construction, its conductive electrode also together viscose glue in battery cover, according to the characteristic standby certain hour of viscose glue or take suitable technological processes such as oven dry, its battery case and lid just bond together then.Because the battery pole plates that links to each other, what use between its both positive and negative polarity is plumbous part Welding Structure, can only use outer glue sealing method sealing, cause electrolyte to ooze out or the phenomenon of leakage easily, the inconvenience of working simultaneously, the manufacturing cycle is long, increased manufacturing cost, influence the area that electrode is set, the battery capacity of limited bulk is restricted, finally can cause reducing of entire cell capacity.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of direct connection and terminal internal enclosed power accumulator, and this storage battery battery capacity is big, and internal resistance is little, and electrolyte content is many, the sealing property height, and manufacturing process is simple, long service life.
The utility model provides following technical scheme, a kind of direct connection and terminal internal enclosed power accumulator, the pole plate that is divided into battery jar and battery cap and band positive and negative electrode, battery jar is a rectangle plastic box, be provided with a plurality of dividing plates in this casing, dividing plate is divided into many group containers with casing, pole plate is arranged in the container, the shape of battery cap and the shape of plastic box adapt, the seam that the upper end of plastic box is provided with is connected mutually with the battery cap inside surface of side wall, battery cap is provided with a plurality of liquid injection holes and two anode and cathode terminals fairleads, and battery cap is provided with cover plate, and the positive pole of adjacent container pole plate and negative pole adopt the direct connection syndeton.
The inboard of described battery cap is provided with for the dark groove of two rows that holds the direct connection electrode, and cooperates many rows shallow grooves of splicing and becoming vertical direction with dark groove with box partition.
Described battery cap outside intermediate lateral is provided with depression, and described liquid injection hole is arranged in the depression.
Power accumulator of the present utility model possesses following advantage: the electrode between pole plate adopts positive and negative associated mode, and the internal resistance of battery is little, and terminal sealing can adopt the double containment mode of the combination of inner and outside, has stopped that electrolyte oozes out or the phenomenon of leakage, good sealing effect.Simultaneously, battery cap is provided with two row's big grooves of hold electrodes, can effectively increase the effective area of pole plate, the pole plate height can increase by 10%, has improved battery capacity, reduces the phenomenon of battery over-discharge, battery life is long, and electrolyte content is many, can effectively avoid the generation of thermal runaway.
Below in conjunction with accompanying drawing the utility model is elaborated.
