Description
Technical field
The present invention relates to a kind of battery connecting wafer structure, specifically be meant a kind of cell connector structure that is used to protect the battery adaptation, belong to the field of cell connector.
Background technology
Progress along with science and technology, personalized electronic product increases day by day, in order to promote the practicality of these products, its design all trend is carried, and battery also becomes the main source of supply of electrical energy, today that environmental consciousness comes back, with being eliminated gradually with the battery of promptly throwing, get and generation be can reusable rechargeable battery, be subjected to the influence of rechargeable battery type, often need a plurality of rechargeable battery series connection could be obtained enough voltage, for reaching its convenience, other special charging battery just be there emerged a at various product integrations in manufacturer.
See also Fig. 1, it is the structural representation of existing rechargeable battery.In cylindrical hollow housing 10, be provided with negative electrode 11, dividing plate 12 and anode 13 at interval, has an insulation board 14 respectively at the two ends of hollow housing 10, after internal structure is finished, intermediary 16 is placed between the Shu end and electrode cap 15 of hollow housing 10, utilize the mode of pressing, electrode cap 15 driving fits are arranged on the housing 10, and become complete battery.
See also Fig. 2, it shows the structural representation of existing integrated rechargeable battery.In housing 2, be equiped with four rechargeable batteries 21,22,23,24, for with these four rechargeable batteries 21,22,23,24 series connection, with battery 21+extremely the go up integrated rectangular cell brace of spot welding 26A, and the other end of cell connector 26A is welded to the utmost point of rechargeable battery 22, with the method with rechargeable battery 22+utmost point is connected in a utmost point of rechargeable battery 23 with cell connector 26B, with cell connector 26C connect rechargeable battery 23+utmost point of the utmost point and rechargeable battery 24, and by conductive component 27A connect battery 21+utmost point, and conductive component 27B connection battery 24+utmost point, dispose four rechargeable batteries 21 with this, 22,23,24 series connection form a battery pack to power.
See also Fig. 3, it shows the part-structure according to the integrated rechargeable battery among Fig. 2.Rechargeable battery the 21, the 22nd utilizes its solder joint 28,29 to electrically connect mutually respectively with cell connector 26A, and battery 21+utmost point is electrically connected at other parts of integrated rechargeable battery with conductive component 27A, battery 22+end is connected to other battery with cell connector 27B.
Yet above-mentioned integrated rechargeable battery set often enters in the battery air because of adaptation reduction between electrode cap and cap, causes the chemical substance liquefaction of negative electrode and anode and the phenomenon of leakage occurs.At first, the phenomenon that adaptation reduces is the process careless mistake owing to the battery body assembling, but thereafter, find this be welded on the electrode cap cell connector in transport, pullling between reason such as use can cause electrode cap and housing, cause the adaptation between electrode cap and housing to reduce.
See also Fig. 4, the stressed and mobile situation of the cell connector in its displayed map 3.When battery 21 is subjected to stress to the right and battery 22 is not subjected to any stress, be connected in the sheet metal that the cell connector 26A of two batteries 21,22 is formed in one, be not easy to produce deformation or mobile, the solder joint 28,29 that then is welded on the cell connector 26A does not also have any moving, because electrode cap 25 is to be pressed on the housing by intermediary, make the configuration instability of electrode cap 25, easily produce mobile because of battery or cell connector are subjected to stress, this kind move will cause and housing between adaptation reduce, and then produce the phenomenon of leakage.
In view of above-mentioned shortcoming, in this technical field, need a kind of battery connecting wafer structure badly, under the situation of the processing procedure that does not change its battery body, the rechargeable battery set that can reduce the cell connector with spot welding causes the not good situation of adaptation because of the stress of the relative motion between battery.
